-----------
[flang][acc] Remove dangling operands in OpenACCUtilsTiling (#208261)
When TILE has more dimensions than the loop's collapse count,
uncollapseLoops() synthesizes an inner loop via `createInnerLoop()`,
which
strips gang attributes from it but forgot to clear the gang operand
values. This left the loop with a non-empty gang operand list but no
device-type attribute, causing LoopOp::getGangValue() to dereference a
null attribute and crash with an assertion failure when the loop also
had
`GANG(STATIC:N) (or NUM/DIM)`.
Fix: also clear the gang operands when stripping gang attributes, so the
loop ends up fully gang-free.

[LLVM][NFC] Remove some global constructors (#208407)
Largely by converting relevant functions or variables to constexpr,
changing the type, converting to static locals, or by outright removal.
PunnedPointer assignment can never be constexpr, because std::memcpy is
not constexpr and type punning is not permitted in a constant-evaluated
context.

[SPIR-V] Fix truncated LinkageAttributes OpDecorate for numeric-named functions (#207332)
LLVM IR allows functions with numeric names (e.g. `@0`). There function
return empty strings on `getName()`, so emitting a `LinkageAttributes`
decoration for it is meaningless.
Fix: skip emitting the `LinkageAttributes` decoration for non-entry
functions with an empty name. Also add a `report_fatal_error` for the
case where an entry point function has no name, since that is invalid
input.

[NVVM][MLIR] Fixed valgrind leak in MMAOp (#208063)
MmaOp::getIntrinsicID triggers an uninitialized-read warning under
Valgrind. `intOverflowBehavior` is optional; in the generated selector
its `has_value()` guarded access can be speculatively loaded before the
guard, reading the empty std::optional's uninitialized payload.
The read is benign: the payload is correctly stack-allocated but
uninitialized while empty, and the loaded value is discarded by the
guard, so this is not incorrect / undefined behavior.
This MR keeps the attribute as optional, but the lowering now resolves
it to a concrete value (wrapped when omitted) before calling
getIntrinsicID, so the selector always reads an initialized value.
`wrapped` matches the PTX spec and the existing lowering, where an
omitted attribute already selected the non-satfinite intrinsic;
intrinsic selection and printed IR are unchanged. Documentation updated
to correct the stale default.

[clang][docs] Rewrite 20 selected Clang docs from reST to Markdown (#208310)
Tracking issue: https://github.com/llvm/llvm-project/issues/201242
Migration guide docs:
https://llvm.org/docs/SphinxQuickstartTemplate.html#markdown-migration-guidelines
RFC:
https://discourse.llvm.org/t/rfc-make-myst-markdown-the-llvm-docs-format-rip-rest/90840
This change was produced with rst2myst plus LLM cleanups.
I manually paged through all of the linked HTML documents looking for
visual artifacts, and I fixed everything I found.
To reviewers: Please spot check the generated HTML below, and spot check
the diff to look for artifacts. This change is too large to review
everything line-by-line, but if you check 10 pages of documentation, and
only find one migration bug, I hope you think that this is good enough
to land. We have existing reST bugs that this fixes (mostly italic
blocks that should be code font spans).

Clang 21.1.8 segfaults during SFINAE overload resolution for

This patch avoids the crash by adding an explicit SFINAE constraint to

[CIR] Represent 'empty' fields in structs/unions (#207033)
Since we do field based GEPs, it isn't really possible to do a
get-address-of a field without representing all the fields in a CIR
struct. This patch makes sure we do that, so we can do the proper GEPs.
This patch also as a drive-by fixes the case where we were searching for
the 'path' inside of an empty base, which we don't represent (and
probably should not need to?).
This patch ALSO adds some NYI diagnostics for cases where we try to get
the address of a `no-unique-address` field, which we are not currently
representing. In the future, we are going to have to start representing
no-unique-address fields inside of a struct as well (plus figure out how
to lower it properly in a way that gets the offsets right), but it isn't
clear this is immediately necessary (as you'd have to take an address of
one to notice?).

[VectorCombine] Fix bailing out of the foldSingleElementStore with a freeze-pending index (#207702)
`foldSingleElementStore` calls `canScalarizeAccess` to decide whether a
single-element store can be scalarized. When the insert index is not a
constant, is provably in-bounds and may be poison, `canScalarizeAccess`
returns `SafeWithFreeze` and stashes a `ToFreeze` value that must later
be consumed by `freeze()` or cleared by `discard()`.
The bail-out for memory being modified between the load and store was
folded into same condition as the scalarizability check:
```cpp
auto ScalarizableIdx = canScalarizeAccess(...);
if (ScalarizableIdx.isUnsafe() || isMemModifiedBetween(...))
return false;
```
When the index took the `SafeWithFreeze` path and memory was modified
between the load and the store, `isMemModifiedBetween` returns true and
hit `return false` while ScalarizableIdx still holds a live `ToFreeze`.
Its destructor then raises:
> Assertion !ToFreeze && "freeze() not called with ToFreeze being set"
### Fix
Move the `isMemModifiedBetween` bail-out above the `canScalarizeAccess`
call so the freeze-pending result is never constructed on the path where
we give up.

Prefetch is a hint that migrates a USM allocation between the host and a

[mlir][tosa] Add constant block scaled support (#205506)
This commit adds support for block scaled tensors.
In particular, the block scaled type has been extended with the
`DenseElementTypeInterface` to allow block scaled data values to be
specified in dense element attributes.
The block scaled type has also been extended to allow optional scale
values to be specified by the type. For now, scale values are not
expected to be propagated beyond their use in the attribute input of a
constant operation. In the future, we may want to propagate these values
to allow certain optimizations.
The `tosa.const` operation has also been updated in the validation pass.

[CodeGen] Disable exact dynamic_cast for duplicable vtables (#205929)
Add `TargetInfo::getVTableUniqueness()`, which returns a
`VTableUniquenessKind` that describes whether a target's ABI guarantees
a class's vtable has a single address program-wide. Apple Mach-O targets
return `UniqueIfStrongLinkage`, since a vague-linkage (weak) vtable may
be autohidden and duplicated per image, while a vtable with strong
linkage (e.g., a class with a key function) still has a unique address.
Every other target keeps the default, `AlwaysUnique`.
Rename the `CodeGenOpts` flag backing `-f[no-]assume-unique-vtables`
from `AssumeUniqueVTables` to `DisableExactDynamicCast`, defaulting to
false so the optimization stays on unless `-fno-assume-unique-vtables`
is given. Use it together with `getVTableUniqueness()` in
`ItaniumCXXABI::hasUniqueVTablePointer()` so a weak vtable on a target
that may duplicate vtables no longer qualifies for the exact
`dynamic_cast` optimization; a vtable with a key function, or any vtable
on a target with `AlwaysUnique` semantics, is unaffected.

[CIR][AArch64] Lower NEON vfms builtins (#207022)
Lower additional AArch64 NEON fused multiply-subtract builtins in CIR.
This covers the ACLE wrappers from section 2.1.1.2.5:
- vfms_f32, vfms_f64, vfmsq_f32, vfmsq_f64
- vfms_lane_f32, vfms_lane_f64, vfmsq_lane_f32, vfmsq_lane_f64
- vfms_laneq_f32, vfms_laneq_f64, vfmsq_laneq_f32, vfmsq_laneq_f64
- vfmss_lane_f32, vfmss_laneq_f32
- vfmsd_lane_f64, vfmsd_laneq_f64
The lowering reuses the existing FMA paths by negating the multiply
operand before emitting llvm.fma. Vector lane forms splat the selected
lane, while scalar lane/laneq forms extract the selected element before
the FMA.
Move the existing ACLE coverage into
clang/test/CodeGen/AArch64/neon/fused-multiply.c and add direct LLVM,
CIR-to-LLVM, and CIR checks. The replaced old-style checks are removed
from the legacy test files.

[VectorCombine] Handle widening/narrowing bitcasts in foldShuffleToIdentity (#187870)
Track lane indices through vector bitcasts that change element count in
foldShuffleToIdentity. Widening bitcasts (e.g. <2 x i32> -> <4 x i16>)
compress R consecutive destination lanes into one source lane, while
narrowing bitcasts (e.g. <4 x i16> -> <2 x i32>) expand each destination
lane into R source lanes.
Also fix identity check, splat mask, and destination type construction
to use Item.size() instead of Ty->getNumElements(), since the Item
vector changes size when passing through element-count-changing
bitcasts.

[WebAssembly] Don't use passive segments for bss in coop threads (#208284)
This commit is an update to `wasm-ld`'s behavior with bss data segments
with `--cooperative-threading`. Previously bss segments were forced to
become passive data segments meaning that a `start` function was emitted
with a `memory.fill` that set the required region of memory to 0. This
isn't required for coop threads though because the module is only
instantiated once and the default pattern for memory is 0, so only
special treatment of TLS segments are required.

[flang][MIF] Fix COSHAPE and THIS_IMAGE(coarray) type mismatch for non-i64 kinds (#208429)
Both COSHAPE and THIS_IMAGE(coarray [,team]) return integer arrays whose
element type is determined by the Fortran KIND argument (default: i32).
The lowering code was ignoring resultType in both cases and hardcoding
i64, which caused downstream type mismatches:
- COSHAPE: SimplifyHLFIRIntrinsics assertion in PRODUCT(COSHAPE(y)) when
the product input type (i64) did not match the declared result type
(i32).
- THIS_IMAGE(coarray): MLIR verifier error on arith.cmpi with mismatched
operand types (i64 vs i32) in comparisons like THIS_IMAGE(a) /=
[5,0,-7].
Fix: derive eleTy from resultType in both genCoshape and genThisImage
and propagate it into the mif.* op's result type. In MIFOpConversion,
extract a shared convertI64SeqToEleTy helper that post-converts the i64
scratch buffer written by the PRIF runtime into the
declared-element-type buffer when the two types differ. Both
MIFCoshapeOpConversion and MIFThisImageOpConversion call this helper.

[libc++] Remove benchmark::DoNotOptimize from custom predicates in benchmarks (#208412)
The point of the custom predicates is to defeat any detection of special
predicates within the library. There isn't much point in adding
`benchmark::DoNotOptimize` on top of that. It can actually hurt, since
it may hide performance changes due to how much/which information we
provide to the compiler.
