[X86] Avoid invalid ret for EH_RETURN with SHSTK (#219322)
## Summary
Fixes #215298
When lowering `llvm.eh.return` on x86, LLVM rewrites the normal stack
return
address and then emits `ret`. This is incompatible with CET shadow
stacks:
the shadow stack still contains the original return address, so `ret`
raises
a control-protection fault.
This affects code using `__builtin_eh_return` with: -mshstk
-fcf-protection=full
## What changed
When SHSTK is enabled, the x86 `EH_RETURN` pseudo-instruction now
expands to:
```asm
movq %rcx, %rsp
popq %rcx
jmpq *%rcx
```
- The `pop` consumes the rewritten return target and advances the stack
pointer.
- `llvm.eh.return` performs a non-local control transfer to an
explicitly supplied handler address, which was never pushed by a
matching `call`. It therefore cannot satisfy `ret`'s architectural
shadow-stack matching requirement regardless of implementation, so
an indirect `jmp` is used instead.
- The existing `mov %rcx, %rsp; ret` sequence is preserved for targets
without SHSTK support.
- The expansion handles 32-bit and 64-bit targets, including the
existing
Windows/UEFI x64 indirect-jump variant.
## Testing
Added: `eh-return-shstk.ll`
The test verifies that:
- non-SHSTK targets continue to emit `ret`
- SHSTK targets emit `pop` followed by an indirect `jmp`
- machine instruction verification succeeds in both configurations
Validation performed:
```bash
ninja -C build llc FileCheck llvm-config count not
build/bin/llvm-lit -sv llvm/test/CodeGen/X86/eh-return-shstk.ll
```
Passed: 1 (100.00%)
The original C reproducer was also compiled with the rebuilt Clang. Its
`pop_frame` function now emits:
```asm
movq %rcx, %rsp
popq %rcx
jmpq *%rcx
```
Runtime execution of the reproducer could not be fully validated because
the
available environment is WSL2 without usable CET shadow-stack support.
The
compiler output and LLVM regression test both pass, but this does not
confirm the control-protection fault is resolved on real CET-enabled
hardware, only that the expected instruction sequence is now emitted.

[MLIR] Fix and classify generated-header dependencies (#222329)
This is fixing missing CMake dependencies to make our build graph
correct. It is a bit verbose but will be cleaned up in a following patch
making handling of the generated header automatic.
List the TableGen targets owned by each affected library, and add the
missing LLVM generated-header, SPIR-V source-generation, OpenACC/OpenMP
generated-input, and CIR operation/type prerequisites found by clean
dependency audits. Correct two stale copy-paste dependencies and the
duplicate CIR link entry.
The Transforms pass declarations and dialect inliner interface are
independent of any dialect. Classify both under mlir-generic-headers,
and associate the inliner interface with MLIRTransformUtils, which
publishes InliningUtils.h. This gives every MLIR library the required
ordering without repeated header-only edges.

[mlir][llvm] Fix metadata and alignment on masked memory intrinsics (#221879)
llvm.intr.masked.load, masked.store, masked.gather and masked.scatter
implemented neither AccessGroupOpInterface nor AliasAnalysisOpInterface,
so they could not carry access_groups, alias_scopes, noalias_scopes or
tbaa. Importing LLVM IR that attached such metadata to one of them
silently dropped it, while llvm.memcpy in the same module preserved it.
Also widen alignment from I32Attr to I64Attr, matching the rest of the
LLVM dialect and LLVM proper, and make it optional. LangRef gives the
default alignment of these four intrinsics as the ABI alignment of the
type, exactly as for llvm.load and llvm.store, so an absent align
parameter attribute now imports as an absent alignment attribute instead
of being materialised as align 1, and an absent alignment attribute
exports without an align parameter attribute. This changes the textual
IR, as alignment = 4 : i32 becomes alignment = 4 : i64. Downstream
updates should rewrite only lines that mention a masked intrinsic rather
than blanket-substituting i32 with i64; other i32 spellings must stay,
including llvm.intr.matrix.*'s rows and columns attributes and i32
vector and element types on the intrinsics themselves.

[openmp] - Remove hwloc INSTALL_INTERFACE on omp target (#218923)
Reasons for removal:
1. hwloc is not present in installed headers, therefore a consumer of
openmp does not need hwloc
2. There is no omp target exported currently, which means
INSTALL_INTERFACE is ignored.
3. If there is a future omp target exported then there is a possible
relocation issue if LIBOMP_HWLOC_INCLUDE_DIR differs in build
environment vs end user's environment.
We need to keep BUILD_INTERFACE for unit testing and ompd build.

[CGP] Drop poison generating flags when pushing freeze through cmp (#222314)
We need to clear the samesign flag when pushing freeze through icmp.
In the last commit, I also adjusted the handling of FMF on fcmp to work
the same way -- previously the transform would be skipped instead if the
fcmp had fast math flags. I think just clearing the poison-generating
flags is preferable (and what we'd do anyway in InstCombine and
DAGCombine).

[llvm-pdbutil] Map enums in bitflags for symbols in YAML (#215887)
Both `S_COMPILE3` and `S_FRAMEPROC` have bitflags that also contain
non-bitflag enums. For `S_COMPILE3`, the lower eight bits represent the
language and for `S_FRAMEPROC` there are bits in the middle representing
the frame pointer registers for variables and parameters.
In both cases, the values of the enums were not present in the generated
YAML.
Mapping this in YAML is a bit complicated, because we can't give
`yaml::IO` a reference to the flags. I used local variables and a check
if we're reading to re-assemble the flags.

[flang] Avoid signed integer overflow in GetNonNegativeExtent (#222207)
`GetNonNegativeExtent()` computes a dimension's extent from constant
bounds as `ub - lb + 1` in `ConstantSubscript` (`int64_t`) arithmetic.
For an oversized dimension such as `integer(1) ::
a(0_8:9223372036854775807_8)`, whose extent is 2\*\*63, that computation
overflows — undefined behavior, and the ubsan failure reported in
#221940.
The wrapped result has to be preserved: storage sequences that are too
large are diagnosed later, while offsets are computed, and that code
tells a genuinely empty dimension from one whose extent wrapped around
by cross-checking the original bounds (`IsEmptyDimension()` in
`Semantics/compute-offsets.cpp`). This patch therefore computes the same
two's complement result with `llvm::SubOverflow()` and
`llvm::AddOverflow()`, which are defined for every input. Subtracting
first also covers bounds of mixed sign, where `ub - lb` can overflow
before the increment.
Fixes #221940

[AMDGPU] Fix invalid 64-bit DPP formed from folding a 32-bit DPP mov (#222216)
GCNDPPCombine already rejects 64-bit DPP when the DPP move itself is
64-bit, but a 32-bit move folded into a source of a 64-bit instruction
was not checked. On targets without FeatureDPALU_DPP this formed
V_LSHLREV_B64_e64_dpp, whose tied old operand got the move's 32-bit
register class instead of the 64-bit destination class.

[CIR] Honor the Direct coercion offset in x86_64 callconv lowering (#220724)
When a record's low eightbyte holds no field, the classifier passes it
in one register read from byte 8 rather than byte 0. CallConvLowering
had no way to represent that, so `convertABIArgInfo` rejected the whole
signature as NYI.
`ArgClassification` now carries the offset and `emitCoercionToMemory`
reads and writes the coerced scalar through a `u8` `cir.ptr_stride` at
that byte. The offset-zero path is untouched.
A register-tuple coercion at an offset is refused rather than read from
the wrong bytes, a pair SysV cannot currently produce.
Drop the pass opt-out flag from one test that no longer needs it.
Supersedes #203640, which had the coercion mechanism but nothing calling
it.

[CodeGen] Visit operands inside bundles in DetectDeadLanes (#220645)
`modifySubRegisterOperandStatus` walked each basic block with
`MachineBasicBlock`'s default iterator, which visits only top-level
instructions and steps over the contents of a `BUNDLE`. Dead/undef flags
were therefore only ever updated on the `BUNDLE` header, even though the
analysis half of the pass walks `MRI` use lists and does account for
bundle-internal operands. The pass reasoned about operands it then refused
to update.
A register referenced both by the header and by a bundled instruction
ends up with the two disagreeing about whether the bundle reads it, and
consumers split on which half they believe: `ScheduleDAGInstrs::buildSchedGraph`
and `LiveIntervals::handleMove` look at the header only, while
`RegisterOperandsCollector` descends into the bundle. The scheduler can
then move a bundle across a dependence it never modelled, and
`RegPressureTracker::recede` asserts on an empty use lane mask.
Walk `MBB.instrs()` instead, so the rewrite sees the same operands the
analysis did.

[InstCombine] Fold comparisons of urem with dividend (#214933)
This folds equality comparisons of `X urem Y` with `X`
- `(X urem Y) == X` to `X ult Y`
- `(X urem Y) != X` to `X uge Y`
For a defined `urem`, let `Q = X udiv Y` and `R = X urem Y`. Unsigned
division gives `X = Q * Y + R`, so:
```
R == X
<=> Q * Y == 0
<=> Q == 0 (since Y != 0)
<=> X < Y
```
Division by zero is undefined behavior, so no separate handling for `Y
== 0` is required.
This handles commuted compare operands, scalar and vector types, and
remainders with additional uses

[SDAG][ComputeNumSignBits] Look through undefined high bits for EXTRACT_VECTOR_ELT in a BUILD_VECTOR (#218099)
If we have a `BUILD_VECTOR(EXTRACT_VECTOR_ELT()...)` where the
`EXTRACT_VECTOR_ELT` is adding undefined high bits by extending but the
`BUILD_VECTOR` is again truncating those bits, then we can just look
through the extract and call `ComputeNumSignBits` directly on the parent
vector.
Ideally, when the caller is truncating the value, it would be nice for
`ComputeNumSignBits` to have the ability to ignore high bits we don't
care about.

[clang][CodeGen] Fix assertion failure with #embed in array new-expression initializers (#218262)
Fixes #128985
An `EmbedExpr` in a semantic initializer list can represent many array
elements at once, and every consumer of such lists has to expand it. The
array `new` emitter, `EmitNewArrayInitializer`, never did: it counted
the `EmbedExpr` as one element and emitted it through the scalar path,
hitting `assert(E->getDataElementCount() == 1)`. The undercount also
made the runtime minimum allocation check too lax and miscomputed the
trailing zero-fill size.
`Codegen` now emits one store per embed data element, converted to the
element type, and counts initializers with
`getNumInitsWithEmbedExpanded()` in both places. That helper also
learned to look through implicit casts, since Sema wraps a multi-element
`EmbedExpr` in a conversion when the element type isn't `int` — the
other embed consumers already strip casts before checking.

[SystemZ] XPLINK64: use AExt for 32-bit pointer formals (#222350)
CC_XPLINK64_Pointer was setting LocInfo=ZExt, promising the optimizer
that the caller had zero-extended bit 32. Evidence from Open XL 1.1 and
2.2 shows that callers do not consistently zero-extend `__ptr32`
arguments
-- Open XL 1.1 emits nothing on the caller side; Open XL 2.2 only
zero-extends in the explicit cast case. Every actual use of a 31-bit
pointer goes through `addrspacecast` which emits `LLGTR` to clear bit 32
at
the point of use, so no callee relies on the register being clean at the
parameter boundary. Change LocInfo to AExt to accurately reflect that
only the low 32 bits are valid.
Extracted from #206833 per reviewer request.

[Clang][Sema] Error message refers to `__begin1` with `constexpr` variable in range-based for loop (#218145)
Fixes #211926
When a range-based for loop variable is declared `constexpr`, its
initializer is the compiler-built `*__begin1`, which normally can't be a
constant expression. The constant evaluator reports what it sees at the
leaf — `read of non-constexpr variable '__begin1' is not allowed in a
constant expression`, plus a `declared here` note pointing at the loop's
colon — without saying what `__begin1` is.
Both constant evaluators now emit a single dedicated note when they read
one of the loop's implicit variables, so the existing `constexpr
variable 'x' must be initialized by a constant expression` error is
followed by `'__begin1'-variable of range-based 'for' loop is not a
constant expression`, pointed at the loop it belongs to. The note takes
the variable as an argument, so it names `__end1` or `__range1` when
those are what was read. No Sema changes. A constexpr loop variable that
*is* valid (CWG1204, when `operator*` never reads the iterator) still
compiles, and expansion statement (`template for`) variables are
unaffected since their synthesized iterators are themselves `constexpr`.

[clang] Reject references to vector types in `__builtin_vectorelements` (#219767)
Fixes #216997
`__builtin_vectorelements` shares its operand check with `sizeof` and
friends, and that shared code looks through reference types before it
dispatches to the per-builtin check. So `__builtin_vectorelements(veci4
&)` was accepted by Sema, but the expression kept the reference as its
argument type, and everything downstream — constant evaluation, the
bytecode interpreter, CodeGen — expects that type to be a vector.
Constant-evaluating the initializer in the reproducer then trips
`assert(Ty->isSizelessVectorType())`. The alias syntax in the report
isn't the cause; `vec` there is a well-formed reference-to-vector type.
The check now runs before the reference is looked through, so a
reference to a vector type gets the existing "must be of vector type"
error, the same one `__builtin_vectorelements(int &)` already produced.
No other trait kind is affected.

[SystemZ] XPLINK64: emit narrow sign/zero-extend instructions for sub-i32 formal args (#206833)
Previously, i8/i16 integer formal arguments with signext/zeroext
attributes were promoted to i64 via CC_XPLINK_Promote_i32 using
LocVT=i64, causing the DAG to select LGFR/LLGFR (word-sized extends) for
all sub-i64 types instead of the narrower byte/halfword forms required
for XL compiler binary compatibility.
Root cause: LLVM type-legalizes i8/i16 to i32 before the CC table runs,
so ValVT is always i32 by the time CC_XPLINK_Promote_i32 is called. The
pre-legalization original type (Ins[i].ArgVT) is the only way to
distinguish i8/i16 formals from i32 formals at that point.
Fix:
- Add ArgOrigVTs to SystemZCCState, populated in AnalyzeFormalArguments
from Ins[i].ArgVT (using MVT::Other as sentinel for non-simple EVTs),
with a getArgOrigVT(ValNo) accessor that returns MVT::Other safely when
called outside AnalyzeFormalArguments (e.g. from AnalyzeCallOperands).
- In CC_XPLINK_Promote_i32 with isFormalArgLowering=true: for original
i8/i16, keep LocVT=i32 (GR32 live-in) only when a GPR is still available
(probed via getFirstUnallocated([R1L,R2L,R3L])). When all GPRs are
taken, the arg goes to an 8-byte stack slot where the caller stores a
sign-extended i64 with the value in bytes 6–7; LocVT=i64 is used in that
case so the full 8 bytes are loaded correctly.
- In LowerFormalArguments: after convertLocVTToValVT, truncate from the
legalized i32 down to the true i8/i16 so the DAG folds the
truncate+extend into a narrow instruction. Guarded by isTargetXPLINK64()
and ArgVT.isSimple().
- Extend CCIfType from [i32] to [i8, i16, i32] in CC_SystemZ_XPLINK64.
Result — callee side:
| Type | Attribute | Before | After |
|------|-----------|--------|-------|
| `i8` | `signext` | `LGFR` / `LGF` | `LGBR` / `LGB` |
| `i8` | `zeroext` | `LLGFR` / `LLGF` | `LLGCR` / `LLGC` |
| `i16` | `signext` | `LGFR` / `LGF` | `LGHR` / `LGH` |
| `i16` | `zeroext` | `LLGFR` / `LLGF` | `LLGHR` / `LLGH` |
| `i32` | `signext` | `LGFR` | `LGFR` (unchanged) |
Binary compatibility analysis:
The XPLINK64 ABI requires every caller to deliver a fully
sign/zero-extended 64-bit value in the argument register before the
call, regardless of the original type width. This patch only changes the
callee-side re-extension instruction; the caller side (LowerCall /
AnalyzeCallOperands) is unchanged and continues to emit LGFR/LLGFR for
outgoing sub-i32 arguments, or LGB/LGH/LLGC/LLGH when loading directly
from memory.
Because any ABI-compliant caller always delivers a full 64-bit
sign-extended value, bit 7 (for i8) or bit 15 (for i16) is always the
authoritative sign bit in the incoming register. Re-extending from that
bit with LGBR/LGHR yields the same result as LGFR from bit 31. The
matrix below covers all mixed-version combinations:
| Caller | Callee | Register value at call site | Callee re-extension |
Correct? |
|--------|--------|-----------------------------|---------------------|----------|
| Any (memory load) | new | `LGB`/`LGH` → full i64 | `LGBR`/`LGHR` | ✓
bit 7/15 intact |
| Open XL 1.1 | new | full GR64, no extend needed | `LGBR`/`LGHR` | ✓
ABI-compliant i64 |
| Open XL 2.2 | new | `LGFR` → full i64, bit 7 = sign | `LGBR`/`LGHR` |
✓ bit 7 intact |
| new | Open XL 2.2 | `LGFR` (caller side unchanged) | `LGFR` | ✓
identical to before |
| new | Open XL 1.1 | `LGFR` (caller side unchanged) | none (trusts
GR64) | ✓ GR64 is valid |
| Java/JNI | new | no extend (raw GR64 from JVM) | `LGBR`/`LGHR` | ✓ JVM
guarantees full i64 per JNI spec |
| new | Java/JNI | `LGFR` (caller side unchanged) | none | ✓ GR64 is
valid |
No binary incompatibility in any direction.
Adds lit test zos-xplink64-formal-sub64-extend.ll covering all five
integer types, the optnone spill path, and small struct coercion cases.
Updates call-zos-01.ll and call-zos-vararg.ll.

[libc++] Remove `_LIBCPP_EXPLICIT_SINCE_CXX14` (#222221)
The existence of `_LIBCPP_EXPLICIT_SINCE_CXX14` is a relic of the
questionable status quo of LWG2176 - we only implement its resolution
since C++14 mode (7988106b21628afe7004b57ae66ec9b43cbc8942). In
a11f8b1ad66d68ca0a3a277ce776007abff9c7eb
(https://reviews.llvm.org/D91292), we implemented P0935R0 as a Defect
Report against C++11, and P0935R0 somehow superseded LWG2176. So it is a
bit unreasonable to leave LWG2176 not backported.
This patch backports the remaining parts of LWG2176 to old modes. As the
copy constructor of `wbuffer_convert` and `wstring_convert` are deleted,
implicit conversions to them cannot be performed in C++03 even if the
related converting constructors lack `explicit`.
As drive-by, also drops `// C++20` comments on these constructors due to
P0935R0 and `// C++14` comments due to LWG2176.

[CMake] Add dependent project mode for Flang's MLIR (#221724)
`LLVM_ENABLE_PROJECTS` historically treats projects enabled to satisfy
another
project's dependency the same as projects selected by the user.
Consequently,
implicit projects attach their complete build, install, and test suites
to
LLVM's aggregate targets.
Keep the cache entry as the user-requested project roots and use the
normal
`LLVM_ENABLE_PROJECTS` variable as the effective dependency closure.
Projects
in the effective list but not the cache entry are configured with
`EXCLUDE_FROM_ALL`. Normalize the special `all` value before comparing
the two
sets.
This makes Flang's MLIR and Clang dependencies dependency-only without a
second
project collection. It also applies the same rule to Clang when it is
added for
LLDB. Forward the cached roots to cross-compilation and bootstrap
configurations so implicit projects do not become explicit in nested
builds.
Let MLIR own its dependency-only test policy: configure its complete
test tree
so `check-mlir` remains available, but exclude MLIR test execution and
build
dependencies from `check-all`. Explicitly enabling MLIR preserves the
existing
behavior.
Validation:
- Configured Flang with implicit MLIR test support.
- Configured Flang and MLIR explicitly with tests enabled.
- Configured `LLVM_ENABLE_PROJECTS=all` with tests disabled.
- Verified implicit mode exposes `check-flang` and `check-mlir` while
`check-all` runs Flang but not MLIR.
- Verified explicit mode includes MLIR tests in `check-all`.

After #215402, peelZeroOffsetViews walked through fir.convert that
changes the pointee type (e.g. !fir.ref<complex<T>> → !fir.ref<T>).
Load/store then indexed the parent array and converted the value, which
is wrong for Fortran storage association: it fails verification
(memref.store / illegal fir.convert) or silently changes bits (sitofp /
fpext).
Stop peeling when the accessed element type changes. Marshal the typed
view as a rank-0 memref of the dummy type. Same-type wrappers
(fir.declare, ref<T> → ref<T>) still peel to fir.array_coor.

#197237 dropped the `.noindex` suffix from the test build directory on

`lldb-test-build.noindex`. In Swiftlang, every test that invokes it
fails off Darwin:
```
Makefile.rules:741: *** Trying to invoke the clean rule, but not using the default build tree layout. Stop.
```
Match `lldb-test-build` instead, which covers both layouts and keeps the
guard's intent of not letting the rule loose on an arbitrary directory.

[LLVM][libc] Defer lowering of constant intrinsics in full LTO (#221505)
Summary:
This PR defers the lowering of the constant intrinsics. Currently it was
inheriting the default module pipeline and being done pessimistically in
the pre-link LTO phase. This means that some objects which would become
known constants were returned as failures. Doing this in the post-link
phase is more optimistic.
I included the `libc` change that justifies this in the PR, but it can
be split out if needed. The observation is that the ExpandVariadics pass
will lower most variadic calls on the GPU to an alloca of known size.
Using this opportunistically saves us a spill to stack ordinarily needed
to copy back the size from the GPU. Without this, every use of GPU
printf resulted in a spill to stack memory.
Hopefully this is benign enough.

An unrecognizable statement in the execution part of a source file
produced one "expected 'KEYWORD'" error for every possible statement
because each execution-part-construct alternative failed at the same
source position and the alternative combinator merges the messages of
same-position ties.
Wrapped the keyword-led alternatives in `withMessage` so that when none
of them matches a token, the flood is discarded in favor of a single
"expected an executable statement" diagnostic.
This fixes the problem identified in Issue:

[NFC][analyzer] Cleanup checker calls in `ExprEngine::ProcessStmt`, `ExprEngine::Visit*` (#218691)
Begin standardizing how `PreStmt` checkers and `PostStmt` checkers are
called by the analyzer engine. Previously, checkers were called either
from `ExprEngine::Visit` or the visit method of the statement. Now this
logic was hoisted out into `ExprEngine::ProcessStmt` and most of the
checker calls happen from there.
There are several statement kinds that do not call checkers at all or
only call `PreVisit` or only call `PostVisit` checkers. There are also
statement kinds whose visit code does not easily lend itself to the
`PreVisit`, `Visit`, `PostVisit` scheme, so those have been left
unmodified and will be refactored in a separate patch. The checker

[flang][cuda] Emit Mcuda_compiled sentinel for CUDA Fortran objects (#222421)
Objects compiled as CUDA Fortran now declare an undefined Mcuda_compiled
symbol from CUFAddConstructor when emit-cuda-compiled is set. Linking
without the CUDA Fortran runtime then fails with a clear undefined
reference instead of only _FortranACUFInit, which is limited to PROGRAM
units.
The CUDA Fortran runtime defines the symbol so linking with the CUDA
Fortran runtime still succeeds.

[Clang][Sema] Make _Imag int/float LValue not assignable (#218270)
Clang accepts `__real int/float` as an LValue because it's equal to the
scalar value itself, so the assignment will work fine, but it's not the
case for `__imag` because, for int and float, there is no imaginary part
to assign a value to it, so in the sema we can reject this case, similar
to GCC.

Give each lane its own allocation when `ThreadX` is active and the shape

`processPrivatize` published a single allocation through a workgroup
slot indexed by `ThreadY`, so all lanes of a worker ended up sharing one
buffer.

[CodeGen] Relax an overly strict assert in EmitAggregateCopy (#219090)
EmitAggregateCopy contains a sanity check verifying that a record being
bitwise copied has a genuinely trivial copy/move constructor or
assignment operator. The check did not account for records that are
non-trivial only because they contain an ARC __strong field. Such
records are still trivial for the purposes of calls, so clang can
legitimately use memcpy to copy them when passing or returning the type
by value.
Relax the assertion by using hasTrivialCopyConstructorForCall() and
hasTrivialMoveConstructorForCall() instead of the plain
hasTrivialCopyConstructor()/hasTrivialMoveConstructor() checks, since
these are exactly the predicates that capture that notion of triviality
for calls. This also makes the separate hasAttr<TrivialABIAttr>() check
redundant, since the trivial_abi attribute unconditionally sets the
for-call bits for the copy constructor, move constructor, and
destructor.

[MLIR][LLVM] Enable strict property assembly format (#217277)
Enable strict property assembly format mode for the LLVM dialect. Bind
LLVM operation properties directly in declarative assembly formats so
strict parsing does not rely on fallback handling.
Update LLVM dialect, target, and conversion tests to use the direct
property spelling.

[CIR][CMake] Configure MLIR as a dependency-only project (#221739)
Enable MLIR implicitly for ClangIR without attaching its unrelated tools
and test suite to the aggregate build. An explicit MLIR selection
retains its normal behavior. Add MLIR after all Clang consumers enable
Clang, so CIR also works when Clang is enabled for LLDB.
Package the required MLIR libraries through Clang's existing exports and
LLVM's distribution policy. Register dependency library and header
install components and honor toolchain-only installations. When Clang is
itself an implicit Flang dependency, let Flang package the required
targets.
Keep MLIR test support available for CIR and retain the standalone
ClangIR restriction. Leave MLIR disabled when CIR is disabled.

[CIR] Fix CIR tests by adding a triple/Requires. (#222346)
Now that we're trying to build by default, we actually have to be able
to build on other buildbots! But since we still don't have the
ABI/target stuff for non linux, we need to make sure our tests don't hit
that. Tests that execute 'clang' in some way are given a triple, ones
that are on .cir files we just add a 'requires'. Some day we should be
able to remove those, but it'll require us to add the cxxabi/etc for
windows.

[Clang][OpenACC] Fixed getExtValue Call on Invalid Gang Dim (#221502)
**Problem**
When an invalid 'gang dim' value is used in `CheckGangDimExpr`, the
function prints the value into the diagnostic message by calling
`getExtValue`. This function asserts on values that can't fit into a
signed integer.
**Solution**
`APSInt` has a `<<` operator anyway so just use that.
The fix causes the message to print with the following formatting:
```
test.cpp:5:40: error: argument to 'gang' clause dimension must be 1, 2, or 3: evaluated to 18'446'744'073'709'551'574
5 | #pragma acc routine(S::foo) gang(dim : S::foo())
| ^
1 warning and 1 error generated.
```

[clang] Warn on signed char array constant conversion (#203792)
This resolves #181730: fixes a missing `-Wconstant-conversion`
diagnostic for `signed char` array initialization.
Before this change, Clang warned for `signed char foo = 255;` but did
not
warn for `signed char bar[] = {255};`.
The warning suppression helper did not distinguish between `char`,
`unsigned char`, and `signed char` in brace-initialized arrays. Now it
does.

-----------
[SPIRV] Fix inconsistent operand order for counter resource intrinsic (#221646)
The `llvm.spv.resource.handlefrombinding` intrinsic stores its binding
operands in the order (DescriptorSet, BindingNo, ...). The
`llvm.spv.resource.counterhandlefrombinding` intrinsic should use the
same order.
The `llvm.spv.resource.counterhandlefrombinding` intrinsic is currently
emitted only by the `SPIRVLegalizeImplicitBinding` pass. The pass
previously built its operands in the wrong order, and the instruction
selector repeated the same inversion when emitting decorations.
This change makes the operand order consistent with
`llvm.spv.resource.handlefrombinding`.
Test update closes a coverage gap - there were no tests for explicit
`llvm.spv.resource.counterhandlefrombinding` calls.

[NFC][AMDGPU] Remove unused MC insts in isPackedSingleSGPR64BitInst (#222463)
There is no opsel support for these instructions, and thus we do not have
to manipulate opsel at MC layer. As a result, isPackedSingleSGPR64BitIns
is currently only used before pseudo-expansion. So we remove MC instruction
check inside.

[AMDGPU] Add missing attributes to llvm.amdgcn.init.whole.wave (#222493)
`llvm.amdgcn.init.whole.wave` only sets the EXEC mask and reports
whether the lane was active on entry. It never calls into the module,
never frees memory, and always returns, so it can carry `nocallback`,
`nofree`, and `willreturn`.
The neighboring `llvm.amdgcn.init.exec` and
`llvm.amdgcn.init.exec.from.input` already have all three; this brings
`init.whole.wave` in line and lets the attributor propagate them to
callers.

[CIR] Add offload container attribute (#206576)
Introduce `cir.offload.container`, a CIR dialect unit attribute that marks an
MLIR module as holding a host CIR module and its associated device CIR
modules in one IR unit while later offload merge/split pipeline passes need
visibility into both sides.
The marked module's body holds nested `builtin.module` operations. Each
nested module is tagged with `cir.offload.kind`, represented by the new
`#cir.offload_kind<host>` / `#cir.offload_kind<device>` enum attribute.
The structural contract expected by the follow-up pipeline work is
enforced in `CIRDialect::verifyOperationAttribute`, following the
`gpu.container_module` precedent:
* `cir.offload.container` is a unit attribute attached to a
`builtin.module`
* the first nested module is the host module
* all following nested modules are device modules
* the body contains only nested `builtin.module` operations
* at least one device module is present
* `cir.offload.kind` is only ever attached to a `builtin.module`
This patch only introduces the IR representation and verifier tests. The
passes that create, consume, or split this container are left to follow-up
patches.

- Add a `ThreadsetPolicy` enum (`omp_pool`/`omp_team`) and clause on `omp.task` and `omp.taskloop.context`, lowered from Flang.
- Translate `threadset(omp_pool)` to the free-agent task flag (`0x80`); `omp_team` leaves it unset, matching clang.
- Add semantics, lowering, and translation tests.

[RegAllocFast] Give an undef tied use the register of its tied def (#222249)
X86TargetLowering::emitSetJmpShadowStackFix zeroes a register by
building an XOR whose two uses are undef reads of its own def (per
MachineOperand.h "... reading the same dont-care value"). Def processing
frees a def whose tied use is undef before the uses are allocated, so
allocVirtRegUndef() no longer finds the virtual register and takes the
head of the allocation order instead. -verify-machineinstrs would fail:
```
renamable $rcx = XOR64rr undef renamable $rax(tied-def 0), undef renamable $rax, implicit-def dead $eflags
*** Bad machine code: Tied physical registers must match. ***
```
Take the register from the tie, and rewrite the instruction's other
reads of the value with it so that they keep agreeing on one register.

[BOLT][AArch64][Android] Recover from dump failure instead of exit (#221292)
Embedded in Android app, failed assert() or reportError() during a BOLT
profile dump should not exit the host process. Install a recovery point
in __bolt_instr_data_dump(), so any failure can longjmp back, return a
non-zero value to caller, and set a flag so later dumps can be skipped.
Clang does not support __builtin_setjmp/longjmp for the AArch64 Android
target, so add a minimal hand-written setjmp/longjmp in sys_aarch64.h.
Since the majority Android apps run on AArch64 CPUs, while at this I
defined `ANDROID_AARCH64` and replaced `__ANDROID__` with it in the
instrumentation runtime code.

[BOLT][ICP] Use PC-relative instructions for x86 PIC binaries in ICP (#216587)
Currently, BOLT x86 ICP optimization inserts an immediate-to-register
comparison instruction, which forces the use of 32-bit signed (32S)
relocations due to ABI limitations. This behavior does not align well
with the conventions of PIC/PIE binaries and **makes it highly prone to
JITLink relocation overflow errors when dealing with large binaries.**
Therefore, this patch introduces an additional lea instruction for the
x86 architecture to leverage PC-relative (32PC) addressing. This change
is intended to apply by default to PIC binaries, or when specific
options are provided.

[LLVM][NVPTX][MLIR] Support layouts in mbarrier.init and add mbarrier.check_layout (#217252)
This commit adds LLVM NVPTX and MLIR NVVM support for the mbarrier layout extensions:
- llvm.nvvm.mbarrier.init with trailing immarg `layout` operand, and nvvm.mbarrier.init a matching `layout` attribute (default to 0) Layout 0 is the default in-memory layout and is emitted as a plain mbarrier.init; layout 1 is emitted as mbarrier.init.layout::v1.
- llvm.nvvm.mbarrier.check_layout / nvvm.mbarrier.check_layout, lowering to mbarrier.check_layout.layout::v{0,1}.
Only the layout::v1 form of mbarrier.init and mbarrier.check_layout require PTX ISA 9.3 and sm_90
llvm.nvvm.mbarrier.init{.shared } are also merged into a pointer-overloaded llvm.nvvm.mbarrier.init with calls to either older forms auto-upgraded
Please refer [PTX ISA](https://docs.nvidia.com/cuda/developer-preview/13.4/parallel-thread-execution/index.html)

[Lifetime Safety] Name operator calls in alias-chain diagnostics (#221803)
This updates Lifetime Safety alias-chain diagnostics to identify
overloaded operator and conversion calls instead of describing them
generically as an `expression`.
Previously, these calls were reported as `expression aliases the storage
of ...`, which could make it unclear which operation introduced the
alias. The diagnostic now reports the callee using the existing
diagnostic name printer, producing descriptions such as:
- `result of call to 'operator->'`
- `result of call to 'operator()'`
- `result of call to 'operator basic_string_view'`
Template arguments are preserved for operator function-template
specializations. For example:
- `result of call to 'operator+<const int>'`
- `result of call to 'operator-<__gnu_cxx::basic_iterator<const int>>'`
This makes each aliasing step explicit and identifies the particular
call responsible for propagating the alias.

[Windows] Don't export clang::interp symbols for plugins (#221295)
With `LLVM_EXPORT_SYMBOLS_FOR_PLUGINS=ON`, `clang.exe` built from the
23.x release branch exports 66679 symbols on x86_64 Windows, over the
65535 limit of the PE export table, so it no longer links:
```
lld-link: error: too many exported symbols (got 66679, max 65535)
```
For comparison, the same configuration on 22.1.8 exports 65465 symbols,
so the headroom was already almost gone.
`clang::interp`, the constant expression bytecode interpreter, accounts
for roughly 4500 of the exported symbols (counted with `llvm-readobj
--coff-exports` on a linked aarch64 23.1.0 `clang.exe`). Its headers
live in `clang/lib/AST/ByteCode` and are not installed; the only mention
in a public header is the forward declaration of `interp::Context` in
`ASTContext.h`. A plugin cannot call into it, so there is no reason to
keep exporting it. Filtering it out follows the existing
`dump`/`dumpColor`/`printPretty` exclusions in
`should_keep_microsoft_symbol`.
Related: #87865 (open; earlier rounds #60109, #56109). This does not get
the MSVC-with-examples configuration from that issue under the limit by
itself, but it removes the largest block of symbols that can never be
used by a plugin, and is what gets the Firefox clang 23 toolchain
(x86_64-pc-windows-msvc, X86;ARM;AArch64;WebAssembly,
clang+lld+clang-tools-extra) from 66679 to roughly 62100 exports.

[Windows] Export Registry<T> members and accessors for plugins again (#221296)
Since #185141 reworked `llvm::Registry`, the registered-node list lives
behind the explicitly specialized
`llvm::detail::getRegistryLinkListInstance<R>()` accessor defined by
`LLVM_DEFINE_REGISTRY`, and the `Head`/`Tail` static data members that
used to be referenced across objects are gone (#163391 had special-cased
those).
`extract_symbols.py` handles neither. The accessor is a `??$` function
template specialization, which the script drops on the assumption that
it can be instantiated in the importing translation unit; here it
cannot, it is defined once by `LLVM_DEFINE_REGISTRY`. And `Registry<T>`
members are only exported when some object references the `Registry`
template, which nothing does anymore because every use goes through the
accessor. On a static clang.exe built with
`LLVM_EXPORT_SYMBOLS_FOR_PLUGINS`, the export table went from 11
`Registry<clang::PluginASTAction>` symbols on 22.1.8 to zero on 23.1.0,
and linking a plugin fails:
```
lld-link: error: undefined symbol: __declspec(dllimport) public: static void __cdecl llvm::Registry<class clang::PluginASTAction>::add_node(class llvm::Registry<class clang::PluginASTAction>::node *)
>>> referenced by host_Registration.obj:(_GLOBAL__sub_I_Registration.cpp)
```
Keep the accessor specializations, and treat a reference to an accessor
as a reference to the `Registry` template so its explicitly instantiated
members are exported as they were before. Verified on the 23.1.0 static
libraries: `Registry<PluginASTAction>::add_node`, the node/iterator
members and the accessor come back for every registry (PluginASTAction,
PragmaHandler, GCStrategy, GCMetadataPrinter, ...), 141 symbols in total
in the Itanium run over the clang libraries. The `Head`/`Tail` rule from
#163391 no longer matches anything and is dropped.
Related: #163367 / #163391 (the previous Registry export fix), #87865.

[llvm-rc] Add /showIncludes dependency reporting (#217102)
Add `/showIncludes` support to `llvm-rc` so build systems can discover
the files a resource compile depends on. This enables Ninja and other
build systems to track and correctly recompile the `.rc` file when
inputs change.
Two kinds of dependencies are reported:
- Preprocessor header dependencies, by forwarding `--show-includes` to
the clang preprocessor.
- Resource files, (bitmaps, icons, manifests, etc) that are used in the
resource file.
The output format matches the `/showIncludes` format that cl.exe and
clang-cl.exe use, and that Ninja can consume natively via `deps=msvc`.

This uses the recently introduced opaque pointers for what we used to

This of course means we see opaque pointers in a lot more places.
However, we don't need to actually allocate anything for their data
anymore, resulting in a lot fewer allocations for such pointers.

[libc++][pstl] Implementation of parallel std::minmax_element() based on parallel reduce (#221572)
This PR adds an implementation of parallel `std::minmax_element()` based
on parallel reduce.
The implementation formulates `minmax_element` as a reduction of
iterators over the input range.
The iterators are first transformed into a min-max iterator pair.
The reduction is provided in two forms: 2-element reduction that makes
an iterator pair pointing to a smaller and a greater value, and a
range-based reduction with init value.
The latter delegates the heavy-lifting to the serial implementation of
`std::minmax_element()`.
Part of #99938.

[AMDGPU] Use new CSR cost calculation (#219220)
So far, AMDGPU backend relied on the legacy calculation for the cost of
the first use of a callee-save register. This legacy path scales the
entry block frequency by a fixed value, making a comparison with
alternatives, e.g., rematerialization, difficult due to different
scales. One example for that is the work in
https://github.com/llvm/llvm-project/pull/206756, where comparison of
rematerialization cost and first use of a CSR is hard to compare due to
the different scales.
Change to instead use the new calculation path with different target
hooks for better comparability.
As the new scale is different, the cost was changed. The new cost value
accounts for various factors impacting CSR cost.
This change (with different cost value) was originally part of
https://github.com/llvm/llvm-project/pull/202007. Another part of that
PR was already extracted into
https://github.com/llvm/llvm-project/pull/214857.

[AArch64][NEON] Fold insert(zero, extract(X, 0), 0) -> X when X is known to zero lanes 1-N (#213940)
Add patterns for NEON across-lane reductions whose scalar result
is inserted into lane zero of a zero vector.
This is valid because these instructions place their result in lane zero
and
clear the remaining lanes.
Limit this change to matching input and result vector types. Mixed
vector
sizes and scalar conversions are not part of this PR.
Handle llvm.vector.reduce.add.v2i64 separately because it lowers to
ADDP.
NEON has no equivalent instruction for v2i64 signed or unsigned min/max
reductions, so they cannot use this fold. Double-precision
floating-point
reductions are already handled by pairwise instruction patterns.

[orc-rt] Express CI symbols as C-level names (#222564)
Controller-interface wrapper functions are now declared extern "C",
exported, and registered under their C-level names, so that they resolve
identically whether looked up through the bootstrap symbol map or via
dlsym.
In addition to removing the inconsistency between the symbol-table and
dlsym names, making CI functions public declarations allows unit tests
to call CI wrappers directly (rather than having to resigster them and
then look them up in a symbol table).
ORC_RT_SPS_WRAPPER and ORC_RT_SPS_ALLOC_ACTION each split into _DECL and
_IMPL forms sharing a _SIG macro, giving the wrappers extern "C" linkage
and an ORC_RT_C_EXPORT annotation.
SimpleSymbolTable::addUnique now takes SymbolNameSpec names and mangles
them, with a second overload for merging one table into another.

[mlir-translate] Move InitLLVM ownership to the standalone tool (#222570)
Please Read: [RFC: Embeddable LLVM tool drivers for long-lived
hosts](https://discourse.llvm.org/t/rfc-embeddable-llvm-tool-drivers-for-long-lived-hosts/91754)
and [Why `InitLLVM` ownership matters section in the
RFC](https://discourse.llvm.org/t/rfc-embeddable-llvm-tool-drivers-for-long-lived-hosts/91754#p-367966-why-initllvm-ownership-matters-7)
`mlirTranslateMain` currently constructs `InitLLVM` internally. This is
fine when `mlir-translate` runs once as a standalone executable, but it
does not work for an in-process setting where the host remains alive and
invokes multiple LLVM tools. When `mlirTranslateMain` returns, the
`InitLLVM` destructor calls `llvm_shutdown()` and destroys
process-global `ManagedStatic` state that may still be needed by the
host and subsequent tool invocations.
[WasmBolt](https://github.com/anutosh491/WasmBolt) (try
[here](https://anutosh21.github.io/WasmBolt/)) is a concrete example of
such a host. It runs Clang, `mlir-opt`, `opt`, `llc` and LLD inside one
browser-hosted LLVM process, allowing users to inspect and transform
code without a remote compilation server.
As described in the [MLIR section of the
RFC](https://discourse.llvm.org/t/rfc-embeddable-llvm-tool-drivers-for-long-lived-hosts/91754#p-367966-mlir-13),
the real `mlir-opt` driver already works in this environment.
`MlirOptMain` does not own `InitLLVM`, so the surrounding host can
control the process lifetime. `mlirTranslateMain` does not currently
provide the same ownership boundary, which prevents us from integrating
it in the same clean way.
The working `mlir-opt` pipeline can be seen here:
https://www.youtube.com/watch?v=yga2lWelne4
This patch makes the two MLIR driver interfaces consistent by moving
`InitLLVM` from the reusable `mlirTranslateMain` entry point into the
standalone `mlir-translate` executable:
```text
standalone:
main -> InitLLVM -> mlirTranslateMain -> process exit
embedded:
host-owned InitLLVM / LLVMToolSession -> mlirTranslateMain
```
Standalone behaviour remains unchanged, while MLIRTranslateLib can now
borrow the process lifetime owned by a long-lived host.

[llc] Add a reusable LLVMLlcDriver library (#221896)
Please read :
[RFC](https://discourse.llvm.org/t/rfc-embeddable-llvm-tool-drivers-for-long-lived-hosts/91754)
and [RFC
section](https://discourse.llvm.org/t/rfc-embeddable-llvm-tool-drivers-for-long-lived-hosts/91754#p-367966-proposed-first-change-llvmllcdriver-8)
This splits `llc` into a small standalone executable and a reusable
`LLVMLlcDriver` library.
The change follows the structure introduced for `opt` by @wsmoses in
[#79205](https://github.com/llvm/llvm-project/pull/79205): the
command-line implementation moves into a driver library, while `llc.cpp`
remains the standalone entry point and continues to own `InitLLVM`.
The immediate motivation is embedding `llc` in long-lived applications
such as [WasmBolt](https://github.com/anutosh491/WasmBolt) (try
[here](https://anutosh21.github.io/WasmBolt/))
Currently, embedders must compile and modify a copy of `llc.cpp` because
the implementation and `main()` live in the same translation unit. This
split provides a reusable entry point without changing the behavior of
the
standalone `llc` executable.

[MLGO] Gate model tests on optimization-specific lit features (#217906)
### Context
`have_mlir_lowering` only indicates that `LLVM_MLGO_MODELS` is
non-empty. It does not identify which model type was compiled.
### Motivation
An inliner-only configuration incorrectly enabled regalloc-specific test
commands, and vice versa.
### Changes
Add `have_mlir_lowering_inliner` and `have_mlir_lowering_regalloc` lit
features derived from the corresponding model-generation targets. Update
MLGO tests to use the appropriate model-specific feature, including GN
configuration defaults.
I leveraged AI to write this PR.

[opt] Move InitLLVM ownership to the standalone entry point (#222559)
Please Read: [RFC: Embeddable LLVM tool drivers for long-lived
hosts](https://discourse.llvm.org/t/rfc-embeddable-llvm-tool-drivers-for-long-lived-hosts/91754)
and [Why `InitLLVM` ownership matters section in the
RFC](https://discourse.llvm.org/t/rfc-embeddable-llvm-tool-drivers-for-long-lived-hosts/91754#p-367966-why-initllvm-ownership-matters-7)
`LLVMOptDriver` is already separated from the standalone `opt`
executable, but `optMain` currently constructs `InitLLVM` internally.
This means its destructor calls `llvm_shutdown()` whenever one driver
invocation finishes.
That is appropriate for a standalone executable, but not for a reusable
driver called by a long-lived host. For example,
[WasmBolt](https://github.com/anutosh491/WasmBolt) (try
[here](https://anutosh21.github.io/WasmBolt/)) invokes `opt`, `llc`,
Clang and LLD within one browser-hosted LLVM process and needs the LLVM
process state to remain alive between tool invocations.
This patch moves `InitLLVM` ownership into `opt.cpp`:
```text
standalone opt:
main -> InitLLVM -> optMain -> shutdown
embedded host:
host-owned InitLLVM / LLVMToolSession -> optMain
```
Standalone opt therefore keeps the same lifetime and behaviour, while
LLVMOptDriver can borrow the lifetime owned by an embedding application.
This patch is independent of the proposed `LLVMToolSession `and
`LLVMLlcDriver` changes that I've proposed in the RFC and can be
reviewed separately.

[OpenMP] Give the device shared memory allocations a debug location. (#221842)
Fixes https://github.com/llvm/llvm-project/issues/221831.
In generic mode on the device, the buffers that carry values into an
outlined region come from device shared memory rather than the stack, so
they are emitted as calls to `__kmpc_alloc_shared` and
`__kmpc_free_shared`. Those are definitions in the DeviceRTL, which
makes them inlinable calls, and the verifier requires an inlinable call
in a function with debug info to carry a !dbg location. None of these
calls had one, for two separate reasons.
1. `allocateVar()` and `deallocateVar()` took a bare insertion point, so
an override had no debug location to set on the runtime calls it emits
in place of the alloca the base class would have created. Fixed by
adding a `DebugLoc` parameter that carries one.
2. The `createOMPAllocShared `and `createOMPFreeShared` calls in
`createParallel` relied on the implicit conversion from an insertion
point to a `LocationDescription`, which selects the constructor that
leaves the debug location empty, and `updateToLocation` then installs
that empty location over whatever the builder had. Fixed by passing the
`Builder`, which carries the debug location along with the insertion
point. This is the same fix as #218961.

[JITLink][RISCV] Avoid quadratic removal of alignment edges (#222317)
We encountered this issue while using BOLT to instrument clang on
RISC-V. JITLink spent significant time removing alignment edges during
relaxation finalization in large code blocks with many alignment
relocations.
During RISC-V relaxation finalization, finalizeBlockRelax removes
AlignRelaxable edges individually from a block's edge vector. Each erase
shifts the remaining suffix, making this cleanup quadratic when the
number of alignment edges grows with the total edge count.
Compact surviving edges once and remove the trailing entries from the
back, preserving edge order and making cleanup linear. Count the
trailing entries before erasing to avoid comparing an invalidated
iterator.
These results support the performance benefit, but they come from
**GPT-generated** synthetic benchmarks and do not represent speedups on
real BOLT workloads.

[flang] add AllocationPolicy attribute to module and use it in InlineHLFIRCopy (#222013)
The StackArrays/AllocationPlacement pass cannot move fir.allocmem
created during InlineHLFIRCopy for the copy-in/cop-out buffers because
of there placement in branches.
Moving these allocmem outside of the branches is suboptimal as these
allocations may never occur at runtime (when the data is actually
already contiguous).
Extending the StackArrays pass is doable but very tedious (the data flow
analysis passes used in the pass cannot recognized "same
predicates"/understand that the two fir.if block that
allocate/deallocates will be both reached or never reached (even when
modifying InlineHLFIRCopy to use the same SSA value for both fir.if). So
this requires custom logic, and was adding 200 lines of non trivial code
to audit and I did not like it.
I decided to expose the allocation policy so that other passes can rely
on it. To make it the most flexible and future proof this is done via a
new module attribute instead of threading options in the driver to this
and that pass. This way, it will also be possible to have custom per
function policy if ever needed.
The InlineHLFIRCopy is updated to apply the small array threshold policy
(that decide when constant size arrays should always be placed on the
stack, regardless of the -fstack-array/-fno-stack-array). I also
increased this threshold from 64 to 1024 so that it cover my application
use case. This increase is in line with the industry practice (NV, IFX,
and gfortran will all allocate few Kb temporary copy-in/out buffers on
the stack, regardless of the optimization level). For now, I decided to
not apply the `-fstack-array` aspect as it is on by default with flang
and I want to measure the effect first before doing so (gfortran/ifx
also control dynamic copy-in/out buffer allocations with the stack-array
related flag, so there is a good chance we end-up doing it at some
point).

[mlir][vector] Fix mask neutral value for masked fmaximum/fminimum reductions (#222275)
Masked maximumf/minimumf reductions were lowered by replacing inactive
lanes with a neutral value before applying an unmasked reduction. The
maximumf neutral was incorrectly set to the negative subnormal closest
to zero, causing it to beat any negative active value. Similarly,
minimumf used FLT_MAX, which loses to an active +Inf.
This change adds LLVM dialect support for
llvm.vp.reduce.fmaximum/fminimum and lowers masked reductions directly
to these predicated intrinsics.

[libc] Optimize the GPU printf implementation with size hints (#222474)
Summary:
The GPU printf interface is functionally a shim to pass a `va_list` and
format string to the CPU for formatting. The size of the argument list
isn't exposed by the C ABI, but we can use `__builtin_object_size` to
try to look it up. This will bind to the `alloca` holding our arguments
in the ABI and return a positive size if it is known.
We do this opportunistically, as the check is lossy. In cases where it
is known, this saves a stack spill to store the true size. Additionally,
we can use this to detect cases where `printf` is being used as a simple
`puts`.
This saves 10 VGPRs for the `printf("string")` case. It also saves 8
bytes of stack in most all cases.

[clang][CodeGen] Stop overriding GlobalVariable's default address space (#222367)
The `GlobalVariable` constructor used by `createGlobal` receives a
`std::optional<unsigned> AddressSpace` that, when unspecified, falls
back to `M.getDataLayout().getDefaultGlobalsAddressSpace()`. However,
`createGlobal`'s `AddressSpace` arg was a bare `unsigned` defaulting to
0. By doing that, it was effectively overriding the `GlobalVariable`'s
constructor fallback with 0. On targets whose default globals address
space is not 0 (AMDGPU, SPIR/SPIR-V), this emitted
`@llvm.global_ctors/dtors` in address space 0 causing some issues (see
https://github.com/ROCm/SPIRV-LLVM-Translator/issues/293).

[AArch64] Reorder ZPR stack spills to maximize ld1b/st1b pairings (#218950)
Currently, the stack allocation algorithm can order spilled ZPR
callee-saves in a way that prevents pairing.
Reorder ZPR callee-saves before frame indices are assigned to maximize
pairing opportunities. Pairing requires consecutive even/odd registers
at even stack offsets.
The remaining legality requirements are already checked when the
register pairs are formed.
The reordering algorithm primarily works by determining the parity of
the lowest ZPR spill offset. If the offset is odd, it places one
unpaired ZPR spill first so that subsequent register pairs begin at even
offsets.
Windows is not supported by this reordering algorithm for now, to keep
this change minimal.
New tests have been added to sve-callee-save-restore-pairs.ll to test
the reordering algorithm.

The current check in `emitLabel()` is too strict. Inside a PR, there

which are used e.g. for calculating offsets can be emitted. A situation
in which this occurs is the emission of the DWARF EH tables, in which a
temporary symbol (with an empty name) is emitted at the begin of the
table, causing an error message. This change limits the error to
non-temporary labels.

I plan to remove the DIA PDB plugin before the 24 release - we switched
the default to the native one in 22. To avoid losing test coverage in
the process, this moves the SymbolFile/PDB tests to
SymbolFile/NativePDB. They were already running with both plugins. In
some cases, we set `env LLDB_USE_NATIVE_PDB_READER=1`, which I flipped.
The remaining shell tests are:
- `func-symbols.test`: Has a duplicate in NativePDB with different
checks, because the two plugins don't create identical types (see
comment in test)
- `udt-layout.test`: Also has a duplicate with different checks, because
the two plugins show the base classes in a different order.
Other than that, there's also a [unittest for
PDB](https://github.com/llvm/llvm-project/blob/2de38b4861ed4a7be7ddd42fc803e91d1fe81b14/lldb/unittests/SymbolFile/PDB/SymbolFilePDBTests.cpp).
I'm not sure what we should do about it. Looking over the tests there,
most of these are already covered by the shell tests.

[Hexagon] Lower vreduce(min|max)((imum)?) (#211898)
Add custom lowering for VECREDUCE_FMIN/FMAX/FMINIMUM/FMAXIMUM on HVX
float vector types. The target-independent default expansion reduces
these pairwise using the hardware min/max instruction directly, which
does not implement IEEE-754 NaN-propagation semantics: a NaN in the
input can silently corrupt the reduction result, and an all-NaN input
produces a non-NaN value instead of NaN.
The custom lowering strips NaN elements to the appropriate neutral value
(+/-Inf) before the pairwise tree reduction so a NaN can't corrupt other
lanes, then fixes up the scalar result to NaN if every input element was
NaN.
FMINNUM/FMAXNUM on HVX vector types get the same treatment: NaN operands
are replaced with the neutral value before delegating to the hardware
min/max, with a fixup to restore NaN when both operands were NaN (per
llvm.minnum/maxnum semantics).

[llvm-ar][GOFF] Implement symbol attributes for GOFF archives (#214528)
z/OS archive symbol table entries contain a 32-bit attribute word
alongside each member offset.
The low three bits encode:
```
bit 2 (0x4): 64-bit addressing (AMODE 64)
bit 1 (0x2): XPLink calling convention
bit 0 (0x1): Writable Static Area (WSA)
```
Previously in e2c8fa0, llvm-ar wrote zero for these attributes. This
patch reads them from GOFF ESD
records and stores them in a SymbolAttrs vector parallel to the existing
Symbols vector in MemberData
to emit the correct word per symbol.
These attributes are tested using `llvm-nm --print-armap` implemented in
#214527 within the LIT test.

[SystemZ][z/OS] Fix "relative immediate relocation section mismatch" (#222437)
Constants should go inside the text section, but this is not explicitly
coded. In the test case, the EH table is generated into a PR section.
Then the constant pool of function `fn_with_const_pool()` is emitted,
which goes into the PR section of the EH table instead of the code
section. When the constant is later referenced in the code, the relative
offset cannot be calculated because different sections are involved.
The fix is to explicitly return the text section for constants.

[CodeView] Read and dump `S_ASSOCIATION` (#221034)
`S_ASSOCIATION` associates one symbol with another one. Right now, it's
only used for coroutines. The `get_associatedSymbol*` functions from
[`IDiaSymbol8`](https://learn.microsoft.com/en-us/visualstudio/debugger/debug-interface-access/idiasymbol8)
use this record. I'm not sure if the VS debugger uses this at all.
The symbol value was added earlier, but we weren't able to read/write
it. Also, lld would remove it when linking, as it didn't know if it
contained type indices.
This PR adds support for that. It's only visible in llvm-pdbutil where
we can dump it and roundtrip through yaml. I checked that it uses the
correct format when used with the DIA dump sample.
The coroutine kind is still missing. It's contained in the flags of an
`S_FRAMEPROC`. But it'd like to wait for #215887 which touches the flags
in YAML.

represents a contiguous 4-element chain.
- `copysign_combine_v4f16` and `canonicalize_combine_v4f16` now
vectorize identically on `GFX8` and `GFX9`.
- Adding `canonicalize_combine_v4f16_noncontiguous`, to preserve
existing test coverage, so the non-contiguous-gather path isn't silently
dropped.

[AMDGPU] Enable CSE in the GlobalISel post-legalizer combiner (#217258)
Enable GISel CSE in the legacy AMDGPU post-legalizer combiner so it
matches the new pass-manager path.
Use the standard CSE configuration for the optimization level. Create
correctly constrained virtual registers during legalization instead of
mutating register classes after creation, and notify GlobalISel
observers when register operands are replaced. This also updates the
affected GlobalISel checks.

Further, it moves the classification of valid shader stages into a
common table to denote where a semantic is interpreted and how it is
used to to derive if it is valid.
This also updates tests that were using invalid semantic constructs to
use corrected versions.

[MLIR][XeGPU] Lower arith.truncf wider than one xevm.truncf group (#217130)
`xevm.truncf` lowers to device builtins that convert exactly 16 f16/bf16
elements
per call, so `TruncfToXeVMPattern` only matched a 16-element source. A
workgroup-level mxfp GEMM that quantizes A in the kernel produces a
wider one,
which nothing else lowers, so the module failed to build:
%r = arith.truncf %a : vector<32xbf16> to vector<32xf4E2M1FN>
// cannot be converted to LLVM IR: missing
`LLVMTranslationDialectInterface`
// registration ... for op: arith.truncf
Convert a whole number of groups at a time instead: slice the source
into
16-element groups, emit one `xevm.truncf` per group, and concatenate the
packed
results before the final bitcast. A source of exactly one group takes
the original
path with unchanged code, and a source that is not a whole number of
groups is
still left to the regular arith-to-LLVM path.
`arith.extf` carries the same restriction on its result, but no wider
case has come
up, so it is left as is.

[mlir-translate] Add structured translation entry point (#222623)
Please read: [RFC: Embeddable LLVM tool drivers for long-lived
hosts](https://discourse.llvm.org/t/rfc-embeddable-llvm-tool-drivers-for-long-lived-hosts/91754)
and the [MLIR
section](https://discourse.llvm.org/t/rfc-embeddable-llvm-tool-drivers-for-long-lived-hosts/91754#p-367966-mlir-13).
`mlir-opt` already separates its standalone command-line frontend from
its reusable implementation:
```text
command-line parsing
↓
MlirOptMainConfig
↓
MlirOptMain(input buffer, output stream, registry, config)
```
`mlir-translate` currently combines those responsibilities inside
`mlirTranslateMain(int argc, char **argv, ...)`: it registers and parses
its command-line options, opens the input and output files, and then
performs the translations.
This patch applies the existing mlir-opt structure to mlir-translate. It
extracts the MLIR translation executor behind a structured overload
accepting an input buffer, output stream, selected Translation objects
and an MlirTranslateMainConfig. The existing command-line entry point
continues to parse the same options and delegates to the new overload,
so its command-line behaviour remains unchanged.
Separating parsing from execution is useful for any application
embedding MLIR. Such an application already has its input, output and
selected translation, and should not be required to install another
command-line frontend into the process merely to call MLIRTranslateLib.
[WasmBolt](https://github.com/anutosh491/WasmBolt)(try
[here](https://anutosh21.github.io/WasmBolt/)) is one concrete consumer.
It runs `mlir-opt`, `opt`, `llc`, Clang and LLD inside one long-lived
browser-hosted LLVM process. Calling the complete `mlir-opt` and
`mlir-translate` command-line frontends in that process causes common
options such as `-o` to be registered twice in LLVM's process-global
command-line registry.
```
mlir-translate: CommandLine Error: Option 'o' registered more than once!
LLVM ERROR: inconsistency in registered CommandLine options
```
The structured entry point allows WasmBolt to invoke the actual MLIR
translation operation without registering another command-line frontend.
This is needed to continue naturally from the MLIR LLVM dialect to LLVM
IR inside the same compiler session.
Add a simple test where the test register its own `-o` option first,
then runs two translations through the new API and checks the output.
This confirms that the translation path works without touching the
command-line parser. **Can Improve it a bit if it looks too informal.**

Extended LIBC_ENABLE_COVERAGE to support LLVM_LIBC_FULL_BUILD=ON and

This enables developers and CI pipelines to measure source-level and
MC/DC coverage directly on hermetic tests in full-build configurations
without relying on the host C library.
Updated add_libc_hermetic in LLVMLibCTestRules.cmake to link hermetic
tests with -noprofilelib, -u__llvm_profile_runtime, and compiler-rt's
profiling library. Replaced internal entrypoint objects in
link_object_files with public entrypoint objects for the C functions
referenced by libclang_rt.profile.a.
Added calloc and __errno_location to HermeticTestUtils.cpp to satisfy
remaining freestanding profiling runtime dependencies. Updated
libc/docs/dev/code_coverage.md with full-build instructions.

[lldb] Expose vector registers through SBValue (#220707)
This is adding GDB remote vector register support.
- Build exact Clang types from parsed vector metadata.
- Use native Clang vectors where valid and arrays where required to
preserve exact layouts.
- Support nested, pointer, boolean, and non-power-of-two vectors.
- Expose vector lanes through `SBValue` children and expression paths.
- Handle typed vector data correctly across target byte orders.
- Add builder, SB API, layout, cache, and big-endian tests.
Example:
```
vector = frame.FindRegister("v0")
vector.GetNumChildren() # 4
vector.GetChildAtIndex(2).GetValue() # "3.5"
vector.GetValueForExpressionPath("[2]").GetValue() # "3.5"
v = frame.FindRegister("v0")
print([v.GetChildAtIndex(i).GetValue()
for i in range(v.GetNumChildren())])
# ['1.5', '2.5', '3.5', '4.5']
```
Structured `register read` output is added separately in patch 5.

[clang] Support DecompositionDecl in -ast-print (#221711)
`DeclPrinter` had no `VisitDecompositionDecl`, so `auto [a, b] = get();`
printed as `auto = get();`, silently dropping the binding list (worse
at namespace scope, where it also produced a stray empty statement per
binding).
Add `DeclPrinter::VisitDecompositionDecl`, printing the full
`type [bindings] = init;` form for all three decomposition kinds
(aggregate/member, array, tuple-like), matching what `VisitVarDecl` does
for an ordinary declaration. Specifier and initializer printing is
shared between the two via two helpers (`printVarDeclSpecifiers`,
`printVarInitializer`) so they can't drift apart.
Each binding prints correctly, including a pack's leading `...` and
per-binding attributes. `BindingDecls` are skipped when walking a
`DeclContext` directly, since each is already printed as part of its
`DecompositionDecl;` a decomposition declaration is likewise kept out of
the tag-declaration grouping in `VisitDeclContext`, which would
otherwise merge it into a preceding `struct S { ... } obj;`.

[compiler-rt] Handle weak interfaces with MinGW GCC (#222706)
Windows weak-function emulation uses MSVC linker /alternatename
directives, which GNU ld does not support. Use direct exported
definitions, avoid registering unsupported DLL weak aliases, and
reference UBSan's real C++ implementation.

[CMake] Don't reference unexported targets from dependency-only configs (#222630)
#221724 stopped exporting a project's targets file when that project is
enabled only as another project's dependency, but the build-tree
`ClangConfig.cmake` and `MLIRConfig.cmake` still include it
unconditionally. `find_package()` therefore finds the config and fails
inside it:
```
CMake Error at build/lib/cmake/clang/ClangConfig.cmake:19 (include):
include could not find requested file:
build/lib/cmake/clang/ClangTargets.cmake
Call Stack (most recent call first):
CMakeLists.txt:90 (find_package)
```
This breaks any configuration that enables Flang without also enabling
Clang or MLIR explicitly: `runtimes/CMakeLists.txt` calls
`find_package(Clang ...)`, which is deliberately not `REQUIRED` and is
expected to tolerate an unavailable package — but a *half-generated*
package is a hard error rather than a "not found". Concretely,
`-DLLVM_ENABLE_PROJECTS=flang -DLLVM_ENABLE_RUNTIMES=flang-rt` fails at
`runtimes-configure`, which is the configuration premerge uses for
flang-rt changes.
This patch guards the include the same way the export itself is guarded,
so a dependency-only project generates a config without a dangling
include. The install-tree path already handles this through
`get_config_exports_includes()`; only the build-tree path was missed.
MLIR has the same defect and is fixed here too. It is currently latent
only because `runtimes/CMakeLists.txt` calls `find_package(Clang)` and
not `find_package(MLIR)`; a `find_package(MLIR)` against a
dependency-only build tree fails identically at `MLIRConfig.cmake:33`.

[TOSA] Add pass to sanitize gather/scatter indices (#221200)
Add new TosaGatherScatterHardeningPass TOSA pass to clamp indices before
they are fed to a tosa.gather or tosa.scatter unless a suitable clamp
sequence already exists. This enables avoiding out-of-bounds accesses on
untrusted indices in tosa.gather and tosa.scatter lowering.
The pass fails if the dimension indexed by the indices tensor of any of
the tosa.gather or tosa.scatter is dynamic. The pass supports EXT-INT64
by using the same element type in the clamp min/max sequence as the
indices tensor. In case the indexed dimension is bigger than can be
represented in the element type bitwidth the maximum value in that
bitwidth is used.

-----------
[LoopIdiom] Recognize the ctlz/cttz idiom when the input is known non-zero (#222373)
LoopIdiomRecognize converts a shift-until-zero loop to `ctlz`/`cttz`.
When the loop uses the count outside the loop, it needs a zero check of
the input before the loop. Without the check, the inputs 0 and 1 give
the same count. The recognizer stops when the check is not present.
The check is not necessary when the input is known non-zero. InstCombine
can remove the check for such inputs. Then the recognizer does not
convert the loop. This happens in `sbc_calc_scalefactors` from ffmpeg
with #222334: the input is an or reduction that starts at 32768, so it
is never zero, and the loop stays a loop.
This patch makes the recognizer accept a known non-zero input in place
of the zero check. The conversion is exact in this case.
`ctlz-loop.ll` in PhaseOrdering had a FIXME for a loop over `abs(n)`.
The recognizer now converts that loop too.
For the ffmpeg case, `isKnownNonZero` must also see that an or
recurrence with a non-zero start is non-zero. That change goes into
#222334.

[TSan][Darwin][Test-only] Fix crash in write-interpose.c test (#222656)
Due to this test running with verbosity turned up, an early 'Report'
happened to get caught by the test's write interceptor, and on newer
macOS versions the interceptor's call to printf was attempting to
allocate before the allocator was initialized - leading to a crash.
This patch instead uses snprintf to a stack allocated buffer in order to
avoid allocating in the interceptor.

[RISCV][P-ext] Add packed multiply-parts accumulate intrinsics (#222571)
Support the RISC-V P packed multiply-parts accumulate instructions, which
add selected products into `rd`.
The intrinsics lower to dedicated `PMACC_HALVES_*` SelectionDAG nodes
rather than an `add` of plain products, ensuring instruction selection
does not depend on DAGCombine folding. On RV32, the word forms
accumulate into a GPR pair via new `WMACC`, `WMACCU`, and `WMACCSU`
nodes.
Also add corresponding Clang builtins and wrappers in
`riscv_packed_simd.h`.

[VPlan] Use VPlan-based costs for scalarized FP inductions. (#222442)
Continue the migration of induction costs to be VPlan-based by dropping
the legacy fallback in precomputeCosts for FP inductions. Widened FP
inductions were already costed by VPWidenIntOrFpInductionRecipe; the
missing piece is the scalarized form. Extend both VPDerivedIVRecipe and
VPScalarIVStepsRecipe to support FP inductions.
This also removes WidenedIVs, which becomes dead: it is only ever filled
from VPWidenIntOrFpInductionRecipe, and the legacy path now only sees
pointer inductions.
The new cost numbers should be more accurate, taking into account the
int->fp conversion cost, plus FMul and FAdds we generate.
Checking if FAdd/FMul can be folded requires a few additional checks (in
particluar the FAdd requires -0.0 to fold, FMul needs 1.0,
https://alive2.llvm.org/ce/z/g_khUS). Currently we do not yet carry
fast-math flags on the VPDerivedIVRecipes, so those are not considered
for now. The difference should be negligable in practice.

Compute vector bit widths from the rank-one MLIR dimension and saturate

Add regression coverage for both vector.insert and vector.extract.

[libc] Fix Darwin aarch64 fenv and sigsetjmp build support (#192079)
This patch fixes Darwin aarch64 build failures in libc around fenv and
sigsetjmp support.
Before this change, the Darwin aarch64 fenv implementation did not match
the public fenv_t layout and referenced several Darwin-specific
exception/control bits that were not defined in llvm-libc. This caused
libc builds to fail in fenv_darwin_impl.h with a sizeof(fenv_t) vs.
internal-state mismatch and multiple undeclared-identifier errors for
FE_FLUSHTOZERO and the FPCR trap/flush bits.
This patch fixes that by updating the internal Darwin aarch64
floating-point state layout to match fenv_t, defining the missing Darwin
FPCR bit values used by the implementation, and handling the
flush-to-zero exception bit consistently.
The patch also fixes the Darwin sigsetjmp path by enabling sigjmp_buf
support on Apple targets, adding the Darwin signal pieces needed by that
path (sigaddset, sigdelset, sigemptyset, sigfillset, sigprocmask, plus
Darwin signal macros), and updating the aarch64 sigsetjmp inline
assembly to branch through a local label before jumping to setjmp,
avoiding an assembler error from using cbz with an external symbol
target.

Expose the Arith dialect, attributes, and interfaces without importing

users avoid parsing the operation umbrella and its dependencies.
Across three controlled serial rebuilds of five dialect-only TUs, median
instructions fell from 49.429B to 39.665B (-19.755%) and wall time fell
from 7.40s to 5.85s (-20.946%). Across three -j16 rebuilds of 97 support

wall time fell from 29.17s to 28.07s (-3.771%).

[libc] Add sys/file.h and flock function. (#222737)
`flock` is a BSD function that manages advisory locks on opened files
(see https://man7.org/linux/man-pages/man2/flock.2.html)
It has enough differences from `fcntl`-based locking mechanism, and is
provided and used on Linux platforms.
* Add `<sys/file.h>` public header on Linux platforms with `flock`
declaration
and proper macro used for `op` function argument.
* Provide a Linux implementation, which is a simple syscall wrapper
around
`SYS_flock` syscall.

[mlir][Tosa] Optimize compliance initialization for size to improve build time (NFC) (#222791)
The compliance-map constructor includes a 4,920-line generated
initializer. Mark it minsize because it runs only when creating the
validation pass and optimizing this single large function at -O3 is
expensive.
LLVM pass timing attributes most of the saving to code generation.
Greedy register allocation fell from 7.070s to 1.348s as global
live-range splitting fell from 6.403s to 0.021s after the constructor
became 47.6% smaller.
Across five controlled rebuilds of the affected TU, median instructions
fell from 205.087B to 66.157B (-67.742%) and median wall time fell from
19.83s to 7.95s (-59.909%).

The AArch64 target info class in the ABI library is still a work in
progress. It will continue to report "not yet implemented" for function
signatures involving SVE types. This change is a neceasary prerequisite
for correctly handling them or correctly deferring handling of these
specific types.

[lld][MachO] Add `--warn-missing-subsections-via-symbols` flag (#221464)
This change introduces:

file with non-empty sections is missing `MH_SUBSECTIONS_VIA_SYMBOLS`.
* `--no-warn-missing-subsections-via-symbols`: Disables the warning
(default).
Also adds documentation and lit tests.
Object files missing `MH_SUBSECTIONS_VIA_SYMBOLS` can prevent
dead-stripping and subsection splitting.
We have seen a number of cases where we are compiling assembly, and this
allows us to track them down.

[lldb][Darwin] Don't mark threads as having hit bp if not (#222488)
When a multithreaded program stops exeuction with a mach exception on
more than one thread, if one of the threads is *at* a breakpoint site,
but hasn't *hit* the breakpoint yet, lldb was incorrectly stepping over
the breakpoint instruction when it resumed execution. This would result
in TestConcurrentManyBreakpoints reporting that a breakpoint hit on 100
threads was only hit 99 times, because one of the breakpoints was
silently stepped past without being counted.
The bug happened because on Darwin/debugserver systems the stop info
packet includes a `jstopinfo` which is a JSON dictionary of all threads
that have an exception. When `jstopinfo` is present, ProcessGDBRemote
was initializing any thread not included in `jstopinfo` as having an
empty StopInfo. It did this without checking if we are _at_ a breakpoint
site, and marking the thread as "Stopped at unexecuted breakpoint
instruction". Because the threads now had an empty StopInfo already, the
other places where we might check "if stopped at unexecuted breakpoint
instruction" were never executed.
I created a gdb_remote_client API test with a synthetic test case where
four threads stop at a breakpoint; three of them have hit the
breakpoint, one has not. And confirm that lldb only registers 3
breakpoint hits initially, and then the 4th as we resume. Debugging the
"99 breakpoints hit instead of 100" failures was tricky and involved
running the test in a loop on a heavily loaded machine to get the
necessary timing, and it was easy to give up, so I wanted a much simpler
synthetic case to show the problem if we might regress.

[flang] Fold fir.convert of an integer constant between integer types (#222188)
`fir::ConvertOp::fold` doesn't handle an integer constant converted to
another integer type. `ForwardConstantConvertPattern` covers the
neighboring case where the result is `index`, so `fir.convert %c10_i32 :
(i32) -> index` already canonicalizes to an index constant while
`fir.convert %c1_i32 : (i32) -> i64` does not. This PR adds the
integer-to-integer case.
The width change follows the rules codegen applies to a non-constant
operand (`CodeGen.cpp`'s integer-to-integer conversion): narrowing
truncates, widening zero-extends an i1 or unsigned source and
sign-extends anything else. The result must be signless because the
constant materialises as an `arith.constant`, which only accepts
signless integers.
It composes with `arith::IndexCastOp::fold`, so a value widened then
cast to `index` collapses to one index constant, and it lets other
patterns see through the constant: with a literal shift,
`simplify-hlfir-intrinsics` can now fold away `hlfir.eoshift`'s
shift-direction arithmetic.
`getIntIfConstant` only matches `arith` and `llvm` constants, which are
signless, so `isUnsignedInteger()` is never true today, but I still kept
the unsigned case anyway so that the fold cannot disagree with codegen.

[LoopInterchange] Supported partially-perfect Loop Nests (#199511)
In the current implementation when the outermost loop contains sibling
sub-loops (i.e. multiple independent loop nests at the same depth), the
pass silently skips the entire loop nest without attempting to
interchange any of the valid sub-nests (See Below Example).
Example:
```
for(int i=0; i<n; i++){ // Loop 1
for(int j=0; j<m; j++){ // Loop 2
for(int r=0; r<m; r++){ // Loop 3
// Do something
}
}
for(int k=0; k<p; k++){ // Loop 4
for(int l=0; l<p; l++){ // Loop 5
//Access A[l][k]
}
}
}
```
In the Example , GCC 16 performs loop interchange on (Loop2, Loop3) or
(Loop4, Loop5), provided the interchange is both legal and profitable.

[Flang][OpenMP] Remove target implicit allocatable member mapping from MapInfoFinalization and extend lowering to support it (#219434)
This PR aims to remove the partially implemented implicit allocatable
member mapping code from MapInfoFinalization, and move it to the
lowering.
The MapInfoFinalization code should no longer be required as the
DeclareMapper infrastructure in the frontend is capable of handling
these cases now and already does so for the majority of them, so we are
better consolidating the implementation to one location and extending it
to support more cases.
This PR removes the old code from MapInfoFinalization, and enables the
default declare mapper generation that handles most other implicit
mapping cases for derived types in the initial lowering to handle the
previously supported cases and more.
The implicit default declare mapper generation has been modified to only
map the necessary bits of a derived type, which are record types (to
hold any nested mappers and to make sure we map all non-allocatable
bits, including descriptors) and the data for any allocatable bits
(specifically just the ref_ptee and then an attach emission).

Add a machine-level pass to remove redundant DBARs and merge them with
atomic memory operations. The pass uses machine dominator and
post-dominator trees to ensure the transformation is safe across basic
blocks.

When converted to int a bool value is either `0` or `1`, but the `enum_value`

Make bool enums take the unsigned value code path so that `0` or `+1` is

Instead of relying on the middle-end to clean it up, improve the

[MLIR][Parser] Fix precision loss when parsing f80 and f128 literals (#220267)
While analyzing this CIR issue
[216422](https://github.com/llvm/llvm-project/issues/216422), I traced
the issue to the MLIR asm parser.
For the following case:
```
%0 = arith.constant 1.0E+309 : f80
```
using `mlir-opt repro.mlir`
we get (infinity):
```
module {
%cst = arith.constant 0x7FFF8000000000000000 : f80
}
```
instead of
```
module {
%cst = arith.constant 9.99999999999999999986E+308 : f80
}
```
Currently the parser casts floats to a double before converting to the
requested semantics, as noted in the
[comments](https://github.com/llvm/llvm-project/blob/bb3b509138f4a34cb3d5c659955ccc16745ae82e/mlir/lib/AsmParser/AsmParserImpl.h#L286).
Not entirely sure why this was the default, anyway this patch instead
parses the float with the given semantics directly, so we don't lose
precision.
I used Claude to generate tests and reproducers for this patch. I've
also updated a few existing lit tests to show the improved precision
this patch introduces.
**Note:** This fixes the CIR issue I mentioned above.

[LiveDebugValues] Do not join debug values whose operand counts disagree (#221929)
Currently, `DbgValueProperties::isJoinable()` decides whether two values
could be joined by comparing their `DIExpressions` only. That was safe
when location-operand count was taken from the expression. In
instruction-referencing `LiveDebugValues`, `NumLocOps` is taken from the
`MachineInstr` (`getNumDebugOperands()`), so two values can share an
expression and still differ in operand count.
Joining pairs location operands by index. When the counts disagreed,
`pickVPHILoc` indexed past the shorter list and hit `assert(Index <
OpCount)` in `DbgValue::getDbgOpID`.
This change makes `isJoinable()` return `false` unless `NumLocOps`
**also agrees**.

veto (hasShorterEVEXViaCDisp8), kept in sync only by a comment. Hoist it
into X86II::isDispOrCDisp8 in X86BaseInfo.h (ImmOffset now optional) and
call it from both, so the size model cannot drift from what the encoder
emits. No functional change.

[ConstraintElim] Strengthen flags at the closest dominator of all uses. (#220918)
Flags are currently only strengthened using the facts that hold on entry
to the block defining the instruction. This overly pessimistic. It is
sufficient to check at the closest instruction dominating all uses.
Extend FactOrCheck to carry this point as context instruction (in union
with the mutually exclusive DoesHold to avoid size growth) and retrieve
the common dominating instruction when queuing instructions for flag
strengthening.
This strengthens flag inference in a number of real-world cases, as well
as enables additional folds due stronger flags:

[RISCV] Ignore debug instructions in epilogue block checks (#219401)
A debug instruction in a return-only block can make
`RISCVFrameLowering::canUseAsEpilogue` reject an otherwise valid
shrink-wrap
point. This moves the save and restore libcalls onto the fast path.
Ignore debug instructions in the successor cardinality check while
continuing
to count bundle interiors, pseudo probes, and other non-debug
instructions.
The first commit records the existing behavior. The second applies the
fix and
updates the test expectations to require localized save and restore
calls.
Fixes #219378
Testing:
- Verified that the regression test fails on an affected compiler.
- Verified the targeted test after the fix.
- RISC-V CodeGen: 2654/2654 passed.

There were a few issues here:
- Names that are not templates were not diagnosed and led to a crash (in
part because clang think they can be template names that will be later
resolved by ADL)
- Names that refer to a variable template decl, etc also led to a crash.

[lldb] Fix handling of lldb managed software breakpoints (#222009)
Fixes #217910.
When the debug server can manage its own breakpoints this is called an
"external" breakpoint. When it cannot, lldb must manage the breakpoint
itself from the client side.
Part of doing that is FindInRange which is used to patch reads and
writes over software breakpoint sites. It had an issue where it would
not account for a breakpoint that started before the range, but extended
into the range. For example:
```
Memory content: ABCDEFGHIJKL
Read range: ----[--]----
Breakpoint location: -BKPT-------
Overlap with read: ---- at -------
Expected read result: ----EFGH----
Would actually get: ----TFGH----
```
This change fixes that mistake:
* Exit early if there are no sites to check.
* Exit early if the lower_bound result is beyond the upper bound of the
range - only if the result is not the end of the list. In the result was
end(), there may be one site before which we must also check.
The existing "Over end of breakpoint" test covers the bug I'm fixing.
The tests have been refactored to run normally and via. a proxy that
refuses breakpoint packets.
We could instead use two different proxies where one supports the
packets and one doesn't. However, that's more overhead per test and you
can't run proxy tests remotely.
Due to https://github.com/llvm/llvm-project/issues/222284, the proxy
tests cannot be run everywhere, but it can run on AArch64 which is
common.

[AArch64] Parameterize repeated FP divisor combine threshold by subtarget (#216930)
Changes:
This patch makes the threshold for combining repeated FP divisors
configurable per AArch64 subtarget, instead of using a single fixed
value 3 for all CPUs. Additionaly, set this value 2 for A64FX based on
observed profitability for this transform on A64FX.
Motivation:
Today, AArch64 uses a fixed threshold of 3 for reciprocal transform.
This means the transform runs when there are 3 FDIVs with the same
divisor (not 2). That is conservative for some subtargets, and it can
miss profitable opportunities on CPUs such as A64FX, where a lower
threshold appears to produce better code generation.
```
a / D; b / D; ...
=>
recip = 1.0 / D; a * recip; b * recip; ...
```
Note:
It does not change the semantics of the reciprocal transform itself.

[MLIR] Fix infinite loop in tryFold in Graph Regions (#189232)
In a graph region (e.g. the module body), an op may use its own result
as an operand, creating a circular SSA dependency. When such an op was
passed to OpBuilder::tryFold, the do-while loop could spin forever:
1. foldCommutative moved the constant operand to the RHS (in-place fold,
foldResults still empty).
2. The next fold call returned the op's own result, signalling an
in-place fold, but foldSingleResultHook re-ran trait folds, found
nothing to swap, and returned success with empty foldResults.
3. Step 2 repeated without end.
Fix: cap the number of in-place fold iterations at 64. Legitimate chains
are very short in practice (foldCommutative swaps once, then the op folds to
a value or constant), so the cap is never reached for correct IR. For the
circular-SSA case the loop now terminates and tryFold returns failure,
letting dialect conversion fall through to a conversion pattern instead of
looping.
An alternative could be for each iteration of the loop, snapshot the
operand list and attributes/properties. If a fold returns empty results
but the operands are unchanged, we have reached a fixpoint. Stop the
loop and return failure.
However this is more expensive for the common case, while fixing an edge
case.

[flang][OpenACC] Don't emit unstructured-loop TODO for wrappable loops (#222260)
`genOpenACCLoopFromDoConstruct` raised an NYI for any unstructured DO
inside `acc kernels`. That check ran before the wrapping in
`genFIR(DoConstruct)`, so a loop whose CFG is self-contained aborted
lowering even though the fall-back path would have wrapped it in an
`scf.execute_region`.
Skip the TODO when `isWrappableConstruct()` accepts the loop. Such a
loop is not attached to a directive; it is only nested inside the
kernels region.
Correspondingly, a DO loop sitting directly in an `acc kernels` body is
no longer wrappable, since it is the loop the directive parallelizes and
hiding its CFG would leave the kernels region with nothing to partition.

[libc] Implement pthread_attr_[gs]etschedpolicy (#222682)
This patch implements pthread_attr_setschedpolicy and
pthread_attr_getschedpolicy.
This commit only operates on the pthread_attr_t object. It does not
attempt to install the scheduling policy when creating a new thread. I'm
leaving that for a separate patch as it requires a moderately
complicated startup dance to ensure that the scheduling policy takes
effect before the startup code runs.
The validation of inputs in pthread_attr_setschedpolicy is an
interesting question. Glibc accepts only policies explicitly declared in
POSIX, while other implementations let the user pass anything, and rely
on the kernel to validate the arguments. Interestingly, even glibc does
not validate the arguments in pthread_setschedparam.
For llvm-libc, I chose not to validate the arguments either. This is
*mostly* consistent with POSIX, which says (emphasis mine):
> The supported values of policy shall *include* SCHED_FIFO, SCHED_RR,
and
> SCHED_OTHER, which are defined in the <sched.h> header.
I say mostly, because the spec does say we should return ENOTSUP if "an
attempt was made to set the attribute to an unsupported value", but I'm
not sure that's worthwhile, as it means we would need to update our list
of supported policies whenever the kernel adds a new one (and anyway, we
cannot be sure that our understanding of supported policies matches what
the running kernel actually supports).

[SLP] Limit second pass to register VF in vectorizeNonVectorizableInsts. (#222755)
The second tryToVectorizeList pass in vectorizeNonVectorizableInsts
would try all roots for each possible VF between 1 and the number of
entries in the list.
This can cause super-linear compile-time, for example when there are
basic blocks with calls taking a large number of loads as arguments.
For example, running SLPVectorizer on a block with 1024 loads passed to
calls (https://llvm.godbolt.org/z/8M53G6WzW) will take a large amount of
time (timeout on godbolt, locally on Apple M1 it takes ~30s). With the
fix, it only takes 0.01s.
On large IR corpus, I did not see any difference in vectorization
decisions on AArch64.

Before: When estimating edge weights within `computeEdgeWeights` in

`1 / (GraphT::child_end(BB)_ - GraphT::child_begin(BB))` resulting in
integer division and incorrect distribution of estimated edge weights.
After: Correctly estimate edge weights with zero and non-zero values of
`TotalChildrenCount` by enforcing floating point division.

[OMPIRBuilder] Don't leak a foreign debug loc into the taskwait call (#222586)
A kmp_depend_info array is hoisted to the entry block of the enclosing
function. Pointing the builder into that block also adopts the location
of what is already there, which belongs to whichever construct put it
there rather than to the construct being emitted. restoreIP does not put
the location back either, since it adopts the location of the
instruction it lands on, so in createTaskwait the leak outlives the
excursion and reaches the __kmpc_omp_taskwait_deps_51 call.
Use InsertPointGuard, which restores the location along with the
insertion point.

We never make use of the fact that these functions are `constexpr`, so
we might as well avoid complicating them for it. Even if we need them to
be `constexpr` at some point, we likely won't require them to be
`constexpr` in C++11, which is the only language mode with the single
statement restriction that caused this to be more complicated.

tryToRecognizeTableBasedCttzOrLog2 accepted any global that isConstant()

change at run time -- it does not mean the initializer that is read is
the one that gets linked. An interposable (weak/linkonce) constant, or
an externally_initialized constant, can be replaced with a different
constant table at link or load time, so folding tbl[i] against the
observed initializer is unsound for those.

[lldb] Validate universal Mach-O slice bounds before parsing (#221493)
Opening a corrupt universal (fat) Mach-O file can crash lldb. A fat-arch
header entry's (offset, size) pair is untrusted, and `GetObjectFile()`
passes it straight to `ObjectFile::FindPlugin()` with no check against
the
container's own size.
A slice whose offset is 0 points back at the start of the same fat
header,
so `GetObjectFile()` recurses into itself until the stack is exhausted:
```
$ ./ObjectContainerTests --gtest_filter=GetObjectFileSelfReferentialSlice
#230 ObjectContainerUniversalMachO::GetObjectFile(FileSpec const*) ObjectContainerUniversalMachO.cpp:188
#231 CreateObjectFromContainer(...) ObjectFile.cpp:43
#232 lldb_private::ObjectFile::FindPlugin(...) ObjectFile.cpp:146
#233 ObjectContainerUniversalMachO::GetObjectFile(FileSpec const*) ObjectContainerUniversalMachO.cpp:188
(repeats until the stack is exhausted)
SUMMARY: AddressSanitizer: stack-overflow (libsystem_trace.dylib:arm64e+0x16bd8) in os_log_fmt_flatten+0x6d4
```
A slice whose declared size is far larger than the file reaches the
allocator instead, with the untrusted size unchanged:
```
$ ./ObjectContainerTests --gtest_filter=GetObjectFileOversizedSlice
==89958==ERROR: AddressSanitizer: requested allocation size 0xffffffffffff0046
(0xffffffffffff1048 after adjustments for alignment, red zones etc.) exceeds
maximum supported size of 0x10000000000 (thread T0)

SUMMARY: AddressSanitizer: allocation-size-too-big MemoryBuffer.cpp:343 in
llvm::WritableMemoryBuffer::getNewUninitMemBuffer(unsigned long, llvm::Twine const&, std::__1::optional<llvm::Align>)
```
`GetModuleSpecifications()` in the same file already guards its own
recursion this way: it only follows a slice that starts strictly past
the
container's current offset, and clamps the recursive call to the bytes
remaining in the container. Apply the same check to `GetObjectFile()`.
Found with lldb-target-fuzzer. The commands above are the two regression
tests added here.

[libc++][test] Remove non-functional `constexpr` in three-way comparison test for `variant` (#222837)
When we are just testing SFINAE and do not provide definitions for these
comparison operators, or make them deleted, it is unhelpful to mark them
`constexpr`.
If the implementation uses `std::compare_three_way`, which uses deduced
return type in its `operator()`, in the `operator<=>` for `variant`,
more things in the function body would be instantiated and detected. As
a result, the `-Wundefined-inline` warning or something similar could be
raised. Currently, MSVC STL is doing so.

[libc] Implement pthread_kill (#222625)
The implementation delegates to Thread::kill, which uses tgkill to
target the thread ID.
The main complication is handling zombie threads. POSIX.1-2024 requires
that pthread_kill on a terminated (zombie) thread does not return ESRCH
because the pthread_t handle is still valid. The Linux kernel reaps
threads immediately on exit, so calling tgkill on an exited thread would
return ESRCH (or worse, target a recycled TID). To handle this:
- we check the thread's detach_state first. If it's already EXITING, we
simply return success without calling tgkill (a zombie thread cannot
handle signals anyway).
- if the thread exits concurrently and tgkill returns -ESRCH, we assume
it transitioned to a zombie and treat it as success.
I've also added a tgkill syscall wrapper and replaced one raw usage of
SYS_tgkill.
I've added an integration test covering signal delivery to self and
other threads, signal 0 checks, invalid signals, zombie threads, and
signal mask interactions.

[KnownFPClass] Move `fadd`/`fsub` tests to `nofpclass-fadd-fsub.ll` (#221872)
- Moved the lit tests for `fadd`/`fsub` to their own dedicated file.
- Updated the lit tests for `fadd`/`fsub` from version 2 to version 6.
- `fadd_p0_ftz_daz #3` was actually testing `positivezero|positivezero`,
so I fixed the name of the test to be `fadd_p0_ftpz_dapz #3`. Then added
a separate `fadd_p0_ftz_daz #0` test.
- `nofpclass-fadd-fsub.ll` uses attributes 1-9 except for 6, so I added
`fadd_p0_dynamic_dynamic #6` so I wouldn't have to change the attributes
for other tests (i.e. changing `test #7 --> test #6`, `test #8 --> test
#7`, etc)
The only tests for `fadd` that remain in `nofpclass.ll` are not related
to testing `KnownFPClass::fadd`.
I have split the PR into 3 commits to make it easier to review (4
commits due to the `undef` false positive).
After this PR lands I plan to open this PR

[clang][OpenMP] Don't drop debug location when handing off to OMPIRBuilder. (#219548)
All the clang callsites that hand a `LocationDescription` to the
`OpenMPIRBuilder` pass `CGF.Builder`. That selects
`LocationDescription(const IRBuilderBase &)`, which carries both the
insertion point and the current debug location.
The 2 call sites fixed in this PR used `CGF.Builder.saveIP()` which
passes only an insertion point, selecting `LocationDescription(const
InsertPointTy &)`, which leaves `DL` empty. As a result, the IR the
builder emitted on clang's behalf came out without `!dbg`.
Fixed by passing `CGF.Builder`, as the other callsites do.

`tensor.insert_slice` where the dropped unit dim is:
1. leading, e.g., `dest = 1x8x4, source = ?x4`,
2. trailing, e.g., `dest = 8x4x1, source = ?x4`, and

[OpenMP] Rename ClauseSet to Clauses and DirectiveSet to Directives, NFC (#222440)
The ClauseSet name was an alias of an EnumSet of clause ids. However, it
collides with a "clause set" concept in OpenMP, which is a set of
clauses,
but with properties and additional information. To resolve the naming
conflict, rename ClauseSet to Clauses.
Although there is no "directive set" in OpenMP, rename DirectiveSet in
an analogous way for uniformity.

[MLIR][Conversion] Remove func dialect dependency for CF to SCF conversion (#222594)
The pass used to target only `func.func` and generates a `func.return`
with poison values. Now we change it to `ub.unreachable`, as the TODO
suggests.
But this change alone can cause the following pattern to appear after
lifting:
```mlir
func.func @f(%arg0: f32, %arg1: i1) -> f32 {
cf.cond_br %arg1, ^bb1(%arg0 : f32), ^bb2
^bb1(%0: f32): // pred: ^bb0
ub.unreachable
^bb2: // pred: ^bb0
return %arg0 : f32
}
```
This `cf.cond_br` cannot be raised further into `scf.if`, because we
need something as the operand of `return`, while `ub.unreachable`
doesn't provide this. Therefore we reused the code of synthesizing
poison values when `ub.unreachable` can be merged to other return
operations.

[InferAlignment] Do not use intrinsic align attributes as base pointer alignment (#221018)
InferAlignment propagates alignment between accesses of the same base
pointer: each load/store records how aligned the base must be, and later
accesses of that base are upgraded. Since #156057 (masked.load/store)
and
#217172 (memcpy/memmove/memset), the align parameter attribute of these
intrinsics is fed into the same table.
That is not sound. A memset with a zero length (or a masked store with
an
all-false mask) does not access memory, and its pointer argument is
allowed
to be poison, so an align attribute on it proves nothing about the
pointer.
For
```llvm
define void @test(ptr %p, i64 %n) {
call void @llvm.memset(ptr align 16 %p, i8 0, i64 %n, i1 false)
store i32 0, ptr %p
ret void
}
```
the store was upgraded to align 16, which is UB when %p is only 4-byte
aligned and %n is 0.
Stop presenting the attribute alignment to the base pointer logic: the
intrinsic branch now passes align 1, the same convention the
and(ptrtoint)/trunc(ptrtoint) patterns use for "this instruction proves
nothing". The attribute can still be improved from a dominating real
access or from known bits. A constant non-zero length would be a
provable access, but it is deliberately not special-cased, as suggested
in the issue.
Fixes #220520

For `E1.E2()` and `E1->E2()`,
1. A `MemberExpr` is created to represent `E1.E2` and `E1->E2`.
If overload resolution is performed, it is created using information
from a `UnresolvedMemberExpr`.
2. If `E2` is an explicit object member function, a `DeclRefExpr` is
created to represent `E2` using information from the `MemberExpr`.
This PR adds missed information to the `DeclRefExpr`.
Fixes #218829.

[clang][bytecode] Use opaque pointers for decl-based dummy pointer (#222897)
This uses the recently introduced opaque pointers for what we used to
use dummy pointers for, if the base of the pointer is a declaration.
This of course means we see opaque pointers in a lot more places.
However, we don't need to actually allocate anything for their data
anymore, resulting in a lot fewer allocations for such pointers.

[dyndbg][LLD][ELF] Initial LLD support for dynamic debugging (#214188)
LLVM's Dynamic Debugging feature (`llvm/docs/DynamicDebugging.md`)
generates optimized relocatable files with an unoptimized relocatable
copy of the functions from its translation unit embedded in a
`SHT_LLVM_DYNDBG_ELF` section named `.debug_llvm_dyndbg`. The
unoptimized functions in the "inner" embedded relocatable reference the
functions and data of the "outer" optimized relocatable.
When LLD encounters dynamic debugging objects, a nested "inner"
relocatable link is run with the embedded "inner" unoptimized objects.
The output is embedded in a `SHT_LLVM_DYNDBG_ELF` section named
`.debug_llvm_dyndbg` and described by an `NT_LLVM_DYNAMIC_DEBUGGING`
note in the "outer" output. The "inner" relocatable link more closely
resembles a final link rather than a regular relocatable `-r` one,
unless the "outer" link is itself a relocatable `-r` link.
The embedded "inner" objects' undefined symbols are added to the "outer"
symbol table so that the "outer" link resolves the dependencies of the
"inner" relocatable link. Symbols referenced by "inner" relocations from
an allocated section are assigned a PLT/GOT entry as appropriate and are
diagnosed when unresolved. In this initial implementation, these symbols
also act as `--gc-sections` roots for the "outer" link and
`--gc-sections` is not supported for the "inner" relocatable link.
ICF is disabled so that individual functions can be patched when
debugging with dynamic debugging without affecting other identical
functions.

[OpenMP] Don't reserve the generic mode warp on SPIR-V (#222763)
#218790 widened a generic mode kernel's thread bound by a warp so that
the main
thread has one of its own. The bound is what lets the runtime's own warp
addition through: `getEffectiveNumThreads()` adds a warp and then clamps
to the
bound, so before that change the addition was clamped straight back off,
which
is why a `thread_limit` below one wavefront ended up with no workers.
Widening
the bound is the fix, and it is also what makes every generic mode
kernel launch
a warp wider than it used to.
`hasGridValue()` covers SPIR-V, so that geometry change reached Level
Zero.
@sarnex reports hangs and intermittent failures there and asked about a
revert
in
https://github.com/llvm/llvm-project/pull/222097#issuecomment-5609354538.
The
motivating bug was on AMDGPU, so this restricts the reservation to the
targets
it was written for and gives SPIR-V back the launch geometry it had
before.
Measured on gfx90a, generic mode, threads per block for a given
`thread_limit`:
| `thread_limit` | launched |
| --- | --- |
| 1 | 65 |
| 4 | 68 |
| 64 | 128 |
| 256 | 320 |
| 1024 | 1024 (clamped) |
Before #218790 each of those launched exactly `thread_limit`, because
the clamp
removed the runtime's warp again. SPIR-V goes back to that with this
patch:
`thread_limit(4)` writes a bound of 4 rather than 68, while AMDGPU keeps
68.
I have not reproduced the Level Zero failures — I have no Intel device,
and
OpenMP offload to `spirv64-amd-amdhsa` is not a working path, so AMD
hardware
cannot stand in. What this patch does establish is that SPIR-V's bound
returns
to its pre-#218790 value, so it undoes the geometry change whether or
not that
is the whole story. @sarnex, could you try it on the Level Zero runner?
This is a narrowing rather than a claim that SPIR-V never wants the
reserved
warp. Without it a SPIR-V `thread_limit` below a warp has the same
no-workers
problem #218790 fixed elsewhere; it is just not reachable today. If
Level Zero
grows the handling, this can come back.
Testing: `clang/test/OpenMP` 1613 passed,
`llvm/test/Transforms/{OpenMP,Attributor}`
263 passed, `LLVMFrontendTests` 1322 passed. Two tests needed updating,
both of
which encode SPIR-V thread bounds.

[AMDGPU] Remove the VGPR-alignment check from the machine verifier (#219230)
The machine verifier had a check that a 64-bit-or-wider VALU operand uses an even-aligned VGPR/AGPR tuple on subtargets that require it. Now that most operands express their alignment requirement through `_AlignTarget`, the check is redundant: the generic verifier already rejects a register that does not fit its operand's class.
This removes the "Subtarget requires even aligned vector registers" and "Operand has incorrect register class" diagnostics, leaving the generic "Illegal virtual/physical register for instruction".
The image `vaddr` parity check is left in place: single-VGPR alignment cannot be expressed as a register class, so it still needs an explicit check.

[clang][APINotes] Do not drop attributes applied after a definition (#222902)
API notes are matched against whichever declaration the compiler
reaches, which can be a redeclaration that follows the definition. When
the definition lives in one module and the annotated redeclaration in
another, that is exactly what happens: checkNewAttributesAfterDef()
warns "attribute declaration must precede definition" and erases the
attribute, so the annotation is silently lost.
The warning exists to tell users that an attribute they wrote has no
effect. Attributes from API notes are not written in the source, so the
warning has nowhere to point and there is nothing for the user to
correct. Skip attributes with an invalid location, alongside the
existing exceptions.

[X86] Fix i64-to-bf16 conversion crash on 32-bit targets (#222934)
Converting a loaded `i64` to `bfloat` can crash instruction selection on
i686:
```llvm
define bfloat @convert(ptr %p) {
%value = load i64, ptr %p
%result = sitofp i64 %value to bfloat
ret bfloat %result
}
```
With `llc -mtriple=i686-linux-gnu`, this hits:
```text
Do not know how to custom type legalize this operation!
```
The X86 DAG combine folds the load and conversion into an x87 `FILD`
node
before type legalization. It already excludes `f16` and `f128`, but was
missing
`bf16`, leaving the legalizer with an unsupported result type.
Add `bf16` to that exclusion. This lets the existing legalization
promote the
conversion through `f32` and then round to bf16. The change also covers
the
constrained signed conversion, which uses the same combine.

[lldb][Windows] Make RM_RF actually delete files (#222950)
On Windows `RM_RF` was `rd /s /q`, which only removes directories — so
any `$(call RM_RF,...)` naming files silently did nothing, and `|| (exit
0)` hid it. POSIX gets `rm -rf`, which removes both.
`clean::` recipes pass file globs and usually run before the build
(`all: clean ...`), so stale artifacts survived into the next run. Hits
upstream `functionalities/disassembler-variables` too.
Fix adds `del /f /q`, joined with `&` not `&&` so `rd` still runs when
the glob matched no files.

[SPIRV] Emit NonSemantic DebugDeclare, DebugExpression and DebugOperation (#222011)
Add support for
[DebugDeclare](https://github.khronos.org/SPIRV-Registry/nonsemantic/NonSemantic.Shader.DebugInfo.html#DebugDeclare),
[DebugExpression](https://github.khronos.org/SPIRV-Registry/nonsemantic/NonSemantic.Shader.DebugInfo.html#DebugExpression)
and
[DebugOperation](https://github.khronos.org/SPIRV-Registry/nonsemantic/NonSemantic.Shader.DebugInfo.html#DebugOperation).
Changes:
- Emit DebugDeclare from an indirect DBG_VALUE whose location register
is defined by OpVariable, which is what the spec requires of the
Variable operand. LLVM IR `#dbg_declare` does not survive as its own
opcode in MIR, `IRTranslator` [lowers
it](https://github.com/llvm/llvm-project/blob/06d0711313b763b65c7e4a9e8613893d7760b6f6/llvm/lib/CodeGen/GlobalISel/IRTranslator.cpp#L4592-L4596)
to an indirect DBG_VALUE.
- DebugDeclare has a `Indexes` operand that didn't find necessary to
implement. The SPIRV-LLVM Translator has no support for it either in
both modes (ir <-> spv).
- The following cases are unhandled to avoid emitting invalid code (see
below comment about spirv-val):
- an access chain into a field
([debug-declare-access-chain.ll](https://github.com/llvm/llvm-project/blob/users/mgcarrasco/nsdi-debug-declare-new/llvm/test/CodeGen/SPIRV/debug-info/debug-declare-access-chain.ll))
- an OpFunctionParameter for a byval argument
([debug-declare-function-parameter.ll](https://github.com/llvm/llvm-project/blob/users/mgcarrasco/nsdi-debug-declare-new/llvm/test/CodeGen/SPIRV/debug-info/debug-declare-function-parameter.ll))
- a constant address
([debug-declare-int-storage.ll](https://github.com/llvm/llvm-project/blob/users/mgcarrasco/nsdi-debug-declare-new/llvm/test/CodeGen/SPIRV/debug-info/debug-declare-int-storage.ll))
- a register left without a def after dead storage was erased
([debug-declare-dead-alloca.ll](https://github.com/llvm/llvm-project/blob/users/mgcarrasco/nsdi-debug-declare-new/llvm/test/CodeGen/SPIRV/debug-info/debug-declare-dead-alloca.ll))
- a variadic #dbg_value
([debug-declare-dbg-value-variadic.ll](https://github.com/llvm/llvm-project/blob/users/mgcarrasco/nsdi-debug-declare-new/llvm/test/CodeGen/SPIRV/debug-info/debug-declare-dbg-value-variadic.ll))
- an expression using an unmapped operation
([debug-declare-expression-unsupported.ll](https://github.com/llvm/llvm-project/blob/users/mgcarrasco/nsdi-debug-declare-new/llvm/test/CodeGen/SPIRV/debug-info/debug-declare-expression-unsupported.ll))
- a variable whose DebugLocalVariable was not emitted
([debug-declare-skip-type.ll](https://github.com/llvm/llvm-project/blob/users/mgcarrasco/nsdi-debug-declare-new/llvm/test/CodeGen/SPIRV/debug-info/debug-declare-skip-type.ll))
- Collect expressions from MIR, so DebugExpression and DebugOperation
are emitted at module scope and shared by every declare using the same
DIExpression.
- Map the nine operations the instruction set defines, and reject an
expression whole when an argument does not fit in 32 bits (as per spec).
- Cache DebugLocalVariable result ids, which emitDebugLocalVariable
already returned but nothing stored.
- Add tests for each emitted and skipped case, for the interaction with
DebugLine and DebugScope, and for the expression operations.
spirv-val and the spec disagree in two places, in opposite directions:
- DebugDeclare's Variable operand: spirv-val accepts an
OpFunctionParameter, while the spec names only OpVariable. This patch
follows the spec, so the byval case is skipped even though spirv-val
would take it, see
[debug-declare-function-parameter.ll](https://github.com/llvm/llvm-project/blob/users/mgcarrasco/nsdi-debug-declare-new/llvm/test/CodeGen/SPIRV/debug-info/debug-declare-function-parameter.ll).
- DebugGlobalVariable's Variable operand: spirv-val rejects a
DebugExpression there although the spec permits one,
KhronosGroup/SPIRV-Tools#6469, see
[debug-global-variable-constant-value.ll](https://github.com/llvm/llvm-project/blob/users/mgcarrasco/nsdi-debug-declare-new/llvm/test/CodeGen/SPIRV/debug-info/debug-global-variable-constant-value.ll).

Add StackFrame.compileUnitId, an id that names the frame's compile unit
within the module already reported as StackFrame.moduleId. Clients
resolve it through the compileUnits request, which now reports the same
id on each CompileUnit and takes an optional compileUnitIds filter to
ask for individual compile units instead of the module's full list.
CompileUnitsRequestHandler declared its arguments optional but
dereferenced them unconditionally, so a compileUnits request carrying no
arguments crashed the adapter. Drop the optional and let the request
framework reject the request instead.

This patch implements pthread_attr_getscope and pthread_attr_setscope.
Same as other libraries, we only support the system contention scope
(PTHREAD_SCOPE_SYSTEM). Process contention scope (PTHREAD_SCOPE_PROCESS)
is not supported, and would basically require a userspace N:M threading
implementation. Since this value cannot be checked in the kernel, I
reject it directly during the attribute set operation, and don't even
bother storing it in the attribute object.

[lldb][debugserver][NFC] Share the expedited-memory type and emitters (#222911)
Expedited memory had two representations:
- The frame pointer backchain used `StackMemory`, a fixed
`uint8_t[2 * sizeof(nub_addr_t)]` plus a length, held in a `std::map`
keyed
by frame address.
- Frame 0's window used `ExpeditedMemory`, which owns a
`std::vector<uint8_t>`.
Three call sites then open-coded the same emit loop, twice into a JSON
array
and once into a stop reply.
Keep `ExpeditedMemory` for both and emit through
`AppendExpeditedMemoryToJSON`
and `AppendExpeditedMemoryToStopReply`. `ReadFrameZeroStackMemory`'s
local
`read_range` lambda becomes `AppendExpeditedMemory`. `ReadStackMemory`
keeps
its own read, because it needs the bytes to continue the walk.
`ReadStackMemory` gains an explicit `visited` set. It previously relied
on its
`std::map` to stop a corrupt frame pointer chain that loops back on
itself, by
testing whether the key was already present. A `std::vector` has no such
test,
so the guard becomes explicit. This keeps the existing behavior rather
than
changing it.
Chunk count and chunk sizes are unchanged. Backchain chunks now go out
in
frame-walk order rather than ascending frame address; the bytes for a
given
address are the same either way, so the cache the client builds is
unchanged.
This prepares for expediting the another memory read range, which have
arbitrary address and length. `StackMemory`'s fixed buffer cannot hold a
range
of a few hundred bytes, and appending and emitting one costs three lines
with
these functions in place rather than a fourth copy of the emit loop.

[LLVMABI] Handle Atomic types in the LLVM ABI library (#221367)
The LLVM ABI library's type system had no way to represent atomic types,
so Clang's QualTypeMapper was just mapping them directly to the
underlying value type. This resulted in mis-classification of some
function signatures involving atomic types.
This change adds AtomicType to the ABI type system and QualTypeMapper.
The actual classification didn't require any updates. Simply having the
atomic type as a distinct type was sufficient for it to produce the
expected results.

[SandboxVec][Scheduler] Update full state of scheduler when IR changes (#222180)
Up until now the scheduler state has not been maintained fully upon IR
changes.
This is not really needed for correct operation of the current
vectorizer because scheduling happens before emitting the vectorized IR,
so there is no real need for updating the scheduler with the current
implementation. Nevertheless, the implementation may change so the right
thing to do is to make sure the scheduler's state is always correct.
So this patch implements the missing callbacks for erase, move and set
use and updates the scheduler state accordingly.

[clangd] Add missing SymbolKind cases to YAML serialization (#222070)
The YAML index writer maps index::SymbolKind to strings through a list
of enumCase calls that was not updated when Concept, IncludeDirective,
and the template parameter kinds were added to the enum. Writing a
symbol with one of these kinds matches no case, so nothing is emitted
for the value and the next key lands on the same line, producing Kind:
Lang: C. With assertions enabled, the writer aborts rather than emitting
malformed YAML. This affects clangd-indexer --format=yaml when indexing
C++20 concepts.
Add the missing cases so the list mirrors the enum, drop the duplicate
Function entry, and add a test that round-trips every current SymbolKind
through YAML. The binary index format stores the kind as a raw byte and
is unaffected.

[Clang] Refactor instantiation of declarations within concepts (#221707)
After implementation of CWG2369, declarations are instantiated on demand
when evaluating a concept.
This was hinged on TemplateInstantiator, where we intercepted most calls
that need an instantiated declaration. This is almost identity to
SetupConstraintScope, which tries to re-instantiate any declarations to
the current scope. This patch removes SetupConstraintScope because we
can instantiate anything on demand.
The concept normalization patch brings us more troubles when we have to
deal with sugars: declarations instantiated outside of the scope (e.g. a
typedef declaration) are never added/instantiated during instantiation
of concepts: this patch makes that function also look up outer scopes
for those declarations. Note that we couldn't simply make the scope of
concepts 'transparent', since we don't want clashes of instantiated
function parameters.
Also also this added a call to instantiateMissingDeclsToScopeForConcepts
for C++26 fold expressions, before checking any pack sizes.

[CostModel][X86] Add variable divisor div/rem costs for scalar and <=i32 vectors (#215124)
Div and rem by a variable divisor have no X86 cost entry at all, so they
fall through to the BasicTTI default and cost 1. A 20 to 40 cycle
unpipelined instruction ends up priced the same as an add.
That mattered less while vector integer division always scalarized,
since the price was wrong but the decision was usually right anyway.
After #205263 the <=i32 shapes lower through a float divide, so the
vector cost model is now describing a sequence that really exists and it
still prices it as scalarization.
This adds scalar entries plus five feature gated vector tables.
Numbers are the maximum llvm-mca Block RThroughput across the CPUs that
fold the shape with the low power lines excluded (atom and jaguar).
Vector entries take the max within the tier a CPU's feature level
selects, since the lookup takes the first matching table. Scalar takes
it across all of them.
rem is priced the same as div because a variable rem is the same
instruction and the hardware hands back the remainder in rdx or AH. For
vector the fold pays a multiply and subtract to recover it but the
divide dominates the throughput so the number doesnt change.
div-rem-strictfp.ll is new and pins the strictfp gate. Two SLP tests run
on forced negative thresholds and needed those raised so both produce
output identical to before at the new value.

[WebAssembly] Select relaxed_trunc for vector fptosi/fptoui with +relaxed-simd (#214148)
Fixes #211273
When `+relaxed-simd` is enabled, plain vector `fptosi`/`fptoui` from `<4
x float>` to `<4 x i32>` is still lowered to
`i32x4.trunc_sat_f32x4_{s,u}`. The relaxed SIMD instructions already
exist in the backend, but they were only wired to the
WebAssembly-specific `llvm.wasm.relaxed.trunc.*` intrinsics—not to
generic `fptosi`/`fptoui` IR.
This matters for frontends like LDC that emit ordinary `fptosi` for SIMD
casts (e.g. `_mm_cvttps_epi32`-style code). With
`+simd128,+relaxed-simd`, we should prefer
`i32x4.relaxed_trunc_f32x4_{s,u}`, which typically lowers more
efficiently
on native SIMD hardware.
The fix adds two TableGen selection patterns in
`WebAssemblyInstrSIMD.td`, gated on `HasRelaxedSIMD` with
`AddedComplexity = 1`, so they win over the existing
`fp_to_sint`/`fp_to_uint` → `trunc_sat` patterns when relaxed SIMD is
available.
This does not require fast-math: for representable inputs, relaxed
truncation matches LLVM semantics; for NaN/out-of-range inputs,
`fptosi`/`fptoui` already produce poison, so the backend is not required
to preserve `trunc_sat`'s
saturating behavior.
Explicit saturating conversions (`llvm.fptosi.sat` / `fp_to_sint_sat`)
and `+simd128`-only targets are unchanged.

[SLP]Treat 2-element FP reductions as always associative
A reduction of exactly 2 elements is a single operation, so no
reassociation is possible and the associativity check is not needed.
Emit vector.reduce.fadd/fmul with the reassoc flag for such
reductions even when the scalar operation lacks it, instead of
2 extracts + scalar operation.

[libc] Write LF line endings from cmake_format.py on every platform (#222742)
I ran the libc CMake formatter on Windows and it gave back a file whose
every line had changed:
```
$ printf 'add_library(foo STATIC\n a.c\n)\n' > CMakeLists.txt
$ python libc/utils/cmake_format.py -i CMakeLists.txt
Formatted CMakeLists.txt
$ python -c "print(open('CMakeLists.txt','rb').read())"
b'add_library(foo STATIC\r\n a.c\r\n)\r\n'
```
`format_cmake_content()` joins its lines with `"\n"`, but
`process_file()` hands that string to `open(temp_file, "w",
encoding="utf-8")`, and a text-mode write substitutes the platform line
separator. So on Windows, reformatting one command in a file rewrites
the endings of the whole file. `.gitattributes` declares no `text`/`eol`
rules and `llvm/docs/GettingStarted.md` tells people to clone with
`core.autocrlf=false`, so nothing normalizes those endings back before
the commit.
The read side already normalizes: `open(..., "r")` gives universal
newlines, so a CRLF file is LF by the time the formatter sees it.
Passing `newline="\n"` on the write makes both ends agree and gives the
same bytes on every platform.
The same substitution applies to stdout, which affects the piped output
and the `--diff` text (a CRLF diff does not apply against an LF file),
so I configured stdout the same way in `main()`.
One behaviour change worth flagging: on Windows, a CMake file that
currently has CRLF endings and needs reformatting now comes out with LF
rather than CRLF. Files that are already formatted are not written at
all, before or after, since the comparison is made on the LF-normalized
read.
For the tests, everything in `cmake_format_test.py` today asserts on the
string returned by `format_cmake_content()`, so nothing covers what
lands on disk. I added two cases that compare the bytes on disk and on
stdout against that string. They fail on Windows before this change (the
assertion prints `b'...\r\n...' != b'...\n...'`) and pass after; on
Linux and macOS they pass either way, since the separator is already LF.
The file went from 47 to 49 tests, all passing under `python -m unittest
cmake_format_test`.
I did not have `black` available on that machine, so the added code
follows the surrounding style by hand rather than by running the
formatter.

[clang][CodeGen] Emit lifetime markers for block-scoped compound literals in C (#219045)
In C (C99/C11/C23 §6.2.4.5), block-scoped compound literals have
automatic storage duration extending to the end of the enclosing block
scope. Previously, Clang emitted alloca storage without lifetime
markers (@llvm.lifetime.start / @llvm.lifetime.end), preventing LLVM's
StackColoring pass from merging stack slots across disjoint scopes and
inflating stack frame size.
Following John McCall's guidance in #68746:
1. In Sema, record block-scoped compound literals in ExprCleanupObjects
so
the enclosing full-expression is wrapped in an ExprWithCleanups.
2. In CodeGen, emit @llvm.lifetime.start before evaluating initializers
and
schedule CallLifetimeEnd as a cleanup.
Checking a build of an x86_64 Linux kernel defconfig build, this shaves
448 bytes off the stack usage for azx_probe(), one of the larger stack
users in the kernel.

[SPIRV] Refactor implicit binding legalization (#222848)
This change rewrites the `SPIRVLegalizeImplicitBinding` pass so that
binding collection is driven by intrinsic declarations rather than a
full-module instruction walk.
Previously, the pass used an `InstVisitor` to visit every instruction in
the module and find calls to a small set of intrinsics. The new
implementation iterates over the intrinsic declarations and their users,
making the cost proportional to the number of relevant resource calls
rather than the size of the module.
There is no change to the SPIR-V emitted for existing shaders. Implicit
bindings are still assigned the same numbers.
Other improvements include:
- Order IDs are extracted once into a `SmallVector` instead of being
recomputed on each sort comparisons.
- The separate `verifyUniqueOrderIdPerResource` walk is folded into the
binding assignment loop.
- Make helpers that replace implicit binding calls static.
- Added a `HasImplicitBinding` flag for early exit and accurate
`Changed` reporting, so a module with no implicit bindings (or with a
declaration that has no users) now returns `PreservedAnalyses::all()`
instead of unconditionally invalidating analyses.

riscv64 doesn't have a legal i32 type in the backend, but we
support i16, and i32 loads/stores. AArch64 also supports i16
loads/stores even though i16 isn't legal.
Replace TTI.isTypeLegal with DL.fitsInLegalInteger and a check for
a power of 2 number of bytes. This covers i16 and i32 for RISC-V
and i16 for AArch64.
We could further relax this to cover types that the backend can handle
by splitting, but I'd like to leave that for a future patch.
I had to update some existing tests to have more accurate datalayouts.
The RISC-V tests are reduced from existing tests from AArch64 or X86 to
show some of the load sizes that can now be matched.

[RISCV][SLP] Use common alignment when checking constant-stride loads (#222520)
Fix SLP's constant-stride load legality check, which can widen naturally
aligned 32-bit loads into misaligned 64-bit RVV accesses and cause
`SIGBUS`.
In `BoUpSLP::canVectorizeLoads`, the check uses the first sorted load's
alignment, which may be stronger than that of later widened groups. Pass
`CommonAlignment` to `analyzeConstantStrideCandidate` instead, matching
the existing cost model and code generation. This is conservative: it
fixes the legality check without deriving a more precise alignment for
each widened group's starting address, so it may reject some otherwise
legal widening.
### Reproducer
The following reproduces the failure on the tested [SpacemiT K1 / Banana
Pi F3](https://docs.banana-pi.org/en/BPI-F3/BananaPi_BPI-F3) running
RV64 Linux, compiled with `-O3 -march=rv64gcv -mabi=lp64d
-mstrict-align`:
```c
struct Row {
unsigned x, y, padding[5];
};
_Static_assert(sizeof(unsigned) == 4, "requires 32-bit unsigned");
_Static_assert(sizeof(struct Row) == 28, "requires a 28-byte row");
__attribute__((noinline))
void gather_fields(const struct Row *p, unsigned *restrict out) {
p = __builtin_assume_aligned(p, 16);
out[0] = p[0].x + 3;
out[1] = p[0].y + 3;
out[2] = p[1].x + 3;
out[3] = p[1].y + 3;
}
int main(void) {
_Alignas(16) struct Row rows[2] = {
{5, 9, {0}}, {11, 17, {0}}};
unsigned out[4];
gather_fields(rows, out);
return out[0] != 8 || out[1] != 12 ||
out[2] != 14 || out[3] != 20;
}
```
The alignment assumption is satisfied, and the four loads at byte
offsets `0`, `4`, `28`, and `32` are naturally aligned and in bounds.
SLP widens the adjacent pairs into:
```llvm
%v = call <2 x i64> @llvm.experimental.vp.strided.load.v2i64.p0.i64(
ptr align 4 %p, i64 28, <2 x i1> splat (i1 true), i32 2)
```
On RV64 this lowers to:
```asm
li a2, 28
vsetivli zero, 2, e64, m1, ta, ma
vlse64.v v8, (a0), a2
```
whose second active lane accesses `base + 28`, which is not eight-byte
aligned. The legality check incorrectly uses alignment 16, although the
emitted intrinsic already carries `align 4`.
On the tested machine, the example raises `SIGBUS` before the fix and
returns zero afterward. The fixed compiler uses 32-bit vector loads and
retains vectorized arithmetic.

[CIR] Emit classic's attributes for a non-byval indirect argument (#222445)
CallConvLowering marked an indirect argument that is not byval with
llvm.byref. Classic gives this argument llvm.nofreeobj, llvm.noundef,
llvm.align, and llvm.dereferenceable instead.
A call site forwarding such a parameter used to identify it by reading
llvm.byref back, so the pass now records the parameter where the
signature rewrite creates it. The "byref" vocabulary is removed, since
it no longer names anything CIR emits.

[Clang][Sema] Report diagnostic for invalid mask in shufflevector (#221558)
Clang used to accept a vector with an integer representation as a valid
mask; otherwise, it reported a type mismatch. This led to accepting a
vector of booleans as a valid mask and reporting that types are not
equal if both arguments are equal but not vectors of integers.
Currently, it checks for the mask type and reports a clear error message
if the mask is a vector of bool or not a vector of integers

Introduction of Composite Profile section in ExtBinary format (#166553)
New sections are introduced for storing profile of vairous types:
* SecCompositeProfile (like SecLBRProfile but can conain multi-type
profile)
* SecCompositeFuncOffsetTable (like SecFuncOffsetTable but offsets point
to SecCompositeProfile)
The only change in the structure of ExtBinary is a substitution of
SecLBRProfile and SecFuncOffsetTable sections by new (composite) ones,
so, to void duplication of layout description and handling, all changes
are done on low-level: section types are modified in the existing layout
right before profile writing.
No new profile types are introduced - this change is rather a
preparation for future profiling extentions: only LBR profile can be
inside currently.
Processing of VTable profile is unmodified.
Extended description is here:
https://discourse.llvm.org/t/rfc-typifiedprofilesection-generalized-per-function-profile-blocks-in-extbinary-format/87881
Testing of the new scenario is added to
llvm/test/tools/llvm-profdata/sample-flatten-profile.test and also new
tests are introduced.

[libc][CPP] Add vector container and unit tests (#222972)
Sequential group database entrypoints require dynamically resizable

Rather than managing raw heap reallocations manually within subsystem
parsers, dynamic growth is encapsulated in a dedicated cpp::vector
container.
Add cpp::vector in libc/src/__support/CPP/vector.h with move semantics,
safe fallible allocation (returning bool for out-of-memory handling
without C++ exceptions), and RAII clean-up for trivially and
non-trivially destructible types.

[OpenMPOpt] Ask the runtime how many of a block's threads can be workers (#221450)
The custom state machine gates a thread on `InitCB < BlockHwSize -
WarpSize`,
reconstructing the worker count from the block size on the assumption
that the
main thread occupies a whole warp above them. That arithmetic has to be
kept in
step with whatever launch geometry the toolchain uses, and when it is
not, the
workers in between are left in neither group, waiting for no parallel
region
while the runtime hands them iterations.
Export the number the device runtime already computes in
`mapping::getMaxTeamThreads()`, which its own generic state machine
gates on, as
`__kmpc_get_max_team_threads()`, and gate on that instead. The new entry
point is
added to the virtual-use callback that keeps the state machine's callees
alive,
and the existing `runtimeFnsAvailable()` check skips the rewrite against
an older
device runtime.
NFC upstream, where `getMaxTeamThreads()` is `BlockSize - WarpSize`. It
matters
for a toolchain whose block is not laid out that way, and it is what
lets the
arithmetic live in one place.
Depends on #221449; the first commit is from that PR.
Tested on gfx90a: `llvm/test/Transforms/{OpenMP,Attributor}` 260 passed,
1
unsupported. No kernel in the AOMP smoke and smoke-fort suites changes
execution
mode.

[CIR] Remove the NYI test case for a pointer-element vector (#223019)
#222736 removed CIR_AnyPtrType from VectorElementType, so `!cir.vector<2

x86_64-aggregate-nyi.cir parsing at all, so the whole test fails rather
than just that case.
The case only pinned that the x86_64 bridge refuses the shape. No C or
C++ source produces it, since clang rejects a pointer element with
"invalid vector element type", so the verifier is the earlier and better
place for that rejection. The comment in isSupportedType justifying the
bridge-side exclusion is also removed.

The test has lived downstream since the fix that made the function take
its DWARFDie by value instead of by pointer, where the pointee went out
of scope during the walk. Give it a debug map of its own describing
member-hash/2.o rather than extending the shared dummy-debug-map.map,
which describes a different set of objects.

[CIR][NFCI] Refactor uses of 'mlir::Location' vs 'SourceRange' on calls/etc (#222981)
As a prerequisite to an upcoming patch, emitCall needs access to the
Clang source locations, not just the mlir::Location. We're going to need
this in quite a few more places in the future, since there are various
diagnostics that use clang locations in the code generation.
This patch also has to change the RAII source location stuff, which I
switched to SourceRange. This should improve the amount of data we give
for our source information.
I DID have to remove the assertion on it though, because we do have a
few places that intentionally wanted an invalid location if other stuff
wasn't available (see the CUDA use in particular), but otherwise this
should allow us to improve our source location info, AND use it for
diagnostics in the future.

[Clang] Implement -fkeep-inline-functions (#218533)
Implement the -fkeep-inline-functions flag, which forces selected inline
function definitions to be emitted into the object file even if they
have been inlined into all their callers. The function retention
behavior follows GCC's semantics.
The front-end has been modified to:
- emit the selected functions even if they are unused; and
- add the selected functions to llvm.compiler.used/llvm.used to ensure
they are retained.
The functions selected for emission are inline function definitions that
are available in the current translation unit. available_externally
definitions are excluded because their authoritative definitions are
expected to be emitted by another translation unit.
This is also done for C99 inline function external definitions with
external linkage, which would normally be emitted into the object file
anyway, to ensure the functions are retained for LTO purposes.
See the proposed Clang documentation update for details on the function
selection criteria.

[RISCV] Change RISCVABI::computeTargetABI() to return Expected<ABI>
Return Expected<ABI> instead of printing to errs()/reportFatalUsageError
internally, so callers decide whether to fall back to the default ABI
or treat the failure as fatal, and so it's unit-testable. Also fold the
duplicated Hard-float 'f'/'d' ABI checks from RISCVAsmParser.cpp and
RISCVISelLowering.cpp into computeTargetABI(), and add RISCVBaseInfoTest
coverage for the error paths.

[BOLT][AArch64][Android] Only the dumping thread can longjmp (#222719)
`__bolt_instr_recovery_active` is a process global flag and the reader
in `boltHandleFatalAndRecover()` runs on any thread. When a dump is in
flight, another thread that fails `assert()` or exhausts `GlobalAlloc`
in `instrumentIndirectCall()` could see the flag set, longjmp with the
dumping thread's buffer and restore the dump thread's sp/fp/lr. This
is wrong since the thread would then run on the dumping thread's stack
and later release a mutex that it does not own or hold.
`GlobalWriteProfileMutex` already serializes the writers, so one buffer
would be sufficient; only the reader side needs to know who owns the
buffer. Replace the flag with `__bolt_instr_recovery_tid` holding the
owner's thread ID, and longjmp only when it matches `__gettid()`. Other
threads will fall through to just record the failure and return.
Added a `__gettid()` syscall wrapper, for aarch64 only.

Reland "[llvm][AArch64] Ensure stack alignment in non-sibcall tail calls with FPDiff" (#220406)
When a caller has a non-multiple of the minimum stack alignment more
argument stack space than the callee it is tail calling, we need to ensure that
the resulting FPDiff's magnitude has been rounded up to a multiple of the
platform's minimum stack alignment.
In this re-land there is a fixup to 234ce03692ede13ffd2fcb35570d801c1e332814,
which, because of the wrong order, wasn't actually moving NumBytes after
FPDiff had been re-aligned.

[SampleProfile] Ignore unsampled callees in profile anchors (#219335)
Sample profiles can retain zero-count callee entries in both flattened
body call targets and
unflattened callsite samples:
```text
probe 12:
foo: 10
cleanup: 0
```
Counting every entry as a distinct callee converts the uniquely sampled
foo callsite into
UnknownIndirectCallee. It then fails to match the direct IR call to foo,
causing valid
samples to be reported as stale.
Ignore zero-count entries when the same location has a sampled callee.
Preserve the existing
behavior for genuine multi-callee sites and locations where every callee
has zero samples.
```text
foo: 10, cleanup: 0 -> foo
foo: 10, bar: 1 -> UnknownIndirectCallee
foo: 0, cleanup: 0 -> unchanged
```
The change covers both:
- flattened call targets from body samples;
- inline callees from unflattened callsite samples.
## Related fixes
This is downstream profile-matching robustness related to #219079.
Those changes prevent invalid pseudo-probe context earlier in the
pipeline. This change
ensures that any zero-sample entries reaching the profile matcher are
not treated as
evidence of another executed callee.
## Tests
Added regression coverage for zero-sample callees, genuine multiple
sampled callees,
flattened body targets, and unflattened callsite samples.

[flang] Do not hoist fir.field_index out of loops (#222891)
Lowering a consumer of a !fir.field value inspects its defining
operation: for a record whose layout is known at compile time the field
becomes an LLVM GEP struct index, which must be a constant, and
otherwise the `field` attribute is read off the defining op. A field
value therefore may not be a block argument.
LICM broke that. fir.field_index is Pure and takes no operands, so it is
trivially loop-invariant and was hoisted out of the loop. Lowering emits
one inside each arm of a construct -- for example the CASEs of a SELECT
CASE that each pass a different component of the same derived type as an
actual argument -- so hoisting them left those arms as
otherwise-identical blocks differing only in that operand. Block merging
then merged them and threaded the field through a new block argument,
and codegen aborted with "must be a constant".
Leave producers of a !fir.field where they are. The arms then differ by
an operation rather than by an operand, so they are no longer merge
candidates. Consumers are unaffected and still hoist: fir.coordinate_of
uses the attribute form of the field, so it does not depend on the
fir.field_index value.
The check keys on the result type rather than on FieldIndexOp so that
any operation producing a !fir.field is covered, and sits in the
predicate shared by the direct-loop and nested-region hoisting paths.

[orc-rt] Refactor RTTI for cross-library support, add C API (#222946)
Identify types by name rather than by the address of a per-type ID
object, so that a type's identity survives crossing a library boundary:
an object may be constructed by one library and have its type queried by
another, each with its own copy of orc-rt, where per-type addresses
would not agree. Participating classes now declare an RTTIName, which
must be unique across the process.
RTTIRoot records which library produced each value, so same-library
queries still resolve by pointer comparison, and only cross-library ones
fall back to strcmp.
Adds orc-rt-c/support/RTTI.h to expose this to C.
ORC_RT_RTTI_PARTICIPANT and ORC_RT_C_RTTI_IMPL declare and define a
per-type cast entry point, reached via ORC_RT_DYNCAST, alongside
orc_rt_RTTIRoot_getTypeName for logging. This replaces the
orc_rt_Error_TypeId API (orc_rt_Error_getTypeId,
orc_rt_StringError_getTypeId), which exposed ID addresses and so could
not work across libraries. orc_rt_ErrorRef moves from CoreTypes.h to
Error.h.
RTTICrossDylibTest checks identity across a real boundary: its helper
library links its own copy of orc-rt-bedrock, giving it a distinct
library ID.

[flang][OpenACC] Allocate bufferized recipe descriptors in device memory (#223028)
ACCRecipeBufferization places the descriptor of a bufferized recipe
clause next to the variable it holds. When the clause sits inside a
compute construct and the variable is already produced by a data entry
operation, that memory is host memory no data clause maps, so device
code reading the descriptor through it gets a host address.
Place the descriptor in the construct region in that case. The region is
device memory and needs no data clause of its own, and the mapped
variable is a legal live-in since a data entry operation produces it.
The region entry block is used rather than the clause operation so that
a clause on a nested loop does not allocate on every iteration.

[mlir][OpenACC] Restrict implicit data to compute constructs (#222759)
acc.kernel_environment contains host-side preparation around an outlined

all of its live-ins as implicit device mappings can map
compiler-generated host operations and assign them kernels-style copy
semantics.
Limit ACCImplicitData to parallel, kernels, and serial. In particular,
do not process kernel_environment or the lowered compute_region form.

[CodeGen][SafeStack] Successful InlineFunction should force a recalculation of potentially stale DominatorTree (#222820)
In commit 51a25846c198, Safe Stack began preserving the `DominatorTree`
by the end of the pass' run. Updates to the `DominatorTree` were then
made lazily via inclusion of `DomTreeUpdater` and its use with
`SplitBlockAndInsertIfThen`. Preservation was maintained when updated to
the new pass manager in 3bd517205799. However, there was an overlooked
case where the `DominatorTree` would remain stale by the end of the Safe
Stack pass if the actions under `TryInlinePointerAddress` completed
successfully and modified the caller's CFG.
The conditions for a stale `DominatorTree` to exist are roughly:
1. Safe Stack obtains the Unsafe Stack pointer location as a `CallInst`
(i.e. one way is `-safestack-use-pointer-address`)
2. `__safestack_pointer_address` is defined and inlined successfully.
3. The inlining changes the CFG such that a recalculated `DominatorTree`
would differ.
4. `DominatorTree` remains unchanged since it is preserved and currently
not recalculated.
Here's a simple example that demonstrates the issue:
```
@unsafe_stack_pointer_a = thread_local global ptr null
@unsafe_stack_pointer_b = thread_local global ptr null
declare i32 @get_runtime_mode() nounwind willreturn memory(none)
declare void @escape(ptr)
define ptr @__safestack_pointer_address() alwaysinline {
entry:
%first = call i32 @get_runtime_mode()
%use_a = icmp eq i32 %first, 0
br i1 %use_a, label %a, label %b
a:
ret ptr @unsafe_stack_pointer_a
b:
ret ptr @unsafe_stack_pointer_b
}
define i32 @caller() safestack {
entry:
%unsafe = alloca i32, align 4
call void @escape(ptr %unsafe)
%second = call i32 @get_runtime_mode()
ret i32 %second
}
```
```
> opt -mtriple=x86_64-pc-linux-gnu -safestack-use-pointer-address -passes=require<libcall-lowering-info>,function(safe-stack,verify<domtree>) -disable-output example.ll
DominatorTree is different than a freshly computed one!
Current:
=============================--------------------------------
Inorder Dominator Tree: DFSNumbers invalid: 0 slow queries.
[1] %entry {4294967295,4294967295} [0]
Roots: %entry
Freshly computed tree:
=============================--------------------------------
Inorder Dominator Tree: DFSNumbers invalid: 0 slow queries.
[1] %entry {4294967295,4294967295} [0]
[2] %a.i {4294967295,4294967295} [1]
[2] %__safestack_pointer_address.exit {4294967295,4294967295} [1]
[2] %b.i {4294967295,4294967295} [1]
Roots: %entry
```
To avoid a stale `DominatorTree` by the end of the Safe Stack pass, I
propose calling `recalculate` on the `DominatorTree` for the function
which will have the call to `__safestack_pointer_address` inlined
assuming the inlining was successful and `DomTreeUpdater` is non-NULL.

This warning was enabled by default for clang 23 (although reverted in
23.1.1). Given someone might enable it in the future and the cleanup
seemed nice, we should just do it.
This was done primarily by removing static from templates in headers and
then deleting any unused templates in translation units.
Previously attempted to land this in #221480, but accidentally merged
into a user branch rather than main.

[IVDescriptors] Implement MonotonicDescriptor (#214490)
RFC link:
https://discourse.llvm.org/t/rfc-loop-vectorization-of-compress-store-expand-load-patterns/86442
"Monotonic" variable is similar to induction variable, but its value is
updated under some condition, e.g.:
```
int idx = 0;
for(int i = 0; i < n; ++i) {
// some uses of idx
if (cond)
++idx;
}
```
In this example, `i` is induction variable and `idx` is monotonic
variable: it's updated only when cond == true. In LLVM IR, this looks
like:
```
loop_header:
%monotonic_phi = phi [ %start, %preheader ], [ %update, %latch ]
br i1 %do_step, label %step_bb, label %latch
step_bb:
%step = add/gep %monotonic_phi, %step_val
br label %latch
latch:
%update = phi [ %monotonic_phi, %loop_header ], [ %step, %step_bb ]
br label %loop_header
```
This initial patch only matches the case where `%update` directly
selects between the `%monotonic_phi` or the step. We also limit the
descriptor to only matching cases where all users of the
`%monotonic_phi` are loads/stores that can be mapped to expandloads or
compresstores.
This is a continuation Sergey Kachkov's patch (#140720).

[AArch64] Form CCMP for CBB and CBH (#221113)
AArch64ConditionalCompares forms CMP/CCMP chains to transform patterns
such as
Head Head
/ | CmpBB
/ | / |
| CmpBB => / |
| / | Tail |
| / | | |
Tail | | |
| | | |
... ... ... ...
where Head is terminated by a conditional branch and CmpBB contains
a cmp + conditional branch.
We usually try to split any fused conditional branches to be able to
form CCMP. However, in the case of CBB and CBH, splitting the fused
conditional branch in CmpBB could require the insertion of explicit
zero- or sign-extensions for both operands. In the Head block we can
cheaply fuse at least one of the extensions into cmp.
We therefore convert CBB and CBH unconditionally when we find them in
the Head block. In the CmpBB block, we only do the transformation if
neither operands needs an extension.

[llvm] Avoid PREL32 overflow to .data.rel.ro on AArch64 and re-enable (#222809)
Under the [AArch64 Small Code
Model](https://github.com/ARM-software/abi-aa/blob/main/sysvabi64/sysvabi64.rst#code-models),
the text segment (containing .text and .rodata) is limited to 2GB, but
the combined span of text and data segments can be up to 4GB.
When a relative lookup table is emitted in .rodata but references target
operands that require dynamic relocations (placed in .data.rel.ro in the
data segment), the distance between .rodata and .data.rel.ro can legally
exceed the 2GB range of signed 32-bit R_AARCH64_PREL32 relocations.
In this PR:
1. Ensure that on AArch64, lookup table operands do not need dynamic
relocations. If the lookup table were in `.rodata` (text segment), then
any of the target components would need to be in the data segment, so
the dynamic reloc check would suffice.
2. Re-enable RelLookupTableConverter for AArch64 (while keeping Darwin
disabled as before).
3. Limit the existing `AArch64/no_relative_lookup_table.ll` test to just
darwin aarch64.
4. Move the `X86/relative_lookup_table.ll` into the parent dir since
those checks are (mostly) generic, and allow those same checks to be run
for aarch64. That also includes a minor refactor for not checking the
`unnamed_addr` bit since `unnamed_addr` is
[dropped](https://github.com/llvm/llvm-project/blob/6959b7d081df5fb2349e67e0d8e8e87841fa10d9/llvm/lib/Transforms/Utils/RelLookupTableConverter.cpp#L82)

[OpenMP] [Flang] Add Fortran integer(kind=8) overloads for omp_lib APIs (#221451)
Fortran code that uses integer(8) arguments, including
-fdefault-integer-8, did not match omp_lib interfaces declared with
omp_integer_kind (typically kind 4). Added *_8 specific procedures to
named generic interfaces in omp_lib, exported matching Fortran and C
runtime entry points, and implemented the *_8 functions as thin wrappers
that saturate-convert arguments to 32-bit and call the existing APIs.

[Flang][Driver]Implemented support for option -momit-leaf-frame-pointer/-mno-omit-leaf-frame-pointer in flang (#216700)
Added support for `-momit-leaf-frame-pointer` /
`-mno-omit-leaf-frame-pointer` in the Flang compiler.
- The driver resolves the flags via `getFramePointerKind()` and forwards
`-mframe-pointer=<kind>` to flang -fc1, resulting in the LLVM IR
function attribute "frame-pointer"
- These options, used with `-fno-omit-frame-pointer`, control whether
leaf functions (functions that don't call other functions) retain or
omit the frame pointer.
- `fno-omit-frame-pointer -momit-leaf-frame-pointe`r : Keep the frame
pointer in non-leaf functions, but omit it in leaf functions (produces
"frame-pointer"="non-leaf").
- `fno-omit-frame-pointer -mno-omit-leaf-frame-pointe`r : Keep the frame
pointer in all functions, including leaf functions (produces
"frame-pointer"="all").

IR: Introduce "thread-model" module flag (#222768)
Introduce the replacement for TargetOptions::ThreadModel, but
does not yet wire up the uses. This maintains the current values,
but I question if it makes sense to retain "posix" as the default.
POSIX sounds very target opinionated, but isn't used in a non-binary
way anywhere. Alternatively we could have a simple singlethread binary
flag, or name this something more general.
Follows the precedent of float-abi. It happens the triple default
is just POSIX, but theoretically targets like AVR should be defaulting
to singlethread.

[RISCV] Add PseudoTAILX7, PseudoTAILReg for cf-protection-branch (#220657)
Previously, PseudoTAIL selected between X6 and X7 at encode time by
checking the Zicfilp feature bit via getTailExpandUseRegNo. This is
incorrect for the codegen path because -fcf-protection=branch can emit
lpad without requiring Zicfilp to be enabled.
Add PseudoTAILX7 for codegen: when cf-protection-branch is active,
ISelLowering and the machine outliner now emit PseudoTAILX7 which
always expands using X7. The existing PseudoTAIL behavior is unchanged
— it still selects X6 or X7 based on Zicfilp at encode time, as
documented in the assembler manual.
Also add PseudoTAILReg ("tail address, register") assembly form that
lets users explicitly specify the scratch register for AUIPC+JALR
expansion, per the proposed syntax in
https://github.com/riscv-non-isa/riscv-asm-manual/pull/227.

[orc-rt] Reduce SimpleRemoteCA to transport-independent utils (#223141)
Reduce SimpleRemoteCA to the transport-independent parts: opcodes, setup
and hang-up payload encoding, message validation and dispatch, and the
table of calls awaiting a result. Subclasses are now responsible for the
connection state and synchronization, since they'll usually want to
implement these things for their transports anyway (or the transport
will already manage connection-state/synchronization).
takePendingCall becomes pure virtual, since subclasses must synchronize
access to the pending-call table.
The header moves from orc-rt-internal/ to orc-rt/: with the transport a
subclass concern, there's no reason to preclude library clients from
writing one.

[clang][ARM] Use sponentry for setjmp on Windows ARM32 (#222366)
On Windows, _setjmp and _setjmpex take a second argument, the frame,
which the CRT stores in the jmp_buf and which longjmp later hands to
RtlUnwindEx as the frame to unwind. On aarch64, this is the stack pointer
on entry to the function, while x86_64 takes the function frame address.
ARM expects the same as aarch64 here, the stack pointer on entry.

[KnownFPClass] Restrict KnownFPClass::bitcast/toKnownBits deductions to verified FP semantics (#221133)
`KnownFPClass::bitcast` and `KnownFPClass::toKnownBits` previously made
deductions for floating-point semantics whose bit representations had
not been verified.
I have made it so `KnownFPClass::bitcast` and
`KnownFPClass::toKnownBits` return `fcAllFlags`/unknown for any
`APFloat` semantics we have not verified. Currently, this prevents
potentially invalid deductions for `PPCDoubleDouble` (mostly in regards
to the signbit and endianess). It also allows these functions to be
"safely" used with the 4/6/8 bit floating point types since we
conservatively return unknown.
Currently the list of supported/verified semantics for both `bitcast`
and `toKnownBits` are:
```
IEEEhalf
BFloat
IEEEsingle
IEEEdouble
IEEEquad
x87DoubleExtended
```

check that explicit constructor calls work at compile time.
However, the test case left var.a uninitialized and the copy constructor
reads an unitialized value. MSVC diagnoses this, but clang currently
fails to do so.
Change the test case to remove the unrelated problem of an uninitialized
read.

[CMake] Disable linker version scripts for Emscripten (#221647)
Emscripten reports itself as a Unix-like CMake platform, causing LLVM to
set `LLVM_HAVE_LINK_VERSION_SCRIPT` and pass GNU/ELF `--version-script`
options when linking shared libraries.
Emscripten uses `wasm-ld`, which does not support GNU version scripts
and currently reports:
```
em++: warning: ignoring unsupported linker flag: `--version-script`
```
Treat Emscripten like the other platforms without version-script
support. This prevents LLVM and Clang shared-library targets from
passing an unsupported linker option.
This was encountered while building LLVM 23.1.0 for both wasm32 and
wasm64 with Emscripten 6.x in emscripten-forge.

[lldb] Bound Mach-O symtab allocation to the file size (#222955)
Opening a Mach-O file whose LC_SYMTAB claims far more symbols than the
file could possibly hold makes lldb ask for hundreds of gigabytes. A
128-byte file with LC_SYMTAB.nsyms = 0x80000000 (the new unit test's
input, built with yaml2obj) reproduces it through `lldb-target-fuzzer`,
the harness that found this bug:
```
==45515== ERROR: libFuzzer: out-of-memory (malloc(171798691840))
#8 std::__1::__split_buffer<lldb_private::Symbol,...>::__split_buffer(...)
#9 std::__1::vector<lldb_private::Symbol,...>::resize(unsigned long)
#10 lldb_private::Symtab::Resize(unsigned long)
#11 ObjectFileMachO::ParseSymtab(lldb_private::Symtab&)
```
`ParseSymtab()` sizes the destination `Symtab`'s `vector<Symbol>`
directly
from `nsyms` and `nindirectsyms`, two counts read from the file's
`LC_SYMTAB` and `LC_DYSYMTAB` commands. `nlist_data`, the view already
built earlier in the function from the bytes the file actually has at
`symoff`, is far smaller than what those counts claim; the guard gating
this code only checks that it is non-empty, not how many nlist records
it can back.
Bound both counts by what `nlist_data` and `indirect_symbol_index_data`
(already clipped to the available bytes) can hold, instead of trusting
the file's counts outright.
Add a unit test whose LC_SYMTAB claims about two billion symbols in a
128-byte file; completing quickly instead of reserving that much space
is the regression check.

[DAGCombiner] Only fold shift+mask compare to rotate if the shift amount divides the bit width (#220743)
DAGCombiner::visitSETCC can turn `(X << S) == (X & -(1 << S))` (or the
srl variant) into `rotl(X, S) == X`, and the other way around, when the
target prefers one form over the other. The two forms are only equivalent when
S divides the bit width. The check used `isPowerOf2(S)`, which is the same
thing for i8/i16/i32/i64 but not for odd widths like i3, where S = 2 is a
power of two that does not divide 3. On x86, which prefers the rotate,
the reporter's i3 function returned the wrong value for two of its eight
inputs.
This changes the `MayTransformRotate` flag passed to
`preferedOpcodeForCmpEqPiecesOfOperand` to check `NumBits % S == 0`
(with S != 0) and fixes the two comments that described the old rule. For legal
scalar types nothing changes. On illegal non power of two widths this
also lets a non power of two amount that divides the width use the rotate
(like i6 with S = 3); that is correct for the same reason and legalizes
through the usual rotate promotion, same as i6 with S = 2 did before. The x86
hook already honors the flag in both directions, so the fix lives in the
target independent code.
Tests: the i3 shl and lshr cases from the issue (must stay shift+mask), an
i6 / S = 3 case (3 divides 6, so the rotate is still allowed), and the
reporter's function.
Fixes #220542

[NFC][ModuleUtils] Move externalize() from module splitting utilities (#221181)
`SplitModule.cpp` and `AMDGPUSplitModule.cpp` each carry an identical
static `externalize()` helper that promotes local-linkage globals to
external + hidden visibility and assigns a stable name to unnamed
entities, so they are named consistently across module partitions.
This patch removes the duplication by moving the helper into
`ModuleUtils` as `llvm::externalize`, and updates both users to call the
shared implementation. No functional changes are intended.
This also prepares for upcoming module splitting utilities to reuse a
single, canonical implementation.
Development of this patch was assisted by AI and reviewed by me.

[KnownFPClass] Unify and refine interested classes for `KnownFPClass::log` (#219751)
Previously, `ValueTracking` and `GISelValueTracking` only called
`KnownFPClass::log` when the requested classes included NaN or infinity.
As a result, narrowly interested queries could miss unconditional
deductions, for example, `log(x)` is never subnormal or negative zero
(With the exception of `PPCDoubleDouble`
https://github.com/llvm/llvm-project/issues/217658).
This change makes the interested-class handling consistent between
`ValueTracking` and `GISelValueTracking`. The source is queried only
when its classes are needed, but `KnownFPClass::log` is always called so
its unconditional deductions are preserved.
Future work:
- Fixing `KnownFPClass::log` for `PPCDoubleDouble`.

[MIRParser] Reject a one-element fixed-length vector type (#213290)
MIParser accepts `<1 x sN>` and then asserts while building the LLT, so
llc aborts during parsing instead of reporting a parse error:
```
Assertion `!EC.isScalar() && "invalid number of vector elements"' failed.
```
LLT has no one-element fixed-length vector. `getLLTForType`,
`getLLTForMVT` and
`LLT::changeElementCount` all map a one-element `ElementCount` to the
element
type through `LLT::scalarOrVector`, nothing calls `LLT::fixed_vector(1,
...)`,
and no in-tree .mir test uses the syntax. `verifyVectorElementCount`
already rejects 0 and anything above 2^16, so 1 was the remaining hole; it now
gets the same diagnostic instead of aborting the parser.
Scalable vectors are unaffected: `<vscale x 1 x sN>` is a valid type and
stays legal through the `HasVScale` check.

[Mips] Handle division by zero trap on MIPS1 (#201133)
LLVM currently emits the `teq` instruction for every arch version, but
`teq` is unsupported on MIPS1.
This special cases MIPS1 so that `bne(z)` and `break` are emitted
instead.
Compared to https://github.com/llvm/llvm-project/pull/81311, this should
also handle liveness as far as I can tell.
I didn't want to add another bool to the argument list so I combined
`IsMicroMips` and what was supposed to be `IsMips1` into an enum, which
feels much nicer in this case.
Besides that and the main change, I also changed the `hasSideEffects`
bit for `PseudoSDIV` and `PseudoUDIV`,
which allows the delay slot to be usefully filled - well, at least with
`-O1`+. This seems to be in line with what GCC does:
https://godbolt.org/z/zqcG5ha35
Tested using clang directly and through Zig's LLVM backend.

[mlir][vector] Don't fold in_bounds for negative constant indices (#219681)
`isInBounds` checked only that the transfer *ends* inside the source:
return cstOp.value() + vectorSize <= sourceSize;
The `in_bounds` attribute promises more than that. Its definition in
VectorOps.td says accesses "(including the starting point)" may run
out-of-bounds when it is "false", so setting it to "true" is a claim
about the start of the transfer as well as its end.
With a negative constant index the two disagree. For
vector.transfer_read %m[-1] : memref<8xf32>, vector<4xf32>
`-1 + 4 <= 8` holds, so the fold set `in_bounds = [true]`, even though
element -1 is read from outside `%m`.
The same expression also overflows for a large enough index: at `index =
2^63 - 1` the addition wraps and the fold again reports `in_bounds =
[true]`. Computing the bound as `sourceSize - vectorSize` instead avoids
the addition entirely; both operands are static, non-negative dimension
sizes, so the subtraction cannot overflow.
This is a spec-conformance fix, not a live miscompile report. A negative
index into a memref is already undefined behaviour, and the masked
lowering would not have caught it either: the guard
`generateInBoundsCheck` emits in VectorToSCF is `memrefDim > index +
iv`, an upper-bound check only.
Adds three regression tests, each of which fails without the change.

[ValueTracking] Propagate non-negativity through fptosi (#217868)
Fixes #217442
`fptosi` is poison when the rounded value does not fit in the result
type, so `computeKnownBits` can assume the conversion rounds towards
zero without wrapping. Negative subnormals and negative zero always
round to 0, so only sources known to never be a negative normal or
negative infinity (i.e. values <= -1.0) can produce a negative result.
This lets InstCombine fold `(int)fabs(x) < 0` to `false`, matching GCC,
and also benefits other magnitude-clamping intrinsics such as sqrt.

[MachineScheduler] Order fixed-FI memory operations by object offset (#219669)
## Summary
- sort fixed frame-index memory operands by their explicit stack offsets
- preserve the existing frame-index ordering for ordinary stack objects
and as a tie-breaker
- add an AArch64 MIR regression with fixed objects created out of offset
order
## Background
`BaseMemOpClusterMutation` currently orders frame-index bases by
frame-index number, adjusted for the stack growth direction. Fixed frame
objects are different from ordinary stack objects: they carry explicit
offsets, and their creation order is not required to match address
order.
As a result, a target clustering hook can receive two fixed objects in
reverse address order. AArch64's `shouldClusterFI` expects the incoming
fixed-object offsets to be ordered and aborts with `Object offsets are
not ordered` in an assertions-enabled build.
When both operands refer to fixed frame objects, compare their
`MachineFrameInfo` object offsets first. The existing frame-index
comparison remains the fallback, so the ordering of ordinary stack
objects is unchanged.
Make the ordering between fixed and non-fixed frame-index bases
explicit: non-fixed bases precede fixed bases for downward-growing
stacks, while fixed bases precede non-fixed bases for upward-growing
stacks. This preserves the existing cross-category ordering without
relying on non-fixed object offsets before frame layout.
The regression deliberately creates two fixed objects in an order that
disagrees with their explicit offsets. It covers both the legacy and new
machine-scheduler pass forms.

[TableGen] Use BitVector for RegisterSet in AsmMatcherEmitter (NFC) (#222525)
This patch replaces std::set with BitVector for RegisterSet in
AsmMatcherEmitter.
Without this patch, RegisterSet is represented as
std::set<const Record *, LessRecordByID>. On targets with large
register files like AMDGPU (~3,000 registers), repeatedly computing set
intersections and subset checks using std::set nodes incurs
significant overhead.
This patch assigns each register record a dense bit index ordered by
LessRecordByID. This allows us to represent RegisterSet as a
BitVector, enabling fast bitwise operations for set intersections and
subset checks.
This reduces the wall-clock time of generating AMDGPUGenAsmMatcher.inc
from 39.53s to 31.32s (a 20.8% speedup) across 3 runs while producing
bit-for-bit identical output across all targets.

## Summary
Add KnownBits support for `G_INSERT_SUBVECTOR` in GlobalISel value
tracking.
The implementation splits the demanded elements between the original
vector and inserted subvector, ignores overwritten source elements, and
intersects the KnownBits information from the contributing operands.
Part of #150515.

[orc-rt] Build RTTICrossDylibTestLib with ORC_RT_COMPILE_FLAGS (#223144)
Without ORC_RT_COMPILE_FLAGS, the test library builds with C++ RTTI on
by default. This leads to link errors when the ORC runtime is built with
C++ RTTI turned off.

[orc-rt] Add ORC_RT_BEDROCK_LIBRARY_TYPE (STATIC/SHARED) (#223288)
Add CMake options to build bedrock as either a static or shared library.
Default is static.
This is CMake infrastructure only. Shared library builds aren't actually
useable yet: bedrock doesn't export its C++ API, and its C API is
insufficient to do anything interesting. Tools and test code are updated
to link against the -object libraries directly, since they use the
(unexported) C++ API.

[libc] Implement pthread_attr_[gs]etschedparam (#222991)
This patch implements pthread_attr_setschedparam and

Like the schedpolicy patch, this commit only operates on the
pthread_attr_t object and does not attempt to install scheduling
parameters when creating a new thread.
I also don't attempt to validate the priority value here. The valid
priority range depends on the scheduling policy (which may not even be
set yet or could change later), and we can let the kernel validate the
parameters when creating the thread or setting scheduler settings.
While in there:
- update the file headers to the modern llvm format
- use proxy headers instead of direct pthread.h inclusion

[IR] Simplify ValueAsMetadata::handleRAUW. NFC (#223301)
Metadata refers to a Value through its unique ValueAsMetadata wrapper.
When a Value is RAUW'd, handleRAUW reuses the old value's wrapper for
the new value if the new value has none yet; otherwise it moves the uses
to the new value's wrapper, with special cases for a local becoming a
constant, a constant becoming a local, and a value moving to another
function.
Always move the uses (or drop them in the last two cases) and delete the
old wrapper, so that a ValueAsMetadata wraps the same value for its
whole life.
Instruction counts for SLPVectorizer.cpp and X86ISelLowering.cpp at -O2
-g are unchanged (-0.04%, -0.01%).

Add Clang header intrinsics for the RISC-V P-extension packed widening

- __riscv_pwadda_i32x2
- __riscv_pwaddau_u16x4
- __riscv_pwaddau_u32x2
The header wrappers use generic LLVM IR. RV32 selects the direct
`pwadda.*` / `pwaddau.*` instructions. RV64 lowers the generic IR to the
decomposition specified by the P-extension intrinsic spec, including
`zip16p + pli.h + pm2adda.h/pm2addau.h` for the halfword forms.

[TargetInstrInfo] Enable instruction size verification by default (#221687)
Enable verification for instruction sizes by default. When emitting
machine code, this checks that the reported instruction size is not
smaller than the actual instruction size. Not under-reporting
instruction sizes is critical for any target that does branch relaxation
(or similar) on MIR.
The default allows over-estimating the size. Targets can opt-in to
precise instruction sizes if they want.
Exclude two instructions on ARM, which report incorrect sizes, but
fixing those sizes breaks the constant islands pass for some reason.

[Allocator] Don't overestimate alignment for operator new (#223300)
On many platforms with alignof(max_align_t)=16, when sizeof(T) == 24,
The placement new overestimates the alignment to 16:
`std::min(llvm::bit_ceil(Size), alignof(std::max_align_t)) = min(32, 16) = 16`.
We can use a better estimate: `min(countr_zero(Size),
alignof(max_align_t))`, which is hand-optimized to the form in the code.

[RISCV] Lower f16 to i64 fp_to_[su]int via i32 on RV32 (#222829)
i64 is not a legal type on RV32, so f16 to i64 conversions used to be expanded to a __fixhfdi/__fixunshfdi libcall, which compiler-rt does not provide. f16 is the only FP type whose finite values always fit in an i32 after truncation towards zero, so custom expand them to an i32 conversion plus an extension instead; out of range values and NaN are poison, so the fcvt clamping is acceptable. With only Zfhmin/Zhinxmin the i32 conversion promotes f16 to f32, and both imply F/Zfinx so f32 is always legal. Other FP source types keep using the libcall.

[RISCV] Rewrite ADD to SUB to reuse a materialized negated constant (#221027)
When an ADD needs a large constant whose negation is already
present in the DAG, rewrite (add X, C) into (sub X, -C) so both
share one materialization of -C instead of building it twice.
selectNegImm already does a related rewrite, but only when -C is
strictly cheaper than C and during instruction selection, where the
sibling constant may already have been selected into instructions.
Do it in PreprocessISelDAG instead, before selection, while both are
still ConstantSDNodes that getConstant can unique together. The
rewrite only fires when -C is no more expensive than C and a node
holding -C already exists, so it never adds a materialization.

[libc++] Provide aligned allocation function iff the compiler claims support (#219199)
There isn't much of a point to providing declarations for aligned
allocation functions but not allowing the compiler to use them. So
either aligned allocations should be allowed to be used via
`-faligned-allocation` or not provided at all.

[MLIR][OpenMP] DeclareTargetInterface and DeclareTargetAttr cleanup (#217295)
The changes introduced by this patch are intended to avoid triggering
multiple by name lookups to the "omp.declare_target" attribute every
time any data from the `DeclareTargetInterface` is queried, remove the
need for keeping multiple default values for the same data, clean up the
assembly format and generally improve the usage of the interface.
List of changes:
- `DeclareTargetInterface` only provides `setDeclareTarget` and
`getDeclareTarget` methods to handle the "omp.declare_target" attribute,
maintaining a single canonical way of accessing it.
- `DeclareTargetAttr` provides direct access to the capture clause and
device type enums, rather than wrapping them into an `Attribute`. These
are now mandatory as well. Both changes together make accessing them
more straightforward and simplify the attribute representation.

[X86] Fix `"Cannot select"` for `bf16` vector selects on a scalar condition under `AVX10.2` (#222854)
Fixes #222673
A `select i1 %c, <8 x bfloat> %a, <8 x bfloat> %b` failed instruction
selection with `+avx10.2-512` on a `v8bf16 X86ISD::CMOV`. Selects on a
scalar condition are lowered to the `CMOV_VR*` pseudos and expanded to a
branch, but those pseudos only have patterns for integer and f16
vectors. Before #101603 bf16 vectors were treated as "soft" everywhere,
so `LowerSELECT` bitcast them to `v8i16` first and never produced a bf16
CMOV. That PR made bf16 non-soft under AVX10.2 to enable native
arithmetic, which silently removed the only bf16-aware path in
`LowerSELECT` without adding a replacement. `v16bf16` and `v32bf16` hit
the same thing.
`LowerSELECT` now takes the integer-bitcast path for every bf16 vector,
using the existing `isBF16orSoftF16` helper, so the select is lowered
exactly as it is on every other bf16 target and as `v8f16` is on FP16
targets. Scalar `bf16` is soft-promoted to `f32` before lowering, so it
is unaffected. Added `pseudo_cmov_lower-bf16.ll` alongside the f16
sibling, covering the reproducer plus `v8/v16/v32bf16` on both
`+avx512bf16,+avx512vl` and `+avx10.2-512`.

[lldb] Memory cache: no overlap and read across cache entries (#222688)
The memory cache keeps two collections of cached bytes, L1 and L2, which
are named confusingly. L2 holds cache lines at aligned addresses, but
each line size is less than or equal to the fixed line size. L1 holds
pieces from arbitrary addresses with arbitrary lengths. This caused two
problems:
1. A lookup had to find every byte it wanted inside a *single*
entry. A range that spanned two adjacent entries missed even when the
two collections together already held every byte of it. The lookup
rejected such a read rather than take part of it from each entry.
2. The pieces could also overlap each other, which made the lookup
incomplete as well as ambiguous. It examined only the piece starting at
or below the address, so a short piece hid a longer one that covered the
whole read. The read missed with the bytes resident.
This change fixes these problems by introducing these properties to the
cache:
- At most one collection holds any given address.
- The line collection holds only whole, aligned lines (`LineCache`).
- The piece collection holds only fragments smaller than a line, and
they never overlap each other (`ChunkCache`).
- A read takes what it needs from consecutive entries in turn until a
miss (`ReadFromCaches`).
- `AddCacheData` (renamed from `AddL1CacheData`) splits incoming bytes
at line boundaries and drops bytes already held, so callers no longer
pick the cache tier.
Disjoint entries make the cache simple to reason about:
- A read no longer depends on which copy of an address is found first,
because there is only one.
- Probing one candidate is now complete. Since entries cannot
overlap, the entry starting at or below an address is the only one
that can hold it. No byte is stored twice.
- Invalidating an address touches one entry, with no second copy
elsewhere to find and drop.
- Callers of the cache need no knowledge of cache internals.
`ReadRanges` also uses `ReadFromCaches`. Previously, each requested
range had to fit entirely within a single cache entry. Ranges can now
be served across multiple entries and line boundaries. For example,
`Process::ReadCStringsFromMemory` reads strings in 256-byte windows.
Because strings start at arbitrary offsets, these windows frequently
span
two adjacent cache lines. Under the old lookup, such a window missed in
`ReadRanges` even when both lines were resident. It now hits from cache
across the line boundary.
`Flush` now drops all cached entries that intersect the range instead of
erasing only the entry matching the start address. It uses saturating
addition to prevent address wraparound. Its runtime is bounded by the
number of cached entries rather than the range size.
`GrowReadRange` isolates the read-ahead policy from `Read`. It aligns
the read address down to the line base so fetches land in `LineCache` as
whole lines. It caps read-ahead to two lines, skips the last line if
already resident, and clips the read at invalid ranges.

[AMDGPU] Mark `SI_WATERFALL_LOOP` as divergent in `hasDivergentBranch` (#218969)
When a vector instruction takes an SGPR source operand, sinking it out
of a loop with divergent exit would cause the vector instruction to only
get the value from the last iteration in the SGPR. However, in a
divergent loop the value of the SGPR operand may vary across iterations,
so the instruction cannot be sink out of the loop as only using the last
value is incorrect. Before this change `SI_LOOP` was marked as divergent
but `SI_WATERFALL_LOOP` was not, allowing such incorrect sinking for
waterfall loops.

[dfsan] Fix big-endian origin mask (#223247)
Fix the mask used when loading wide shadows on big-endian targets.
The previous expression used a 32-bit integer for the shift, producing
an incorrect zero mask for 64-bit wide shadows. Changed the expression
to use 1ULL so that a 64-bit mask is constructed correctly. The
resulting mask keeps the upper 32 bits and clears the lower 32 bits.
Previously, the big-endian path generated:
```ll
%10 = load i64, ptr %6, align 1
%11 = and i64 %10, 0
```
With this change, it generates:
```ll
%10 = load i64, ptr %6, align 1
%11 = and i64 %10, -4294967296
```
Added a SystemZ big-endian regression test.

[analyzer] Resolve lambda captures for explicit object parameters (#219726)
Currently explicit object parameters are not modeled in the
`VisitCommonDeclRefExpr` function in `ExprEngine`. Because of this when
a lambda has an explicit object parameter and a possible division by
zero the `core.DivideZero` checker does not emit warning. This PR solves
that issue by deciding if the lambda has an explicit object parameter
and then records the binding (if the parameter has the reference type)
between the parameter and the argument's expression otherwise it returns
the captured field's lvalue.
This PR fixes #218708

[SROA] Use SparseBitVector for splittable offsets (#222306)
Doing this means we consume memory proportional to the number of
offsets, not the size of the alloca as before. Inverting the logic so
that rather than initially marking all offsets as splittable then
removing those that aren't, we instead initially have all offsets
unsplittable and only add those that are splittable, means we should
take time proportional to the number of slices, not to the combined size
of slices.
This means we can remove the limit on alloca size, and this approach
should also be faster.

[mlir][memref] Keep memref.load attributes when eliding reinterpret_cast (#221314)
`RewriteLoadFromReinterpretCast` rebuilds the load on the source of the
`memref.reinterpret_cast` with the indices remapped to the non-unit
dimensions, but the rebuilt load carries none of `nontemporal`,
`alignment` or `invariant`:
```mlir
%rc = memref.reinterpret_cast %src to offset: [0], sizes: [1, 1, 8], strides: [8, 8, 1] : memref<1x8xf32> to memref<1x1x8xf32>
%0 = memref.load %rc[%c0, %c0, %i] alignment(16) nontemporal(true) invariant(true) : memref<1x1x8xf32>
// -memref-elide-reinterpret-cast today
%0 = memref.load %src[%c0, %i] : memref<1x8xf32>
```
The rewrite only changes how the same element is addressed, so the three
attributes describe the same access. This forwards them. Same shape of
fix as #221312 for `gpu-decompose-memrefs`.

pseudoToMCOpcode() used the D16Buf TSFlag to switch individual instructions to
the GFX80 encoding family on subtargets with UnpackedD16VMem. Select GFX80 for
the whole subtarget instead, and fall back on VI when a pseudo has no GFX80
real. That is what the flag was encoding anyway: only buffer instructions with
unpacked D16 data have a GFX80 encoding.
D16Buf is now unused, so remove it and free up TSFlags bit 50.

[mlir][dataflow] Deduplicate data-flow solver worklist items (#221983)
The solver enqueues a work item every time a state it depends on
changes, so the same item can appear in the worklist many times.
A duplicate work item is re-processed even though its inputs have not
changed since the previous processing. For example, a dense analysis can
visit a join point with N predecessors up to N times in a row.
To deduplicate the worklist, pending items are tracked using a
`DenseSet`, and an item that is already pending is not pushed again.
Items are removed from the set when dequeued, before being visited, so
an analysis can still re-enqueue the point it is currently visiting.
Since analyses already have to be monotone to reach a fixed point, this
change does not affect analysis results, only the number of visits until
convergence. The test `FooState` used XOR for the join operation, which
is not monotone; the join operation was switched to OR and dependent
tests were updated.
A test that counts how many times a join block with several predecessors
is visited was added to check the deduplication.

i8 x i8 -> i32: vpdpbusd (AVX512-VNNI, AVX-VNNI)
vpdpbssd / vpdpbuud (AVX-VNNI-INT8, AVX10.2)
i16 x i16 -> i32: vpdpwssd (AVX512-VNNI, AVX-VNNI)
vpdpwsud / vpdpwuud (AVX-VNNI-INT16, AVX10.2)
bf16 x bf16 -> f32: vdpbf16ps (AVX512-BF16)
f16 x f16 -> f32: vdpphps (AVX10.2)
The 128/256-bit shapes, and the 512-bit shapes on targets using 512-bit
registers, are registered as Custom. 512-bit shapes for which only the
VEX
encoding exists are split into two 256-bit dot products, and the
128/256-bit
shapes are widened to 512 bits on targets without VLX.
Teach X86TTIImpl::getPartialReductionCost about these shapes, costing
one
dot product per legal accumulator vector and otherwise falling back to
the
generic expansion cost, so that LoopVectorize can form partial
reductions
for them.
The DAG combiner forms partial reductions with narrower-than-legal types
when the widened shape is supported, so also widen the integer
PARTIAL_REDUCE_*MLA results the same way as PARTIAL_REDUCE_FMLA (expand,
then widen).

[ORC] Carry out-of-band errors in SimpleRemoteEPC results (#223378)
ORC Wrapper functions may produce out-of-band error results (e.g. due to
serialization errors), but SimpleRemoteEPC / SimpleRemoteEPCServer never
handled these cases (they incorrectly asserted that they never
appeared).
Update the SimpleRemote protocol to use the TagAddr field (previously
unused for result messages) to encode Result message kinds: either a
Value, or an OutOfBandError. This allows out-of-band errors to flow
across the wire and be passed as results to their callers.
encodeResultMessage and decodeResultMessage implement the format /
handling: out-of-band errors (or failures to deserialize out-of-band
errors) are now passed to handlers as out-of-band error results. An
invalid Result message kind in the TagAddr field results in an
llvm::Error, ending the session.
SimpleRemoteEPCUtilsTest covers both kinds' round-trips, an unrecognized
kind, and a malformed out-of-band payload.

[analyzer] Chain checkers in runCheckersForEndFunction (#220970)
The function `runCheckersForEndFunction` had an unusual behavior that it
invoked the callbacks in parallel (introducing a new execution path for
each checker callback that produced a transition), unlike all other
analogous functions, which "chained" the checkers, executing them after
each other.
This behavior was introduced before 2011, when this callback was called
`check::EndPath`, to ensure that the `EndPath` callbacks are _final_ and
nodes created by them end up at the end of the execution path. When
interprocedural analysis (inlining functions) was introduced in 2013,
the callback was renamed to `EndFunction` (to reflect that it also
activates at the end of inlined functions), but the unusual behavior was
preserved.
There were 8 "real" checkers with `check::EndFunction` callbacks, but
most of them only created error nodes or did "nice to have" cleanup, so
the irregular behavior of this callback did not cause visible trouble.
However, none of the checkers actually _relies_ on the parallel
execution of the callbacks and the unusual transition pattern seriously
violates the established patterns of the analyzer; so this commit
rewrites `runCheckersForEndFunction` to follow the standard logic.
This may slightly perturb the analysis results (because it changes the
"shape" of the exploded graph), but -- based on my review of the
upstream EndFunction checkers -- should not cause any directed
functional changes.

[lldb] Fix 32-bit narrowing conversions in the memory cache (#223402)
#222688 broke the 32-bit Arm bots. `lldb-arm-ubuntu` fails to
build `Memory.cpp`:
```
lldb/source/Target/Memory.cpp:187:49: error: non-constant-expression cannot be narrowed from type 'lldb::offset_t' (aka 'unsigned long long') to 'size_t' (aka 'unsigned int') in initializer list [-Wc++11-narrowing]
187 | InsertData(addr, {data_buffer_sp->GetBytes(), data_buffer_sp->GetByteSize()});
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
```
`DataBuffer::GetByteSize` returns `lldb::offset_t`, which is always 64
bits wide, while the `llvm::ArrayRef` constructor takes a `size_t`.
Where
`size_t` is 32 bits the conversion narrows, and a braced initializer
list
rejects a narrowing conversion that is not a constant expression. The
same code compiles on a 64-bit host because there `size_t` is just as
wide
as `offset_t` and nothing narrows.
`DataBuffer::GetData` already returns the whole buffer as an
`llvm::ArrayRef<uint8_t>`, so use it rather than build the same
`ArrayRef`
from a pointer and a length.
`MemoryTest.cpp` has eight more of the same error, which the bot never
reported because the build stopped at the first one. They share a single
cause: `line` holds the cache line size, but it was declared `addr_t`
and
the `Chunk` field it initializes is a `size_t`. Give it the type
`MemoryCache::GetMemoryCacheLineSize` returns, `uint32_t`, which is also
the right domain for a size rather than an address.

[CodeGen] Optimize ctpop expansion using computeKnownBits (#221671)
The current SWAR popcount implementation always uses the full register
width for the final accumulation step. Even when the input type is much
smaller, such as when counting the bits of an `i8` value, we still use
32-bit operations to extract the result. This patch uses
`computeKnownBits` to determine the minimum number of bits actually
needed to represent the popcount result, and uses this information to
optimize the SWAR popcount expansion.

[mlir][vector-to-gpu] Lower transposed transfer_write to a transposed MMA store (#221248)
`convert-vector-to-gpu` lowers a `vector.transfer_read` whose
permutation
map puts the most minor dimension first to a `transpose` MMA load since
18ecdbfe6c74, but still rejects the same shape of
`vector.transfer_write`:
```mlir
// Lowered to gpu.subgroup_mma_load_matrix ... leadDimension 3 transpose
%0 = vector.transfer_read %a[%c0, %c0], %f {in_bounds = [true, true], permutation_map = affine_map<(d0, d1) -> (d1, d0)>} : memref<5x3xf16>, vector<3x5xf16>
// Left alone
vector.transfer_write %1, %b[%c0, %c0] {in_bounds = [true, true], permutation_map = affine_map<(d0, d1) -> (d1, d0)>} : vector<3x5xf16>, memref<5x3xf16>
```
The TODO in `transferWriteSupportsMMAMatrixType` waits for a transpose
attribute on the GPU dialect op. `gpu.subgroup_mma_store_matrix` has had
one since 3d35546cd168, and both the NVVM and the SPIR-V lowerings
honour
it, so this classifies the write the same way as the read and sets the
attribute. `leadDimension` already comes from the position of the map
dimensions, so the stride helper is unchanged.
Tests: the existing `no_convert_write_transpose` becomes a positive
test,
plus the 3-D and 4-D strided cases and a not-last-dim negative case,
mirroring the read side. A tensor core integration test runs a
transposed
`transfer_write` through `convert-vector-to-gpu` and the NVVM pipeline
and
checks the stored matrix; it passes on an RTX 3070 (sm_86).

[AMDGPU][GISel] Do not scalarize uniform v2f16/v2bf16 operations (#222359)
Previously, register bank legalization would scalarize uniform v2f16 and
v2bf16
floating-point operations on targets with hasSALUFloat (GFX12+) using
the ScalarizeToS16 action. This approach had two problems:
1. It fails for v2bf16 types because there are no scalar bf16
instructions - the scalarization produces illegal bf16 operations
that cannot be selected.
2. Scalar f16 instructions exist, but scalarization is suboptimal.
Packed instructions
like v_pk_add_f16, v_pk_mul_f16, etc. are more efficient than
unpacking to two separate s16 operations.
This patch removes the ScalarizeToS16 rules and instead adds
unconditional .Uni(V2S16) rules that always use
packed VGPR operations for uniform cases.
Operations modified:
- G_FADD, G_FMUL, G_STRICT_FADD, G_STRICT_FMUL
- G_FSUB, G_STRICT_FSUB
- G_FMA, G_STRICT_FMA
- G_FNEG, G_FABS

has no result for the per-result `res_attrs` array to describe. The
function rewrite and both call rewrites now remove it.

[lld-macho] Parallelize ObjFile::sourceFile() during STABS emission. (#222087)
This is part of the ld64.lld performance improvements tracked by #222068
Currently, SymtabSection::emitStabs() calls emitBeginSourceStab() it
passes in file->sourceFile(), which will call
ObjFile::sourceFile(). This method reads the component's root DIE, which
is a bottleneck when done serially as at this stage the DWARF sections
have not been parsed yet.
This commit parallelizes the calls to ObjFile::sourceFile(), as we
already have the file ids stable sorted.

[mlir][gpu] Keep memref.load/store attributes in decompose-memrefs (#221312)
`gpu-decompose-memrefs` rewrites a `memref.load`/`memref.store` inside a
`gpu.launch` into a `reinterpret_cast` to the linearised offset plus a
0-d access, but rebuilds the op from the new memref only. `nontemporal`,
`alignment` and `invariant` are dropped from the load, `nontemporal` and
`alignment` from the store:
```mlir
%res = memref.load %arg0[%tx, %ty, %tz] alignment(16) nontemporal(true) invariant(true) : memref<?x?x?xf32>
// becomes
%1 = memref.load %reinterpret_cast[] : memref<f32, strided<[], offset: ?>>
```
The rewrite accesses the same element with the same type, so all of
them still hold on the new op. Pass them to the builder; the attribute
form is the one that also carries `invariant`.
Tests: a load and a store case next to the existing `@decompose_load`
and `@decompose_store`.
AI tool use: I worked on this patch together with an AI assistant
(Claude Code).
Every line of the change and the tests was reviewed and verified by me,

[mlir][linalg] Hoist transfer pairs through disjoint subview slices (#220244)
`hoistRedundantVectorTransfers` previously bailed whenever a transfer
pair was based on a view like `memref.subview`, since another view of
the same buffer could alias it. This patch replaces that blanket bail
with an actual aliasing check: the pair is hoisted when no other access
to the base's underlying buffer in the loop conflicts with it, i.e.
every other access is either the matching read/write or a slice provably
disjoint from the base's static per-dimension footprint. When the base
has no static footprint (e.g. a dynamic subview offset or a
collapse_shape root), the pair still hoists as long as nothing else in
the loop touches the buffer; otherwise it conservatively bails.
The check is implemented as a reusable utility
`memref::hasNoAliasingAccessInScope` in MemRefUtils, and the existing
lone-read path (noAliasingUseInLoop) is unified onto it.
Adds lit tests: positive cases for disjoint static subviews, a dynamic
(loop-invariant) offset, and a collapse_shape root; negative cases for
overlapping subviews and an aliasing non-transfer memory effect.

[AArch64] Prohibit vectorizing non-native [de]interleaved pattern for fixed-length SVE (#219244)
This patch prevents LoopVectorize from using non-native interleaved

For wider fixed-length SVE, non-native factors produce awkward wide
shuffles that lower poorly with extra permutes, scalar lane moves, and
sometimes stack traffic. Native interleave factors and NEON-sized fixed
vectors remain allowed.

[DAGCombiner] Require a 0/1 carry-in when rebuilding a borrow chain (#223396)
combineOrOfSetCCToUSUBOCarry (aae871ba1224) rewrites
carry_out = (A <u B) | ((A == B) & carry_in)
to USUBO_CARRY(A, B, carry_in), accepting any value as carry_in.
USUBO_CARRY's third operand is specified as "1 if and only if there is
an incoming carry/borrow", so 0 and 1 are its only meaningful values.
Unlike SADDO_CARRY/SSUBO_CARRY it does not fall back to
getBooleanContents for wider types. The matched `and` is bitwise against
a 0/1 setcc, so only bit 0 of carry_in reaches carry_out and nothing
else constrains it; a carry_in with any other bit set is outside the
operand's contract and miscompiles.
Require carry_in to be known 0/1. Check known bits rather than look for
an `and carry_in, 1`: only bit 0 is demanded inside the `and`, so such a
mask is usually folded away before this combine runs. An i1 carry_in,
which is what a real borrow chain produces, passes trivially.
Fixes #222839.

[lldb] Fix library step-in when the binary is linked with MOLD (#178695)
The mold linker adds a function symbol to the symbol table (.symtab) for
every shared library exported function.
So if we try to step into a library, lldb will fail because the symbol
at the address is not a trampline function.
Example:
```cpp
// lib.c
int lib_add(int a, int b);
```
when we link the library to an executable, mold will create the normal
trampoline functions in the .plt section but add an extra symbol in
symbol table `lib_add$plt`.

When the initializer of a constant needs relocations, the constant

This change
- sets the relocation model for z/OS to `DynamicNoPIC`, which better
fits the relocation handling than `Static`, and
- treats section kind `ReadOnlyWithRel` like a variable.

[AMDGPU][MC] Diagnose bf16 inline constants without op_sel in the ass… (#223035)
…embler
GFX1250 generates a bf16 inline constant in the high half of the
corresponding fp32 inline constant. The VOP1 bf16 opcodes therefore only
read it correctly in the VOP3 encoding with op_sel[0] set:
v_cvt_f32_bf16, v_rcp_bf16, v_sqrt_bf16, v_rsq_bf16, v_log_bf16,
v_exp_bf16, v_sin_bf16, v_cos_bf16 and v_tanh_bf16.
Codegen has applied this workaround since 57a9c4f939e5, but hand-written
assembly and inline asm had no protection at all and silently assembled
to instructions that read the wrong half. Reject those forms in the
assembler.
Only single-source bf16 opcodes are affected. Multi-source and packed
bf16 instructions such as v_fma_mix*_bf16, which also have a scalar bf16
src0, are explicitly excluded.
GFX1310 has the same FeatureBF16InlineConstFromUpperFP32 behaviour, so
the gfx1250 and gfx13 MC tests are updated together.

[CIR] Accept a union covered only by a bit-field's declared type (#222108)
The size of a union is calculated by its largest member. When that
member is a bit-field, the unit storing it can be narrower than the type
it was declared with, and it is the declared type that accounts for the
union's bytes. BitFieldType gains a query for that declared type, and
the x86_64 union rule reads it rather than the stored size, so `union {
int x : 3; }` and `union { int x : 3; char c; }` now both pass as i32.
A union larger than one eightbyte still needs a member covering it
outright, since the coerce basis skips the entry carrying the
declaration.

[AMDGPU] Make custom AsmParser matchers alignment aware (#221988)
Currently custom matchers accept registers belonging to unaligned classes, leaving the alignment check and its diagnostic to validateVGPRAlign. The problem is that validateVGPRAlign does not account for the operand register class, which may have a different alignment requirement on mixed-alignment targets.
The fix is to add a custom matcher that resolves the operand's `_AlignTarget` class via HwMode and uses that resolved class to accept a register. The drawback is that this changes the diagnostic from the more specific "error: invalid register class: vgpr tuples must be 64 bit aligned" to the generic "error: invalid operand for instruction" — but keeping the specific one doesn't seem worth the effort.
This commit converts the input-mods and DP-ALU DPP matchers. The no-modifier reg-or-inline operands come next. validateVGPRAlign stays as a catch-all until every operand is converted.

[mlir][NFC] Prune unused copyArrayRefInto template (#222365)
`copyArrayRefInto` has internal linkage, so it is only reachable from
MLIRContext.cpp, and it has no callers there. It is the only mention of
the name in the MLIR tree.
An unused internal-linkage template fires -Wunused-template. That
warning is not in -Wall on main today, having been reverted by
8710728e0418, but it did ship enabled in clang 23.1.0, so building MLIR
with that released compiler under -Werror fails here:
mlir/lib/IR/MLIRContext.cpp:379:20: error: unused function template
'copyArrayRefInto' [-Werror,-Wunused-template]
This is the same deletion as one hunk of #221480, which cleans up the
same warning across 21 MLIR files and is still open. Landing that PR is
the better outcome; this is split out only because the file blocks a
release/23.x build today.

[OpenMP] Remove the LocationDescription constructor that dropped the location. (#221949)
LocationDescription had an implicit conversion from a bare insertion
point, so `ompBuilder->emitSomething(someInsertPoint, ...)` compiled
happily and silently produced an empty debug location. Because
updateToLocation() installs the location unconditionally, this was worse
than a missing assignment: it cleared whatever the builder was carrying,
and the emitted runtime call ended up with no !dbg. On the device those
calls are inlinable, so the verifier rejects them once the runtime
carries debug info -- which is how this kept turning up as bug reports
rather than as anything visible at the callsite.
With the callers in OMPIRBuilder, OpenMPOpt, the MLIR translation and
clang all converted, the constructor can go, and the compiler will now
refuse the shape that caused the problem. Callers have to say which
location they mean: pass the IRBuilder to take its current one, or spell
out the insertion point and location as a pair.

[OpenMP][OMPD] Load `libompd` with LLVM dynamic lib (#222455)
OMPD loads `libompd.so` through a small helper, but that helper still
uses `dlopen/dlsym` under the hood. We have already laid the foundation
by making libraries load behind helpers in the current state; this one
is simply a cleanup that moves helpers to LLVM's loader, which is LLVM's
standard.
The current state has few issues:
1: Still tied to Unix-style APIs.
2: Windows support has to separately deal with loader differences.
3: Future shared-lib work would need more loader changes later.
This patch keeps the same OMPD API and call sites, but replaces the
implementation with LLVM's DynamicLibrary. Error handling remains
unchanged.

[RISCV] Don't use VL node when lowering scalable mask reductions (#223392)
Using ISD::XOR gives us the generic not (setcc cc) -> setcc inverse-cc
combine. With the VL optimizer we still get the same VL propagated.
Restricted to just scalable vectors since some fixed vector patterns
break without the VL node.
The VP test doesn't improve because
1) VP reductions get legalized during regular op legalization, not
vector legalization
2) so generic DAGCombines don't get a chance to run before the
(splat_vector 1) is legalized to vmset_vl.
We can fix this by keeping the (splat_vector 1) legal, but this is left
to another PR.

[flang] Promote scalar slots reached through fir.convert and fir.declare (#219314)
Neither `fir.declare` nor `fir.convert` implements
`PromotableAliaserInterface`, so mem2reg does not see accesses made
through them as touching the slot behind. A cast anywhere in the chain
blocks promotion outright, even when it only changes the flavor of a
reference to the same scalar. So a scalar slot reached as `memref.alloca
-> fir.convert -> fir.declare -> fir.convert -> store/load` stays in
memory today.
This patch implements `PromotableAliaserInterface` for both operations.
mem2reg collects defining blocks from the alias map, so writes through a
`fir.declare` are now seen and the single-block restriction from
https://github.com/llvm/llvm-project/pull/182933 is no longer needed. An
operation reports an alias only when it carries the pointee through
unchanged, so that the default value projections of the interface apply;
for a `fir.convert` that limits it to a reference or a rank-0 memref of
a simple scalar with an identity layout and no memory space, and never
when either side is volatile.
A `fir.convert` additionally requires every read of the slot to be
preceded, in its own block, by a write. A read that no write reaches
takes the default value of the allocation, which is `fir.undefined` for
`fir.alloca` but poison for the memref allocations a cast can reach.
Without this requirement, promoting through a cast would change what
reading an uninitialized variable produces.

57a9c4f939e5 made codegen emit the VOP3 encoding with op_sel[0] set when
a bf16 inline constant reaches one of the single-source VOP1 bf16
opcodes, because the hardware generates the constant in the high half of
the corresponding fp32 inline constant.
GFX1310 has the same FeatureBF16InlineConstFromUpperFP32 behaviour.
Mirror the enabled gfx1250 SelectionDAG RUN lines with gfx1310 ones so
the workaround is covered there too. Test-only change, no functional
change.

[libc][bazel] Expose public inline memory headers and generic/builtin.h in string_memory_utils (#223439)
Following commit 041300fa05151b3819478f33daa4384922b4b74e (#192079),
`libc/src/__support/FPUtil/aarch64/fenv_darwin_impl.h` includes
`src/string/memory_utils/inline_memcpy.h`.
In the Bazel overlay, `string_memory_utils` declared inline memory
dispatcher headers under `textual_hdrs` rather than `hdrs`, preventing
transitive consumers from accessing them. Additionally,
`src/string/memory_utils/generic/builtin.h` was missing from
`string_memory_utils`.
This patch:
- Moves public inline memory headers from `textual_hdrs` to `hdrs` in
`string_memory_utils`:
- `src/string/memory_utils/inline_bcmp.h`
- `src/string/memory_utils/inline_bzero.h`
- `src/string/memory_utils/inline_memcmp.h`
- `src/string/memory_utils/inline_memcpy.h`
- `src/string/memory_utils/inline_memmem.h`
- `src/string/memory_utils/inline_memmove.h`
- `src/string/memory_utils/inline_memset.h`
- `src/string/memory_utils/inline_strcmp.h`
- Adds `src/string/memory_utils/generic/builtin.h` to `textual_hdrs`.

[flang][cuda] do not honor -fstack-arrays in device procedures (#223040)
The device stack is far smaller than the host one, so an automatic array
that fits the host stack easily overflows it. With `-fstack-arrays`
(implied by `-Ofast`) automatic arrays in CUDA Fortran `global` and
`device` procedures were kept on the device stack and overflowed it at
runtime.
Lowering now records a `fir.allocation_policy` with `stack_arrays`
disabled on those procedures, and `getAllocationPolicy` honors a policy
on the enclosing function instead of only the one on the module. The
size based part of the policy is unchanged, so small constant size
arrays still go on the device stack. Host procedures, including the host
copy of `attributes(host,device)`, are unaffected.

old usage a hard error.
This commit adds `rocdl.xnack` and `rocdl.sramecc` module attributes
to the discardable attribute list the ROCDL dialect defines in order

Omitting them means to leave these modifiers at
their default "either" state, which isn't the same as setting them to
false.

[CIR] Accept `_BitInt` wider than 128 bits in x86_64 callconv lowering (#223069)
With byval in place, a `_BitInt` wider than 128 bits can classify
Indirect and flow through the same byval/sret path as an oversized
aggregate.
That turned up a latent bug, fixed here since it was not reachable or
testable before: the byval/sret pointee type was using the raw declared
width instead of the padded storage width (e.g. `i200` instead of
`i256`), understating the copy size.
Widths whose padded storage integer is not a whole number of 16 bytes,
such as `_BitInt(129)` at `i192`, still have no in-memory layout in CIR
and now reach that gap through the byval and sret pointee instead of
through the classifier. They stay NYI.
Drop the opt-out from the three CIR lit tests gated on this.

[lldb] Speed up `SBValue::CreateValueFromExpression` by using DIL (#222192)
The goal of this patch is to significantly speed up the evaluation of
expressions in the SB API call `SBValue::CreateValueFromExpression`. DIL
is called first and attempts to evaluate the expression, and if it
fails, the function falls back to full expression evaluator. The call to
DIL can be disabled by setting
`target.experimental.use-DIL-for-creating-values` to `false`.
The need for this change comes from `SBValue::CreateValueFromExpression`
often being used in Python data formatters for other projects, where
running the full expression evaluator even for some simple expression
dramatically slows down the entire formatter. The performance overhead
if DIL fails to evaluate the expression is only marginal.

[lldb] Fix DIL losing StackFrame context after casting to pointer (#222386)
When casting to pointer type, `CreateValueObjectFromAddress` is called
with Target context only, so the resulting `ValueObject` doesn't have
StackFrame context anymore, which can cause problems when it is returned
as a final result from DIL. This patch fixes the issue.

[Flang][HLFIR] Bail out of EOSHIFT simplification for polymorphic arrays (#223118)
Consider the following code

ARRAY=b1,DIM=1, BOUNDARY=boundVal))
type is (integer)
print *, name1
print *, shape(name1)
class default
ERROR STOP(1_4)
end select
end
```
it passed at `-O0` but failed at `-O3` as
```
argumentKeyword002.f":38:5): error: 'fir.result' op types mismatch between result op and its parent
error: Lowering to LLVM IR failed
```
The reason is that the `SimplifyHLFIRIntrinsics` is trying to inline
`EOSHIFT` of a `CLASS(*)` array as an `hlfir.elemental` produces a
`fir.if` with mismatched types on the branches (e.g., `!fir.class<none>`
vs. pointer-qualified `!fir.class<!fir.ptr<none>>`).
By looking at the code, we currently bail-out derived type array so it
falls back to the runtime code. Polymorphic array should be bailed-out
also for now and handled with derived type together in the future.

[libc] Restrict sysconf/confstr to full-build mode. (#223103)
`sysconf` (and its sibling `confstr`) from `<unistd.h>` return some
values specific to the kernel/environment,
and some values specific to the system library (e.g. features available
in system library's pthread implementation).
Using LLVM-libc sysconf in overlay mode is inherently problematic - we
don't know what features host libc has,
and trying to reverse-engineer it would be brittle. Since we include
host libc's `<unistd.h>`, we can't even know in
advance what `_SC_` values or what macros would be available there, so
the portable implementation of `sysconf`
will be convoluted, and there's little benefits to it anyway.
Conversely, making sure that our `sysconf` implementation only compiles
against LLVM-libc's own headers will allow
us to precisely handle macro / features that we know are available /
supported.
Migrate four tests from sys/mman.h to use `getpagesize()` function
instead of generic `sysconf` to ensure those
tests won't be auto-excluded in overlay mode.
Remove the workarounds for overlay-mode added to sysconf(), since those
are no longer needed.

[SandboxVec][VecUtils][NFC] BndlRef helper class (#223074)
During debugging we need to be able to easily print a bundle of
instructions or values. Up until now we would use VecUtils::dump(Bndl).
But a much nicer API would be Bndl.dump().
To support such an API this patch is introducing BndlRef, a subclass of
ArrayRef with the additional feature of supporting print(OS) and dump()
for Value and Instruction contents.

[TableGen] Expose remapRegClassByHwMode() helper in AsmMatcher
This is useful to map from a ByHwMode MCK_* value to the actual resolved
MCK_* type. This is needed for #177073 where we would otherwise have to
add the manual logic to do this remapping (which is the approach I
previously used). Move RegClassByHwModeMatchTable to file scope and
provide a remapRegClassByHwMode() helper function in the generated
AsmMatcher. Currently only used for RISC-V, but I assume other targets
could also make use of this in the future. But even if not, I think it's
cleaner to have this as a helper rather than an inline array inside the
matcher function.
This change was created with the help of AI tools.

[Support] Make formatted_raw_ostream::has_colors() delegate to the wrapped stream (#223092)
Without this override, has_colors() falls back to is_displayed(), which
isn't always expected to give the same answer as the underlying stream's
has_colors().
This also fixes a compile-time regression when the underlying stream is
a raw_fd_ostream: raw_fd_ostream::has_colors() memoizes its result, but
without this override that memoization was bypassed in favor of the
uncached is_displayed(), issuing an isatty() syscall on every call.
#202441 is what surfaced this, by adding a has_colors() call to
TextDiagnostic's per-character hot loop.

[DebugInfo][NVPTX]Avoid adding per line .loc in the ptx output for the compiler-generated inline ptx block. (#222764)
`NVPTXAsmPrinter::emitInlineAsm` splits the asm string on newlines and
emits a `.loc` per PTX instruction, incrementing the source line for
every physical line of the block. For a compiler-generated block, this
attributes the generated code to unrelated source lines, and for a long
enough block, to lines beyond the end of the file.
A DSL frontend can lower one source-level construct -- an assert, a
barrier, an intrinsic -- into a single block of inline PTX. The
individual lines of that block have no source correspondence; they all
belong to the one construct.
This change adds a check for isImplicitCode on the inline asm's
DILocation and skips the per-line path when it is set.

[compiler-rt] Add AMDGPU Device UndefinedBehaviorSanitizer runtime (#219972)
Summary:
This adds support for full UBSan on the AMDGPU target. The GPU build of
`compiler-rt` will now build `libclang_rt.ubsan_standalone.a` and the
host build will now provide `libclang_rt.ubsan_offload.a` for the
host-side formatting.
The **core** approach is to simply gather arguments from the device and
replay them on the host. The RPC interface acts as the narrow shim to
pass data between the CPU and GPU.
The changes to the core runtime are kept minimal, only exposing a few
needed hooks to re-run and symbolize reports coming from an external
caller. The device archive is a side-library which will only be present
for GPU offloading builds.
Putting this in `compiler-rt` via interceptors avoids an ABI edge
between many consumers, (OpenMP, HIP, Pytorch, etc). The runtime code is
specifically built around HSA, but as more features grow this could be
refactored into a shim layer for SPIR-V / CUDA and factored out to a
common sanitizer utility. Leaving that as future work.

[Clang] Enable UBSan for AMDGPU device offload (#219973)
Summary:
This enables the device UBSan runtime for AMDGPU devices. Primarily this
required modifications to the `addSanitizerRuntime` interface so we can
query the compilation's offload status. Also need to forward it through
the linker wrapper interface. Works on all AMDGPU offload, slight hacks
around the other targets as they do not advertise sanitizer
runtimes properly.
This is linked in via a new `-u __ubsan_offload_init` hook to pull
in the side library. This is standard behavior and keeps the core logic
mostly unchanged and re-used.

[libc] Don't declare vector_size types that cannot be compiled (#221119)
On machines where [[gnu::vector_size(N)]] types are generally
supported, each given N can only be used when the corresponding
CPU features are enabled by the particular -m switches et al.
Don't make any use of a type that's not enabled for native
register use according to the predefines reflecting -m switches.
Even inline and template functions that wind up being unused can
make the compiler give errors about the use of a type whose use
is disabled for ABI or ISA configuration reasons.

[RegAllocEvictionAdvisor] Make the local reassign option more useful (#223115)
Prior to this patch the CLI option for the local reassignment heuristic
could only force enabling the local reassignment heuristic. In other
words, there was no way to disable the heuristic if the target hook said
otherwise, which defeated the purpose of the option.
Fix this by ensuring that when the option is set it takes precedence
over the target hook. This makes experimenting with the local
reassignment heuristic much easier.
The patch is NFC unless you set the option.

[libc][baremetal][BigInt] fix codegen issue for UInt128 (#220389)
`BigInt::operator*` always computes the full 2N-word product (`ful_mul`,
i.e. `multiword::multiply_with_carry`) and then truncates. In order to
scalarize the process to generate efficient code, the loop needs to be
fully unrolled, which fails on 32-bit targets for int128 due to LLVM's
default threshold. This patch adjust the hint to allow int128 to be
unrolled while gating larger integers away.
### 64-bit targets: roughly okay
aarch64 is byte-identical before/after; x86-64 gets one `mov` shorter.
After the patch, 128×128→128 (lo/hi in memory):
```asm
; aarch64 ; x86-64
ldp x8, x12, [x0] movq (%rdi), %r9
ldp x9, x10, [x1] movq (%rsi), %r8
mul x10, x10, x8 movq %r8, %rax
mul x11, x9, x8 mulq %r9
umulh x8, x9, x8 imulq 8(%rsi), %r9
madd x9, x9, x12, x10 imulq 8(%rdi), %r8
add x8, x9, x8 addq %r9, %r8
stp x11, x8, [x2] addq %rdx, %r8
ret ...
```
### 32-bit targets (e.g. cortex-m85): badly bloated
A 64-byte stack frame, carry selection through IT blocks, and a call
into an outlined `ful_mul`. Kernel is the folded multiply (`lo ^ hi` of
the `UInt<128>` product):
```asm
; before ; after
sub sp, #64 umull r12, lr, r2, r0
mov.w r12, #0 umull r2, r4, r2, r1
strd r12, r12, [sp, #24] umull r0, r5, r3, r0
orrs.w lr, r0, r1 umaal r4, r5, r3, r1
it ne adds.w r1, lr, r2
strdne r0, r1, [sp, #16] adcs r2, r4, #0
... (5 more stores) adc r3, r5, #0
bl BigInt<128>::ful_mul adds r0, r0, r1
ldm r3, {r0, r1, r2, r3} adcs r2, r2, #0
eors r1, r3 adc r1, r3, #0
eors r0, r2 eors r1, r0
add sp, #64 eor.w r0, r2, r12
```
llvm-mca (cortex-m85): **114 → 11 cycles** per folded multiply.
### Benchmarks
| environment | before | after | speedup |
|---|---|---|---|
| EK-RA8M2 (Cortex-M85 r1p1, DWT cycle counter, I-cache on) | 250
cyc/mul | 20 cyc/mul | 12.5× |
| wasm32 under wasmer 7.3, `-U__SIZEOF_INT128__` (see notes) | 0.70 s /
100M muls | 0.28 s | 2.5× |
Bench kernel (dependent chain, identical results before/after):
```cpp
using B = LIBC_NAMESPACE::BigInt<128, false, uint64_t>;
B x = (B(a) << 64) | B(~a);
B y = (B(b) << 64) | B(~b);
for (int i = 0; i < n; i++) {
x = x * y;
y.val[0] ^= x.val[1];
}
return x.val[0] ^ x.val[1];
```
### Carry builtin dispatch fix
Additionally, fix a typo in the `add_with_carry` / `sub_with_borrow`
builtin dispatch: the `#if`/`#elif` chain over `__has_builtin`.
### Notes
1. Another workaround for such targets is to force-enable native 128-bit
integers (clang's `-fforce-enable-int128`)
2. The wasm number above is benched with 128-bit integers forcibly
disabled (`-U__SIZEOF_INT128__`), just to check its effect.

[VPlan] Use VPlan-based costs for pointer inductions. (#223394)
Drop the last legacy induction fallback in precomputeCosts, completing
the migration of induction costs to be VPlan-based.
The fallback charged the cost of the IV phi. The cost of the GEP
incrementing the IV was considered free.
VPWidenPointerInduction::computeCost now charges the cost of the phi
plus a TODO to also consider cost of the increment and wide pointer add.
For scalarized pointer inductions, we do not charge any cost for the
scalar GEPs, like before, assuming they can be folded into the
addressing mode.
Test changes are due to the fact that scalarized pointer inductions do
not require an extra phi (on most platforms, phis are considered free,
so not many tests are impacted).

Revert "[clang][NFC] Refactor flag enum caching (#210632)" (#223244)
This reverts commit f5437c4d4f2e9920614d856158d9683d650acffa.
That change moved population of Sema::FlagBitsCache out of
IsValueInFlagEnum and into ActOnEnumBody, and turned the lookup into
DenseMap::at(). ActOnEnumBody only runs for enum definitions that are
parsed in the current translation unit, so an EnumDecl deserialized from
a PCH never gets a cache entry and DenseMap::at() dereferences end(),
crashing clang in builds without assertions.
A switch over any enum with the flag_enum attribute that is defined in a
PCH is enough to reproduce. The crash cannot be avoided by turning the
switch diagnostics off: unlike DiagnoseAssignmentEnum, the switch path
in ActOnFinishSwitchStmt has no Diags.isIgnored() guard, because it runs
the analysis regardless in order to record the result in the AST.
In practice this breaks any translation unit that instantiates
std::basic_regex<char> while <regex> is in a PCH, since libstdc++ marks
std::regex_constants::syntax_option_type as a flag enum and
_Compiler<_TraitsT>::_S_validate switches over it. That became reachable
with 44b33260a38c, which made clang honor the gnu:: spelling of the
attribute, but the underlying defect is the one reverted here.
Add a regression test for the PCH path. It checks the computed flag bits
rather than just the absence of a crash, so that a silently empty cache
entry fails the test instead of passing it.

[mlir][AMDGPU][NFC] Pre-commit tests for incorrect version checks (#220104)
There'll be a refactoring from `amdgpu::Chipset` to
`ROCDL::TargetInfo`, thus also moving from chip version checks to
features checks. This commit adds tests for incorrect lowerings that
were allowed by the current code.
- gfx90c is >= gfx90a but stil needs atomic emulation (it doesn't
have buffer fmax and so on).
- gfx90c is also >= gfx90a but has no barrier back-off, so it needs
the inline asm workaround around `s_barrier` that it isn't getting
- gfx908 doesn't have a packed fp16 atomic add but we thought it did
- gfx950 is mistakenly allowing xf32 MFMAs
- gfx1200 is allowing permlane_swap instructions that it doesn't have
- gfx11.7 should be allowing OCP FP8 conversions but isn't on the list
This also cleans up some redundant tests with a --check-prefixes
AI disclosure: Claude found these and wrote the tests.

Combined `parallel loop firstprivate` currently puts firstprivate only

that one copy when v is updated. Attach also an implicit loop
firstprivate whose varPtr is the remapped compute copy.
Attach only when: 1) the loop is combined parallel loop, 2) and
independent (the default; not seq/auto), and 3) the firstprivate is an
OpenACC scalar. Arrays, sections, derived/character/boxed types, serial
loop, and non-combined parallel+loop stay compute-only.

[Analysis] Fix GCC warnings on ABI annotations (#222286)
The GCC build is cluttered by type attribute warnings on some header
files:
```
llvm/include/llvm/Analysis/RegionInfo.h:898:41: warning: type attributes ignored after type is already defined [-Wattributes]
898 | extern template class LLVM_TEMPLATE_ABI RegionBase<RegionTraits<Function>>;
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
```
The type attributes originate from PR #199019. The warnings occur
because the
specific template instantiation is triggered implicitly earlier, without
the
type attribute. This can be fixed by placing the extern template
declaration
before the implicit use.
Also, the implementation files were using `LLVM_TEMPLATE_ABI` instead of
`LLVM_EXPORT_TEMPLATE`, contrary to the guidance in
`llvm/docs/InterfaceExportAnnotations.rst` ("Explicitly Instantiated
Template
Classes"). This would trigger the same type of GCC warning in the
implementation file.

CodeGen: Clear physreg ranges after SplitCriticalEdge (#223172)
After critical edge spliting replaces a terminator, clear referenced
physreg ranges. The block's terminators may be replaced, and may
reference physical registers (e.g. WebAssebly's ARGUMENTS. When
LiveIntervals is available, repairIntervalsInRange only repairs virtual
registers, so the tracked physreg units were stale.
It feels like a bug that repairIntervalsInRange doesn't touch physregs,
but I've left that for a future change.

[DWARF] Add DW_MSPACE_LLVM_* memory space encodings (#220766)
DW_AT_LLVM_memory_space is already defined in Dwarf.def, and the memory
space encodings it takes are already specified in
docs/AMDGPUDwarfExtensionsForHeterogeneousDebugging.rst, but the values
had no names in the source, so llvm-dwarfdump printed the attribute as a
bare integer.
Add the encodings via a HANDLE_DW_MSPACE macro alongside the existing
HANDLE_DW_ASPACE, define the MemorySpace enum, and add MemorySpaceString
and getMemorySpace. AttributeValueString then resolves the attribute, so
no changes are needed in the DWARF consumers themselves.
Unlike address spaces, memory space encodings are target-independent, so
MemorySpaceString takes no triple.

[HLSL] Add CustomTypeChecking and improve sema for texture builtins (#221060)
This PR makes the texture builtins (for load, sample, gather) use
CustomTypeChecking, and adds additional semantic checks for them to make
them more strict and conform with the way sema checks are done for other
builtins.
The main benefit of CustomTypeChecking is preventing
DefaultArgumentPromotion from occurring due to the builtins being
declared `void(...)`; primarily, the promotion of float/half to double
is undesirable.
Floating-point scalar operands in codegen (`CGHLSLBuiltins.cpp`) for
these builtins always had a check and cast of the form `if
(Op->getType() != FloatTy) Op = CreateFPCast(Op, FloatTy);` to
compensate for that, which looked like a code smell to me.
The DefaultArgumentPromotion also affected diagnostics, which would
report the promoted type (double) instead of the type the user provided
(float) (e.g., https://hlsl.godbolt.org/z/Yec3dKh14). These diagnostics
were not exercised before, and this PR adds tests to exercise them.
Sema checks for the texture builtin args have also been made more strict
and rewritten to be like sema for other builtins, using
`CheckArgTypeMatches` rather than only checking vector element count.
Finally, in preparation for 1D texture types, the sema for texture
builtins now allow scalar args where it is relevant.

[clang-repl] Fix FindMangledNameSymbol test on Darwin/arm64e (#223410)
Fix the FindMangledNameSymbol unit test by comparing values as
llvm::orc::ExecutorAddrs.
This test was using comparing a pointer cast to uintptr_t and the result
of an ExecutorAddr::getValue call, but those can be different on
Darwin/arm64e due to pointer authentication. Comparing as ExecutorAddr
values eliminates this difference (pointer authentication bits are
stripped from both sides).

This PR implements the Texture1D type and its variants: RWTexture1D,
Texture1DArray, and RWTexture1DArray.
It also implements the codegen for the texture builtins so that they can
handle scalars where they otherwise always assumed a vector before the
existence of 1D textures.

[CIR] Fix 'isConstant' calc when looking at an incomplete type (#223444)
This popped up in a benchmark. Classic codegen ALWAYS sets this as
'excludeCtor'/'excludeDtor', but CIR tried 'harder' to get this right.
However, with an incomplete type, we can't actually look into it to see
if it has any mutable members, so determining 'constness' isn't
possible.
We could PROBABLY do better with enums since I would assume they can be
constant most of the time, but we fall-back to classic-codegen's
behavior here instead: which marks it as non-const.
Thanks to 'trying harder' than classic codegen as mentioned above, there
IS a slight LLVM-IR difference, but for the better.
Also note: Claude helped me with the tests.

[BOLT][AArch64] Make Android instrumentation runtime fail safe (#223110)
Profiling failure in BOLT instrumentation runtime should not kill the
host app on Android. Under `ANDROID_AARCH64`, we now handle failures
in instrumentation setup, memory allocation, hash table operations,
data dumping, opening profile output file, zero-counter binary, etc..
Since the first failure, we will disable profiling and directly return
from various instrumentation entry points, instead of assert/exit.
Only for Android AArch64; the behavior is unchanged otherwise.

[BOLT] Prevent missing ExternalBranch validation (#221927)
#165406 introduced validation to check whether a branch target is a
valid instruction to detect corrupted CFGs. However, as described in
[165406#discussion](https://github.com/llvm/llvm-project/pull/165406#discussion_r2601459105),
it can miss validations when a function contains multiple invalid
ExternalBranches.
Therefore, this patch introduces a branch-level set to prevent duplicate
validations while ensuring no branches are missed.

The fold combines:

The fold handles both orderings. I implemented tests for this fold in

so a target with Y enabled and no explicit -target-abi

l64pc128(d).
This adds explicit non-RVY ABIs to two tests since otherwise those would
hit the assertion that the ABI is not supported yet. As the ABI does not
matter for these tests, we can safely use the non-RVY ones.

dominated by InstCombine (~68s) and greedy register allocation (~71s).
Recently, LLVM_ATTRIBUTE_MINSIZE was added to optimize for size, but
MSan
instrumentation still inflates the function enough to trigger severe
slowdowns in the backend.
Mark the constructor with optnone under LLVM_MEMORY_SANITIZER_BUILD to
skip
expensive optimization and register allocation passes, bringing
compilation
time under MSan down from 3m38s to ~30s.
This is done to fix
http://lab.llvm.org/buildbot/#/builders/aarch64-linux-msan,
though it is very slow on x86_64 as well.

[ProfileData] Bound binary sample profile primitive reads (#215476)
Fix pre-existing latent memory-safety issues that could cause
out-of-bounds reads or invalid pointer arithmetic on malformed,
truncated, or non-null-terminated buffers:
* unbounded ULEB128 decoding in readNumber() and Raw/Ext format probes;
* unbounded terminator searches in readString() and GCC format
detection;
* unsafe bounds checking in readUnencodedNumber().
Use bounded decoding, memchr, overflow-safe size checks, and typed
ULEB128 errors. Preserve the existing decodeULEB128 interface and avoid
test-only ABI exports.
Add functional and guard-page tests that detect boundary regressions
without requiring sanitizers.

[RISCV] Improve the earlyclobber constraint for vector index load. (#223565)
When the data EEW is smaller than the index EEW, the destination may
overlap the index operand as long as the overlap is in the
lowest-numbered part of the index register group. If the index EMUL is
no larger than 1 then both operands are a single register, so any
overlap is necessarily the lowest-numbered part and no constraint is
needed.

[MergeFunc] Fix poison flag merging for varargs functions (#223347)
This is a followup to https://github.com/llvm/llvm-project/pull/220015.
writeThunkOrAliasIfNeeded() has an early exit for the case where none of
erase/thunk/alias apply, and we failed to merge the poison flags in that
case. I've opted to fix this by moving the annotation merging logic out
of writeThunkOrAliasIfNeeded() entirely, because I don't think it
logically fits there (it's not related to thunk/alias creation at all).
This is the minimal fix to address the miscompile. There is a potential
larger change we could make here, which is to avoid "merging" the
functions in this case in the first place. We don't actually merge the
functions here, but just rewrite all uses to one of them. This seems
kind of dubious to me, though I could see an argument that this can
still be beneficial in conjunction with --gc-sections (i.e. linker-level
dead function elimination).

[X86] Fix FP `stackifier` crash on invalid `x87` inline `asm` constraints (#221881)
Fixes #149371
When an x87 inline asm uses the stack registers in a layout the FP
stackifier can't model, for example an input tied to `st(1)` while
`st(0)` and `st(1)` are both outputs, the pass reports "fixed input regs
must be last on the x87 stack" and then keeps going as if nothing
happened. It simulates the pops and pushes with counts taken from masks
it has just found to be non-contiguous, so the input never leaves the
stack model and the same register gets pushed again as an output. The
model now holds a duplicate entry, and the next `adjustLiveRegs` trips
"Live count mismatch". The odd `R0` constraint in the report isn't the
culprit, by the way; it resolves to a plain integer register and leaves
the tied `1` as the only x87 input.
Once any of these errors has been reported, the asm is no longer
simulated. The pass pops the inputs the asm kills and pushes its
outputs, which keeps the stack model consistent with what the register
allocator expects, and then lets compilation fail normally with the
diagnostic. The old trick of rounding the output mask up to a contiguous
range is gone too, since it only papered over one of the four cases. The
new test covers all four diagnostics plus the two-asm sequence that used
to assert.
LLM tools were used for this contribution. I've reviewed, built, and
tested the change myself before pushing to GitHub.

The function `shouldJustCallCheckers` introduced recently in

returns false for statement kinds where it is inappropriate to call the
PreStmt and PostStmt checkers in the "normal" pattern.
Unreachable statement kinds (e.g. control flow statements that never
appear as non-terminator statements in a CFGBlock) were covered by
explicit cases in `shouldJustCallCheckers`, but this was needless
complexity, so this commit removes it. These statement kinds run into
`llvm_unreachable` in `ExprEngine::Visit`, so the behavior of
`shouldJustCallCheckers` is completely inconsequential.

Add coverage for intrinsic and sitofp/uitofp fixed-point conversions.
Select scalar FP/SIMD-register conversion forms when a fixed-point
int-to-fp conversion uses a value extracted from a SIMD vector.
This avoids moving the reduction result through a GPR before
converting to floating point.

Same as https://github.com/llvm/llvm-project/pull/220007 but for
getMulExpr:
add option to pass SCEVUse-specific flags to getMulExpr and propagate
them through, if valid conservatively. That is, the final expression
multiples the same operands (potentially in different order). For
example, it is not valid to propagate the use flags if other
(sub-)expressions have been inlined.
It also includes a few mechanical changes, to update users that still
expected const SCEV *.

[AArch64] Promote unpacked SVE f16/bf16 compressstores 32/64-bit (#222321)
To support compressstore for unpacked 16-bit SVE floats (e.g., nxv2f16),
we need to expand the compressstore before type legalization. If we
expand after type legalization the `VECTOR_COMPRESS` node inserted won't
be promoted to a 32/64-bit element size (which means we'd have to
duplicate some type legalization in the lowering).

higher level optimizations come through and restructure the code, say by
removing a load/store, you no longer have the behaviour TySan would pick

`getDependenceDistanceStrideAndSize` already requires non-zero strides
in the same direction, each a multiple of the corresponding type's

either access. With equal starting addresses, accesses from different

[AMDGPU] Scale the frame register in place when lowering scalar frame indices (#221972)
Lowering a scalar frame index needs a scalar temporary, and under full
SGPR pressure the scavenger emergency-spills instead, which flips EXEC
with `s_not_b64` and clobbers SCC, With SCC live the spill builder gives
up with `error: unhandled SGPR spill to memory`.
Use `FrameReg` itself as the temporary and restore it after the
instruction with `S_MUL_I32`, which unlike `S_LSHL_B32` does not write
SCC, folding a non-zero offset back through an
`S_ADDC_U32`/`S_BITCMP1_B32`/`S_BITSET0_B32` sequence when SCC is still
live.
This is restricted to SALU instructions with a single frame index that
do not otherwise touch `FrameReg`; everything else keeps the existing
path, including the emergency spill.

A CycleStmt at the end of the body of its own DoConstruct is a no-op:

Branch analysis nonetheless marks the DoConstruct unstructured, which
costs the structured form of the loop and the induction variable
semantics that later passes rely on.
Delete such a CycleStmt in the PFT. The statement must be unlabeled, so
that it is not itself a branch target, and it must name either no
construct or this one.

clang/ARM: Derive -pg mcount name from the triple environment (#220822)
For a glibc/gnueabi ARM and AArch64 targets, GCC's -pg instrumentation
always calls __gnu_mcount_nc (with the caller pushing LR, per the "nc"
no-LR-clobber ABI). clang only produced this when -meabi=gnu was passed
explicitly; a separate gnueabi triple wrongly called plain "mcount".
On ARM, glibc's EABI profiling entry point is __gnu_mcount_nc
(sysdeps/arm/arm-mcount.S, exported since GLIBC_2.8). It does provide
plain mcount/_mcount, but only as a legacy APCS compat alias
(__mcount_arm_compat, gated on GCC_COMPAT(4,3)/SHLIB_COMPAT)
that reads an APCS frame-pointer record rather than following the EABI push-LR
convention. Calling it from EABI -pg code is thus an ABI mismatch, not the intended
entry point.
Derive the GNU-vs-plain mcount name from the triple environment in
addition to the explicit -meabi=gnu, so a gnueabi target gets the correct
__gnu_mcount_nc call by default, matching GCC:
push {lr}

[SelectionDAG] Soft promote the element operand of INSERT_VECTOR_ELT (#223612)
When f16/bf16 is soft promoted but a vector of that type is legal,
INSERT_VECTOR_ELT is left with a soft promoted i16 element operand.
SoftPromoteHalfOperand had no case for it and failed with "Do not know
how to soft promote this operator's operand!".
Legalize it like BUILD_VECTOR and the inverse EXTRACT_VECTOR_ELT:
bitcast
the vector to its integer counterpart, insert the promoted element there
and bitcast the result back. This also covers scalable vectors.
This is reachable on MIPS MSA and on RISC-V with Zvfhmin/Zvfbfmin but
without Zfhmin/Zfbfmin. X86, Hexagon and WebAssembly avoid it by custom
lowering INSERT_VECTOR_ELT on the scalar type; that still takes
precedence and can be removed separately.

LICM: Drop -licm-force-thread-model-single in favor of the module flag (#223158)
Now that the threading model is carried by the "thread-model" IR module
flag, the hidden -licm-force-thread-model-single override is redundant: a test
can select the single-threaded model by setting the module flag directly.
isThreadLocalObject reads only Module::getThreadModel.

[MLIR][Linalg] Improve morphism semantics (#222959)
As exposed on the issues linked, the linalg morphism semantics could be
improved.
This PR changes the following semantics:
* Completes support for `-linalg-morph-ops` to include contractions and
ternary elementwise.
* Adds a `-linalg-categorize-ops`, which moves both named and generic
ops to category.
* Adds the possibility of "stopping at category" for both specialization
and generalization (not accessible from command line options but used by
the new categorize / old morph-ops pass).
* Removes the morphism options structure, since it's just a Boolean
flag.
* Improve test coverage, and make sure that `-linalg-morph-ops` does the
same thing as the other options.
It does NOT:
* Change the semantics of generalization, which continues to generalize
everything.
* Change the semantics of specialization, which continues to convert to
named or category whenever possible.
There's also come cleanups for the matching of elementwise that was
simpler as a `TypeSwitch`.
Fixes #221266 and #221191

[LLVM] Add llvm.[su]mulh intrinsics. (#220293)
These intrinsics correspond to (un)signed multiply-high operations. The
motivation for introducing them is to allow more accurate costing
(particularly for vectorisation) and to simplify code generation for
chained multiply-high operations.
Together with subsequent patches to combine and cost the intrinsics,
this gives an 8% speedup on 750.sealcrypto_r on Neoverse V2.

[AArch64] Reuse SUBS results for conditional subtraction (#223391)
For C++ code such as:
uint64_t conditional_subtract(uint64_t x, uint64_t q) {
return x - (x >= q ? q : 0);
}
AArch64 currently uses three instructions for the conditional
subtraction (omitting the return):
cmp x0, x1
csel x8, x1, xzr, hs
sub x0, x0, x8
The comparison already computes x - q to set the condition flags, but
its arithmetic result is discarded. Preserve that result with SUBS and
select between it and x, reducing the sequence to two instructions:
subs x8, x0, x1
csel x0, x8, x0, hs
Apply this combine to i32 and i64 single-use selects with zero in either
arm. Keep the original flags and condition code, allowing signed,
unsigned, equality, and overflow conditions while preserving other users
of the comparison.
This gives an approximately 3% performance improvement in the
750.sealcrypto_r benchmark from SPEC CPU 2026.

Use llvm.clear_cache for __clear_cache() as well, for consistency and to

Use computeKnownBits to identify nonconstant memset lengths whose

dedicated helper foldMemSetZeroOrOneLength.
Insert a conditional branch around the memset and specialize the

pass can then replace it with a byte store, including for a
nonconstant fill value.
Do not transform wider ranges such as [0, 2].

[MSVC][Demangling] Respect MSDF_NoCallingConvention for function pointers (#209113)
The goal is to update MSVC demangling so that we control whether we
display a function pointer as `void (__cdecl *funcPtr)(void)` or `void
(*funcPtr)(void)`, by abiding by the `MSDF_NoCallingConvention` flag.
It is not a one-liner because function pointers used to use a trick
where it would unconditionally drop all the flags and pass
`OF_NoCallingConvention` to output the calling convention inside the
parentheses. In order to respect `MSDF_NoCallingConvention`, we need to
get rid of this trick.
A side effect of the trick was that OF_NoReturnType was also lost, which
is actually good because dropping the return type of a named function is
unambiguous, but dropping the return type of a function pointer loses
important information. The fix enforces that behavior explicitly.
This change can have impact for end-users who always passed
MSDF_NoCallingConvention, but I believe that this new behavior is the
one they were expecting.

Same as https://github.com/llvm/llvm-project/pull/220007 but for
getAddRecExpr:
Pass both expression and use specific flags to getAddRecExpr and
propagate the use flags, if valid conservatively. That is, the final expression
forms an AddRec with the same operands. For example, it is not valid to
propagate the use flags if other (sub-)expressions have been inlined.
It also includes a few mechanical changes, to update users that still
expected const SCEV *.

[clang][Sema] Fix false-positive -Wshadow for friend functions (#221249)
A friend function defined inline in a class body has no implicit `this`,
so a parameter with the same name as a field cannot actually shadow it.
`CheckShadow` only exempted static members and members with an explicit
object parameter, it never handled the case where the enclosing function
isn't a member function at all, which fell through to the generic
diagnostic. In this PR I extend the exemption to cover that case and
added the regression test.
In this PR, I used Claude to help navigate the codebase and explain key
functions.
Fixes #221190

[Clang] Partially reapply "Refactor instantiation of declarations within concepts" (#223311)
This partially reverts db65ace07
It turns out that we cannot simply reuse the instantiated declarations
on stack, and our LIS is lack of ability of distinguishing different
template arguments.
This PR relands the refactoring part of the previous attempt, still
making it possible to have instantiated parameters before checking C++26
fold expression constraints, plus a regression test.

as an implicit argument
* `DynBlockMemSize` (this is the adjusted value in PluginInterface and
pass to the RTLs) as the `TotalBlockMemSize`.
Changing the first usage as this seems a leftover from #152831 where
usages in the plugins where changed to `DynBlockMemSize`.

RegisterPressure: Remove dead defs correctly (#222627)
When an instruction has overlapping register defs where only some carry
the dead flag (for example a dead super-register def alongside a live
sub-register def), the collector left the shared register units in both the live and
dead def sets. That produced a PressureDiff decrement with no matching increment
and tripped the "PSet overflow/underflow" assertion in getUpwardPressureDelta.
A register unit is dead if any def covering it is dead, regardless of
operand order. Reconcile by subtracting the dead defs from the live defs instead
of the reverse: removeRegLanes only clears the overlapping units, so a def
keeps any units a dead def does not cover.
Fixes #155807.
Fixes #149144.
Fixes #76416.
Fixes #205272.

[AMDGPU] Prevent folding of FMAC into FMAAK with two literals (#217438)
Currently the `foldImmediate` function can fold FMAC into FMAAK with two
literals causing a verifier failure:
```
*** Bad machine code: VOP2/VOP3 instruction uses more than one literal ***
- function: fold_fmac_to_fmaak
- basic block: %bb.0 (0x627ad4dd40d0)
- instruction: %3:vgpr_16_lo128 = contract nofpexcept V_FMAAK_F16_t16 10526, killed %4:vgpr_16_lo128, 8478, implicit $mode, implicit $exec
```
This change checks if a newly formed FMAAK is valid, and in a case two
literals are used it introduces a MOV to legalize the instruction.

[SimplifyCFG] Fix use-after-free in switch-on-select remap when the compared value is a PHI (#223632)
Fixes #223138
`simplifySwitchOnSelectRemap` turns `switch (select (X == C), K, X)`
into `switch X` and retargets case `C` to wherever `K` goes. It dropped
the old edge for `C` with `removePredecessor` before it installed `X` as
the switch condition. When `X` is a PHI in that old destination, which
is what happens when case `C` branches back to the switch's own block,
dropping the edge leaves the PHI with a single input, so it gets folded
and erased. The switch was then made to use the erased PHI. Everything
after that was reading freed memory, which is why the reported assertion
moves around between SimplifyCFG's dominator tree update,
ScalarEvolution's `isSCEVable` check and instcombine depending on the
run.
The fix is to set the switch condition to `X` before touching the CFG.
If the PHI fold happens, its RAUW now rewrites the switch operand along
with the compare and select, and the stale pointer is never used again.

[Flang][OpenMP] Support declare target on interfaces local to procedures (#218877)
Declarative directives implicitly affecting the surrounding procedures
are handled differently for interface procedures in Flang due to the
fact that the corresponding evaluation during lowering is attached to
the parent program unit, rather than the interface.
However, the current implementation to handle this edge case for
`declare_target` is based on the incorrect assumption that this can be
detected by comparing the owning procedure's symbol to the symbol of the
program unit lexically containing the directive. This fails whenever an
interface is located anywhere except for the main program.
Instead, this patch queries the details of the program unit containing
the directive to check directly whether it's an interface. Anything
else, including alternative entries to a procedure, is handled in the
regular way.

[X86] Lower bf16 round-to-integer on AVX10.2 via vrndscalebf16 (#213276)
Follow-up to #212245.
floor/ceil/trunc/rint/nearbyint/roundeven on bf16 are currently treated
as illegal causing them to be
promoted and causing scalarization of the vector cases.
AVX10.2 has packed vrndscalebf16, so mark these operations Legal for
v8bf16/v16bf16/v32bf16. The existing patterns already turns them into
X86ISD::VRNDSCALE with the matching immediate, so no new patterns are
needed.
Scalar bf16 reuses the path previously added in #212245.
llvm.round is left out since it is round-half-away-from-zero, which
vrndscale cannot encode.
For the strict version I kept the the old legalization for now since the
avx10.2 Instructions have hardcoded rounding and exception behavior.
(Further todo from my testing some of the strict versions need also some
extra handling since they currently will fail to select and crash the
compiler)
Used AI to code review and reword text.

[Flang] Avoid crash resolving restricted specific intrinsics (#217852)
Name resolution assumed that every specific intrinsic function handled
in a procedure context was unrestricted and had a numeric result. An
undeclared LLT used as a procedure pointer target therefore triggered a
CHECK because LLT is restricted and returns LOGICAL.
Rename the handler to reflect that it resolves both restricted and
unrestricted specific intrinsic functions. Preserve result types only
for unrestricted intrinsics; restricted intrinsics retain an untyped
symbol so later semantic checks can issue the appropriate diagnostic.

LowerAtomic in cmpxchg lowering creates a select to figure out what to

probability of. So mark the branch weights explicitly unknown.
It seems like we were lacking coverage of this case before #223157,
which made this test pop up on the profcheck bot.

Unify no-wrap queries in new isKnownNoWrap helper, which checks both
wrap flags on instructions and query-based reasoning in a single place.
Checks signed/unsigned wrap depending on a flag.
Update both decompose and tryToStrengthenFlags to use shared helper.
This improves results in a number of cases, because some rules were only
implemented for tryToStrengthenFlags and others in decompose:
https://github.com/dtcxzyw/llvm-opt-benchmark-nightly/pull/1313
Note that there are 2-3 small regressions due added flags/removed
branches pessimizing other parts of the pipeline.
Compile-time impact in the noise for geomean. Notable individual changes
is mafft -0.05% in stage1-ReleaseThinLTO, and lencod +0.05% for
stage2-O3.

[lldb][Windows] Key lldb-server's loaded-module list by base address (#223445)
`NativeProcessWindows` keys `m_loaded_modules` by `FileSpec`, so a
second mapping of an already-loaded DLL overwrites the first one's base
address, and `OnUnloadDll` then erases by address. The wrong mapping
gets dropped.
This reproduces reliably in swiftlang where `swiftCore.dll` is loaded
twice.
This patch maps by base address instead (the identity `UNLOAD_DLL`
carries), so an unload resolves to the right file and only retires the
reported entry when it is that file's last mapping.
It introduces the `LoadedModuleList` class to key the modules correctly
and 9 regression unit tests.

[mlir][sparse] Lower affine before SCF to CF in sparsifier (#219860)
Fix the lowering order in the sparsifier pipeline by running
`convert-scf-to-cf` after `lower-affine`.
Previously, `convert-scf-to-cf` ran while Affine control-flow operations
could still be present. For example, lowering an `scf.if` nested inside
an `affine.for` introduces multiple blocks into the loop body, violating
`affine.for`'s single-block region requirement and causing verification
to fail.
Running `lower-affine` first converts Affine control flow to SCF. The
subsequent `convert-scf-to-cf` pass can then lower both the existing SCF
operations and those introduced by Affine lowering to CFG-based control
flow.

[X86] Require legal result types for f32 estimates
The single-precision paths in `getRecipEstimate` and `getSqrtEstimate`
match a fixed set of scalar and vector f32 types, then check the
corresponding subtarget features. Those checks do not imply that the
result type is legal. Soft-float makes these result types illegal. Scalar
f32 is also illegal on a 32-bit SSE1 target without SSE2 or x87. The hooks
can then build an X86-specific estimate node with an illegal result type
before type legalization. Type legalization has no rule for that node, so
compilation fails.
Require a legal result type before entering the single-precision estimate
paths. The f16 paths in these hooks already require a legal type. After
this patch, the f32 paths match that behavior. The hooks return no estimate
for an illegal result type, so the original division or square root stays
in the DAG and follows its normal lowering. Estimate code generation for
legal result types is unchanged.

[Clang] Keep qualifiers outside of OverflowBehaviorType nodes (#222190)
`__typeof_unqual__` wasn't stripping `const` off of an overflow behavior
type:
```c
__typeof_unqual__(const __ob_trap int) x; // '__ob_trap const int'
```
The canonical type was always right, so `x` really is writable -- we
just printed it as const, which is the opposite of the truth.
`getOverflowBehaviorType()` hoisted qualifiers out for the canonical
type but stored the underlying type verbatim in the sugar node, so
`const __ob_trap int` became `OBT{const int}` with nothing qualified at
the `QualType` level. `getUnqualifiedType()` checks the canonical type
to decide there's something to strip, then strips it by desugaring one
step at a time. `OverflowBehaviorType` isn't sugar, so that walk
dead-ends on it and the qualifiers never come off.
So the rule is: a type node you can't desugar through shouldn't have a
canonical type with local qualifiers on it. Split the qualifiers off at
construction and put them back outside the node, which is where the
canonical already puts them.
Local qualifiers alone aren't enough here. `__ob_trap cint`, where
`cint` is a `typedef const int`, has the const in its canonical type but
not in its local qualifier set, and it's broken the same way.
`getSplitUnqualifiedType()` gets both. We lose the `cint` spelling in
that case but I think that's fine... that typedef is what was hiding the
qualifier in the first place.
While here, let `canPrefixQualifiers()` prefix an OBT so we print `const
__ob_trap int` instead of `__ob_trap int const`. That list is for types
that wrap the declarator, and an OBT just puts a keyword in front of an
integer like `_BitInt` and `_Atomic` do. We were already printing the
same type two different ways in attr-overflow-behavior.cpp, which is a
pretty good hint it was in the wrong list.
Note the new test checks the *printed* types. Since the canonical type
was never wrong, anything that only looks at canonical types passes
either way and doesn't actually test this.
Also spell out in the docs that an OBT is a type specifier and not a
qualifier.

CodeGen: Remove TargetOptions::EABIVersion (#222672)
The field's only effect was gating the __aeabi_mem*[4|8] libcalls via
the IsEABI4/IsEABI5 predicates. That distinction is derivable from the
triple's environment, so replace the two predicates with a single
triple-derived IsEABIVersion and delete the field.
The clang -meabi option and clang::TargetOptions::EABIVersion are
retained (now codegen-inert); the llc/opt -meabi flag is removed. -meabi
now only takes effect on triples with a bare-EABI/GNU environment pair
(arm-none-eabi <-> gnueabi), which is the only case with a triple
representation.

RuntimeLibcallsEmitter: Let a consumer's own library variant beat its exclusion (#221953)
A target can pull a shared library via LibraryRef<Lib, [impls]> to drop
some impls, then re-add its own versions through a same-name library variant
guarded on that target. Previously the exclusion's setUnavailable calls were
emitted at the end of setAvailableLibFuncs_<name>, after every variant, so they
clobbered the target's own re-adds.
Defer emitting a variant until after the exclusions when it re-adds an
impl its own consumer excludes (same predicates), so the target's re-add wins
while the exclusion still suppresses every other variant's contribution.
This is yet unused infrastructure for future changes.

[CMake] Prune dead and unnecessary try_compiles from config.h (#223765)
This relands the change directly on `main` after #223600 was
accidentally
merged into its stacked base branch. This reuses the approvals from
@aengelke and @MaskRay on #223600.
Several config-ix checks either have no consumer or can be performed
directly by the source that needs the feature. Remove six compiler
invocations from a typical Linux configure:
* HAVE_PTHREAD_MUTEX_LOCK has been unused since LLVM switched its mutex
implementation to std::recursive_mutex in 2019.
* The Linux magic-header results have never been propagated to config.h,
so CMake builds already use Path.inc's fallback constants.
* FE_ALL_EXCEPT and FE_INEXACT can be tested directly after including
cfenv.
* The Valgrind and CrashReporter headers can be detected with
__has_include in their only consuming translation units.
Also remove the obsolete definitions from the GN and Bazel
configurations.
In a fresh minimal LLVM configure, CMake profiling attributed 2067.1 ms
to 45 config-ix probes before this change and 1846.9 ms to 39 probes
after it.

[UTC] Strip only standalone positional %s in update_test_checks.py (#221153)
Previously, update_test_checks.py used tool_cmd_args.replace("%s", "")
to strip the input file when passing the IR via stdin. However, this
blindly removed "%s" from any option argument, leaving an empty value
(e.g., -lowertypetests-read-summary=).
Update the argument stripping to only remove standalone positional
"< %s" or "%s", preserving option arguments with "%s" values so they can
be expanded via common substitutions.
This enables update_test_checks.py to work for tests such as
llvm/test/Transforms/LowerTypeTests/cfi-jumptable-hotness-summary.ll,
which passes -lowertypetests-read-summary=%s on the RUN line.

[[mlir][linalg] Infer reduction-neutral padding values in rewriteAsPaddedOp (#216517)
**Problem**:
with no explicit options.paddingValues, rewriteAsPaddedOp padded every
operand with zero — silently corrupting reductions (a padded
maximumf/mulf element gets combined).
**Change**:
Added a new public linalg::inferPaddingValues(builder, toPad) to pick a
semantics-preserving value per operand:
- no reduction dim → zero;
- contraction → zero (0 annihilates through the multiply);
- other reductions → the combiner's neutral (-inf for maximumf, 1 for
mulf, …), found via matchReduction so the real accumulator combiner is
used.
rewriteAsPaddedOp calls it when options.paddingValues is empty. If no
value can be inferred, it returns failure() with the error "could not
infer a padding value"; the caller is then expected to determine the
value and supply it explicitly through options.paddingValues.

get the concept of required passes that perform optimizations and want
to skip them when running under opt bisect. This occurs for passes like
SelectionDAG and StackColoring. Add a helper function to make it easy to
query, although make it specific to opt bisect unlike the LegacyPM
skipFunction. A helper function is slightly more convenient (i.e., no
need to forward the pass name explicitly).

[IR] Generalize !amdgpu.ignore.denormal.mode into !atomic.ignore.denormal.mode (#217585)
The !amdgpu.ignore.denormal.mode metadata tells the backend that an
atomicrmw fadd need not honor the function's denormal mode, so a native
atomic instruction whose denormal behavior is fixed in hardware may be
used instead of a CAS loop. Nothing about that is AMDGPU specific: NVPTX
has exactly the same problem with atom.add, whose FTZ behavior depends
on
the address space and cannot be controlled.
Promote it to a target independent fixed metadata kind,
!atomic.ignore.denormal.mode, and switch the AMDGPU, SPIR-V and OpenMP
producers and consumers over to it. Document it in LangRef, and point
AMDGPUUsage at that description rather than duplicating it.
Existing IR keeps working: AutoUpgrade renames the metadata on atomicrmw
instructions when parsing textual IR and when materializing bitcode. The
upgrade is deliberately scoped to atomicrmw rather than being applied to
every attachment of that name, since that is the only place the metadata
was ever meaningful. Because bitcode can be materialized one function at
a time, the bitcode side hooks into BitcodeReader::materialize() rather
than a module-wide pass, which is the path clang's bitcode linking
takes.
This is not intended to change behavior for any existing target.

variable while the lower bound and step are i32 literals, so both are
converted to i64 before being passed through host_eval.

This DOES move checking functions out of CodeGen and into CodeGenUtils
so both can use it.
This is a diagnostic for builtins/etc that is built in to classic
codegen. We have to implement it, because otherwise autoconfig thinks
that we support AVX without a flag, and thus causes us to fail builds
later on that now expect __AVX__/etc to be defined without enabling
them.

rejected as potential homogeneous aggregates.
This change adds handling for `ConstantMatrixType` and classifies such
matrix types depending on whether they otherwise meet the criteria.

-----------
[Clang] Reject overflow behavior types on _Atomic (#222179)
atomic read-modify-write operations aren't instrumented for overflow. `counter++` on an `_Atomic` object lowers to a single `atomicrmw`, and this is true for plain atomic types under `-fsanitize=signed-integer-overflow` too.
That's a problem for `__ob_trap`, which is supposed to be checked no matter what the global flags say:
```c
typedef int __ob_trap trapping_int;
_Atomic trapping_int counter;
int x = counter + 1; // checked
counter++; // not checked
```
A guarantee that only holds for some expressions is worse than none, so reject the combination outriht. Let's also reject `__ob_wrap` too so the rule doesn't depend on the behavior kind... wrap has minimal use here anyways.
Applying an OBT specifier over an atomic type was already an error, though it unhelpfully reported `_Atomic(int)` as a non-integer type even though it is. Applying `_Atomic` over an existing OBT was accepted, which is where the unchecked read-modify-write came from... this was a bug that is now fixed because we are no longer trying to apply OBT on top of `_Atomic`. This is all made more clear by better diagnostics too :)
We can relax this later if someone needs it. I think instrumenting checked atomic rmws would mean lowering to a cmpxchg/CAS loop.

[LLVMABI] Add CanBeFlattened to abi::ArgInfo (#220558)
Mirror `clang::CodeGen::ABIArgInfo::CanBeFlattened` on `abi::ArgInfo` so
a classifier can keep a Direct record coercion in one piece, as
AAPCS-VFP homogeneous aggregates, AMDGPU direct aggregates and x86
vectorcall HVAs require. The bit defaults to true, so existing
classifiers are unchanged. It is exposed through `getCanBeFlattened()`
and a chainable `setCanBeFlattened()`, both Direct-only like the classic
accessor.
The MLIR `ArgClassification::canFlatten` and the CIR rewriter already
honour the flag; the CIR bridge will read the new bit with the first
classifier that clears it.

When the runInTerminal launcher fails, the debug adapter cannot

This patch makes the serialized field name match the parser and adds a
round-trip test covering launcher error propagation.

[clang][python] Make .git_archival.txt deterministic. (#223362)
Without an explicit `abbrev` option, `$Format:%(describe:...)` uses
Git's dynamic object abbreviation length (`find_unique_abbrev`). In a
large, rapidly growing repository like `llvm-project`, new commits can
potentially collide with existing short-SHA prefixes, causing GitHub's
`git archive` servers to emit longer short-SHAs over time for historical
commits. This mutates `clang/bindings/python/.git_archival.txt` inside
GitHub's dynamically generated `.tar.gz`/`.zip` source archives,
breaking downstream builds (such as OpenXLA/Bazel) that verify archive
SHA-256 checksums.
Specify `abbrev=40` so `describe-name` always uses the full 40-character
commit hash. `hatch-vcs` slices the parsed node ID to 10 characters when
formatting versions, so the resulting Python package version is
unchanged.

`parseMacroCall()` used `nextToken()` to consume the end of a configured
macro call, which also processed the following token. For adjacent macro
calls, this could expand the second call first and leave macro
reconstruction state out of order, causing a crash when the second
expansion starts with a comment.
This commit changes `parseMacroCall()` to consume the last token without
processing the following token, preserving source-order expansion. It
also prevents trailing comments from becoming part of the reconstructed
macro call.

[MLIR][XeVM] Hoist contiguous-slice shuffles through n-ary elementwise ops (#222452)
XeGPU expresses vector operands in their logical element type, so
per-lane compute chains can end up wider than the SPIR-V backend can
legalize as a single operand. HandleVectorExtractPattern already narrows
such chains by hoisting a contiguous-slice shufflevector upward through
unary element-wise ops (fpext/fptrunc/bitcast), merging shuffle chains,
and folding into smaller loads. But it stops at n-ary ops, so a chain
like
%0 = llvm.fdiv %a, %b : vector<32xf32> // wide, binary
%1 = llvm.shufflevector %0, %0 [0..15] : vector<32xf32> // legal 16-wide
slice
keeps a wide vector<32xf32> compute that the backend rejects.
This extends the pattern to hoist a contiguous slice through n-ary
element-wise ops as well: slice each same-length vector operand with the
same mask and re-create the op at the narrow width. The freshly created
operand slices keep hoisting upward (merging, or folding into loads)
until they reach operands that are already legal width, so the whole
compute chain collapses to the slice width - with no target-specific
width limit, since the width is inherited from the slice.
Length-changing and packed-payload ops (e.g. bitcast, truncf) are left
untouched.

[bazel] Add script for finding files not in the graph (#220343)
This is useful to make sure that globs cover all files in a given
subdirectory. Right now this doesn't cover many directories because we
don't have tons of tests in bazel but if we eventually add those we can
more easily spot ones we miss with this script.

[SPIRV] Emit RuntimeDescriptorArrayEXT capability for all unbounded array types (#222819)
Previously, the `RuntimeDescriptorArrayEXT` capability was emitted only
for image descriptor arrays. This change emits the capability for the
shader whenever resource array has `ArraySize == 0`.
This covers all supported runtime descriptor array types, including
images, structured buffers, samplers, and counter descriptor arrays.
Emitting the capability for these arrays is necessary to support dynamic
resources in SPIR-V.

[CodeGen] Fix -fsanitize=array-bounds for __sized_by / _or_null pointers (#213795)
`EmitCountedByBoundsChecking()` assumed a CountAttributedType is always
a __counted_by pointer. That isn't true; there are four versions of the
attribute:
* `__counted_by`: Already handled correctly.
* `__counted_by_or_null`: Incorrectly handled.
* `__sized_by`: Incorrectly handled.
* `__sized_by_or_null`: Incorrectly handled.
In particular:
* __sized_by / __sized_by_or_null: the loaded bound is a byte count, but
the
element index was compared against it directly, so an access was only
flagged once the index exceeded the byte count -- missing out-of-bounds
accesses for a pointee larger than one byte. Convert the loaded byte
count
into an element count by dividing it by the element size (`bound /
sizeof(element)`) so the check can compare the (element) index directly.
`counted_by` already counts elements and is unchanged; a void (or
otherwise
zero-/unknown-sized) pointee uses the GNU convention of element size 1,
i.e.
no conversion. Signed division is used for a signed count field so a
negative
byte count stays non-positive and is still rejected by the
negative-bounds
guard in EmitBoundsCheckImpl (unsigned division would turn it into a
large
positive count).
* __counted_by_or_null / __sized_by_or_null: a null pointer describes no
accessible memory, but the null case was ignored, so an access through a
null pointer with a non-zero count was not trapped. Treat the bound as 0
when the pointer is null.
Both adjustments are applied to the loaded bound in
EmitCountedByBoundsChecking before it is handed to EmitBoundsCheckImpl;
the bounds-checking machinery and the runtime handler are left unchanged
and continue to work in terms of the element index. Plain `__counted_by`
and the general array-bounds path are unaffected.
I did try an alternative implementation where the comparison was done in
terms of bytes (rather than elements which this patch does), but this
had several disadvantages:
* It was less correct. Because the element-count implementation uses
truncating division, a `__sized_by()` whose size is not a multiple of
the
pointee size rounds the bound down, so an access to a partially
in-bounds
object is caught. A byte-level check would instead only verify that the
first byte of the object is in bounds, which would allow accessing a
partially in-bounds object.
* When benchmarking (small microbenchmarks targetting arm64e), it
appeared that the division implementation was faster. Note that an
unsigned count field and an element size that is a power 2 produces
the best LLVM IR because unsigned division by a power of 2 can be
turned by the optimizer into a `lshr` instruction.
* It required changes in `CodeGenFunction::EmitBoundsCheckImpl` as well,
which made the change more invasive.
Note while working on this I did discover an existing bug where if the
base (e.g. `side_effect()->ptr[0]`) has a side-effect it is incorrectly
evaluated multiple times. Fixing that is out-of-scope for this patch and
will be handled later.

[SLP]Fix splat gather subtree keep/drop to restore lost vectorization
The splat gather subtrees were kept on cost ties and resurrected by the
trimming revert without a profitability re-check, and dropping them left
the gathered loads built for them orphaned and forcing extracts. This
rejected otherwise profitable VF=2 trees. Keep subtrees only when
strictly profitable, re-evaluate them against the restored tree on a
revert, and delete the gathered loads left dead by a drop.
Fixes the remaining regressions from #220250 reported in #221717.

exceptions to an operation that will later be lowered to target-specific
IR to call std::unexpected, while exceptions that match the dynamic
exception specification are routed to normal unwind handling.
Target-specific EH ABI lowering will be added in a follow-up change.

[Flang][OpenMP] Remove close map type member removal code from MapInfoFinalization (#219438)
This should no longer be required as we removed the application of close
automatically in USM mode in a prior PR. So they bug this was originally
put in place for is now addressed without the need for this PR. And
whilst it was fine to put in place for a bug the user had no control of
(automatic application of close to descriptor members), it's not our
place to intervene in scenarios where a user is making explicit errors
in their mapping, e.g.
map(to: dtype) map(close, to: dtype%x, dtype%y)
A user should be left to shoot themselves in the foot if that's there
goal (or perhaps there's some really wild or single memory system
architectures that would allow this), we'd ideally prevent this as a
compiler warning or error as opposed to fixing the problem
under-the-hood for them. Otherwise we help create unportable code for
the user, alongside forcing ourselves to maintain the underlying fix.
