[AMDGPU] Preserve metadata in all barrier lowering paths (#191916)
Extend copyMetadata to every call-to-call replacement in
AMDGPULowerIntrinsics, not just the single-wave s_barrier →
wave_barrier path. This covers:
- s_cluster_barrier → wave_barrier (single-wave)
- s_cluster_barrier → signal_isfirst + wait + signal + wait (multi-wave)
- s_barrier → signal + wait (split barriers)
Add GFX11 and GFX12 RUN lines and test functions for all lowering
paths to verify metadata preservation.

This reverts commit 4abb927bacf37f18f6359a41639a6d1b3bffffb5.
The code is not needed since 121f5a96ff38 because the C compiler is now
always just-built clang in in-tree build. In addition, CMAKE_AR is
llvm-ar and CMAKE_RANLIB is llvm-ranlib.

[MLIR][Python] Migrate `result(infer_type=True)` to a new field specifier (#191849)
Currrently the signature of `result(..)` is:
```python
result(*, infer_type: bool = False, default_factory: Callable[[], Any] | None = None, kw_only: bool = False) -> Result
```
so when users use `result(infer_type=True)`, the type checkers will
still get `kw_only=False` (from the signature), but actually the
`kw_only` should be `True` (it should follow the value of `infer_type`).
users can use `result(infer_type=True, kw_only=True)` but it's
unnecessarily verbose.
So it may introduce an incompatibility when we start to use
`dataclass_transform`. currently it's fine because we just don't use
`dataclass_transform`. But when we use, we may require a breaking
change.
This PR migrates such use to a new field specifier named
`infer_result()`.

Using -fopenmp uses the default openmp lib, which defaults to libomp but

when using default, but fails downstream if configured for something
else, like libgomp.

[ToolChains][FreeBSD] Set default Linker to LLD for FreeBSD (#190596)
When the linker is specified as ld, toolchain applies special handling
by invoking (triple)-ld instead of resolving ld via standard PATH
lookup. This causes GNU ld installed via the system package manager to
take the precedence (since (triple)-ld appears earlier in the search
path), effectively overriding ld.lld.
As a result, we set the default Linker on FreeBSD to ld.lld to indicate
we want to use lld by default.

Log Message:
-----------
[flang][OpenMP] Avoid marking named main programs as declare target (#190250)
A bare `!$omp declare target` could incorrectly mark `_QQmain` as
`omp.declare_target` when it appeared in an interface body inside a
named
main program. That pulled host-only callees into device compilation and
caused offload link failures.
Fix this by skipping main programs in the implicit-capture path.
Also add a regression test for the named-main interface case and update
`real10.f90` to use a valid container for the bare `declare target`
form.
This fixes offload link failures where `_QQmain` was incorrectly treated
as
a device function and pulled in host-only symbols such as Fortran I/O
runtime calls.
Minimal reproducer:
```fortran
program named_main
interface
subroutine sub_a(x)
!$omp declare target
integer, intent(inout) :: x
end subroutine
end interface
integer :: v
!$omp target
call sub_a(v)
!$omp end target
end program

the limitations of doing this manually at every new release (adding the

this is the only low-risk solution for now.

[DAG] Add funnel-shift matchers to SDPatternMatch (Fixes #185880) (#186593)
Add new SelectionDAG pattern matchers for funnel shifts:
- m_FShL and m_FShR as ternary wrappers for ISD::FSHL/ISD::FSHR
- m_FShLLike and m_FShRLike to match:
-- direct FSHL/FSHR nodes
-- ROTL/ROTR equivalents (binding both X and Y to the same rotate operand)
-- OR(SHL(X, C), SRL(Y, BW - C)) forms (including commuted OR)
Also add unit tests covering positive and negative cases for:
- direct funnel-shif matching
- rotate equivalence matching
- OR-based funnel-shift-like patterns

[AVX-512] Fix for disjoint-or-fold (VGF2P8AFFINEQB) (#190896)
Fixes #190502
Added implementation of helper combineOrWithGF2P8AFFINEQB and wired the logic with combineOrXorWithSETCC:
Fold: (GF2P8AFFINEQB(X, Y, Imm) or_disjoint SplatVal) -> GF2P8AFFINEQB(X, Y, Imm ^ SplatVal)
When OR is disjoint (no common bits), the splat constant can be folded directly into the GF2P8AFFINEQB immediate via XOR.

[LV] Remove legacy selectVectorizationFactor and assert (NFCI) (#190838)
Almost all recipes now go through ::computeCost to properly compute
their costs using the VPlan-based cost model. There are currently no
known cases where the VPlan-based cost model returns an incorrect cost
vs the legacy cost model. I check the remaining open issues with reports
of the assertion triggering and in all cases the VPlan-based cost model
is more accurate, which is causing the divergence.
There are still some fall-back paths, mostly via precomputeCosts, but
those cannot be easily removed without triggering the assert, as the
VPlan-based cost model is more accurate for those cases. An example of
this is https://github.com/llvm/llvm-project/pull/187056.

[AArch64] Hint regalloc to choose distinct predicate for MATCH/CMP (#190139)
For some cores it is preferable to choose a destination predicate
register that does not match the governing predicate.
The hint is conservative in that it tries not to pick a callee-save
register if it's not already used/allocated for other purposes, as that
would introduce new spills/fills. Note that this might be preferable if
the instruction is executed in a loop, but it might also be less
preferable for small functions that have an SVE interface (p4-p15 are
caller-preserved).
It is enabled for all cores by default, but it can be disabled by adding
the `disable-distinct-dst-reg-cmp-match` feature. This feature can also
be added to specific cores if this behaviour is undesirable.

[mlir][tosa] Optimize non-narrowing float casts (#191439)
Extend the existing NonNarrowingCastsOptimization to also cover casts
between floating point types f32, f16, bf16, f8E4M3FN and F8E5M2. Avoid
introducing direct casts between f8 types since those are not allowed in
TOSA.
Also expand the set of cases that are considering non-narrowing by only
checking if the cast we're trying to remove is non-narrowing. Example
i16 -> i32 -> i8 would have been rejected before, but it is now safely
converted to a single i16 -> i8 tosa.cast, since the behaviour should
identical for the entire input space.
Finally disallow the optimization in the case when the cast that we
would remove involves integer types of different signedness.

[CoroEarly][IR] Clarify semantic of llvm.coro.end (#191752)
We introduced a workaround for the following pattern in #139243:
``` LLVM
define void @fn() presplitcoroutine {
%__promise = alloca ptr, align 8
...
coro.ret:
call void @llvm.coro.end(ptr null, i1 false, token none)
store ptr null, ptr %__promise, align 8
ret void
}
```
where DSE considers `__promise` dead after the return and eliminates the
store, leading to a miscompilation.
However, after #151067, the problematic pattern is gone. And it
currently looks like:
``` LLVM
gro.conv:
store ptr null, ptr %__promise, align 8
br label %after.gro.conv
after.gro.conv:
br i1 %body.done, label %coro.cleanup, label %coro.ret
coro.ret:
call void @llvm.coro.end(ptr null, i1 false, token none)
ret void
```
DSE cannot eliminate the store because `__promise` escapes through
`coro.id`, and `coro.end` post-dominates the store. It turns out that
accessing the coroutine frame after `coro.end` is not safe. This patch
proposes clarifying the semantics of `coro.end` and reverting the
workaround, as it confuses alias analyses. I have scanned the tests and
updated the uses of the coroutine frame after `coro.end`.

[LFI][AArch64] Add AArch64 LFI rewrites for system instructions (#186896)
This builds on the MCLFIRewriter infrastructure to add the
AArch64-specific LFI rewriter, which rewrites AArch64 instructions for
LFI sandboxing during the assembler step.
The initial rewriter handles system instructions: system calls, thread
pointer accesses, and also rejects modifications to reserved registers.

[lldb] Start using formatv() in RegisterContextUnwind (NFCI) (#191576)
This introduces two macros that do the same
`UnwindLogMsg()`/`UnwindLogMsgVerbose()` functions, but allow using
`formatv()`-style formatting. In addition to the benefits that the
`formatv()` function provides, this makes `log enable -F lldb unwind`
print the correct methods names from which the messages originate
(previously, it printed the name of one of those two helper methods).
I didn't replace all function calls with macros because there are too
many of them for one PR. This only replaces calls whose format string
contains no specifiers or only '%s' specifiers.

Replace calls to `UnwindLogMsg()`/`UnwindLogMsgVerbose()` with
`UNWIND_LOG`/`UNWIND_LOG_VERBOSE` macros introduced in 8417922c.
This replaces calls whose format string contains only '%d' and sometimes
'%s' specifiers, the rest will be addressed in a future patch.
As a result of this change, the `UnwindLogMsgVerbose()` is no longer
used and has been removed.

[LV] Don't skip VPlan cost model for div/rem instructions (#187056)
In LoopVectorizationPlanner::precomputeCosts we are skipping calculation
of costs using the VPlan cost model, instead preferring to use the
legacy costs. This helps to prevent the legacy and vplan cost model
assert firing, but really we should be encouraging full use of the VPlan
cost model.
I've created this initial PR to stop skipping the computation costs for
udiv/urem/sdiv/srem instructions. The VPlan costs seem to match up
nicely.
I intend to follow up with more PRs to move more opcodes across.

[mlir][EmitC] Convert math::RoundEvenOp, SqrtOp and RsqrtOp (#190158)
This patch extends the Math-to-EmitC conversion to cover `math.roundeven` and
`math.sqrt` for scalar f32/f64 values.
`math.roundeven` and `math.sqrt` are lowered to `emitc.call_opaque` using the
appropriate target-specific names:
C: `roundevenf` / `roundeven`, `sqrtf` / `sqrt`
C++: `std::roundeven`, `std::sqrt`
The patch also adds coverage for `math.rsqrt`. There is no direct EmitC
lowering for `math.rsqrt`; instead, the new tests verify the existing expansion
path through `-math-expand-ops=ops=rsqrt`, followed by `-convert-math-to-emitc`
and `-convert-arith-to-emitc`. This ensures the cross-dialect lowering sequence
produces the expected `emitc.constant`, `emitc.call_opaque`, and `emitc.div`
operations for f32/f64.
Unsupported cases remain unchanged. In particular, the new test documents that
f16 math.rsqrt is not lowered because math.sqrt is only converted for f32/f64.

[Clang] Enable multilib library support for Linux/Windows (#188584)
Summary:
This PR standardizes the logic used in the baremtal build to the common
toolchain interface. We then use this to handle the support in Linux and
Windows.
The multilib functionality allows us to select variant libraries based
off of a configuration file. For example, if the `multilib.yaml` file
detects `-fsanitize=address` it will automatically use the libraries
inside of `asan/` instead. These are layered so they do not necessarily
need to be complete library builds. More documentation can be found at
https://clang.llvm.org/docs/Multilib.html.
The motivation for this is so platforms like ROCm can use a more
standard way to ship debug / asan variants of libraries like OpenMP or
similar for both GPU an CPU targets.

[OMPIRBuilder] Pass work loop type in ident flags (#189347)
Flang uses the OMPIRBuilder to lower OpenMP constructs to LLVM IR.
When dealing with work sharing constructs, such as DO, DISTRIBUTE or
SECTIONS/SECTION, OMPIRBuilder needs to construct the call to the OpenMP
runtime, typically `__kmpc_for_static_init` or
`__kmpc_dist_for_static_init`.
The first passed flag to these functions is the `ident_t` struct,
defined in `kmp.h`. Most of the arguments are reserved for usage in
Fortran and unused in `openmp`. However, the `flags` argument is used
throughout the code base to identify specific constructs, such as the
type of work sharing construct.
In https://github.com/llvm/llvm-project/issues/112545, it was identified
that Flang does not provide the correct `ident_t` flags when calling
into e.g. `__kmpc_for_static_init`, causing the following runtime
warning to appear when the OpenMP Tools Interface is used:
```
OMP: Warning #189: OMPT: Cannot determine workshare type; using the default (loop) instead. This issue is fixed in an up-to-date compiler.
```
This PR adds a test, verifying that the work sharing constructs provide
the correct flags to the runtime call. The IR check for SECTIONS/SECTION
maps against `KMP_IDENT_WORK_LOOP`, as the OMPIRBuilder converts the
SECTIONS construct into a DO loop with a switch-case for every SECTION
clause.
In addition, `OMPIRBuilder` is modified, so that the work loop type is
passed via `ident_t.flags` to the respective
`__kmpc_for_static_init`/`__kmpc_dist_for_static_init` calls, letting
the test pass and the `libomp` warning disappear.
Wherever possible, provide the mapping based on the passed `LoopType`.
If not available, I implemented the decision based on the
`DistScheduleSchedType`, or in case of `applyDynamicWorkshareLoop`,
hard-coded this to `OMP_IDENT_FLAG_WORK_LOOP`.
---
As this is the first time dealing with `OMPIRBuilder`, I'm not sure if I
missed anything while implementing these changes.
If there's anything that can be improved here, e.g. with the ident flag
mapping, I'm very grateful for any feedback. I tried to implement this
with the best of my understanding based on taking a look at the existing
code and tests.
For example, I was not sure if adding a test to
`flang/test/Integration/OpenMP/` is the correct approach here, or if I
rather should try to modify
`unittests/Frontend/OpenMPIRBuilderTest.cpp`. In the end, the former
looked to me more straight-forward.

[clang][CIR][doc] Add auto-generated ClangIR documentation (#190354)
ClangIR has a collection of documentation pages that we want to upstream
as part of the main clang documentation. These pages are originally
available at https://clangir.org/, maintained in the [incubator
repository](https://github.com/llvm/clangir) which has been archived a
few months ago.
This patch makes a first step towards the upstreaming of ClangIR
documentation. The pages included in this patch are those automatically
generated from MLIR TableGen. Specifically, this patch makes the
following changes to the main clang documentation tree:
- It adds a new subdirectory `CIR` under `clang/docs` to hold all
ClangIR documentation. There are already 3 ClangIR design documents put
under `clang/docs`, and this patch moves all of them to this new
subdirectory.
- It touches the necessary CMake files and Python scripts to:
- Generate ClangIR language reference automatically from MLIR TableGen
when building the clang documentation with `CLANG_ENABLE_CIR=ON`.
- Incorporate these automatically generated documents (if any) into the
main clang documentation build tree.

[CIR] Inheriting Constructor/inheriting ctor inlining lowering (#191467)
In cases with inheritance/vertual tables/etc, we need to generate a
series of constructors to delegate to. There are a handful slightly
different cases where we need to generate these/generate calls to these,
so this patch does that lowering.
The test check-lines are a bit confusing thanks to the ordering
differences between declarations. However the LLVM/OGCG lines are copy
pasted (plus minor attribute differences), with the exception of the
call to a delegated constructor.
One thing of note here: There is a difference in behavior with the
delegated constructor, which is called out in the test in a comment.
Classic codegen has a bug where it correctly creates the declaration
without arguments (since this constructor is only for initializing the
vtable pointers, arguments aren't necessary). However, when
classic-codegen creates the call, it doesn't omit them.
This isn't a problem there, however in CIR, this causes us to fail the
verifier, so this fixes that in CIR, but leaves it alone in OGCG.

This kind optional is simpler to use when it needs to be represented in

avoids overflows. This applies to enums as well.
This also adds a single use of this new functionality, migrating users
of `std::optional<NullabilityKind>`
This optional used to be represented as two members in a bitfield, and
this simplifies things down to one.

This commit makes them conditionally-defined to not be building for

[lldb] Fix synthetic frame identity loss during incremental fetches (#191903)
When `SyntheticStackFrameList::FetchFramesUpTo` is called incrementally,
PC-less synthetic frames can end up with identical `StackID` values.
This happens because `num_synthetic_frames` is reset to zero on each
call, handing out duplicate call frame addresses. Since PC-less frames
all share `LLDB_INVALID_ADDRESS` as their PC, the `StackID` equality
check cannot distinguish them, and `ExecutionContextRef` resolves the
wrong frame.
The fix counts existing synthetic frames in `m_frames` before starting
the fetch loop so new frames receive unique call frame addresses.

[compiler-rt][TySan] Use pointer-width types for shadow memory ops (#191602)
The TySan runtime used uint64_t/int64_t casts for shadow memory pointer
arithmetic and interior-byte marker values. These are incorrect on
32-bit targets where pointers are 4 bytes: the shadow entries are
pointer-sized, so the offsets and marker values must also be
pointer-sized.
Replace uint64_t/int64_t with uptr/sptr (sanitizer_common's
pointer-width typedefs) throughout SetShadowType, GetNotAllBadTD,
GetNotAllUnkTD, and __tysan_instrument_mem_inst. This is a no-op on
64-bit targets (where uptr == uint64_t) and fixes shadow corruption on
32-bit targets.

[AArch64][TTI] Increase cost for masked memory operations requiring splitting (#191417)
If we need to split the memory operation, we'll also need to split the
mask.
This has a performance benefit in some cases when the loop vectorizer is
asked to maximize bandwidth and ends up choosing a VF that's too high
when tail folding. The costs of splitting the masks are not accounted
for in the current model, so this is something of a brute-force approach
to avoiding the wider VFs.

[OpenMP][OMPT] Revert `control_tool.c` changes from #191429 (#192069)
On s390x, the changes to `control_tool.c` cause a different return
address to be returned from the call to `print_current_address(0)`. Due
to the strictness of the current address returned by this call, this
lead to a test failure.
Since the return values of `omp_control_tool` are checked in separate
tests already, revert the changes to ensure that the return address
stays at the expected value.

[TargetLowering] Prevent expandVectorFindLastActive from creating illegal vector types during vector op legalization. (#190914)
This code needs to create a step vector but we only have a mask vector
type. If the step vector is too large it might not be an MVT. This
causes the getSimpleVT() call for getTypeAction to fail. We can replace
that with the EVT version of getTypeAction, but we'll still fail trying
to legalize the vselect. The getOperationAction query will return Expand
for non-simple VTs. ExpandVSELECT will try to unroll the vselect which
will fail for scalable vectors. We could hack that to not unroll
scalable vectors, but that would be a hack.
To fix this, split the FIND_LAST_ACTIVE into two if the step vector
needs to be split. Those will recursively legalize and eventually arrive
at a size we can create a valid step vector for.
One existing test changes because it created an illegal type which
happened to still be an MVT. This allowed getOperationAction to return
Legal, even though the type isn't legal.
Fixes the assertion mentioned in #187458.

fir.slice with a path component (z%re, z%im) was silently dropped by

layout must come from the projected box descriptor via

complex-array projections are handled here —
sizeof(complex<T>)/sizeof(T) = 2 is always exact for divsi. Derived-type
component projections bail out to downstream FIR-to-LLVM lowering where
strides can be non-integer.

[win] Add a flag to control the Control Flow Guard mechanism on Windows (#176276)
Windows Control Flow Guard (CFG) has two different "mechanisms" or
"patterns":
* Dispatch: the caller calls into the CFG function, which both checks
the target callee and then calls it.
* Check: the caller calls the CFG function which only checks the target
callee and then must separately call the callee.
LLVM has followed MSVC's pattern for selecting the mechanism based on
the target architecture. These defaults in MSVC are based on tests for
performance: Dispatch produces a smaller code size, whereas Check is
more friendly to branch predictors.
It is possible, however, for a given workload, call pattern or target
CPU that someone may want to select a different mechanism to use for
their code.
This change adds a new Clang and CC1 flag to force a CFG mechanism:
`-fwin-cfg-mechanism`. This can be set to `automatic` (lets LLVM choose
a mechanism), `force-dispatch` or `force-check`.
Also adds the support for the equivalent MSVC flag
`/d2guardcfgdispatch`.
NOTE: Arm64EC only supports the check mechanism. It should be noted that
MSVC emits the "dispatch" name for the call checker (for legacy reasons)
but uses the check mechanism.

The `MLProgramPipelineGlobals` pass crashed with a null pointer dereference

be resolved in the IR (e.g. an external function defined outside the module).
Instead conservatively bail out when a callee symbol cannot be resolved,
causing the pass to (preserving all loads/stores). This is consistent with
how Value-based callees are handled.

A first attempt at upstreaming this patch was made
[here](https://reviews.llvm.org/D154396). I hope I fixed everything
mentioned there.
I intentionally kept `/usr/local/` in the default lookup path. I
consider it the more practical option, and I’d prefer to have the patch
merged as is and revisit the FIXME later. If this is absolutely
unacceptable to the maintainers, I will happily drop it and keep it as a
local patch until we address the underlying issue.
@MaskRay, @brad0 as you already reviewed the original patch.

[mlir][quant] Print actual quant storage type when signed (#187300)
Without the fix, bytecode serialization roundtrip breaks for types that
don't have custom bytecode serializers and contain quant types, since
the fallback mechanism prints the type and the quant printer coerces
signed to signless types. E.g. `!custom<!quant.uniform<ui8:f32, 0.1>>`
will print as `u8` when serializing and later be created as a signless
`i8` when deserializing.

[CIR] Fix union RecordType::getTypeSizeInBits to return bits (#191516)
RecordType::getTypeSizeInBits for unions was calling
dataLayout.getTypeSize (which returns bytes) instead of
dataLayout.getTypeSizeInBits. This returned a value 8x too
small. Also handle the empty-union case where
getLargestMember returns nullptr.

[CIR] Add noundef to memchr declaration and call sites (#191457)
The memchr LLVM declaration created by MemChrOp lowering had no
arg_attrs, so the lowered IR was missing `noundef` on all three
parameters. OGCG emits `noundef` on them.
Adds `noundef` to both the `@memchr` declaration and each
`call @memchr` instruction.

[RISCV] Prevent emitting vsetvli with e32alt or e64alt. (#191960)
The e32alt and e64alt encodings for vtype are reserved.
Non-fp instructions ignore altfmt and we want to use that to avoid
vtype toggle when using load, store, slide, gather, etc. to manipulate
bf16 vectors. This is why we have a Demanded bit for AltFmt.
We need to make sure we don't keep the AltFmt set when we're changing
SEW to 32 or 64.
A new isValidVType function has been added to help catch illegal
vtype earlier.

This patch implementation is primarily focused on
- Lowering to LLVM IR, by generating appropriate kmpc_alloc() and kmpc_alligned_alloc() calls for variable(s) and before the end of scope generating kmpc_free() for the same variable(s).
- Also handled, usage of array variables in the OMP ALLOCATE directive.
- Define omp.allocate_free operation in MLIR and slight changes to existing MLIR definition of ALLOCATOR clause.
- Add test cases for variations of usage of OMP ALLOCATE directive and its clauses ALIGN and ALLOCATOR.

[lit] Add an option to lit which ratelimits progressbar output. (#186479)
Add a new option --min-output-interval, which ratelimits updates to the
progress bar.
When running Lit with the full curses progressbar, it updates both the
bar, and the status text below on every test completion. Running
check-llvm on my laptop runs about 44k tests and takes about 260 seconds
for a release build. Or about 171 tests/second on average.
Moreover, when ssh'd to another host, this generates quite a bit of
traffic. Using tcpdump, I measured the traffic for a run of check-llvm
and -clang. With all updates, its about 8.7 megabytes. With a rate limit
of 5 update/sec, this came down to 175 kilobytes. This can be
significant on slow/metered connections.
This patch adds an option to limit lit's output to once per a given
interval. This only affects the progressbar and status message below,
not any log messages above. It also does not affect anything when not
running with the full progressbar (eg outputting to a logfile).

[AArch64] Check Subtarget via STI in getInstSizeInBytes (#192089)
The InstSizes test (`llvm/unittests/Target/AArch64/InstSizes.cpp`)
destroys the Subtarget field early (`ST` created on the stack in
[`createInstrInfo`](https://github.com/llvm/llvm-project/blob/40a585e742ed6b28306d7511380079325ba1a003/llvm/unittests/Target/AArch64/InstSizes.cpp#L32)),
causing a use-after-free if it is used in `getInstSizeInBytes`. This
causes a failure when running the test with hwasan (reported by build
bot). To fix this, this PR switches to using `STI` instead of
`Subtarget` in `getInstSizeInBytes` for checking `isLFI`, which survives
for the lifetime of the test.
I think fixing the test itself (the root of the issue, as far as I can
tell) would be more involved. Perhaps I should open an issue for it
though?
I have tested the fix on an AArch64 machine with hwasan to confirm that
it resolves the issue.

[LLDB][Docs] List available settings (#168245)
This PR adds a documentation page that lists all available settings. The
page is automatically generated.
Having the settings listed in the online documentation makes it easier
to search for users. It also has the advantage of being indexed by
search engines.
To generate the docs, we first generate JSON out of the TableGen
definitions with `-dump-json`.
Once all properties are available as JSON, a Markdown file with the
merged documentation (`settings.md`) is generated. I chose Markdown over
RST, because some descriptions already use backticks, which would become
references in RST.
Currently, enum names/descriptions are not visible, because they're
defined in C++. In the future, these could be moved to TableGen as well.

[CIR] Raise IntType max bitwidth to match LLVM IR (#191499)
Follow-up to #188113 per @erichkeane's feedback about the 128-bit cap.
CIR's IntType was hard-limited to 128 bits, which meant any _BitInt
wider than that hit an errorNYI. LLVM IR goes up to 2^23 (about 8
million bits), and there are real tests/users at those sizes. This
raises CIR's limit to match and drops the guard that was working around
it.
Tests: added a _BitInt(256) global to bitint.c and a 1024-bit round-trip
to bitint.cir.

[NFC][SPIRV] Re-factor feature map initialisation for AMDGCN flavoured SPIR-V (#192067)
AMDGCN flavoured SPIR-V must support the union of all AMDGCN features,
as we cannot early adjudicate on this or that feature's availability. We
were hand filling in the feature map, which was error prone and led to
constant grind as new features were added. This patch moves to a
programmatic approach where we iterate through all AMDGCN GPUs and
collect features, thus establishing the union. With this change AMDGCN
flavoured SPIR-V will automatically pick up new features as they come
along.

[flang] Fixed issues in nested LICM. (#192117)
First change is to check the hoisting safety for all nested
operations of the candidate. This prevents hoistings of
region operations as in the added test.
When hoisting operations from nested regions we have to
check every parent region for `canMoveOutOf`, otherwise,
illegal hoisting may happen. This second change is NFC,
because all operations that support `OperationMoveOpInterface`
currently also support `LoopLikeOpInterface` and their regions
are not considered for nested hoisting. Anyway, it is worth
fixing it.

lookup is done on actual INTEGER/FLOAT LLTs. But hash values of
ANY_SCALAR do not match those of INTEGER/FLOAT, causing a failure.
Workaround is the use constexpr LLT, which encodes INTEGER/FLOAT LLT.

[CIR] Fix heap-use-after-free in IndirectBrOp lowering (#191949)
The previous code called op->getBlock()->eraseArgument(0) to remove a
block argument when the poison attribute was set (unreachable block with
no predecessors). This directly mutated the IR, freeing the
BlockArgument while the MLIR dialect conversion framework still held
references to it. When the framework later replayed changes in
applyRewrites(), it dereferenced the freed BlockArgument, causing a
heap-use-after-free detected by ASAN.
Found by running check-clang-cir under ASAN
(test: clang/test/CIR/CodeGen/label-values.c).
The fix removes the eraseArgument call entirely. The MLIR conversion
framework tracks block arguments and handles their lifecycle. A block
with no predecessors naturally produces no PHI node in LLVM IR, so
manual removal was unnecessary.
Additional cleanup:
- Use adaptor.getAddr() directly instead of creating an unnecessary
BitcastOp (CIR ptr already converts to LLVM ptr).
- Use adaptor.getSuccOperands() instead of op.getSuccOperands() to
ensure successor operands go through type conversion.
- Use replaceOpWithNewOp instead of separate create + replaceOp.

[flang][OpenACC] Propagate acc.declare attribute to fir.global for USEd module variables (#192141)
When a module with `!$acc declare` is compiled separately from the
program that USEs it, `declareGlobal()` creates `fir.global` without the
`acc.declare` attribute. This causes implicit data mappings to override
device data that should already be present via `acc declare`.
The fix reads the symbol's `AccDeclare`/`AccCreate`/`AccCopyIn`/etc.
flags (already set from the `.mod` file by semantics) and attaches the
`acc.declare` attribute to the `fir.global`.

[analyzer] Fix alignment of entries in -analyzer-help (#190570)
Fix a formatting bug in `AnalyzerOptions::printFormattedEntry` (used by
`clang -cc1 -print-analyzer-options`), which led to misalignment of a
checker description.
This commit ensures that `printFormattedEntry` inserts a newline in the
corner case when the length of the name of a checker is exactly equal to
`EntryWidth`. (In this situation the old code inserted a space between
the name and the description, so this description was not aligned with
the other descriptions.)
Additionally this commit also fixes the corner case where the pad before
the checker name (specified by `InitialPad`) is 0. Before the fix, due
to `llvm::raw_formatted_ostream::PadToColumn` logic, `InitialPad = 0`
still added one space character as padding before the checker name.
Fortunately `InitialPad = 0` was never used in the program, so this bug
was not visible to the user.
These changes are both tested by the freshly added unit tests.

[flang][CodeGen] Fix address space mismatch for CUF globals in AddrOfOpConversion (#190408)
AddrOfOpConversion in CodeGen.cpp only handled `LLVM::GlobalOp` when
determining the address space for `llvm.mlir.addressof`. When the global
was still a `fir::GlobalOp` (not yet converted), it fell back to address
space 0, breaking CUF constant globals (addr_space 4) and AMDGPU targets
(global addr_space 1).
This extends the upstream fix (#192111, which only covered Constant) to
also handle Shared and Managed CUF data attributes, and returns
`std::nullopt` instead of 0 for non-CUF globals so the target's default
address space is preserved.

[lldb] Fix deadlock when scripted frame providers load on private state thread (#191913)
Frame providers are an overlay on top of the parent reality (the
unwinder stack). The private state thread (PST) manages the stop of that
parent reality, so the correct view for PST logic IS the parent --
providers should only be applied once the process has settled and
clients query the stopped state.
When a scripted breakpoint's `was_hit` callback calls
`EvaluateExpression` on the PST, `RunThreadPlan` spawns an override PST
(Thread B) and reassigns `m_current_private_state_thread_sp` to it. Two
threads then need to see parent frames:
- Thread B (override PST): processes stop events via
`HandlePrivateEvent` -> `ShouldStop` -> `GetStackFrameList`. If it loads
a provider, the provider's Python code can acquire locks held by Thread
A, causing a deadlock.
- Thread A (original PST): processes events inline via
`FindNextEventInternal` -> `DoOnRemoval` -> `GetStackFrameList`. After
the override is created, `CurrentThreadIsPrivateStateThread` no longer
recognizes Thread A (it checks against
`m_current_private_state_thread_sp`, which now points to Thread B).
The existing re-entrancy guard in `GetStackFrameList` (e1cd558) only
triggers when a provider is already active. In the deadlock scenario,
provider loading is being initiated for the first time, so the guard
does not trigger.
This patch introduces `PrivateStateThreadGuard`, an RAII guard that sets
a `thread_local` flag checked by `GetStackFrameList` to return parent
frames instead of loading providers. The guard is activated in two
places:
- `RunPrivateStateThread`: for override PSTs only (identified via a new
`is_override` flag on `PrivateStateThread`). The original PST does not
set the guard here, so normal stepping still sees provider-augmented
frames.
- `RunThreadPlan`: for the original PST, scoped to the event processing
window when an override has been spawned.

[runtimes] Aggregate per-target runtime checks in top-level check-${runtime_name} (#191743)
When a per-target runtime build exports a

check-${runtime_name} target depend on it, creating
check-${runtime_name} on demand (it may not exist).
This applies regardless of whether the runtime comes from the default
LLVM_ENABLE_RUNTIMES set or from a target-specific
RUNTIMES_<target>_LLVM_ENABLE_RUNTIMES override.
This allows a single `check-${runtime_name}` command to trigger all
per-target tests for that runtime.

Make GSYM 64 bit safe and add a new version 2 of the GSYM files (#190353)
# Motivation
GSYM files are approaching the need for 64 bit offsets in the GSYM
files. We also want to add more global data to GSYM files. Right now the
GSYM file format is:
```
Header
AddressOffsets
AddressInfoOffsets
FileTable
StringTable
FunctionInfos
```
The location of the `AddressOffsets`, `AddressInfoOffsets` and
`FileTable` are always immediately following the Header. The
`StringTable` is pointed to by the header and the header uses 32 bit
integers for the string table file offset and file size. The
`AddressInfoOffsets` are fixed at 32 bits as well. So with the current
format, we can't have any string or function info with an offset >= 4G.
# GSYM V2 design (64 bit safe and extensible)
This new design increments the GSYM version to 2 and we are adding a new
`GlobalInfoType` enum which allows us to specify the file offset and
file size of all of the things in the global data table to be 64 bit
safe. Everything is now in the global info data (listed below). The new
design is extensible: new global info types can be added in the future,
and the order that they appear in the file can be changed/optimized.
* UUID (optional)
* AddressOffsets table
* AddressInfoOffsets table
* File table
* String table
* FunctionInfo data
We are also adding a new `StringTableEncoding` enum so that new string
table encodings can be added in the future.
GSYM V2 files can be produced by using the new `--oputput-version=2`
option. For example:
```
llvm-gsymutil --convert my.dSYM -o my.gSYM --output-version=2
```
# Tests
**Unit tests**: Extended existing tests (`GSYMTests.cpp`) to cover both
v1 and v2. Added new V2 tests (`GSYMV2Tests.cpp`).
```
ninja DebugInfoGSYMTests SupportTests
unittests/DebugInfo/GSYM/DebugInfoGSYMTests

../llvm-project/llvm/test/tools/llvm-gsymutil/X86/elf-dwarf.yaml \
../llvm-project/llvm/test/tools/llvm-gsymutil/X86/mach-dwarf.yaml
```
**Parity tests to V1 (manual)**:
* All tests were conducted on a very large DSYM (9.24 GB) and the GSYMs
generated from it (3.42~3.57 GB).
* All correctness tests were conducted on both little-endian and
big-endian machines.
* **Data parity (on-par)**: The new gsymutil [generates the exact same
GSYM v1 file as the baseline
gsymutil](https://gist.github.com/royitaqi/746c15ec22725cf89a1f5c6d9fb396aa),
both using a single thread.
* **Performance parity/improvement (on-par; v2 convert is 2.8x
faster)**:
* **Parse + lookup**: The new gsymutil is [2% (GSYM v1 file) and 3%
(GSYM v2 file) slower than the baseline
gsymutil](https://gist.github.com/royitaqi/9789b92d63ae74a806c776f32a33e4fb)
(1.56s vs. 1.52s).
* **Convert**: The new gsymutil is [on par (GSYM v1 file) and 2.8x
faster (GSYM v2 file) than the baseline
gsymutil](https://gist.github.com/royitaqi/17aa69408bc5a3416fae9e192b1dc1ce)
(102s vs. 288s).
* **Memory footprint parity (on-par)**:
* **Convert**: The new gsymutil uses the same amount of memory as the
base line gsymutil (13 GB when converting a 2.52 GB DSYM; 42 GB when
converting a 9.24 GB DSYM) since the memory peak is in `finalize()`
which is before `encode()`.
* **Segment correctness (on-par)**: The new gsymutil [generates
segmented GSYM v2
files](https://gist.github.com/royitaqi/9bea5b3d50f13247d577ea91fbc6368a),
whose content
([seg1](https://gist.github.com/royitaqi/5b95a793b548f2f44edca250d64366b4),
[seg2](https://gist.github.com/royitaqi/f64730cbd1885ac9c0b9136e03e7742e),
[seg3](https://gist.github.com/royitaqi/2ce585fae910c57784cafafe4fb4cdcb))
match that of a [single GSYM v2
file](https://gist.github.com/royitaqi/475499477b9dbb1dea81f5d653ec39bf).

[SPIRV]Implementing PopCount for 16 and 64 bits (#191283)
`OpBitCount` only supports 32bit types. So this patch modifies the
codegen to follow a similar pattern as `firstbithigh` and `firstbitlow`.
On 8 and 16 bits, the parameters are zero-extended to 32 bits. With 64
bits it is bitcasting into 2xi32 types. The logic is adapted to larger
component counts as well.

sub-build, check-openmp target doesn't exist and there is build error
`unknown target 'check-openmp'` after 18f63d1375d0, which makes
top-level check-openmp depend on check-openmp-amdgcn-amd-amdhsa.
In openmp, the device targets only call add_subdirectory(device), which
doesn't calls construct_check_openmp_target() and check-openmp target
doesn't exist. `ninja check-openmp-amdgcn-amd-amdhsa` also fails with
the same error before 18f63d1375d0.
Fix by adding construct_check_openmp_target() for device targets as well.

[Hexagon] Add LTO options to Hexagon driver link args (#191336)
The Hexagon driver's constructHexagonLinkArgs() was not calling
addLTOOptions(). This meant that LTO plugin options weren't forwarded to
the linker.
This caused a crash when using ThinLTO with -fenable-matrix on
llvm-test-suite/SingleSource/UnitTests/matrix-types-spec.cpp:
LowerMatrixIntrinsicsPass did not run in the LTO backend because
-enable-matrix was not forwarded via -plugin-opt.
Add the addLTOOptions() call to both the musl and bare-metal code paths
in constructHexagonLinkArgs().

[sanitizer] Use close_range on Linux to close FDs in StartSubprocess (#191450)
Enable the close_range syscall on Linux when __NR_close_range is
available in kernel headers (Linux 5.9+). On older kernels, the
syscall returns ENOSYS and callers fall back gracefully.
This fixes the slow FD closing loop in StartSubprocess when
RLIMIT_NOFILE is high (e.g. 1B in Docker environments).

```

```
Not all use-sites were updated to pass an argument resulting in build
failures. I'm updating the errors in the FreeBSD and NetBSD plugins to
use formatv instead of expanding the C String, like what is done on
Linux, avoiding the issue entirely.

[llvm] Move libSupportHTTP to top-level libHTTP (NFC) (#191202)
The HTTP implementation depends on CURL and would preferably not be part
of the LLVM dylib. This was not possible as a nested library under
libSupport, because libSupport itself is part of the LLVM dylib. This
patch moves the HTTP code into a separate top-level library that is
independent from libSupport and excluded from the LLVM dylib.

[AMDGPU]Refactor `lowerWaveReduce` for maintainability (#189223)
The function to lower wave reduce pseudos is already quite
large ,and there are yet a few more operations to support.
Refactoring some of the code to make it more manageable.
Summary of changes:
1. Moved the expansion for `V_CNDMASK_B64_PSEUDO` to a
separate function. It's needed for 64 bit dpp operations.
2. Collapsed `getIdentityValueFor32BitWaveReduction` and
`getIdentityValueFor64BitWaveReduction` into a single
function which returns a 64 bit unsigned value.
3. Modified `getDPPOpcForWaveReduction` to also return
the `Clamp` opcode.
4. Added a lambda: `BuildRegSequence` and a static function
`ExtractSubRegs` as those code blocks are repeated with
little variation.
5. Moved logic for setting identity value in inactive lanes
to `BuildSetInactiveInstr`.

[ORC] Add MemMgr arg to LLJITBuilder::ObjectLinkingLayerCreator. (#192214)
LinkGraphLinkingLayer and ObjectLinkingLayer will start requiring a
jitlink::JITLinkMemoryManager argument in an upcoming commit. In
preparation for that, this patch threads a MemMgr argument through the
LLJITBuilder::ObjectLinkingLayerCreator factory type.
Note: This patch does not thread the argument through the C API
(LLVMOrcLLJITBuilderObjectLinkingLayerCreatorFunction) yet so as to not
break compatibility. All current users of the C API construct
RuntimeDyld instances, which would have to ignore this argument anyway.
If we don't update the
LLVMOrcLLJITBuilderObjectLinkingLayerCreatorFunction type before
RuntimeDyld is removed then that will be a good time to update it, since
all existing users were going to have to rewrite their code anyway.

[llvm adt] Use `__builtin_bswap16` in `byteswap()` when available (#190002)
The 32-bit and 64-bit branch of the code has the same pattern of using
`__builtin_bswapXX` when available (before trying to use
`_byteswap_XXXXX`). But the 16-bit branch doesn't do this (it only tries
to use the latter).
It seems `__builtin_bswap16` is a thing (see
[doc](https://gcc.gnu.org/onlinedocs/gcc/Byte-Swapping-Builtins.html)),
so I wonder if we just forgot to use it in the 16-bit branch.
Adding it and hope it helps (i.e. faster than the default shift-and-or
approach).

[MLIR][LLVM] Fix non-deterministic alloca order in SROA under LLVM_REVERSE_ITERATION (#192087)
AllocaOp::destructure iterated over usedIndices (SmallPtrSet) whose
order depends on pointer values, causing allocas for destructured
subslots to be emitted in a non-deterministic order when
LLVM_REVERSE_ITERATION is enabled. Sort indices ascending by integer
value before creating allocas to guarantee a stable output order. Update
four test cases in sroa-intrinsics.mlir whose CHECK patterns relied on
the old non-deterministic ordering.

[CIR] Implement 'ArrayInitLoopExpr lowering' in ExprAgg. (#192053)
This ended up being a fairly common pattern: a copy operation on a
structure with an array inside of it. Classic-Codegen has a few
different ways of initializing/copying an array, of which this is one.
However, this patch uses the array-init functionality we already have.
This ends up being a bit verbose, but will make sure we don't have to
worry about separately handling throwing types/etc for this AST node.
Additionally, this has to handle the ArrayInitIndexExpr, but that is as
simple as making sure we properly cache the index value when doing our
initialization.

Similar to the previous Expr-change that I made, this does the same with

effectively a copy/paste of the classic-codegen, so it maintains our
current invariants/assumptions about changes via emitLoadOfLValue.

[CIR] Lower PsuedoObjectExpr LValues (#192108)
This ends up being pretty much copy/paste from classic-codegen, so it

I DID switch the return type of the helper function to be a variant
instead of a manually-put-together pair, and switched to range-for, but
otherwise it should be identical.
However, I was uanble to reproduce a few of the branches, so NYIs were
left in place until we can figure them out. At least some of them are
going to be for RValue versions.

[MLIR][Bufferization] Fix foldMemRefCasts dropping ranked return type for unranked->ranked cast (#189249)
When one-shot-bufferize with bufferize-function-boundaries is used and a
function returns a ranked tensor that is produced by casting from an
unranked intermediate (e.g. a call to a function returning
tensor<*xf32>), the foldMemRefCasts post-processing step incorrectly
unpacked the memref.cast from unranked to ranked memref, downgrading the
function return type to the unranked memref type and using the unranked
value as the return operand.
The fix is in unpackCast(): do not unpack a cast whose source is an
unranked memref and whose result is a ranked memref, since doing so
would lose type specificity.

[Flang] Fix statement-function shadowing to avoid false unresolved-symbol internal error (#189360)
When a statement function shadows a host-associated internal procedure
name, HandleStmtFunction creates a local symbol but leaves name.symbol
pointing to the host SubprogramNameDetails.
Because of that stale pointer, AnalyzeStmtFunctionStmt exits early (it
expects SubprogramDetails), so the RHS is never resolved and flang emits
a false `internal error: "Internal: no symbol found".` Clearing
name.symbol after creating the local shadow symbol lets it re-resolve
correctly and fixes the issue.

[LifetimeSafety] Propagate origins through explicit cast expressions (#192180)
Before this PR, `FactsGenerator` handled cast nodes with
`VisitImplicitCastExpr` (`CastKind` switch case) and
`VisitCXXFunctionalCastExpr` (handle`gsl::Pointer` types). Other
explicit casts (`CStyleCastExpr`, `CXXStaticCastExpr`, ...) had no
handler, so origin was silently dropped. This is the root cause of
#190912: the dangle in `a = StringView(s);` is missed even though the
equivalent `StringView tmp(s); a = tmp;` is reported.
The policy for "does this cast propagate origin?" is a function of
`CastKind`, independent of whether the cast is implicit or explicit.
This PR replaces `VisitImplicitCastExpr` with a generic `VisitCastExpr`.
`VisitCXXFunctionalCastExpr` is retained only to preserve the
`handleTestPoint` logic, then delegates to `VisitCastExpr`.
This mirrors `clang/lib/AST/ExprConstant.cpp`, where each evaluator
implements only `VisitCastExpr` and switches on `CastKind`; the few
ExprClass-specific overrides (e.g., `VisitCXXDynamicCastExpr`) exist
solely to attach constexpr-validity diagnostics before delegating back.
Scope: the set of `CastKind`s that propagate origin is unchanged.

[Clang] Diagnose `co_await` expressions in default arguments of nested functions (#191817)
co_await/co_yield expressions are not allowed in default arguments. We
were checking they do not appear outside of function contexts, which
include default arguments of the corresponding function, but it missed
default arguments of functions declared in the body of another
functions.
Because parsing default argument isn't done in a dedicated scope, we do
additional checks in `ActOnParamDefaultArgument`. Because the checks is
done in two places, we cannot introduce a more precise diagnostic.
It might be worth considering a parse scope for default arguments in the
future.

[lldb][Docs] Fix presentation of some default values (#192239)
There were two bugs with the display of default values:
1. If a default value contains a backtick, that would render
incorrectly. For example
[`disassembly-format`](https://lldb.llvm.org/use/settings.html#disassembly-format).
Fixed by doing the wrapping when we generate the Markdown instead of
when parsing the directive. MyST will already parse the content of the
directive as Markdown. We can escape backticks inside the string by
changing the fence. Markdown can take any number of backticks at the
start as long as they match the amount at the end
([spec](https://spec.commonmark.org/0.31.2/#code-spans)).
2. When the docs were built on Windows, UTF-8 was not correctly picked
up, because the default encoding isn't utf8 there.
[`separator`](https://lldb.llvm.org/use/settings.html#separator) was one
example (renders correctly on the Website but not on my machine).

[llvm-jitlink] Hold Session::ObjLayer by unique_ptr. (#192253)
This will simplify the Session construction process when we remove
jitlink::JITLinkMemoryManager ownership from ExecutorProcessControl in
an upcoming patch.
(Reason: ObjectLinkingLayer's constructor will require a
JITLinkMemoryManager, which we'll want to cerate after the
ExecutionSession has been initialized. Creating a JITLinkMemoryManager
is generally a fallible operation, so we want to be able to bail on
construction of the ObjectLinkingLayer entirely if we can't create a
memory manager for it).

It's a bit conservative, and we could refine it further, but I'd take an

[CIR] Handle irregular partial init destroy (#192158)
This implements CIR handling for the case where an array of a destructed

address of the last successfully constructed element must be loaded from
a temporary variable before the partial array destroy loop can begin.
In classic codegen this shares its implementation with the general array
ctor/dtor handling, but in CIR we have dedicated operations to abstract
array ctors/dtors, so the implementation of the irregular partial
destruction happens in a different place in codegen.

[CIR] Handle full expression cleanups in conditional branches (#191479)
This adds CIR support for handling full expression cleanups in
conditional branches. Because CIR uses structured control flow, it was
necessary to handle these cleanups differently than is done in classic
codegen. CIR speculatively creates a cleanup scope when an
ExprWithCleanups contains a conditional operator and maintains a
dedicated stack of these deferred cleanups, which is added to the
cleanup scope at the end of the full expression with an active flag used
to control whether the cleanup should be executed based on any branches
that may have been taken during the conditional expression evaluation.
This is similar to the mechanism used for lifetime extended cleanups,
but the timing of when the cleanups are moved to the main EH stack is
different, so we need to maintain two different pending cleanup stacks.
We are able to use the same PendingCleanupEntry class for both.

[mlir][OpenMP] Fix teams reduction assert with sibling distributes (#191475)
Avoid double-mapping teams reduction block arguments when multiple
sibling `omp.distribute` ops appear under the same `omp.teams`.
Replace `teamsReductionContainedInDistribute` with
`getDistributeCapturingTeamsReduction`, which returns the unique
`omp::DistributeOp` containing all non-debug uses of the teams reduction
block arguments, or null if no such distribute exists. In that case,
reduction setup falls back to the teams op.
This ensures only the owning distribute handles reduction setup and
prevents `moduleTranslation.mapValue()` from being called multiple times
for the same block arguments.

[MLIR][Vector] Fix WarpOpScfForOp and WarpOpScfIfOp leaving invalid ops after region moves (#188951)
WarpOpScfForOp::matchAndRewrite called mergeBlocks() to move forOp's
body block into the inner WarpOp. mergeBlocks() erases the source block,
leaving forOp with an empty body region (0 blocks). Since scf.for
requires exactly 1 body block, IR verification fails with "region with 1
blocks" after the pattern succeeds. Additionally, when forOp had no init
args, the pattern was missing the scf.yield terminator in the new ForOp.
WarpOpScfIfOp::matchAndRewrite had the same issue: takeBody() emptied
the ifOp's then/else regions, leaving scf.if with 0 blocks.
Fix:
- Restore the conditional scf.yield creation (only when newForOp has
results).
- After merging/taking the regions, replace the remaining op's results
with ub.poison and erase the now-invalid op from the new WarpOp's body.

[AMDGPU][Scheduler] Fix non-monotonic SlotIndex after schedule revert (#192039)
modifyRegionSchedule restores the original instruction order by splicing
MIs before RegionEnd. When an MI is already at the expected position
(MII == RegionEnd) its SlotIndex was left unchanged, even though earlier
splices may have shifted neighboring indices. This could leave a stale,
lower-numbered slot on a non-moved MI, breaking SlotIndex monotonicity
and corrupting LiveIntervals.
The corruption surfaced as a "register isn't live" assertion in
GCNDownwardRPTracker when PreRARematStage's finalizeGCNSchedStage
globally reverted regions that were already locally reverted by
checkScheduling.
Fix by calling LIS->handleMove for non-moved MIs whose SlotIndex has
become non-monotonic (PrevIdx >= MI_Idx). Additionally, track whether
checkScheduling already reverted a region and skip the redundant global
revert in finalizeGCNSchedStage.

[InstCombine] Generalize zext(add X, -C) + C folding (#191723)
This patch generalizes an existing InstCombine optimization:
zext(X - 1) + 1 → zext(X)
to support arbitrary constants C:
zext(X - C) + C → zext(X)
when X is known to be >= C using KnownBits analysis.
This avoids missed simplifications for non-unit constants while ensuring
correctness under wrap semantics.
Includes test coverage for:
- Positive case where the fold applies
- Negative case where the fold must not apply
### Correctness Proof
We consider the transform:
zext(add(X, -C)) + C → zext(X)
under the conditions:
1) X u>= C (unsigned comparison)
2) C fits in the bitwidth of X (i.e., representable in NarrowBW bits)
The inner operation is performed in the narrower bitwidth n:
add(X, -C) = (X - C) mod 2^n
Since X u>= C, the subtraction does not underflow, so:
(X - C) mod 2^n = X - C
Applying zero extension:
zext(X - C) + C = (X - C) + C = X
Thus:
= zext(X)
---
### Alive2 Validation
The transform was validated using Alive2 with symbolic C.
The constraint that C fits in NarrowBW bits is modeled using llvm.ctlz,
and the precondition X u>= C is enforced via llvm.assume.
Alive2 verifies the transformation under these conditions:

Factor out the handling of coalesced preg COPYs from SystemZMachineScheduler.cpp into MachineScheduler.cpp.
This extends the handling to other types of instructions than COPYs or immediate
loads, such as Load Address and takes care of maintaining the original input
order if both SUs are biased the same way in the same zone.
Another target that uses GenericScheduler can enable this by setting the new
MachineSchedPolicy member BiasPRegsExtra to true (default false). In a derived
scheduling strategy, this could be used either by passing /*BiasPRegsExtra=*/true
to biasPhysReg() (extra instruction detection), or by calling tryBiasPhysRegs()
instead which also preserves the original order if biased the same way.

[lldb][windows] recommend building with Python 3.11 (#191159)
As of https://github.com/llvm/llvm-project/pull/176387 and release 22,
official builds of lldb on Windows use Python 3.11 both on x64 and
arm64.
The Windows lldb build bots use 3.11+ versions of Python:
[lldb-x86_64-win](https://lab.llvm.org/buildbot/#/builders/211) -
`3.12.7`
[lldb-remote-linux-win](https://lab.llvm.org/buildbot/#/builders/197) -
`3.12.7`
[lldb-aarch64-windows](https://lab.llvm.org/buildbot/#/builders/141) -
`3.11.9`
This patch changes the cmake config and documentation to recommend
building lldb on Windows with Python 3.11 or more recent.
In the future, given the reduced number of lldb maintainers on Windows
compared to other platforms, bumping the Python version on Windows would
help reduce the surface area of Python related bugs.

[clang][ssaf] Fix plugin crash on AIX by adding `SUPPORT_PLUGINS` to `clang-ssaf-format` (#192292)
This change fixes a crash when running the `with-plugin.test` lit tests
on AIX. The crash is caused by a missing `-Wl, -brtl` linker flag.
Without this flag, the dynamic linker cannot resolve symbols from the
host executable when loading shared libraries via `dlopen`. So when the
plugin's static initializer runs and tries to register into the
`llvm::Registry` (calling `getRegistryLinkListInstance` defined in the
host via `LLVM_INSTANTIATE_REGISTRY`), the symbol resolves to `null`,
crashing the process.
The fix is to use `SUPPORT_PLUGINS` flag in `add_llvm_executable`, like
other tools in llvm. For AIX, this flag adds `-Wl, -brtl` to enable
runtime linking; for Non-AIX platforms, it sets `LLVM_NO_DEAD_STRIP` to
prevent the linker from stripping symbols that plugins reference at load
time.

[CIR] Add nofpclass for fast-math flags (#191455)
When `-menable-no-infs` or `-menable-no-nans` is set, OGCG adds
`nofpclass(nan inf)` to FP arguments and return values. CIR was missing
this.
Adds the check in `constructFunctionReturnAttributes` and
`constructFunctionArgumentAttributes`, gated on
`hasFloatingRepresentation()` (same condition classic codegen uses in
`canApplyNoFPClass`).
The MLIR LLVM dialect already has `llvm.nofpclass` from #188374, so only
the CIRGen side is needed here.
Test covers float, double, `_Complex double`, and a non-FP control case.

[clang-format] Skip protected data blocks in Verilog (#190695)
A Verilog file can have encrypted stuff (sections 34 and O in the spec).
This patch makes the formatter skip it. Previously the formatter could
mess it up by treating it as ordinary code.
Now the entire block following the `pragma protect` line is treated as a
single token.
The keywords added in this patch only mean special things in the pragma
lines. Thus they are not added to `VerilogExtraKeywords`.
While the files containing the stuff are machine generated, it is a bad
idea for a formatter to break code. For example, one may wish to run the
formatter on an entire project containing both ordinary and encrypted
files. Another use case is formatting the prototypes in files that
contain clear text prototypes in and encrypted implementation.

When `target symbols add` is run, `Symtab::AddSymbol()` can reallocate
the underlying `std::vector<Symbol>` and resize it, invalidating all
existing Symbol* pointers. While `Process::Flush()` clears stale stack
frames, the statusline caches its own `ExecutionContextRef` containing a
`StackID` with a `SymbolContextScope*` (which can be a `Symbol*`). This
cached reference is not cleared by `Process::Flush()`, so the next
statusline redraw accesses a dangling pointer and crashes.
Fix this by adding `Statusline::Flush()` which clears the cached frame,
`Debugger::Flush()` which forwards to it under the statusline mutex, and
calling `Debugger::Flush()` from `Process::Flush()` so that all flush
paths (symbol add, exec, module load) also invalidate the statusline's
stale state.
After this fix, lldb is not crashing anymore, new symbols from a symbol
file are correctly loaded

[OpenASIP] Update the TCE target defs for OpenASIP 2.2 (#176698)
OpenASIP (ex. TCE*) is a special target which has only a stub target
definition in the LLVM side that has resided in LLVM for over 15 years.
I'm the original contributors of this stub.
Due to needing various other patches to LLVM that were not nicely
upstreamable, the upstream TCE target defs have long been unupdated.
However, with the recent changes to the vectorization types etc. I
managed to minimize the required LLVM TCE patch to this one and with
this patch OpenASIP can be (finally!) used without a patched LLVM for
VLIW/TTA customization. RISC-V operation set customization still
requires a patch to polish and upstream (TBD).
This patch:
* Introduces a 64b variant of an OpenASIP target.
* Unifies the datalayouts of the different target variants to make it
compatible with OpenASIP v2.2 and above.
* Updates the OpenCL address space IDs to be compatible with the latest
PoCL backends.
* Implements Triple::computeDataLayout() for completeness.
The patch is very unintrusive and I'd love to backport it in the LLVM 22
release as well.
[*] More info:
https://blog.llvm.org/2010/06/tce-project-co-design-of-application.html
https://openasip.org
The actual backends for the customized processors are generated on the
fly with a backend generator of the OpenASIP project based on a target
definition file and loaded as plugins to the LLVM framework. This
mechanism enables fast "design space exploration" of
application-specific processors designed with the toolset as only a
small part of the compiler has to be regenerated for new design
candidates.

[CUDA] Change __CUDACC__ definition to 1 (#189457)

assuming `__CUDACC__` is not only defined but having a #if-able value.
https://github.com/NVIDIA/nccl/blob/v2.28.3-1/src/include/nccl_device/coop.h#L18
Looking at nvcc invocation, I see that:
```

#define __CUDACC__ 1
```
Changing __CUDACC__ to 1 to match what NVIDIA downstream code

[CIR] Add EH handling for lifetime extended cleanups (#192305)
This adds code to call pushDestroyAndDeferDeactivation from the
pushLifetimeExtendedDestroy function. This was needed to generate the
correct code for lifetime extended cleanups when exceptions are enabled.
An extended version of the cleanup with automatic storage duration is
used as a test case.
To make this work correctly, I had to add a CleanupDeactivationScope to
RunCleanupsScope and force deactivation when forceCleanup is called.
This matches the corresponding code in classic codegen.
I surveyed other places where classic codegen is using
CleanupDeactivationScope and added a MissingFeatures marker in one
location where it was not previously marked. Other places where it was
missing were already marked in this way.

the PCM file buffer into the in-memory cache.

[CIR] Simplify expr with cleanup scopes (#192344)
This change simplifies the level of scopes we build around aggregate
expressions with cleanups and return values involving expressions with
cleanups. This removes unnecessary scopes and lexical scopes that were
created around the expressions and brings the code back into alignment
with the corresponding classic codegen implementation of these handlers.

Key thunkMap on (isec, value, addend) so two call sites with different

also re-organizes the record replay code, moves the whole code to separate
files, and makes it extensible to support other record formats (potentially in
the future). The environment variables for controlling the recording have also
been modified.

not remove their corresponding dominator trees, causing them to be
unnecessarily preserved in memory. This PR addresses the issue by
explicitly calling invalidate within CSE to clean up the dominator trees

Redesign handling of anyAppleOS availability attribute (#190817)
Previously, when processing an anyAppleOS availability attribute, clang
replaced it with an implicit platform-specific attribute (e.g., ios,
macos) inferred for the current target. Only the introduced version of
the original anyAppleOS attribute was preserved (as a field on the
inferred attr). This was insufficient for clients such as Swift that
need access to the full original attribute, including deprecated,
obsoleted, and message fields.
This patch preserves the original anyAppleOS attribute on the decl and
attaches the inferred platform-specific attribute to it as a child via
the new InferredAttr field. Most callers use getEffectiveAttr() to
transparently get the inferred attr when present, preserving existing
behavior. Fix-it hints use the presence of an inferred attr to decide
whether to emit "anyAppleOS" or a platform-specific name in the
@available expression. The one behavioral change is in documentation
XML, where availability info is now emitted for both the anyAppleOS attr
and the inferred platform-specific attr.
When an explicit platform-specific attribute (e.g. ios(introduced=26.0))
conflicts with an anyAppleOS-derived attribute for the same platform,
the explicit attribute wins: the anyAppleOS attribute is erased from the
decl so only the explicit one is used.

[MacroFusion] Early return when insts already clustered (#191710)
This patch adds an early return to `fuseInstructionPair()` when macro
fused instructions are already clustered, either by an earlier fusion or
another clustering like ld/st clustering, removing the assert.
The assert is generally wrong - there are edge cases where an earlier
ld/st clustering (before macro fusion) reached the assert because it
sets `ParentClusterIdx` and fails. For example, ADRP+LOAD/STORE on
AArch64, thought it seems to be a rare case because the addresses are
ususally unkown at compile time.
It doesn't effectively change how fusions are prioritized - early
fusions still win on fusion-fusion conflicts, like before. But it
changes how we resolve the edge case of ld/st-fusion conflicts:
Previously, fusions would effectively override ld/st clustering in this
case, given that we currently limits instruction membership to at most a
single cluster through `ParentClusterIdx`. Macro fusion runs after ld/st
clustering in the pipelines.
Here we inverse the priorities from MacroFusion's perspective and prefer
earlier ld/st clustering. I think they should be generally preferred
over fusions, because they not only save dispatch and execution slots,
but they also should decrease code size. Of course this heuristic can
fail in some cases. If a new clustering algorithm is added, it would
have to inspect ordering and be placed correctly.
I have inspected several internal workloads, and ld/st-fusion conflicts
very rarely appear.

[MC] Fix .prefalign oscillation when body contains a .p2align (#192402)
The intervening FT_Align's padding depends on where this prefalign
lands, so body_size can oscillate across relaxOnce iterations. When a
downstream section reacts (e.g. .debug_line DWARF deltas crossing a
special-opcode boundary), the outer loop never terminates -- originally
reported as a hang with -O1 -g on
https://github.com/llvm/llvm-project/pull/184032#issuecomment-4235991852
```
static int a;
void b() {}
int c() { for (;;) { int d; for (; a;) return 0; } }
void e() { for (;;) ; }
```
X86 sets both the preferred function alignment
and the loop-header alignment to 16 (X86ISelLowering
setPrefLoopAlignment),
so any function containing a small loop whose first BB gets .p2align 4
lands a same-alignment .p2align inside the prefalign body.
Fix: never decrease ComputedAlign across iterations.

[clang] Fix crash in isAtEndOfMacroExpansion at FileID boundary. (#191734)
During error recovery, a synthetic token (whose length is 0) can be
inserted past the end of a FileID, e.g. inserting ")" when a macro-arg
containing a comma should be guarded by parentheses.
When calculating the location after this token, the calculated
`AfterLoc` can point exactly to the start of the next FileID
(`NextLocalOffset`), any source manager operations on the `AfterLoc` are
invalid.
This patch adds a safe guard in `Lexer::isAtEndOfMacroExpansion` to
prevent passing this invalid location to `SourceManager`.

This patch improves recovery when a semicolon is missing after a class
member declarations.
When the parser expects a semicolon but encounters a token that is at
the start of a line and is a valid declaration specifier, it injects a
`;` instead of skipping tokens, this allows us to preserve the
declaration after the missing ";" instead of discarding it.

[BOLT] Update LSDA encoding for x86-64 large code model (#190685)
BOLT hardcoded 4-byte LSDA (exception table) encoding for x86-64. This
is insufficient for large code model binaries where functions in .ltext
sections may be placed at addresses above 2GB, exceeding the range of
DW_EH_PE_udata4/DW_EH_PE_sdata4 encodings.
Detect large code model by checking for .ltext sections
(SHF_X86_64_LARGE) and update LSDAEncoding to use 8-byte pointers:
- Non-PIC: DW_EH_PE_absptr (8-byte absolute)
- PIC: DW_EH_PE_pcrel | DW_EH_PE_sdata8 (8-byte PC-relative)

[TSAN][RISCV] Fix kHiAppMemEnd boundary for riscv64 (#191170)
This resolves TSan execution failures on riscv64 platforms when Address
Space Layout Randomization (ASLR) is disabled. There was an off-by-one
error in `tsan_platform.h` that caused the sanitizer to fail when memory
is mapped at the edge under non-ASLR environments. We fix this by
extending `kHiAppMemEnd` to cover the full allowed memory range:
`MappingRiscv64_39`: `0x3fffffffffull` -> `0x4000000000ull`
`MappingRiscv64_48`: `0x7fffffffffffull` -> `0x800000000000ull`
We also add riscv64 test support to `pie_no_aslr.cpp`

[LV] Add support for absolute difference partial reductions (#188043)
This adds support for partial reductions where the extended operand is a
signed or unsigned absolute difference.
We match the absolute difference as `abs(sub(ext(X), ext(Y)))`, where
`type(X) == type(Y)` and both extends are the same kind (sext/zext).
This is then handled the same as an operand without a binop
(`ext(...)`), as we will transform the operand to
`ext(absolute-difference(A, B))` when we rewrite the reduction chain to
partial reductions.
This is an alternative to #162296.

updating it. Subsequent attempt could go through the "cache miss" part
and the cache would never be used.

I added a basic test setting a couple of options.
I only added the first couple of simple constants (e.g. whose value does
not depend on the architecture). I've left the others for a separate
patch.

Instead of taking this chance, allocate all the pages once and then
split the allocation by changing the permissions of each page. That
ordering we can rely on.
The repeating tag options test is broken due
to #192057 so I've xfailed it.

[mlir][bufferization] Cache areNonConflictingSubsets results in OneShotAnalysis (#189895)
The `areNonConflictingSubsets` check in `hasReadAfterWriteInterference`
can be expensive when called repeatedly for the same (uRead,
uConflictingWrite) pairs during bufferization analysis. This patch
caches the results to avoid redundant computation.
Specifically, this adds:
- A private `nonConflictingSubsetCache` DenseMap on
`OneShotAnalysisState` to memoize subset conflict results.
- A public `areNonConflictingSubsetsCached` method that wraps the
lookup-or-compute pattern, following the same convention as the existing
`findDefinitionsCached`.
- Cache invalidation in `resetCache()`.

[MLIR][Vector] Fix i32 overflow in vector mask lowering for large index bounds (#188782)
When lowering vector masks with `force-32bit-vector-indices=true`, the
mask bound (an `index`-typed value) was cast directly to `i32`. For
values
larger than INT32_MAX (e.g., 2^51), the truncating cast wraps to a small
or negative i32, turning an all-true mask into an all-false one.
Fix both the fixed-size vector path (`buildVectorComparison` in
VectorTransforms.cpp) and the scalable vector path
(`VectorCreateMaskOpConversion` in ConvertVectorToLLVM.cpp) uniformly:
clamp the bound to INT32_MAX via `arith.minsi` in index type before the
cast. For fixed-size vectors `dim` would be a tighter bound (any b >=
dim
already implies all-true), but INT32_MAX is used for consistency across
both paths.
Add a LIT regression test with a 2^51 bound and an integration test that
executes the lowered code to confirm the mask is all-true at runtime.

[LifetimeSafety] Add lifetimebound inference for std::make_unique (#191632)
Enhanced lifetime safety analysis to support `std::make_unique` by
propagating `lifetimebound` attributes from constructor parameters to
`make_unique` parameters.
- Added special handling for `std::make_unique` in
`inferLifetimeBoundAttribute()` to automatically propagate
`lifetimebound` attributes from the constructed type's constructor
parameters to the corresponding `make_unique` parameters
- Extended GSL owner type handling in assignment operations within
`FactsGenerator::VisitCXXOperatorCallExpr()`
`std::make_unique` is a common factory function that forwards arguments
to constructors. Without this enhancement, lifetime safety analysis
couldn't detect when `make_unique` was being used to create objects with
lifetimebound dependencies, leading to missed warnings about potential
dangling references. This change ensures that lifetime safety analysis
works seamlessly with modern C++ idioms using smart pointer factory
functions.
---
**Current Limitation**: Lifetimebound propagation only occurs when the
constructor parameter is a reference type. This restriction avoids
incorrect loan tracking when value types (pointers, view types like
`string_view`) are passed through forwarding references to
`make_unique`. However, this means some legitimate dangling scenarios
involving value-type parameters are not detected. This limitation
presents an opportunity to experiment with `clang::lifetimebound(2)` to
distinguish between parameter categories and enable more precise
tracking for forwarding references and multi-level pointers in general.

[CIR] Implement LValue InitListExpr and FunctionalCastExpr lowering (#192298)
First, this fixes the InitListExpr lowering. This copies the same
implementation from classic-codegen, and adds some tests (this is
otherwise untested in classic codegen?).
Second, while I was writing tests for the above, I accidented into the
FunctionalCastExpr, which just calls emitCastLValue, so this fixes that
as well.

[mlir][vector] Fold vector extract from insert when trailing unit dims (#192109)
Upstreamed from https://github.com/iree-org/iree/pull/23789
Folds vector.extract from vector.insert when the extract position is a
prefix of the insert position and the remaining (un-indexed) dimensions
of the extracted sub-vector are all size 1. In that case the extracted
value is fully determined by the inserted value.
Example:
%ins = vector.insert %s, %v [3, 0] : f32 into vector<16x1xf32>
%ext = vector.extract %ins [3] : vector<1xf32> from vector<16x1xf32>
folds to:
%ext = vector.broadcast %s : f32 to vector<1xf32>

At this moment feature string isn't checked for fitting in such format.
This leads to assertion failure, for example in lldb:
https://github.com/llvm/llvm-project/pull/180901, when features from
user's input don't meet the requirements.
With implementing additional format check we can avoid such problems.

The op supports both spec-defined forms:
- non-block-scaled: 1 input value tensor, `BLOCK_SIZE_1`, 1 output
- block-scaled: data + scale tensor list, non-`BLOCK_SIZE_1`, 2 outputs
Op-specific level checks for ROW_GATHER_BLOCK_SCALED have been deferred
while the TOSA 1.1 draft is still evolving.

Reapply "[VPlan] Extract reverse mask from reverse accesses" (#189930)
Following https://github.com/llvm/llvm-project/pull/146525, separate the
reverse mask from reverse access recipes.
At the same time, remove the unused member variable Reverse from
VPWidenMemoryRecipe.
This will help to reduce redundant reverse mask computations by
VPlan-based common subexpression elimination.
The previous revert was due to an over-aggressive assertion that
incorrectly flagged a reverse load followed by a scatter store as
illegal. This version relaxes the assertion to check the mask only.

[AArch64] Correct comparator in regalloc hints to satisfy strict weak ordering (#192383)
The current comparator will have a strict-weak ordering violation for
the following scenario:
a = GoodReg ((!CSRs.contains(A) || !MRI.def_empty(A) ||
Matrix->isPhysRegUsed(A)) == true) && !Op1Reg
b = BadReg ((!CSRs.contains(A) || !MRI.def_empty(A) ||
Matrix->isPhysRegUsed(A)) == false) && !Op1Reg
c = Op1Reg
Then we would have:
a vs c
A != B && B == Op1Reg && (!CSRs.contains(A) || !MRI.def_empty(A) ||
Matrix->isPhysRegUsed(A)) = true && true && true ->
a < c
a vs b
A != B && B == Op1Reg && (!CSRs.contains(A) || !MRI.def_empty(A) ||
Matrix->isPhysRegUsed(A)) =true && false && false ->
a ~ b
b vs c
A != B && B == Op1Reg && (!CSRs.contains(A) || !MRI.def_empty(A) ||
Matrix->isPhysRegUsed(A)) = true && true && false ->
b ~ c
That will result in a strict-weak ordering violation (a < c && a ~ c),
with the new implementation we define that a < b && a < c.

[Hexagon] Optimize sext + mul pattern to use vmpyh instruction (#190316)
This patch adds TableGen patterns to recognize and optimize the pattern:
(v2i32 (mul (sext v2i16), (sext v2i16)))
And transforms it to use the M2_vmpy2s_s0 instruction which generates
the efficient vmpyh (vector multiply halfwords) instruction.
The transform is guarded by `nsw` because `M2_vmpy2s_s0` performs a
saturating signed multiply (`vmpyh(...):sat`), so the replacement is
only semantics-preserving when signed overflow is undefined in the IR.
Currently, this pattern expands to:
r3:2 = vsxthw(r0) // Sign extend
r1:0 = vsxthw(r1) // Sign extend
r1 = mpyi(r3,r1) // Scalar multiply
r0 = mpyi(r2,r0) // Scalar multiply
With this patch, it generates:
r1:0 = vmpyh(r0,r1):sat // Single vector multiply

[RISCV] Generate landing pad based on cf-protection-branch flag only (#179960)
Previously, the backend generated lpad instructions when the Zicfilp
extension was enabled. This patch changes the behavior to generate lpad
instructions only when the cf-protection-branch module flag is set
(typically from -fcf-protection=branch).
This aligns with the Clang frontend's intent, which has a comment saying
"Always generate Zicfilp lpad insns, Non-zicfilp CPUs would read them as
NOP".
The Zicfilp extension is no longer required for lpad generation - only
the module flag matters. Tests that previously used
-mattr=+experimental-zicfilp to trigger lpad generation now use the
cf-protection-branch module flag.
Additionally, the selection of NonX7 variants for indirect
branches/calls is now based on the cf-protection-branch module flag
instead of the Zicfilp extension. This ensures consistent behavior: when
cf-protection-branch is enabled, X7 is reserved for landing pad labels
and cannot be used for indirect branch/call target addresses.

[CIR][AArch64] Lower NEON vrsra_n intrinsics (#191129)
### Summary
Implement CIR lowering for all intrinsics in
https://arm-software.github.io/acle/neon_intrinsics/advsimd.html#vector-rounding-shift-right-and-accumulate
This PR references the implementation from the ClangIR incubator:
https://github.com/llvm/clangir/blob/main/clang/lib/CIR/CodeGen/CIRGenBuiltinAArch64.cpp#L4854
AArch64 does not provide a dedicated "rounding shift right by immediate"
instruction. Instead, the `SRSHL` / `URSHL` intrinsics take a signed
per-lane shift amount where a negative value means right shift, so an
immediate right shift by `n` is encoded as a signed vector splat of
`-n`. The three infrastructure changes below exist to support this
encoding at the call site:
- extends `emitNeonShiftVector` with a `neg` parameter so the
right-shift-as-negative-left-shift encoding is handled inside the
helper;
- adds `getSignChangedVectorType` (also mirroring the incubator) used to
construct the signed shift-amount vector type for the unsigned path;
- replaces the `errorNYI` in `emitNeonCallToOp`'s `shift == j` branch
with an actual call to `emitNeonShiftVector`.
Tests: new CHECK lines in clang/test/CodeGen/AArch64/neon/intrinsics.c
under section 2.1.3.2.4.
Part of #185382.

[X86] Use unsigned comparison for stack clash probing loop (#192355)
The stack clash probing loop generated in `EmitLoweredProbedAlloca` used
a signed comparison (`X86::COND_GE`) to determine when the allocation
target had been reached.
In 32-bit mode, memory addresses above `0x80000000` have the sign bit
set. If the stack pointer lands in this region, treating the addresses
as signed integers causes the comparison logic to fail. This leads to
incorrect loop execution, resulting in an infinite loop and a crash
(segmentation fault) when setting up custom stacks for pthreads mapped
above `0x80000000` in a 32b process.
This patch changes the condition code to `X86::COND_AE` (Above or
Equal), which generates an unsigned comparison. This ensures that
addresses are treated correctly as unsigned quantities on all targets.
On 64-bit systems, this change has no practical effect on valid
user-space addresses because they do not use the sign bit (being
restricted to the lower half of the address space). However, using
unsigned comparison is the correct behavior for pointer arithmetic and
bounds checks.

[MCP][NFC] Opinionated refactoring (#186239)
There are a few minor inconsistencies across the pass which I found mildly distracting:
* The use of `Def`/`Dest`/`Dst` to refer to the same thing
* Inconsistent declaration order of `Dst`/`Src` vs `Src`/`Dst`
* Lots of `->getReg()->asMCReg()`, and uses of `Register` when the pass
is always running after RA anyway.
* Some places explicitly `assert(isCopyInstr)` while others just deref
the `optional`.
Standardize on `Dst`/`Src` to match the metaphor and ordering of
`DestSourcePair`.
Assume `std::optional::operator*` will assert in any reasonable
implementation, even though this may technically be undefined behavior.
When asserts are disabled it would be anyway.
The refactor uses structured bindings for a couple reasons:
* Naturally enforces consistent order of `Dst`-then-`Src`
* Requires the use of `auto`, which ensures the declaration is not
implicitly converting from `MCRegister` back to `Register`.
In both cases the explicitness of the name `getDstSrcMCRegs` hopefully
makes the meaning at the callsite clear (`Dst, Src = DstSrc`, and
explicitly mentioning `MCReg`).

The `SPIRVStripConvergenceIntrinsic` pass was written as a spirv pass as
it is the currently the only target that emits convergence tokens during
codegen. There is nothing target specific to the pass, and, we plan to
emit convergence tokens when targeting DirectX (and all targets in
general), so move the pass to a common place.
The previous pass used temporary `Undef`s, as part of moving the pass we
can simply reverse the traverse order to remove the use of `Undef` as it
is deprecated.
Enables the pass for targeting DirectX and is a pre-req for:

[SLP] Normalize copyable operand order via majority voting
When building operands for entries with copyable elements, non-copyable
lanes of commutative ops may have inconsistent operand order (e.g. some
lanes have load,add while others have add,load). This prevents
VLOperands::reorder() from grouping consecutive loads on one side,
degrading downstream vectorization.
Add majority-voting normalization during buildOperands: track the
(ValueID, ValueID) pair frequency across non-copyable lanes and swap
any lane whose operand types are the exact inverse of the most common
pattern. This makes operand order consistent, enabling better load
grouping.
This is part 1 of #189181.

Fix InlineAsmOp parser/printer roundtrip for cir.asm and avoid null

- Parse attr-dict before optional result arrow to match print order.
- Use non-null sentinel attributes for non-maybe_memory operands and
check UnitAttr explicitly.
- Keep lowering semantics by treating only UnitAttr as maybe_memory
marker.
- Update inline-asm CIR IR test to run with --verify-roundtrip and add
an attr+result coverage case.

[CIR] Fix FlattenCFG pattern rewriter contract violations (#192359)
Fix patterns in CIRFlattenCFGPass that modify IR but return failure(),
violating the MLIR greedy pattern rewriter contract. The contract
requires that if a pattern modifies IR, it must return success().
- CIRCleanupScopeOpFlattening: always return success() since IR is
modified (blocks split, regions inlined) before error paths
- Ternary op flattening: return success() instead of falling through
after emitError, since splitBlock/createBlock already modified IR
- Use rewriter.moveOpBefore() instead of direct defOp->moveBefore() to
properly notify the rewriter of IR mutations
Found by MLIR_ENABLE_EXPENSIVE_PATTERN_API_CHECKS=ON.
Test: flatten-cleanup-scope-nyi.cir (a silly one since it's testing an
error, but point still valid)

Presumably targets only insert frame instructions which are significant,
and there may be effects MCP doesn't model. Similar to reserved
registers this
is probably overly conservative, but as this causes no codegen change in
any lit test I think it is benign.
The motivation is just to clean up #183149 for AMDGPU, as we can spill
to physical registers, and currently have to spill the EXEC mask purely
to enable debug-info.

[flang] Inline scalar-to-scalar TRANSFER for same-size trivial types (#191589)
Inline the TRANSFER intrinsic for scalar-to-scalar cases where the
result is a trivial type (integer, real, etc.) and source and result
have the same storage size. Instead of calling _FortranATransfer, the
lowering now emits a fir.convert on the source address followed by a
fir.load, effectively performing a reinterpret cast.

[Clang] Add multilib support for GPU targets (#192285)
Summary:
This PR uses the new, generic multilib support added in
https://github.com/llvm/llvm-project/pull/188584
to also function for GPU targets. This will allow toolchains to easy
provide variants of these GPU libraries (for debug or asan). In
practice, this will look something like this:
```console
-DRUNTIMES_amdgcn-amd-amdhsa+debug_CMAKE_BUILD_TYPE=Debug \
-DRUNTIMES_amdgcn-amd-amdhsa+debug_LIBOMPTARGET_ENABLE_DEBUG=ON \
-DRUNTIMES_amdgcn-amd-amdhsa+debug_LLVM_ENABLE_RUNTIMES=openmp \
-DLLVM_RUNTIME_MULTILIBS=debug \
-DLLVM_RUNTIME_MULTILIB_debug_TARGETS="amdgcn-amd-amdhsa" \
```
This will then install it into the tree like this:
```
<install>/lib/amdgcn-amd-amdhsa/debug/libompdevice.a
```
The user can then activate this like the following (assuming they have a
multilib.yaml in the library directory):
```
clang input.c -fopenmp --offload-arch=gfx942 -fmultilib-flag=debug
```

[RISCV] Use unsigned comparison for stack clash probing loop (#192485)
The stack clash probing loop generated in `emitDynamicProbedAlloc` used
a signed comparison (`RISCV::COND_BLT`) to determine when the allocation
target had been reached.
In 32-bit mode, memory addresses above `0x80000000` have the sign bit
set. If the stack pointer lands in this region, treating the addresses
as signed integers causes the comparison logic to fail.
This patch changes the condition code to `RISCV::COND_BLTU` (Branch if
Less Than Unsigned), which generates an unsigned comparison. This
ensures that addresses are treated correctly as unsigned quantities on
all targets.
On 64-bit systems, this change has no practical effect on valid
user-space addresses because they do not use the sign bit (being
restricted to the lower half of the address space). However, using
unsigned comparison is the correct behavior for pointer arithmetic and
bounds checks.

`ACCImplicitDeclare` to do so by using new API
`wireHoistedValueThroughIns` which handles the value wiring after

[BOLT][Passes] switch remaining Instrumentation containers to ADT. (#192525)
Follow-up to #192289. Swap the remaining `std::unordered_set`/
`std::unordered_map` containers in `Instrumentation.cpp` for `DenseSet`/
`DenseMap`: the `BBToSkip` param and `Visited` local in
`hasAArch64ExclusiveMemop`, and `BBToSkip`, `BBToID`, `VisitedSet` in
`instrumentFunction`. Drop the now-unused `<unordered_set>` include.
The swap removes per-element heap allocations on the hot path, stops
inserting empty buckets on probes where a miss is possible, and replaces
hashed-bucket traversal over node-based storage with lookups over inline
`DenseMap` storage. `BBToID` reads keep `operator[]` since the map is
pre-populated for every basic block of the function, so no
default-construct path is ever taken. NFC.
Measured on `llvm-bolt -instrument` against a relocations-linked
clang-23: -1.3% instrumentation-pass wall time, peak RSS unchanged
(dominated by instrumentation output size).

Added:
* src/ucontext/getcontext.h and setcontext.h
* src/ucontext/x86_64/getcontext.cpp and setcontext.cpp
* Hermetic integration test for register preservation.
* Unit tests for basic functionality and signal mask preservation.
Updated entrypoints for x86_64 Linux.

I also considered other approaches such as modifying the
`PrintingPolicy` in the current `AstContext`, but that might cause
unexpected changes.
Add two tests:
1. To ast-printer-lambda to ensure `--print-ast` works the same.
2. Ensure lambda body is not printed for constexpr diagnostics.

[BPF] Add exception handling support with .bpf_cleanup section (#192164)
Add support for invoke/landingpad/resume instructions in the BPF backend
so that Rust programs compiled with panic=unwind can run cleanup code
(Drop implementations) when bpf_throw fires.
Changes:
1. BPFISelLowering: Define exception pointer and selector registers
(both R0) so SelectionDAG can lower landingpad instructions.
2. BPFAsmPrinter::emitFunctionBodyEnd: Emit a .bpf_cleanup section with
a flat table of (begin, end, landing_pad) triples using
R_BPF_64_NODYLD32 relocations.
The .bpf_cleanup section layout (12 bytes per entry):
u32 begin // start of the invoke region
u32 end // end of the invoke region
u32 landing_pad // address of the cleanup block
The invoke region [begin, end) includes argument setup instructions
before the call. The runtime checks begin <= PC < end to find the
matching landing pad.
Landing pad blocks survive optimization because invoke maintains CFG
edges to them throughout codegen, same as every other backend. The
standard .gcc_except_table and .eh_frame are also emitted by the
existing DwarfCFIException handler; libbpf will ignore them.
In runtime:
- bpf_throw() is called (from panic handler)
- Kernel walks the BPF call stack with arch_bpf_stack_walk()
- For each frame, look up current PC in .bpf_cleanup table
- If match found: redirect execution to the cleanup function . cleanup
function runs Drop impls (bpf_free, rcu_read_unlock, etc.) . calls
_Unwind_Resume() which is patched to just 'ret' by the verifier .
bpf_throw() pops frame goes to next
- If no match: go to next frame

[mlir] transform dialect; add pre/post-condition type (#191813)
Add a transform dialect type denoting additional invariants on payload
IR usable for pre/post-conditions of a transformation. The invariants
are defined as a list of attributes in the type parameter, where the
attribute implements the interface for invariant-checking. This allows
clients to factor out, explicify and deduplicate precondition
verification logic.
This required adding support for Transform dialect extensions injecting
attributes into the dialects similarly to how they already do this for
operations and types.

[LoopBoundSplit] Fix edge connections during transformation (#192106)
Fixed #190672.
The issue is caused by invalid intermediate IR when `getSCEV()` is
called during transformation: the exiting block of `pre-loop` did not
re-connect to preheader of the `post-loop`, causing `LI.verify()`
unable to correctly recompute another LoopInfo for verification.
To fix, reconnect the edge earlier before calling `getSCEV()`.
Also moved the DT updates to more appropriate places right after IR
control flow has changed. and added a few LI and DT verifications to
improve robustness of the pass.

[lldb] Scaffolding for synthetic variable support. (#181500)
This patch handles most of the scaffolding for synthetic variable support that isn't directly tied to functional changes. This patch will be used by one following patch that actually modifies the lldb_private::StackFrame API to allow us to fetch synthetic variables.
There were a couple important/interesting decisions made in this patch that should be noted:
- Any value type may be synthetic, which is why it's a mask applied over the top of another value type.
- When printing frame variables with `fr v`, default to showing synthetic variables.
This new value type mask makes some of the ValueType handling more interesting, but since nothing generates objects with this mask until the next patch, we can land the concept in this patch in some amount of isolation.

They were relying on the host value not being seen on the device, but
the value being matched was small enough for the probability of a
successful match against garbage data relatively high.
Now we just rely on the LIBOMPTARGET_DEBUG logs to ensure there wasn't
any transfer.

This patch also expose a requeue API that returns ENOSYS on unsupported

FIFO style condvar similar to musl.
Additional cleanup is done to change raw syscall return value to
`ErrorOr<int>`.
