[clang][CodeGen] Emit prefetch hints and frame address depth as i32 (#221477)
The hint operands of `llvm.prefetch` and the depth operand of
`llvm.frameaddress` and `llvm.returnaddress` are declared as i32, but
clang emitted the values at the width of the C argument's type.
`__builtin_prefetch` is declared with a variadic prototype, `void(void
const*, ...)`, so its hint arguments are never converted to a parameter
type; only the default argument promotions apply. The depth argument is
emitted at the type of `unsigned int`. Two cases end up with a width
other than 32 bits:
- Targets whose `int` is 16 bits, such as MSP430 and AVR.
Plain `__builtin_prefetch(p, 1, 3)` or `__builtin_frame_address(0)` is
hit this.
- An argument written with a type wider than 32 bits, on any target.
`__builtin_prefetch(p, 1L, 3L)` reproduces this on LP64 targets
`__builtin_prefetch(p, 0 * sizeof(int))` is the same on LP64
#202061
`__builtin_prefetch(p, 1LL, 3LL)` reproduces this on 32 bit targets
Either way the emitted call does not match the intrinsic's signature.
With assertions enabled this trips
`assert(... "Calling a function with a bad signature!")` in
`CallInst::init`;
without them the verifier rejects the module:
```console
$ clang -cc1 -triple msp430 -emit-llvm t.c -o -
call void @llvm.prefetch.p0(ptr %0, i16 1, i16 3, i32 1)
%0 = call ptr @llvm.frameaddress.p0(i16 0)
fatal error: error in backend: Broken module found, compilation aborted!
```
Zero-extend or truncate them to i32 before building the intrinsic call.
The conversion is a no-op where the widths already match, and folds back
to a constant, since Sema already requires these arguments to be
constants in range.
This also removes the FIXME that pointed at the mismatch.
AI assistance helped me find the problem and work out the fix, but I
wrote the code myself.

Currently the default on Apple platforms is "std_thread", which is a

To enable automatic benchmarking of PSTL, set the backend to
"libdispatch" by default, so it doesn't require specific overrides in
`libcxx/utils/ci/lnt/cmake`.
As a drive-by, fixes some of the minor issues with this backend that
surfaced once more pipelines started using it.

[SandboxVec][LoadStoreVec] Vectorize load seed chains (#215944)
LoadStoreVec previously only vectorized store bundles. SeedCollection
already emits homogeneous store and load slices separately, so
runOnRegion() now dispatches on the seed kind and calls
vectorizeStores()
or vectorizeLoads() accordingly.
Add vectorizeLoads() to combine consecutive load chains into a single
vector load, unpack for remaining uses, and clean up dead scalar loads
and pointer operands.
Add load_store_vec_load_seeds.ll covering load-only seeds (no uses,
single use, general uses, vector-typed loads, and mixed-type cases), and
extend load_store_vec.ll with a trivial load-then-store case.

[lldb-dap][test] Only check compile units from stack frames for main.c (#223450)
The `test_stack_frame_compile_unit_id` test case added in #222512 checks
that compileUnitId in a stack frame points to the source file. However,
it does so by checking there is only one unique compileUnitId in the
whole stack trace. This may not be true if start.S is included as a
compile unit.
Relax the check by only looking for stack frames that point to main.c.
Also check the other way, i.e. ensure the same compile unit id isn't
referenced by a stack frame that doesn't point to main.c. This way the
test retains its stated goal of making sure the compile unit id resolves
to its source file while also allowing start.S from a different compile
unit to be present.

[flang][FIRToMemRef] Treat heap-pointer allocas as static, not as dynamic arrays (#223821)
Whole-array assignment of an allocatable inside !$acc kernels with
-Mstack_arrays aborted on !fir.ref<!fir.heap<!fir.array<?xf32>>>. A
fir.alloca !fir.heap<array> is a local heap pointer, but it was
unwrapped and handled as a dynamic array. The memref converter then
peeled only the outer ref and asserted because !fir.heap is not a memref
element.
Keep the pointer as a static allocation. Make convertibleMemrefType use
the same one-pointer peel as convertMemrefType so a nested pointer is
not treated as an f32 array.

[LLVMAABI][AARCH64] Handle homogeneous aggregate return types (#218799)
This change implements the IsHomogenousAggregate() function, which is
shared across targets, and uses it to implement direct passthrough of
return values that meet the homogeneous aggregate criteria.
I'm also adding a new AArch64ABIOptions object that will be used to
track various conditions that are derived from target settings and must
be accounted for in the ABI handling. This change adds only two options,
IsILP32 and IsMicrosoftCXXABI. Other options are expected and will be
added as they are needed.
This change also revises the not-yet-implemented cases, having them
return Ignore rather than Direct so that they fail in more obvious ways.
This was necessary in order to be able to distinguish a return type that
was classified as Direct because it was a homogeneous aggregate from one
that was classified as Direct because it was an unhandled type.

clang: Do not overwrite a module's DataLayout in the backend (#224012)
emitAssembly() unconditionally reset the module's DataLayout from
TargetMachine::createDataLayout(). The TargetMachine's DataLayout is
unreliable given the existence of the "target-abi" module flag, so it
should not be used.
For -x ir input modules this would discard the correct datalayout in
favor of a possibly wrong one.
The post-codegen consistency check compared the module's DataLayout
against clang's frontend getDataLayoutString(), which likewise ignores the
target-abi flag. Recompute the expected layout from the module's own ABI via
Triple::computeDataLayout(getTargetABIName(M)) so the check stays
meaningful without assuming the DataLayout is a fixed property of the target
options. This still detects frontend/LLVM DataLayout drift for generated modules.
PR44896.ll and asan-unified-lto.ll declared x86_64 modules but ran without an
explicit triple, relying on the old overwrite to convert them to the default target.
Pin them to their declared triple and refresh their stale DataLayout strings.

[Clang] Fix `-Wsign-compare` assertion when negating a vector of unsigned integers (#223295)
Fixes #203575
`-1 == -*c`, where `c` points to a vector of `unsigned`, hit the
`unsigned range includes negative?` assertion in `AnalyzeComparison`.
The range analysis for unary `-` and `~` (added in #126846) checks
whether the result type is unsigned with `isUnsignedIntegerType()`,
which never looks through vector types. So the negated unsigned vector
was treated as a signed negation and came back with a possibly-negative
range, even though the operand's own range was correctly unsigned. Same
story for `~*c`.
The check now uses `hasUnsignedIntegerRepresentation()`, which looks
through vector and matrix element types the same way
`IntRange::forValueOfType` and the caller in `AnalyzeComparison` already
do. The binary-operator result gets the same predicate for its
non-negative fixup, since it had the identical blind spot. With that, a
negated unsigned vector takes the same path as a negated `unsigned`

[RelLookupTableConverter] Allow multiple uses of loaded value (#223853)
RelLookupTableConverter previously required `!Load ||
!Load->hasOneUse()`, which prevented converting lookup tables if the
loaded pointer was used more than once in the function.
This restriction is unnecessary since the loaded value itself can be
used many times. The check was likely an over-zealous carryover from
`GV->hasOneUse()` and `GEP->hasOneUse()`.
Remove the check and add a test verifying that lookup tables with
multiple uses of the loaded pointer are converted.

offload components, but it does not hurt to make the code buildable with

[flang][openacc][cuda] Recover acc routine bind info in CUDA Fortran module reads (#223595)
CUDA Fortran device code can call a procedure whose device-side symbol
is given by `acc routine bind(...)` in the module that declares it.
The using translation unit is often compiled with CUDA Fortran enabled
and without an OpenACC target, so the `$acc` sentinel was never
recognized when re-parsing the module file and the bind clause was
dropped.
Enable OpenACC while reading module files under CUDA Fortran as well,
and resolve the recovered directives onto the imported symbols. User
`$acc` in the main source remains ignored without `-fopenacc`; only
directives that already survived into the `.mod` are honored.
A bind(C) host name and an acc bind device name on the same procedure
is the dual-name rule in OpenACC §2.15.1.

[lldb] Add an option to build liblldb statically (#223210)
This builds on the Emscripten host and platform work from the previous
patches.
`liblldb` is currently always created as a shared library. That makes
sense for the normal LLDB installation, but it is restrictive for
embedders where dynamic libraries are unavailable, expensive to load or
simply not the preferred deployment model.
My immediate use case is bringing LLDB into
[WasmBolt](https://github.com/anutosh491/WasmBolt) (try
[here](https://anutosh21.github.io/WasmBolt/)). Loading the complete
`liblldb` WebAssembly side module dynamically has significant startup
overhead. A static build lets the browser application link the required
LLDB components and plugins into its main module during CI, after which
startup is much faster and the linker can remove unreachable code.
The use case is not specific to Emscripten, so this patch adds the
platform-independent `LLDB_BUILD_STATIC_LIBLLDB` option while preserving
the existing shared-library default.
The patch:
- builds `liblldb` as a static library when explicitly requested;
- installs the resulting archive;
- skips shared-library version and export-list processing;
- propagates `LLDB_STATIC` so Windows consumers do not use `dllimport`;
- rejects the incompatible combination with `LLDB_BUILD_FRAMEWORK`.
In my Emscripten 6 experiment, the statically linked final module is
around 74 MB, while the shared `liblldb` side module alone was around 98
MB and considerably more expensive to load.
Tested by:
- building and installing `liblldb.a` natively on macOS;
- building `liblldb.a` with Emscripten 6;
- linking the complete Emscripten `lldb.wasm` executable against the
static target;
- confirming that the default configuration still generates shared
`liblldb`.

[flang][cuda] Limit mem:managed generic matching to allocatable and pointer (#223801)
managed memory mode only puts allocatable and pointer allocations in

they must not match a device/managed/unified dummy during generic
resolution.
Keep the -gpu=mem:unified relaxation for all host variables, which are
device-accessible in that mode.
This stops host calls such as sum(host_array(:)) from resolving to a
CUDA Fortran device-dummy specific.

[llvm][AArch64] Fix FPDiff founding direction in non-sibcall tail calls (#223545)
This fixes another subtle bug in frame accounting (see: #217156 /
#220406), for tail calls that have a non-multiple of 16 bytes worth of
stack arg area, and need that stack arg re-use to be increased to cover
the alignment requirement. This is best illustrated with callers
containing 8 formal arguments covering the first 8 GPRs (x0-x7),
followed by 9 bytes of argument passed on the stack.
In a callee-pops tail call (e.g. tailcc/swifttailcc), the set of
reusable stack arg area bytes has already been sufficiently aligned by
LowerFormalArguments, so growing NumBytes up to StackAlign is enough to
consume that excess. Otherwise (e.g. a plain C-convention call, forced
off the sibcall path, as in the aarch64_inout_za tests), we can't rely
on either having been pre-aligned, so we round NumBytes up to the same
residue mod StackAlign as NumReusableBytes, which cancels the residue
out of their difference (FPDiff), thus keeping the stack aligned going
into the callee.
Concretely, #220406 computed the Realign distance needed to round FPDiff
up to the next multiple of StackAlign, then subtracted that from FPDiff.
Subtracting that round-up distance overshoots rounding down to the
nearest multiple, and in general arrives at a value that may not even be
a multiple of StackAlign. For example, in @caller_last_stack_arg_i64 we
had NumReusableBytes=8 and NumBytes=1 for an FPDiff of 7, which computed
Realign=9, FPDiff=-2, NumBytes=10 instead of the intended NumBytes=8,
FPDiff=0.

[lit] Add --rerun-failed-serially <REGEX> mechanism (#223504)
CI systems sometimes run on hardware or operating system versions that
have known problems that need to be worked around. This change in
particular is motivated by an issue with certain versions of macOS that
very rarely (but often enough to be a problem at CI scale) drop a burst
of parallel debugserver's attach requests. The goal is to recognize this
very situation and the re-run the affected tests without opnening the
door for the entire testsuite to become less reliable due to the retry
mechanism.
Tests that pass the second time are reported as FLAKYPASS, which keeps
them out of the failure count and the exit status.
--max-retries-per-test composes with this: the rerun honors
allowed_retries as well, so each of its attempts is retried in place as
before.
The regex argument restricts the rerun to failures whose output matches
a regular expression. Without it, any flaky test that happens to pass on
the rerun is laundered into a pass; with it, only the failures a known
platform bug produces get a second chance.

Add pwd::DynamicBuffer and overloads of FlatFileDatabase::getnext and
lookup that read into a growable buffer rather than a fixed span.
parse_line now returns ErrorOr<void> and accepts the buffer and line
length so parsers can report ERANGE or EINVAL directly.
Fixed-buffer getnext keeps its signature and never allocates.
Fixed-buffer lookup skips unrelated oversized preceding records using a
temporary ScopedDynamicBuffer and reports ERANGE only when the matched
record does not fit in the caller's buffer.
DynamicBuffer is trivially destructible by design so that it can be a
constant-initialised process global. Storage is released explicitly by
whoever owns it.

[LLDB] Skip test under gold (#224113)
The way gold emits symbols created by linker scripts is not implemented
in LLDB.
For the record, I asked Claude to write a patch to implement the
functionality but it came up with a linear search through all sections
which I was afraid might be quite expensive. I'm happy to purse that as
an alternative if people think it is worth it, with the caveat that I am
not an ELF expert.

[CopyProf] Implement minimal CopyProf runtime. (#223458)
The runtime tracks object copies using shadow memory (with a 1:8
compression scale).
Each thread uses TLS to keep track of whether execution is currently
inside a special member function. Copy functions mark corresponding
shadow memory as a copy. Upon destruction, if an object was marked as a
copy and never modified, it is classified as an unnecessary copy, and a
report with a stack trace is generated.

[WebAssembly] Use Single as the default Triple thread model (#223917)
Clang defaults WebAssembly to a single-threaded model unless atomics and
bulk-memory are enabled, whereas Triple::getDefaultThreadModel()
previously defaulted to POSIX for all targets. Because Clang only emits
the "thread-model" module flag when the active thread model differs from
the triple's default, single-threaded Wasm objects recorded
"thread-model"="single" while multithreaded objects omitted the flag.
When linking mixed objects in LTO, the merged module inherited "single",
causing passes like LICM and AtomicExpand to treat multithreaded
programs as single-threaded.
Change Triple::getDefaultThreadModel() to return ThreadModel::Single for
WebAssembly so that multithreaded objects explicitly record
"thread-model"= "posix" and single-threaded objects omit the flag.
Additionally, update WebAssemblyCoalesceFeaturesAndStripAtomics to set
the module thread model to POSIX when threading features are enabled and
no explicit module flag is present, ensuring backend passes like
AtomicExpandPass preserve atomics in raw IR modules compiled via llc.

[CAS] Read a CAS file's reserved size from st_blocks, not st_blksize (#224104)
FileSizeInfo reports how much disk a file already has, which
MappedFileRegionArena records so it knows how far ahead it has reserved.
However the file size was accidentally computed from st_blksize which is
the preferred I/O size, not the number of allocated blocks for the file.
The value is read when a database is created or reopened, so a reopened
database believed almost none of its disk was reserved and reserved it
again from near zero, a megabyte per allocation. Fix the problem by
using the correct size.

workflow. This patch fixes that by ensuring the projects executed for
.ci/workflow changes are derived from everything else which means we do
not need to manually maintain the list and risk leaving it out of date.

`union { unsigned Words[3]; void *Ptr; }` is 16 bytes because the
pointer's alignment rounds it up, and no member covers that size. The
pass refused to classify unions like that at all, so anything holding
one failed to compile. Tail padding doesn't change how an eightbyte
classifies, so this drops the precondition and classifies the union from
its own size.

[bazel][libc] Be explicit about pic/nopic in startup_rules.bzl (#223851)
Currently, `_get_object_files` gets object files from
`OuputGroupInfo.compilation_outputs`, which isn't very well documented
any will often just choose the PIC variant: see
[`cc_helper.bzl`](https://github.com/bazelbuild/rules_cc/blob/661b75de668c3b673f5550e0340e134ccf923956/cc/common/cc_helper.bzl#L192)

This PR updates `merge_relocatable_object` to propagate both pic/nopic
variants of the merged object, and updates `libc_startup_object` to be
explicit about its choice of pic/nopic.
The exact choice of how to handle pic/nopic may need to be updated in
the future as we add `rcrt1.o`, but the setup in this PR is better than
just using `compilation_outputs` verbatim.

[ORC] Add ConnectionSpec for connection string parsing (#224000)
A ConnectionSpec is the parsed form of a string describing one
connection a process should establish with its peer:
<transport>[:<action>]=<descriptor>
E.g. "fd=3" or "tcp:connect=localhost:20000". The parser only checks
punctuation: transport and action names are opaque tokens, and the
descriptor's syntax is left to the transport, which lets a descriptor
contain ':' and '=' unescaped (e.g. "tcp:listen=[::1]:0").
This will be used by llvm-jitlink and llvm-jitlink-executor to
generalize out-of-process executor connection setup beyond the current
fd/TCP-only options.

[SLP] More accurately cost RISCV scalar splats (#213104)
Backends may have a fast path for splatting scalar operands (i.e. rather
than generating the splat vector, the vector instruction may be able to
take a scalar operand), for example RISCV `vfoo.vx` instructions. Pass a
hint to the TTI when costing the insert/shuffle sequence in such cases.
Fixes #212413.

[WinEH] Only emit the async-EH nop after EH_LABEL on x86 (#219275)
Under `-fasync-exceptions`, `AsmPrinter::emitFunctionBody()` emits a nop
after an `EH_LABEL` whose next instruction can fault, so that the
faulting instruction opening an EH region does not share an address with
the return address of the call before it.
`EH_LABEL` is a meta-instruction and reports a size of zero, so that nop
is invisible to `getInstSizeInBytes()` and to everything that sums it.
On AArch64 that undercounts block offsets, `AArch64CompressJumpTables`
picks a one-byte jump table entry that does not fit, and the assembler
rejects it with `value evaluated as 258 is out of range`. That is how
this was found, building OpenCV's bundled protobuf for
`aarch64-pc-windows-msvc` with clang-cl `/EHa`. `BranchRelaxation` sums
the same sizes and has the same hole.
Only x86 needs the padding. On Arm64 the unwinder already backs the PC
up over a call when it knows there was one, which is exactly the case
the nop protects against, So gate the nop on x86 triples. That also
stops emitting it on armv7-windows, same size mismatch on #221687.
That in turn lets the `EH_LABEL` exception added to
`TargetInstrInfo::getInstSizeVerifyMode()` in #223641 go. x86 still
emits the nop, but x86 does not implement `getInstSizeInBytes()`, so
the base class returns `~0U` and the `AllowOverEstimate` comparison is
vacuous there. Every target that does implement it has stopped emitting
the nop.

[SeparateConstOffsetFromGEP] Rebuild GEP indices at their definition point (#223546)
When a constant offset is split out of a GEP index, the rebuilt index
replaces the original one. Rebuilding the index immediately before the
GEP amounts to sinking the index computation, increasing live ranges and
register pressure. This change attempts to rebuild the index at the
definition point of the original index instead. The same insertion point
is used for the `idxprom` cast created by
`canonicalizeArrayIndicesToIndexSize` too.

[bazel][libc][test] Allow LLVM-libc tests to be run in full-build mode (#219262)
This PR makes the required changes to run LLVM-libc full build tests in
Bazel. After this PR, most tests pass:
```
bazel test @llvm-project//libc/test/... --config=ci -- at llvm-project//libc:build_mode=full --keep_going
Executed 760 out of 970 tests: 760 tests pass and 210 fail to build.
```
Follow on changes will fix specific tests that are failing (some missing
deps etc).
Specifically, this PR:
- Propagates the correct dependencies and compiler/linker options from
[`add_libc_hermetic`](https://github.com/llvm/llvm-project/blob/4098f568c46e06b6df470111868b4c165dd80f4d/libc/cmake/modules/LLVMLibCTestRules.cmake#L750).
- Adds `crt1.o` and hermetic utils as deps for all full-built tests.
- Fixes some build deps to be full-build compatible.

[NFC][AMDGPU] Separate VOPD candidate selection (#223518)
This PR separates VOPD candidate matching from selection without
changing generated code.
`GCNCreateVOPD` used to choose a pair as soon as `tryMatchVOPDPair`
found one. That made matching and selection one operation: the first
match consumed both instructions before later work could decide whether
the pair was usable.
We now record matches in program order, collect every adjacent
candidate, and select the same greedy non-overlapping set in a separate
step.
This gives later changes a place to reject or rank a candidate without
hiding an overlapping pair that uses its second instruction.

[Attributor] Only seed live internal callees during deduction (#222226)
When a basic block becomes live, assumeLive marks its internal callees
live to seed attributes for deduction. Currently, this also happens when
a liveness AA is initialized during MANIFEST or CLEANUP, after the
fixed-point iteration has finished.
In CGSCC runs, cleanup can query the liveness of a shared caller for
each callee SCC. Seeding all internal callees in that caller's live blocks
can then cause quadratic initialization work.
Restrict this bulk seeding to SEEDING and UPDATE. Continue recording
live blocks and allow on-demand attribute queries in the later stages.

his code
```cpp

a Private module fragment here is illegal because it can only be
declared in a primary module interface unit, instead of raising an error
clang crashed because of this assertion
```cpp
assert((!getLangOpts().CPlusPlusModules ||
SeenGMF == (bool)this->TheGlobalModuleFragment) &&

```
the mismatch happened because `ParseModuleDecl` assigned ImporState
wether or not it was semantically correct:
```cpp
ImportState = ImportState == Sema::ModuleImportState::ImportAllowed
? Sema::ModuleImportState::PrivateFragmentImportAllowed
: Sema::ModuleImportState::PrivateFragmentImportFinished;
return Actions.ActOnPrivateModuleFragmentDecl(ModuleLoc, PrivateLoc);
}
```
Also `ActOnPrivateModuleFragmentDecl` was returning `nullptr` in both
failure and success cases.
So i made it return a non-null object and only assign the ImportState on
sema failure.

[flang-rt] Copy out only the modified suffix of an argument temporary (#222101)
`CopyOutAssign` currently copies the whole temporary back over the
original unconditionally. When the effective argument is not definable —
a named constant, for example — and the callee, conformingly, never
modified it, that copy-back stores unmodified bytes into storage that
may be read-only. With this change, `CopyOutAssign` scans the temporary
for the first element whose bit pattern differs from the original and
copies back only from that element through the end, in one fused pass:
an unmodified copy-out performs no stores at all, so compiler-generated
copy-out can never be the reason a conforming program writes into
read-only storage. The comparison is bitwise, which is exact here
because the temporary was created as a bitwise copy by `CopyInAssign`:
unmodified elements compare equal even for NaNs and padding bytes, which
a value comparison would misjudge.
The change is performance-neutral in practice (measurements summarized
in a comment below): copy-out's destination is essentially always
discontiguous — the temporary exists only because the actual argument
failed a runtime contiguity check — and on that shape the scan-then-copy
is within a few tens of percent of the unconditional copy in either
direction on microbenchmarks, and indistinguishable at whole-application
level.
The system environment variable `FLANG_RT_COPYOUT_MODIFIED_ONLY=0`
restores the previous unconditional copy-out, as an escape hatch and for
A/B comparison; it is documented in `flang/docs/RuntimeEnvironment.md`.
Note it restores stores of unmodified data (including into read-only
storage), so it is not a "safer" mode.

[IR] Avoid collecting COMDATs for non-module printing (#221460)
`AssemblyWriter` scans every global object in its constructor to collect
referenced COMDATs. That collection is only used when printing a
complete module, but the constructor also runs for standalone value and
instruction printing.
Move COMDAT emission into `printModule()`. Print each group at its first
global-object use and keep only a local set to avoid duplicate
declarations.
On `bench/sqlite/original/shell.ll` from `llvm-opt-benchmark`, the
median `opt -passes=dot-cfg` time dropped from 1.65 s to 0.40 s, about
4.1x faster. All 687 generated DOT files matched after normalizing
process-specific node IDs.

[MLIR][Affine] Refactor dependence testing to work on relations, not just on operations (#223188)
This change is effectively NFC for all users of affine dependence
analysis in the tree or outside. It performs a minor refactoring of the
API to allow more general usage.
`checkMemrefAccessDependence` takes two `MemRefAccess`es, each wrapping
an operation, so it can only be asked about accesses that already exist.
A transformation deciding whether to make a change has the opposite
question: whether the accesses it is about to create would depend on
each other. Loop fusion is one -- whether the stores of a slice would
still be one-to-one in the loops it is about to be placed under settles
whether their parallelism survives it, and it has to know before it
fuses.
Nothing in the dependence analysis needs the operations. Everything from
the point where the two access relations are in hand -- inverting one,
composing, adding the ordering constraints, testing the result for
emptiness -- is already relation-only. Split that out as
`checkAccessDependence`, taking the relations and the loop depth, and
leave `checkMemrefAccessDependence` as the operation-based entry point:
it keeps what genuinely reads the IR, the memref and write-op checks,
the affine scope and common block ones, and the
source-precedes-destination one that a depth past the shared loops calls
for.
Split `MemRefAccess::getAccessRelation` the same way. The relation is
built out of an access map and an iteration domain, and only the two of
them being read off an operation ties it to one, so `getAccessRelation`
takes them directly and the method reads them off and calls it.

[AMDGPU] Form VOPD3 pairs with pair-local literal moves (#223431)
VOPD3 cannot encode literal operands, but its src0 can read scalar
registers. In this PR, we try to allow to form a pair with one distinct
non-inline constant value by moving that value to a free SGPR. If both
components use the same value, one move serves both, but we reject pairs
that need two different values, since that doesn't buy us anything.
Ffunctions without tracked liveness, and functions optimized for size
are also rejected.
With this change, `GCNCreateVOPD` checks every adjacent pair before it
selects a greedy non-overlapping pair. This lets an infeasible pair fall
through to the overlapping next one. We use one reverse liveness walk to
find an SGPR that is free over each pair-local range. Disjoint selected
pairs can reuse the same SGPR. Each accepted pair adds at most one
`S_MOV_B32` for the one instruction removed by fusion.
The post-RA scheduler uses the same matcher policy, so it will not
cluster a two-value pair that the create pass cannot build.

I probably burned hundreds of millions of tokens to get to this point,
which I think is fairly clean now.

[lldb] Stop caching cross-module callees in CallEdge (#224165)
DirectCallEdge cached the Function it resolved for its callee. A
CallEdge is owned by a Module in the shared module cache, so it
outlives any one Target, while the callee it resolves to depends on
that Target's image list and dies with its own module. The cached
pointer dangled once the callee's module was unloaded, crashing the
next backtrace that walked tail call frames.
Keep only the symbol name and re-resolve on every call. GetCallee
returns a SymbolContext so the caller holds the callee's module for as
long as it uses the Function.
Scoping the lookup to the caller's own module or compile unit would
also make the cache safe, but direct tail call edges cross module
boundaries by design. Clang points DW_AT_call_origin at a declaration
DIE when the callee is external. See the cross_dso tail call test.

[RISCV] Do not re-validate target ABI in AsmParser if already resolved by streamer (#223606)
Commit 105ff16f816f (https://github.com/llvm/llvm-project/pull/213410)
changed RISCVABI::computeTargetABI() to return Expected<ABI> and added
validation to RISCVAsmParser::onBeginOfFile() to report invalid
-target-abi flags with real source location in llvm-mc.
However, this broke LTO builds containing inline assembly (e.g. Android
riscv64 builds and downstream Rust in
https://github.com/rust-lang/rust/pull/162783). During LTO, LLD sets
TargetOptions.MCOptions.ABIName from the module's target-abi metadata
("lp64d"), while the linker's default TargetMachine subtarget lacks
"+d" (individual functions specify "+d" in target-features).
RISCVSubtarget handles this gracefully by emitting a diagnostic note
and falling back to lp64 for code generation. When inline assembly was
subsequently parsed, AsmPrinter::emitInlineAsm instantiated
RISCVAsmParser with a subtarget lacking "+d", causing onBeginOfFile() to
re-validate TargetOptions.ABIName and fail with a fatal error.
To fix this, skip the parser validation whenever the streamer has
already resolved an ABI. This preserves llvm-mc diagnostics on invalid
command-line flags while avoiding conflicting validation when assembling
inline asm during code generation.

[clang][clangd] Resolve decltype when printing types for display (#223950)
`decltype(x)` is rarely what a reader wants to see in a display context:
a code completion offering `set_x(decltype(x) val)` conveys much less
than `set_x(int val)`.
clangd already worked around this for hover, by stripping decltypes off
the type before printing it, with a FIXME noting that this belongs in a
printing policy and that it does not handle composite types.
`HoverTests.cpp` carries a matching FIXME on one of the cases it misses.
Add such a policy flag, honour it in `TypePrinter`, and set it both for
code completion and for the types clangd displays on hover.
Applying it in the printer rather than at the call site also covers the
cases the workaround could not reach:
```c++
const decltype(a) b; // was `int`, now `const int`
void f(decltype(lamb) &bar); // was `decltype(lamb) &`, now `(lambda) &`
auto f(decltype(a)) -> decltype(a); // now `auto (int) -> int`
```
The first of those was a bug: `castAs<DecltypeType>()` looks through
qualifiers, so the workaround silently dropped the `const`.
Since the printed type may now already be desugared, an "aka" suffix
that would repeat it verbatim is suppressed.
A dependent `decltype` has no resolved type to offer and is left as
written. The declaration clangd shows next to the type is printed with a
different policy and still reflects the source spelling, so the
`decltype` remains visible on the hover card. Code completion and
signature help have no such fallback, and there the resolved type
replaces the spelling outright.

[compiler-rt][ARM] Make ARMv4T assembly builtins interwork (#221725)
ARMv4T can't switch instruction state when a saved return address is
loaded directly into the pc. Several builtins did exactly that, so a
call from Thumb could call into Arm state and return without switching.
To mitigate that, this patch amends POP_PC and adds
POP_PC_WITH_REGS, which expand to sensible code depending on
what arch they are compiled for. ARMv5 and later keep direct pop-to-pc
forms. v4T returns through ip and bx.

[SROA] Avoid unnecessary stack realignment when rewriting allocas (#222967)
SROA can introduce dynamic stack realignment when rewriting an aggregate
alloca as a vector. On SystemZ (`S64`), a five-pointer structure with
alignment 8 becomes `<5 x ptr>` with alignment 64, adding an alignment
mask and extra stack-frame setup instructions.
Create replacement allocas with the alignment inherited from the
original alloca and partition offset, then use `tryEnforceAlignment` to
request the preferred type alignment. This reuses the existing
stack-alignment check: when a natural stack alignment is specified,
promotions beyond it are rejected. Stronger inherited alignments are
preserved.
Add SROA-only regression coverage for `S64`, `S128`, unspecified natural
stack alignment, and explicit stronger alignments. Existing SROA,
debug-info, and NVPTX tests retain their original RUN lines and checks,
including the NVPTX vector stores.

[libc] Make it possible to join the main thread (#221177)
Joining the main thread currently crashes because its ThreadAttributes
has a null platform_data pointer, causing Thread::wait() to dereference
a null futex.
While this is not a frequently used feature, it is supported by other
implementations, and I believe it is required by POSIX (the exec page
says that the main thread is created in a joinable state, and neither
pthread_join nor pthread_exit mention them not working on the main
thread).
This patch sets up the main thread attributes during startup:
- allocate a static futex for the main thread's clear_tid and point
platform_data to it
- invoke set_tid_address to have the kernel clear the futex and wake
waiters on thread termination
- mark the main thread as joinable (it was previously defaulting to
detached)
The test for this functionality exposed the bug where the thread return
value is not preserved (and therefore not passed to pthread_join) for
threads exiting via pthread_exit, so I fix that as well.
This patch required accessing the CLEAR_TID_VALUE constant from multiple
files, but I couldn't find a suitable header to place it in. Instead of
creating a new one, I just delete the constant, as we don't really care
about its value -- only that it is not zero.

[SCEV] Look thru more expressions in isKnownMultipleOf (#219951)
Generalize the existing logic to look through AddRecs to look through
Add, Mul, and MinMax expressions in isKnownMultipleOf, noting that this
simply increases precision of added predicates, allowing us to add more
fine-grained predicates. It also fixes an underlying bug in the case the
AddRec wraps. The patch has no optimization impact at the moment, and
only serves to have higher precision in its sole user,
DependenceAnalysis.

Move Mangler functions into Mangler.h so that they can be used from

This is a temporary fix to enable use of SymbolNameSpec in
OrcTargetProcess (see https://github.com/llvm/llvm-project/pull/224188).
Future work will reorganize these libraries and should allow this code
to sink back down into a .cpp file.

[NVPTX] Add support for f32x2 mixed-precision add/sub (#221957)
This change adds support for mixed precision addition and
subtraction of `f16x2` and `bf16x2` with `f32x2`, where the
following upconverting patterns:
```
%e = fpext <2 x half> %h to <2 x float>
%res = fp-operation(%e, ...)
...
%e = fpext <2 x bfloat> %b to <2 x float>
%res = fp-operation(%e, ...)
where the fp-operation can be any of:
- fadd
- fsub
- llvm.nvvm.fadd.v2f32
```
are lowered to `add/sub.{rnd}.f32x2.{f16x2/bf16x2}.f32x2`, and the
following downconverting pattern:
```
%sum = llvm.nvvm.fadd{.ftz}.v2f32(%a, %b, rz)
%lo = extractelement <2 x float> %sum, i32 0
%hi = extractelement <2 x float> %sum, i32 1
%res = llvm.nvvm.ff2{f16x2/bf16x2}.rz(%hi, %lo, false)
```
is lowered to `add/sub.rz{.ftz}.{f16x2/bf16x2}.f32x2.f32x2`. These
instructions combine the conversion and the addition into one
instruction from `sm_107f` onwards. `fneg` followed by one of the
above addition patterns is lowered to the corresponding `sub`
instruction.
The upconverting patterns are folded only when atleast one of the
`fpext`
operands have a single use, thus purely eliminating the conversion.
The downconverting patterns are folded only when the `f32x2` result
is used solely by the conversion, avoiding generating an unnecessary
additional `add/sub` instruction.
The tests have been verified through ptxas-13.4.

may no longer hold afterwards, turning a defined result into poison:

[AMDGPU] Use s_fmamk_f32 when the folded addend is inlinable (#218955)
When folding a constant into src2 of s_fmac_f32, the AK form
(s_fmaak_f32) was always selected, which puts the folded addend in the
literal slot. If that addend is an inline constant while one of the
multiplicands is not, this wastes the literal slot and still requires an
extra s_mov_b32 for the multiplicand.
Choose the instruction variant based on which operand actually needs the
literal instead. If the folded addend is inlinable and a multiplicand is
not, use the MK form (s_fmamk_f32), placing the non-inlinable
multiplicand in the literal slot and encoding the addend inline.

mangle-and-intern it internally; executor-side registrations and the
remaining intern sites mangle the name too, so both sides still agree on
the symbol.
All names are Verbatim, so this is name-neutral (mangling is a no-op);
flipping any of them to a mangled kind (e.g. C) is a follow-up.

-----------
[clang] Look through alias templates when visiting dependent base classes (#223713)
When gathering the visible declarations of a class for code completion,
a dependent base class is resolved by taking its
`TemplateSpecializationType` and casting the template it names to a
`ClassTemplateDecl`. If the base is named through an alias template,
that cast fails, because the `TemplateName` refers to a
`TypeAliasTemplateDecl`. The base is then skipped, along with everything
it declares.
libstdc++'s `std::allocator` runs into this: it derives from
`__allocator_base<T>`, which is an alias template for
`__new_allocator<T>`. Before C++20, `allocate()` and `deallocate()` are
declared only in that base (the declarations in `allocator` itself are
guarded by `__cpp_constexpr_dynamic_alloc`), so a dependent
`std::allocator<T>` offered no members at all beyond the implicitly
declared ones:
```c++
#include <memory>
template <class T> void f(std::allocator<T> a) {
a. // nothing useful was offered here
}
```
Look through the alias to the class template it ultimately names.

[clang][bytecode] Give a discarded composite prvalue a result object (#219952)
A default member initializer can refer to previously initialized
subobjects, so `this` has to denote something while it is evaluated. A
discarded composite prvalue had no result object, so the interpreter
rejected code the legacy evaluator accepts:
```cpp
struct A { int &x; constexpr ~A() { x = 0; } };
struct B { int &x; const A &a = A{x}; };
constexpr int f() { int x = 1; B{x}; return x; }
constexpr int r = f(); // error: implicit use of 'this' pointer
static_assert(r == 0); // FXIME: 'r' shouble be 0, it's a bug in clang, see https://github.com/llvm/llvm-project/issues/85601.
```
https://godbolt.org/z/rb993Ef9d
This patch materialize a result object for a discarded composite prvalue
and initialize into it. A discarded list of primitive type keeps
discarding its initializers, as there is no object to establish there.
Also let an explicit initializer nested in a default member initializer
see the surrounding initializer's `this` reconstruction.

Add a float-specific fputil::round overload for roundf. It uses
FPBits<float> and the biased exponent to handle sub-unit values,

For finite fractional values, add the rounding bit and clear the lower

[LLD][ELF] AArch64 Errata patch use STT_NOTYPE for symbols (#223686)
Use STT_NOTYPE instead of STT_SECTION for local symbols created for the
destination of patch return relocations. This avoids corrupting the
-emit-relocs output for existing relocations that target the
OutputSection's STT_SECTION symbol.
At the time the errata patch runs the .symtab section is expected to
contain at most one STT_SECTION symbol per OutputSection. Adding a new
STT_SECTION symbol causes the -emit-relocs output to use the newly
created symbol for the patch return rather than the OutputSection's
STT_SECTION. By using a STT_NOTYPE symbol the errata patch has no effect
on the -emit-relocs output.

Fix llvm bdce debug salvage (#220900)
BDCE simplifies constant-mask `and`, `or`, and `xor` instructions when
the changed bits are not demanded by program uses. It can similarly
replace a `sext` with a `zext` when none of the sign bits are demanded.
Both transformations used ordinary RAUW, which also redirected direct
debug uses to values with different meanings.
Replace only non-metadata uses when applying these optimizations. This
leaves direct debug users for BDCE's existing reverse-order salvage
pass, which reconstructs supported operations in a `DIExpression` and
makes unsupported locations unavailable.
Add regression tests covering salvage of `and`, `or`, and `xor`, the
unavailable fallback for an unrepresentable wide constant, and
preservation of signed-extension semantics when program uses receive a
`zext`.

[Support] Add ToolSession for in-process tool invocation (#221996)
Please read
[RFC](https://discourse.llvm.org/t/rfc-embeddable-llvm-tool-drivers-for-long-lived-hosts/91754)
& [RFC
section](https://discourse.llvm.org/t/rfc-embeddable-llvm-tool-drivers-for-long-lived-hosts/91754#p-367966-why-initllvm-ownership-matters-7)
This patch introduces `LLVMToolSession`, which lets a long-lived host
own LLVM process initialization and invoke registered LLVM tools without
constructing and destroying `InitLLVM` for every call.
The existing `llvm` multicall driver is used as the first consumer. It
already combines several callable tool entry points in one executable,
making it a small and concrete place to establish the session model
without changing the individual tools.
An `LLVMToolSession`:
- owns one `InitLLVM` instance for the lifetime of the host;
- owns the registry of callable tools;
- creates a `ToolContext` for each invocation;
- allows a tool to find or invoke another tool through that same
session.
This is intended to support hosts such as
[WasmBolt](https://github.com/anutosh491/WasmBolt) (try
[here](https://anutosh21.github.io/WasmBolt/)), where multiple LLVM
tools run sequentially—and sometimes call one another—inside one
long-lived WebAssembly process.
The patch deliberately does not yet:
- change Clang, LLD, `llc`, or `opt`;
- address process-global `llvm::cl` state;
- remove `InitLLVM` from standalone tool wrappers.
Those should remain separate follow-up changes so each part can be
reviewed independently.
I have added tests for
- a real `llvm-cxxfilt` invocation through `LLVMToolSession`;
- repeated and nested tool invocations within one session;
- unknown-tool handling;
- the existing `llvm-driver` tests, including multicall and symlink
invocation.

[AArch64] Use SVE for load-extend-broadcast (#221689)
On certain cores, it is faster to use SVE ld1r instructions to load,
extend and broadcast an integer value to a vector in all cases other
than 64bit vectors where no type promotion occurs.
To acheive this, introduce a tuning option, `PreferSVEVectors` for use
when combining DUP instructions to create a Splat Vector to the scalable
alternative, and then use the already implemented scheduling model
patterns for splat vectors to end up generate the ld1r instruction.
If used in a loop, the predicate will be hoisted outside of the loop.

[clang][bytecode] Add a function frame allocator (#220229)
Add a function frame allocator we share across evaluations.
For code like
```c++
consteval int foo() {
int a = 0;
for (int i = 0; i != 10; ++i)
inc(a);
return a;
}
```
We previously `new[]`-ed a frame for every call of `inc()`, and
`delete[]`d the memory again directly after, resulting in lots of small
(in this case) allocations.
Add a `FrameAllocator` class that handles frames like a LIFO stack and
allocates memory in 4kb chunks. If a newly created frame fits into an
existing chunk, we don't have to allocate anything and simply
placement-new the `InterpFrame` into the existing chunk. We allocate new
chunks as needed.
We can't e.g. use a `std::vector<char>` for this since addresses into
`InterpFrame` memory must stay stable during a frame lifetime.
When compiling `APFloat.cpp`, the stats print this output:
```console
*** FrameAllocator stats ***
Chunk 0: 176 / 4072 (4.32%)
Max allocated bytes: 13424
Largest frame: 5208
Frames created: 286986
Allocations: 63
Occupancy: 4.32%
```
So for 286986 created frames, we only did 63 allocations. The output was
printed at the end of the compilation so the printed chunks and
occupancy aren't very useful.
For a test case that creates lots of function frames, e.g.
```c++
consteval void inc4(int &a) { ++a; }
consteval void inc3(int &a) { inc4(a); }
consteval void inc2(int &a) { inc3(a); }
consteval void inc(int &a) { inc2(a); }
consteval int foo() {
int a = 0;
for (int i = 0; i != 10; ++i)
inc(a);
return a;
}
static_assert(foo() == 10);
```
we save 2.5%. If all of the functions in the sample above gain a `char
c[1024]` local variable, this patch improves the runtime by 12%.

[RISCV] Account for VL toggle cost when splitting VP memory intrinsics (#223992)
Not an alternative to #222836 since this doesn't handle all cases, but
something we should do anyway in the TTI to be accurate.
For vp.load/vp.gather/vp.strided.load and their store counterparts, when
they're split they introduce extra vl toggles which involve computation
on the evl, e.g.
vsetvli a2, zero, e8, mf4, ta, ma

csrr a2, vlenb
srli a3, a2, 3
vslidedown.vx v0, v0, a3

addi a4, a4, -1

and a3, a4, a3
add a5, a0, a5

bltu a1, a2, .LBB44_2

.LBB44_2:
vmv1r.v v0, v8
vsetvli zero, a1, e64, m8, ta, ma
vle64.v v8, (a0), v0.t
Account for some overhead in the cost to influence the loop vectorizer
to avoid picking VFs that lead to types that need split.

An or reduction of and(shl(x, s), m) lanes that each cover a disjoint
contiguous byte field of the result is a repacking of the per-lane field
contents, not a shift and reduce. Prove the fields disjoint from the
per-lane possibly-set bits (a saturating numeric upper bound combined with
known bits), then emit the pack as a trunc, an optional per-lane lshr, a
byte shuffle and a bitcast. A plain byte reversal becomes a bswap, an
identity byte order needs no shuffle, and byte-zext lanes compact for free.

clang-linker-wrapper: Set the host DataLayout on the offload wrapper module (#224280)
The offload wrapper module was created with only a target triple, and
the datalayout wasn't set until later, where it was copied from the
TargetMachine, after the wrapping code already ran.
The wrapping code did query the datalayout for the pointer size, so this
was broken for host and devices with different pointer sizes. queries the
DataLayout (e.g. the size_t / intptr type via getSizeTTy), so on a
host whose pointer size differs from the default layout (e.g. a 32-bit
host) it used the wrong integer width for image offsets.
This removes a use of TargetMachine::createDataLayout, which I am trying
to remove.

[libc] Add support for SYS_fchmodat2 in fchmodat (#223997)
### Summary
Linux kernel 6.6 introduced the `SYS_fchmodat2` system call, which
accepts a 4th `flags` argument (`int fchmodat2(int dirfd, const char
*pathname, mode_t mode, unsigned int flags)`). This allows flags like
`AT_SYMLINK_NOFOLLOW` and `AT_EMPTY_PATH` to be passed directly to the
kernel.
Following the discussion on #223165, this patch adds support for
`SYS_fchmodat2` in `fchmodat`, while providing fallbacks when
`SYS_fchmodat2` is not supported.
Fixes #223953
Formatted using Gemini.

[lld][MachO] Fix --reproduce paths for non-global symbol lists and SDK libraries/frameworks (#223687)
`--reproduce` currently has two path-rewriting problems:
1. Non-global symbol lists are included in the archive, but their paths
in the response file are not
relativized.
2. SDK roots and library/framework search paths are relativized
independently. Since the driver does not
reroot relative search paths, replay can fail to find libraries or
frameworks inside the SDK.
This patch fixes both by relativizing non-global symbol-list paths and
resolving SDK prefixes before
relativizing library/framework search paths.

[clang] Fix surrogate call through a using-declared conversion function (#221723)
Fixes #189146
A call to a class object that goes through a conversion function to a
function pointer ("surrogate call") asserted when that conversion
function had been brought into the class with a using-declaration, e.g.
`using M::operator auto;`. The surrogate loop in
`BuildCallToObjectOfClassType` unwraps the `UsingShadowDecl` to get the
conversion function but records the shadow as the candidate's
`FoundDecl`, so the two are not the same pointer and the assertion
fires. It wasn't only the assertion, though: the line before it passed
`FoundDecl` to `DiagnoseUseOfDecl`, which skips all of its function
checks on a shadow decl, and surrogates never go through `OR_Deleted`
since they carry no `Function`. So with the assertion relaxed, a deleted
conversion function reached through a using-declaration would have
compiled without complaint.
The surrogate branch now diagnoses use of the conversion function itself
rather than the found declaration, which is what `BuildCXXCastArgument`
already does for the ordinary user-defined conversion path, and the
assertion compares against the underlying declaration. Access checking
keeps using `FoundDecl`, since the using-declaration's access is the one
that matters. For conversion functions declared directly in the class
the two pointers are identical, so nothing changes there.

[flang][OpenACC] Skip non-loop evaluations when descending a collapsed/tiled DO nest (#223579)
## Summary
- The collapse/tile loop-nest descent in `Bridge.cpp` (used for OpenACC
`collapse`/`tile` and CUDA Fortran `!$cuf kernel do`) assumed each loop
level's nested evaluations have the fixed shape `{NonLabelDoStmt,
DoConstruct, EndDoStmt}` and unconditionally advanced to the second
nested evaluation to find the next inner `DO`.
- A compiler directive (e.g. `!DIR$ IVDEP`) placed between loop levels
inserts an extra sibling evaluation there, so the descent landed on the
directive instead of the inner `DoConstruct` and lowered the directive's
(empty) nested evaluations as the loop body — silently dropping the real
body with no diagnostic.
- Adds a helper that searches a level's nested evaluations for the
actual `DoConstruct`, matching the approach already used by
`visitLoopControl` in `OpenACC.cpp`, and uses it at all three affected
descent sites (OpenACC collapse/tile, and the two CUDA Fortran kernel-do
sites).
## Test plan
- New lit test
`flang/test/Lower/OpenACC/acc-loop-collapse-directive-between-loops.f90`
covering `collapse(2)` with `!DIR$ IVDEP` and `collapse(3)` with `!DIR$
NOVECTOR` between loop levels.
- Verified the new test fails without the fix (directive absorbed as
loop body, no `hlfir.assign` for the real body) and passes with it.
- Existing `acc-loop-collapse-force-lowering.f90`,
`acc-loop-collapse-force-non-tightly-nested.f90`,
`do-concurrent-collapse.f90`, `cuda-kernel-loop-directive.cuf`,
`cuda-kernel-do-reduction.cuf` all still pass.

[mlir][vector] Reject a 0-d operand in the outerproduct parser (#219917)
`vector.outerproduct` builds its result type from dimension 0 of its
operands, which a 0-d vector does not have, so `mlir-opt` aborts while
parsing, before the verifier gets a chance to report anything:
```mlir
%0 = vector.outerproduct %a, %b : vector<f32>, vector<4xf32>
```
The parser now emits the same diagnostic the verifier already gives for
that operand, `expected 1-d vector for operand #1`. Only rank 0 is
caught here, rank 2 and above still reach the verifier unchanged.
This PR started out touching three parsers and was narrowed to
`outerproduct` at review request. The `transfer_read`/`transfer_write`
and `contract` parsers follow as separate PRs.

[clang][Parse] Fix stale `CurParsedObjCImpl` after an `@implementation` ends early (#219953)
Fixes #209503
`ObjCImplParsingDataRAII` only reset `CurParsedObjCImpl` in its
destructor, but an `@implementation` can be finished well before that:
`CheckNestedObjCContexts` ends it as soon as a nested
`@interface`/`@protocol`/`@implementation` shows up, and that container
is then parsed inside the same frame. Anything defined in there still
looked like it was inside the already finished `@implementation`, so
`ParseFunctionDefinition` queued the body into a `LateParsedObjCMethods`
that nobody was going to drain again, and the destructor's
`assert(LateParsedObjCMethods.empty())` fired. The fatal `#include` in
the report is a red herring, by the way — it only hides the diagnostics
for the function that gets queued.
`finish()` now restores the previous `CurParsedObjCImpl` the moment the
`@implementation` ends, instead of the destructor nulling it later.
Restoring rather than clearing also covers the mirror image: an
`@implementation` nested through a namespace inside another one used to
wipe out the outer, still open one when it ended, and the next method
definition in the outer one tripped the `Method out of @implementation`
assert. The new test has both shapes.

[lldb] Substitute breakpoint opcodes in expedited memory (#224304)
A stub may send expedited memory in a stop reply, and
`ProcessGDBRemote::SetThreadStopInfo` puts those bytes straight into the
memory cache. When a range covers a breakpoint lldb manages itself, the
cache then holds the trap opcode, and every later read of that address
returns the trap instead of the instruction underneath. However, A read
reply does not have this problem: `ReadMemoryFromInferior` calls
`RemoveBreakpointOpcodesFromBuffer` before returning. The expedited path
never did, so this fix adds `Process::AddCacheData` to do the same and
use
it at the two places that cache expedited memory.
`TestWriteOverSoftwareBreakpoint.py` catches this once the stub
expedites a
range that covers the breakpoint:
```
AssertionError: bytearray(b'\x00\x00 \xd4') != bytearray(b'\xcd\x00\x00\x90')
```
`00 00 20 d4` is AArch64 `brk #0`. The test writes `0xcd` over the first
byte at the site, continues to it, and reads back. Only the lldb-managed
case fails; with an external breakpoint the stub hides its own trap.

[Clang][Parser] Accept contextual _except in MS compatibility mode (#223551)
Clang already accepts _try, _finally, and _leave under
-fms-compatibility, but rejects the corresponding _except spelling
because __except is recognized contextually by the parser rather than as
a reserved token.
This patch extends the contextual handler check to accept _except in
Microsoft compatibility mode and uses that check consistently in SEH and
C++ try-handler parsing. _except remains an ordinary identifier outside
the handler position, and -fms-extensions alone does not enable the
alias.
The change is limited to parsing; it does not modify SEH lowering, LLVM
IR, optimization, or runtime behavior.

[lldb] Surface GetIndexOfChildWithName errors instead of dropping them (#224059)
`ValueObjectSynthetic::GetChildMemberWithName` and
`SBValue::GetIndexOfChildWithName` called `llvm::consumeError` on the
`llvm::Expected` returned by `GetIndexOfChildWithName` and reported the
failure as a null `ValueObjectSP` / `UINT32_MAX`, so the reason a lookup
failed never reached anyone. Log them instead: `LLDBLog::DataFormatters`
from ValueObject and formatter code, `LLDBLog::API` at the SB boundary.
That is the convention `BlockPointer.cpp` and `LibCxx.cpp` already
follow.
Also, in `ValueObjectSynthetic::GetIndexOfChildWithName`:
- A front-end with `TypeOptions::eTypeOptionCustomSubscripting` that
failed to find the child left `index` at its `SIZE_MAX` initializer,
dropped the front-end's error unread, then cached `SIZE_MAX` in
`m_name_toindex` and returned it as a valid index. Return the
front-end's error instead.
- Call `GetNumChildren(max)` rather than
`GetNumChildrenIgnoringErrors(max)` for the `"[N]"` subscript bounds
check and propagate the error, so a child count that fails to compute is
no longer reported as a subscript that is out of range.
- Return early on a cache hit rather than falling through a chain of
else-if branches that retested `found_index`.
Lower-cases the two `"Type has no child named"` messages in
`TypeSynthetic.h` for consistency with every other instance of that
string.

[Clang] Fix __builtin_clear_padding() for bitfields (#216063)
This patch fixes the padding clearing logic for bitfields.
The padding clearing logic for bitfields is wrong for these cases:
- Over-sized bitfields don't have their padding bits recognised as
such.
- In big endian mode, the occupied bits are wrongly determined because
the different byte order is dismissed.
A big number of new tests have also been added to cover many different
scenarios that involve bitfields. Preexisting tests had their check
patterns regenerated with the updater script.

WebAssemblyCoalesceFeaturesAndStripAtomics doesn't really need to
construct a full new subtarget for its purpose and can directly take the global
subtarget feature bits. This pass is also doing quite a lot of other bad things,
like mutating the TargetMachine.

This change adds error checking to verify that only these cleanups are
on the EH stack when a musttail call is encountered and updates the CFG
flattening pass to add special handling that avoids routing musttail
call returns through the cleanup handler.

[IR] Provide intrinsics for speculative loads (#179642)
Introduce two new intrinsics to enable vectorization of loops with early
exits that have potentially faulting loads.
1. `@llvm.speculative.load` - perform a load that may access memory
beyond the allocated object. It must be used in combination with
`@llvm.can.load.speculatively` to ensure the load is guaranteed to not
trap. The number of accessible bytes must be provided, either as IR value
or via an oracle function.
2. `@llvm.can.load.speculatively` - Returns true if it's safe to
speculatively load a given number of bytes from a pointer. The semantics
are target-dependent. On some targets, this may check that the access
does not cross page boundaries, or stricter checks for example on
AArch64 with MTE, which limits the access size to 16 bytes.
`@llvm.speculative.load` is lowered to a regular load in SelectionDAG
without MODereferenceable.
`@llvm.can.load.speculatively` is lowered to regular IR in PreISel
lowering, using a target-lowering hook. By default, it conservatively
expands to false.
These intrinsics should allow the loop vectorizer to vectorize
early-exit loops with potentially non-dereferenceable loads.
This has previously been discussed in
https://github.com/llvm/llvm-project/pull/120603 and is similar to
nikic's https://hackmd.io/@nikic/S1O4QWYZkx.

[BoundsSafety][NFC] Allow CountAttributedType's count to be filled in later (#223267)
Prepare CountAttributedType so its count expression can be supplied
after the node is created, which the new late-parsed counted_by
mechanism needs: the type is built when the attribute is seen, but its
argument isn't parsed until the enclosing record is complete.
- Drop the TrailingObjects coupled-decl storage in favour of an
ASTContext-allocated array held by the ArrayRef the base class already
has, so the decls can be attached after construction.
- Add CountAttributedType::setCountExpr for in-place completion.
- Add ASTContext::getIncompleteCountAttributedType (count-less, not
uniqued) and completeCountAttributedType. Incomplete nodes are not
registered in ASTContext.Types until completed, so a node abandoned with
a null count is never reachable.
No functional change: getCountAttributedType still builds a
fully-formed, count-carrying type as before.
This is an adjusted direction from the previous attempt to create a
place holder type (LateParsedAttrType) and rebuild it once late parsing
is done (https://github.com/llvm/llvm-project/pull/212906) based on the
feedback from @cor3ntin
https://github.com/llvm/llvm-project/pull/212906#issuecomment-5532012528.
Creating a CountAttributedType in the first pass and filling in the
count expression in the second pass has a benefit that the types
(including the enclosing types) won't need to be reconstructed, allowing
to drop TreeTransform.

[ConstantFolding] Fold vector.partial.reduce.add constants (#212112)
This patch adds constant folding support for `llvm.vector.partial.reduce.add`.
The intrinsic leaves the grouping of input elements into result lanes
unspecified. This implementation uses the deterministic grouping
selected by
the generic lowering in `TargetLowering::expandPartialReduceMLA`: input
element `I` is accumulated into result lane `I % NumAccElts`.
Tests cover:
* Constant accumulator and input vectors
* Non-constant accumulator and input operands
* Poison and undef elements
* Different reduction ratios
* Negative values
* Integer wraparound
Fixes #211558

[libc] Read passwd records into a growable buffer (#224149)
Switch getpwent, getpwnam, and getpwuid to use DynamicBuffer so that
passwd records of arbitrary length are supported without fixed size
limits.
A single static DynamicBuffer and struct passwd are reused across
getpwent, getpwnam, and getpwuid per POSIX, and endpwent closes the file
stream without freeing the buffer so pointers returned prior to endpwent
remain valid.
The reentrant lookups (getpwnam_r and getpwuid_r) remain non-allocating
and return ERANGE when the caller's buffer is too small.
* Switch non-reentrant pwd lookups and iteration to DynamicBuffer
* Remove fixed 1024-byte buffer limit from pwd_utils
* Keep getpwnam_r and getpwuid_r non-allocating
* Update hermetic unit tests for long passwd records

Mix bits in FileID::getHashValue() (#223794)
FileID's identity hash was fine under DenseMap's old quadratic probing,
but #200595 switched DenseMap to linear probing with backward-shift
deletion. FileID's bucket index under an identity hash is just its low
bits, so two runs of file IDs can map to the same buckets, which can
turn into a long clustered probe chain under linear probing.
Multiply by 37 to spread the low bits, which matches
SourceLocation::getHashValue(). This fixes a 2.6x compile-time
regression observed with -Wdocumentation on an ObjC++ file.

[CodeGen][AArch64] Avoid duplicate hints in register allocation (#219007)
Duplicate register allocation hints cause AllocationOrder to yield
duplicate physical register candidates. For fixed-capacity eviction
advisors like MLEvictAdvisor (MaxInterferences = 32), this leads to
out-of-bounds array indexing and assertion failures.
In commit 0756e5985f0c, TargetRegisterInfo::getRegAllocationHints was
hoisted to the top of AArch64RegisterInfo::getRegAllocationHints, but
fallthrough paths invoked it a second time on an already-populated Hints
vector, duplicating copy hints for standard GPRs.
This patch:
1. Returns ConsiderOnlyHints on fallthrough in
AArch64RegisterInfo::getRegAllocationHints instead of calling
TargetRegisterInfo::getRegAllocationHints a second time.
2. In TargetRegisterInfo::getRegAllocationHints, deduplicates directly
against Hints instead of using a transient local set.
3. Adds regression test coverage for AArch64 MLRegAlloc eviction
advisor.
There are other issues lurking across LLVM where duplicate Hints are
created; it was decided in review of this PR to follow up with changing
the interface so that Hints is a SmallSetVector.

[libc] Add struct group header and group line parser (#224208)
Introduce the POSIX struct group header and grp_utils parser module for
colon-delimited group records.
Unlike struct passwd, struct group carries a null-terminated char**
member pointer array (gr_mem). parse_line<struct group> handles placing
the gr_mem pointer array into the aligned scratch span directly:
* Fixed-buffer callers (such as reentrant lookups) report ERANGE if the
provided scratch span cannot hold the member pointers.
* Growable DynamicBuffer callers grow the buffer when parse_line returns
ERANGE and retry before parsing in place.
* Add struct_group header in hdr/types/struct_group.h
* Expose libc.include.grp in Linux arm and i386 headers.txt
* Add grp_utils parser and database helpers in src/grp/
* Add unit tests in test/src/grp/grp_utils_test.cpp

Log Message:
-----------
Silence compiler warning
Use CompareSigned directly for operator overloads
get instead of coerce
Coerce -> getWord
incompatible instead of incomparable
Do no allow implicit conversion
Method name capitalization
Use GetBasicString and permit nullstate behavior
Hide constant template
Remove stray backstlash
