[MLIR][Presburger] Fix stale pivot in Smith normal form (#189789)
The pivot used to fix divisibility in Smith normal form is stale. This
will not affect correctness, but can lower efficiency since the outer
loop will be executed more times.
Thanks for @benquike of discovering this.

[dsymutil] Add support for pseudo probes (#186877)
This patch teaches dsymutil to transfer the `__PSEUDO_PROBE` segment and
`__probes` and `__probe_descs` section when creating dSYMs. Without this, both probe sections will get an invalid offset in the dsym bundle.

[DSE] Introduce `eliminateRedundantStoresViaDominatingConditions` (#181709)
While optimizing tautological assignments, if there exists a dominating
condition that implies the value being stored in a pointer, and such a
condition appears in a node that dominates the store via equality edge,
then subsequent stores may be redundant, if no write occurs in between.
This is achieved via a DFS top-down walk of the dom-tree, collecting
dominating conditions and propagating them to each subtree, popping them
upon backtracking.
This also generalizes `dominatingConditionImpliesValue` transform, which
was previously taking into account only the immediate dominator.

[Polly] Assumptions used to derive domain must not be pruned by that domain (#190436)
The code that emits the conditions for whether a statement is executed
by checking whether we are in the statement's domain may apply
assumptions (such as an integer truncation being reversible). Later code
then assumes that these assumptions are only relevent for then the
statement is executed, but actually it is used for determining whether
it is executed.
Break this circular reasoning by introducing an `IsInsideDomain` flag
that can be set when the domain has not been verified yet.
Fixes #190128
Thanks to @thapgua for the bug report

To avoid potential memory leaks, this PR defers the ModuleOp cloning
until after the verification check. If the check fails, the
moduleVariant might not be properly deallocated(original
implementation), leading to a memory leak. Therefore, this PR ensures
that the clone operation is only performed after a successful check. It
is part of https://github.com/llvm/llvm-project/pull/189353.

[lldb] Fix alias parsing with joined options (#190301)
Fixes a crash with the following alias, which I use for printing the
contents of pointer variables:
```
command alias vp v -P1
```
At some point in the recent-ish past, parsing this alias has started
crashing lldb. The problem is code that assumes the option and its value
are separate. This assumption causes an index past the end of a vector.
This fix changes `FindArgumentIndexForOption`. The function now returns
a pair of indexes, the first index is the option, the second index is
the index of the value. In the case of joined options like `-P1`, the
two indexes are the same.

of the expressions SCEV flags and the use-specific flags.
SCEVExpander has been updated to use this new helper.
In order to avoid other changes, the original names are exposed via
constexpr in SCEV. Not sure if there's a nicer way. One alternative
would be to define the enum in struct, and have SCEV inherit from it.
The patch also clarifies that the SCEVUse flags encode NUW/NSW, and
hides getInt, setInt, etc to avoid potential mis-use.

[IR] Use iteration limit in stripPointerCastsAndOffsets (#190472)
Using a SmallPtrSet is not quite free for such a frequently called
operation. However, calls on ill-formed IR are not particularly rare, so
some iteration limit is needed. Therefore, use a simple counter.
Termination statistics on a Clang Release build for N>5:
2448 N=6
1295 N=7
480 N=8
294 N=9
160 N=10
14350 (endless loop)
Therefore, bound the number of iterations by 12, which should cover most
practically relevant cases.
It is worth noting that _all_ of the endless loop cases have the
following form:
%incdec.ptr = getelementptr inbounds nuw i8, ptr %incdec.ptr, i64 <N>
I haven't investigated where exactly this comes from, though; but it
occurred frequent enough to add a special case for this.

[lldb] Inherit Host::GetEnvironment() when launching a wasm runtime (#190476)
Some WebAssembly runtimes might use environment variables such as `HOME`
or `XDG_CONFIG_HOME` to store configuration files, additionally some VMs
might allow wasm modules to read environment variables from the host.
Currently, if a runtime is launched using the WebAssembly platform it
doesn't inherit the environment. As a result wasm runtimes and modules
are unable to read from environment variables and might even fail to
launch (if the config file is required). This PR aims to resolve this
issue, I have tested this with the WARDuino runtime and my WIP gdbstub.

[clang] NFC: Add test case for #178324 and mark it as fixed (#190490)
Issue #178324 was actually fixed by #187755
We lost the "declaration does not declare anything" warning since the
regression was introduced, but that was because:
1) Since #78436 we treat __builtin_FUNCSIG in a dependent context
effectivelly as if it contained a template parameter.
2) Our decltype implementation treats eexpressions containing template
parameters as if they were completely opaque (but alas this goes against
the spec, which says in [temp.type]p4 this should be looking only at
type dependence).
3) Since the decltype is opaque, we don't know what lookup will find, so
we can't issue the warning because we don't know if we are going to end
up with a type or an expression.
Fixes #178324

[lldb] Bring more diagnostics in compliance with our coding standards (#190410)
The LLVM Coding Standards [1] specify that:
> [T]o match error message styles commonly produced by other tools,
> start the first sentence with a lowercase letter, and finish the last
> sentence without a period, if it would end in one otherwise.
Historically, that hasn't been something we've enforced in LLDB, but in
the past year or so I've started to pay more attention to this in code
reviews. This PR brings more error messages in compliance, further
increasing consistency.
I also adopted `createStringErrorV` where it improved the code as a
drive-by for lines I was already touching.

[runtimes] Skip custom linker validation for gpu/offload targets (#189933)
This fixes `Host compiler does not support '-fuse-ld=lld'` error when
cross-build libclc for gpu target. Cmake configure command is:
-DRUNTIMES_amdgcn-amd-amdhsa-llvm_LLVM_ENABLE_RUNTIMES=libclc \
-DLLVM_RUNTIME_TARGETS="amdgcn-amd-amdhsa-llvm"
libclc targets only support offload target cross-build and can't link
host executable. The configuration error is false positive for offload.
This PR adds a baseline test to first check if the target can link
executable. If it fails (typical for gpu/offload), we skip the custom
linker validation.

[InstCombine] Fix #163110: Support peeling off matching shifts from icmp operands via canEvaluateShifted (#165975)
Consider a pattern like `icmp (shl nsw X, L), (add nsw (shl nsw Y, L),
K)`. When the constant K is a multiple of 2^L, this can be simplified to
`icmp X, (add nsw Y, K >> L)`.
This patch extends canEvaluateShifted to support `Instruction::Add` and
updates its signature to accept `Instruction::BinaryOps` instead of a
boolean. This change allows the function to distinguish between LShr and
AShr requirements, ensuring that information is preserved according to
the signedness and overflow flags (nsw/nuw) of the operands.
The logic is integrated into `foldICmpCommutative` to enable peeling off
matching shifts from both sides of a comparison even when an offset is
present.

Split DWARF v2 tests to exclude 64-bit AIX targets (#189077)
64-bit AIX requires DWARF64 format, which was only introduced in DWARF
v3. DWARF v2 only supports 32-bit DWARF format, making it incompatible
with 64-bit AIX (the compiler throws a fatal error). These changes split
DWARF v2 tests into separate files that exclude 64-bit AIX targets while
still running on 32-bit AIX and other 64-bit platforms where DWARF v2 is
supported.

[clang][bytecode] Don't unref constexpr-unknown references (#190177)
If the pointer for a reference is constexpr-unknown, use the pointer
itself instead, instead of dereferencing it. Unfortunately, that means
constexpr-unknown pointers to reach a lot more places than before.

[Support][ValueTraking] Improve KnownFPClass for fadd. Handle infinity signs (#190559)
Improve KnownFPClass reasoning for fadd:
- Refine NaN handling for infinities by checking opposite-sign cases:
- `-inf` + `+inf` --> `nan`
- `+inf` + `-inf` --> `nan`
- `+inf` + `+inf` --> `+inf`
- `-inf` + `-inf` --> `-inf`
- Introduce `cannotBeOrderedLessEqZero` as pair to
`cannotBeOrderedGreaterEqZero`.

It seems the known bits handling added in

is insufficient to perform many range based optimizations. For some
reason
computeConstantRange doesn't fall back on KnownBits, and has a separate,
less used form which tries to use computeKnownBits.

Added vector intrinsics for

vshl_n_s64
vshl_n_u8
vshl_n_u16
vshl_n_u32
vshl_n_u64
these cover all the vector intrinsics for constant shift
the method followed
1) the vectors for quad words are of the form `64x2`, `32x4`, `16x8`,
`8x16` and the shift is a constant value but for shift left we need both
of them to be vectors so we take the constant shift and convert it into
a vector of respective form, for `64x2` we convert the constant to
`64x2`, I have learnt that this process is also called **splat**
2) After splat we have that the lhs and rhs are of the same size hence
the shift left can be applied
3) There is one issue though, the ops[0] is not of the right size, for
quad words it falls back to the default int8*16 in the function, so I am
converting it to the required size using bit casting, `8x16` = `64x2` so
we can bitcast and get the vector array in the right form.
Wrote the test cases for all the intrinsics listed above

When
set, the lowering uses the record's data size (excluding tail padding)
for
the memcpy length. This keeps typed semantics and promotability of
cir.copy.

and expose RecordType::computeStructDataSize() for computing data size

[mlir][ABI] Add writable, dead_on_unwind, dead_on_return, nofpclass param attrs to LLVM dialect (#188374)
The MLIR LLVM dialect is missing support for several parameter
attributes that
exist in LLVM IR: `writable`, `dead_on_unwind`, `dead_on_return`, and
`nofpclass`. This adds them to the kind-to-name mapping in
`AttrKindDetail.h`
and the corresponding name accessors in `LLVMDialect.td`.
The existing generic conversion infrastructure in `ModuleTranslation`
and
`ModuleImport` picks them up automatically — `writable` and
`dead_on_unwind`
round-trip as `UnitAttr`, while `dead_on_return` and `nofpclass`
round-trip as
`IntegerAttr`.
CIR needs these to match classic codegen's ABI output (sret gets
`writable
dead_on_unwind`, indirect args get `dead_on_return`, fast-math FP args
get
`nofpclass`).

[RISCV][P-ext] Add isel patterns for for macc*.h00/macc*.w00. (#190444)
The RV32 macc*.h00 instructions take the lower half words from rs1 and
rs2, compute the full word product by extending the inputs, and
add to rd. The RV64 macc*.w00 is similar but operates on words
and produces a double word result.
I've restricted this to case where the multiply has a single use.
We don't have a general macc that multiplies the full xlen bits
of rs1 and rs2, so I'm allowing the input to be sext_inreg/and or
have sufficient sign/zero bits according to
ComputeNumSignBits/computeKnownBits.
We should also add mul*.h00/mul.*w00 patterns, but those we should
restrict to at least one input being sext_inreg/and and prefer
regular mul when there are no sext_inreg/and.

[Inliner] Put inline history into IR as !inline_history metadata (#190092)
So that it's preserved across all inline invocations rather than just
one inliner pass run.
This prevents cases where devirtualization in the simplification
pipeline uncovers inlining opportunities that should be discarded due to
inline history, but we dropped the inline history between inliner pass
runs, causing code size to blow up, sometimes exponentially.
For compile time reasons, we want to limit this to only call sites that
have the potential to inline through SCCs, potentially with the help of
devirtualization. This means that the callee is in a non-trivial
(Ref)SCC, or the call site was previously an indirect call, which can
potentially be devirtualized to call any function.
The CGSCCUpdater::InlinedInternalEdges logic still seems to be relevant
even with this change, as monster_scc.ll blows up if I remove that code.

[MCA] Enhance debug prints of processor resources (#190132)
Previously, `computeProcResourceMasks()` would print resource masks on
debug mode from multiple call sites, creating noise in the debug output.
This patch aims to fix this and also print more info about the
resources.
It splits to 2 types of debug prints for resources:
1. No simulation - mask only
2. Simulation - mask + other info
For 2, it shares printing on a single place in `ResourceManager`
constructor, that should cover all the other simulation cases
indirectly:
1. `llvm/lib/MCA/HardwareUnits/ResourceManager` - covered
2. `llvm/lib/MCA/InstrBuilder.c` - should be covered indirectly - only
used by `llvm-mca` before simulation that constructs a `ResourceManager`
3. `llvm/tools/llvm-mca/Views/SummaryView.cpp` - after simulation that
constructs a `ResourceManager`
4. `llvm/tools/llvm-mca/Views/BottleneckAnalysis.cpp` - after simulation
that constructs a `ResourceManager`
It also adds `BufferSize` to the output, which should be useful to debug
scheduling model + MCA integration.
For 1, it inlines mask-only printing into 2 other callers:
1. `llvm/include/llvm/MCA/Stages/InstructionTables.h`
2. `llvm/tools/llvm-exegesis/lib/SchedClassResolution.cpp`
as they only use the masks there. I think this is a reasonable
duplication across distinguishably different users/tools.
Now every pair of callers, even across groups (1 and 2), effectively
print in a mutually exclusive way.
The patch adds debug tests for the 3 new callers, in the corresponding
root test directories, to drive further location of logically
target-independent tests that just require some target at the root. I
think this convention is more discoverable, and is pretty widely used in
the project.

[Hexagon] Pass -pie to linker when PIE is the toolchain default (#189723)
The Hexagon driver only checked for an explicit -pie flag when
constructing the link command, ignoring the toolchain's PIE default. For
linux-musl targets, isPIEDefault() returns true (via the Linux toolchain
base class), so the compiler generates PIC/PIE code (-pic-level 2
-pic-is-pie) but the linker never received -pie.
This mismatch caused LTO failures: without -pie the linker sets
Reloc::Static for the LTO backend, which generates GP-relative
(small-data) references that lld cannot resolve.
Use hasFlag() to respect the toolchain default, and guard the -pie
emission against -shared and -r (relocatable) modes.

When a VFS overlay YAML file contains malformed content such as tabs,
the YAML parser can produce KeyValueNode entries where `getKey` returns
nullptr. The VFS overlay parser then passes the nullptr to
`parseScalarString`, which then calls dyn_cast.
Switch to `dyn_cast_if_present` for the above callsites and a few more.

[lldb][NativePDB] Handle `S_DEFRANGE_REGISTER_REL_INDIR` (#190336)
Since #189401, LLVM and Clang generate `S_DEFRANGE_REGISTER_REL_INDIR`
for indirect locations. This adds support in LLDB.
The offset added after dereferencing is signed here - unlike in
`S_REGREL32_INDIR` (at least that's the assumption). So I updated
`MakeRegisterBasedIndirectLocationExpressionInternal` to handle the
signedness. This is the reason the MSVC test was changed here.
I didn't find a test case where LLVM emits the record with the `VFRAME`
register. Other than that, the clang test is similar to the MSVC one
except that the locations are slightly different.

[CodeGen] Move rollback capabilities outside of the rematerializer (#184341)
The rematerializer implements support for rolling back
rematerializations by modifying MIs that should normally be deleted in
an attempt to make them "transparent" to other analyses. This involves:
1. setting their opcode to DBG_VALUE and
2. setting their read register operands to the sentinel register.
This approach has several drawbacks.
1. It forces the rematerializer to support tracking these "dead MIs"
(even if support is optional, these data-structures have to exist).
2. It is not actually clear whether this mechanism will interact well
with all other analyses. This is an issue since the intent of the
rematerializer is to be usable in as many contexts as possible.
3. In practice, it has shown itself to be relatively error-prone.
This commit removes rollback support from the rematerializer and moves
those capabilities to a rematerializer listener than can be instantiated
on-demand and implements the same functionality on top of standard
rematerializer operations. The rematerializer now actually deletes MIs
that are no longer useful after rematerializations, and has support for
re-creating them on-demand without requiring additional tracking on its
part.

Add a fuzzer that creates an on-disk CAS database, stores objects, then
corrupts the on-disk data files using fuzzer-provided bytes and calls
validate(). The goal is that validate() should either succeed or return
an error, never crash.
The fuzzer supports 6 corruption modes: byte-level mutations, file
truncation, appending garbage, zeroing ranges, standalone file
corruption, and combined mutations with continued CAS operations.

[CAS] Harden validate() against on-disk corruption (#190634)
Fixes found by fuzzer:
OnDiskTrieRawHashMap:
- Bounds-check data slot offsets in TrieVerifier::visitSlot() before
calling getRecord(), preventing asData() assertion on out-of-bounds
trie entries.
- Validate subtrie headers (NumBits, bounds) before constructing
SubtrieHandle, preventing SEGV in getSlots() from corrupt NumBits.
- Validate arena bump pointer alignment, catching misaligned BumpPtr
that would crash store() with an alignment assertion.
- Fix comma operator bug in getOrCreateRoot() where the
compare_exchange_strong result was discarded, causing asSubtrie()
assertion when RootTrieOffset was corrupted to zero.
OnDiskGraphDB:
- Reject invalid (zero) ref offsets in validate callback, preventing
asData() assertion when corrupt data pool refs are resolved via
recoverFromFileOffset().
- Validate DataRecordHandle layout flags before calling getTotalSize(),
preventing llvm_unreachable on corrupt NumRefsFlags/DataSizeFlags.
- Validate data pool bump pointer alignment, catching misaligned
BumpPtr that would crash store() in DataRecordHandle::constructImpl().
- Check data record refs offset alignment before calling getRefs(),
preventing PointerUnion assertion from misaligned refs pointer.
MappedFileRegionArena:
- Convert assertions in initializeHeader() to errors so corrupted
arena headers return an error on CAS open instead of crashing.

[LoopFusion] Fix out-of-date LoopInfo being used during fusion (#189452)
This is fix for
[187902](https://github.com/llvm/llvm-project/issues/187902), where
`LoopInfo` is not in a valid state at the beginning of `ScalarEvolution::createSCEVIter`.
The reason for the bug is that, `mergeLatch()` is called at a place
where control flow and dominator trees have been updated but `LoopInfo`
has not completed the update yet. `mergeLatch()` calls into
`ScalarEvolution` that uses `LoopInfo`, where out-of-date `LoopInfo` would
result in crash or unpredictable results.
This patch moves `mergeLatch()` to the place where `LoopInfo` has
completed its update and hence is in a valid state.

[llvm-cov] Guard against empty CountedRegions in findMainViewFileID (#189270)
When processing coverage generated from branch coverage mode, some
functions can reach findMainViewFileID with an empty CountedRegions
list. In that case the current logic still proceeds to infer the main
view file, even though there is no regular counted region available to
do so.
Return std::nullopt early when CountedRegions is empty.
This was observed when reproducing issue #189169 with:
cargo llvm-cov --lib --branch
The issue appears related to branch-only coverage information being
recorded separately in CountedBranchRegions, while
findMainViewFileID currently only consults CountedRegions.
This patch is a defensive fix for the empty-region case; further
investigation may still be needed to determine whether branch regions
should participate in main view file selection.

[MLIR][ExecutionEngine] Tolerate CUDA_ERROR_DEINITIALIZED in mgpuModuleUnload (#190563)
`mgpuModuleUnload` may be called from a global destructor (registered by
`SelectObjectAttr`'s `appendToGlobalDtors`) after the CUDA primary
context has already been destroyed during program shutdown. In this
case, `cuModuleUnload` returns `CUDA_ERROR_DEINITIALIZED`, which is
benign since the module's resources are already freed with the context.
## Reproduction
Any program that uses `gpu.launch_func` and is AOT-compiled (via
`mlir-translate --mlir-to-llvmir | llc | cc -lmlir_cuda_runtime`) will
print `'cuModuleUnload(module)' failed with '<unknown>'` on exit. This
is because `SelectObjectAttr` registers the module unload as a global
destructor, which runs after the CUDA primary context is released.
This script reproduces the error message from `mgpuModuleUnload` on my
system:
```
#!/bin/bash
set -e
LLVM_BUILD=${LLVM_BUILD:-$HOME/dev/git/llvm-project-22/build}
cat > /tmp/repro.mlir << 'MLIR'

threads(%tx, %ty, %tz) in (%bsx = %c1, %bsy = %c1, %bsz = %c1) {
gpu.terminator
}
return

```
## Context
This matches how other projects handle the same shutdown ordering issue:
- Clang CUDA (D48613) switched module cleanup from
`__attribute__((destructor))` to `atexit()`
- GCC libgomp checks context validity before `cuModuleUnload`
- Apache TVM silently ignores `CUDA_ERROR_DEINITIALIZED` on module
unload

Also, replase `if (!got_op)` check with an `else`. The check is
equivalent to
`if (min_op_byte_size != max_op_byte_size)`, and the `if` above checks
for the opposite condition.

[BOLT] Allow empty buildid in pre-aggregated profile addresses (#190675)
Allow `parseString()` to return an empty `StringRef` when the delimiter
appears at position 0. This enables parsing pre-aggregated profile
addresses with an omitted buildid but preserved colon (`:addr` format),
where the empty buildid corresponds to the main binary.
Previously, `parseString()` rejected zero-length fields by treating
`StringEnd == 0` the same as `StringRef::npos` (delimiter not found).
These are distinct situations: `npos` means no delimiter exists, while
`0` means the field before the delimiter is empty. The fix removes the
`StringEnd == 0` sub-condition so only the missing-delimiter case
errors.
The existing test for buildid-prefixed addresses is extended to also
verify that `:addr` input produces identical output to the plain-address
and non-empty-buildid variants.
Test Plan:
Added empty-buildid input file and extended
`pre-aggregated-perf-buildid.test` to run perf2bolt with `:addr` format
and diff the fdata output against the existing buildid-prefixed result.

[lldb][python] Add polymorphic `__getitem__` to `SBModuleSpecList` for Pythonic indexing (#189125)
### Summary
`SBModuleSpecList` already supports `len()` and iteration via `__len__`
and `__iter__`, but is not subscriptable — `specs[0]` raises
`TypeError`.
This adds a `__getitem__` method that supports integer indexing (with
negative index support) and string lookup using `endswith()` matching,
which works for both Unix and Windows paths.
### Supported key types
| Key type | Example | Behavior |
|---|---|---|
| `int` | `specs[0]`, `specs[-1]` | Direct index with negative index
support |
| `str` | `specs['a.out']`, `specs['/usr/lib/liba.dylib']` | Lookup by
basename or partial/full path via `endswith()`. Returns first match or
`None` |
### Error handling
- **`IndexError`** for out-of-bounds integer indices
- **`TypeError`** for unsupported key types (e.g., `float`)
- **`None`** for string lookups with no match
### Before
```python
>>> specs = lldb.SBModuleSpecList.GetModuleSpecifications('/bin/ls')
>>> specs[0]
Traceback (most recent call last):
File "<console>", line 1, in <module>
TypeError: 'SBModuleSpecList' object is not subscriptable
```
### After
```python
>>> import lldb, re
>>> specs = lldb.SBModuleSpecList.GetModuleSpecifications('/bin/ls')
>>> specs[0]
file = '/bin/ls', arch = x86_64-*-linux, uuid = 3CCC0D8A-..., object size = 140928
>>> specs[-1]
file = '/bin/ls', arch = x86_64-*-linux, uuid = 3CCC0D8A-..., object size = 140928
>>> specs['ls']
file = '/bin/ls', arch = x86_64-*-linux, uuid = 3CCC0D8A-..., object size = 140928
>>> specs[999]
IndexError: list index out of range
>>> specs[1.5]
TypeError: unsupported index type: <class 'float'>
```
### Test plan
Added test_module_spec_list_indexing to TestSBModule.py covering:
- Positive and negative integer indexing
- Out-of-bounds raises IndexError
- Unsupported key type raises TypeError
- String lookup by basename and full path (endswith() matching)
- Missing key returns None

[SampleProfileMatcher] Fix backward matching of non-anchor locations (#190118)
The backward matching loop in `matchNonCallsiteLocs` was ineffective
because `InsertMatching` used `std::unordered_map::insert()` which does
not overwrite existing entries. Since forward matching already inserted
entries for all non-anchor locations, the backward matching for the
second half was silently ignored.
The backward matching can update forward mappings in
`IRToProfileLocationMap` in 2 ways:
- The IR location maps a new different profile location. Change
`insert()` to `insert_or_assign()` so that entry overwrite can happen.
- The IR location maps the same profile location. Add `erase()` to
remove such mapping.

[lldb] Change most tests to build with system libc++ on Darwin (#190034)
Today, on Darwin platforms, almost every test binary in our test suite
loads two copies of libc++, libc++abi, and libunwind. This is because
each of the test binaries explicitly link against a just-built libc++
(which is explicitly required on Darwin right now) but we don't take the
correct steps to replace the system libc++. Doing so is unnecessary and
potentially error-prone, so most tests should link against the system
libc++ where possible.
Background:
The lldb test suite has a collection of tests that rely on libc++
explicitly. The two biggest categories are data formatter tests (which
make sure that we can correctly display values for std types) and
import-std-module tests (which test that we can import the libc++ std
module). To make sure these tests are run, we require a just-built
libc++ to be used.
All of the test binaries link against the just-built libc++, so it gets
loaded. However, when any system library tries to load libc++, it
attempts to load the system one. dyld checks loaded libraries against
the request to load a new one using the full path, meaning anyone
linking against `/usr/lib/libc++.1.dylib` will get it no matter what
other libc++ dylib is already loaded.
The proper way to handle this is using `DYLD_LIBRARY_PATH`, which
switches dyld to checking the leaf name of a dylib instead of the full
path. In theory this works, but we run into an issue where the system
libc++ has additional symbols and many system libraries fail to load.
Louis Dionne added stubs in libc++abi for these missing symbols, meaning
it would be possible to make this scenario work. This may be useful for
the existing libc++ tests.

[MLIR][test] Re-disable FileCheck on async.mlir integration test (#190702)
#190563 re-enabled FileCheck on `Integration/GPU/CUDA/async.mlir`, but
the buildbot has shown intermittent wrong-output failures
([example](https://lab.llvm.org/buildbot/#/builders/116/builds/27026)):
the test produces `[42, 42]` instead of the expected `[84, 84]`.
This wrong-output flakiness is distinct from the cleanup-time
`cuModuleUnload` errors that #190563 actually fixes — it's the
underlying issue tracked by #170833. The merged commit message for
#190563 incorrectly says `Fixes #170833`; that issue should be reopened,
since the cleanup-error fix doesn't address the wrong-output behavior.
This PR puts the test back in its previously-disabled state. The runtime
cleanup fix in #190563 is unaffected.

This fixes a rematerializer issue wherein re-creating the interval of a

which defining entirely dead sub-registers, could cause a crash when
changing the order of sub-definitions (for example during scheduling)
because the re-created interval could end up with multiple connected
components, which is illegal. The solution is to split separate
components of the interval in such cases. The added unit test crashes
without that added behavior.

[Inliner] Put inline history into IR as !inline_history metadata (#190700)
(Reland of #190092 with verifier change to look through GlobalAliases)
So that it's preserved across all inline invocations rather than just
one inliner pass run.
This prevents cases where devirtualization in the simplification
pipeline uncovers inlining opportunities that should be discarded due to
inline history, but we dropped the inline history between inliner pass
runs, causing code size to blow up, sometimes exponentially.
For compile time reasons, we want to limit this to only call sites that
have the potential to inline through SCCs, potentially with the help of
devirtualization. This means that the callee is in a non-trivial
(Ref)SCC, or the call site was previously an indirect call, which can
potentially be devirtualized to call any function.
The CGSCCUpdater::InlinedInternalEdges logic still seems to be relevant
even with this change, as monster_scc.ll blows up if I remove that code.

The VPatBinaryV_VI_VROL multiclass was using InvRot64Imm for all SEW

produced unnecessarily large immediates for narrower element types

Use the appropriate InvRot{SEW}Imm transform to match what the SDNode
patterns already do.

Log Message:
-----------
Move {load,store}(llvm.protected.field.ptr) lowering to InstCombine.
The previous position of llvm.protected.field.ptr lowering for loads
and stores was problematic as it not only inhibited optimizations such
as DSE (as stores to a llvm.protected.field.ptr were not considered to
must-alias stores to the non-protected.field pointer) but also required
changes to other optimization passes to avoid transformations that would
reduce PFP coverage.
Address this by moving the load/store part of the lowering to
InstCombine, where it will run earlier than the PFP-breaking and
AA-relying transformations. The deactivation symbol, null comparison
and EmuPAC parts of the lowering remain in PreISelLowering.
Now that the transformation inhibitions are no longer needed, remove them
(i.e. partially revert #151649, and revert #182976).
This change resulted in a 2.4% reduction in Fleetbench .text size and
the following improvements to PFP performance overhead for BM_PROTO_Arena
on various microarchitectures:

[clang-tidy] Fix performance-trivially-destructible with C++20 modules (#178471)
When a class definition is seen through both a header include and a
C++20 module import, destructors may appear multiple times in the AST's
redeclaration chain. The original matcher used `isFirstDecl()` which
fails in this scenario because the same declaration can appear as both
first and non-first depending on the view.
Replace `unless(isFirstDecl())` with `isOutOfLine()` which correctly
identifies out-of-line definitions by checking whether the lexical
context differs from the semantic context.
Also update clang-tools-extra's lit.cfg.py to call `use_clang()` instead
of `clang_setup()` to make the `%clang` substitution available for
tests.
Fixes #178102

[CodeGenPrepare] Use Instruction::comesBefore instead of manual ordering (#190485)
After #172329, we noticed that some sources compiled with MSan take
1000x longer to compile. This is caused by quadratic complexity in
tryToSinkFreeOperands, which can be called on a significant number
of instructions within huge basic blocks.
This inefficiency was introduced in 9cfa9b4, which manually iterates
and creates a DenseMap of entire basic blocks for each interesting
instruction.
This patch avoids the manual ordering by using
Instruction::comesBefore(), which provides the exact same
ordering much more efficiently.

[lldb][AIX] Extract CPU type and set up process architecture accordingly (#189910)
This PR is in reference to porting LLDB on AIX. Ref discusssions: [llvm
discourse](https://discourse.llvm.org/t/port-lldb-to-ibm-aix/80640) and
[#101657](https://github.com/llvm/llvm-project/issues/101657).
Complete changes together in this draft:
- [Extending LLDB to work on AIX
#102601](https://github.com/llvm/llvm-project/pull/102601)
Description:
The process architecture was previously initialized using a hardcoded
TCPU_PPC64 CPU type.
The logic has been updated to determine the CPU type dynamically by
inspecting the magic bytes and the XCOFF header. Based on this
information, the appropriate CPU type (TCPU_PPC or TCPU_PPC64) is
selected and used when constructing and setting the ArchSpec.
This change ensures that the process architecture correctly reflects the
underlying binary format.

[AMDGPU][SILowerSGPRSpills] Correct insertion of IMPLICIT_DEF in cycles (#186348)
si-lower-sgpr spills was observed inserting IMPLICIT_DEF for lane VGPR
restores in the cycle header. The virtual VGPR is therefore not live-in
to the header and wwm regallocfast does not insert a restore. This
results in the vgpr being clobbered after each backedge.
Correct this by inserting the IMPLICIT_DEF in a block that dominates
all entries.

[clang] Fix crash on invalid out-of-line enum definition with template parameters (#188246)
clang crashes when an invalid out-of-line enum definition is provided
with template parameters. In these cases, clang produces a dependent
type within a non-dependent context, violating internal invariants.
The fix is to fallback the underlying type of the enum to `int` during
error recovery in `Sema::ActOnTag` when `Invalid` is true, making it
safe for downstream processing while still preserving the invalid
declaration in the AST.
Fixes #187909

Close https://github.com/llvm/llvm-project/issues/190333
For the test case, the root cause of the problem is, the compiler
thought the declaration of `operator &&` in consumer.cpp may change the
meaning of '&&' in the requrie clause of `F::operator()`. But it doesn't
make sense. Here we skip profiling the callee to solve the problem. Note
that we've already record the kind of the operator. So '&&' and '||'
won't be confused.

[Inline] Allow inlining with null_pointer_is_valid mismatch (#190510)
If the callee has null_pointer_is_valid but the caller does not, we
should still inline and add null_pointer_is_valid to the caller (which
is handled by an already existing inline adjustment rule).
This does mean that optimizations in the caller may be reduced by
unnecessarily preserving null checks, but that's still better than not
inlining at all. In particular, this check causes issues with LTO in the
Linux kernel, as the C portions are compiled with null_pointer_is_valid,
but the Rust portions are not.
The test is modified to show that the previous alwaysinline behavior now
always holds.

do.
Therefore, I think that this test now technically could be done with

[LLD] [COFF] Fix crashes for conflicting exports with -export-all-symbols (#190492)
Commit adcdc9cc3740adba3577b328fa3ba492cbccd3a5 (since LLD 17) added a
warning message if there are conflicting attempts to export a specific
symbol.
That commit missed one source of exports, from the LLD specific
-export-all-symbols flag (which only has an effect in mingw mode).
To trigger this case, one needs to have an export set by a def file,
combined with the -export-all-symbols flag (which attempts to export all
global symbols, despite explicit exports through embedded directives or
a def file).
To trigger the warning (and the previous crash), one would have to have
some difference between the export produced by -export-all-symbols and
the one from the def file. That difference could be e.g. that the def
file contained an explicit ordinal, or that the def file lacked a DATA
marking for a symbol that the automatic export of all symbols decides to

[flang] Fix stack-arrays pass moving alloca across stackrestore scope (#184727)
When a operand is shared between two fir.allocmem ops in different
stacksave/stackrestore scopes, findAllocaInsertionPoint() placed both
allocas at the operand definition site inside the first scope. The first
stackrestore then reclaimed both, leaving the second call with a
dangling pointer.
Add a check for intervening stackrestore ops between the last operand
and the allocmem. If one is found, fall back to the allocmem's own
location, matching the existing bail-out for cross-block operands.

[CHERI] Refine LoopIdiomRecognize handling of stable representation non-integral pointers. (#189402)
This makes two changes:
- memset can be formed from stores of null pointers, even if they are
non-integral. Null pointers are already assumed to be equivalent to the
all-zeros bit pattern, and it's not the goal of non-integral pointer
support to change that assumption.
- memcpy can be formed from copies of non-integral pointers. We assume
if the environment provides a memcpy implementation for a non-integral
pointer address space, then that memcpy is non-integral pointer aware.
These changes are not applied to pointers with unstable representation.

Generally f16 operations are promoted to f32. For bitwise-equivalent

[AArch64][GlobalISel] Add patterns for scalar sqdmlal/sqdmlsl (#187246)
SQMLAL's instruction selection patterns don't work for GlobalISel when
the intrinsic has scalar operands. This is because the intrinsic has a
slightly different name (int_aarch64_neon_sqdmulls_scalar). As a result,
this leads to sub-optimal code generation.
This patch allows sqdmulls_scalar to lower, and adds GlobalISel versions
of the TableGen patterns to provide this optimisation.
The pattern added performs this mapping:
`SQADD(a, SQDMULL(b,c)) -> SQDMLAL(a, b, c) [And equivalent for
subtraction]`

[CodeGen] Fix incorrect rematerialization order in rematerializer (#189485)
When rematerializing DAGs of registers wherein multiple paths exist
between some regsters of the DAG, it is possible that the
rematerialization determines an incorrect rematerialization order that
does not ensure that a register's dependencies are rematerialized before
itself; an invariant that is otherwise required.
This fixes that using a simpler recursive logic to determine a correct
rematerialization order that honors this invariant. A minimal unit test
is added that fails on the current implementation.

[VPlan] Optimize FindLast of (binop %IV, live-in) by sinking. (#183911)
When we are finding the last occurrence of a value of an expression that
depends on an induction, we can vectorize this by just selecting the IV
and sinking the expression in the middle block
This follows one of @ayalz's suggestions during earlier discussions for
adding support for CAS/FindLast patterns.
This patch starts with the simplest case, where the selected value is a
simple binary expression of a wide IV and a loop-invariant operand.
This should always be profitable, as the current restriction to binary
operators ensures that the width of the wide IV matches the original
reduction width, we won't introduce any new, wider reduction phi
recipes, and remove the boolean reduction + the horizontal reduction in
the loop.

FusedLoc::get(context, locs) may return UnknownLoc when locs is empty

cast<FusedLoc>() on this result, which crashes with an assertion

Fix by giving the FusedLoc DialectAttribute its own cBuilder that passes
Attribute() explicitly, causing getChecked<FusedLoc> to call the
two-parameter storage constructor directly and always produce a
FusedLoc.

Adds a ManagedCodeCallsGroup TaskGroup to Session, and updates the
shutdown sequence to wait until all calls into managed code have
completed before proceeding to shut down the Session's Services and the
Session itself.
To support safe calls into managed code two new helper template methods
are added:
callManagedCodeSync attempts to acquire a TaskGroup::Token for the
ManagedCodeCallsGroup before calling the given function and returning
its result.
callManagedCodeAsync attempts to acquire a TaskGroup::Token for the
ManagedCodeCallsGroup before calling the given async function. The
wrapped Return call for the async function will carry the acquired
Token, ensuring that shutdown waits for the async Return call to be
destroyed (whether or not it's actually called).

[NFC][analyzer] Spread use of 'Expr*' instead of 'Stmt*' (#188319)
When I was browsing the codebase, I was surprised to see that the first
parameter of `ProgramStateRef::BindExpr` was `const Stmt*` instead of
`const Expr*`. As I surveyed calls to `BindExpr`, I realized that
fortunately no code passes non-expression statements to `BindExpr`
(anymore... it seems that earlier we had such hacks) so in this commit
I'm able to change the type of the first parameter to `const Expr*`.
There was a call to `BindExpr` where the first argument was the value of
the data member `StackFrameContext::CallSite`, so I also changed the
type of that member from `const Stmt*` to `const Expr*` because it was
another statement pointer that always pointed to expressions (or null).
This commit prepares the ground for using `Expr*` instead of `Stmt*` in
`EnvironmentEntry`, which is currently a `pair<const Stmt *, const
StackFrameContext *>` and will be updated in follow-up commits.
This commit also includes minor unrelated simplifications and
corrections.

[libc] Make rpc_server.h independent from libc internals (#190423)
Summary:
It was very convenient to have the RPC server use the internal libc
printing utilities, but it caused a lot of problems. The LLVM libc
internals were never meant to be included arbitrarily and we completely
bypassed this restriction. Furthermore it prevented us from installing
and using these libraries in other contexts. There was a whole host of
hacks around this, leading to endless PPC problems, compiler errors,
etc.
This PR re-uses the old minified format parser I used to use for the GPU
case. We simply parse the formats to get the size, then copy the
strings. The actual printing instead is done by locking the output file
and repeatedly building up the string using the host's `printf`. Slight
test modifications because we no longer can depend on the specific user
printf specification, it may not handle null or binary values for
example.

Summary:
This PR enabled the ubsan-minimal target for the GPU. This should enable
the trivial checks on the GPU-side. I had to make some changes to the
common sanitizer requirements, but I think this is reasonable
considering the common_sanitizer requires a fully hosted environment and
all we needed were the headers.

[CIR][AArch64] Lower NEON vbsl builtins (#188449)
Part of : https://github.com/llvm/llvm-project/issues/185382
Add CIR lowering for the AArch64 NEON bitwise-select builtins.
Lower the NEON bitwise-select builtins to CIR bitwise operations
implementing the ACLE bitwise-select semantics, including the
floating-point forms.Also add CIR support for `mfloat8` NEON vector
types so `vbsl_mf8` and `vbslq_mf8` lower successfully instead of
hitting the existing NYI in type conversion.
Move and extend the corresponding FileCheck coverage in
`clang/test/CodeGen/AArch64/neon/intrinsics.c`.

[AArch64] Optimize vector multiplications by certain constants for v2i64 (#183827)
## Summary
This patch optimizes v2i64 multiplications by constants that can be
decomposed into a single shift and an addition/subtraction (i.e.,
constants of the form $2^n \pm 1$).
Unlike 32-bit or 16-bit vectors, AArch64 Advanced SIMD (NEON) lacks a
native v2i64 multiply instruction.
Currently, the compiler scalarizes these operations, By lowering these
specific cases to shl + add/sub, we keep the entire operation within the
SIMD unit, significantly reducing instruction count and execution
latency.
## Technical Details
- Target: AArch64 (With Neon Enabled)
- Transformation: Replaces (mul x, splat(2^n + 1)) with (add (shl x, n),
x) and (mul x, splat(2^n - 1)) with (sub (shl x, n), x).
- Placement: Integrated into performMulCombine in
AArch64ISelLowering.cpp as a targeted gate for v2i64 vector types only
(for now).

[flang][OpenMP] Fix subtle bug in GetAffectedNestDepthWithReason (#190645)
For constructs that allow COLLAPSE or ORDERED clauses, the function
would return an empty value for the affected depth if none of these
clauses were actually present. What should happen is that the return
value should be 1 without a specific reason.
This bug was not detectable with any source program, since the empty
value caused depth checks to be skipped. Detecting the problem would
require a loop nest with a lower depth than needed that the bug would
cause not to be diagnosed. Since the correct value was 1, such a loop
would need to have a depth of 0 and such a nest cannot be constructed.

[CIR] Implement aggregate-expr-init with a const-expr lowering (#190631)
An aggregate initialized by a ConstantExpr happens when you have a

There is a bit of a difference in decisions between classic-codegen and
cir lowering, where classic-codegen will do init-via-GEP, whereas CIR
does either a struct-store, or a memcpy, otherwise these seem identical.
There IS a branch (if emitting a constant-expr fails) that appears dead
to the best of my knowledge, but since classic-codegen does it, I left
the version there. It is at most a pessimisation of the constant-emit
(just emitting the expression), so it shouldn't cause problems.

[flang][OpenMP] Introduce `semantics::omp::LoopControl` (#190647)
This structure will contain the symbol for the iteration variable, the
lower and upper bounds, and the increment if present in the form of
evaluate::Expr. A source construct (such as DO CONCURRENT) may have
several iteration variables, each with its own bounds and increment,
represented by a list of LoopControl structures.
For loop-transformation constructs that produce additional loops the
current code returns an empty list of LoopControls, but it may be
extended in the future to represent the yet-nonexistent loops for more
accurate semantic analysis.
The code introduced in this PR is not executed yet, but will be used in
an upcoming PR.

[CIR] Implement constructor 'try-body' lowering (#190613)
C++ supports the ability to have the 'body' of a constructor be a 'try'
block. The effect of this is that base construction and initializers are
also within the same try/catch chain. This patch implements this
lowering.
Classic codegen does this by just emitting the 'begin' and 'end' try as
their own functions, then can emit the body separately between calls.
However, CIR doesn't really afford us that ability, so this patch
extracts a function that takes a callback object that is used to emit
the function body. This allows us to do a simple 'emitStmt' in the
normal cases, plus a `emitCtorPrologue` followed by `emitStmt` in the
try-body case.

[lldb] Make argument to ConstString::AsCString explicit (#190183)
This patch makes the default parameter to ConstString::AsCString
explicit. Currently it defaults to `nullptr`. However, there a bunch of
callsites that do `printf("%s", foo.AsCString())`, which is UB (I have
at least 1 crash on me where this was the root cause).
Alternatively we could change the default to `""` instead of `nullptr`,
but code that did `if (foo.AsCString())` would then change meaning.
Command I ran to generate this patch:
```
rg "\.AsCString\(\)" lldb -l | xargs sed -i '' 's/\.AsCString()/.AsCString(nullptr)/g'
```
There's also a commonly used `Status::AsCString` with a default
parameter. So I added a temporary:
```
const char *AsCString(std::nullptr_t) const = delete;
```
overload to `Status`, and fixed all the compile errors.
In a follow-up PR I intend to change the callsites that do `printf("%s",
foo.AsCString(nullptr)` to pass `""` as the fallback parameter. Another
dangrous pattern is `std::string(error.AsCString(nullptr))`

[lldb] Add setting to specify (by name) which module's scripting resources can be auto-loaded (#188722)
* Depends on: https://github.com/llvm/llvm-project/pull/189696
This is part of [this
RFC](https://discourse.llvm.org/t/rfc-lldb-moving-libc-data-formatters-out-of-lldb/89591)
which is about turning the libc++ data-formatters into auto-loadable
Python scripts.
Eventually we want the Python data-formatters for `libc++` to be
automatically loaded without requiring user opt-in (since that's how the
builtin formatters have always worked and, in my opinion, we can't
transition to an opt-in model if users have always had the
data-formatters available). To do so we need a way to distinguish which
modules we can *always* auto-load from safe-paths, and which require
`target.load-script-from-symbol-file` to be set to `true`.
This patch adds a setting (`target.auto-load-modules`) that is a
dictionary from module-name to the `LoadScriptFromSymFile` enum,
indicating how the scripts for that module are to be loaded.
Making this a setting also means a user can disable any auto-loading by
clearing it. By default the setting is currently empty. Eventually we'll
want it to contain `libc++.1=true` (and possibly other names which the
`libc++` dylib can commonly have).
**Considerations**:
* I thought about adding an `IsAutoLoadable` API to `FileSpec` and set
it for those that can be auto-loaded. Then we wouldn't have to return
two lists from `LocateExecutableScriptingResources`. I just felt like
`FileSpec` was too high-level of a structure to hold such information so
I opted for the `llvm::SmallDenseMap<FileSpec, LoadScriptFromSymFile>`.
If people favour one approach over the other, I'm happy to reconsider
**AI Usage**:
* Used Claude to generate the unit-test cases and shell tests. Reviewed
and cleaned them up myself.

[ConstantFolding] Fix bitcasting vectors with non-integer ratios (#179640)
For both downcast and upcast this patch introduces support for
bitcasting vectors with non-integer ratios [1, 2]. Also this patch
increases the coherence between casts [3].
1. Fixes a crash on downcast where the ratio is not an integer (e.g., <3
x i32> to <4 x i24>). Previously this led to leading to an incorrect
number of result elements and subsequent crashes in RAUW.
Fixes #179626
2. Fixes a miscompilation on upcast where ratio is not an integer (e.g.,
<4 x i24> to <3 x i32>). Previously this led to wrong result.
Fixes #181195
3. Fix incoherent value emitting between down/up cast
a. When upcasting, emit Poison and Undef not only if the source vector
consists of only one of these values. (e.g., `bitcast <4 x i32> <i32
undef, i32 undef, i32 1, i32 undef> to <2 x i64>` returns `<2 x i64>
<i64 undef, i64 1>`
b. When downcasting, when SrcElt is Poison, handle it as Poison and not
Undef. (e.g., `bitcast <1 x i32> <i32 poison> to <2 x i16>` returns `<2
x i16> poison`

[WebAssembly] Fix operand order in performBitcastCombine (#190361)
Fix operand order in performBitcastCombine for wide <N x i1> -> iN
bitmask reconstruction.
In performBitcastCombine, when reconstructing i32/i64 bitmask from
multiple v16i1 SetCC results (for N=32 and N=64 cases), the code
incorrectly built SHL nodes with reversed operands:
SHL(16, ReturningInteger) // wrong
SelectionDAG::getNode(ISD::SHL, ...) expects operand 0 to be the value
to shift and operand 1 to be the shift amount.
This produced incorrect DAGs like shl Constant<16>, xxx, leading to
wrong codegen for vector bitmask patterns.
Fixed by swapping the operands:
SHL(ReturningInteger, 16)

[llvm-mca][RISC-V] Remove duplicated use of SP from `c.addi4spn` (#189980)
`c.addi4spn` instruction implicitly uses the X2 (SP) register, but in
addition to being present in the Uses list, it is also modeled as an
explicit operand with the SP register class. This duplication causes
missed bypasses in llvm-mca when the instruction needs to read the SP
value written by a previous instruction.
For example, on a `sifive-u74` CPU, the following timeline excerpt
shows that the `c.addi4spn` is issues 2 cycles later than expected by
the GPR bypass:
```
Timeline view:
Index 012345678
[0,0] DeeE . . mv sp, a0
[0,1] . DeeE . addi a1, sp, 12
```
This patch removes SP from the Uses list, relying solely on the
explicit SP operand (as in `c.addi16sp`), which restores the expected
bypass behavior.
A test is added that checks the same scenario for `c.addi16sp` as well,
since a similar issue may also occur there.

[flang] Disambiguate derived component accesses in AliasAnalysis. (#189516)
This change introduces an AccessPath representation inside the
AliasAnalysis
Source object that tracks the sequence of named component accesses
and pointer/allocatable dereferences from the root variable to the
queried
memory location. The access path is built during the backward walk
in getSource and enables more precise alias analysis for Fortran derived
types.
Previously, accesses to different components of the same derived-type
variable (such as x%a and x%b) were reported as MayAlias
because the analysis could not distinguish them once they traced back
to the same origin. With the access path, the analysis can now identify
when two accesses diverge at a named component step
and return NoAlias for disjoint subobjects.
This patch does not get rid of `followingData` and `isData` completely.

[mlir][OpenMP] Fix taskloop outlined step handling (#190198)
The outlined taskloop preheader still used the original function's
casted step value when computing the canonical loop trip count. When
lb/ub/step were defined outside the taskloop body, the outlined function
ended up referring to an instruction from another function, which
crashed LLVM IR verification and finalization.
Reload the task step from the outlined task shareds, alongside lb and
ub, and use that value for the trip-count division. Update the MLIR
taskloop checks and add a regression for outer-scope variable bounds.
Fortran reproducer:
```
subroutine test(lb, ub, step)
integer :: i, lb, ub, step
!$omp taskloop
do i=lb,ub,step
call do_something(i)
enddo
!$omp end taskloop
end subroutine
```

[lldb] Support comparing FileSpec against Python strings (#190690)
We got a bug report where someone was iterating over the modules and
wanted to verify that the module name was empty and noticed it didn't
trigger.
```
for module in target.module_iter():
if module.file is None or module.file == "":
# Do something
```
My initial hypothesis was that we were somehow skipping modules, but
upon further investigation, it was the string comparison that was the
culprit. The reporter (reasonably) expected the `file` property to
return a string, but in reality it returns a SBFileSpec.
This could be avoided by explicitly comparing with an empty FileSpec,
but that seems needlessly tedious.
```
for module in target.module_iter():
if module.file is None or module.file == lldb.SBFileSpec(""):
# Do something
```
Instead, add support for comparing a SBFileSpec against a string.

[XeVM] Refactor the SPIR-V generation to use SPIR-V backend API. (#189494)
Currently, we use 2 different approach to generate SPIR-V based on
compilation target. If compilation target is `assembly/isa`, an MLIR
interface `translateToISA` is used to convert an LLVM module to SPIR-V
text. For other cases (`bin/fatbin` compilation target) SPIR-V backend
API is used to generate SPIR-V binary.
SPIR-V backend API is more powerful, as it lets one pass the necessary
extensions which is a must if one is using any advanced or
vendor-specific SPIR-V features.
This PR discontinues the usage of MLIR API and consolidates to use
SPIR-V API.
It also ensures that SPIR-V generated from MLIR side is always in binary
format (for both XeVM target and SPIR-V target).

[lldb] Skip local variable declarations at start of Wasm function (#190093)
In WebAssembly, a function starts with a number of local variable
declarations, sometimes called a function header. These declarations are
*not* instructions, but they are considered to be part of the function,
meaning we can't just pretend like the function starts on the first
instruction. Instead, we treat them like a prologue, albeit one that you
cannot disassemble or set a breakpoint on.
With this PR, we now correctly disassemble the function, matching the
output of `objdump` and breakpoints resolve to the first instruction.

Separate taskloop context and loop lowering into different operations.
This allows us to have separate operations representing the outlinable

better than the loop body to put task-local allocations:
```
omp.taskloop.context {
llvm.alloca ...
omp.taskloop {
omp.loop_nest ... {
...
}
}
omp.terminator
}
```

This commit keeps all of the clauses on the omp.taskloop op to minimise
changes that have to go into this one commit. I will follow this by
moving clauses to the operation in which they generate code.

dialects. Therefor, they could benefit from just calling a static method
which converts a bunch of enums to a correct `i32` value expected by the
AMDGCN backend.
Also renamed `TemporalHint` to `LoadTemporalHint` because it turned out
there are temporal hints for store operations (for example,
`buffer_store`) which have slightly different enum values (e.g., `WB`
(write-back) instead of `LU`)

[flang][cuda] Remove __nv_ binding names from rounding-mode intrinsics in cudadevice (#190722)
Remove name='__nv_...' from bind(c) declarations for 48 rounding-mode
functions in cudadevice.f90, allowing host,device functions to link
against the unprefixed host symbols. The __nv_ prefix for device code is
handled by a downstream pass.

[mlir][spirv] Add OpTypeSampler and OpSampledImage support (#189891)
Add missing `!spirv.sampler` type (`OpTypeSampler`, opcode 26) and
`spirv.SampledImage` op (`OpSampledImage`, opcode 86) to the SPIR-V
dialect.
The existing sampling ops (e.g. `spirv.ImageSampleImplicitLod`) consume
`!spirv.sampled_image<...>` values, but there was previously no way to
construct one from a separate image and sampler which is the standard
Vulkan pattern for combined image samplers.

[mlir][OpenMP] Move taskloop clauses to the context op (#188070)
The clauses are implemented when lowering the context op (which
generates the runtime calls, and handles the outlining of the task
function: including privatization etc). Therefore I thought it made more
sense to put the clauses on this operation rather than on the wrapped
loop.

This contradicts the ARM spec comment directly above.
Add a unit test that verifies the STR T1 encoding stores to the correct
address (base + offset).

BroadcastEventSpec owns the broadcaster class its configured to listen

The only exception here is SBListener. There are 2 methods that take
`const char *` values. However, that's handled when converting them to
StringRefs.

[flang] Added LICM hoisting for nested regions. (#190696)
This patch adds a couple of experimental LICM modes
that allow hoisting operations from regions nested
inside a loop, e.g. when there is `fir.if` inside
`fir.do_loop`. The aggressive mode hoists all operations
that are safe to hoist. The cheap mode hoists only
"cheap" operations (currently, only `fir.convert`),
though the definition of "cheap" needs to be worked out.

[CIR] Add support for variable sized array new. (#190656)
This change adds support for array new with variable size. This required
extending the cir.array.ctor operation to accept a value for the size
and a direct pointer to the element size instead of a pointer to an
array.

[LV] Update remaining tests to use VPlan cost output (NFC). (#190038)
Move remaining tests checking legacy cost output to check the VPlan's
cost model output.
In some cases, checks become much more compact (checking a single
interleave group cost vs checking the individual members which all have
the group's cost). In some cases, auto-generation consistently checks
all relevant VFs.

[BOLT][AArch64] Optimize the mov-imm-to-reg operation (#189304)
On AArch64, logical immediate instructions are used to encode some
special immediate values. And even at `-O0` level, the AArch64 backend
would not choose to generate 4 instructions (movz, movk, movk, movk) for
moving such a special value to a 64-bit regiter.
For example, to move the 64-bit value `0x0001000100010001` to `x0`, the
AArch64 backend would not choose a 4-instruction-sequence like
```
movz x0, 0x0001
movk x0, 0x0001, lsl 16
movk x0, 0x0001, lsl 32
movk x0, 0x0001, lsl 48
```
Actually, the AArch64 backend would choose to generate one instruction
```
mov x0, 0x0001000100010001
```
which is essentially
```
orr x1, xzr, 0x0001000100010001
```
We could refer to `AArch64ExpandPseudoImpl::expandMOVImm` and
`AArch64_IMM::expandMOVImm` for related implementation.
Therefore, maybe we could consider to leverage `expandMOVImm` in llvm to
optimize the mov-imm-to-reg operation in BOLT, which would help to speed
up the BOLT-instrumented binary.

Context:
https://github.com/llvm/llvm-project/pull/189785#discussion_r3019282209
Some mask instructions have a form that can potentially be optimized by
HW implementation: `vmxor.mm vd, vs, vs` and `vmclr vd, vs`, for
instance. This patch avoids using such instructions in MCA tests.

[HLSL] Rewrite inline HLSL intrinsics into TableGen (#188362)
Partially addresses https://github.com/llvm/llvm-project/issues/188345.
This PR rewrites all applicable inline HLSL intrinsics from
`hlsl_intrinsics.h` into TableGen.
The unsigned `abs` from `hlsl_alias_intrinsics.h` is also rewritten into
TableGen since it can also be defined inline.
The `NonUniformResourceIndex` is moved from `hlsl_intrinsics.h` over to
`hlsl_alias_intrinsics.h` since it can be defined as an alias.
`__detail::.*_impl` helper functions that were one liners have been
removed, and their corresponding HLSL intrinsics have been defined in
TableGen using the `Body` field instead.
Note that rewriting `refract` in TableGen instead of templates
introduces some significant changes to error messages and also
introduces a new offload test suite failure in the fp16 test because a
call to `refract(x, y, 0.5)` where x and y are half-typed vectors is
ambiguous due to 0.5 being a 32-bit float literal.
The generated `hlsl_inline_intrinsics_gen.inc` file looks like this:

In OpenMP 6.0, the 'local' clause was added to the declare_target
directive. Variables listed in the 'local' clause are considered to be
device-local. In addition, a new map clause restriction was added:
A device-local variable must not appear as a list item in a map clause.
See OpenMP 6.0 specification section 7.9.6, map Clause, Restrictions, p.

Testing:
- New error messages test for device-local variables defined in

enter/exit/update (which we'll need to address in future PRs, as this
likely should work to some extent for allocatable member mapping). A
side effect of this is that it's causing user-defined default declare
mappers to not apply in scenarios when they should.
I believe these user-defined default declare mappers should apply in all
cases where that type is mapped and no other mapper has been explicitly
specified, as they replace the original default mapping behaviour from
my admittedly shoddy specification reading skills.
The user defined default mappers should "implicitly" apply because:
1. No explicit mapper modifier is specified
2. The fallback behavior should be "as if the modifier was specified
with the default mapper-identifier" (Section 5.9)
3. The user-defined default mapper "overrides the predefined default
mapper for the given type" (Section 5.8.2)
This was 5.2-ish sectioning so information might be outdated for 6+ and
the rules might be changed (if I interpreted them correctly in the first
place).
There's a couple of other tweaks I did in the refactoring, mainly making
sure the explicit mapper can be used in conjunction with possible
specified default mappers for other types. As technically, you're
allowed to specify one mapper and map other bits and pieces in the same
mapping clause and the mapper simply doesn't apply to the other things
not of the same type.

[RISCV] Use signed target constants for XCVmem post-inc loads (#189276)
First time opening a PR against LLVM, so please let me know if anything
is missing / wrong.
This fixes an assertion in RISC-V DAG isel for CORE-V xcvmem
post-increment loads with negative immediate offsets.
`RISCVDAGToDAGISel::Select` recognizes `xcvmem POST_INC` loads and
checks whether the offset fits the signed 12-bit immediate form used by
`cv.lb/cv.lbu/cv.lh/cv.lhu/cv.lw ... , (rs1), imm12`. That path was
extracting the offset with `getSExtValue()`, but then rebuilding it with
`getTargetConstant(...)`, which takes the unsigned constant path.
For negative offsets, that could trip the APInt assertion:
```
Assertion failed: (llvm::isUIntN(BitWidth, val) && "Value is not an N-bit unsigned value")
```
during `RISC-V DAG->DAG Pattern Instruction Selection`.
The fix is to use `getSignedTargetConstant(...)` for the xcvmem
immediate case.
A regression test is added to llvm/test/CodeGen/RISCV/xcvmem.ll that
covers a reduced negative post-increment load case and checks the
expected codegen:
```asm
lw a2, 0(a0)
cv.lw a1, (a2), -4
sw a2, 0(a0)
mv a0, a1
ret
```
Reproducer before the fix:
```c
int f(int **pp) {
int *p = *pp;
int x = *p;
*pp = p - 1;
return x;
}
```
Example failing invocation:
```bash
clang --target=riscv32-unknown-elf \
-march=rv32imf_zicsr_zifencei_xcvmem \
-mabi=ilp32f -O2 -ffreestanding -c repro.c
```
Validation:
```bash
llc -O3 -mtriple=riscv32 -mattr=+xcvmem -verify-machineinstrs llvm/test/CodeGen/RISCV/xcvmem.ll
```
Confirmed the reduced repro no longer crashes

[Flang][OpenMP] Fix Common Blocks use in update to/from and target maps causing compiler errors (#187221)
This patch attempts to fix a compiler ICE when common blocks are used in
target update to/from, it seems to stem from the fact that we do not
resolve the symbols in the relevant clauses, so when we later process
the maps we don't have the right symbol that references the common block
that was setup and bound by the fortran lowering. Resolving the names
seems to do the trick.
There is a second issue where when referencing a common block with an
array contained in it and utilising the array within the target region,
we'll currently not accurately map over the bounds and cause a FIR/MLIR
verification error. The fix for this is to simply move the common block
member re-binding/re-materialization for the target region to before the
bounds data re-materialization we do during target region generation.

[lldb][DWARFASTParserClang] Handle pointer-to-member-data non-type (#189510)
## Reland Notes
Re applying [187598](https://github.com/llvm/llvm-project/pull/187598)
This is a reland of the original commit which was reverted due to a
failure on the Windows buildbot.
Root cause of the Windows failure:
* The fix introduces TemplateArgument::Declaration (pointing to a
FieldDecl)
* GetValueParamType() in TypeSystemClang.cpp did not handle this kind,
so CreateTemplateParameterList() created a
TemplateTypeParmDecl instead of a NonTypeTemplateParmDecl for the
corresponding template parameter.
* On Windows, the Microsoft name mangler calls
cast<NonTypeTemplateParmDecl>(Parm) when mangling member data pointer
NTTPs, which crashed because Parm was a TemplateTypeParmDecl.
* The Itanium mangler (Linux/Mac) does not inspect the parameter
declaration, so the bug was latent there.
Fix:
* Added TemplateArgument::Declaration to GetValueParamType() so it
returns argument.getParamTypeForDecl(), causing
CreateTemplateParameterList() to create the correct
NonTypeTemplateParmDecl.
* Removed the @skipIfWindows decorator from the test.
## Description
### Problem
MakeAPValue in DWARFASTParserClang.cpp did not handle
pointer-to-member-data non-type template parameters (e.g., template <int
S::*P>), causing LLDB to produce incorrect results or crash.
DWARF encodes pointer-to-member-data NTTPs as
`DW_TAG_template_value_parameter` with a `DW_AT_const_value`
representing the byte offset of the member within the containing struct.
MakeAPValue is responsible for converting this value into a clang
APValue, but it only handled integer/enum and floating-point types. For
pointer-to-member types, it returned `std::nullopt`.
This caused the caller (ParseTemplateDIE) to fall back to creating a
type-only TemplateArgument (kind=Type) instead of a value-carrying one.
When two specializations differ only by which member they point to
(e.g., MemberData<&S::x> / MemberData<&S::y>), both produce identical
TemplateArguments. Clang's
[findSpecialization](https://github.com/llvm/llvm-project/blob/3bc216c29cb42c7d94b617943b1d44afce605588/lldb/source/Plugins/TypeSystem/Clang/TypeSystemClang.cpp#L1674-L1677)
then treats the second as a duplicate, so only one specialization exists
in the AST. The second variable becomes unresolvable.
(See Debugger Evidence section below)
In more complex cases, this triggers an assertion failure in
[clang::CXXRecordDecl::setBases():
cast()](https://github.com/llvm/llvm-project/blob/3bc216c29cb42c7d94b617943b1d44afce605588/clang/lib/AST/DeclCXX.cpp#L219)
argument of incompatible type.
## Fix
MakeAPValue: Added `IsMemberDataPointerType()` to the integral type
check so that pointer-to-member byte offsets produce distinct APValues.
Also replaced the silent return `std::nullopt` for unsupported types
with `lldbassert` so unknown type classes are caught during development.
`ResolveMemberDataPointerToFieldDecl`: New method that follows the DWARF
chain to resolve the byte offset to the actual FieldDecl, creating
TemplateArgument(Declaration) matching clang's own AST:
DW_TAG_template_value_parameter (DW_AT_type)
→ DW_TAG_ptr_to_member_type (DW_AT_containing_type)
→ DW_TAG_structure_type → match DW_TAG_member by byte offset
If resolution fails at any step, falls through to the integer APValue
path as a safe fallback.
Verified by comparing clang's AST (clang -Xclang -ast-dump) with LLDB's
reconstructed AST (image dump ast) — both now produce TemplateArgument
decl '&S::x' referencing the correct FieldDecl.

[AMDGPU] Add DummySchedWrite to avoid multiple issue cycles (#190095)
TargetSchedule.td specifies that each explicit def of an instruction
must have an associated SchedWrite type. This is a bit unfortunate due
to the MachineScheduler handling of the ScedWrites.
Each of these different SchedWrite contribute to the number of MicroOps
for the MCSchedClassDesc for the instruction --
https://github.com/llvm/llvm-project/blob/096f9d0aa8edb8bad77e8061a6aa9cbf61bcb5ac/llvm/utils/TableGen/SubtargetEmitter.cpp#L1136
Then in the MachineScheduler.cpp's bumpNode, we grab the numMicroOps
from the MCSchedClassDesc
https://github.com/llvm/llvm-project/blob/3d7eedce5658c41a1b22775938359bfafac47fc9/llvm/lib/CodeGen/MachineScheduler.cpp#L2948
We then use this numMicroOps as how many micro ops we'll need to issue
for this instruction. For our target, the issueWidth per cycle is 1. So,
for these instructions the MachineScheduler thinks they will take
multiple cycles to issue, and we add stalls to the hazardRecognizer
https://github.com/llvm/llvm-project/blob/3d7eedce5658c41a1b22775938359bfafac47fc9/llvm/lib/CodeGen/MachineScheduler.cpp#L3100
Adding these unnecessary stalls throws off analyses in the
HazardRecognizer, which can lead to suboptimal scheduling decisions.
Due to the design, we are essentially pigeonholed into misrepresenting
these instructions. This PR adds new SchedWrite types ( WriteVALUDummy
and WriteSALUDummy ) to honor the rule of "each explicit def must have a
SchedWrite" without adding unnecessary MicroOps to get around the issue.
There are several other instructions that have exposure to this issue,
and addressing them all at once leads to lit test churn of about 170
tests. The intention of this PR is to agree upon the approach, then we
can incrementally roll it out to other instructions.

[clang] Report direct module deps for explicitly built modules (#190757)
Implicitly built modules do not include PCM paths in .d files because
the compiler is the one managing them, but for explicitly built
modules the build system needs to know about them so that if one is
deleted the build system will rebuild it.
Explicitly built modules should only report direct dependencies, as
the build system knows about each PCM in the module graph. This adds
`-fmodule-file-deps=direct` to support that, and changes dependency
scanning to use this in the explicit build commands it outputs.

[CIR][CUDA][HIP] Support stream per thread kernel launch (#188004)
Related: #175871, #179278
When `-fgpu-default-stream=per-thread` is specified, CUDA and HIP
kernels should be launched using the per-thread stream variants of the
launch API instead of the default `cudaLaunchKernel`/`hipLaunchKernel`.
This PR implements that by selecting the correct launch function name in
`emitDeviceStubBodyNew`:
For CUDA: `cudaLaunchKernel_ptsz`
For HIP: `hipLaunchKernel_spt`
This matches the behavior of the OG CodeGen implementation in
`CGCUDANV.cpp`.

[X86][APX] Fix segfault in foldMemoryOperandImpl for two-address NDD fold (#190562)
The NoNDDM code path in foldMemoryOperandImpl assumed
NewMI->getOperand(1) is always a register. When IsTwoAddr is true,
fuseTwoAddrInst replaces operands 0-4 with memory address components, so
getOperand(1) is the immediate, not a register. Calling setReg() causes
a segfault in removeOperandFromUseList.
Skip the NoNDDM COPY block when IsTwoAddr is true, since the two-address
fold already correctly handles the dest==src1 constraint.
I believe the issue was introduced with #189222 , the 'NoNDDM' block
calls 'NewMI->getOperand(1).setReg()', but after 'fuseTwoAddrInst',
operand 1 is an immediate, not a register.
Passes all APX regression tests. Unit test included in commit. Fixes
issue #190557.
First time submitting a PR to the LLVM project, please let me know if I
need to fix something! Tagging @phoebewang and @RKSimon as potential
review candidates.

[AMDGPU] Fix incorrect MachineMemOperand offsets and sizes in wide s_buffer_load splits (#189890)
When G_AMDGPU_S_BUFFER_LOAD (or its SelectionDAG equivalent) falls back
to MUBUF due to a divergent offset, wide loads (256-bit, 512-bit) are
split into multiple 128-bit chunks. Both code paths that perform this
split had bugs in how they annotated MachineMemOperand (MMO) metadata on
each chunk instruction — reporting wrong offsets and wrong sizes. This
does not affect generated assembly correctness but degrades the analysis
if that MMO metadata is used.

[CodeGen] relax kill copy hoist restriction for vreg to phys reg copies with folded loads (#190304)
Resolves: https://github.com/llvm/llvm-project/issues/62452
Currently, `TwoAddressInstructionPass` has a blanket rule against moving
kill copies, since many copies are better handled later by coalescing.
However, that rule is too strict when the kill is a virtual register to
physical register copy and the current two-address instruction has a
folded load. In that case, keeping the copy in place can force the pass
to break the folded rm form into a mov rm + op rr, even though the
physical register copy itself cannot be coalesced away in the usual
sense.
This fixes a missed optimization where a folded IMUL64rm was rewritten
into MOV64rm + IMUL64rr because a later $rax = COPY %src was kept in
place for mul.

[DA] Move no-wrap flag check into checkSubscript (#190770)
Recent patches added no-wrap flag checks to each dependence test (except
for the Banerjee MIV test) to make them sound. These fixes have been
applied one by one to ensure that each dependence test was correctly
updated and the defects were properly addressed. However, ideally, these
functions should not be called at all when the required no-wrap flags
are not set. Specifically, `classifyPair` should tag pairs as
`NonLinear` when either addrec doesn't have the no-wrap flag, which
means that the addrec is as literal non-linear.
This patch moves the existing no-wrap flag checks in the each dependence
test to `checkSubscript`, which is called by `classifyPair`. With this
change, if the addrec doesn't have the no-wrap flag, the pair will be
classified as `NonLinear` and the dependence test will not be invoked at
all. I believe this change makes the code cleaner and consistent with
the meaning of `NonLinear` classification.
Note that this patch doesn't take care of the behavioral change caused
by the Benerjee MIV test, as the test is still not sound and there are
no plans to fix it in the near future.

[Clang][HIP] Deprecate __hip_atomic_* builtins (#189897)
Emit deprecation warnings for all __hip_atomic_* builtins,
pointing users to their __scoped_atomic_* equivalents.
The warning is ignored by default, and can be enabled with
-Whip-deprecated-builtins. It will be turned on by default eventually
after we have cleaned up all ROCm/HIP headers and put a deprecation
schedule in place.
Also provide a fixit when the scope is a compile-time constant and there
is a direct mapping from the HIP builtin to a Clang builtin. The
compare_exchange builtins differ in how they accept the desired value,
so only a warning (without a fixit) is emitted for those.
This makes #185408 almost redundant for HIP, since the HIP scopes
themselves will disappear once the `__hip_*` builtins are gone. OpenCL
is different because the language itself specifies an enum. A simpler
version of #185408 can be used to emit a warning when Sema recognizes
that a non-OpenCL builtin is being passed an OpenCL scope.

[clang][ssaf] Add JSONFormat support for WPASuite (#187403)
This patch adds `JSONFormat` serialization support for `WPASuite`.
- Adds `readWPASuite` / `writeWPASuite` to the `SerializationFormat`
abstract interface and implements them in `JSONFormat`.
- Introduces `AnalysisResultRegistryGenerator`, a per-format plugin
registry template in `SerializationFormat`, allowing analysis authors to
register (de)serializers for their `AnalysisResult` subtypes with a
single static declaration.
- Extends `PrivateFieldNames.def` with `WPASuite::Data` and
`WPASuite::IdTable`, and adds a `makeWPASuite()` factory to
`SerializationFormat`, so deserialization code can construct a
`WPASuite` incrementally through the same access-controlled pattern
used for all other SSAF data structures.

[MC] Move MCTargetOptions pointer from MCContext to MCAsmInfo (#180464)
Except MC-internal `MCAsmInfo()` uses, MCAsmInfo is always constructed
with `const MCTargetOptions &` via `TargetRegistry::createMCAsmInfo`
(https://reviews.llvm.org/D41349). Store the pointer in MCAsmInfo and
change `MCContext::getTargetOptions()` to retrieve it from there,
removing the `MCTargetOptions const *TargetOptions` member from
MCContext.
MCContext's constructor still accepts an MCTargetOptions parameter
for now but is often omitted by call sites.
A subsequent change will remove this parameter and update all callers.

[clang-tidy] Fix FP in cppcoreguidelines-missing-std-forward in lambda init-list (#190522)
In `TK_IgnoreUnlessSpelledInSource` mode
[`MatchChildASTVisitor::TraverseLambdaExpr`](https://github.com/llvm/llvm-project/blob/main/clang/lib/ASTMatchers/ASTMatchFinder.cpp#L280)
only calls `match()` on each capture-init expression without recursing
into its children. So for `[t{std::forward<T>(t)}]` the `CallExpr`
nested inside the `InitListExpr` is never visited, and
`ForwardCallMatcher` never binds "call".

[flang][DoConcurrent] Map reduction variables as tofrom ByRef for device offloading (#189378)
Scalar reduction variables in `do concurrent reduce(...)` were being
mapped with `implicit ByCopy` when offloaded to device, because
`genMapInfoOpForLiveIn` treated all trivial types uniformly. This caused
the reduction result to be silently dropped — the device-side reduction
would compute the correct value but never write it back to the host.
Fix by detecting reduction variables and forcing `implicit tofrom ByRef`
mapping, matching the behavior of explicit
`!$omp target teams distribute parallel do reduction(...)`.

[lld][ELF] Merge .ltext.* input sections into .ltext output section (#190305)
## Motivation
The default output section name rules in `getOutputSectionName()`
already merge .ldata.*, .lrodata.*, and .lbss.* into their respective
output sections, but .ltext.* was missing from the prefix list. This
caused mcmodel=large builds with `-ffunction-sections` to produce a
separate output section for every function instead of combining them
into .ltext.
We actually then ran into a bunch of esoteric issues because we the had
to handle SHN_XINDEX binaries with >65535 sections, so in that sense it
helped us find those gaps :)
## Changes
Add .ltext to the prefix list alongside the other large-model section
prefixes.

[Hexagon] Fix O(N^2) compile-time regression in HexagonOptAddrMode (#189531)
In HexagonOptAddrMode::processAddUses, isSafeToExtLR was called inside
the loop over UNodeList with loop-invariant arguments. isSafeToExtLR
iterates over UNodeList, so the total work was O(N^2) in the number of
uses.
The arguments (AddSN, AddMI, BaseReg, UNodeList) do not change across
iterations. Move the call to after the loop; the function returns the
same value regardless of which iteration calls it, and the complexity
drops to O(N).
Background
----------
Commit 8c0483bba2d2 ("RegisterCoalescer: Fix assert on remat to
copy-to-physreg with subregs") introduced register coalescer
rematerialization changes that produce additional uses of A2_addi
instructions on the Hexagon backend, inflating UNodeList. This exposed
the pre-existing O(N^2) behavior in processAddUses.

[MLIR][NVVM] Add family-specific support to NVVMRequiresSM traits (#185909)
This change adds support for family-conditional SM version requirements
to the `NVVMRequiresSM` traits. The following new traits are added:
- `NVVMRequiresSMf` - Op requires an SM version belonging to one of the
given families.
- `NVVMRequiresSMaOrSMf` - Op requires one of the supported
arch-accelerated versions or an SM version belonging to one of the given
families.
This also changes the underlying checks to use the `FullSMVersion`
instead of booleans to indicate arch-acceleration and family-specific
support to simplify the checks.

This is a defesive change that aims to make sure the target data layout

explicitly rather than relying similar auto-detection implicitly.
The patch doesnt add a new test but relies on existing ones, as a test
case of different layouts would require to exhibit a misuse of the tool,
doing cross-compilation to change the layout of the compilation. The
tool is not designed to work this way.

[LV][NFC] Remove more unused function attributes from tests (#190786)
Following on from PR #188185 I've removed some more function attributes
from tests that weren't adding any value. As part of this patch I've
also removed some unnecessary `Function Attrs:` comments that live above
functions.
I suspect that there are other attributes that can be removed, for
example see ARM/arm-ieee-vectorize.ll. However, I haven't had chance to
look into these yet as they are more FP and/or target specific and
perhaps require more thought.

[NFC][AMDGPU] don't test asyncmark for non-async variants on pre-gfx12 (#190774)
The test for asyncmark on pref-gfx12 targets, checks the effect of async
marks on both async and non-async instructions. This is achieved by a
sed invocation in the RUN line to remove the .async from intrinsic name.
Such a test serves no purpose other than a minor flex. The two sets of
CHECK lines using the WITH and WITHOUT prefix are not easy to compare by
a simple eyeballing. Eliminating this hack makes it easier to add GISEL
variants later. With and without GISEL, the combinations will increase
to four instead of the current two.

[AMDGPU] Fix duplicate s_wait_asynccnt on gfx12-plus (#190906)
S_WAIT_ASYNCCNT was missing from counterTypeForInstr(), so isWaitInstr() did not recognize it as a wait instruction. On the fixpoint algorithm's second pass over a loop body, the already-inserted S_WAIT_ASYNCCNT was treated as a normal instruction, causing WAIT_ASYNCMARK to be re-processed and a duplicate S_WAIT_ASYNCCNT to be emitted.

[SPIR-V] Change DL for logical SPIR-V (#190807)
This PR originates from bogner@ draft PR. It modifies the triple for
logical SPIR-V to use the new vector sizing feature.
This means updating the tests, and fix one codegen issue:
on the old datalayout, we knew a float3 allocation size was the
same as a float4 allocation. This is now invalid, thus
a store `<4 x float>` into a `<3 x float>` allocation is UB.

Reapply "[lldb] Increase timeout on lldbutil.wait_for_file_on_target" (#190833)
Reapplication notes:
After reviewing the test failures that caused the original reverts, I'm
not convinced that this change is related. None of the test failures
failed while timing out waiting for a file.
Original Summary:
I've been tracking sporadic timeouts waiting for a file to appear on
macOS buildbots (and occasionally local development environments). I
believe I've tracked it down to a regression in process launch
performance in macOS.
What I noticed is that running multiple test suites simultaneously
almost always triggered these failures and that the tests were always
waiting on files created by the inferior. Increasing this timeout no
longer triggers the failures on my loaded machine locally.
This timeout moves from about 16 seconds of total wait time to about 127
seconds of total wait time. This may feel a bit extreme, but this is a
performance issue. While I was here, I cleaned up logging code I was
using to investigate the test failures.

[lldb] Use GetOutputStream instead of repeated AppendMessageWithFormat (#189674)
AppendMessageWithFormat is odd because it's the only AppendMessage...

This PR changes places that use it to output raw text, or build
up a large message. They now use GetOutputStream() instead,
which makes it a bit clearer that we're building one big message,
and where newlines end up.
This removes the last callers of AppendMessageWithFormat, so I am
removing it too.

[WebAssembly] Fix: fixCallUnwindMismatches after fixCatchUnwindMismatches (#187484)
`fixCallUnwindMismatches()` adds an extra try block around call sites
with incorrect unwind targets. `fixCatchUnwindMismatches()` handles
catch blocks that have incorrect next unwind destinations. Previously we
ran `fixCallUnwindMismatches()` first and then ran
`fixCatchUnwindMismatches()`. The problem is that
`fixCatchUnwindMismatches()` wraps entire try blocks which can change
the unwind destination of the calls inside. If the calls had an
incorrect unwind target to begin with, they will be wrapped already and
so the outer wrapping won't alter their unwind target. However, if they
start out with a correct unwind target, they won't get wrapped and then
that can be messed up by `fixCatchUnwindMismatches()`.
The fix is to run `fixCatchUnwindMismatches()` first.
`fixCallUnwindMismatches()` never messes up the result of
`fixCatchUnwindMismatches()` so this is the correct order.

```
This patch fixes the error by removing the STL header includes from the
`compressed_pair.h` header. Presumably the `vector` forward declaration
somehow gets pulled in via one of those headers (via `iosfwd`).
The `libcxx-simulators` tests are supposed to be STL-independent, so
removing this dependency works towards that goal.

[lldb][AArch64][Linux] Handle SME only and kernels < 6.19 (#189982)
Part of #138717.
The feature we need to use to restore non-streaming mode after an
expression enters streaming mode was only added recently in kernel 6.19.
There is no other way to restore this state, so I have adjusted the code
to use the normal FP restore path for every state other than: on an SME
only system and in streaming mode and restoring non-streaming state
If that fails, we're on < 6.19 and all we can do is accept it and
restore the rest of the register state.
I've updated the tests to check kernel version and for < 6.19 remove any
expression tests that hit this specific state. I could have set up
expected state for them, but it's basically undefined behaviour, and I
think it would make the already complex tests even worse.
Documentation now mentions the required version, and release notes link
to that documentation.
Tested on an ARM FVP configured to SME only with kernel 6.18 and 6.19,
and a Graviton 3 with only SVE.

[LLD] [COFF] Make weak aliases to implementations take priority over null pointers (#190491)
Normally, one uses weak aliases in one out of two ways.
Either one uses weak definitions to let a weak definition work as
fallback if a strong definition isn't available (which works with
link.exe as well), or as a sort of selectany COMDAT, to let multiple
weak definitions coexist, letting the linker pick any of them. (This
isn't supported by MS link.exe, but requires the LLD extension option
-lld-allow-duplicate-weak, normally implied by the mingw mode.)
Or, one uses weak references, to let a referencing translation unit
check at runtime, whether a symbol was found (at link time) or not,
optionally using the symbol.
In the latter case, the referencing object file provides a fallback
value for the weak symbol, as an absolute null symbol.
Previously, if we had multiple weak externals for the same symbol, we'd
pick any (the first one in practice); this is compatible with either of
the use cases above.
However if both use cases are combined, then we suddenly have multiple
conflicting weak externals for the same symbol; both one (or more)
symbols providing a fallback implementation for the symbol, and the
referencer that provides an absolute null pointer for the symbol.
In these cases, instead of just picking whichever choice the linker saw
first, prefer actual concrete implementations over the absolute null
symbol.
For mingw mode, this makes linking a translation unit referencing a
symbol declared with `__attribute__((weak))` work consistently if
linking it against another translation unit providing that symbol

[LLVM][CodeGen][AArch64] Improve generated code for SVE VLS truncates. (#190778)
When SVE VLS is enabled we request custom lowering for all ISD::TRUNCATE
operations involving legal types. However, we only custom lower all of
them when NEON is not available and so there are variants that do not
require SVE and can be done via NEON but we are instead falling back to
default expansion, which is this case means scalarisation. This patch
updates custom lowering to mark the variants that have isel patterns
available.

warn about conflicts in these cases, just make a clear preference and
ignore the export with lower preference.

[orc-rt] Refactor QueueingTaskDispatcher to use an external TaskQueue. (#190920)
QueueingTaskDispatcher now takes a TaskQueue by reference rather than
maintaining an internal queue. This lets API clients retain direct
access to the queue after transferring dispatcher ownership to the
Session.
TaskQueue operations (takeFirstIn, takeLastIn) are blocking: callers
wait until a task arrives or the queue is shut down. This enables a
simple client idiom:
```
QueueingTaskDispatcher::TaskQueue TQ;
Session S(std::make_unique<QueueingTaskDispatcher>(TQ), ...);
S.attach(<controller access>);
while (auto T = TQ.takeFirstIn())
T->run();
```

[lldb][AArch64][Linux] Add tests for SME only core files (#189985)
Part of #138717.
This did not require any changes to core file handling. Since a static
snapshot of an SME only system looks pretty much the same as one from
the same state on a system with SVE and SME.
For this reason, we're only testing 2 combinations. In total these
include streaming and non-streaming, ZA on and off, and 2 different
vector lengths. I think this is enough to prove that the existing code
is working.

[NVPTX] Lower nvvm.fmax to maximumnum not maxnum (#189976)
Converting nvvm.{fmin/fmax} into llvm.{min/max}num is slightly
incorrect, as {min/max}(a, sNaN) should produce "a" according to the PTX
spec, but LLVM's {min/max}num intrinsics may return either NaN or "a".
Use the {min/max}imumnum intrinsics instead for correct sNaN behaviour.
Also tidy up NVVM FMin/FMax constant-folding using these tighter
definitions of how the NVVM intrinsics map to {min/max}imum and
{min/max}imumnum.

[NVVM] Update properties for non-sync variants of the SHFL intrinsics (#189615)
Non-sync SHFL variants (shfl without .sync) are pure functions of their SSA operands and the active thread mask. Assign IntrReadMem, IntrInaccessibleMemOnly and IntrWillReturn so that: - Reading the implicit mask state is modeled for correct ordering with other convergent operations - Truly dead non-sync shfl code can still be DCE'd
Sync SHFL variants keep IntrInaccessibleMemOnly (no IntrReadMem, no IntrWillReturn) to model synchronization side effects and prevent unsafe DCE/reordering.

[LLVM][Support] add nonNull function helper (#188718)
We often see a pattern like:
```
T *ptr = doSomething()
assert(ptr && "doSomething() shouldn't return nullptr");
```
We also have functions like `cantFail`, but those are working with
Expected types.
This commits adds a `nonNull` function, which can be used inline. In
practice, one could use:
```
T *ptr = cast<T>(functionReturningT());
```
But it conveys the meaning that `functionReturningT` might return a
subtype/supertype that we actually cast.
Function behaves like the other error kinds: calls llvm_unreachable,
which may or may not trap depending on the build options. Calling this
function with `nullptr` won't build, but it makes no sense to do so.

[lldb] Bring Debuginfod's StreamedHTTPResponseHandler to SymbolLocatorSymStore (#187687)
SymbolLocatorSymStore used a simple local implementation of
HTTPResponseHandler so far. That was fine for basic usage, but it would
cause issues down the line. This patch hoists the
StreamedHTTPResponseHandler class from libDebuginfod to SupportHTTP and
integrates it in SymbolLocatorSymStore. PDB file downloads will now be
buffered on disk, which is necessary since they can be huge.
We use the opportunity an stop logging 404 responses (file not found on
server) and print warnings for all other erroneous HTTP responses. It
was more complicated before, because the old response handler created
the underlying file in any case. The new one does that only once the
first content package comes in.

distinguish `_BitInt(N)` from builtin integer types like `__int128`.
Both lower to the same LLVM integer type, but they have different ABI
rules (alignment, passing convention) on x86_64.
The flag is set during CIRGen for `Type::BitInt`, printed/parsed as
`!cir.int<s, 128, bitint>`, and excluded from `isFundamental()`.
Existing 2-arg `IntType::get()` calls continue to work via a default
parameter.

[libc++] Implement LWG4477: placement operator delete should be constexpr (#189915)
Implement the proposed resolution of
[LWG4477](https://cplusplus.github.io/LWG/issue4477).
P2747R2 made placement `operator new` constexpr since C++26, but the
corresponding placement `operator delete` was not. When a constructor
throws during placement new in a constant expression, the placement
delete is invoked and fails because it's not constexpr.
Add `_LIBCPP_CONSTEXPR_SINCE_CXX26` to placement `operator delete(void*,
void*)` and `operator delete[](void*, void*)`.

[mlir][OpenMP] Don't allow loop bounds/step from inside the task (#190827)
The omp.taskloop.context region represents what goes inside the outlined
task function. The loop bounds must be passed to the OpenMP runtime call
for taskloop and so this cannot be supported in general.
In a follow up patch I will re-allow pure operations because sinking
constants inside of the tasklooop context will be useful for something
else I am prototyping.

[lldb] Convert AppendWarningWithFormat( calls to AppendWarningWithFormatv( (#190951)
The former does not automatically add a newline like the majority of the
other AppendSomethingWithSomething calls do.
So this PR changes all but 1 use of that function to the Formatv version
and removes the explicit newline from the format strings. I also took
advantage of Formatv's ability to handle StringRef and std::string
automatically.
There is one use of AppendWarningWithFormat left, which I will address
in a follow up since it's not so straightforward.

[lldb] Remove last use of AppendWarningWithFormat( (#190958)
And remove the function entirely as there are now no
callers.
This last use of AppendWarningWithFormat does not
include a newline in the format string, but I suspect
that it should have done, so I am ok to convert it.
It was added by 56535a090d91ff10a60c884bacbd314dcf9659db,
and the other branches of the if/else will add newlines.
Also it seems like an important message that would benefit
from being on its own line.
There are no tests that expect this specific message,
which makes some sense as it seems to have been added
to cover a race condition that only sometimes happens.

[lldb/test] Replace pause() with atomic barrier in thread_filter test (#190917)
The TestFrameProviderThreadFilter test was crashing on the ARM Ubuntu CI
with an assertion in StackFrameList::GetFrameAtIndex ("A valid thread
has no frames."):
https://lab.llvm.org/buildbot/#/builders/18/builds/25501
On ARM Linux, the debugger's stop/resume cycle can cause pause() to
return (EINTR from ptrace signals), letting threads exit before the test
accesses their frames.
Replace pause() with an atomic spin-loop barrier that keeps all threads
alive in userspace at a known, unwinding-friendly location.

[X86] Fix missing ByValTemporaries update in CopyViaTemp path for musttail calls (#190540)
This fixes a miscompilation in musttail calls with byval arguments on
X86.
In the CopyViaTemp path, a temporary stack object is created and the
argument is copied into it.
However, the temporary is not recorded in ByValTemporaries,
so the final lowering phase does not emit the copy to the real outgoing
argument slot.
As a result, the callee may read incorrect values from the stack.
Fix this by recording the temporary in ByValTemporaries so that the
final lowering step correctly copies the argument to the expected stack
location.

[HLSL] Add missing Shader Model 6.0 availability for wave intrinsics (#189445)
Depends on PR #188814 to be merged first.
This PR fixes Shader Model availability for HLSL wave intrinsics so that
they all require at least SM 6.0.
Furthermore, there wasn't an easy way to specify Shader Model 6.0
availability while maintaining the requirement for Shader Model 6.2 when
16-bit types is enabled and the overload uses half types.
To fix the issue, this PR extends `_HLSL_16BIT_AVAILABILITY` to accept a
3rd optional argument that specifies the Shader Model availability when
16-bit types is disabled.
Example:
```hlsl
// If 16-bit types is enabled, require SM 6.2. Else, require SM 6.0 otherwise.
_HLSL_16BIT_AVAILABILITY(shadermodel, 6.2, 6.0)
_HLSL_BUILTIN_ALIAS(__builtin_hlsl_wave_active_all_equal)
__attribute__((convergent)) bool WaveActiveAllEqual(half);
```

[Hexagon][MIR] Serialize HexagonMachineFunctionInfo::StackAlignBaseReg to MIR (#190003)
This patch adds serialization of HexagonMachineFunctionInfo::StackAlignBaseReg
into MIR. This field stores the physical register used as the aligned-stack base pointer
when a function has both variable-sized stack objects and requires stack
alignment greater than the default.
This replaces the workaround from commit 2e10b6299591 ("[Hexagon] Add AP
register to liveins when used for frame index access") which manually added
AP to liveins. That approach was incorrect because it only updated one
block without updating predecessors, breaking liveness invariants.

[flang] Implement conditional expressions parser/semantics (F2023) (#186489)
## Implement Fortran 2023 Conditional Expressions (R1002)
***This PR contains the implementation for parsing and semantic
analysis. Lowering is implemented in a separate PR (#186490)***
Implements Fortran 2023 conditional expressions with syntax: `result =
(condition ? value1 : condition2 ? value2 : ... : elseValue)`
Issue: #176999
Discourse:
https://discourse.llvm.org/t/rfc-adding-conditional-expressions-in-flang-f2023/89869/1
-- note that some of the details provided in the RFC post are no longer
accurate
### Implementation Details
**Parser:**
- Added ConditionalExpr as primary expression (F2023 R1002)
- Right-associative chaining for multi-way conditionals
**Semantics:**
- Expression tree node ConditionalExpr<T> with N conditions and N+1
values
- Strict type checking: all values must have identical type, kind, and
rank
- Conditions must be scalar LOGICAL
**LIT Testing:**
- Parser tests: Syntax validation, precedence, nesting
- Semantic tests: Type checking, error messages
- Note: Executable tests will be added to the llvm-test-suite repo
(https://github.com/llvm/llvm-test-suite/pull/369)
**Limitations**
- Conditional arguments are not yet supported. This work is planned
- #180592
- Polymorphic types (CLASS) not yet supported in lowering
- Both limitations will emit clear error message if encountered
### Examples
```
! Simple conditional
x = (flag ? 10 : 20)
! Chained
result = (x > 0 ? 1 : x < 0 ? -1 : 0)
! Examples from F2023
( ABS (RESIDUAL)<=TOLERANCE ? ’ok’ : ’did not converge’ )
( I>0 .AND. I<=SIZE (A) ? A (I) : PRESENT (VAL) ? VAL : 0.0 )
```
AI Usage Disclosure: AI tools (Claude Sonnet 4.5) were used to assist
with implementation of this feature and test code generation. I have
reviewed, modified, and tested all AI-generated code.

[Inliner] Put inline history into IR as !inline_history metadata (#190876)
(Reland of #190700 with checks for RefSCCs with one function with a
self-reference, plus determinism fix)
(Reland of #190092 with verifier change to look through GlobalAliases)
So that it's preserved across all inline invocations rather than just
one inliner pass run.
This prevents cases where devirtualization in the simplification
pipeline uncovers inlining opportunities that should be discarded due to
inline history, but we dropped the inline history between inliner pass
runs, causing code size to blow up, sometimes exponentially.
For compile time reasons, we want to limit this to only call sites that
have the potential to inline through SCCs, potentially with the help of
devirtualization. This means that the callee is in a non-trivial
(Ref)SCC, or the call site was previously an indirect call, which can
potentially be devirtualized to call any function.
The CGSCCUpdater::InlinedInternalEdges logic still seems to be relevant
even with this change, as monster_scc.ll blows up if I remove that code.

[SelectionDAG] Recurse through mask expression trees in WidenVSELECTMask (#188085)
WidenVSELECTMask currently handles only two mask shapes: a bare SETCC

to the generic condition widening path, which often introduces
unnecessary narrow/widen roundtrips (xtn+sshll on AArch64,
packssdw+vpmovsxwd on X86).
Replace the hand-coded cases with a recursive widenMaskTree that walks
through SETCC, AND/OR/XOR, FREEZE, VECTOR_SHUFFLE, SELECT/VSELECT, and
all-ones/all-zeros BUILD_VECTORs.

https://godbolt.org/z/nrcMWWqMx
Originally in https://reviews.llvm.org/D144066, Pseudoprobes were marked
non-uniform in `isUniformAfterVectorization` even for VF=1 that allows
the `REPLICATE call @llvm.pseudoprobe` to survive until the plan is
executed when VF=1, UF=2, causing the crash.
Instead, `isUniformAfterVectorization` as true even for pseudoprobe when
`VF.isScalar()`.

is incompatible with one built with only one `-target-features

This patch moves InstCounterType and Waitcnt from Utils/AMDGPUBaseInfo.h
to a more appropriate location, one directory up, in
AMDGPUWaitcntUtils.h. We also need to move a few encoding and decoding
functions that work on Waitcnt. Some of these called static functions
defined in AMDGPUBaseInfo.cpp, like `unpackBits()`, so this patch
introduced new functions in AMDGPUBaseInfo: `decodeLoadcnt()`,
`decodeStorecnt()` and `decodeDscnt()` that do the necessary bit
operations but don't operate on the Waitcnt class directly.

[flang][OpenACC] Support DO CONCURRENT locality specs inside ACC constructs (#190406)
- Lower DO CONCURRENT locality specs (REDUCE, LOCAL, LOCAL\_INIT) that
appear inside OpenACC compute constructs and combined directives.
- Previously, any locality spec on DO CONCURRENT inside ACC hit a `TODO`
and aborted. This resolves that limitation.
- Per OpenACC 2.17.2, DO CONCURRENT without a loop construct in a
kernels construct is treated as `loop auto`; in a parallel construct it
is treated as `loop independent`. Both cases are covered.
## Mapping
| Locality Spec | ACC Operation |
|---|---|
| `REDUCE(op:vars)` | `acc.reduction` with reduction recipe |
| `LOCAL(vars)` | `acc.private` with privatization recipe |
| `LOCAL_INIT(vars)` | `acc.firstprivate` with firstprivatization recipe
|
| `SHARED` / `DEFAULT(NONE)` | No-op (variables already accessible) |
## Details
- Adds `processDoConcurrentLocalitySpecs` to convert locality specs into
the corresponding ACC data-entry operations and recipes.
- Handles the `HostAssoc` symbol indirection that DO CONCURRENT creates
for LOCAL/LOCAL\_INIT variables: after `remapDataOperandSymbols` binds
the ultimate symbol inside the compute region, the binding is copied to
the `HostAssoc` symbol so that body references resolve correctly.
- Separates `firstprivateOperands` into its own operand segment on
`acc.loop` (previously hardcoded empty).
- Fixes pre-existing build errors where `createOrGetReductionRecipe`,
`createOrGetPrivateRecipe`, and `createOrGetFirstprivateRecipe` were
called with `mlir::Type` instead of `mlir::Value` after an upstream API
change. The original variable is passed (not the acc op result) to
preserve correct recipe names.
- New FileCheck test
`flang/test/Lower/OpenACC/acc-do-concurrent-locality.f90` with 12 cases
covering REDUCE, LOCAL, LOCAL\_INIT, mixed locality, and interop with
explicit ACC clauses — across kernels regions, parallel regions, and
combined directives.

[AArch64] Add error handling for unsupported bases in lowerConstantPtrAuth (#189474)
This is part of work being done in #188378 and #188638, split out from
#188650.
`lowerConstantPtrAuth` silently miscompiled `ConstantPtrAuth` constants
with non-`GlobalValue` pointer bases — emitting `0 at AUTH(da,0)` instead
of erroring.
Changes:
- Handle `ConstantPointerNull` bases explicitly
- Error via `reportFatalUsageError` on any remaining unresolved base
(e.g. nested ptrauth) instead of silently miscompiling
This PR was mostly developed with LLM assistance

[CIR] Implement partial array destroy handling (#190834)
This implements EH cleanup handling that performs regular partial array
destruction for array constructor loops with a destructed type. Because
CIR represents array construction using an abstract operation, we do not
go through the normal EH stack mechanism. Instead, we add a partial_dtor
region to the cir.array.ctor operation indicating how a single element
should be destructed. When the cir.array.ctor operation is expanded
during LoweringPrepare, we create a cleanup scope with a partial array
dtor loop in an EH cleanup region. This gets further expanded during CFG
flattening to produce a control flow equivalent to that generated by
classic codegen.

- Improve Section 4.4 flow diagram: replace flat step-by-step diagram
with
layered version showing which architectural layer (MLIR adapter, LLVM
ABI
library, dialect-specific) owns each step.
- Note dialect-aware type mapping: dialects with custom types (e.g.
cir::IntType is not mlir::IntegerType) may need dialect-aware mapping
alongside the generic mapper to preserve signedness, pointer identity,
and
record field structure.
- Update ABIRewriteContext interface: describe the actual two-method
interface
(rewriteFunctionDefinition, rewriteCallSite) instead of the 15-20
fine-grained methods originally proposed.

[SLP][AMDGPU] Vectorize operands of non-trivially-vectorizable intrinsic calls (#189784)
A non-trivially vectorizable target intrinsic (e.g., llvm.amdgcn.exp2,
llvm.amdgcn.log) blocks the SLP vectorizer from building a deeper tree.
This patch finds the operands of such intrinsics and tries them as
independent SLP tree roots so that the operands continues to get
vectorized.
Previously, the SLP vectorizer would terminate tree building at these
intrinsic calls (as NeedToGather nodes). That left their operand chains
(loads, fmul, fsub, etc.) entirely scalar. This patch adds a new seed
discovery pass in vectorizeChainsInBlock.

[Clang] Allow musttail in noexcept functions when callee is nounwind (#190945)
noexcept functions push an EHTerminateScope onto the cleanup stack. The
musttail codegen did not know how to skip this scope, causing a "cannot
compile this tail call skipping over cleanups yet" error even when both
caller and callee are noexcept.
Skip the EHTerminateScope when the callee is nounwind (noexcept). The
callee's own noexcept handler prevents any exception from propagating,
so the caller's terminate handler is unnecessary.
Fixes #53087.

Provider IDs are now assigned by

RegisterScriptedFrameProvider

[clang][Modules] Diagnosing Module Redefinition Across ModuleMaps (#190085)
This PR enhances the module redefinition diagnostic to cover a very
specific case.
1. A module, say `B`, is discovered first during header search. In other
words, it is declared in a modulemap that shows up first on the search
paths.
2. `B` is declared again in a different modulemap, which shows up in a
later search path, and the compiler discovers `B` again when it is
searching for a different named module.
See the two tests added for examples of this specific scenario. Under
such a scenario, the compiler now reports the module redefined error.
Note that we are not diagnosing duplicating module definitions globally,
because that requires looking through all search paths and loading all
module maps, which is too expensive.

directly from our headers on MacOS. This also fixes fwrite_unlocked not
being available on MacOS which is needed for rpc_server.h.

[libc] Remove yet another batch of header template files (#191067)
This follows up on ae63230c23151c16ba68d5213da8bd5459c03a40 and remove
header templates from more C/POSIX standard headers, where templates
only used to `#include` files with macro definitions. We add this logic
to YAML instead - add entries to the `macros` list that point to the
correct `macro_header` to ensure it would be included.

[mlir][XeGPUToXeVM][XeVMToLLVM] Update the default cache-control values. (#190954)
In XeGPU, user can provide cache control value for only certain levels,
they do not have to provide cache-control value for all levels. However,
XeVM requires that each cache level must have a cache-control value. To
solve this issue, XeGPUToXeVM conversion pass adds default value to
cache-levels that does not have a user-provided cache-control value.
This PR updates this process in the following way:
- If no cache-control hint is provided for any levels, use system
default (USE_DEFAULT).
- If any of the levels has at least one cache-control value, use certain
default value for other levels.
If system default (USE_DEFAULT) is used, no cache-control metadata
annotation is necessary.

textual_hdrs is supposed to be used for header files that aren't

textual_hdrs excludes them from header parsing, which means
layering_check results aren't entirely valid. I'm going to try and
enable header parsing on these targets in a follow up change.

situation by internally using a separate enum type to represent each set

[TargetLowering] Add support for more constants to expandDIVREMByConstant. (#189286)
If we can find a chunk size k where 2^k mod divisor == -1, we can add
the even chunks and subtract the odd chunks. The resulting sum may be
negative, so we need to add 2^k + 1 (a multiple of divisor) for each odd
chunk to ensure the result is positive. We have enough extra bits
between the chunk size and HBitWidth to avoid overflow.
The idea here is similar to checking if a decimal number is divisible by
11. You can add the even digits and subtract the odd digits. If the
resulting sum is divisible by 11 the original number is divisible by 11.

[clang][ssaf] Add `JSONFormat` support for `WPASuite` (#191082)
This patch adds `JSONFormat` serialization support for `WPASuite`.
- Adds `readWPASuite` / `writeWPASuite` to the `SerializationFormat`
abstract interface and implements them in `JSONFormat`.
- Introduces `AnalysisResultRegistryGenerator`, a per-format plugin
registry template in `SerializationFormat`, allowing analysis authors to
register (de)serializers for their `AnalysisResult` subtypes with a
single static declaration.
- Extends `PrivateFieldNames.def` with `WPASuite::Data` and
`WPASuite::IdTable`, and adds a `makeWPASuite()` factory to
`SerializationFormat`, so deserialization code can construct a

[RISCV][NFC] Improve Musttail Comments/Tests (#191093)
In the Target code, this is mostly fixing typos or other comment issues.
In the musttail.ll test, this ensures the tests are more aligned with
their comments, and that the comments are accurate. I inserted some
inline asm clobbers so it's also easier to see what's going on.

In order to determine the static TLS blocks in GetStaticTlsBoundary we
iterate over the modules and try to find the largest range without a
gap. Here we might have that modules are spaced exactly by the
alignment. For example, for the failing test we have:
(gdb) p/x ranges.data_[0]
$1 = {begin = 0x3fff7f9e6b8, end = 0x3fff7f9e740, align = 0x8, tls_modid
= 0x3} (gdb) p/x ranges.data_[1]
$2 = {begin = 0x3fff7f9e740, end = 0x3fff7f9eed0, align = 0x40,
tls_modid = 0x2} (gdb) p/x ranges.data_[2]
$3 = {begin = 0x3fff7f9eed8, end = 0x3fff7f9eef8, align = 0x8, tls_modid
= 0x4} (gdb) p/x ranges.data_[3]
$4 = {begin = 0x3fff7f9eefc, end = 0x3fff7f9ef00, align = 0x4, tls_modid
= 0x1}
where ranges[3].begin == ranges[2].end + ranges[3].align holds. Since in
the loop a strict inequality test is used we compute the wrong address
(gdb) p/x *addr
$5 = 0x3fff7f9eefc
whereas 0x3fff7f9e6b8 is expected which is why we bail out in the
subsequent.

`struct sock_fprog` is not provided by glibc, but rather by the linux

implementation detail internally includes `<linux/filter.h>` somewhere
other C libs (e.g. musl) do not, which previously caused build failures
and let to disabling `struct sock_fprog` on non-glibc Linux systems.
This adds the missing include and provides it again for all Linux

Fixes: https://github.com/llvm/llvm-project/issues/100045
Adds AddedComplexity to increase the priority the pattern that matches
(or x (not y)) and generates a mov+orn instead of the original mvn+orr.
The number of instructions still stay the same but mov+orn can be
considered better than mvn+orr for two reasons:
1. Symmetry: For the same input with an 'and' instead of 'or', mov+bic
is generated.
2. Optimzation through register rename: If mov is immediate (for
example, 'mov x1, #0x4'), it can be retired early by the register
renamer and never issued for execution.

[LLVMABI] Fix build for GCC < 8 (#190974)
`llvm::abi::ArgInfo::get*` functions return `llvm::abi::ArgInfo` by
value, so we need the type to be copyable. It is not though, because of
the non trivially copyable member `MaybeAlign` (`std::optional<Align>`)
in a union, which deletes the implicit copy/move constructors and
assignment operators.
For modern GCC versions and for clang this does not present as a problem
due to named return value optimization (NRVO). It is however not a bug
in old GCC versions, because NRVO is not guaranteed. Similary
`std::optional`
could be trivially copyable, but that is also not guaranteed by the
standard.
Instead of depending on these details of the C++ implementation, move
the `MaybeAlign` member out of the union, and make it a separate member
of `abi::ArgInfo`. We lose the expressiveness from the type system that
`IndirectAttrInfo` always has a defined alignment, but we can get that
back in practice by placing asserts in the code that uses it. Therefore
`llvm::abi::ArgInfo` can still maintain this invariant.

[Clang] [MinGW] Handle `-nolibc` argument (#182062)
This implementation differs from GCC, but arguably more in line with
Unix systems, because it stops linking of default Win32 system
libraries.
On GCC it works like this:
```
❯ /ucrt64/bin/gcc -### /dev/null -nolibc 2>&1 | tr ' ' '\n' | rg '^\-l' | sort -u
-lgcc
-lgcc_eh
-lkernel32
-lmingw32
-lmingwex
-lmsvcrt
❯ /ucrt64/bin/gcc -### /dev/null 2>&1 | tr ' ' '\n' | rg '^\-l' | sort -u
-ladvapi32
-lgcc
-lgcc_eh
-lkernel32
-lmingw32
-lmingwex
-lmsvcrt
-lpthread
-lshell32
-luser32
```
Clang with this PR:
```
❯ ./bin/clang -### /dev/null -nolibc 2>&1 | tr ' ' '\n' | rg '^"\-l' | sort -u
"-lgcc"
"-lgcc_eh"
```
The motivation for supporting this argument comes from Rust, which wants
to control what is linked, but still utilize compiler builtins. With GCC
that is done by supplying `-nodefaultlibs` and `-lgcc`, but LLVM's
compiler-rt cannot be added back as easily.
`-nolibc --unwindlib=none` that skips Win32 libs would give the parity
with GCC's `-nodefaultlibs -lgcc`.

[AArch64] Avoid expensive getStrictlyReservedRegs calls in isAnyArgRegReserved (#190957)
`AArch64RegisterInfo::isAnyArgRegReserved` is used during call lowering
across all instruction selectors (SDAG, GISel, FastISel) to emit an
error if any of the arg registers (x0-x7) are reserved. This puts
`AArch64RegisterInfo::getStrictlyReservedRegs` which computes this in
the hot-path and it shows up in compile-time profiles since it's
computed for every call.
As the intent was to guard against using +reserve-x{0-7} with function
calls we can instead call `isXRegisterReserved` which is faster since
it's a simple BitVector lookup.
Compile-time improves across all instruction selectors on CTMark:
geomean
SDAG ~ -0.14%
GISel ~ -0.6%
FastISel ~ -0.7% (measured locally)
https://llvm-compile-time-tracker.com/compare.php?from=4d84263b341c3ee1847081c50e1541b62fbcb08c&to=23c4576c01d7d5e0e603366b86239e069410c3a7&stat=instructions%3Au
The numbers above are from the initial implementation that cached
`isAnyArgRegReserved`, but local experiments show instead calling
`isXRegisterReserved` is even faster. I also experimented with caching
`getStrictlyReservedRegs`, but the compile-time impact is negligible which
suggests this code isn't particularly hot and worth optimising outside of
call-lowering:
https://llvm-compile-time-tracker.com/compare.php?from=4d84263b341c3ee1847081c50e1541b62fbcb08c&to=38166d5afa9dd53320da0d47d4f056d08f0d75ca&stat=instructions%3Au
so I've also removed the FIXME from `getStrictlyReservedRegs`.

[Passes] Enable vectorizers at Oz (#190182)
The way this is handled right now is very inconsistent. When using
`-passes="default<Oz>"` (the code modified here), both vectorizers were
disabled. The clang frontend enables SLP at Oz but not LoopVectorize.
All the LTO backends enable both vectorizers at Oz.
I'm proposing here that `default<Oz>` should enable both vectorizers by
default. There seems to be a consensus that this is the right thing to
do for SLP (as both Clang and LTO backends do this). It's a bit less
clear for LoopVectorize, but given that the implementation already has
special handling for minsize functions (like switching to code size for
cost modelling and disabling various size-increasing transforms) I'm
inclined that we should also be enabling it at minsize.
This is part of trying to make optsize/minsize purely attribute based
and independent of the pipeline optimization level.

[IR] Add llvm.masked.{udiv,sdiv,urem,srem} intrinsics (#189705)
Because division by zero is undefined behaviour, when the loop
vectorizer encounters a div that's not unconditionally executed it needs
to replace its divisor with a non-zero value on any lane that wouldn't
have been executed in the scalar loop:
%safedivisor = select <vscale x 2 x i1> %mask, <vscale x 2 x i64> %divisor, <vscale x 2 x i64> splat (i64 1)
%res = udiv <vscale x 2 x i64> %dividend, %safedivisor
https://godbolt.org/z/jczc3ovbr
We need this for architectures like x86 where division by zero (or
overflow for sdiv/srem) can trap. But on AArch64 and RISC-V division
doesn't trap so we don't actually need to mask off any divisors. Not
only that, but there are also dedicated vector division instructions
that can be predicated.
Originally we tried to optimize this on RISC-V by transforming `udiv x,
(select mask, y, 1) -> vp.udiv x, y, mask`. However this isn't actually
a correct transform because the masked off lanes aren't poison, but x.
So with the safe-divisor pattern we end up losing the information that
the masked off lanes aren't actually used and can be poison.
This patch adds masked intrinsics for udiv and friends to
represent the semantics where the masked off lanes don't trap and
produce poison. This will allow AArch64 and RISC-V to emit their native
predicated division instructions and avoid the redundant select
instruction.
%res = call <vscale x 4 x i32> @llvm.masked.udiv(<vscale x 4 x i32> %x, <vscale x 4 x i32> %y, <vscale x 4 x i1> %m)

[orc-rt] Remove Session::waitForShutdown. (#191124)
The existing implementation triggered Session shutdown and then blocked
on a std::future that would be unblocked by an on-shutdown callback that
waitForShutdown had installed. Since there is no guarantee that this
callback would be the last one run, the result was that waitForShutdown
only guaranteed that it would not return until the shutdown sequence had
started (rather than completed).
This could have been fixed, but the Session destructor is already
supposed to block until the Session can be safely destroyed, so a
"working" waitForShutdown would be effectively redundant. Since it was
also a potential footgun (calling it from an on-detach or on-shutdown
callback could deadlock) it was safer to just remove it entirely.
Some Session unit tests do rely on testing properties of the Session
after the shutdown sequence has started, so a new utility has been added
to SessionTests.cpp to support this.

[SeparateConstOffsetFromGEP] Fix incorrect inbounds flag in case of non-negative index but negative offset (#190192)
Fixes #190187
Currently, SeparateConstOffsetFromGEP preserves inbounds attribute if
new sequence of GEPs from the same base pointer has non-negative offsets
in each GEP (this was mentioned in
https://github.com/llvm/llvm-project/pull/159515). This statement seems
correct for me (if the sequence consists from 2 GEPs), but current
implementation has a flaw: it checks that constant byte offset and GEP
indices are non-negative. However, in some corner cases we can have a
situation when the index is non-negative, but its offset (in bytes) is
negative, so we can't preserve inbounds attribute. In the example, GEP
index after transformation can have values
`0x7ffffffffffffffd`/`0x7ffffffffffffffe`/`0x7fffffffffffffff`; they are
all non-negative (sign bit is zero), however, after multiplication on
sizeof(i64) they become negative and inbounds can't be preserved
anymore.
The proposed fix is to check that Idx * ElementStride is non-negative
(instead of checking Idx only).

This test invokes a binary in a simulator and then reads the first line

This approach fails when the simulator itself prints a warning/error on
startup. In this case, we try to parse the error as the PID and fail.
This patch just removes the line limit. It doesn't seem to add any value
as we anyway need to search until we find the PID line, and if there is
no PID line we cannot do anything but time out eventually.

[AArch64][CodeGen] match (or x (not y)) to generate mov+orn (#191145)
Fixes: #100045
Adds a tablegen pattern that matches (or x (not y)) and generates a
mov+orn instead of the original mvn+orr.
The number of instructions still stay the same but mov+orn can be
considered better than mvn+orr for two reasons:
1. Symmetry: For the same input with an 'and' instead of 'or', mov+bic
is generated.
2. Optimzation through register rename: If mov is immediate (for
example, 'mov x1, #0x4'), it can be retired early by the register
renamer and never issued for execution.
This patch was reverted as I wanted to change my email associated with
the patch.

[clang][CIR] Add lowering for vcvt_n_ and vcvtq_n_ conversion intrinsics (#190961)
This PR adds lowering for the conversion intrinsics with an immediate
argument (identified by `_n_` in the intrinsic name), excluding FP16
variants.
It also moves the corresponding tests 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 and adds the `getFloatNeonType` helper
to support it. The remaining changes are code motion and refactoring.

[clang][ssaf] Preserve AST after codegen for SSAF extractors (#191058)
This is a use-after-free.
Codegen would drop the AST before starting the optimizations on the LLVM
IR level. This means that the ASTConsumers of the SSAF extractors only
had dangling TU Decls etc.
For now, let's override this option to force-keep the AST alive. Note
that PluginActions already did the same if their consumers were added
after the main frontend-action.
See:
https://github.com/llvm/llvm-project/blob/69e0367e8221b8002b5d438fb70ff3daf36257fc/clang/lib/Frontend/FrontendAction.cpp#L470
```c++
CI.getCodeGenOpts().ClearASTBeforeBackend = false;
```
Long term, we could think about the stability implications of running
the extractors before codegen to be able to drop the AST, thus save
memory for codegen.
However, that would mean that if any of the virtual callbacks of the
ASTConsumers (extractors) would crash/fail, it would drag down the whole
process.
If extractors would only use the HandleTranslationUnitDecl callback,
then we could wrap our `TUSummaryRunner` multiplexer in a crash-safe
`CrashRecoveryContext` - which would ensure that only the runner would
fail, but would continue for codegen.
Personally, I don't really like this continue-after-extractors-crash,
because I'd not put my life on the binary generated such an event. And
if that's the case, then what's the point...
Nevertheless, let's force keep the AST for now.

[Clang] Improve concept performance 1/N (#188421)
The concept parameter mapping patch significantly impacted performance
in scenarios where concepts are heavily used, even with
atomic-expression-level caching.
After normalization, we often end up with large atomic expressions
containing numerous duplicate and complex template parameter mappings.
Previously, we were substituting and checking these repeatedly, which
was highly inefficient.
We now cache these substitution results within TemplateInstantiator.
This saves us a lot of duplicate semantic checking and provides us some
performance improvement, as in these regression cases:
usb_ids_gen.cpp:
clang-21: 1.41s
clang-22: 3.90s
This patch: 2.45s
inspector_style_resolver.cpp:
clang-21: 18.21s
clang-22: 22.43s
This patch: 19.01s
(These regressions can be found from the original issue)
While performance is still not so good as clang-21, I think there is
still room for future improvements. E.g. We can cache invalid results
for SFINAE diagnostics, avoid redundant pack unpacking, etc.

[LV] Simplify costing partial reduction chain links (NFCI) (#190980)
Previously, `getPartialReductionLinkCost()` needed to figure out what
case `matchExtendedReductionOperand()` matched to compute a cost. This
made adding new cases to `matchExtendedReductionOperand()` more complex
and added some redundancy.
This patch updates `ExtendedReductionOperand` so that it contains all
the information needed to compute the cost ready to pass to
`getPartialReductionCost()`. This means matching new operand forms only
needs to be done in `matchExtendedReductionOperand()`.
This is split off from #188043 (this change simplifies matching absolute
difference operands).

[OMPIRBuilder] Move debug records to correct blocks. (#157125)
Consider the following small OpenMP target region:
```
!$omp target map(tofrom: x)
x = x + 1
!$omp end target
```
Currently, when compiled with `flang`, it will generate an outlined
function like below (with irrelevant bits removed).
```
void @__omp_offloading_10303_14e8afc__QQmain_l13(ptr %0, ptr %1) { entry:
%2 = alloca ptr, align 8, addrspace(5)
%3 = addrspacecast ptr addrspace(5) %2 to ptr
...
br i1 %exec_user_code, label %user_code.entry, label %worker.exit
user_code.entry:
%5 = load ptr, ptr %3, align 8, !align !19
br label %omp.region.after_alloca
omp.region.after_alloca:
br label %outlined.body
outlined.body:
br label %omp.target
omp.target:
#dbg_declare(ptr addrspace(5) %2, !20, !DIExpression(), !21)
...
br label %omp.region.cont, !dbg !23
omp.region.cont:
call void @__kmpc_target_deinit()
ret void
worker.exit:
ret void
}
```
Due to how various basic blocks are generated to implement target region
for device, the debug record for variable `x` end up in a different
block to the location of the variable (`%5` in this case). The backend
can drop such debug records.
This PR moves such records in the correct block. If the location field
of the debug record is an `Instruction`, it will ensure that debug
record is in same block as the instruction. If the location is an
`Argument`, the debug record will be moved to the entry block.
Some minor cleanup in the `UpdateDebugRecord` as that brings it to use
the similar logic as in `MoveDebugRecordToCorrectBlock`.

[AMDGPU] Use wavefront scope for single-wave workgroup synchronization (#187673)
Workgroup-scoped fences and non-relaxed workgroup atomics were
previously legalized with synchronization strong enough for multi-wave
workgroups.
When the kernel's maximum flat work-group size does not exceed the
wavefront size, the workgroup contains only a single wavefront, so
workgroup-scoped synchronization is equivalent to wavefront scope and
the stronger legalization is unnecessary.
SIMemoryLegalizer now demotes workgroup scope to wavefront scope
in this case for workgroup-scoped fences and for non-relaxed atomic
load, store, atomicrmw, and cmpxchg operations.
This allows subsequent legalization to operate at wavefront scope.
The decision is based on AMDGPUSubtarget::isSingleWavefrontWorkgroup.

[LV] Update forced epilogue VF options to allow different VFs than main. (#190393)
Previously, forced epilogue vector factors via the command line options
required to match the forced main VF (or the VF to be built in general).
This leads to a number of akward tests, where we end up with dead
epilogue vector loops.
Update the logic to build an additional VPlan with the epilogue vector
factor, and require the provided epilogue VF to be < IC * MainLoopVF.
Otherwise, epilogue vectorization is skipped.
This only impacts the forced epilogue VF option used for testing and
ensures epilogue tests to cover more realistic scenarios and make them
more robust w.r.t. to additional VPlan-based folding.

[Clang] Do not try to create invalid variable specializations. (#190960)
When a variable specialization is ambiguous,
we would still create a node for it.
If the first such specialization takes places in a sfinae context, ie
when appearing in a concept, the initial diagnostic was silence, but no
further errors were emitted on that specialization as the variable was
created anyway.
Instead we do not create a specialization in this case.

[LoopUnroll] Enable allowexpensivetripcounts when user provides pragma (#181267)
Loops with an explicit unroll pragma (`#pragma unroll` / `#pragma clang
loop unroll(enable)`) that have an expensive runtime trip count
currently don't get unrolled because `UP.AllowExpensiveTripCount`
defaults to false. The pragma is silently ignored. This is not the case
when an unroll factor is specified (`PragmaCount > 0`), where the pass
sets `UP.AllowExpensiveTripCount = true`.
**Solution:**
Set `UP.AllowExpensiveTripCount` and `UP.Runtime` to true for for loops
that have an unroll pramga at the beginning of `computeUnrollCount()`.
I've also added a new lit test `expensive-tripcount.ll` that verifies
pragma-driven unrolling with expensive trip counts will work as
expected.

[SCEV] Fix scMulExpr cost for multiply by -1 and power-of-2 (#191033)
Currently, SCEV's cost model will always return the cost of a Multiply
for `scMulExpr`, without taking into account the cases where
`SCEVExpander::visitMulExpr` does not actually emit a multiply. This PR
addresses two of these cases:
- `-1 * X`: generates `sub 0, X`
- `2^k * X`: generates `shl X, k`
This mismatch matters on targets where integer multiply is expensive
because it can block runtime unrolling by overestimating the cost of
expanding the trip count calculation.
This patch checks the constant operand in two-operand `scMulExpr` and
counts it as a subtract if it is -1 or a shift-left if it is a power of
2.
The patch also introduces a new lit test, and udpates
`IndVarSimplify/X86/loop-invariant-conditions.ll` because it now
correctly estimates the cost of `-1 * start` which allows IndVarSimplify
to simplify the induction variable.

[HIP] Fix ubsan function checks applied to kernel functions (#188872)
Summary:
The 'function' check requires inserting eight bytes of magic before each
function. The HIP runtime expects and enforces 256 byte alignment. When
the instrumentation inserts the eight bytes this is done after the
alignment, which means that the HIP runtime then points the PC to an
invalid instruction by truncating the address to 256 byte alignment. The
OpenMP runtime doesn't do this.
The purpose of this function is to handle indirect calls, and it's
impossible to indirectly call a kernel anyway, so we should just
suppress this in this case. The only other solution would be to add the
alignment back before we emit the label, but that would be meaningless
because it'd just replace the magic bytes with zeroes.

[BasicAA] Fix assertion failure in alias() caused by non-pointer base in DecomposeGEPExpression (#191180)
When stripping a bitcast in DecomposeGEPExpression, the resulting
operand may have a non-scalar-pointer type (e.g. <1 x ptr>). Proceeding
with such a type as the decomposition base violates the AA assumption
that all pointers are scalar pointer types, triggering an assertion
failure on alias() call.
Add a type check in the bitcast/addrspacecast handling path to return
not stripped V as base when the stripped operand is not a scalar pointer
type.
Add a lit test verifying no crash on valid IR containing such a bitcast,
and checking that the alias query conservatively returns MayAlias.
Fixes #191157

Reland [MC] Fuse relaxation and layout into a single forward pass (#190318)
This relands debb2514ea7f, which was reverted by #189548 due to ARM
spurious `cbz` out of range error (Chromium, Android).
---
Replace the two-pass inner loop in relaxOnce (relaxFragment +
layoutSection) with a single forward pass that sets each fragment's
offset before processing it.
- Extract relaxAlign from layoutSection's FT_Align handling and call
it from relaxFragment. FT_Align padding is computed inline with the
tracked Offset, so alignment fragments always see fresh upstream
offsets. This structurally eliminates the O(N) convergence pitfall
where stale offsets caused each iteration to fix only one more
alignment fragment.
- The new MCAssembler::Stretch field tracks the cumulative upstream size
delta. In evaluateFixup, for PCRel fixups during relaxation, Stretch
is added to forward-reference target values (LayoutOrder comparison).
This makes displacement = target_old - source_old, identical to the
old two-pass approach, preventing premature relaxation for
span-dependent instructions.
- FT_Fill/FT_Org removed from relaxFragment; `if (F.Offset != Offset) in
the fused loop detects their size changes.
- layoutSection is retained for initial layout and post-finishLayout.
This fixes the FT_BoundaryAlign linear time convergence issue reported
by #176535. In addition, backward branches near the short/near boundary
may benefit from tighter encoding when a .p2align between the target and
the branch absorbs upstream growth (see relax-branch-align.s).
Key commits that updated relaxFragment/layoutSection:
- 742ecfc13e8a [MC] Relax MCFillFragment and compute fragment offsets
eagerly
- 9f66ebe42715 MC: Eliminate redundant fragment relaxation
- df71243fa885 MC: Evaluate .org during fragment relaxation
- b1d58f025e83 MCAssembler: Simplify fragment relaxation
- 58d16db8b5d2 MCAssembler: Simplify relaxation of FT_Fill and FT_Org
---
Fix for the ARM regression (see thumb-ldr-stretch.s):
ARM `evaluateFixup` pre-seeds Value with
`(F.Offset + fixup_offset) % 4` for Thumb's AlignDown(PC, 4) semantics.
The full displacement formulas:
```
Old two-pass:
(source_old % 4) + target_old - source_old
= target_old - alignDown(source_old, 4)
Reverted buggy fused:
(source_new % 4) + target_old - source_new + Stretch
= target_old + Stretch - alignDown(source_new, 4)
Fixed fused:
((source_new - Stretch) % 4) + target_old - source_new + Stretch
= (source_old % 4) + target_old - source_old
= target_old - alignDown(source_old, 4)
```
With the fused pass, F.Offset is already updated by Stretch, so the
pre-seed used the new offset while the generic Stretch compensation
assumed the old offset, producing a misaligned displacement. This caused
spurious tLDRpci -> t2LDRpci relaxation (+2 bytes each), which cascaded
to push the initial CBZ target out of range.
The fix uses pre-Stretch source offsets for the AlignDown(PC, 4)
pre-seed in evaluateFixup, leading to the same displacement
as the old two-pass algorithm.

Add a simple one-liner redirecting header to fix this compatibility

Also, given that it's effectively a compatibility shim, YAML generation

Summary:
This function is supposed to manage the doorbell interrupts. The flow
that was intended was that the client notified work to wake the server
and the server finished the work so it didn't go back to sleep until
everything was done. This was reversed and we had the client finishing
work and then stalling on it.

[flang] preserve logical operations in single FIR operation (#190771)
This patch adds new operations to represent AND/OR/EQV/NEQV logical
operation with the main goal of preserving them at a higher level in the
IR to make it easier to match them and to dispatch them to atomic
implementations when working on reductions.
They are only generated when one of the argument is actually a logical,
otherwise, the when dealing with AND/OR... where both operands are
comparisons, the i1 arith operations are still generated since using the
new operation would make the IR more complex and preserving logical
operation is only valuable when one of the operand is a logical
variable.

relates: https://github.com/llvm/llvm-project/issues/190538
related PR: https://github.com/llvm/llvm-project/pull/190787
This PR folds (sext(ucmp/scmp(X, Y)) -> ucmp/scmp(X, Y). Since ucmp/scmp
return -1, 0, 1, if you see the sequence:
```llvm
%_3 = tail call i8 @llvm.ucmp.i8.i64(i64 %a, i64 %b)
%_0 = sext i8 %_3 to i64
```
It's fine to turn this into:
```llvm
%_0 = tail call i64 @llvm.ucmp.i64.i64(i64 %a, i64 %b)
```
[Alive Proof](https://alive2.llvm.org/ce/z/VmeKM2)
Likewise for scmp:
```llvm
%_3 = tail call i8 @llvm.scmp.i8.i64(i64 %a, i64 %b)
%_0 = sext i8 %_3 to i64
```
```llvm
%_0 = tail call i64 @llvm.scmp.i64.i64(i64 %a, i64 %b)
```
[Alive Proof](https://alive2.llvm.org/ce/z/WSm7YS)
For ucmp, a simple way to get this is to cmp two rust unsigned integers:
```rust
pub fn compare(a: u64, b: u64) -> i64 {
a.cmp(&b) as i64
}
```
Which gets this:
```llvm
define noundef range(i64 -1, 2) i64 @compare(i64 noundef %a, i64 noundef %b) unnamed_addr {
start:
%_3 = tail call i8 @llvm.ucmp.i8.i64(i64 %a, i64 %b)
%_0 = sext i8 %_3 to i64
ret i64 %_0
}
declare range(i8 -1, 2) i8 @llvm.ucmp.i8.i64(i64, i64)
```
For scmp, swapping to i64s will suffice:
```rust
pub fn compare(a: i64, b: i64) -> i64 {
a.cmp(&b) as i64
}
```
```llvm
define noundef range(i64 -1, 2) i64 @compare(i64 noundef %a, i64 noundef %b) unnamed_addr {
start:
%_3 = tail call i8 @llvm.scmp.i8.i64(i64 %a, i64 %b)
%_0 = sext i8 %_3 to i64
ret i64 %_0
}
declare range(i8 -1, 2) i8 @llvm.scmp.i8.i64(i64, i64)

[RISCV] Improve lowering of llvm.vector.reduce.mul (#190628)
RVV doesn't have a vredprod instruction, so we're forced to emulate
these.
The current ExpandReductions lowering which gets used trips an
unfortunate
behavior with exact VLEN - we end up with a bunch of vsetvli toggles
caused
by an interaction with lowerShuffleViaVRegSplitting. We end up doing all
the sub-m1 shuffles at m1, but don't recognize that we could do the
multiplies in m1 as well. As a result, we end up toggling back and forth
between LMULs.
This change is somewhat of a blunt hammer; it adjusts the lowering to
do the greater than m1 lowering via the current strategy, then do
a vector.extract, then do the same shuffler reduction lowering on
the smaller type. This has the effect of fixing the exact VLEN case,
and improves register pressure for all cases. The cost is that we end
up with an exact vsetvli to toggle to the m1 type before the sub-m1
portion of the reduction.
This helps all configurations, but particularly helps machines
with large VLENs as there are more reduction steps which can be
performed at m1.
An alternative design would be to try and reduce the LMUL of the
multiply steps, but we've generally shied away from that to date, so
this is side stepping that issue.

This change adds a canonicalizer for CleanupScopeOp that erases any

the body region into the block in place of the cleanup scope op. It also
erases any EH-only cleanup scope whose body region contains only a yield
operation, dropping the cleanup region contents even if they were not
trivial because the EH cleanup is not reachable in this case.

[InstCombine] Restore narrowing of double to float for integer casts (#190550)
Resolves #190503
This patch modifies `visitFPTrunc` to simplify the following expression:
```llvm
fptrunc(OpI (sitofp/uitofp x), (sitofp/uitofp y))
```
to
```llvm
OpI (sitofp/uitofp x), (sitofp/uitofp y)
```
`getMinimumFPType` now calls `canBeCastedExactlyIntToFP` on `x` and `y`.
This allows a double to be narrowed to a float if the source operands originate from sitofp/uitofp and can be represented exactly in the target float type.
This fixes a regression pointed out in the issue, where `visitFPExt` began folding `fpext(sitofp)` into `uitofp nneg i64 %x to double`, causing `visitFPTrunc` to lose the `fpext` it relied on to recognize the narrowing opportunity. On certain target, this would cause more expensive operations (i.e, division with f64 instead of f32).

For append()/assign(), implement a version that uses emplace_back() in

append() elements first and then rotate them into their correct
position.

This patch introduces the following changes:

struct pairs a file path with its resolved `SerializationFormat`.
- Consolidates duplicated input/output path validation logic from
`SSAFLinker.cpp` and `SSAFFormat.cpp` into shared
`FormatFile::fromInputPath()` and `FormatFile::fromOutputPath()` methods
in `Tool/Utils.{h,cpp}`
- Moves error message constants from the public header into the `.cpp`
file and rewords them.
- Removes per-tool local error messages and filesystem logic that are
now handled centrally.
- Updates all affected lit tests to match the new error message wording
and adds a test for directory-as-input.

NVPTXAsmPrinter currently buffers one element at a time while generating

with sub-byte datatype (like i4) since we allocate lesser buffer size.
This PR fixes the printer to merge consecutive elements to form a full
byte before buffering.

SymbolizableOjbectFile: Convert Wasm file offset to section offset for DWARF (#191068)
Wasm's object and linking format lacks virtual addresses like ELF et al.
As a result, linked files generally use file offsets as "addresses",
whereas
objects and DWARF sections use code section offsets.
This has led to incorrect interpretation of addresses in llvm-objdump
and llvm-symbolizer for linked files.
This change to SerializableObjectFile checks the input ModuleOffset, and
if it falls within a wasm code section, adjusts it to a section offset
before querying the DwarfContext. (For object files, Sec.getAddress() is
0 so it works for object files too). It extends the existing DWARF test
for llvm-symbolizer to include a linked file, and also adds an
equivalent for objdump.
Fixes #129523

[ADT] Refactor post order traversal (#191047)
Currently, po_iterator holds the traversal state. This makes copying
and moving po_iterator fairly expensive and the code cannot be optimized
away in several cases (most of it isn't even inlined in a default
build).
Therefore, refactor post-order traversal to hold the state in a wrapper
class with cheap iterators. Additionally, replace po_storage base class
with a CRTP implementation where users can provide their own storage.
Benefits:
- Performance in stage2-O3 improves by 0.19% instructions:u and even
more substantially in cycles/wall-time.
- Users that use a custom storage/iteration limitation can do so in a
more clean way by subclassing PostIteratorTraversalBase. See e.g.
LoopBlocksTraversal.
- For graphs with block numbers, reserving can now be implemented
reasonably easy (not done yet).
Implications:
- PostOrderTraversal::iterator is no longer a forward iterator. This
property was never really used, though.
- PostOrderTraversal must be live while iterators are live. For typical
uses (for (X x : post_order(...))), this is no problem, but could end
up being problematic if the iterator is wrapped (e.g.
for (X x : make_filter_range(post_order(...), ...)) -- problematic,
because make_filter_range doesn't preserve the range but only the two
iterators, which become invalid as the for loop is entered). This is a
limitation of the way LLVM implements ranges.

This is primarily cleanup after the somewhat recent successor changes.
There's also a minor (barely measurable) performance improvement here.

Where the result is a type with C bits. The unsigned compare on the
select treats negative values as large positive values so any value
that isn't in the range [0, (1 << C) - 1] will use the True operand
of the select. The sext(X >s -1) creates all ones for positive values
of X and 0 for negative values of X.
This pattern appears in the picojpeg workload of embench-iot with

depends on which headers were included prior.
This adds a diagnostic for such cases when they can be detected, and
informs the user to use a textual forwarding header instead.
This bypasses Clang's FileManager and VFS as they don't know about
symlinks. The diagnostic is worded as "may" because of this.

[RISCV][P-ext] Add mul*.h00 and mul*.w00 patterns. (#191313)
The instructions take the low halfword/word from each input, extends
them and multiplies to produce a word/dword result.
We can use these instead of plain MUL if it would allow us to avoid
a sext/zext for at least one of the operands.
Tests were written by Claude Sonnet 4.5.

[lldb] Fix ScriptedFrame thread member init assignment (#191297)
This patch fixes a typo in the `ScriptedFrame` base class initializer
where we used a thread id with `GetThreadByIndexID` instead of the
thread index.
This could lead to issues where derived classes wouldn't be initialized
properly, which could cause crashes down the line.
The patch addresses the issue by calling `GetThreadByID` with the thread
id.

[Object] Extract format-agnostic BBAddrMap decoder
This is part of patches to port BBAddrMap to COFF.
Move format-agnostic BBAddrMap decode logic out of ELF.cpp into
BBAddrMap.cpp, and expose a shared decodeBBAddrMapPayload helper in
BBAddrMap.h.
Keep ELF-specific steps (section decompression and relocation
translation) in ELF.cpp, and delegate payload decoding to the
shared helper.
Error messages in the decoder are updated to use the generic
"BB address map" instead of the ELF-specific "SHT_LLVM_BB_ADDR_MAP"
since the decoder is now shared across object formats.
This refactor prepares follow-up work to let COFF and ELF share
the same BBAddrMap decoding logic.

[clang][Serialization] Serialize DiagStateOnPushStack to fix pragma d… (#190420)
**Serialize DiagStateOnPushStack to fix pragma diagnostic push/pop
across PCH boundary**
`DiagStateOnPushStack` was not serialized in PCH files, causing `#pragma
clang diagnostic pop` to emit a spurious "no matching push" warning when
the corresponding push was in the preamble. This is because clangd
splits files into a preamble (compiled to PCH) and the main file body,
and the push/pop stack was lost during the PCH round-trip.
Serialize and deserialize DiagStateOnPushStack in
`WritePragmaDiagnosticMappings`/`ReadPragmaDiagnosticMappings` so that
unmatched pushes from a preamble are correctly restored.

[SelectionDAG] Salvage debuginfo when combining load and z|s ext instrs. (#188544)
Reland 2b958b9ee24b8ea36dcc777b2d1bcfb66c4972b6
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.

[mlir][NVVM] Add InferTypeOpInterface to NVVM MBarrier ops with deterministic result types (#188173)
Add result type inference to 5 NVVM ops whose result types can be fully
determined from their operands and attributes. This enables the Python
binding generator to emit `results=None` as a default parameter,
removing the need for callers to pass explicit result types.
Ops with optional results (using `InferTypeOpAdaptorWithIsCompatible`):
- `MBarrierArriveOp`: i64 for non-cluster pointers, no result for
shared_cluster
- `MBarrierArriveDropOp`: same as above
- `MBarrierArriveExpectTxOp`: same, plus no result when predicate is set
- `MBarrierArriveDropExpectTxOp`: same as MBarrierArriveOp
- `BarrierOp`: i32 when reductionOp is present, no result otherwise
The optional-result ops use a permissive `isCompatibleReturnTypes` that
allows omitting the result, preserving backward compatibility with the
existing zero-result assembly form.
Also updates the NVGPUToNVVM conversion to work with the new inferred
result types for `MBarrierArriveOp` and `MBarrierArriveExpectTxOp`.
This is a source-breaking change for Python callers that pass result
types positionally (e.g. `mbarrier_arrive(res, addr, ...)` becomes
`mbarrier_arrive(addr, *, ..., results=None, ...)`). Existing MLIR
assembly is fully backward compatible.

Previous use of `Min` for `ptrauth-elf-got` and
`ptrauth-sign-personality` module flags was introducing a risk of silent
decrease of security during module merge. The previous choice for `Min`
was mimicking the behavior for the `sign-return-address*` family of
module flags, but it does not make sense to apply this behavior here.

[AMDGPU] Improve max3/min3 formation for tree-structured reductions (#190734)
The existing `performMinMaxCombine` forms `max3` by matching
`max(max(a,b), c) -> max3(a,b,c)`. For tree reductions like
`max(max(a,b), max(c,d))`, this produces `max3(a, b, max(c,d));` placing
`max3` on top. At the next tree level, `max(max3, max3)` cannot combine
because the 3-op opcode (`FMAXIMUM3`) differs from the 2-op opcode
(`FMAXIMUM`).
This patch:
1. Adds a tree combine: `max(max(a,b), max(c,d)) -> max(max3(a,b,c),
d)`, keeping a 2-op node on top that enables further combining.
2. Defers the existing combine when the operand is a tree node whose
children can still be combined, ensuring inner tree levels are optimized
before outer levels consume them.
Deferral is skipped when neither child has a single use, since the inner
combine cannot fire in that case.

[opt] Add -mtune option (#187932)
This patch adds a Clang-compatible -mtune option to opt, following up
the addition to llc: https://github.com/llvm/llvm-project/pull/186998,
to enable decoupled ISA and microarchitecture targeting. Example use
case is `MaxInterleaveFactor` for the loop vectorizer.
The implementation registers the new codegen flag for opt, which
consumes it and sets tune-cpu attributes for functions to be consumed by
the backend.

[AMDGPU][Doc] GFX12.5 Barrier Execution Model (#185632)
- Document GFX12.5-specific intrinsics.
- Rename signal -> arrive, leave -> drop to match C++ terminology.
- Update execution model to support GFX12.5 semantics (e.g. threads can
arrive w/o waiting)
- Various clean-ups & wording updates on the model.
- Added "mutually exclusive" barrier objects.
- Added barrier-phase-with + related constraints.
- Document that barriers can exist at cluster scope too.
- Update GFX12 target semantics/code sequences to include GFX12.5.
The model is no longer marked as incomplete, it is now just
experimental.
There are more updates planned in the future to support more features,
and
improve some known shortcomings of the model. e.g., currently many
relations
encode too much semantic information, which means the model doesn't
build
when barriers aren't used correctly. I'd like the model to eventually
represent
broken executions as well, just like a memory model can.

[lldb][Process/FreeBSDKernelCore] Defer actual core loading to DoLoadCore() (#186626)
`ProcessFreeBSDKernelCore` initializes `m_kvm` in class initialization,
thus invoking `kvm_open2()` only once. Although this approach is
effective, it violates the expected bahaviour of `DoLoadCore()`, loading
core file before the function is invoked. Later when I implement another
flavour of `ProcessFreeBSDKernelCore` inherited from `ProcessElfCore`,
ELF plugin will load core in `DoLoadCore()` while kvm plugin will do so
in the class initializer, causing discrepancy between the two classes.
Like the kvm/fvc precedent, the plugin variant (ELF and kvm) will be
chosen using vtable override, so if the behaviour differs like above, it
gets harder to add new features and debug the code. Thus, detecting and
loading core file in `ProcessFreeBSDKernelCore` should be handled
separately.

[lldb][Process/FreeBSDKernelCore] Add command for refreshing thread list (#188692)
Since `/dev/mem` is live memory, its thread list is updated while
running LLDB. In the current model, users need to restart LLDB to get
new thread list, and this is prone to error when writing to memory
because LLDB's thread information and `/dev/mem` might be out of sync.
The new command `process plugin refresh-threads` reconstructs thread
list so users can synchronize thread list without restarting lldb.
Memory cache needs to be cleared prior to reconstruction otherwise lldb
will read the same process information from cache memory. To invoke
`UpdateThreadList()` from `UpdateThreadListIfNeeded()`, clear thread
list as well before triggering an update.
This is enabled for all kvm invocation regardless of type of the target
(crash dump or live kernel) because kvm hides the target type
information. Elf-core based implementation in future will need to update
thread list only at the first time as it is guaranteed that elf-core
handles static files.

while building the inferiors. Given that the triple is a superset of the
arch, it is strictly more expressive.

[analyzer][NFC] Document getVarRegion shortcomings (#191168)
... more precisely, that the analyzer currently uses `NonParamVarRegion`

In my recent commit f40c234191802154d5b3fc3209908c3f2d6e1649 I added a
FIXME note to the method `MemRegionManager::getVarRegion`, but now, as I
tried to implement that I realized that the situation is more complex.
As I don't have time to fix this right now, I'm pushing this commit to
remove the inaccurate FIXME and replace it with more accurate TODO notes
that explain the current (problematic) behavior of the codebase.

[Clang] Pass toolchain paths unconditionally in linker wrapper (#191311)
Summary:
Previously we used the auto-forwarding mechanism to handle options like
forwarding --cuda-path. The problem is that this went over the toolchain
options and that meant if someone used just bare `--offload-link` there
would be no CUDA or ROCm toolchain to figure out if we should forward
it. Just do this unconditionally for all toolchains, there's no harm in
setting it if it's unused.

[SystemZTTI][CostModel] Improve SystemZ cost model for scalar Read-Modify-Write Sequence, Fix #189183 (#190350)
This patch improves the SystemZ cost model to identify Read-Modify-Write
sequences
that can be folded into a single instruction (e.g., ASI, NI, OI).
If a load, a scalar arithmetic operation (ADD, SUB, AND, OR, XOR) with
an
immediate, and a store all target the same memory location and have no
external uses, the cost of the arithmetic and store insn should bw 0.
This implementation does not include TTI::TCK_RecipThroughput CostKind,
as
it causes regression in non-power-2-subvector-extract.ll.
Fixes #189183. (Refer it for example)

[llvm-dwarfdump][LineCov 2/3] Add coverage baseline comparison and line table coverage in isolation (#183790)
Patch 2 of 3 to add to llvm-dwarfdump the ability to measure DWARF
coverage of local variables in terms of source lines, as discussed in
[this
RFC](https://discourse.llvm.org/t/rfc-debug-info-coverage-tool-v2/83266).
This patch adds the ability to compare a variable’s coverage against a
baseline, e.g. an unoptimised compilation of the same code. This is
provided using the optional `--coverage-baseline` argument.
When a baseline is provided, the output also includes a per-variable
measure of the line table’s coverage (`LT`, `LTRatio`), distinct from
the variable’s coverage proper. See section 2.2 of the RFC for details
on this metric.

[lldb][Process/FreeBSDKernelCore] Fix thread ordering (#187976)
In #178306, I made an incorrect assumption that traversing `allproc` in
reverse direction would give incremental pid order based on the fact
that new processes are added at the head of allproc. However, this
assumption is false under certain circumstance such as reusing pid
number, thus failing to sort threads correctly. Without using any
assumption, explicitly sort threads based on pid retrieved from memory.

obtain the numeric values of expressions, using the analyzer directly
may be necessary, which requires SemanticsContext to be provided.

[compiler-rt] Expose shared DSO helpers for compiler-rt runtimes (#191098)
The motivation of this PR is to refactor and expose DSO helper functions
so
they can be used by all compiler-rt libraries, including the profile
library,
without duplicating dlopen/dlsym (non-Windows) or
LoadLibrary/GetProcAddress
(Windows) logic in each runtime.
Implement the helpers in namespace __interception in
interception_linux.cpp for
non-Windows targets and interception_win.cpp for Windows, and use them
from the
existing Linux interception path for RTLD_NEXT/RTLD_DEFAULT/dlvsym
lookups.
This is NFC for existing libraries that already use interception's
public APIs;
sanitizer and interception lit behavior is unchanged.

[BOLT] Fix iterator bugs (#190978)
Fix iterator misuse in four BOLT passes, caught by _GLIBCXX_DEBUG
(enabled via LLVM_ENABLE_EXPENSIVE_CHECKS=ON).
* AllocCombiner: combineAdjustments() erases instructions while
iterating in reverse via llvm::reverse(BB), invalidating the reverse
iterator. Defer erasures to after the loop using a SmallVector.
* ShrinkWrapping: processDeletions() uses
std::prev(BB.eraseInstruction(II)) which is undefined when II ==
begin(). Restructure to standard forward iteration with erase.
* DataflowAnalysis: run() unconditionally dereferences BB->rbegin(),
which crashes on empty basic blocks (possible after the ShrinkWrapping
fix). Guard with an emptiness check.
* IndirectCallPromotion: rewriteCall() dereferences the end iterator via
&(*IndCallBlock.end()). Replace with &IndCallBlock.back().
* TailDuplication: constantAndCopyPropagate() uses
std::prev(OriginalBB.eraseInstruction(Itr)) which is undefined when Itr
== begin(). Restructure to standard forward iteration with erase.

[OpenMP][OMPT] Fix `omp_control_tool` before any directive (#191429)
When a user calls `omp_control_tool`, a tool is attached and it
registered the `ompt_control_tool` callback, the tool should receive a
callback with the users arguments.
However, in #112924, it was discovered that this only happens after at
least one host side directive or runtime call calling into
`__kmp_do_middle_initialize` has been executed.
The check for `__kmp_init_middle` in `FTN_CONTROL_TOOL` did not try to
do the middle initialization and instead always returned `-2` (no tool).
A tool therefore received no callback. The user program did not get the
info that there is a tool attached. To fix this, change the explicit
return to a call of `__kmp_middle_initialize()`, as done in several
other places of `libomp`.
Further handling is then done in `__kmp_control_tool`, where the values
`-2` (no tool), `-1` (no callback), or the tools return value are
returned.
Also expand the tests to introduce checks where no callaback is
registered, or `omp_control_tool` is called before any OpenMP directive.
Fixes #112924

[gsymutil] Fix a warning on systems with 32-bit `off_t` (#189524)
The size of `off_t` isn't specified, so it can be either 32 or 64 bits
depending on the system. In particular, on LLP64 systems like windows
it's generally only 32 bits. This means the `if (StrtabSize >
UINT32_MAX)` check added in #181458 may warn on such systems (Giving
-Wsign-compare).
Given that `FileWriter::tell` (and the underlying `raw_ostream::tell`)
explicitly return `uint64_t`, the simplest fix is to just use the return
type of the function instead of potentially truncating. Since the same
logic applies even where we don't happen to have a warning here, I've
applied this for all of these uses of `off_t`.

[Clang] Permit '--target=amdgcn--' for binaries (#191451)
Summary:
We always accepted `--target=amdgcn--` to create IR object files but it
doesn't allow creating actual binaries without user intervention. This
is because it would fall-through to the GCC toolchain which does not
know how to handle AMGCN / AMDGPU targets. This PR just adds a single
line to handle it, which effectively allows this as a 'bare' target.
Perhaps the argument could be made that AMDGPU should not support
anything but strictly HSA because it has many assumptions in the
compiler itself, such as implicit arguments, but I feel like it is
relatively harmless to support this case if users decide they really do
not need it.

Strip .llvm. suffix after removing the coroutine suffixes to avoid breaking pseudo probe (#191354)
Pseudo probe is currently broken when a coroutine function is promoted
with a global name during ThinLTO import. The top-level function GUID in
.pseudo_probe section are computed from the promoted name (with
".llvm.xxxx" suffix) instead of the original function name. Then it will
cause a dangling top-level GUID that doesn't have any reference in the
pseudo probe desc, and potentially hurt profile quality.
The root cause of the issue were:
1) ThinLTO post-link imports and promotes a local coroutine function,
creating a global function with ".llvm.xxxx" suffix.
2) https://github.com/llvm/llvm-project/pull/141889 introduces a change
in CoroSplit pass that updates the coroutine functions linkage name with
the ".cleanup", ".destroy", ".resume" suffixes, and this creates
top-level functions with ".llvm.xxxx.cleanup", ".llvm.xxxx.destroy",
".llvm.xxxx.resume" suffixes.
3) PseudoProbePrinter and PseudoProbeInserter only strips coroutine
suffix, and didn't consider the ".llvm." suffix.
This patch fixes the issue in step 3)

[ADT][NFC] Make po iterator stack entry trivially copyable (#191290)
std::tuple is not trivially copyable, leading to the use of less
efficient SmallVector implementations. Additionally, named members are
more readable than std::get<N>.
Also make sure that successors() is called only once per traversed basic
block -- this is difficult here: when the begin iterator is stored in
the vector between the calls, the second call can't be eliminated due to
the potentially visible store. When copying the entry into the vector,
SmallVector exposes the address of the alloca via ptrtoint to ensure
that the object indeed doesn't reside in the vector. We're missing
some optimization here... so very carefully work around this problem.

but neither the commit message or the reviews actually justify using
this calling convention. The actual behavior which is important for that
change is the way clang calling convention lowering works.
There isn't really any other reason to use spir_kernel: every non-SPIR
target either rejects it, or treats it as the C calling convention. So
let's stop doing it.

Invalid LoopInfo gets passed into `simplifyLoopAfterUnroll()` and is
further called by SCEV at the beginning of
`ScalarEvolution::createSCEVIter()`, which triggered hidden bugs. To
fix, updated LoopInfo correctly before its use.
The loop blocks that `simplifyLoopAfterUnroll()` iterates
through, will become unavailable after the LoopInfo update. Therefore we
store the loop blocks beforehand for its use in
`simplifyLoopAfterUnroll()` later.

Disable MSVC-incompatible portions of `disable_container_overflow_checks` for MSVC (#191456)
**Context:**
The test `disable_container_overflow_checks` recently started running on
Windows, as per:
https://github.com/llvm/llvm-project/pull/181721/changes
As a result, the MSVC ASan fork of LLVM ASan started executing this
test, which has been failing for 2 reasons.
1) MSVC does not support the `__has_feature` syntax.
2) The `__SANITIZER_DISABLE_CONTAINER_OVERFLOW__` macro is not supported
in MSVC ASan (we have an equivalent in `_DISABLE_STL_ANNOTATION`)
because `__SANITIZER_DISABLE_CONTAINER_OVERFLOW__` also invokes
MSVC-incompatible syntax.
**This PR** addresses these two failures.
For (1), we replace:
```C++
#if __has_feature(address_sanitizer)
```
with
```C++
// compilers such as MSVC do not support `__has_feature`
#ifndef __has_feature
#define __has_feature(x) 0
#endif
// MSVC defines `__SANITIZE_ADDRESS__`
#if __has_feature(address_sanitizer) || defined(__SANITIZE_ADDRESS__)
```
and for (2), we disable the tests for
`__SANITIZER_DISABLE_CONTAINER_OVERFLOW__` for MSVC.

[AMDGPU] IGroupLP: Fix BestCost assignment in greedy solver (NFC) (#186995)
The greedy solver's greedyFind method incorrectly reports the cost of
the last processed group instead of the best one. In practice, this does
not have any effect since (1) the cost is only used to decide whether
or not to run the exact solver and for this it only matters if it is
zero or not, and (2) the edges of the best group are used correctly.
But it clearly is conceptually wrong.
Use the best group cost, refactor how the information about the best
group is represented, and add debug output which outputs the greedy
solver's overall cost.

[clang-doc] Make CommentInfo arena allocated (#190050)
This patch move the CommentInfo type into the arena. It updates block
handling to collect child info types and serialize the array in one
shot.
We also clean up the test code to avoid using the arenas in the tests.
This has the upside of making the test more hermetic, and avoids churn
in the related code as the allocation API interfaces evolve.
Performance and memory usage regress slightly. This is somewhat expected
as we do not yet aggressively release short term memory during merge
operations. Future patches will reclaim this overhead.

[AMDGPU] Always update SETREG MSBs if offset is 0 (#191362)
We can always update immediate if Offset is zero. The bits
HW will write are always at the same position if offset is 0.
In particular it removes redundant mode changes created as seen
in the hazard-setreg-vgpr-msb-gfx1250.mir.
This still relies on the wrong behavior that SETREG updates
MSBs, so it will have to be changed later. Test immediates may be
off from desired for that reason in this patch.

[CIR] Handle globals with vptr init (#191291)
When a class contains virtual functions but no data members and has a
trivial constructor, global variables of that type are initialized with
a vptr. CIR was incorrectly creating the global variable with the type
of the vtable (an anonymous record) rather than the class type.
When replacing structors with aliases, we were calling a function to
update argument types at the call sites, but this was only necessary
because we initially generated the call using the same incorrect type
that we used for the global. The type correction wasn't implemented
because we hadn't encountered a case where it was needed. Having found
such a case led me to diagnose the problem as above, and I verified that
the same test case compiled without -mconstructor-aliases just failed in
the verifier because we never hit the replacement code. I'm now
convinced that this argument type fixup isn't necessary, so I replaced
the fixup function with an assert.

[WebAssembly] Fix attributes of exception_grouping_2 test (#191466)
Function calls in `exception_grouping_2` test had incorrect attribute
numbers, making many of them incorrectly `noreturn`, rendering many BBs
after them unreachable. As a result of them, the function became a
trivial single-BB and the test passsed because it didn't have any
exceptions in it. I think this happened because I created that test in
another file and later pasted the function into these files, which had
different attribute numbers.
This also has a few drive-by comment typo fixes.

[CIR][ABI] Add ABI metadata fields to RecordType (#188300)
Store AST-derived layout information on `cir::RecordType` so that ABI
lowering passes (which have no AST access) can make correct calling
convention decisions.
The five new fields on `RecordTypeStorage` are: `triviallyCopyable`
(from `canPassInRegisters`), `triviallyDestructible` (from
`hasTrivialDestructor`), `isEmpty` (from
`CXXRecordDecl::isEmpty`/`field_empty`), `dataSizeInBits` (from
`ASTRecordLayout::getDataSize`), and `recordAlignInBytes` (from
`ASTRecordLayout::getAlignment`). They're set during
`computeRecordLayout` and are not part of the printed/parsed CIR text.
The `complete()` signature uses defaults so existing callers don't need
changes.
Anonymous records (created by passes, not CIRGen) default to trivially
copyable/destructible since they represent synthetic aggregates like
member pointer lowering tuples.
Unit test with 9 cases exercises all fields, anonymous defaults, and
backward compatibility.

[MLIR][XeVM] Update XeVM type converter (#189306)
Ideally, DLTI should be used for getting Index type which as it is tied
to bitwidth of pointer type that can be expressed with DLTI.
But currently, a separate pass option for bitwidth of Index type is used
in many passes.
GPU to XeVM lowering pipeline also use passes with such options.
But XeVM type converter does not provide a way to reflect choice of
Index type bitwidth and uses a hardcoded value.
This PR updates XeVM type converter to use Index type bitwidth from pass
option. This is done by using LLVM type converter for converting element
type instead of the previous custom logic.
In addition to handling Index type properly, by using LLVM type
converter, low precision float types are correctly converted to LLVM
supported types.

[RISCV] Remove RISCVCCAssignFn and Simplify (#191071)
I think the signature of `CCAssignFn` has been updated since
`RISCVCCAssignFn` was introduced. There is now enough information passed
that we don't need a separate signature and custom reimplementations to
thread the value through.
We now expose just two `CC_RISCV` functions: one for arguments
(`CC_RISCV`) and one for return values (`RetCC_RISCV`). The argument
version now dispatches to different functions internally depending on
the `CallingConv`.
This allows the backend to remove:
- GISel's custom `RISCVOutgoingValueAssigner` and
`RISCVIncomingValueAssigner`
- GISel's custom implementation of `RISCVCallLowering::canLowerReturn`
- `llvm::RISCVCCAssignFn` which is no longer used.
- SDag's custom `RISCVTargetLowering::analyzeInputArgs` and
`RISCVTargetLowering::analyzeOutputArgs`.
- Code in RISCVISelLowering to choose the right `CC_RISCV` function.
The end result of this is that:
- `ghccc` is now supported with GlobalISel
- `fastcc` should return values correctly with GlobalISel (previously
these were returned using `CC_RISCV_FastCC`, but SelectionDAG only ever
used `CC_RISCV` for return values)
- GlobalISel correctly marks functions as `.variant_cc` (before this
callers that recieved scalable return values were incorrectly marked,
and callees that returned scalable return values were not marked).

[UnitTests] Enable PCH (#191402)
I originally didn't enable PCH for unit tests, because I intended to
build a gtest PCH. But while gtest.h is slow, having many large standard
library headers already pre-compiled via the LLVMSupport PCH already
helps a lot, leaving ~250ms for parsing gtest.h (+ a fair amount of time
for template instantiation). Additionally, for unit tests that include
IR or AST headers, re-using the PCHs that include these is more
beneficial than gtest.h. Therefore, no longer disable PCH on unit tests.

[clang] Improve Ofast Warning (#183002)
`-Ofast` has an effect on the defaults for `-ffast-math` (documented
before this patch), and `-fstrict-aliasing` (not documented before this
patch).
On some platforms, `-Ofast` cannot be replaced with `-O3 -ffast-math`,
because the strict aliasing default would change. `-Ofast` can only be
replaced (in the exact same position) with `-O3 -ffast-math
-fstrict-aliasing` if `-Ofast` is the effective optimization level
(i.e., it is not followed by another `-O<value>` flag). Otherwise, the
`-Ofast` flag should just be deleted as it is having no effect.
This is all too difficult to summarise in a warning message, so this PR
mostly updates the docs. We keep the message about "use `-O3` to get
conforming optimizations" in the hope this encourages people to adopt
`-O3` alone.
The warning message is now emitted any time there is `-Ofast` in the
command-line string, rather than only when `-Ofast` is the effective
optimization level.

[SystemZ][z/OS] Remove use of subsections. (#184167)
HLASM has no notion of subsections. There are several possible solutions
how to deal with this. However,
- using a different section introduces a lot of relocations, which slows
down the binder later
- emitting the PPA1 after the code changes the location which may break
existing tools
The choosen solution is to record the PPA1 data, and emit them at the
end of the assembly into the code section. This solves both issues, at
the expense of having to do some bookkeeping.
This change moves the position of the PPA2, too, but this is less
critical.

Reverting both on LoongArch and RISC-V as the implementations are
identical and one of the fix commits touches both targets, rather than
doing only a RISC-V revert. I also think this more cleanly shows what is
being undone when starting again with the changes.

change in logic now, which should make later refactoring much more

[Offload] Fix inefficient GNU Hash ELF symbol lookup (#191477)
Summary:
This PR fixes the handling of the GNU Hash table. The chain format uses
the lowest bit to indicate the end of the list. Previously we just
continued the loop instead of breaking, meaning we would exhaustively
search the whole list if the symbol was not found instead of just early
existing. This was still correct and worked in practice, but it was
slightly inefficient. Likely not noticed because the symbol tables on
these GPU binaries tend to be relatively small.

a single error string appended to the main diagnostic. Information that

reported as notes (e.g. signature mismatches)
This patch additionally
* Adds minor comments to places I found unintuitive
* Adds a contrived test case for signature mismatches
* Sets `InputFilesValidation` based on module kind at construction

[cmake] Add support for statically linking libxml2 (#166867)
Dynamically depending on libxml2 results in various annoyances across
different linux distros for release artifacts. Specifically on fedora
and nixos the library has a different name than on debian, and on
arch-linux they tried to remove the old name entirely.
With this, enabled by default for releases, we don't sacrifice any
behavior changes, but no longer have these issues. For lld the binary
size impact is <1mb
This continues to use the shared libxml for lldb since otherwise
it requires linking ICU, which is off by default
macOS ignores this setting since libxml2 is part of the OS and stable
enough.
This mirrors what we do for zstd

[clang-doc] Move Info types into arenas (#190054)
Info types used to own significant chunks of data. As we move these into
local arenas, these types must be trivially destructible, to avoid
leaking resources when the arena is reset. Unfortunatly, there isn't a
good way to transition all the data types one at a time, since most of
them are tied together in some way. Further, as they're now allocated in
the arenas, they often cannot be treated the same way, and even the
aliases and interfaces put in place to simplify the transition cannot
cover the full range of changes required.
We also use some SFINAE tricks to avoid adding boilerplate for helper
APIs, we'd otherwise have to support
Though it introduces some additional churn, we also try to keep tests
from using arena allocation as much as possible, since this is not
required to test the implementation of the library. As much of the test
code needed to be rewritten anyway, we take the opportunity to
transition now.
We see a large improvement in overall memory use, dropping by 15% over
the previous patches, and taking the total savings down to almost 54%.
Performance numbers stay mostly flat, but merging is vastly improved,
seeing a reduction of 40+% over the previous patch, and a 90% reduction
overall.

[AMDGPU] Use WriteSALUDummy for v_mad_u64_u32 (#191500)
Updates the the new Write*Dummy HWWriteRes to maintain latency -- this
is to ensure SchedModel->computeOperandLatency calls are unchanged.
This also uses the new HWWriteRes for v_mad_u64_u32 and v_mad_i64_i32.
For an explanation of why we want to do this , see
https://github.com/llvm/llvm-project/pull/190095 . In short, the
scheduler will not try to cover the full latency of the instructions
without this new modelling.
This causes a good amount of lit churn since these instructions are well
covered.

[clang-doc] Support deep copy between arenas for merging (#190055)
Upcoming changes to the merge step will necessitate that we clear the
transient arenas and merge new items into the persistent arena. However
there are some challenges with that, as the existing types typically
don't want to be copied. We introduce some new APIs to simplify that
task and ensure we don't accidentally leak memory.
On the performance front, we reclaim about 2% of the overhead, bringing
the cumulative overhead from the series of patches down to about 7% over
the baseline.

[clang-doc] Merge data into persistent memory (#190056)
We have a need for persistent memory for the final info. Since each
group processes a single USR at a time, every USR is only ever processed
by a single thread from the thread pool. This means that we can keep per
thread persistent storage for all the info. There is significant
duplicated data between all the serialized records, so we can just merge
the final/unique items into the persistent arena, and clear out the
scratch/transient arena as we process each record in the bitcode.
The patch adds some APIs to help with managing the data, merging, and
allocation of data in the correct arena. It also safely merges and deep
copies data from the transient arenas into persistent storage that is
never reset until the program completes.
This patch reduces memory by another % over the previous patches,
bringing the total savings over the baseline to 57%. Runtime performance
and benchmarks stay mostly flat with modest improvements.

[Codegen, X86] Add prefetch insertion based on Propeller profile (#166324)
This PR implements the prefetch insertion in the InsertCodePrefetch pass
based on the
[RFC](https://discourse.llvm.org/t/rfc-code-prefetch-insertion/88668).
If the prefetch target is not defined in the same module (i.e, prefetch
target function is not defined in the same module), we emit a fallback
weak symbol after the prefetch instruction so that if the symbol is not
ever defined, we don't get undefined symbol error and the prefetch
instruction prefetches the next address:
```
prefetchit1 __llvm_prefetch_target_foo(%rip)
.weak __llvm_prefetch_target_foo
__llvm_prefetch_target_foo:
```
The weak symbol semantic is tied to ELF, so this makes this PR
target-dependent.

[mlir][sparse][gpu] fix sparse GPU codegen out buffer (#189221)
When lowering sparse tensor operations to GPU code using
`-sparse-gpu-codegen`, the generated `gpu.memcpy` op for device-to-host
copy was targeting the wrong buffer. In my case, it did not copy back
the output buffer and instead only copied back the input positions
buffer which results in the output buffer in host memory being empty.
The `SparseGPUCodegen` pass carries an assumption that the first buffer
is the out buffer. It looks like this assumption is not always true, as
in my case its the input positions buffer which made it the only buffer
getting copied back to host.
This change introduces a fix by removing the assumption and replacing it
with an analysis that checks for `memref::StoreOp` and write
MemoryEffects. This change also adds a regression test which highlights
the problematic edge case.
Assisted by Gemini 3.1 Pro for finding the issue of using incorrect
buffers in `gpu.memcpy` op in the lowered code.

[flang][CUF] Limit Flang LICM for operations with symbol operands. (#191494)
There is probably an ordering issue between `CUFDeviceGlobal`
and `OffloadLiveInValueCanonicalization` passes: Flang LICM hoists
`fir.address_of` out of `cuf.kernel`, it is pulled back by
`OffloadLiveInValueCanonicalization`, but the symbol is never added
into the device module because `CUFDeviceGlobal` does not run after.
Changing the passes order may take some time, so this is a temporary
workaround to unblock #191309.
The change is currently NFC.

[MC,CodeGen] Update .prefalign for symbol-based preferred alignment (#184032)
https://discourse.llvm.org/t/rfc-enhancing-function-alignment-attributes/88019/17
The recently-introduced .prefalign only worked when each function was in
its own section (-ffunction-sections), because the section size gave the
function body size needed for the alignment rule.
This led to -ffunction-sections and -fno-function-sections AsmPrinter
differences (#155529), which is rather unusual.
This patch fixes this AsmPrinter difference by extending .prefalign to
accept an end symbol and a required fill operand:
.prefalign <log2_align>, <end_sym>, nop
.prefalign <log2_align>, <end_sym>, <fill_byte>
The first operand is a log2 alignment value (e.g. 4 means 16-byte
alignment). The body size (end_sym_offset - start_offset) determines the
alignment:
body_size < pref_align => ComputedAlign = std::bit_ceil(body_size)
body_size >= pref_align => ComputedAlign = pref_align
To also enforce a minimum alignment, emit a .p2align before .prefalign.
The fill operand is required: `nop` generates target-appropriate NOP
instructions via writeNopData, while an integer in [0,255] fills the
padding with that byte value.
Initialize MCSection::CurFragList to nullptr and add a null check
to skip ELFObjectWriter-created sections like .strtab/.symtab
that never receive changeSection calls.
relaxPrefAlign is called in both layoutSection and relaxFragment.
The layoutSection call ensures correct initial padding before
relaxOnce, and is also needed for the post-finishLayout re-layout
where relaxOnce is not used. relaxPrefAlign walks forward to the
end symbol to compute BodySize (summing fragment sizes), avoiding
dependence on stale downstream symbol offsets.

---
A little (unfortunate) winding history, mostly for my mental bookeeping.
Read the below only if you are curious:
There is a function called `findUnwindDestinations` in
`SelectionDAGBuilder.cpp`.
https://github.com/llvm/llvm-project/blob/c94f79886035a61bb5f3dc992f75fe0c08bdcd4b/llvm/lib/CodeGen/SelectionDAG/SelectionDAGBuilder.cpp#L2107-L2164
This function adds unwind successors to BBs with `invoke`s. In case of
Itanium EH, you only add one `landingpad` BB. In WinEH, `catchswitch`
may not catch an exception, so you add all possible unwind
destionations. For example,
```ll
entry:
invoke void @foo()
to label %try.cont unwind label %catch.dispatch
catch.dispatch:
%0 = catchswitch within none [label %catch.start] unwind label %catch.dispatch1
catch.start:
...
catch.dispatch1:
%7 = catchswitch within none [label %catch.start1] unwind to caller
catch.start1:
...
```
`catchswitch` BBs are removed in iSel. So in this case, both
`catch.start` and `catch.start1` BBs are added as unwind successors to
`entry`, because an exception may not be caught by `catch.dispatch` and
unwind further to `catch.dispatch1`.
In the beginning of 2019, I added our own `findWasmUnwindDestinations`
in
https://github.com/llvm/llvm-project/commit/d6f487863dc951d467b545b86b9ea62980569b5a.
This was when I was implementing [the V2 (pre-legacy)
proposal,](https://github.com/WebAssembly/exception-handling/blob/main/proposals/exception-handling/pre-legacy/Exceptions-v2.md)
which had `exnref` and `try`-`catch_all` (It was named `catch`, but
semantically it was `catch_all`) The rationale was, even though we were
using WinEH, we only had one catchpad and `catch` caught everything. So
I figured adding only the first catchpad successor, `catch.start` in the
example above, would simpify things.
By the end of 2020, we changed the proposal to [the V3 (legacy)
proposal](https://github.com/WebAssembly/exception-handling/blob/main/proposals/exception-handling/legacy/Exceptions.md),
which removed `exnref` and introduced separate `catch` and `catch_all`
instructions. The previous invariant "`catch` always catches everything"
didn't hold anymore, but I left `findWasmUnwindDestinations` as was with
some updated comments in
https://github.com/llvm/llvm-project/commit/9e4eadeb135d140b3a9e499354472170017cbe58.
The comments could be summed up as "there will always be an `invoke`
instruction in the first catchpad that unwinds to the next unwind
destination. (which later turned out to be false)
And in 2021, I tweaked the ExceptionInfo algorithm to fix exception
grouping
(https://github.com/llvm/llvm-project/commit/ea8c6375e3330f181105106b3adb84ff9fa76a7c,
https://github.com/llvm/llvm-project/commit/4a58116b7e5e1439c5fefdf59a89fc4f1d42875c,
and
https://github.com/llvm/llvm-project/commit/2b957ed4ff3344d8f761a053566e307277a1cdeb)
The bug was, in tl;dr: "Your next unwind destination can be
(accidentally) dominated by your current catchpad, making your unwind
destination a subexception of the current exception). For example:
```cpp
try {
try {
foo();
} catch (int) { // EH pad
...
}
} catch (...) { // unwind destination
}
```
Here the outer `catch` is (accidentally) dominated by the inner `catch`,
because we only added the first catchpad (inner `catch`) as an unwind
successor of `foo()` BB, and hoped that some `invoke`s within the inner
`catch` to unwind it to the outer `catch`. But this caused us to
`delegate` to a middle of an inner scope. So I tweaked the algorithm to
take the outer `catch` out to form a separate exception. I didn't
realize `findWasmUnwindDestinations` was actually the source of problem
then.
Fast forward to 2025. The 2020 assumption of "There will always be an
`invoke` instruction in the first catchpad" turned out to be false. So I
just removed `findWasmUnwindDestinations` and switched to use the common
`findUnwindDestinations` in #130374, which recently accidentally
discovered another bug (#187302).
While investigating #187302, I realized we don't need those tweaks in
WebAssemblyExceptionInfo anymore, because `findUnwindDestinations` adds
all unwind destinations as successors. (#187302 is actually not related
to this; it was just a trigger to investigate things) So in case of the
little C++ example above, the outer `catch` BB will also be added as an
unwind successor of the `foo()` BB. I actually think we may not even
need WebAssemblyExceptionInfo analysis at all if we only use [the latest
standard (exnref)
proposal](https://github.com/WebAssembly/exception-handling/blob/main/proposals/exception-handling/Exceptions.md).
But we still need to keep the legacy support, so we need it for now.

`mai-insts` feature, which is incorrect (`gfx908` supports this and does
not support the added MFMAs). This led to opaque bugs where we'd check
with `__has_builtin` for the availability of the builtin, target 908,
and get an ISEL failure.

[SLP] Fix CmpInst type handling in cost model
Previously, getValueType() always returned the compared operand type
(e.g. i32) for CmpInst, which was incorrect for gather cost estimation
and codegen where the result type (i1) is needed. This caused ad-hoc
fixups scattered across getEntryCost, calculateTreeCostAndTrimNonProfitable,
and vectorizeTree that overrode ScalarTy back to i1 for CmpInsts.
Add a LookThroughCmp parameter to getValueType() (default: false) so
callers that need the operand type for vector width calculations can
explicitly opt in. This removes the need for the scattered CmpInst
special cases:
- getEntryCost gather path: remove `if (isa<CmpInst>) ScalarTy = i1`
- calculateTreeCostAndTrimNonProfitable: remove same override
- vectorizeTree: simplify `if (!isa<CmpInst>) ScalarTy = getValueType(V)`
to just `getValueType(V)`
For the ICmp/FCmp cost case in getEntryCost, add a fallthrough from
ICmp/FCmp to Select that overrides ScalarTy with the compared operand
type via getValueType(VL0, true), since getCmpSelInstrCost expects the
compared type as its first argument. Fix the condition type argument
passed to getCmpSelInstrCost for both scalar and vector paths: use the
actual condition/result type instead of always Builder.getInt1Ty().

[SLP] Reject 2-element vectorization when vector inst count exceeds scalar
The LLVM cost model uses integer-valued throughput costs which cannot
represent fractional costs. For 2-element vectors, this rounding can
make vectorization appear profitable when it actually produces more
instructions than the scalar code — the overhead from shuffles, inserts,
extracts, and buildvectors is underestimated.
Add an instruction-count safety check in getTreeCost that estimates
the number of vector instructions (including gathers, shuffles, and
extracts) and compares against the number of scalar instructions.
If the vector code would produce more instructions, reject the tree
regardless of what the cost model says. This catches cases where
fractional cost rounding hides real overhead.
The check is gated behind -slp-inst-count-check (default: on) and
only applies to 2-element root trees where rounding errors matter most.

[SLP][REVEC] Fix InsertElement scalar type in getEntryCost
When SLPReVec is enabled, getValueType returns the vector result type
for InsertElement instructions rather than the scalar element type. This
caused getEntryCost to propagate an incorrect ScalarTy (e.g. <4 x float>
instead of float) into getScalarizationOverhead and getWidenedType,
triggering an assertion failure and producing wrong cost estimates.
Narrow ScalarTy to its element type when costing vectorized
InsertElement entries whose inserted operands are scalars.

[AMDGPU][Scheduler] Prepare remat stage for rematerializer integration (NFC) (#189489)
This NFC prepares the scheduler's rematerialization stage for
integration with the target-independent rematerializer. It brings
various small design changes and optimizations to the stage's internal
state to make the not-exactly-NFC rematerializer integration as small as
possible.
The main changes are, in no particular order:
- Sort and pick useful rematerialization candidates by their index in
the vector of candidates instead of directly sorting objects within the
candidate vector. This reduces the amount of data movement and
simplifies the candidate selection logic.
- Move some data members from `PreRARematStage::RematReg` to
`PreRARematStage::ScoredRemat`. This makes the former a simplified
version of the rematerializer's own internal register representation
(`Rematerializer::Reg`), which can be cleanly deleted during
integration.
- Remove an inferable argument to `modifyRegionSchedule`. This allows
the stage to stop tracking the parent block of each region.
- Use a boolean (`RevertAllRegions`) to track scheduling revert decision
post rematerialization instead of clearing `RescheduleRegions`. This
allows to avoid re-computing the latter during rollback.
- Estimate usefulness of rematerialization from `GCNRegPressure` instead
of from `Register` (requires adding a new method variant in
`GCNRPTarget`).

[lldb][Platform] Use the module's FileSpec instead of the script's FileSpec when checking LoadScriptFromSymFile setting (#191473)
We were incorrectly passing the script's `FileSpec` into
`GetScriptLoadStyleForModule`. Meaning if a script name wasn't actually
the same as the module name, the `target.auto-load-scripts-for-modules`
didn't take effect.
This patch passes the module's `FileSpec` instead. For `dSYM`s we save
the original `FileSpec` because the loop tries to strip extensions until
it finds a script. But we still want to use the module's name.

[Clang] Track constraint's SubstIndex only if it contains outer parameter packs (#191484)
I believe that is the intent of SubstIndex in AssociatedConstraint.
So this enforces the checking explicitly, in case nested SubstIndexes
confuses our poor constraint evaluator.
I reverted the previous fix 257cc5ad89840cdfba4affcc8fe62cf9d02d9017
because that was wrong.
As a drive-by fix, this also removes an strange assertion and an
unnecessary
SubstIndex setup in nested requirement transform.
No release note because this is a regression fix.

[AsmPrinter] Use AsmPrinterAnalysis to hold AsmPrinter
AsmPrinter needs to hold state between doInitialization,
runOnMachineFunction, and doFinalization, which are all separate passes
in the NewPM. Storing this state externally somewhere like
MachineModuleInfo or a new analysis is possible, but a bit messy given
some state, particularly EHHandler objects, has backreferences into the
AsmPrinter and assumes there is a single AsmPrinter throughout the
entire compilation. So instead, store AsmPrinter in an analysis that
stays constant throughout compilation which solves all these problems.
This also means we can also just let AsmPrinter continue to own the
MCStreamer, which means object file emission should work after this as
well.
This does require passing the ModuleAnalysisManager into
buildCodeGenPipeline to register the AsmPrinterAnalysis, but that seems
pretty reasonable to do.

[AMDGPU] Use value's DebugLoc for bitcast in performStoreCombine (#186766)
## Description
When `AMDGPUTargetLowering::performStoreCombine` inserts a synthetic
bitcast to convert vector types (e.g. `<1 x float>` → `i32`) for stores,
the bitcast inherits the **store's** SDLoc. When
`DAGCombiner::visitBITCAST` later folds `bitcast(load)` → `load`, the
resulting load loses its original debug location.
## Analysis
The bitcast is **not** present in the initial SelectionDAG — it is
inserted during DAGCombine by
`AMDGPUTargetLowering::performStoreCombine`. This can be observed with
`-debug-only=isel,dagcombine`:
```
Initial selection DAG: no bitcast, load is v1f32 directly used by store
Combining: t17: ch = store ... /tmp/beans.c:6:14
... into: t20: ch = store ... /tmp/beans.c:6:14
Combining: t19: i32 = bitcast [ORD=3] # D:1 t13, /tmp/beans.c:6:14
... into: t21: i32,ch = load ... /tmp/beans.c:6:14
```
In `performStoreCombine` (`AMDGPUISelLowering.cpp`):
```cpp
SDLoc SL(N); // N = store node → SL has store's DebugLoc
...
SDValue CastVal = DAG.getNode(ISD::BITCAST, SL, NewVT, Val);
// bitcast gets store's DebugLoc, not load's
```
When `visitBITCAST` folds `bitcast(load)` → `load`, it uses `SDLoc(N)`
(the bitcast's loc = store's loc), so the resulting load loses its
original debug location.
```
Before (initial DAG):
t13: v1f32 = load ... line 2 ; original load
t14: ch = store t13, ... line 3 ; store
After performStoreCombine:
t13: v1f32 = load ... line 2 ; original load
t19: i32 = bitcast t13 line 3 ; synthetic bitcast (store's loc!)
t20: ch = store t19, ... line 3
After visitBITCAST folds (incorrect):
t21: i32 = load ... line 0 ; lost debug location
After visitBITCAST folds (expected):
t21: i32 = load ... line 2 ; preserves load's location
```
## Fix
Target-specific fix in `AMDGPUISelLowering.cpp` `performStoreCombine`:
use `DAG.getBitcast()` instead of `DAG.getNode(ISD::BITCAST, SL, ...)`.
`getBitcast()` internally uses `SDLoc(V)` (the value operand's SDLoc),
so the synthetic bitcast naturally inherits the load's DebugLoc instead
of the store's:
```cpp
// Before:
SDValue CastVal = DAG.getNode(ISD::BITCAST, SL, NewVT, Val);
if (OtherUses) {
SDValue CastBack = DAG.getNode(ISD::BITCAST, SL, VT, CastVal);
// After:
SDValue CastVal = DAG.getBitcast(NewVT, Val);
if (OtherUses) {
SDValue CastBack = DAG.getBitcast(VT, CastVal);
```
This is consistent with `performLoadCombine` where the bitcast also uses
the load's `SDLoc`.

[AMDGPU][Scheduler] Use MIR-level rematerializer in rematerialization stage (#189491)
This makes the scheduler's rematerialization stage use the
target-independent rematerializer. Previously duplicate logic is
deleted, and restrictions are put in place in the stage so that the same
constraints as before apply on rematerializable registers (as the
rematerializer is able to expose many more rematerialization
opportunities than what the stage can track at the moment). Consequently
it is not expected that this change improves performance overall, but it
is a first step toward being able to use the rematerializer's more
advanced capabilities during scheduling.
This is *not* a NFC for 2 reasons.
- Score equalities between two rematerialization candidates with
otherwise equivalent score are decided by their corresponding register's
index handle in the rematerializer (previously the pointer to their
state object's value). This is determined by the rematerializer's
register collection order, which is different from the stage's old
register collection order. This is the cause of all test changes but
one, and should not be detrimental to performance in real cases.
- To support rollback, the stage now uses the rematerializer's rollback
listener instead of its previous ad-hoc method (setting the opcode of
rematerialized MIs to a DBG_VALUE, and their registers to the sentinel).
This is the source of test changes in
`machine-scheduler-sink-trivial-remats-debug.mir`. The new rollback
mechanism completely removes the behavior tested by
`misched-remat-revert.ll` so the test is deleted.

[SLP] Fix GEP cost computation for load vectorization cost estimates
Pass Instruction::Load instead of Instruction::GetElementPtr to
getGEPCosts in isMaskedLoadCompress and CheckForShuffledLoads.
These call sites estimate costs for wide contiguous loads and sub-vector
load patterns, not for masked gather pointer vector formation. Using
Instruction::GetElementPtr incorrectly triggered the gather-style cost
path, which computes vector GEP formation costs. Since the call sites
already add scalarization overhead for pointer vector building
separately, this led to double-counting of pointer costs and inaccurate
vectorization decisions.

[clang][bytecode] Support different integral types (e.g. addresses) (#185028)
This is an alternative approach to
https://github.com/llvm/llvm-project/pull/169769.
We increase the size of the old `Integral<Bits, Signed>` to 24 bytes (on
a 64 bit system) and introduce a new `Char<Signed>` that's used for the
old `PT_Sint8` and `PT_Uint8` primitive types.
The old approach did not work out in the end because we need to be able
to do arithmetic (but essentially just `+` and `-`) on the offsets of
such integers-that-are-actually-pointers.

When a value is treated as a copyable element in one tree entry and as a

scheduler could produce vectorized IR where an instruction does not
dominate all its uses. Bail out of scheduling in tryScheduleBundle when
this conflict is detected to prevent generating broken modules.

unnecessary coupling between ExecutorProcessControl and MemoryAccess,
allowing clients to select MemoryAccess implementations independently.
To simplify the transition, the
ExecutorProcessControl::createDefaultMemoryAccess method will return an
instance of whatever MemoryAccess the ExecutorProcessControl
implementation had been using previously.

[AsmPrinter] Fix redundant/weaker .prefalign when IR align attr >= prefalign (#191675)
PR #155529 (only fired with -ffunction-sections, then modified by PR
184032) compared `MF->getAlignment()` (the backend's minimum function
alignment) against `MF->getPreferredAlignment()` to decide whether to
emit `.prefalign`. This ignored the IR function's own align attribute,
which `emitAlignment` picks up later via `getGVAlignment`, so the
comparison was against the wrong minimum.
Consequences on x86 (backend min = 1, target pref = 16):
* `[[gnu::aligned(32)]] void g(){}` lowers to `align 32 prefalign(32)`.
.p2align 5
.prefalign 5, .Lfunc_end, nop
The .prefalign is fully redundant: .p2align 5 already forces the
desired 32-byte alignment.
* `define void @f4() align 32 prefalign(16)`.
.p2align 5
.prefalign 4, .Lfunc_end, nop
Here .prefalign with a weak alignment is harmless but the assembly
output is nonsensical.
This patch updates `emitAlignment` to return the effective alignment it
emits and use that as the true minimum in `emitFunctionHeader`.

Fix 136-byte memory leak introduced in commit 6dc059ac3c7c. Before
that commit, the TextDiagnosticBuffer was passed to DiagnosticsEngine
constructor which took ownership and managed its lifetime. After the
refactoring, the buffer is no longer passed to DiagnosticsEngine, so
it becomes an orphaned allocation that is never freed. Changed to use
std::unique_ptr for automatic cleanup.

[LLVM][Intrinsics] Eliminate range check for IIT table in `DecodeIITType` (#190260)
`DecodeIITType` does a range check each time the next entry from the IIT
encoding table is read. This is required to handle IIT encodings that
are in-lined into the `IIT_Table` entries, since the `IITEntries` array
in `getIntrinsicInfoTableEntries` is terminated after the last non-zero
nibble is seen in the inlined encoding (but that may not be the actual
end). Change this code to instead have the `IITEntries` array for the
inlined case point to the full `IITValues` array payload + a IIT_Done
terminator, so that such entries look exactly like they would if they
were encoded in the long encoding table and then remove the range check
in `DecodeIITType` to streamline that code a bit.
Additionally, change some use if 0s (in loop conditions and default
constructed terminator in the IIT long encoding table) to explicitly use
IIT_Done to clarify the code better.
Also use `consume_front()` in a few places instead of `front()` followed
by `slice(1)`.

[libclc] Enable LLVM_RUNTIME_TARGETS in build system (#189892)
libclc target is now passed in from LLVM_RUNTIME_TARGETS.
The old configure flow based on `-DLLVM_ENABLE_RUNTIMES=libclc` is
deprecated because libclc no longer has a default target.
`-DLLVM_ENABLE_RUNTIMES=libclc -DLLVM_RUNTIME_TARGETS="<target-triple>"`
still works but it is considered legacy.
The new standard build requires:
Each target must now be selected explicitly on the CMake command line
through the runtimes target-specific cache entry and
LLVM_RUNTIME_TARGETS.
For example:
-DRUNTIMES_amdgcn-amd-amdhsa-llvm_LLVM_ENABLE_RUNTIMES=libclc
-DLLVM_RUNTIME_TARGETS="amdgcn-amd-amdhsa-llvm"
-DRUNTIMES_nvptx64-nvidia-cuda_LLVM_ENABLE_RUNTIMES=libclc
-DLLVM_RUNTIME_TARGETS="nvptx64-nvidia-cuda"
-DRUNTIMES_clspv--_LLVM_ENABLE_RUNTIMES=libclc
-DLLVM_RUNTIME_TARGETS="clspv--"
-DRUNTIMES_clspv64--_LLVM_ENABLE_RUNTIMES=libclc
-DLLVM_RUNTIME_TARGETS="clspv64--"
-DRUNTIMES_spirv-mesa3d-_LLVM_ENABLE_RUNTIMES=libclc
-DLLVM_RUNTIME_TARGETS="spirv-mesa3d-"
-DRUNTIMES_spirv64-mesa3d-_LLVM_ENABLE_RUNTIMES=libclc
-DLLVM_RUNTIME_TARGETS="spirv64-mesa3d-"
To build multiple targets, pass them as a semicolon-separated list in
`LLVM_RUNTIME_TARGETS` and provide a matching
`RUNTIMES_<target-triple>_LLVM_ENABLE_RUNTIMES=libclc` entry for each
target.
Updated README.md to document the new build flow.

[AArch64] Skip non-pseudo instructions in AArch64ExpandPseudoInsts (#191395)
AArch64::getSVEPseudoMap calls are visible in compile-time profiles even on
non-SVE targets. I think CodeGenMapTable could be improved, it's currently
emitting a constexpr array sorted by opcode and a hand-rolled binary search
over that array, however the AArch64ExpandPseudoInsts pass is missing a simple
check for pseudo instructions before expanding. This avoids the compile-time
cost.

[analyzer] Refine default binding preservation in RegionStore (#189319)
Narrow the new setImplicitDefaultValue() guard so existing default
bindings are preserved only for aggregate-like cases.
The previous change was too broad and regressed normal
zero-initialization, causing new int[10]{} to be modeled as undefined
and emit a garbage-value warning instead of the expected analyzer
reports.

[MISched] Extract `isClustered()` method on SUnit (NFC) (#191700)
This patch encapsulates the check for wether a `SUnit` is clustered,
rather than letting it scatter across call sites. Currently there is
only a single user, but more users can show up, and I think it provides
a cleaner API even for that single user.

DAG lowering for the SME ABI.

(`-aarch64-new-sme-abi=true`).

[MLIR][MemRef] Fix DimOfReifyRankedShapedTypeOpInterface IR-change on failure (#188973)
DimOfReifyRankedShapedTypeOpInterface::matchAndRewrite called
reifyDimOfResult via the PatternRewriter. Some implementations delegate
to the coarse-grained reifyResultShapes, which creates ops for ALL
dimensions (e.g. a tensor.dim) before discovering that a specific
dimension is not reifiable (signalled by an empty OpFoldResult).
The pattern then returned failure() once it saw the empty OpFoldResult,
but the newly created ops were already in the IR. Under
MLIR_ENABLE_EXPENSIVE_PATTERN_API_CHECKS this triggered "pattern
returned failure but IR did change".
Fix: record the op immediately before the matched dim op, so we can
identify ops inserted during the reification attempt. If reification
returns an empty (unreifiable) OpFoldResult, erase those newly created
ops before returning failure, restoring the IR to its original state.

[OpenACC] Fix pattern API check failures in acc-loop-tiling pass (#188968)
Two bugs were introduced/revealed by
MLIR_ENABLE_EXPENSIVE_PATTERN_API_CHECKS:
1. `ACCLoopTilingImpl::matchAndRewrite` returned `success()` for loops
with no tile values, triggering "pattern returned success but IR did not
change". Fixed by returning `failure()` instead.
2. `moveOpsAndReplaceIVs` moved ops between blocks via `splice()` and
updated operands via `replaceAllUsesInRegionWith()` without notifying
the rewriter. This caused "operation fingerprint changed" errors since
the moved ops' parent op and operands changed without
`startOpModification`/ `finalizeOpModification`. Fixed by wrapping all
moved ops (and their nested ops) with rewriter modification
notifications.

the SPIR-V spec Decoration table, but this was not deduced.
Add an explicit check in UpdateVCEPass: when a `spirv.GlobalVariable`
has a `binding` or `descriptor_set` attribute, require the `Shader`
capability.

[compiler-rt] clang-cl: skip MSVC external-header probe; -std=c++ for unit-test compiles (#191564)
1. `check_cxx_compiler_flag` marked `COMPILER_RT_HAS_EXTERNAL_FLAG` true
for clang-cl, so `/experimental:external` and `/external:anglebrackets`
were passed and clang-cl warned they were unused. Now only probe with
real MSVC (not Clang); set the flag false otherwise; rely on that in
asan/interception/ubsan.
2. Custom compile lines for unit tests didn’t get C++17, so headers hit
`-Wc++17-extensions` (e.g. `constexpr if` / message-less `static_assert`
in FuzzedDataProvider / asan_fake_stack). Now append
`-std=c++${CMAKE_CXX_STANDARD}` or `-std=c++17` for C++ sources in
`clang_compile()` for both standalone and non-standalone builds.

[MLIR][ODS] Error on optional attribute used outside optional group in assemblyFormat (#188726)
Using an optional attribute directly in assemblyFormat (e.g., `$attr
attr-dict`) without wrapping it in an optional group causes the
generated printer to call `printAttribute` with a null `Attribute` when
the attribute is absent. This leads to a crash in the alias initializer
when it calls `getAlias` on a null attribute.
Add a validation check in `OpFormatParser::verifyAttributes` that
detects this pattern and emits a diagnostic error with a helpful note
pointing users to the correct `($attr^)?` syntax.
Fixes #58064

[lldb] Add binary multiplication, division, remainder to DIL (#187281)
Add binary arithmetic multiplication, division, remainder to DIL.
This patch also passes DILMode to the parser to check if binary
multiplication is allowed by the mode. This cannot be done in the lexer
alone, because it allows token `*` as a dereference operator for legacy
mode, but that token could also be a binary multiplication allowed only
in full mode.

[MLIR][LLVMIR] Handle MDTuple-of-MDStrings module flags (e.g. riscv-isa) (#188741)
The "riscv-isa" LLVM module flag stores its value as an MDTuple
containing MDStrings (e.g. `\!{\!"rv64i2p1", \!"m2p0"}`). Previously,
this fell through the unrecognized-key path in
`convertModuleFlagValueFromMDTuple`, which emitted a warning and dropped
the flag during import.
This patch adds generic handling for MDTuples whose operands are all
MDStrings:
- Import: convert to `ArrayAttr<StringAttr>` in
`convertModuleFlagValueFromMDTuple`
- Export: convert `ArrayAttr<StringAttr>` back to an MDTuple of
MDStrings in `convertModuleFlagValue`, enabling a lossless round-trip
- Verifier: allow `ArrayAttr<StringAttr>` as a valid `ModuleFlagAttr`
value for keys not otherwise handled by specific verifier branches

common logic has been extracted to a new internal function which both
now call.
In addition to the function definition, the patch adds a unit test and a
fuzzing test.

[AArch64] Mark X16 as clobbered in PAUTH_EPILOGUE for hint-based PAuthLR (#175991)
When users request branch protection with PAuthLR on targets that do not
support the PAuthLR instructions, the PAUTH_EPILOGUE falls back to using
hint-space instructions. This fallback sequence uses X16 as a temporary
register, but X16 was not listed in the clobber set.
Because Speculative Load Hardening uses X16, this omission made SLH
incompatible with this PAUTH_EPILOGUE path.
Mark X16 as clobbered so the compiler does not assume X16 is preserved
across the epilogue, restoring compatibility with Speculative Load
Hardening and avoiding incorrect register liveness assumptions. The
clobber is added in C++ rather than TableGen, as X16 is only clobbered
when PAuthLR is requested as a branch protection variation and should
not be treated as clobbered unconditionally.

[SPIR-V] Fix type mismatch in scalar-to-vector promotion for mixed-type builtins (#190969)
When promoting scalar arguments to vectors for builtins like `ldexp`,
`pown`, and `rootn`, use the correct vector type matching the argument
element type instead of always using the return type: these builtins
take an integer argument but at the same time have floating point return
type
Fix `ldexp` test that does not pass spirv-val and add similar tests for
`pown` and `rootn`

[Support] Remove address-extraction methods from DataExtractor (NFC) (#190519)
Most clients don't have a notion of "address" and pass arbitrary values
(including `0` and `sizeof(void *)`) to `DataExtractor` constructors.
This makes address-extraction methods dangerous to use.
Those clients that do have a notion of address can use other methods
like `getUnsigned()` to extract an address, or they can derive from
`DataExtractor` and add convenience methods if extracting an address is
routine. `DWARFDataExtractor` is an example, where the removed methods
were actually moved.
This does not remove `AddressSize` argument of `DataExtractor`
constructors yet, but makes it unused and overloads constructors in
preparation for their deletion. I'll be removing uses of the
to-be-deleted constructors in follow-up patches.

Replace the manual check in `verifyRemoved()` with `AssertingVH`

this is a cheaper way to verify we don't have dangling entries in the
leader table.
For this change, we must implement a move constructor for `AssertingVH`
so that we can keep the first entry as an inline-allocated node that
will be handled correctly as the table grows.

[RISCV] Expand vp.fma, fp.fmuladd, vp.fneg, vp.fpext (#190589)
Part of the work to remove trivial VP intrinsics from the RISC-V
backend, see
https://discourse.llvm.org/t/rfc-remove-codegen-support-for-trivial-vp-intrinsics-in-the-risc-v-backend/87999
This PR expands four intrinsics before codegen, but doesn't remove the
codegen handling yet as both DAGCombiner and type legalization can
create these nodes.
vp.fneg and vp.fpext are expanded in lockstep with the fma/fmuladd
intrinsics since some test cases for vfmacc etc. also use these
intrinsics, and mixing dynamic and constant vls causes some of the more
complex patterns to be missed.
The fixed-length VP vfmacc, vfmsac, vfnmacc and vfnmsac tests also need
to replace the EVL of the vp.merge/vp.select with an immediate otherwise
the resulting vmerge.vvm can't be folded into them. This only happens
for fixed vector intrinsics with no passthru, since we end up with a
constant vl from the fixed vector and dynamic vl from the vp.merge that
prevents folding.
As far as I'm aware we don't emit fixed length vp.merges in practice,
since we only emit vp.merge in the loop vectorizer, and we only use it
with EVL tail folding which requires a scalable VF.

This change aims to make it easier for MachOPlatform clients to
customize JITDylib MachO headers.
At MachOPlatform construction time clients can now supply a
MachOPlatform::HeaderOptionsBuilder. The supplied callback will be
called by setupJITDylib to create the HeaderOptions for the JITDylib
being set up.
No testcase: Constructing a MachOPlatform instance requires the ORC
runtime, which we can't require for LLVM unit or regression suite tests.
We should look at testing this functionality in the new ORC runtime once
it's ready.

[AArch64][llvm] Add GICv5 ICH_PPI_HVIR{0,1}_EL2 system registers (#191818)
Add GICv5 `ICH_PPI_HVIR{0,1}_EL2` system registers (Interrupt
Controller PPI Hide Virtual Interrupt Registers). These registers
are added because a hypervisor may want to only expose a subset of the
PPIs to the virtual machine and hide the remaining PPIs.
The only way the hypervisor can do this is by trapping all the PPI ICV
registers which leads to additional code complexity and adds performance
overhead especially for nested virtualization.
These are documented here:

[mlir][llvm][OpenMP] Support iterator modifier in depend clause (#190026)
Add translation from the MLIR OpenMP depend clause with iterator
modifier to LLVM IR. `buildDependData` (in OpenMPToLLVMIRTranslation)
allocates a single `kmp_depend_info` array sized to hold both locator
(non-iterated) and iterated entries. Locator dependencies use the
existing static path (a vector of `DependData`), while iterated
dependencies use a dynamically-sized path (`DepArray`, `NumDeps`).
The reason both paths are not unified under the dynamic allocation is
that the existing locator path emits actual `kmp_depend_info` entries
inside OMPIRBuilder methods (`createTask`, `createTarget`), whereas the
iterator path must emit the iterator loop in OpenMPToLLVMIRTranslation
(since the convention is to not pass MLIR ops into the OMPIRBuilder).
Unifying them would require modifying existing depend clause tests.
The `OMPIRBuilder::DependenciesInfo` struct is extended to hold either a
`SmallVector<DependData>` (locator path) or a pre-built `{DepArray,
NumDeps}` pair (iterator path). The single-entry `emitTaskDependency`
helper is made public so the translation layer can fill individual
`kmp_depend_info` entries inside the iterator loop body.
This patch is part of the feature work for #188061.
Assisted with copilot.

[SamplePGO] Optimize the basename matching logic for matching unused profiles (#191523)
This change optimizes the basename matching logic in
`SampleProfileMatcher::matchFunctionsWithoutProfileByBasename` by
replacing the existing O(N*M) nested loop with an O(N+M) hash-based
lookup, while strictly preserving the original matching semantics. The
previous implementation relied on a substring heuristic
(`ProfName.contains(BaseName)`) to bypass expensive demangling
operations during the nested iteration; however, in codebases with
common or overlapping function names, this heuristic frequently
evaluated to true, resulting in redundant demangling and quadratic time
complexity. The updated approach demangles each profile name exactly
once and utilizes a `StringMap` to perform O(1) lookups against the
orphan functions. This eliminates the need for the substring pre-check
while maintaining the exact same constraints: establishing a strict 1:1
mapping between orphaned IR functions and profile entries, and correctly
identifying and rejecting ambiguous matches where multiple entities
share the same demangled basename.
Results in a 9x speedup on a large module with common basenames.

[flang] Implement conditional expressions lowering (F2023) (#186490)
## Implement Lowering for Fortran 2023 Conditional Expressions (R1002)
***This PR contains the lowering steps only for ease of review. DO NOT
MERGE until #186489 is merged.***
Implements Fortran 2023 conditional expressions with syntax: `result =
(condition ? value1 : condition2 ? value2 : ... : elseValue)`
Issue: #176999
Discourse:
https://discourse.llvm.org/t/rfc-adding-conditional-expressions-in-flang-f2023/89869/1
-- note that some of the details provided in the RFC post are no longer
accurate
### Implementation Details
**Lowering to HLFIR:**
- Lazy evaluation via nested if-then-else control flow
- Only the selected branch is evaluated
- Temporary allocation with proper cleanup
- Special handling for:
- CHARACTER types with deferred length
- Arrays (shape determined by selected branch per F2023 10.1.4(7))
- Derived types
**LIT Testing:**
- Lowering tests: HLFIR code generation verification
- Note: Executable tests will be added to the llvm-test-suite repo
(https://github.com/llvm/llvm-test-suite/pull/369)
**Limitations**
- Conditional arguments are not yet supported. This work is planned
- #180592
- Polymorphic types (CLASS) not yet supported in lowering
- Both limitations will emit clear error message if encountered
### Examples
```
! Simple conditional
x = (flag ? 10 : 20)
! Chained
result = (x > 0 ? 1 : x < 0 ? -1 : 0)
! Examples from F2023
( ABS (RESIDUAL)<=TOLERANCE ? ’ok’ : ’did not converge’ )
( I>0 .AND. I<=SIZE (A) ? A (I) : PRESENT (VAL) ? VAL : 0.0 )
```
AI Usage Disclosure: AI tools (Claude Sonnet 4.5) were used to assist
with implementation of this feature and test code generation. I have
reviewed, modified, and tested all AI-generated code.

[OpenACC] Fix IR verification failures in acc-specialize passes (#188961)
When MLIR_ENABLE_EXPENSIVE_PATTERN_API_CHECKS is enabled, the greedy
driver verifies the IR after each pattern application. The specialize
passes failed because ACCOpReplaceWithVarConversion would run on a data
entry op (e.g. acc.create) before container ops that use it in their
dataOperands were processed. After replacement, the container op held a
non-data-entry operand (e.g. a func arg), failing the acc dialect's
dataOperands verifier.
Fix: in ACCOpReplaceWithVarConversion, defer by returning failure() when
any user of the data entry op's result is a container op that validates
its operands as data entry ops (acc.data, acc.parallel, acc.serial,
acc.kernels, acc.host_data, acc.kernel_environment, acc.declare_enter,
acc.enter_data). The greedy driver will process the container op first
(via ACCRegionUnwrapConversion or ACCDeclareEnterOpConversion), removing
the use, after which the data entry op can be safely replaced.
Assisted-by: Claude Code

[clang][driver][AIX] Change linker bcdtor mode to default to mbr (#191265)
The bcdtor mode affects how the AIX linker choose to pull in static
constructors and destructors
(https://www.ibm.com/docs/en/aix/7.2.0?topic=l-ld-command) to the link.
The current setting of `all` makes static init in archive members live
regardless of if the archive member would be otherwise referenced,
causing that whole archive member to become part of the link.
This default was initially retained for compatibility purposes with
historical compilers on the platform which defaulted to this setting.
Unfortunately this greedy pulling in of static init can have unintended
consequences for applications, for example for programs linked against
parts of compiler-rt which contain optional instrumentation (containing
static initializers) which may be unused as these now become live in all
programs regardless of use.
For that reason and similar reasons, this PR switches the default to
`mbr`, which only extracts static init from archive members which would
otherwise be referenced. This gives a behaviour very consistent with
linkers on other platforms (e.g. Linux).
Users requiring the old default behaviour can manually pass
`-bcdtors:all` on the link step which will override any default we pass
here.

[CFG] Fix cleanup ordering for CXXDefaultInitExpr
(#191786)
Fixes CFG construction for default member initializers when
`AddCXXDefaultInitExprInCtors` is enabled by correcting the execution
order of cleanups.
E.g., in
```cpp
struct H {
std::string_view v = std::string("x");
H() {}
};
```
Previously, destructors for temporaries in default initializers
for`std::string("x")` was sequenced _before_ the member initialization,
causing false negatives in lifetime safety analysis because the
temporary appeared to be destroyed prematurely before making to a
origin.
Resolved this by modifying `CFGBuilder::addInitializer` to defer these
cleanups to the end of the initialization full-expression.

[LoopUnroll] Fix freqs for unconditional latches: N<=2 (#179520)
As another step in issue #135812, this patch fixes block frequencies
when LoopUnroll converts a conditional latch in an unrolled loop
iteration to unconditional. It thus includes complete loop unrolling
(the conditional backedge becomes an unconditional loop exit), which
might be applied to the original loop or to its remainder loop.
As explained in detail in the header comments on the
fixProbContradiction function that this patch introduces, these
conversions mean LoopUnroll has proven that the original uniform latch
probability is incorrect for the original loop iterations associated
with the converted latches. However, LoopUnroll often is able to perform
these corrections for only some iterations, leaving other iterations
with the original latch probability, and thus corrupting the aggregate
effect on the total frequency of the original loop body.
This patch ensures that the total frequency of the original loop body,
summed across all its occurrences in the unrolled loop after the
aforementioned conversions, is the same as in the original loop. Unlike
other patches in this series, this patch cannot derive the required
latch probabilities directly from the original uniform latch probability
because it has been proven incorrect for some original loop iterations.
Instead, this patch computes entirely new probabilities for the
remaining N conditional latches in the unrolled loop.
This patch only handles N <= 2, for which it uses simple formulas to
compute a single uniform probability across the latches. Future patches
will handle N > 2.
This patch series does not consider the presence of non-latch loop
exits, and I do not have a solid plan for that case. See fixme comments
this patch introduces.
This patch depends on PR #182403 and PR #191008.

[MLIR][Vector] Fix multi_reduction fold to handle empty reduction dims for any rank (#188983)
The fold for `vector.multi_reduction` only handled the rank-1 case with
no reduction dimensions. For higher-rank vectors (e.g.,
`vector<2x3xf32>`) with empty reduction dims `[]`, the fold returned
null, allowing `ElideUnitDimsInMultiDimReduction` to fire incorrectly.
That canonicalization pattern checks that all *reduced* dims have size
1, but with zero reduction dims the check trivially passes, and the
pattern then computes `acc op source` (e.g., `acc + source`) instead of
the correct no-op result (`source`).
This caused `--canonicalize` to produce a different value than
`--lower-vector-multi-reduction` for the same program:
vector.mask %m { vector.multi_reduction <add>, %src, %src [] :
vector<3x3xi32> to vector<3x3xi32> } : vector<3x3xi1> -> vector<3x3xi32>
* Without --lower-vector-multi-reduction: `src + src` (e.g., 2)
* With --lower-vector-multi-reduction: `src` (e.g., 1)
Fix the fold to return `source` for any rank when `reduction_dims` is
empty. This makes the empty-dims case consistent: the operation is a
noop regardless of rank, and `ElideUnitDimsInMultiDimReduction` no
longer gets a chance to mishandle it.

[MLIR][Shard] Fix three bugs in ND mesh resharding in Partition pass (#189241)
A new MoveLastSplitAxisPattern class handles the case where the last
grid axis of one tensor dimension is moved to the front of another
tensor dimension's split axes, e.g. [[0, 1], [2]] -> [[0], [1, 2]].
The three bugs fixed are:
1. detectMoveLastSplitAxisInResharding: compared source.back() with
target.back() instead of target.front(), preventing the pattern from
being detected for resharding like [[0,1],[2]] -> [[0],[1,2]].
2. targetShardingInMoveLastAxis: axes were appended with push_back but
should be inserted at the front, producing wrong split_axes order.
3. handlePartialAxesDuringResharding: a copy_if wrote results into the
wrong output variable (addressed structurally by the clean
implementation).

tilingResult.loops.front(), causing a crash:
- tileToForallOpImpl: the loop normalization block was entered whenever
mixedNumThreads was empty, regardless of whether any loops exist. Guard
it with \!tilingResult.loops.empty().
- TileUsingForallOp::apply: tileOps.push_back was called
unconditionally. Guard it with \!tilingResult.loops.empty().
Add regression tests for both the tile_sizes and num_threads paths,
verifying that the linalg.generic is preserved and no scf.forall is
emitted.

[mlir:python] Fix crash in from_python in type casters. (#191764)
This PR fixes a crash due to a failed assertion in the `from_python`
implementations of the type casters. The assertion obviously only
triggers if assertions are enabled, which isn't the case for many Python
installations, *and* if a Python capsule of the wrong type is attempted
to be used, so this this isn't triggered easily. The problem is that the
conversion from Python capsules may set the Python error indicator but
the callers of the type casters do not expect that. In fact, if there
are several operloads of a function, the first may cause the error
indicator to be set and the second runs into the assertion. The fix is
to unset the error indicator after a failed capsule conversion, which is
indicated with the return value of the function anyways.
In alternative fix would be to unset the error indicator *inside* the
`mlirPythonCapsuleTo*` functions; however, their documentations does say
that the Python error indicator is set, so I assume that some callers
