[flang] Fix abort on invalid -fdo-concurrent-to-openmp value. (#193929)
We observed that following command can cause an assertion fail
`flang -fopenmp -fdo-concurrent-to-openmp=devic,e` <file>
It happened because `parseDoConcurrentMapping` reported an error but
still called `val.value()` on failure, tripping std::optional
assertions.
The fix is to return false on error and wire return into
`createFromArgs`.

CodeGen: Fix double counting bundles in inst size verification (#191460)
The AMDGPU implementation handles bundles by summing the
member instructions. This was starting with the size of the
bundle instruction, then re-adding all of the same instructions.
This loop is over the iterator, not instr_iterator, so it should
not be looking through the bundled instructions. Most of the other
uses of getInstSizeInBytes are also on the iterator, not the
instr_iterator so the convention seems to be targets need to handle
BUNDLE correctly themselves.

[ThinLTO] Reduce the number of renaming due to promotions in distribu… (#188074)
…ted mode
For thin-lto, the pull request [1] reduced the number of renaming due to
promotions in process mode. This has been used in linux kernel ([2]) as
it helps kernel live patching a lot.
Recently, I found Rong Xu has added thin-lto distributed mode support in
linux kenrel ([3]) and it is likely to be merged in kernel as well. So
it would be a good idea for llvm to support reducing the number of
renaming in distributed mode too.
To implement this, in function gatherImportedSummariesForModule(),
import functions into summaries if those functions does not need rename.
This will ensure that imported functions have the same name as in there
original module.

This PR adds lowering for the missing conversion intrinsics with an
immediate argument (identified by `_n_` in the intrinsic name), namely
the `vcvts_n_` and `vcvtd_n_` variants.
It also moves the corresponding tests from:

[SLP] Skip FMulAdd conversion for alt-shuffle FAdd/FSub nodes (#193960)
isAddSubLikeOp() admits alt-shuffle nodes that mix FAdd and FSub, so
transformNodes() was marking them with CombinedOp = FMulAdd. The cost
model then priced the node as a single llvm.fmuladd vector intrinsic,
but emission for an alt shuffle still goes through the ShuffleVector
path and produces fmul + fadd + fsub + shufflevector, which the backend
cannot fuse into a single fmuladd. The resulting under-count made SLP
choose the vector form over the scalar form even when the scalar form
lowers to real FMAs (e.g. fmadd + fmsub on AArch64).

[DirectX] Denote `dx.resource.getpointer` with `IntrInaccessibleMemOnly` and `IntrReadMem` (#193593)
`IntrConvergent` was originally added to `dx.resource.getpointer` to
prevent optimization passes (`SimplifyCFG`, `GVN`) from sinking the
intrinsic out of control flow branches, which would create phi nodes on
the returned pointer.
Using `IntrInaccessibleMemOnly` and `IntrReadMem` semantics still
prevent passes from merging or sinking identical calls across branches.
However, this allows the call to be moved within a single control flow
path.
Updates relevant tests and adds a new test to demonstrate a now legal
potential optimization.
This was discovered when
https://github.com/llvm/llvm-project/pull/188792 caused the following
failure:
https://github.com/llvm/llvm-project/actions/runs/24577221310/job/71865579618.
When emitting convergence control tokens, each resource access is then a
user of the convergence control tokens, which makes it's use more
unnecessarily restrictive for optimizations and in this case would
prevent a loop unroll from taking place.

[CIR] Tolerate identical source and destination in cir.copy (#193852)
The SIBsim4 test in the llvm-test-suite MultiSource tests has code that
initializes a structure with itself. This was triggering a CIR
verifcation error because we were checking for source and destination
addresses matching. Since Clang allows this, this change is updating the
cir.copy operation to allow it.

[flang] [flang-rt] Implement AT edit descriptor for Fortran 202X with appropriate handling and tests (#189157)
This PR is to add AT edit descriptor, a new feature of Fortran 2023, 5.1
US 10.
AT is like A (character output) but trims trailing blanks before
emitting the string. AT is functionally the same as TRIM intrinsic.
AT is treated as a variant of A during parse. The trimming of the
trailing spaces are implemented the same as TRIM(). There exists a
method, LenTrim, that can be used to do the trimming. However it's local
to a different .cpp file, character.cpp. And the code is so simple that
no need to make extra effort to use LenTrim.
AT is output only and do not accept width.
This PR will fix #181379.

[llvm] Introduce TargetInfo (#190730)
This PR introduces ABIInfo and TargetCodeGenInfo, the abstract ABI
lowering layer for the LLVM ABI library introduced in #158329.
This is a direct parallel to clang::ABIInfo and
clang::TargetCodeGenInfo, but operating entirely on the llvm::abi type
system rather than Clang's AST, keeping ABI logic independent of the
frontend. It is a prerequisite for implementing the target specific
lowering passes that lower FunctionInfo to LLVM IR calling conventions.

[CIR] Update uses of no-prototype GetGlobalOp (#193868)
When a no-prototype function is replaced by a proper definition, we
update uses of the previous function, mostly cir::GetGlobalOp
operations. If the result of the GetGlobalOp was being used in a store,
this was leading to verifier errors because the type being stored no
longer matched the expected type. This change fixes that by introducing
a bitcast when the GetGlobalOp is updated. It also introduces a new cast
folder to eliminate cast chains that are circular after this new bitcast
is inserted.

[DirectX] Resolve unreachable default branches in switch statements (#193592)
Add a legalization to resolve unreachable default branches in switch
statements. These are introduced when the
`CorrelatedValuePropagationPass` proves all cases of a switch are
covered, leaving the default as an unreachable block.
The default destination is replaced with either the common successor
block or the first switch case destination.
This was discovered from the following case:
https://godbolt.org/z/W7zE1GMT6, where we can see that the unrolling of
the outer loop is not successful and the switch statement with an
`unreachable` branch remains.

[compiler-rt] Improve ubsan-minimal runtime for GPU use (#193597)
Summary:
GPUs are resource constrained, and we don't want to incur too much
overhead for using the runtime over a trap version. Unlike the other
targets, we have cheap `printf` on account of all the complexity being
done on the host, so we use that directly instead of custom formatting.
Additionally, we split the main function out into a helper function.
Listing it as `[cold]` prevents spurious inlining that massively bloated
register costs (this is an error reporting mechanism so hopefully that's
not controversial).
In practice for some basic tests, This cuts the register usage by more
than half and the stack size is no longer dynamically sized. The only
stack I saw was for the PC relative checks. This could be lowered
further with more intelligent PC caching, but this is a good, minimally
invasive, start.

[lldb] Allow forks to occur in expression evaluation (#184815)
@jimingham You had suggested to @clayborg that we should call DidFork(),
DidVFork() and DidVForkDone() after a corresponding stop in expression
evaluation. Those functions require parameters that are private to the
specific child StopInfo class. I went with reusing the existing
StopInfo::PerformAction() virtual function, rather than create a new one
just for this purpose.

[CIR] Add `__attribute__((annotate(...)))` support (#193329)
Implement end-to-end (Dialect, CIRGen, Lowering) support for
__attribute__((annotate(...))) on functions and global variables.
Dialect:
- cir::AnnotationAttr (#cir.annotation<name = "...", args = [...]>).
- $annotations on cir.func and cir.global (ArrayAttr of AnnotationAttr).
FuncOp gets a custom parser/printer entry; for GlobalOp it's tacked onto
the assemblyFormat.
CIRGen:
- Annotations are attached as deferred entries in CIRGenModule and
flushed at end-of-TU so the most up-to-date ValueDecl wins (decl
annotations + def annotations both stick).
- emitAnnotationArgs uniques arg ArrayAttrs via FoldingSetNodeID so two
functions with identical args share one ArrayAttr (and one .args
constant in LLVM lowering).
- addGlobalAnnotations supports both GlobalOp and FuncOp paths,
including function-local statics (emitStaticVarDecl).
Lowering:
- CXXABILowering treats AnnotationAttr as legal (no ABI conversion).
- Direct-to-LLVM lowering filters the annotations attribute off
cir.func, then collects (sym_name, AnnotationAttr, loc) tuples
pre-conversion and post-conversion emits @llvm.global.annotations plus
the supporting strings/args constants in section "llvm.metadata" —
bit-for-bit comparable to OGCG. String constants and per-arg structs are
deduplicated; identical args ArrayAttrs share one .args global (an
improvement over OGCG's per-site copies).

[CIR] Fix remaining (part 2) FlattenCFG rewriter contract violations (#192503)
Fix all 17 remaining MLIR expensive pattern check violations in
CIRFlattenCFGPass. Found by MLIR_ENABLE_EXPENSIVE_PATTERN_API_CHECKS=ON.
Fingerprint violations (patterns modifying IR without notifying
rewriter):
- Use rewriter.replaceAllUsesWith() instead of direct
replaceAllUsesWith() in replaceCallWithTryCall (tests: invoke-attrs.cpp,
try-catch.cpp, try-catch-all-with-cleanup.cpp)
- Use rewriter.modifyOpInPlace() for removeCleanupAttr() in TryOp
flattening (tests: flatten-try-op.cir, flatten-cleanup-scope-eh.cir,
flatten-throwing-in-cleanup.cir)
IR verification failures (invalid intermediate IR after pattern
application):
- Expand nested op checks in Switch, Loop, CleanupScope, and TryOp
flattening to include all structured CIR ops (ScopeOp, IfOp, TernaryOp,
etc.), not just CleanupScopeOp. Break/continue/return inside nested
structured ops creates invalid cross-region branches when the enclosing
op hasn't been flattened yet (tests: switch.cir, loop.cpp,
cleanup-scope-return-in-loop.cpp, partial-array-cleanup.cpp, switch.cpp,
typeid.cpp, flatten-cleanup-scope-simple.cir,
flatten-cleanup-scope-multi-exit.cir)
- Relax CIR_ResumeOp ParentOneOf to include all structured ops, since
cir.resume can temporarily appear inside them during flattening (test:
new-delete-deactivation.cpp). Feels weird to do that, but extended
documentation to account for.
- Change loop region constraints from SizedRegion<1> to
MinSizedRegion<1> for cond/step regions, since cleanup scope flattening
inside these regions may create multiple blocks (test:
loop-cond-cleanup.cpp)

[mlir] Add analysis filter in dataflow solver (#192998)
Adds an optional filtering control function to the dataflow solver's
initializeAndRun callback, which controls which analyses will be
initialized when running the solver. This makes it possible to reuse
existing dataflow solver instances that have already run to a fixpoint
without re-initializing all of the analyses that have already converged.
A new analysis and test pass is also added, which illustrates how the
filtering can be useful to run a staged analysis, which would not have
been possible before. The example analysis, called `BarAnalysis`,
depends on the converged state of the `FooAnalysis`. The Bar analysis is
a forward analysis that tracks, for each program point, whether any of
the preceding program points hold a `foo_state` that is divisible by 4.
In the example test, the control flow graph looks like the following:
```
entry-block
/ \
bb0 bb2
\ /
bb1
```
The `foo_state` of `bb1` depends on the `foo_state` of `bb0` and `bb2`.
If the solver goes through `bb0->bb1` before `bb2->bb1`, then there is
an intermediate stage in the analyses where the state of `bb1` could be
divisible by 4, even though the final state of `bb1` will not be
divisible by 4 in the converged state. If the `BarAnalysis` runs on
`bb1` in this intermediate state, then it will get stuck with the
"divisible by 4" state, and the analysis will not yield the desired
results.
This PR ensures that the `BarAnalysis` will see the correct state
`foo_state`, because the `FooAnalysis` will fully run to a fixpoint
before the `BarAnalysis` is loaded, initialized, and run.
The Foo and Bar analyses are just trivial examples, but this pattern is
useful when there are analyses that can be made more effective by using
complementary analyses like integer range/divisibility analyses.
**Note for integration:**
DataFlowSolver::load now stores the concrete analysis TypeID, exposed
via DataFlowAnalysis::getTypeID(). Downstream DataFlowAnalysis
subclasses defined in anonymous namespaces must add
MLIR_DEFINE_EXPLICIT_INTERNAL_INLINE_TYPE_ID(ClassName) to their class
body.

[LoopVectorize] Don't replace widen with replicate for ExtractValueInst (#193404)
VPWidenRecipe with an underlying ExtractValueInst stores the
ExtractValue's indices() as part of the recipe's "operands",
necessitating special handling (see VPRecipeBuilder::tryToWiden() and
VPWidenRecipe::execute()). This makes it incompatible with conversion to
VPReplicateRecipe, because VPReplicateRecipe's scalarizeInstruction()
may attempt to set each operand of the cloned ExtractValueInst, but the
indices cannot be set via setOperand().
This patch works around the issue by preventing the conversion of
ExtractValueInst-based VPWidenRecipe to VPReplicateRecipe.

This PR adopts the following strategy for emitting optimization remarks
in loop unrolling:
- Emit passing optimization remarks any time we decide to unroll.
- Only emit missed optimization remarks if the user explicitly requested
unrolling and we aren't able to honor their request.
- Only emit passing or missed optimization remarks when we're certain
that unrolling will succeed or fail.
- In lieu of emitting more informative passing/failing optimization
remarks when unrolling may still fail/pass, emit analysis optimization
remarks so users can understand the reason as to why unrolling may have
failed on that loop.

[lldb][Darwin] debugserver expedite new binary info, lldb use (#192754)
When lldb stops at the "new binaries loaded" internal breakpoint, it
must read the list of addresses of the new binaries out of process
memory, then send a jGetLoadedDynamicLibrariesInfos packet to
debugserver to get the filepath, uuid, and addresses of where all the
segments are loaded in memory.
It's possible for debugserver to find the "new binaries loaded" function
address in the inferior itself, recognize when it has stopped at a
breakpoint there, and expedite some/all of the information lldb is going
to ask for in the stop info packet that we send to lldb. This will make
big improvements to a large-batch-of-binaries loaded stop event, but
also focuses even more on the single-binary-loaded `dlopen()` use case,
which can be quite expensive when many binaries are loaded one by one.
This PR reduces the packet traffic for a new binary load notifications
by
1. When debugserver sees a thread that has hit a breakpoint, and the pc
matches the new-binaries-loaded function address, reads the list of
binaries that have been newly added and includes them in the stop info
packet (or the jThreadsInfo packet) in the `added-binaries` key. The
value is a list (array) of binary addresses.
2. If the number of binaries is small (today: one), debugserver may
collect the full information that jGetLoadedDynamicLibrariesInfos would
send back about it, and also expedite that in the stop info packet (or
jThreadsInfo) in the `detailed-binaries-info` key. This is a JSON
string, and the stop info packet is a semicolon separated series of
key-values, so it must be asciihex encoded, just like the `jstopinfo`
key. In the jThreadsInfo packet, the JSON for the binary information is
included in the response as-is as the value-dictionary.
3. If the remote stub doesn't provide these new keys, lldb will use the
same process as before. However, in
DynamicLoaderMacOS::NotifyBreakpointHit I was reading the load addresses
out of memory individually, with each binary having a 24-byte entry.
lldb's memory cache meant we read 512 bytes per 8-byte read, but when
1000 binaries were being loaded at process launch time, that was 24,000
bytes of VM that we would read in 512 byte batches. This patch changes
that to read the entire VM range that we will be accessing in one large
memory read (as large as the remote gdb RSP stub will support),
dramatically reducing packet traffic in that case.
4. debugserver needs to read the "new binaries loaded" function pointer
out of the "dyld_all_image_infos" structure in the inferior, and it is a
signed function pointer on arm64e processes, so debugserver needs to
strip off the signing bits before comparing the pc. I hoisted the strip
function out of DNBArchImplArm64 into DNBFixAddress(), and the only
complicated bit here is in DNBProcessAddrSize(), when an arm64e
debugserver is debugging an arm64_32 process on a watch. It's not a
common combination (mostly we will have arm64e debugservers debugging
arm64 processes, or arm64_32 debugservers debuggging arm64_32 processe),
but it is supported.
5. A very minor enhancement, I have debugserver now include a new key,
`sizeof_mh_and_loadcmds` in the full binary information that
jGetLoadedDynamicLibrariesInfos returns. When lldb needs to read a
binary out of memory, it needs to read the Mach-O header & load
commands, and it doesn't know the full size of that, so we end up doing
one read of the Mach-O header, then the header + load commands. I'm not
using this information in lldb yet, but I would like to, to improve
that.
At an implementation detail level, ProcessGDBRemote collects these two
new data from the stop packet / jThreadsInfo, and passes them to the
method that creates a new ThreadGDBRemote. I added two methods to the
Thread base class to retrieve the information. DynamicLoaderMacOS will
try to read the data from the thread that hit the "new binaries loaded"
breakpoint, and if the number of entries matches the number expected by
the register value, uses them. Else it falls back to fetching them the
traditional way. On an old debugserver that doesn't support these new
expedited fields, DynamicLoaderMacOS will get back a zero-length of
binary addresses and a null StructuredData dictionary for the detailed
image information, and behave as it always does. I tested this patch
with both the debugserver changes, and without.
Testing is clearly the big questionmark here - I added none. While
writing these patches, I had some bugs and the lldb testsuite on macOS
was very good at finding them, simply with our normal process launching
and dlopen'ing in our existing API tests. I could imagine a test that
would capture the packet log and try to ensure that the expedited
information is being used by lldb and we are not re-fetching the
information, though.

[dsymutil] Handle DW_OP_GNU_push_tls_address in markEverythingAsKept (#193870)
markEverythingAsKept() only checked for DW_OP_form_tls_address when
deciding whether a TLS variable should be added to accelerator tables,
missing the DW_OP_GNU_push_tls_address extension. This caused TLS
variables using the GNU form to be absent from .apple_names when linking
in update mode (-u) or when processing Clang modules.
The same bug was previously fixed in getVariableRelocAdjustment()
(f9f92f13f62a) but was missed here.

[AMDGPU] Correct gfx950 smfmac sparse index verifier (#193541)
Originally, the smfmac verifier expects for the sparse indices, which
describe which the positions of the non-zero elements per lane, the
following:
```
8 bit source -> require vector<2xi16>, ABID range [0, 1]
16 bit source -> require vector<4xi8>, ABID range [0, 3]
```
which is correct for CDNA3 and what was stated in the CDNA4 ISA
description as well. However, because the CDNA4 variants have double K
of the CDNA3 variants, meaning e.g, for 16 bit variants, each lane
carries 8 non-zero values rather than 4, we need 16 bit sparse indices
to express the full range of non-zero elements. This is in line with the
layout tables presented in the CDNA4 ISA.
Direct comparison for 16 bit elements:
On gfx942; we can select from one of four 8-bit sets of sparse indices
with ABID. Each set represents the location of four non-zero values per
8 following 4:2 structured sparsity. For example:
```
a0 a1 0 0 a3 a4 0 0 | a5 a6 0 0 0 0 a7 a8 | a9 0 0 a10 0 a11 0 a12 | 0 a13 0 a14 0 a15 0
```
On gfx950; because each lane carries 8 non-zero values; we can only
specify the full range of 8 non-zero values per 16 from one of two
16-bit sets. For example:
```
a0 a1 0 0 a3 a4 0 0 a5 a6 0 0 0 0 a7 a8 | a9 0 0 a10 0 a11 0 a12 0 a13 0 a14 0 a15 0
```
Similarly, for 8 bit variants on gfx950, we would need the full 32 bits
to describe the full range of the locations for the 16 non-zero 8 bit
elements. In this case, there is no option to select from different sets
of indices.
The issue arises in downstream use cases if we want to use use a set of
sparse indices targeting gfx950; because we are unable to specify the
full range of the non-zero values at the moment, we will get numerical
issues.

[llvm] Implement the BPF ABI (#194031)
Implements BPFTargetInfo, the first target-specific ABI lowering for the

BPFTargetInfo mirrors the BPF ABI rules currently encoded in
`clang::BPFABIInfo` (clang/lib/CodeGen/Targets/BPF.cpp), but operates
entirely on `llvm::abi` types, keeping the logic frontend-independent:
- Empty aggregates and void returns are ignored
- Aggregates ≤64 bits are coerced to an aligned integer type
- Aggregates 65–128 bits are coerced to [2 x i64]
- Aggregates >128 bits and oversized _BitInt types are passed/returned
indirectly
- Promotable integers are sign/zero extended
- All aggregate returns are indirect
Also adds the `createBPFTargetInfo` factory function declaration to
TargetInfo.h.

Adds LFI rewrites for control flow instructions (indirect branches and

guaranteed to hold a sandbox address. Modifications to `x30` must guard
`x30` afterwards, to uphold the invariant that `x30` always holds a
sandbox address. As a result, bare return instructions can be used
without any additional rewrites.

[dsymutil] Report error when section offsets exceed DWARF32 limit (#193867)
When linking very large binaries, debug section offsets can exceed the 4
GB DWARF32 limit. Previously this caused an assertion in
MCStreamer::emitIntValue when trying to emit an overflowing
DW_FORM_sec_offset value.
Detect the overflow at the point where section offsets are patched in
DWARFStreamer (for .debug_ranges, .debug_rnglists, .debug_loc,
.debug_loclists) and in DWARFLinker (for .debug_line and .debug_addr).

[llvm-profgen] Add support for ETM trace decoding (#191584)
This patch introduces ETMReader to llvm-profgen,
enabling the reconstruction of execution profiles from ETM formatted
trace data.
- Integrate OpenCSD (CoreSight Decoding Library) as an optional
dependency via the LLVM_ENABLE_OPENCSD flag.
- Implement ETMTraceDecoder in ProfileData to interface with OpenCSD.
- Implement ETMReader, which uses hardware configuration and ELF memory
mapping to decode instruction traces.
- Add the --etm command-line option to specify raw trace inputs.
- Add the --target-triple command-line option to override the target
architecture for the binary.
The implementation targets microcontroller-class (Cortex-M) devices
based on the binary's target triple.

[RISCV] Expand fcanonicalize on vector types (#193842)
This change does a couple of related things:
1) It changes the default expansion strategy for scalable
vectors for fcanonicalize. This switches us from
emitting a loop (directly parallel to unrolling)
to using the already available fmul expansion.
2) Mark RISC-V legal scalable vector types as Expand
to leverage the previous item.
3) Wrap fixed vector types in their corresponding
scalable types to avoid unrolling.
The net effect is to improve the lowering for fixed vector cases and to
no longer crash for the scalable ones. We were crashing because the
scalable cases were marked Legal, not Expand. We could have just fixed that, but doing everyone at once seemed like a good investment.
Note that we can also choose to follow Aarch64 and consider a vfmin
based lowering. I left that until later thought it is worthwhile noting
that's what we do for scalar code.

[lldb] Handle partial memory region coverage in IRMemoryMap::FindSpace (#194001)
FindSpace walks process memory regions to find addresses that won't
collide with the inferior's real memory. This is necessary even for
host-only allocations because the IR Interpreter works entirely in
inferior virtual addresses. IRMemoryMap remaps those addresses to read
from host memory instead of inferior memory, so overlapping ranges would
silently read the wrong data.
For WebAssembly, GetMemoryRegionInfo succeeds for the first region
(linear memory) but fails for addresses beyond it. The previous fix
(#193124) skipped the memory region walk entirely when `CanJIT()` is
false. However, as Jason points out, that removes the
collision-avoidance mechanism and risks overlapping with real inferior
memory.
Instead, handle the GetMemoryRegionInfo failure gracefully. If the
target can't describe memory beyond a certain point, treat the remaining
address space as unmapped and use it for the allocation. This preserves
the collision avoidance while avoiding the lldbassert.

[compiler-rt][WebAssembly] Use an int as CMP_RESULT (#194093)
LLVM uses an i32 as the default for `getCmpLibcallReturnType`, but
compiler-rt uses a word-sized integer by default. On most physical
hardware this happens to work because `i32` is largely ABI-compatible
with a word. On wasm64, however, they are not compatible so this causes
problems.
Resolve this by using `int` as the comparison result in compiler-rt.

- Issue a warning for mismatches in function types.
- Ignore type discrepancies for variables.
This behavior aligns with similar diagnostics in GCC.

Linux Kernel has removed scc.h header completely from the source code

https://github.com/torvalds/linux/commit/64edfa65062dc4509ba75978116b2f6d392346f5#diff-1ca78e598a5041ee51ae795d168435afad598b82a7a0ce80f215993589b96c7c
Without removing it, not only it breaks compiler-rt but also GCC build
since GCC always builds libsanitizer for linux targets.
After merging this we will need to cherry pick to GCC.

[RISCV][GlobalISel] Support RISC-V specific inline asm constraints: 'I', 'J', 'K' and 'S' (#193765)
This patch implements some target-specific constraints for RISC-V: `I`,
`J`, `K` and `S`. These constraints are all for immediate values except
for `S`. The handling of these constraints is implemented with by adding
`RISCVInlineAsmLowering` subclass of `InlineAsmLowering`.

[LoongArch] Combine rounded vector shifts to VSRLR/VSRAR (#192921)
Add DAG combines to recognize canonical rounded shift patterns and lower
them to target-specific vector rounded shift instructions.
The combines match vector arithmetic and logical right shifts with
rounding implemented as:
```
add (srl/sra X, shift),
(and (srl X, shift-1), 1)
```
and the shift-by-1 variant:
```
add (srl/sra X, 1),
(and X, 1)
```
Additionally, handle the guarded form generated when shift may be zero:
```
vselect (setcc shift, 0, seteq),
X,
rounded_shift
```
and fold it to the corresponding rounded shift instruction.
Define new target DAG nodes VSRLR and VSRAR and add instruction
selection patterns for both LSX and LASX, including register and
immediate shift forms.

[clang] Tests for CWG1670 and CWG1878: `auto` in conversion functions (#187850)
This PR adds tests for
[CWG1670](https://cplusplus.github.io/CWG/issues/1670.html) "`auto` as
_conversion-type-id_" and
[CWG1878](https://cplusplus.github.io/CWG/issues/1878.html) "`operator
auto` template". The long and short of it is that placeholder type
specifier (`auto`) cannot be used to declare conversion function or
conversion function template. We've always diagnosed template case but
not non-template case.

[asan] API for getting multiple pointer ranges (#181446)
Add an API that, unlike __asan_get_report_address(), can return multiple
addresses and sizes. This allows a handler to inspect the source and the
destination ranges of errors that have more than one pointer involved
(e.g., memcpy-param-overlap).
Fixes #155406.

[libc++] Fix constant_wrapper::operator() (#193573)
As Tomasz pointed out on mattermost,
given
```cpp
template <class T>
struct MustBeInt {
static_assert(std::same_as<T, int>);
};
struct Poison {
template <class T>
constexpr auto operator()(T) const noexcept -> MustBeInt<T> {
return {};
}
};
std::cw<Poison{}>(std::cw<5>);
```
This should work according to the wording
https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2026/p3978r3.pdf
```cpp
template<class... Args>
static constexpr decltype(auto) operator()(Args&&... args) noexcept(see below);
```
```
- Let call-expr be constant_wrapper<INVOKE (value, remove_cvref_t<Args>::value...)>{} if all types
in remove_cvref_t<Args>... satisfy constexpr-param and constant_wrapper<INVOKE (value, remove_-
cvref_t<Args>::value...)> is a valid type, otherwise let call-expr be INVOKE (value, std::forward<Args>(args)...).
- Constraints: call-expr is a valid expression.
- Effects: Equivalent to: return call-expr;
- Remarks: The exception specification is equivalent to noexcept(call-expr).
```
so basically the spec says, there are two cases
- constexpr-param case
- runtime case
and if constexpr-param case works, uses it, otherwise fallback to
runtime case if it is valid, otherwise substitution error.
In this case, `std::cw<5>` satisfy `constexpr-param`, and
`constant_wrapper<Poison{}(5)>` is valid , it should just work. however,
our implementation implemented the two cases in two overload
```cpp
template <class... _Args>
requires(__constexpr_param<remove_cvref_t<_Args>> && ...)
_LIBCPP_HIDE_FROM_ABI static constexpr auto __call(_Args&&...) noexcept
-> constant_wrapper<std::invoke(value, remove_cvref_t<_Args>::value...)> {
return {};
}
template <class... _Args>
_LIBCPP_HIDE_FROM_ABI static constexpr auto
__call(_Args&&... __args) noexcept(noexcept(std::invoke(value, std::forward<_Args>(__args)...)))
-> decltype(std::invoke(value, std::forward<_Args>(__args)...)) {
return std::invoke(value, std::forward<_Args>(__args)...);
}
```
The logic is that, both overloads use return type SFINAE and the
constexpr-param case's concept is more constrained so it will be picked
first if constexpr-param case works.
However, in this example, the second overload's return type SFINAE
causes a hard error by the `static_assert` in the user code.
The fix is simply constrain the second overload and not using return
type SFINAE so it short circuits if constexpr-param case is valid.
As a drive by, removed the internal helper function and directly make
the public interface `operator()` two overloads so that we can apply
`[[nodiscard]]` on the constexpr-param case

[Clang][RISCV] Introduce OFP8(E4M3, E5M2) RISC-V vector types (#191349)
Currently there's no OFP8 scalar type supported in both clang and llvm
type system, the vector OFP8 RVV types are lowered to i8 llvm types for
now.
The reason to support only clang type is because of intrinsics
definition capability. If we make the clang type also using uint8 vector
types, it's not able to distinguish between E4M3 type and E5M2 type so
that we have to append additional type suffix to it.

[mlir][math] Add rounding modes to `math.fma` (#192839)
Rounding modes have recently been added for `arith` FP operations
(#188458). This commit adds rounding modes to `math.fma`, following the
same design as for `arith` FP operations.
If a rounding mode is present, the LLVM lowering produces
`llvm.intr.experimental.constrained.fma`.
In the absence of a rounding mode, the rounding behavior is deferred to
the target backend.

[flang][OpenMP] Replace llvmOmpClause with llvm::omp::Clause (#194162)
Both types, llvmOmpClause (alias of const llvm::omp::Clause) and
llvm::omp::Clause are in use, let's just stick with one.

[clang] Make serenity.cpp more independent of the host (#193981)
Tests matching crt files previously relied on the host system not using
the same file paths as Serenity. This breaks on AIX, as both systems use
`/usr/lib/crt0.o`.
Redirect most tests to an empty sysroot so they match only on the
filename and remain independent of the host system. Also add a test that
verifies crt files can be found in a normal sysroot.

The compiler version was bumped in

include this. We should probably just hash pin the version in future
workflows for future toolchain upgrades.

[VPlan] Fix assert in finding WideCanIV (NFC) (#193269)
addActiveLaneMask asserts that the return value of a find_if is
contextully convertible to true, when finding a WideCanonicalIV recipe:
what it should really be checking that the iterator is not the end
iterator. Fix this assert by introducing and using a variant of
vputils::findUserOf.

[BOLT] Support negative hex in pre-aggregated profile (#192391)
Handle signed values in parseHexField by falling back to int64_t parsing
when uint64_t fails. This allows pre-aggregated profile tools to use -1
for BR_ONLY, -2 for FT_EXTERNAL_ORIGIN, -3 for FT_EXTERNAL_RETURN.
Guard the external address reset loop in parseAggregatedLBREntry to
preserve sentinel values (offsets >= FT_EXTERNAL_RETURN).
Add tests for -1/-2/-3 in parseHexField and T entries with -1,
ffffffffffffffff, and buildid:-1 as BR_ONLY.

[BOLT] Add tests for pre-aggregated parsing (#193843)
Extends e2e coverage of pre-aggregated profile parsing to match the
unit-test coverage added in #192390:
- R (Return) records, including the branch=0 fallback path that
rewrites to the FT_EXTERNAL_RETURN sentinel.
- r (FT_EXTERNAL_RETURN) records.
- B and T records using the negative -1 hex form (#192391),
which is parsed as the BR_ONLY/FT_ONLY sentinel.
- Error paths: invalid record type letter and malformed hex address
(perf2bolt is expected to exit non-zero with a parser error).
The two error-path inputs are tiny raw files under Inputs/ since they
contain intentionally malformed records that link_fdata doesn't process.

[MC] Always lower .fill to MCFillFragment (#194164)
Constant-count, constant-pattern .fill expands inline into the current
fragment via emitIntValue per byte, wasting both memory and time (a
redundant copy at MCAssembler.cpp). #50974 reports a 4s compile dropping
to 0.6s when the loop is removed.
Drop the inline path so .fill always becomes MCFillFragment.
This cannot be done before commit 507efbcce03d (2023) allowed
label differences to be separated by a MCFillFragment.
In directive_fill.s, the parse time warning is now diagnosed by
MCAssembler.

[MC] Drop MCTargetOptions parameter from MCTargetAsmParser (#194120)
Since #180464, MCAsmInfo holds the canonical MCTargetOptions.
The MCTargetAsmParser::MCOptions member is a redundant by-value copy,
which may have inconsistent values (llvm-exegesis passes a temporary
MCTargetOptions(), but this probably doesn't matter in practice; other
in-tree uses are correct).
Remove the field in favor of getParser().getContext().getTargetOptions,
and remove the MCTargetOptions parameter from the base ctor, all
subclass ctors, Target::createMCAsmParser, MCAsmParserCtorTy, and
RegisterMCAsmParser.

[compiler-rt] Use asm .set only for Hexagon (#194160)
Two incompatible assembler syntaxes exist for symbol assignment:
```
sym = val -- accepted by most GNU assembler targets; rejected by
Hexagon, which interprets it as a mnemonic
.set sym, val -- accepted by Hexagon; rejected by Alpha, which
reserves .set for assembler mode flags
```
Switch all to `sym = val`, and opt out Hexagon to `.set sym`.

Summary:
Previously, `nvptx64--` would reject `nvptx64-unknown-unknown`. Two
options, either normalize all the triples in CMake, or just check the
architecture. I went with the former because it makes it easier for
people to pass different values.

[MC] Add MCTargetOptions to MCAsmInfo constructor. NFC (#194200)
Since #180464 the canonical MCTargetOptions pointer is stored in
MCAsmInfo, but it is bound after construction via `setTargetOptions`
called from TargetRegistry::createMCAsmInfo.
Direct constructions in unit tests can leave the pointer null, leading
to a runtime assert failure. Add MCTargetOptions to every MCAsmInfo
subclass constructor, store it as a reference in MCAsmInfo, and remove
`setTargetOptions()`.

[SLP] Fix spill-cost cache lookup and predecessor scan
A cached intra-block scan that stopped at a call or budget limit only
proves the sub-range below the stop point is call-free; do not reuse
the cached bit for queries whose First lies above it. Also switch the
cross-block predecessor scan to "exists a call-free backward path"
semantics, skip blocks strictly dominated by Root, and memoize only
the (Root, OpParent) key. Fixes a false-positive spill cost that was
blocking profitable vectorization.

[InstCombine] Div ceil optimizations (#190175)
Relates: https://github.com/llvm/llvm-project/issues/187838
This PR improves handling of `div_ceil` from rust (which emits a div +
rem).
Currently, these three rust functions:
```rust
use std::hint::assert_unchecked;
#[unsafe(no_mangle)]
pub fn div_ceil_without_assume(x: u32) -> u32 {
x.div_ceil(7)
}
#[unsafe(no_mangle)]
pub fn div_ceil_with_assume(x: u32) -> u32 {
unsafe {
assert_unchecked(x <= u32::MAX - 7);
}
x.div_ceil(7)
}
#[unsafe(no_mangle)]
pub fn div_ceil_with_range(x: u32) -> u32 {
x.count_zeros().div_ceil(7)
}
```
Will emit this IR (cleaned up): The IR looks pretty good to me as both
the assert_unchecked and the popcount are providing range information.
```llvm
define noundef range(i32 0, 613566758) i32 @div_ceil_without_assume(i32 noundef %x) unnamed_addr {
start:
%d = udiv i32 %x, 7
%r = urem i32 %x, 7
%_4.not = icmp ne i32 %r, 0

}

After running through opt and llc on main with popcnt for less noise:
`build/bin/opt -O2 -S < test.ll | build/bin/llc --x86-asm-syntax=intel
-mattr=+popcnt -O2 -o -`
```asm
div_ceil_without_assume: # @div_ceil_without_assume
mov eax, edi

(as a sidenote, just running llc seems to generate better code? I find
this a bit odd)
`build/bin/llc test.ll --x86-asm-syntax=intel -mattr=+popcnt -O2 -o -`
```asm

Anyway the llvm IR when run through opt at -O2:
On main:
The only changes I see are the urem being rewritten to a mul + sub for
all the instructions, and the range information is persisted but not
used.
```llvm
define noundef range(i32 0, 613566758) i32 @div_ceil_without_assume(i32 noundef %x) unnamed_addr {

define noundef range(i32 0, 613566757) i32 @div_ceil_with_assume(i32 noundef %x) unnamed_addr {

ret i32 %_0.sroa.0.0
}

%d.lhs.trunc = trunc nuw nsw i32 %0 to i8
%d3 = udiv i8 %d.lhs.trunc, 7
%d.zext = zext nneg i8 %d3 to i32
%1 = mul i8 %d3, 7
%r4.decomposed = sub i8 %d.lhs.trunc, %1
%_6.not = icmp ne i8 %r4.decomposed, 0
%2 = zext i1 %_6.not to i32
%_0.sroa.0.0 = add nuw nsw i32 %2, %d.zext
ret i32 %_0.sroa.0.0
}
declare void @llvm.assume(i1 noundef)
declare i32 @llvm.ctpop.i32(i32)
```
However, both the assume and the popcount provide range information so
we can do an optimization. Div_ceil is emitted as a udiv and urem. We
can combine them given the following rules:
Assuming you have floor division of X / Y, we can add Y - 1 to X and
floor division will always give us (floor_divide(X / Y) + 1) which gives
us the same result.
So the formula in general is:
```
div_ceil(X, Y) = X / Y + (1 if X % Y > 0 else 0) -> X + Y - 1 / Y
```
But this fails since I forgot about wrapping. So we need a condition
that X + Y - 1 does not wrap, and of course Y cannot be 0. Technically
we should ignore Y / 1 since that's a trivial identity.
That gets us:
```
add(udiv(X, Y), zext(icmp ne(urem(X, Y), 0))) -> udiv(add nuw(X, Y - 1), Y)
```
[Alive proof here](https://alive2.llvm.org/ce/z/nBvyv4)
This is where I thought I was done, because this should handle the range
and assume case (the assume case provides less information than the
popcount because popcount's range is narrower for X). So I thought I was
done.
Unfortunately this only optimizes one case (the assume case with the
wide code). The culprit here is in the popcount case, there's a trunc
for the popcount to bound it to an i8 since narrower arithmetic allows
for better optimizations before zero extending.
```llvm
%d.lhs.trunc = trunc nuw nsw i32 %0 to i8
%d3 = udiv i8 %d.lhs.trunc, 7
%d.zext = zext nneg i8 %d3 to i32
%r4 = urem i8 %d.lhs.trunc, 7
%_6.not = icmp ne i8 %r4, 0
%1 = zext i1 %_6.not to i32
```
So we need to handle another form, when the udiv needs to be zexted to
the return type (because it was previously trunced, due to the
popcount).
```
add(zext(udiv(X, Y)), zext(icmp ne(urem(X, Y), 0))) -> zext(udiv(add nuw(X, Y - 1), Y))
```
[Alive2 Proof](https://alive2.llvm.org/ce/z/w7bRZW)
There was another oddity I found that trunced information wasn't passing
constant ranges, so I added that to ValueTracking.cpp to fix this fold
too.
On this branch the IR now transforms:
```llvm
define noundef range(i32 0, 613566758) i32 @div_ceil_without_assume(i32 noundef %x) unnamed_addr {
start:
%d = udiv i32 %x, 7
%0 = mul i32 %d, 7
%r.decomposed = sub i32 %x, %0
%_4.not = icmp ne i32 %r.decomposed, 0
%1 = zext i1 %_4.not to i32
%_0.sroa.0.0 = add nuw nsw i32 %d, %1

[AArch64] Optimize vector fmul(sitofp/uitofp, 1/2^N) -> scvtf/ucvtf (#141480)
When a vector integer-to-float conversion is followed by a multiply with a
reciprocal power-of-two constant, we can fold both operations into a single
SCVTF or UCVTF instruction with a fixed-point shift operand.
For example, `fmul(sitofp(v2i32 x), <0.5, 0.5>)` becomes `scvtf.2s v0, v0, #1`.
This is a reworked version with several improvements over the original
submission:
- Rewrite the C++ operand matcher to share implementation with the existing
`SelectCVTFixedPointVec` (MOVIshift, FMOV, and DUP handling with correct
truncation for f16)
- Add `uitofp`/`ucvtf` patterns via a `CVTFRecipPat` multiclass
- Add full GlobalISel support (`GIComplexOperandMatcher` + renderer)
Supported vector types: `v2f32`, `v4f32`, `v2f64`, `v4f16`, `v8f16`.

lldb-dap: Fix race condition in event threads creation (#194012)
Move the registration of the SBListener to before
the event threads (`ProgressEventThread` and `EventThread`) start
This prevents a race condition where a stop event
could be missed if it was sent immediately after thread creation, which
would lead to a deadlock. It is most likely to happen under heavy CPU
load with test that fails early like
TestDAP_commands::test_command_directive_abort_on_error_init_commands.

[sanitizer] Fix race condition in GetNamedMappingFd with decorate_pro… (#190981)
…c_maps=1
Multi-threaded programs crash randomly when
ASAN_OPTIONS=decorate_proc_maps=1 is enabled due to filename collision
in /dev/shm.
Root Cause:
All threads use the same filename format '/dev/shm/<PID> [name]',
causing race conditions where one thread deletes a file created by
another thread, resulting in ENOENT errors.
Solution:
Add thread ID (TID) to the filename to ensure uniqueness:
- Old format: /dev/shm/<PID> [name]
- New format: /dev/shm/<PID>.<TID> [name]
This ensures each thread has a unique filename, eliminating the race
condition.
Testing:
- Original version: 30% crash rate (6 crashes in 20 runs)
- Fixed version: 0% crash rate (0 crashes in 50 runs)

but it turns out it's not true.

[GVN] Propagate isMemorySSAEnabled() into ValueTable (#193938)
`GVNPass::runImpl()` calls `VN.setMemorySSA(MSSA)` with a single
argument. The second parameter of `ValueTable::setMemorySSA()`,
`MSSAEnabled`, defaults to `false`, so `ValueTable::IsMSSAEnabled`
remains false even when the pass is configured with
`-enable-gvn-memoryssa=1` or `-passes='gvn<memoryssa>'`.
The MemorySSA-backed value-numbering paths in
`ValueTable::lookupOrAddCall()` and `ValueTable::computeLoadStoreVN()`
are gated on `IsMSSAEnabled`, making them unreachable from runImpl() on
main today.
This patch forwards isMemorySSAEnabled() as the second argument to
setMemorySSA(), so selecting the MemorySSA backend actually enables
MemorySSA-aware value numbering.

AMDGPU: Back-propagate wqm for sources of side-effect instruction (#193395)
For readfirstlane instruction, as it would get undefined value if exec
is zero. To handle the case that only helper lanes execute the parent
block, we let the readfirstlane to execute under wqm. But this is not
enough. If the parent block was also executed by non-helper lanes, we
also need to make sure its sources were calculated under wqm. Otherwise,
if the instruction that generate the source of readfirstlane was
executed under exact mode, the value would contain garbage data in help
lane. The garbage data in helper lane maybe returned by the
readfirstlane running under wqm.
To fix this issue, we need to enforce the back-propagation of wqm for
instructions like readfirstlane. This was only done if the instruction
was possibly in the middle of wqm region (by checking OutNeeds).

On 64-bit targets the generic legalize will use an i64 load and a
scalar_to_vector for us. But on 32-bit targets, i64 isn't legal, and the
generic legalizer will end up emitting two 32-bit loads. This patch uses
f64 to avoid the splitting entirely and the redundant int->fp
conversion.

[flang] only instantiate required symbols from parent modules (#193689)
Currently lowering is instantiating (creating
fir.address_of/hlfir.declare) for all module variables from host module
and submodules (for instance, in the new
host_module_variable_instantiation.f90 test, a fir.address_of was
generated the unused var2 inside the procedure foo).
This created a lot of noise (and in the worst cases, compile time
performance issues), and also some extra complexity at least for OpenACC
where the IR acc routine ended up referencing globals that are no
actually needed, creating the need to copy them on the GPU or to have
custom logic to ignore the globals.
This patch addresses this by doing a visit of the parse tree to detect
the required symbols and only instantiate those.

[AArch64] Sanitise pow inputs using a target DAG combine (#192958)
Sometimes we see LLVM IR like this:
%pow = call fast <4 x float> @llvm.pow.v4f32(...)
%fcmp = fcmp fast ...
%res = select <4 x i1> %fcmp, <4 x float> %val, <4 x float> %pow
where the pow intrinsic is called unconditionally, but only certain
lanes of the result are used. In fact, LLVM actively encourages code
like this due to the intrinsic being marked as safe to speculatively
execute. However, we know when using certain vector libraries like
ArmPL that this can be very costly if the unused lanes would take
the pow call down an expensive path. For example, if an input to
pow is a special value (inf, NaN, -0) then it triggers slow special
case handling, and ultimately the result is going to be ignored
anyway. For this reason we prefer to sanitise the pow input to
use 'safe' values when we know the result is going to be discarded.
The above example LLVM IR would then look like
%fcmp = fcmp fast ...

[ADT] Fix IWYU for hashing-adjacent files (#194297)
Add explicit includes so these files keep building after we trim
transitive includes from xxhash.h.
For example, FoldingSet.cpp calls llvm::uninitialized_copy, which is
declared in llvm/ADT/STLExtras.h and today reaches the file only
transitively.
Also drop the vestigial `#include "llvm/ADT/Hashing.h"` from
llvm/ADT/STLExtras.h — no name from Hashing.h is used there.

[libc] Add struct cmsghdr and associated macros (#193756)
The macros are the main source of subtlety. The interesting aspects are:
- some implementations CMSG_ALIGN the size of struct cmsghdr, but this
is a noop. Instead of doing that, I added an assertion in the test.
- POSIX permits CMSG_NXTHDR to return null if the buffer has no space
for the data array, and this behavior differs between implementations.
This implementation does not do that in order to match CMSG_FIRSTHDR,
which doesn't have such an option.
- some implementations redirect the CMSG_NXTHDR macro to an (extern or
static inline) function. I implemented this inside the macro to avoid
having to define a (private ?) entry point for that function.

[AggressiveInstCombine] Fold split-width i32 cttz/ctlz patterns into wide i64 intrinsics (#192296)
This patch teaches `AggressiveInstCombine ` to recognize and fold common split-width i32 cttz/ctlz intrinsic calls into a single full-width i64
cttz/ctlz intrinsic.
For ex:
```
define i32 @src(i64 %val) {
%lo = trunc i64 %val to i32
%cmp = icmp eq i32 %lo, 0
%shr = lshr i64 %val, 32
%hi = trunc i64 %shr to i32
%cttz_hi = call i32 @llvm.cttz.i32(i32 %hi, i1 true)
%hi_plus32 = or i32 %cttz_hi, 32
%cttz_lo = call i32 @llvm.cttz.i32(i32 %lo, i1 true)
%result = select i1 %cmp, i32 %hi_plus32, i32 %cttz_lo
ret i32 %result
}
define i32 @tgt(i64 %val) {
%cttz64 = call i64 @llvm.cttz.i64(i64 %val, i1 false)
%result = trunc i64 %cttz64 to i32
ret i32 %result
}
```
and similarly for ctlz intrinsic.
Alive proof for the 2 folds added by this patch.

[memref] Simplify loads from reinterpret_cast of 1D contiguous memrefs (#188459)
Rewrite `memref.load` operations whose source is a `reinterpret_cast` that
represents a rank reshape of a 1D contiguous `memref` with a single non-unit
dimension.
Assisted-by: ChatGPT (refine implementation + tests). I reviewed all code and
tests before submission.
## Example
Before:
```mlir
%reinterpret_cast = memref.reinterpret_cast %src
to offset: [0], sizes: [1, 1, 999], strides: [999, 999, 1]
: memref<999xi64> to memref<1x1x999xi64>
%0 = memref.load %reinterpret_cast[%c0, %c0, %i]
: memref<1x1x999xi64>
```
After:
```mlir
%0 = memref.load %src[%i] : memref<999xi64>
```
## Motivation
This simplifies the IR, makes indexing explicit, and reduces indirection,
which in turn improves downstream transformations and lowerings (e.g. EmitC).
## Scope
This rewrite is intentionally narrow:
- Applies only to rank-expansion and rank-collapsing of a contiguous 1D buffer
(at most one non-unit dimension).
- Requires `reinterpret_cast` with zero offset and fully static sizes and
strides.
- Requires the non-unit dimension to be at a boundary (first or last).
- Requires any dropped indices (from size-1 dimensions) to be statically zero.
It does **not** handle:
- general `memref.reinterpret_cast` with arbitrary strides or offsets
- multiple non-unit dimensions
- cases where index dropping would change semantics
For example:
```mlir
%reinterpret_cast = memref.reinterpret_cast %src
to offset: [0], sizes: [1, 1, 1, 108], strides: [108, 108, 108, 1]
: memref<1x108xf32> to memref<1x1x1x108xf32>
%0 = memref.load %reinterpret_cast[%c0, %c1, %c0, %c0]
: memref<1x1x1x108xf32>
```
The pattern would skip `%c1` when forming the indices for the replacement load,
since it cuts the dimensions that were added to the left, including the
dimension where the non-zero index is:
```mlir
%0 = memref.load %src[%c0, %c0]
: memref<1x108xf32>
```
causing the rewrite to discard a non-zero index on a size-1 dimension, which is
not semantics-preserving.
## Correctness
In the accepted cases, the cast is a pure view that does not alter memory
layout. Size-1 dimensions do not contribute to address computation, and the
single non-unit dimension determines the access.
Dropping indices for size-1 dimensions (or inserting zeros when collapsing
rank) preserves the computed address. The rewrite is only applied when such
indices are statically zero, ensuring in-bounds semantics.
Therefore, the rewritten load is equivalent to the original load through the
`reinterpret_cast`

Previously, IMPLICIT_DEF instructions were not copied into the

machine-level liveness inconsistent with the triplicated code and could
trigger a LiveIntervals assertion:
LiveIntervals::HMEditor::updateRange: Assertion `LR.verify()' failed.
Copy IMPLICIT_DEF into the triple region so that the triplicated block
has a consistent set of defs and LiveIntervals can update ranges
correctly.

[Clang] No longer advertise support for coroutines on x86 windows. (#193456)
There are a large number of long standing issues with coroutines on
x86_32 windows as discussed here
https://github.com/llvm/llvm-project/issues/59382
- #59382
- #58556
- #58543
- #56989
- #193161
- #136481
As such this patches
- No longer defines `__cpp_impl_coroutine` on that platform
- Warn when using coroutines on that platform
The reason to not plainly error is that it would break too much valid
valid code, ie there are people who probably use coroutines sucessfully.
And we also want to keep testing on that platform, up until the point we
were to pull support completely.
Hopefully this is all temporary and someone will feel compelled to
improve the situation enough that we can unceremoniously revert this
patch.

[clang][CodeView] Prevent the input name from appearing in LF_BUILDINFO (#194140)
The implicit contract of an `LF_BUILDINFO` record (represented in LLVM
by
[`BuildInfoRecord`](https://github.com/llvm/llvm-project/blob/6f0b55ec55f3e5e1ccc0d6b0d04a307479218768/llvm/include/llvm/DebugInfo/CodeView/TypeRecord.h#L667))
is that its `CommandLine` field should not contain the input source file
— a separate `SourceFile` field is reserved for that.
When the command-line flattening was moved from `llvm/` to `clang/` in
#106369, the comparison value used to identify and strip the source
positional was switched from `MainSourceFile->getFilename()` (the full
input path resolved by clang) to `CodeGenOpts.MainFileName` (just the
basename, set via `-main-file-name`). As a result, when the driver is
invoked with an absolute source path the cc1 positional is that absolute
path and no longer matches `MainFileName`, so the source filename leaks
into `CommandLine` as a trailing positional cc1 argument.
This is a regression in Clang 20. It breaks downstream tooling such as
Live++, whose unity-splitting feature relies on the embedded command
line being the cc1 invocation minus the source. Reported in #193900.
This PR restores the previous behavior by passing the resolved frontend
input path(s) to `flattenClangCommandLine` and including them in the
equality check that strips the source positional. The basename match
against `MainFileName` is kept for the relative-input case. A regression
test (and a symmetric relative-path test) is added to
`clang/test/DebugInfo/Generic/codeview-buildinfo.c`.
Should fix #193900.

[HLSL] Handle logical pointer for array assign (#193227)
This commits adds SPIR-V testing on an existing test (almost-NFC on DXIL
testing). It also copies it and invokes Clang using the experimental
logical pointer flag.
Adding this flag shows a missing case in the frontend, handled with this
commit.
Due to the difference in index handling between the structured.gep and
legacy one, the Cbuffer load codegen had to be rewritten. It's a bit
more naive, as we get one gep per level, but this will be handled by
optimizations later on.

[MLIR][OpenMP] Remove Generic-SPMD early detection (#150922)
This patch removes logic from MLIR to attempt identifying Generic
kernels that could be executed in SPMD mode.
This optimization is done by the OpenMPOpt pass for Clang and is only
required here to circumvent missing support for the new DeviceRTL APIs
used in MLIR to LLVM IR translation that Clang doesn't currently use
(e.g. `kmpc_distribute_static_loop` ). Removing checks in MLIR avoids
duplicating the logic that should be centralized in the OpenMPOpt pass.
Additionally, offloading kernels currently compiled through the OpenMP
dialect fail to run parallel regions properly when in Generic mode. By
disabling early detection, this issue becomes apparent for a range of
kernels where this was masked by having them run in SPMD mode.

[MLIR][OpenMP] Support allocations of device shared memory (#150924)
This patch updates the allocation of some reduction and private
variables within target regions to use device shared memory rather than
private memory. This is a prerequisite to produce working Generic
kernels containing parallel regions.
In particular, the following situations result in the usage of device
shared memory (only when compiling for the target device if they are
placed inside of a target region representing a Generic kernel):
- Reduction variables on `teams` constructs.
- Private variables on `teams` and `distribute` constructs that are
reduced or used inside of a `parallel` region.
Currently, there is no support for delayed privatization on `teams`
constructs, so private variables on these constructs won't currently be
affected. When support is added, if it uses the existing
`allocatePrivateVars` and `cleanupPrivateVars` functions, usage of
device shared memory will be introduced automatically.

[OpenMP][OMPIRBuilder] Use device shared memory for arg structures (#150925)
Argument structures are created when sections of the LLVM IR

function. For this, stack allocations are used.
This patch modifies this behavior when compiling for a target device and
outlining `parallel`-related IR, so that it uses device shared memory
instead of private stack space. This is needed in order for threads to
have access to these arguments.

[OpenMPOpt] Make parallel regions reachable from new DeviceRTL loop functions (#150927)
This patch updates the OpenMP optimization pass to know about the new
DeviceRTL functions for loop constructs.
This change marks these functions as potentially containing parallel
regions, which fixes a current bug with the state machine rewrite
optimization. It previously failed to identify parallel regions located
inside of the callbacks passed to these new DeviceRTL functions, causing
the resulting code to skip executing these parallel regions.
As a result, Generic kernels produced by Flang that contain parallel
regions now work properly.
One known related issue not fixed by this patch is that the presence of
calls to these functions will prevent the SPMD-ization of Generic
kernels by OpenMPOpt. Previously, this was due to assuming there was no
parallel region. This is changed by this patch, but instead we now mark
it temporarily as unsupported in an SPMD context. The reason is that,
without additional changes, code intended for the main thread of the
team located outside of the parallel region would not be guarded
properly, resulting in race conditions and generally invalid behavior.

[OMPIRBuilder] Add support for explicit deallocation points (#154752)
In this patch, some OMPIRBuilder codegen functions and callbacks are
updated to work with arrays of deallocation insertion points. The
purpose of this is to enable the replacement of `alloca`s with other
types of allocations that require explicit deallocations in a way that
makes it possible for `CodeExtractor` instances created during
OMPIRBuilder finalization to also use them.
The OpenMP to LLVM IR MLIR translation pass is updated to properly store
and forward deallocation points together with their matching allocation
point to the OMPIRBuilder.
Currently, only the `DeviceSharedMemCodeExtractor` uses this feature to
get the `CodeExtractor` to use device shared memory for intermediate
allocations when outlining a parallel region inside of a Generic kernel
(code path that is only used by Flang via MLIR, currently). However,
long term this might also be useful to refactor finalization of
variables with destructors, potentially reducing the use of callbacks
and simplifying privatization and reductions.
Instead of a single deallocation point, lists of those are used. This is
to cover cases where there are multiple exit blocks originating from a
single entry. If an allocation needing explicit deallocation is placed
in the entry block of such cases, it would need to be deallocated before
each of the exits.

[Flang][MLIR][OpenMP] Add explicit shared memory (de-)allocation ops (#161862)
This patch introduces the `omp.alloc_shared_mem` and
`omp.free_shared_mem` operations to represent explicit allocations and
deallocations of shared memory across threads in a team, mirroring the
existing `omp.target_allocmem` and `omp.target_freemem`.
The `omp.alloc_shared_mem` op goes through the same Flang-specific
transformations as `omp.target_allocmem`, so that the size of the buffer
can be properly calculated when translating to LLVM IR.
The corresponding runtime functions produced for these new operations
are `__kmpc_alloc_shared` and `__kmpc_free_shared`, which previously
could only be created for implicit allocations (e.g. privatized and
reduction variables).

[Flang][OpenMP] Add pass to replace allocas with device shared memory (#161863)
This patch introduces a new Flang OpenMP MLIR pass, only ran for target
device modules, that identifies `fir.alloca` operations that should use
device shared memory and replaces them with pairs of
`omp.alloc_shared_mem` and `omp.free_shared_mem` operations.
This works in conjunction to the MLIR to LLVM IR translation pass'
handling of privatization, mapping and reductions in the OpenMP dialect
to properly select the right memory space for allocations based on where
they are made and where they are used.
This pass, in particular, handles explicit stack allocations in MLIR,
whereas the aforementioned translation pass takes care of implicit ones
represented by entry block arguments.

[MLIR][OpenMP][OMPIRBuilder] Improve shared memory checks (#161864)
This patch refines checks to decide whether to use device shared memory
or regular stack allocations. In particular, it adds support for
parallel regions residing on standalone target device functions.
The changes are:
- Shared memory is introduced for `omp.target` implicit allocations,
such as those related to privatization and mapping, as long as they are
shared across threads in a nested parallel region.
- Standalone target device functions are interpreted as being part of a
Generic kernel, since the fact that they are present in the module after
filtering means they must be reachable from a target region.
- Prevent allocations whose only shared uses inside of an `omp.parallel`
region are as part of a `private` clause from being moved to device
shared memory.

[AArch64] Enable Spillage Copy Elimination by default (#186093)
In times of high register pressure, the greedy register allocator can
emit large eviction chains that consist of many `mov` instructions. The
Spillage Copy Elimination pass handles this, by finding these chains and
decreasing their impact. Take a mov chain such as the following where
`x8` is used for an 8-byte Folded Reload:
```
mov x7, x6
mov x6, x5
mov x5, x4
mov x4, x3
mov x3, x2
mov x2, x1
mov x1, x30
mov x30, x8
< use x8 >
mov x8, x30
mov x30, x1
mov x1, x2
mov x2, x3
mov x3, x4
mov x4, x5
mov x5, x6
mov x6, x7
```
Becomes:
```
mov x7, x6
mov x6, x8
< use x8 >
mov x8, x6
mov x6, x7
```
This provides performance benefits for long mov chains, where we are no
longer needing to copy these values between registers.
This does introduce compile time regressions, as was originally noted in
the initial review. From my testing, this was around 0.17% on average
using LLVM Test Suite.

transformation wrappers to find the actual do construct, instead of
assuming it is directly nested.

[InstCombine] Require one-use intermediate binop in foldBinOpShiftWithShift (#194341)
foldBinOpShiftWithShift rewrites
binop(shift(X,C) op Mask, shift(Y,C))
to
binop(shift(X+Y,C), Mask).
Both shifts are matched with m_OneUse, but the enclosing binop that
wraps (shift(X,C), Mask) is not. When that binop has additional users
the rewrite cannot eliminate the originals and only adds new
instructions. The reproducer in the issue shows this: a shared base
with several downstream consumers gets duplicated on each one, so the
fold grows the IR instead of shrinking it.
Wrap the outer m_c_BinOp in m_OneUse so the fold only fires when the
binop can actually be replaced. Mirrors the one-use discipline already
applied to both shifts in the same matcher.
Fixes #194007.

[Clang] prevent crash in delayed default-argument lambda captures (#176749)
Fixes #176534
---
This patch resolves a crash when parsing delayed default arguments that
contain lambda expressions.
```cpp
struct S {
void f(int x, int = sizeof([x] { return x; }()));
};
```
When late-parsing default arguments that contain lambdas, `Sema` builds
a `FunctionScopes` stack containing only the lambda scope
(`FunctionScopes.size()` equals 1), however, `tryCaptureVariable`
expects an enclosing function scope outside the lambda scope
https://github.com/llvm/llvm-project/blob/41e231cae38028473dd327e8de5f65792b521ffe/clang/lib/Sema/SemaExpr.cpp#L19473-L19474

Scope capture handling logic decrements `FunctionScopesIndex` to align
declaration contexts
https://github.com/llvm/llvm-project/blob/41e231cae38028473dd327e8de5f65792b521ffe/clang/lib/Sema/SemaExpr.cpp#L19696
and later relies on it when traversing and accessing outer scopes
https://github.com/llvm/llvm-project/blob/41e231cae38028473dd327e8de5f65792b521ffe/clang/lib/Sema/SemaExpr.cpp#L19522-L19524
preserving the function scope in the late-parsing path prevents invalid
traversal during lambda capture handling

performed inside that function. No need to forward a dummy success error

[LiveDebugValues] Use std::sort for register sorting in collectIDsForRegs (#194339)
VarLocBasedLDV::collectIDsForRegs sorts a SmallVector<Register> using
array_pod_sort which is a thin wrapper around qsort. That shows up as a hotspot
in compile-time profiles under __GI___qsort_r.
Switching this to an explicit-comparator llvm::sort call, which takes the
std::sort path instead improves compile-time with no change to code-size.

This fixes an instruction incorrectly being marked as dead and optimized

Fixes #187690
---
This PR fixes parser recovery for invalid `static_assert` declarations
with string literal messages. The parser now stops the message lookahead
on `;` and `eof`, so invalid inputs are diagnosed as parse errors.

[lldbremote][NFC] Factor out code handling breakpoint packets (#192915)
This commit extracts the code handling breakpoint packets into a helper
function that can be used by a future implementation of the
MultiBreakpointPacket.
It is meant to be purely NFC.
There are two functions handling breakpoint packets (`handle_Z` and
`handle_z`) with a lot of repeated code. This commit did not attempt to
merge the two, as that would make the diff much larger due to subtle
differences in the error message produced by the two. The only
deduplication done is in the code processing a GDBStoppointType, where a
helper struct (`BreakpointKind`) and function
(`std::optional<BreakpointKind> getBreakpointKind(GDBStoppointType
stoppoint_type)`) was created.

[flang][semantics][openacc] Allow collapse clauses on do concurrent (#192488)
This PR generalizes the semantic checking for collapse clauses to work
on `do concurrent` and fixes two bugs exposed along the way:
- The first was that `collapse (n)` where n < the number of nested loops
was giving an assertion violation.
- The second was do concurrent index variables were causing an assertion
violation because they hadn't been declared before looking them up.
The lowering is implemented as a TODO which will happen in a following
diff.

[clang-format] Recognize more braced initializers (#192299)
new
```C++
a = {x * x, x * x};
```
old
```C++
a = {x * x, x *x};
```
Fixes #57442.
The patch makes the program treat a brace following an equal sign a
braced initializer.
The patch changes these tests.
- In UnderstandsSingleLineComments and CommentsInStaticInitializers, the
comment in the formatted code used to be on a separate line, now it is
on the same line as the brace. The new behavior is consistent with
comment in braced lists that are correctly identified. Here is the
code for it from the test LayoutCxx11BraceInitializers and the
function mustBreakBefore.
```C++
// In braced lists, the first comment is always assumed to belong to the
// first element. Thus, it can be moved to the next or previous line as
// appropriate.
verifyFormat("function({// First element:\n"
" 1,\n"
" // Second element:\n"
" 2});",
"function({\n"
" // First element:\n"
" 1,\n"
" // Second element:\n"
" 2});");
if (Right.is(tok::comment)) {
return Left.isNoneOf(BK_BracedInit, TT_CtorInitializerColon) &&
Right.NewlinesBefore > 0 && Right.HasUnescapedNewline;
}
```
- In FormatsBracedListsInColumnLayout, the style is configured to one
which allows a trailing comment in the first line.

[CodeGen] Fix incorrect index in rematerialization tracking (#194387)
When deleting the last rematerialization of a register, we should delete
the rematerializer's remat tracking map's entry that corresponds to the
index of the *original* register, not the rematerialized register.
The existing typo has no impact on correctness at the moment because
entries with rematerialized register indices are never created (so there
is nothing to erase), and having an empty set in a value does not break
any code invariant; it just wastes memory.

[Flang][OpenMP] Allow Fortran BLOCK construct inside WORKSHARE region (#193352)
**Problem**
Flang incorrectly rejects Fortran BLOCK constructs inside OpenMP
WORKSHARE regions. This fixes the semantic check to recursively validate
the contents of BLOCK constructs instead of rejecting them.
The Fortran BLOCK construct (F2008) is a transparent scoping wrapper
that does not affect execution semantics. When a BLOCK appears inside a
WORKSHARE region, the restriction on allowed statements should apply to
the contents of the BLOCK, not the BLOCK construct itself.
**Fix**
The function CheckWorkshareBlockStmts (check-omp-structure.cpp) loops
through each statement inside a WORKSHARE region and checks if it's
allowed.
Before this fix, it only recognized:
```
Assignments, FORALL, WHERE statements
OpenMP constructs (ATOMIC, CRITICAL, PARALLEL)
When it saw a Fortran BLOCK, it didn't recognize it and threw an error.
```
When we see a BLOCK construct, instead of rejecting it, we "look inside"
and check if the statements inside the BLOCK are valid. This is done by
calling the same function recursively on the BLOCK's contents.

[Clang][RAV] Visit components of __builtin_offsetof designators (#194122)
`RecursiveASTVisitor` previously only traversed the type operand of an
`OffsetOfExpr,` ignoring the field/identifier/base/array-index
components of the designator. This meant tools built on RAV (clang-tidy,
clangd, indexers, ...) silently missed every field reference inside
`__builtin_offsetof(T, a.b.c)`.
Add a `TraverseOffsetOfNode / VisitOffsetOfNode` pair following the same
pattern used for `ConceptReference`, `ObjCProtocolLoc`, and friends. The
`DEF_TRAVERSE_STMT` for `OffsetOfExpr` now invokes
`TraverseOffsetOfNode` for each component; array index expressions
continue to be reached via the existing children() traversal. Default
visitation is a no-op, so the change is opt-in for consumers and
behavior-preserving otherwise.
Also expose `OffsetOfNode` as a `DynTypedNode` kind via `ASTTypeTraits`
so that downstream machinery (`SelectionTree`, parent maps, matchers)
can reference these nodes uniformly.
The same gap exists for Designator inside `DesignatedInitExpr` and can
follow this recipe in a follow-up.
Related: https://github.com/llvm/llvm-project/pull/192953. The current
PR enables precise component resolves in clangd (support to be added in
a followup).

[PowerPC] Enable using HwMode for instructions (#191051)
The HwMode is already used for operands representing an effective
address. It can also be used for general purpose registers but this is
not clear from the naming. This change
- introduces the hw-mode dependent register class `GxRC`, and the
associated register operands
- removes register class `ptr_rc_idx_by_hwmode`, and replaces the only
use with `gxrc`
- uses the `EQV` instruction as an example how to use the new class

- Adds the memory size as last operand to the pseudo instruction
- Updates the C++ code to take advantage of the memory size in the

Add support for the f16x8.demote_f32x4_zero instruction. This
instruction converts a v4f32 vector to a v4f16 and pads the result with
zeros to fill the 128-bit register.
This enables efficient lowering of fptrunc operations from v4f32 to
v4f16 when the result is zero-extended or when only the low lanes are
needed. A DAG combine is included to recognize these patterns and fold
them into the new instruction.

`__builtin_frexpf`, `__builtin_modf`, `__builtin_powi`, and related
builtins were incorrectly falling through to the `__builtin_isnan`
handler in `emitBuiltinExpr`, which calls `createBoolToInt` /
`createIsFPClass`. This produced a `cir.cast` with an integer result
type when the actual return type is floating-point, failing CIR
verification.
Break out of the switch so these builtins fall through to the
`isLibFunction()` path, which emits them as regular library calls.

[CIR] Fix eraseOp assertion in TryOp flattening with unreachable handlers (#193615)
When a try block has catch handlers but no throwing calls, the handler
regions are unreachable and the TryOp is erased. However, ops inside the
handler regions may reference values that were inlined from the try body
into the parent block, causing an assertion in `eraseOp` ("expected that
op has no uses").
This drops all defined value uses from handler regions before erasing
the TryOp.

[Clang] Avoid an extra `FunctionPrototypeScope` for lambda trailing requires-clauses (#194068)
`ParseTrailingRequiresClause` currently always creates a synthetic
`FunctionPrototypeScope`. This is needed for ordinary function
declarators
whose prototype scope has already ended, but it is wrong for lambda
trailing
requires-clauses because they are parsed while the lambda prototype
scope is
still active.
The extra counted scope gives parameters in nested requires-expressions
an
incorrect function scope depth. Split the synthetic prototype-scope
setup from
the trailing requires-clause parser so the lambda path can parse the
clause in
the existing prototype scope.

[Offload] Make kernel dynamic memory handling more generic (#194403)
Make sure we do not get unexpected NumThreads and NumBlocks values when

dynamic block memory allocation to handle multi-dimensional blocks.
The DynBlockMem fallback is never used in a non-bare context where
`NumBlocks[1]` and `NumBlocks[2]` are not 1 so the code was correct, but
this patch makes sure that assumption is made explicit, and also
future-proofs the code in case we decide to allow multi-dimensional
blocks for fallback dyn block mem in some path.

[DirectX] Add DXILDebugInfo pass (#191254)
The pass is enabled for DXILBitcodeWriter and ValueEnumerator to
transform LLVM IR and provide data required to lower it to DXIL.
There are 3 ways how DXILDebugInfo pass can change lowering to DXIL:
1. Transform LLVM IR directly in DXILDebugInfoPass::run. This works well
when the target IR does not break any invariants of LLVM IR.
2. Add extra metadata for ValueEnumerator to process with MDExtra map.
When ValueEnumerator enumerates a Key of MDExtra, it also follows the
Value and all its operands.
3. Replace a metadata for ValueEnumerator with a another metadata. When
ValueEnumerator enumerates a Key of MDReplace, or when the writer uses
getMetadataID, the corresponding value of MDReplace map is returned
instead.

Log Message:
-----------
[AsmParser] Revamp how floating-point literals work in LLVM IR. (#190641)
This adds support for the following kinds of formats:
* Hexadecimal literals like 0x1.fp13
* Special values +inf/-inf, +qnan/-qnan
* NaN values with payloads like +nan(0x1)
Additionally, the floating-point hexadecimal format that records the
bitpattern exactly no longer requires the 0xL or 0xK or similar code for
the floating-point type. The current hexadecimal syntax is retained for
the moment, but it is expected to be ripped out after the next release
of LLVM.
These changes were discussed in an RFC at
https://discourse.llvm.org/t/rfc-floating-point-literals-in-llvm-ir/82974.

-----------
[SLP]Bail out on non-schedulable expanded binop with multi-use operand
In tryScheduleBundle's DoesNotRequireScheduling path, an expanded binop
(shl X, 1 modeled as add X, X) doubles the dependency count of the
duplicated operand. Unlike the regular scheduling path, this branch does
not clear stale operand ScheduleData dependencies, so when that operand
has more uses than this bundle member the schedule's decrement count
exceeds calculateDependencies' increment count and UnscheduledDeps goes
negative, hitting "Expected valid number of unscheduled deps".
Fixes #194303.

[lldb] Fix has_lldb_codesign check (#194412)
I met a problem with this test on WSL. WSL has access to Windows's
files. Windows distribution has `security` dir (
`/mnt/c/Windows/security` from WSL point of view). So when we try to run
`security` command we get `PermissionError` instead of
`FileNotFoundError`. It is would not be a problem, but Python firstly
calls decorators for methods (see example below), so we call
`has_lldb_codesign()` not only on Darwin platform. Also I think some
Linux distros might have `security` command, so the current check is not
robust enough.
```python
import unittest
def checker():
raise Exception("test")
@unittest.skipUnless(False, "")
class Tests(unittest.TestCase):
@unittest.skipUnless(checker(), ())
def test():
pass

[MLIR][GPU] Fix async.yield gpu.async.token lowering race (#190717)
Root cause of #170833 (flakiness of `Integration/GPU/CUDA/async.mlir` on
the Tesla T4 mlir-nvidia buildbot).
In `gpu-to-llvm`, two patterns matched `async.yield` with the same
benefit: the structural `ConvertYieldOpTypes` from
`populateAsyncStructuralTypeConversionsAndLegality` (which just retypes
operands), and `ConvertAsyncYieldToGpuRuntimeCallPattern` (which also
creates and records an event on the stream backing each
`gpu.async.token` operand). When the IR contained `gpu.launch_func`, the
dialect-conversion framework picked the structural pattern, silently
dropping the event record. The `async.execute` then yielded a stream
pointer where its consumers expected an event, and the host await ended
up calling `cuEventSynchronize` on a stream pointer. That call returns
an error without waiting, so the host raced against the GPU.
This change implements a fix which registers
`ConvertAsyncYieldToGpuRuntimeCallPattern` with pattern benefit 2 so it
wins on yields carrying `gpu.async.token` operands. The structural
rewriter still handles yields without token operands.
Also adds a new test `lower-async-to-gpu-runtime-calls.mlir` to check
the correct IR shape of `async.yield` after a `gpu.launch_func`.

[analyzer] Fix use-after-free in CheckerContext::getMacroNameOrSpelling (#194174)
This UAF bug was introduced 14 years ago, in 43de767b55c07.
The first use of this API was in
3b754b25bde4914e5ab693e7db9533c3260e926e, roughly around the same era.
It was dormant because the first param of `socket` and friends are
macros, and those didn't trigger this UAF.
I decided to go against adding a test because I figure that would be not
really meaningful.

[flang][cuda] Fix CUFDeviceGlobal duplicate skip and CUFAddConstructor for empty gpu.module (#194290)
**Fix 1:**
```fortran
module m
real, device :: a(3), b(3), c(3)
contains
attributes(global) subroutine kernel()
a(1) = 1.0
end subroutine
end module
```
When a kernel references global `a`, an earlier pass
(`CUFDeviceFuncTransform`) clones it into the `gpu.module`. When
`CUFDeviceGlobal` later processes all device globals, it finds `a`
already exists, and `break` exits the loop — skipping `b` and `c`
entirely.
Fix: Change `break` to `continue` in `CUFDeviceGlobal.cpp`.
**Fix 2:**
```fortran
module kernels_m
real, device :: dev_var
contains
attributes(global) subroutine my_kernel()
end subroutine
end module
program main
use kernels_m
end program
```
When a compilation unit USEs a CUDA module but defines no kernels
itself, the empty `gpu.module` is still registered with the CUDA
runtime, causing `cudaErrorNoKernelImageForDevice`.
Fix: Return early from the constructor if the `gpu.module` has no
kernels. Also skip variable registration for globals not in the
`gpu.module`.

[CIR] Remove overly strict end_catch assertion in catch handler flattening (#193796)
The assertion in `flattenCatchHandler` required `end_catch` to be the

between. Complex catch handlers with cleanup code or nested control flow
can have additional operations between `end_catch` and `yield`. The
yield-to-branch replacement does not depend on `end_catch` position.

controlled globally via the -fmatrix-memory-layout command-line flag
(LangOptions::DefaultMatrixMemoryLayout). This commit adds the parsing
and semantic analysis infrastructure needed to support per-declaration
layout, matching DXC behavior.

[flang][cuda] Include constant extents in cuf.alloc size computation (#194288)
Example:
```fortran

For arrays with mixed constant and dynamic extents
(`!fir.array<?x4x?xf32>`), the allocation size only includes the dynamic
extents (`n * m * 4 bytes`), missing the constant extent `4`. This
under-allocates by a factor of 4, causing `cudaErrorIllegalAddress`.
Fix: After multiplying the dynamic extents, also multiply in constant
extents from the type, producing the correct size (`n * m * 4 * 4
bytes`).

When nowait is combined with reduction, the reduce function argument to
__kmpc_reduce_nowait is passed as null to prevent the runtime from
selecting the tree reduction method for host, which carries a barrier.

[clang-tidy][readability-identifier-length] add structured bindings support (#193838)
This change extends the `readability-identifier-length` check to structured
binding declarations. Currently, only the names of regular variables,
function parameters, exceptions variables in catch blocks and loop
variables are checked. In other words, `int a = ...` warns but `auto [a]
= ...` does not.
This change enables the check to warn when the length of the names
introduced in structured bindings declarations is too short, following
the same rules as for the other kinds of declarations. Two new options
are introduced:
- `MinimumBindingNameLength` defines the number of characters below
which a warning is issued (the default it set to 2, like for loop
variables and exceptions variables)
- `IgnoredBindingNames` defines the names for which warnings should not
issued (by default, `_` is the only allowed exception)
To implement this feature, a new matcher is registered which matches all
the individual binding names. For example, in `auto [x, y] = ...`, it
matches `x` and `y` separately and the logic for determining if a
warning should be issued is applied independently to each binding name
introduced. Unlike the other matchers which return `VarDecl` nodes, this
new matcher returns `BindingDecl` nodes. The `utils::allDeclRefExpr`
helper function is modified to work for any `ValueDecl` node (the
closest common ancestor of `VarDecl` and `BindingDecl`) in order for the
line count threshold feature to work with this extension.

Allow DIBasicType (and others) to have a scope and location (#190217)
DIBasicType derives from DIType and so it already has slots to store the
scope and location of the type. However, the DIBasicType constructor
(and corresponding DIBuilder method) does not expose this, presumably
because it is not needed by C or C++.
In Ada it is more common to create one's own basic type. So, for Ada
exposing this functionality would be handy.
This patch adds a new overload of DIBuilder::createBasicType to allow
this. Because only Ada uses fixed point types, the patch simply updates
these DIBuilder methods unconditionally.
Note that DwarfUnit already handles this scenario and so no changes were
needed there.

[Clang] Emit LLVM flatten attribute instead of per-callsite alwaysinline (#188615)
Follow-up to #174899 which added the flatten function attribute to LLVM
IR and implemented recursive inlining in the `AlwaysInliner` pass.
This patch updates Clang to emit the LLVM flatten attribute on functions
with `__attribute__((flatten))`, instead of the previous approach of
marking each call site with `alwaysinline`. This completes the
transition to matching GCC's flatten semantics.
Changes:
- Remove the callsite `alwaysinline` annotation logic from CGCall.cpp
- Emit the flatten function attribute in CodeGenModule.cpp
- Update clang/test/CodeGen/flatten.c to reflect the new IR output
- Update clang/test/CodeGen/AArch64/sme-inline-callees-streaming-attrs.c
to reflect the new behavior
- Add release notes documenting the behavior change

[SLP]Use VF for build-vector slice size when GatheredScalars were resized
After ExtractShuffles processing resizes GatheredScalars to VF and

and partitions it according to the post-resize NumParts. The previous
SliceSize formula based on E->Scalars.size() no longer matches that
layout and triggers an out-of-bounds ArrayRef::slice while iterating
gather-shuffle entries. Use getPartNumElems(VF, NumParts) by default;
fall back to the original-scalars formula only when
Mask.size() == E->Scalars.size() (no resize happened).

thread_local variables at function scope work very much like
static-locals, except with slightly different lowering from
cir-lowering-prepare. This patch implements that lowering. Global tls
variables are left to a later patch.
One decision I made here was that LocalInitOp lost its
'static-local'-ness, and assumes it is always static-local. Global TLS
is probably just going to use Global directly, so we don't need to to
permit it.
I DID leave it in the printing, as it makes it more clear what is
happening/for symmetry with get_global/global.

fix preserve_none in X86 backend (#192300)
This is a bug in the X86 backend affecting preserve_none with -O1. At
-O1, clang emits:
```
tail call preserve_nonecc void @_Z14func(ptr noundef nonnull byval(%struct.S) align 8 %1)
```
The `preserve_none` + `byval` never emitted the required caller-side
copy of the pointee. The callee received a pointer directly to the
original memory, violating the byval contract from LangRef: "a hidden
copy of the pointee is made between the caller and the callee, so the
callee is unable to modify the value in the caller".
The root cause is that CC_X86_64_Preserve_None in X86CallingConv.td had
no byval handling. As a result, byval arguments were falling through to
the register assignment rules and being assigned to registers instead of
stack slots.
The bug is fixed by one line in CC_X86_64_Preserve_None:
```
CCIfByVal<CCPassByVal<8, 8>>,
```
This ensures byval arguments are assigned to stack slots before the
register assignment rules are considered, consistent with all other
x86-64 calling conventions.

[CodeGen] Change -O0 bool load codegen to have nonzero model (#193783)
The main follow-up item to
https://github.com/llvm/llvm-project/pull/160790 was changing -O0
codegen to convert in-memory i8 bool values to i1 with the `nonzero`
rule (`icmp ne i8 %val, 0`) rather than the `truncate` rule (`trunc i8
%val to i1`).
Bool values can only be `true` or `false`. While they are notionally a
single bit, the smallest addressable unit is CHAR_BIT bits large, and
CHAR_BIT is typically 8. Programming errors (such as memcpying a random
byte to a `bool`) can cause the 8-bit storage for a `bool` value to have
a bit pattern that is different from `true` or `false`, which then leads
to undefined behavior.
Clang has historically taken advantage of this in optimized builds
(everything other than -O0) by attaching range metadata to `bool` loads
to assume that the value loaded can only be 0 or 1. This leads to
exploitable security issues, and the correct behavior is not always easy
to explain to C developers. To remedy this situation, Clang accepted a
[-fstrict-bool](https://discourse.llvm.org/t/defining-what-happens-when-a-bool-isn-t-0-or-1/86778)
switch to control whether it can assume that loaded bool values are
always necessarily 0 or 1. By default, it does (maintaining the status
quo), and users must specify `-fno-strict-bool` to opt out of that
behavior.
When opting out, users can optionally request that bool i8 values are
converted to i1 either by truncation or by comparing to 0. The default
is comparing to 0. However, since `-O0` alone _technically_ uses
-fstrict-bool, unoptimized builds convert i8 bool values to i1 with a
`trunc` operation, whereas `-O1 -fno-strict-bool` converts i8 bool
values to i1 with `icmp ne 0`. This is a surprising inconsistency.
This PR changes -O0 codegen to align with -fno-strict-bool. This is
achieved with a single-line change:
```
bool isConvertingBoolWithCmp0() const {
switch (getLoadBoolFromMem()) {
case BoolFromMem::Strict:
+ return !isOptimizedBuild();
case BoolFromMem::Truncate:
```
However, it impacts a _very large_ number of tests, so we agreed to move
it out of the -fstrict-bool PR to reduce the chances we would have to
back out the whole thing for this secondary item.
This PR does the change and modifies the tests accordingly. I expect
that it will go stale rather quickly. If this needs more discussion,
I'll only update it once we reach consensus.

[Sema] Enforce parameter match for ownership_returns attribute (#192339)
Previously parsing multiple ownership_returns attributes with different
arguments could lead to a crash. The documentation states that if
forward declarations have ownership_returns, they must have the same
arguments, and it may appear at most once per declaration.
This patch ensures that if multiple ownership_returns attributes are
present, their arguments (identifier and the optional index) must
exactly match. The diagonstic err_ownership_param_mismatch is introduced
for clarity.
Test cases for f15, C::f, and the newly added f22 were also updated to
match the requirement that all declarations of ownership_returns have
the same arguments, using the err_ownership_param_mismatch diagonstic.

[NVPTX] Add reverseBranchCondition and CBranch inverted flag (#191889)
Add flag to `CBranch` instruction for inverted predicate branches (`@!p
bra`) and implement `reverseBranchCondition` to support branch condition
inversion.
This enables passes like branch folding to properly reverse branch
conditions, and is a prerequisite for SETP predicate inversion CSE.

without the need of constructing VPCostContext.

[CIR] Eliminate SymbolTable::lookupSymbolIn hotspots (#193362)
mlir::SymbolTable::lookupSymbolIn is O(n) per lookup, so cumulative
symbol lookups during CIRGen are O(n^2) in the number of global symbols.
On template-heavy translation units this becomes a significant
compile-time hotspot.
Replace the SymbolTable lookup path with a per-CIRGenModule DenseMap
cache keyed by symbol name, giving O(1) lookups.
On a synthetic template-heavy stress test, end-to-end compile time on
`clang -fclangir -S -emit-llvm -O0` improves by ~11% on a 33K-LOC input
(5.86s -> 5.21s) and ~16% on a 67K-LOC input (16.09s -> 13.52s). The
super-linear growth of the win with input size confirms the O(n^2) ->
O(n) effect.
Similar to previous compile time fix, repro shape (scale records and
template instantiations into the hundreds/thousands to amplify):
template <typename T, int N> struct Box { T head; Box<T, N-1> tail; };
template <typename T> struct Box<T, 0> { T head; };
struct R0; struct R1;
struct R0 { int v; Box<int, 4> b; R1* next; };
struct R1 { long v; Box<long, 4> b; R0* next; };
int f0(R0*); int f1(R1*);
int f0(R0* r) { return r->v + (r->next ? f1(r->next) : 0); }
int f1(R1* r) { return (int)r->v + (r->next ? f0(r->next) : 0); }

[Offload][libsycl][clang-sycl-linker] Simplify SYCL Offload wrapping (#193876)
Replace the __sycl_tgt_bin_desc/__sycl_tgt_device_image-based fat binary
registration with a simpler OffloadBinary-native approach:
- __sycl_register_lib/__sycl_unregister_lib now take (BinaryStart, Size)
instead of a __sycl_tgt_bin_desc pointer; __sycl_unregister_lib only
needs BinaryStart since the runtime looks up the binary by its start
address.
- OffloadWrapper's SYCL wrapping is significantly simplified: the
__tgt_bin_desc/__tgt_device_image structs and the descriptor
construction code are replaced by a single embedded OffloadBinary blob
passed directly to the register/unregister entry points.
- clang-sycl-linker generates a single OffloadBinary, which contains
multiple images.
- ProgramAndKernelManager::registerFatBin parses the blob via
OffloadBinary::create, keying MDeviceImageManagers by BinaryStart to
eliminate the reparse on unregister.
- DeviceImageManager owns std::unique_ptr<OffloadBinary> instead of
borrowing a __sycl_tgt_device_image pointer; getRawData renamed to
getOffloadBinary.
- Introduce forEachSymbol and SymbolTable serialization
(writeSymbolTable/ SymbolTableHeader/SymbolTableEntry) in Utility.h to
expose the kernel symbol table embedded in the OffloadBinary "symbols"
section for consumption by the SYCL runtime.
- device_binary_structures.hpp reduced to DeviceBinaryTripleSPIRV64.

[lldb] Unify python shebangs (#187257)
As per PEP-0394[1], there is no real concensus over what binary names
Python has, specifically 'python' could be Python 3, Python 2, or not
exist.
However, everyone has a python3 interpreter and the scripts are all
written for Python 3. Unify the shebangs so that the ~50% of shebangs
that use python now use python3.

ec9d7d18bdfe21c30c94c02f14f3613f7b69a17b (#194087) due to bot failures
on ppc64le and Windows.
This reland incorporates the following fixes:
1) Rename member variable InputFile to InputFilePath inside struct
InputFile to resolve MSVC shadow
conflicts.
2) Add arm-registered-target to ETM tests REQUIRES directive to prevent
failures on builders that do
not have the ARM target enabled.

lldb] Fix two issues causing TestEvents.py flakiness (#194438)
This PR fixes two issues that contribute to `TestEvents.py` being flaky
in CI:
1. `ProcessEventData::DoOnRemoval` runs the full stop-handling logic
(like `ShouldStop` and `RunStopHooks`) every time an event is consumed
from any listener. When the primary listener consumes an event and then
the shadow listener consumes the same event, the logic runs twice. The
second execution can race with subsequent event processing. Fix this by
incrementing `m_update_state` after the first successful run so
secondary listeners skip the full logic.
2. Target::RunStopHooks updates `m_latest_stop_hook_id` (marking a stop
as "handled") before checking whether any threads have stop reasons. If
the check fails and hooks don't run, the stop ID is already consumed,
preventing hooks from ever running for that stop. Fix this by deferring
the update until we're certain we'll actually run hooks.

PR #181446 ("[asan] API for getting multiple pointer ranges") added five

asan_abi_tbd.txt
or implementing them in compiler-rt/lib/asan_abi/asan_abi.cpp. This
broke
the AddressSanitizerABI-arm64-darwin ::

the
symbols actually exported by libclang_rt.asan_abi_osx.a.
List the new symbols alongside the existing __asan_get_report_* entries
so the stable-ABI test passes. The symbols remain unimplemented in the
stable ABI library; this change only reflects that they are
intentionally
not part of the stable ABI surface.

[InlineSpiller] Fix live-range update in hoisting within bb (#193880)
The InlineSpiller tries to shorten the live-ranges used when storing a
value that is defined by a sibling register by performing the following
transformation:
```
a = copy b
store a
```
=>
```
store b
```
That is, it eliminates the copy and store the original value at the copy
location.
As far as `b`'s live-range is concerned, this transformation is neutral
as long as the store is inserted in place of the copy being removed.
That doesn't hold when the copy is part of the basic block prologue. In
that case, the earliest insertion point for the store is after the
prologue:
```
a = copy b # part of bb prologue
... # more prologue instrs
store a <-- earliest insertion point
```
Therefore when this optimization kicks in and the copy is in the bb's
prologue, b's live-range needs to be extended to that insertion point.
This is exactly what this fix does.
Note: This issue is fairly easy to understand from an IR stand point and
one would expect a small reproducer.
Indeed, we would need only something that looks like:
```
a = copy b # prologue compatible copy
... # some more prologue instrs
... # high pressure point
= use a
```
The problem is the InlineSpiller optimization (implemented in
InlineSpiller::hoistSpillInsideBB) triggers only if `a` and `b` are
sibling registers, meaning they are the product of a live-range
splitting. Controlling live-range splitting is hard and I couldn't come
up with a smaller test case. The problem also disappears if we run
greedy alone because the live-ranges are repacked (well the slot indices
to be exact) compared to what the scheduler produces. That changes the
allocation order and the bug is not hit anymore.
The alternative would be to run the pipeline from the
coalescer/scheduler but that's not a whole lot more robust than the LLVM
IR path, plus the reproducer would be ~20k line long!
The other option (maybe something we should do in the long term) would
be to serialize/deserialize the VirtRegMap object so that we can set the
Virt2SplitMap map in a state that register a and b as siblings.

[CIR] Handle DeclRefExpr's to NTTP Objects (#194482)
NTTP objects are represented as globals so that you can refer to
them/address of them/etc, but most access to them should result in
constant expressions. This patch implements the creation of these
globals, and allows compelation to continue.
This should fix up the last DeclRefExpr LValue that appears other than
MSGuids and named global registers, both of which are specific to
individual attributes.

Reland "[clang][modules-driver] Add support for C++ named modules and import std" (2nd attempt) (#194475)
This reverts #193857 and relands #193312.
This adds basic support for explicit C++ named module builds, managed
natively by the Clang driver, including support for use of the Standard
library modules. This follows #187606, which adds the same for Clang
modules.
Current limitations:
- Standard library modules are still compiled to object files instead of
using the provided shared library. (This will be addressed in a
follow-up soon.)
- Caching is not supported yet (but likely to be added during the
upcoming GSoC cycle).
- Importing C++ standard library modules into Clang modules is not
supported (and not expected in the near term).

See
https://github.com/llvm/llvm-project/pull/194475#issuecomment-4331347690.
This constrains the test to not run on aarch64, where it fails on
`clang-aarch64-quick` and `llvm-clang-aarch64-darwin` builders.
The failing builders don't show any output, and the test will be
re-enabled for aarch64 in a later follow-up.

[RISCV] Improve getInterleavedMemoryOpCost for interleave groups with tail gaps. (#192074)
For interleaved access groups where gaps are only at the tail (i.e.
members are contiguous starting from index 0 but do not fill the entire
factor), the interleaved memory access pass can lower them to
vlsseg/vssseg intrinsics with NF equal to the number of group members
rather than the factor after #151612 and #154647.
Previously these groups fell through to the generic fixed-vector shuffle
cost model. This patch adds a dedicated cost path that checks legality
and estimates appropriate cost for them.
TODO: Support scalable vector type.

[CIR] Implement PredefinedExpr in aggregate emitter and add consteval… (#194484)
… aggregate test
Handle PredefinedExpr by delegating to emitAggLoadOfLValue, removing the
NYI fallback. Also add a test for ConstantExpr aggregate emission
(consteval functions returning structs), which was already implemented
but lacked test coverage.
This unblocks ~206 libcxx test failures that involve aggregate
ConstantExpr and PredefinedExpr.
Note on LLVM IR divergence (will be addressed in follow-up PRs): For
consteval functions returning aggregates, CIR currently emits a global
constant + cir.copy that lowers to llvm.memcpy from the global, while
OGCG decomposes the constant into per-field stores. The added CIR / LLVM
/ OGCG CHECK lines in consteval-aggregate.cpp document this difference.
Convergence will come from a follow-up that decomposes the consteval
aggregate stores into per-field stores in LoweringPrepare (and related
GEP-index handling for padded structs).

Added layout_a_scale and layout_b_scale attributes to DpasMx op
Removed AllElementTypesMatch<["a", "b"]> trait to allow different types
for A/B with scales
2. Layout Infrastructure
setupDpasMxLayout(): Creates anchor layouts for all 5 operands (A, B,
C/D, scale_a, scale_b)
Derives scale layouts from parent matrix layouts by dividing innermost
dimension
Supports all layout kinds: Subgroup, InstData, Lane
Fix a bug in getupDpasSubgroupLayouts(): sg_data of A/B matrix should
keep the full K dimension.
3. Layout Propagation
visitDpasMxOp(): Propagates layout attributes from op to operands during
dataflow analysis

[clang][bytecode] Rework APValue visiting (#194408)
First, we can't just ignore the LValuePath of an lvalue APValue. Add
code to handle that and a test case exercising the newly added code.
We also didn't look at APValue bases when initializing from an APValue.

[InstCombine] Reland #165975: Fix #163110: Support peeling off matching shifts from icmp operands via canEvaluateShifted (#190918)
This relanding of #165975 fixes the bug that caused the bootstrap-asan
buildbot failure
(https://lab.llvm.org/buildbot/#/builders/52/builds/16329).
## Original optimization
Consider a pattern like: `icmp (shl nsw/nuw X, L), (add nsw/nuw (shl
nsw/nuw Y, L), K)`
When K is a multiple of 2^L, this can be simplified to: `icmp X, (add
nsw/nuw Y, K >> L)`
This patch extends `canEvaluateShifted` to support `Instruction::Add`
and refactors its signature to accept a `ShiftSemantics` enum (`Lossy` /
`Unsigned` / `Signed`) instead of a bare opcode. This allows the
function to enforce losslessness requirements according to the overflow
flags (nsw/nuw) of the operands. The logic is wired into
`foldICmpCommutative` to fold `icmp (shl nuw/nsw X, C), Op1` into `icmp
X, (Op1 >> C)` when Op1 can be right-shifted losslessly by C bits.
## Bug fixed since #165975
`canEvaluateShiftedShift` unconditionally returned `true` for
same-direction logical shifts, ignoring the `ShiftSemantics` parameter.
This caused `foldICmpCommutative` to incorrectly transform:
`icmp uge (shl nuw X, 4), (lshr Y, 1) → icmp uge X, (lshr Y, 5) ← WRONG`
**Fix:** `canEvaluateShiftedShift` now returns `true` for same-direction
shifts only when `Semantics == ShiftSemantics::Lossy`, blocking the
unsafe fold for `Unsigned`/`Signed` semantics. Regression test added in
`Transforms/InstCombine/icmp_shl_lshr_fold.ll`.

[AArch64][SelectionDAG] Generate subs+csel for usub.sat (#193203)
Fixes https://github.com/llvm/llvm-project/issues/191488
As this is a regression of
https://github.com/llvm/llvm-project/pull/170076, adds a check to avoid
generic lowering of usub.sat to X - zext(X != 0) in case of aarch64 by
making the constraint of this transformation stricter via an extra
isOperationLegalOrCustom guard on USUBO_CARRY. All other backends will
still receive generic lowering as implemented in the original patch.

[Flang][OpenMP] Clear close on descriptor members for box parents in USM (#194287)
Extend the MapInfoFinalization walk introduced in #185330 so
parent/member close consistency is enforced whenever
unified_shared_memory is in effect, not only when the parent map's
variable is a fir.RecordType. Allocatable (box) roots expand to member
maps the same way as derived-type instances; getDescriptorMapType may
add OMP_MAP_CLOSE to implicit descriptor members while the parent map
does not set close, which led to bad device behavior under
-fopenmp-force-usm with multiple mapped allocatables.

When the "IgnoredRegex" option is not set, `IgnoredRegexString` is
default-constructed, i.e. initialized with a null data pointer. This is
passed to `llvm_regcomp` as the pattern argument, causing a nullptr+0 UB
in regcomp.c (caught by UBSan). Fix by initializing
`IgnoredRegexString` with an empty string literal instead.

[mlir][tosa] Make tosa-attach-target optional in addTosaToLinalgPasses (#193467)
addTosaToLinalgPasses unconditionally scheduled tosa-attach-target, thus
adding a `tosa.target_env` attribute to the module. Callers therefore
had no way to opt out of such attribute. This attribute is consumed if
validationOptions is enabled, which is optional. Therefore, if the
caller disables validationOptions, the tosa-attach-target attribute will
exist even after TosaToLinalg. So consumers that don't load the TOSA
dialect can't even parse the resulting module.
This PR makes sure that we schedule tosa-attach-target only when the
caller actually needs it, i.e. when validationOptions or
attachTargetOptions is set. The default values stay inside the
`!attachTargetOptions` branch so callers that set validationOptions
still get a target env to validate against, preserving existing
behavior.
Also add a `validation` pipeline option (default `true`) to the
registered `tosa-to-linalg-pipeline`, so it can be invoked without
scheduling either `tosa-attach-target` / `tosa-validate`. A lit test is
also added.

[LangRef][AMDGPU] Specify that syncscope can cause atomic operations to race (#189015)
Targets should be able to specify that the syncscope of atomic operations
influences whether they participate in data races with each other.
For example, in AMDGPU, we want (and already implement) the load in the
following case to be in a data race (i.e., return `undef` according to the
current definition), because there is an atomic store with workgroup syncscope
executing in a different workgroup:
```
; workgroup 0:
store atomic i32 1, ptr %p syncscope("workgroup") monotonic, align 4
; workgroup 1:
store atomic i32 2, ptr %p syncscope("workgroup") monotonic, align 4
load atomic i32, ptr %p syncscope("workgroup") monotonic, align 4
```
This is consistent with the behavior of, e.g., [heterogeneous-race-free (HRF)
memory models](https://research.cs.wisc.edu/multifacet/papers/asplos14_hrf.pdf) and the [HSA memory model](https://hsafoundation.com/standards/).

[X86] lock opt ptr const inconsistencies (#185195)
Resolves: https://github.com/llvm/llvm-project/issues/147280
The linked issue mentions cases of atomic arithmetic followed by a test
which can be recovered by flags that are emitting cas loops instead of
lock + op which can be inferred from flags.
There's one fold that solves the issue's code: `lock and` sets ZF on the
result of old & C, so any nonzero comparison against new = old & C can
be answered with ZF, so this fold does just that, reduces to a != 0 or
== 0.
I also decided to refactor `shouldExpandCmpArithRMWInIR` into a
dispatching function and make `getCmpArithCC` just return X86::CondCodes
directly. This deleted the dispatching switch later in the code.
Also I broke out the different cases of `getCmpArithWithCC` into helper
functions for each case (add, sub, and, xor, or, add with overflow, sub
with overflow) and turned them guard clause style to reduce nesting
since the original `getCmpArithWithCC` had everything in a nested
function which was hard to read. The functions are named so it's
straightforward to add new cases or move them around as desired.

[flang] improve array section analysis for WHERE (#194399)
The array section analysis in the HLFIR pass in charge of WHERE lowering
was unable to tell that the LHS and RHS are the same array section when
the base is an assumed shape or when a variable is used as indices.
This patch adds an optional callback to the array section
analysis to tell if two SSA values have the same value. This call back
is then implemented to tell that two SSA values are the same only if:
they are the result of equivalent operations with no memory effect (ok
to be non speculatable) and with operands that have the same value
(recursively), or if they are the load from the same variable (which is
OK in the context of WHERE RHS/LHS thanks to Fortran 2023 10.1.4 that
guarantee that a variable referred both on the RHS and LHS cannot be
modified by side effects in the RHS/LHS).

[AArch64][GlobalISel] Lower BF16 FPTRUNC (#193941)
When the architecture +bf16 features is available this is simple as we
lower to a standard instruction. When not available we need to expand to
a series of instructions that performs the necessary rounding. The code
to do that is a port of TargetLowering::expandFP_ROUND to GISel, minus
the float64 odd rounding via expandRoundInexactToOdd. f64 will follow in
a followup patch.
uitofp and sitofp are currently disabled, so that we can take this one
step at a time and check each part in turn. The LLT fp types attempt to
return true for ieee types without UseExtended for types of the correct
size, always returning false for non-standard types.

[InstCombine] Combine llvm.sin/llvm.cos libcall pairs into llvm.sincos (#184760)
Teach InstCombine to recognize pairs of `llvm.sin(x)` and `llvm.cos(x)`
intrinsic calls that share the same argument and replace them with a
single `llvm.sincos(x)` call, extracting the individual results.
The optimization works in two phases:
1. **SimplifyLibCalls**: Convert `sin`/`cos` C library calls (e.g.
`sinf`, `cosf`, `sin`, `cos`, `sinl`, `cosl`) into `llvm.sin` /
`llvm.cos` intrinsics when the call does not access memory (i.e. does
not set `errno`). This normalization step brings library calls into
the same form as compiler-generated intrinsics.
2. **InstCombineCalls**: When visiting an `llvm.sin` or `llvm.cos`
intrinsic, scan the users of the shared argument for a matching
counterpart. If found, emit a single `llvm.sincos` call placed right
after the argument definition, replace both original calls, and erase
the matched instruction.
Also remove the completed sincos TODO from Target/README.txt.

from:
* clang/test/CodeGen/AArch64/neon_intrinsics.c
to:
* clang/test/CodeGen/AArch64/neon/intrinsics.c
The lowering follows the existing implementation in
CodeGen/TargetBuiltins/ARM.cpp.

[Clang][AArch64] Fix codegen for SVE vector compare operations (#194013)
Overloaded operartors `<`, `>`, `<=`, `>=`, `==`, and `!=` with SVE
integer vector operands emitted LLVM IR with a couple of issues:
* The `icmp` instruction always performed unsigned comparison, even for
signed operands.
* The result of the comparison was zero-extended, whereas the intent is
to follow established NEON conventions and sign-extend it.
This patches fixes these issues.

[clang][test] Fix test failures when LLVM_WINDOWS_PREFER_FORWARD_SLASH is ON (#193156)
This commit addresses several test failures in Clang that occur on
Windows when
the CMake option -DLLVM_WINDOWS_PREFER_FORWARD_SLASH=ON is enabled.
Key changes:
- unit tests: Normalized expected paths to native style using
llvm::sys::path::native
(Basic/FileManagerTest, Frontend/ReparseWorkingDirTest) or updated
diagnostic matching
to be separator-agnostic (Driver/ToolChainTest).
- regression tests: Updated FileCheck patterns to use flexible regex
{{[/\\\\]}} or
{{[/\\\\]+}} to match both path separator styles.
- absolute-paths-windows.test: Skipped when forward slashes are
preferred because
mklink does not support forward slashes in directory paths and
interprets them
as command-line switches. Added 'windows-prefer-forward-slash' lit
feature.

[AsmPrinter][debug] Materialize abstract lexical blocks referenced by global vars (#193986)
After 63074da2 moved global variable emission from beginModule() to
endModule(), getOrCreateContextDIE() is called after abstract scope DIEs
have been built. However, skipLexicalScope() may have elided an abstract
lexical block that has no local variables. When a global variable (e.g.,
a function-scope static) is scoped to such a block,
getOrCreateContextDIE() returns nullptr causing an assertion. This PR
keeps abstract lexical blocks when they are the scope target of a global
variable in the compile unit.
Derived via LLM usage.

[NFC][analyzer] Refactor Environment to map Expr to SVal instead of Stmt to SVal (#193295)
Previously the `Environment` mapped `{Stmt *, LocationContext}` pairs to
symbolic values; but semantically it represents the values produced by
the evaluation of _expressions_, so there was no good reason to use
non-`Expr` statements in this mapping.
This commit replaces `Stmt` with `Expr` (its subclass) in this mapping
to accurately represent the actually relevant type.
This change is also propagated to methods, variables etc. that handle
the `Environment`.
There was a special case in `Environment::getSVal` that allowed looking
up a `ReturnStmt` in the `Environment` (and translated this to a lookup
of the "return value" sub-expression of the `ReturnStmt`). This commit
eliminates this and modifies the callers to explicitly look up the
sub-expression of the `ReturnStmt`.

[LoongArch] Support VBIT{CLR,SET,REV}I patterns for non-native element sizes (#193719)
Extend vsplat_uimm_{pow2,inv_pow2} matching to allow specifying an
explicit element bit width, enabling recognition of splat patterns whose
logical element size differs from the vector's native element type.
Introduce templated selectVSplatUimm{Pow2,InvPow2} helpers with an
optional EltSize parameter, and add corresponding ComplexPattern
definitions for i8/i16/i32 element widths. This allows TableGen patterns
to match cases such as operating on v8i32/v4i64 vectors with masks
derived from smaller element sizes.
With these changes, AND/OR/XOR operations using inverse power-of-two or
power-of-two splat masks are now correctly selected to VBITCLRI,
VBITSETI, and VBITREVI instructions instead of falling back to vector
logical operations with materialized constants.

```c++
struct R {
struct Inner { constexpr int f() const { return 0; } };
int a = b.f();
Inner b;

constexpr R r;
```
because the life time was started by default.
This patch makes record members be `Lifetime::NotStarted` by default
(unless they are primitive arrays) and then starts the lifetime when in
`Pointer::initialize()`.

[flang] allow rebox/embox of OPTIONAL (#194319)
Delay materialization of branches when building local temporary
descriptor for OPTIONAL from hlfir-to-fir until pre-cg-rewrite.
This makes the IR easier to analyze with OPTIONAL (for instance alias
analysis does not need to handle the branches to find the source).
This is done by adding an "optional" attribute to fir.embox, fir.rebox,
and fir.rebox_assumed_rank to indicate that their cogeneration must be
conditional.
The conditional aspect is implemented in pre-cg-rewrite to avoid
complexifying codegen and the fir.cg dialect.

[SPIR-V] Matrix in struct pointer legalization (#193073)
When looking to load an object at the start of a struct, the types do
not always match exactly. When we have an HLSL matrix the type in the
load will not match the type in memory. We need to improve the pointer
legalization pass to look for any "compatible" type at the start of an
aggragate.
A compatible are two types that the pass knows know to convert from one
to another.
This involves a refactoring of the code to make the check more general.

[SLP][NFC]Cache IsExternallyUsed by Value in cost computation
Same V is commonly seen in multiple TEs (shared scalars), and the

match() pattern checks plus per-user getTreeEntries lookups - all
V-only-dependent. Split out the V-dependent body and memoize by
Value pointer, leaving the TE-specific copyable check at the call
site. DeletedNodes is read-only during the cost loop, so caching
is safe.

[Lit] Change processRedirects to open all files in binary mode (#194368)
This PR is the second in a series of patches upgrading Lit's in-process
built-ins to be able to run with piped input/output and full redirection
support, and to allow custom in-process builtns to be provided via the
Lit config. The remaining patches to Lit's test runner can be found here@
https://github.com/BStott6/llvm-project/compare/lit-inproc-builtins.
This is part of the Lit daemonized testing project:
https://discourse.llvm.org/t/88612.
This PR makes Lit's `processRedirects` function open all input/output
files in binary mode. This makes sure that in-process builtins have the
expected behaviour when reading and writing from them:
Newline translation is not required for any of the current in-process
built-ins, in fact, the in-process built-in for `echo`, which is the
only one that writes to `stdout`, explicitly re-opens the output file
with `newline=""` on Windows, to avoid newline translation. Also,
in-process builtins will eventually need to be able to read or write
binary data: for example, `opt` without `-S` running in daemon mode.
I believe this has no functional change for regular process invocations;
I have confirmed that programs invoked by Lit which write to files
opened in binary mode by Lit still have the newline translation
performed as normal on Windows, unless they change the mode of their
output stream themselves.

conversion to treat these as compound names, keep the old spellings as
deprecated aliases, and emit a warning when deprecated spellings are
used.

[Lit] Open sub-processes with text=`False` (#194577)
This PR is part of a series of patches upgrading Lit's in-process
built-ins to be able to run with piped input/output and full redirection
support, and to allow custom in-process builtns to be provided via the
Lit config. The remaining patches to Lit's test runner can be found here:
https://github.com/BStott6/llvm-project/compare/lit-inproc-builtins.
This is part of the Lit daemonized testing project:
https://discourse.llvm.org/t/88612
This PR makes Lit open all sub-processes with `text=False`, so that the
Python code will be able to read and write binary data to and from their
IO streams. This currently causes no functional change, as when Lit
reads output from the sub-processes, it already handles the case that
the read output is `bytes` by decoding it, but we will need to be able
to read binary data from a sub-process's STDIN if its output, which may
be binary, is piped into an in-process built-in, and we will need to be
able to write binary data to a sub-process's STDOUT if its input is
piped from an in-process builtin.
I have made sure that on Windows, when a sub-process invoked by Lit has
its output redirected to a file by Lit, the `\n -> \r\n` conversion is
performed as usual when writing to the file from the process - this
change only affects how the Python code interacts with the streams.

[flang][cuda] Preserve fir.rebox captured by cuf.kernel via CUDAKernelOpInterface (#193890)
Reland of #193837 (reverted in #193855), now using a marker op interface
to avoid the link cycle that broke `BUILD_SHARED_LIBS=ON` builds.
`SimplifyArrayCoorOp` folded `fir.rebox` into `fir.array_coor` across a
`cuf.kernel` boundary. CUF lowering needs the captured rebox to
materialize a managed-memory descriptor for the kernel; folding it away
makes the kernel dereference the host-side descriptor and crash with
`cudaErrorIllegalAddress`.
Fix is to add `fir::CUDAKernelOpInterface`, a marker op interface
defined in FIRDialect and implemented by `cuf.kernel`. The
canonicalization guard queries the interface, so the `TypeIDResolver`
symbol lives in `libFIRDialect.so` and no `FIR -> CUF` link edge is
introduced.

[OpenMPIRBuilder] Cast device num_threads to i32 for __kmpc_parallel_60 (#194634)
I observed a crash in device OpenMP lowering when compiling with
`-fdefault-integer-8`. In `targetParallelCallback`, `NumThreads` can be
`i64`, but `__kmpc_parallel_60` expects an `i32` `num_threads`
parameter, which caused a bad-signature assertion during call creation.
The fix is to use `CreateZExtOrTrunc(..., Int32)` for the `num_threads`
argument before building the runtime call. This matches the handling
used in clang in `CGOpenMPRuntimeGPU::emitParallelCall`.
The problem can be seen with the following testcase whe compiled with
`flang -fopenmp --offload-arch=gfx90a test.f90 -fdefault-integer-8``
```
program test
implicit none
integer :: nthreads
integer :: i
nthreads = 137
!$omp target teams distribute parallel do num_threads(nthreads)
do i = 1, 1
end do
!$omp end target teams distribute parallel do

A variant of https://github.com/llvm/llvm-project/pull/176253 with a
change to reduce compile-time impact.
Since "llvm_unreachable" is actually allowed in constexpr functions,
simply emit the bodies of the selected functions in the header file.
In the previous PR the `isAllowedClauseForDirective` function was made
constexpr, but since it was very long it had a significant impact on
compilation time. In this PR that function is no longer constexpr.

[LLVM] Disable IO sandbox in symbolizeAddresses (#194597)
The function `symbolizeAddresses` is used by debugify to symbolize
addresses captured in the current invocation of LLVM, which it does by
executing llvm-symbolizer with temporary input and output files.
Creating the temporary files has an explicit sandbox exclusion, as
temporary files are necessarily not part of the compiler's formal
output, but attempting to read back the output file via MemoryBuffer
triggers a sandbox violation. Since we are always only operating on
temporary files within symbolizeAddresses, this patch disables the IO
sandbox in that function.

[HIP][MacOS] Mach-O support and Darwin toolchain fixes (#183991)
This PR adds support for HIP on macOS: Mach-O section naming, Darwin
host toolchain initialization guards, and HIPSPV behavior when Darwin is
the host.
This has been verified using chipStar on MacOS via the PoCL OpenCL
implementation.
## Uninitialized target workaround
Darwin’s toolchain is only initialized when its own TranslateArgs runs.
For HIP/CUDA device jobs, Darwin is used as the HostTC and never gets
its args translated, so its target stays uninitialized. The new checks
avoid asserting on that uninitialized state. A better long-term fix is
to initialize Darwin earlier (see the FIXME in Driver.cpp
BuildJobsForAction).
- [ ] Initialize Darwin toolchain during construction instead of lazily
in TranslateArgs. See Driver.cpp BuildJobsForAction FIXME.
- [x] In Darwin’s addClangTargetOptions, skip host-stdlib flags when
DeviceOffloadKind != OFK_None so HIPSPV can safely delegate to the host.

first.
Refactored call sites:
- `Loop::setLoopAlreadyUnrolled` (LoopInfo.cpp)
- `Loop::setLoopMustProgress` (LoopInfo.cpp)

[Clang] Simplify target specific implementations in gpuintrin.h (#194669)
Summary:
Previously we had a three-way dance where the top-level defined an impl
then the lower level defined potentially an override and then we
stitched those together.
This simplifies that, instead just defining a macro that says whether
or not we need it. This works because the target-specific portions are
always included first, so this basically says "Do we need to make a
default version".

[AArch64] Optimize lowering of i1 vector reduction (#187912)
This pr optimizes code generation in AArch64 for comparing bitcast <N x
i1> results with 0 or -1 using eq/ne. For scenarios where only "all
zeros or all 1s" are considered, the backend no longer prioritizes
materializing packed bitmasks and using vector reduction methods like
addv/umaxv/uminv. Instead, it expands the boolean vector into a regular
integer vector and performs the comparison via a more direct scalar
comparison path. For 64-bit and 128-bit cases that can be folded down to
64-bit, a lighter instruction sequence like fmov + cmp/cmn + cset/csel
is generated.
Functionally, this brings several benefits:
- Optimized the `setcc(bitcast(vNi1), 0/-1)` and
`select_cc(bitcast(vNi1), 0/-1, ...)` modes.
- In scenarios like <8 x i1>, a zero/all-one check can be performed
directly on the entire comparison result, avoiding additional vector
lateral reduction.
- In 128-bit scenarios like <16 x i1>, the vector is first folded using
ext + orr/and before a scalar comparison is performed.

[WebAssembly] Fix EHPadStack calculation in fixCallUnwindMismatches (#194184)
After #187484, `fixCallUnwindMismatches` now runs after
`fixCatchUnwindMismatches`. But `fixCallUnwindMismatches` was not
handling newly generated `try_table`s and trampoline BBs in
`fixCatchUnwindMismatches` correctly. See the comments for details.
This is mean to replace #192968 and adds its test case to
`cfg-stackify-eh.ll` and `cfg-stackify-eh-legacy.ll`. (The bug only
happens in the standard (exnref) EH so `cfg-stackify-eh.ll`, but I added
the same test to `cfg-stackify-eh-legacy.ll` as well for more coverage.)
`exception.ll`'s `inlined_cleanupret`'s results have changed because we
were generating unnecessary `try_table`s, thinking there were call
unwind mismatches when there weren't. (This wouldn't have resulted in
incorrect execution; it just added more unnecessary instructions.) This
also fixes some comments for `inlined_cleanupret`, because "throw_ref
targets the top level cleanuppad" is confusing. (This comment was
probably copy-pasted from "delegate targets ...".)
Closes #192968.

This wraps the initialization in a cir.if conditioned on the allocation

This simplifies the check performed in a helper for diagnosing a cast

This fixes a regression introduced in
https://github.com/llvm/llvm-project/pull/132401, which landed in the
last release, and this will be back ported, so no release notes.

[clang] Fix interaction of __ob_wrap with signed divide. (#194474)
At first glance, signed divide overflow seems similar to other forms of
signed overflow, but it's significantly different: it's the only form of
signed overflow that is not affected by -fwrapv, it has undefined
behavior at the LLVM IR level, and it can trigger trap on x86.
Given that, make ubsan trigger on signed divide overflow even if a type
is marked __ob_wrap.

Fix #193892.
This is found during libc++ bringing up process. This patch:
- implement recursive mutex support for real.
- fix the issue that pthread mutex initializer and public mutex
interface misalign with internal representation. this was the root cause
that hangs the libc++ test as padding bytes effectively pollute the
futex state if default initializer was used.
- additionally, we changed the field to bitfield to allow encoding more
data. (e.g. the error checking flag that is not yet added). timed bit is
removed as we always support it anyway. PI bit is added instead.

[OpenMP] Fix use of uninitialized Dl_info when dladdr fails in ompd_init (#193643)
When dladdr() fails, dl_info is left uninitialized. The code printed the
error but then fell through to unconditionally call
strrchr(dl_info.dli_fname, '/'), accessing an uninitialized pointer --
typically NULL on the stack -- causing a SIGSEGV.
Fix by turning the second 'if' into 'else if', so the path-extraction
block is only reached when dladdr() succeeded and dl_info is valid.

[LLDB] Add module hook implementation (#185465)
Introduce a unified target hook command system for LLDB that handles
multiple target lifecycle events (module load, module unload, process
stop) through a single Hook class.
The existing target stop-hook commands remain unchanged for now, meaning
stop-hooks can now be created through either target stop-hook add or
target hook add -S.
A future follow-up can alias target stop-hook to the unified system to
consolidate the two paths.
New commands:
- target hook add [-o cmd] [-P class] [-u] [-S] - create a hook (fires
on module load by default, optionally on unload/stop)
- target hook add-filter [filter-opts] <hook-id> - attach stop-event
filters (shlib, function, file/line, thread) to an existing hook
- target hook list / delete / enable / disable - manage hooks
- target hook {enable,disable} {module-loaded|module-unloaded|stop-hook}
<id> - per-event toggling
top-event filter options live on a separate add-filter command rather
than on target hook add, keeping the add command clean and making the
system safe for filters on other event types.
Ran the tests + Made sure stop tests are passing as well.

CWG2810 (https://cplusplus.github.io/CWG/issues/2810.html) just removes
some wording that could be misinterpreted as saying "a compiler must not
emit any warnings in uninstantiated templates". Clang has never
misinterpreted it that way, so we don't need to do anything here.

[HLSL] Make load methods take const attribute (#193858)
Previously, HLSL shaders that declare a local resource const, cannot use
the `Load` method, since it is not attributed with const.
Load does not change a resource, it is a read-only operation, so the
method should be marked const.
This PR changes the methods so that they are marked const.

[AMDGPU][MIRFormatter] Printer & parser for S_WAITCNT human-readable mask (#193895)
This patch implements a printer and parser for the S_WAITCNT mask. It
prints the mask in a human-readable format, showing the counter values
like `Vmcnt_<NUM>_Expcnt_<NUM>_Lgkmcnt_<NUM>`.
The format matches the printing style of S_WAITCNT_DEPCTR. For example:
```
S_WAITCNT .Vmcnt_0_Expcnt_0_Lgkmcnt_0
S_WAITCNT .Expcnt_0
S_WAITCNT .AllOff
```
Counters at their maximum value (meaning "don't wait") are omitted. When
all counters are at max, `.AllOff` is printed.

[lldb] Define breakpoint location "." to mean the location(s) at which the current thread is stopped (#194272)
Adds `.` as a new `breakpt-id` syntax. Users can specify `.` to mean the breakpoint
location(s) that caused the current thread to stop.
I selected `.` to mean the current breakpoint locations for two reasons. In a shells,
period means <ins>current</ins> directory. In prose, a period is a <ins>stop</ins>.
My workflow often starts with multiple breakpoint locations, such as with regex
breakpoints, or basename breakpoints for overloaded/overridden names. As locations are
hit, I realize which locations are no longer needed. This new syntax makes it quick and
easy to disable the currently stopped location(s).
Another use case for this is to quickly repeat commands for the current location:
``` break com add -o 'p someVar' . ```
Usage example:
``` (lldb) b main.c:2 Process 47071 stopped * thread #1, queue =
'com.apple.main-thread', stop reason = breakpoint 1.1
frame #0: ... main`main at main.c:2:3
1 int main() {
-> 2 return 0;
3 }
Target 0: (main) stopped. (lldb) breakpoint disable . 1 breakpoints disabled. (lldb)
breakpoint list Current breakpoints: 1: file = 'main.c', line = 2, exact_match = 0,
locations = 1
1.1: where = main`main + 12 at main.c:2:3, address = ..., hit count = 1 Options:
disabled
```

Currently, if a MBB does not have a corresponding original bitcode BB,
because it was generated later in the backend,
`MachineBasicBlock::getName()` returns an empty string. This adds
`getBBName` method, which prints BB names in the format of
`bb.3.catch.start` in case the original BB name is `catch.start`, and
just `bb.3` when there is no matching original BB, and uses it for
`LLVM_DEBUG` statements.

[git] [LLVM utils] Require `pyjwt[crypto]==2.12.1`, `cryptography==47.0.0`, and `urllib3==2.6.3` (#194707)
**Context:**
The MSVC team (👋 ) consumes the LLVM repo and is receiving security
alerts due to the git utils `requirements.txt` file requesting
transitive dependencies with known CVEs.
Namely, we're looking at the following CVEs:
- https://nvd.nist.gov/vuln/detail/CVE-2026-32597, fixed in
`pyjwt>=2.12.0`
- https://nvd.nist.gov/vuln/detail/CVE-2026-26007, fixed in
`cryptography>=46.0.5`
- https://nvd.nist.gov/vuln/detail/CVE-2026-21441, fixed in
`urllib3>=2.6.3`
**This PR** aims to address this re-computing the `requirements.txt` for
those dependencies, via:
> pip-compile --generate-hashes --upgrade-package pyjwt
--upgrade-package cryptography --upgrade-package urllib3
--output-file=requirements.txt requirements.txt.in

[CIR] __builtin_source_location lowering for constant (#194505)
This handles the UnnamedGlobalConstantDecl lowering, which is only used
for the source-location object. This uses similar logic to the classic
compiler, so we end up with roughly the same IR.
There is a slight difference in how we choose which strings to uniquify
(preexisting) and how we name them/name duplicates, but it isn't really
relevant to the text itself.

[WebAssembly][GlobalISel] Migrate to extended LLT (#193047)
Moves Wasm GISel to use the the new extended LLTs added by #155107.
Extended LLTs have (optional) information about whether a particular
scalar is integer vs floating-point. This is a big win for Wasm, since
we can avoid a lot of guess work, and map LLT i32, i64, f32, and f64
directly to their Wasm counterparts.
To take full advantage of this, RegBankSelect has been automated,
iterating over all operands and mapping typed LLTs to their appropriate
register bank.

[CIR] Always set base subobject type for C++ records (#194504)
For unions and final C++ classes, computeRecordLayout previously left
the base-subobject type as a default-constructed (null) cir::RecordType.
The non-virtual size always equals the size for those kinds of records,
so no separate ".base" variant is needed, but `BaseSubobjectType` itself
was never set to the complete type either.
That null leaked through
getCIRGenRecordLayout(RD).getBaseSubobjectCIRType(), which is called by
getStorageType(const CXXRecordDecl *) when laying out a
[[no_unique_address]] / potentially-overlapping field. The null
mlir::Type was then stored as MemberInfo::data and tripped a
SmallVector::back() !empty() assertion in
CIRRecordLowering::fillOutputFields, because a member with null data is
interpreted as a bitfield placeholder and reads fieldTypes.back() that
was never pushed.
Match classic CodeGen (CGRecordLayoutBuilder.cpp) and unconditionally
set baseTy = *ty for any CXXRecordDecl, only constructing a separate
".base" record when nv-size != size (which excludes unions and final
classes by construction).
Reproducer:
```
union U { int a; long b; };
struct S {
[[no_unique_address]] U u;
int x;
} s;
```
This comes from a crash on the libc++ test-suite (~1,500 tests affected,
all crashing inside CIRRecordLowering::lower while laying out
__compressed_pair_padding-style structs in <string>).

[flang] Do not mark CUDA device variables as dso_local (#194500)
A follow-up to https://github.com/llvm/llvm-project/pull/189709.
```fortran
integer, constant :: zzz = 4
bind(c, name='zzz_from_c') :: zzz
```
In this code, `zzz` is a CUDA `constant` variable with an initializer.
With PIE enabled, flang marks it as `dso_local`, causing LLVM to emit
direct addressing (`leaq`) instead of GOT-indirect addressing (`movq
@GOTPCREL`). The CUDA runtime interposes on these symbols via
`cudaRegisterVar`, so the wrong address gets registered, leading to a
segfault.
Fix: skip `dso_local` for globals with a CUDA data attribute.

[RISC-V][RVY] Add a DataLayout component for CHERI capabilities
This adds a new pointer address space to the data layout when RVY is
enabled, making use of the new 'e' flag for pointers with
[external state](https://github.com/llvm/llvm-project/pull/105735).
I chose address space 200 since that is what has been used in the
downstream CHERI forks for the past decade and therefore makes it slightly
easier to upstream tests, etc. but am happy to use any other value if that
is preferred. We can look at the ABI name parameter to detect
pure-capability ABIs, so this does not support the "hybrid" CHERI case that
is supported downstream where capability registers are supported (i.e.
the AS200 pointer attributes exist in the data layout), but the default
address spaces are still integers instead of AS200.
to handle the "hybrid" case where only some pointers use Y registers.

[ORC] Move JITLinkMemoryManager ownership out of ExecutorProcessControl. (#192665)
Removes the JITLinkMemoryManager pointer and getMemMgr() accessor from
ExecutorProcessControl, replacing them with a
createDefaultMemoryManager() virtual factory method. This follows the
same decoupling pattern applied to DylibManager and MemoryAccess in
earlier patches.
JITLinkMemoryManager ownership moves to the client:
- LLJIT gains a MemMgr member and a MemoryManagerCreator builder hook.
- EPCIndirectionUtils takes a JITLinkMemoryManager& parameter.
- LinkGraphLinkingLayer and ObjectLinkingLayer lose their no-arg
constructors (MemMgr is now required).
- SimpleRemoteEPC::Setup is removed; custom memory manager selection now
happens at the client level rather than during EPC setup.

The original change was reverted in the following commits:
1) ec9d7d18bdfe21c30c94c02f14f3613f7b69a17b (#194087)
2) c26ae41c8765fdd073c71061f21a83a161598901 (#194695)
This reland incorporates the following fixes:
1) Change LLVM_ENABLE_OPENCSD to default to OFF (opt-in).
2) Parse the OpenCSD version from ocsd_if_version.h and gate OpenCSD
support on a minimum version of 1.5.4 to avoid compilation errors.
3) Refactor the test feature detection to use a
configure-time LLVM_HAVE_OPENCSD variable instead of runtime checks in
lit.local.cfg.

[CodeGen] Use SmallMapVector for SpillPlacement::Node::Links (#194653)
Previously, `SpillPlacement::Node::Links` was implemented as a
`SmallVector` of `(Weight, BundleNo)` pairs.
This patch replaces the `SmallVector` with a `SmallMapVector<unsigned,
BlockFrequency, 4>`, which stores `(BundleNo, Weight)` pairs. This
allows for more efficient lookups and weight accumulations when multiple
links to the same bundle are added.

[mlir][xevm] Fix greedy rewriter crash in HandleVectorExtractPattern matches shuffles on block arguments (#192213)
`HandleVectorExtractPattern` could report `success()` without rewriting
the IR when `llvm.shufflevector` extracted a contiguous slice from a
**block argument** (no defining op). The greedy rewriter’s expensive
checks then aborted with *“pattern returned success but IR did not
change”*.
The pattern only performs work when the shuffle’s operand is defined by
another op (`FPExt`, `FPTrunc`, `bitcast`, nested `shufflevector`, or
`load`). For operands like function arguments, `getDefiningOp()` is
null, so nothing is rewritten; the function still fell through to
`return success()` without changing the IR and would crash when
`MLIR_ENABLE_EXPENSIVE_PATTERN_API_CHECKS` is on. `mlir-opt
--convert-xevm-to-llvm --split-input-file
mlir/test/Conversion/XeVMToLLVM/xevm_mx-to-llvm.mlir` no longer hits the
fatal error.

[AMDGPU][MC] update USER_SGPR_COUNT bits for GFX1250 (#192579)
When we work on the triton kernel with tensor descriptor created on the
host side, there is a error message `amdgpu_user_sgpr_count smaller than
than implied by enabled user SGPRs`.
After some debugging, we find the `USER_SGPR_COUNT` is not updated with
GFX125 and this patch updates it for USER_SGPR_COUNT from
https://llvm.org/docs/AMDGPUUsage.html#amdgpu-amdhsa-compute-pgm-rsrc2-gfx6-gfx12-table.
On GFX125, COMPUTE_PGM_RSRC2::USER_SGPR_COUNT is 6 bits wide. The MC
helper S_00B84C_USER_SGPR only masks to 5 bits; when the true user SGPR
count is 32 or more, the masked value wraps (e.g. 32 -> 0).
`AMDGPUAsmPrinter` then emits a .amdhsa_user_sgpr_count with 0, that
disagrees with the implied count from enabled user SGPRs (including
kernarg preload), and finally assembling llc output with `llvm-mc` fails
in `AMDGPUAsmParser`

[clangd] Resolve __builtin_offsetof designator components precisely (#194407)
Building on the new TraverseOffsetOfNode hook in RecursiveASTVisitor and
the OffsetOfNode DynTypedNode kind, teach SelectionTree, FindTarget, and
the explicit-references collector to address each designator component
individually. Cursor positions inside a nested designator (for example
the 'B' in __builtin_offsetof(A, B.c)) now resolve to the corresponding
field instead of always picking the innermost component.
- SelectionTree: wrap each OffsetOfNode visit in traverseNode so it
becomes a selectable node alongside its enclosing OffsetOfExpr.
- FindTarget::allTargetDecls: resolve OffsetOfNode (Field kind) to its
FieldDecl, and drop the OffsetOfExpr fallback so non-component
selections do not guess a field target.
- ExplicitReferenceCollector: emit one ReferenceLoc per component via a
new VisitOffsetOfNode hook, replacing the manual component loop in
refInStmt.
Tests:
- TargetDeclTest.OffsetOf: precise resolution for outer/inner/base/
identifier components, macro form, array index expressions, and
non-component selections.
- Hover.All and Hover.OffsetOfBuiltin: field cases for nested offsetof,
and expression hover on the builtin token.
- LocateSymbol.All: simple, outer, inner, macro, inherited-field, and
builtin-token cases.
- AllRefsInFoo: existing offsetof cases continue to pass via the new
per-component VisitOffsetOfNode path.

[flang] Avoid exponential traversal in deep type extensions (#191955)
`HasDestruction()` and `IsFinalizable()` walked component iterators that
already descend into parent scopes, and then also recursed through
derived-type components. With deep type extension chains, that caused
the same inheritance structure to be traversed repeatedly and compile
time to grow exponentially.
Iterate only over the current type scope instead. The scope contains the
type's own components plus its parent component, so the existing
recursion through derived-type components still handles inheritance
without double traversal.
Add a regression test with a deep type extension hierarchy.

[ThinLTO] Preserve Unicode characters in module paths when writing the combined-index (#194320)
`IndexBitcodeWriter::writeModStrings()` serializes module path strings
into a `SmallVector<unsigned>` before emitting `MST_CODE_ENTRY` records.
When a path contains UTF-8 bytes with the high bit set, appending from
`StringRef::begin()/end()` can be incorrect. Instead, append the module
path through `bytes_begin()/bytes_end()`, so the bitcode writer always
serializes unsigned bytes.

[DA] Disable the BanerjeeMIV dependence test (#174733)
The various `findBounds` helpers (e.g. `findBoundsLT`) are suspected to
be incorrect because they do not account for potential integer overflow,
which can lead the dependence analysis to produce incorrect results.
Since these helpers are used by the BanerjeeMIV dependence test, this
patch disables BanerjeeMIV by default to avoid unsafe results and
progress the default enablement of DA. The Banerjee test is required for
our motivating example, and we will working on correctness issues and
reenabling it after default enablement.
This is working around issue: #169813

[flang][pft] visit original symbol in acc use_device (#194588)
Fix regression after https://github.com/llvm/llvm-project/pull/193689
when a use_device is referring to variables from a host module.
The original symbol needs to be visited in the PFT so that it will be
instantiated, but it is not visible anymore from the parse tree, and not
directly connected to the new symbol (this is because variables in
use_device are treated in a special way in order to give them the DEVICE
attribute, other data clause do not need such handling).
Look into the parent scope for a symbol with the same name and visit it.

[X86] Attempt to fold extract_vector_elt(logicop(x,y),i) -> extract_vector_elt(x,i) (#194581)
When extracting from logicops, we often don't need to extract the result
if one of the element sources is identity (and(x,-1) -> x, or/xor(x,0)
-> x etc.), so this patch uses SimplifyMultipleUseDemandedVectorElts to
peek through to an underlying build_vector.
I had hoped to make this generic, but there's still a lot of yak shaving
to deal with first, as usual - I've included the minimal x86-specific
fixes:
* missing constant folding of (vXi1 logicop(bitcast(c1),bitcast(c2)))
* fold kshiftr(concat_vectors(x,y,z,w),c) -> concat_vectors(z,w,0,0)

[SPIRV] Add missing OpenCL atomic_fetch_min/max builtin mappings (#190443)
## Summary
The SPIR-V backend maps OpenCL `atomic_fetch_add`/`sub`/`or`/`xor`/`and`
(and their `_explicit` variants) to SPIR-V atomic opcodes, but was
missing support for `atomic_fetch_min`/`atomic_fetch_max`, their
`_explicit` variants, and the legacy `atom_min`/`atom_max` builtins.
This caused OpenCL programs using these atomics to emit unresolved
function calls instead of the correct
`OpAtomicSMin`/`OpAtomicSMax`/`OpAtomicUMin`/`OpAtomicUMax`
instructions.
### Approach
Unlike add/sub/or/xor/and (which are sign-agnostic), min/max require
distinct signed vs unsigned SPIR-V opcodes. Rather than inspecting the
`OpTypeInt` signedness bit at runtime (which is always 0 in this
backend), this patch uses the existing prefix-based builtin lookup
mechanism in `lookupBuiltin`: the itanium demangler exposes the argument
type (`int` vs `unsigned int`), and the lookup adds an `s_` or `u_`
prefix accordingly, matching the correct `.td` entry.
### Changes
- **`SPIRVBuiltins.td`**: Add 12 prefixed `DemangledNativeBuiltin`
entries (`s_`/`u_` variants for `atomic_fetch_min`, `atomic_fetch_max`,
`atomic_fetch_min_explicit`, `atomic_fetch_max_explicit`, `atom_min`,
`atom_max`)
- **`SPIRVBuiltins.cpp`**: Add
`OpAtomicSMin`/`OpAtomicSMax`/`OpAtomicUMin`/`OpAtomicUMax` cases to the
`generateAtomicInst` switch to route these opcodes to
`buildAtomicRMWInst` (also fixes the pre-existing
`__spirv_Atomic{S,U}{Min,Max}` builtins that were defined in `.td` but
not handled in the switch)
- **New test**: `atomic_fetch_min_max.ll` covering all 6 builtins for
both signed and unsigned `i32` types

[MLIR][GPU] Add cooperative launch support to gpu.launch_func (#190639)
Add a `cooperative` UnitAttr to `gpu.launch_func` that enables
cooperative kernel launch semantics. Cooperative launches guarantee that
all thread blocks in the grid are co-resident on the GPU simultaneously,
enabling grid-wide synchronization patterns.
## Implementation
When `cooperative` is set (with or without cluster sizes), the lowering
emits a call to the new `mgpuLaunchKernelCooperative` runtime function,
which uses `cuLaunchKernelEx` with a `CUlaunchConfig` and
`CU_LAUNCH_ATTRIBUTE_COOPERATIVE`. This API is guarded behind
`CUDA_VERSION >= 12000`. The HIP path funnels through
`hipModuleLaunchCooperativeKernel`.
## Changes
- **GPUOps.td**: add `cooperative` UnitAttr and assembly format keyword
- **SelectObjectAttr.cpp**: add `getKernelLaunchExFn()`, route
cooperative and/or cluster launches through `mgpuLaunchKernelEx`
- **CudaRuntimeWrappers.cpp**: implement `mgpuLaunchKernelCooperative`
via `cuLaunchKernelEx` or `hipModuleLaunchCooperativeKernel`, depending
on platform
- **GPUToLLVMConversion.cpp**: propagate cooperative attribute through
the legalization pattern
- **test/Dialect/GPU/ops.mlir**: round-trip tests for cooperative
keyword with and without clusters
## Context
MLIR currently has no support for cooperative kernel launches. Flang
works around this with a CUF-specific attribute (PRs #124325, #124362),
but there is no first-class support in the GPU dialect. This patch adds
it at the `gpu.launch_func` level so all frontends can use it.

It looks like handling this in createPartialReductionExpression would

[llvm-ir2vec] Place IR2Vec Python bindings in the tools/llvm-ir2vec/Bindings build directory (#194301)
## Place IR2Vec Python bindings `.so` in the Bindings build directory
Without an explicit output directory, CMake places the nanobind
extension module
in `<build>/lib/`, alongside unrelated LLVM libraries.
- This change adds `set_target_properties` to redirect the output to
`<build>/tools/llvm-ir2vec/Bindings/`, keeping the Python bindings
isolated within its own tool's build tree. This mirrors MLIR's
convention,
where Python extension modules are placed under
`<build>/tools/mlir/python_packages/` rather than the global `lib/`
directory.
- %llvm_lib_dir was pointing to build-llvm/lib but the .so actually
lives at build-llvm/tools/llvm-ir2vec/Bindings/. The tests were silently
passing only because the conda env's site-packages had ir2vec installed,
masking the broken PYTHONPATH entirely.
- Two changes:
- `lit.local.cfg` — replaced `%llvm_lib_dir` substitution with
`%ir2vec_python_dir` pointing to the correct build output path
- All 6 test `.py` files — updated the RUN line from
`PYTHONPATH=%llvm_lib_dir` to `PYTHONPATH=%ir2vec_python_dir`

[OMPT][OpenMP] Use omp_initial_device for host in callbacks (#192924)
The OpenMP specification offers different ways for identifying the host
device. While users of the OpenMP API can use `omp_get_initial_device()`
or the constant `omp_initial_device` (available since OpenMP v5.2), a
tool needs to rely on the `initial_device_num` passed by the OpenMP
runtime during the `initialize` callback.
In #134451, it was discovered that the `initial_device_num` passed is
always `0`, regardless of any device are available for offload
execution. For host-only OpenMP code, this matches the result of
`omp_get_num_devices()`, and is a valid result. In the case of devices
being available though, this passed identifier is incorrect. While
`libomp` calls `omp_get_num_devices()`, `libomptarget` has not fully
initialized its PluginManager at that point, hence returning no
available devices. Tools relying on `initial_device_num` might therefore
incorrectly assume host-side execution when some code runs on a device.
Since the `ompt_get_num_devices()` entry point is also not fully
implemented, tools currently need to do on-the-fly handling for the host
device.
To make handling easier, consistently use the `omp_initial_device`
identifier as the `initial_device_num` and for all device callbacks.
This does not rely on knowing the number of available devices during
OMPT initialization in the runtime and ensures a consistent value for
tools to handle.
Closes #134451

[libc++] Disable mistakenly enabled `optional<T&>` constructors for `optional<T>` (#194446)
Resolves #194415
- A constructor specifically meant for `optional<T&>` was left enabled
for `optional<T>`
- Fix it, and add a test to check for regression.
- This patch also corrects the constraints for `optional(optional<U>&)`
and `optional(const optional<U>&)` , as they were incorrectly
disallowing [valid conversions](https://godbolt.org/z/1r5Ea7z5M)
- Also, correct the `noexcept` specification.
- Add tests for both corrections.

[LLD][ELF] Fix performance regression when using linker scripts (#194668)
The addition of the support for `--enable-non-contiguous-regions` from
PR #90007 moved an "early out" condition in
`LinkerScript::computeInputSections()`. This could result in other
relatively expensive checks, i.e. `pat.sectionPat.match`,
`cmd->matchesFile`, `pat.excludesFile` and `flagsMatch`, to be performed
unnecessarily in the default situation where
`--enable-non-contiguous-regions` is disabled.
This fix restores the "early out" condition and shows an ~14%
improvement for the Linux kernel benchmark link and has been seen to
improve performance by up to ~30% for a large UE5 link.

[LLD][COFF] Use lazy object mechanism instead of relying on the archive map for thin archives on ARM64EC (#194349)
On ARM64EC/ARM64X, an archive may contain both native and EC symbols in
the symbol table, which can potentially conflict. Regular archives
handle this using the extended archive format, which stores the EC
symbol table in a separate section, but this is not available for thin
archives.
Work around this limitation by lazily parsing all thin archive members
instead of relying on the archive symbol table. This uses the same
mechanism as when thin archive members are passed with
-start-lib/-end-lib, where symbols are added to the symbol table without
pulling in the object file unless it is referenced.
Fixing this at the archive format level would require changes to the
format. Currently, the ECSYMBOLS section is supported only by the COFF
archive format, while thin archives require the GNU format. We would
either need to extend the COFF format to support thin archives or
introduce ECSYMBOLS support in the GNU format.

[mlir][Presburger] Fix inlining failure for dynamicAPIntFromInt64 in debug builds (#194820)
When `dynamicAPIntFromInt64` is passed as a function pointer to
`llvm::transform`, it becomes an indirect call. This causes the compiler
to fail to inline the function despite the
`LLVM_ATTRIBUTE_ALWAYS_INLINE` annotation, resulting in a compilation
error in debug builds:
```
error: inlining failed in call to 'always_inline' 'llvm::DynamicAPInt llvm::dynamicAPIntFromInt64(int64_t)': indirect function call with a yet undetermined callee
250 | LLVM_ATTRIBUTE_ALWAYS_INLINE DynamicAPInt dynamicAPIntFromInt64(int64_t X) {
```
Fix this by wrapping `dynamicAPIntFromInt64` in a lambda, turning the
indirect call into a direct call that the compiler can inline at the
call site.

[clang][Lex] Collapse relative extern module paths when recursing to prevent unbounded path length growth. (#193691)
Ref #147220.
### Problem Description
Bazel's use of clang modules for its `layering_check` emits `extern
module` declarations relative to some base path meaning those paths
usually include long sequences of `../` followed by the path to the
module itself.
When parsing `extern module` in the module file, we (I believe
intentionally) silently ignore missing module files. Currently in the
problem case if the file existence check failed for any _other_ reason
it also silently ignores it. This means that `-fmodules-strict-decluse`
that bazel uses for the layering_check can throw a spurious
`err_undeclared_use_of_module` error which is the problem reported in
#147220.
Clang's `extern module` parsing chooses to concatenate these relative
paths recursively meaning the growth in those paths is unbounded. In
this case the file existence check fails due to the path name being too
long (ENAMETOOLONG in POSIX).
In summary there are possibly 2 underlying problems that contribute to
#147220 that we could try to fix:
1. Silently ignoring unexpected errors (ENAMETOOLONG) meaning the
ultimately reported error (undeclared use of module) doesn't really help
the user understand what was wrong.
2. Unbounded path growth when recursively declaring `extern module`s in
a chain.
I'm choosing to focus on (2) in this PR because both fixes seem useful,
and (1) seems an intentional design choice.
### Implementation
Collapse `../` in relative `extern module` paths before loading those
modules for parsing.

[InstSimplify] Fix invalid dereference in simplifyBinaryIntrinsic (#194825)
For the simplifyBinaryIntrinsic interface the `Call` argument passed in
may be null, which differs from other interfaces such as
simplifyIntrinsic and simplifyUnaryIntrinsic which require `Call` to be
non-null. See FoldBinaryIntrinsic in InstSimplifyFolder.h where the
`Call` argument has a default value of null.
That means for all uses of `Call` in simplifyBinaryIntrinsic we must
first check the pointer is not null to avoid an invalid dereference.
This PR fixes the case for the get.active.lane.mask intrinsic.
There isn't currently an easy way to test this fix because the only
place I can see where FoldBinaryIntrinsic is called without a null
`Call` is VPlanTransforms.cpp and we don't currently invoke the function
for get.active.lane.mask intrinsics.

[llvm][YAML] Support aliases (anchors) in YAMLIO (#146371)
This change makes it possible to use YAML anchors [1], [2] with
YAMLTraits. All of the necessary parser machinery already exists, so the
only change that is necessary is to wire it up to YAMLTraits.
This is done by keeping track of all `Anchor` -> `HNode *` mappings and
reusing those when an `AliasNode` is encountered.
In accordance with the spec [2], anchors do not have to be unique and
refer to the last occurrence in the serialization.
Example usage:
```yaml
foo: &a 42
bar: *a
```
The above would be deserialized as:
```yaml
foo: 42
bar: 42
```
Note that aliases are a serialization detail and can be discarded during
composition into a Representation Graph (`HNode` hierarchy).

[LLVM] Provide a default 'multilibs.yaml' when configured (#192281)
Summary:
Right now it's a little difficult to use the multilibs support because
the user must manually provide one. I believe that when the user
configures multilibs with the LLVM CMake arguments at a minimum we
should provide one that forward `-fmultilib-flag=<multilib>` to the
created runtime.
This RP makes CMake emit this by manually writing a flag. Because users
could provide their own, this adds some extre complexity to prevent this
from being overwritten.
The desire for this change is to more easily ship this support in CMake
configuration files without needing to write files manually (for the
typical case).

__ret = __builtin_shufflevector(__rev0, __rev1, 0, 8, 1, 9, 2, 10, 3, 11);
__ret = __builtin_shufflevector(__ret, __ret, __lane_reverse_64_8);
return __ret;
}
#endif
```
So no additional special lowering logic is needed.

Fixes https://github.com/llvm/llvm-project/issues/194596.
When the function result symbol is encountered while the compiler is
already completing the function result type, flang could recursively
re-enter _CompleteFunctionResultType()_ and crash on invalid code.
Instead of crashing on conflicting declarations, flang now reports an
“already declared” error and stops further recursion.

Handle AVX-512 VGF2P8AFFINEQB rmbi instructions in X86MCInstLower.
Unlike the existing rmi forms, rmbi uses a 64-bit broadcast memory
operand, so the constant pool entry may only contain the broadcast
source instead of a full-width vector constant. Print that constant
repeated across the destination vector width when forming the asm
comment.

[CodeGen] Use getFnAttributeAsParsedInteger for patchable-function attributes (#194726)
Replace `getAsInteger()` parsing of the `patchable-function-entry`
and `patchable-function-prefix` function attributes with the existing
`Function::getFnAttributeAsParsedInteger()` helper across AsmPrinter
and all backend targets.
The IR verifier already validates these attributes as unsigned base-10
integers via `checkUnsignedBaseTenFuncAttr`, so parse failure at point
of use indicates a verifier bypass or IR corruption.
`getFnAttributeAsParsedInteger()` returns a default of 0 on failure
(matching the implicit behavior of the old code) and emits a diagnostic
rather than silently continuing.

[TableGen] Use guarded assert in constexpr functions (#194728)
The constexpr functions in question take a scoped enum as an argument
and a switch statement returns a value for each value of the enum. These
are all legal statements in a constexpr function in C++14.
Under constexpr rules, the evaluation of a constexpr function cannot
lead to an evaluation of any prohibited forms of expressions. An
evaluation of the functions being discussed with a valid argument will
terminate at the switch, and an code that follows will not be evaluated.
Using "llvm_unreachable" after the switch should be ok as long as the
expansion of the llvm_unreachable macro does not contain any statements
not allowed to appear in a constexpr function. At the same time, GCC
before v9 did not tolerate any unguarded calls to non-constexpr
functions after the switch.
To avoid using "llvm_unreachable", which can have multiple expansions,
use an assert with an explicit condition that the underlying value of
the argument lies between the minimum and maximum values of the enum.

combineMinMaxReduction will go away once we can use
shouldExpandReduction, rely on the middle-end to recognise reductions
and not have to recreate them from the expanded patterns.
I've added pre-SSE41 handling using vector unrolling - hopefully this
will go away once #194672 is in place.

[CIR][AArch64] Lower NEON vzip intrinsics (#193658)
### Summary
part of https://github.com/llvm/llvm-project/issues/185382
lower part of intrinsics in :
https://arm-software.github.io/acle/neon_intrinsics/advsimd.html#zip-elements
Lower NEON::BI__builtin_neon_vzip_v and NEON::BI__builtin_neon_vzipq_v
in CIRGenBuiltinAArch64.cpp by porting the existing incubator logic
(`clangir/clang/lib/CIR/CodeGen/CIRGenBuiltinAArch64.cpp`) onto ClangIR:
two bitcasts on the input vectors, two rounds of cir.vec.shuffle
generating the low/high interleave patterns, each stored through a
ptr_stride of the sret base pointer.
### Test
- test_vzip_mf8
- test_vzipq_mf8
I found that these two intrinsics are defined in
`llvm-project/clang/test/CodeGen/AArch64/fp8-intrinsics/acle_neon_fp8_untyped.c`,
but this file seems to be a test suite specifically for the `mfloat8`
type, so I did not remove their original test cases.
Some of the new CHECK lines additionally match a pair of bitcasts before
the shuffle; this shape comes from arm_neon.h's inline wrappers, which
re-cast typed vectors (e.g. <4 x i16>) through <8 x i8> before calling
__builtin_neon_vzip_v. Variants whose element type is already i8
(s8/u8/p8/mf8) skip that round-trip and therefore have no bitcasts in
the check lines.

[RISCV] Use BufferSize = 0 for ProcResGroup in SiFive7 scheduling models (#194754)
As it turns out, even if a `ProcResGroup` consists of in-order pipes, as
long as its (the group's) BufferSize is not zero, Machine Scheduler will
not use in-order scheduling on instructions that consume it. Since
BufferSize also defaults to -1 for `ProcResGroup`, we have been
scheduling the resource consumption of SiFive7's `PipeAB` (scalar pipes)
and `VA1OrVA2` (vector pipes) in an out-of-order fashion!

[LoopVectorize] Add metadata to distinguish vectorized loop body from scalar remainder (#190258)
Add two new loop metadata attributes — `llvm.loop.vectorize.body` and
`llvm.loop.vectorize.epilogue` — that the loop vectorizer sets on the
generated vector loop and epilogue loop respectively. The metadata is
only emitted when optimization remarks are enabled (`ORE->enabled()`),
so it has zero cost in normal compilation.
These enable downstream passes (LoopUnroll, WarnMissedTransforms) to
produce more precise optimization remarks. Instead of the generic "loop
not unrolled" warning on a source line that was vectorized, the unroller
can now report:
- **"vectorized loop"** for the main vector body
- **"epilogue loop"** for the scalar epilogue/remainder
- **"epilogue vectorized loop"** for an epilogue that was itself
vectorized during epilogue vectorization (carries both attributes)
A shared `getLoopVectorizeKindPrefix()` helper in
`LoopUtils.h`/`LoopUtils.cpp` reads the metadata and returns the
appropriate prefix string, used by both `LoopUnroll.cpp` and
`WarnMissedTransforms.cpp`. The metadata emission in `VPlan.cpp` uses
`Loop::addIntLoopAttribute` from the NFC PR #194676.
Two end-to-end tests exercise the full `loop-vectorize → loop-unroll`
pipeline with forced epilogue vectorization
(`-enable-epilogue-vectorization -epilogue-vectorization-force-VF=4`) to
produce all four loop categories from a single vectorizable function.
Each test also includes a plain (non-vectorized) function to cover the
baseline "loop" case. Both tests verify stderr diagnostic output and
YAML structured remarks.
**`LoopUnroll/vectorizer-loop-kind-remarks.ll`** checks for
successful-unroll remarks.
**`LoopTransformWarning/vectorizer-loop-kind-unroll-warning.ll`** checks
for failed-unroll warnings.

[RISCV] Fix crashes and add RV32 RUN line to rvp-simd-64.ll (#194782)
Prevent combinePExtTruncate from forming RISCVISD nodes with illegal
type. Remove unnecessary call to getSimpleVT().
Legalize shift amount when custom legalizing i64 shifts.
SelectionDAGBuilder usually pre-legalizes shift amounts. If we scalarize
a vXi64 vector shift the shift amount will be i64.

Introduce a dedicated cleanup flag for SEH __finally blocks and use it
to separate SEH try cleanup emission from C++ object cleanup emission
This prevents __finally cleanups from emitting seh.scope.begin/end and
keeps destructor/delete cleanups paired with seh.scope markers

[lldb] Decorate tests that use shared libraries (#193118)
`wasip1` does not support shared libraries in the traditional POSIX
sense. It was designed primarily as a monolithic system interface for
standalone modules where everything is statically linked. `wasip2`
introduced a "component model" where components achieve the goals of
shared libraries.

[lldb] Add skipIfWasm decorator and skip unsupported WebAssembly tests (#194761)
Add a new `skipIfWasm` test decorator that skips tests on the "wasip1"
and "wasi" platforms, and apply it to the test classes that rely on
expression evaluation or lldb-server, neither of which is available when
debugging WebAssembly targets.

[lldb] Handle ConstantExpr constants in InjectPointerSigningFixupCode (#194476)
Currently, the injection code assumes we encounter ConstantAggregate
constants and emits a GEP to access the fields/members. However, it's
possible for a CPA to be an operand of a ConstantExpr (e.g. a bitcast).
Emitting a GEP in that scenario doesn't make sense. This should instead
be handled by keeping track of the path to the CPA (which operands need
to be followed from the top-level ConstantExpr).
After this change, most arm64e tests that crash LLDB either pass or fail
with some other issue. The main exception is TestWeakSymbols.py which
needs more work.

[flang][HLFIR] Fix crash in WHERE with exactly_once inside elemental (#194443)
Fix a segfault in LowerHLFIROrderedAssignments when compiling a WHERE
statement whose mask contains an array constructor with an implied-do
loop (e.g. WHERE([(f(J), J=1,N)]) ...). The hlfir.exactly_once op inside
the hlfir.elemental has live-in values that are block arguments from the
enclosing elemental, which canonicalizeExactlyOnceInsideWhere cannot
pull into the exactly_once region.
The fix has two parts:
1. In canonicalizeExactlyOnceInsideWhere, skip exactly_once ops nested
inside hlfir.elemental and skip block argument live-ins, since these
cannot be relocated.
2. In both overloads of inlineElementalOp, handle hlfir.exactly_once by
inlining its body and cleanup operations instead of cloning the op
verbatim (which left an illegal op after lowering).

[Offload] Clean up and split Shared/Utils.h (#194876)
Summary:
This is used in the GPU portion of the build, but really shouldn't be.
Most of these helpers were only used by the GPU portion, which has much
nicer builtins available in new clang. Using these in the main offload
build is broken on Windows and not available on older compilers, so we
split. Also means one less header we share.
The alignment helpers are trivially replaced by an LLVM utility, the
only thing that remains are the pointer arithmetic functions. There's no
conveient place to put these so I just let them stay.

[WebAssembly] Remove exception deferring in CFGSort (NFC) (#194905)
This logic was added in
https://github.com/llvm/llvm-project/commit/ea8c6375e3330f181105106b3adb84ff9fa76a7c
(and extended to support multiple srcs in
https://github.com/llvm/llvm-project/commit/aa097ef8d474c925e4fbe0efcaad253266c2fd6f).
But as in the case of #191495, we don't need this logic anymore after
#130374. The reason is the same as #130374, but in this PR's context, in
the deleted comments,
> there can be cases in which, for example:
> EHPad A's unwind destination (where the exception lands when it is not
caught by EHPad A) is EHPad B, so EHPad B does not belong to the
exception dominated by EHPad A. But EHPad B is dominated by EHPad A, so
EHPad B can be sorted within EHPad A's exception.
This can't happen anymore, because if an invoke BB throws, and EHPad A
is the first unwind destination, and EHPad B is the next unwind
destination when EHPad A does not catch an exception, EHPad B should be
listed as a successor of the invoke BB; so it can't be 'dominated' by
the EHPad A, after #130374, from which we use the common
`findUnwindDestinations`.
This removes the unwind destination -> sources mapping in
`WasmEHFuncInfo`, because it was added to support this CFGSort logic.

[SandboxVec][SeedCollector] Change vector bit width calculation (#194090)
On GPUs `TTI::getRegisterBitWidth(TargetTransformInfo::RGK_FixedWidthVector()` returns the element bit width, not the whole vector size as it does on the CPU. So this patch changes this to a call to `getLoadStoreVecRegBitWidth()`, which depends on the address space, so it also moves the calculation per seed.
This patch also adds an AMDGPU lit test directory with a simple test.

[LifetimeSafety] Generalize invalidating member function detection (#194907)
This PR adds support for invalidating references after reassigning a
`unique_ptr` or calling its `reset` member function.
Previously, invalidation handling was limited to container-like types.
This PR generalizes the helper for detecting invalidating member calls
and adds `unique_ptr`'s `reset` member function as an invalidating one.
Since `unique_ptr` is now handled by this helper, reassignment through
`operator=` is also treated as invalidating.

[VPlan] Add transform to replace VPWidenCanonicalIV with wide IV. (#194267)
Add a new cost-based transform that replaces VPWidenCanonicalIVRecipe
with a canonical VPWidenIntOrFpInductionPHIRecipe, if it does not
increase spills.
The main benefit of VPWidenCanonicalIVRecipe is that it has shorter
live-ranges than wide IV phis. The new transform introduces wide IV
unless VPWidenCanonicalIVRecipe is cheaper or the wide IV introduces
additional spills.
This introduces wide IVs in a number of cases, where previously had
VPWidenCanonicalIVRecipe, because there was no existing wide canonical
IV we could re-use. It should also help avoid somewhat unrelated changes
in https://github.com/llvm/llvm-project/pull/190191.

Avoid indirect branches from cold sections when BTI is enabled (#194727)
Fixes #194489
Profile-guided optimizations such as AutoFDO can split functions into
hot and cold sections. During the branch relaxation pass, cross-section
branches that are out-of-range may be relaxed.
If X16 is in use at the branch site, the
AArch64InstrInfo::insertIndirectBranch pass may scavenge a free register
to perform the indirect branch. However, because the
AArch64BranchTargets pass runs before branch relaxation, the target
block in the hot section is not guaranteed to start with a BTI landing
pad instruction.
To avoid this BTI exception, avoid using the scavenged register
optimization when BTI is active (i.e., branchTargetEnforcement() is
true). This makes the compiler fall back to spilling X16, allowing the
linker to handle the long branch and insert the necessary BTI-compliant
veneer.

[libc++] Allow building libc++ using llvm-libc without locale support (#187603)
This PR allows libc++ to be configured to use LLVM-libc without
requiring locale-variants of libc functions.
This PR updates libc++ to use `<llvm-libc-types/mbstate_t.h>`
when building against LLVM-libc to avoid pulling in all of `wchar.h`.
There is some code duplication in this PR. The code in `formatting.h` is
similar to the implementation in `fuchsia.h`, except that the new code
does not use thread-local locales via `__locale_guard`:
https://github.com/llvm/llvm-project/blob/673002f32576ebac3953432ef12be64ca49d4361/libcxx/include/__locale_dir/support/fuchsia.h#L133
If reviewers would like, I'm happy to refactor to create more shared
headers, similar to how `no_locale` is set up. I've avoided doing so in
this PR, but lmk. It looks like there's three general ways these
passthrough functions are defined for unix systems:
- No locale (e.g. Fuchsia's `strtod` ignores locales entirely).
- Thread-local locale (e.g. other Fuchsia functions use `__locale_guard`
set up locales via `uselocale`).
- Native locale-specific function variant (i.e. the proxy just uses the
*_l variant, like `toupper_l`).

[libc] Validate against LC_ALL_MASK in newlocale (#194514)
Currently, `newlocale` uses `LC_ALL` for validation, but it's supposed
to the `LC_*_MASK` category of constants
(https://pubs.opengroup.org/onlinepubs/9699919799/functions/newlocale.html).
Pretty inconsequential since LLVM-libc doesn't actually support locales,
but this popped up since libc++ wants to be able to call `newlocale` and
not receive a `nullptr`.

[CIR] Fix DeleteArrayOp lowering for unsized delete with destructor (#194711)
`CIRDeleteArrayOpABILowering` asserts that `deleteParams.getSize()` must
be true when `elementDtorAttr` is set. This is wrong — a cookie is
needed for the destructor loop regardless of whether `operator delete[]`
takes a size parameter. With `-fno-sized-deallocation` (or C++14
defaults on some targets), you get unsized `::operator delete[](void*)`
with a non-trivial destructor, which hits the assertion.
Fix: set `cookieRequired` when either `getSize()` or
`getElementDtorAttr()` is true, and only compute/pass the allocation
size when `getSize()` is true.
Found while building the Eigen test suite with CIR.

[CIR] Relax end_catch assertion in flattenCatchHandler (#194917)
Follow-up to #193796. The end_catch predecessor walk in
`flattenCatchHandler` returned false on blocks with non-`BrOp`
terminators or non-`EndCatchOp` content before the terminator. Catch
handlers with control flow — e.g., try/catch inside a do-while loop with
a conditional return, as used by Eigen's SparseLU memory allocator —
produce conditional branches on the path after cleanup scope flattening,
tripping the assertion.
Relaxes the walk to continue through all predecessor paths and return
true when `end_catch` is found on any path, preserving the reachability
invariant.

[CIR] Fix array new cookie pointer arithmetic (#194927)
`initializeArrayCookie` calls `createPtrBitcast(ptr, u8PtrTy)` to get a
byte pointer into the allocation. `createPtrBitcast` wraps its argument
in `cir::PointerType`, so the result is `!cir.ptr<!cir.ptr<!u8i>>`
instead of `!cir.ptr<!u8i>`. The subsequent `cir.ptr_stride` by 8 then
advances by `8 * sizeof(ptr)` = 64 bytes instead of 8, placing the first
array element at the wrong offset. `delete[]` reads garbage from the
cookie and crashes with `free(): invalid pointer`.
Fix: `createBitcast` instead of `createPtrBitcast`, and `u8Ty` instead
of `u8PtrTy` in the `Address` constructor.

MC: Group .reloc directive relocations and emit groups in offset order.
The current behavior, where .reloc directives are added to the end of the
symbol's fragment's relocation list, is problematic because a fragment
can be split at an arbitrary point (e.g. due to exceeding FragBlockSize),
and if that point is in the middle of a relocation sequence such as
TLSGD, that can result in an invalid sequence being emitted.
To fix this, modify the behaviour to be closer to what GNU as does, by
maintaining a .reloc group for each fragment while inserting .reloc
relocations. A .reloc group is a consecutive sequence of .reloc
relocations that have an offset <= the first relocation's offset. A
relocation with offset > the first relocation's offset starts a new
group. Relocation groups are inserted in offset order using the offset
of the first relocation, but the source ordering of relocations within
the group is preserved.

[clang][deps] Use `ModuleFile` instead of `Module` (#194028)
This switches the dependency scanner from handling `Module` objects to
dealing with `serialization::ModuleFile`. Module file already contains
(almost) all of the information the scanner needs, and has the advantage
of not forcing deserialization of `Module` objects from PCM files, which
will become important in a later PR.
This alone improves clean scans by 1.8% and incremental scans by 2.6%.
This effect is likely caused by removing iteration over many `Module`
objects, removing deduplication via associative containers deduplication

[llvm-dwp] Replace MCStreamer with direct ELF writer for zero-copy output (#192112)
Replace the MCStreamer-based output pipeline with a lightweight direct
ELF writer (DWPWriter). Section data is stored as zero-copy StringRef
chunks pointing to the mmap'd input files, and written as a minimal
ELF64 relocatable object directly to disk.
## Rationale
The MCStreamer pipeline copies all section data into 16KB MCDataFragment
blocks, accumulates them in memory, then writes everything out during
MCAssembler::Finish(). This can be cause lots of memory pressure and
slow down llvm-dwp.
For instance, on a 3.3GB DWP file, this translates to rougly ~3.3GB of
heap allocation and two full copies of the data.
The new DWPWriter avoids this via:
- emitBytes() stores a StringRef chunk (zero-copy, no allocation)
- emitIntValue() writes to a small per-section buffer (index tables)
- writeELF() streams chunks directly from input mmap to output file
- for single-input DWP files, string deduplication is also skipped since
all strings are already unique. (minor optimization)
Bonus: this also removes all MC library dependencies from llvm-dwp
(AllTargetsCodeGens, AllTargetsDescs, AllTargetsInfos, MC,
TargetParser), reducing the binary size.
## Benchmark
I benchmarked on a 3.3GB production DWP file (8638 CUs, ~981MB
.debug_str.dwo):
Results:
Before: 23.6s wall (19.6s user, 3.9s sys)
After: 6.0s wall (3.0s user, 2.9s sys)
**3.9x** wall time improvement, 6x fewer page faults (178K vs ~1M).

[dsymutil] Fix ODR type uniquing for -gsimple-template-names (#194501)
With -gsimple-template-names (now the default on macOS with deployment
target >= 26), template types like vector<int> and vector<float> both
get DW_AT_name("vector") in DWARF, with template parameters encoded only
as DW_TAG_template_type_parameter children.
Previously, dsymutil used only DW_AT_name for ODR type uniquing, causing
different template specializations to collide. This PR fixes that by
reconstructing template parameter information from child DIEs when the
type name does not already contain template parameters.
The reconstructed name is used only for uniquing and not emitted into
the output DWARF. The parallel DWARF linker already handled this
correctly via SyntheticTypeNameBuilder.

[CIR] FlattenCFG: accept cir.trap as a ternary region terminator (#194497)
The CIRTernaryOpFlattening pattern only accepted cir.yield and
cir.unreachable as the terminator of a ternary region. Any other
terminator caused a verifier error ("unexpected terminator in ternary
false region") and aborted the backend with "IR failed to verify after
pattern application".
Real-world C++ code that uses the libc++ assertion macros hits this
path: _LIBCPP_ASSERT_NON_NULL expands to `cond ? (void)0 :
__builtin_trap()`, which lowers to a `cir.ternary` whose false region
ends in `cir.trap`. This is structurally identical to the
`cir.unreachable` case (both are non-returning Terminators), so the
flattening pattern just needs to leave the trap in place rather than
trying to rewrite it into a branch to the continue block.
Concretely this is blocking ~1,510 libc++ tests (~17% of the suite) that
all failed with the same diagnostic at construct_at.h, sample.h, and
pop_heap.h.
Extends clang/test/CIR/Transforms/ternary.cir with regression coverage
for cir.trap (true and false region) and cir.unreachable (false region).

[MemProf] Skip GV `__prof*` during instrumentation (#193354)
The existing filter in `isInterestingMemoryAccess` skips globals named
`__llvm*`, but PGO counter globals are named `__profc_*` (and related
`__profd_*`, `__profvp_*`, etc.), so they bypass the name check, e.g.:
https://github.com/llvm/llvm-project/blob/b48d8a54e29f5f33ef52a4759414126904f01611/llvm/include/llvm/ProfileData/InstrProf.h#L128-L138
The section-based check above catches direct accesses where
`stripInBoundsOffsets` resolves to the GlobalVariable, but fails for
bias-based counter addressing `(inttoptr(add(ptrtoint(__profc_),
bias)))` which the strip cannot see through.
This causes MemProf to instrument PGO counter updates, inflating MGO
binary access profiles proportionally to __llvm_prf_cnts section size.
Filtering `__prof` prefixed globals closes this gap.
RFC: we have confirmed `__prof*` are dead weight, whether we should
block `llvm.*` like `InstrProfiling.cpp` did is an open question for ppl
familiar with MemProf, e.g.:
https://github.com/llvm/llvm-project/blob/b48d8a54e29f5f33ef52a4759414126904f01611/llvm/lib/Transforms/Instrumentation/InstrProfiling.cpp#L1518-L1521

Many of these pseudos are emitted from codegen meaning they aren't

[WebAssembly] Remove WasmEHFuncInfo (NFC) (#194972)
This removes `WasmEHFuncInfo` class.
This class was created to maintain the information of, "If an exception
is not caught by EHPad A, what is its next unwind destination?". Turns
out this information is already in the CFG.
After #130374, we use the common `findUnwindDestination`:
https://github.com/llvm/llvm-project/blob/113479d119a997e4c4c3eae63e087588c9662121/llvm/lib/CodeGen/SelectionDAG/SelectionDAGBuilder.cpp#L2107-L2164
Note that in case of `catchswitch`, we follow its unwind destination
chain and add all of them to the invoke BB's successors until it meets a
`cleanuppad`, which always catches an exception. And the order of the
successor is the order of the unwind destination chain. So an invoke
BB's successor list would be like: [normal destination, unwind EHPad 1,
unwind EHPad 2, unwind EHPad 3, ...] where EHPad 2 is the next unwind
destination if EHPad 1 does not catch an exception and so on. So if we
want to know what the current EHPad's next unwind destination is, we can
examine the EHPad's predecessor (invoke BB)'s successor list, and find
the next successor of EHPad. If there is no further next unwind
destination, the list should end with that EHPad.
How we do this is in the added lambda functions in CFGStackify, which
replaces `WasmEHFuncInfo`'s `hasUnwindDest`/`getUnwindDest`.
This depends on the order of successors of a CFG, which someone can
argue may be not guaranteed, in case someone messes up the successor
order in later passes. But I think in practice this should be fine. Also
maintaining `WasmEHFuncInfo` has more risks, because if other passes
change EH-related CFGs, they have to make sure `WasmEHFuncInfo` stays
synced. I haven't personally found (so far) those passes and haven't had
to any adjustments to other passes, but it was always an inherent risk
when you maintain a separate data structure.
I wasn't able to completely delete `WasmEHFuncInfo.h` because it
contains the `Tag` enum. I renamed it to `WasmEHInfo.h`, because we
dont' have `WasmEHFuncInfo` class anymore.

[orc-rt] Add NativeDylibManager. (#194792)
NativeDylibManager is an orc_rt::Service that supports loading,
unloading, and lookup of symbols via the system dynamic loader's native
APIs.
The current implementation only supports the POSIX dlfcn.h APIs (dlopen,
dlclose, dlsym), but it should be straightforward to extend to Windows.

[mlir][python] expose remaining Location inspection API (#192630)
Addresses #53169. Mirrors the Python bindings pattern used for Attribute
subclasses so that Location discrimination uses `isinstance`, and fills
two small gaps at the same time.
### Approach
Previously `Location` was a single nanobind class with `is_a_file`,
`is_a_name`, etc. predicates, plus field accessors for every kind
defined on the base class. This PR introduces a `PyConcreteLocation<T>`
CRTP template (parallel to `PyConcreteAttribute<T>`) and registers one
subclass per `LocationAttr` kind: `UnknownLoc`, `FileLineColLoc`,
`NameLoc`, `CallSiteLoc`, `FusedLoc`.
TypeID-based downcasting is implemented in `PyLocation::maybeDownCast`
(using `mlirAttributeGetTypeID(mlirLocationGetAttribute(...))`) and
called at the boundaries that return Location objects: `op.location`,
`value.location`, `Location.from_attr`, and the subclass getters
themselves.
### Example
```python
from mlir.ir import Context, Module, FileLineColLoc, NameLoc, FusedLoc
with Context():
module = Module.parse("...")
for op in module.body.operations:
loc = op.location
if isinstance(loc, FileLineColLoc):
report(f"{loc.filename}:{loc.start_line}:{loc.start_col}")
elif isinstance(loc, NameLoc):
report(loc.name_str)
elif isinstance(loc, FusedLoc) and loc.metadata is not None:
report_fused(loc.locations, loc.metadata)
```
`FusedLoc.metadata` is also newly exposed (the underlying C API
`mlirLocationFusedGetMetadata` already existed but was not bound).
### Custom/downstream Location classes
`PyConcreteLocation<DerivedTy>` is marked `MLIR_PYTHON_API_EXPORTED` and
is used identically to `PyConcreteAttribute<DerivedTy>`. Downstream
projects that define their own `LocationAttr` in C++ expose a matching
Python class by declaring a subclass with the standard statics
(`isaFunction`, `pyClassName`, optional `getTypeIdFunction`) and calling
its `bind(m)` at module init; `isinstance` and automatic downcasting
then work with no further changes in the base bindings.
### Backward compatibility
Existing factories — `Location.unknown()`, `Location.file(...)`,
`Location.name(...)`, `Location.callsite(...)`, `Location.fused(...)` —
remain as aliases and now return the concrete subclass instance (so
`isinstance(Location.file(...), FileLineColLoc)` is true). No user
migration is required for construction.
The old `is_a_*` predicate methods are removed; downstream consumers
should switch to `isinstance(...)`. No in-tree users of the removed
predicates besides the existing Location tests, which have been
rewritten accordingly.
### Scope note — OpaqueLoc
OpaqueLoc is intentionally not included. It is keyed on a C++
`TypeID::get<T>()` tag that has no natural Python counterpart, and I
could not find a downstream consumer asking for Python exposure. An
earlier revision of this PR exposed it with an `id(obj)` + `ctypes.cast`
example, but that pattern is lifetime-unsafe (MLIR does not INCREF the
underlying pointer) and the C++ `getUnderlyingLocation<T>()` semantics
don't translate cleanly. Happy to add it in a follow-up once a real use
case surfaces.
### Changes
C API (`mlir/include/mlir-c/IR.h`, `mlir/lib/CAPI/IR/IR.cpp`):
- `mlirLocationIsAUnknown`, `mlirLocationUnknownGetTypeID` — other
Location kinds already had their `IsA*`/`*GetTypeID` pair.
Python (`mlir/include/mlir/Bindings/Python/IRCore.h`,
`mlir/lib/Bindings/Python/IRCore.cpp`):
- `PyConcreteLocation<T>` template and five concrete classes
- `PyLocation::maybeDownCast`
- Subclass `.get()` constructors, `.metadata` on `FusedLoc`
Tests:
- `mlir/test/python/ir/location.py` rewritten around `isinstance` and
subclass construction; adds explicit-cast-failure coverage.
- `mlir/test/CAPI/ir.c` adds `testLocation` covering the new
`mlirLocationIsAUnknown` predicate.
### Tool-use disclosure
This change was drafted with Claude (Anthropic) assistance per LLVM's
[AI Tool Use Policy](https://llvm.org/docs/AIToolPolicy.html). All code
was read, reviewed, and tested locally by me; the commit carries

[mlir][emitc] Deferred emission as expressions (#159975)
The translator currently implements deferred emission for certain ops.
Like expressions, these ops are emitted as part of their users but
unlike expressions, this is mandatory. Besides complicating the code
with a second inlining mechanism, deferred emission's inlining is
limited as it's not recursive.
This patch extends EmitC's expressions to deferred emission ops by (a)
marking them as CExpressions, (b) extending expression interface to mark
ops as always-inline and (c) support inlining of always-inline
CExpressions even when not packed of an `emitc.expression` op, retaining
current behavior.

The Process class is the one responsible for managing the state of a
BreakpointSite inside the process. As such, it should be the one
answering questions about the state of the site.
Future patches will make this even more important by introducing a

The location of hlfir.where operations was not set correctly (left to
the location of the previous statement of construct).
Fix this and add test.
While doing so, I noticed the bridge current location was not set
consistently when entering constructs. While this usually was OK because
no code was emitting in many case before visiting an inner construct,
there was at least one case where this lead to bad location for OpenAcc
atomic. Hence I updated all construct that did not call
`setCurrentPositionAt` to do it, this seems more future proof.

[SelectionDAG] Reland debuginfo salvage for load/ext combines (#194700)
This relands fe5d5b762ab3b92b18b56f413965abb81a459ac6, which salvages
debug info when folding load and zext/sext patterns in SelectionDAG.
Salvage debuginfo when combining load and z|s ext instrs.
SelectionDAG uses the DAGCombiner to fold a load followed by a sext to a
load and sext instruction. For example, in x86 we will see that
```
%1 = load i32, ptr @GlobArr
#dbg_value(i32 %1, !43, !DIExpression(), !52)
%2 = sext i32 %1 to i64, !dbg !53
```
is converted to:
```
%0:gr64_nosp = MOVSX64rm32 $rip, 1, $noreg, @GlobArr, $noreg, debug-instr-number 1, debug-location !51
DBG_VALUE $noreg, $noreg, !"Idx", !DIExpression(), debug-location !52
```
The `DBG_VALUE` needs to be transferred correctly to the new combined
instruction, and it needs to be appended with a `DIExpression` which
contains a `DW_OP_LLVM_convert` expression, which correctly casts the
value in the virtual register to the correct size.
This patch fixes the above described problem.
The patch also accounts for multiple DW_OP_LLVM_arg's in a DIExpression
which had caused it to break tests on the sanitizer-x86_64-linux bot but
has now been fixed, with an added testcase called
selectionDAG-load-zext-multiple-args.ll which was reduced from the
broken test itself.
fe5d5b762ab3b92b18b56f413965abb81a459ac6 exposed a crash in
tryToFoldExtOfLoad(), which is described in
https://github.com/llvm/llvm-project/issues/193475
Fix that by replacing the folded node before deleting or rewriting the
old nodes, and by transferring debug values before entering the
replacement path.
Add an X86 regression test for the extload combine crash.

[mlir][linalg] Fuse transform op - variadic tile sizes (#194657)
Extends the 'structured.fuse' op to accept packed handle containing
variable number of tile sizes.
Use of packed handles allows for runtime tiling decisions for improved
transform schedule flexibility and reusability.
The extension's design follows the existing approach of transform
'structured.tile_using_forall' op to more closely align their usage.
In case of tiling using nested loops, all created loops are packed into
a single return handle. For each target op, corresponding loops are
appended to the result handle.

[LICM] Improve hoist-safety checks for dominated MemorySSA accesses (#169379)
This changes LICM's hoist-safety check in `noConflictingReadWrites()`.
When considering a `MemoryDef` for hoisting, LICM now skips in-loop
accesses that are already dominated by that `MemoryDef`:
```c++
if (!Flags.getIsSink() && MSSA->dominates(IMD, &MA))
continue;
```
Dominated accesses should not block hoisting, because they already
execute after the candidate instruction `I` and therefore already see
its effect. Non-dominated accesses can block hoisting, because they may
execute before the candidate `I` and observe a different memory state
after hoisting.
The tests are updated to cover the new behavior, including
store-hoisting, call-hoisting, guards, `llvm.invariant.start`, and
inaccessible-memory call cases, along with the corresponding MemorySSA
check updates.

[mlir] Refactor transform.apply_dce into a eliminateTriviallyDeadOps region-utils helper and expose as a Pass (#194041)
Introduce a lightweight, targeted dead-op eliminator that complements
the
existing liveness-based runRegionDCE. The algorithm is O(ops):
step 1 walks each op in reverse program order, erases it outright if
trivially dead, or recurses into nested regions when recursive cleanup
is
enabled; step 2 drives a per-region worklist that only ever holds ops
already verified dead, propagating new deadness by dropping each
operand's
use before re-checking isOpTriviallyDead on the defining op.
Unlike runRegionDCE, this does not touch dead block arguments, dead
successor operands, or dead use-def cycles. Use runRegionDCE when those
are required. An includeNestedRegions parameter lets callers restrict
simplification to the top-level region.
Switch transform.apply_dce to use the new helper, dropping a custom
worklist that had subtle invariants: SetVector dedup, linear search on
every erase, and pre-order walk with skip.
In general it is bad practice to implement complex custom logic in
Transform ops apply methods: this should be an adaptor exposing MLIR
transformations to the transform dialect; non-trivial logic deserves a
public API for reusability and proper layering.
Introduce a TrivialDeadCodeEliminationPass exposed as -trivial-dce. The
pass
removes trivially dead operations and, when removeBlocks is enabled,
unreachable blocks. It does not run liveness analysis and does not
remove
dead use-def cycles. Add recursive and removeBlocks options, both
defaulting
to true, to control whether nested regions are visited and whether
unreachable blocks are erased.

The header does three things:
- it defines `__STDC_FORMAT_MACROS` for compatibility with glibc
versions we don't support anymore
- it includes `<stdint.h>`, which is already required to be included by
the C standard
- it `#undef`s two macros which might be defined by the libc. We don't
provide a `<stdint.h>` header ourselves, which might provide these
macros as well, so these are already not defined by any libcs we
support.
So this header should be safe to remove.

llvm: Use add_link_options for stack size flags (#195034)
Previously, LLVM was directly editing `CMAKE_EXE_LINKER_FLAGS`. This is
a user-facing CMake cache variable not meant to be modified by project
code. This was causing issues for downstream consumers building
non-C/C++ targets as part of the LLVM build.
Modern CMake provides `add_link_options()`, a cleaner way to set linker
flags that propagate to every target in a directory tree.
Generator expressions and the `LINKER:` prefix syntax ensure that this
is only applied to executable targets with the proper language and
linker argument wrapping.

[SCEV] Limit ControlsOnlyExit logic to BinOps with neutral elements. (#194831)
As far as I can tell, ControlsOnlyExit is used during reasoning to
assume
that we stay in the loop as long as the condition is true/false, and are
guaranteed to exit otherwise.
But unless I am missing something, a sub-condition of an AND/OR never
solely controls the exit, whether we exit always depends on both
conditions.
Pass false to ControlsOnlyExit, as otherwise we would incorrectly assume
that we must exit if either conditions is true, when we would only exit
if both are true.
For now, ControlsOnlyExit is only used for the neutral element case, it
may be worth removing this.

recognize cases where only one child is same-opcode and one-use like
max(max(a, b), c) feeding another max.
For example, with R = max(max(A, B), C) where A, B, and C are each
ternary chains of the form max(max(x, y), z), the current predicate does
not recognize the ternary-chain interiors as still combinable, so the
higher-level rules fire eagerly and produce max3 nodes with 2-op maxes
inside them. With the extended predicate, each ternary chain is allowed
to fold into a max3 first, after which the higher levels reduce cleanly
without leaving stranded 2-op maxes behind.
Adds six regression tests covering a 2-level ternary chain, a mixed
ternary+binary shape and vector examples.

[ObjCopy] Reject compress-debug-sections for non-ELF (#191314)
`--compress-debug-sections` is currently an ELF-only option in the

`--compress-debug-sections` and `--compress-sections` as unsupported for non-ELF formats too.

[LoopInterchange] Fix handling of PHI which refers to another PHI (#194364)
In the transformation phase, at first LoopInterchange moves several
instructions in the inner loop into the new latch block. The
instructions used as incoming values to the induction variables from the
latch block are the targets of this movement. Previously, this process
could result in an infinite loop when a PHI node refers to another PHI
node, as in the following example:
```
%i = phi i64 [ 0, %entry ], [ %i.inc, %latch ]
%j = phi i64 [ 0, %entry ], [ %i, %latch ]
```
The root cause was that `%i` enqueued for processing because it is used
by `%j`.
This patch fixes the issue by preventing induction variables from being
enqueued into the movement list.

[clang][unittests] Fix flaky PerformPendingInstantiations nesting in TimeProfilerTest (#193717)
buildTraceGraph already compensates for timer rounding that makes
PerformPendingInstantiations appear to be inside the previous event, but
only when it is nested exactly one level deep. The aarch64-darwin
buildbot produced three-level nesting for ConstantEvaluationC99, which
slipped through the normalization and broke the expected trace output.
Keep popping while PerformPendingInstantiations looks nested—we know it
is always a top-level event in these tests—instead of stopping at the
single-level case.

Replace the two-CSINC scan with a single forward walk maintaining a
DenseMap keyed by canonical (copy-traced) register. Any number of pairs
per block are now handled.

verifier now rejects mismatches up-front, and the Python op-binding

`nvvm.ThreadIdXOp()` with no arguments. Strict tightening: no valid

This was previous put here for ergnomics as to put it in the template
required decltype. However, this has the effect of putting an actual
functoin pointer in an escaping context if it is not fully removed or
inlined. C++17 has a non-type-template parameter that we can use to
keep the interface clean. Use that instead.

[DAGCombiner] Reconstruct borrow chain from icmp pattern for USUBO_CARRY (#193707)
DAG-level alternative to #189018 (CGP): match the canonical icmp form
carry_out = or(icmp ult A, B, and(icmp eq A, B, carry_in))
in visitOR and rewrite to USUBO_CARRY so the backend can chain the
borrow through sbb/sbcs.
Gated on USUBO_CARRY being legal/custom at the type the integer
legalizes to, so targets without hardware carry-flag support are
unaffected. For oversize integers (e.g. i128 on x86_64/aarch64) type
legalization then expands one USUBO_CARRY into a chain of
register-width USUBO_CARRYs, which gives strictly better code than the
CGP-level reconstruction.
Fixes #106118.

[mlir][dataflow] Register dependency when const-prop fold returns non-operand (#194372)
Fixes #137509.
When `op->fold` returns a Value that is not one of `op`'s operands (e.g.
`unrealized_conversion_cast`'s fold returns the inner cast's operand),
`SparseConstantPropagation` read that value's lattice without
subscribing to it -- so the op was not revisited when the lattice
widened and its stale fold result was not updated.
Fix by using `getLatticeElementFor(getProgramPointAfter(op), v)` to
register the dependency. This matches a few places in
`SparseAnalysis.cpp` where the same strategy is used.
I'd love to use something even simpler than `unrealized_conversion_cast`
operation in the test, but this is what i got when minimizing the
reproduction from the original issue (#137509) and i wasn't able to find
any operation that would work for this reproduction.

Fix memcpy-operator= generation with restrict parameters. (#194906)
The below issue (and #63884) both report that we reject (and also
assert, because the memcpy failed) the memcpy we're generating for a
restrict field of a type with an implicit copy constructor.
First, we shouldn't be rejecting it this late, IF we wanted to reject it
(I contend we do not), we should do it at the same time we reject
const-members/make this a deleted operator. Second, of course we
shouldn't fail.
This patch NOW works by just having us skip the premature 'memcpy'
optimization here. In the end, the memcpy is generally skipped by
`CodeGenFunction::EmitCXXMemberOrOperatorMemberCallExpr` in the example
(as this is a trivial type), but this reverts it to using a 'for' loop
for restrict, as it does for const, and volatile qualified values.
We perhaps might think about doing this for address-spaces/ptr-auth, but
at the moment, this fixes restrict version.

tryReduceVL may need to move an instruction to make the VL dominate. If

Rewrite the code to use iterators so we will get an end iterator
instead. Replace the call to MachineInstr::moveBefore with the
equivalent MachineBasicBlock::slice which works on iterators.

[libc] Stop passing `--version` to compiler when detecting target (#176680)
This reverts c267501c155f9, and also adds a `-c` flag.
Both gcc and clang print the `Target:` line that we're trying to find
just find with just `-v`.
When passing `--version`, gcc passes `--version` to the system linker,
and when using gcc on macOS, the system linker does not understand
`--version`. Since `--version` does not seem to be necessary, drop it.
Also, passing `-c` lets gcc not print linker details, so add that too,
as a belt-and-suspenders fix.

[RegisterCoalescer] Fix incorrect VNInfo deletion condition in pruneSubRegValues (#195023)
Fixes https://github.com/llvm/llvm-project/issues/156249
Guard markUnused in subrange pruning so that only VNInfos defined at the
COPY being
erased are marked unused, preventing incorrect removal of still-live
values in subregister/lane-based intervals.

[AtomicExpandPass] Preserve atomic and volatile nature of emulated operations (#188361)
The fix does the following in expandPartwordCmpXchg and
insertRMWCmpXchgLoop.
- Issues volatile operations in the emulation loops if the original
operation is volatile.
- A preheader load is used for initializing the "cmp" and "new" values
of the cmpxchg in the loop. Makes this load atomic. This is done under a
target hook (`issueAtomicInitLoadForAtomicEmulation()`) , to allow
backends to migrate independently.
- `processAtomicInstr` is called on this load, to massage it into
something that can be lowered in SelectionDAG / GISel.
- This caused 3 kinds of failures.
1. Caused by change to codegen: updated these either using the scripts,
or mechanically (using claude) to match the new codegen.
2. Crashes caused by newly created atomic loads not being processed by
AtomicExpandPass. (The atomic load if tested in an independent test does
not cause a crash). To fix these, added recursive calls to
processAtomicInstr on the newly created atomic loads. These calls
convert the loads to libcalls, or cast them to integer types.
3. Crashes in X86, AMDGPU, and AArch64 caused by unhandled vector types.
These loads crash even with upstream LLVM, due to the lack of support in
these targets for vector atomic loads (the corresponding vector
atomicrmw instructions are supported). Disabled issuing atomic loads for
these backends. Will follow up with individual PRs to revert to default
behavior.

Add support for specifying the null pointer bit representation per

- 'z': null pointer is all-zeros
- 'o': null pointer is all-ones
When neither flag is present, the null pointer value is zero.
No target DataLayout strings are updated in this change. This is pure

support targets with non-zero null pointers (e.g. AMDGPU).

[DAGCombiner] Teach `reduceLoadWidth` to look past `ISD:FREEZE` (#189317)
Teach `DAGCombiner::reduceLoadWidth` to look through freeze SDNodes when
narrowing loads. The narrowed result is then wrapped in freeze to
preserve the original semantics. Currently, several folds were blocked
by the freeze:
```
and(freeze(load), 0xff) -> AssertZext(freeze(zextload, i8))
trunc(freeze(load i32), i8) -> freeze(load i8)
sext_inreg(freeze(load), i8) -> AssertSext(freeze(sextload, i8))
```
and many other patterns due to legalizer or upstream IR passes inserting
freeze. This generally has the positive effects of narrowing the load
type.

[clang][deps] Call getMemBuffer with RequiresNullTerminator false (#195072)
The getMemBuffer() has a default parameter RequiresNullTerminator which
is set to true.
In ModuleCache the MemoryBuffer::getOpenFile is called with /*
RequiresNullTerminator=*/false. This means that initial contents of the
MemoryBuffer may not have a trailing 0x0 at the end of the file.
When assertions are enabled and RequiresNullTerminator is true the
MemoryBuffer will trigger a "Buffer is not null terminated!" assertion
failure if BufEnd[0] != 0.
We have at one build with assertions enabled that is triggering this
MemoryBuffer assertion failure in the check-clang tests:
* ClangScanDeps/modules-dep-args.c
* Driver/modules-driver-import-std.cpp
The failure is specific to one particular machine, we have not been able
to reproduce locally. It is possible that the failure is filesystem type
or path length dependent.
Changing the RequiresNullTerminator in getMemBuffer to false to match
the value of RequiresNullTerminator in getOpenFile fixes the problem and
all tests pass.

[Inliner] Use store-to-load forwarding to resolve call arguments (#190607)
Uses `FindAvailableLoadedValue` to resolve load instructions in call
arguments to constants before inline cost analysis. This gives the
inliner more precise cost estimate and option to inline functions which
would not be inlined otherwise.
The `-O3` doesn't inline empty `std::set` and `std::map` because node
deletion is recursive. The inliner doesn't know that `nullptr` is passed
in as it is a `load` from a member.
This addresses both `libstdc++` and `libc++`:
- `libstdc++` - `FindAvailableLoadedValue` requires `MaxInstToScan=0`,
because relevant store is 7 instructions away and `DefMaxInstsToScan =
6`. Benchmarking on large LLVM TUs showed no measurable compile-time
difference between limit=6 and whole basic block
- `libc++` - uses `memset` to zero all members in ctor, this patch
handles only `memset` to zero (the type mismatch case), which could be
generalized but seems very rare
The store-to-load pattern is created and consumed within the same CGSCC
inliner invocation: the ctor is inlined first (creating stores to the
object), and then the dtor's inline cost is evaluated (seeing loads from
the same object). No pass has an opportunity to simplify the IR in
between.
The `-flto` build eliminates empty `std::set` because the IR is
simplified enough in the regular optimization pass. However, when the
code is not header-only in a different TU, `-flto` doesn't help.
The change is much more general than just `std::set` and `std::map`. I
saw several impacts of it on LLVM codebase with `-O3`. Some function
reduce in size due to better dead-code elimination. Some increase due to
more aggressive inlining opportunities, and some are greatly simplified.
In my experiments I saw no measurable regression in compile times
compiling many large LLVM TUs. I measured ~1% faster compilation due to
following opt passes being faster. However, this needs more benchmarks.

[AMDGPU] Add readfirstlane for inline asm SGPR with VGPR input (#176330)
SIFixSGPRCopies was incorrectly handling inline assembly operands with
SGPR ("s") constraints when the value came from a memory load (which
produces a VGPR). The pass would fail to insert the necessary
v_readfirstlane instruction instead directly passes the vgpr value.
example:
asm sideeffect buffer_load_dwordx4 $0, $1, $2, 0 =v,v,s,n
previously it generated:
buffer_load_dwordx4 v[0:3], v0, v[8:11] (but sgpr is expected), 0 offen
The fix adds readfirstlanes during lowering when there is a copy from
divergent register to SGPR.

[DWARFLinker] Make ODR uniquing deterministic (#194777)
The parallel DWARF linker deduplicates types across compile units using
a shared TypePool. When multiple CUs define the same type,
allocateTypeDie uses compare_exchange_strong to race for setting the
canonical DIE. The first thread to succeed stores the DIE and clones its
attributes, while subsequent threads use it the canonical one. Which
thread wins depends on OS thread scheduling, making the output
non-deterministic.
This PR fixes the non-determinism by assigning each CompileUnit a
priority based on its position in the link order (object file index, CU
index within the file). When a CU wants to mark DIE as canonical, it
acquires the spinlock, and only stores its DIE if its priority is
strictly lower than the current canonical DIE. This ensures that the
canonical DIE is always the lowest-priority (i.e. first) CU that defines
that type. The replaced DIE is leaked into the bump allocator and the
existing DebugTypeDeclFilePatch and accelerator record filters skips the
orphaned DIEs via getFinalDie() checks.
This PR also removes the AllowNonDeterministicOutput option, which was
never set in the first place, and is now obsolete.

[mlir][ABI] Add ABITypeMapper and ABIRewriteContext (#190661)
Add ABITypeMapper and ABIRewriteContext as the dialect-agnostic
bridge between MLIR dialects and the LLVM ABI Lowering Library.
ABITypeMapper maps MLIR built-in types (integer, float, vector,
index, memref) to abi::Type* using DataLayout for sizes and
alignment. Dialect-specific types fall back to integer mapping
via DataLayoutTypeInterface.
ABIRewriteContext defines the abstract interface that each dialect
(CIR, FIR) implements to rewrite function definitions and call
sites after ABI classification. See the CIR ABI lowering design
document (clang/docs/ClangIRABILowering.md, Section 4) for the
architectural context.
Unit tests for both components (18 test cases).

[clang] teach OpenCL to set the param addrspace before calling CG EmitParmDecl (#184264)
Unfortunately, this still ends up in a slightly awkward place between
Sema and CG, since a few CG phases create implicit parameters (e.g. for
`this`) which also need to be deduced into the correct address space by
Sema. This is intended to be clearly extensible for other targets that
also need this.
Changes the constructor for ImplicitParamDecl to be private again, so
that all users will go through the Create method, by making the object
ctor itself declared `protected` (like all the other VarDecl subtypes).
The memory is later cleaned up by the ASTContext bump allocator, and
since the stack is basically also a bump allocator, is is typically
equally fast. (Reverts 550d13aebbcc03806811a3aa08e674b9b84e08e8)
(If I got my commit stacked extraction right) This should allow removing
the special cases for OpenCL from EmitParmDecl once
https://github.com/llvm/llvm-project/pull/181390 lands, since this
aligns the behavior of that function with the declared intent of each
VarDecl.
This changed many tests because previously OpenCL just assumed that
allocations for parameters were actually made in the addrspace of Ty,
but didn't actually check against that properly, resulting in some
unnecessary copies. That will be fixed even more completely in
https://github.com/llvm/llvm-project/pull/181390 even more, removing
also the unnecessary addrspace casts.

[LLDB][Part 1] Support enabling/disabling InstrumentationRuntime plugins in an debug session (#193328)
This patch is the first part in a patch series that will allow
enabling/disabling InstrumentationRuntime plugins in a running debug
session.
This part adds the `--domain` flag to the `enable`, `disable`, `list`
sub commands of `plugin` shell command and plumbs the value of this flag
to where it will be needed in a subsequent patch. From the user
perspective the flag does nothing useful yet because all values passed
to the flag except `global` (the default and what represents LLDB's
existing behavior) are rejected. Subsequent patches will allow the flag
to do something useful.
The `--domain` flag adds a notion of "domain" to plugins with respect to
their enablement. Previously all plugins were treated as global and have
their enablement stored globally. This is despite the fact that some
plugins clearly are not global. For example the
`instrumentation-runtime` plugins clearly exist on a per-target basis
(the instances of the `InstrumentationRuntime` exist in each process).
In addition to this plugins being "global" means instances of the
`Debugger` instance are not properly isolated from each other. This PR
is a stepping stone towards fixing these design problems. The PR
introduces three different domains for plugins:
* `global` - Enablement of the plugin can be controlled globally. This
is the existing behavior of all LLDB plugins.
* `debugger` - Enablement of the plugin can be controlled on a per
`Debugger` basis.
* `target` - Enablement of the plugin can be controlled on a per
`Target` basis.
These values are encoded in the new `PluginDomainKind` enum.
It is important to note that the design in this PR means a plugin can
support more than one domain. In particular in future patches when
`instrumentation-runtime` plugins gain support for more than just the
`global` domain they will support the `debugger` and `target` domain as
well. The key reason that the `instrumentation-runtime` plugins need to
support more than one domain is that the plugins need a default
enablement value **before** the target exists. That default value will
need to come from the `global` domain. Architecturally it should
probably come from the `debugger` domain instead but refactoring
enablement into Debugger instances is much too large a refactor for this
patch series and is a problem that can be tackled later.
This patch modifies the `PluginNamespace` struct to:
* Store the set of domains supported by the namespace and provided some
helper methods to determine what is supported.
* Store one of two callbacks. Either `SetPluginEnabledGlobalDomain` (the
existing function interface used by most plugins) or
`SetPluginEnabledAllDomains` (a new interface used by
`InstrumentationRuntime` plugins).
In this patch the `InstrumentationRuntime` plugins use the new
`SetPluginEnabledAllDomains` function interface for enablement (i.e. the
interface of `PluginManager::SetInstrumentationRuntimePluginEnabled` has
changed) which passes the `Debugger` instance that made the request and
the domain the user provided to the `plugin enable` or `plugin disable`
command.
To make this patch easier to review the
`PluginManager::SetInstrumentationRuntimePluginEnabled` function
actually rejects all domains except `global` to keep the behavior change
down to a minimum. Proper support for enabling/disabling
instrumentation-runtime plugins in the `target`, and `debugger` domains
will be implemented in a subsequent patch.
The `plugin list` command implementations also reject any domain that
isn't `global`. Support for other domains will be added in the
subsequent patch that adds support for other domains in the
`instrumentation-runtime` plugins.
The `plugin enable`, `plugin disable`, `plugin list` commands will use
the `global` domain by default so that there is no behavior change for
existing workflows.
Two new shell tests are included that exercise the new code paths:
* `command-plugin-enable-disable-domain-flag.test` validates that
`--domain global` works for both global-only and multi-domain plugin
namespaces, and that `--domain debugger` and `--domain target` are
correctly rejected for now.
* `command-plugin-list-domain-flag.test` validates the same behavior for
the list command in both text and JSON output modes.
I am not experienced at adding flags to LLDB shell commands so I had
Claude Code write that part and also help write test cases.

[NFC][LLDB][Part 2] Support enabling/disabling InstrumentationRuntime plugins in an debug session (#193331)
This patch is the second part in a patch series that will allow
enabling/disabling InstrumentationRuntime plugins in a running debug
session.
This patch contains a set of NFC changes that will be needed when
implementing support for enabling/disabling InstrumentationRuntime
plugins in the `debugger` and `target` domains.
In particular
* In several places the `PluginManager` was modified to get access to
information about disabled plugins. Previously interfaces would only
return information about enabled plugins.
* `InstrumentationRuntimeInstances` is now struct rather than a typedef
so it can contain a helper method that allows looking up a
`InstrumentationRuntimeGetType` callback based on the plugin name. This
is very similar to the existing `PluginsInstances::GetCallbackForName`
method.

the man page is running on a kernel that does not support the system

Using Python's built-in help shows an empty screen when the statusline

nice with the statusline. Use the "plain" pager instead.
I considered making this conditional on the statusline, but to do that
right you would need to register a callback that toggles it every time
the setting changes and that doesn't seem worth the complexity.

[mlir][acc] Capture explicit serial semantics for compute regions (#195158)
This PR improves robustness in capturing when user's intent is to treat
OpenACC region as sequential. It does so in the following ways:
- Ensure that `seq` acc.par_width is explicitly used when region is
serial. Previously it was not assigning any acc.par_width which causes
ambiguities because that way it is indistinguishable whether a region is
explicitly serial vs whether the region needs implicitly assigned
parallelism.
- Treas `acc parallel` and `acc kernels` with `num_gangs(1)`
`num_workers(1)` `vector_length(1)` exactly the same as `acc serial`.
This is because these are all parallelism dimensions expressible with
OpenACC clauses and being all set to 1 makes the semantics consistent
with those defined for `acc serial`.

[dsymutil] Fix ODR type uniquing for -gsimple-template-names (#194501) (#195174)
With -gsimple-template-names (now the default on macOS with deployment
target >= 26), template types like vector<int> and vector<float> both
get DW_AT_name("vector") in DWARF, with template parameters encoded only
as DW_TAG_template_type_parameter children.
Previously, dsymutil used only DW_AT_name for ODR type uniquing, causing
different template specializations to collide. This PR fixes that by
reconstructing template parameter information from child DIEs when the
type name does not already contain template parameters.
The reconstructed name is used only for uniquing and not emitted into
the output DWARF. The parallel DWARF linker already handled this
correctly via SyntheticTypeNameBuilder.
This reland removes an overly strict assertion when clang emits
DW_TAG_subprogram DIEs with a demangled template-like DW_AT_name (e.g.
foo<int>) but no DW_AT_linkage_name. The surrounding logic already
handles this case correctly — it sees the name already contains template
parameters and uses it as-is for uniquing — so the assertion was simply
wrong. Added a regression test covering both the classic and parallel
linkers.

[clang][modules] Make -fmodules-decluse work on the public/private pair of modules (#192585)
Previously, it would only check the main module.
Now, if the main module is a private module (foo_Private), it will also check the public module.

[lldb] Remove verbose DWARF spec comments from evaluator (NFC) (#195140)
Most labels in DWARFExpression::Evaluate have a 3-10 line
OPCODE/OPERANDS/DESCRIPTION block copied from the DWARF specification.
My assumption is that anyone editing this code should be consulting the
latest version of the spec, which is the (only) source of truth. This
approach doesn't scale, create the opportunity for subtle bugs and makes
the code harder to read.
Anything LLDB specific (i.e. that's not part of the spec) is preserved.

[GlobalISel] Skip expensive dereferenceable checks at O0 (#195012)
IRTranslator::translateLoad is hot and showing up in compile-time
profiling of sqlite on aarch64-O0-g builds. Around 1/3 of the time is
spent in TargetLoweringBase::getLoadMemOperandFlags which is dominated
by isDereferenceableAndAlignedPointer inferring dereferenceable
metadata.
This metadata is for the optimizer and not necessary for correctness.
Skipping at O0 is -0.21% geomean improvement on CTMark. This brings
GISel more inline with FastISel which also doesn't infer this metadata.

[lldb][Darwin] Don't add zero-length segments to SectionLoadList (#195206)
On Darwin systems with a shared cache, all the system binaries are
combined into a single range of virtual address space, placing all the
TEXT segments together, all the DATA segments together, etc. It shrinks
the sizes of the segments from their on-disk file size to the actual
size needed for their contents, instead of observing page alignment
rules for segments.
And in one uncommon case, it is possible for a segment to not be put in
the shared cache virtual range at all.
When DynamicLoaderDarwin adds each file's segments to the Target
SectionLoadList (the table showing what VM ranges they are mapped to),
we're using the original file's segment sizes. But the in-memory segment
sizes may be different for binaries in the shared cache. And for a
segment which is eliminated entirely (zero length), we'll get warnings
as the next segment is added to the same address in the SectionLoadList.
To start with, this PR is handling the special case of these segments
that become zero length -- by not adding them to the SectionLoadList at
all.

[lldb] Implement delayed breakpoints (#192971)
This patch changes the Process class so that it delays *physically*
enabling/disabling breakpoints until the process is about to
resume/detach/be destroyed, potentially reducing the packets transmitted
by batching all breakpoints together.
Most classes only need to know whether a breakpoint is "logically"
enabled, as opposed to "physically" enabled (i.e. the remote server has
actually enabled the breakpoint). However, lower level classes like
derived Process classes, or StopInfo may actually need to know whether
the breakpoint was physically enabled. As such, this commit also adds a
"IsPhysicallyEnabled" API.

[AArch64] Extend SBC combine to handle CSET HI (#192708)
The `performSubWithBorrowCombine` previously only matched `CSET LO`
(unsigned <).
This extends it to also handle `CSET HI` (unsigned >) by swapping the
`SUBS` operands, since `a > b` is equivalent to `b < a`.
This resolves the FIXME left in the test from #165271.

[Clang][Coroutines] Don't emit fake uses for coroutine parameters (#194690)
Fixes issue: https://github.com/llvm/llvm-project/issues/192351
The combination of coroutines with -fextend-variable-liveness has
resulted in use-after-free, caused by the fact that we insert fake uses
of coroutine parameters at the end of the coroutine. While this is fine
for normal functions, in coroutines these variables are stored in the
coroutine frame, which is freed before the end of the function; this
results in us loading from the deleted frame.
This patch fixes this by no longer emitting fake uses for most coroutine
parameters. Since coroutine parameters will be saved back to the frame
when we suspend, and currently may not be optimized out, fake uses are
not needed in this case, and so by not emitting them we avoid dealing
with the complexity of updating fake uses in the CoroSplit pass. The
exception to this is 'this', which is not saved to the frame.

[LoopUnroll] Allow runtime unroll with remainder for uniform trip count in convergent loops (#192819)
When a loop contains convergent operations, runtime unrolling with a
remainder is currently blocked because the remainder prelude adds a
control-flow dependency. However, if the backedge-taken count is
uniform across all threads, all threads take the same path through the
prelude, making the remainder safe.
Add divergence analysis to check if the BTC SCEV is uniform, and if so,
allow AllowRemainder and UP.Runtime even for convergent loops. This
resolves the TODO at the former line 1375.

The current implementation lists all clauses that contain an

that is not listed, it returns nullptr.
The new implementation traverses an AST node until it finds an
OmpObjectList, and when one isn't found, returns nullptr. This is
actually simpler and is independent of any changes to the AST.

think compares that are used by it are vector compares.

[flang][OpenMP] Check conflicts between predetermined/explicit DSA (#194961)
Improve checks for loop iteration variables with predetermined DSA
appearing in DSA clauses. Show both the location of the variable in the
offending clause, and in the loop.
Make the checks a bit more accurate as well: only allow LINEAR clause on
SIMD construct with a single affected loop.

Fix crash on mixed-address-space pointers in no-AA store check.
`areNonOverlapSameBaseLoadAndStore` built `ConstantRanges` from `APInts`
sized by the load and store pointer index widths. When those widths
differ (AMDGPU's AS=0 vs AS=5), `ConstantRange::intersectWith` asserts.
Adds early return mirroring `BasicAA` path.
This can happen when `FindAvailableLoadedValue` is called without
`BatchAAResults`. The path with `BatchAAResults` already handles it.
This crash was observed in #190607, so it was reverted in #195135.

[LoopVectorize] Reland: Add metadata to distinguish vectorized loop body from scalar remainder (#194912)
Reland of #190258, reverted in #194901 due to a null-pointer dereference
when the scalar preheader is absent. Fixed by guarding the metadata
emission with a null check on `ScalarPH`. Also adds a dedicated test
(`vectorize-loop-kind-metadata.ll`) verifying the metadata is emitted
only when remarks are enabled.
---
Add two new loop metadata attributes — `llvm.loop.vectorize.body` and
`llvm.loop.vectorize.epilogue` — that the loop vectorizer sets on the
generated vector loop and epilogue loop respectively. The metadata is
only emitted when optimization remarks are enabled (`ORE->enabled()`),
so it has zero cost in normal compilation.
These enable downstream passes (LoopUnroll, WarnMissedTransforms) to
produce more precise optimization remarks. Instead of the generic "loop
not unrolled" warning on a source line that was vectorized, the unroller
can now report:
- **"vectorized loop"** for the main vector body
- **"epilogue loop"** for the scalar epilogue/remainder
- **"epilogue vectorized loop"** for an epilogue that was itself
vectorized during epilogue vectorization (carries both attributes)
A shared `getLoopVectorizeKindPrefix()` helper in
`LoopUtils.h`/`LoopUtils.cpp` reads the metadata and returns the
appropriate prefix string, used by both `LoopUnroll.cpp` and
`WarnMissedTransforms.cpp`. The metadata emission in `VPlan.cpp` uses
`Loop::addIntLoopAttribute` from the NFC PR #194676.
Two end-to-end tests exercise the full `loop-vectorize → loop-unroll`
pipeline with forced epilogue vectorization
(`-enable-epilogue-vectorization -epilogue-vectorization-force-VF=4`) to
produce all four loop categories from a single vectorizable function.
Each test also includes a plain (non-vectorized) function to cover the
baseline "loop" case. Both tests verify stderr diagnostic output and
YAML structured remarks.
**`LoopUnroll/vectorizer-loop-kind-remarks.ll`** checks for
successful-unroll remarks.
**`LoopTransformWarning/vectorizer-loop-kind-unroll-warning.ll`** checks
for failed-unroll warnings.

working on fixes for both of these.

[RISCV] Optimize scalable multiply reductions lowerings (#193528)
Now that we can correctly lower a scalable multiply reduction, lets
improve the lowering for two common cases.
1) If we have exact VLEN, just convert to the fixed vector
form and lower so that we get shuffles instead of the
slow painful loop.
2) Handle the high LMUL case by splitting down to m1 via
a reduce tree. It's only at the final stage that we need
to use the loop to handle the unknown number of elements.
For context, this is mostly for completeness. I don't plan on going any
further to improve the code quality here. There's more we can do (e.g.
exploiting minimum element count to use shuffles for the first couple
stages), but that can be future work.
Code written by Claude with heavy guidance and review by me.

[LLVM] Refactor intrinsic validation (#194061)
Refactor intrinsic validation to generate an error message as a part of
validation and using this functionality in various places. The main
parts of the change are:
1. Change `matchIntrinsicSignature` to return a bool and print an error
message when the match fails to a `raw_ostream`. The intent is that
`matchIntrinsicSignature` can be improved to generate more precise error
message instead of a simple pass/fail signal (not done in this change).
2. Absorb the validation of variadic argument into
`matchIntrinsicSignature`.
3. Rename `getIntrinsicSignature` to `isSignatureValid` to better
reflect its meaning and have it write an error message to a passed in
`raw_ostream` when it returns false.
4. Change verifier to use `isSignatureValid` to validate the intrinsic
declaration.
5. Make error messages related to intrinsics in Verifier start with
lower case, to that the same error message can be shared between
verifier and parser.
After this change, `matchIntrinsicSignature` is called only from within
`Intrinsics.cpp`, so we could make it a static function, but not doing
that yet.

In addition to code deduplication, it also helps to avoid hard-coded

allowing a pre-built LLVM distribution for Windows to be used on another

[flang][Semantics] Break recursion on illegal recursive type in I/O check (#194284)
When an illegal recursive derived type (a non-POINTER/non-ALLOCATABLE
component whose type is the enclosing type itself, prohibited by F2023
C749) is used in an I/O list, the component-walking helpers
FindUnsafeIoDirectComponent() and FindInaccessibleComponent() recursed
through it forever and blew the stack.
The fix involves tracking the derived types currently on the recursion
path in a VisitedSymbolSet to detect loops.
Fixes #192387

behavior. If/when the bug is fixed lowering will be incorrect.
SETREG is not a piggybacking target anymore. Instead piggybacking is
disabled if we have seen a SETREG since the last mode change.

```
llvm-cov export /tmp/Cov/bin/lld -instr-profile=/tmp/Cov/cov.profdata -format=lcov --sources lld/ELF/Arch/RISCV.cpp

does not finish after minutes.
Root cause: The expansion-region count propagation loop is bounded by
`VirtualFileMapping.size()`, the number of macro expansions.
In the TableGen-generated `RISCVGenDAGISel.inc` (depended on by
LLVMLTO), `NumFileMappings` is 74941 (largely due to the `TARGET_VAL`
macro). With 149887 mapping regions, the loop does not finish after more
than ten minutes.
Fix with an early break.

[SelectionDAG] Use Magic Algorithm for Splitting UDIV/UREM by Constant (#154968)
For integer types twice as large as a legal type, we have previously
generated a library call if another splitting technique was not
applicable.
With this change, we use an adaption of the Magic algorithm. This
algorithm is also used for UDIV/UREM by constants on legal types. The
implementation introduced here is a simple port of the already existing
implementation to types twice the size of a legal type. The core idea of
this algorithm is to replace (udiv x c) for a constant c with the bits
higher or equal to the s-th bit of the multiplication of x by (2^s +
o)/c
for some s and o. More details are available in Henry S. Warren, Jr.:
"Hacker's Delight", chapter 10.
An efficient handling of UDIV/UREM by constants on types twice as large
as a legal type is mostly relevant for 32-bit platforms. But some
projects may also benefit on 64-bit platforms. For example, the `fmt`
library for C++ uses 128-bit unsigned divisions by 100 and 10000, which
have not been covered by the previously existing optimizations.
Closes #137514.

[SLP] Refine loop-aware gather cost and admit sibling-loop subtrees
Factor the loop-nest walk out of getScaleToLoopIterations() into a pure
getLoopNestScale(). Reused by a new getGatherNodeEffectiveScale()
(-slp-per-lane-gather-scale, on by default) that averages per-lane
scales so LICM-hoistable gather operands no longer pay the inner loop's
trip count. Also, relax the tree-builder's loop-nest guard to admit
sibling inner loops sharing a common outer loop only when SCEV proves
equal backedge-taken counts.

[AMDGPU][SIInsertWaitcnts] Fix iota_range assertion when OtherMarks is empty in mergeAsyncMarks() (#193499)
WaitcntBrackets::mergeAsyncMarks() asserts when merging async wait-count
state at a CFG join point where one predecessor has pending async memory
operations and the other does not.
Problem:
- The existing early-exit only handles the both-empty case
- When OtherMarks is empty but AsyncMarks is not, MergeCount = min(0, N)
= 0
- seq_inclusive<unsigned>(1, 0) fires: "Assertion Begin <= End failed"
Changes:
- Add early return when MergeCount == 0 (OtherMarks is empty)
- When the other predecessor contributed no async marks, our marks are
unchanged and no stricter waits are needed
- Add regression lit test: asyncmark-merge-empty-other.mir

[AMDGPU][NFC] Update join/signal ordering in named barrier tests (#195316)
The ISA requires that you join a barrier before signaling it if you're
planning to wait on that barrier. Some IR-level tests have the join and
signal in the wrong order, confusing people.
This PR reorders join and signal.var in order to make correct usage more
obvious going forward.

simplifies usage and avoids the overhead of parsing format strings for
simple type appends.

[libc] Implement sys/personality.h (#195065)
Added the personality() syscall wrapper, which sets or queries the
process execution domain. The function signature follows the Linux man
page: int personality(unsigned long persona).
New files:
* libc/include/sys/personality.{yaml,h.def}
* libc/src/sys/personality/ (implementation + linux/ syscall)
* libc/test/src/sys/personality/ (unit tests)
Registered the entrypoint and header for x86_64, aarch64, riscv, and
arm. The implementation includes <linux/personality.h> for the
kernel-defined constants (PER_LINUX, ADDR_NO_RANDOMIZE, etc.) following
the same pattern as sys/prctl.h.

[dsymutil] Make --linker explicit in every test (#195293)
Pass `--linker classic` or `--linker parallel` on every `dsymutil`
invocation instead of relying on the implicit default. This preserves
the existing coverage in preparation for toggling the default in the
future.
Tests previously exercising only one linker now mirror the RUN block for
the other, sharing FileCheck prefixes. Not all tests are compatible, and
I've added a FIXME to make them easy to spot.

No caller passes IsConstReturn=true with IsRef=false. The existing AST
tests ( StructuredBuffers-AST.hlsl, ByteAddressBuffers-AST.hlsl,
TypedBuffers-AST.hlsl) already assert the by-value Load return type is
non-const, so behavior is verified unchanged.

[lldb][debugserver] Don't duplicate loaded binaries in jStopInfo (#195343)
RNBRemote::GetJSONThreadsInfo() has a bool mode switch: Only
exception-related information information about threads which had an
exception, or full information about all threads. The exception-related
information is what ends up in the `jstopinfo` key in the stop packet,
asciihex encoded. The full information is what is sent for the
`jThreadsInfo` packet, with full information for all threads at a public
stop.
When I added the `added-binaries` and `detailed-binaries-info` keys to
the thread description, I incorrectly put this in the exception related
block of this method. Move that in to the "full information" section of
the method, so we don't duplicate the information that is included in
the stop packet, asciihex encoded at that.

[lldb] Thread DWARFExpression::Evaluate state through an EvalContext (NFCI) (#195220)
Collect the inputs, derived pointers, and mutable evaluation state of
DWARFExpression::Evaluate into a file-local EvalContext struct passed by
reference to the static helpers.
Two incidental fixes making this not-quite NFC:
1. Evaluate_DW_OP_deref_size renamed to Evaluate_DW_OP_deref and takes
the LocationAtom, so error messages name the actual opcode.
2. ResolveLoadAddress no longer crashes on null exe_ctx (uses
eval_ctx.target, which is null-safe).
I initially prototyped a visitor-like design, centered around a
DWARFEvaluator class with one method per opcode and shared state as
members. I discarded it because moving the simple operations out of the
switch hurt readability and increased mental overhead. Its only real
benefit were the cleaner signatures, which this patch achives by using
the new EvalContext.

[libc] Fix personality buildbot failures (#195364)
Remove the `#include <sys/personality.h>` from the implementation
header. On buildbots, the generated header does not exist at compile
time, so `-idirafter/usr/include` pulls in glibc's version instead.
Glibc's header uses `__BEGIN_DECLS` and `__THROW`, which are unavailable
in the freestanding build.
The include was unnecessary. The function signature only uses basic
types.
Fixes buildbot failures introduced by #195065:

[HLSL] Leave out entryname from string table for PSV versions < 3 (#191528)
This PR adjusts how the string table is generated for PSV versions 1 and
2. Previously, the
string name would be unconditionally added to the string table, when it
should only be added in version 3.
Adds a test to verify there is no entry name in the string table for
older PSV versions.
