[lldb] Fix bytecode.test (#184903)
Follow up to #184714.
There are some other latent bugs here inside the formatter, but for now
this puts the test in a working state.
[flang] Reject PARAMETER constants in NAMELIST groups (#178960)
The Fortran standard does not allow `PARAMETERS` within a
`namelist-group-object`, it should only allow variables. An error should
be emitted when a `PARAMETER` is found within a `namelist-group-object`.
Fixes: #178955
[CIR][AArch64] Add missing lowerings for vceqz_* Neon builtins (#184893)
Implement the remaining CIR lowerings for the AdvSIMD (Neon)
`vceqz{|q|d|s}_*` intrinsic group (bitwise equal to zero).
The `vceqzd_s64` variant was already supported; this patch completes
the rest of the group [1].
Tests for these intrinsics are moved from:
* test/CodeGen/AArch64/neon-misc.c
to:
* test/CodeGen/AArch64/neon/intrinsics.c
The implementation largely mirrors the existing lowering in
CodeGen/TargetBuiltins/ARM.cpp.
`emitCommonNeonBuiltinExpr` is introduced to support these lowerings.
`getNeonType` is moved without functional changes.

iwx: Fix 32-bit compilation
- Avoid shifts wider than integer types, by wrapping the corresponding
checks into '#if __SIZEOF_SIZE_T__ > 32' blocks. 'bus_addr_t'
currently has the same width as 'size_t' on all architectures (and
this is not going to change for 32-bit architectures).
- Use appropriate printf(3) format for 'wk_keytsc'.

[LoopFusion] Correction in the comments (NFC) (#184689)
The comments in the code should have been updated following the change

that issue.
[docs] Add exception to AI tool policy for Bazel build fixer (#183408)
The Bazel RFC concluded earlier this month:
https://discourse.llvm.org/t/rfc-ai-assisted-bazel-fixer-bot/89178/93
I felt the best way to document this decision was to incorporate it into
this policy document.
[flang][OpenMP] Implement utility to locate OmpClause in ODS, NFC (#184866)
Simplify looking for a specific clause in OmpDirectiveSpecification.
This is alternative to DirectiveStructureChecker::FindClause for when
the internal checker structures have not yet been updated in the AST
traversal.

[flang][openacc] Relax semantic check on cache directive (#184887)
The specification doesn't really forbid the colon notation to be used to
specify the full array. Reference compiler accepts this and our lowering
can already handle it.

I found that the `SupportedRoundMode` pattern for true16 mode is removed

back in this patch and add gfx11 to the test which runs true16 mode

[flang][acc] Handle ViewLike ops with OutlineRematerializationOpInterface in OffloadLiveInValueCanonicalization (#184218)
`fir::ConvertOp` implements both `ViewLikeOpInterface` and
`OutlineRematerializationOpInterface`. `fir.convert` is also used for
ptr-to-int conversions like `(!fir.ref<i32>) -> i64`. That is not really
a "view" — it converts a pointer to an integer — but
`ViewLikeOpInterface` is still attached, so `getOriginalValue` traces
through it to the underlying value.
When the underlying value is not a rematerialization candidate (e.g.,
`fir.alloca`, a block argument, or a `fir.call` result),
`isRematerializationCandidate` returns false and the `fir.convert` is
left as a live-in. This prevents `ACCImplicitData` from tracing back to
the original pointer to create the data mapping.
This PR:
1. Registers `fir::ConvertOp` with
`OutlineRematerializationOpInterface`.
2. Adds a fallback in `isRematerializationCandidate`: when the traced

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

[mlir][acc] Add acc.compute_region and acc.par_width operations (#184864)
Introduce two new codegen operations to the acc dialect that model GPU
compute region execution and parallel launch configuration:
- acc.par_width: specifies a parallel dimension.
- acc.compute_region: wraps a region of code for GPU execution,
capturing
launch configuration (from acc.par_width results) and input values as
block arguments.
These operations bridge the gap between high-level OpenACC compute
constructs (acc.parallel, acc.kernels, acc.serial) and gpu.launch. The
passes that do these transformations will soon follow.

[CIR] Add support for delete cleanup after new operators (#184707)
This adds support for calling operator delete when an exception is
thrown during initialization following an operator new call.
This does not yet handle the case where a temporary object is
materialized during the object initialization. That case is marked by
the "setupCleanupBlockActivation" diagnostic in deactivateCleanupBlock
and will be implemented in a future change.
