[Transforms][Utils] Strip unnamed_addr on indirect call promotion (#221121)
This patch strips unnamed_addr from the target symbol and vtable when
call promotion introduces an equality comparison.
When promoting an indirect call site, ICP introduces an equality check
comparing the called value against the target:
if (fp == &callee)
callee();
else
fp();
This address comparison makes the callee's address significant. If the
callee symbol has unnamed_addr, AsmPrinter skips emitting it into the
.llvm_addrsig table. Consequently, the linker (under -icf=safe)
considers the symbol safe to merge with another identical function.
This can happen in practice with AutoFDO if an indirect call site is
profiled against an unrelated function whose machine code was folded by
ICF in the profiled binary. ICP then promotes the indirect call against
that wrong symbol. If the linker folds the symbols again, the equality
check evaluates to true at runtime, directing execution into the wrong
branch.
By stripping unnamed_addr from the callee and vtable address points
during promotion, the symbols are recorded in the .llvm_addrsig table
and
kept unique by the linker, preventing safe ICF from merging them.
Thanks to Arthur Eubanks for the idea of stripping unnamed_addr.

[mlir][complex] Avoid cancellation in tanh denominator (#221014)
In ComplexToStandard lowering of `complex.tanh`, the denominator
expansion includes an exponential term:
$\text{denom} = \text{expm1}(2a) + \text{expm1}(-2a) + 4\cos^2(b)$
When $a$ is small, $\text{expm1}(2a) \approx 2a + 2a^2$ and
$\text{expm1}(-2a) \approx -2a + 2a^2$ have opposite signs. Adding them
cancels the leading $\pm 2a$ terms, resulting in loss of precision.
Near poles ($b \approx \pi/2$), $4\cos^2(b)$ vanishes and this
cancellation
dominates the denominator, causing large relative errors in both real
and imaginary parts.
Since $-(e^{2a} - 1)(e^{-2a} - 1) = e^{2a} + e^{-2a} - 2 =
\text{expm1}(2a) + \text{expm1}(-2a)$,
this term can be evaluated via multiplication instead:
$\text{denom} = -\text{expm1}(2a) \cdot \text{expm1}(-2a) + 4\cos^2(b)$
This eliminates cancellation as $a \to 0$ while reusing the pre-existing
$\text{expm1}(2a)$ and $\text{expm1}(-2a)$ values from the numerator
without
requiring additional transcendental evaluations.

[flang][Semantics] reject COMMON/EQUIVALENCE/derived types whose size does not fit in int64 (#219976)
Semantics was not enforcing the overall byte sizes when of
common block and equivalence storage when building the related symbols
and computing offsets for members. The size and offset silently
overflow, leading to computing inconsistent offsets in lowering and
aborting compilation with internal errors like "error: 'hlfir.declare'
op storage offset exceeds the storage size".
This patch limits the storage of such objects to what can fit a signed
64 bit integer (like gfortran/ifx/classic flang).

[NFC][LowerTypeTests] Add tests for CFI jump table hotness ordering (#221045)
Add pre-commit test coverage establishing the baseline CFI jump table
layout before implementing hotness-based reordering in
https://github.com/llvm/llvm-project/pull/221046:
- cfi-jumptable-hotness.ll: checks jump table entry layout with IR
function attributes (hot/cold) and entry count profile metadata.
- cfi-jumptable-hotness-summary.ll: checks jump table entry layout
with ThinLTO module summary call edge hotness types (using text
summary IR and split-file).
These tests verify the baseline declaration-order layout where functions
within each strict type are placed without hotness consideration, making
the subsequent reordering diff explicit and easy to review.

[C++20] [Modules] Identify the tag redecl through Using (#221147)
Close https://github.com/llvm/llvm-project/issues/96423
We've already have some logics to merge the redecls. But if the previous
decls are found through using decl, we can't merge them right now. As
the reproducer shows. The using decl is common in modules as a common
method to wrap headers into a module.
The fix is simple too. If the existing check fails, we'll check if the
found one is a using decl, if yes, we will reuse the existing check with
the target decl for using decl.

A recurrence's exit value is its closed form Start + BTC * Step. The sum
does not wrap, if the recurrence does not wrap: the recurrence reached
iteration BTC, so the value it computes there is the value the recurrence

The flags are attached to the returned use, because they only apply to

[AArch64][GlobalISel] Add support for shuffle(v, undef) -> trn(v, v) transformation (#220914)
Stacked PR: 3/3. Preceded by
https://github.com/llvm/llvm-project/pull/220535.
In SDAG, the aarch64-isel phase checks if vector shuffles can be
expressed as trns. To do this, it checks shuffles of type shuffle(v, v),
and shuffle(v, undefined).
GlobalISel previously only checked shuffles of type shuffle(v, v). Add a
check for the situation where one of the operands is undefined.
Notes:
A trn takes two vectors, places the even-indexed elements in the bottom
half, and the odd-indexed elements in the top half.
e.g: `trn <0, 1, 2, 3>, <4, 5, 6, 7> => <0, 4, 2, 6, 1, 5, 3, 7>`.
A trn1 takes the bottom half of the result (aka. the even-indexed
elements)
e.g: `trn1 <0, 1, 2, 3>, <4, 5, 6, 7> => <0, 4, 2, 6>`.
A shuffle is a generic MIR opcode that takes 2 vectors, and places
elements of each into a single vector. The elements are selected based
on a mask.
e.g: `G_SHUFFLE_VECTOR <A, B, C, D>, <E, F, G, H>, <0, 4, 6, 3> => <A,
E, G, D>`.
For certain masks, a shuffle can be represented as a trn.
e.g: ```G_SHUFFLE_VECTOR <A, B, C, D>, <A, B, C, D>, <0, 4, 2, 6>
=> trn1 <A, B, C, D>, <A, B, C, D>
=> <A, A, C, C>```.

[VPlan] Don't widen extractvalue with single scalar operand (#221146)
If the struct to extract isn't widened, e.g. because it's fed into an
address computation for an interleave, don't widen the extractvalue. A
single scalar extractvalue can still be executed ok.

[LLVM][NFC] Use +inf/-inf syntax for all floating point infinity literals (#221056)
Follow up to https://github.com/llvm/llvm-project/pull/221019
Replaces all remaining legacy `0x*` (double literal) encodings with the
canonical `+inf` and `-inf` syntax for positive/negative infinity

Compile-time impact is in the noise in almost all cases except lencod
with ThinLTO. On current main, compile-time for the workload regresses
by ~3%, but almost all additional time is spent in SLP: after some
branches got removed and BBs got merged got bigger, and SLP compile-time
scales super-linearly in block size in some cases.
Together with https://github.com/llvm/llvm-project/pull/220968 the
regression goes down to ~+1.18% on the workload. I have 2 more prototype
patches that reduce the overhead by another ~0.30%. I am not sure if the
compile-time issue should block the patch.

[AArch64] Fix vector.match lowering with VLS SVE (#220647)
With `vscale_range()` fixed-vector types > 128-bit can be legal. If
these are used as a `vector.match` needle we still need to split them as
match works per 128-bit segment.
Also, masks such as `v8i1` become legal for types other than i8 and i16,
so we can't assert the source operands are `i8` or `i16`.

[VPlan] Use VPlan-based costs for all integer IVs. (#217766)
Continue the migration of induction costs to be completely VPlan-based.
VPScalarIVStepsRecipe now supports compute its cost for integer
inductions. Skip the legacy precomputeCost code for them.
The main change is that previously we never explicitly accounted for the
canonical IV, which we always generate. It was instead folded into
computing cost of the existing integer IVs with only scalar uses, which
in
most cases are actually served by the canonical IV.
The new code accounts for the cost explicitly, as
VPInstruction::computeCost returns 0 for all recipes w/o underlying
instruction.
Floating point and pointer induction will be handled as follow-ups to
keep the diffs managable and make it easier to track down regressions.
There are a few tests where cost decisions change, but overall they
should be more accurate:
-
llvm/test/Transforms/LoopVectorize/AArch64/conditional-branches-cost.ll:
- partial-reduce-with-invariant-stores.ll
via the legacy cost model, we computed the cost of i64 vector
induction (which has cost of 2/4 for VF 4 and 8), while now we compute

[CodeGen] Add Action types for vector_(de)interleave ops (#220859)
Targets could not set lowering actions with setOperationAction for
Interleave operations due to dependence on type and factor. Instead of
requiring two API to find legality of operation one for type and one for
factor. It is cleaner to add a separate action type for these operation.

[CIR] Give the cleanup kind a proper standalone attribute spelling (#220878)
CleanupKindAttr overrode its assembly format to a bare `$value` so
`cir.cleanup.scope` would print `cleanup all`. The cost was that the
attribute had no readable standalone form, falling back to
`#cir<cleanup_kind all>`.
The `enum($attr)` operation directive removes the tradeoff. The
attribute
keeps CIR_EnumAttr's bracketed default and now spells
`#cir.cleanup<all>`,
while the operations ask for the bare keyword. The mnemonic drops the
`_kind`
suffix the C++ class name carries.

[LV][AArch64] Provide option to use partial reductions by default (#216001)
Partial reduction intrinsics are explicitly unordered, which may allow
us to perform extra optimizations that may result in a different
ordering of lanes within a vector. This would only be done if the target
indicated the intrinsic was at least as cheap as the normal accumulation
operation.
Off by default to start with.
As an example of an optimization which would be easier/less fragile with
this change, see #206047 which currently tries to match the entire
reduction. If the in-loop update was a partial reduction intrinsic (even
at the same VF), then we could just implement the whole thing as a
DAGCombine.
Some follow-up work will be needed before turning on by default; there's
25 AArch64 check-all failures (just need to update test checks) and some
build failures + regressions in some spec benchmarks to look at.

[RuntimeLibcalls] Add stack protector entries for AVR (#220597)
`__stack_chk_fail` used to be part of the default set of runtime libcall
impls. #148789 moved it out of that set and re-added it explicitly to
each target's `SystemRuntimeLibrary`, and #154930 did the same for the
`__stack_chk_guard` global. `AVRSystemLibrary` was not updated by
either, so both `RTLIB::STACKPROTECTOR_CHECK_FAIL` and
`RTLIB::STACK_CHECK_GUARD` are `RTLIB::Unsupported` on AVR.
Lowering a function with `sspreq` therefore fails twice: loading the
canary reports "unable to lower stackguard", and the failure path dies
in `TargetLowering::makeLibCall` with a `reportFatalInternalError`:
```
$ llc -mtriple=avr ssp.ll
error: unable to lower stackguard
LLVM ERROR: unsupported library call operation
```
Add the two impls directly, as Lanai, MSP430 and Hexagon do. This
restores the pre-#148789 codegen, which referenced `__stack_chk_guard`
and `__stack_chk_fail`.

[clang][Parse] Fix DeclContext reentry to use the template's lexical TU, not the current fragment's TU (#218571)
Problem:
when `-fdelayed-template-parsing` is enabled Instantiating a late-parsed
function template defined in an earlier TU caused an assertion failure
in `clang::Sema::PushDeclContext`:
``DC->getLexicalParent() == CurContext && "The next DeclContext should
be lexically contained in the current one."'`
Fix:
- 1 in `Parser::ParseLateTemplatedFuncDef` obtained the enclosing
`TranslationUnitDecl` called it `LexicalTU`
- 2 changed `GlobalSavedContext` with the `LexicalTU` instead of using
`Actions.Context.getTranslationUnitDecl()`
- in the case that no `LexicalTU` was found fellback to
`Actions.Context.getTranslationUnitDecl()`

[CIR][AMDGPU] Add support for AMDGCN cmp and ballot builtins (#198135)
Adds CIRGen for the AMDGCN comparison and ballot builtins:
- __builtin_amdgcn_fcmp
- __builtin_amdgcn_fcmpf
- __builtin_amdgcn_sicmp
- __builtin_amdgcn_sicmpl
- __builtin_amdgcn_uicmp
- __builtin_amdgcn_uicmpl
- __builtin_amdgcn_ballot_w32
- __builtin_amdgcn_ballot_w64
The cmp builtins are deprecated in favor of ballot_w32 and ballot_w64,
but classic CodeGen still supports them, so CIRGen matches it for
parity. The deprecation is a Sema-level warning and does not affect the
emitted IR.
@ranapratap55 Let me know if you would like a comment noting the
deprecation, either in the implementation or the tests.

[clang] Fix lost lambda capture in dependent co_return operand (#220234)
09231ed02384 ("[clang] Delay dependent co_return promise calls") made
Sema::BuildCoreturnStmt return early for a type-dependent operand,
before reaching the ActOnFinishFullExpr() call that every other path
performs.
Inside a lambda, a reference to a variable of an enclosing function is
not captured immediately: DoMarkPotentialCapture() only records it via
LambdaScopeInfo::addPotentialCapture(), and relies on
ActOnFinishFullExpr() to turn it into an actual capture and odr-use.
Skipping that on the dependent path silently drops the pending capture,
so a variable mentioned only in the operand of a dependent co_return
never gets a capture field. When the generic lambda's call operator is
later instantiated from another context, Sema tries to capture the
variable again and rejects valid code with "reference to local variable
'p' declared in enclosing function".
Finish the full-expression on the dependent path as well.

[mlir][arith] Fold scaling_extf and scaling_truncf with constant operands (#215123)
Add constant folders for the two MXFP scaling casts, mirroring the
expansion
in `ExpandOps.cpp`:
```
scaling_extf(in, scale) -> mulf(extf(in), extf(scale))
scaling_truncf(in, scale) -> truncf(in / extf(scale))
```
Note the asymmetry the expansion already has: `scaling_extf` widens the
scale
to the result type, `scaling_truncf` to the type of `in`.
These were the only two ops in the dialect with neither a folder nor a
canonicalizer, so `-canonicalize` left them alone even with both
operands
constant, while `-arith-expand -canonicalize` folded them away.
Pipelines that
lower them to hardware instructions rather than expanding them, such as
`ArithToAMDGPU` and `XeGPUToXeVM`, never got the fold.
As in `arith.extf` and `arith.truncf`, the widening and narrowing steps
go
through `convertFloatValue` and fold only when lossless, so a
`roundingmode`
on `scaling_truncf` never changes a folded result. Poison propagates and
shaped results are guarded with a static-shape check, as in the generic
folders.
Scales that are not already `f8E8M0FNU` are left alone, because what
such a
scale means is unsettled: the tree does not say whether truncating a
wider
scale to `f8E8M0FNU` rounds or takes its exponent, and `ArithToAMDGPU`
passes
it to an instruction that reads only the exponent. #215295 asks for a
ruling.
The input space of these types is small enough to enumerate, so every
combination was checked against `-arith-expand -canonicalize`, against
the OCP
MXFP semantics computed independently of LLVM, and -- for the decision
to fold
or not -- against the losslessness rule above:
| sweep | cases | folded | disagreements |
| :--- | ---: | ---: | ---: |
| `scaling_extf` f4E2M1FN x f8E8M0FNU -> f16 | 4096 | 656 | 0 |
| `scaling_extf` f4E2M1FN x f8E8M0FNU -> f32 | 4096 | 4096 | 0 |
| `scaling_truncf` f16 x f8E8M0FNU -> f4E2M1FN | 16777216 | 33390 | 0 |

[CIR] Add RegionBranchOpInterface unit tests and fix cir.await successors (#220507)
Adds unit tests for the five CIR ops that implement
`RegionBranchOpInterface`
with no coverage today, and fixes a `cir.await` bug the new tests found:
`verifyControlFlowInterfaceConsistency` fails on `cir.await` today,
because the
op and its own terminator disagree. `cir.condition` terminates the ready
region
and reports `{resume, suspend}` when the parent is an await, while
`AwaitOp::getSuccessorRegions` listed all three regions as entry
successors and
reported the parent op as the successor of every region exit.
The corrected edges match what `cir.condition` already reports:
- from the parent, the only entry successor is `ready`
- from `ready`, the successors are `resume` and `suspend`
- from `suspend` or `resume`, the successor is the parent operation

[CIR] Drop lang_address_space's custom parenthesized attribute format (#220880)
CIR_LangAddressSpaceAttr overrode its assembly format to
`(` custom<AddressSpaceValue>($value) `)`. The parentheses defeated the
dialect's `#cir.mnemonic<...>` syntax, so the attribute printed as
`#cir<lang_address_space(offload_global)>`. It now uses the bracketed
CIR_EnumAttr default and spells
`#cir.lang_address_space<offload_global>`.
The `lang_address_space(x)` spelling inside `!cir.ptr` and `cir.global`
is
unaffected, since that goes through MemorySpaceAttrInterface in
CIRTypes.cpp.
The attribute-level pair in CIRAttrs.cpp was only reachable from the
deleted
format, so it goes away.

[VPlan] Extend cse to eliminate redundant widened loads (#212543)
The generic cse() skips memory-reading recipes, so duplicate widened
loads are never eliminated. Extend cse() to also CSE redundant
VPWiden(EVL)LoadRecipes.
Within a VPBasicBlock, loads are matched against earlier ones with the
same address, mask, scalar type and alignment; the candidate list is cleared
on any memory-writing recipe (a conservative aliasing barrier), so load CSE
stays within a single block. This covers consecutive, masked and gather loads.

Log Message:
-----------
[CodeGen] Don't misinterpret a UINT64_MAX-sized stack object as dead (#220172)
Fixes #214750
A static alloca of `0xFFFFFFFFFFFFFFFF` bytes — what clang emits for
`__builtin_alloca(-1)`, which is valid C — crashed with `Assertion
'!isDeadObjectIndex(ObjectIdx) && "Getting frame offset for a dead
object?"' failed`. MachineFrameInfo encoded dead stack objects in-band
as `Size == ~0ULL`, so this object was considered dead from the moment
it was created: PEI skipped it when assigning frame offsets, but the
frame-index reference was still in the function, and eliminateFrameIndex
asserted when resolving it. No pass ever marked the object dead — the
size itself collided with the sentinel. Not actually a recent regression
despite the label; it reproduces back to 20.x, and GlobalISel had the
identical latent bug since it also feeds the raw alloca size into
`CreateStackObject`.
Deadness is now a separate `isDead` flag on `StackObject` instead of
borrowing a size value, so no size can flip an object's liveness.
`RemoveStackObject` sets the flag, `isDeadObjectIndex` reads it, and the
frame-object debug printer — the only other place that looked at the
sentinel — checks it too. This fixes both instruction selectors at once
rather than clamping the size at each call site. An allocation this
large can never succeed at runtime anyway; a size one byte smaller
already compiled fine through the same path, and now `-1` behaves the
same way. Added `llvm/test/CodeGen/X86/pr214750.ll` covering both the
`-O0` and default pipelines with `-verify-machineinstrs`.
LLM tools were used for this contribution. I've reviewed, built, and
tested the change myself before pushing to GitHub.

[InstCombine] Evaluate zext nneg as sext where possible (#212230)
We can convert zext nneg to sext, and doing so when evaluating an

result will be correct without needing to mask them.

nothing ever built or printed the attribute.
Its only consumer was CIRGenModule::getGlobalVisibilityAttrFromDecl,

never called, and that was the only caller of
getGlobalVisibilityKindFromClangVisibility, so all three go together.

as frontends insert a vscale_range attribute that we can use. As such,
this patch is a non-functional cleanup, along with test updates, taking
care to minimize the diff by inserting the vscale_range attribute in
various tests.

[Clang] Clean up leftover old offloading driver tools and utilities (#221093)
Summary:
This PR cleans up some now unused utilities.
1. The old driver fatbinary object building
2. The SDL library linking
3. The offload bundler unbundler job
These are all replaced by operations the new driver does. The one hitch
is that the `--offload-device-only -lfoo -frdc` will not unbundle like
it once did, but I am unsure if that was ever used much in practice.

bitcast`

Each enum now sets genSpecializedAttr = 0 and gains a CIR_EnumAttr
wrapper,
and the operations wrap the argument in `enum()` to keep the bare
keyword,
giving spellings like `#cir.cast<bitcast>`. Mnemonics drop the suffix
the C++
class name carries.

-----------
[lldb][test] Fix flaky results from TestSymStore.py test_http_timeout (#221196)
Fixes #217733.
Observed only on Windows on Arm but I bet it can happen other places.
Sometimes the test would fail because it did not find the error message
in the log file.
The problem is that the test is relying on the client to realise the
timeout has been exceeded and close the connection, before the fake
responder can send back status 200.
So what sometimes happens is:
* The client sends the request.
* The server gets the request and waits N seconds.
* The client is delayed doing other things, and doesn't realise the
timeout has been reached. So the connection is still open.
* The server tries to respond with 200, and that sends succesfully.
* The client wakes up and sees the 200 response, so there's no error to
report.
To fix this, I've changed the responder from merely being slow to never
responding. This means the client can be delayed as long as it likes.
To prevent the responder hanging around, it waits on an event which the
test will set once the test is done (whether pass or fail), then the
responder will shut down normally.
This change does mean that if the client was buggy, we could be waiting
up to the global test timeout. However I think that's a reasonable trade
to not have flaky test results. The alternative is to increase the
responder delay, which will have to vary machine to machine and run to
run. In the end, you'd end up with a delay very similar to the global
test timeout anyway.
This change also narrows the original intent, though not the original
behaviour of the test. We would like to test that the timeout is used,
is accurate, and is configurable. Doing so without flakes is more work
than I'm willing to commit to right now.

[CIR][NFC] Share getSuccessorInputs across region-branch ops (#220509)
All ten CIR ops implementing `RegionBranchOpInterface` hand-wrote
`getSuccessorInputs`, and all ten implementations expressed the same
behavior: regions take no inputs, while returning to the parent yields
the parent’s results.
Three appeared different but were equivalent:
- `CleanupScopeOp` and `CoroBodyOp` unconditionally returned an empty
ValueRange, and neither declares results in ODS.
- `AwaitOp` returned region block arguments, but it carries
`NoRegionArguments`, so those ranges are always empty.
`CIR_RegionBranchOpBase` now declares the method and generates the
shared implementation through extraClassDefinition.

This patch does (hopefully) the infrastructure work to get this running
right.
I asked Claude to help me with the CMake files, and best I can tell it
looks right? But if someone knows better, please let me know. I suspect
we might need to add dependencies along the way as we add new things,
but this seems to work at the moment?
Otherwise, this just moves a handful of trivial utilities that seemed
like a good starting point, plus one I need for CIR right away.

[libc++][pstl] Implementation of parallel std::min_element() based on parallel reduce (#219876)
This PR adds an implementation of parallel `std::min_element()` based on
parallel reduce.
`std::max_element()` is also added, implemented as a "one-liner" over
`min_element`.
The implementation formulates `min_element` as a reduction of iterators
over the input range.
The reduction is provided in two forms: 2-element reduction that picks
the iterator pointing to a smaller value, and a range-based reduction
with init value. The latter delegates the heavy-lifting to the serial
implementation of `std::min_element()`.
Part of #99938.

[X86] Remove TEST after SHL by 1..3 when the shifted operand dies (#220744)
optimizeCompareInstr refuses to reuse the flags of a SHL by 1..3 so that
TwoAddressInstructionPass may still convert the shift into an LEA, which
sets no flags. That conversion exists to avoid a register copy, so it
can only pay off while the shifted operand has further uses; when the
shift is the operand's sole user, the reservation costs a TEST (2-3
bytes and a uop) for nothing. Allow the conversion in that case, as
already done for SHR, SAR, and larger SHL counts.
An x86lint audit of Firefox's libxul.so counted 4,369 redundant TESTs
after immediate shifts, dominated by single-use left shifts by a small
count feeding a compare against zero, e.g. Rust's Layout size checks
(shl $1; test; je). This also composes with dda2c12275e5: 63-bit lowmask
compares shrunken to SHL by 2 now drop their TEST as well.

[flang][FIRToMemRef] Look through zero-offset views to find fir.array_coor (#215402)
`getMemRefInfo` dispatched only on a FIR memref's immediate defining op,
so a fir.declare (or other zero-offset view) wrapping
`fir.array_coor`/indexing `fir.coordinate_of` was treated as an opaque
scalar reference, dropping bounds information and causing incorrect
runtime behavior (e.g. missing array dimensions) after inlining under an
OpenACC kernels loop.
This peeks through zero-offset FortranObjectViewOpInterface views
(fir.declare, ref/box fir.convert, fir.box_addr, fir.volatile_cast,
fir.create_box, unsliced fir.embox/fir.rebox) for a genuine
fir.array_coor/indexing fir.coordinate_of underneath and dispatches
bounds-aware lowering on it.

[RegisterCoalescer] Do not commute def when a partial def implicitly reads it (#220979)
## Problem
Since f44079db22036d0ade2cf3d2e5a24bde5d378efd, instruction selection
can produce partial register writes (e.g. MOV8rm into sub_8bit) that
implicitly read the rest of the 64-bit register. When
removeCopyByCommutingDef commutes the feeding OR to remove a COPY, it
rewrites only explicit operands and then erases the old definition from
the live interval.
The partial write still implicitly reads that value, so
`JoinVals::analyzeValue` asserts on `Instruction is reading nonexistent
value`.
## Fix
Extend the existing reader check from `use_nodbg_operands` to
`reg_nodbg_operands`, and use `readsReg()` to identify operands that
read `AValNo`. Reject the commute when such a reader is also a def, just
as for a tied use, because it cannot be rewritten independently.
This catches partial defs without introducing a separate scan over all
defs.
## Testing
- New MIR regression test crashes on main (RegisterCoalescer.cpp:2885
assertion) and passes with this change.
- No end-to-end .ll test is included: on the latest HEAD the pass
pipeline no longer takes the branch that triggered the original
assertion.

This showed up in a test suite, and is basically just ensuring that our

of the static functions (and the implementation) are near word-for-word
copies of what classic codegen does.
However, there ARE a few parts that are potentially untested(including
strict-vtable-pointers which aren't implemented yet), but the
implementation is put in place, as it is a mechanical copy/paste
implementation.
Note: Claude came up with additional test cases.

[flang][NFC] Add FortranObjectLoadOpInterface for load provenance (#221088)
The definition walk in AliasAnalysis::getSourceImpl already keys the
address half of a descriptor access chain on
FortranObjectViewOpInterface (fir.box_addr, fir.create_box,
fir.convert), but the load step was hardcoded to fir::LoadOp. Any other
operation whose result is a value read from memory therefore terminated
the walk at SourceKind::Unknown, losing the AllocDeref/PointerDeref root
and coarsening alias results for everything reached through the loaded
descriptor.
Add FortranObjectLoadOpInterface as the value-producing dual of
FortranObjectViewOpInterface: a view op forwards an address, a load-like
op yields the value read from one. It declares a single getLoadSource
method reporting the memory reference a result was read from. fir.load
implements it as getMemref(), so this is NFC, and the box-load case in
getSourceImpl now keys on the interface instead of the concrete op.
The interface documents provenance only and makes no purity claim, so an
operation whose result depends on more than the contents of the memory
reference can participate as long as it models those extra dependences
through its memory effects. Consumers must not use the interface to
justify value-based transformations such as CSE or load forwarding.

[clang-format] Parse ObjC generics in block literal return types (#220995)
The unwrapped line parser handled a block literal's return type as a
single identifier or type keyword followed by optional stars. A return
type carrying ObjC generics or a protocol qualifier, such as
`^NSArray<NSString *> *(int x) { ... }` or `^id<Proto>(int x) { ... }`,
was therefore not recognized as a block, and its body was treated as a
function body instead. This collapsed the body like a short function
and, with `RemoveSemicolon: true`, dropped the semicolon terminating the
enclosing statement, producing code that no longer compiles.
Skip a balanced angle-bracket list after the return type before looking
for the parameter list and body.

[NFC] [Clang] [CodeGen] Reduce code duplication when emitting trap calls (#221022)
There are a number of places in codegen where we do this:
```c++
llvm::CallInst *TrapCall = EmitTrapCall(llvm::Intrinsic::trap);
TrapCall->setDoesNotReturn();
TrapCall->setDoesNotThrow();
Builder.CreateUnreachable();
Builder.ClearInsertionPoint();
```
This patch adds a helper that does this and updates `EmitTrapCall()` to
no longer create a new block after emitting the trap call.
One test had to be updated because an unnecessary block was dropped.
Before, we were generating this:
```llvm
dtor.call_delete_after_array_destroy: ; preds = %dtor.vector.cont
call void @llvm.trap() #7
unreachable
6: ; No predecessors!
unreachable
```
The second block here is now no longer present, which caused some
instruction renumbering.

[PseudoProbe] Prevent invalid callsite identities in inline trees (#219079)
Prevent debugless calls in inlined `nodebug` functions from inheriting
the caller's packed pseudo-probe discriminator. Such inheritance aliases
distinct calls onto one probe index and makes the resulting callsite
profile stale. Add a regression test covering the emitted callsite
probe.
Consider:
```
A:
probe #2
call B
B: // nodebug
call C
```
After inlining B into A, LLVM gets:
```
A:
call C
```
Because B has no debug locations, the inliner gives call C the location
of A -> B. That is sensible for debugging: the instruction now appears
at the inlining location.
The problem is that this location also contains pseudo-probe `ID #2`.
That ID identifies the original A -> B callsite. It doesn't mean "code
executing inside A."
Without the fix, call C therefore looks like:
```
call C, debug-location = A's probe #2
```
Later, PseudoProbeInserter sees the packed discriminator and emits a
machine call probe using its encoded function GUID, probe index, and
type.
That creates a false identity:
```
probe (A, #2, DirectCall)
call C
```
But `(A, #2)` describes `A -> B`, not `B -> C`. Samples collected at C
can consequently be attributed to the wrong source callsite and later
appear stale.
The fix retains everything useful while clearing only the
identity-bearing discriminator.
Thus the result is conceptually:
```
call C, debug-location = A's source location,
inline context = preserved,
pseudo-probe identity = none
```
LLVM cannot recover a usable B -> C location here. Because B is nodebug,
it has no DISubprogram, source location, or scope on which to encode its
callsite probe. Synthesizing these would invent debug information and
conflict with nodebug semantics; carrying probe identity independently
would require a broader representation change.
The conservative fix preserves A’s source location, inline context, and
ordinary DWARF base discriminator, while removing the incorrectly
inherited A → B pseudo-probe identity. Having no encoded probe for B → C
is preferable to assigning it a different callsite’s identity.

[CodeGen] Preserve pseudo-probe context when tail merging (#219502)
BranchFolder normally ignores debug locations when deciding whether
machine instructions are identical. That allowed it to merge
`PSEUDO_PROBE `instructions and calls carrying packed pseudo-probe
discriminators even when they came from different inline contexts.
Merging their debug locations then kept only the common outer ancestry,
which moved profile attribution to the wrong callsite.
Keep tail merging enabled, but stop matching at a probe-sensitive
instruction unless both instructions have the same source and inline
context. Call probes also require the same packed discriminator. Tails
from the same probe context remain eligible for merging.
Add MIR coverage for block probes and call probes, including checks that
same-context tails still merge, under both the legacy and new pass
managers.

[lldb][AMDGPU] Support terminal DW_OP_LLVM_piece_end (#220774)
AMDGPU can emit a location expression whose pieces are followed by a
terminal DW_OP_LLVM_piece_end. LLDB already assembles the DW_OP_piece
operands into its single out-of-band composite, but currently rejects
the final LLVM user operation.
Recognize one terminal DW_OP_LLVM_piece_end as a no-op. A non-terminal
occurrence, including the first of multiple piece-end operations,
remains an error. This intentionally does not implement multiple
composite location descriptions.

[Sema] Don't crash filling TypeLoc for a reused AttributedType (#220139)
TypeProcessingState::takeAttrForAttributedType assumed every
AttributedType encountered while filling a declarator's TypeLoc had an
(AttributedType*, Attr*) pair registered earlier in the same
TypeProcessingState's AttrsForTypes.
That assumption doesn't hold when the AttributedType is inherited from
another declarator, for example when __typeof__ reuses a type built for
a different declaration. In that case,
TypeProcessingState::getAttributedType, the function that registers the
pair, is never called.
Return a null Attr* instead of calling llvm_unreachable when no entry is
found. This is the Attr* that AttributedTypeLoc uses for the current
declarator's TypeLoc, and null is right here because the current
declarator never spelled the attribute itself.

[lit] Apply --filter-out to tests expanded from GoogleTest shards
A GoogleTest shard is a single lit test at discovery time, so
`--filter-out` can only match the shard's name and has no way to
deselect individual gtest cases. The cases only get real names once
`post_process_shard_results` expands the shard's JSON output.
Apply the filter there instead: mark expanded subtests whose full name
matches `--filter-out` as EXCLUDED. Record `has_failure_in_shard` before
the filter is applied, so a shard whose only failing cases were filtered
out is still considered accounted for and is not additionally reported as
a failure of the parent shard.
Add a test which filters out the failing and unresolved cases of the
googletest-format inputs and checks that the run reports 2 excluded
and no failures.

[OMPIRBuilder] Keep the target construct's location for the deinit call (#221303)
#217407 gave __kmpc_target_init and __kmpc_target_deinit a debug
location by setting the outlined function's location once, before
generating the target body. The init call is emitted before the body and
keeps it, but the deinit call is emitted after, and by then the body may
have replaced it.
The body callback builds the body with its own IRBuilder, so nothing it
emits can disturb the one createOutlinedFunction() uses for the
epilogue. But a body holding another OpenMP construct, a nested parallel
say, calls OpenMPIRBuilder::createParallel, and that leaves the builder
pointing at the wrong debug location, or at none at all. The deinit call
then silently loses its !dbg again.
The test added with #217407 uses a target region whose body is a single
store. Such a body never calls back into OpenMPIRBuilder, the location
survives, and the gap was not visible.
Re-establish the outlined function's location after the body callback,
before emitting the epilogue. The epilogue belongs to the target
construct rather than to whatever the body emitted last, so this is the
location it should carry, and init and deinit go back to agreeing.
Extends the existing test with a nested parallel, which fails on the
deinit check without this change.

NVPTX: Drop global AllowFPOpFusion read from allowFMA (#221313)
We're near the end of the decade long effort to eliminate the
fast math fields from TargetOptions. This is one of the few
remaining consumers, so remove it. Update incidentally
changed tests by adding contract flags.

[libc] Add CMake formatting utility (#213102)
Added libc/utils/cmake_format.py and libc/utils/cmake_format_test.py to
format LLVM and subproject CMake files according to LLVM-libc formatting
conventions.
The formatter operates in three passes:
* Lexer: Tokenises input using the cmake-language(7) EBNF specification
into typed Token objects with line and column position tracking.
* Dynamic Schema Scanner: Pre-scans repository CMake modules and
function blocks to learn option, single-value, and multi-value keyword
argument schemas from cmake_parse_arguments and set calls.
* Token-Stream Formatter: Applies 2-space control block nesting, keyword
casing, comment buffering, and multi-line list indentation in a single
pass.
The utility supports parallel multi-core execution (-j/--jobs) and
in-place file formatting (-i/--inplace). Added 44 unit tests covering
formatting rules, edge cases, schema scanning, and error diagnostics.

Add a unit test using a `LD_PRELOAD` shim to verify that a null path
reaches the real implementation without crashing the interceptor.

recognize clone suffixes for global variables, so disable unique linkage
suffixes until demanglers can be fixed."
Now LLVM's demangler handles suffixed data symbols today:
$ llvm-cxxfilt _ZL8glob_foo.__uniq.123
glob_foo (.__uniq.123)
So reverting the change.
The asm-label exclusion added is preserved and now applies to variables
too: a static variable with an asm label keeps its label verbatim.

[clang][Sema] Use DenseMap for SpecialMemberCache (NFC) (#221304)
This patch replaces llvm::FoldingSet with llvm::DenseMap for
SpecialMemberCache in Sema.
SpecialMemberCache is fundamentally a key-value cache that maps a class
and qualification flags to a SpecialMemberOverloadResult. The current
implementation is heavy because each entry in FoldingSet requires a
160-byte SpecialMemberOverloadResultEntry on the bump allocator arena.
LookupSpecialMember returns SpecialMemberOverloadResult by value. As
such, there is no need to use the bump allocator for pointer stability.
This patch also removes FastFoldingSetNode as we are removing the last
use.

For addrspace(1) global variables, which lower to wasm globals, they are
directly appended to the
wasm export. For addrspace 0 globals, the address is exported.
It also fixes the behavior of the existing export_name attribute on
functions, implementing correct
merging behavior to handle cases of duplicate or conflicting

[clang][win] Extend scoped enum varargs for the Windows x64 ABI (#221356)
Fixes #220712
Scoped enum values don't undergo default integer promotions, so they
don't naturally get extended to 32-bit integers. However, MSVC appears
to extend scoped enum values, *specifically* when they appear as
variadic arguments, but *not* when the are passed as fixed arguments:
https://godbolt.org/z/oGozjMnEn
I think we should do the same. I think the main upshot here is that
users will be able to `printf("%d\n", my_u8_enum);` without casting to
`int` explicitly. Even if the `va_arg(ap, int)` on the printf side is
*technically* UB, this seems like a sharp corner we really ought to sand
off.
I dug up some references for how we handle this on the SysV side, and it
seems that we do extend there: a71cc1536167f44f542da2857685f01aa29c0e55
Codex decided it was worth plumbing the `IsNamedArg` boolean through the
ARM64EC classification side channel for good measure.

Moving those copies into gpu.func then called replaceAllSymbolUses on

to sort elements within strict types and place the globally hottest
fragment at the end of the jump table, while preserving 100% contiguity
(single range checks without holes) for all type subsets.

[clang][docs] Generate command line reference as Markdown (#220385)
Update the Clang option documentation emitter to generate MyST Markdown
for the generated command-line reference page. I discovered and
preserved a complicated existing Sphinx program-name workaround for
option IDs that collide after punctuation normalization.
The only markup on Options.td is in the DocBrief fields, and those use
very little markup, so those were all migrated by the agent, not
rst2myst. I unindented the multi-line DocBrief bodies, because
indentation has semantics in both markdown (list indentation) and reST.
Tracking issue: #201242
0.1288% pixels differ in the rendered HTML page.

[clang-tidy] Normalize windows line filter paths (#217038)
`git | clang-tidy-diff.py` emits line-filter paths with forward slashes,
while Windows compilation databases use a mix of forwards and backwards
slashes. These paths are then silently rejected (and no report is
emitted).
Reproduce on windows via:
```
git.exe diff -U0 main -- . | python clang-tidy-diff.py -p1 -path .\build"
```
Git will produce a path like:
```
my/source/file.cpp
```
The compilation database has files with entries like this:
```
"file": "C:\\dev\\repo\\my\\source\\file.cpp",
"output": "my\\source\\CMakeFiles\\source.dir\\file.cpp.obj"
```
Clang tidy tries to match these paths, but fails on the slash
comparison.
Do a few things to fix this:
* Normalize filter paths with `llvm::sys::path::convert_to_slash()`
before matching the compilation database. This is a no-op on posix, but
converts windows forward slashes to backwards.
* Normalize `Filter.Name` paths when parsed
* Write a couple more unit tests for windows specific paths that expose
this behavior
* Enable another UNSUPPORTED test for windows clang-tidy-diff (and make
it run in a nested directory to exercise the issue
Fixes https://github.com/llvm/llvm-project/issues/112038.

[clang][DependencyScanning] Add a Clang Driver Option to Enable Dependency Scanning Logging (#211966)
This PR adds a clang driver option to enable dependency scanning
logging. The important implementation detail is that the
`DependencyScanningService` holds a single instance of the logger, and
we need to route the option to the logger per scan. An `enable` method
is added to the logger's API to enable it with thread safety. A second
detail worth calling out is that the option is a driver option, so if a
`cc1` command is passed directly to the scanner, the option will not be
processed.

[flang][OpenACC] Resolve associations before testing declare flags (#221346)
The OpenACC declare flags are set by semantics on a single symbol: the
one resolved in the scope containing the !$acc declare directive. Any
other scope naming the same entity reaches it through an association
symbol, and those symbols carry their own, empty flag sets.
The allocate and deallocate action helpers tested the symbol taken
straight from the ALLOCATE or DEALLOCATE statement. For an allocatable
declared in a host scope and allocated in an internal subprogram the
AccDeclare test
therefore failed, no acc.declare_action attribute was attached, and
ACCDeclareActionConversion had nothing to convert. The emitted recipes
were never called, so the device copy was neither created on allocation
nor deleted on deallocation.
Resolve to the ultimate symbol and pass it on. Forwarding the resolved
symbol is required because the deallocation attach helpers independently
re-test the data clause flags.
This matches the rest of the OpenACC lowering, which already resolves
before reading these flags. Recipe names are unaffected because
mangleName resolves associations itself before mangling.

recomputeLoopBlockSet and rebuildLoopAfterUnswitch reconstruct by hand
with significant complexity, but analyze() cannot replace them: it
allocates a fresh Loop for every header, while ScalarEvolution stores
the loop pointer in every AddRec, the loop analysis manager keys its
cache on it, and the pass manager hands the running pass a `Loop &`.
Add LoopInfoBase::recompute, which reruns the analysis over the current
CFG but refills the loop each header already had.
Block lists now come out in the analysis's canonical order rather than
the original order filtered, renumbering cloned blocks in eight
SimpleLoopUnswitch tests.

[mlir][linalg] Support non-trailing dropped dims when vectorizing rank-reducing `InsertSliceOp` (#219192)
`vectorizeAsInsertSliceOp` inferred a dynamic source dim's vector size
from `resultType.getDimSize(rankDiff + i)`, which only covers the case
where the rank-reducing dims dropped from `resultType` are the leading
ones and `source` maps to the trailing result dims.
Generalize this to the general case, where a dropped unit dim can be

its actual corresponding (non-dropped) result dim.

[CIR] Migrate AssumeBundleKind, AtomicFetchKind and AsmFlavor off IntegerAttr (#220885)
AssumeBundleKind, AtomicFetchKind and AsmFlavor generated IntegerAttr
subclasses with no dialect spelling of their own. Each now sets
genSpecializedAttr = 0 and gains a CIR_EnumAttr wrapper.
Unlike the other CIR operation enums, these three are reached through
hand-written parsers and printers, so they needed checking individually.
cir.atomic.fetch references $binop declaratively and gains an `enum()`
wrapper. The other two need no change, since printAssumeBundle is
already
typed on cir::AssumeBundleKindAttr and InlineAsmOp::print streams the
enum
rather than the attribute.
Operation syntax is unchanged.

Only use the flags, and add missing tests for a missing flag on only
one of the participating instructions. This is a step toward removing
the AllowFPOpFusion field from TargetOptions.

[CIR] Migrate GlobalLinkageKind, CallingConv and SideEffect off IntegerAttr (#220887)
GlobalLinkageKind, CallingConv and SideEffect generated IntegerAttr
subclasses with no dialect spelling of their own. Each now sets
genSpecializedAttr = 0 and gains a CIR_EnumAttr wrapper, and cir.global
wraps
$linkage in `enum()`. GlobalLinkageKind spells `#cir.linkage<internal>`,
dropping both the `global_` prefix and the `_kind` suffix.
cir.func and cir.call print all three by hand, but they stream
stringifyGlobalLinkageKind(getLinkage()) and friends, which take the
enum
rather than the attribute, so those sites are unchanged.
Operation syntax is unchanged.

[X86] LowerCLMUL - improve vXi32 codegen (#221289)
Shuffle combining is struggling to handle the mixture of vector
unrolling, truncations and optimal use of PCLMULQDQ swizzles, this patch
gives us more optimal lowering direct instead of relying on fixup.
Use the PCLMULQDQ lo/hi control immediate to handle anyext i64 element
evaluation - along with shifting the upper elements down to the lowest
bits of the i64 in parallel
Use UNPACK build vector pattern to avoid FPR<->GPR traffic
CLMULH needs to be handled in a future patch, and vXi16 /might/ be worth
handling as well.

[LoongArch][RISCV] Ignore debug uses when merging base offsets (#221117)
## Summary
Debug instructions are currently enumerated as ordinary users by the RISC-V
and LoongArch merge-base-offset passes. A `DBG_VALUE` can therefore veto an
otherwise valid fold and make `-g` add an ordinary address-calculation
instruction.
Use the non-debug instruction iterator for validation and rewriting, and make
affected debug values unavailable before changing the address represented by
the destination register. Also handle the case where the register has no
ordinary users, which becomes possible after debug uses are excluded.
The same change is applied to both targets because their implementations and
failure mode are equivalent.
## Testing
- `ninja check-llvm-codegen-riscv` (2662 tests passed)
- `ninja check-llvm-codegen-loongarch` (949 tests passed)
Fixes #221109

[CodeGen] Use RegisterClassInfo for remaining allocation-order users (#216510)
Greedy already uses RegisterClassInfo for the function-specific
allocation order (reserved registers filtered, CSRs deferred). Remaining
users still walked TRI's raw order or rebuilt RCI themselves.
Uses RCI.getOrder() everywhere that list is needed (PBQP, Hexagon
spill-slot search*, ARM load/store opt, AMDGPU AGPR-copy MFMA rewrite).
Takes the shared analysis when the pass can preserve it; otherwise keep
a
local RCI after freezeReservedRegs().
Hexagon findPhysReg no longer considers reserved registers.
**Note:** Initially had register scavenger use RCI.getOrder() for
function specific scratch reg allocation, but due to test failures and
the extra loops needed as fallbacks to fix this, this change ends up
likely being outside the scope of this PR so I removed it.
**Another note:** \*Hexagon changes removed from this PR, split into

[Scalarizer][DirectX] Teach the Scalarizer to handle integer bitcasts between scalars and vectors. (#221033)
Fixes #219327
For vector-to-scalar bitcasts, combine the scalarized vector elements
using
extensions, shifts, and ORs. This avoids reconstructing an illegal
vector before
bitcasting it to a scalar. In particular, this fixes the `<2 x i16> ->
i32`
bitcast generated while lowering 16-bit vector `countbits`.
Also move the existing `i64 -> <2 x i32>` legalization from the DirectX
legalizer into the generic Scalarizer. The Scalarizer now splits these
values
using shifts and truncations while respecting target endianness.
With both bitcast directions handled by the Scalarizer, remove
`legalizeGetHighLowi64Bytes` from the DirectX legalizer and move
`downcastI64toI32InsertExtractElements` back into the first legalization
stage.
Add generic Scalarizer coverage for both little- and big-endian targets,
and
DirectX regression coverage for the 16-bit `countbits` case.

[DirectX] Refactor DXILDebugInfo into a pass (#220989)
resolves #220323
DXILDebugInfo was structured as a namespace
with its pass chained to run as part of either
the DXILBitcodeWriter or DXILPrettyPrinter passes.
This is wrong and led to us failing expensive checks because
DXILDebugInfo changes IR but the writers are not expected to do so.
The fix was two fold, move the DXILDebugInfo into a pass. Second,
Refactor all the module debug info reader\writer code out of
DXILDebugInfo and into DXILDebugInfoMap which is used by both the
PrettyPrinter and the BitCodeWriter and move that code into the
DXILWriter compilation module since it is only used by the writers.

[AMDGPU] Extend wide VGPR copy expansion to 96-bit copies (#214561)
Extend physical VGPR copy expansion to handle 96-bit copies using one
64-bit move and one 32-bit move when `V_MOV_B64_e32` is available.
The move order accounts for overlapping source and destination
registers. SGPR-to-VGPR copies are also supported, matching the existing
support for copies whose sizes are multiples of 64 bits.
The first commit precommits regression coverage for non-overlapping,
forward-overlapping, and backward-overlapping copies.

Correct two stale claims: RegUnitStates is indexed by register unit, not

than the two its comment described.
Drop a redundant local in reloadAtBegin(), and assert the def operand
that isTiedToNotUndef() documents.

`filterForDialect` lost its last caller in 4957518ef57f (May 2022) and
has been dead since. It is a static file-scope function template, so
`-Wunused-template` flags it and `-Werror` builds fail. Removing it also
orphans the `DialectFilterIterator` alias and the `llvm::Record`
using-declaration, which nothing else references, so this drops all
three.

[VPlan] Preserve branch weights from VPlan0 through to codegen. (#213143)
This patch adds support for carrying through branch weights from the
original scalar loop through VPlan.
The flow is as follows:
1. On the scalar VPlan, we import the branch weights from the existing
IR branches and add them as !prof metadata to VPInstruction terminators
2. The predicator dissolves the control flow and each block will get
executed unconditionally. What remains are predicated recipes, with
their lanes executing with probability relative to the header. Compute
the executing probabilities as sum of probabilities of all incoming
edges.
3. Each masked recipe gets the execution probability attached as custom
!vplan.execution.frequency metadata
4. When creating replicate regions, a predicated recipe is replaced by
explicit control fold. The execution frequency from the recipe is
converted to profile metadata and added to the newly introduced
conditional branch as !prof.
5. During ::execute, !vplan.execution.frequency is ignored
One thing to note is that step 2 duplicates some logic from IR-based
branch probability info, but doing it natively VPlan allows this to work
with CFG introduced by VPlan itself.
This is an alternative to
https://github.com/llvm/llvm-project/pull/209309, which carried to
branch weights on VPBasicBlocks. This worked somewhat by accident for
replicate recipes: the predicator updates the CFG so all blocks execute
unconditionally, but preserved the execution probability. This is
incorrect at the VPlan level: the blocks execute unconditionally after
predication. It worked for the current use cases because replicate
regions are created before blocks are merged into their predecessors,
but is fragile and inaccurate. Carrying it explicitly across the
conditionally executed entities seems more accurate.
The new approach should work well with also carrying estimated BFI
in the same way, we just need to distinguish between real branch weigths
(which we carry through to codegen, and estimated weights, which don't
carry through to codegen).
And using the info for scalar cost computations on VPlan.

[X86] Lower i64 vector division and remainder through float division (#215043)
Follow up to #205263 which handled i8/i16/i32.
i64 needs a different algorithm because f64 cannot hold a 64 bit
quotient exactly. Instead of one divide the quotient is built from a
reciprocal and two rounded down multiplies plus a correction for the off
by one (https://sneller.ai/blog/avx512-int-div/). That needs the
directed rounding forms which only exist as 512 bit AVX512DQ
instructions, so the whole i64 path is gated on DQ and 512 bit types
being legal.
Operands that are provably narrow enough to fit the f64 mantissa skip
the chain entirely and take the same convert divide convert path as the
<=i32 case.
strictfp i64 uses the SAE forms the same way the <=i32 path does.
combineIntDivRem is now a small dispatcher over two helpers since the
two algorithms share only the setup. combineIntDivRemViaExactFPDiv is
the existing convert divide convert path and
combineIntDivRemViaFPReciprocal is the new chain.
Closes #214939

[IndVarSimplify] Batch forgetValue calls in sinkUnusedInvariants (#219025)
It looks like every `forgetValue` clears the cached SCEV for an
instruction and everything downstream of it, by walking its def-use
children in `visitAndClearUsers` / `PushDefUseChildren` with a fresh
`Visited` each call. Since `sinkUnusedInvariants` calls `forgetValue`
once per sunk instruction, the overlapping users get re-walked over and
over, so it ends up $O(n^2)$.
```cpp
void ScalarEvolution::forgetValue(Value *V) {
SmallPtrSet<Instruction *, 8> Visited;
visitAndClearUsers(Worklist, Visited, ToForget);
...
}
// visitAndClearUsers
while (!Worklist.empty()) {
Instruction *I = Worklist.pop_back_val();
...
ValueExprMap ... erase ...
PushDefUseChildren(I, Worklist, Visited);
}
// PushDefUseChildren
for (User *U : I->users()) {
auto *UserInsn = cast<Instruction>(U);
if (Visited.insert(UserInsn).second)
Worklist.push_back(UserInsn);
}
```
Collecting the sunk instructions and clearing them in one batched call
fixes the issue.

Switch to UniquingSet to remove FoldingSetNodeID serialization overhead
on every AttributeSet::get and AttributeList::get.
Attribute and AttributeSet are single-pointer wrappers whose operator==
is pointer equality. Specializing `is_hashable_data` selects the fast
`hash_combine_range_impl` overload that calls `combine_bytes` directly,
skipping copying element by element.
`hash_combine_range` deduces its element type as `const T`, so
`is_hashable_data<const T>` now follows `is_hashable_data<T>` and a type
need only specialize the unqualified form.

an artifact of the ARM64 and AArch64 merge.
fp-contract.cu is essentially a bugfix, the local fp contract(on) pragma
wins over the global flag now.

[orc-rt] Split support sources into their own object library (#221442)
This allows support to be used by both bedrock and the upcoming SPIRE
library. Note that support is a CMake object library only, not an
archive or dylib. Clients will always target either Bedrock or SPIRE.
Moves some sources (Error, RTTI, Logging, Environment and the whole sys/
tree), and some headers (Environment.h, and the orc-rt/bedrock/sys
headers) to the support library.
The per-system source composition moves to lib/support/CMakeLists.txt.
An upcomming commit will update the unit tests to reflect this split.

[InstCombine] Fold scalbn libcalls to llvm.ldexp (#216573)
This canonicalizes `scalbn`, `scalbnf`, and `scalbnl` libcalls to the
`llvm.ldexp` intrinsic when the call does not access memory.
LLVM floating-point types use radix 2, so `scalbn(x, n)` and `ldexp(x,
n)` produce the same numeric result.
Calls that may access memory are left unchanged because the libcall may
set `errno`, while `llvm.ldexp` does not access memory.

Add a 3-argument set_subtract(A, B, Removed) that computes A := A - B
and records elements of B removed from A (A ^ B) in Removed. When
A.size() < B.size(), B supports contains(), and A supports remove_if(),
we iterate over A via remove_if() instead of iterating over B, improving
efficiency.
Remove the legacy 4-argument set_subtract(A, B, Removed, Remaining),
which was only used by MemProfContextDisambiguation.cpp and is now
redundant since Remaining can be updated via a separate 2-argument
set_subtract.
Update MemProfContextDisambiguation to use the 3-argument set_subtract,
and update SetOperations unit tests.

This change implements `PromotableRegionOpInterface` for `AffineForOp`,

[OptTable] Store Info strings in the string table (#218845)
Change HelpText, MetaVar, AliasArgs, and Values from `const char *` to
StringTable::offset, making the fields smaller, and removing dynamic
relocations in .data.rel.ro in PIC links.
Store them as StringTable::Offset, like the option names already are,
and return StringRef from getOptionHelpText() and getOptionMetaVar().
The 53 tables in the tree lose all 616 KB of .data.rel.ro, and sizeof(Info)
drops from 88 to 60; clang's table becomes 232 KB of .rodata.
An unset field and one explicitly set to the empty string, such as a
HelpText<"">, have to stay distinguishable, so the latter gets an empty
string of its own rather than offset zero.
Values declared with ValuesCode are only known to the generated code,
which supplies getOptionValuesCode() for OptTable to call; only clang has any.

Add a test that the access, free and malloc traces each name the whole

does when
the fast unwinder runs on a target that chains no frames -- fails it.
`deep_stack_uaf.cpp` already covers trace depth, but it looks for three
individual frames anywhere in the trace, so it passes on a trace with
holes in
it, and it needs C++ name demangling to do that.
Split out of #220231 at reviewer request.

[flang-rt] Initialize I/O unit storage read by short-circuit predicates (#221126)
ConnectionState and OpenFile hold common::optional members read through
predicates of the form `opt && x < *opt`, which never use an indeterminate
value in the abstract machine. Compilers do, however, routinely if-convert
the short-circuit && into a branchless compare and select, which speculates
the payload load; because these objects are placement-new'd into malloc'd
storage by UnitMap::Create(), a memory checker then reports a conditional
branch that depends on uninitialized memory. On AArch64 this fires for
every Fortran program that writes a record, giving two reports in
ExternalFileUnit::AdvanceRecord() from IsAfterEndfile() and IsAtEOF(),
while x86-64 is unaffected and libgfortran is clean on the same program and
host. The reports are false positives -- the engaged flag is 0, so both arms
of the select are 0 -- but they are unavoidable noise for anyone running
Valgrind on Fortran code.
Add common::ResetWithDefinedPayload(), which leaves an optional disengaged
while writing its payload storage, and call it at construction for the
optionals in ConnectionAttributes, ConnectionState and OpenFile. Also
initialize OpenFile::pathLength_, which is read through the same
if-convertible shape by the unit-lookup-by-path scans in external-unit.cpp
and unit-map.cpp. No observable behavior changes.
No test is added: the difference is in shadow-memory definedness, which
neither a LIT test nor a flang-rt unit test can observe, and there is no MSan
or Valgrind CI for flang-rt. Verified by compiling the patched headers into a
standalone probe on AArch64, where the unpatched headers give two reports
and the patched headers give none with identical program output, and by
check-flang-rt.

Revert "[DebugInfo] Ignore undefined constexpr constructors in constructor homing." (#221566)
This reverts commit
https://github.com/llvm/llvm-project/commit/6ba0802b406e0963720a698702b9136578dde149
(https://github.com/llvm/llvm-project/pull/218165).
canUseCtorHoming() used to bail out on
hasConstexprNonCopyMoveConstructor().
That commit narrowed the exemption to *defined* constexpr constructors,
on the
assumption that a constructor which is not defined here will be defined
- and
will therefore emit the type's debug info - in whichever translation
unit
constructs the object.
That assumption does not hold when the constructor is never invoked at
all. A
constructor of a class template specialization is only instantiated, and
hence
only defined, where it is used. If nothing ever constructs the
specialization,
its constructors are defined in no translation unit, and so nothing
anywhere
homes the type - even though the type still has to be complete in order
to read
a member.
(The reverted commit's stated rationale, that "declared constexpr
constructors
are not callable in a TU that doesn't see their definition", does not
hold
either: such a constructor can be called outside a constant expression,
with
the definition supplied by another translation unit, and clang emits an
ordinary external call for it. But that is not what breaks here.)
Unions of layout-compatible types are where this bites. The common
initial
sequence rule ([class.mem.general]p26, 9.2/19 in C++11) lets a program
write
through one union member and read through another where the two share a
common
initial sequence, and absl::container_internal::map_slot_type is built
on it:
it aliases std::pair<const K, V> and std::pair<K, V> so that
flat_hash_map<K, V> can hand out pair<const K, V> references while still
moving
keys efficiently. Slots are created and destroyed through the mutable
pair and
only read through the const-key one, so a std::pair<const K, V> is never
constructed, none of its constructors is ever instantiated, and its type
is
emitted nowhere.
Reduced, and linkable - the following compiles, links and returns 0:
template <class A, class B> struct mypair {
A first;
B second;
constexpr mypair() : first(), second() {}
constexpr mypair(const A& a, const B& b) : first(a), second(b) {}
};
template <class K, class V>
union map_slot_type {
map_slot_type() {}
~map_slot_type() {}
using value_type = mypair<const K, V>; // read, never constructed
using mutable_value_type = mypair<K, V>; // constructed
value_type value;
mutable_value_type mutable_value;
K key;
};
map_slot_type<unsigned long, void*> slot;
int marker;
int main() {
slot.mutable_value = mypair<unsigned long, void*>(42, &marker);
return (slot.value.first == 42 && slot.value.second == &marker) ? 0 : 1;
}
mypair<unsigned long, void*> is constructed and keeps its debug info.
mypair<const unsigned long, void*> is only read, and is emitted as a
declaration in every translation unit, so a debugger cannot show first
and
second:
clang 22.1.8 DW_AT_byte_size (0x10)
clang 24.0.0git DW_AT_declaration (true)
This is how it was found - gdb reporting "<incomplete type>" for
std::pair<const size_t, ...> in ScyllaDB, which broke the flat_hash_map
readers
in its gdb scripts.
Keep the test coverage the reverted commit added for the cases whose
expected
output is unchanged, restore the DeclaredConstexpr expectation to full
debug
info, and add the aliased-pair case above.

[ValueTracking] Infer implied conditions through masked bit tests (#219626)
Fixes #214397
`isImpliedCondICmps` failed when one compare constrains X and the other
tests a value derived from X. For example:
`X u<13` implies `(X & 16) == 0`
This adds an additional check. When both compares have constant RHS
operands and the second compare's LHS is `and (L0, C)`, following
strategy is applied: L0's range is derived from the first compare and
the mask is applied. If the resulting range satisfies the second
predicate for all values, the implication is correct. If the inverse
predicate is satisfied for all values, the implication is false.
Otherwise the result is unknown.

[LAA] Fix inverted bounds for negative-step AddRecs with unknown end. (#218388)
Currently we use an conservative upper bound (-1) for runtime checks
when evaluating the AddRec may wrap.
This does not properly account for negative steps. In that case, we need
to use null as conservative lower bound.
One complication is that the null pointer may not be zero, so we need to
check for that, and bail out completely if that's the case. We then must
clean up any pointers partially added.

[MachineOutliner] Properly handle Debug MachineInstrs (#219326)
Fixes #219176.
Debug instructions could affect `MachineOutliner` output in two ways:
- The minimum basic-block size check used `MachineBasicBlock::size()`,
which includes debug instructions. A block containing one ordinary
instruction and one debug instruction could therefore enter the mapper
even though it was too small to outline.
- Mapping an invisible debug instruction cleared `AddedIllegalLastTime`.
This changed the separator state and could affect persistent token
numbering, outlined-function ordering, and ultimately the generated
object code.
This patch makes debug instructions transparent to both decisions:
- Use the non-debug instruction count for the minimum block-size check.
- Preserve the mapper's separator state for debug instructions while
retaining the existing behavior for other invisible pseudos.
The patch adds MIR coverage for both cases and updates the existing
mapper statistics test to reflect blocks that are now skipped.
Testing:
- The original reproducer produces identical ordinary MIR before and
after the outliner for `-g0` and `-g`.
- The normalized machine-code fingerprints for the original reproducer
are identical with and without debug information.
- The complete AArch64 and RISC-V CodeGen test directories pass: 6852
passed, 5 expectedly failed, 0 failed.
AI assistance disclosure: OpenAI Codex 5.6 Sol assisted with the
implementation and testing. The changes were co-reviewed by Claude and

[orc-rt] Split unit tests into SupportTests and BedrockTests (#221562)
Replace CoreTests with one test binary per layer. SupportTests links the
Support object library and nothing else, so a new support-to-bedrock
dependency fails to link rather than going unnoticed.
Making that work required splitting CommonTestUtils.h: its
Bedrock-dependent helpers move to a new BedrockTestUtils.h, so that no
SupportTests translation unit includes a Bedrock header. That in turn
lets ProxyTest join SupportTests -- Proxy.h only forward-declares
Session, so the test can define its own instead of constructing a real
one.

[libc++] Implement LWG4072: std::optional comparisons: constrain harder (#209968)
Resolves #118345.
Previously, the heterogeneous comparison operators (`==`, `!=`, `<`,
`<=`, `>`, `>=`) for arguments `T` and `U` don't check that `T` or `U`
are not a `std::optional` themselves. This allowed the operators to
cause ambiguous overload resolution instead of falling back to
`optional`'s own operators, which possibly caused hard error when there
should not be a matched overload.
This patch implements the resolution by adding
`!__is_std_optional_v<_Up>` (and the `_Tp` equivalent for the reversed)
to the constraints in all twelve involved operators.
As required by the LLVM Project's AI use policy:

[RISCV] Andes: model fast unaligned accesses for the 45-series (#221166)
The 45-series cores support unaligned scalar accesses. Add
FeatureUnalignedScalarMem to each 45-series processor (andes-n45,
andes-nx45, andes-a45, andes-ax45 and andes-ax45mpv), so that it is
selected by -mcpu rather than -mtune. Other processors declare it this
way too. The feature is somewhat architectural: -mtune is only supposed
to affect performance, but reaching it through tune features lets -mtune
introduce unaligned accesses that crash on a CPU which does not support
them.
Cover this in memcpy.ll using -mcpu=andes-a45/-mcpu=andes-ax45. The new
RUN lines pass -mtune=rocket so that the 45-series scheduling model does
not reorder the output, letting them reuse the existing check lines.

[CIR] Convert i1 intrinsic results for bool-returning builtins (#220576)
A target builtin with no special case is emitted through the generic
intrinsic path, which returns the intrinsic's own result type. For a
builtin declared to return bool that type is i1, which CIR models as
!cir.int<u, 1> rather than !cir.bool. cir.if accepts only !cir.bool, so
CIR builtin handling needs to convert i1 results to !cir.bool when used
in this context.
This is verified using __builtin_amdgcn_is_shared.

on z. That is only valid when z is a VGPR. When z is an immediate (e.g.
0x3c00), EXTRACT_SUBREG hi16 does not isolate the high 16 bits, so the
whole constant is ORed into hi: we get (hi | 0x3c00) << 16 instead of hi
<< 16.
Select v_lshl_or_b32 instead, with z as VSrc_b32, matching the fake16

[VPlan] Fix merged replicate region frequency when only one is known. (#221607)
When merging two replicate regions guarded by the same mask, the merged
region's entry frequency should be the higher of the two original
frequencies, since it now fires whenever either original region did.
The existing check only updated the frequency when both were known,
leaving the second region's own (possibly much lower) frequency in place
whenever the first was unknown. This means we might set a misleadingly
low frequency. Conservatively set to unknown instead.

[gold] Switch section-ordering-file tests to use ld.bfd (#219150)
ld.bfd supports `--section-ordering-file` since 2.43. Use it if the
binutils version is sufficiently recent.
The implementation in ld.bfd is significantly different, with the
section ordering file looking more like an incomplete linker script,
rather than a plain section listing.
The addresses of the sections are also slightly different than with
ld.gold. Use hex matches + arithmetic to just check the correct
order/offsets instead of hardcoding the exact choice of address.
ld.bfd also supports --start-lib/--end-lib since 2.47, but it seems like
those don't actually work with linker plugins, so I'm not migrating them
(https://sourceware.org/bugzilla/show_bug.cgi?id=34572).

[InstSimplify] Don't fold ptrtoint of ptradd of sub (#221188)
Don't fold `ptrtoint (ptradd (Ptr, X - ptrtoint(Ptr))) -> X`. While
valid by itself, the fact that LLVM currently does not properly model
the ptrtoint side effect means that we lose the provenance exposure of
Ptr. This results in end-to-end miscompiles that led to the revert of
#210729.
We can still perform the optimization for ptrtoaddr, which does not
expose provenance.

successor is the header), we can still use the IV based condition to

For now, just peels a single AND/OR.

[CIR] Migrate the FPClassTest bit enum and unquote its flags (#220888)
cir.is_fp_class printed its flags inconsistently. Single-bit values came
out
bare, as in `fcSNan`, while group values and combinations came out
quoted, as
in `"fcInf"` and `"fcSNan|fcNegInf"`. That comes from I32BitEnumAttr
setting
printBitEnumQuoted, which EnumAttr.td keeps only for backwards
compatibility.
Clearing the bit and using the `enum` directive selects the
separator-aware
parser and printer, so every value now spells unquoted:
cir.is_fp_class %x, fcSNan|fcNegInf : (!cir.float) -> !cir.bool
The enum also drops its specialized IntegerAttr for a CIR_EnumAttr
wrapper,
giving it the standalone spelling `#cir.fp_class<fcSNan|fcNegInf>`.

bitwise rotate and the shift amount is a multiple of the bitwidth of the
value being rotated. This commit makes this change.

In this patch, we updated clang-scan-deps to report the dependencies
between consumers and the corresponding module described in module map
file in P1689 format. The P1689 format in clang-scan-deps is the defacto
dependency description between compiler and build tools. This helps end
users to use the trick without waiting for the support from various
build tools.

[LoopSafetyInfo] Store Loop and automatically compute (NFC) (#221238)

* LoopSafetyInfo is bound to a single loop. Store the Loop in the ctor,
so it does not need to be passed to individual queries.
* Automatically compute LoopSafetyInfo on construction, instead of in a
separate call. This is mostly to clarify that (contrary to the doc
comment) nobody is actually trying to invalidate LoopSafetyInfo by
rerunning computeLoopSafetyInfo().
This makes it easier to change implementation details, like computing
information lazily.

Derive the CIR bases from `I32Enum`, `I64Enum` and `I32BitEnum`, and
widen
`CIR_EnumAttr` to the `EnumInfo` that upstream `EnumAttr` already takes.
The
flag no longer exists to clear. `FPClassTestEnum` gets unquoted printing
from
`BitEnumBase` rather than overriding `printBitEnumQuoted`, and
`CIR_KnownFuncKind` drops a `parameterPrinter` the generated
`operator<<`
now covers, still spelling `#cir.func_identity<"std::find">`.

Log Message:
-----------
[X86] Don't fold loads from non-fixed stack objects into tail calls (#221243)
Fixes #216504
The callee of a tail call can be folded into the jump as a memory
operand (`TCRETURNmi64`). That jump runs after the epilogue, so the
operand is resolved relative to the incoming stack pointer, which only
works for fixed objects such as incoming arguments. Here the callee was
a `volatile` local, so the load stayed on the stack and got folded,
while a variable-index extract from a 256-bit vector went through a
32-byte stack temporary and forced dynamic realignment. Once the stack
is realigned a local has no static offset from the incoming stack
pointer, and PEI tripped the assertion. The sibcall eligibility check
does look at realignment, but it runs before legalization, so it never
saw the temporary. Spill slots created during register allocation can
cause the same thing, so no check at that point can be complete.
The fold is now refused whenever the load's address may use a non-fixed
frame index, in `checkTCRetEnoughRegs`, which gates both the
`TCRETURNmi` patterns and the callee-load hoisting in
`PreprocessISelDAG`. The callee is loaded into a register before the
epilogue and the call is still emitted as a tail call. Loads from fixed
objects fold as before. As a side effect this also stops the jump from
reading a slot below the restored stack pointer, which was only safe
inside the red zone.

Found while profiling clang compiling `SLPVectorizer.cpp`.
The call chain `DILocation::get` -> `DILocation::getImpl` ->
`llvm::getUniqued` caused lots of expensive `DenseSet` `find_as` and
`grow` operations due to the cache being really inefficient. Switch to
`DILocation::getDistinct` and cache `inlineDebugLoc` by `OrigDL` for a
more efficient cache.

[Flang][NFCI] Use abstraction for binary scalar data (#212956)
There is currently the assumption that the binary representation of the
scalar data classes (Integer, Real, Complex, Logical) is identical to
the binary representation of native types. For instance `Integer<64>`
can be reinterpret-casted to a `int64_t` or serialized using `memcpy`.
This will not be the case anymore with #206907. This first PR introduces
`LoadRawBytes` and `StoreRawBytes` abstractions that can be adapted when
the binary data layout of the scalar data classes change. No functional
change intended.
The binary representation is assumed for these uses:
1. Data serialization in initial-image.h/.cpp
2. Calling native math functions to constant-fold functions such as
`sin` in intrinsics-library.cpp. An abstraction layer has been created
in host.h/host.cpp to convert between host-native types and the scalar
data classes.
Some implementation notes:
* I originally used `CharacterUtils` but it is in a private header file.
Instead I created `CharacterValue` which similar to what #216960 will
introduce to allow a consistent interface between the scalar value
classes (such as `kind()` returning the current runtime kind)
* `bytesStored` is another such common interface. It it meant to
resemble `llvm::DataLayout::getTypeStoreSize` (there is also
`getTypeAllocSize`, `llvm::Type::getPrimitiveSizeInBits()`,
`llvm::Type::getScalarSizeInBits()`) and must match
`common::TypeSizeInBytes`.
* `Real<10>` uses 16-byte alignment regardless what the host compiler
thinks what `long double` should be. The padding is unitialized data in
`X87IntegerContainer`. Even though x87 is the classic example where
"allocation size" and "store size" would be different, Flang does not
differentiate between them and treats all bytes also as stored bytes,
see `common::TypeSizeInBytes`. As a consequence, `Complex<10>` is 32
bytes. initial-image.h/.cpp will even load/store/compare that
uninitialized data. host.h/host.cpp instead reads/writes the floats
separately to translate to whatever the host compiler does.
* initial-image.cpp/.h is inconsistent when it uses number of bytes and
when it uses number of characters
* For the case the image does not have sufficient bytes to read, I did
not want to insert checks whether another byte can be read into every
ReadRawBytes function, and instead add zero-padding explicitly when
necessary.

[clang][NVPTX][MLIR][NVVM] Add overloaded fadd intrinsics (#221681)
This change adds the following overloaded `fadd` intrinsics with
NVPTX codegen:
- `llvm.nvvm.fadd`
- `llvm.nvvm.fadd.ftz`
- `llvm.nvvm.fadd.sat`
- `llvm.nvvm.fadd.ftz.sat`
The rounding mode is passed in as an `i32` immediate operand.
Auto-upgrades the older non-overloaded intrinsics to the new
ones, and updates clang builtins, CIR codegen, and MLIR NVVM ops
to lower to the new intrinsics.
In the interest of completion, this also:
- Adds intrinsics support for lowering some half-precision additions
that were omitted earlier (`f16/f16x2` without saturation, and
`bf16/bf16x2` additions), and support for the `f32x2` type.
- Extends the DAG combine pattern for lowering `fneg + add-intrinsic`
to `sub` instructions to all supported types.
- Adds tests for constant folding of these intrinsics with the newly
supported scalar types.

These properties are stored in `LifetimeSafetyOpts`, which are then
checked inside the `Checker` to avoid invoking expensive reporting
functions mapping to diagnostics that are disabled.
`reportMisplacedLifetimebound` was found to be the most expensive
(possibly because it iterates on redecls).

[SLP]Flatten fsub/fneg chains into fadd reductions with per-operand signs
For unordered fadd reductions, reassociable (reassoc+nsz) fsub/fneg
chain links are recursed into and their leaves tracked with a flipped
sign, which is part of the grouping key, so reduced-values groups are
sign-uniform by construction. If per-value signs cannot model the
chain, the analysis restarts once without the flattening. Negated
parts are combined with vector fsub (may form per-lane fma) and
subtracted once in the final combine; no extra negations are emitted.

[lldb][test] Bump utility expression timeout to 10 minutes (#221691)
LLDB needs to sometimes run utility expressions such as loading
libraries via a call to `dlopen`. These utility expressions have a
timeout associated with them which is only 15 seconds (and 60 on
sanitized builds).
I suspect our expressions reaching this timeout is the reason why
TestLoadUsingPaths.py sometimes fails to load libraries and produces
this error:
```
File "../TestLoadUsingPaths.py", line 78, in test_load_using_paths
self.assertNotEqual(token, lldb.LLDB_INVALID_IMAGE_TOKEN, "Got a valid token")
```
This patch bumps the timeout to 10 minutes. There is no good reason why
this timeout should exist in the first place on test bots, and maybe we
should remove them or make them fatal errors on the test bots. But for
now this patch should at least fix the test randomly failing on very
slow bots.

[lldb][test] Merge demangling tests into one test (#221214)
The XML test report that LIT generates describes the outcome of every
test in the test suite. Currently, the test report for the LLDB unit
tests alone is about 5MiB of which 4.7MiB (about 94%) are used to
describe all 30'000 DemanglingInfoCorrectnessTest instances names (they
don't have any output on success, so this is just used to describe the
test names).
This patch merges all these test instances into one. To make test
failures still easy to parse, this patch changes test function to use a
gtest scrope (which annotates failures with the mangled name) and use
non-fatal checks to continue testing when one test fails.
This reduces the test report size overhead of these tests from 4.7MiB to
about 100B.

[Clang][Driver] Final phase also determined by input (#218802)
Before this PR, `getFinalPhase` assumed that when no option is give then
the final phase will a linking step. This is objectively wrong: For
instance passing a header file as input (`-x c-header` or `-x
c++-header`) triggers precompilation, not linking. Other inputs that do
not have a link phase as specified by `Types.def`
are `.dxo`, `.ifs`, and `.hlsl` files.
Instead of defaulting to link in the absence of any action flag, this PR
uses the last phase that `Types.def` specifies for the given input
files. The effect of this is relevant when handling linking options
which are categorized as "input" like any other file.
Usually these should be filtered out if
there is no linking step. But, since `getFinalPhase` says there is a
linking flag, those are forwarded to the precompile handling which gets
confused with such "inputs". An accurate determination of the final
phase filters out those non-applicable linker options.
Note that the second condition of
`clang::diag::warn_drv_input_file_unused` was inverted: It would print
> clang: warning: -lfoo: 'linker' input unused when '' is present
[-Wunused-command-line-argument]
when passing a linker option to a non-link command that is not the
result of an action command flag. Inversely, when a non-link action flag
was used, it wasn't mentioned in the diagnostic message.

depends on that in a number of places, either by naming an insertion
point directly or by handing `Builder.saveIP()` to an entry point that
takes a `LocationDescription`.
Spell out what each of those sites means instead. Where a live builder
is already sitting at the insertion point it is passed directly, and
where the test names an insertion point of its own the empty location is
written out, which is what it was getting before, so no test changes
behavior.

[X86] Fix eliminateFrameIndex dropping existing index register for huge frame offsets
When the frame offset does not fit in disp32 and the address mode already
uses an index register, the register-scavenging path overwrote the index
operand with the scratch register, silently dropping the index from the
effective address (and applying the stale scale to the frame offset).
Fold the offset into the base register with an LEA in this case instead.
Fixes #213960

[CIR] Drop dead ceremony around the CIR enum attributes (#220890)
Five things that no longer earn their place in the CIR enum attribute
machinery.
CIR_CleanupKindAttr carried three. Its cppClassName restated the default
AttrDef already derives. Its skipDefaultBuilders plus hand-written
AttrBuilder existed only to default $value to CleanupKind::All, which no
caller relies on, so the generated builders stayed suppressed for
nothing.
And its summary and description restated the name, overriding the enum's
own
"cleanup kind" that EnumAttr would otherwise inherit. The isNormal, isEH
and
isNormalAndEH helpers stay.
CIR_TLSModelAttr's summary restated its name the same way, so only that
goes.
CIR_DefaultValuedEnumParameter has never had a user.

Included unit tests in swap_test.cpp and algorithm_test.cpp.
Adopted the new utilities in initial callsites:
* stdlib: Used cpp::swap in qsort_data.h
* wctype: Used cpp::swap in perfect_hash_map.h
* math: Used cpp::clamp in powf.h
* scanf_core: Used cpp::min and cpp::max in parser.h
Also fixed sign extension when parsing scanset specifiers in parser.h:
signed characters greater than or equal to 128 produced negative values,
inverting comparisons and causing out-of-bounds writes in the bitset.
Scanset characters are now cast through uint8_t, and non-ASCII tests
were added to parser_test.cpp.

[SimplifyCFG] Preserve !unpredictable when forming a switch (#221580)
SimplifyCFG turns a chain of equality comparisons into a switch in two
places, performValueComparisonIntoPredecessorFolding() and
simplifyBranchOnICmpChain(), and neither propagated !unpredictable. The
hint was therefore dropped even though it is valid on a switch and the
reverse transform, simplifySwitchOfCmpIntrinsic(), already preserves it.
Propagate the metadata in both. Folding a comparison into a predecessor
merges two decisions into a single switch, so the result is only marked
unpredictable when both of the folded comparisons were. That also makes
chains longer than two blocks work: the fold runs once per predecessor
and reads the metadata back off the switch it built on the previous
iteration.
simplifyBranchOnICmpChain() also emits a range check instead of a switch
when the case values are contiguous. That branch is an exact replacement
for the original one, so it inherits the metadata unconditionally, and
the flag now survives into the machine IR.
Fixes #42658.

[AMDGPU] Fold redundant inf/nan checks into frexp instructions (#214936)
Fixes #204204
The AMDGPU "v_frexp_exp" and "v_frexp_mant" instructions return 0 for
inf/nan inputs. This patch adds a DAG combine
("performFrexpSelectCombine") to fold redundant inf/nan checks with
frexp results, eliminating unnecessary compare and select instructions..
### Patterns folded:
- `select (fcmp uno x, 0), 0, (frexp_exp x)` → `frexp_exp x`
- `select (fcmp oeq |x|, inf), 0, (frexp_exp x)` → `frexp_exp x`
- `select (fcmp ueq |x|, inf), 0, (frexp_exp x)` → `frexp_exp x`
- `select (fcmp ord x, 0), (frexp_exp x), 0` → `frexp_exp x`
- `select (fcmp one |x|, inf), (frexp_exp x), 0` → `frexp_exp x`
- `select (is_fpclass x, finite), (frexp_exp x), 0` → `frexp_exp x`
- Same patterns with `frexp_mant`
The optimization is disabled on SI (Southern Islands) which has
hasFractBug()..
## Test plan
- [x] Added frexp-inf-nan-combine.ll with comprehensive tests for:
- Targets: GFX9, GFX10, GFX11, GFX950 (optimization applies), SI
(optimization does NOT apply)
- Types: f32, f64, f16
- Patterns: NaN clamp, inf clamp, inf-or-nan clamp, reversed select,
not-inf check
- Negative tests: different inputs, non-zero constants, unrelated
comparisons
All existing frexp-related AMDGPU tests pass..

[RISCV] Fix infinite DAGCombine loop with SETCC and SIGN_EXTEND_INREG (#221593)
We generalized (X & -(1 << C1) & 0xffffffff) == C2 << C1 using `sraiw`.
The combine generates a `SIGN_EXTEND_INREG` when simplifying.
However, when C1 is 0 and the sign bit (bit 31) of X is already known to
be zero, `DAGCombiner` sees that `SIGN_EXTEND_INREG` is semantically
equivalent to `AND X, 0xFFFFFFFF` (zext). Because `DAGCombiner`
considers `AND` to be more canonical than `SIGN_EXTEND_INREG` in this
context, it immediately reverts the node back to `AND`.
This caused an infinite DAGCombine loop. This patch disables the folding
when the C1 is zero. That case is covered by a later combine that already
checks if bit 31 is known to be zero.

[OMPIRBuilder] Restore the debug location after the reduction alloca (#221253)
`createReductions` emits the array of type-erased pointers to the
private reduction values in the alloca block, which means leaving the
current insertion point and coming back. The insertion point is
re-established but the debug location is not. Everything emitted
afterwards like the `__kmpc_reduce` and the matching __kmpc_end_reduce
inherits whatever the terminator happened to carry, which is usually
nothing. This could result in a verifier error if program is linked with
openmp runtime that has debug information.
Fix it by restoring the debug location along with the InsertPoint.

[analyzer] Fix crash destructing element of a sugared array type
ExprEngine::makeElementRegion falls short trying to determine the
element type of an array that involves a type aliasing a static array
type.
This leads to a crash in ExprEngine::ProcessMemberDtor where it assumes
that element type is a CXXRecordDecl, while it is still a type alias to
a static array type.
getBaseElementType is the canonical way to desugar and peel off the
array dimensions.

[CMake] Link only the MLIR dialects ClangIR uses (#221616)
CIR's sources reference Arith, DLTI, Func, LLVM, OpenACC, OpenMP and
Ptr, and cir-opt registers only the CIR dialects plus MemRef and LLVM.
Link those instead, which keeps Linalg, Vector, SPIRV, SparseTensor,
Tosa and GPU out of the clang build graph.
CLANG_ENABLE_CIR=ON adds 2135 build edges to the clang target; this
removes 694 of them.

[CIR] Derive lowering attr names from cppClassName, not the def name (#220891)
CIRLoweringEmitter built its CXX_ABI_ALWAYS_LEGAL_ATTRS entries with
GetOpCppClassName, which splits the TableGen def name at the first
underscore. That works only while every def is named
CIR_<CppClassName>Attr.
When one is not, the emitter writes an `isa<>` for a class that does not
exist, and the failure lands as a compile error in generated code.
Attributes carry the authoritative name in cppClassName, which
GenerateAttrToValueVisitor was already reading. Factor that out as
GetAttrCppClassRef and use it for both attribute paths.
GetOpCppClassName
stays for operations.

[MLIR][Arith] Don't narrow shifts whose amount can exceed the target width (#218495)
A shift by an amount >= the operand bitwidth is poison. Narrowing
changes that bitwidth, so an amount valid at the original width (e.g. 32
for i64) can become poison at the narrowed one (>= 32 for i32),
miscompiling `4 >> 32` from 0 to 4.
Only narrow shifts when the shift amount is provably below the target
width.

This patch fixes the issue by initializing the fields in the test to
true, which maintains the behavior prior to the new fields being added.
Additionally, this patch does a similar drive-by fix to the
SuggestAnnotations field (added in
https://github.com/llvm/llvm-project/pull/205764). Although there has
been no MSan report, that's likely either an MSan false negative or
insufficient test coverage.

[OpenMPOpt] Bound indirect-call specialization instead of paying for all of it (#219323)
`registerAAsForFunction()` seeds `AAIndirectCallInfo` unconditionally,
so device
code pays for specializing every indirect call site. Device code routes
many
calls through function-pointer tables and virtual dispatch, so a call
site can
see every address-taken candidate in the module, and the if-cascade
`AAIndirectCallInfo` builds over them is quadratic.
Skip specialization at a call site with more than three possible
callees,
overridable with `-openmp-opt-max-callees-for-specialization`. The bound
is a
threshold on the call site rather than a limit on how many callees get
specialized: the Attributor asks about each callee with the same total,
so a
site above the threshold keeps its indirect call instead of getting
three direct
ones plus a fallback.
Measured on a generated module with a 256-entry device function-pointer
table,
2048 dispatch functions and 64 target regions, gfx90a,
`opt -disable-verify -passes='openmp-opt,lto<O3>'`, min of 3 runs:
| | cap 3 | no cap |
|-----------------------------------------|-------|--------|
| LTO pipeline | 13.3s | 34.4s |
| final module, IR lines | 340k | 511k |
| cascade equality tests after openmp-opt | 310 | 499 |
The cost is not in `openmp-opt` itself, which is 1.23s either way; it is
in what
the rest of the pipeline does with the cascades. Sites at or below the
threshold
are still specialized, which `indirect_call_specialization_cap.ll`
covers from
both sides.
This PR previously carried two other changes, now split out as #221449
(loop
runtime callbacks) and #221450 (the worker-count gate), per @abidh's
request.
Tested on gfx90a: `llvm/test/Transforms/{OpenMP,Attributor}` 260 passed,
1
unsupported.

[libomp] Set `KMP_USE_YIELD=2` when `OMP_WAIT_POLICY=active` if it's not specified explicitly (#199628)
This patch sets `KMP_USE_YIELD=0` when `OMP_WAIT_POLICY=active` and
`KMP_USE_YIELD` is not explicitly set by the user. This is the same as
the value of `KMP_BLOCKTIME` is set to infinite when `KMP_BLOCKTIME` is
not explicitly set and `OMP_WAIT_POLICY=active`.
### Background
`KMP_USE_YIELD` is an environment variable for libomp to control the
behavior of threads when they are idle. We can specify 0, 1, or 2 as the
value of `KMP_USE_YIELD`. As I read the code, the behavior is as
follows:
- `KMP_USE_YIELD=0`: Threads will NOT yield the CPU when they are idle.
- `KMP_USE_YIELD=1`: Threads will yield the CPU when they are idle.
- `KMP_USE_YIELD=2`: Threads will yield the CPU when they are idle if we
are oversubscribed (i.e., more threads than CPU cores).
The default value of `KMP_USE_YIELD` is 1, which means that threads will
yield the CPU when they are idle.
On the other hand, there is an environment variable `OMP_WAIT_POLICY`
that controls the waiting behavior of threads in OpenMP. The OpenMP 6.0
Specification
(https://www.openmp.org/wp-content/uploads/OpenMP-API-Specification-6-0.pdf)
states as follows:
> The active value specifies that waiting native threads should mostly
be active, consuming processor cycles, while waiting. A compliant
implementation may, for example, make waiting native threads spin.
Therefore, I think it is more consistent to set `KMP_USE_YIELD=2` when
`OMP_WAIT_POLICY=active`.
Note: Using `KMP_USE_YIELD=2` instead of 0 here to avoid hanging when
oversubscribed.
### Performance
To confirm the effect of this patch, I ran SPEC CPU 2017 with several
configurations, including with and without this patch. As a result, I
observed that the performance of some benchmarks improved significantly
with this patch. Also I didn't see any performance degradation. Here are
the details of the performance improvements:
- Machine: Neoverse V2 (Grace, binding 64 threads to 64 cores)
- Configuration: `OMP_WAIT_POLICY=active OMP_NUM_THREADS=64`
| Benchmark | Performance Improvement |
|-|-|
| 621.wrf_s | 2.6x |
| 628.pop2_s | 5.5x |
---
In conclusion, I think it's reasonable to set `KMP_USE_YIELD=0` (or 2)
by default when `OMP_WAIT_POLICY=active` is specified, when the user
likely expects the threads to be active while waiting.
Resolve #181784.

[lld][MachO] Ignore relocated bytes when folding LSDAs (#220155)
AArch64 exception tables reference type info through PC-relative
pointer-to-GOT relocations. The assembler leaves the negated field
offset in each relocated field, which the linker ignores, so identical
tables differ in their raw bytes and are never folded. Treat
__gcc_except_tab like __eh_frame and zero the relocated fields before
ICF hashes and compares it.
Folding these LSDAs exposes a latent issue: the LSDA pointer of a DWARF
FDE is resolved to an InputSection when the FDE is parsed and is never
canonicalized after ICF. A function that is unwound via its FDE and
whose LSDA was folded away therefore gets an __unwind_info LSDA entry
computed from the dead input section. Fixed it in the same commit.
This patch is LLM-driven, but the issue was observed in production and
the test is reduced from the production object.

Log Message:
-----------
[Clang][Modules] Fix ODR handling of types found through using-declarations (#221839)
Fixes #78850.
Clang can diagnose an ODR violation for identical definitions when a
type is
found directly in one module's global module fragment and through a
using-declaration in another. The lookup routes produce different AST
type
wrappers even though they refer to the same declaration.
Normalize `UsingType` to the target declaration's type before hashing
it. Keep
the keyword and qualifier from the use site, rather than from the
using-declaration. This also lets the hash distinguish differently
qualified
uses without canonicalizing away meaningful spelling differences.
The normalization exposes an existing assertion in the enum ODR
diagnostic
path: `AddEnumDecl` hashes canonical underlying integer types, but the
diagnostic emitter compares hashes of their spelled types. Compare the
actual
underlying integer types instead, while retaining the original spelling
in the
diagnostic. The extended `pr76638.cppm` regression also reproduces the
assertion
without the normalization change, when both underlying types are found
through
same-named using-declarations.
Use `EnumDecl::getIntegerType()` for this comparison so ignored cv
qualifiers
in the enum-base do not incorrectly take precedence over an actual
difference
in enumerator initializers. A regression checks that diagnostic as well.
Regression coverage includes both lookup directions, typedefs and
aliases,
record and enum types, chained using-declarations, templates, and
negative
tests for qualification, elaborated keywords, and cv qualification.
Remove the
now-fixed #78850 example from the modules documentation.
## Validation
Built from main at `44a4dbf32a6b54de32e4d064756d7a6ba5b9e808` plus this
patch,
in Release mode with assertions enabled on Windows x86-64 (X86 backend,
Clang 23.1.0 bootstrap, VS 2022 SDK).
| Suite | Passed | Unsupported | Expected Failures |
| :------------ | -----: | ----------: | ----------------: |
| Clang Modules | 914 | 34 | 0 |
| Clang PCH | 289 | 6 | 2 |
| **Total** | 1,203 | 40 | 2 |
Unexpected failures: **0**.
- Removing both implementation changes and rebuilding on the same main
base
makes both affected regression tests fail: the new lookup test reports
false ODR errors, and the extended enum test asserts while diagnosing an
ODR
violation. Restoring the changes and rebuilding passes both complete
suites.
- The cv-qualifier regression also fails with the earlier comparison of
spelled underlying types, then passes with `getIntegerType()`.
- Changed implementation lines pass clang-format checks; `git diff
--check`
passes.
The original release/23.x patch was also tested: 1,180 passed, 39
unsupported,
2 expected failures, and no unexpected failures across Modules and PCH.
Its
unmodified implementation reproduced the false-positive diagnostics,
missed
qualification diagnostic, and enum assertion.
Other platforms and configurations have not been tested locally.
This is a targeted ODR fix, not a general resolution of Clang's
remaining C++
module limitations.
The fix is also relevant to release/23.x; a backport can follow upstream
review
and merge.

Eight of the ASTContext type pools key on a QualType, or on a QualType

serialization overhead before probing the hash table.
Switch to UniquingSet. Define `QualTypeBoolInfo` for three pools that
key on a QualType and a bool, because DenseMapInfo has no bool
specialization.
After the canonical type is built, these getters re-probe to refresh the
insert token. A token is now a hash (#218190), not a bucket, so nothing
invalidates it; fold the re-probe into the assertion it feeds.

[MLIR] AllocaOp canonicalization for array allocation in LLVM dialect (#221508)
Add the following canonicalization pattern to AllocaOp in MLIR's LLVM
dialect:
```
%n = constant(N)
%alloca = llvm.alloca %n x Ty
```
->
```
%one = constant(1)
%alloca = llvm.alloca %one x !llvm.array<N x Ty>
```
Here N is a constant representable with 64-bits. With this
canonicalization, the AllocaOp will be translated to `alloca [N x Ty]`
in LLVM IR. Without this canonicalization, the AllocaOp was translated
to `alloca Ty, N`. We prefer `alloca [N x Ty]` over `alloca Ty, N` for
fixed-size array allocation.
See [this
RFC](https://discourse.llvm.org/t/rfc-allocaop-canonicalization-in-mlirs-llvm-dialect/91734)
for more detailed problem motivation and description.

[libc++][test] Test SFINAE for `optional`'s operators in C++17 (#221643)
We have been intentionally constraining `optional`'s comparison
operators since C++17, so it is probably better to test the constraints
in C++17 mode. Given the constraints are standardized only since C++26
(via P2944R3), `LIBCPP_STATIC_ASSERT` is used in old modes.
In order to do this, `test_comparisons.h` is reworked to expose
`NonComparable` and `EqualityComparable` in pre-C++20 modes, and a new
type `TotallyOrdered` is invented as a replacement of
`ThreeWayComparable` in old modes.
As drive-by, also switches to use `// REQUIRES: std-at-least-c++17` in
touched test files, and adds previously missed includes of
`<type_traits>`.

[LLVM][NVPTX] Add Rubin extensions for G2S Tensor intrinsics (#220029)
This change adds support for the Rubin-extended Global-to-Shared tensor
copy intrinsics for both the Cluster and CTA variants:
1. 32-bit multicast mask support: the G2S Cluster intrinsics are now
overloaded on the multicast mask type (i16/i32); an i32 mask lowers to
`.multicast::cluster::32b`.
2. Data-validity reporting through the mbarrier: all G2S Cluster and CTA
intrinsics, including the property-override forms, take a trailing `i32
%validate_pattern` immediate (range [0, 6)) that selects a
`.mbarrier::report::validity` qualifier. It defaults to 0 (disabled).
3. Override tensor map properties: the G2S Cluster and CTA intrinsics
now support `.override::global_address`, optionally followed by
`.override::global_dim` / `.override::global_dim_stride`, across all
load modes. The dim/stride overrides apply to tile mode only; im2col and
gather4 support the global-address override only.
The new `validate_pattern` argument changes the IR signatures of all G2S
intrinsics; legacy declarations are auto-upgraded with the missing
trailing arguments defaulted to 0, and the multicast mask type selects
the overload. The MLIR NVVM `CpAsyncBulkTensorGlobalToSharedClusterOp`
is updated to build the new signature.

[X86] Fold atomic loads into compares (#221290)
A compare of an atomic load kept the load in a register (mov + cmp/test)
where a compare of a regular load folds the load into the compare's
memory operand. The folded form performs a single full-width load, and
on x86 an ordinary load already provides every ordering up to seq_cst,
so folding is legal for any non-extending atomic load.
Add isel patterns folding an atomic load into CMP (mi/mr/rm forms across
i8/i16/i32/i64). Compare-to-zero already reaches these via EmitTest;
nonzero and register compares are emitted as a flag-only X86ISD::SUB (to
enable CSE with a real subtract) whose load the peephole then folds. The
peephole cannot move an ordered access, so those never folded for atomic
loads. Emit X86ISD::CMP instead when an operand is a foldable atomic
load: it has no non-atomic sibling to CSE with anyway.
x86lint reports 5854 "load foldable into compare" sites in a release
build of Firefox's libxul.so; sampling shows the majority are
atomic-load compares of the kind this folds -- mozilla::Atomic and
std::atomic loads, MOZ_LOG level checks (an Atomic<LogLevel>), and Rust
core::sync::atomic and log-crate level checks.

[CMake] Move -Wno-unused-but-set-parameter from MLIR up to LLVM (#221824)
This warning is known to have false positives with GCC versions before
14.
Since 3aec6a40bb4e49f9ea181ac5c949b6c7c20a5465, this warning appears
when building LLVMSupport as well - thus move the disabling of the
warning up from MLIR to all of LLVM.
In HandleLLVMOptions, the common procedure is to not check for whether
the options are supported or not, but to just hardcode the version
ranges where the options are supported, per compiler.
This option (and -Wunused-but-set-parameter) is available in GCC since
long before our minimum required version.

[ORC] Add SymbolNameSpec, hoist name mangling into Shared.
Introduce two Shared, ExecutionSession-independent pieces:
- SymbolNameSpec (Shared/SymbolNameSpec.h): a StringRef paired with a
SymbolNameKind (Verbatim, Linker, IR, C) describing the naming level
a symbol name is expressed in. A lightweight, dependency-free value
type, so it can describe interface-name constants in Shared headers.
- Mangler (Shared/Mangler.h, Shared/Mangler.cpp): the linker
name-mangling logic factored out of MangleAndInterner. It holds only
a ManglingMode (no ExecutionSession or SymbolStringPool), so names
can be mangled on the executor side as well as the controller
side. It exposes withMangledNameDo (which avoids allocating when
mangling is a no-op) and a mangledCopy convenience, both dispatching
on the spec's SymbolNameKind.
MangleAndInterner becomes a thin wrapper: it derives a ManglingMode
(from an ABIName / ManglingMode / DataLayout), holds a Mangler, and
interns whatever the Mangler produces. Behavior is unchanged.
This lets lookup utilities eventually accept C / IR source names and
mangle them to linker level on the caller's behalf, rather than
requiring pre-mangled names. The MangleAndInternerTest unit tests are
renamed to ManglerTest and now exercise Mangler directly;
MangleAndInterner is left untested since it is slated for removal.

[X86] X86CompressEVEX - Fold AVX-512 sign-mask compares to MOVMSK (#216884)
## Summary
Fold AVX-512 complementary signed sign-test masks to the corresponding
MOVMSK instructions in `X86CompressEVEX`.
AVX-512 lowers comparisons such as:
- `X >= 0`
- `X > -1`
to `VPCMP*` producing a k-mask followed by `KMOV`.
For 128-bit and 256-bit B/D/Q forms, these masks can instead be obtained
from the source sign bits using:
- `VPCMPB` -> `VPMOVMSKB`
- `VPCMPD` -> `VMOVMSKPS`
- `VPCMPQ` -> `VMOVMSKPD`
followed by the appropriate complement.
## Details
The complement is restricted to the meaningful lane-mask bits so that
unused upper bits retain the zero-extension semantics of `KMOV`.
For the 32-lane byte case, all 32 bits are meaningful, so `NOT32r` can
be used directly without clobbering EFLAGS.
The transformation is limited to 128-bit and 256-bit B/D/Q forms with a
single non-narrowing `KMOV` consumer.
The matcher also verifies the expected zero/all-ones producer for the
comparison constant and avoids the fold when required register or
EFLAGS liveness constraints are not satisfied.
## Tests
Added:
- end-to-end CodeGen coverage for the affected sign-mask cases;
- dedicated MIR coverage for `X86CompressEVEX`;
- negative MIR cases covering:
- multiple mask uses;
- source clobbers;
- unsupported predicates/constants;
- narrowing `KMOV`;
- 512-bit vectors;
- extended registers;
- live EFLAGS;
- masked-move consumers with incompatible mask polarity;
- incorrect all-ones producer width;
- dead `KMOV` destinations.
Existing `VPMOV*2M + KMOV -> MOVMSK` coverage is preserved.

Log Message:
-----------
[CoroSplit] Don't go sub-word for suspend index (#221374)
Currently, `CoroFrame` selects the coroutine suspend index type
(`SwitchIndexType`) using `Type::getIntNTy(Context, IndexBits)`. For
coroutines with fewer than 256 suspend points, this produces
sub-byte/sub-word integer types (such as `i1`, `i2`, or `i8`) in the
coroutine frame struct.
On targets whose `DataLayout` specifies `-n32` (no legal sub-32-bit
integer types), storing and loading sub-word integer fields in memory
forces the backend to emit read-modify-write sequences on every
coroutine suspend and zero-extension masks on every resume.
Use `DataLayout::getSmallestLegalIntType(Context, IndexBits)` when
selecting `SwitchIndexType` so that targets respect their legal native
integer width.

[clang] Unique more ASTContext type pools in a UniquingSet. NFC (#221898)
Similar to #221850.
Eight pools key on a small tuple of types, integers and pointers, yet
each get*Type() serializes that into a FoldingSetNodeID and hashes it
out of line before probing. Switch to UniquingSet.
These getters re-probe after building the canonical type. A token is a
hash (#218190), not a bucket, so nothing invalidates it. Drop unneeded
assertions.

[SelectionDAG] Widen vector math libcalls when no routine is available (#218948)
`tryExpandVecMathCall` currently only checks for a vector math routine
matching the node's exact vector type, unrolling when none is found.
This is suboptimal, and can lead to crashes for scalable types (which
cannot be unrolled).
This PR implements widening to first check if a routine with a wider vec
type exists before falling back to unrolling.
Example:
```
; llc -mtriple=aarch64 -mattr=+sve -vector-library=sleefgnuabi crash.ll
define <vscale x 2 x float> @frem_nxv2f32(<vscale x 2 x float> %a, <vscale x 2 x float> %b) {
%res = frem <vscale x 2 x float> %a, %b
ret <vscale x 2 x float> %res
}
```
NOTE: When the routines take a mask (e.g. if they're scalable variants),
only relevant lanes are activated. Vectors are padded with copies of the
operand to avoid running on poison.

G_ADDRSPACE_CAST, and preserve it through SelectionDAG vector
scalarization and splitting.

[CodeGen] Correctly classify/mark dead defs when adjusting lane liveness (#215595)
Despite what the documentation of `adjustLaneLiveness` states, the
method never sets dead flags on dead def operands, even when missing
dead flags can later lead to machine verifier errors.
This makes the method identify dead definitions from definitions that
are initially thought to be alive, and makes it add a dead flag on the
last definition of a virtual register, matching the behavior expected by
the machine verifier (ref. "Instruction ending live segment on dead slot
has no dead flag").
`adjustLaneLiveness` and `detectDeadDefs` now also use the same
mechanism to identify dead definitions. It relies on comparing the
defined lanes of a definition with those that stay alive after it.

[CIR] Drop the redundant suffix from the inline kind mnemonic (#220892)
inline_kind was the one CIR enum attribute mnemonic still repeating what
its
C++ enum class name says. The attribute now spells
`#cir.inline<always_inline>`. The operation argument keeps the name
inline_kind, since that is the accessor name, so the printed form reads
`inline_kind = #cir.inline<always_inline>`.
The enum's summary also becomes "inline kind" rather than the camelCase
"inlineKind", which is what generated docs show now that
CIR_InlineKindAttr
no longer overrides it.
25 CHECK lines change across four test files. Nine are in an
aarch64-registered-target test, unsupported in an X86-only build, but
the
substitution matches the two CIR tests that do run.

[CIR] Cast alloca for function parameter to the right address space (#220836)
Function parameters are stored into temporary allocas and for
address-space aware targets allocas may yield pointers to address spaces
that are different from default address space or the address space of
the parameter type. Do a cast to avoid mismatch. The address space
mismatch was reproduced using cir.ternary op returning a function
parameter and a local variable. For local variables and return
temporaries we already cast alloca address space to temporary address
space but not for function parameter allocas.

[lldb] Fix flaky TestConcurrentTwoWatchpointsOneSignal (#221697)
`g_watchme` was declared right next to `g_sigusr1_count`. Hardware
watchpoints round the watched address/size to an alignment boundary, so
a watchpoint on `g_watchme` could also end up covering
`g_sigusr1_count`. When the signal thread's handler touches
`g_sigusr1_count` while the watchpoint threads write `g_watchme`, that
overlap causes a spurious hit and lldb can attribute the stop to the
wrong thread.
See llvm.org/PR35228.
Fix: group the watched field and its padding into a single aligned
struct (`WatchMePadding`), so the compiler is guaranteed to lay out the
data and padding together.
Assisted by Claude.

[ORC] Move Mangler implementation from OrcShared to OrcJIT (#221942)
Many OrcJIT clients don't directly depend on OrcSupport, and so broke
when e91092685eab moved mangling from OrcJIT to OrcSupport.
We want to reorganize these libraries in the not too distant future.
Rather than forcing clients to update dependencies that may change again
soon, move the code (but not the header) back into the OrcJIT library.
We can address the mismatch between the header's and implementation's
home during the library reorganization.

Python will fail to initialize if `%SystemRoot%` is not defined which

fails and returns early. lldb still crashes but gives a clue as to why
that's the case.

[libc] Simplify RPC lock handling to be scalar on the GPU (#221805)
Summary:
This interface was originally written in a complicated way as a
pessimistic bet against NVIDIA's independent thread scheduling. The idea
was that it would work regardless of which set actually executed the
function. The problem is that this forces the operation to be an
expensive vector operation.
This should be safe, we already have other safeguards against ITS in the
main loop. When this function is called, we know that the index and lane
mask are convergent in the set. ITS says the true threads executing this
could be greater than returned. But in this case the 'locked' value
would not be shuffled in, it would not see that it got the lock, and
loop again in a different mask set.
The complicated thing about ITS is mostly that any lanes that share a PC
will report convergent, but that should not bite us here as we already
guard against that before calling this.

The `I32EnumAttrCase` family carries an `Attr` half, and an

derive
from `EnumInfo`. Upstream says of those forms that they "are not needed

using the newer `EnumCase` form".
Rename all of them to `I32EnumCase`, `I32BitEnumCaseNone`,
`I32BitEnumCaseBit` and `BitEnumCaseGroup`. The group class drops its
width
prefix because the modern spelling takes the width from its cases.

[GlobalISel] Migrate various generic wip_match_opcode combines to MIR-pattern. (#220213)
This patch converts a batch of GlobalISel combine rules from
hand-written C++ matchers to declarative MIR patterns preserving the
behavior. It also along with adds two functional changes (a
rule-ordering fix and an out-of-bounds bug fix) are described below.
- `select_same_val` → `select_same_val_trivial` +
`select_same_val_equiv` group
- `select_constant_cmp` → `_false` / `_true` / `_general` group
- `simplify_add_to_sub`, `add_p2i_to_ptradd` → `GICombinePatFrag`s
- `commute_shift` → `commute_shift_frags` (C++ residue reduced to
`isDesirableToCommuteWithShift`)
- `combine_i2p_to_p2i`, `ptr_add_zero`, `sext_trunc_sext_load` →
patterns.
- funnel-shift / rotate / `ashr_lshr` / `constant_fold_fma` /
`constant_fold_cast_op` / `combine_minmax_nan` → pattern fragments
- **`select_zero_true` / `select_zero_false`:** skip a constant
condition as they fold it to an arm instead strictly better and avoids a
`G_FREEZE` that post-legalization can't clean up.
- **`match_bitfield_extract_from_and`:** mask the AND immediate to the
operand width and reject fields where `lsb + width > size`, preventing
an out-of-bounds `G_UBFX` (fixes an AMDGPU `knownBitsForSBFE` crash).
28 CodeGen tests updated. All diffs are semantically equivalent.

[MemDep] Remove cached non-local defs referencing deleted instructions (#219929)
MemoryDependenceResults::removeInstruction() removed entries from
NonLocalDefsCache when the removed non-pointer instruction was itself a
cache key, but did not remove entries where that instruction was the cached
dependency result.
This could leave a stale instruction reachable through NonLocalDefsCache
after GVN erased it. A later non-local load query could then consume the
dangling dependency and crash in GVN::analyzeLoadAvailability().
Use ReverseNonLocalDefsCache to remove forward cache entries whose
dependency result references the removed instruction, keeping both maps
consistent.
Related removal paths now use the existing reverse-map helper, with
consistency assertions to catch future map divergence.
Fixes #219885.
A downstream Mono integration has also hit #219885 in practice when

[clang][AST] Fix infinite recursion when printing fully qualified template parameters (#219044)
This fixes an infinite recursion crash that was introduced in #206041.
When printing a `DeclRefExpr` using
`PrintingPolicy::FullyQualifiedName`, we were previously trying to print
the fully qualified name of all decls. However, when the decl is a
template parameter, its `DeclContext` is the template specialization
itself. If a template specialization's arguments depend on that same
template parameter (e.g., `template<int Count> struct
View<int[Count]>`), attempting to print the qualified name forces Clang
to recursively evaluate the enclosing context. This led to unbounded
recursion (`View<int[Count]>::Count` ->
`View<int[View<int[Count]>::Count]>::Count` and so on). Since template
parameters are inherently scoped to their template declarations and do
not require a fully qualified name, this patch resolves the issue by
skipping `printQualifiedName` if the decl is a template parameter
(`!VD->isTemplateParameter()`).
Fixes #218076.

This change was originally implemented by @krzysz00 in #196206, but was

subset of #196206, making it easier to identify and triage any potential

[AMDGPU] Prefer packed minimum/maximum ops for two-input ops (#215449)
A two-input f16 fminimum or fmaximum operation should translate to a
packed two-input minimum/maximum instruction when the target supports
one.
It currently can be selected through the minimum3/maximum3 fallback
pattern instead. That emits a three-input instruction with one input
operand duplicated.
Keep the fallback for nested min/max expressions that can use the real
three-input instruction. Add a higher-priority direct pattern for
non-nested two-input operations on targets with packed IEEE
minimum/maximum opcodes.

[SPIRV] Add matrix type legalization for many float global opcodes (#220782)
fixes #220723
The issue in #220723 is that the global opcodes can not deduce the
element type when the input is a shuffle vector. This is the same issue
as #213783. All we have to do to fix this is to have deduceTypeFromUses
in the SPIRVPostLegalizer know that we need to look up the type from the
results register for these opcodes.
The secondary issue is that there were no matrix tests for any of these
global opcodes so I added them. I did not follow the template started by
the atan2 tests because those are overkill and testing way to much stuff
not related to opcode legalization.

[libc] Update printf_core::Writer to template on character type. (#220669)
This is motivated by working toward `swprintf`.
The primary goal is to enable a `CharT` template type parameter on
`printf_core::Writer`. This requires refactoring how the "overflow
write" logic is set up to get around the limitation on function template
partial specialization.
Key changes to `printf_core::Writer` and friends:
* Separate the overflow write logic from `WriteBuffer` into an
`OverflowWriter` template where specializations handle dispatch, and
remove the `WriteBuffer` subclasses.
* Rename from `WriteMode` to `OverflowMode` to try and shorten the
enumerators with minimal loss to clarity, and reduce the number of modes
to only two: `DROP_OVERFLOW` and `CALLBACK`.
* The number of dynamic function calls for flushing and resizing use
cases stays the same by templating the callback on a `WriteSink`.
At this stage the extra `CharT` template type parameter is added in this
PR mainly to ensure the setup works without running into function
template partial specializations. Fully expanding `Writer` with
`wchar_t` will be done in follow-up PRs.

[cmake] FindLibXml2: keep user-provided LIBXML2_DEFINITIONS (#221294)
LLVM's `FindLibXml2.cmake` (added in #166867) unconditionally does
`set(LIBXML2_DEFINITIONS ${PC_LIBXML_CFLAGS_OTHER})` and puts
`PC_LIBXML_CFLAGS_OTHER` on the imported targets. CMake's own
`FindLibXml2` module only takes pkg-config's flags when the library it
found is the one pkg-config describes; otherwise it keeps whatever
`LIBXML2_DEFINITIONS` the user passed and exposes it through
`INTERFACE_COMPILE_OPTIONS`.
This matters when cross-compiling against a static libxml2 on Windows.
Passing `-DLIBXML2_DEFINITIONS=-DLIBXML_STATIC
-DLIBXML2_LIBRARIES=.../libxml2s.lib` worked with LLVM 22 (CMake's
module): the define reached both the `xmlReadMemory` configure check and
the consumers of `LibXml2::LibXml2`. With LLVM 23 it is silently
dropped, `xmlexports.h` declares the API `__declspec(dllimport)`, the
check fails to link against the static library and
`LLVM_ENABLE_LIBXML2=FORCE_ON` aborts with `Failed to configure
libxml2`. (pkg-config on the Linux host finds the host's libxml2, so
`PC_LIBXML_CFLAGS_OTHER` is empty and unrelated to the library actually
being used.)
Mirror CMake's behaviour: keep the user's definitions unless pkg-config
found the same library, and attach them to both `LibXml2::LibXml2` and
`LibXml2::LibXml2Static`.
Seen while building the Firefox clang 23 toolchains (x86_64 and aarch64
`-pc-windows-msvc`, cross-compiled from Linux with
`LLVM_EXPORT_SYMBOLS_FOR_PLUGINS=ON`).

**AI tool use disclosure** (per the [LLVM AI Tool Use
Policy](https://llvm.org/docs/AIToolPolicy.html)): this change was
developed with Claude Code assisting in the analysis and drafting. The
root cause was established against real 23.1.0 binaries; this cmake
change itself has so far only been verified to apply to 23.1.0 and main
and by code reading, while Firefox's CI validated the equivalent
workaround of passing -DLIBXML_STATIC via the compiler flags. The author
reviewed the change and is accountable for and able to answer questions
about it. Commits carry an `Assisted-by:` trailer.

[mlir][LLVM] Use element allocation sizes when computing struct size (#221742)
`LLVMStructType::getTypeSizeInBits` currently advances by each element's
store size. With the data layout from #221665, this reports 11 bytes for
`!llvm.struct<packed (f80, i8)>`, while LLVM uses the 16-byte allocation
size of `f80` and reports a 17-byte struct.
Round each element's size up to its ABI alignment before adding it to
the
struct size, matching LLVM's `getTypeAllocSize` behavior. Packed structs
continue to suppress alignment gaps before elements, while each element
still consumes its allocation size.
Add regression coverage for packed, unpacked, nested, and array layouts.
Fixes #221665.
Testing: 99 relevant MLIR tests passed; 3 x86-only tests were
unsupported
on the ARM host.

[CIR][NVPTX] Add support for NVVM half type builtins (#221859)
Adds codegen for the following NVVM half type builtins:
- `__nvvm_ex2_approx_{f16,f16x2}`
- `__nvvm_fmin{_ftz,}{_nan,}{_xorsign_abs,}_{f16,f16x2}`
- `__nvvm_fmax{_ftz,}{_nan,}{_xorsign_abs,}_{f16,f16x2}`
- `__nvvm_fma_rn{_ftz,}{_relu,_sat,}_{f16,f16x2}`
- `__nvvm_fma_rn_oob{_relu,}_{f16,bf16,f16x2,bf16x2}`
These are lowered to the corresponding llvm.nvvm.* intrinsics.
This diverges a bit from OG, as no half-type helper is needed here. OG
routes these through `MakeHalfType`, which coerces each argument to the
intrinsic's declared parameter type, appends the intrinsic's defaulted
arguments, and
asserts that no argument is an integer constant expression. None of that
is needed for the builtins in this patch as each already agrees with its
intrinsic on operand and result types, and none has defaulted
parameters. The existing
`emitUnaryNVVMIntrinsic` and `emitBuiltinWithOneOverloadedType<N>`
helpers are therefore sufficient.
More generally, nothing `MakeHalfType` does is half-specific.

[MLIR][NVVM] Add optional llc verification for NVVM dialect tests (#219980)
The motivation is to verify that MLIR NVVM dialect operations lower to
LLVM IR that is accepted by the NVPTX backend. Running llc gives these
tests an extra end-to-end check beyond textual IR matching and helps
catch mismatches between MLIR lowering, NVVM intrinsics, and backend
expectations.
A valid LLVM intrinsic call isn't necessarily selectable for every
combination of its immargs and target features. There is a concrete
NVPTX example in
`llvm/test/CodeGen/NVPTX/tcgen05-mma-collector-b-i8-invalid.ll`. The
intrinsic has a valid signature and individually valid immediate values,
but the combination `kind=i8` and `collector_b=lastuse` is not
supported. LLVM IR verification accepts it, while `llc` rejects it with
Cannot select.
The corresponding MLIR verifier does not duplicate every NVPTX
instruction-selection predicate. It currently checks MLIR-level
properties such as the `disable_output_lane size` and the interaction
between `a_shift` and `collector_a` (the examples are from
`tcgen05.mma`), while the backend owns the complete target-dependent
selection rules. We should improve the MLIR verifier whenever an invalid
MLIR operation can be rejected early, but a targeted integration check
also detects disagreement or drift between those two independently
maintained layers.
Another case is target-version drift. A translation test can be extended
with a new intrinsic variant requiring a newer SM or PTX ISA while
continuing to pass its textual `FileCheck`. Since the existing command
has no target contract, the test does not tell us whether all the
generated intrinsics are lowerable for one coherent target. An `llc`
invocation with explicit `-mcpu` and `-mattr` makes that contract
visible. If a test intended for sm_100a/PTX 8.6 starts using
functionality available only for sm_107f/PTX 9.4, the integration check
reports it immediately.
```
// RUN: %if has_llc_binary && host-supports-nvptx %{ mlir-translate --mlir-to-llvmir %s | %llc-verify -march=nvptx64 -mcpu=sm_<version> -mattr=+ptx<version> %}
```
`%llc-verify` finds `llc` as `lit.util.which("llc",
config.llvm_tools_dir)`.

[acc] Pre-cg pass for handling flang data mapping to offload runtime (#221282)
Introduce acc.map_info as the acc dialect operation that captures a
single mapped object's offload facts (attach point, descriptor kind,
bounds, map flags, and size) so later codegen can lower data clauses to
the offload runtime from one representation.
Add a Flang pre-codegen pass, ACCMapInfoPrep, that materializes
acc.map_info for FIR-typed operands: it infers Fortran descriptor attach
and CFI facts, sizes mapped and privatized storage, and folds paired
enter/exit clause effects into map flags. This keeps FIR-specific
mapping logic out of ACCToLLVM and leaves that conversion to consume
map_info verbatim.

[libc] Implement pthread_getattr_np (#221231)
Implement the GNU extension pthread_getattr_np.
For the stack address and size, the function returns the same value as
pthread_getstack_np. Specifically, this means returning
PTHREAD_STACK_DYNAMIC_NP for the main thread. Since we're not promising
async-signal-safety of this function, we could parse /proc/self/maps
(like glibc does), to get the actual stack VMA, but:
- that's a lot of code
- I'm not particularly fond of relying on /proc for libc features
- the consistency with pthread_getattr_np is nice
For these reasons, I'm not implementing this (or other alternatives like
RLIMIT_STACK) right now. This incidentally means that the current
implementation of this function is async-signal-safe, but that is likely
to change once we add support for additional attributes.
For consistency with glibc, I report the guard size of newly created
threads as zero, regardless of what was present in the thread creation
attributes. I zero the attribute directly during thread creation as it
is not used for managed stacks.

[AggressiveInstCombine] Add shufflevector support to TruncInstCombine (#220218)
Previously, expression graphs containing shufflevector could not be

allowing truncation to propagate through shuffle operations.
The shuffle mask and vector shape are preserved while the operands are
rebuilt with the reduced element type.
This removes the corresponding TODO in TruncInstCombine.cpp.

AddDebugInfo converted the result and argument types of every function

-gline-directives-only ended up with the full type graph of each
signature: derived types, array types, string types and the basic types
they are built from.
Leave the type list empty at those levels which is also what clang emits
for -gline-tables-only or -gline-directives-only. The subprogram of an
omp.target region gets the same treatment.
A single variable is now used to decide this so parameter for the
`addTargetOpDISP` lambda was removed.

[Clang] Fix assertion when a Unicode character is splatted to a vector of its own type (#219987)
Fixes #202317
Comparing an `ext_vector_type` of `char32_t` against one of its own
elements (`V.xyzw < V.x`) splats the scalar to the vector type, and
`-Wconversion` checking then trips `Source != Target` in
`DiagnoseMixedUnicodeImplicitConversion`. `CheckImplicitConversion` does
reject `Source == Target` at the top, but only on the outer types; when
it later strips the vector wrapper off the target it ends up with
`char32_t` on both sides and nothing re-checks that. Every other element
check just happened to tolerate identical types silently, the Unicode
one is the first to assert, which is why this only showed up as a Clang
21 regression.
The fix is at the call site rather than in the diagnostic: once the
vector, matrix and SVE wrappers have been stripped, return early if the
element types are the same. That covers matrix splats and HLSL
truncation to the same element type too, not just this one warning, and
leaves the assertion and the warning's behaviour alone. A genuine
mismatch such as `V.xyzw < u8` still warns as before. Added a test with
the reproducer.
LLM tools were used for this contribution. I've reviewed, built, and
tested the change myself before pushing to GitHub.

[flang][cuda] Inline scalar-to-array assignments in CUDA Fortran device code at -O0 (#221333)
At -O0, `arr = 11` lowers to a `_FortranAAssign` call. In device code
the runtime function's callees join the kernel's call graph, so the
device linker reserves a worst-case stack frame for every kernel
reaching it: `65,720` bytes per thread for a kernel with one such
assignment, versus `0` at -O1.
`InlineHLFIRAssign` already runs at -O0 with `onlyScalarRHS` for OpenMP
target device compilations. This extends that carve-out to CUDA Fortran.
Since a CUDA Fortran module holds both host and device code, the
decision is per-operation via `cuf::isCUDADeviceContext`, and host code
keeps the runtime call.
Only scalar-to-array broadcast is covered.

[Driver][Clang] Add -nodefaultrtlibs (#219496)
On z/OS testing compiler-rt does not work with the -nodefaultlibs since
that option remove both the standard libraries like libc and the
compiler-rt library. On other platforms adding an argument like `-lc`
back to the command line in the test scripts works because the path for
libc (eg. `-L<path>`) hadn't been removed. On z/OS, the standard
libraries are located in data sets and you need to specify them by
complete name (eg. `<HLQ>.SCEELIB(CELQS003)`).
This is adding the option `-nodefaultrtlibs` so the compiler-rt tests
can remove just the compiler-rt libs from the link step.

[AMDGPU] Avoid dangling SSAUpdater reference in PromoteAlloca full-vector store (#215686)
promoteAllocaToVector walks alloca users in use-list order across
blocks. A full-vector store forwards its value operand to the
SSAUpdater, and that operand can be a load from the same alloca in a
dominating block. If the store is visited first, the SSAUpdater holds a
raw pointer to the load; the load is later RAUW'd and deleted, leaving a
dangling reference that causes a crash.
Fix by sorting blocks in reverse post-order before visiting them, so a
forwarded load is always replaced before any store hands it to the
SSAUpdater.

[GlobalISel] Drop redundant scalable-dest check in G_EXTRACT_SUBVECTOR lowering (NFC) (#221934)
The scalarizing lowering of G_EXTRACT_SUBVECTOR bails out for both a
scalable source and a scalable destination.
According to llvm/docs/GlobalISel/GenericOpcode.md, G_EXTRACT_SUBVECTOR
only supports extracting a fixed vector from a scalable vector, never a
scalable vector from a fixed one.
This means that a fixed source implies a fixed destination, making the
DstTy.isScalable() check redundant.
Remove it. NFC.

-----------
[Clang][OpenMP] Don't mark outlined parallel region functions norecurse (#218862)
Clang marks every outlined OpenMP region function `norecurse`, in both
`emitOutlinedFunctionPrologue` and
`emitOutlinedFunctionPrologueAggregate`, and
does the same for the GPU parallel wrapper. For a `parallel` region that
is not
true: the body is reached through the function pointer the runtime is
handed, and
if the body opens another parallel region the runtime's parallel entry
is
re-entered while the first call is still live, so the entry and the body
sit in a
call graph cycle. `rpo-function-attrs` propagates the annotation off the
body and
onto the device runtime's parallel entry once internalization makes it
internal,
and a nested parallel region can then be folded away.
This drops the annotation where the runtime can re-enter the function —
the
parallel bodies and the GPU data sharing wrapper — and keeps it where it
holds by
setting it on the teams and target bodies, which are entered once and
never
handed back to the runtime as a callback. Task bodies never carried it,
as they
are emitted through `GenerateCapturedStmtFunction`.
Where the attribute is true `function-attrs` still infers it, so a
program whose
parallel regions do not nest loses nothing. Splitting one attribute
group into
two renumbers the groups in the combined-construct codegen tests, and
that
accounts for all of the test churn.
The new offload test covers the nested case that motivated this.

[mlir][vector] Extend `ShapeCastCreateMaskFolderTrailingOneDim` (#219494)
Extends `ShapeCastCreateMaskFolderTrailingOneDim` so that it also works
for leading unit dims. For example,
```mlir
%1 = vector.create_mask %c1, %c1, %dim, %c1 : vector<1x1x[4]x1xi1>
%2 = vector.shape_cast %1 : vector<1x1x[4]x1xi1> to vector<[4]x1xi1>
```
is folded as:
```mlir
%0 = vector.create_mask %c1, %dim : vector<[4]xi1>
```
To better reflect the extended functionality, the updated pattern is
renamed as:
* `ShapeCastCreateMaskFolderBoundaryUnitDim`.
It takes a template parameter to specify whether to consider
the leading or the trailing unit dims.

[OpenMP][OMPD] Add symbol lookup helper for GDB plugin (#221956)
On LLVM today, `libompd.so` exists with `dlopen`, finds each API with
`dlsym` and checks error with `dlerror`.
**Missing piece**: There is no single place that:
load this library
look up this name
give me a real error string
**Issues**:
A later change would have to edit 30+ calls sites,
`dlerror()` is easy to misuse,
failures often drop the OS error string.
**Fix**: Add these helpers:
`ompd_load_library(path)` – load `libompd.so`
`ompd_get_symbol(name)` – look up one function
`ompd_get_dl_error()` – last error text or NULL
The plugin still uses `dlopen/dlsym` inside that helper. No LLVM
Support. No `setup.py`.

This option was only settable through the hidden -enable-sign-dependent-

documentation describes honoring a dynamically-changeable rounding mode,
which is what strictfp is for; this relic predates any design for FP
mode controls.
Replace the one ARM consumer with strictfp checks, and remove the
predicate from the patterns which checked it. There were also no tests
for the pattern, so add those.

[lldb][Windows] Translate file descriptors between CRT instances (#217126)
The official LLVM and lldb builds use `LLVM_ENABLE_RPMALLOC`. This
changes the default CRT allocator to rpmalloc for performance reasons.
In doing so, it also changes the CRT linkage from dynamic (`/MD`) to
static (`/MT`).
Since the CRT is the one managing file descriptors on Windows, its
universe is now scoped to a module. For lldb, this means we have three
fd-spaces: the driver (lldb/lldb-dap), liblldb, and Python.
We usually pass files around as file descriptors. This breaks when we do
it between modules.
Fortunately, the C runtime provides us with helpers to translate between
the process scoped HANDLEs and file descriptors. This way, we can
allocate an fd for a handle passed across modules. For Python, there's
the [`msvcrt`](https://docs.python.org/3/library/msvcrt.html) library we
can use to translate.
Fixes #216679.

Add Instruction::user_iterator. (#220391)
Users of an Instruction have a special property: they're guaranteed to
be Instructions themselves. Add a specialized iterator to take advantage
of this property.
See the change to IVDescriptors.cpp for an example of how this
simplifies code.

Log Message:
-----------
[OpenMPOpt] Look inside the callbacks the loop runtime functions are handed (#221449)
The `__kmpc_{distribute_,for_,distribute_for_}static_loop_*` functions
take the
loop body as a callback, so a parallel region written inside that body
is
reachable from the kernel only through the runtime call. `AAKernelInfo`
could not
see it: it recorded an unknown reaching region, and every kernel using
those
functions got a worker state machine whose only option was an indirect
call to
whatever it was handed.
Describe each function's callback argument in `OMPKinds.def`, attach
`!callback`
metadata, and fold the callback's `AAKernelInfo` state into the
caller's, so the
state machine can dispatch directly to the regions the body reaches. The
two
"more than one callee means give up" checks are relaxed for functions
carrying
`!callback`, since that edge is analyzable by construction; the
conservative
unknown-region record is kept for the case that motivated it, a callback
we only
see a declaration of.
These calls still block SPMD-ization, and the `TODO` saying they need
not is
replaced with the obstacles that actually remain. A plain `distribute`
spreads
iterations over teams, so the runtime runs it with TId 0 and a team size
of one;
SPMD-izing has every thread run its block's whole share. The
thread-indexed
families are stopped by the transform rather than the analysis: guarding
puts
single-threaded code behind a block-wide barrier, and a barrier inside a
body
only some threads run is divergent.
Ported from AMD's ROCm fork, `8176194f36b9`, which also used the
analysis to
SPMD-ize these kernels; that part is left out because it is disabled by
default
downstream after regressing applications.
Tested on gfx90a: `llvm/test/Transforms/{OpenMP,Attributor}` 260 passed,
1
unsupported. `offload/test/amdgpu-amd-amdhsa` 516 passed, including the
new
Fortran reproducer. No kernel in the AOMP smoke and smoke-fort suites
changes
execution mode.

workflows/release-binaries: Fix zstd compression (#219587)
23.1.0 was the first e2e release with zstd archives. I noticed that once
it shipped they didn't have a meaningful size improvement over the
pre-existing archives. Turns out this is because by default zstd
compresses over a 128MB window which wasn't large enough to get
meaningful savings. We now use 1GB for this which uses more memory but
should take the archive from the 1.8GB that the xz release is, to ~1gb.
I played around with a few options and this was the best time vs
compress vs memory usage ratio.

[Attributor] Compare an indirect call's callee in the program address space (#222097)
Specializing an indirect call emits, for each candidate callee, an
`icmp` between
the call's callee operand and the candidate. The operand was first
normalized to
address space 0, but the candidates are functions, and functions live in
the
target's program address space. Where that is not 0 the two sides of the
comparison had different types and the `icmp` asserted:
```
Instructions.h:1266: void llvm::ICmpInst::AssertOK(): Assertion
`getOperand(0)->getType() == getOperand(1)->getType() &&
"Both operands to ICmp instruction are not of the same type!"' failed.
```
Normalize to the program address space instead. It is 0 unless a target
says
otherwise, so nothing changes for those; for `spirv64`, whose data
layout sets
`P9`, it is the difference between comparing a `ptr` with a `ptr
addrspace(9)`
and comparing two `ptr addrspace(9)`.
This was found on the `intel-sycl-gpu` builder, which crashed compiling
`offload/test/offloading/nested_parallel_reduction.c` for
`spirv64-intel` once
841d4ad6b315 let that call site reach the specialization path: before,
it took
the single-callee promotion path, which emits no comparison. The bug it
reached
is older than that commit and is not specific to OpenMP, so the test
added here
is a plain Attributor one that needs only a data layout with a non-zero
program
address space.

[lldb] Fix infinite recursion in ArchSpec's core matching (#221899)
`target create` never returns for a little-endian 32-bit MIPS ELF file,
on any host whose platform advertises `armv7m`/`armv7em` compatibility.
On Darwin that is every platform, since
`PlatformDarwin::GetCompatibleArchs()`
lists both for every arm64/arm64e host and falls through to that same
list
for any other host core. It is found by `lldb-target-fuzzer`.
Reproduce with a 52-byte ELF32 header (`ELFCLASS32`, `ELFDATA2LSB`,
`e_machine = EM_MIPS`, `e_flags = EF_MIPS_ARCH_32`, everything else
zero),
saved as `mips32el.elf`:
```
(lldb) target create mips32el.elf
```
This never returns. Attaching a debugger to the hung process shows the
same three frames looping forever, with the call stack never growing:
```
frame #1: cores_match(core1=eCore_arm_armv7m, core2=eCore_mips32el, try_inverse=false, ...) at ArchSpec.cpp:1575 [inlined]
frame #2: ArchSpec::IsMatch(rhs=..., match=CompatibleMatch) at ArchSpec.cpp:1449
frame #3: Platform::IsCompatibleArchitecture(...) at Platform.cpp:1193
```
`cores_match()` checks `core1` against `core2`. When nothing matches and
the caller did not ask for an exact match, it sets `try_inverse` and
retries once with the two cores swapped. It retries because the rule
tables are not symmetric: a core lists only what it accepts, not
everything
that accepts it.
Every case that reaches this fallback must leave `try_inverse` false on
the
way out, so the swap happens at most once. Three cases,
`eCore_arm_armv7em`, `eCore_arm_armv7m`, and `eCore_mips32el`, instead
set
it back to true unconditionally. When both sides of a comparison are one
of these three, the swapped call re-arms `try_inverse`, and the tail
call
back into `cores_match()` recurses forever.
This is a tail call, so an optimizing compiler turns the recursion into
a
loop instead of a growing stack. That is why the process spins instead
of
crashing with a stack overflow.
The three cases cannot simply leave `try_inverse` false like their
siblings. `ArchSpec("mipsel").IsCompatibleMatch(ArchSpec("mips64el"))`
is
true today only because of this same swap: `eCore_mips32el`'s own rule
says
nothing about 64-bit MIPS, but `eCore_mips64el`'s rule accepts any
32-bit
MIPS core with the same endianness, and only the inverted comparison
reaches that rule.
Instead, split the switch into a one-directional helper that never
recurses, and try both directions from a plain, non-recursive wrapper:
```
cores_match(A, B) := cores_match_one_direction(A, B) ||
cores_match_one_direction(B, A)
```
This keeps every existing one-directional rule exactly as it was,
including
the mips32el/mips64el rule above, and makes a second retry impossible no
matter what any case does.
Adds two regression tests to ArchSpecTest.cpp. One asserts that the
previously-hanging pairs now return false right away. The other locks in
the two relationships that depend on checking both directions, so a
future
change cannot bring the recursion back by "fixing" the three cases the
naive way.

[lldb] Remove ConstString from CommandObjectType interfaces (#218811)
CommandObjectType was creating ConstStrings type names, function names,
etc. before they needed to be. I'd like to remove ConstString from the
DataFormatter code entirely, so pushing the creation down as far as
possible first is a good first step.
The only remaining use (outside of function arguments) is
ScriptAddOptions. I need to understand it more before I can really
remove it.

[clang][docs] Generate diagnostics reference as Markdown (#221361)
Generate Clang's diagnostics reference from MyST Markdown rather than
reStructuredText. Update diagnostic-group documentation to use native MyST
roles and references, and have the TableGen emitter produce MyST list tables
for diagnostic alternatives.
The new list-table emission code is more verbose, but it is conceptually
simpler, since it's just tracking nested indentation as it emits table cells.
Here's a sample of the table markdown output:
```
* - {warning}`warning:` {diagtext}`They say`
- :::{list-table}
:widths: auto
* - {diagtext}`good`
* - {diagtext}`bad`
:::
-
- :::{list-table}

* - {diagtext}`food`
* - {diagtext}`forests`
:::
- {diagtext}`are`
- :::{list-table}
:widths: auto
* - {diagtext}`good`
* - {diagtext}`bad`
:::
- {diagtext}`according to` {placeholder}`D`
```
See clang/test/TableGen/emit-diag-docs.td for examples of how it looks.

[AMDGPU] Refresh RegisterClassInfo after reserving WWM registers (#221849)
AMDGPUReserveWWMRegs reserves the VGPRs the WWM allocator picked for SGPR
spill lanes and clears the per-lane VGPR mask, but updates neither
MachineRegisterInfo nor the shared RegisterClassInfo. RegAllocBase
re-freezes the reserved set, but owns its RegisterClassInfo by value, so
only its private copy is refreshed, and a later user of the analysis is
offered an allocation order that still lists the reserved register.
AMDGPURewriteAGPRCopyMFMA became such a user in #216510: its spill slot
elimination assigned that register, which asserts in VirtRegMap and, in a
build without assertions, silently clobbers the spilled SGPRs. #216510 was
reverted in #221749; this is a prerequisite for relanding it.
Update MRI and the analysis at the end of the pass, as SIPreAllocateWWMRegs
already does, after clearPerLaneVGPRAllocMask() since the mask is itself an
input to getReservedRegs().
AI-assisted.

[libc][unistd] Support _SC_GET(GR|PW)_R_SIZE_MAX in sysconf. (#222135)
* Add support for POSIX-specified `_SC_GETGR_R_SIZE_MAX` and
`_SC_GETPW_R_SIZE_MAX`
constants used as arguments to `sysconf` function;
* Return -1 for these values - they provide "initial size" for
user-supplied buffers passed to `getgr*` and `getpw*`
functions, but there's no real maximum limit imposed by the LLVM-libc
implementation, and user might provide a
size they can, and rely on `ERANGE` return values if the chosen size
ended up being too small for pwd/group entries.
* Add unit test coverage, and update the unit test to use proxy headers
instead of system-provided `<unistd.h>`.
Also, properly test errno values returned by `sysconf`.
This fixes one of the remaining blockers for building Clang against
LLVM-libc (https://github.com/llvm/llvm-project/issues/97191)

[Github] Match backend:NVPTX files outside llvm/ (#221968)
The backend:NVPTX labeler rules are anchored to the llvm/ subtree (every
glob starts with llvm/**), so NVPTX/NVVM-related files elsewhere in the
tree never get the label. In particular, ClangIR's lowering under clang/
touches NVPTX code but the PR is not tagged backend:NVPTX.
This drops the llvm/ prefix so the patterns match anywhere in the tree.

[MLIR][Transform] Enable strict property assembly format (#217290)
Enable strict property assembly format mode for the Transform dialect
and its extensions. Bind transform operation options directly in
declarative assembly formats so strict parsing does not rely on fallback
handling.
Update transform dialect, extension, and transform-driven tests to use
the direct property spelling.

[Clang][Sema] Promote pointers to common address space in pointer subtraction (#217341)
fixes #216804
## Summary
This PR fixes pointer subtraction between pointers with different but
overlapping address spaces (e.g., `private` and `generic` in
OpenCL).
Previously, when subtracting a private pointer from a generic pointer on
AMDGPU:
- The private pointer (AS5, 32-bit) was converted directly to i32 via
`ptrtoaddr`
- The generic pointer (AS0, 64-bit) was converted to i64 via `ptrtoaddr`
- This resulted in incorrect comparison of 32-bit vs 64-bit values
Now, pointers are first promoted to the composite (superset) address
space using `addrspacecast` before the subtraction. This
mirrors how the conditional operator (`?:`) already handles mixed
address space pointers.
## Test plan
- `clang/test/CodeGenOpenCL/size_t.cl` updated and passes
- Verified generated IR shows correct `addrspacecast` before `ptrtoaddr`
for AMDGCN and SPIR targets

a copy of linux kernel headers.

[AArch64][CMPBR] Fix splitting of CBB/CBH instructions into ext + cmp (#221112)
We falsely split CBB/CBH instructions by explicitly extending the
second register operand instead of the first one, leading to the
following, wrong codegen:
cbh $wn, $wm, cc, trgt => sxth $wt, $wm
cmp $wn, $wt, cc, sxth
Correct is
cbh $wn, $wm, cc, trgt => sxth $wt, $wn
cmp $wt, $wm, cc, sxth
since cmp with extended register extends it's second, not its first
operand.

[libc++][NFC] Remove `optional::__get` (#217218)
Internal communicating functions `optional::__get` can be superseded by
either `value`, `operator*()`, or direct use of data member. Even though
`value()` is checked, checks are already performed before internal calls
to it, so compilers should be able to remove duplicated checks.
It is intended to use `opt.value()` instead of `*opt` to avoid undesired
argument-dependent lookup.

user's threads, so everything needing the team size computes
`BlockSize - WarpSize`: the device runtime's `getMaxTeamThreads`, and
the state
machine OpenMPOpt builds. The bound written into the kernel was the
program's
`thread_limit` exactly, so on gfx90a `thread_limit(4)` launched a block
of 4
threads and the team size came out as `4 - 64`. That subtraction is
unsigned, so
the runtime saw four billion workers rather than none: the parallel
region never
ran, and on current trunk the launch dies with a memory access fault.
Any
`thread_limit` below one warp was affected, so anything under 64 on a
wave64
target.
Add the warp where the bound is written, in `createTargetInit`, for
generic mode
only, so `thread_limit(4)` writes 68 and the team gets its 4, clamped to
the
target's maximum work group size because an out-of-range bound is
dropped rather
than clamped. A fixed 64 is reserved rather than the target's own
wavefront: the
bound is only a ceiling, and the runtime still adds the real warp size
and
clamps to it, so the block that launches is unchanged. Where the warp is
narrower the ceiling is 32 too high, which costs the backend some
register
budget and nothing else; NVPTX with `thread_limit(20)` now gets
`maxntid=84`
where it would have got 52, and still launches 52.
The record-replay recorder, which wrote `thread_limit` as the largest
launch a
replay would accept, now records the larger block that was actually
launched.
`thread_limit_below_wavefront.c` is the reproducer, and the remaining
files are
regenerated clang and MLIR expectations.
## Testing
Tested on `main` at 68622e02c9e5: `clang/test/OpenMP`,
`mlir/test/Target/LLVMIR`
and `llvm/test/Transforms/OpenMP` give 2114 passed, 14 unsupported, 4
failed.
The four are `mlir/test/Target/LLVMIR/nvvm/tcgen05-mma-shared*`, which
fail on
`main` independently of this change: their RUN lines hand `llc` an
`-mxcoff-roptr` it only accepts on AIX.
`check-offload` on an MI210 has nothing failing: 1134 passed, 4
expectedly
failed, 363 unsupported, 12 skipped. That covers the new test,
`thread_limit_below_wavefront.c`, and the six `omp-kernel-replay` tests.

[AMDGPU] Do not freeze reserved registers in AMDGPUReserveWWMRegs (#222193)
Refreshing the shared RegisterClassInfo needs an up-to-date reserved set, but
freezing it into MachineRegisterInfo, as #221849 did, publishes it too early:
clearing the per-lane VGPR mask unreserves those registers, and LiveIntervals
does not extend a reserved register's unit ranges to its uses, so those uses
fail verification.
Take the set from TargetRegisterInfo instead. It is the same set, and the
register allocator still freezes it into MachineRegisterInfo itself.

[IR][DirectX] Drop IsTokenLike from `dx.*` target types (#222130)
We made the DirectX resource types "token-like" a while ago in order to
prevent transforms from moving them into PHIs and the like in ways that
made determining their provenance more difficult. However, there are
patterns in HLSL that can generate the problematic IR directly and we've
since implemented logic in `DXILResourceAccess` to handle such cases
anyway. Because of this, we aren't really getting any benefit from the
types being `IsTokenLike`, and in some cases we're working with
intermediate IR that doesn't actually pass the verifier.
Drop `IsTokenLike` from the `dx.*` types since it's no longer correct or
useful. I've updated the tests to use `amdgpu.stridemark` instead, and
slightly abused `llvm.ssa.copy` in order to manufacture SSA values of
that type. I had to drop the test that actually needed a load from a
value depending on the token-like type, as there just isn't really a way
for that to come up without the resource types.

[MemProf] Use NodeId to break ties deterministically in identifyClones (#222126)
In identifyClones(), ties between caller edges with identical allocation
types and matching clone candidates were previously broken by comparing
the first element of ContextIds (*A->ContextIds.begin() <
*B->ContextIds.begin()).
Because ContextIds is a DenseSet, its iteration order depends on hash
table
layout and bucket distribution, introducing non-determinism across
different
runs or architectures.
Replace this tie-breaker with caller NodeId (A->Caller->NodeId <
B->Caller->NodeId),
which provides a deterministic and stable ordering. Also apply
Callee->NodeId
in CalleeCallerEdgeLessThan for consistency.
Update tests whose remark or dump order depended on the previous
tie-breaker.
For tests that verify multi-clone greedy assignment behavior
(funcassigncloning*.ll),
reorder the input MIB contexts so caller NodeIds reproduce the visit
order
exercising the extra clone creation.

[BOLT][RISCV] Implement register analysis hooks (#220581)
This patch implements the RISC-V register-analysis hooks in
`RISCVMCPlusBuilder` that previously fell back to the unimplemented
base-class methods.
The `MCPlusBuilder` unittests fixture is also extended to create a
RISC-V binary context. New tests cover the flags-register result,
zeroing-XOR recognition, ABI register masks, general-purpose register
masks, and non-scavengeable registers. These hooks provide the
target-specific register information required by BOLT analyses and
transformations on RISC-V.
BTW, this is split out as a prerequisite fo LongJump pass implement for
RISCV.

[LLVM][AutoUpgrade] Support default args on undeclared multi-call upgrades (#216246)
When an `.ll` file contains multiple calls to an intrinsic without an explicit
declaration, only the first call is upgraded successfully, and the remaining
subsequent calls fail.
`LLParser` builds one temporary Function per call, so after the first
upgrade occupies the canonical name the later functions are uniquified
(eg. `llvm.foo.1`). The intrinsic ID was previously looked up using `F->getName()`,
which requires an exact name match. So, the uniquified names resolved to `not_intrinsic`,
causing the upgrade to return and the default arguments were not applied.
This patch fixes this issue by using the cached `F->getIntrinsicID()`,
which is set when the temporary function is created from the original name.
It also `rename(F)` before inserting the full declaration, so the temporary
function no longer occupies the canonical name.

[clang][test] Make new absurdly_big_struct test more targeted (#219897)
The previous version of `y()` used `c2[i]`, which can't be evaluated at
compile-time.
The emitted diagnostic depends on something calling
`ASTContext::getASTRecordLayout()` for `b`, which currently happens in
the constant evaluator. If the evaluator decides to evaluate `c2[i]`
before calling `getASTRecordLayout()`, the test fails since the
diagnostic is never emitted.
Fix this by simply using `c2[0]` instead.

When searching the documentation for LLVM for `llvm::sys::fs::status`,
only the version with file descriptor can be found because the
documentation is built on the UNIX host and the file handle version is
defined out.
In reality, file handle version is more portable and should be displayed
instead. On UNIX, these two functions have the same underlying type,
thus it shouldn't matter which one is declared, and both versions are
still available on Windows for compatibility.

Remove the default constructor of `outer-iterator::value_type` and make
the remaining constructor private (exposition-only), as required by LWG
4013.
Update the corresponding tests:
- `ctor.default.pass.cpp` and `ctor.iter.pass.cpp` are now deleted.
- `ctor.compile.pass.cpp` is added to verify `value_type` is not
default-constructible and its construction from iterator is not
available.
- Cases testing construction of `value_type` via `operator*` are moved
to `range.lazy.split.outer/deref.pass.cpp`.

[AMDGPU] Rework pseudo-scalar transcendental inline constant restriction handling (#208459)
The f16 pseudo-scalar transcendental instructions do not support inline
constants on gfx12. The existing handling of this restriction is
incomplete. It involves checking the
hasNoF16PseudoScalarTransInlineConstants function in the right places.
For the SIInstrInfo::isInlineConstant function, for instance, this has
led to a situation where some overloads respect the restriction and
others do not. This approach also relies on completely disabling the
folding of constant operands. The machine code emission does still use
the inline constant encoding if it encounters a suitable operand.
Introduce a new "noinline" operand type and use it for the instruction
variant that is used on gfx12. This does also enable the use of literal
constants.

[clangd] Place deduced return type hints after noexcept (#219829)
Deduced return type hints for functions and lambdas could appear before
a `noexcept` specifier, even though a trailing return type belongs after
the exception specification.
Use the end of the function type's local source range when it is
available. For lambdas without a function type location, keep the end of
the lambda introducer as a fallback.

[CIR] Reposition entry-block allocas ahead of control flow (#220496)
HoistAllocas returns early when an alloca was already in the entry
block, but being in the block is not the same as being ahead of the
control flow in it. The pass runs before FlattenCFG, which splits the
body at each structured control-flow op, so an alloca sitting after one
is left in a block that is no longer the entry block.
That matters because SROA only collects allocas from the entry block. An
alloca stranded behind a scope is invisible to it and never promoted, so
anything whose address it holds stays in memory.

[IR] Do not inherit ABI attributes from the callee (#207173)
Usually attributes that are missing on the call-site are inherited form
the callee instead. This is fine for optional optimization attributes,
but problematic for ABI-affecting attributes.
ABI attributes generally must be placed at the call-site as well,
because there is no callee to inherit from for indirect calls. Failing
to specify ABI attributes at the call-site generally indicates a bug.
The motivation for being stricter about this (apart from just being the
right thing to do) is to properly support cases where the attributes at
the call-site and the callee actually differ. Two examples I'm aware of
are:
* During cross-language LTO, it's possible to have one side use a `ptr`
argument and the other a `ptr byval(ptr)` argument. Both represent the
same ABI using different IR encodings, but you can't just inherit the
`byval` attribute from one to the other (because the byval case requires
an additional level of indirection in use of the argument).
* To fix our incompatibility with the x86-64 psABI, I believe we'll want
to do something like emit zeroext/signext at function returns and
call-site arguments only, so that we both don't assume incoming values
are zero/sign-extended, but still zero/sign-extend outgoing values. This
makes sure we still remain compatible with old Clang-generated object
files.
We've attempted to make a change like this previously, but ran into
substantial issues with missing call-site attributes on
compiler-inserted calls. The issue was particularly severe on s390x,
which requires zeroext/signext on more values than other architectures.
I believe that the situation here has improved a lot in the meantime,
with libcalls now inferring mandatory ABI attributes, and s390x also
using a noext attribute plus validation logic in the backend to detect
cases where the necessary attributes are missing.
-----
ABI attributes on call-sites must be queried using `hasABIParamAttr()`
and `hasABIRetAttr()` instead of `paramHasAttr()` and `hasRetAttr()`
now. Passing an ABI attribute to the latter two will result in an
assertion failure.

Add support for NSDI DebugScope, DebugNoScope and DebugInlinedAt (#218959)
Add support for NSDI
[DebugScope](https://github.khronos.org/SPIRV-Registry/nonsemantic/NonSemantic.Shader.DebugInfo.html#DebugScope),
[DebugNoScope](https://github.khronos.org/SPIRV-Registry/nonsemantic/NonSemantic.Shader.DebugInfo.html#DebugNoScope)
and
[DebugInlinedAt](https://github.khronos.org/SPIRV-Registry/nonsemantic/NonSemantic.Shader.DebugInfo.html#DebugInlinedAt).
DebugScope/DebugNoScope are region delimiters following the same region
rule as DebugLine/DebugNoLine. The two regions are tracked separately
because a DebugScope region could span several DebugLine regions, and
either can skip emission on a cache miss at different times.
DebugInlinedAt is not an region instruction, so it is emitted at module
scope. We allow recursive traversal when building them to support
chains.
The PR also adds a test showing a limitation in the DebugLine
deduplication that is at the DILocation pointer level which may lead to
duplicate opcodes.

[ADT] Give DenseMapPair its own members instead of a std::pair base. NFC (#221853)
std::pair declares a copy assignment operator, so it is not trivially
copyable. destroyAll and copyFrom therefore ask about KeyT and ValueT
separately. Hold first and second directly.
Conversion to std::pair is explicit; insert also takes a bucket, and a
converting constructor keeps range insert working across pair types.

[RFC][AMDGPU] Add BARRIER address space (#209746)
Add a new BARRIER address space that is used for global variables that
are used to represent the barrier IDs in GFX12.5.
These barrier addresses just have values corresponding 1-1 to barrier
IDs. They are still implemented on top of LDS, but the offsetting
happens during an addrspacecast to generic, not whenever the barrier GV
is used.
The motivation for this is to make the relation between LDS and barrier
GVs explicit in the compiler. It does add a bit more complexity, but
that complexity was already there, just hidden by pretending barrier GVs
were actual LDS.

[X86] Enable preferZeroCompareBranch() (#219919)
This makes CodeGenPrepare reorganize code such as:

%a = add i32 %x, -10
```
into
```
%a = add i32 %x, -10
%cmp = icmp eq %a, 0
%br %cmp, then, else
```
so that the zero-compare and branch gets lowered to a JCC based on the
flags from the arithmetic instruction.
This was already enabled for ARM, SystemZ and RISC-V, but seems a good
fit for X86 too, as mentioned in Issue #58636.

[VPlan] Record estimated branch probabilities on VPlan0 for cost modeling (#216172)
Update execution frequency/probability tracking in VPlan to also include
estimates from BFI, and use the information in VPlan for VPlan-based
cost computations, removing another remaining IR-based lookup.
We need to differentiate between estimated and concrete profile
information when annotating branches with information from BFI (using
custom !vplan.prof.estimated metadata instead of !prof) and track if a
computed frequency contains any estimates using an extra bool which is
also encoded in the metadata (so we do not synthesize !prof
for such frequencies during codegen).
The new code should only request BFI if needed, and compile-time impact
should be in the noise:

[lldb] [unittests] Cover what the memory cache reads from the inferior (#221015)
`MemoryCache`'s tests checked how many bytes a read returned, never
which requests the cache made to get them, so a change to the request
shape could not fail a test. Add four tests over the request log
`DummyProcess` now keeps.
Two assert what the cache sends: `TestReadRequestShape` checks the
address and size of every request, and `TestReadRangesFromCaches` checks
that a range the cache already holds is served without reaching the
inferior.
`TestFlushAtTheTopOfTheAddressSpace` pins `Flush`'s current behavior at
the wrap, not correct behavior. When a flushed range wraps past
`UINT64_MAX`, `Flush` counts cache lines only from the start of the
range to the top of the address space, never the lines the wrapped
portion covers between address 0 and the range's end. This bug predates
this change; the following cache-partition change fixes it, and this
test's assertion that address 0 survives the flush will need to flip
once
that lands.
`TesetMemoryCacheRead` gains one assertion, that a line whose reply
falls short leaves the error alone, next to the two requests it already
checks.
Also add a `CacheTestProcess` helper and use it in the seven cache
tests, so each states its setup in two lines rather than thirteen, and
expose the L2 map next to L1 for assertions.

Remove the in-place mutation loop and return a new select node. The DAG
combiner visits each select independently and `getSetCC` CSEs the
inverted condition so all commuted selects share it.

[X86] Compress masked VPBLENDM using VBLENDV (#221838)
Fixes #221678.
This extends the X86 EVEX compression pass to recognize compatible
`VPMOVD2M/VPMOVQ2M + VPBLENDMD/VPBLENDMQ` patterns and replace them with
the corresponding VEX `VBLENDVPS/VBLENDVPD` instruction when the mask
width and element granularity match.
For example, the reported AVX-512 sequence:
```asm
vpslld $31, %xmm0, %xmm0
vpmovd2m %xmm0, %k1
vpblendmd %xmm1, %xmm2, %xmm0 {%k1}
```
is reduced to:
```asm
vpslld $31, %xmm0, %xmm0
vblendvps %xmm0, %xmm1, %xmm2, %xmm0
```
The fold is restricted to compatible producer/consumer pairs.
Mixed-width or mixed-element-granularity cases such as
`VPMOVD2MZ128 + VPBLENDMQZ256` are intentionally left unchanged.
The MIR coverage includes:
- 128-bit and 256-bit dword/qword positive cases.
- An incompatible-width negative case.
- Kill/liveness preservation for the reused vector mask.
The existing `avx512-regcall-NoMask.ll` codegen checks are also updated
to reflect the optimized `VBLENDVPS` sequence produced by this fold.
Local validation includes:
- `compress-evex-vpmov-blendv.mir`
- `compress-evex-vpmov-kill.mir`
- `avx512-regcall-NoMask.ll`
- `compress-evex-sign-mask.mir`
- `evex-to-vex-compress.mir`
- `bitcast-sign-mask.ll`
AI-assisted tools were used during investigation and development.
The resulting changes were reviewed, modified, validated, and tested by
me.

[lldb] Match frame recognizers by function when the frame has no symbol (#222060)
A frame can have a function without having a symbol: a PE/COFF image
built with DWARF carries no symbol table at all, so `symctx.symbol` is
null on Windows while `symctx.function` resolves fine from the debug
info. `GetRecognizerForFrame` bailed out on `!symbol`, so no frame
recognizer ever matched there.
Fall back to the function's start address when there is no symbol. The
symbol still wins when both are present, so this is a no-op on
ELF/Mach-O.
This fixes `TestFrameRecognizerStepThrough.py`.

[BOLT][RISCV] Fix AUIPC/JALR call rewriting (#216882)
This builds on the RISC-V decoder support from #217550 and the BOLT
target symbolizer and GOT relocation handling from #217944, both of
which are now merged.
`R_RISCV_CALL` and `R_RISCV_CALL_PLT` cover an AUIPC/JALR pair, but BOLT
treated them as four-byte relocations and decoded only the AUIPC
immediate. Read both instructions and combine their signed high and low
immediates so relocated call targets retain the low 12 bits.
LTO can also leave linker-resolved intra-section AUIPC/JALR calls
without relocations. On RV64, recognize standard call and tail-call
pairs during disassembly, reconstruct the target (including JALR
target-bit clearing), and attach an exact entry-point symbol before
function reordering. Alternate link-register preservation is provided by
the merged #218408.
This follows the RISC-V Unprivileged ISA sections on AUIPC and JALR:
https://docs.riscv.org/reference/isa/v20260120/unpriv/rv32.html
It also follows the RISC-V ELF psABI procedure-call relocations:
https://riscv-non-isa.github.io/riscv-elf-psabi-doc/#_relocations
Tests cover relocation-backed calls, relocation-free RV64 calls and tail
calls, exact function entry points, signed offsets, JALR target-bit
clearing, and rejection of near matches.
Validation:
- Rebuilt `llvm-bolt`, `llvm-mc`, `llvm-objdump`, `llvm-readelf`, and
`lld`.
- All 658 tests in `bolt/test/RISCV` and `llvm/test/MC/RISCV` pass on
current `main`.
**Scope:** Relocation-free recovery is intentionally RV64-only. RV32
XLEN-wrapped target arithmetic remains out of scope. Symbolizer
infrastructure and GOT correctness are provided by #217944 rather than
this PR.

[MLIR][XeGPU] Restrict XeGPUPropagateLayout analysis scope (#221793)
This PR prevents concurrent access to traversal and mutation of the
shared IR by restricting the walk scope to determine program order
within each gpu.module.
Previously, although the pass is scoped to a single gpu.module, this
walk climbs all the way up to the enclosing top-level builtin.module and
traverses the entire module — including sibling gpu.modules. When there
is multiple gpu.modules, it causes concurrent traversal and mutation of
the shared IR and eventually leads to a segfault.

[fir][aa] Add opt-in cache for use by fir `AliasAnalysis` clients (#221973)
Adds `AliasAnalysisRecursiveEffectsCache`, an opt-in cache that memoizes
per-operation read/write summaries so that `getModRef` on an operation
with `HasRecursiveMemoryEffects` does not re-walk its nested regions on
every query.
This is independent of the `getSource()` memoization added separately:
that one is keyed on (value, flags) and answers "what memory does this
value refer to", while this one is keyed on the operation and answers
"what does this operation and everything nested in it read and write".
LICM enables both, since it only hoists pure-read ops and so invalidates
neither.

the reusing gathers' current costs is not worse than re-emitting those
gathers without it. Exclude splat roots from the main trimming loop.

[NFC][BOLT][RISCV] Fix call-relocation-pair test after NOP removal (#222308)
The test introduced by https://github.com/llvm/llvm-project/pull/216882
expects temporary NOPs from FixRISCVCalls in the emitted binary.
https://github.com/llvm/llvm-project/pull/221965 marks those NOPs for
removal, causing FileCheck to match trailing alignment padding instead
of the rewritten calls.
This caused the call-relocation-pair.s failure on
[bolt-aarch64-ubuntu-dylib, build
6378](https://lab.llvm.org/buildbot/#/builders/216/builds/6378).
Check emitted calls independently of the temporary NOPs and verify the
forward-call target symbols. Preserve the intermediate-pass NOP checks.
Validation: all five test RUN commands pass with local BOLT builds that
retain and remove the temporary NOPs. The original test reproduces the
reported FileCheck failure with the NOP-removing build.

[MLIR][Remark] Import LLVM optimization remarks into the remark engine (#222300)
Collect LLVM side of remarks with MLIR's remark infra.
LLVM passes emit their own [optimization
remarks](https://llvm.org/docs/Remarks.html) and MLIR has own. This PR
bridges MLIR and LLVM remarks.
`ModuleToObject` installs a `remark::LLVMToMLIRDiagnosticHandler` on the
`llvm::LLVMContext` it compiles with, which imports these remarks into
the remark engine: the category is the LLVM pass name prefixed with
`llvm-`, the LLVM remark name becomes the name, the message is stored
under the `Remark` argument and the structured LLVM arguments are copied
as metrics. The remark filters therefore select LLVM remarks by pass
name, and `llvm-.*` selects all of them.

This implements a cut-down version of the LLVM equivalent (in
llvm/include/llvm/ExecutionEngine/Orc/Shared/Mangler.h): SymbolNameSpec
pairs a name with a kind (assembly, C). Mangling functions
(withMangledNameDo, mangledCopy) apply mangling to SymbolNameSpecs based
on the symbol name kind.
These utilities will be used to report symbols (e.g. controller
interface symbols) in the platform's native mangling, so that linking
against them requires no special handling.

[libc++] Opt `std::*set` out of map key extraction optimization (#220452)
PR #154512 (relanded by #155565) removed `__can_extract_map_key`, which
had a blanket opt-out for `std::*set`s. The new logic does not have that
opt-out, leading to `std::set`s being incorrectly constructed.
The new regression tests demonstrate this, but essentially the idea is:
1. Have `std::set<T> foo;`
2. Call `foo.emplace(some_t,
arg_that_influences_comparisons_or_hashes);`
3. The emplace will internally search using `some_t` as the key, *not*
`T(some_t, arg_that_influences_comparisons_or_hashes);`
This opts out `std::*set` from this optimization to match previous
behavior.
Tests and fix were produced by an LLM. I reviewed them and they seem
reasonable to me, though I don't have a strong background in libc++
testing conventions.
(Credit to Deva S, our partner who tracked this down. Unfortunately I
don't know his GH handle)

This patch adds a second entry point to the C LTO API that takes a
triple and passes it along.
Bump `LTO_API_VERSION`.

[Clang] Skip invalid fields when synthesizing defaulted comparisons (#221570)
Fixes #194605
`CheckFieldDecl` already rejects `int [[clang::address_space(1)]] i;`
and marks the field invalid, but `DefaultedComparisonVisitor` still
visited it when synthesizing the defaulted `operator==`.
`BuildFieldReferenceExpr` then tripped the
`!MemberQuals.hasAddressSpace()` assertion. Both
`__is_trivially_equality_comparable(S)` and a plain `a == b` reach that
path.
`visitSubobjects` now skips invalid fields, the same way
`SpecialMemberVisitor` and the copy-assignment synthesis already do.
That covers the analyzer and the synthesizer together, and the assertion
stays in place since it still holds for valid code.

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

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

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

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

language and for `S_FRAMEPROC` there are bits in the middle representing
the frame pointer registers for variables and parameters.
In both cases, the values of the enums were not present in the generated

Mapping this in YAML is a bit complicated, because we can't give
`yaml::IO` a reference to the flags. I used local variables and a check
if we're reading to re-assemble the flags.

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

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

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

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

[SDAG][ComputeNumSignBits] Look through undefined high bits for EXTRACT_VECTOR_ELT in a BUILD_VECTOR (#218099)
If we have a `BUILD_VECTOR(EXTRACT_VECTOR_ELT()...)` where the

`BUILD_VECTOR` is again truncating those bits, then we can just look
through the extract and call `ComputeNumSignBits` directly on the parent
vector.
Ideally, when the caller is truncating the value, it would be nice for
`ComputeNumSignBits` to have the ability to ignore high bits we don't
care about.

Neither old path resolves at `main`; both replacements do.

`mlir/docs`, `lld/docs`, `libcxx/docs` and `flang/docs` against the

remaining candidates are correct in context and were left alone. I have
reviewed and understood the change and take responsibility for it.

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

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

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

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

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

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

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

[flang][FIRToMemRef] Do not peel storage-association views (#222376)
After #215402, peelZeroOffsetViews walked through fir.convert that
changes the pointee type (e.g. !fir.ref<complex<T>> → !fir.ref<T>).
Load/store then indexed the parent array and converted the value, which
is wrong for Fortran storage association: it fails verification
(memref.store / illegal fir.convert) or silently changes bits (sitofp /
fpext).
Stop peeling when the accessed element type changes. Marshal the typed
view as a rank-0 memref of the dummy type. Same-type wrappers
(fir.declare, ref<T> → ref<T>) still peel to fir.array_coor.

The unsigned no-wrap region of an add with a constant operand has

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

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

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

[flang] Collapse execution-part statement error flood into one error message (#220988)
An unrecognizable statement in the execution part of a source file
produced one "expected 'KEYWORD'" error for every possible statement
because each execution-part-construct alternative failed at the same
source position and the alternative combinator merges the messages of
same-position ties.
Wrapped the keyword-led alternatives in `withMessage` so that when none
of them matches a token, the flood is discarded in favor of a single
"expected an executable statement" diagnostic.
This fixes the problem identified in Issue:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

clang static libraries (the Registry members and accessors come back)
and against MSVC-mangled test objects; Firefox's Windows clang-plugin
and mozsearch builds link and run against a clang.exe built with it.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

This handles 2 additional cases when Start < RHS:
* Stride is known power-of-2:
* Start == Stride and Start == Stride -1.
The patch includes a mechanical change to move up the existing
MayAddOverflow with comments, and clarifies the name to

[lldb] Move most PDB shell tests to NativePDB (#222370)
I plan to remove the DIA PDB plugin before the 24 release - we switched
the default to the native one in 22. To avoid losing test coverage in
the process, this moves the SymbolFile/PDB tests to
SymbolFile/NativePDB. They were already running with both plugins. In
some cases, we set `env LLDB_USE_NATIVE_PDB_READER=1`, which I flipped.
The remaining shell tests are:
- `func-symbols.test`: Has a duplicate in NativePDB with different
checks, because the two plugins don't create identical types (see
comment in test)
- `udt-layout.test`: Also has a duplicate with different checks, because
the two plugins show the base classes in a different order.
Other than that, there's also a [unittest for
PDB](https://github.com/llvm/llvm-project/blob/2de38b4861ed4a7be7ddd42fc803e91d1fe81b14/lldb/unittests/SymbolFile/PDB/SymbolFilePDBTests.cpp).
I'm not sure what we should do about it. Looking over the tests there,
most of these are already covered by the shell tests.

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

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

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

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

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

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

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

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

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

[libc] Enable full-build code coverage (#221802)
Extended LIBC_ENABLE_COVERAGE to support LLVM_LIBC_FULL_BUILD=ON and
added the LIBC_ENABLE_COVERAGE_MCDC CMake option for MC/DC coverage.
This enables developers and CI pipelines to measure source-level and
MC/DC coverage directly on hermetic tests in full-build configurations
without relying on the host C library.
Updated add_libc_hermetic in LLVMLibCTestRules.cmake to link hermetic
tests with -noprofilelib, -u__llvm_profile_runtime, and compiler-rt's
profiling library. Replaced internal entrypoint objects in
link_object_files with public entrypoint objects for the C functions
referenced by libclang_rt.profile.a.
Added calloc and __errno_location to HermeticTestUtils.cpp to satisfy
remaining freestanding profiling runtime dependencies. Updated
libc/docs/dev/code_coverage.md with full-build instructions.

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

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

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

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

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

[CIR][NFC] Reduce the dialects referenced by cir-lsp-server to minimum (#222131)
This is 1 of 2 patches that build on the work of others, and reduces the
list of dialects to just those in CIR + a handful of others. Between
this, 1 other commit, and the existing patches proposed by others, we
reduce the 'overhead' of the CIR build to +30%.
AI Disclaimer: Claude came up with this and the list. I'm not sure it is
correct, but we pass all tests.

Due to this test running with verbosity turned up, an early 'Report'

macOS versions the interceptor's call to printf was attempting to
allocate before the allocator was initialized - leading to a crash.
This patch instead uses snprintf to a stack allocated buffer in order to
avoid allocating in the interceptor.

The intrinsics lower to dedicated `PMACC_HALVES_*` SelectionDAG nodes
rather than an `add` of plain products, ensuring instruction selection
does not depend on DAGCombine folding. On RV32, the word forms
accumulate into a GPR pair via new `WMACC`, `WMACCU`, and `WMACCSU`
nodes.
Also add corresponding Clang builtins and wrappers in

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

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

[lldb][Fortran] Add TypeSystemFortran files (#218016)
This PR adds the foundational TypeSystemFortran class. To satisfy the
compiler, it implements all required pure virtual functions from the
base TypeSystem class as stubs (returning nullptr or 0).
Changes:
- Adds the TypeSystemFortran class.
- Provides stub implementations for all inherited pure virtual
functions.
Part of the Add Fortran support to LLDB GSoC 2026 project.
Relates to #109119.

[mlir][LLVM] Split out the dialect declaration (NFC) (#222782)
Move LLVMDialect to a declaration header that retains its attribute and

Expose the Arith dialect, attributes, and interfaces without importing

users avoid parsing the operation umbrella and its dependencies.
Across three controlled serial rebuilds of five dialect-only TUs, median

from 7.40s to 5.85s (-20.946%). Across three -j16 rebuilds of 97 support

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

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

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

This change extends the LLVM ABI library's VectorType to be able to
describe SVE types and updates Clang's QualTypeMapper to map them.
The AArch64 target info class in the ABI library is still a work in
progress. It will continue to report "not yet implemented" for function
signatures involving SVE types. This change is a neceasary prerequisite
for correctly handling them or correctly deferring handling of these
specific types.

[lld][MachO] Add `--warn-missing-subsections-via-symbols` flag (#221464)
This change introduces:
* `--warn-missing-subsections-via-symbols`: Warns when an input object
file with non-empty sections is missing `MH_SUBSECTIONS_VIA_SYMBOLS`.
* `--no-warn-missing-subsections-via-symbols`: Disables the warning
(default).
Also adds documentation and lit tests.
Object files missing `MH_SUBSECTIONS_VIA_SYMBOLS` can prevent
dead-stripping and subsection splitting.
We have seen a number of cases where we are compiling assembly, and this
allows us to track them down.

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

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