[Flang][OpenMP] Extend omp requires detection in Bridge.cpp (#188106)
Currently, we do not check the module for requires directives, which
means we'll miss these and not set them on the OpenMP module.
Otherwise, due to the first come first serve method we currently check
the symbols, there is certain formats that would mean the compiler would
miss that a user had specified requires somewhere in the module. This is
partially but not fully avoided by the Semantics layer pushing the
requires on to the top most PFT symbol, as it is entirely possible to
create a legal Fortran program where you could have two or more of these
(e.g. module and main program in one file, standalone funcitons
intermixed with modules or main program). Some examples of this are
shown in the added Fortran test. This PR opts to resolve it by gathering
all of the relevant symbols and processing them.
Also removed gathering from BlockDataUnit as I don't think these symbols
ever get the requires applied.
[mlir][sparse] add GPU num threads to sparsifier options (#189078)
This change adds a `gpu-num-threads` option to the sparsifier. This
allows users to specify the number of threads used for GPU codegen,
similar to the `num-threads` option in the `-sparse-gpu-codegen` pass.
[SelectionDAG] Assert on non-FP operand to `computeKnownFPClass` (#189752)
Assert correct usage of `computeKnownFPClass` or users (i.e.,
`isKnownNeverNaN`).
[DA] factor out repetitive code in GCD test (NFCI) (#189461)
The logic for recursively investigating the source and destination
AddRecs in GCD test is the same and can be factored out.
Fully disable `preserve_none` under ASan (#190001)
This crashes Clang 19, 21, and 22 on x86-64 that I've tested and I don't
have a ready-to-test build of any other versions but it seems much safer
to just disable for now.
[scudo] Ensure that reallocate copies everything
getUsableSize returns the actual capacity of the underlying block, which
may be larger than the size originally requested by the user. If the
user writes data into this extra space accessible via getUsableSize and
subsequently calls reallocate, the existing implementation only copies
the original requested number of bytes. This resulted in data loss for
any information stored beyond the requested size but within the usable
bounds.
[flang] Update Flang Extension doc to reflect previous change (#188088)
Update Flang Extension doc to remove note about a warning that was
removed in a previous PR (PR #178088). It is an oversight that this doc
change was not made in that previous PR. The oversight was only recently
discovered and has led to this PR.
Revert "[flang] Preserve UseErrorDetails in module files (#189423)" (#189997)
This reverts commit fce3a66f5e2f247890c57ac01a2c9847358c0f27. It broke a
Fortran application in our in-house testing.
[SelectionDAGBuilder] Only check VPCmp for NaNs in fp comparisons (#189749)
`getFCmpCodeWithoutNaN` should only be used for FP comparisons (which is
also the only context in which `isKnownNeverNaN` makes sense).
[CIR][MLIR][OpenMP] Enable the MarkDeclareTarget pass for ClangIR (#189420)
This patch enables the MarkDeclareTarget for CIR by adding the pass to
the lowerings and attaching the declare target interface to the
cir::FuncOp. The MarkDeclareTarget is also generalized to work on the
FunctionOpInterface instead of func::Op since it needs to be able to
handle cir::FuncOp as well.

[VPlan] Strip dead code in isUniformAcrossVFsAndUFs (NFC) (#189687)
Checking a VPInstruction for scalar-cast is equivalent to checking
opcode against Instruction::isCast via preservesUniformity.
[flang] fix a dangling else in allOtherUsesAreSafeForAssociate (#189748)
Fix a dangling if condition in allOtherUsesAreSafeForAssociate that
caused isBeforeInBlock to be called even when instructions were known to
not be in the same block, triggering an assertion. The condition was
changed to else if and added brackets.

[VPlan] Avoid unnecessary BTC SymbolicValue creation (NFC) (#189929)
Don't unnecessarily create a backedge-taken-count SymbolicValue. This
allows us to simplify some code.
[flang][OpenMP] Remove qualification from evaluate::SymbolVector, NFC (#189984)
`SymbolVector` is defined in flang/Semantics/symbol.h, so there is no
need to use a namespace-qualified name for it in lib/Semantics.
[SLP][NFC] Fix uninitialized ReductionRoot in getTreeCost
ReductionRoot was initialized to nullptr instead of the RdxRoot
parameter. This caused two ScaleCost calls (for MinBWs cast cost and
ReductionBitWidth resize cost) to pass nullptr as the user instruction,
and suppressed the "Reduction Cost" line in debug output. In practice
the scale factor is the same because the tree root's main op and the
reduction root share the same basic block, so this is NFC.

[win][x64] Unwind v2: When making headroom leave space for the header (#188368)
When the `ensureHeadroom` call was added during unwind v2 info emission,
it didn't take into account that there is a header of 2-bytes before all
the fixups, so not enough space was actually reserved.
[Offload] Run liboffload unit tests as a part of check-offload (#189731)
Summary:
These are currently only run with check-offload-unit. Make them a part
of the other tests by putting a dependency on it. We did something like
this previously but it was reverted because the tests failed if there
were no GPUs (like in systems that only checked the CPU case) but I
think that has been fixed.
[flang][acc] Add AA implementation for acc operations (#189772)
This PR extends flang's alias analysis so it can reason about values
that originate from OpenACC data and privatization operations, including
values passed through block arguments.
[HLSL] Add GetDimensions to Texture2D.
This commit add the GetDimensions mehtods to Texture2D. For DXIL, it
requires intrinsics that are not yet available. They are added, but not
implemented.
