[UnsafeBufferUsage][SSAF] Change -Wunsafe-buffer-usage API for SSAF-based analysis
Change -Wunsafe-buffer-usage API to match `Stmt`s instead of `Decl`s.
It is up to clients of the API to determine how to traversal a
`Decl`. In this change, the client is SSAF-based
UnsafeBufferUsageExtractor.
[SSAF][Analyses] Add an AST visitor for the contribution model
Add an AST visitor that respects the contribution model and will be
shared across SSAF analyses.
[MLIR][Python] Migrate `result(infer_type=True)` to a new field specifier (#191849)
Currrently the signature of `result(..)` is:
```python
result(*, infer_type: bool = False, default_factory: Callable[[], Any] | None = None, kw_only: bool = False) -> Result
```
so when users use `result(infer_type=True)`, the type checkers will
still get `kw_only=False` (from the signature), but actually the
`kw_only` should be `True` (it should follow the value of `infer_type`).
users can use `result(infer_type=True, kw_only=True)` but it's
unnecessarily verbose.
So it may introduce an incompatibility when we start to use
`dataclass_transform`. currently it's fine because we just don't use
`dataclass_transform`. But when we use, we may require a breaking
change.
This PR migrates such use to a new field specifier named
`infer_result()`.
Revert "[libclc][CMake] Use clang/llvm-ar on Windows (#186726)" (#191745)
This reverts commit 4abb927bacf37f18f6359a41639a6d1b3bffffb5.
The code is not needed since 121f5a96ff38 because the C compiler is now
always just-built clang in in-tree build. In addition, CMAKE_AR is
llvm-ar and CMAKE_RANLIB is llvm-ranlib.
[AMDGPU] Add object linking support for LDS and named barrier lowering in the middle end
This is the first patch in a series introducing object linking support for
AMDGPU.
This PR adds the -amdgpu-enable-object-linking flag to enable object linking in
the backend. It also updates the AMDGPULowerModuleLDSPass and
AMDGPULowerExecSync passes to support lowering LDS and named barrier globals
when object linking is enabled.
[AMDGPU] Preserve metadata in all barrier lowering paths (#191916)
Extend copyMetadata to every call-to-call replacement in
AMDGPULowerIntrinsics, not just the single-wave s_barrier →
wave_barrier path. This covers:
- s_cluster_barrier → wave_barrier (single-wave)
- s_cluster_barrier → signal_isfirst + wait + signal + wait (multi-wave)
- s_barrier → signal + wait (split barriers)
Add GFX11 and GFX12 RUN lines and test functions for all lowering
paths to verify metadata preservation.

[HWASan] Add hwasan-tag-bits flag (#191088)
This can be used to make sure the stack tagging does not use the top bit
of
the pointer. This is useful when HWASan is used in combination with
signed-integer-overflow detection. Some code uses arithmetic on intptr_t
that overflows for sufficiently large pointers.
[SSAF][UnsafeBufferUsage] Remove UnsafeBufferUsageExtractor.h
- Removed UnsafeBufferUsageExtractor.h
- Registered UnsafeBufferUsageExtractor
- Changed unit tests to enable the extractor with `HandleTranslationUnit`
- Fixed bugs in `UnsafeBufferUsageExtractor::HandleTranslationUnit`
