[PowerPC] Remove itinerary IIC_LdStDCBA (#207227)
The itinerary IIC_LdStDCBA is defined and used in scheduling models, but
no instruction is assigned to it. However, since the instruction is
basically retired (not part of the portable Power ISA), and all
scheduling models model it similar to IIC_LdStDCBF, the itinerary can be
removed.

C++ and C23 continue to use `[[clang::lifetimebound]]` as the default

When no explicit lifetimebound macro is configured, pre-C23 C only looks
for `__attribute__((lifetimebound))`, C++ and C23 keep looking for
`[[clang::lifetimebound]]` macros first, then
`__attribute__((lifetimebound))`.

[Instrumentor] Fix indirect arguments on gpu targets (#209835)
When an argument is passed indirectly,
`IRTCallDescription::createLLVMCall` spills it into a temporary alloca
and passes that alloca address to the runtime call. The alloca is
created in the target's alloca address space. On GPUs it is not address
space 0, which is what the runtime expects for indirect parameters. The
alloca pointer was passed as the argument, so its type didn't match the
call's declared parameter type, causing a "bad signature" assertion in
`CallInst::init` when instrumenting GPU code that requires indirection.
The solution is therefore to cast this pointer to address space 0 before
passing it the the instrumentor call.

[lldb][Windows] Don't let the inferior inherit the --pipe handle (#207024)
`lldb-server` writes its listening socket id to the `--pipe` handle and
then closes it. The parent process that spawned it reads the pipe until
EOF purely as a synchronization point (`"the server is now listening"`).
On Windows the inferior is launched with `bInheritHandles=TRUE` (it
needs the ConPTY handles), so it also inherited the pipe's write end.
That kept the write end open after `lldb-server` closed its own handle,
so the parent never saw EOF: it blocked until its read timeout and the
client's connection handshake timed out first.
This patch clears `HANDLE_FLAG_INHERIT` on the `--pipe` handle so the
inferior cannot keep the write end open, while leaving it valid for
lldb-server's own use.

[CycleInfo] Store cycles in a flat preorder array. NFC (#209981)
Store cycles by value in one array in cycle-forest preorder, each cycle
immediately followed by its descendants, instead of heap-allocating each
cycle and holding its children in a std::vector<std::unique_ptr<>>.
Child and top-level iteration become pointer arithmetic that skips a
subtree via a new NumDescendants count, and sizeof(GenericCycle) drops
from 72 to 48. GenericCycleInfoCompute builds the forest with temporary
nodes, then flatten() moves it into the array.
GenericCycle still exposes raw pointers into this array. The eventual
goal is to replace them with an opaque handle, so all access goes
through GenericCycleInfo and the storage stays an implementation detail.

[CIR] Add support for the IdiomRecognizer pass (#208854)
This patch adds the `IdiomRecognizer` pass, which raises calls to known
standard library functions into dedicated operations that later passes
can optimize. The implementation follows the ClangIR incubator, and
upstream had only the pass skeleton and the frontend wiring.
The pass recognizes the standard find algorithm and raises it to the new
operation `cir.std.find`. A call is raised when its callee carries the
matching identity tag, the argument count and the types line up, the
callee is not variadic, and the call is not `musttail`. LoweringPrepare
lowers the operation back to the original call with its attributes, so
behavior never changes when no transform fires.
The tag is the new `func_identity` form under the `func_info` union on
`cir.func`. It holds one entry from an enum naming the entities the
recognizer knows, so the tag itself carries no names. `CIRGen` attaches
it by the plain name, the std membership with inline namespaces looked
through, and whether the function is free, so members, static members,
operators, and functions outside std never match, while the recognizer
checks the shape of each call.
The pass reads facts from the operations alone, so the AST requirement
and its wiring are gone, the pass is registered with `cir-opt`, and a
test drives it over parsed CIR assembly.

PPC: Avoid constructing TargetTransformInfo in isHardwareLoopProfitable (#209972)
PPCTTIImpl::isHardwareLoopProfitable constructed a throwaway
TargetTransformInfo only to call CodeMetrics::analyzeBasicBlock. TTI
may contain pipeline configuration state, and should only be queried
from the PassManager. It was also particularly ugly to construct one
here given that we're inside a TTIImpl.
Most of what analyzeBasicBlock computes was not used here. Directly
sum the instruction code size costs, which was the only used component
of the analysis.

[flang][OpenACC] Allow blanks around ':' in a gang-arg (#210089)
The parsers for the STATIC, DIM, and NUM forms of an OpenACC gang-arg
used the token strings "STATIC: ", "DIM: ", and "NUM: ", none of which
permit a blank between the keyword and the ':' separator. A space in a
TokenStringMatch pattern is the only place a blank is accepted in the
source (outside the leading/trailing skip), so a directive such as
!$acc loop gang(static : 1)
was rejected with "expected end of OpenACC directive", even though
free-form Fortran allows optional blanks around the separator.
Move the blank in each token string to before the ':' ("STATIC :", etc.)
so zero or more blanks are accepted on either side of the separator. The
_tok form keeps the blank optional, so the no-space spelling still
parses without a warning.
Add parser/unparse coverage for the spaced spellings of the static, dim,
and num gang arguments.

[clang][Modules] Adding Specific Diagnostics when a Finalized PCM is Out-of-date due to Input File Changes (#209857)
We have good diagnostics coverage when a pcm cannot be dropped in
`ASTReader::readASTCore`, because we call `canRecoverFromOutOfDate` to
check if the pcm is finalized or not. This check is missing for input
file changes.
This PR fixes the diagnostics, so we do not fall to the generic error
`err_module_rebuild_finalized`, which is hard to reason and act on.

[clang][DependencyScanning] Logging Dependency Scanning Events (#195896)
This PR sets up an `AtomicLineLogger` (added by
https://github.com/llvm/llvm-project/pull/205395) to log the sequence of
dependency scanning events. The logging is triggered by a new `LogPath`
option in `DependencyScanningServiceOptions`. This PR adds an option
`-log-path=` to `clang-scan-deps` to trigger the log.
We are logging 16 events during dependency scanning.

|-------|-----------|------|
| `starting scanning command: <args>` | `DependencyScanningWorker.cpp` |

dropped (validation failed) |
| `pcm_not_dropped: <pcm path>` | `InMemoryModuleCache::tryToDropPCM` |
PCM not dropped (validation failed, but already final) |
In addition to checking the logger's functionality,
`clang/test/ClangScanDeps/logging-simple.c` checks against the change
committed by https://github.com/llvm/llvm-project/pull/177062. Without
https://github.com/llvm/llvm-project/pull/177062,
`clang/test/ClangScanDeps/logging-simple.c` fails.
This implementation adds a single instance of `AtomicLineLogger` to the
`DependencyScanningService`. Most of the plumbing goes into the
`ModuleCache` and its derived classes.

[NFC][Clang][PowerPC] Fix suspicious unsequenced volatile accesses in codegen tests (#199338)
When trying to add new Sema check in PR
https://github.com/llvm/llvm-project/pull/180955 some tests failed.
The following pattern is observed in these tests:
```
volatile x;
x = __builtinXXX(x, x, x);
```
For C and C++ standards order of evaluate funcall argument is
unsequence(or indeterminate sequence) and unsequence access for same
volatile variable is UB(because read volatile qualified variable is
side-effects).
As far as I undestand, unsequenced accesses is unwanted and new warning
is correct.

This commit adds a128 load, store and compare_exchange to the Go

operate on 16-byte values.
The SANITIZER_GO macro was gating a128 and is now lifted. Based on the
__TSAN_HAS_INT128 macro definition, the only architecture excluded by it
that intersects with [Go race support
](https://go.dev/doc/articles/race_detector#Requirements) is s390x.

[AMDGPU] Fold constant offset into SV form addressing in SVS frame index fallback (#208629)
Depends on #208624 (which depends on #208612).
In the SVS fallback path of `SIRegisterInfo::eliminateFrameIndex` for
flat scratch, the scratch address was materialized by moving the full
frame offset into the scavenged vaddr VGPR and forcing the
instruction's immediate offset to `0`, which also silently dropped
any pre-existing immediate offset on the instruction.
This splits the full constant offset with `TII->splitFlatOffset`, folding
as much as possible into the SV form instruction's immediate offset
field and materializing only the remainder (plus the frame register,
if any) into the vaddr VGPR.
Test: adds `scratch_{store,load}_svs_split_offset` to
`eliminate-frame-index-flat-scratch-svs.mir` (non-zero instruction
offset, now preserved and folded) and regenerates the existing checks.

[sanitizer_common] fix shadowed ret hiding symbolizer read failures. (#209971)
The inner `bool ret` from ReadFromFile shadowed the outer one that is
returned, so a dead/closed symbolizer (0-byte read or read error) was
reported as success: SendCommand never restarted the crashed process,
and the addr2line path aborted on a CHECK over an empty buffer.
Regression from acfeb1a6c244. Add a regression test that feeds an EOF fd
through ReadFromSymbolizer and expects failure.

this with local builds, so it's unclear what the root cause is.
To help investigate similar failures in the future, we're adding a test

should fail too, and provide way more info helping debugging than other

[clang][win] Fix __global_delete wrappers for Arm64EC and cross-TU ::delete (#209585)
PR #188372 made Clang's MSVC-ABI deleting-destructor path route global
deletes
through compiler-generated __global_delete / __global_array_delete
wrappers
instead of referencing ::operator delete directly. This lets a deleting
destructor be emitted in environments (e.g. kernel mode) where no global
::operator delete exists: each wrapper defaults to a trapping
__empty_global_delete fallback, and a real forwarding body that calls
::operator delete is materialized only when the program actually uses
::delete.
This change refines how those wrappers and their fallbacks are emitted,
fixing
two problems that made the #188372 mechanism fail in practice.
New behavior:
- The trapping fallback is now emitted as a weak GlobalAlias to
__empty_global_delete rather than via an /alternatename directive. This
lowers
to a COFF weak-external-with-default -- exactly what MSVC emits -- so a
real
__global_delete defined in any TU overrides the fallback in every other
TU at
link time.
- A ::delete expression now registers the wrapper for its resolved
global
operator delete directly (in EmitCXXDeleteExpr), so the strong
forwarding body
is emitted in that TU regardless of where the class's deleting
destructor is
defined. This matches MSVC, which emits the forwarder at every ::delete
site.
Bugs fixed:
1. Arm64EC (miscompile -> LNK2019). /alternatename only names the plain
symbol,
not the backend-generated "$$h" hybrid EC symbol referenced by the exit
thunk, so Arm64EC images left __global_delete$exit_thunk unresolved. The
weak
GlobalAlias correctly produces the "$$h" symbol, exit thunk, and plain
alias
(verified on both x64 and Arm64EC).
2. Cross-TU ::delete (runtime crash). Previously the forwarding body was
only
emitted in a TU that *both* emitted a matching vector deleting
destructor and
contained a ::delete. A TU that only performed `::delete p` -- with the
class
defined elsewhere -- emitted no forwarder, so nothing overrode the
weak-alias
trap and the program executed a trapping __empty_global_delete at
runtime
(STATUS_ILLEGAL_INSTRUCTION). Registering the wrapper at the ::delete
site
fixes this.
To share wrapper-creation logic between the deleting-destructor path and
the
delete-expression path, getOrCreateMSVCGlobalDeleteWrapper is promoted
from a
static helper in CGClass.cpp to a CodeGenModule method.
Verified end-to-end: a weak alias in one TU and a strong forwarder in
another
resolve to the forwarder under both lld-link and MSVC link.exe, and the
previously-crashing delete-only TU now runs cleanly.

[Hexagon] Fix HexagonRDFOpt hang during live-in recomputation (#209986)
After HexagonRDFOpt, the compiler recomputed live-in registers for every
block in one batch. On large inputs (e.g. kernel builds) this was slow,
and on some functions each pass changed the live-in values of other
blocks, triggering more passes until the compiler hung (PR #207422).
Fix: process blocks one at a time in post-order (successors before
predecessors) and stop as soon as nothing changes. Add a pass limit as a
safety net to keep compile time bounded in all cases.

[CIR] Fix use-after-free when emitting ternary with a throw-expression arm (#208850)
Fixes #208848.
When a conditional operator arm is a noreturn expression, such as
`throw`, `VisitAbstractConditionalOperator` saved an insertion point in
the empty dead-code block created after the expression. The intent was
to insert a `cir.yield` later, once the types of both arms were known.
However, `LexicalScope::cleanup()` removes that empty block when the
arm’s scope exits, leaving the deferred insertion point with a dangling
block pointer.
Avoid saving the insertion point for noreturn arms. These regions
already terminate with `cir.unreachable` and do not require a
`cir.yield`. The CIR verifier accepts ternary regions that terminate
with `cir.unreachable`.
Extended `ternary-throw.cpp` with scalar-rvalue cases covering `throw`
in either arm and in both arms. The existing tests only covered glvalue
conditionals, which take the LValue emission path and never reach this
code.

[lldb] Produce generic results for DWARF relational operations (#210122)
DWARF relational operations produce a generic result, whose width is the
target address size. LLDB currently assigns the C++ `bool` comparison
result directly to `Scalar`; because `Scalar` has no `bool` constructor,
this creates a 32-bit integer even on 64-bit targets.
The stricter binary operand checks added in #201288 exposed this in
x86-64 `_sigtramp` CFI. A later `DW_OP_plus` combines a 64-bit generic
address with the 32-bit relational result, so evaluation fails and
signal-frame unwinding stops. The generic-operand relaxation in #209641
does not cover this case because the relational result is narrower than
the address size.
Convert the results of `DW_OP_eq`, `DW_OP_ge`, `DW_OP_gt`, `DW_OP_le`,
`DW_OP_lt`, and `DW_OP_ne` through the existing `to_generic` helper.
## Testing
Add a unit test that evaluates each relational opcode with an 8-byte
address size and then consumes its result with `DW_OP_plus`.

[tsan] Enable __TSAN_HAS_INT128 on s390x and mips64 (#197319)
The s390x exclusion was added in
https://github.com/llvm/llvm-project/commit/b17673816d7f65e07015489993b22049e36b04db
(https://reviews.llvm.org/D105629)
citing lack of hardware 128-bit atomics. s390x does have the CDSG
instruction,
but `alignof(__int128) == 8` on the s390x psABI while CDSG requires
16-byte
alignment, so Clang does not define
`__GCC_HAVE_SYNC_COMPARE_AND_SWAP_16` for
this target. The mips64 exclusion has been present since
`__TSAN_HAS_INT128` was
introduced in
https://github.com/llvm/llvm-project/commit/06bbca9ec4bbc5a103c94c4973797ea4ddf944b5
(https://reviews.llvm.org/D18543) with no documented
rationale. Clang similarly does not define
`__GCC_HAVE_SYNC_COMPARE_AND_SWAP_16`
for mips64.
Both exclusions are unnecessary. When
`__GCC_HAVE_SYNC_COMPARE_AND_SWAP_16` is
not defined, all a128 operations use the SpinMutex-based emulation path,
which
serializes 128-bit accesses under a global lock without requiring any
hardware
CAS16 support.
Verified with Clang (targets: s390x-linux-gnu, mips64-linux-gnuabi64,
mips64el-linux-gnuabi64): all three produce the full set of 12
`__tsan_atomic128_*` symbols with zero `__sync_*_16 / __atomic_*_16`
libcall references.
Runtime testing has not been performed as I lack access to these
architectures.

[TableGen] Short-circuit !cond operator (#208942)
Fixes #163213
TableGen `!cond` operator currently resolves all subsequent conditions
and values even if it already found a condition that resolves to `true`.
This change short-circuits on the first `true` resolution found
iterating from left to right. It folds a new `CondOpInit` with only the
conditions and values that have already been resolved, including the
current condition and value.

[flang][cuda] Use managed allocation for saved locals (#210133)
Example:
```fortran
subroutine work
real, allocatable, save :: q(:)
allocate(q(10))
end
```
`SAVE` gives the local allocatable descriptor static storage. Implicitly
attributing it as Unified causes allocation to look it up as a
registered CUDA global, but no device symbol is registered for the
descriptor.
Fix: use Managed attribution for saved subprogram-local allocatables and
pointers, avoiding the invalid CUDA symbol lookup.

[Clang][Sema] Reland -Wstringop-overread with computeDependence fix (#208012)
Reland #183004 and follow-up #205201 (reverted in #207840) which adds `-Wstringop-overread` to warn when memory functions `memcpy`, `memmove`, `memcmp`, and other related builtins read more bytes than the source buffer size.
The revert was due to a crash when a memory function is called on `&x` where `x` is a static constexpr local inside a template. The original PR exposed a bug in `computeDependence(UnaryOperator*)` where only the value-dependence bit is set for this case, when the instantiation-dependence bit should also be set. This is the root cause behind the crash.
Fix `computeDependence` to properly set both value and instantiation-dependence bits, and add a regression for this crash via `warn-stringop-overread.c`.

Note that `gettimeofday` is removed removed from POSIX-2024, but let's
keep it available for now, since there's fair amount of existing code
that still uses it.

[WebAssembly] Don't assert on a non-zero call_indirect table index (#210120)
WebAssemblyInstPrinter::printInst asserted that a non-symbol table
operand of call_indirect is the immediate 0, on the assumption that only
MVP single-table compilation units reach the printer. That is true for
code generated by the compiler, but the printer is shared by the
disassembler.
The disassembler must produce output for any byte sequence it is pointed
at and shouldn't abort on the operand values it decodes. A non-zero
immediate table index is both a valid encoding, from a multi-table
module, and a routine result of best-effort disassembly of a range that
is not all code, which is how I hit this in LLDB.
Print the table operand when it is a symbol or a non-zero immediate, and
omit it only for the implicit table 0. This makes the output lossless
and unambiguous, matching how a table symbol is already printed. MVP and
table-symbol output are unchanged, so there is no effect on the
compiler's assembly.

gn build: Support building debug binaries from a release build directory.
This change makes it so that all binaries in `bin` have a corresponding
debug binary target `$TARGET.dbg` that will build a debug binary in
`bin.dbg/$TARGET`. This is implemented using a separate toolchain for
the debug builds. This has the following advantages over a separate
debug build directory:
1. Can use release mode tblgen to generate code for the debug build
binaries, which speeds up the build because it can run tblgen faster as
well as being able to reuse the tblgen binary from the release build.
2. Can reuse runtimes built in the release mode clang's resource
directory, avoiding the need to build them again with a slow debug
build of clang.

[orc-rt] Add asCCallback utility -- C callbacks for methods. (#210048)
Adds orc_rt::asCCallback<&Class::method>, which produces a C-ABI
function pointer that forwards to the given member function. The first
parameter of the generated trampoline is an opaque context pointer (
void * for non-const methods, const void * for const methods) that is
cast back to the class type and used as the receiver:
struct Counter {
void inc(int N) { Count += N; }
int Count = 0;
};
Counter C;
void (*CB)(void *, int) = asCCallback<&Counter::inc>;
CB(asCCallbackContext<&Counter::inc>(C), 2); // C.Count == 2
asCCallbackContext produces the matching context pointer via
static_cast, so any base-class offset is applied and const-ness is
preserved; pairing it with asCCallback by the same method keeps things
correct under inheritance and const-qualification. (A raw cast of &C
would give the trampoline the wrong `this` when method's class is a base
at a non-zero offset.)
Specializations cover the const x noexcept combinations. The trampoline
is always noexcept -- a C caller cannot unwind a C++ exception, so an
escaping one terminates -- and return/argument types are restricted to
C-compatible (non-reference, trivially copyable) types via
static_assert.

[BOLT] Add fdata symbols mode (#209932)
Add a new fdata profile mode accepting symbol names as-is.
It addresses the UX gap surfaced by #208313 that all methods of selecting
functions to process (symbolized profile types, `-funcs*` options) expect
disambiguated local symbols.
Introduce fdata mode activated by a `symbols` header line, where each subsequent
line is a (mangled) symbol name. The names are matched against restored function
names (with disambiguation suffix stripped), and every matching function gets an
execution count of 1.
This can be used to drive selective instrumentation (`--instrument-hot-only`) or
basic linker-script style optimizations.
Symbols are stored as branch entry data so matching reuses the existing default
branch profile path.
Test Plan:
Update docs/profiles.md and add profile-symbols-mode.s

[lldb/script] Migrate frame recognizers onto ScriptedPythonInterface (#209805)
Give `frame recognizer add -l` a formal
ScriptedStackFrameRecognizerInterface, matching the architecture already
used by ScriptedProcess, ScriptedBreakpoint, etc.: a C++ interface
header, a Python-backed implementation built on
ScriptedPythonInterface's CreatePluginObject/Dispatch machinery,
PluginManager registration, and a generatable Python ABC template
(scripted_stackframe_recognizer.py).
get_recognized_arguments' documented contract returns a plain list of
lldb.SBValue (not an lldb.SBValueList), so it bypasses the generic
Dispatch<ValueObjectListSP>() extractor and calls the SWIG bridge
directly, matching the legacy behavior exactly.
ScriptedStackFrameRecognizer now holds a single interface object created
once in its constructor and reused across every RecognizeFrame() call,
same lifecycle as before.

Fixes https://github.com/llvm/llvm-project/issues/64706
Wire per function x86 AVX ABI level into CodeGen arrangement methods so
__attribute(__target("avx"))) / __attribute(__target("avx512f"))) on
methods, ctors, and free-functions affects ABI lowering consistently.
Specifically:
- Added X86AVXABILevel member to CGFunctionInfo.
- Populated X86AVXABILevel member in CGFunctionInfo objects via
arrangement methods declared in CodeGenTypes.h.
- Respect CGFunctionInfo AVX Level in X86_64ABIInfo::computeInfo.
- Add/extend regression tests for:
- free-function target-attribute AVX ABI lowering
- C++ method/ctor target-attribute AVX ABI lowering
- PS4/PS5 legacy ABI behavior (no per-function AVX ABI change)

[LoongArch] Fix invalid VEXTH combines for unsupported type extensions (#209725)
`performEXTENDCombine` could form `VEXTH`/`VEXTH_U` nodes for
unsupported type combinations, such as extending `v8i8` to `v8i32` or
`v2i64` to `v2i128`. These illegal nodes would later reach instruction
selection and trigger backend failures:
* `Cannot select: LoongArchISD::VEXTH`
* `Don't know how to legalize this operation`
Prevent these combines from firing by verifying that the destination
type is legal and has exactly twice the total bit width of the source
before forming a `VEXTH`/`VEXTH_U` node.
Apply the same checks to `performSHLCombine` for consistency.

[flang][cuda] Managed backing for -gpu=unified allocatables/pointers (#210149)
Under `-gpu=unified`, allocatables and pointers with no explicit CUDA data
attribute must be reachable from the device. Back them with CUDA managed
memory by selecting the unified allocator index at the ALLOCATE site (in
lowering), instead of stamping an implicit `Unified`/`Managed` CUDA data attribute
on the symbol in the frontend — the approach introduced in PR #209292.
This is necessary because attributing the symbol in the frontend routed every
plain allocatable/pointer through the CUDA Fortran managed descriptor
pipeline (constructor registration, `cuf.allocate`/`cuf.free`), which added
per-`ALLOCATE` overhead, forced special-casing for objects that may not legally carry a
CUDA attribute (COMMON members, derived-type components, module globals), and
changed symbol semantics used well beyond allocation. Choosing the allocator
index at the `ALLOCATE` site keeps the object a plain host allocatable/pointer while
the storage still comes from the managed allocator.

Session::managedCodeTaskGroup() returned the raw

group's full interface -- including close() and addOnComplete() -- to
callers, even though those operations are reserved for the Session.
Add TaskGroup::TokenSource, a strong handle whose sole role is to serve
as an argument to the TaskGroup::Token constructor. Session now exposes
managedCodeTokenSource() in its place, so clients can acquire tokens (to
keep managed code alive across shutdown) without gaining the ability to
close the group or register completion callbacks.

Add a LIT test that baselines the current lowering of parenthesized
initial values in fir.global initializer regions. Today a parenthesized
scalar or derived constant survives constant folding as a Parentheses
node and is lowered to a fir.no_reassoc operation inside the global init
region, while parentheses around characters, array named-constants, and
structure-constructor components are stripped before lowering.
This test pins that behavior so that an upcoming change to the
initializer-lowering path shows its behavior delta explicitly and has a
regression guard.

libraries to BUILD.bazel:
- accept
- accept4
- bind
- connect
- getpeername
- getsockname
- listen
- sockatmark
I'm also enabling the unit tests for these functions. Running AF_UNIX
socket tests under Bazel ran into a problem where the absolute path to
the test sandbox directory exceeds the 108-byte limit of
sockaddr_un::sun_path. To work around that, I added a TestDirectoryScope
helper that temporarily chdirs into the test directory so the tests can
use short relative filenames, and restores the original working
directory on exit.

This change requires for upcoming raw buffer load/store/atomic builtins.
Those builtins `__builtin_amdgcn_raw_buffer_load/store_b*,
__builtin_amdgcn_raw_ptr_buffer_atomic_*` take a
`__amdgpu_buffer_rsrc_t` as operand, and the corresponding LLVM

[fakeflang] Also detect CMakeTestGNU.c (#210175)
Two fixes when using CMake < 3.28 after #209482:
* In addition to `flang`, also recognize `fakeflang` to determine
whether any workaround for CMake not completely supporting Flang is
needed. `fakeflang` is used as a shim in #209482.
* For CMake < 3.24, CMake does not reognize Flang at all and tries other
methods to detect to the compiler, including the file `CMakeTestGNU.c`.
Make `fakeflang` recognize it as a probe attempt.
This should fix the
[openmp-offload-amdgpu-clang-flang](https://lab.llvm.org/buildbot/#/builders/67)
buildbot. The buildbot is currently upgrade to a newer CMake version,
and the minimum required version of CMake will become 3.31 soon.

[lldb] Fix tsan error in SymbolLocatorDebugSymbols (#209698)
g_dlsym_DBGCopyFullDSYMURLForUUID and g_dlsym_DBGCopyDSYMPropertyLists
are two globals that are lazily initialized when first used. TSan
complains that this lazy init code is not thread-safe as there is no
synchronization mechanism. In practice, the only race that can happen
here is that we initialize the same values concurrently, which should be
'safe' on any platform.
This patch moves the initialization code into a static local that
returns a const object. This makes this code thread-safe by construction
and fixes the TSan error.
It also fixes that we keep calling dlopen if the initialization fails.
That is, the `g_dlsym_DBGCopyFullDSYMURLForUUID == nullptr` will always
be true on systems where the framework doesn't exist, so this code will
try loading it on every function call and fail.

[flang][PFT] record every target of an assigned GO TO (#210065)
Assigned GO TO (`go to v [, (l1, l2, ...)]`) is the third multiway
branch in the language, alongside the computed GO TO and arithmetic IF
that were addressed in PR #210012. Its PFTBuilder handler previously
did:
[&](const parser::AssignedGotoStmt &) {
eval.isUnstructured = true;
markSuccessorAsNewBlock(eval);
},
i.e. it recorded no branch targets at all -- neither `controlSuccessor`
nor `extraControlSuccessors` was populated.
Handle the assigned GO TO the same way PR #210012 handles the computed
GO TO and arithmetic IF: iterate every possible target and call
`markBranchTarget(eval, label)` for each, so that `controlSuccessor`
receives the first and `extraControlSuccessors` receives the rest.

[LTO] Sort DefinedGlobals in LTO cache key (#210025)
Sort the DefindeGlobals by GUID when computing the LTO cache key, to
avoid making the cache key dependent on the insertion order. This fixes
large compile-time regressions in rust incremental builds.
Alternatively one could make collectDefinedGVSummariesPerModule() work
on the sortedRange(), but as that is also used in other places, it
probably makes sense to sort locally.

[lldb][test] Handle potential compiler differences in TestEmptyFuncThreadStepOut.py (#210050)
Fixes #195958
It was reported that this test sometimes failed in CI because lldb would
step out to line 6 instead of line 7.
Jim Ingham expained on the issue that both could be valid locations
(https://github.com/llvm/llvm-project/issues/195958#issuecomment-4384269846).
There's no garauntee that "step out" would go to the source line after
the call you step out of. All it does is go to the first location
outside of the call. If the compiler so chose, that could be on the same
line as the call.
I was not able to reproduce this failure mode, but I think it was
happening in CI before, and is possible. So I've made the test accept
line 6 or 7. Anything further than that we've gone too far and the test
will fail.

We should use unknwn.h and windows.h instead of Unknwn.h and Windows.h
because Linux and other non‑Windows systems treat filenames as
case‑sensitive. Windows does not, so mixed‑case includes work there but
break elsewhere. Both mingw‑w64‑crt and windows‑msvc‑sysroot provide all
Windows headers in fully lowercase, so using the lowercase forms ensures
consistent cross‑platform builds.

[lldb][NativePDB] Use active bits for constant width (#196104)
Static constants with bit widths less than 16 (e.g. char/unsigned char)
in classes were not available. These constants are still encoded with 16
bits
([here](https://github.com/llvm/llvm-project/blob/dd145eb8997878143f648a7601741f6409330963/llvm/lib/DebugInfo/CodeView/CodeViewRecordIO.cpp#L341-L343))
even though they only need less bits. When we tried to create an
initializer for them, we'd check if the bit width (=16) was small enough
to fit into the target (<16). This would fail.
This was a problem in the following code:
```cpp
struct Foo {
// width(unsigned char) = 8, but 255 was encoded and read as 16 bit
static constexpr unsigned char u8_max = 255;
};
```
This PR fixes the issue by using `APSInt::getActiveBits` for unsigned
types and `APSInt::getSignificantBits` for signed types. They get the
number of bits required to encode the value. For example a constant 64
would need 7 bits in unsigned and 8 bits in signed types.

[Clang][Sema] Fix crash in UnresolvedMemberExpr check (#209792)
This closes https://github.com/llvm/llvm-project/issues/209427
The test currently crashes because while iterating over the candidate
members of an unresolved member expression, `decl` is a `UsingShadowDecl`
with underlying decl as `UnresolvedUsingValueDecl`.
The current `isa<UnresolvedUsingValueDecl>(decl)` guard only checks the
outer `UsingShadowDecl` and misses the unresolved-using decl hidden
inside it, so `getAsFunction()` returns nullptr and
`cast<CXXMethodDecl>(nullptr)` asserts.
This patch checks the `UnresolvedUsingValueDecl` inside by calling
`getUnderlyingDecl()` before the guard.
This used to happen before a2794f9f363361f87a3538b90b78ff13381d5ce1.

[KnownBits] Use X < Y identity and umin(MaxX, MaxY - 1) bound in urem (#210262)
Tightens `KnownBits::urem` with the two facts `ConstantRange::urem`
already uses:
- `L % R == L` when `MaxL < MinR`: return the LHS bits unchanged. This
can propagate known one bits, which the current leading-zeros-only
reasoning never produces.
- `L % R <= umin(MaxL, MaxR - 1)`, since a zero divisor is UB: keep that
bound's leading zeros. This is one bit stronger than the per-operand
leading-zero count when `MaxR` is a power of two, and together with
`remGetLowBits` it subsumes the power-of-two-constant special case,
which is removed.
Soundness is covered by the existing exhaustive unit test (widths 1 and
4; additionally brute-forced at width 5). Across all 6480 valid width-4
KnownBits pairs, non-optimal results drop from 3332 to 2090. The
residual is number-theoretic (e.g. the exact value of `10 % 3`), out of
reach of leading-bit/range reasoning, so `CheckOptimality` stays off for
urem, as for udiv (#209360).

[Clang][Driver] Fix compiler-rt library directory for cygwin (#208925)
If compiler-rt is built with `LLVM_ENABLE_PER_TARGET_RUNTIME_DIR=OFF`,
its search directory is incorrect.
Specifically, `ToolChain::getOSLibName()` returns `windows` instead of
`cygwin` in a Cygwin environment, due to falling back to getOS(). This
results in a link error against compiler-rt.
This patch makes `getOSLibName()` return `cygwin`, ensuring that
compiler-rt is linked correctly.

[SCEV] Try to fold ZExt/SExt of AddRec before existing lookup. (#208805)
Move AddRec fold for ZExt & SExt before existing SCEV lookup. This can
improve results, when we constructed SCEV for a ZExt/SExt during earlier
analysis and flags on the operand AddRec have not been
refined/strengthend yet.
This improves results in some cases and fixes a regression here:
https://github.com/dtcxzyw/llvm-opt-benchmark-nightly/pull/654#discussion_r3554885279.
On a large C/C++ corpus with 32k bitcode files, ~2% more IVs get
widened, removing a large number of ZExt instructions.

The pattern for TCRETURNmi has a IsNotPIC predicate, but the

PatFrag is evaluated first, so we can't assert that PIC is disabled
here. We should just return false in that case.

[LLVM][SVE] Add MachineInst pass to coalesce PTRUE instructions. (#204820)
SVE predicate registers contain a bit for each byte of a data register.
When operating on bigger element types the overlaping predicate bits are
grouped together but typically only the least-significant-bit is read as
part of the operation. This means the value of the other bits does not
affect the operation, making it possible to use the result of PTRUE for
a larger element typed operation, assuming the predicate patterns are
equivalent. For example:
ADD_S (PTRUE_H 31), Z0, Z1 == ADD_S (PTRUE_S 31), Z0, Z1
AArch64PTrueCoalescingPass uses this fact to reduce the number of PTRUE
instructions in a function, with the general trend towards needing a
single PTRUE based on the smallest element type in use.
NOTE: The pass will be enabled by default using a dedicated PR to make
it easier to revert if something goes wrong.

Added by 3bea7306e8669f94bacafae68748a9139cfc0b98.
We now require GCC >= 7.4 so it can be removed.
I tested a standalone reproducer with GCC 7.3 and
clang 5. Neither have the problem.
https://godbolt.org/z/3zKrT9c8s
Standalone reproducer:
```
struct Base {
Base(int) {}
};
struct Derived : virtual Base {
#ifdef WORKAROUND
Derived(int a): Base(a) {}
#endif
virtual void g() = 0;
};
struct Final : Derived {
Final(int n) : Base(n)
#ifdef WORKAROUND
, Derived(n)
#endif
{}
void g() override {}
};
