[clang][APINotes] Do not drop attributes applied after a definition (#222902)
API notes are matched against whichever declaration the compiler
reaches, which can be a redeclaration that follows the definition. When
the definition lives in one module and the annotated redeclaration in
another, that is exactly what happens: checkNewAttributesAfterDef()
warns "attribute declaration must precede definition" and erases the
attribute, so the annotation is silently lost.
The warning exists to tell users that an attribute they wrote has no
effect. Attributes from API notes are not written in the source, so the
warning has nowhere to point and there is nothing for the user to
correct. Skip attributes with an invalid location, alongside the
existing exceptions.

[X86] Fix i64-to-bf16 conversion crash on 32-bit targets (#222934)
Converting a loaded `i64` to `bfloat` can crash instruction selection on
i686:
```llvm
define bfloat @convert(ptr %p) {
%value = load i64, ptr %p
%result = sitofp i64 %value to bfloat
ret bfloat %result
}
```
With `llc -mtriple=i686-linux-gnu`, this hits:
```text
Do not know how to custom type legalize this operation!
```
The X86 DAG combine folds the load and conversion into an x87 `FILD`
node
before type legalization. It already excludes `f16` and `f128`, but was
missing
`bf16`, leaving the legalizer with an unsupported result type.
Add `bf16` to that exclusion. This lets the existing legalization
promote the
conversion through `f32` and then round to bf16. The change also covers
the
constrained signed conversion, which uses the same combine.

[lldb][Windows] Make RM_RF actually delete files (#222950)
On Windows `RM_RF` was `rd /s /q`, which only removes directories — so
any `$(call RM_RF,...)` naming files silently did nothing, and `|| (exit
0)` hid it. POSIX gets `rm -rf`, which removes both.
`clean::` recipes pass file globs and usually run before the build
(`all: clean ...`), so stale artifacts survived into the next run. Hits
upstream `functionalities/disassembler-variables` too.
Fix adds `del /f /q`, joined with `&` not `&&` so `rd` still runs when
the glob matched no files.
This is a follow up to 7d42028e806ab2b17af22ddb8417432e4781d4aa

same AA tags.

[SPIRV] Emit NonSemantic DebugDeclare, DebugExpression and DebugOperation (#222011)
Add support for
[DebugDeclare](https://github.khronos.org/SPIRV-Registry/nonsemantic/NonSemantic.Shader.DebugInfo.html#DebugDeclare),
[DebugExpression](https://github.khronos.org/SPIRV-Registry/nonsemantic/NonSemantic.Shader.DebugInfo.html#DebugExpression)
and
[DebugOperation](https://github.khronos.org/SPIRV-Registry/nonsemantic/NonSemantic.Shader.DebugInfo.html#DebugOperation).
Changes:
- Emit DebugDeclare from an indirect DBG_VALUE whose location register
is defined by OpVariable, which is what the spec requires of the
Variable operand. LLVM IR `#dbg_declare` does not survive as its own
opcode in MIR, `IRTranslator` [lowers
it](https://github.com/llvm/llvm-project/blob/06d0711313b763b65c7e4a9e8613893d7760b6f6/llvm/lib/CodeGen/GlobalISel/IRTranslator.cpp#L4592-L4596)
to an indirect DBG_VALUE.
- DebugDeclare has a `Indexes` operand that didn't find necessary to
implement. The SPIRV-LLVM Translator has no support for it either in
both modes (ir <-> spv).
- The following cases are unhandled to avoid emitting invalid code (see
below comment about spirv-val):
- an access chain into a field
([debug-declare-access-chain.ll](https://github.com/llvm/llvm-project/blob/users/mgcarrasco/nsdi-debug-declare-new/llvm/test/CodeGen/SPIRV/debug-info/debug-declare-access-chain.ll))
- an OpFunctionParameter for a byval argument
([debug-declare-function-parameter.ll](https://github.com/llvm/llvm-project/blob/users/mgcarrasco/nsdi-debug-declare-new/llvm/test/CodeGen/SPIRV/debug-info/debug-declare-function-parameter.ll))
- a constant address
([debug-declare-int-storage.ll](https://github.com/llvm/llvm-project/blob/users/mgcarrasco/nsdi-debug-declare-new/llvm/test/CodeGen/SPIRV/debug-info/debug-declare-int-storage.ll))
- a register left without a def after dead storage was erased
([debug-declare-dead-alloca.ll](https://github.com/llvm/llvm-project/blob/users/mgcarrasco/nsdi-debug-declare-new/llvm/test/CodeGen/SPIRV/debug-info/debug-declare-dead-alloca.ll))
- a variadic #dbg_value
([debug-declare-dbg-value-variadic.ll](https://github.com/llvm/llvm-project/blob/users/mgcarrasco/nsdi-debug-declare-new/llvm/test/CodeGen/SPIRV/debug-info/debug-declare-dbg-value-variadic.ll))
- an expression using an unmapped operation
([debug-declare-expression-unsupported.ll](https://github.com/llvm/llvm-project/blob/users/mgcarrasco/nsdi-debug-declare-new/llvm/test/CodeGen/SPIRV/debug-info/debug-declare-expression-unsupported.ll))
- a variable whose DebugLocalVariable was not emitted
([debug-declare-skip-type.ll](https://github.com/llvm/llvm-project/blob/users/mgcarrasco/nsdi-debug-declare-new/llvm/test/CodeGen/SPIRV/debug-info/debug-declare-skip-type.ll))
- Collect expressions from MIR, so DebugExpression and DebugOperation
are emitted at module scope and shared by every declare using the same
DIExpression.
- Map the nine operations the instruction set defines, and reject an
expression whole when an argument does not fit in 32 bits (as per spec).
- Cache DebugLocalVariable result ids, which emitDebugLocalVariable
already returned but nothing stored.
- Add tests for each emitted and skipped case, for the interaction with
DebugLine and DebugScope, and for the expression operations.
spirv-val and the spec disagree in two places, in opposite directions:
- DebugDeclare's Variable operand: spirv-val accepts an
OpFunctionParameter, while the spec names only OpVariable. This patch
follows the spec, so the byval case is skipped even though spirv-val
would take it, see
[debug-declare-function-parameter.ll](https://github.com/llvm/llvm-project/blob/users/mgcarrasco/nsdi-debug-declare-new/llvm/test/CodeGen/SPIRV/debug-info/debug-declare-function-parameter.ll).
- DebugGlobalVariable's Variable operand: spirv-val rejects a
DebugExpression there although the spec permits one,
KhronosGroup/SPIRV-Tools#6469, see
[debug-global-variable-constant-value.ll](https://github.com/llvm/llvm-project/blob/users/mgcarrasco/nsdi-debug-declare-new/llvm/test/CodeGen/SPIRV/debug-info/debug-global-variable-constant-value.ll).

[lldb-dap] Report the compile unit of a stack frame (#222512)
Add StackFrame.compileUnitId, an id that names the frame's compile unit
within the module already reported as StackFrame.moduleId. Clients
resolve it through the compileUnits request, which now reports the same
id on each CompileUnit and takes an optional compileUnitIds filter to
ask for individual compile units instead of the module's full list.
CompileUnitsRequestHandler declared its arguments optional but
dereferenced them unconditionally, so a compileUnits request carrying no
arguments crashed the adapter. Drop the optional and let the request
framework reject the request instead.

This patch implements pthread_attr_getscope and pthread_attr_setscope.
Same as other libraries, we only support the system contention scope
(PTHREAD_SCOPE_SYSTEM). Process contention scope (PTHREAD_SCOPE_PROCESS)
is not supported, and would basically require a userspace N:M threading
implementation. Since this value cannot be checked in the kernel, I
reject it directly during the attribute set operation, and don't even
bother storing it in the attribute object.

[lldb][debugserver][NFC] Share the expedited-memory type and emitters (#222911)
Expedited memory had two representations:
- The frame pointer backchain used `StackMemory`, a fixed
`uint8_t[2 * sizeof(nub_addr_t)]` plus a length, held in a `std::map`
keyed
by frame address.
- Frame 0's window used `ExpeditedMemory`, which owns a
`std::vector<uint8_t>`.
Three call sites then open-coded the same emit loop, twice into a JSON
array
and once into a stop reply.
Keep `ExpeditedMemory` for both and emit through
`AppendExpeditedMemoryToJSON`
and `AppendExpeditedMemoryToStopReply`. `ReadFrameZeroStackMemory`'s
local
`read_range` lambda becomes `AppendExpeditedMemory`. `ReadStackMemory`
keeps
its own read, because it needs the bytes to continue the walk.
`ReadStackMemory` gains an explicit `visited` set. It previously relied
on its
`std::map` to stop a corrupt frame pointer chain that loops back on
itself, by
testing whether the key was already present. A `std::vector` has no such
test,
so the guard becomes explicit. This keeps the existing behavior rather
than
changing it.
Chunk count and chunk sizes are unchanged. Backchain chunks now go out
in
frame-walk order rather than ascending frame address; the bytes for a
given
address are the same either way, so the cache the client builds is
unchanged.
This prepares for expediting the another memory read range, which have
arbitrary address and length. `StackMemory`'s fixed buffer cannot hold a
range
of a few hundred bytes, and appending and emitting one costs three lines
with
these functions in place rather than a fourth copy of the emit loop.

[LLVMABI] Handle Atomic types in the LLVM ABI library (#221367)
The LLVM ABI library's type system had no way to represent atomic types,
so Clang's QualTypeMapper was just mapping them directly to the
underlying value type. This resulted in mis-classification of some
function signatures involving atomic types.
This change adds AtomicType to the ABI type system and QualTypeMapper.
The actual classification didn't require any updates. Simply having the
atomic type as a distinct type was sufficient for it to produce the
expected results.

[SandboxVec][Scheduler] Update full state of scheduler when IR changes (#222180)
Up until now the scheduler state has not been maintained fully upon IR
changes.
This is not really needed for correct operation of the current
vectorizer because scheduling happens before emitting the vectorized IR,
so there is no real need for updating the scheduler with the current
implementation. Nevertheless, the implementation may change so the right
thing to do is to make sure the scheduler's state is always correct.
So this patch implements the missing callbacks for erase, move and set
use and updates the scheduler state accordingly.

[clangd] Add missing SymbolKind cases to YAML serialization (#222070)
The YAML index writer maps index::SymbolKind to strings through a list
of enumCase calls that was not updated when Concept, IncludeDirective,
and the template parameter kinds were added to the enum. Writing a
symbol with one of these kinds matches no case, so nothing is emitted
for the value and the next key lands on the same line, producing Kind:
Lang: C. With assertions enabled, the writer aborts rather than emitting
malformed YAML. This affects clangd-indexer --format=yaml when indexing
C++20 concepts.
Add the missing cases so the list mirrors the enum, drop the duplicate
Function entry, and add a test that round-trips every current SymbolKind
through YAML. The binary index format stores the kind as a raw byte and
is unaffected.

[Clang] Refactor instantiation of declarations within concepts (#221707)
After implementation of CWG2369, declarations are instantiated on demand
when evaluating a concept.
This was hinged on TemplateInstantiator, where we intercepted most calls
that need an instantiated declaration. This is almost identity to
SetupConstraintScope, which tries to re-instantiate any declarations to
the current scope. This patch removes SetupConstraintScope because we
can instantiate anything on demand.
The concept normalization patch brings us more troubles when we have to
deal with sugars: declarations instantiated outside of the scope (e.g. a
typedef declaration) are never added/instantiated during instantiation
of concepts: this patch makes that function also look up outer scopes
for those declarations. Note that we couldn't simply make the scope of
concepts 'transparent', since we don't want clashes of instantiated
function parameters.
Also also this added a call to instantiateMissingDeclsToScopeForConcepts
for C++26 fold expressions, before checking any pack sizes.

since the price was wrong but the decision was usually right anyway.
After #205263 the <=i32 shapes lower through a float divide, so the
vector cost model is now describing a sequence that really exists and it
still prices it as scalarization.
This adds scalar entries plus five feature gated vector tables.
Numbers are the maximum llvm-mca Block RThroughput across the CPUs that
fold the shape with the low power lines excluded (atom and jaguar).
Vector entries take the max within the tier a CPU's feature level
selects, since the lookup takes the first matching table. Scalar takes
it across all of them.
rem is priced the same as div because a variable rem is the same
instruction and the hardware hands back the remainder in rdx or AH. For
vector the fold pays a multiply and subtract to recover it but the
divide dominates the throughput so the number doesnt change.
div-rem-strictfp.ll is new and pins the strictfp gate. Two SLP tests run
on forced negative thresholds and needed those raised so both produce
output identical to before at the new value.

[WebAssembly] Select relaxed_trunc for vector fptosi/fptoui with +relaxed-simd (#214148)
Fixes #211273
When `+relaxed-simd` is enabled, plain vector `fptosi`/`fptoui` from `<4
x float>` to `<4 x i32>` is still lowered to
`i32x4.trunc_sat_f32x4_{s,u}`. The relaxed SIMD instructions already
exist in the backend, but they were only wired to the
WebAssembly-specific `llvm.wasm.relaxed.trunc.*` intrinsics—not to
generic `fptosi`/`fptoui` IR.
This matters for frontends like LDC that emit ordinary `fptosi` for SIMD
casts (e.g. `_mm_cvttps_epi32`-style code). With
`+simd128,+relaxed-simd`, we should prefer
`i32x4.relaxed_trunc_f32x4_{s,u}`, which typically lowers more
efficiently
on native SIMD hardware.
The fix adds two TableGen selection patterns in
`WebAssemblyInstrSIMD.td`, gated on `HasRelaxedSIMD` with
`AddedComplexity = 1`, so they win over the existing
`fp_to_sint`/`fp_to_uint` → `trunc_sat` patterns when relaxed SIMD is
available.
This does not require fast-math: for representable inputs, relaxed
truncation matches LLVM semantics; for NaN/out-of-range inputs,
`fptosi`/`fptoui` already produce poison, so the backend is not required
to preserve `trunc_sat`'s
saturating behavior.
Explicit saturating conversions (`llvm.fptosi.sat` / `fp_to_sint_sat`)
and `+simd128`-only targets are unchanged.

[libc] Write LF line endings from cmake_format.py on every platform (#222742)
I ran the libc CMake formatter on Windows and it gave back a file whose
every line had changed:
```
$ printf 'add_library(foo STATIC\n a.c\n)\n' > CMakeLists.txt
$ python libc/utils/cmake_format.py -i CMakeLists.txt
Formatted CMakeLists.txt
$ python -c "print(open('CMakeLists.txt','rb').read())"
b'add_library(foo STATIC\r\n a.c\r\n)\r\n'
```
`format_cmake_content()` joins its lines with `"\n"`, but
`process_file()` hands that string to `open(temp_file, "w",
encoding="utf-8")`, and a text-mode write substitutes the platform line
separator. So on Windows, reformatting one command in a file rewrites
the endings of the whole file. `.gitattributes` declares no `text`/`eol`
rules and `llvm/docs/GettingStarted.md` tells people to clone with
`core.autocrlf=false`, so nothing normalizes those endings back before
the commit.
The read side already normalizes: `open(..., "r")` gives universal
newlines, so a CRLF file is LF by the time the formatter sees it.
Passing `newline="\n"` on the write makes both ends agree and gives the
same bytes on every platform.
The same substitution applies to stdout, which affects the piped output
and the `--diff` text (a CRLF diff does not apply against an LF file),
so I configured stdout the same way in `main()`.
One behaviour change worth flagging: on Windows, a CMake file that
currently has CRLF endings and needs reformatting now comes out with LF
rather than CRLF. Files that are already formatted are not written at
all, before or after, since the comparison is made on the LF-normalized
read.
For the tests, everything in `cmake_format_test.py` today asserts on the
string returned by `format_cmake_content()`, so nothing covers what
lands on disk. I added two cases that compare the bytes on disk and on
stdout against that string. They fail on Windows before this change (the
assertion prints `b'...\r\n...' != b'...\n...'`) and pass after; on
Linux and macOS they pass either way, since the separator is already LF.
The file went from 47 to 49 tests, all passing under `python -m unittest
cmake_format_test`.
I did not have `black` available on that machine, so the added code
follows the surrounding style by hand rather than by running the
formatter.

[clang][CodeGen] Emit lifetime markers for block-scoped compound literals in C (#219045)
In C (C99/C11/C23 §6.2.4.5), block-scoped compound literals have
automatic storage duration extending to the end of the enclosing block
scope. Previously, Clang emitted alloca storage without lifetime
markers (@llvm.lifetime.start / @llvm.lifetime.end), preventing LLVM's
StackColoring pass from merging stack slots across disjoint scopes and
inflating stack frame size.
Following John McCall's guidance in #68746:
1. In Sema, record block-scoped compound literals in ExprCleanupObjects
so
the enclosing full-expression is wrapped in an ExprWithCleanups.
2. In CodeGen, emit @llvm.lifetime.start before evaluating initializers
and
schedule CallLifetimeEnd as a cleanup.
Checking a build of an x86_64 Linux kernel defconfig build, this shaves
448 bytes off the stack usage for azx_probe(), one of the larger stack
users in the kernel.

[SPIRV] Refactor implicit binding legalization (#222848)
This change rewrites the `SPIRVLegalizeImplicitBinding` pass so that
binding collection is driven by intrinsic declarations rather than a
full-module instruction walk.
Previously, the pass used an `InstVisitor` to visit every instruction in
the module and find calls to a small set of intrinsics. The new
implementation iterates over the intrinsic declarations and their users,
making the cost proportional to the number of relevant resource calls
rather than the size of the module.
There is no change to the SPIR-V emitted for existing shaders. Implicit
bindings are still assigned the same numbers.
Other improvements include:
- Order IDs are extracted once into a `SmallVector` instead of being
recomputed on each sort comparisons.
- The separate `verifyUniqueOrderIdPerResource` walk is folded into the
binding assignment loop.
- Make helpers that replace implicit binding calls static.
- Added a `HasImplicitBinding` flag for early exit and accurate
`Changed` reporting, so a module with no implicit bindings (or with a
declaration that has no users) now returns `PreservedAnalyses::all()`
instead of unconditionally invalidating analyses.

loads/stores even though i16 isn't legal.
Replace TTI.isTypeLegal with DL.fitsInLegalInteger and a check for
a power of 2 number of bytes. This covers i16 and i32 for RISC-V
and i16 for AArch64.
We could further relax this to cover types that the backend can handle
by splitting, but I'd like to leave that for a future patch.
I had to update some existing tests to have more accurate datalayouts.
The RISC-V tests are reduced from existing tests from AArch64 or X86 to
show some of the load sizes that can now be matched.

Pass the Buffer object in buffer creation functions. Add an error
message if the dynamic buffer creation fails.
Add a threaded unit test to verify the BufferPool handles concurrent
buffer creation properly.
Also, fix a few typos in the code.

[RISCV][SLP] Use common alignment when checking constant-stride loads (#222520)
Fix SLP's constant-stride load legality check, which can widen naturally
aligned 32-bit loads into misaligned 64-bit RVV accesses and cause
`SIGBUS`.
In `BoUpSLP::canVectorizeLoads`, the check uses the first sorted load's
alignment, which may be stronger than that of later widened groups. Pass
`CommonAlignment` to `analyzeConstantStrideCandidate` instead, matching
the existing cost model and code generation. This is conservative: it
fixes the legality check without deriving a more precise alignment for
each widened group's starting address, so it may reject some otherwise
legal widening.
### Reproducer
The following reproduces the failure on the tested [SpacemiT K1 / Banana
Pi F3](https://docs.banana-pi.org/en/BPI-F3/BananaPi_BPI-F3) running
RV64 Linux, compiled with `-O3 -march=rv64gcv -mabi=lp64d
-mstrict-align`:
```c
struct Row {
unsigned x, y, padding[5];
};
_Static_assert(sizeof(unsigned) == 4, "requires 32-bit unsigned");
_Static_assert(sizeof(struct Row) == 28, "requires a 28-byte row");
__attribute__((noinline))
void gather_fields(const struct Row *p, unsigned *restrict out) {
p = __builtin_assume_aligned(p, 16);
out[0] = p[0].x + 3;
out[1] = p[0].y + 3;
out[2] = p[1].x + 3;
out[3] = p[1].y + 3;
}
int main(void) {
_Alignas(16) struct Row rows[2] = {
{5, 9, {0}}, {11, 17, {0}}};
unsigned out[4];
gather_fields(rows, out);
return out[0] != 8 || out[1] != 12 ||
out[2] != 14 || out[3] != 20;
}
```
The alignment assumption is satisfied, and the four loads at byte
offsets `0`, `4`, `28`, and `32` are naturally aligned and in bounds.
SLP widens the adjacent pairs into:
```llvm
%v = call <2 x i64> @llvm.experimental.vp.strided.load.v2i64.p0.i64(
ptr align 4 %p, i64 28, <2 x i1> splat (i1 true), i32 2)
```
On RV64 this lowers to:
```asm
li a2, 28
vsetivli zero, 2, e64, m1, ta, ma
vlse64.v v8, (a0), a2
```
whose second active lane accesses `base + 28`, which is not eight-byte
aligned. The legality check incorrectly uses alignment 16, although the
emitted intrinsic already carries `align 4`.
On the tested machine, the example raises `SIGBUS` before the fix and
returns zero afterward. The fixed compiler uses 32-bit vector loads and
retains vectorized arithmetic.

[Clang] [CUDA] Provide device-side definitions of `__cxa_[pure|deleted]_virtual()` (#217427)
Currently, we don't provide definitions of these on the device side, and
since there is also no C++ runtime on the device side, if a call to a
pure or deleted virtual function makes it into the final IR, the program
will fail to assemble because `ptxas` can’t find a definition of
`__cxa_pure_virtual()` or `__cxa_deleted_virtual()`.
This patch updates Clang to emit weak definitions of these functions
that trap.
Fixes #49183, fixes #67533.

[CIR] Emit classic's attributes for a non-byval indirect argument (#222445)
CallConvLowering marked an indirect argument that is not byval with
llvm.byref. Classic gives this argument llvm.nofreeobj, llvm.noundef,
llvm.align, and llvm.dereferenceable instead.
A call site forwarding such a parameter used to identify it by reading
llvm.byref back, so the pass now records the parameter where the
signature rewrite creates it. The "byref" vocabulary is removed, since
it no longer names anything CIR emits.

Introduction of Composite Profile section in ExtBinary format (#166553)
New sections are introduced for storing profile of vairous types:
* SecCompositeProfile (like SecLBRProfile but can conain multi-type
profile)
* SecCompositeFuncOffsetTable (like SecFuncOffsetTable but offsets point
to SecCompositeProfile)
The only change in the structure of ExtBinary is a substitution of
SecLBRProfile and SecFuncOffsetTable sections by new (composite) ones,
so, to void duplication of layout description and handling, all changes
are done on low-level: section types are modified in the existing layout
right before profile writing.
No new profile types are introduced - this change is rather a
preparation for future profiling extentions: only LBR profile can be
inside currently.
Processing of VTable profile is unmodified.
Extended description is here:
https://discourse.llvm.org/t/rfc-typifiedprofilesection-generalized-per-function-profile-blocks-in-extbinary-format/87881
Testing of the new scenario is added to
llvm/test/tools/llvm-profdata/sample-flatten-profile.test and also new
tests are introduced.

Sequential group database entrypoints require dynamically resizable

Rather than managing raw heap reallocations manually within subsystem
parsers, dynamic growth is encapsulated in a dedicated cpp::vector
container.
Add cpp::vector in libc/src/__support/CPP/vector.h with move semantics,
safe fallible allocation (returning bool for out-of-memory handling
without C++ exceptions), and RAII clean-up for trivially and
non-trivially destructible types.

[OpenMPOpt] Ask the runtime how many of a block's threads can be workers (#221450)
The custom state machine gates a thread on `InitCB < BlockHwSize -
WarpSize`,
reconstructing the worker count from the block size on the assumption
that the
main thread occupies a whole warp above them. That arithmetic has to be
kept in
step with whatever launch geometry the toolchain uses, and when it is
not, the
workers in between are left in neither group, waiting for no parallel
region
while the runtime hands them iterations.
Export the number the device runtime already computes in
`mapping::getMaxTeamThreads()`, which its own generic state machine
gates on, as
`__kmpc_get_max_team_threads()`, and gate on that instead. The new entry
point is
added to the virtual-use callback that keeps the state machine's callees
alive,
and the existing `runtimeFnsAvailable()` check skips the rewrite against
an older
device runtime.
NFC upstream, where `getMaxTeamThreads()` is `BlockSize - WarpSize`. It
matters
for a toolchain whose block is not laid out that way, and it is what
lets the
arithmetic live in one place.
Depends on #221449; the first commit is from that PR.
Tested on gfx90a: `llvm/test/Transforms/{OpenMP,Attributor}` 260 passed,
1
unsupported. No kernel in the AOMP smoke and smoke-fort suites changes
execution
mode.

#222736 removed CIR_AnyPtrType from VectorElementType, so `!cir.vector<2

x86_64-aggregate-nyi.cir parsing at all, so the whole test fails rather
than just that case.
The case only pinned that the x86_64 bridge refuses the shape. No C or
C++ source produces it, since clang rejects a pointer element with
"invalid vector element type", so the verifier is the earlier and better
place for that rejection. The comment in isSupportedType justifying the
bridge-side exclusion is also removed.

The test has lived downstream since the fix that made the function take
its DWARFDie by value instead of by pointer, where the pointee went out
of scope during the walk. Give it a debug map of its own describing
member-hash/2.o rather than extending the shared dummy-debug-map.map,

[CIR][NFCI] Refactor uses of 'mlir::Location' vs 'SourceRange' on calls/etc (#222981)
As a prerequisite to an upcoming patch, emitCall needs access to the
Clang source locations, not just the mlir::Location. We're going to need
this in quite a few more places in the future, since there are various
diagnostics that use clang locations in the code generation.
This patch also has to change the RAII source location stuff, which I
switched to SourceRange. This should improve the amount of data we give
for our source information.
I DID have to remove the assertion on it though, because we do have a
few places that intentionally wanted an invalid location if other stuff
wasn't available (see the CUDA use in particular), but otherwise this
should allow us to improve our source location info, AND use it for
diagnostics in the future.

[Clang] Implement -fkeep-inline-functions (#218533)
Implement the -fkeep-inline-functions flag, which forces selected inline
function definitions to be emitted into the object file even if they
have been inlined into all their callers. The function retention
behavior follows GCC's semantics.
The front-end has been modified to:
- emit the selected functions even if they are unused; and
- add the selected functions to llvm.compiler.used/llvm.used to ensure
they are retained.
The functions selected for emission are inline function definitions that
are available in the current translation unit. available_externally
definitions are excluded because their authoritative definitions are
expected to be emitted by another translation unit.
This is also done for C99 inline function external definitions with
external linkage, which would normally be emitted into the object file
anyway, to ensure the functions are retained for LTO purposes.
See the proposed Clang documentation update for details on the function
selection criteria.

[BOLT][AArch64][Android] Only the dumping thread can longjmp (#222719)
`__bolt_instr_recovery_active` is a process global flag and the reader
in `boltHandleFatalAndRecover()` runs on any thread. When a dump is in
flight, another thread that fails `assert()` or exhausts `GlobalAlloc`
in `instrumentIndirectCall()` could see the flag set, longjmp with the
dumping thread's buffer and restore the dump thread's sp/fp/lr. This
is wrong since the thread would then run on the dumping thread's stack
and later release a mutex that it does not own or hold.
`GlobalWriteProfileMutex` already serializes the writers, so one buffer
would be sufficient; only the reader side needs to know who owns the
buffer. Replace the flag with `__bolt_instr_recovery_tid` holding the
owner's thread ID, and longjmp only when it matches `__gettid()`. Other
threads will fall through to just record the failure and return.
Added a `__gettid()` syscall wrapper, for aarch64 only.

the resulting FPDiff's magnitude has been rounded up to a multiple of the
platform's minimum stack alignment.
In this re-land there is a fixup to 234ce03692ede13ffd2fcb35570d801c1e332814,
which, because of the wrong order, wasn't actually moving NumBytes after
FPDiff had been re-aligned.

[SampleProfile] Ignore unsampled callees in profile anchors (#219335)
Sample profiles can retain zero-count callee entries in both flattened
body call targets and
unflattened callsite samples:
```text
probe 12:
foo: 10
cleanup: 0
```
Counting every entry as a distinct callee converts the uniquely sampled
foo callsite into
UnknownIndirectCallee. It then fails to match the direct IR call to foo,
causing valid
samples to be reported as stale.
Ignore zero-count entries when the same location has a sampled callee.
Preserve the existing
behavior for genuine multi-callee sites and locations where every callee
has zero samples.
```text
foo: 10, cleanup: 0 -> foo
foo: 10, bar: 1 -> UnknownIndirectCallee
foo: 0, cleanup: 0 -> unchanged
```
The change covers both:
- flattened call targets from body samples;
- inline callees from unflattened callsite samples.
## Related fixes
This is downstream profile-matching robustness related to #219079.
Those changes prevent invalid pseudo-probe context earlier in the
pipeline. This change
ensures that any zero-sample entries reaching the profile matcher are
not treated as
evidence of another executed callee.
## Tests
Added regression coverage for zero-sample callees, genuine multiple
sampled callees,
flattened body targets, and unflattened callsite samples.

[flang] Do not hoist fir.field_index out of loops (#222891)
Lowering a consumer of a !fir.field value inspects its defining
operation: for a record whose layout is known at compile time the field
becomes an LLVM GEP struct index, which must be a constant, and
otherwise the `field` attribute is read off the defining op. A field
value therefore may not be a block argument.
LICM broke that. fir.field_index is Pure and takes no operands, so it is
trivially loop-invariant and was hoisted out of the loop. Lowering emits
one inside each arm of a construct -- for example the CASEs of a SELECT
CASE that each pass a different component of the same derived type as an
actual argument -- so hoisting them left those arms as
otherwise-identical blocks differing only in that operand. Block merging
then merged them and threaded the field through a new block argument,
and codegen aborted with "must be a constant".
Leave producers of a !fir.field where they are. The arms then differ by
an operation rather than by an operand, so they are no longer merge
candidates. Consumers are unaffected and still hoist: fir.coordinate_of
uses the attribute form of the field, so it does not depend on the
fir.field_index value.
The check keys on the result type rather than on FieldIndexOp so that
any operation producing a !fir.field is covered, and sits in the
predicate shared by the direct-loop and nested-region hoisting paths.

[orc-rt] Refactor RTTI for cross-library support, add C API (#222946)
Identify types by name rather than by the address of a per-type ID
object, so that a type's identity survives crossing a library boundary:
an object may be constructed by one library and have its type queried by
another, each with its own copy of orc-rt, where per-type addresses
would not agree. Participating classes now declare an RTTIName, which
must be unique across the process.
RTTIRoot records which library produced each value, so same-library
queries still resolve by pointer comparison, and only cross-library ones
fall back to strcmp.
Adds orc-rt-c/support/RTTI.h to expose this to C.
ORC_RT_RTTI_PARTICIPANT and ORC_RT_C_RTTI_IMPL declare and define a
per-type cast entry point, reached via ORC_RT_DYNCAST, alongside
orc_rt_RTTIRoot_getTypeName for logging. This replaces the
orc_rt_Error_TypeId API (orc_rt_Error_getTypeId,
orc_rt_StringError_getTypeId), which exposed ID addresses and so could
not work across libraries. orc_rt_ErrorRef moves from CoreTypes.h to
Error.h.
RTTICrossDylibTest checks identity across a real boundary: its helper
library links its own copy of orc-rt-bedrock, giving it a distinct
library ID.

[flang][OpenACC] Allocate bufferized recipe descriptors in device memory (#223028)
ACCRecipeBufferization places the descriptor of a bufferized recipe
clause next to the variable it holds. When the clause sits inside a
compute construct and the variable is already produced by a data entry
operation, that memory is host memory no data clause maps, so device
code reading the descriptor through it gets a host address.
Place the descriptor in the construct region in that case. The region is
device memory and needs no data clause of its own, and the mapped
variable is a legal live-in since a data entry operation produces it.
The region entry block is used rather than the clause operation so that
a clause on a nested loop does not allocate on every iteration.

[CodeGen][SafeStack] Successful InlineFunction should force a recalculation of potentially stale DominatorTree (#222820)
In commit 51a25846c198, Safe Stack began preserving the `DominatorTree`
by the end of the pass' run. Updates to the `DominatorTree` were then
made lazily via inclusion of `DomTreeUpdater` and its use with
`SplitBlockAndInsertIfThen`. Preservation was maintained when updated to
the new pass manager in 3bd517205799. However, there was an overlooked
case where the `DominatorTree` would remain stale by the end of the Safe
Stack pass if the actions under `TryInlinePointerAddress` completed
successfully and modified the caller's CFG.
The conditions for a stale `DominatorTree` to exist are roughly:
1. Safe Stack obtains the Unsafe Stack pointer location as a `CallInst`
(i.e. one way is `-safestack-use-pointer-address`)
2. `__safestack_pointer_address` is defined and inlined successfully.
3. The inlining changes the CFG such that a recalculated `DominatorTree`
would differ.
4. `DominatorTree` remains unchanged since it is preserved and currently
not recalculated.
Here's a simple example that demonstrates the issue:
```
@unsafe_stack_pointer_a = thread_local global ptr null
@unsafe_stack_pointer_b = thread_local global ptr null
declare i32 @get_runtime_mode() nounwind willreturn memory(none)
declare void @escape(ptr)
define ptr @__safestack_pointer_address() alwaysinline {
entry:
%first = call i32 @get_runtime_mode()
%use_a = icmp eq i32 %first, 0
br i1 %use_a, label %a, label %b
a:
ret ptr @unsafe_stack_pointer_a
b:
ret ptr @unsafe_stack_pointer_b
}
define i32 @caller() safestack {
entry:
%unsafe = alloca i32, align 4
call void @escape(ptr %unsafe)
%second = call i32 @get_runtime_mode()
ret i32 %second
}
```
```
> opt -mtriple=x86_64-pc-linux-gnu -safestack-use-pointer-address -passes=require<libcall-lowering-info>,function(safe-stack,verify<domtree>) -disable-output example.ll
DominatorTree is different than a freshly computed one!
Current:
=============================--------------------------------
Inorder Dominator Tree: DFSNumbers invalid: 0 slow queries.
[1] %entry {4294967295,4294967295} [0]
Roots: %entry
Freshly computed tree:
=============================--------------------------------
Inorder Dominator Tree: DFSNumbers invalid: 0 slow queries.
[1] %entry {4294967295,4294967295} [0]
[2] %a.i {4294967295,4294967295} [1]
[2] %__safestack_pointer_address.exit {4294967295,4294967295} [1]
[2] %b.i {4294967295,4294967295} [1]
Roots: %entry
```
To avoid a stale `DominatorTree` by the end of the Safe Stack pass, I
propose calling `recalculate` on the `DominatorTree` for the function
which will have the call to `__safestack_pointer_address` inlined
assuming the inlining was successful and `DomTreeUpdater` is non-NULL.

seemed nice, we should just do it.
This was done primarily by removing static from templates in headers and
then deleting any unused templates in translation units.
Previously attempted to land this in #221480, but accidentally merged
into a user branch rather than main.

[IVDescriptors] Implement MonotonicDescriptor (#214490)
RFC link:
https://discourse.llvm.org/t/rfc-loop-vectorization-of-compress-store-expand-load-patterns/86442
"Monotonic" variable is similar to induction variable, but its value is
updated under some condition, e.g.:
```
int idx = 0;
for(int i = 0; i < n; ++i) {
// some uses of idx
if (cond)
++idx;
}
```
In this example, `i` is induction variable and `idx` is monotonic
variable: it's updated only when cond == true. In LLVM IR, this looks
like:
```
loop_header:
%monotonic_phi = phi [ %start, %preheader ], [ %update, %latch ]
br i1 %do_step, label %step_bb, label %latch
step_bb:
%step = add/gep %monotonic_phi, %step_val
br label %latch
latch:
%update = phi [ %monotonic_phi, %loop_header ], [ %step, %step_bb ]
br label %loop_header
```
This initial patch only matches the case where `%update` directly
selects between the `%monotonic_phi` or the step. We also limit the
descriptor to only matching cases where all users of the
`%monotonic_phi` are loads/stores that can be mapped to expandloads or
compresstores.
This is a continuation Sergey Kachkov's patch (#140720).

[AArch64] Form CCMP for CBB and CBH (#221113)

| CmpBB => / |
| / | Tail |
| / | | |
Tail | | |

where Head is terminated by a conditional branch and CmpBB contains
a cmp + conditional branch.
We usually try to split any fused conditional branches to be able to
form CCMP. However, in the case of CBB and CBH, splitting the fused
conditional branch in CmpBB could require the insertion of explicit
zero- or sign-extensions for both operands. In the Head block we can
cheaply fuse at least one of the extensions into cmp.
We therefore convert CBB and CBH unconditionally when we find them in
the Head block. In the CmpBB block, we only do the transformation if
neither operands needs an extension.

[llvm] Avoid PREL32 overflow to .data.rel.ro on AArch64 and re-enable (#222809)
Under the [AArch64 Small Code
Model](https://github.com/ARM-software/abi-aa/blob/main/sysvabi64/sysvabi64.rst#code-models),
the text segment (containing .text and .rodata) is limited to 2GB, but
the combined span of text and data segments can be up to 4GB.
When a relative lookup table is emitted in .rodata but references target
operands that require dynamic relocations (placed in .data.rel.ro in the
data segment), the distance between .rodata and .data.rel.ro can legally
exceed the 2GB range of signed 32-bit R_AARCH64_PREL32 relocations.
In this PR:
1. Ensure that on AArch64, lookup table operands do not need dynamic
relocations. If the lookup table were in `.rodata` (text segment), then
any of the target components would need to be in the data segment, so
the dynamic reloc check would suffice.
2. Re-enable RelLookupTableConverter for AArch64 (while keeping Darwin
disabled as before).
3. Limit the existing `AArch64/no_relative_lookup_table.ll` test to just
darwin aarch64.
4. Move the `X86/relative_lookup_table.ll` into the parent dir since
those checks are (mostly) generic, and allow those same checks to be run
for aarch64. That also includes a minor refactor for not checking the
`unnamed_addr` bit since `unnamed_addr` is
[dropped](https://github.com/llvm/llvm-project/blob/6959b7d081df5fb2349e67e0d8e8e87841fa10d9/llvm/lib/Transforms/Utils/RelLookupTableConverter.cpp#L82)

[CIR][AMDGPU] Let amdgcn_lerp and ds_swizzle use the generic codegen path (#222204)
__builtin_amdgcn_lerp and __builtin_amdgcn_ds_swizzle both map 1:1 onto
concrete (non-overloaded) intrinsics and carry the ClangBuiltin<> marker
in IntrinsicsAMDGPU.td, so EmitBuiltinExpr already lowers them
automatically by forwarding the arguments to the intrinsic.

[orc-rt] Add SocketHandle, NativeSocketHandle APIs (#223114)
SocketHandle is an owning wrapper for a NativeSocketHandle value, and
closes the native socket on destruction.
NativeSocketHandle is a typedef for the platform's native socket handle
type.
Only POSIX is implemented in this patch (in sys/posix/SocketHandle.cpp).
Windows support will be added later.
This will be used for an upcoming SimpleRemote-based ControllerAccess
implementation that uses sockets for transport (SocketSimpleRemoteCA).

Fortran code that uses integer(8) arguments, including

omp_integer_kind (typically kind 4). Added *_8 specific procedures to
named generic interfaces in omp_lib, exported matching Fortran and C
runtime entry points, and implemented the *_8 functions as thin wrappers
that saturate-convert arguments to 32-bit and call the existing APIs.

[Flang][Driver]Implemented support for option -momit-leaf-frame-pointer/-mno-omit-leaf-frame-pointer in flang (#216700)
Added support for `-momit-leaf-frame-pointer` /
`-mno-omit-leaf-frame-pointer` in the Flang compiler.
- The driver resolves the flags via `getFramePointerKind()` and forwards
`-mframe-pointer=<kind>` to flang -fc1, resulting in the LLVM IR
function attribute "frame-pointer"
- These options, used with `-fno-omit-frame-pointer`, control whether
leaf functions (functions that don't call other functions) retain or
omit the frame pointer.
- `fno-omit-frame-pointer -momit-leaf-frame-pointe`r : Keep the frame
pointer in non-leaf functions, but omit it in leaf functions (produces
"frame-pointer"="non-leaf").
- `fno-omit-frame-pointer -mno-omit-leaf-frame-pointe`r : Keep the frame
pointer in all functions, including leaf functions (produces
"frame-pointer"="all").

IR: Introduce "thread-model" module flag (#222768)
Introduce the replacement for TargetOptions::ThreadModel, but
does not yet wire up the uses. This maintains the current values,
but I question if it makes sense to retain "posix" as the default.
POSIX sounds very target opinionated, but isn't used in a non-binary
way anywhere. Alternatively we could have a simple singlethread binary
flag, or name this something more general.
Follows the precedent of float-abi. It happens the triple default
is just POSIX, but theoretically targets like AVR should be defaulting
to singlethread.

[RISCV] Add PseudoTAILX7, PseudoTAILReg for cf-protection-branch (#220657)
Previously, PseudoTAIL selected between X6 and X7 at encode time by
checking the Zicfilp feature bit via getTailExpandUseRegNo. This is
incorrect for the codegen path because -fcf-protection=branch can emit
lpad without requiring Zicfilp to be enabled.
Add PseudoTAILX7 for codegen: when cf-protection-branch is active,
ISelLowering and the machine outliner now emit PseudoTAILX7 which
always expands using X7. The existing PseudoTAIL behavior is unchanged
— it still selects X6 or X7 based on Zicfilp at encode time, as
documented in the assembler manual.
Also add PseudoTAILReg ("tail address, register") assembly form that
lets users explicitly specify the scratch register for AUIPC+JALR
expansion, per the proposed syntax in

[orc-rt] Reduce SimpleRemoteCA to transport-independent utils (#223141)
Reduce SimpleRemoteCA to the transport-independent parts: opcodes, setup
and hang-up payload encoding, message validation and dispatch, and the
table of calls awaiting a result. Subclasses are now responsible for the
connection state and synchronization, since they'll usually want to
implement these things for their transports anyway (or the transport
will already manage connection-state/synchronization).
takePendingCall becomes pure virtual, since subclasses must synchronize
access to the pending-call table.
The header moves from orc-rt-internal/ to orc-rt/: with the transport a
subclass concern, there's no reason to preclude library clients from
writing one.

expensive createAddRecFromPHI machinery in many cases.
This is not completely NFC: previously we created SCEVUnknown for a
trivial AddRec with step 0, now we return the start value.
This gives a modest geomean compile-time decrease

With larger decreases for more SCEV-heavy workloads.

[clang][ARM] Use sponentry for setjmp on Windows ARM32 (#222366)
On Windows, _setjmp and _setjmpex take a second argument, the frame,
which the CRT stores in the jmp_buf and which longjmp later hands to
RtlUnwindEx as the frame to unwind. On aarch64, this is the stack pointer
on entry to the function, while x86_64 takes the function frame address.
ARM expects the same as aarch64 here, the stack pointer on entry.

[KnownFPClass] Restrict KnownFPClass::bitcast/toKnownBits deductions to verified FP semantics (#221133)
`KnownFPClass::bitcast` and `KnownFPClass::toKnownBits` previously made
deductions for floating-point semantics whose bit representations had
not been verified.
I have made it so `KnownFPClass::bitcast` and
`KnownFPClass::toKnownBits` return `fcAllFlags`/unknown for any
`APFloat` semantics we have not verified. Currently, this prevents
potentially invalid deductions for `PPCDoubleDouble` (mostly in regards
to the signbit and endianess). It also allows these functions to be
"safely" used with the 4/6/8 bit floating point types since we
conservatively return unknown.
Currently the list of supported/verified semantics for both `bitcast`
and `toKnownBits` are:
```
IEEEhalf
BFloat
IEEEsingle
IEEEdouble
IEEEquad
x87DoubleExtended
```

check that explicit constructor calls work at compile time.
However, the test case left var.a uninitialized and the copy constructor
reads an unitialized value. MSVC diagnoses this, but clang currently
fails to do so.
Change the test case to remove the unrelated problem of an uninitialized
read.

[CMake] Disable linker version scripts for Emscripten (#221647)
Emscripten reports itself as a Unix-like CMake platform, causing LLVM to
set `LLVM_HAVE_LINK_VERSION_SCRIPT` and pass GNU/ELF `--version-script`
options when linking shared libraries.
Emscripten uses `wasm-ld`, which does not support GNU version scripts
and currently reports:
```
em++: warning: ignoring unsupported linker flag: `--version-script`
```
Treat Emscripten like the other platforms without version-script
support. This prevents LLVM and Clang shared-library targets from
passing an unsupported linker option.
This was encountered while building LLVM 23.1.0 for both wasm32 and
wasm64 with Emscripten 6.x in emscripten-forge.

[lldb] Bound Mach-O symtab allocation to the file size (#222955)
Opening a Mach-O file whose LC_SYMTAB claims far more symbols than the
file could possibly hold makes lldb ask for hundreds of gigabytes. A
128-byte file with LC_SYMTAB.nsyms = 0x80000000 (the new unit test's
input, built with yaml2obj) reproduces it through `lldb-target-fuzzer`,
the harness that found this bug:
```
==45515== ERROR: libFuzzer: out-of-memory (malloc(171798691840))
#8 std::__1::__split_buffer<lldb_private::Symbol,...>::__split_buffer(...)
#9 std::__1::vector<lldb_private::Symbol,...>::resize(unsigned long)
#10 lldb_private::Symtab::Resize(unsigned long)
#11 ObjectFileMachO::ParseSymtab(lldb_private::Symtab&)
```
`ParseSymtab()` sizes the destination `Symtab`'s `vector<Symbol>`
directly
from `nsyms` and `nindirectsyms`, two counts read from the file's
`LC_SYMTAB` and `LC_DYSYMTAB` commands. `nlist_data`, the view already
built earlier in the function from the bytes the file actually has at
`symoff`, is far smaller than what those counts claim; the guard gating
this code only checks that it is non-empty, not how many nlist records
it can back.
Bound both counts by what `nlist_data` and `indirect_symbol_index_data`
(already clipped to the available bytes) can hold, instead of trusting
the file's counts outright.
Add a unit test whose LC_SYMTAB claims about two billion symbols in a
128-byte file; completing quickly instead of reserving that much space
is the regression check.

[DAGCombiner] Only fold shift+mask compare to rotate if the shift amount divides the bit width (#220743)
DAGCombiner::visitSETCC can turn `(X << S) == (X & -(1 << S))` (or the
srl variant) into `rotl(X, S) == X`, and the other way around, when the
target prefers one form over the other. The two forms are only equivalent when
S divides the bit width. The check used `isPowerOf2(S)`, which is the same
thing for i8/i16/i32/i64 but not for odd widths like i3, where S = 2 is a
power of two that does not divide 3. On x86, which prefers the rotate,
the reporter's i3 function returned the wrong value for two of its eight
inputs.
This changes the `MayTransformRotate` flag passed to
`preferedOpcodeForCmpEqPiecesOfOperand` to check `NumBits % S == 0`
(with S != 0) and fixes the two comments that described the old rule. For legal
scalar types nothing changes. On illegal non power of two widths this
also lets a non power of two amount that divides the width use the rotate
(like i6 with S = 3); that is correct for the same reason and legalizes
through the usual rotate promotion, same as i6 with S = 2 did before. The x86
hook already honors the flag in both directions, so the fix lives in the
target independent code.
Tests: the i3 shl and lshr cases from the issue (must stay shift+mask), an
i6 / S = 3 case (3 divides 6, so the rotate is still allowed), and the
reporter's function.

[clang-nvlink-wrapper] Fix response file handling for the nvlink wrapper (#220249)
Summary:
Response files were not handled correctly because the copied support
used the `nvlink` argument which is not supported by the argument
parser. Pass to the nvlink wrapper using the canonical format and then
reconstruct it when we execute the sub jobs

[Support] Fix the return type of AddOverflow, SubOverflow, and MulOverflow (#223217)
This patch fixes the return type of the 3-argument overloads of
AddOverflow, SubOverflow, and MulOverflow to bool.
Without this patch, these functions are declared with a return type
of T:
template <typename T>
std::enable_if_t<std::is_signed_v<T>, T> AddOverflow(T X, T Y, T
&Result);
even though they return a boolean indicating whether an overflow
occurred, as stated in the comment:
/// Add two signed integers, computing the two's complement truncated
result,
/// returning true if overflow occurred.

[SelectionDAG] Remove unused float promotion in DAGTypeLegalizer (NFC) (#223219)
This patch removes PromotedFloats along with GetPromotedFloat and
SetPromotedFloat. The Mapped bitmask in PerformExpensiveChecks is
adjusted accordingly, shifting the bit for SoftPromotedHalfs.
The last uses of DAGTypeLegalizer::GetPromotedFloat and
DAGTypeLegalizer::SetPromotedFloat were removed on January 26, 2026 in
commit a7d48bd305ef3aa4bd543da6f4cd8682a3d35c32 when TypePromoteFloat
and its associated DAG machinery were removed.
With these accessors gone, DAGTypeLegalizer::PromotedFloats is no longer
populated.

[OpenMP] Change association of some directives from "none" to "explicit" (#222703)
Certain declarative directives are associated with base language
declarations by having the declared entities explicitly listed as
arguments.
Previously these had "none" in OMP.td. Change them to "explicit" to be
consistent with the spec. The existing code does not require any
changes, since the only potentially affected code would be that which
checked the assocation for "none", and the only such cases were applied
to executable directives.

[NFC][ModuleUtils] Move externalize() from module splitting utilities (#221181)
`SplitModule.cpp` and `AMDGPUSplitModule.cpp` each carry an identical
static `externalize()` helper that promotes local-linkage globals to
external + hidden visibility and assigns a stable name to unnamed
entities, so they are named consistently across module partitions.
This patch removes the duplication by moving the helper into
`ModuleUtils` as `llvm::externalize`, and updates both users to call the
shared implementation. No functional changes are intended.
This also prepares for upcoming module splitting utilities to reuse a
single, canonical implementation.
Development of this patch was assisted by AI and reviewed by me.

-----------
[SLP]Reduce logical and/or reductions in the wide leaf type
Logical and/or reductions on i1 with booleanized wide leaves (truncs
of same-op chains, zero-tests of values from [0, 1]) are performed in
the wide type, exposing the underlying consecutive values to the tree;
bit 0 of the result is the final value. Fixes the fragmented reduction
and the gather-of-scalars regression for compile-time-expanded Boolean
reductions.
Fixes #221167
