-----------
[AArch64] Implement the atomic store with hint intrinsic (#198316)
Adds the following ACLE intrinsic as described in [1]:
void __arm_atomic_store_with_hint(type *ptr, type data,
int memory_order, int hint);
An atomic store instruction is emitted in Clang for this builtin with additional
metadata attached with !mem.cache_hint, which ensures the instruction is
recognised as atomic by later passes in LLVM. When an atomic store is found
with this metadata, it is lowered to the ATOMIC_STORE_HINT pseudo which is
later expanded into an STSHH instruction plus an atomic store.
The hint is a suggestion to the compiler and maps directly to a specific hint
instruction variant in the ISA. The compiler may use this hint when selecting
code sequences, but it is not required to emit a specific hint instruction or a
specific instruction sequence.
Supported atomic store hints are currently:
HINT_STSHH_KEEP: Requests retention of the updated location in the
local cache of the updating PE.
HINT_STSHH_STRM: Requests that the updated location not be retained
in the local cache of the updating PE.

This reverts commit 688119653fd40fa46244e1c300e728677a4f001a.
This caused a regression in Fujitsu test 0291/0291_0008.f with
`-ffast-math -march=native -03`. That test does a conversion that always
overflows, so without saturating math it produces poison, which causes
it to treat the rest of the routine as unreachable, resulting in a crash
on x86. I'll have to try another approach.

[ValueTracking] An or recurrence with a non-zero start value is non-zero (#226155)
Or-ing anything into a non-zero value keeps it non-zero, so
`isNonZeroRecurrence` can accept a simple `%iv = or %iv, %step`
recurrence with a non-zero constant start value, regardless of the step.
The first commit precommits the tests in `phi-known-nonzero.ll`.
This is split out of #222334. Together with a follow-up that stops
limiting the recursion depth for single-incoming (LCSSA) phis in
`isKnownNonZero`, it lets LoopIdiomRecognize (#222373) form `llvm.ctlz`
for the clz loop in ffmpeg's `sbc_calc_scalefactors`.

-----------
[Polly] Materialize escaping scalars from empty-domain statements as poison (#220008)
Problem Summary: In a versioned SCoP, Polly may remove a statement with
an empty iteration domain before building its access relations. If that
statement contains an escaping MemoryKind::Value MUST_WRITE access,
removing the
statement also prevents the corresponding ScopArrayInfo from being
registered. During code generation, Polly then fails to materialize the
escaping scalar, leaving a merge PHI that refers to a value defined only
on the original path.
This causes an LLVM verifier failure because the value does not dominate
all uses.
Fix: When removeStmtNotInDomainMap() is about to remove a statement with
a null or empty domain, register the ScopArrayInfo for its qualifying
escaping scalar accesses before allowing the statement to be removed.
The statement is still pruned normally, but code generation can now
materialize the scalar through a .s2a slot and reload it on the
optimized merge edge. Since the defining statement is absent on that
path, the reload is poison. This is sound because
the poison is used only for parameter ranges where the original program
already has undefined behavior
The new .merge PHI provides a dominating definition on the optimized
edge, which resolves the verifier failure while keeping the region
optimized.
Fixes #206551

[libclang/python] Fix visitor callback return data type (#221024)
Declare the visitor callbacks return as c_long, i.e. a full register
word rather than c_int.
This is currently causing an issue on s390x, a 64-bit big-endian target.
The V8 JavaScript engine has recently started using libclang as a
dependency
to parse header files. It is currently crashing on s390x with a SIGFPE
due to this issue.
Both the s390x ELF ABI and libffi require the value to be sign/zero
extended to register
size, and leaving it as `c_int` leaves garbage on the high side.
cindex.py calls into libclang through ctypes, which builds the callback
closures using
libffi. With a `c_int` return, ctypes writes only the low 32 bits and
skips the extension
that both the ABI and libffi's closure contract require, so libffi hands
libclang a register
whose high bits are garbage.
Using c_long makes the value fill the register at its native width on
all platforms.

[NVPTX] Extend SETP commuting to support SELP users (#215897)
Extend NVPTX SETP commuting to support predicates used by SELP
instructions.
When commuting a SETP reverses its predicate, update each SELP user by
swapping its true and false operands. This allows MachineCSE to elimiate
redundant inverse comparisons whose predicates are used by both branches
and selects.
Add regression coverage for register and immediate SELP operands. This
also removes redundant predicates from the arbitrary floating-point
conversion tests.

[LLVM][CodeGen][AArch64] Implement expansion for fixed-length get.active.lane.mask. (#225459)
A step in the direction of removing the shouldExpandGetActiveLaneMask
TTI hook. For this PR I've implemented enough functionality to allow all
legalish fixed-length variants of get.active.lane.mask to bypass the
SelectionDAGBuilder based expansion for AArch64.
The AArch64TargetLowering::shouldExpandGetActiveLaneMask restrictions
are related to maintaining current code quality and not because the
expansion code cannot handle them.
Tests are a copy of active_lane_mask.ll with the scalable vector tests
removed.

[mlir][OpenACC] Preserve explicit device numbers in wait lowering (#222604)
WaitOpLowering currently ignores wait_devnum and always passes zero as
the device number to __tgt_acc_wait.
Forward the converted operand when present, adapting it to the runtime's
i32 parameter. Zero-extend narrow unsigned integers, sign-extend narrow
signed or signless integers, and truncate wider operands. Determine
signedness from the original operand type, since LLVM type conversion
makes integer types signless.
Keep the default device number unchanged when wait_devnum is absent.
Add regression coverage for explicit device numbers, integer width and
signedness conversions, index operands, and waits combining if and
async.

[clang][OpenMP] Only accept char strings in the message clause (#226080)
Fixes #140338
The `message` clause accepted any character-typed string, checked with
`isAnyCharacterType()`, but everything that consumes it assumes a `char`
string: Sema evaluates it into a `std::string` for the compile-time
diagnostic, and codegen passes it straight to the `const char *`
parameter of `__kmpc_error` and `__kmpc_push_num_threads_strict`. When
the issue was filed this hit the assertion in
`StringLiteral::getString()`. Since #146405 the assert is gone, but the
underlying problem stayed: in C++ a wide literal like `message(L"bar")`
prints `b<NUL><NUL>` as the error text, and with `at(execution)` a
`wchar_t` array is emitted as the runtime's `char *` argument. C was
only spared because `wchar_t` is an integer typedef there, so the clause
was already rejected.
The clause now only accepts `char` element types, which is what the spec
requires (OpenMP 5.1 §2.5.4: msg-string is a string of `const char *`
type). Wide, `UTF-16/32` and C++20 `u8` literals get the existing
"expected string in 'clause message' - ignoring" warning and the
directive still fires with its generic message, matching what C already
did and what GCC does. Doing this at the single point where the clause
is built covers the diagnostic, both codegen paths, and template
instantiation without touching the evaluator.

layout meet the rank-2 layouts of `load_nd` and `dpas_mx`:
- fully broadcast source to one row per lane: `vector.extract`
- source broadcast over two lane groups to one row per lane:
`vector.extract` plus two `gpu.shuffle`
- fully broadcast source to one column per lane group:
`vector.deinterleave` plus a select on the lane group

[mlir][xevm] Fold xevm.truncf of an xevm.extf round trip (#225875)
A xevm.extf followed by a xevm.truncf through the same pair of formats
returns the value it started from, so the pair can be dropped. Fold it
on the truncf, the way arith::TruncFOp::fold recognizes truncf(extf(a)),
and gate it on APFloatBase::isLosslesslyConvertibleTo of the two formats
the element type attributes stand for.
That gate excludes bf8: it is IEEE-like, so extending a signaling NaN
quiets it and the original value cannot be recovered, which is the same
reason arith does not fold an f8E5M2 round trip. f8 (E4M3, NaN only) and
e2m1 (finite only) do fold.
Mark both ops Pure so the extf left without users is removed and the
pair folds to nothing.

[LifetimeSafety] Revamp how accesses and uses are handled (#225799)
Previously every DeclRefExpr was a use, so naming a pointer, taking its
address
or copying it counted as reading what it points to. Writes were then
exempted
after the fact through a UseFact -> Expr map and a special case for
writes
through references.
Now a use is an access: an lvalue-to-rvalue conversion, a write through
an
assignment, increment or asm output, or a copy of a class object from a
glvalue.
It is recorded on the accessed lvalue's outer origin, the loans saying
which
storage it may name. The visitors for `*p`, `p->f` and `p[i]` already
flow the
base pointer there, so dereferences need no special handling. Reads of a
value
go through readValue(), which records the access; writes peel the outer
origin
directly. Values handed to opaque code still use every level.
Consequences:
- Copying a pointer, taking an address, `(void)p` and `p++` are not
uses.
- Writing through a dangling pointer (`*p = 1`, `p->f = 1`) is now
diagnosed.
- An access of an origin that names a declaration outright is skipped:
it
only holds a loan to that declaration, which is valid wherever it is
named.
- UseFact::IsWritten and markUseAsWrite are removed; kills on assignment
already come from the destination's OriginFlowFact or KillOriginFact.
Fewer use facts are generated, e.g. on the lifetime-safety lit tests:
safety.cpp 1886 -> 882
invalidations.cpp 616 -> 451
nocfg.cpp 544 -> 415
capture-by.cpp 395 -> 324

[TargetParser] Add a list of Intel GPUs, and use it in offload-arch (#222072)
Currently offload-arch prints Intel GPU identifiers like "Intel(R) Data
Center GPU Max 1100" which are not legal values for clang's
--offload-arch option.
Print an architecture name instead, e.g. "xe-pvc". The driver reports a
GPU IP version, the GMDID, for every device. Add a table that maps a
GMDID to a name, and look the device up in it. A device that is missing
from the table is printed by its numeric version, e.g. "xe_35.11.0". A
device whose driver does not report a GMDID is skipped.
The table goes in llvm/TargetParser, next to the other GPU lists,
because other tools need it too. Some of them are LLVM libraries, which
cannot include a clang header.
Every row of IntelGPUTargetParser.def holds a name that --offload-arch
accepts, the major and minor components of the GMDID that the device
reports, and the IGCA (Intel Graphics Compute Architecture) target and
feature sets that the name maps to. The revision component is left out,
so every revision of a device gets the same name. A few names, such as
xe-dg2, cover a whole product line. No device reports a GMDID for those,
so offload-arch never prints them.
The header declares only the functions that offload-arch needs. More
will follow when something needs them.

[DebugInfo] Ignore undefined constexpr constructors in constructor homing. (#221971)
This is a roll-forward of
https://github.com/llvm/llvm-project/pull/218165, which inadvertantly
caused missing debug info in
https://github.com/llvm/llvm-project/issues/221560 due to an existing
issue with standard-layout unions and layout-compatible aliasing (see
[[class.mem]](https://timsong-cpp.github.io/cppwp/n3337/class.mem#19)).
Constexpr constructors without a visible definition in the TU are not
callable in a constexpr context, which means it is not possible to
construct a type in constexpr without emitting debug info for the
constructor itself. Although undefined constexpr constructors are still
callable, they are normal out of line functions, requiring a definition
to link against.

The scalable outer dim guard in `BroadcastOpLowering` only covered the

unrolls the same `dstType.getDimSize(0)` trip count and has the same
bug: broadcasting e.g. `vector<1x4xf32>` to `vector<[3]x4xf32>` only
fills the static minimum lanes via `vector.insert`, leaving the rest as
`ub.poison`.
Widen the guard to cover both cases, and add a regression test.

[lldb][test] Stop deleting the clang module cache between lit runs (#226174)
A test binary's DWARF names the .pcm files in this cache, and make will
not rebuild an up-to-date `a.out` to regenerate them. Deleting it leaves
every ClangImporter test pointing at a deleted module.
Deleting is also redundant: a changed compiler already forces a rebuild
through `tool_prereq` inside of `Makefile.rules`.
On Windows, in swiftlang, this fixes 26 tests in `check-lldb-swift`
(ClangImporter/DWARFImporter/cxx-interop) and 105 "module file does not

[libc++] Re-apply "Build GoogleBenchmark directly from Lit" (#225856)
Previously, we would build GoogleBenchmark against the just-built
library, not against the library being tested. When testing historical
versions of libc++ or other standard libraries, this breaks. So instead
of building Google Benchmark against the just-built library in CMake, do
it from Lit as part of the test suite's configuration.
I'm not a huge fan of using Lit as a poor man's build system and we
should make the CMake test suite self-contained, however this is a step
in the right direction and it removes a major coupling between the test
suite and the regular libc++ build.
This patch re-applies 1bfe9893f3dc which was reverted in 62ea87e542c3
because it broke the Fuchsia bots. This new version of the patch also
threads through the path to the CMake program being used, the CMake
generator and the CMake "make program" from the top-level CMake to the
test-suite, so that the Google Benchmark build can inherit what the
top-level CMake is using.

OpenMP custom reductions with user-defined initializers segfault when

Add `i32` variants of the generic and `.shared::cta` NVVM intrinsics and
select them to `st.bulk` instructions using 32-bit registers. The new
patterns require PTX ISA 9.0 and `sm_100`.
The existing intrinsics continue to represent the original 64-bit forms.

Fix layering failure for clang-doc and flang (#225964)
This was introduced in commit 4989b3b0bb752c436c922d8e65cd7a952038d5db.
* `src/liblzma/api/config.h` is exposed in hdrs of lzma_src_liblzma_api.
* `strip_include_prefix = "src/liblzma/api"` strips the path, exposing
the header as `config.h` in a virtual include directory
(`_virtual_includes/lzma_src_liblzma_api/config.h`).
Fixed by adding `strip_include` to the relevant `config.h` headers that
were causing failures.

[clang] Migrate away from PointerUnion::dyn_cast (NFC) (#226047)
Note that PointerUnion::dyn_cast has been soft deprecated in
PointerUnion.h:
// FIXME: Replace the uses of is(), get() and dyn_cast() with
// isa<T>, cast<T> and the llvm::dyn_cast<T>
Literal migration would result in dyn_cast_if_present (see the
definition of PointerUnion::dyn_cast), but this patch uses dyn_cast on
DeclListNode::Decls in StoredDeclsList because the operands are always
nonnull:
- StoredDeclsList::getAsDecl and StoredDeclsList::getAsList are called
only after verifying !isNull() (in StoredDeclsList::getASTContext,
StoredDeclsList::addOrReplaceDecl, and ASTImporterTest.cpp).
- DeclListNode::Rest is always nonnull because the singly-linked list of
DeclListNode is terminated by a NamedDecl *, not by nullptr.

[flang][cuda][openacc] Resolve DEVICE dummies against !$acc data mapped objects (#225899)
CUDA Fortran generic resolution rejects a call when an actual argument
with
no CUDA data attribute is associated with an ATTRIBUTES(DEVICE) dummy.
That
makes cuBLAS-style generic interfaces unusable inside a structured
OpenACC
data region, even though the mapped objects do have a device copy there:
```
!$acc data copyin(a, b) copyout(c)
call cublaszgemm(transa, transb, m, n, k, alpha, a, lda, b, ldb, beta, c, ldc)
!$acc end data
error: No specific subroutine of generic 'cublaszgemm' matches the actual
arguments
dummy argument 'a=' has ATTRIBUTES(DEVICE) but its associated actual
argument has no CUDA data attribute
```
Treat an object mapped by an enclosing structured `acc data` construct
as if
the actual had CUDADataAttr::UseDevice, which is the attribute already
used
for `host_data use_device` and which matches either a DEVICE dummy or a
host
dummy. Scalars and unmapped objects keep no attribute, so a specific
taking
host scalars and device arrays is preferred over one requiring every
argument
to be on the device.
Semantics records the mapped objects on the OpenACC construct scope
rather
than on the symbols themselves, so ordinary references inside the region
still denote the host object; only argument association consults the
mapping.
The lookup walks enclosing scopes so nested data regions work, and is
skipped
entirely when the compilation contains no such mapping.
Lowering keeps the host binding in the symbol map and adds a parallel
device-binding stack populated from the `acc.data` operands. A call
argument
is rebuilt from the device binding only when the dummy is DEVICE;
objects
without a whole-object binding, such as common block members and
component
references, are left on the host path.
Only `acc data` is handled; compute constructs are unaffected.

llvm-reduce: Error on -j with MIR inputs (#226225)
Parallel chunk processing distributes work by serializing the program to
bitcode and reparsing it in each worker thread. Bitcode cannot represent
MachineFunctions, so readBitcode leaves ReducerWorkItem::MMI null and
the reparsed item reports isMIR() == false. The delta pass list is still the
MIR one, chosen from the original program, so the worker runs a MIR pass
over an item with no MachineModuleInfo and dereferences null.
This broke every MIR reduction using -j > 1, though not immediately: the
parallel path is only taken once there is more than one chunk left to
process, so the crash appeared after the first granularity increase.
Reject the combination up front instead of crashing partway through a
reduction. Supporting it would mean exchanging MIR text rather than
bitcode, and giving each worker its own TargetMachine.

[llvm-cov] Migrate gcov to OptTable (#224955)
llvm-cov gcov is the last user of cl::Grouping. Parse its options with
an OptTable that enables grouped short options, as the other
binutils-style tools do, so that cl::Grouping can be removed.
Spellings follow the other migrated tools: long options take `--` only,
so `-gcno` and `-gcda=` become `--gcno` and `--gcda=`. `--help` now
lists only gcov's options rather than every cl:: option linked into
llvm-cov, and an unknown option or a missing source file is reported
as `llvm-cov gcov: error: ...`.

`export`/`symtab` overlap by marking the duplicate entry as
`eSymbolTypeAdditional`:

[lld][MachO] Remove `__thread_ptrs` section so TLV can relocate against dynamic-lookup symbols (#221364)
lld/MachO rejects a relocation whenever `hasAttr(TLV) != sym->isTlv()`, but
`isTlv()` cannot separate "not thread-local" from "unknown", so that one
inequality rejects three unrelated cases and only one of them is ill-formed.
C++20 `constinit` made another of them common: it lets the compiler elide the
thread-local wrapper and access a cross-TU object directly ([folly 2c666105](https://github.com/facebook/folly/commit/2c666105e9a694aef7290cce3da14ed1ebf14462)),
producing a TLV relocation against a dynamic-lookup symbol. The check was also
masking a defect — `Symbol::gotIndex` is one field indexing whichever of `__got`
or `__thread_ptrs` holds the symbol — and never enforced it anyway, since
`UnwindInfoSection` and the stub paths call `in.got->addEntry` directly, so a
thread-local personality already collided on stock lld.
Both pools hold the same value, the descriptor's address, and ld-prime never
synthesizes `__thread_ptrs` at all. Make `__got` the sole non-lazy pointer
section, deleting `TlvPointerSection`, `NonLazyPointerSectionBase`,
`in.tlvPointers`, `Symbol::getTlvVA` and the indirect-symbol-table
special-casing, and collapsing `resolveGotVA`/`resolveTlvVA` into
`resolveNonLazyPtrVA`. One section, one index, so the collision becomes
unrepresentable. Input objects with a real `__thread_ptrs` section still pass
through unchanged.
The check can now say what is actually wrong: TLV relocations against
dynamic-lookup symbols and GOT, branch or unsigned relocations against
thread-locals are accepted; a TLV relocation against a symbol known not to be
thread-local still errors, and a direct relocation against an imported
thread-local gets its own diagnostic. Two tests asserted a diagnostic ld64 does
not raise, so they keep their inputs, move out of `invalid/`, and assert the new
behaviour.

[InstCombine] Fold variable extract of a constant-strided pointer vector (#217078)
A vector built from pointers that all point into the same object at a
constant stride is a table of addresses, so a variable extract from it
is address arithmetic:
%v0 = insertelement <4 x ptr> poison, ptr %b, i64 0
%v1 = insertelement <4 x ptr> %v0, ptr %b + 8, i64 1
%v2 = insertelement <4 x ptr> %v1, ptr %b + 16, i64 2
%v3 = insertelement <4 x ptr> %v2, ptr %b + 24, i64 3
%r = extractelement <4 x ptr> %v3, i32 %i
-->
%r = getelementptr i8, ptr %b, i64 %i * 8
Fold it to a single GEP. Every element must be reachable from one base
pointer at a constant byte offset, every lane of the vector must be
defined, and the offsets must form an arithmetic sequence; otherwise the
pattern is left alone.

[mlir][bufferization] Relax happens-before analysis (#223777)
On unstructured control-flow, the one-shot analysis is rather
conservative in regards to computing RaW conflicts, requiring strict
dominance which may not always be satisfied.
Relax this requirement to allow more cases to not be marked as
conflicting. Notably, readers/writers within a region that contains a
"diamond" or multiple loops are now handled.
This is a simpler version of
https://github.com/llvm/llvm-project/pull/223006 without the CFGLoopInfo
analysis, meaning it is a bit more conservative when analyzing regions
with nested loops.

https://discourse.llvm.org/t/rfc-make-myst-markdown-the-llvm-docs-format-rip-rest/90840/37
I'm assuming that other distributions are either going to be able to
install the necessary Python modules that we depend on (myst_parser
etc), or will use this man page package if they need it. Therefore, I think we
can remove this enum and associated complexity.

[HLSL] Add `InterlockedExchange` function and resource methods (#222161)
This PR adds the `InterlockedExchange` standalone function and resource
methods. The operation lowers to `atomicrmw xchg`.
`InterlockedExchange` is the first interlocked operation that reports
the
previous value. It takes that value through an `original_value`
reference
parameter, so this PR adds a `RequiresOriginalValue` flag to
`HLSLBuiltinTypeDeclBuilder` and a matching overload shape to
`HLSLExternalSemaSource`. The later compare operations reuse both.
The float overload of `InterlockedExchange` follows in a separate PR in
this
stack. This PR covers the integer overloads alone, so it links
https://github.com/llvm/llvm-project/issues/99129 without closing it.

[DirectX] Support `cmpxchg` on buffer resources in DXIL lowering (#222162)
This PR is a backend change alone. It teaches DXIL lowering to handle a
`cmpxchg` on a buffer resource pointer, which the
`InterlockedCompareStore`
and `InterlockedCompareExchange` PRs above it in this stack need.
The PR adds:
- the `llvm.dx.resource.atomic.compare.exchange` intrinsic,
- its DXIL operation and op lowering,
- the `DXILResourceAccess` handling that turns a `cmpxchg` on a value
returned by `llvm.dx.resource.getpointer` into that intrinsic.
DXIL has no atomic compare exchange for texture resources, so the pass
reports an error for them. A test covers that path.
There is no Clang change here, and no HLSL function becomes available.

[lldb] Add plugin for Clang offload bundle object container (#222362)
## Summary
Clang supports embedding binaries using the clang offload bundler:
https://clang.llvm.org/docs/ClangOffloadBundler.html
This patch creates an ObjectContainer plug-in that allows us to get the
contained binaries within any executable.
### why we need this?
AMD/HIP host binaries may contain a .hip_fatbin section holding a Clang
offload bundle with one or more AMDGPU ELF code objects, typically for
different GPU architectures. Each ELF code object can contain multiple
ml kernels.
### Test
Added tests for the logic.
NOTE: Caching was intentionally left out to keep the upstream initial
implementation simple; i will add it as a followup.

[yaml2obj] Migrate to OptTable (#224964)
yaml2obj is one of three tools that parse with
cl::ParseCommandLineOptions(LongOptionsUseDoubleDash=true). Parse its
options with an OptTable instead, so that the mode can be removed from
cl::. Spellings follow the other migrated tools: -D<macro>=<v> and
-D <macro>=<v>, -o<file> and -o <file>, --docnum=<n> and --docnum <n>,
--max-size likewise, -E, -h/--help and --version. `-o=<file>` is no
longer accepted; the tests that used it are updated. `--help` lists
only yaml2obj's options.

[SystemZ] Fix zero length PR section for zero size BSS globals (#225863)
PR sections must have a non zero length. This was already handled for
ADA sections via requiresNonZeroLength(), but not for BSS globals
declared with zero size. This change extends the existing inflation to
also cover BSS PR sections.
