[CIR] Implement EH lowering to Itanium form and LLVM IR (#184386)
This introduces a new pass to lower from a flattened, target-independent
form of CIR to a form that uses Itanium-specific representation for
exception handling. It also includes a small amount of code needed to
lower the Itanium form to LLVM IR.
Substantial amounts of this PR were created using agentic AI tools, but
I have carefully reviewed the code, comments, and tests and made changes
as needed.

[lldb] Fix 10 year old leak of `g_debugger_list_ptr` (#184259)
Roughly 10 years ago, in aacb80853a46bd544fa76a945667302be1de706c, Greg
deleted the call to delete g_debugger_list_ptr because of a race
condition:
> Fixed a threading race condition where we could crash after calling
Debugger::Terminate().
>
> The issue was we have two global variables: one that contains a
DebuggerList pointer and one that contains a std::mutex > pointer. These
get initialized in Debugger::Initialize(), and everywhere that uses
these does:
>
> if (g_debugger_list_ptr && g_debugger_list_mutex_ptr)
> {
> std::lock_guard<std::recursive_mutex>
guard(*g_debugger_list_mutex_ptr);
> // do work while mutex is locked
> }
>
> Debugger::Terminate() was deleting and nulling out g_debugger_list_ptr
which meant we had a race condition where someone might do the if
statement and it evaluates to true, then another thread calls
Debugger::Terminate() and deletes and nulls out g_debugger_list_ptr
while holding the mutex, and another thread then locks the mutex and
tries to use g_debugger_list_ptr. The fix is to just not delete and null
out the g_debugger_list_ptr variable.
However, this isn't necessary as long as we persist ("leak") the mutex
and always check it first. That's exactly what this patch does. Without
it, the assert in Debugger::Initialize is incorrect.
```
assert(g_debugger_list_ptr == nullptr &&
"Debugger::Initialize called more than once!");
```

[CIR] Split cir.binop into separate per-operation binary ops (#184227)
Replace the single `cir.binop` operation (dispatched via a `BinOpKind`
enum) with nine distinct ops — `cir.add`, `cir.sub`, `cir.mul`,
`cir.div`, `cir.rem`, `cir.and`, `cir.or`, `cir.xor`, and `cir.max` —
each with precise type constraints and only the attributes it needs
(nsw/nuw/sat on add/sub via `BinaryOverflowOp`).
A new `BinaryOpInterface` provides uniform `getLhs`/`getRhs`/`getResult`
access for passes and analyses.
The monolithic switch-based CIRToLLVMBinOpLowering is replaced by per-op
patterns generated through the existing CIRLowering.inc TableGen
infrastructure, with shared dispatch factored into two helpers:
`lowerSaturatableArithOp` for add/sub and `lowerIntFPBinaryOp` for
div/rem.

[lldb] Fix the GoogleTest teardown in the DAP unit tests (#184262)
Some of the DAP tests define a static method named `TeatUpTestSuite`
which is calling `SBDebugger::Terminate`. Besides the typo, the correct
method is `TearDownTestSuite`, which GoogleTest calls after running the
last test in the test suite.
When addressing this, I realized that currently you can't really call
Initialize and Terminate multiple times in the same process. This
depends on:

I have an unwind failure where the eh_frame for a

register 33, which lldb treats as cpsr.
https://github.com/ARM-software/abi-aa/blob/main/aadwarf64/aadwarf64.rst#dwarf-register-names
Register 33 is ELR_mode, which isn't defined as a register in any of the
AArch64 register definition files in lldb today, so I'm not adding it to
the header files.

[lldb] Remove Debugger::{FindTargetWithProcessID, FindTargetWithProcess} (#184446)
In #184259, Jim noticed that Debugger::FindTargetWithProcess and
Debugger::FindTargetWithProcessID are rather poorly designed APIs as
tehy allow code running in one Debugger to mess with Targets from
another Debugger. The only use is Process::SetProcessExitStatus which
isn't actually used.

[Clang] Permit floating point and pointer values in most atomic ops (#183843)
Summary:
We already support floating point arguments for the standard atomic
functions. LLVM supports these in most cases as well. This PR unifies
the handling and allows this in the cases that the LLVM IR supports.

[X86] support reserve r8~r15 on X86_64 (#180242)
Which is under discussion in
https://github.com/llvm/llvm-project/issues/179036
Add new options -ffixed_r{8-15} for clang X86 target, like option
"-ffixed_x" for RISCV/AArch64 target.
Also, add target-feature +reserve-r{8-15} for the X86 backend.
The registers which are specified reserved will not be used in
RegAlloc/CalleeSave. Then the reserved registers can be maintained by
user. It will be useful for the runtime/interpreter implementation.
Other registers are used in specific instructions or mechanism, so they
can't be reserved.

[WebAssembly] Use MVT::i32 instead of i1 in performAnyAllCombine (#183866)
The CombineSetCC helpers and performAnyAllCombine generate MVT::i1
results.
However MVT::i1 is an illegal type in WebAssembly, and this combiner can
run either before or after legalization. Directly creating the intrinsic
and negating its result using XOR instead of i1 and a NOT operation
avoids this problem.

Some original work was done around this in
df1d786c460e0e47c9074f3533f098190ebfbc1b, which was then done in
upstream Google benchmark in
https://github.com/google/benchmark/commit/d8db2f90b643eb28a12976beb4d57bcfb639911d.
The original work done in the patch implementing this feature doesn't
seem to account for as many cases as the upstream patch does. This patch
reverts the diff in df1d786c460e0e47c9074f3533f098190ebfbc1b and applies
the applicable hunks from the upstream patch.

[RISCV][GISel] Replace buildInstr with BuildMI (#183714)
As @arsenm mentioned in some of my PRs, such as:
https://github.com/llvm/llvm-project/pull/171092, we should use
`BuildMI` instead of `MachineInstrBuilder::buildInstr` in Selector.
This PR is tring to replace all `MachineInstrBuilder::buildInstr` with
`BuildMI`.

[GVN] Fix crash when svcount is used with globals-aa (#184347)
When -globals-aa is used, `analyzeLoadAvailiability` calls
`analyzeLoadClobberringStore` which in turn calls
`isFirstClassAggregateOrScalableType` which is using
`isa<ScalableVectorType>`. Ideally it should use type's isScalableType()
method.
The crash does not occur when default (BasicAA) is used because
`analyzeLoadAvailiability` function does not take the load clobbering
path as BasicAA returns `Def`.

[RISCV] Sink instructions so AVL dominates in RISCVVLOptimizer (#184155)
The last feature that RISCVVectorPeephole::tryToReduceVL has that
RISCVVLOptimizer doesn't is that if the vl to reduce to doesn't dominate
a vector pseudo, it can sink the pseudo below the vl definition if it's
safe to do so.
This PR shares the logic to check for physical register clobbering in
RISCVInstrInfo, but there may be a better place for it.
The DemandedVLs DenseMap needs to be switched to a MapVector to get
deterministic ordering, since the order in which we sink instructions
can affect the resulting codegen.
This helps removes a few vsetvli toggles in llvm-test-suite.

[MC][test] Add relax-branch-align.s demonstrating unnecessary branch relaxation (#184551)
The two-pass relaxation approach (relaxFragment, then layoutSection)
can unnecessarily relax a backward branch from short (2B) to near (5B).
When a forward branch relaxes (2B->6B), it shifts the backward target
by +4B. A .p2align between target and source absorbs this growth. The
true displacement is -125 (fits short), but the two-pass approach
evaluates the backward branch with stale target offsets, seeing -129
(beyond [-128,127]) and relaxing it unnecessarily.

[ELF] Add target-specific relocation scanning for LoongArch (#182236)
Implement LoongArch::scanSectionImpl, following the pattern established
for x86, PPC64, SystemZ, AArch64. This merges the getRelExpr and TLS
handling for SHF_ALLOC sections into the target-specific scanner,
enabling devirtualization and eliminating abstraction overhead.
- Inline relocation classification into scanSectionImpl with a switch
on relocation type, replacing the generic rs.scan() path.
- Use processR_PC/processR_PLT_PC for common PC-relative and PLT
relocations.
- Inline TLS handling: IE->LE optimization for _PC_ variants only (not
_PCADD_ or absolute), TLSDESC->IE/LE for non-extreme code model,
GD/LD flag setting without going through generic handleTlsRelocation.
- Remove adjustTlsExpr by inlining its logic into scanSectionImpl.
- Remove LoongArch-specific code from Relocations.cpp:
handleTlsRelocation, execOptimizeInLoongArch, and the sort condition.
- Simplify getRelExpr to only handle relocations needed by
relocateNonAlloc, scanEhSection, and the extreme code model fallback
in relocateAlloc.

[MC] Fuse relaxation and layout into a single forward pass (#184544)
Replace the two-pass inner loop in relaxOnce (relaxFragment +
layoutSection) with a single forward pass that sets each fragment's
offset before processing it.
- Extract relaxAlign from layoutSection's FT_Align handling and call
it from relaxFragment. FT_Align padding is computed inline with the
tracked Offset, so alignment fragments always see fresh upstream
offsets. This structurally eliminates the O(N) convergence pitfall
where stale offsets caused each iteration to fix only one more
alignment fragment.
- The new MCAssembler::Stretch field tracks the cumulative upstream size
delta. In evaluateFixup, for PCRel fixups during relaxation, Stretch
is added to forward-reference target values (LayoutOrder comparison).
This makes displacement = target_old - source_old, identical to the
old two-pass approach, preventing premature relaxation for
span-dependent instructions.
- FT_Fill/FT_Org removed from relaxFragment; `if (F.Offset != Offset) in
the fused loop detects their size changes.
- layoutSection is retained for initial layout and post-finishLayout.
This fixes the FT_BoundaryAlign linear time convergence issue reported
by #176535. In addition, backward branches near the short/near boundary
may benefit from tighter encoding when a .p2align between the target and
the branch absorbs upstream growth (see relax-branch-align.s).

[AMDGPU] Add half vector support for table-driven libcall optimization (#178638)
When replacing certain AMDGPU library calls with constant data vectors,
the existing implementation only handled single and double-precision
floats. This change extends the functionality to also support
half-precision floats.
Additionally, it refactors the function responsible for generating
constant float data vectors to improve readability and reduces code
duplication. In tandem with this refactoring, the patch relaxes the
check for constant data vectors to include any constant of vector type.
This allows other constant vectors to be processed, such as those
created from constant aggregate zeros (e.g. `<2 x float>
zeroinitializer`).

[DA] Remove consistent flag from Dependence class (#181608)
The `Dependence` class has a flag `Consistent`, but it's not clear what
it represents. This flag doesn't seem to be updated correctly during
analysis. There are no users of it, so I think this flag would be
unnecessary.
In addition, because of this flag, even minor code changes can alter
test results unintentionally (specifically, the presence/absence of a
string "consistent" in the test output). Such test changes can be
confusing and gradually add to the maintenance burden.
Given these points, it's better to remove the `Consistent` flag from the
`Dependence` class entirely.

[mlir] Add option to ignore commutativity in OperationEquality (#181507)
This adds a new flag, `IgnoreCommutativity`, to the OperationEquivalence
flags. When toggled, regular equivalence and hashing will be used
instead of calls to `checkCommutativeEquivalent` and
commutative-invariant hashing.
This means that commutative operations will not be considered equivalent
when their operands are in a different order (i.e. `arith.addi(%a, %b)`
vs. `arith.addi(%b, %a)`).

[SelectionDAG] Add expansion for llvm.convert.from.arbitrary.fp (#179318)
The expansion converts arbitrary-precision FP represented as integer
following these algorithm:
1. Extract sign, exponent, and mantissa bit fields via masks and shifts.
2. Classify the input (zero, denormal, normal, Inf, NaN) using the
exponent and mantissa fields.
3. Normal path: adjusting the exponent bias and left-shifting the
mantissa to fit the wider destination format.
4. Denormal path: normalizing by finding the MSB position of the
mantissa (via count-leading-zeros), computing the correct exponent from
that position, stripping the implicit leading 1, and shifting the
fraction into the destination mantissa field.
5. Assemble the destination IEEE bit pattern (sign | exponent |
mantissa) and select among the normal, denormal, and special-value
results.
Currently only conversions from OCP floats are covered, in LLVM terms
these are: Float8E5M2, Float8E4M3FN, Float6E3M2FN, Float6E2M3FN,
Float4E2M1FN.

[libc] Fix integration test args/env in LibcTest lit format (#184438)
Integration tests with ARGS or ENV in their add_integration_test() call
were being run with no arguments or environment variables by the
LibcTest lit format, causing failures in startup_args_test,
sprintf_size_test, getenv_test, execv_test, execve_test, and
getcwd_test.
Fix this by having add_integration_test() emit a sidecar
<executable>.params JSON file (via file(GENERATE)) whenever ARGS or ENV
are specified. LibcTest.execute() reads this file at test time and
passes the args and environment to the test executable.
Also always set PWD=exec_dir in the test environment so that
getenv("PWD") matches getcwd() for tests that compare them.

This breaks a tie where the `SEXT_IN_REG` in an expression like
`SUB(0, SEXT_IN_REG(VECTOR_EXTRACT(..))` can fold into the `SUB` or the
`VECTOR_EXTRACT`. Currently, the `SUB` is always preferred, but it's
better to fold the `SEXT_IN_REG` into the `VECTOR_EXTRACT` extract,
which allows for `SMOV` to be used.

[lldb] Change more uses of AppendMessageWithFormat to AppendMessageWithFormatv (#184337)
When the message includes a final newline, Formatv can add that for you.
The only unusual change is one place in platform where we need to print
octal. LLVM doesn't have a built in way to do this (see
llvm/include/llvm/Support/FormatProviders.h) and this is probably the
only place in the codebase that wants to. So I decided not to add it
there.
Instead I've put the number info a format adapter with the normal printf
specifier, then put that into the Formatv format.

[clang] Predefine `_MSVC_TRADITIONAL` in MSVC compatibility mode (#184278)
As of version 19.15 (Visual Studio 2017 version 15.8), MSVC predefines
the `_MSVC_TRADITIONAL` macro to indicate whether it is using the old
"traditional" preprocessor or the new standards-conforming preprocessor.
Clang now predefines `_MSVC_TRADITIONAL` as 1 when emulating MSVC 19.15
or later, since Clang supports most traditional preprocessor behaviors
(e.g. `/##/` turning into `//`) when running in MSVC compatibility mode.
Currently there isn't a situation where it makes sense for Clang to
report `_MSVC_TRADITIONAL` as 0, since MSVC compatibility mode only
attempts to be compatible with the traditional MSVC preprocessor.
However, this does mean that clang-cl cannot match MSVC's behavior of
implicitly enabling the conforming C preprocessor when compiling with
`/std:c11`, `/std:c17`, or `/std:clatest`.

[mlir][SCFToEmitC] Fix crash when scf.while carries a memref loop variable (#183944)
When a scf.while op has a loop-carried value whose type converts to
emitc::ArrayType (e.g. memref<1xf64>), the WhileLowering pattern
unconditionally called emitc::LValueType::get(arrayType), which
triggered an assertion because LValueType cannot wrap an array type.
Fix by returning a match failure in createVariablesForResults and
createVariablesForLoopCarriedValues when the converted type is an
emitc::ArrayType. This converts the crash into a proper legalization
failure.

[mlir][nvgpu] Fix crash in optimize-shared-memory pass with vector element types (#179111)
The `--nvgpu-optimize-shared-memory` pass crashed when processing
memrefs with vector element types (e.g., `memref<16x1xvector<16xf16>,
3>`). This occurred because getElementTypeBitWidth() calls
getIntOrFloatBitWidth(), which asserts the element type must be an
integer or float.
Thus, this PR adds an early-exit guard to return failure() when the
memref's element type is not a scalar int or float.
I wasn't sure if we should support vector types (by multiplying element
bit width by vector length) or just reject them. For now, I've
implemented it to return failure on non-scalar types.

[MLIR][Arith][Vector] Reject i0 integer type in arith and vector ops (#183589)
Add ODS type constraints that exclude zero-bitwidth integers (i0) from
operations in the arith and vector dialects. i0 has no meaningful
arithmetic representation and operations on it can trigger undefined
behavior (e.g. bitwidth calculations assuming non-zero width).
Changes:
- Add `AnyNonZeroBitwidthSignlessInteger` (as a `ConfinedType` over
`AnySignlessInteger`) and `AnyNonZeroBitwidthSignlessIntegerOrIndex`
to CommonTypeConstraints.td.
- Introduce `Arith_SignlessIntegerOrIndexLike` in ArithOps.td that wraps
`AnyNonZeroBitwidthSignlessIntegerOrIndex` via
`TypeOrValueSemanticsContainer`, and update
`SignlessFixedWidthIntegerLike`
to use `AnyNonZeroBitwidthSignlessInteger`. Replace all uses of the
shared `SignlessIntegerOrIndexLike` in ArithOps.td with the new
dialect-local constraint.
- Update `IndexCastTypeConstraint` to use
`Arith_SignlessIntegerOrIndexLike`.
- Update `BitcastTypeConstraint` to exclude i0 by composing the already-
defined `SignlessFixedWidthIntegerLike` and `FloatLike` constraints,
keeping the definition compact (3 alternatives instead of 7).
- Add `AnyVectorOfNonI0Elem` and `AnyVectorOfNonZeroRankNonI0Elem` in
VectorOps.td and apply them to `vector.contract`, `vector.reduction`,
`vector.multi_reduction`, `vector.outerproduct`, `vector.bitcast`, and
`vector.scan`.
- Update arith/invalid.mlir with explicit i0 rejection tests covering
all
integer op families (binary ops, cast ops, extended-multiply ops, cmpi,
bitcast, index_cast, index_castui) for both scalar and vector<N> forms.
- Update vector/invalid.mlir with i0 rejection tests for all covered
ops.
- Remove the now-invalid i0 canonicalization tests from
arith/canonicalize.mlir.

[mlir][Func] Use getMutableSuccessorOperands() in FuncOp verifier (#184589)
When verifying return-like terminators, use
getMutableSuccessorOperands() instead of getNumOperands() so that only
the operands passed to the parent region are checked against the
function result types. This handles terminators that implement
RegionBranchTerminatorOpInterface and carry additional operands for
other successor regions (e.g. loop back-edges).
Add tests using test.loop_block_term, which has both an iter operand
(passed back to the region) and an exit operand (passed to the parent).

Reproducer:
```

logical :: l1, l2
do while (l1())
if (l2()) then
call bar()
endif

```
The cause is a pass ordering issue between the SCFToControlFlowPass and
CfgConversionPass
[here](https://github.com/llvm/llvm-project/blob/d0f50d55746aa27e6467cb2bce66596da9da065b/flang/lib/Optimizer/Passes/Pipelines.cpp#L239-L240).
I think they need to be run simultaneously somehow because the both SCF
and FIR structured operations may contain each other, and none will be
happy to get block CFG generated inside their region by the pass
lowering the other.
Reverting while this is sorted out.

[mlir][llvm] Fix SROA crash on empty LLVM struct types (#184596)
When SROA runs on an alloca of an empty struct type (llvm.struct<()>),
it crashes with:
Assertion `\!subelementIndexMap->empty()' failed.
The root cause is in LLVMStructType::getSubelementIndexMap(): for an
empty struct (no body fields), the loop doesn't execute and an empty
DenseMap is returned as a non-null optional. Later, getTypeAtIndex()
asserts the map is non-empty, triggering the crash.
Fix this by returning std::nullopt for empty structs, indicating they
cannot be destructured. This is consistent with how LLVMArrayType
handles the zero-element case.

[Flang][OpenMP] DEFAULT(NONE) error checking on implicit references (#182214)
A variable with an unspecified data-sharing attribute under a
DEFAULT(NONE) clause only emits an error if the variable is explicitly
referenced in the body of the construct with DEFAULT(NONE).
Ex:
```
!$omp parallel default(none)
!$omp task
a = 1
!$omp end task
!$omp end parallel
end
```
gfortran will error with `‘a’ not specified in enclosing ‘parallel’` on
the above. flang doesn't error.
Fix moves the error check to `CreateImplicitSymbols` and checks the
variable for a violation in any of its enclosing contexts.

The attributes `exclude_from_explicit_instantiation` and
`dllexport`/`dllimport` serve opposite purposes.
Therefore, if an entity has both attributes, drop one with a warning,
depending on the context of the declaration.
In a template context, the `exclude_from_explicit_instantiation`
attribute takes precedence over the `dllexport` or `dllimport`
attribute. Conversely, the `dllexport` and `dllimport` attributes are
prioritized, in a non-template context.

This patch fixes the bug by creating a temporary decl for that purpose.
Though the temporary object should go away once we have the evaluation

[TableGen] Complete the support for artificial registers (#183371)
Artificial registers were added in
eb0c510ecde667cd911682cc1e855f73f341d134
as a means of giving super-registers heavier weights than that
of their subregisters, even when they only contain a single
physical subregister.
Artifical registers thus do exist in code and participate in
register unit weight calculations, but are not supposed to be
available for register allocation.
This patch completes the support for artificial registers to:
- Ignore artificial registers when joining register unit uber
sets. Artificial registers may be members of classes that
together include registers and their sub-registers, making it
impossible to compute normalised weights for uber sets they
belong to.
We have a use case downstream relying on this being supported,
which allows to avoid introducing a large number of additional
register classes.
- Not generate purely artificial register class intersections.
It is critical not to have such classes, as the common LLVM
codegen infrastructure will try to use them to constrain
classes of virtual registers instead of producing COPYs
whenever both the source and target register classes contain
the same artificial registers.
- Not generate sub-classes where classes with the same
non-artificial members already exist. This is mostly for
convenience. For example, the HI16-capable subset of AMDGPU's
AV_32 is VGPR_32, except VGPR_32 also contains the artificial
staging registers. If the staging registers are not ignored,
we'll end up having an additional generated register class,
AV_32_with_hi16_in_VGPR_16, -- harmless, but also useless.
Eliminates a few inferred AMDGPU register classes:
- VS_32_with_hi16
- VS_32_Lo256_with_hi16
- VS_32_Lo128_with_hi16
- VRegOrLds_32_and_VS_32_Lo256
- VRegOrLds_32_and_VS_32_Lo128
- SRegOrLds_32_and_VRegOrLds_32
Causes no register class changes for other targets.

[SPIRV] Rename `selectSelectDefaultArgs` to `selectBoolToInt` (#184120)
The function is used to extend a `bool` (vector or scalar) into `1/-1`
for `true` and `0` for `false` (vector or scalar).
There is no obvious "default" argument for a select operation, so the
original name is confusing.
This patch:
* Renames this function to better signal its intention,
* makes the boolean argument explicit in the function (instead of
implicit through the first register operand of the instruction),
* rename `I` to `InsertAt`.

The optin.cplusplus.VirtualCall checker reports warnings for virtual

in a system header (included via -isystem). Users cannot fix such code
and must resort to NOLINT suppressions.
Add a system header check in checkPreCall before emitting the report,
consistent with how other checkers (e.g. MallocChecker) handle this.

This is a duplicate of https://github.com/llvm/llvm-project/pull/180700
except that I also added some tests, fine to go with either PR, but we
should add the tests.
peekNextPPToken lexed a token and mutated MIOpt, which could clear the
controlling-macro state for main files in C++20 modules mode.
Save/restore MIOpt in Lexer::peekNextPPToken.
Add regression coverage in
LexerTest.MainFileHeaderGuardedWithCPlusPlusModules that checks to make
sure the controlling macro is properly set in C++20 mode.
Add source level lit test in miopt-peek-restore-header-guard.cpp that
checks to make sure that the warnings that depend on the MIOpt state
machine are emitted in C++20 mode.

[VPlan] Preserve IsSingleScalar for hoisted predicated load. (#184453)
The predicated loads may be single scalar (e.g. for VF = 1). We should
preserve IsSingleScalar when hoisting them. As all loops access the same
address, IsSingleScalar must match across all loads in the group.
This fixes an assertion when interleaving-only with hoisted loads.

[mlir][affine] Fix crash in vectorizeAffineLoopNest test utility for reduction loops (#184617)
The test utility function `testVecAffineLoopNest` called
`isLoopParallel` with a `reductions` output parameter, which populates
reduction descriptors when the loop performs a reduction. However, these
descriptors were never added to `strategy.reductionLoops` before calling
`vectorizeAffineLoopNest`. When the vectorizer then processed a loop
with `iter_args`, it found no reduction descriptors in the strategy and
hit an assertion failure.
Fix by registering the reduction loop descriptors in the strategy before
vectorization, matching what the production vectorizer code already does
correctly.

In verifyOperationAttribute(), the single-symbol path for shape.lib used
SymbolTable::lookupSymbolIn() followed by an explicit null check. The
array path at line 196-197 used dyn_cast<FunctionLibraryOp>() directly
on the lookup result, which asserts when the symbol is not found (null
pointer).
Fix: use dyn_cast_or_null<> instead of dyn_cast<> so that a missing
symbol falls through to the existing "does not refer to
FunctionLibraryOp" error diagnostic instead of asserting.

[SPIRV] Fix global emission for modules with no functions (#183833)
Right now we have a problem where if you have a LLVM module with globals
but no functions, a completely empty SPIR-V module is emitted.
This is because global emission is dependent on tracking intrinsic
functions being emitted in functions.
As a simple fix, just insert a service function, which the backend is
already set up to not actually emit, if there are no real functions.
The current use case of the service function is for function pointers. I
don't think it's possible that we need to both generate a service
function for function pointers and for globals with no functions, so I
just added an error (not an assert) just in case if we do need it for
both cases.
Probably we should rework global handling in the future to work without
these workarounds, but this is a pretty fundamental issue so let's work
around it with this simple change for now.
This change exposed an existing bug:
We consider basic blocks with no successors as fall-through
Also, fix some existing tests. The symptom was:
We previously emitted an empty module, but not that we don't, we hit a
`spirv-val` error about invalid Function StorageClass for globals
because no `addrspace` was specified. Set the `addrspace` to `1`
(`CrossWorkgroup`) in those tests.

[mlir][Func] Fix FuncOp verifier ordering via hasRegionVerifier (#184612)
FuncOp::verify() iterated over all blocks and called
getMutableSuccessorOperands() on any RegionBranchTerminatorOpInterface
terminator to check return types. This ran during the entrance phase of
verification — before child ops had been verified — so a malformed
terminator whose getMutableSuccessorOperands() assumed invariants
established by its own verify() could crash instead of emitting a clean
diagnostic.
Fix by switching to hasRegionVerifier=1: rename verify() →
verifyRegions() so the return-type checks run in the exit phase, after
all nested ops have already been verified.
To demonstrate the bug and guard against regression, add
TestCrashingReturnOp to the test dialect. The op implements
RegionBranchTerminatorOpInterface and report_fatal_errors in
getMutableSuccessorOperands() when its 'valid' unit-attr is absent,
reproducing the class of crash described above. The accompanying lit
test confirms a clean diagnostic is emitted rather than a crash.

[DTU] fix dominator tree update eliding reachable nodes (#177683)
The initial CFG looks like this:
After inlining, it looks like this:
It should be sufficient to add and remove the edges shown in the test, i.e.:
- add: `bb3->bb1.i` and `bb3->bb2.i`
- remove: `bb3->bb4`, `bb3->bb5` and `bb5->bb8`
New nodes, like `bb5.body`, get discovered when adding bb3->bb2.i. See the "StepByStep" variant of the test). Without the fix in this patch, however, `bb5.body` gets elided when the deleted edges get taken into account, and `DT` is left invalid.

[X86] remove unnecessary movs when %rdx is an input to mulx (#184462)
Closes: https://github.com/llvm/llvm-project/issues/174912
When generating a `mulx` instruction for a widening multiplication, even
if one input is placed in %rdx, LLVM won't place it in the implicit
first slot, instead it'll generate two movs before calling mulx to swap
the registers, which are unnecessary. GCC already has this optimization
(as shown in the issue) so this puts the two compilers closer to each
other on that front.

[mlir][AMDGPU] Add folders for memref aliases to TDM base creation (#184567)
The TDM base creation (amdgpu.make_tdm_base and
amdgpu.make_gather_tdm_base) take references to a
`%memref[%i0, %i1,, ...]` for the starting point of the tiles in
global/shared memory that the TDM descriptor refers to. Memory alias ops
can be safely folded into these operations, since these two memref
operands are just pointers to a scalar starting pint and don't have
semantics that depend on the memref layout (except to the extent that it
defines a location in memory).
While I'm here, I've cleaned up a few things, like the incorrect file
header and fixed the tests to not use integer address spaces.

[flang][OpenMP] Avoid implicit default mapper on pointer captures (#184382)
This change fixes incorrect implicit declare mapper behavior in Flang
OpenMP lowering.
Issue:
Implicit default mappers were being attached/generated for pointer-based
implicit captures, and also on data-motion directives. That could
trigger recursive component mapping that overlaps/conflicts with
explicit user mappings, causing runtime mapping failures.
Fix:
- Skip implicit default mapper generation for implicit pointer captures
(keep support for allocatables).
- Do not auto-attach implicit mappers on target enter data, target exit
data, or target update.
- Apply the same pointer guard in the implicit target-capture lowering
path.

[Hexagon] Use __HVX_IEEE_FP__ to guard protos that need -mhvx-ieee-fp (#184422)
Hexagon clang recently started to define __HVX_IEEE_FP__ when the
-mhvx-ieee-fp option is specified. Guard the intrinsic macros for
instructions that should only be available with -mhvx-ieee-fp with
__HVX_IEEE_FP__.
Additionally, the following NFC changes are included:
- NFC: Remove guards around HVX v60 intrinsic macros
Hexagon v60 is the oldest Hexagon version that supports HVX so these
guards were redundant. Presence of HVX is guarded separately, once
per the whole file.
- Remove comments from closing guards (HVX protos)
These comments served very limited function as they only guard
one macro. Also, they were incorrect. Instead of fixing remove them.
This will also reduce by the factor of two the amount of changes
when guarding conditions change.

[mlir][vector] Replace OneDimMultiReductionToTwoDim with OneDimMultiReductionToReduction (#184241)
The `OneDimMultiReductionToTwoDim` pattern had some issues. For the
input program:
```mlir
func.func @rank1_multi_reduction(%arg0: vector<8xf32>, %acc: f32) -> f32 {
%0 = vector.multi_reduction <add>, %arg0, %acc [0] : vector<8xf32> to f32
return %0 : f32
}
```
* when lowering using the inner-parallel strategy, the compiler would
essentially produce scalar code:
```mlir
func.func @rank1_multi_reduction(%arg0: vector<8xf32>, %arg1: f32) -> f32 {
%0 = vector.shape_cast %arg0 : vector<8xf32> to vector<1x8xf32>
%1 = vector.broadcast %arg1 : f32 to vector<1xf32>
%2 = vector.transpose %0, [1, 0] : vector<1x8xf32> to vector<8x1xf32>
%3 = vector.extract %2[0] : vector<1xf32> from vector<8x1xf32>
%4 = arith.addf %3, %1 : vector<1xf32>
%5 = vector.extract %2[1] : vector<1xf32> from vector<8x1xf32>
%6 = arith.addf %5, %4 : vector<1xf32>
... (repeats for all 8 elements) ...
%17 = vector.extract %2[7] : vector<1xf32> from vector<8x1xf32>
%18 = arith.addf %17, %16 : vector<1xf32>
%19 = vector.extract %18[0] : f32 from vector<1xf32>
return %19 : f32
}
```
* when lowering using the inner-reduction strategy, the compiler would
first unnecessarily transform it into a 2-D multi_reduction operation
<1x8xf32> and then extract an <8xf32> vector and apply reduction. The
canonicalization and folding would lead to the following final result:
```mlir
func.func @rank1_multi_reduction(%arg0: vector<8xf32>, %arg1: f32) -> f32 {
%0 = vector.reduction <add>, %arg0, %arg1 : vector<8xf32> into f32
return %0 : f32
}
```
Now, after this change:
* when lowering the compiler now produces for both strategies in one
step.
```
func.func @rank1_multi_reduction(%arg0: vector<8xf32>, %arg1: f32) -> f32 {
%0 = vector.reduction <add>, %arg0, %arg1 : vector<8xf32> into f32
return %0 : f32
}
```
This pattern is also useful for an ongoing refactoring that is happening
in the multi_reduction patterns. It is the only pattern that increases
multi_reduction in rank and would lead to an infinite loop when
attempting to reach a fixed point once we generalize other unrolling
patterns.

[clang][Modules] Fixing unexpected warnings triggered by a PCH and a module with config macros (#177078)
When a PCH is compiled with macro definitions on the command line, such
as `-DCONFIG1`, an unexpected warning can occur if the macro definitions
happen to belong to an imported module's config macros. The warning may
look like the following:
```
definition of configuration macro 'CONFIG1' has no effect on the import of 'Mod1'; pass '-DCONFIG1=...' on the command line to configure the module
```
while `-DCONFIG1` is clearly on the command line when `clang` compiles
the source that uses the PCH and the module.
The reason this can happen is a combination of two things:
1. The logic that checks for config macros is not aware of any command
line macros passed through the PCH
([here](https://github.com/llvm/llvm-project/blob/7976ac990000a58a7474269a3ca95e16aed8c35b/clang/lib/Frontend/CompilerInstance.cpp#L1562)).
2. `clang` _replaces_ the predefined macros on the command line with the
predefined macros from the PCH, which does not include any builtins
([here](https://github.com/llvm/llvm-project/blob/7976ac990000a58a7474269a3ca95e16aed8c35b/clang/lib/Frontend/CompilerInstance.cpp#L679)).
This PR teaches the preprocessor to recognize the command line macro
definitions passed transitively through the PCH, so that the error check
does not miss these definitions by mistake. The config macro itself
works fine, and it is only the error check that needs fixing.

[lld][Hexagon] Fix findMaskR8 missing duplex support (#183936)
findMaskR8() lacked an isDuplex() check, unlike findMaskR6(),
findMaskR11(), and findMaskR16() which all handle duplex instructions.
When the assembler generates R_HEX_8_X on a duplex SA1_addi instruction
(e.g. `{ r0 = add(r0, ##target); memw(r1+#0) = r2 }`), the wrong mask
0x00001fe0 placed relocation bits at [12:5] instead of [25:20],
corrupting the low sub-instruction (e.g. memw became memb).
Add the isDuplex() check returning 0x03f00000, and add a comprehensive
test covering all duplex instruction x relocation type combinations
across findMaskR6, findMaskR8, findMaskR11, and findMaskR16.

[clang-doc] Add a Mustache Markdown generator (#177221)
Adds a Markdown generator that uses Mustache templates. This patch adds
the templates themselves and implements changes to the JSONGenerator to
allow for the creation of specific files needed by the MD tests like
`all-files.json`.
This backend should be considered experimental. It satisfies all the
same tests that the current MD backend is tested against, but those
don't seem to provide full coverage for all functionality inside that
backend. It also doesn't output everything provided by JSON. It doesn't
use the MD unittests because the Mustache templates must currently be
written to files.

Reverts llvm/llvm-project#125412
See the discussion in #125412 for why this is necessary. The summary is
that:
- Eliding arguments is the C23 extension, but libunwind builds its C
files with `-std=c99`, so this change broke the build.
- `-Wno-unused-parameter` is part of the build for libunwind, so the
codebase does allow them.

marking them as 'const' doesn't add additional information.
Also the diagnostic messages look awkward without a name.

different threads. For example, we allow dynamically loading plugins
from the command interpreter, which in theory could be coming from
different threads.

Allow unsigned immediates that look like like simm10 when only

[652024,65535]. For pli.w, this is [4294966784,4294967295].
Since we're only inserting 16 or 32 bits, it makes sense to me that only
those 16 or 32 bits matter. This is similar to how we allow `li a0,
0xffffffff` on RV32.

[DebugInfo][DwarfDebug] Move emission of globals from beginModule() to endModule() (5/7) (#184219)
RFC
https://discourse.llvm.org/t/rfc-dwarfdebug-fix-and-improve-handling-imported-entities-types-and-static-local-in-subprogram-and-lexical-block-scopes/68544
This patch moves the emission of global variables from
`DwarfDebug::beginModule()` to `DwarfDebug::endModule()`.
It has the following effects:
1. The order of debug entities in the resulting DWARF changes.
2. Currently, if a DISubprogram requires emission of both concrete
out-of-line and inlined subprogram DIEs, and such a subprogram contains
a static local variable, the DIE for the variable is emitted into the
concrete out-of-line subprogram DIE. As a result, the variable is not
available in debugger when breaking at the inlined function instance.
It happens because static locals are emitted in
`DwarfDebug::beginModule()`, but abstract DIEs for functions that are
not completely inlined away are created only later during
`DwarfDebug::endFunctionImpl()` calls.
With this patch, DIEs for static local variables of subprograms that
have both inlined and the concrete out-of-line instances are placed into
abstract subprogram DIEs. They become visible in debugger when breaking
at concrete out-of-line and inlined function instances.
`llvm/test/DebugInfo/Generic/inlined-static-var.ll` illustrates that.
3. It will allow to simplify abstract subprogram DIEs creation by
reverting https://github.com/llvm/llvm-project/pull/159104 later.
This is needed to simplify DWARF emission in a context of proper support
of function-local static variables which comes in the next patch
(https://reviews.llvm.org/D144008), making all function-local entities
handled in `DwarfDebug::endModuleImpl()`.

[WebAssembly] MC support for acquire-release atomics (#183656)
Initial support for acquire-release atomics, specified as part of
https://github.com/WebAssembly/shared-everything-threads
This adds an ordering operand to atomic loads, stores, RMWs,
wait/notify,
and fences. It currently defaults to 0 and ISel is not updated yet, so
atomics produced by the compiler will still always be seqcst.
Asm parsing and printing, binary emission and disassembly are all
updated. Binary emission will always use the old encoding because the
encoding is smaller, and to get backwards compatibility for free.

[dsymutil] Add option to filter debug map objects by allow/disallow-list (#182083)
# Motivation
When using `dsymutil` to generate dSYM for large binaries, sometimes we
want to keep only some of the object files. This has the benefits of
reduced dSYM size and improved performance of LLDB and other tools which
consume the dSYM.
The current way to achieve this is to use YAML input (the `dsymutil -y`
option). However, it doesn't really solve the problem:
1. The whole debug map has to be parsed somewhere else first, before
filtered down to the wanted parts.
2. Said info is written then read by `dsymutil`. The I/O is redundant.
# Change
This patch propose a new way, by adding new options (`dsymutil --allow
<path>` and `--disallow <path>`), which will only process object files
that pass the allow/disallow list.
Important details:
* The input file is YAML. See test files for format.
* Currently, only object files are filtered. The design allows to extend
the filtering to other aspects of the debug map in the future (e.g.
functions).
* If `--oso-prepend-path` is specified, it applies to the entries in the
input file. I.e. Entries in the input file should exact match that of
N_OSO entries.

[lld][WebAssembly] Convert weak-alias tests to assembly. NFC (#184667)
This actually both improves and simplifies the `Inputs/weak_alias`. With
the `.ll` version we ended up using memory and `__stack_pointer` and
locals, but LLVM ended up generated `call` rather than `call_indirect`
for the `call_alias_ptr` and `call_direct_ptr`. With the assembly tests
we can ensure the usage of `call_indirect` while avoiding all the other
stuff.

[CIR] Upstream global variable replacement (#184686)
This change upstreams the CIR implementation of global variable
replacement. When we get a call to get or create a global variable using
a type that does not match the previous type for a variable of the same
name, we need to replace the old definition with the new one. In classic
codegen that was as simple as replaceAllUses+eraseFromParent, but in CIR
because we have typed pointers, we need to visit the uses and update
them with bitcasts to reflect the new type.

[Clang] Only define `wchar_size` module flag if non-standard (#184668)
Summary:
This PR simply changes the behavior of the `wchar_size` flag. Currently,
we emit this in all cases for all targets. This causes problems during
LLVM-IR linking, specifically because this would vary between Linux and
Windows in unintuitive ways. Now we have an llvm::Triple helper to
determine the size from the known values. The module flag will only be
emitted if these do not match (indicating a non-standard environment).
In addition to fixing AMDGCN bitcode linking, this also means we don't
need to bloat *every* IR module compiled by clang with this flag. The
changed tests reflects this, one less unnecessary piece of metadata.

On ppc64le, children are not produced for DW_TAG_subprogram "main" in
this test. Therefore, dwarfdump doesn't print NULL after this tag. On
other platforms (AArch64/X86), DW_TAG_subprogram has DW_TAG_variable
"instance_C", which should not be matched by the check lines.
Loosened the check lines (turned CHECK-NEXT into CHECK) to make them
work for all mentioned platforms.

Model strings without any randomness marker characters (`%`), which
results in a unique path that's not at all unique. To avoid this
foot-gun, we now assert that the model contains at least one, and update
all the broken usages accordingly.

My change to remove an incorrect DWARF register number for

generic reg type in the definitions of cpsr.
We need to have a macro (DEFINE_MISC_REGS) for status/control
registers that have no DWARF/eh_frame and no generic reg num.
I added a new macro, DEFINE_GPR_CPSR, for cpsr which is unique
in having no DWARF/eh_frame numbers but does have a generic
flags reg number.

[SafeStack] Fix crashing with scalable TypeSizes (#180547)
On e.g. aarch64 the TypeSize of scalar types can have a size that is not
known at compile time.
Currently when safestack occurs those it simply crashes as described in
https://github.com/llvm/llvm-project/issues/175868.
Since we cannot verify the size at compile time we simply consider the
access to be unsafe (in regards to safestack).
Reproducer:
```
#include <arm_sve.h>

svst1_s32(svptrue_b32(), buffer, res);

[AMDGPU] Optimize S_SETREG_IMM32_B32 piggybacking by treating it as a mode scope boundary (#184703)
When `handleSetregMode` encounters an `S_SETREG_IMM32_B32` with `Size <=
12`, the instruction's `imm32[12:19]` bits are "free" for VGPR MSB
piggybacking. Previously, the old mode was eagerly written into these
bits, but the `Rewritten` guard in `setMode` would then block subsequent
piggybacking when the next VGPR instruction needed a different mode,
causing an unnecessary `S_SET_VGPR_MSB` to be emitted.
Model the `S_SETREG_IMM32_B32` as the boundary of the old mode's control
range: reset `CurrentMode` and clear `bits[12:19]` to zero. This lets
the next `setMode` call freely piggyback the required mode without
triggering `Rewritten`.

[MLIR][Vector] Fix crash in operatesOnSuperVectorsOf on rank-mismatched shaped (#183967)
The `operatesOnSuperVectorsOf` function in VectorUtils.cpp contained an
assertion that fired when a `vector.transfer` operation's vector type
had a different rank (or non-divisible shape) from the sub-vector type
supplied by the caller:
assert((ratio || \!mustDivide) &&
"vector.transfer operation in which super-vector size is not an"
" integer multiple of sub-vector size");
This assertion was incorrect because the function's callers (e.g., the
affine super-vectorizer) legitimately pass transfer ops whose vector
type doesn't match the requested sub-vector shape. In those cases the
correct answer is simply that the op does not operate on a super-vector
of that sub-vector type, so `operatesOnSuperVectorsOf` should return
`false`.
Remove the assert return `false` when `computeShapeRatio` produces no
result, and remove the now-unused `mustDivide` variable.

[mlir][spirv] Fix crash in FuncOpVectorUnroll for dynamic-shaped tensor args (#184626)
FuncOpVectorUnroll::matchAndRewrite iterates over all function arguments
and creates a zero-constant placeholder for any non-vector argument via
rewriter.getZeroAttr(type). For dynamically-shaped tensor types such as
tensor<?x2xi8>, getZeroAttr ultimately calls
DenseIntOrFPElementsAttr::getRaw which asserts that the type has a
static shape.
Add an early pre-check that returns failure() for any non-vector
argument with a dynamically-shaped type. This must be done before any IR
modifications are made, since returning failure() after inlining the
function body would leave the IR in an inconsistent state.

[flang-rt] Fixes EXECUTE_COMMAND_LINE() status management and double buffering (#184285)
EXECUTE_COMMAND_LINE() without CMDSTAT initiated termination in runtime
if the command returned non-zero status code. For example,
EXECUTE_COMMAND_LINE('false') on Linux would cause "fatal Fortran
runtime error... : Command line execution failed with exit code: 1."
This is too strict: EXECUTE_COMMAND_LINE() successfully called 'false',
it's just 'false' happened to return non-zero status code. ifx and
gfortran don't initiate termination in such case. Changed
EXECUTE_COMMAND_LINE() implementation to behave in similar fashion.
Also during testing discovered that when the output of the program that
uses EXECUTE_COMMAND_LINE(... WAIT=.false.) is piped to a file, the
resulting file has duplicated output lines. This was because fork()
command also ends up duplicating parent's buffered output to the child.
Added flush of all units and C stdio before calling fork().

[RISCV] Remove RISCVVectorPeephole::tryToReduceVL (#184297)
Now that RISCVVLOptimizer has been extended to handle the remaining
cases tryToReduceVL handles, we can remove tryToReduceVL to keep all the
reduction logic in one place.
Intended to be NFC but it looks like in
test/CodeGen/RISCV/rvv/fixed-vectors-insert-subvector-shuffle.ll we were
previously reducing the vl of a volatile load in
insert_subvector_dag_loop, which RISCVVLOptimizer knows to avoid.
On llvm-test-suite and SPEC CPU 2017 -march=rva23u64 -O3 there are no
changes with this patch.

Without this patch:
- RefKind output doesn't show RefKind::Call bit.
- RefKind::Call isn't included in RefKind::All.
I don't think these changes require additional tests, as the problems
above mainly appear during testing/debugging (e.g. if in tests
comparison of two RefKinds fails, `Call` isn't shown in the output even
if this bit is set).

[mlir][MemRef] Add position-based matching heuristics for rank-reduction with dynamic strides (#184334)
When multiple source dimensions have multiple unit dimensions,
stride-based disambiguation can be wrong with dynamic strides. Add
position-based matching: for each result dimension in order, pick the
leftmost unmatched source dimension with the same size; unmatched source
dims are dropped.
Example: subview from memref<1x8x1x3> to memref<1x8x3>. Both dim 0 and
dim 2 have size 1. Stride-based logic cannot distinguish when strides
are dynamic. Position-based matching correctly drops dim 2 (middle unit
dim) instead of dim 0.
When we have non-trivial static strides, we make use of the stride-based
logic, else we fall back to position-based logic as introduced by this
patch.
INPUT :-
```
func.func @fold_rank_reducing_subview_1x8x1x3_to_1x8x3_drop_middle_unit_dim(
%arg0 : memref<?x?x?x?xf32, strided<[?, ?, ?, ?], offset: ?>>,
%arg1 : index, %arg2 : index, %arg3 : index, %arg4 : index) -> f32 {
%c0 = arith.constant 0 : index
%0 = memref.subview %arg0[0, 0, 0, 0][1, 8, 1, 3][1, 1, 1, 1]
: memref<?x?x?x?xf32, strided<[?, ?, ?, ?], offset: ?>> to
memref<1x8x3xf32, strided<[?, ?, ?], offset: ?>>
%1 = memref.load %0[%c0, %arg1, %arg2] : memref<1x8x3xf32, strided<[?, ?, ?], offset: ?>>
return %1 : f32
}
```
WITHOUT this patch we get :-
```
memref.load %0[%c0, %c0, %arg1, %arg2]
```
WITH this patch we get :-
```

[MLIR][NVVM] Unify and move to a single tcgen05_mma_kind attr for all tcgen05.mma Ops (#184433)
This change unifies using of `tcgen05_mma_kind` attribute for
tcgen05.mma Ops in MLIR.
Before this change there were two block scale attributes used for
tcgen05.mma Ops. One was `MMABlockScaleKindAttr` with `mxf8f6f4`, `mxf4`
and `fxf4nvf4` values used for `tcgen05.mma.block_scale` and
`tcgen05.mma.sp.block_scale`. Another one was `Tcgen05MMAKindAttr` with
`f16`, `tf32`, `f8f6f4` and `i8` values used for `tcgen05.mma`,
`tcgen05.mma.sp`, `tcgen05.mma.ws` and `tcgen05.mma.ws.sp`.
`Tcgen05MMAKindAttr` has been extended with values from
`MMABlockScaleKindAttr`. Now there is `tcgen05_mma_kind` attribute only
for all `tcgen05.mma` Ops in MLIR.
Backward compatibility is not supported. Existing tests and scripts
should be updated to use `tcgen05_mma_kind` attribute instead of
`block_scale_kind` for all tcgen05.mma MLIR Ops.

[SystemZ] Mark fminimumnum/fmaximumnum as legal (#184595)
In M=4 mode, the behavior matches IEEE 754-2019 minimumNumber, except
that if both operands are sNaN, the result will be sNaN rather than
qNaN. However, this is explicitly allowed for LLVM's minimumnum
intrinsic, as canonicalization can be omitted for non-constrainted FP.
As such, mark fminimumnum/fmaximumnum as legal, and lower them the same
way as fminnum/fmaxnum. In the future, we may wish to switch those to
use M=0 instead, to match IEEE 754-2008 maxNum/minNum instead.

[VPlan] Move tail folding out of VPlanPredicator. NFC (#176143)
Currently the logic for introducing a header mask and predicating the
vector loop region is done inside introduceMasksAndLinearize.
This splits the tail folding part out into an individual VPlan transform
so that VPlanPredicator.cpp doesn't need to worry about tail folding,
which seemed to be a temporary measure according to a comment in
VPlanTransforms.h.
To perform tail folding independently, this splits the "body" of the
vector loop region between the phis in the header and the branch + iv
increment in the latch:
Before:
```
+-------------------------------------------+
|%iv = ... |
|... |
|%iv.next = add %iv, vfxuf |
|branch-on-count %iv.next, vector-trip-count|
+-------------------------------------------+
```
After:
```
+-------------------------------------------+
|%iv = ... |
|%wide.iv = widen-canonical-iv ... |
|%header-mask = icmp ule %wide.iv, BTC |---+
|branch-on-cond %header-mask | |
+-------------------------------------------+ |
| |
v |
+-------------------------------------------+ |
|... | |
+-------------------------------------------+ |
| |
v |
+-------------------------------------------+ |
|%iv.next = add %iv, vfxuf |<--+
|branch-on-count %iv.next, vector-trip-count|
+-------------------------------------------+
```
Phis are then inserted in the latch for any value in the loop body that
have outside uses, with poison as their incoming value from the header
edge.
The motivation for this is to allow us to share the same "predicate all
successor blocks" type of predication we do for tail folding, but for
early-exit loops in #172454. This may also allow us to directly emit an
EVL based header mask, instead of having to match + transform the
existing header mask in addExplicitVectorLength.
This also allows us to eventually handle recurrences in the same
transform, avoiding the need to special case tail folding in
addReductionResultComputation.

performs a floating-point addition between two operands. `nvvm.subf`
performs a floating-point subtraction between two operands and is
equivalent to an `llvm.fneg` followed by an `nvvm.addf` operation.

[SDAGBuilder] Fix incorrect fcmp+select to minnum/maxnum transform (#184590)
minnum/maxnum don't have the correct sNaN semantics, we must convert to
minimumnum/maximumnum instead.
To avoid an NVPTX regression, make it handle fmaximmumnum in one
TableGen pattern.
This is intended as a targeted fix for the miscompile, as the complete
removal of this transform (#93575) appears to be blocked.
Fixes https://github.com/llvm/llvm-project/issues/176624.

[AArch64] Fix SVE cost model for various math intrinsics (#184358)
The implementation of getIntrinsicInstrCost in BasicTTIImpl
assumes that for some intrinsics if we're using custom
lowering for the equivalent DAG node that the cost needs to
be 2, instead of 1 for legal ops. However, even though we
use custom lowering for these scalable vector operations
when SVE is available, we still end up generating the same
efficient codegen as fixed-width. This patch deals with a
few obvious intrinsics that we know get lowered to something
sensible and return the same cost as NEON, i.e. 1.

[AArch64] Fold zero-high vector inserts in MI peephole optimisation (#182835)
Summary
This patch follows on from #178227.
The previous ISel fold lowers the 64-bit case to:
```
fmov d0, x0
fmov d0, d0
```
which is not ideal and could be fmov d0, x0.
A redundant copy comes from the INSERT_SUBREG/INSvi64lane.
This peephole detects <2 x i64> vectors made of a zeroed upper and low
lane produced by FMOVXDr/FMOVDr, then removes the redundant copy.
Further updated tests and added MIR tests.

[mlir][sparse] Fix crash in SparseAssembler when run after SparseTensorCodegen (#183896)
After --sparse-tensor-codegen, sparse tensor arguments are replaced by
memrefs and \!sparse_tensor.storage_specifier types. The subsequent
--sparse-assembler pass calls getSparseTensorEncoding() to identify
sparse arguments to wrap/unwrap. However, getSparseTensorEncoding()
returns non-null for StorageSpecifierType as well as for sparse
RankedTensorType. Since StorageSpecifierType is not a RankedTensorType,
the subsequent cast<RankedTensorType> in convTypes() and convVals()
would crash with an assertion failure.
Fix by also checking isa<RankedTensorType>(type) in the passthrough
condition in both convTypes() and convVals(), so that
StorageSpecifierType arguments pass through unchanged.

[mlir][sparse] Fix crash in sparsification when unary/binary present block captures sparse tensor argument (#184597)
`relinkBranch` in Sparsification.cpp assumed that any block argument
from the outer `linalg.generic` op encountered inside an inlined
semi-ring branch must be a dense tensor, and asserted accordingly.
However, the `present` block of a `sparse_tensor.unary` (or similar
semi-ring ops) is permitted to capture sparse tensor operands directly
via `isAdmissibleBranchExp`, which accepts any `BlockArgument` as
admissible.
The fix removes the incorrect assertion and extends the load generation
to handle sparse tensors using `genSubscript`, which already knows how
to return the value buffer and current value position via the loop
emitter. The `kSparseIterator` strategy (where `genSubscript` returns a
`TensorType`) is also handled by emitting a
`sparse_tensor.extract_value` op.
Fixes #91183

[mlir][bytecode] Fix crash when reading DenseIntOrFPElementsAttr with unsupported element type (#184773)
When a bytecode type callback substitutes a type that does not implement
DenseElementTypeInterface (e.g., \!test.i32 replacing i32), the bytecode
reader attempted to reconstruct a DenseIntOrFPElementsAttr with that
type. This unconditionally called getDenseElementBitWidth() which hit an
llvm_unreachable on unsupported types.
Fix this by validating the element type implements
DenseElementTypeInterface in readDenseIntOrFPElementsAttr before
proceeding. If the check fails, a proper diagnostic is emitted and
reading fails gracefully instead of crashing.

[mlir][Shape] Fix crash in BroadcastOp::fold when operand is ub.poison (#183931)
BroadcastOp::fold used an unchecked llvm::cast<DenseIntElementsAttr> on
each operand's folded attribute. The existing null-check only guarded
against a missing (unset) attribute, not against a non-null attribute of
a different type such as PoisonAttr (produced when an operand is
ub.poison).
Replace the unchecked casts with dyn_cast_or_null, bailing out with
nullptr (i.e. no fold) when any operand does not provide a
DenseIntElementsAttr.
Add a regression test with a ub.poison operand.

[mlir][bufferization] Fix use-after-free in ownership-based buffer deallocation (#184118)
When `handleInterface(RegionBranchOpInterface)` processes an op such as
`scf.for`, it calls `appendOpResults` to clone the op with extra
ownership result types and erase the original. The `Liveness` analysis
is computed once before the transformation begins and may still
reference the old (now-freed) result values.
If the same block contains a `BranchOpInterface` terminator (e.g.,
`cf.br`) after the structured loop, `handleInterface(BranchOpInterface)`
calls `getMemrefsToRetain`, which iterates `liveness.getLiveOut()`. That
set may contain stale `Value` objects pointing to the erased op's
results. Calling `isMemref()` on such a value dereferences freed memory,
triggering a crash.
Fix by adding a `valueMapping` map to `DeallocationState`. Before
erasing the old op in `handleInterface(RegionBranchOpInterface)`, record
the old-to-new result mapping via `state.mapValue`. The
`getLiveMemrefsIn` and `getMemrefsToRetain` helpers translate stale
liveness values through this map before calling `isMemref`, so they
always operate on live pointers.

[VPlan] Replicate VPScalarIVStepsRecipe by VF outside replicate regions. (#170053)
Extend replicateByVF to also handle VPScalarIVStepsRecipe. To do so, the
patch adds a new lane operand to VPScalarIVStepsRecipe, which is only
added when replicating. This enables removing a number of lane 0
computations. The lane operand will also be used to explicitly replicate
replicate regions in a follow-up.

[flang][OpenMP] Fix crash when a sliced array is specified in a forall within a workshare construct (#170913)
This is a fix for two problems that caused a crash:
1. Thread-local variables sometimes are required to be parallelized.
Added a special case to handle this in
`LowerWorkshare.cpp:isSafeToParallelize`.
2. Race condition caused by a `nowait` added to the `omp.workshare` if
it is the last operation in a block. This allowed multiple threads to
execute the `omp.workshare` region concurrently. Since
_FortranAPushValue modifies a shared stack, this concurrent access
causes a crash. Disable the addition of `nowait` and rely on the
implicit barrier at the the of the `omp.workshare` region.

[mlir][CFGToSCF] Fix crash when encountering unknown control flow ops (#184103)
When transformToStructuredCFBranches encountered a control flow op not
handled by the CFGToSCFInterface (e.g., spirv.BranchConditional with
--lift-cf-to-scf), it correctly emitted an error and returned failure.
However, blocks had already been moved from the parent region into
temporary local Region objects before the failure was detected.
When those temporary Region objects went out of scope, their destructor
tried to destroy the contained blocks. But those blocks still had live
predecessor references from the parent region (the regionEntry's
terminator still pointed to them), causing an assertion failure:
use_empty() && "Cannot destroy a value that still has uses\!"
Fix: on failure from createStructuredBranchRegionOp, move the blocks
from the temporary conditionalRegions back into the parent region before
returning failure. This restores IR consistency and allows the Region
destructor to run safely.

[CIR] Fix void ternary operators- (#184691)
I discovered this while working on something else, but we were doing a
'getTerminator' on a block that we didn't know whether it had a
terminator, and MLIR causes an assert in this case. This patch
re-factors the code to better check whether it might have a terminator
(to assuage the assert in mlir::Block), and get the correct value out.
The fixup later in the ternary setup correctly gets the 'void' yields
correct, so everything else gets fixed eventually.

[Flang][OpenMP] Skip intermediate map generation for motion modifier map directives (#177737)
Currently if we create the following map:
!$omp target update from/to(derived_type%allocatable)
We'll generate an extra map for the derived type (and any other
allocatable maps that may be in-between the final mapped allocatable
member). However, for cases like this, and other motion modifier related
map directives we don't need to do so. All the user cares about is the
specified member. Removing the intermediate member will minimize extra
performance overhead. It also maintains correctness, as currently, the
MLIR diagnostics for the motion modifiers restricts possible map types
for updates to to and from, and applying this map type to an
intermediate map will result in unintended side affects, e.g. mapping
back data the user didn't want to or over-writing data they didn't
intend to on device. This minor modification addresses that.

COFF: Allow hex literals in .def files: BASE/HEAPSIZE/STACKSIZE (#184764)
For a Win32 DLL, a .def file can have a custom executable base:
```
LIBRARY "stub.dll" BASE=0x10000000
```
Currently the parser enforces Base 10, but [Microsoft's
documentation](https://learn.microsoft.com/en-us/cpp/build/reference/rules-for-module-definition-statements?view=msvc-170)
states "Numeric arguments are specified in base 10 or hexadecimal".
This fixes that, and also HEAPSIZE and STACKSIZE (which use the same
function).
There are a few more instances of `getAsInteger` that expect base10 -
for ordinals and the VERSION directive. Since I don't have an
in-the-wild example of a .def file using hexadecimal for these, I am
wary about changing those too.

[mlir][memref] Fix crash in DimOp::fold for subview with ambiguous dropped dims (#183995)
When a rank-reducing subview has multiple size-1 source dimensions and
all strides are dynamic, `computeMemRefRankReductionMask` cannot
unambiguously determine which dimension is dropped. It would fall back
to an arbitrary choice that could be wrong.
In `DimOp::fold`, the code then maps a result dimension to that
(possibly incorrect) source dimension and asserts
`isDynamicSize(sourceIndex)`. If `getDroppedDims()` picked the wrong
dropped dim, the source dim at `sourceIndex` may be statically sized,
causing the assertion to fire.
Fix this by replacing the assert with a guard that returns `{}` (no
fold) when the resolved source dimension is not dynamic. This is safe
because the fold already handles the statically-sized result case
earlier.
Fixes #111244

[MLIR][XeGPU] Decompose unsupported 'vector.transfer_read'-transpose-permutations (#182875)
The PR adds a pattern to `vector-to-xegpu` pass that decomposes
`vector.transfer_read` with unsupported transpose-permutations
(unsupported element-type) into `vector.transfer_read +
vector.transpose`:
Example:
```mlir
// input-ir:
%0 = vector.transfer_read %source[%offset, %offset], %c0
{permutation_map = affine_map<(d0, d1) -> (d1, d0)>,
in_bounds = [true, true]} : memref<32x64xf16>, vector<8x16xf16>
// mlir-opt %s --convert-vector-to-xegpu
// before PR (no conversion because of unsupported type):
%0 = vector.transfer_read %source[%offset, %offset], %c0
{permutation_map = affine_map<(d0, d1) -> (d1, d0)>,
in_bounds = [true, true]} : memref<32x64xf16>, vector<8x16xf16>
// mlir-opt %s --convert-vector-to-xegpu
// after PR (decomposed + converted):
%0 = xegpu.load_nd %source[%offset, %offset]
%1 = vector.transpose %0
```

[MLIR][XeGPU] Support vector.contract transpose_a/transpose_b via 'vector-to-gpu' patterns (#182885)
The PR adds [`vector.contract(transpose_a/transpose_b)` decomposition
patterns](https://github.com/llvm/llvm-project/blob/3215645b8d81bbef7db1d16b88de7ed0288f2274/mlir/lib/Conversion/VectorToGPU/VectorToGPU.cpp#L1263)
from `vector-to-gpu` to `vector-to-xegpu` pass.
The `populatePrepareVectorToMMAPatterns` adds two patterns:
1. `PrepareContractToGPUMMA` that splits `vector.contract(transpose)`
into `vector.transpose + vector.contract`
2. `CombineTransferReadOpTranspose` that fuses `vector.transpose` into
the permutation map of `vector.transfer_read`
The second pattern doesn't always bring us to the desired result
(`xegpu.load_nd + vector.transpose + xegpu.dpas`) since [not all data
types are supported
](https://github.com/llvm/llvm-project/blob/1237bd6df05a4777f444677186e4814388916ea9/mlir/lib/Conversion/VectorToXeGPU/VectorToXeGPU.cpp#L570-L575)
for the transposed-read case. There's a second PR (#182875) on this
matter that adds a decomposition-pattern for unsupported types (it might
seem strange that we first fuse and then decompose
transfer_read+transpose but this way we don't have code duplication
between vector-to-gpu&to-xegpu passes and cover all functional cases)

Add the ability to "allow another thread to see the private state" mode. (#184272)
When lldb stops to run a breakpoint condition or other callback that has
to happen between the private stop and returning control to the user, it
will run in the state where the public state is still "running". But if
the callback needs to run lldb commands or python code, it needs to see
the correct "stop" state.
We used to handle that by switching the public state to stopped before
running the callbacks. However, that opened a window where we are still
handling the stop event and another thread would be allowed to continue
the target or do other actions that can interfere with that orderly
process.
This patch adds the ability to designate a particular thread as "seeing
the private state" while all other threads see the "public state". Then
when we run a breakpoint callback, no threads but the one that is
actually running the callback will see the state change until the event
has been delivered to the primary state listener.
It also adds a test that while a long-running breakpoint callback runs,
another thread continues to see the state as running.

[MC] Merge fixupNeedsRelaxation and fixupNeedsRelaxationAdvanced. NFC (#184832)
The two-tier relaxation hook design (fixupNeedsRelaxationAdvanced
delegating to fixupNeedsRelaxation) is confusing and unnecessary.
Only M68k and AMDGPU used fixupNeedsRelaxation (via the default
fixupNeedsRelaxationAdvanced). AArch64 and CSKY had dead overrides:
they don't override mayNeedRelaxation to ever return true.
Merge the two hooks: convert M68k and AMDGPU to override
fixupNeedsRelaxationAdvanced directly, remove dead overrides from
AArch64 and CSKY, and simplify the default implementation to
`return !Resolved`.

[SelectionDAG] Fix cycle in ReplacedValues during type legalization (#184697)
During type legalization, `ReplaceValueWith` handles morphed nodes by
computing `OldValId` and `NewValId`, calling `ReplaceAllUsesOfValueWith`
(RAUW), then adding `ReplacedValues[OldValId] = NewValId`.
However, the RAUW call can trigger `CSE`, which fires NoteDeletion
callbacks that add new entries to `ReplacedValues`. If NoteDeletion adds
`ReplacedValues[A] = B`, and the subsequent assignment adds
`ReplacedValues[B] = A`, a cycle is created. RemapId then recurses
infinitely following the cycle during path compression, causing a stack
overflow crash.
On AArch64, i16 is not a legal type and requires promotion to i32. When
IR uses i16 values as `extractelement` indices that feed into other
`extractelement` operations, the interplay between result promotion and
operand promotion creates the specific CSE pattern that produces the
cycle.
Fix by calling RemapId on both OldValId and NewValId after the RAUW call
to account for new ReplacedValues entries added during the RAUW cascade.
In the reproducer, this causes both ids to resolve to the same value,
skipping the assignment and preventing the cycle.

[HLSL][Matrix] Add APValue and ConstExpr evaluator support for matrices (#178762)
Fixes #168935
This PR adds basic support for matrix APValues and a ConstExpr evaluator
for matrices.
- ConstExpr evaluation changes:
- Matrix initializer list
- Matrix HLSL elementwise cast
- Matrix HLSL aggregate splat
- Vector HLSL matrix truncation
- Int HLSL matrix truncation
- Float HLSL matrix truncation
- Matrix APValue:
- AST dumper and serialization
- Value flattening
Note that APValue matrices hold its elements in row-major order
irrespective of the `-fmatrix-memory-layout` flag.
The `-fmatrix-memory-layout` is for codegen, not semantics, so the
decision of which memory layout to use for the matrix APValue can be
independent of the memory layout for codegen.
There are also a number of places expecting switch case coverage over
all APValues but which do not currently support matrix APValues. I have
added placeholder llvm_unreachables to these places for the matrix
APValue, as these places can not currently be exercised in clang tests
(AFAIK).

[clang][deps] Simplify by-module-name scan API (#184376)
The by-module-name scanning APIs are fairly spread out. There's the main
`CompilerInstanceWithContext` class that provides a constructor,
`initialize()` and `computeDependencies()`. Then there's the
`DependencyScanningWorker` that optionally owns
`CompilerInstanceWithContext` and re-exposes two `initialize()` and one
`computeDependencies()` functions. Lastly, there's
`DependencyScanningTool` that again re-exposes two variants of
`initialize()` and one `computeDependencies()`.
The current setup makes it unnecessarily difficult to make changes to
these APIs (as observed in
https://github.com/swiftlang/llvm-project/pull/12453).
This PR makes `CompilerInstanceWithContext` standalone, and hides the
construct + initialize pattern behind a static factory function. This
makes it harder to misuse the API (forgetting to call `initialize()`,
calling it twice, etc.) and means changes now need to only touch single
class instead of three classes spread over multiple files.

[libc] Rework slab cache data structure for GPU allocator
Summary:
This was previously a Trieber stack, which is a perfectly fine generic
and lock-free data structure. However, this used some expensive CAS
operations and had issues with ABA. Because the only user of this was
the slab cache mechanism, we can pretty safely specialize it. Instead,
we simply search a fixed size buffer for some sentinal values and CAS
into it.
For allocations that only ever hit the cache, this improves performance
from ~9000 cycles to ~6000 cycles and similar improvements for workloads
that feel the pain of small thread counts hitting the cache.

[clang][bytecode][HLSL][Matrix] Support `ConstantMatrixType` and more HLSL casts in the new constant interpreter for basic matrix constexpr evaluation in HLSL (#184840)
Forgot to change the target branch before merging. This PR is a
cherry-pick of the squashed-and-merged PR commit
b16aa4b7ec665911c74300cd7442659b70973d13 from 183424
This PR fixes #182963
This PR is an extension of #178762 which has already been merged.
This PR adds support for `ConstantMatrixType` and the HLSL casts
`CK_HLSLArrayRValue`, `CK_HLSLMatrixTruncation`,
`CK_HLSLAggregateSplatCast`, and `CK_HLSLElementwiseCast` to the
bytecode constexpr evaluator.
The implementations of CK_HLSLAggregateSplatCast and
CK_HLSLElementwiseCast are incomplete, as they still need to support
struct and array types to enable use of the experimental new constant
interpreter on other existing HLSL constexpr tests. The completion of
the implementations of these casts will be tracked in a separate issue
(#183426) and implemented in a separate PR.

[flang][OpenMP] Utilities to get uppercase directive/clause names (#184853)
It is a convention to use uppercase names of directives and clauses in
diagnostic messages, but getting such names is somewhat cumbersome:
```
parser::ToUpperCaseLetters(llvm::omp::getOpenMPDirectiveName(dirId));
parser::ToUpperCaseLetters(llvm::omp::getOpenMPClauseName(clauseId));
```
Implement `GetUpperName` (overloaded for clauses and directives) to
shorten it to
```
GetUpperName(dirId, version);
GetUpperName(clauseId, version);
```
This patch replaces existing instances of this pattern, adding the use
of OpenMP version where it was previously missing.

Fixes #168944
Depends on #178762 being merged first.
The commit adds implicit conversion warnings for HLSL matrix types in
Clang's semantic checker by extending SemaChecking.cpp to detect
precision loss when converting between matrix types (specifically,
ConstantMatrixType).
A new test validates float precision warnings, and an existing test was
updated to expect the new diagnostics.

Module maps found via `-fmodule-map-file=` are not a problem because
they are all loaded at the start of translation.

We only support splat shift amounts. Previously we checked if the shift

I don't think there is a guarantee that the splat_vector will stick
around as a splat_vector. It's safer if we capture the splat and create
a dedicated node with a scalar shift amount.

This reverts commit 7ad2c6db54a0e77249f2edb3c589ccf4c930d455.
PR #183395 introduced the `exact` flag to `index_cast` and
`index_castui` and updated some canonicalization patterns.
These canonicalization patterns were found to be unsound. For example:
* `index_cast(index_cast(x)) -> x`
* where one first truncates and then widens x
the rewrite is unsound because information is lost on the first cast as
it **may** truncate the value of x, therefore losing information. The
`exact` flag was made to make this transformation sound. Its semantics
are that when the `exact` flag is present, then it is assumed that the
operand to index_cast does not lose information (i.e., fits perfectly in
the destination type).
In PR #183395, the canonicalization rule was rewritten such that would
only match where the inner index_cast had the `exact` flag set.
* `index_cast(index_cast(x, exact)) -> x`
* where source type and destination type are the same
A post-merge review
[highlighted](https://github.com/llvm/llvm-project/pull/183395#discussion_r2880422529)
that the pattern above also disallows the following correct pattern:
* `index_cast(index_cast(x)) -> x`
* when the first index widens and the second one truncates.
Unfortunately the semantics of `index` are such that its bitwidth is
target specific. Attempts were made in
https://github.com/llvm/llvm-project/pull/184631 to automatically add
annotations were possible but no agreement was reached on the best way
to do this. Adding to the disagreement are the following points:
* [there are other unsound patterns that assume index is
64](https://github.com/llvm/llvm-project/pull/184631/changes#r2885181291)
* [The semantics of index is
contested](https://discourse.llvm.org/t/index-type-and-assumption-about-bitwidth/88287)
This lead to the belief that a reversal and an RFC would be a good
approach to get some consensus from the community before proceeding
further.

Introduce two new codegen operations to the acc dialect that model GPU
compute region execution and parallel launch configuration:
- acc.par_width: specifies a parallel dimension.
- acc.compute_region: wraps a region of code for GPU execution,
capturing
launch configuration (from acc.par_width results) and input values as
block arguments.
These operations bridge the gap between high-level OpenACC compute
constructs (acc.parallel, acc.kernels, acc.serial) and gpu.launch. The
passes that do these transformations will soon follow.

[Clang][CIR][AArch64] NFC: Cleanups in AArch64 builtins lowering (#184404)
This patch performs small cleanups and fixes in the AArch64 builtins
lowering code, with the goal of aligning the CIR path more closely
with the existing Clang CodeGen implementation.
Changes include:
* Make sure that `noundef` is consistently matched using `{{.*}}`.
* Rename `AArch64BuiltinInfo` to `armVectorIntrinsicInfo` for better
consistency with the original CodeGen implementation.
* Simplify `emitAArch64CompareBuiltinExpr`, fix an incorrect
assert condition (missing `!`) and make sure to use the input `kind`
condition instead of hard-coding `cir::CmpOpKind::eq`.
* Improve and clarify comments.
No functional changes intended (NFC).

[flang][acc] Handle ViewLike ops with OutlineRematerializationOpInterface in OffloadLiveInValueCanonicalization (#184218)
`fir::ConvertOp` implements both `ViewLikeOpInterface` and
`OutlineRematerializationOpInterface`. `fir.convert` is also used for
ptr-to-int conversions like `(!fir.ref<i32>) -> i64`. That is not really
a "view" — it converts a pointer to an integer — but
`ViewLikeOpInterface` is still attached, so `getOriginalValue` traces
through it to the underlying value.
When the underlying value is not a rematerialization candidate (e.g.,
`fir.alloca`, a block argument, or a `fir.call` result),
`isRematerializationCandidate` returns false and the `fir.convert` is
left as a live-in. This prevents `ACCImplicitData` from tracing back to
the original pointer to create the data mapping.
This PR:
1. Registers `fir::ConvertOp` with
`OutlineRematerializationOpInterface`.
2. Adds a fallback in `isRematerializationCandidate`: when the traced
original op is not a candidate, check the direct defining op (the
`fir.convert` itself) for `OutlineRematerializationOpInterface`.
```fortran
subroutine test()
integer :: x
!$acc declare create(x)
!$acc parallel
x = 1
!$acc end parallel
end subroutine
```
Before: CSE merges `fir.convert` outside the region; `ACCImplicitData`
cannot map the pointer.
After: `fir.convert` is sunk/rematerialized inside the ACC region
regardless of its input source.

[CIR][AArch64] Add missing lowerings for vceqz_* Neon builtins (#184893)
Implement the remaining CIR lowerings for the AdvSIMD (Neon)
`vceqz{|q|d|s}_*` intrinsic group (bitwise equal to zero).
The `vceqzd_s64` variant was already supported; this patch completes
the rest of the group [1].
Tests for these intrinsics are moved from:
* test/CodeGen/AArch64/neon-misc.c
to:
* test/CodeGen/AArch64/neon/intrinsics.c
The implementation largely mirrors the existing lowering in
CodeGen/TargetBuiltins/ARM.cpp.
`emitCommonNeonBuiltinExpr` is introduced to support these lowerings.
`getNeonType` is moved without functional changes.

[lldb] Automatic indexing for synthetic children of collections (#174885)
Synthetic providers for collection types use a child name format of
"[N]".
This `ValueObjectSynthetic` to automatically convert child names in this
convention to the index embedded in the subscript string. With this
change, synthetic formatters for collections will only need to implement
`GetIndexOfChildWithName` or `get_child_index` for non-indexed
collection children. Some examples of non-indexed children are
`$$dereference$$` support, or "hidden" children.
The automatic conversion applies to N values that are less than the
number of children reported by the synthetic provider.

Previously only the old barrier name was implemented. Define this
as an indirection around the new name, and move it to common code.
The target implementations are already provided by
__clc_work_group_barrier,
so targets were unnecessarily duplicating these.
This also fixes the default scope, which should be
memory_work_group_scope. Previously this was guessing that
if the flags included global memory, it makes the scope
device which is not the case.

[clang][modules] -Wmodule-import-in-extern-c should not be an error by default (#184530)
Importing a module inside of an `extern "C" {...}` section doesn't have
any effect, i.e. the imported module is not treated as `extern "C"`,
it's built independent of the includer state. The warning is akin to
`-Wconfig-macros`, it's trying to say that the behavior will be
different (and unexpected) when compiling with modules. That doesn't
need to be an error, a warning is enough. As an error, it makes it
difficult to support and test modules in C++ mode while dependencies
still have includes in `extern "C" {...}`.

[SYCL] SYCL host kernel launch support for the sycl_kernel_entry_point attribute. (#152403)
The `sycl_kernel_entry_point` attribute facilitates the generation of an
offload kernel entry point function based on the parameters and body
of the attributed function. This change extends the behavior of that
attribute to support integration with a SYCL runtime library through
an interface that communicates symbol names and kernel arguments
for the generated offload kernel entry point functions.
Consider the following function declared with the
`sycl_kernel_entry_point` attribute with a call to this function
occurring in the implementation of a SYCL kernel invocation function
such as `sycl::handler::single_task()`.
```c++
template<typename KernelName, typename KernelType>
[[clang::sycl_kernel_entry_point(KernelName)]]
void kernel_entry_point(KernelType kernel) {
kernel();
}
```
The body of the above function specifies the parameters and body of the
generated offload kernel entry point. Clearly, a call to the above
function by a SYCL kernel invocation function is not intended to execute
the body as written. Previously, code generation emitted an empty
function body so that calls to the function had no effect other than to
trigger the generation of the offload kernel entry point. The function
body is therefore available to hook for SYCL library support and is now
substituted with a call to a (SYCL library provided) function template
or variable template named `sycl_kernel_launch()` with the kernel
name type passed as the first template argument, the symbol name
of the offload kernel entry point passed as a string literal for the first
function argument, and the function parameters passed as the
remaining explicit function arguments. Given a call like this:
```c++
kernel_entry_point<struct KN>([]{})
```
the body of the instantiated `kernel_entry_point()` specialization would
be substituted as follows with "kernel-symbol-name" substituted for the
generated symbol name and `kernel` forwarded.
```c++
sycl_kernel_launch<KN>("kernel-symbol-name", kernel)
```
Name lookup and overload resolution for the `sycl_kernel_launch()`
function is performed at the point of definition of the
`sycl_kernel_entry_point` attributed function (or the point of
instantiation for an instantiated function template specialization). If
overload resolution fails, the program is ill-formed.
Implementation of the `sycl_kernel_launch()` function might require
additional information provided by the SYCL library. This is facilitated
by removing the previous prohibition against use of the
`sycl_kernel_entry_point` attribute with a non-static member function.
If the `sycl_kernel_entry_point` attributed function is a non-static
member function, then overload resolution for the `sycl_kernel_launch()`
function template may select a non-static member function in which case,
`this` will be implicitly passed as the implicit object argument.
If a `sycl_kernel_entry_point` attributed function is a non-static
member function, use of `this` in a potentially evaluated expression is
prohibited in the definition since `this` is not a kernel argument and
will not be available within the generated offload kernel entry point
function. The attribute cannot be applied to a function with an
explicit object parameter.

[ELF] Add target-specific relocation scanning for RISC-V (#181332)
Implement RISCV::scanSectionImpl, following the pattern established
for x86 (#178846) and AArch64 (#181099). This merges the getRelExpr
and TLS handling for SHF_ALLOC sections into the target-specific
scanner, enabling devirtualization and eliminating abstraction
overhead.
- Inline relocation classification into scanSectionImpl with a switch
on relocation type, replacing the generic rs.scan() path.
- Use processR_PC/processR_PLT_PC for common PC-relative and PLT
relocations.
- Handle TLS IE and GD directly (RISC-V does not optimize GD/LD/IE).
- Replace TLS-optimization-specific expressions for TLSDESC, following
the x86 pattern: R_RELAX_TLS_GD_TO_IE -> R_GOT_PC,
R_RELAX_TLS_GD_TO_LE -> R_TPREL. Update relocateAlloc and relax()
to dispatch on relocation type instead of RelExpr for TLSDESC.
- Simplify getRelExpr to only handle relocations needed by
relocateNonAlloc and preprocessRelocs.
- Remove RISC-V-specific checks from handleTlsRelocation (isRISCV
variable, TLSDESC label special cases).
- Move R_RISCV_VENDOR handling into the relocation type switch. An
undefined vendor symbol now gets the standard undefined symbol error
instead of a vendor-specific diagnostic.

[SandboxVec][DAG] Handle unscheduled successors when user is external (#183861)
Whenever an IR use-def edge gets updated, the DAG gets notified about
the change by having its `notifySetUse()` callback called. The
callback's job is to update the DAG node's `UnscheduledSuccs` counter
which is the number of successor nodes that are yet to be scheduled.
This update makes sense only if both ends of the use-def edge are in the
DAG. Up until now we would still update the counter even if the user was
outside the DAG. This patch fixes this, so from now on we skip updatinge
`UnscheduledSuccs` if the user is outside the DAG.

[libc++][string] Replace ASAN volatile wrapper with memory barrier (#184693)
The previous `_LIBCPP_ASAN_VOLATILE_WRAPPER` approach was used to
prevent
speculative loads of string data before the short/long state was
determined. This patch replaces that mechanism with a more explicit
`__annotate_memory_barrier()` using an empty volatile assembly block.
This PR is inspired by #183457 and by downstream false positive on
`__get_long_size`. It fails same way as `__get_long_pointer` before we
have
`_LIBCPP_ASAN_VOLATILE_WRAPPER`. Barrier approach avoids
expanding `_LIBCPP_ASAN_VOLATILE_WRAPPER` for size_t, and to
in general looks more readable.
I failed to create reasonable reproducer for test, I suspect it requires
precise set of compiler flags, and libc++ site_config which will be hard
to maintain in test.

[mlir] Improve dialect conversion failure diagnostics (#182729)
This PR improves MLIR dialect conversion failure diagnostics when
legalization fails.
Previously, the diagnostic mostly included the operation name (and in
partial conversion, whether it was explicitly marked illegal). This
change keeps that prefix and appends the printed failing operation. This
provides immediate operand/result/type context directly in the same
error line.
### Example
Before:
```
failed to legalize operation 'test.type_consumer' that was explicitly marked illegal
```
After:
```
failed to legalize operation 'test.type_consumer' that was explicitly marked illegal: "test.type_consumer"(%arg0) : (f32) -> ()
```
### Tests
- Updated `mlir/test/Transforms/test-legalizer.mlir` expectations for
the richer emitted diagnostic.

the smallest splat size in the constant. This allow us to use
pli.b for i16 or i32 elements that contain a byte splat.

[DA] Fix the Weak Zero SIV tests when the coeff may be zero (#183736)
In the Weak Zero SIV tests, given two subscripts `{c0,+,a}` and `c1`,
when `c0 == c1`, the tests conclude that a dependency exists from the
former subscript at the first iteration to the latter subscript at every
iteration. However, this conclusion is correct only when `a` is not
zero, which was not being checked.
This patch adds non-zero checks for `a` in the Weak Zero SIV tests.
Fix the test cases added in #183735 .

For wasm, forming minnum/maxnum style ISD nodes is non-profitable,

pmin/pmax instructions that correspond to the fcmp+select semantics, or
relaxed_fmin/relaxed_fmax (for the nnan+nsz case) with even loser
semantics.
As such, return false from isProfitableToCombineMinNumMaxNum(), and also
respect that hook in the SDAGBuilder.

[ORC] Make ElementSet, ContainerElementsMap inner classes. (#184955)
ElementSet and ContainerElementsMap were type aliases inside
WaitingOnGraph.
This commit replaces the aliases with classes deriving from DenseSet and
DenseMap, with convenience operations added for WaitingOnGraph (merge,
remove, remove_if, and visit). These convenience functions are used to
simplify the implementation of various parts of WaitingOnGraph.
Unit tests are added for the convenience operations to improve test
coverage.
In addition to improving readability of the main WaitingOnGraph
operations, this will make it easier to experiment with other underlying
representations for these types (e.g. sorted vectors).

[CodeGen] Use data layout aware constant folder in CGBuilder (#184819)
Use the DataLayout-aware TargetFolder instead of ConstantFolder in
Clang's CGBuilder. The primary impact of this change is that GEP
constant expressions are now emitted in canonical `getelementptr i8`
form. This is in preparation for the migration to ptradd, which requires
this form.
Part of the test updates were performed by Claude Code and reviewed by

[mlir] [linalg] fix failure on specializing matmul with permuted loops (#184294)
This patch fixes generic specialization when the loop dimensions are
permuted in the generic w.r.t. to canonical iterator order of the named
ops by not forwarding the maps of the original generic and instead
recreating them ensuring they always follow the canonical order.
For example, the generic which is to be specialized to a matmul could
have `[parallel, reduction, parallel]` loops, specializing this as is
and just coping the indexing maps like we do now will lead to a
verification error since the dimension will not match the canonical form
the matmul named op expects
e.g. the maps could be:
```
(m, k, n) -> (m,k)
...
```
So we would have to recreate the maps to be:
```
(m,n,k) -> (m,k)
...
```

[lldb] Initial plugin and test for SymbolLocatorSymStore (#183302)
Minimal infrastructure for a the SymbolLocator plugin that fetches debug
info from Microsoft SymStore repositories. More features will follow.
SymbolVendorPECOFF was tailored towards DWARF debug info so far. This
patch adds code to load the PDB path from the executable and not bail
out if DWARF sections are missing, so that in the PDB case we still
call `AddSymbolFileRepresentation()` in the very end of
`CreateInstance()`.
The API test in this patch mocks the directory layout from SymStore, so
it doesn't depend on `SymStore.exe` from the Windows SDK. It runs on all
platforms that link debug info in a PDB file, which is still just
Windows, but it could be cross-platform in principle.

[AMDGPU] Make chain functions receive a stack pointer (#184616)
Currently, chain functions are free to set up a stack pointer if they
need one, and they assume they can start at scratch offset 0. This is
not correct if CWSR and dynamic VGPRs are both enabled, since in that
case we need to reserve an area at offset 0 for the trap handler, but
only when running on a compute queue (which we determine at runtime).
Rather than duplicate in every chain function the code sequence for
determining if/how much scratch space needs to be reserved, this patch
changes the ABI of chain functions so that they receive a stack pointer
from their caller.
Since chain functions can no longer use plain offsets to access their
own stack, we'll also need to allocate a frame pointer more often (and
sometimes also a base pointer). For simplicity, we use the same
registers that `amdgpu_gfx` functions do (s32, s33, s34). This may
change in the future. Chain functions never return to their caller and
thus don't need to preserve the frame or base pointer.
Another consequence is that now we might need to realign the stack in
some cases (since it no longer starts at the infinitely aligned 0).

[mlir][affine] Fix crash in super-vectorize when inner loop bounds depend on outer IV (#184770)
When affine-super-vectorize creates the vectorized version of an inner
loop whose bounds reference the outer loop's induction variable, it was
passing the original scalar bound operands directly to the new vector
AffineForOp. These operands reference block arguments of the scalar
outer loop, which are destroyed when the scalar loop nest is erased,
triggering a use_empty() assertion.
Fix this by replacing the bound operands with their scalar value
replacements (via getScalarValueReplacementsFor) before creating the new
vector loop, ensuring the vector inner loop uses the vector outer loop's
induction variable.

[mlir][bufferization] Fix crash in buffer-hoisting on unreachable blocks (#184094)
`BufferAllocationHoisting::hoist()` iterates over all allocations in a
function and tries to move them to their common dominator block. When an
allocation is in an unreachable basic block (a block that cannot be
reached from the function entry), the LLVM dominator tree has no node
for that block. Two subsequent calls would then crash:
1. `findCommonDominator` calls `findNearestCommonDominator` which calls
the LLVM DomTree equivalent and hits the assertion `NodeA && "A must be
in the tree"`.
2. `findPlacementBlock` calls `dominators.getNode(currentBlock)` on the
unreachable block, which returns null, causing a null dereference on
`->getIDom()`.
Fix by skipping allocations whose parent block is not reachable from the
entry block of the function. Such allocations are in dead code and there
is no need to hoist them.

[mlir][affine] Reject affine.for with step <= 0 in parser and verifier (#184158)
An affine.for loop with step 0 caused a crash in affine-loop-unroll due
to a division-by-zero assertion in getTripCountMapAndOperands:
llvm::divideCeilSigned(loopSpan, step) -- step == 0
The parser already rejected negative steps but allowed zero through.
Fix this by:
- Updating the parser to reject any step <= 0 (not only negative).
- Adding a verifier check in AffineForOp::verifyRegions() so that loops
constructed programmatically with an invalid step are caught before any
analysis pass runs.
- Adding a defensive early-return guard in getTripCountMapAndOperands
for step <= 0, consistent with getTrivialConstantTripCount which already
performs this guard.

[mlir][scf] Fix crash in loopUnrollJamByFactor for zero trip count loops (#184620)
When loopUnrollJamByFactor is called on a loop with a zero trip count
(e.g., lb == ub), the function correctly detects that the unroll factor
exceeds the trip count and adjusts it to match. However, capping the
factor at 0 leads to unsigned underflow when computing the SmallVector
size for `operandMaps(unrollJamFactor - 1)`, resulting in an attempt to
allocate ~2^64 elements and an immediate crash.
Add an early return when the trip count is zero, matching the pattern
already used by loopUnrollFull. A loop that executes zero times needs no
unrolling.

[mlir] Defer `LoopLikeOpInterface` type checks to `RegionBranchOpInterface` (#184116)
`LoopLikeOpInterface`'s verifier hardcodes type equality checks for
init/iter_arg/yield/result edges. This prevents downstream ops with
compatible-but-unequal types from using the pass verifier, since there
is no override mechanism.
`RegionBranchOpInterface` already verifies types along all control-flow
edges and provides an overridable `areTypesCompatible` hook. In
practice,
most loop ops implement both interfaces, making the
`LoopLikeOpInterface`
type checks redundant (the existing code even had a comment
acknowledging
this).
This PR removes the redundant type checks from `LoopLikeOpInterface`
when the op also implements `RegionBranchOpInterface`, letting that
interface handle type compatibility (including any custom
`areTypesCompatible` overrides). For ops that only implement
`LoopLikeOpInterface` (e.g. `affine.parallel`, `tosa.while_loop`), the
strict type equality checks are retained as a fallback. the verifier's
loop-result check to use structured bindings with `llvm::enumerate` and
remove dead variables.

[ORC] Add no-overlap check to WaitingOnGraph::ElementSet::merge. (#184992)
When merging ElementSets and ContainerElementMaps, clients can now
assert that no elements in the merged sets / maps overlap.
Use this to (1) replace a loop in the WaitingOnGraph::Coalescer that was
already checking this condition, and (2) add this check to an existing
merge that should have this property.

[clang][test] Ensure the builtin_vectorelements.c test is actually executed (#184978)
The REQUIRES statement in the builtin_vectorelements.c test case is an
all-or-nothing declaration, hence all of the required conditions would
need to be fulfilled to make this test being executed. Namely, all of
those required targets whould have to be registered, which is a rare
situstion, therefore this test case is rarely ever executed.
This patch changes those REQUIRES statements into %if conditions.
These conditions are needed for those particular targets as their test
sections do include the header files available only when those targets
are registered.

[AArch64][Thumb2] Add missing select FMF in tests
These currently have the "fast" flag on the fcmp, but not the
select. The transform actually needs it (or more specifically the
nsz flag) to be on the select for correctness, but due to an
implementation bug it's currently accepted on the fcmp as well.
I don't believe the intent of any of these tests is to test
specifically the "fast fcmp with non-fast select" situation,
so add the missing flag to the select instructions.

[InstCombine] Canonicalize GEP source element types (#180745)
Canonicalize GEP source element types from `%T` to `[sizeof(%T) x i8]`.
This is intended to flush out any remaining places that rely on GEP
element types, as part of the `ptradd` migration. The impact of this
change is expected to be fairly minimal (we might enable a few more
hoist/sink style folds that depend on equal GEP types).

[CI][libsycl] Add libsycl precommit testing job (#184174)
We want to add some basic precommit CI for `libsycl`, similar to what we
have for `SPIR-V`.
Here it just builds `libsycl` and runs `check-sycl`, but only non-GPU
tests will be run because this job is run on GitHub-hosted runners which
don't have a GPU, so we will never run GPU tests in this CI job.
Postcommit already runs SYCL GPU tests.
We have runtime GPU detection as part of the `check-sycl` lit setup so
everything works fine.
Currently there is only one `check-sycl` test at all and it is a GPU
test, so `check-sycl` is basically a no op, so this is de-facto build
only.

[LV] Support interleaving with FindLast reductions (#184099)
This extends the existing support to work with arbitrary interleave
factors. The main change here is reworking the ExtractLastActive
VPInstruction to take a variable amount of arguments and handling it in
unrollRecipeByUF and VPInstruction::generate.
The select condition for all mask/data values in a find-last recurrence
is the true if the mask for any part is true. Because of this the masks
for inactive parts will be updated to all-false when the parts with
active lanes are updated. This ensures the mask/data for last active
element always corresponds to the greatest part with an active lane.
This means finding the last element in the middle block simply requires
chaining the `extract.last.active` to forward the result from the last
active part through any inactive parts ahead of it.

[ConstantFolding] Consider `tanh*` to always be a noop (#70794)
fixes https://github.com/rust-lang/rust/issues/108965
Most trigonometry functions are already considered, but tanh* was
missing. According to POSIX, these functions may fail on subnormals, so
we choose not to fail, allowing the calls to be eliminated.
https://pubs.opengroup.org/onlinepubs/9699919799/functions/tanh.html
The existing test llvm/test/Transforms/InstSimplify/ConstProp/calls.ll
already eliminated the call since it marked tanh as `nounwind`, which
causes it to be eliminated as well.
I am not sure whether I should add a new test without the `nounwind` or
whether it makes more sense to remove the `nounwind` from the existing
tests.

[mlir][test] Reject TestWithBoundsOp with mismatched attribute width in verifier (#184093)
Add a verifier to `TestWithBoundsOp` that rejects bounds attributes
whose
bit width does not match the result type's storage width (e.g., `10 :
i64`
for an `i8` result). This makes the mismatch invalid IR rather than
silently
accepting it, preventing downstream crashes in consumers such as
`TestReflectBoundsOp::inferResultRanges` that assert on matching widths.
`inferResultRanges` is reverted to its original one-liner; the new
`verify()` method enforces the invariant at IR construction time.
A dedicated test file (`infer-int-range-test-ops-invalid.mlir`) uses
`-verify-diagnostics` to check the emitted error message.

[CUDA/HIP] Do not ignore complete destructors in abstract classes (#184894)
Summary:
The complete destructor destroys virtual base subobjects even for
abstract classes, so target inference must consider vbases when
analyzing destructors.
This was motivated by behavior observed from a bug where a constexpr
function that calls a non-constexpr function. I believe this error is
secondary, but can be fixed by this observation. The issue was the
switch to C++20 allowing allocator destructors to be constexpr began
opting the function into `__host__ __device__` contexts. This function
then called a non-constexpr function through a type-trait interface
which lead to that only having `__host__` which is illegal.
The fix offered here is to check the bases of this function and
correctly derive that it is `__host__` and not `__host__ __device__` as
was previously inferred. This should only affect cases where the *only*
member is an inherited virtual destructor. Previously we found no bases
and thus made no judgement.

more functionality, and uses 95% less disk space, so it seems to be the
direction we want to go.
CUDA support remains, this is not needed urgently.

With his permission while he is away, I am resurrecting @zero9178's very
first MLIR PR #65171 that adds an option to change result in the
operation cloning mechanism. This is very useful as cloning is currently
the only way to change the results of an operation.
> Since Operations cannot change the results after creation, a clone is
necessary to create new results. Doing such an operation generically has
not been possible so far. This PR therefore adds a new option to the
CloneOptions struct allowing adding changing the results of the created
operation.

> The caller is responsible to ensure that this is a valid operation and
setting the IRMapping accordingly afterwards if required.

[C++20][Modules] Do not apply `getAdjustedOffset` to file-internal byte offset. (#184956)
In https://reviews.llvm.org/D137214 and
https://reviews.llvm.org/D136624, offset adjustment logic was added to
account for the non-affecting module map files that are removed. While
the adjustment logic applies to global source location offsets, they do
not apply to file-internal offsets (relative within the file).
In `ASTWriter::WritePragmaDiagnosticMappings`, the adjustment is applied
to `StatePoint.Offset`s in `StateTransitions`. However, these offsets
are file-internal offsets, not global source location offsets. As such,
applying adjustment to these offsets result in incorrect diagnostic
behavior from the module.
Specifically, wrapping a piece of code in `pragma clang diagnostic
push/pop`, inside of a module is not applied correctly. A new test case
`diag-pragma-nonaffecting.cpp` was added to verify the broken behavior
as well as the corrected behavior with this commit.

[MLIR] Fix crash in inliner when return arity mismatches call results (#185037)
The `handleTerminator` implementation in the test dialect's inliner
interface was asserting that the number of `test.return` operands equals
the number of values to replace. This assertion fires when inlining a
callee whose body uses `test.return` with values into a call site that
expects zero results (e.g., a void `llvm.func` calling a function whose
implementation uses `test.return` with operands).
Replace the assertion with a conditional early return so the inliner
gracefully skips replacement instead of crashing.

[mlir][ub] Add `m_Poison()` matcher (#185022)
Add a dedicated matcher for poison values in the UB dialect, similar to
`m_Constant()` for general constants. The matcher uses
`PoisonAttrInterface` for future extensibility.
Replace existing checks against `ub::PoisonAttr` with the new matcher.

[VPlan] Optimize resume values of IVs together with other exit values. (#174239)
Remove updateScalarResumePhis and create extracts for live-outs early in
addInitialSkeleton. Instead of extracting the from the header phi
recipes for the resume values (which is incorrect), extract the last
lane of the backedege value.
Then update optimizeInductionExitUsers to optimize both the scalar
resume values for IVs and IV exit values together.
This removes the need to pass state between transforms and addresses a
TODO.

[lldb][windows] fix VT sequences overriding (lldb) prompt (#183366)
This patch fixes the `(lldb)` prompt being overwriten by the cursor
position movements the ConPTY emits.
To be a complete solution we should also add a resize hook for the
console's window.
I also think that we should look into injecting conpty VT sequences
before printing the `(lldb)` prompt.
For instance, if we break on a breakpoint and the pty added a "hide
cursor" VT sequence, we should emit a `show cursor` sequence before
printing `(lldb)`. This should be done outside of this PR however.

[mlir] Fix assertion crash in test-symbol-uses with nested modules (#185069)
The `SymbolUsesPass` walked all nested `SymbolOpInterface` ops in a
module, including those belonging to nested symbol tables (e.g., nested
modules). When an external `func.func` inside a nested module had no
uses in the outer module's body region, it was incorrectly added to
`deadFunctions` for erasure. Since the outer module's `SymbolTable` does
not contain the inner module's symbols, the subsequent
`table.lookup(name)` assertion would fail with:
Assertion `table.lookup(name) && "expected no unknown operations"`
failed.
Fix by only tracking functions that are direct children of the enclosing
module, skipping functions owned by nested symbol tables.

[Clang][ExprConst] Handle APValue::LValue in BitCast (#184865)
Instead of marking the branch unreachable, emit an unsupported type
diagnostic and return false when encountering `APValue::LValue` in
`APValueToBufferConverter`.
A good example of this is:
```
long fn() {
return __builtin_bit_cast(long, (long)&fn);
}
```
Although `&fn` itself is a pointer type, the cast `(long)` converts it
to an integer type, which passes `checkBitCastConstexprEligibilityType`.
Thus, eventually, we see it in Converter, which does not expect an
LValue.

[LLDB] Allow one-line summaries in the presence of synthetic child providers (#184926)
This is driven by the Swift language. In Swift many data types such as
Int, and String are structs, and LLDB provides summary formatters and
synthetic child providers for them. For String, for example, a summary
formatter pulls out the string data from the implementation, while a
synthetic child provider hides the implementation details from users, so
strings don't expand their children.

Array new with a runtime bound requires an "array filler" to initialize

constant. Make sure SemaInit doesn't confuse the two cases.

[CIR] Fix array constant initialization with trailing zeros (#184933)
If an array is explicitly initialized with more than eight non-zero
values followed by a number of explicit zero initializers, CIR generates
a constant record initializer with a constant array that is declared as
the size of the non-zero initializers but with the explicit zero
initializers included in the array initialization attribute. This
resulted in an error when we tried to lower that attribute to LLVM IR.
This patch fixes that problem and adds a verifier to ConstantArrayAttr
to check for that condition.

[Clang] Fix invalid sret addrspacecast for placement new on HIP (#183639)
When a HIP kernel uses placement new with a function returning an
aggregate via sret (e.g. `new (out) T(make_t())`), and the placement
destination is in global memory (addrspace 1), the sret pointer was
addrspacecast'd to addrspace 5 (private), producing an invalid pointer
that faults at runtime.
Instead of casting the caller's pointer directly, materialise a
temporary alloca in the callee's expected address space, pass that as
the sret argument, and copy the result back to the original destination
after the call.

[clang][diagnostics] Stable IDs for Clang diagnostics (#168153)
Part of the implementation of [[RFC] Emitting Auditable SARIF Logs from
Clang](https://discourse.llvm.org/t/rfc-emitting-auditable-sarif-logs-from-clang/88624)
SARIF diagnostics require that each rule have a stable `id` property to
identify that rule across runs, even when the compiler or analysis tool
has changed. We were previously setting the `id` property to the numeric
value of the enum value for that diagnostic within the Clang
implementation; this value changes whenever an unrelated diagnostic is
inserted or removed earlier in the list.
This change sets the `id` property to the _text_ of that same enum
value. This value would only change if someone renames the enum value
for that diagnostic, which should happen much less frequently than
renumbering.
For now, we will just assume that renaming happens infrequently enough
that existing consumers of SARIF will not notice. In the future, we
could take advantage of SARIF's support for `deprecatedIds`, which let a
rule specify the IDs by which it was previously known. This would let us
rename, split, or combine diagnostics while still being able to
correlate the new diagnostic IDs with older SARIF logs and/or
suppressions.
Nothing in this change affects how warnings are configured on the
command line or in `#pragma clang diagnostic`. Those still use warning
groups, not the stable IDs.
### Potential discussion topics
>From @AaronBallman on the RFC:
>We believe some open questions remain (things like whether a unique ID
is on the per-diagnostic level or on the diagnostic group level, whether
the ID is explicitly spelled in the .td file or implicitly generated,
whether we document the IDs, etc), but we think those questions are best
decided in PR discussions with interested parties rather than an RFC.
As a starting point, this PR proposes the following answers to those
open questions:
- _whether a unique ID is on the per-diagnostic level or on the
diagnostic group level_ - per-diagnostic level. For my justification,
see [this portion of the RFC
discussion](https://discourse.llvm.org/t/rfc-emitting-auditable-sarif-logs-from-clang/88624/11?u=dbartol.).
- _whether the ID is explicitly spelled in the .td file or implicitly
generated_ - Implicitly generated, but I'd be happy to have a way to
explicitly specify it. I just think that the in-code identifier is a
reasonable default, and manually reviewing the IDs of thousands of
existing diagnostics would add little benefit.
- _whether we document the IDs_ - For now, the IDs are only exposed to
the user (and other tools) in the SARIF file, so I don't think we need
to document these. We could certainly add this information to the output
of `diagtool` in the future if users find it relevant.

[clang][CodeGen] Fix size calculation in vbptr split memory region in EmitNullBaseClassInitialization (#184558)
When splitting memory stores around multiple virtual base pointers
(vbptrs)
in the Microsoft ABI, the calculation for the size of the memory region
after
each vbptr was incorrect.
The bug/old calculation: SplitAfterSize = LastStoreSize -
SplitAfterOffset
This subtracts an absolute offset from a relative size, causing
incorrect (too small) sizes after the second vbptr.
The correct size should be:
SplitAfterSize = (LastStoreOffset + LastStoreSize) - SplitAfterOffset
Since all store regions extend to the end of the non-virtual portion
(NVSize),
this patch uses the simplified form:
SplitAfterSize = NVSize - SplitAfterOffset
The bug causes the assertion failure: "negative store size!"

When we call `getLoc()` with an invalid `SourceLocation` and

down one case where this was happening (generating an argument in a
vtable thunk) and fixed that to provide a location. I also am updating
the `getLoc()` implementation so that it will use an unknown location in
release builds rather than crashing because the location isn't critical
for correct compilation.

[flang,acc] Support -ffp-maxmin-behavior option in lowering. (#184730)
This patch adds `flang -fc1` option `-ffp-maxmin-behavior` and
propagates it throughout Flang, so that semantics context,
lowering and the pass pipeline builder can use it.
MAX/MIN intrinsic and OpenACC max/min reduction lowering
are now controlled by the option.
I kept the `Legacy` mode, which is the default and matches the current
behavior. I am going to test and merge a follow-up patch that
replaces `Legacy` with `Portable`.

[ASan][Windows] Fixing Windows shadow memory address for arm64 (#184902)
This is a prerequisite for full ARM64 Windows ASan support. The runtime
interception changes needed to make ASan functional end-to-end on ARM64
Windows will be opened separately.
Motivated by https://github.com/microsoft/STL/pull/6095 (more
specifically [this reference to
clang-cl](https://github.com/microsoft/STL/pull/6095#:~:text=Not%20enabling%20GH_002030_asan_annotate_string%20and%20GH_002030_asan_annotate_vector%20yet%20due%20to%20Clang%20issues.))
The latest MSVC toolset includes ARM64 AddressSanitizer support. This
change adds AArch64 to the Windows 64-bit shadow mapping condition when
compiling with `-fsanitize=address` with `clang-cl`. Without this,
consumers on Windows who target ARM64 with `clang-cl -fsanitize=address`
and then link with `link.exe` will see this at runtime:
```text
ERROR: AddressSanitizer: access-violation on unknown address
...
```
since the shadow memory offset is not properly assigned. Windows ARM64
uses the same dynamic shadow allocation strategy as x64 via
`__asan_shadow_memory_dynamic_address`.

it incorrectly assumes `std::uniform_int_distribution` returns the same
result with different C++ stdlib vendors.

[mlir][ODS] Fix notorious double-space bug in op printers (#184253)
When an op's assembly format prints an attribute via
`printStrippedAttrOrType`, two independent space-emission mechanisms
would fire: the op format generator emits a space before each argument,
and the attribute's generated `print` method also emits a leading space
(`shouldEmitSpace` initialized to true). This caused double spaces like
`gpu.shuffle xor`.
The usual workaround for this was to add double backticks to consume the
leading space.
Fixed by removing the leading space from generated attr/type `print()`
methods and compensating in the print dispatcher by conditionally adding
a space between the mnemonic and `print` call when the format starts
with a name or keyword rather than punctuation.
Also remove some workarounds for the double-spacing in op formats and
fix tests that now don't have leading spaces.

[HLSL][DirectX] Implement HLSL `mul` function and DXIL lowering of `llvm.matrix.multiply` (#184882)
Fixes #99138
- Defines a `__builtin_hlsl_mul` clang builtin in `Builtins.td`.
- Links the `__builtin_hlsl_mul` clang builtin with
`hlsl_alias_intrinsics.h` under the name `mul` for matrix cases
- Implement scalar and vector elementwise multiplication cases of the
`mul` function in `hlsl_intrinsics.h` and `hlsl_intrinsic_helpers.h`
- Adds sema for `__builtin_hlsl_mul` to `CheckBuiltinFunctionCall` in
`SemaHLSL.cpp`
- Adds codegen for `__builtin_hlsl_mul` to `EmitHLSLBuiltinExpr` in
`CGHLSLBuiltins.cpp`
- Vector-vector cases lower to `dot` (except double vectors, which
expands to scalar multiply-adds).
- Matrix-matrix, matrix-vector, and vector-matrix multiplication lower
to the `llvm.matrix.multiply` intrinsic
- Adds codegen tests to `clang/test/CodeGenHLSL/builtins/mul.hlsl`
- Adds sema tests to `clang/test/SemaHLSL/BuiltIns/mul-errors.hlsl`
- Implements lowering of the `llvm.matrix.multiply` intrinsic to DXIL in
`DXILIntrinsicExpansion.cpp`
Note: Currently the SPIRV backend does not support row-major matrix
memory layouts when lowering matrix multiply, and just assumes
column-major layout. Therefore this PR also makes the DirectX backend
only assume column-major layout. Implementing support for row-major
order shall be done in a separate PR. (Tracked by

The existing code was factoring out the instruction deletion and the
setting of the collected instruction variables. But the special handling
for DEPCTR and the in-loop deletion of `S_WAITCNT_lds_direct` was just
complicating the logic.

[lldb] Use range-based for loops over plugins (#184837)
This PR replaces the Get*CallbackAtIndex pattern in the PluginManager
with returning a snapshot of callbacks that the caller can iterate over
using a range-based for loop. This is a continuation of #184452 which
added thread safety by using snapshots. However, that introduced a bunch
of unnecessary copies which are largely eliminated again by getting the
snapshot once when gather all the callbacks, rather than doing that on
each iteration when querying a plugin for a given index. It also
eliminates the possibility of the snapshot changing underneath you when
iterating over the plugins.
This change was largely mechanical and I used Claude to do the menial
work of updating the signatures and call sites.

[clang][Dependency Scanning] Fix the In-Memory Buffer Used for By-Name Scanning (#183396)
This PR fixes two issues of the in-memory buffer we use for the input
file when a dependency scanner performs by-name queries.
First, it renames the buffer. The temporary file was named
`ScanningByName-%%%%%%%%.input`, which leads to weird diagnostics such
as
```
ScanningByName-2d42a1e9.input:1:1: fatal error: could not build module 'X'
```
This PR changes the name of the file buffer, so we get diagnostics such
as
```
module-include.input:1:1: fatal error: could not build module 'X'
```
which is more indicative.
Additionally, this PR fixes a bug where the source location may overflow
the temporary buffer by creating a 64k empty string which the temporary
buffer occupies. When the source location overflows, the diagnostics
could point to some random file that comes after the fake file and is
incorrect.
Currently, the maximum number of unique names from Apple's SDKs is
around 3000. A 64k buffer per dependency scanning worker gives us around
20x capacity per worker (which scans fewer names than 3000 when the
scanning is done in parallel). A fatal error is added to catch
overflows.

[SelectionDAG] Optimize 32-bit udiv with 33-bit magic constants on 64-bit targets (#181288)
This PR optimizes 32-bit unsigned division by constants when the magic
constant is 33 bits (IsAdd=true case in UnsignedDivisionByConstantInfo)
on 64-bit targets.
## Overview
Compiler optimization for constant division of `uint32_t` variables
(such as `x / 7`) is based on the method
proposed by Granlund and Montgomery in 1994 (hereafter referred to as
the GM method).
However, the GM method for the IsAdd=true case was optimized for 32-bit
CPUs, not 64-bit CPUs.
This patch provides optimizations specifically for 64-bit CPUs (such as
x86_64 and Apple M-series).
A simple benchmark demonstrates over 60% speedup on both Intel Xeon and
Apple M4 processors.
## The GM Method
The GM method for `x / 7` can be expressed in C code as follows,
where the constants `c` and `a` are magic numbers determined by the
divisor:
```cpp
uint32_t udiv_original(uint32_t x) {
uint64_t v = x * c;
v >>= 32;
uint32_t t = uint32_t(x) - uint32_t(v);
t >>= 1;
t += uint32_t(v);
t >>= a - 33;
return t;
}
```
For example, division by 7 on x86_64 generates 7 instructions:
```asm
movl %edi, %eax
imulq $613566757, %rax, %rax
shrq $32, %rax
subl %eax, %edi
shrl %edi
addl %edi, %eax
shrl $2, %eax
```
## Proposed Solution
This patch generates the following optimized code:
```cpp
uint32_t udiv_optimized(uint32_t x) {
uint128_t v = uint128_t(x) * ((c + 0x100000000) << (64 - a));
return uint32_t(v >> 64);
}
```
Since a 64-bit right shift of a 128-bit variable extracts the upper 64
bits,
this code eliminates the need for shifts after multiplication.
The implementation pre-shifts the 33-bit magic constant `c = 2^32 +
Magic` left by `(64-a)` bits
and uses the high 64 bits of a 64 x 64 -> 128 bit multiplication
directly.
This eliminates the add/sub/shift sequence.
After optimization, division by 7 becomes 4 instructions (or 3 with
BMI2):
```asm
# Standard (4 instructions)
movl %edi, %eax
movabsq $2635249153617166336, %rcx
mulq %rcx
movq %rdx, %rax
# With BMI2 (3 instructions)
movl %edi, %edx
movabsq $2635249153617166336, %rax
mulxq %rax, %rax, %rax
```

The default move constructor wasn't nulling out the callbacks. Combined
with the fact that llvm::sys::DynamicLibrary has no explicit move
constructor and hence library.isValid() still returned true after having
moved-from, we would end up calling plugin_term_callback() when
destroying the moved-from PluginInfo, calling it prematurely.

PR https://github.com/llvm/llvm-project/pull/182083 forgot to switch
over to use the newly added `DebugMapFilter` when parsing
`--allow/--disallow` YAML input. It was still using
`ObjectFileList`/`ObjectFileEntry`, which was added initially in the
same PR and was later intended to be replaced by `DebugMapFilter`.
This patch switches over to use `DebugMapFilter`, adds necessary YAML
traits, and removes `ObjectFileList`/`ObjectFileEntry`.

Before the patch moved from object was in consistent state.
For some types it resets contents and switch to T_Null, for others
it preserves type and value.
So make sure to set T_Null for all.
When we set T_Null we need to destroy the value.
It's important for particular types, like std::string. With
Asan it must unpoison SSO buffer.

[clang-doc][NFC] Introduce OwnedPtr abstraction (#184869)
Eventually, we want clang-doc to support arena allocation, but the
widespread use of owning pointers in the data types prevents this.
Rather than have wide scale refactoring, we can introduce a type alias
that can be swapped out atomically to switch from smart pointers to raw
pointers. This is the first of several refactorings that are intended to
make the transition simpler.

[CIR] Fix operator-precedence bugs in assert conditions (#185119)
Due to && binding tighter than ||, asserts of the form
assert(A || B && "msg") always pass when A is true. Add
parentheses so the string message is properly attached:
assert((A || B) && "msg").

[ubsan_minimal] Build on Solaris (#184976)
Two tests currently `FAIL` on Solaris/amd64 and Solaris/sparcv9:
```
SafeStack-Standalone-i386 :: overflow.c
SafeStack-Standalone-x86_64 :: overflow.c
```
This happens because `libclang_rt.ubsan_minimal.a` isn't built on
Solaris although it's required with `-fsanitize-minimal-runtime`.
This patch fixes this.
Tested on `amd64-pc-solaris2.11` and `sparcv9-sun-solaris2.11`.

There is no reason to double-wrap iterators, since we can already
achieve anything we want within `__bounded_iter`itself.
This is technically ABI breaking, but people using bounded iterators
shouldn't require ABI stability currently.

[lldb][PlatformDarwin][test] Add unit-test for LocateExecutableScriptingResourcesFromDSYM (#185057)
Depends on:
* https://github.com/llvm/llvm-project/pull/185056
Adds test unit-test for
`PlatformDarwin::LocateExecutableScriptingResourcesFromDSYM`. I had to
mock the `ScriptInterpreter` because the function internally uses the
`ScriptInterpreterPython` to check for reserved words in file names. But
linking the `ScriptInterpreterPython` was quite the undertaking, which I
think we could pull off, but required more churn that I had hoped.
Mocking it seemed pretty low-cost so I resorted to doing that instead.
Test-cases aren't very elaborate yet. It just has a basic assertion that
we locate the Python file within the dSYM. Mostly I set up
infrastructure for future test-cases.

[Reland][llubi] Add support for load/store/lifetime markers (#185196)
This patch relands https://github.com/llvm/llvm-project/pull/182532. The
original version causes test failures related undef bits since it
incorrectly assumes `std::uniform_int_distribution` yields the same
results across different stdlib vendors. This patch simply uses low bits
to avoid the issue. I am not sure whether it still generates uniformly
distributed random numbers. But abseil also uses this trick:
https://github.com/abseil/abseil-cpp/blob/e72b94a2f257ba069ec0b99e557e9f1f6b9c1a3e/absl/random/uniform_int_distribution.h#L203-L206
I have confirmed all tests passed with libstdc++ and libc++.
Original PR description:
Bytes are adjusted to respect the incoming byte type proposed in
https://discourse.llvm.org/t/rfc-add-a-new-byte-type-to-llvm-ir/89522.
Note that the current implementation of constant folding doesn't handle
bitcasts with weird types like `<8 x i3> to <3 x i8>`:
https://github.com/llvm/llvm-project/blob/49de34459c99b33c27aae4596ed5e67ce3d89eae/llvm/lib/Analysis/ConstantFolding.cpp#L223-L232
So I take the result from Alive2 as reference:

build: add `LINKER:` modifier to `/DELAYLOAD:` options (#185086)
When building with the GNU driver, we would pass in `/DELAYLOAD:...`
without indicating that this is a linker flag. `clang` does not
implictly forward non-consumed options to the linker like `cl` does, and
this would cause the build to fail.

[LLDB] Move Itanium language runtime to C++ language runtime (#169225)
In order to support the Microsoft ABI alongside the Itanium one in the
same process from different DLLs, this moves the Itanium ABI runtime
plugin to the C++ language runtime (see
https://github.com/llvm/llvm-project/pull/168941#discussion_r2547684264).
Before this PR, the C++ language runtime wasn't a plugin. Instead, its
functionality was provided by the Itanium ABI plugin.
All Itanium specific methods are moved to a new class
`ItaniumABIRuntime`. This includes resolving the dynamic type, setting
exception filters, and getting the exception object.
The other methods were added to `CPPLanguageRuntime`.
`language cplusplus demangle` moved to `CommandObjectCPlusPlus`.
The Clang REPL depended on the C++ runtime. Now that it's a plugin, this
failed the layering check. Since the REPL doesn't use the C++ runtime, I
removed the dependency.

[libclc] Add custom CMake language handling for OpenCL files (#185243)
Summary:
The current handling of `libclc` is to use custom clang jobs to compile
source files. This is the way we used to compile GPU libraries, but we
have largely moved away from this. The eventual goal is to simple be
able to use `clang` like a normal project. One barrier to this is the
lack of language support for OpenCL in CMake.
This PR uses CMake's custom language support to define a minimal OpenCL
language, largely just a wrapper around `clang -x cl`. This does
nothing, just enables the support. Future PRs will need to untangle the
mess of dependencies.
The 'link+opt' steps that we now do should be able to simply be done as
a custom `llvm-link` and `opt` job on the library, which isn't ideal but
it still better than the current state.

`sockaddr_un` there from `<sys/socket.h>`. See
https://man7.org/linux/man-pages/man0/sys_un.h.0p.html
Add proxy headers for the `<sys/socket.h>` macro (like `AF_UNIX`) and
for the `struct sockaddr_un` so that the tests can be more hermetic and
avoid system header inclusion.

libclc: Add uintptr_t overloads of atomic_fetch_add and sub (#185263)
This is a special case because the pointee type is unsigned, but the
input value is signed. Directly use the opencl builtins, because these
work correctly without any ugly casting required, and it's not worth
putting a wrapper in clc.

[AArch64] Ensure FPR128 callee-save stack offsets are aligned (#184314)
This was benign for Linux targets (as when dividing by the scale the
offset would be correctly truncated), so only resulted in failures with
`-DLLVM_ENABLE_ASSERTIONS=On`. On Windows, this was a miscompile as the
lack of alignment would result in the FPR128 callee-save getting
assigned to the same offset as the previous GPR.

Reapply "[VPlan] Remove manual region removal when simplifying for VF and UF. (#181252)"
This reverts commit d7e037c8383e66e5c07897f144f6d8ef47258682.
Recommit with a small fix to properly handle ordered reductions when
connecting the epilogue.
Original message:
Replace manual region dissolution code in
simplifyBranchConditionForVFAndUF with using general
removeBranchOnConst. simplifyBranchConditionForVFAndUF now just creates
a (BranchOnCond true) or updates BranchOnTwoConds.
The loop then gets automatically removed by running removeBranchOnConst.
This removes a bunch of special logic to handle header phi replacements
and CFG updates. With the new code, there's no restriction on what kind
of header phi recipes the loop contains.
Note that VPEVLBasedIVRecipe needs to be marked as readnone. This is
technically unrelated, but I could not find an independent test that
would be impacted.
The code to deal with epilogue resume values now needs updating, because
we may simplify a reduction directly to the start value.

[MLIR][Presburger] Fix simplify() of IntegerRelation (#181469)
In `simplify()`, we currently skip all columns from 0 to `firstVar` (the
column of the pivot) when we eliminate inequalities. This is invalid,
because unlike equalities, it is not guaranteed that these columns
contain only zeroes, and a scale by `rowMultiplier` cannot be ignored.
We must not skip any columns for inequalities.

If we're just concatenating subvectors together to perform a saturated
truncate, see if we can perform PACK on the subvectors directly instead
- 256-bit PACK will require a post-shuffle, but this will typically fold
away in later shuffle combining and its probably better than changing
vector widths with concats.

only
really works for core types in the `ir` submodule.
* `DefaultingPyMlir*` helpers also produce qualified types, e.g.
`_mlir.ir.Location` instead of bare `Location`.
* `ir.*.__enter__` now returns a concrete type instead of `object`, e.g.
`ir.Context.__enter__` returns `Context`.
* `loc_tracebacks` uses `Generator` as the return type, since this is
what
`contextmanager` expects in typeshed.
* Changed static methods on subclasses of `DenseElementsAttribute` to
return
that concrete subclass, instead of `DenseElementsAttribute`.

[mlir][LLVM] Disallow opaque struct types as function arguments (#185200)
Function types are only allowed to take first-class values as arguments.
The LLVM dialect implemented this correctly so far except for allowing
opaque struct types. When translated to LLVM proper, invalid IR would be
created with confusing assertion errors.
This PR matches LLVM by disallowing opaque struct types as arguments,
allowing users to catch this kind of mistake early while still in the
MLIR world.
The corresponding LLVM logic is here:

[LLVMABI] Introduce the QualTypeMapper (#174634)
This PR introduces the `QualTypeMapper` class, which bridges Clang's
type system with the LLVM ABI type system introduced in
https://github.com/llvm/llvm-project/pull/158329.
The `QualTypeMapper` translates Clang `QualType` instances into their
corresponding LLVM ABI type representations, preserving all ABI-relevant
information while abstracting away frontend-specific details.
The mapper queries the `ASTContext` for layout information computed by
the frontend and uses the `TypeBuilder` API(from the above merged PR) to
construct the corresponding ABI types. This separation ensures that ABI
logic remains independent of frontend AST details while still having
access to all necessary type information.
This is a prerequisite for implementing target-specific ABI lowering, as
demonstrated in https://github.com/llvm/llvm-project/pull/140112

[CI] Try lowering max parallel link jobs on Windows (#185255)
It looks like #177477 might be caused by OOMs due to running too many
link jobs at the same time in rare circumstances. It doesn't reproduce
often enough for me to be able to easily check the event logs to confirm
the OOM killer was involved (I did try 192 runs), but it doesn't hurt to
try. This could slightly decrease performance, but given these are
vCPUs, even if we need to run only link jobs, we should take only a
10-20% performance hit for the link phase, which is generally not a
large portion of the build.

[MLIR][NVVM] Add LLVMIR lowering for nvvm.subf (#184968)
This change adds direct LLVMIR lowering to the `nvvm.subf` operation
added in #179162 to prevent translation failures when canonicalization
is not run. Also adds `mlir-translate` tests for `nvvm.subf`.

up with custom plumbing in both cases, so I am now removing this
effectively dead code.

[X86] Reduce -ffixed-r compile-time overhead (#184606)
PR #180242 added reserve-r support across the driver and backend, but it
also introduced avoidable compile-time work in hot paths.
In Clang, delay +egpr detection until -ffixed-r16 through -ffixed-r31
are actually queried instead of computing it for every x86_64
invocation.
In LLVM, store X86Subtarget::ReservedRReg in a fixed-size std::bitset
and update X86RegisterInfo::getReservedRegs() to iterate only over the
reserve-r register ranges instead of scanning every target register.
These changes keep reserve-r behavior unchanged while trimming the extra
compile-time overhead introduced by the PR.

This adds a singular Builtin dialect version for use with bytecode
serialization. This version is not currently print unless set and not 0
(not planned a bump until next LLVM version). Created a unit test as
this was easiest way to track.
Additionally add emitWarning virtual method to DialectBytecodeReader,
mirroring emitError.
Tested on old mlir-opt reader, and could read, so should be non-breaking
change.

Sgpr spill pseudos didn't enforce alignment constraints.

[Flang] Fix crash in structure constructor lowering for PDT (#183543)
Fixes - [#181278](https://github.com/llvm/llvm-project/issues/181278)
This patch fixes a crash in Flang when parsing array constructors like:
`[ty0(2)(4)]`
The current implementation parses this as a type constructor ty0(2),
followed by what appears to be another call (4), instead of rejecting it
as invalid syntax. The lowering of` StructureConstructor` attempts to
retrieve the parent derived type using `sym->owner().derivedTypeSpec()`,
which return `nullptr` for PDT cases and lead to a crash.
In` flang/lib/Lower/ConvertConstant.cpp`, a safeguard is being added
which ensures that we fall back to the constructor’s derived type
specification when the parent type cannot be obtained, preventing the
null dereference and eliminating the crash. This change addresses only
the immediate crash, proper diagnostic handling for this invalid syntax
is still pending and remains as TODO.

[flang] Fix segfault in CSHIFT/EOSHIFT with dynamically optional DIM (#184431)
When `DIM` is passed as an optional dummy argument and is absent at
runtime, the HLFIR lowering for the `CSHIFT` and `EOSHIFT` intrinsics
treated it as unconditionally present. This resulted in an unconditional
load of the `DIM` reference, causing a null pointer dereference and a
runtime segmentation fault when absent.
The underlying issue was that the `dim` argument for `cshift` and
`eoshift` was not marked with `handleDynamicOptional` during intrinsic
argument lowering setup. As a result, the `isPresent` state was never
populated, and the lowering implementation incorrectly fell through to
an unconditional scalar load.
This patch resolves the issue by:
1. Updating the `dim` entries for `cshift` and `eoshift` in
`IntrinsicCall.cpp` to use `handleDynamicOptional`. This enables
`getOperandVector()` to appropriately emit a guarded load (via
`loadOptionalValue()`) that safely returns a 0 placeholder when `DIM` is
absent.
2. Updating the HLFIR lowering implementations (`HlfirCShiftLowering`
and `HlfirEOShiftLowering`) to use the loaded scalar. It now employs an
`arith.select` to substitute the 0 placeholder with the
standard-mandated default of 1 when `isPresent` is false, matching the
Fortran requirements (§16.9.68 and §16.9.77) without generating
redundant `fir.if` or `fir.load` operations. Explicit `DIM=0` calls
still correctly forward the 0 value to flang-rt to trigger the
appropriate runtime bounds check error.

[libclc] Use custom CMake handling to overhaul libclc compilation (#185247)
Summary:
This PR uses https://github.com/llvm/llvm-project/pull/185243 to
overhaul compilation of libclc. This brings libclc to the same kind of
compilation flow that the other GPU libraries use (compiler-rt, libc,
libc++, openmp, flang-rt).
The main brunt of this change is simply changing the SOURCES files to
CMake variables and altering the compilation. Now that these are
standard CMake libraries we do not need to bother redefining custom
library handling and targets.
This builds as a static library, which we then consume with `llvm-link`
which converts it into a single `.bc` bitcode file similarly to before.
The final result is then optimized all together.
Hopefully this doesn't break anything.

[X86] Fix wrong RIP-relative relocations for AVX10.2 saturation conversions (#185254)
AVX10.2 saturation conversion instructions (VCVT{T}{BF16,PH,PS}2I{U}BS)
incorrectly inherited from AVX512{PS,XD,PD}Ii8Base, which sets
ImmT=Imm8. This caused X86MCCodeEmitter to account for a nonexistent
trailing immediate byte when computing RIP-relative displacement fixups,
producing an addend of -5 instead of the correct -4.
Replace AVX512PSIi8Base/AVX512XDIi8Base/AVX512PDIi8Base with just the
needed prefix classes (PS is default, XD, PD), dropping the bogus
ImmT=Imm8. Preserve the original ExeDomain values (SSEPackedSingle,
SSEPackedDouble, SSEPackedInt; verified with `llvm-tblgen
--print-records ./llvm/lib/Target/X86/X86.td -I./llvm/include/

[X86] TableGen-erate SDNode descriptions (#168421)
This allows SDNodes to be validated against their expected type profiles
and reduces the number of changes required to add a new node.
The first commit contains the main change. There are few nodes that
don't have SDNode records in `*.td` files (see the enum in
`X86SelectionDAGInfo.h`) and several nodes fail verification (see
`X86SelectionDAGInfo::verifyTargetNode`).
The second commit fixes a few bugs in the generic SelectionDAG code that
were detected by the verification functionality.
The third comment moves comments from `X86ISelLowering.h` to `*.td`
files. This is done as separate commit to hopefully simplify the review.
I allowed myself to rearrange some node definitions because they had
block comments in `X86ISelLowering.h`.
Part of #119709.

[SPIRV] In G_SELECT selection path: replace `removeFromParent` with `eraseFromParent` and return early (#184807)
When selecting an `ASSIGN_TYPE` of a `G_SELECT`, both instructions were
removed but not erased.
The code followed on a code path where the replaced G_SELECT would be
added to a remove set if it was dead. But the select is not in the
function anymore since it is already removed!
Selecting a `selectSelect` always returns `true`. So the
assertions/prints below would have never been triggered.
This patch simplifies this code path to avoid falling through the
asserts and paths where `selectSelect` could have failed (which
trivially doesn't happen).
Guarded `selectSelect` return with an assert in case it changes.

Use `getElementAsAPInt(`) to read array elements and emit via
`addIntAsBlock()` which handles target endianness correctly, instead of
`getRawDataValues()` which exposes host endianness. This fixes test
failures on big-endian hosts cross-compiling for little-endian targets.
Reland of #182442 with endianness fix.

[PPC64][Linux] Watchpoint configuration for PPC64 (#185192)
On PPC64, SIGTRAP is delivered before the triggering instruction
completes. The previous implementation wrongly assumed that the
instruction gets executed and due to that qHostInfo has the wrong info,
causing the SingleStep being avoided on Linux for PPC64, and the
execution being stuck at the store instruction.
This patch corrects this, making watchpoint work.

clang/AMDGPU: Fix workgroup size builtins for nonuniform work group sizes (#185098)
These were assuming uniform work group sizes. Emit the v4 and v5
sequences to take the remainder group for the nonuniform case.
Currently the device libs uses this builtin on the legacy ABI path with
the same sequence to calculate the remainder, and fully implements the
v5 path. If you perform a franken-build of the library with the updated
builtin, the result is worse. The duplicate sequence does not fully fold out.
However, it does not appear to be wrong. The relevant conformance tests still

`buildTernaryFn` for `TernaryFn::select` called `llvm_unreachable` when

`index` type).
Instead delegate this checking to the IR verifier: we don't need to
duplicate the checks from the verifier in an assertion here.

[InstCombine] Handle fixed-width results in get_active_lane_mask fold (#185317)
The optimization introduced in #183329 incorrectly assumed that any
extraction from a scalable active lane mask used a scalable index. When
the result of a `llvm.vector.extract` is a fixed-width vector, the index
should not be multiplied by vscale.
This PR adds a check to ensure the index is only scaled by VScaleMin
when the return type of the extraction is a scalable vector, not
fixed-width.

When using `--gpu-to-llvm` with `use-bare-pointers-for-kernels=true` and
a `gpu.launch_func` whose kernel has an `UnrankedMemRefType` argument,
`LLVMTypeConverter::promoteOperands` would hit an `llvm_unreachable`
because unranked memrefs are not supported with the bare-pointer calling
convention.
Fix this by checking for unranked memref kernel arguments before calling
`promoteOperands` and returning a proper conversion failure with a
diagnostic instead of crashing.

[LLVM][AArch64] Allow vector converts to run in streaming mode with … (#177375)
…FPRCVT
Vector Saturated converts fp->int and converts int->fp are now allowed
to run in streaming mode when FEAT_FPRCVT feature is available.
Therefore the patch replaces HasNEONandIsSME2p2StreamingSafe by
HasNEONandIsFPRCVTStreamingSafe following the latest update in [1] for
the Vector CVT instructions.
It also allows the ISD Node FP_TO_SINT_SAT to do custom lowering instead
of expand when it is a fixed lengh data type, because it can use the
Vector CVT instructions. I believe this is correct because there is
always a compatible CVT instruction for the SME core.
Because now the compiler allows the fixed length CVT to run in streaming
mode, I needed to fix the function LowerVectorFP_TO_INT_SAT, the FRINT
instruction were creating a ilegal size for CVT instructions that was
not able to lower to a CVT instruction.

[MLIR][LLVMIR] Fix inline byval alloca hoisting out of allocation scope (#185399)
This PR fixes a bug of the LLVM dialect's function inlining, which
materializes allocas for byval arguments and moves them to the entry
block for optimization. This optimization should not cross allocation
scopes, as it leads to data races in parallel regions. See the example
below.
```mlir
// Optimize with mlir-opt --pass-pipeline="builtin.module(inline)" to trigger the inlining bug.
module {
// runner calls kernel(thread_idx, byval_struct, output)
// After inlining, the alloca for the byval struct gets placed in the outer
// region (shared by all threads) instead of inside the scf.forall body.
// This is a bug: each thread should have its own copy, but they all share
// the same alloca.
llvm.func hidden @runner(%arg0: !llvm.ptr {llvm.byval = !llvm.struct<(f32)>}, %arg1: !llvm.ptr) {
%c0 = arith.constant 0 : index
%c1024 = arith.constant 1024 : index
%c1 = arith.constant 1 : index
scf.forall (%i) = (%c0) to (%c1024) step (%c1) {
%idx = arith.index_cast %i : index to i64
llvm.call @kernel(%idx, %arg0, %arg1) : (i64, !llvm.ptr, !llvm.ptr) -> ()
}
llvm.return
}
// kernel uses the byval struct as writable thread-local scratch space:
// 1. Writes thread_id into the local copy
// 2. Reads it back and stores to output
// After buggy inlining, all threads share the same alloca, so thread A's
// store is overwritten by thread B before thread A reads it back.
// Expected: output[i] == float(i). Actual: non-deterministic.
llvm.func hidden @kernel(%arg0: i64, %arg1: !llvm.ptr {llvm.byval = !llvm.struct<(f32)>}, %arg2: !llvm.ptr) {
%thread_id_f32 = llvm.sitofp %arg0 : i64 to f32
// BUG: after inlining, %arg1 is a shared alloca, concurrent threads

[Flang][OpenMP] Fix close map flag propagation for derived types in USM (#185330)
This fixes a bug in USM mode where the `close` map type modifer was
attached to some `map.info.op`'s corresponding to user-defined type
members while the parent type instance itself is not marked as `close`.
This fix ensures that if a parent record type map does not have the
'close' flag, it is cleared from its members as well, maintaining
consistency.
Gemini was used to create tests. AI generated test code was reviewed
line-by-line by me. Which were derived from a reproducer I was working
with to debug the issue.

[MLIR][OpenMP] Prevent teams reductions from deadlocking (#184625)

```f90
integer :: i, x
!$omp teams distribute reduction(+:x)
do i=1, 10
x = x + 1
end do
```
Preventing a redundant barrier from being added in that case addresses
this issue. Synchronization is already being handled by the
`__kmpc_reduce` and `__kmpc_end_reduce` runtime calls for the host, and
by the OMPIRBuilder-generated `_omp_reduction_inter_warp_copy_func`
function for GPUs.

When we update use-def edges the DAG gets notified to update the
UnscheduledSuccs counters. However, if either edge node is already
scheduled we should not update UnscheduledSuccs because the
UnscheduledSuccs counter value should be treated as "undefined" after a
node has been scheduled, i.e., it's value has a meaning only before the
node gets scheduled.

[mlir] Fix crash in ForwardDominanceIterator when encountering graph regions (#185043)
ForwardDominanceIterator<NoGraphRegions=true> was asserting when it
encountered a region without SSA dominance (a "graph region"), such as
scf.forall.in_parallel's body. This crash was triggered by
-test-ir-visitors when walking functions that contain graph-region ops.
Change the behavior of ForwardDominanceIterator<true> and
ReverseDominanceIterator<true> to silently skip graph regions instead of
asserting, and update the documentation accordingly. This matches the
intended semantics of the NoGraphRegions flag: the traversal simply does
not enumerate blocks/ops inside such regions.

[MLIR][LLVM] Fix crash in LLVMFunctionType::clone when erasing void function results (#185093)
LLVMFunctionType::clone(inputs, results) was asserting that
results.size() == 1, which caused a crash (later changed to return
null/failure) when erasing results from a void llvm.func via
FunctionOpInterface::eraseResults.
For LLVM function types, an empty results range maps to void return: the
FunctionOpInterface represents void llvm.func with 0 results, while the
underlying LLVMFunctionType stores an explicit LLVMVoidType. When
erasing all results (or no-op erasing 0 results from a void function),
the interface passes an empty TypeRange to clone(), which should produce
a void function type.
Fix by accepting an empty results range in LLVMFunctionType::clone() and
mapping it to LLVMVoidType. More than one result remains invalid.

This patch takes into account the option setting when inlining
max/minval intrinsics. It is not an NFC change for Flang, because:
* Inlining for integer types now uses arith.max/minsi operations.
* We do not mark the reduction loops as `unordered`
under `reassoc` FMF. I think this was not quite correct.
Otherwise, the default Legacy setting should produce the same
MLIR as before.

[DA] Test AddRecs are nsw before strong SIV test (#183421)
Currently Strong SIV test, does not check that the AddRecs involved do
not overflow. This is required for correctness of the tests. Strictly
speaking, the range-based independence check in Strong SIV relies on
SCEV which internally takes care of potential overflows, so this is
mainly needed for the divisibility test and distance/directions
calculations, but putting the test early in the function covers all the
cases anyways.

[CIR] Fix spurious MemRead on pure pointer-arithmetic ops (#185154)
Remove incorrect [MemRead] annotations from seven CIR ops that only
perform pointer arithmetic, and add the Pure trait where missing.
- VTableGetVPtrOp computes the address of the vptr slot within an
object. Since the vptr is always at offset zero, this is a bitcast —
confirmed by the lowering which does replaceOp(op, srcVal). No memory
access.
- VTableGetVirtualFnAddrOp takes an already-loaded !cir.vptr value and
an index, computes the address of the nth vtable entry. Lowers to a
GEPOp. No memory access.
- VTableGetTypeInfoOp takes an already-loaded !cir.vptr value, computes
the address of the type_info entry at a known ABI offset. Pointer
arithmetic only. No memory access.
- GetMemberOp computes the address of a struct/class member given a base
pointer and a constant index. Lowers to GEPOp (struct/class) or
BitcastOp (union). No memory access.
- GetRuntimeMemberOp computes a member address using a runtime
pointer-to-data-member value. Lowers to CastOp + PtrStrideOp (byte-level
pointer arithmetic). No memory access.
- BaseClassAddrOp computes the base class address from a derived class
pointer using a byte offset. Lowers to GEPOp/BitcastOp with a null check
when needed. No memory access.
- DerivedClassAddrOp computes the derived class address from a base
class pointer using a negative byte offset. Lowers to GEPOp with a null
check when needed. No memory access.
In all cases, the actual memory reads are performed by separate cir.load
ops that follow these address computations.

From
https://github.com/llvm/llvm-project/pull/169225#issuecomment-4024377289:
There was a dependency cycle involving the C++ language runtime:
```
//lldb/source/Plugins/TypeSystem/Clang:Clang ->
//lldb/source/Plugins/ExpressionParser/Clang:Clang ->
//lldb/source/Plugins/LanguageRuntime/CPlusPlus:CPlusPlus ->
//lldb/source/Plugins/TypeSystem/Clang:Clang
```
`ExpressionParserClang` doesn't need to depend on the C++ language
runtime. It only included a file, but didn't use it. This PR removes
that dependency.

[TableGen] Add let append/prepend syntax for field concatenation (#182382)
## Motivation
LLVM TableGen currently lacks a way to **accumulate** field values
across class hierarchies. When a derived class sets a field via `let`,
it completely replaces the parent's value. This forces users into
verbose workarounds like:
```tablegen
class Op { // This is generic MLIR Base
code extraClassDeclaration = ?;
}
// Some Generic shared base
class MyShared1OpClass : Op {
code shared1ExtraClassDeclaration = [{ some generic code 1 }];
}
class MyShared2OpClass : MyShared1OpClass {
code shared2ExtraClassDeclaration = [{ some generic code 2 }];
}
def MyOp : MyShared2OpClass {
// need to manually concatenate shared code
let extraClassDeclaration =
shared1ExtraClassDeclaration
# shared2ExtraClassDeclaration
# [{ additional specialized code }];
}
```
Instead I propose a more natural incremental solution without
unnecessery intermediate definitions:
```
class Op {
code extraClassDeclaration = ?;
}
class MyShared1OpClass : Op {
let append extraClassDeclaration = [{ some generic code 1 }];
}
class MyShared2OpClass : MyShared1OpClass {
let append extraClassDeclaration = [{ some generic code 2 }];
}
def MyOp : MyShared2OpClass {
let append extraClassDeclaration = [{ additional specialized code }];
}
```
This is especially painful in MLIR, where dialect authors want base
op/type/attribute classes to inject shared C++ declarations into all
derived definitions. I attempted to solve this in PR
https://github.com/llvm/llvm-project/pull/182265 with MLIR-specific
`inheritableExtraClassDeclaration`/`Definition` fields, but as
@joker-eph [pointed
out](https://github.com/llvm/llvm-project/pull/182265#discussion_r2098718600),
this is ad-hoc -- the same inheritance problem exists for `traits`,
`arguments`, `results`, and any other list/string/dag field. Rather than
adding `inheritable*` variants per field, we should solve this at the
language level.
## Design
This PR adds two new modifiers to the `let` statement: **`append`** and
**`prepend`**.
```tablegen
class Base {
list<int> items = [1, 2];
string text = "hello";
dag d = (op);
}
def Example : Base {
let append items = [3, 4]; // items = [1, 2, 3, 4]
let prepend items = [0]; // items = [0, 1, 2]
let append text = " world"; // text = "hello world"
let prepend text = "say "; // text = "say hello"
let append d = (op 3:$a); // d = (op 3:$a)
}
```
### Supported types
| Field type | Operation | Concat operator |
|---|---|---|
| `list<T>` | append/prepend | `!listconcat` |
| `string` / `code` | append/prepend | `!strconcat` |
| `dag` | append/prepend | `!con` |
| Other (`bit`, `int`, `bits`) | -- | Error |
### Semantics
- **`let append`** concatenates the new value **after** the current
value
- **`let prepend`** concatenates the new value **before** the current
value
- If the current value is **unset** (`?`), the new value is used
directly
- A plain **`let`** (without modifier) still replaces, allowing opt-out
from accumulated values
- Works in both **body-level** (`def Foo { let append ... }`) and
**top-level** (`let append ... in { }`) contexts
### Multi-level inheritance
Accumulation works naturally across inheritance chains:
```tablegen
class Base {
list<int> items = [1, 2];
}
class Middle : Base {
let append items = [3]; // items = [1, 2, 3]
}
def Leaf : Middle {
let append items = [4]; // items = [1, 2, 3, 4]
}
```
### Multiple inheritance
TableGen supports multiple inheritance (`def D : A, B { ... }`), where
parent classes are processed left to right and the **last parent class's
value wins** for any shared field. `let append`/`let prepend` operates
on whatever value the field has *after* inheritance resolution — it does
not accumulate across sibling parents:
```tablegen
class A { list<int> items = [1, 2]; }
class B { list<int> items = [3, 4]; }
def D : A, B {
let append items = [5]; // items = [3, 4, 5] (A's value is lost)
}
```
This also applies to diamond inheritance:
```tablegen
class Base { list<int> items = [1]; }
class Left : Base { let append items = [2]; } // [1, 2]
class Right : Base { let append items = [3]; } // [1, 3]
def D : Left, Right {
let append items = [4]; // items = [1, 3, 4] (Left's [2] is lost)
}
```
This is consistent with how plain `let` works with multiple inheritance
— it is the standard last-writer-wins rule. Users who need accumulation
from multiple parents should use a single-inheritance chain instead.
## Backward compatibility
This proposal is **fully backward compatible**. The keywords `append`
and `prepend` are implemented as **context-sensitive keywords** — they
are only recognized as modifiers when they appear immediately after
`let` (in both body-level and top-level contexts). In all other
positions, `append` and `prepend` remain valid identifiers and can be
used as field names, class names, def names, etc. This means:
- No existing `.td` files (in-tree or out-of-tree) will break
- Fields named `append` or `prepend` continue to work: `let append
append = [5];` is valid (the first `append` is the modifier, the second
is the field name)
- The parser checks for the identifier string value after `let`, not for
a reserved token

[HLSL][Matrix] Make HLSLElementwiseCast respect matrix memory layout (#184429)
Fixes #184379
Changes the implementation of HLSLElementwiseCast to respect matrix
memory layout.
The new implementation reads from the `LoadList` array in row-major
order as opposed to column-major in the old implementation, which makes
more sense because `LoadList` is always interpreted in row-major order
when read as a matrix.
The writes to the allocation `V` for the destination matrix now respects
the default matrix memory layout.

The group size is easier, so it's weird that this wasn't implemented
first.

[libc] Use unsigned char in strcmp, strncmp, and strcoll comparisons (#185393)
According to section 7.24.1 of the C standard, character comparison in
string functions must be performed as if the characters had the type
`unsigned char`.
The previous implementations of `strcmp`, `strncmp`, and `strcoll` were
doing a direct subtraction of `char` values. On platforms where `char`
is signed, this resulted in incorrect negative values being returned
when characters exceeding 127 were being compared.
This patch fixes the comparison functions to explicitly cast the
character values to `unsigned char` prior to computing their difference.
It also adds regression tests to ensure the comparison behaves correctly
for ASCII values greater than 127.

[mlir][OpenACC] Normalize loop bounds in convertACCLoopToSCFFor for negative steps (#184935)
`convertACCLoopToSCFFor` was passing `acc.loop` bounds directly to
`scf.for`, which produces an `scf.for` with a negative step when the
source is a Fortran DO loop counting down (e.g. `DO k = n, 1, -1`).
Since `scf.for` requires a positive step, this generated invalid IR that
caused downstream crashes during LLVM lowering.
`convertACCLoopToSCFParallel` already normalizes all loops
unconditionally to `lb=0, step=1, ub=tripCount`, but
`convertACCLoopToSCFFor` did not. This patch applies the same
normalization to `convertACCLoopToSCFFor`, with IV denormalization in
the loop body (`original_iv = normalized_iv * orig_step + orig_lb`), and
lets later passes fold away constants.

[clang][ssaf] Implement Entity Linker CLI and patching for JSON Format
This PR implements Entity ID patching for the JSON serialization format
and introduces `ssaf-linker`, a command-line tool that drives the
`EntityLinker`.
1. Entity ID references inside summary blobs use the sentinel
representation `{"@": <uint64>}`. Patching walks the JSON value tree
recursively, recognizes sentinels, and rewrites their indices using the
`EntityResolutionTable` provided by the linker.
2. An object with an `@` key but extra keys `(size != 1)`, an `@` value
that is not a valid `uint64`, and an entity ID not present in the
resolution table, lead to patching errors.
3. `JSONFormat::EntityIdConverter` is replaced with two `function_ref`
typedefs to eliminate the wrapper class.
4.`ssaf-linker` is implemented in `clang/tools/ssaf-linker/` and gets
built at `bin/ssaf-linker`.
5. lit tests check CLI, verbose output, timing output, validation
errors, I/O errors, linking errors, and successful linking.

[HLSL] Implement Texture2D default template (#184207)
The Texture2D type has a default template of float4. This can be written
in a couple way: `Texture2D<>` or `Texture2D`. This must be implemented
for consistenty with DXC in HLSL202x.
To implement `Texture2D<>` we simply add a default type for the template
parameter.
To implement `Texture2D`, we have to add a special case for a template
type without a template instantiation. For HLSL, we check if it is a
texture type. If so, the default type is filled in.
Note that HLSL202x does not support C++17 Class Template Argument
Deduction, so we cannot use that feature to give us `Texture2D`.
See https://github.com/llvm/wg-hlsl/pull/386 for alternatives that were
considered.
Part of #175630.

to the bare keyword style used by other CIR ops like cir.cast:
`cir.cmp gt %a, %b : !s32i`
The result type (!cir.bool) is now automatically inferred as it is
always cir::BoolType.

[AMDGPU] Cgscc amdgpu attributor boilerplate NFC (#179719)
This PR is adding a boilerplate of CGSCC AMDGPUAttributor pass
(amdgpu-attributor-cgscc) by doing refactoring from the existing Module
AMDGPUAttributor pass (amdgpu-attributor).
CGSCC AMDGPUAttributor pass sets `AttributorConfig.IsModulePass =
false`, and make Attributor's `Functions` set contain only functions in
a SCC.
The main implementations of abstract attributes have not changed - NFC.
Subsequently, in future work some of the AMDGPU abstract attributors
might move to be handled by CGSCC pass.

Centralize prefetch target storage in MachineFunction. (#184194)
### Prefetch Symbol Resolution
Based on this
[suggestion](https://discourse.llvm.org/t/rfc-code-prefetch-insertion/88668/29?u=rlavaee),
we must identify if a prefetch target is defined in the current module
to avoid **undefined symbol errors**. Since this occurs during
sequential **CodeGen**, we must rely on function names rather than IR
Module APIs.
**Key Changes:**
* **`MachineFunction` Integration:** Added a `PrefetchTargets` field
(with serialization) to track all targets associated with a function.
* **Guaranteed Emission:** All prefetch targets are now emitted
regardless of basic block or callsite index matches to ensure the symbol
exists.
* **Fallback Placement:** Targets with non-matching callsite indices are
emitted at the end of the block to resolve the reference.

[RFC][mlir] Resource hierarchy for MLIR Side Effects. (#181229)
This patch allows creating a hierarchy of `SideEffects::Resource`s by adding
a virtual `getParent()` method, so that effects on *disjoint* resources
can be proven non-conflicting. It also adds virtual `isAddressable()` method
that represents a property of a resource to be addressable via a pointer
value. The non-addressable resources may not be affected via any pointer.
This is unblocking CSE, LICM and alias analysis without per-pass
special-casing.

[SLP] Fix misvectorization in commutative to non-commutative conversion (#185230)
**Summary**
Fixes a miscompilation where commutative operations (e.g., or, and, mul)
with a left-hand side constant were incorrectly transformed into
non-commutative operations (e.g., shl, sub).
**The Problem**
In `BinOpSameOpcodeHelper::getOperand`, when a constant is at `Pos ==
0`, the helper was failing to swap operand order for new non-commutative
target opcodes. This resulted in inverted logic, such as transforming
`or 0, %x` into `shl 0, %x` (resulting in 0) instead of the correct `%x
<< 0`.
**The Fix**
The existing logic only protected the Sub opcode. This patch generalizes
the fix to all non-commutative instructions by using
`!Instruction::isCommutative(ToOpcode)`. This ensures that for any
directional operation, the variable is correctly placed on the LHS and
the constant on the RHS.
**Changes**
SLPVectorizer.cpp: Replaced the specific Sub check with a general
isCommutative check.
Regression Test: Added lhs-constant-non-cummutative.ll to cover shl,
sub, and ashr targets.
Fixes #185186

- Accept both .rst and .md source suffixes
- Configure Furo source_repository/source_branch/source_directory for
"Edit this page" links pointing to GitHub
- Wire _static/copybutton.{js,css} for copy-to-clipboard buttons on code
blocks (no new pip dependency; can migrate to sphinx-copybutton later
once it's in requirements-hashed.txt)
- Exclude plan-docs.md and Helpers/ from Sphinx processing
index.rst
- Rewrite landing page: remove apologetic "not fully complete" note, add
"What Works Today" section with concrete supported use cases, honest
caveat that full C stdlib coverage is still in progress
- Restructure hidden toctrees into five captioned sidebar groups: "Using
LLVM-libc", "Platforms" (GPU/UEFI promoted to top-level),
"Implementation Status", "Development", "Links"
New files
- docs/_static/copybutton.{js,css}: lightweight copy button for code
blocks
- docs/_static/custom.css: add status badge styles (.badge-complete
etc.) for use with Helpers/Styles.rst substitutions in later phases
Prepare for future status badges:
- docs/Helpers/Styles.rst: RST substitution definitions for status
badges (|Complete|, |Partial|, |InProgress|, |NotStarted|, |GPUOnly|,
|LinuxOnly|) — excluded from toctree, available for Phase 5+ pages
- docs/dev/building_docs.rst: new page covering prerequisites (with
Debian apt-first instructions), CMake flags, ninja docs-libc-html, the
docgen auto-generation pipeline, and troubleshooting
Removed
- docs/README.txt: stale file claiming Sphinx 1.1.3, not in any toctree;
superseded by docs/dev/building_docs.rst
Cleanups
- Remove redundant ".. contents:: Table of Contents" directives from 16
RST files (Furo renders its own per-page TOC in the sidebar)
- Remove same directive from libc/Maintainers.rst (pulled into docs via
include)

[Clang] Update the 'gpuintrin.h' lane scan handling (#185451)
Summary:
This patch uses a more efficient algorithm for the reduction rather than
a divergent branch. We also provide a prefix and suffix version, the sum
is now just the first element of this.
This changes the name to this, which is technically breaking but I don't
think these were really used in practice and it's a trivial change based
on the clang version if it's really needed..

[arm64ec] Fix missing sret return in Arm64EC entry thunks for large struct returns (#185452)
When an Arm64EC function returns a struct by value that is too large for
x64's `RAX` (>8 bytes), the entry thunk synthesizes a hidden sret
pointer parameter for the x64 side. However, this
parameter was never marked with the sret attribute, so ISel did not copy
its value into `x8` (the Arm64EC mapping of `RAX`) on return. This
caused the x64 caller to see a garbage pointer in `RAX` instead of the
return buffer address.
The change adds the sret attribute to the thunk's synthesized pointer
parameter, so that `LowerFormalArguments` saves it and `LowerReturn`
restores it to `x8` before the tail call to `__os_arm64x_dispatch_ret`.
Fixes #185390

[libc] Add more macro/type declarations to Elf headers. (#185348)
* Add several `AT_` macro values from `<sys/auxv.h>`. In particular,
this allows to make internal Linux auxv header parsing more hermetic by
removing one of Linux header includes.
* Add constants between `DT_ADDRNGLO` and `DT_ADDRNGHI`, in particular
`DT_GNU_HASH`, which is de-facto standard on many platforms.
* Add `Elf32_auxv_t` and `Elf64_auxv_t` types which define the auxv
entries and can be used by VDSO parsing code. Note that this PR doesn't
yet update libc's own Linux auxv header support (in
`src/__support/OSUtil/linux/auxv.h`).
This fixes some of the missing definitions when building code working
with Elf files, such as Abseil's debugging support in
https://github.com/abseil/abseil-cpp/tree/master/absl/debugging/internal.

[Offload][AMDGPU] Fix RPC server on mixed w32 w64 workloads (#185496)
Summary:
This was a regression from the original LLVM-gpu-loader. We used to
handle `-mwavefrontsize64` correctly in the loader by over-allocating
memory and just leaving the upper 32-bits masked off. In order to handle
this in offload we need to scan loaded kernels to see how much memory we
need to allocate. This should be safe, the protocol is designed to
handle an arbitrary size and worst-case this just wastes space.

[SelectionDAG] Use ExpandIntRes_CLMUL to expand vector CLMUL via narrower legal types (#184468)
Reuse the ExpandIntRes_CLMUL identity to expand vector
CLMUL/CLMULR/CLMULH on wider element types (vXi16, vXi32, vXi64) by
decomposing into half-element-width operations that eventually reach a
legal CLMUL type.
Three generic strategies in expandCLMUL:
1. Halve: halve element width (e.g. v8i16 -> v8i8 on AArch64)
2. promote to double : zext to wider type if CLMUL is legal there (e.g.
x86)
3. Count widen: pad with undef to double element count (e.g. v4i16 ->
v8i16)
A helper canNarrowCLMULToLegal() guides strategy selection and prevents
circular expansion in the CLMULH bitreverse path.
Also add Custom BITREVERSE lowering for v4i16/v8i16 on AArch64 using
REV16+RBIT, which the CLMULH expansion relies on.

[SPIR] Do not warn on 64-bit atomics (#185502)
Summary:
SPIR-V's Int64Atomics capability is not dependent on its addressing mode
as far as I am aware. These 32-bit SPIR targets already claim to support
the cl_khr_int64 atomics and we already emit 64-bit atomics in the
backend. Additionally, this is already accepted as a hack due to the
fact that the host will increase it in offloading usage. I do not see a
reason to keep these at 32, which causes numerous warnings inside of the
`libclc` build.

[HLSL] Fix interleaved vector and matrix return types in AST dump (#184888)
HLSL vector and matrix types were previously printed with their closing
syntax (', N>') in 'printAfter', causing them to interleave with
function
parameters when used as return types (e.g., 'vector<float (args), 4>').
This change moves the HLSL vector and matrix closing syntax into
'printBefore' when 'UseHLSLTypes' is enabled, ensuring the type is
printed completely before the parameter list.
Note that address space qualifiers are now printed after the type
(e.g., 'vector<float, 4>hlsl_device'). This is because
'canPrefixQualifiers' in 'TypePrinter.cpp' returns false for these
types.
We cannot easily change this to check 'UseHLSLTypes' because
'canPrefixQualifiers' is a static method and does not have access to the
PrintingPolicy at that point.
Fixes interleaved output in HLSL AST tests.
Fixes https://github.com/llvm/llvm-project/issues/114868.

[DA] Fix overflows when calculating Delta in the Weak Zero SIV tests (#184997)
Add overflow checks when computing `Delta` in the Weak Zero SIV tests.
The tests bail out if we cannot prove that the `Delta` computation does
not overflow. These calculations are also moved later so that some
analyses that do not require these checks can run first.
Fix part of the test cases added in #164246.

[Clang] Track alloca element types to avoid getAllocatedType() calls (#181740)
Store alloca element types alongside alloca pointers in Clang's CodeGen,
eliminating the need to query getAllocatedType() later.
Changes:
- CodeGenFunction.h: Modified DominatingLLVMValue::saved_type to track
type Uses Type==nullptr as sentinel for "not saved" instead of separate
bool. Fixes a bug where it previously tried to use the addrspacecasted
value constructor and later cast it to an alloca.
- CGHLSLRuntime.cpp: Changed OutputSemantic map to store (Value*, Type*)
pairs to trivially remove getAllocatedType calls.

[clang] Adjust -pedantic-errors -WX/-Wno-error=X interaction (#184756)
While -Wno-long-long suppresses -pedantic-errors diagnostics in both GCC
and Clang, GCC -Wno-error=long-long emits warnings while Clang still
emits errors.
```
% echo 'long long x = 0;' | gcc -std=c89 -pedantic-errors -Wno-error=long-long -x c -fsyntax-only -
<stdin>:1:6: warning: ISO C90 does not support 'long long' [-Wlong-long]
% echo 'long long x = 0;' | clang -std=c89 -pedantic-errors -Wno-error=long-long -x c -fsyntax-only -
<stdin>:1:1: error: 'long long' is an extension when C99 mode is not enabled [-Werror,-Wlong-long]
1 | long long x = 0;
| ^
1 error generated.
```
The order of -pedantic-errors and -Wno-error=long-long does not matter.
Two fixes to how extension diagnostics interact with -pedantic-errors
in getDiagnosticSeverity():
1. -Wno-error=X now downgrades -pedantic-errors diagnostics to warnings.
setDiagnosticGroupWarningAsError() sets HasNoWarningAsError but not
IsUser, so the ExtBehavior upgrade would re-promote to error. When
HasNoWarningAsError is set, cap the ExtBehavior upgrade at Warning.
2. -Wfoo no longer prevents -pedantic-errors from upgrading to error.
Previously, -Wfoo set IsUser which blocked the ExtBehavior upgrade
entirely. Now only -Wno-foo (IsUser + Ignored) blocks the upgrade,
matching GCC behavior.
```
% echo 'long long x = 0;' | myclang -std=c89 -pedantic-errors -Wno-error=long-long -x c -fsyntax-only -
<stdin>:1:1: warning: 'long long' is an extension when C99 mode is not enabled [-Wlong-long]
1 | long long x = 0;
| ^
1 warning generated.

[SampleProfileMatcher] Add direct basename early matching for orphan functions (#184409)
When user code changes function signatures (e.g., adding/removing
parameters), the C++ mangled name changes while the base function name
stays the same. The existing stale profile CG matching can only recover
renamed functions when they appear as callees of already-matched
callers. If the caller has no profile (e.g., fully inlined in the
profiled binary, or from a different TU not loaded), the renamed callee
is never discovered and gets zero profile data.
Add `matchFunctionsWithoutProfileByBasename()` that pairs orphan IR
functions (no profile) with unused top-level profile functions by
demangled basename, without requiring a matched caller in the call
graph.
This direct basename matching runs before CG matching and writes to
`FuncToProfileNameMap`. CG matching can later overwrite these entries
(since `SymbolMap` is not updated until `UpdateWithSalvagedProfiles`),
so a contextually better CG match is not blocked.
An unambiguous 1:1 mapping is enforced: a basename is only matched when
exactly one orphan IR function and exactly one profile candidate share
it. This eliminates false positives from common/short basenames while
preserving matches for unique function names that are the primary target
of this optimization.

[SampleProfileMatcher] Flatten profiles loaded on demand (#184255)
Fix an issue that after loading top-level function from profile during
CG matching, it's not flattened. This means the inlined callees of the
loaded nested profile don't get their own entries in
`FlattenedProfiles`, making them undiscoverable by subsequent CG
matching steps.

[ORC] Add WaitingOnGraph record / replay facilities. (#185275)
WaitingOnGraph is critical to the performance of LLVM's JIT (see e.g.
https://github.com/llvm/llvm-project/issues/179611), and these facilities will
make it easier to capture and investigate test cases, and build a performance
regression suite.
WaitingOnGraph::OpRecorder provides an interface for classes that want to
capture the essential WaitingOnGraph operations: simplify-and-emit, and fail.
WaitingOnGraph::simplify and WaitingOnGraph::fail now take an optional
OpRecorder pointer.
WaitingOnGraphOpStreamRecorder (WaitingOnGraphOpReplay.h) is an OpRecorder
implementation that serializes operations to a line-oriented text format on a
raw_ostream. WaitingOnGraphOpReplay provides types and utilities for iterating
over and replaying recorded operations. readWaitingOnGraphOpsFromBuffer returns
an iterator range over the ops in a serialized buffer.
The new ExecutionSession::setWaitingOnGraphOpRecorder method can be used to
install a recorder to capture ops from OL_notifyEmitted and IL_failSymbols.
The llvm-jitlink tool gains two new options:
- -waiting-on-graph-capture <filename> records all WaitingOnGraph operations
during a regular llvm-jitlink invocation.
- -waiting-on-graph-replay <filename> replays the operations from a capture
file. In this mode other arguments are ignored.

Log Message:
-----------
[libc++] Fix strict aliasing violation for `deque::const_iterator` (#136067)
When the allocators use fancy pointers, the internal map of `deque`
stores `FancyPtr<T>` objects, and the previous strategy accessed these
objects via `const FancyPtr<const T>` lvalues, which usually caused core
language undefined behavior. Now `const_iterator` stores `FancyPtr<const
FancyPtr<T>>` instead of `FancyPtr<const FancyPtr<const T>>`, and ABI
break can happen when such two types have incompatible layouts.
This is necessary for reducing undefined behavior and `constexpr`
support for `deque` in C++26, and I currently don't want to provide any
way to opt-out of that behavior.
For `iterator`, the current strategy makes it store
`FancyPtr<FancyPtr<T>>`. But it would make more sense to also store
`FancyPtr<const FancyPtr<T>>` because we never modify the map via
`iterator`.
For some pathological combinations of allocators and fancy pointers, the
rebinding trick doesn't work. These cases are rejected by
`static_assert`.
The existing test coverage seems to be sufficient.

[MC] Rename PrivateGlobalPrefix to InternalSymbolPrefix. NFC (#185164)
The "private global" terminology, likely came from
llvm/lib/IR/Mangler.cpp, is misleading: "private" is the opposite of
"global", and these prefixed symbols are not global in the object file
format sense (e.g. ELF has STB_GLOBAL while these symbols are always
STB_LOCAL). The term "internal symbol" better describes their purpose:
symbols for internal use by compilers and assemblers, not meant to be
visible externally.
This rename is a step toward adopting the "internal symbol prefix"
terminology agreed with GNU as
(https://sourceware.org/pipermail/binutils/2026-March/148448.html).

[LifetimeSafety] Handle escape through assignment to global storage (#181646)
This PR allows for modelling escape of parameters to global storage, and
dangling global storage.
Change summary:
1. Created `GlobalEscapeFact` as a subclass of `OriginEscapesFact`
2. Emit a `GlobalEscapeFact` for all origins with global-storage that
remain live at function exit.
3. Integrated into warning reporting as necessary, introducing the
groups `-Wlifetime-safety-dangling-global` and
`-Wlifetime-safety-dangling-global-moved`
4. Wrote sema tests for escape to a variety of global storage locations.

[LangRef] Specify semantics for non-byte-sized loads and stores (#180739)
LangRef currently specifies that non-byte-sized stores write an
unspecified bit pattern in the "padding", and that performing a
subsequent load with a different bitwidth is "undefined". This means
that storing an i1 value and then loading it as i8, the result is
"undefined" (whatever that is supposed to mean). These semantics are
quite unusual as they depend on the exact type a memory location has
been accessed with previously. I believe that frontends often do not
respect these semantics.
This PR proposes to instead specify that non-byte-sized loads
effectively act like like a byte sized `load` followed by `trunc nuw`,
and non-byte-sized stores act like a `zext` followed by a byte-sized
store. To the best of my knowledge, this matches the legalization
behavior of SDAG.
This does restrict possible codegen choices (e.g. a target couldn't
define these as `sext`/`trunc nsw` instead anymore), but it does not
appear that there is any interest in that in practice, given that SDAG
does not support it to this day.

[flang] Add runtime trampoline pool for W^X compliance (#183108)
Flang currently lowers internal procedures passed as actual arguments
using LLVM's `llvm.init.trampoline` / `llvm.adjust.trampoline`
intrinsics, which require an executable stack. On modern Linux
toolchains and security-hardened kernels that enforce W^X (Write XOR
Execute), this causes link-time failures (`ld.lld: error: ... requires
an executable stack`) or runtime `SEGV` from NX violations.
This patch introduces a runtime trampoline pool that allocates
trampolines from a dedicated `mmap`'d region instead of the stack. The
pool toggles page permissions between writable (for patching) and
executable (for dispatch), so the stack stays non-executable throughout.
On macOS, MAP_JIT and `pthread_jit_write_protect_np` are used for the
same effect. An i-cache flush (`__builtin___clear_cache` on Linux,
`sys_icache_invalidate` on macOS) is performed after each write→exec
transition.
The feature is gated behind a new driver flag, `-fsafe-trampoline` (off
by default), which threads through the frontend into the
`BoxedProcedurePass`. When enabled, the pass emits calls to
`_FortranATrampolineInit`, `_FortranATrampolineAdjust`, and
`_FortranATrampolineFree` instead of the legacy intrinsics. The legacy
path is completely untouched when the flag is off.
The pool is a singleton with a fixed capacity (default 1024 slots,
overridable via `FLANG_TRAMPOLINE_POOL_SIZE`). Slot size varies by
target (32 bytes on x86-64/AArch64, 48 on PPC64, 64 fallback). Each slot
holds a small architecture-specific stub, currently x86-64 (17 bytes,
using `r10` as the nest/static-chain register) and AArch64 (24 bytes,
using `x15`). The implementation compiles on all architectures but will
crash at runtime with a clear diagnostic if trampoline emission is
actually attempted on an unsupported target. This avoids breaking the
flang-rt build on e.g. RISC-V or PPC64.
Freed slots are poisoned (the callee pointer is overwritten with a
sentinel) and recycled into a freelist, so the pool can sustain
long-running programs that repeatedly create and destroy closures.
A few design choices worth calling out:
The runtime avoids all C++ runtime dependencies, no `std::mutex`, no
`operator new`, no function-local statics with hidden guard variables.
Locking is via flang-rt's own `Lock` / `CriticalSection`, memory is via
`AllocateMemoryOrCrash` / `FreeMemory`, and the singleton uses explicit
double-checked locking with a raw pointer. This was done so the
trampoline pool links cleanly in minimal / freestanding flang-rt
configurations.
`_FortranATrampolineFree` calls are inserted immediately before every
`func.return` in the enclosing host function. This is a conservative but
correct strategy. The trampoline handle cannot outlive the host's stack
frame since the closure captures the host's local variables by
reference.
The GNU_STACK note is verified via a dedicated integration test
(`safe-trampoline-gnustack.f90`) that compiles and links a Fortran
program using the runtime path, then inspects the ELF with
`llvm-readelf` to confirm the stack segment is `RW` (not `RWE`).
**Test coverage:**
- `flang/test/Driver/fsafe-trampoline.f90` — flag forwarding (on, off,
default)
- `flang/test/Fir/boxproc-safe-trampoline.fir` — FIR-level FileCheck for
emitted runtime calls
- `flang/test/Lower/safe-trampoline.f90` — end-to-end lowering
- `flang-rt/test/Driver/safe-trampoline-gnustack.f90` — GNU_STACK ELF
verification
Closes #182813

[clang][Index][NFC] Carve out USRGeneration from clangIndex (#185499)
Previously, USRGeneration was implemented by clangIndex. However, that
poses too broad library layering constraints on the ever growing set of
users of a tiny component of it, USRGeneration.
This PR splits that into a small library, called:
clangUnifiedSymbolResolution
Anyone needing USRGeneration could simply link against this without
pulling in everything from clangIndex.
---
Importantly, clangIndex linked against clangFrontend to define its
FrontendAction, and use some ASTUnit APIs. Some users may want to use
USRGeneration but NOT depend on clangFrontend. This new
clangUnifiedSymbolResolution library would solve such circular
dependencies.
PS: There were quite a few cases where libraries could just link against
clangUnifiedSymbolResolution without linking to clangIndex. I've
simplified those cases in this PR, to keep link deps minimal.

[Clang][AArch64] Clarify and simplify SISD intrinsic handling (NFC) (#185285)
Not all AArch64 intrinsics categorized as SISD (Single Instruction
Single Data) are truly SISD. Add comments clarifying this distinction.
Also update EmitCommonNeonSISDBuiltinExpr:
* Move the assert to the top of the function and add a descriptive
message to make the assumptions explicit.
* Remove unnecessary temporary variables (e.g. BuiltinID) and use
SISDInfo directly.
No functional changes intended.

intrinsics work for AMDGPU, but aren't really implemented
for spirv or nvptx. Ideally the intrinsic and/or libm call
would be the default implementation.

[VPlan] Materialize VectorTripCount in narrowInterleaveGroups. (#182146)
When narrowInterleaveGroups transforms a plan, VF and VFxUF are
materialized (replaced with concrete values). This patch also
materializes the VectorTripCount in the same transform.
This ensures that VectorTripCount is properly computed when the narrow
interleave transform is applied, instead of using the original VF
+ UF to compute the vector trip count. The previous behavior generated
correct code, but executed fewer iterations in the vector loop.
The change also enables stricter verification prevent accesses of UF,
VF, VFxUF etc after materialization as follow-up.
Note that in some cases we no miss branch folding, but that should be
addressed separately, https://github.com/llvm/llvm-project/pull/181252
Fixes one of the violations accessing a VectorTripCount after UF and VF
being materialized

[CIR][AArch64] Add support for the remaining `vceqz` builtins (#185440)
Implement the remaining CIR lowerings for the AdvSIMD (Neon)
`vceqz` intrinsic group (bitwise equal to zero).
Most variants of `vceqz` variant were already supported; this patch
completes the rest of the group [1] that was left as a TODO.
Tests for these intrinsics are moved from:
* test/CodeGen/AArch64/neon_intrinsics.c
* test/CodeGen/AArch64/v8.2a-fp16-intrinsics.c
to:
* test/CodeGen/AArch64/neon/intrinsics.c
* test/CodeGen/AArch64/neon/fullfp16,
respectively.
The implementation largely mirrors the existing lowering in
CodeGen/TargetBuiltins/ARM.cpp.

[AMDGPU] Fix GFX1250 hazard: S_SET_VGPR_MSB dropped after
S_SETREG_IMM32_B32 (MODE)
On GFX1250, S_SET_VGPR_MSB immediately after S_SETREG_IMM32_B32
targeting
the MODE register is silently dropped by hardware.
AMDGPULowerVGPREncoding may insert S_SET_VGPR_MSB after a setreg(MODE)
in
Case 2 (size > 12) when imm32[12:19] doesn't match current VGPR MSBs, or
when the next VALU instruction needs different MSBs. Fix by inserting
S_NOP
between the setreg and S_SET_VGPR_MSB to prevent the hazard.
The fix handles two scenarios:
- Case 2 mismatch: S_NOP is inserted directly before S_SET_VGPR_MSB in
handleSetregMode.
- Case 2 match followed by a VALU with different MSBs: a flag
(NeedNopBeforeSetVGPRMSB) is set, and setMode inserts S_NOP before the
next S_SET_VGPR_MSB.
Also adds vcmpx-permlane-vgpr-msb-gfx1250.mir to verify that VGPR
lowering
must run after the hazard recognizer: fixVcmpxPermlaneHazards creates
V_MOV_B32 using high VGPRs that need correct S_SET_VGPR_MSB from the
lowering pass.

completes the remaining cases listed in [1].
Move the corresponding tests from:
* clang/test/CodeGen/AArch64/neon_intrinsics.c
to:

The implementation mirrors the existing lowering in
CodeGen/TargetBuiltins/ARM.cpp. To support this, add the
`emitCommonNeonSISDBuiltinExpr` helper.

[CIR] Ensure strings are null-terminated, better deal with trailing null (#185513)
Our current implementation of string lowering did some work to remove
extra trailing zeros, plus do a 'zero' constant. That is unchanged by
this patch. However, this patch ALSO ensures that we do the 'remove
extra trailing zeros' to remove ALL trailing zeros, which likely has
canonicalization benefits later on.
However, the real benefit of this patch is to make string emission by
default emit a null-terminator, which fixes the virtual table 'name'
field get lowered correctly. We do this by making the builder::getString
function take an argument (true by default) that will ensure we add a
null terminator if necessary.
This reflects the llvm::ConstantDataArray::getString function, which has
the same functionality. However, doing this during lowering seems
incorrect, since the FE is the one that knows whether these null
terminators are necessary. There is not currently an 'opt out' use of
the behavior, but the functionality is left in place to better reflect
the ConstantDataArray::getString function interface.
Note with the tests that this fixes some inconsistencies between LLVM
and OGCG lowering.

[Hexagon] Fix 64-bit funnel shift miscompilation with register shift amounts (#183669)
64-bit regpair shift amounts are treated as signed 7-bits, so a
complement
shift amount of 64 (when the primary amount is 0) is sign-extended to
-64,
reversing the shift direction and producing incorrect results. This
affected
any 64-bit rotate or funnel shift where the runtime shift amount could
be 0
(making the complement 64) or >= 64.
Fix by masking the shift amount to [0, 63] and computing the complement
as
(m - 64), which is always in [-64, -1]. Using lsl/lsr (logical shift)
instructions with this negative amount causes the hardware to reverse
the
shift direction while zero-filling vacated positions:
fshl(a, b, amt) = (a << m) | lsl(b, m - 64) // lsl reverses to lsr
fshr(a, b, amt) = (b >> m) | lsr(a, m - 64) // lsr reverses to lsl
where m = amt & 63. The logical shift instructions (lsl/lsr) are used
instead of arithmetic (asl) because asl with a negative amount performs
an
arithmetic right shift that sign-extends, which would corrupt the result
for negative source values.
When m = 0, the complement amount is -64 (magnitude 64), which shifts
all
64 bits out and produces zero, so the complement term vanishes as
required.

scheduler is using Sched::RegPressure which gives a good input order to begin
with.
It is trying harder with biasing phys regs than GenericScheduler as it also
considers other instructions such as immediate loads directly into phys-regs
produced by the register coalescer. This can hopefully be refactored into
MachineScheduler.cpp.
It has a latency heuristic that is slightly different from the one in
GenericScheduler: It is activated for a specific type of region that have
many "data sequences" consisting of SUs connected only with a single
data-edge that are next to each other in the input order. This is only 3% of
all the scheduling regions, but when activated it is applied on all the
candidates (not just once per cycle). At the same time it is a bit more
careful by checking not only the SU Height against the scheduled latency but
also its Depth against the remaining latency.
It reuses the GenericScheduler handling of weak edges to help copy
coalescing.
It also helps with compare zero elimination as it tries to put a CC-defining
instruction that produces the compare source value above the compare before
any other instruction clobbering CC or the value.
This work was started after observing heavy spilling in Cactus, which was
actually *caused* by GenericScheduler - disabling it (no pre-RA scheduling)
remedied it and gave a 7% improvement in performance on that benchmark. Many
different versions have been tried which has evolved into this initial
simplistic MachineSchedStrategy that does relatively little and yet achieves
double-digit improvements on Cactus and Imagick compared to GenericSched
(which is OTOH 3% better on Blender). There will hopefully be more
improvements added later on as there seems to be potential for it.
It would be very interesting to have other OOO targets try this as well and
perhaps make this available in MachineScheduler.cpp
(A first attempt with improving the pre-RA scheduling was made with #90181,
which however did not materialize in anything actually useful.)

[LLVM][CodeGen][SVE] Implement isel for maximumnum/minimumnum. (#185074)
Patch to add custom lowering for FCANONICALIZE, FMAXNUM_IEEE, and
FMINNUM_IEEE, all of which are required when relying on default
expansion of FMAXIMUMNUM and FMINIMUMNUM.
The lowering is very simple because AArch64's FMAXNM and FMINNM
instructions are IEEE754-2008 compliant, with the implementation
effectively follow the same path take for NEON.
NOTE: Bfloat support will be provided separately.

[SYCL] Correct emission status reporting for function templates declared with SYCL attributes. (#185522)
Commit cf6cc662eeee2b1416430f517850be9032788e39 ([OpenMP][SYCL] Improve
diagnosing of unsupported types usage) customized
`Sema::getEmissionStatus()` to return `Emitted` for a function declared
with the `sycl_kernel` attribute during device compilation. That change
is appropriate, but was inserted before a check for a dependent context
and resulted in `Emitted` being returned instead of `TemplateDiscarded`
for templated functions declared with the attribute. That appears to be
incorrect; templated functions are still discarded.
The customization was extended to include the `sycl_kernel_entry_point`
and `sycl_external` attributes in commit
23e4fe040b67e2dd419652830a87093a93ea1a97 ([SYCL] SYCL host kernel launch
support for the sycl_kernel_entry_point attribute). Those additions are
appropriate, but the effect on templated functions (as opposed to their
instantiations) resulted in the incorrect status being observed in a
downstream fork of Clang.
This change corrects `Sema::getEmissionStatus()` to once again
unconditionally return `TemplateDiscarded` for templated functions.

[clang][Dependency Scanning] Reland Fix the In-Memory Buffer Used for By-Name Scanning (#183396) (#185474)
This PR fixes two issues of the in-memory buffer we use for the input
file when a dependency scanner performs by-name queries.
First, it renames the buffer. The temporary file was named
`ScanningByName-%%%%%%%%.input`, which leads to weird diagnostics such
as
```
ScanningByName-2d42a1e9.input:1:1: fatal error: could not build module 'X'
```
This PR changes the name of the file buffer, so we get diagnostics such
as
```
module-include.input:1:1: fatal error: could not build module 'X'
```
which is more indicative.
Additionally, this PR fixes a bug where the source location may overflow
the temporary buffer by creating a 64k empty string which the temporary
buffer occupies. When the source location overflows, the diagnostics
could point to some random file that comes after the fake file and is
incorrect.
Currently, the maximum number of unique names from Apple's SDKs is
around 3000. A 64k buffer per dependency scanning worker gives us around
20x capacity per worker (which scans fewer names than 3000 when the
scanning is done in parallel). A fatal error is added to catch
overflows.

[MLIR][Python] Add get_parent_of_type helper (#185512)
The `op.parent` only returns the immediate parent, in which case
downstream users have to traverse the operation by themselves to find a
specific type op.
This PR adds a python function `get_parent_of_type()` to mlir.ir to
provide an API to do so.
The function mirrors the implementation here:
https://github.com/llvm/llvm-project/blob/main/mlir/include/mlir/IR/Operation.h#L257-L273.
Instead of creating a new binding, reimplement it in python using
`isinstance()` is simpler.

This commit brings improves
`ProcessFreeBSDKernelCore::DoUpdateThreadList()` by porting features
from KGDB (`fbsd_kthr.c` specifically) and adding fixes. It includes:
1. Validate `stopped_cpus` before accessing `stoppcbs`
2. Check bounds for `mp_maxid`
3. Check errors when reading proc from memory
4. Detect new architectures from previous PRs (ppc64le, riscv64, arm)
which weren't handled correctly in `DoUpdateThreadList()`.
Fallbacks for finding offsets aren't ported since kernel exposes
hardcoded variables for offsets starting from FreeBSD 11. Fallbacks
aren't needed as LLDB 23 only supports FreeBSD 14 and later.

[Clang] Add more scan / reduce operations to 'gpuintrin.h' (#185525)
Summary:
This builds off the pattern to add support for more of the standard
operations. The reductions could concievably use the AMDGPU builtins
later once we can enable DPP or other optimizations.

[X86] Fix wrong ImmT in several instructions and add assertion (#185461)
Follow-up to #185254:
Several instructions inherited ImmT=Imm8 from *Ii8Base/*Ii8 classes
without having an actual immediate operand. This made
X86MCCodeEmitter::emitMemModRMByte compute ImmSize=1 instead of 0:
```
int ImmSize = !Disp.isImm() && X86II::hasImm(TSFlags)
? X86II::getSizeOfImm(TSFlags)
: 0;
```
biasing RIP-relative displacements by one byte (e.g. foo-0x5 instead
of foo-0x4).
Affected instructions:
- VCVTHF82PH (via AVX512XDIi8Base): has memory forms, wrong relocations
- V[U]COMIS{S,D,H}Zrrb (via AVX512P{S,D}Ii8Base): reg-only, latent
- MMX_MOV{DQ2Q,Q2DQ}rr and variants (via MMXSDIi8/MMXS2SIi8): reg-only,
latent
Fix by replacing the *Ii8Base/*Ii8 classes with their prefix-only
equivalents (TB, XD, XS, PD) and setting ExeDomain explicitly where
needed.
Add an assertion in encodeInstruction to catch future TSFlags/operand
ImmType mismatches: after consuming all operands in the Form-specific
switch, if `hasImm(TSFlags)` is true but `RemainingOps` is 0 and the
Form
isn't one that handles immediates internally (RawFrm, AddCCFrm,
RawFrmImm8, RawFrmImm16, RawFrmMemOffs), the assertion fires. For
example, `VCOMISDZrrb` has `Form=MRMSrcReg` and `ImmT=Imm8` (from
AVX512PDIi8Base), but after consuming both XMM operands CurOp equals
NumOps, leaving RemainingOps=0 with no immediate to emit.

This PR upstreams a piece of infrastructure from Swift's LLVM fork. This
allows controlling behavior of the dependency scanner, e.g. modifying
the primary compiler invocation and modifying compiler instances (the
primary one and for imported modules). This will be used to implement
modules support in the CAS-based compilation caching mode.

In AArch64 calls have a +/-128MB range
(https://developer.arm.com/documentation/ddi0602/2025-12/Base-Instructions/BL--Branch-with-link-).
In cases where the .text is larger than that, the linker adds functions
that just jumps to the sanitizer functions and places them to some code
location where the rest of the binary can call it. These functions have
the prefix __AArch64ADRPThunk__.
This commit marks calls to this function as coverage points.

[copmiler-rt] Initial support for building profile library on the GPU (#185552)
Summary:
As suggested in https://github.com/llvm/llvm-project/pull/177665, we
should build a GPU version of the compiler-rt profile library instead of
writing it in-line in the lowering. This PR does not define anything GPU
specific, it simply re-uses the baremetal handling. Later PRs will
prevent the GPU specific handling we would want to do to optimize
counter handling on the GPU.
Note that this will require using the cache file, or setting these
options
manually for existing users. Hopefully if people are using the cache
file
as they should it won't break anything.

using coverage, and by asserting that no tests in the existing test
suite fails if we insert an `abort()` at this line).
We propose a test that covers this line. We demonstrate the test by
inserting an `abort()` at that line in commit
[#3cb65cf](https://github.com/llvm/llvm-project/pull/185430/changes/3cb65cf4451b5e728fb1e4968ba78b8e83d74220).
Running all tests shows that only our proposed test fails in the
presence of the abort. We'll remove the abort before merging.
This is the only test that fails in the presence of the abort (our new
test) -- it will pass once we remove the abort:

[mlir][acc] Add ACCComputeLowering pass (#185501)
Introduce a pass that lowers OpenACC compute constructs to a
representation that separates the data environment from the compute body
and prepares for parallelism assignment and privatization at the right
granularity.
- Decompose acc.parallel, acc.serial, and acc.kernels into
acc.kernel_environment and acc.compute_region. Launch arguments
(num_gangs, num_workers, vector_length) are turned into acc.par_width
and passed as compute_region launch operands.
- Convert acc.loop to SCF based on context: unstructured loops to
scf.execute_region; sequential (serial or seq) to scf.parallel with
par_dims=sequential; auto loops to scf.for (with collapse when
multi-dimensional); orphan loops to scf.for; independent loops in
parallel/kernels to scf.parallel with par_dims from the GPU mapping.

[lldb] Have ObjectFile::FindPlugin send a copy of the DE (#185727)
ObjectFile::FindPlugin iterates over plugins to find one that can handle
the binary provided. It is currently sending the one DataExtractorSP to
each subclass, but some subclasses may modify this DataExtractor during
their processing, e.g. calling DataExtractor::SetData on it, and I think
it is safer to isolate these with a copy of the DataExtractor so the
order the plugins are tried cannot possibly change behavior.

[SPIR-V] Add lowering for G_FPOWI (#185454)
This fixes an assertion I was hitting in the fragment density map sample
in Vulkan Samples. In starfield.frag.hlsl, we have
float starCol = pow((rnd - threshhold) / (1.0 - threshhold), 16.0);
The optimizer recognizes 16.0 as a whole number and converts the call to
`llvm.powi`. The backend goes on to fail with:
fatal error: error in backend: cannot select: %46:fid(s64) = nnan ninf
nsz arcp afn reassoc G_FPOWI %44:fid, %45:iid(s64) (in function:
_Z9starFieldDv3_f)
On Vulkan, there is no integer-exponent for pow. This patch lowers it by
converting the exponent to float and calling GLSL.std.450's Pow.

[CIR] Add abstract delete operation without AST attribute (#185538)
This introduces the cir.delete_array operation, adds code to emit that

CXXABILowering pass.
In order to handle possible variations in the delete representation, we
add the name of the delete function, the usual delete parameters, and,
optionally, the name of the element destructor function.
During the CXXABILoweringPass, the cir.delete_array operation is
expanded to call the delete function. This will be extended in a future
change to handle reading the array cookie, if required, and calling
element destructors.

[SLP] Loop aware cost model/tree building
Currently, SLP vectorizer do not care about loops and their trip count.
It may lead to inefficient vectorization in some cases. Patch adds loop
nest-aware tree building and cost estimation.
When it comes to tree building, it now checks that tree do not span
across different loop nests. The nodes from other loop nests are
immediate buildvector nodes.
The cost model adds the knowledge about loop trip count. If it is
unknown, the default value is used, controlled by the
-slp-cost-loop-min-trip-count=<value> option. The cost of the vector
nodes in the loop is multiplied by the number of iteration (trip count),
because each vector node will be executed the trip count number of
times. This allows better cost estimation.

When passing options to a pass pipeline that doesn't accept options,
mlir-opt exits with error code 1, but prints no error message when using
shorthand CLI syntax:
```
# Silent failure (no error message):
$ mlir-opt --tosa-to-linalg-pipeline=foo /dev/null
$ echo $?
1
# Same pipeline via --pass-pipeline syntax reports error:
$ mlir-opt --pass-pipeline='builtin.module(tosa-to-linalg-pipeline{foo})' /dev/null
<unknown>:0: error: failed to add `tosa-to-linalg-pipeline` with options `foo`
```
This PR adds replaces the silent call to `failure` with `errorHandler`
in `PassPipelineCLParser::addToPipeline`, matching the existing pattern
in `TextualPipeline::addToPipeline`.

[lldb] Have Host::RunShellCommand ret stderr & stdout seperately (#184548)
Host::RunShellCommand takes a std::string *command_output argument and a
bool hide_stderr=false defaulted argument. If the shell command returns
stderr and stdout text, it is intermixed in the same command_output,
unless hide_stderr=true.
In SymbolLocatorDebugSymbols::DownloadObjectAndSymbolFile we call an
external program to find a binary and dSYM by uuid, and the external
program returns a plist (xml) output. In some cases, it printed a
(harmless) warning message to stderr, and then a complete plist output
to stdout. We attempt to parse the combination of these two streams, and
the parse fails - we don't get the output.
This patch removes hide_stderr and instead adds a `std::string
*separated_error_output` argument. If `separated_error_output` is
nullptr, output and error texts are returned combined in the
`command_output` argument. If a std::string object address is provided
for `separated_error_output`, then standard error output is separated
into this string. A caller which wants the old `hide_stderr=true`
behavior should pass a throwaway std::string object to `RunShellCommand`
and ignore it.

[CIR] Remove diagnostic when handling incomplete record types (#185715)
Following the example of classic codegen, we were checking for
incomplete record types in function signatures and issuing a diagnostic
in a place where it appeared that the type conversion needed to be
delayed. However, because CIR defers ABI processing until after codegen,
we don't actually need special handling for incomplete types.
This change removes the diagnostic and adds a comment explaining the
difference in behavior.

This avoids needing to combine the SHL/SHR/OR pattern later.
This improves code quality on RISC-V where our slx/srx instructions
clobber the destination register but we don't have an immediate form.
We can't recover the original direction from the SHL/SHR/OR pattern
and we can't commute it during the TwoAddressInstruction pass like X86
due to the shift amount being in a register.

This PR introduces `half` type-specific overloads for `mul` and
additional codegen tests for the half type.
Also added f16 tests for the lowering of llvm.matrix.multiply.
The offload test suite already has a `mul.fp16` test for exercising half
types at runtime, so no change is needed there.

[HLSL][DXIL][SPIRV] Added WaveActiveBitOr HLSL intrinsic (#165156)
Adds the WaveActiveBitOr intrinsic from issue #99167. This intrinsic
required a bit more work than the last intrinsics that I have done.
There are some peculiarities, which I verified with dxcompiler:
- WaveActiveBitOr only works on uint and uint64_t, no other types are
allowed
- There is no 16 bit version of WaveActiveBitOr
Followed the checklist:
- [x] Implement WaveActiveBitOr clang builtin,
- [x] Link WaveActiveBitOr clang builtin with hlsl_intrinsics.h
- [x] Add sema checks for WaveActiveBitOr to
CheckHLSLBuiltinFunctionCall in SemaChecking.cpp
- [x] Add codegen for WaveActiveBitOr to EmitHLSLBuiltinExpr in
CGBuiltin.cpp
- [x] Add codegen tests to

[clang][ssaf] Add ssaf-format to validate and convert summaries
This PR introduces the `ssaf-format` command-line tool, which validates
and converts translation-unit (TU) and link-unit (LU) summaries between
registered serialization formats in the SSAF framework. After the
serialization format registry and the JSON format were introduced, there
was no standalone tool to inspect, validate, or convert summary files
outside of a full compilation pipeline. `ssaf-format` fills that gap: it
serves as both a format validator (read without writing) and a format
converter (read then write to a different format or path).

[InstCombine][profcheck] Set unknown branch weights when folding booleans (#185769)
In cases where two logical operations are folded into one, InstCombine
first folds one of the logical operations into an binary operation,
losing the profile information. Ordinarily, we could've used that
information to compute the branch weight information of the new
instruction, but since we don't have the original weights, we say the
new instruction has unknown branch weights.

It doesn't make sense to run these on Windows because this is testing dSYM-specific logic (which hard-codes forward slashes to navigate the dSYM directory). Technically we don't even need it on Linux, but since they pass, keep them on there for now.

[BPF] Fix CORE optimization bug in BPFMISimplifyPatchable (#183446)
Commit ffd57408efd4 ("[BPF] Enable relocation location for
load/store/shifts") enabled CORE relocation for load/store/shirts. In
particular, the commit did optimization to have load/store/shift insn
itself having the relocation. For the load and store, the optimization
has the following:
rX = *(rY + <relocation>) and *(rX + <relocation>) = rY
There is no value-range check for the above '<relocation>'. For example,
if the original `<relocation>` is 0x10006 due to a large struct, the
insn encoding of `<relocaiton>` will be truncated into '6' and incorrect
result will happen.
This patch fixed the issue by checking the value range of
'<relocation>'. If the `<relocation>` is more than INT16_MAX,
optimization will be skipped.
Even llvm side is fixed, libbpf side may still have issues with the
current approach since libbpf may change the value of <relocation>. If
the <relocation> value is more than INT16_MAX, libbpf will either fail
or need to patch insns.
Let us say we have
rX = *(rY + <relocation>) and *(rX + <relocation>) = rY
libbpf will modify `<relocation>` value depending on the actual offset
in kernel data structure. If `<relocation>` is more than INT16_MAX, more
than one insn will be necessary. llvm can add nop instructions for patch
purpose (see [1]).
The following are major patching cases:
case 1: rX = *(rY + <relocation>) // rX and rY are different
rX = <relocation>
rX += rY
rX = *(rX + 0)
case 2: rX = *(rX + <relocation>)
rX += <relocation>
rX = *(rX + 0)
case 3: *(rX + <relocation>) = imm
rX += <relocation>
*(rX + 0) = imm
rX -= <relocation>
case 4: *(rX + <relocation>) = rY // rX and rY are different
rX += <relocation>
*(rX + 0) = rY
rX -= <relocation>
case 5: *(rX + <relocation>) = rX
// We are not able to resolve this issue.
A llvm option (-disable-bpf-core-optimization) is implemented to
disable bpf core optimizaiton, which means the relocation will not
be in load/store insns. This can workaround the above case 5.

[Hexagon] Fix B0 macro conflict between hexagon_types.h and termios.h (#184539)
POSIX termios.h defines `#define B0 0000000` for baud rate 0. This
conflicts with the B0() member functions in hexagon_types.h vector
classes, causing compilation failures when both headers are included.
Use #pragma push_macro/pop_macro to save, undefine, and restore B0
around the class definitions so the header is safe to use alongside
termios.h without losing the macro afterward.

[WebAssembly] Clang support for exception-based lookup paths (#185775)
This commit is an attempt to make progress on WebAssembly/wasi-sdk#565
where with wasi-sdk I'd like to ship a single toolchain which is capable
of building binaries both with C++ exceptions and without. This means
that there can't be a single set of precompiled libraries that are used
because one set of libraries is wrong for the other mode. The support
added here is to use `-fwasm-exceptions` to automatically select a
lookup path in the sysroot. The intention is then that wasi-sdk will
ship both a "eh" set of C++ libraries as well as a "noeh" set of C++
libraries too. Clang will automatically select the correct one based on
compilation flags which means that the final distribution will be able
to build both binaries with exceptions and without.

[WebAssembly] Move __cpp_exception to libunwind (#185770)
The `__cpp_exception` symbol is now defined in libunwind instead of
compiler-rt. This is moved for a few reasons, but the primary reason is
that compiler-rt is linked duplicate-ly into all shared objects meaning
that it's not suitable for define-once symbols such as
`__cpp_exception`. By moving the definition to the user of the symbol,
libunwind itself, that guarantees that the symbol should be defined
exactly once and only when appropriate. A secondary reason for this
movement is that it avoids the need to compile compiler-rt twice: once
with exception and once without, and instead the same build can be used
for both exceptions-and-not.

Log Message:
-----------
Basic,Sema: introduce `__attribute__((__personality__(...)))` (#185225)
This attribute allows specifying a custom personality routine for a
function, overriding the default emitted by Clang. The motivating use
case is the Swift concurrency runtime, where C/C++ runtime functions
need to act as barriers for exception propagation — the custom
personality ensures exceptions do not propagate through these frames
unchecked. More generally, this is useful whenever a language runtime is
implemented in a host language with different EH semantics. LLVM IR
already supports arbitrary personality functions on definitions; this
attribute simply exposes that capability to the C/C++ frontend.

[lldb/test] Add generic test variant infrastructure (#185145)
Add a generic `TestVariant` class and `_expand_test_variants` function
that can be used to create new test variant dimensions (similar to the
existing debug_info variant expansion).
Each TestVariant describes a dimension that multiplies test methods by
different configurations. The infrastructure handles method expansion,
xfail/skip decorator support, and setUp-time configuration.
This also generalizes `_xfailForDebugInfo`/`_skipForDebugInfo` into
`_xfailForVariant`/`_skipForVariant`, and changes the decorator's inner
fn() to accept **kwargs so variant values can be passed by name.
The `_test_variants` list is currently empty — downstream forks (i.e.
swift) can register their own variants without modifying the metaclass
logic.

[DA] Add tests for the Weak Zero SIV tests miss dependency (NFC) (#184998)
Add test cases where the Weak Zero SIV tests miss dependencies due to
the calculation of negative values. SCEV represents the negative value
of `x` as `-1 * x`. When `x` is the signed minimum value, this
expression effectively evaluates to `x`, which causes DA to miss the
dependency. In DA, if we cannot prove that the value is not the signed
minimum when computing the negative value, the analysis should bail out.

[WebAssembly] Remove `__c_longjmp` from compiler-rt (#185798)
This is similar to #185770 where it removes an
exception-handling-related symbol from `compiler-rt` in favor of having
definitions elsewhere. The compiler-rt library is linked into all shared
objects, for example, which can result in duplicate definitions of a
symbol where this tag wants to have one unique definition. The intention
behind this commit is to defer the definition of this symbol to
downstream libraries, such as the definition of `longjmp` itself. An
example of this is WebAssembly/wasi-libc#772 where the responsibility of
defining this symbol now lies with wasi-libc.

Zbc now implies Zbkc so we don't need an Or. I've moved the diagnostic
string from HasStdExtZbcOrZbkc to HasStdExtZbkc to avoid assembler
output changes.
