[mlir][LLVM] Fix unsupported FP lowering in `VectorConvertToLLVMPattern` (#166513)

2025-11-05T12:24:59+00:00

Fixes a bug in `VectorConvertToLLVMPattern`, which converted operations
with unsupported FP types. E.g., `arith.addf ... : f4E2M1FN` was lowered
to `llvm.fadd ... : i4`, which does not verify. There are a few more
patterns that have the same bug. Those will be fixed in follow-up PRs.

This commit is in preparation of adding an `APFloat`-based lowering for
`arith` operations with unsupported floating-point types.

[mlir] Dialect Conversion: Add support for post-order legalization order (#166292)

2025-11-05T12:04:32+00:00

By default, the dialect conversion driver processes operations in
pre-order: the initial worklist is populated pre-order. (New/modified
operations are immediately legalized recursively.)

This commit adds a new API for selective post-order legalization.
Patterns can request an operation / region legalization via
`ConversionPatternRewriter::legalize`. They can call these helper
functions on nested regions before rewriting the operation itself.

Note: In rollback mode, a failed recursive legalization typically leads
to a conversion failure. Since recursive legalization is performed by
separate pattern applications, there is no way for the original pattern
to recover from such a failure.

[CIR] Add support for storing into _Atomic variables (#165872)

[clang-tidy][doc] add more information in twine-local's document (#166266)

2025-11-05T11:25:53+00:00

explain more about use-after-free in llvm-twine-local
add note about manually adjusting code after applying fix-it.
fixed: #154810

[clang][bytecode] Remove dummy variables once they are proper globals (#166174)

2025-11-05T11:15:48+00:00

Dummy variables have an entry in `Program::Globals`, but they are not
added to `GlobalIndices`. When registering redeclarations, we used to
only patch up the global indices, but that left the dummy variables
alone. Update the dummy variables of all redeclarations as well.

[libc][math] Disable `FEnvSafeTest.cpp` if AArch64 target has no FP support (#166370)

2025-11-05T11:14:02+00:00

The `FEnvSafeTest.cpp` test fails on AArch64 soft nofp configurations
because LLVM libc does not provide a floating-point environment in these
configurations.

This patch adds another preprocessor guard on `__ARM_FP` to disable the
test on those.

[clang][bytecode] Print primitive arrays in Descriptor::dumpFull() (#166393)

2025-11-05T10:52:59+00:00

And recurse into records properly.

[BOLT][AArch64] Fix search to proceed upwards from memcpy call (#166182)

2025-11-05T10:51:31+00:00

The search should proceed from CallInst to the beginning of BB since X2
can be rewritten and we need to catch the most recent write before the
call.

[clang] Delete duplicate code in sourcemanager (#166236)

2025-11-05T10:45:32+00:00

Now that the `SourceManager::getExpansionLoc` and
`SourceManager::getSpellingLoc` functions are efficient, delete
unnecessary code duplicate in `SourceManager::getDecomposedExpansionLoc`
and `SourceManager::getDecomposedSpellingLoc` methods.
