[AMDGPU] Fixed verifier crash because of multiple live range components. (#190719)
In Rewrite AGPR-Copy-MFMA pass, after replacing spill instructions, the
replacement register may have multiple live range components when the
spill slot was stored to more than once. The verifier crashes with a bad
machine code error. This patch fixes the problem by splitting a live
range but assigning the same physical register in this scenario. A new
test has been added that verifies the absence of this verifier error.

[NFC] [clangd] [C++20] [Modules] Introduce ProjectModules::getModuleNameState interface (#193133)
A hole in the current design is that, we assumed there is no duplicated
module name in different module interface in the same project.
This is not true techniquelly. ISO disallows duplicated module names in
a linked program. But we can have multiple program in a project. It will
be fine if they are not linked together. And in practice, it will be
fine if the symbols are masked and if these module interface units are
not showing in the same context of a single translation unit.
I am trying to improve this. This patch tries to add some NFC things to
reduce further patch size.
AI assisted.

[ELF] Parallelize input file loading (#191690)
During `createFiles`, `addFile()` records a `LoadJob` for each
non-script input (archive, relocatable, DSO, bitcode, binary) with a
state-machine snapshot (`inWholeArchive`, `inLib`, `asNeeded`,
`withLOption`, `groupId`) and expands them on worker threads in
`loadFiles()`. Linker scripts are still processed inline since their
`INPUT()` and `GROUP()` commands recursively call `addFile()`.
Outside `createFiles()`, `loadFiles()` is called with a single job and
drained immediately (`deferLoad` is false). Two cases:
- `addDependentLibrary()`: `.deplibs` sections trigger `addFile()`
during the serial `doParseFiles()` loop.
- `--just-symbols`: pushes files directly, bypassing
`addFile`/`LoadJob`.
Thread-safety:
- A mutex serializes `BitcodeFile` / fatLTO constructors that call
`ctx.saver` / `ctx.uniqueSaver`. Zero contention on pure ELF links.
- Thin-archive member buffers accumulate in per-job `SmallVector`s and
are merged into `ctx.memoryBuffers` in command-line order.
- `groupId` is pre-claimed during the serial walk and written to each
produced file after construction (the `InputFile` constructor no
longer reads `nextGroupId`).
Performance (--threads=8):
```
clang-relassert (267 thin archives, 10 .o, 2 .so):
965 +/- 32 ms -> 924 +/- 24 ms (1.05x, 80 runs)
(Apple M4) 249.7ms ± 2.5ms -> 221.2ms ± 1.4ms (1.13x, 10 runs)
chromium (532 .a, 3314 .o, 343 .so):
8.071 +/- 0.472 s -> 7.370 +/- 0.198 s (1.10x, 20 runs)
```
Parallelizing all file kinds (not just archives) matters for
.o-dominated workloads like chromium where archive-only parallelization
shows no improvement.
Output is byte-identical to the old lld and deterministic across
`--threads` values.

[X86] Quote symbol names that collide with registers/keywords in Intel syntax (#186570)
When outputting Intel syntax assembly, symbol names that match register
names (e.g., `rsi`, `rax`) or keywords (`byte`, `ptr`, etc.) must be
quoted, otherwise the assembler parses them as registers/keywords
instead of symbol references.
Fix this by populating MCAsmInfo::ReservedIdentifiers with all X86
register names and Intel syntax keywords. isValidUnquotedName() checks
this set and forces quoting when a symbol name matches.

merge, producing a linking error when that global gets discarded.
It is still possible to merge same comdats, or to merge a non-key comdat
constant into a non-comdat constant.

[clang-tidy][readability-identifier-length] Add a line count threshold (#185319)
This PR implements the feature described in #185318
A new parameter named `LineCountThreshold` is added to the
`readability-identifier-length` check, which controls how many lines of
code must separate the the last use of a variable from its declaration
for the check to warn. For backwards-compatibility, the default value
for this parameter is set to 0.
Increasing the threshold to 1 allows for short names in one-liners (for
example: `std::transform(..., [](auto i){ return i*i; });`), and in the
general case with `LineCountThreshold = N` a variable is allowed to have
a shorter name than otherwise required if it is never used again after
`N` lines (including its declaration line).
This feature is implemented ~using a secondary `MatchFinder`~ by calling
the `utils::decl_ref_expr::allDeclRefExprs` helper function for each
variable with a short name. For performance reasons, the new piece of
code is short-circuited if `LineCountThreshold` is set to 0 (the default
value).

You can tell an llvm build to use existing tools using options like
LLVM_NATIVE_TOOL_DIR.
When you do this, the tools are usually still built in case they need to
be part of a later install. For example if you provide a clang-tblgen,
we still build another clang-tblgen as part of the build.
Which means if you install that build, it is a complete install, and if
you are doing a cross build, you get a cross built copy of clang-tblgen
that you can use on the target machine.
In #159812, lldb-tblgen was added to the list of tools to install, so
that installed builds could be used as a base for subsequent builds.
However we were missing the EXPORT flag for lldb-tblgen. As far as I can
tell, this tells cmake that this tool will be part of the final install
regardless of whether something within the build requires it.
This missing option meant that cross builds, which do not have an
internal reason to build the cross lldb-tblgen binary, did not build it
did try to install it and of course failed because it did not exist.
Adding EXPORT forces lldb-tblgen to be built during the cross build and
now installing works as expected.

[lldb] Remove trailing newlines from AppendErrorWithFormat calls (#192965)
This call adds a newline if there isn't one. Changing these will
eventually let us always add a newline, which is in line with the other
methods on CommandReturnObject.
This is a small part of calls found with:
* VSCode search for
`(\.AppendErrorWithFormat\(([\s\r\n]+)?"(?:(?:\\.|[^"\\])*))\\n"` and
replace with `$1"`.
* Asserting that the last character of the format string is not a
newline.
* Manual inspection.

[libc++] Fix numeric_limits::digits and digits10 for _BitInt(N) (#193002)
`digits` was `sizeof(T) * CHAR_BIT - is_signed`, which counts padding
bits for non-byte-aligned widths. For example, `unsigned _BitInt(13)`
reported `digits=16` instead of `13`. Computing it from
`__builtin_popcountg(~unsigned_type(0))` gives the right answer: padding
bits stay zero after bitwise NOT, so the popcount matches the value-bit
width.
`digits10 = digits * 3 / 10` was also wrong for `digits >= 256` (gave
76, should be 77). The new formula `digits * 1936274 / 6432163` matches
`floor(digits * log10(2))` exactly for every `digits` in `[1, 8388608]`,
i.e. the currently biggest possible `__BITINT_MAXWIDTH__` on Clang.
This is part of the [_BitInt(N) libc++
effort](https://discourse.llvm.org/t/bitint-n-support-in-libc-investigations-possible-improvements-looking-for-guidance/90063).

[clangd] [C++20] [Modules] Read module mappings from commands (#193158)
A problem in the design of supporting modules in clangd is, we assume
there is no duplicated module name for different module units in a
single project. But this is not techniquelly correct.
What ISO disallow is, duplicated module name with different module units
in a linked program. But in a project, we can have multiple program.
And also in practice, the program will still work if users hidden
certain symbols. Tools can't detect that.
After all, we need to support the duplicated module unit within
different module units. The solution in the patch is to lookup into the
compile commands in compilation database.
e.g.,
```C++
clang++ -std=c++20 a/a.cppm -c -fmodule-output=a/a.pcm -o a/a.o
clang++ -std=c++20 b/a.cppm -c -fmodule-output=b/a.pcm -o b/a.o
clang++ -std=c++20 consumer1.cpp -fmodule-file=a=a/a.pcm -c -o
consumer1.o
clang++ -std=c++20 consumer2.cpp -fmodule-file=a=b/a.pcm -c -o
consumer2.o
```
By looking at the commands, we can relate 'a/a.cppm' to 'a/a.pcm' and
'b/a.cppm' to 'b/a.pcm'. And we know consumer1.cpp is consuming
'a/a.pcm' as module 'a', and consumer2.cpp is consuming 'b/a.pcm' as
module 'b'.
So finally we can relate 'a' and 'a/a.cppm' together for 'consumer1.cpp'
and 'a' and 'b/a.cppm' together for 'consumer2.cpp'.
Note that this is not the ideal solution. As the information in the
compile commands may be out of date. We've already used scanning as a
validating helper but, maybe, we still need a listening mechanism to
observe the change in every source in time.
But after all, this should work in most cases and this may be what we
can do with the least change right now.
(We need to update the cache system in
clang-tools-extra/clangd/ProjectModules.cpp to make it work reliably)

[flang][debug] Handle USE statements inside modules (#186184)
Previously, we only generated `fir.use_stmt` when a USE statement was
inside a function. USE statements inside modules were not handled,
resulting in missing debug information for transitive module
dependencies.
The problem can be seen with the following testcase:
```
module mod_a
integer :: x = 10
end module mod_a
module mod_b
use mod_a
integer :: y = 20
end module mod_b
program main
use mod_b
print *, x, y
end program main
```
We only generate `fir.use_stmt` for mod_b and nothing for `mod_a`,
making symbols from `mod_a` (like `x`) inaccessible in the debugger.
This PR solves this problem by introducing ModuleDebugImportsOp
which represents a use statement in a module. It is then used to
generate di_imported_entity in AddDebugInfo. Note that we generate
flattened debug information (one di_imported_entity for each use statement
that we can transitively reach in each function). This is to side step a
GDB issue (https://sourceware.org/bugzilla/show_bug.cgi?id=34034).

[LV][NFC] Remove unnecessary extra passes from some tests (#193155)
Many tests were running extra passes after loop-vectorize, but they made
no difference to the outcome. If tests don't require these extra passes,
then we shouldn't run them because it increases the testing time.

[LICM] Remove unnecessary check during store hoisting (#187529)
When hoisting stores, we check for interfering uses. This is done
by getting the clobbering def for the use and checking whether it
is outside the loop, which implies that no store in the loop can
interfere with it.
However, in addition to that, we check that the memory use does
not occur before the store. I believe that this additional check
is unnecessary, as if the use could be affected by the store, the
clobber walk would have pointed to the memory phi, not outside the
loop.
I think this check was added because MemorySSA had trouble with
loop-carried dependencies in the past (like in #54682), but this
should no longer be a problem.
This allows store hoisting in cases where there are unrelated
loads before the store.

[Attributor] Clarify volatile null pointer behavior (NFCI) (#193190)
The comment was referring to volatile stores in particular, which
are specified as non-willreturn. However, allowing volatile accesses
on null (independently of null_pointer_is_valid) is a general
provision that is independent of the access kind.
The actual behavior was still correct, because volatile loads are
considered as writing inaccessible memory, so the mayWriteToMemory()
check was ultimately redundant.
Add a test to make sure volatile load is handled correctly.

[mlir] Add option to run CSE between greedy rewriter iterations (#193081)
The greedy pattern rewrite driver previously only deduplicated constant
ops between iterations (via the operation folder). Structurally
identical non-constant subexpressions remained distinct SSA values,
blocking fold patterns that only fire when operands match. Reaching the
true fixpoint required chaining an external `cse,canonicalize,...`
pipeline.
Add an opt-in `cseBetweenIterations` flag on `GreedyRewriteConfig` that
runs full CSE on the scoped region after each pattern-application
iteration, and surface it as a `cse-between-iterations` option on the
canonicalizer pass. Off by default to preserve existing performance
characteristics.

[mlir][arith] Add `arith.flush_denormals` operation (#192641)
Add a new `arith.flush_denormals` operation. The operation takes a
floating-point value as input and returns zero if the value is denormal.
If the input is not denormal, the operation passes through the input.
This commit also adds support to the `ArithToAPFloat` infrastructure.
Running example:
```mlir
%flush_a = arith.flush_denormals %a : f32
%flush_b = arith.flush_denormals %b : f32
%res = arith.addf %flush_a, %flush_b : f32
%flush_res = arith.flush_denormals %res : f32
```
The exact lowering path depends on the backend and is not implemented as
part of this PR:
- Per-instruction mode. E.g., on NVIDIA architectures, the above example
can lower to `add.ftz.f32 dest, a, b`.
- Global status register. E.g., on `x86_64`, the above example can lower
to `_MM_SET_FLUSH_ZERO_MODE(_MM_FLUSH_ZERO_ON);
_MM_SET_DENORMALS_ZERO_MODE(_MM_DENORMALS_ZERO_ON); r = a + b;
_MM_SET_FLUSH_ZERO_MODE(_MM_FLUSH_ZERO_OFF);
_MM_SET_DENORMALS_ZERO_MODE(_MM_DENORMALS_ZERO_OFF);`. Subsequent
ON-OFF-ON switches can be folded away.
- Emulation via integer arithmetics. Check the bit pattern of the input
float (depending on the specific FP type) and pass-through either the
input or a zero constant. This lowering approach works on all
architectures.

[InstCombine] fold fabs(uitofp(i16 a) - uitofp(i16 b)) < 1.0 to a == b (#191378)
Fixes: https://github.com/llvm/llvm-project/issues/187088
When a and b are types with bitwidth (16 bits) smaller than the mantissa
for float32 (24 bits), they will be exact and their absolute difference
would be integral ±1 or greater if a != b. On the corollary, if their
difference is < 1.0, this implies that a = b.
This patch exploits this fact to fold the expression to just a single
icmp.

[Polly] Disable PCH reuse for unit tests (#193209)
Polly library targets already disable PCH reuse because Polly
unconditionally builds with -fno-rtti and -fno-exceptions. Reusing LLVM
PCHs that were built with RTTI or exceptions enabled is incompatible
with Clang when compiling Polly targets under those flags.
After 47eb8b43c990 enabled PCH reuse for unit tests, Polly unit tests
can hit the same mismatch as the library targets. Pass DISABLE_PCH_REUSE
through the shared add_polly_unittest wrapper so all Polly unit tests
follow the existing Polly target policy.

[SPIR-V] Deduce argument types before doing GEP (#193046)
In SPIRVEmitIntrinsics, we try to get the type for a GEP by looking at
the type of the input pointer, and deducing the output pointer type from
it. If the input pointer is a function parameter, we do not have the
type
available yet because we deduce the type of the parameters after
processing the GEPs.
There is no reason to have that order. Moving the parameter passes
earlier so the GEP type deduction works.
The same test exposed a problem with function parameter attributes. They
require Kernel, so we no longer emit them when creating a shader.

[RISCV] Further improved exact VLEN lowering for mul reductions (#192688)
This is a follow up to 973a05ed. When we have a horizontal multiply
reduction at high LMUL and we have exact knowledge of VLEN, we can
extract the individual m1 sub-vectors and perform the entire reduction
tree at m1. This reduces the work performed (by not performing high LMUL
operations on a vectors with empty tails), and decreases register
pressure. Interestingly, we don't even increase dynamic instruction
count as the register alignment of the original LMUL forced the use of
whole register moves in the tree reduction anyways. (In the non-exact
case, these are vslidedown instructions, and are required.)
Originally written by Claude Code, heavily revised by me.

VLOperands::reorder() from grouping consecutive loads on one side,
degrading downstream vectorization.
Normalize in two steps during buildOperands:
1) Majority voting: swap lanes that are the exact inverse of the
majority operand-type pattern.
2) Load preference: if the majority pattern has loads at OpIdx 1
(strict majority), swap to put loads at OpIdx 0, enabling
vector load + copyable patterns.
Recommit after revert at c2139f13606f0be8d09fa82a28e85dba4c3478dd, added
a check for commutative operations for reorder.

[lldb] Skip memory region probing in FindSpace when process can't JIT (#193124)
IRMemoryMap::FindSpace walks process memory regions via
GetMemoryRegionInfo to find addresses that won't shadow real process
memory. This crashes on targets like WebAssembly where the stub can
report the first memory region but fails for addresses beyond linear
memory, triggering an lldbassert.
When CanJIT() is false, all allocations are host-only and never written
to process memory, so probing the process memory map is unnecessary.
Skip it and fall through to the default address selection instead.

[LoopVectorize] Add minsize attribute to test (NFC) (#193223)
This test is intending to test the minsize behavior, but is missing the
attribute.
The actual result of doing that seems worse to me (because we get
predicated stores), but seems to align with expected behavior based on
other minsize tests. I think we might be too aggressive about disabling
epilogues when optimizing for size. Having an epilogue is probably
better than using store predication.
But we should test the behavior we currently have...

Hexagon is a 32-bit little-endian target with no native 64-bit
relocation. Map FK_Data_8 fixups to R_HEX_32 (or R_HEX_32_PCREL) so that
8-byte data directives (.8byte, .quad) referencing external symbols
produce valid relocations instead of a fatal error.
Also improve the diagnostic for unrecognized fixup kinds by including
the fixup kind number in the error message.

[SLP]Fix stale deps for operands of non-scheduled expanded-binop parents
When a parent tree entry does not require scheduling and contains an
expanded binop (e.g. `shl x, 1` modelled as `add x, x`), it never gets
a bundle. So, the operand's `ScheduleData::Dependencies` keeps the count
from the first sibling's `tryScheduleBundle` and misses later-added
entries sharing the same expanded scalar. At real scheduling,
`schedule()` then issues decrements for every current containing entry
and trips `UnscheduledDeps >= 0`.
Fixes #193040

[clang][NFC] Prevent scope pollution from repeat type specifiers (#193144)
Fixes #187664
When parsing `type-specifier {class,union,struct,enum,etc} nested-name`
ParseClassSpecifier and ParseEnumSpecifier both operated on the current
declaration scope on the assumption that they were the only type
specifier. Of course in incorrect code that assumption is false, and as
a result when parsing the name specifier they would pollute the the real
scope.
This is not relevant to the semantic correctness: the error is detected
and reported. The problem is that the subsequent state is not correct,
though not in a way that impacts functional behavior of release builds.
In assertion builds however this is detected (via a somewhat obtuse
path) when we attempt to plant namespace location information from the
invalid declaration on the initial declaration.
This PR fixes the state corruption by moving the name parsing in enum
and record type specifiers into a throwaway scope if the declaration
already has a type specifier.

[clang] Get the directory identity from `ModuleCache` instead of `FileManager` (#193070)
Using `FileManager`'s caching and deduplication functionality for
assigning identity to the module cache is handy, but it relies on two
assumptions:
* the rest of the compiler consistently calls
`FileManager::getOptionalDirectoryRef()` with `/*CacheFailure=*/false`
for the module cache path,
* the VFS is not caching failed stats for the module cache path.
This PR implements this functionality in the `ModuleCache` interface,
which is conceptually the right place for it. This PR enables us to land
the VFS simplifications in

[lldb][test] Add support for building Wasm test inferiors (#192872)
This PR adds support for building the test inferiors to WebAssembly.
Specifically, it allows you to configure a sysroot and resource dir
(pointing at the WASI SDK). The Wasm runtime can be configured through
the `LLDB_TEST_USER_ARGS`.
```
LLDB_TEST_TRIPLE:STRING=wasm32-wasip1
LLDB_TEST_SYSROOT:PATH=/path/to/wasi-sdk-32.0-arm64-macos/share/wasi-sysroot
LLDB_TEST_RESOURCE_DIR:PATH=/path/to/wasi-sdk-32.0-arm64-macos/lib/clang/22/
LLDB_TEST_USER_ARGS:STRING=--setting;platform.plugin.wasm.runtime-path=/path/to/iwasm;--setting;platform.plugin.wasm.runtime-args=--heap-size=1048576;--setting;platform.plugin.wasm.port-arg=-g=
```
With the configuration listed above I was able to confirm that I could
build and run a handful of C and C++ tests. To set expectations: lots of
tests are unsupported because they rely on things not available in Wasm
(e.g. shared libraries) or they use features currently unsupported in
LLDB (most notably: expression evaluation).

This patch adds dot intrinsic support to the rocdl dialect. Having these

allow us to lower thread local reductions involving `<=16bit` data more
effectively. This is in line with the spirit of `dot` intrinsic support
wrt existing edge dialects (`x86`, `nvvm`, `spirv`).

This matches ld-prime behavior.
https://reviews.llvm.org/D124336 allows linking against MacOS libraries,
but only if the architecture matches exactly.
https://reviews.llvm.org/D130683 allows linking against tbds with ABI

[X86][GlobalISel] Ignore non-vregs in regbank mapping (#182880)
`X86RegisterBankInfo`'s regbank-mapping helpers work under the
assumption that every register operand was a typed virtual register.
This caused `RegBankSelect` crashes when such operands reached these
helpers:
* `getInstrPartialMappingIdxs` called `MRI.getType()` on a non-vreg
operand.
* `getInstrValueMapping` then called `getValueMapping(PMI_None, ...)`
for it.
Skip non-virtual register operands in both helpers. This keeps non-vregs
out of LLT/mapping logic while still mapping real vreg operands.

[Compare

- The undocumented TRAP cache cleanup feature that could be enabled
using the `CODEQL_ACTION_CLEANUP_TRAP_CACHES` environment variable is
deprecated and will be removed in May 2026. If you are affected by this,
we recommend disabling TRAP caching by passing the `trap-caching: false`
input to the `init` Action.
[#3795](https://redirect.github.com/github/codeql-action/pull/3795)
- The Git version 2.36.0 requirement for improved incremental analysis
now only applies to repositories that contain submodules.
[#3789](https://redirect.github.com/github/codeql-action/pull/3789)
- Python analysis on GHES no longer extracts the standard library,
relying instead on models of the standard library. This should result in
significantly faster extraction and analysis times, while the effect on
alerts should be minimal.
[#3794](https://redirect.github.com/github/codeql-action/pull/3794)
- Fixed a bug in the validation of OIDC configurations for private
registries that was added in CodeQL Action 4.33.0 / 3.33.0.
[#3807](https://redirect.github.com/github/codeql-action/pull/3807)
- Update default CodeQL bundle version to
[2.25.2](https://redirect.github.com/github/codeql-action/releases/tag/codeql-bundle-v2.25.2).

- Fix incorrect minimum required Git version for [improved incremental
analysis](https://redirect.github.com/github/roadmap/issues/1158): it
should have been 2.36.0, not 2.11.0.

- Reduced the minimum Git version required for [improved incremental
analysis](https://redirect.github.com/github/roadmap/issues/1158) from
2.38.0 to 2.11.0.
[#3767](https://redirect.github.com/github/codeql-action/pull/3767)
- Update default CodeQL bundle version to
[2.25.1](https://redirect.github.com/github/codeql-action/releases/tag/codeql-bundle-v2.25.1).

- Downgrade default CodeQL bundle version to
[2.24.3](https://redirect.github.com/github/codeql-action/releases/tag/codeql-bundle-v2.24.3)
due to issues with a small percentage of Actions and JavaScript
analyses.

[`v4.34.0`](https://redirect.github.com/github/codeql-action/releases/tag/v4.34.0)
[Compare
Source](https://redirect.github.com/github/codeql-action/compare/v4.33.0...v4.34.0)
- Added an experimental change which disables TRAP caching when
[improved incremental
analysis](https://redirect.github.com/github/roadmap/issues/1158) is
enabled, since improved incremental analysis supersedes TRAP caching.
This will improve performance and reduce Actions cache usage. We expect
to roll this change out to everyone in March.
[#3569](https://redirect.github.com/github/codeql-action/pull/3569)
- We are rolling out improved incremental analysis to C/C++ analyses
that use build mode `none`. We expect this rollout to be complete by the
end of April 2026.
[#3584](https://redirect.github.com/github/codeql-action/pull/3584)
- Update default CodeQL bundle version to
[2.25.0](https://redirect.github.com/github/codeql-action/releases/tag/codeql-bundle-v2.25.0).
[#3585](https://redirect.github.com/github/codeql-action/pull/3585)

[Compare
Source](https://redirect.github.com/github/codeql-action/compare/v4.32.6...v4.33.0)
- Upcoming change: Starting April 2026, the CodeQL Action will skip
collecting file coverage information on pull requests to improve
analysis performance. File coverage information will still be computed
on non-PR analyses. Pull request analyses will log a warning about this
upcoming change.
[#3562](https://redirect.github.com/github/codeql-action/pull/3562)
To opt out of this change:
- **Repositories owned by an organization:** Create a custom repository
property with the name `github-codeql-file-coverage-on-prs` and the type
"True/false", then set this property to `true` in the repository's
settings. For more information, see [Managing custom properties for
repositories in your
organization](https://docs.github.com/en/organizations/managing-organization-settings/managing-custom-properties-for-repositories-in-your-organization).
Alternatively, if you are using an advanced setup workflow, you can set
the `CODEQL_ACTION_FILE_COVERAGE_ON_PRS` environment variable to `true`
in your workflow.
- **User-owned repositories using default setup:** Switch to an advanced
setup workflow and set the `CODEQL_ACTION_FILE_COVERAGE_ON_PRS`
environment variable to `true` in your workflow.
- **User-owned repositories using advanced setup:** Set the
`CODEQL_ACTION_FILE_COVERAGE_ON_PRS` environment variable to `true` in
your workflow.
- Fixed [a
bug](https://redirect.github.com/github/codeql-action/issues/3555) which
caused the CodeQL Action to fail loading repository properties if a
"Multi select" repository property was configured for the repository.
[#3557](https://redirect.github.com/github/codeql-action/pull/3557)
- The CodeQL Action now loads [custom repository
properties](https://docs.github.com/en/organizations/managing-organization-settings/managing-custom-properties-for-repositories-in-your-organization)
on GitHub Enterprise Server, enabling the customization of features such
as `github-codeql-disable-overlay` that was previously only available on
GitHub.com.
[#3559](https://redirect.github.com/github/codeql-action/pull/3559)
- Once [private package
registries](https://docs.github.com/en/code-security/how-tos/secure-at-scale/configure-organization-security/manage-usage-and-access/giving-org-access-private-registries)
can be configured with OIDC-based authentication for organizations, the
CodeQL Action will now be able to accept such configurations.
[#3563](https://redirect.github.com/github/codeql-action/pull/3563)
- Fixed the retry mechanism for database uploads. Previously this would
fail with the error "Response body object should not be disturbed or
locked".
[#3564](https://redirect.github.com/github/codeql-action/pull/3564)
- A warning is now emitted if the CodeQL Action detects a repository
property whose name suggests that it relates to the CodeQL Action, but
which is not one of the properties recognised by the current version of
the CodeQL Action.

- Repositories owned by an organization can now set up the
`github-codeql-disable-overlay` custom repository property to disable
[improved incremental analysis for
CodeQL](https://redirect.github.com/github/roadmap/issues/1158). First,
create a custom repository property with the name
`github-codeql-disable-overlay` and the type "True/false" in the
organization's settings. Then in the repository's settings, set this
property to `true` to disable improved incremental analysis. For more
information, see [Managing custom properties for repositories in your
organization](https://docs.github.com/en/organizations/managing-organization-settings/managing-custom-properties-for-repositories-in-your-organization).
This feature is not yet available on GitHub Enterprise Server.
[#3507](https://redirect.github.com/github/codeql-action/pull/3507)
- Added an experimental change so that when [improved incremental
analysis](https://redirect.github.com/github/roadmap/issues/1158) fails
on a runner — potentially due to insufficient disk space — the failure
is recorded in the Actions cache so that subsequent runs will
automatically skip improved incremental analysis until something changes
(e.g. a larger runner is provisioned or a new CodeQL version is
released). We expect to roll this change out to everyone in March.
[#3487](https://redirect.github.com/github/codeql-action/pull/3487)
- The minimum memory check for improved incremental analysis is now
skipped for CodeQL 2.24.3 and later, which has reduced peak RAM usage.
[#3515](https://redirect.github.com/github/codeql-action/pull/3515)
- Reduced log levels for best-effort private package registry connection
check failures to reduce noise from workflow annotations.
[#3516](https://redirect.github.com/github/codeql-action/pull/3516)
- Added an experimental change which lowers the minimum disk space
requirement for [improved incremental
analysis](https://redirect.github.com/github/roadmap/issues/1158),
enabling it to run on standard GitHub Actions runners. We expect to roll
this change out to everyone in March.
[#3498](https://redirect.github.com/github/codeql-action/pull/3498)
- Added an experimental change which allows the `start-proxy` action to
resolve the CodeQL CLI version from feature flags instead of using the
linked CLI bundle version. We expect to roll this change out to everyone
in March.
[#3512](https://redirect.github.com/github/codeql-action/pull/3512)
- The previously experimental changes from versions 4.32.3, 4.32.4,
3.32.3 and 3.32.4 are now enabled by default.

[#3493](https://redirect.github.com/github/codeql-action/pull/3493)
- Added an experimental change which improves how certificates are
generated for the authentication proxy that is used by the CodeQL Action
in Default Setup when [private package registries are
configured](https://docs.github.com/en/code-security/how-tos/secure-at-scale/configure-organization-security/manage-usage-and-access/giving-org-access-private-registries).
This is expected to generate more widely compatible certificates and
should have no impact on analyses which are working correctly already.
We expect to roll this change out to everyone in February.
[#3473](https://redirect.github.com/github/codeql-action/pull/3473)
- When the CodeQL Action is run [with debugging enabled in Default
Setup](https://docs.github.com/en/code-security/how-tos/scan-code-for-vulnerabilities/troubleshooting/troubleshooting-analysis-errors/logs-not-detailed-enough#creating-codeql-debugging-artifacts-for-codeql-default-setup)
and [private package registries are
configured](https://docs.github.com/en/code-security/how-tos/secure-at-scale/configure-organization-security/manage-usage-and-access/giving-org-access-private-registries),
the "Setup proxy for registries" step will output additional diagnostic
information that can be used for troubleshooting.
[#3486](https://redirect.github.com/github/codeql-action/pull/3486)
- Added a setting which allows the CodeQL Action to enable network
debugging for Java programs. This will help GitHub staff support
customers with troubleshooting issues in GitHub-managed CodeQL
workflows, such as Default Setup. This setting can only be enabled by
GitHub staff.
[#3485](https://redirect.github.com/github/codeql-action/pull/3485)
- Added a setting which enables GitHub-managed workflows, such as
Default Setup, to use a [nightly CodeQL CLI
release](https://redirect.github.com/dsp-testing/codeql-cli-nightlies)
instead of the latest, stable release that is used by default. This will
help GitHub staff support customers whose analyses for a given
repository or organization require early access to a change in an
upcoming CodeQL CLI release. This setting can only be enabled by GitHub
staff.

enabled](https://docs.github.com/en/actions/how-tos/monitor-workflows/enable-debug-logging),
the CodeQL Action will now use more unique names when uploading logs
from the Dependabot authentication proxy as workflow artifacts. This

[clang][bytecode][HLSL] Complete the HLSL aggregate splat and elementwise cast implementations, and enable the new constant interpreter on all HLSL tests with static asserts (#189126)
This PR fixes https://github.com/llvm/llvm-project/issues/183426,
completing the implementations of `CK_HLSLAggregateSplatCast` and
`CK_HLSLElementwiseCast` in Clang's new bytecode-based constant
expression evaluation engine / interpreter.
This PR also adds new RUN lines with
`-fexperimental-new-constant-interpreter` to all HLSL tests that have
static assertions.
The tests exercising the `CK_HLSLAggregateSplatCast` and
`CK_HLSLElementwiseCast` implementations in the new constant interpreter
are
- `clang/test/SemaHLSL/Types/AggregateSplatConstantExpr.hlsl` and
- `clang/test/SemaHLSL/Types/ElementWiseConstantExpr.hlsl`
respectively.

[clang][deps] Simplify scanner VFS (#190843)
This PR removes a hack from the scanning VFS that introduced a bypass
mechanism for module cache queries. Now that we go through the
`ModuleCache` interface for implicitly-built modules, this is no longer
necessary.

[LV] Remove IV use restrictions for epilogue vectorization. (#190552)
There have been a number of improvements to epilogue handling over the
last year, including improved resume value handling and consistent final
induction value handling via ExitingIVValue.
With those, the restriction can be removed, as direct uses of induction
phis are already handled correctly.

[Clang] Diagnose UB and emit error when identifier has both internal and external linkage (#192116)
C11 6.2.2p7 says if the same identifier appears with both internal and
external linkage in a translation unit, the behavior is undefined.
This patch adds a check in `Sema::MergeVarDecl` that uses
`LookupResult::isShadowed()` to detect when a block-scope `extern` found
a file-scope `static` through a shadow, and emits an error.
Fixes #54215

range is zero.

[lldb] Make global lookup in DIL configurable by caller (#192592)
DIL has supported unlimited global lookup, which is in contrast with
long standing `frame variable` behavior, which supports only globals
from the current file.
This is semantically incorrect for frame variable, and has shown to
produce bugs in `dwim-print`. For these reasons, this change makes
global lookup opt-out, controlled by a new
`eExpressionPathOptionsDisallowGlobals` flag.
For `dwim-print`, the bug manifests when a global shadows a computed
property of the instance variable (`self`). As an example, if a global
named `text` exists, and a property named `text` exists (ie
`self.text`), then running `dwim-print text` will unexpectedly print the
global, not `self.text`.

[JTS] Add a temporary workaround for multiple zero GUIDs (#193292)
We can sometimes end up with multiple zero values in the VP metadata if
profile loading cannot map multiple addresses to their functions. We
should probably eventually fix this case in the profile loader, but as a
temporary workaround, handle this in JTS explicitly by dropping the
assertion, similar to how this is handled in ICP.
This is similar to #192905, but with more researched justification.

[AMDGPU] Reland "Fixed verifier crash because of multiple live range components." (#190719) (#193286)
PR #190719 was reverted by PR #193135 because a .s file was left behind
by a test. This patch fixes it by adding -filetype=null to the RUN line
of the test rewrite-vgpr-mfma-to-agpr-spill-multi-store.ll.
In Rewrite AGPR-Copy-MFMA pass, after replacing spill instructions, the
replacement register may have multiple live range components when the
spill slot was stored to more than once. The verifier crashes with a bad
machine code error. This patch fixes the problem by splitting a live
range but assigning the same physical register in this scenario. A new
test has been added that verifies the absence of this verifier error.

[BOLT] Fix stream position before appendPadding in writeEHFrameHeader (#193126)
When writeEHFrameHeader needs to allocate new space for .eh_frame_hdr
(because the old section is too small), it calls appendPadding to align
NextAvailableAddress. appendPadding writes zero bytes at the current
stream position, but after the section write loop in rewriteFile the
stream is positioned at the end of the last section written in
BinarySection::operator< order — not at the file offset corresponding to
NextAvailableAddress.
In the common case (single loadObject call) the write order matches file
offset order, so the stream happens to be in the right place. But when a
runtime library adds sections via additional loadObject calls, the
operator< iteration order (code-before-data) can diverge from file
offset order: a runtime library code section may have a higher file
offset than a runtime library data section that comes after it in the
write loop. The stream then ends at a lower offset than expected, and
appendPadding's zeros overwrite the beginning of the code section.
Fix by seeking to the correct file offset before calling appendPadding.

[libc] Add wcsxfrm (#191692)
This patch adds wcsxfrm to LLVM libc.
It includes:
- wchar.yaml declaration
- implementation and header
- CMake wiring
- entrypoint registration
- unit tests
The current implementation provides C/POSIX-style behavior and does not
yet add locale-aware collation support.
Tested with:
- ninja libc.test.src.wchar.wcsxfrm_test
Notes:
- local full check-libc was blocked by unrelated pre-existing timeout
failures in other tests.
Fixes #191074

# Contents
* Adds a new warning that is emitted on use-after-free.
* Renames `reportUseAfterFree` to `reportUseAfterScope` due to the old
name being misleading (warnings are still called `use_after_scope`).
* Adds a new `AccessPath::Kind` value `NewAllocation` that is used for
loans issued from `new` allocations.
* Adds `VisitCXXNewExpr` and `VisitCXXDeleteExpr`, which handle loan
issuance / origin propagation for `new` / `delete`.
* Comes with extensive testing of the new features (including new
use-after-free tests, and use-after-scope coverage for `new`).

[lldb] Add synthetic variable support to Get*VariableList. (#181501)
This patch adds a new flag to the lldb_private::StackFrame API to get variable lists: `include_synthetic_vars`. This allows ScriptedFrame (and other future synthetic frames) to construct 'fake' variables and return them in the VariableList, so that commands like `fr v` and `SBFrame::GetVariables` can show them to the user as requested.
This patch includes all changes necessary to call the API the new way - I tried to use my best judgement on when to include synthetic variables or not and leave comments explaining the decision.
As a consequence of producing synthetic variables, this patch means that ScriptedFrame can produce Variable objects with ValueType that contains a ValueTypeExtendedMask in a high bit. This necessarily complicates some of the switch/case handling in places where we would expect to find such variables, and this patch makes best effort to address all such cases as well. From experience, they tend to show up whenever we're dealing with checking if a Variable is in a specified scope, which means we basically have to check the high bit against some user input saying "yes/no synthetic variables".

[CIR] Cache isSafeToConvert results to avoid redundant record layout … (#193122)
…walks
CIRGenTypes::isSafeToConvert() walks record layouts to determine whether
a struct can be safely converted to MLIR types. The walk recurses into
field types and re-runs for the same record every time it is asked, so
workloads with many distinct record types (template-heavy code in
particular) repeat substantial work.
Cache the boolean result in a per-CIRGenTypes DenseMap keyed by the
RecordDecl. Lookup becomes O(1) after the first walk per type.
The impact in isolation is modest — on a synthetic stress with many
records and template instantiations, end-to-end compile time on `clang
-fclangir -S -emit-llvm -O0` improves by roughly 2-3% (e.g. 16.59s ->
16.09s on a 67K-LOC input).
Repro shape (scale records and template instantiations into the
hundreds/thousands to amplify):
```
template <typename T, int N> struct Box { T head; Box<T, N-1> tail; };
template <typename T> struct Box<T, 0> { T head; };
struct R0; struct R1;
struct R0 { int v; Box<int, 4> b; R1* next; };
struct R1 { long v; Box<long, 4> b; R0* next; };
int f0(R0*); int f1(R1*);
int f0(R0* r) { return r->v + (r->next ? f1(r->next) : 0); }
int f1(R1* r) { return (int)r->v + (r->next ? f0(r->next) : 0); }

[compiler-rt][profile] Use runtimes-libc-headers in the GPU runtimes build (#192814)
When compiler-rt is built for a GPU target in the same runtimes build
as LLVM-libc, the profile sources `#include <string.h>`, `<limits.h>`,
... Those headers are generated by LLVM-libc for the GPU triple.
A concrete example is the amdgcn runtimes build:
-DLLVM_RUNTIME_TARGETS='default;amdgcn-amd-amdhsa'
-DRUNTIMES_amdgcn-amd-amdhsa_LLVM_ENABLE_RUNTIMES='compiler-rt;libc'
-DRUNTIMES_amdgcn-amd-amdhsa_RUNTIMES_USE_LIBC=llvm-libc
Even though `libc` is configured before `compiler-rt`, both sets of
targets live in the same ninja graph and race each other. Ninja can
start compiling `compiler-rt/lib/profile/InstrProfiling.c` before
LLVM-libc has finished generating its GPU `string.h`, and even when
hdrgen has finished, the profile compile needs `-isystem` pointing at
the generated header tree.
Use the runtimes-side libc-provider abstraction in
`runtimes/cmake/Modules/HandleLibC.cmake`:
- at compiler-rt top level, `include(HandleLibC)` when
`LLVM_RUNTIMES_BUILD` is set, so all compiler-rt subcomponents can
reuse the `runtimes-libc-*` targets. `libcxx` / `libcxxabi` /
`libunwind` include it the same way at their top-level CMakeLists.
- in `compiler-rt/lib/profile/CMakeLists.txt`, when the GPU build
sees the sibling `runtimes-libc-headers` target, pass it through
`LINK_LIBS` of `add_compiler_rt_runtime(clang_rt.profile ...)`.
In the `llvm-libc` case this pulls in LLVM-libc's `libc-headers`
(`-isystem <build>/include/<triple>`), waits for
`generate-libc-headers`, and adds `-nostdlibinc` so the profile compile
does not consult host C library paths.
The dependency is added only when `COMPILER_RT_GPU_BUILD` is on and the
sibling `runtimes-libc-headers` target actually exists, so host
compiler-rt builds, standalone compiler-rt builds, and runtimes builds
without LLVM-libc selected are unchanged.
`add_compiler_rt_runtime` passes `LINK_LIBS` to
`target_link_libraries(<libname> PRIVATE ...)`, so the include path is
used when compiling the profile target itself but is not propagated to
downstream consumers of `libclang_rt.profile.a`.

[mlir][func] Avoid to create duplicate symbol during conversion (#192342)
`LLVM::lookupOrCreateFn` only checks for an existing `LLVM::LLVMFuncOp`
before creating a new function declaration. When a symbol with the same
name exists as a different op type (e.g., `func.func` that hasn't been
converted to LLVM dialect yet), the function blindly creates a duplicate
`LLVMFuncOp`, which either causes a "redefinition of symbol" error or
silently introduces a renamed symbol (`@free_0`) that won't resolve at
link time.
This happens in practice when user code declares function that is also
used internally by MLIR lowerings. For example, a Fortran `bind(c,
name="free")` declaration produces a `func.func @free` in the IR. When
`memref.dealloc` is lowered (via DeallocOpLowering), it calls
lookupOrCreateFreeFn which calls lookupOrCreateFn — and since the
existing `func.func @free` is not an LLVMFuncOp, a conflicting duplicate
is created.
The fix adds a check in lookupOrCreateFn: before creating a new
LLVMFuncOp, it verifies that no symbol with the requested name already
exists in the module (regardless of op type). If one does, it returns
failure() so the calling conversion pattern can be retried after the
existing symbol is converted by another pattern (e.g., func-to-llvm).

`llvm/docs/LFI.rst` for more details. They contain fixed constants or
temporaries used as part of assembly-level rewrites of load/store
instructions. The rewriter will reject programs that attempt to write to
these registers. It is technically OK to save/read them (in
`UnwindRegistersSave.S`), but there is no point since there is no need
to restore them (and to maintain LFI's security invariant, they in fact
cannot be written).

[BoundsSafety][NFC] Move LateParsedAttribute outside Parser class; move LateParsedAttrList to DeclSpec.h (#192145)
Preparatory refactoring for llvm/llvm-project#179612, which introduces
late parsing of bounds-safety attributes as type attributes. The new
approach needs LateParsedAttribute accessible from DeclSpec.h (to store
late attr pointers in DeclaratorChunk, Declarator, and DeclSpec), which
cannot depend on Parser.h.
- Move LateParsedDeclaration and LateParsedAttribute to namespace level
in Parser.h
- Move LateParsedAttrList to DeclSpec.h with a forward declaration of
LateParsedAttribute
Other LateParsedDeclaration subclasses (LateParsedClass,
LateParsedPragma, LateParsedMemberInitializer, etc.) remain inside
Parser as they are only created and consumed within Parser and don't
need to cross the Parser/Sema boundary.

[runtimes] Enable Fortran only with explicit CMAKE_Fortran_COMPILER (#193332)
Only enable Fortran support when the user (or the bootstrapping build)
passes `-DCMAKE_Fortran_COMPILER=...`.
`enable_language(...)` other than C/CXX reveals problems with the
current build system. LLVM likes to add
`-Wl,--color-diagnostics`
to `CMAKE_EXE_LINKER_FLAGS` whenever possible. The problem is that
`CMAKE_EXE_LINKER_FLAGS` is added to the linker line regardless of which
language is used, but `HandleLLVMOptions.cmake` probes only
`CMAKE_CXX_COMPILER`. Other languages' compilers such as
`CMAKE_CUDA_COMPILER` (`nvcc`) or `CMAKE_Fortran_COMPILER` (`gfortran`)
may not accept the flag. CMake then fails when those compilers are "not
able to compile a simple test program." because it does not accept the
`--color-diagnostics` flag.
`CMAKE_EXE_LINKER_FLAGS` does not support generator expression such that
`$<$<COMPILE_LANGUAGE:C,CXX>:-Wl,--color-diagnostics>` does not work
either.
We disable automatic detection of a Fortran compiler out of precaution
if other such problems are found. The bootstrapping build will pass
just-built Clang and Flang together which are compatible to each other.
In runtimes default/standalone builds, users will have to pass the
compiler explicitly if they want Fortran modules.

[offload] Fix synchronization when record replay is enabled (#193291)
When kernel record replay was enabled, the operations on the current
stream were not synchronized. That's because the current stream was
"ignored", and a new stream was used when RR is active. This is invalid
when there are pending operations on the original stream and can lead to
invalid prologue recording data.
This commit addresses this issue by using the original stream and
synchronizing it explicitly before and after kernel launch. This way, we
ensure the operations are completed before performing the prologue and
epilogue data recording. Additionally, the kernel record replay entry
points are moved to the same layer, in `GenericKernelTy::launch()`.

[ConstantFolding] Increase folding limit for vector loads to 128 bytes (#192775)
In FoldReinterpretLoadFromConst, ReadDataFromGlobal bails out when
BytesLoaded exceeds 32 bytes. This prevent folding in our downstream
OpenCL case where global constant is [16 x float] array and is loaded as
float16 vector, which is 64 bytes.
This PR increases BytesLoaded cap to 128 bytes, to accommodate large
vector support, e.g. double16 type in OpenCL. For scalar integer load,
the limit remains 32 bytes to avoid regression on load from string
literal.

[PDB] Refactor cache strategy for function symbol lookups (#188927)
The original algorithm only caches the symbols that are being queried.
The module needs to be decoded again and again even when looking up the
same symbol but different address. This is time consuming when looking
for a large amount of symbol info. This patch uses IntervalMap to cache
decoded symbols to avoid duplicate decoding. We tested the symbol lookup
time for all symbols in symtab for Blender. The time was shortened by
258x relative to the original algorithm. This will greatly improve the
experience of loading symbols for pseudo probe on Windows.

Updates example python commands to use `SBExecutionContext` where
beneficial. This was to remove uses of
`GetSelected{Target,Thread,Frame}`.
While making this changes, I also renamed `dict` parameters to
`internal_dict`. In examples, it's better not to shadow `dict`, which is
the builtin type and constructor for dictionaries.
Lastly, I removed a command (`section_ptr_refs`) whose function was
disabled, and non-functional (it calls a non-existent function
`load_dylib`).

[llvm-mc][AsmMatcherEmitter] Fix the minimum ConversionTable entry size (#191977)
When working on a target with fully customized instruction
conversion method, there's a build failure due to the case that in the
target's generated asm matcher, the size of `ConversionTable` entry is 2
(i.e., the minimum size defined in `AsmMatcherEmitter` TableGen
backend).
However, for a target that has customized conversion method for all
instructions, a `ConversionTable` entry should be looking like: `{
CVT_<the-custom-conversion-method>, <the-position-of-operand>, CVT_Done
}`, where the position of operand for custom conversion is by-default 0.
This commit includes a test case to illustrate this scenario, along with
a little fix.

[clangd] Add go-to-definition support for fields in offsetof expressions (#192953)
clangd had no handling for OffsetOfExpr in FindTarget.cpp, so
go-to-definition and find-references on field names inside
__builtin_offsetof(Type, field) produced no results.
Fix this by adding VisitOffsetOfExpr to both visitors:
- The TargetFinder visitor in add(const Stmt*) so that allTargetDecls()
resolves the referenced FieldDecl(s).
- The refInStmt visitor so that findExplicitReferences() emits a
ReferenceLoc per field component, enabling find-references and rename to
locate each field at its source position.
Each OffsetOfNode of kind Field is visited; Identifier nodes (unresolved
dependent-type designators) and Base nodes (implicit base-class
indirections) are intentionally skipped.
Repro:
```
struct Foo { int bar; };
int x = offsetof(Foo, bar); // go-to-def on `bar` previously did nothing
```

Following of https://github.com/llvm/llvm-project/pull/193158
Although https://github.com/llvm/llvm-project/pull/193158 handles
duplicated module name, the cache in ModulesBuilder still uses the old
assumption.
This patch tries to resolve the problem while not affecting original use
cases as much as possible. As the duplicated module name should be rare
in real world case.

[CIR][AArch64] Lower NEON vminv intrinsics (#192901)
### Summary
part of : https://github.com/llvm/llvm-project/issues/185382
Lower all intrinsics in
https://arm-software.github.io/acle/neon_intrinsics/advsimd.html#minimum-across-vector
and
https://arm-software.github.io/acle/neon_intrinsics/advsimd.html#minimum-across-vector-(IEEE754)
Add ClangIR (CIR) codegen support for the NEON minimum-across-vector
builtins on AArch64. This covers the ACLE sections 2.1.1.13.4 Minimum
across vector (signed/unsigned integer + float) and 2.1.1.13.6 Minimum
across vector (IEEE 754, NaN-ignoring). Corresponding
classic-CodeGen-only tests are migrated into the shared CIR+LLVM test
file so both pipelines are checked from the same RUN lines.
These builtins are already registered in AArch64SISDIntrinsicMap
(clang/include/clang/Basic/AArch64CodeGenUtils.h) with the correct
LLVMIntrinsic IDs and TypeModifiers, mirroring the classic CodeGen flow
in
clang/lib/CodeGen/TargetBuiltins/ARM.cpp::EmitCommonNeonSISDBuiltinExpr.
In CIR the same map drives emitCommonNeonSISDBuiltinExpr, so the only
missing piece was adding these builtin IDs to the dispatch switch — no
intrinsic-specific lowering is needed.

[libcxx][test] Skip cas_non_power_of_2.pass.cpp in Picolibc build (#191415)
Relates to #191388
This test is currently being run and failing to link, however this is
masked by the XFAIL for clang 21. It is also marked unsupported for 22,
for now.
I ran it with 23 and got this linker error:
```
| ld.lld: error: undefined symbol: __atomic_load
<...>
| ld.lld: error: undefined symbol: __atomic_compare_exchange
```
This happens because for 5 and 6 byte variables, we can't simply
generate code for the atomic, so we emit a library call, and the
picolibc build does not provide implementations of these functions.
Presumably we could fix that, so I opened an issue to track that.
In the meantime, I want to make sure this doesn't start failing when CI
is updated to clang 23.
I decided to disable the whole test instead of the alternatives, which
are:
* Adding some extra feature like has-atomic-lib-calls. I wasn't sure
what was a good name for it, or how to write an accurate check for it.
* ifdef-ing out the 5 and 6 byte part with `__PICOLIBC__`. It's not a
problem with picolibc but our specific build type. I don't want to take
coverage away from anyone else's build.

should be zero (and we can remove the X86vzmovl node).
This patch adds a X86vzelts PatLeaf to help match more general cases
where we can use the result of a passthrough node (in this case
X86vzload) is known to be zero in the upper elements via value tracking,
allowing us to fold to VMOVSHZ (but not remove the passthrough node).

[lldb] Fix pexpect detection with LLDB_ENFORCE_STRICT_TEST_REQUIREMENTS (#193444)
Fixes ec8df555702d85511290742388d28016b69468de / #193437.
In which I tried to not require pexpect on Windows because key parts of
it do not work there
(https://pexpect.readthedocs.io/en/stable/overview.html#windows).
Which I did but made a mistake which removed pexpect from the list of
required modules for *all* platforms as a side effect.
`list(APPEND pexpect)` creates an empty list called foo
(https://cmake.org/cmake/help/latest/command/list.html#append), I meant
to append to the useful modules list.
With that fixed, we require pexpect everywhere apart from Windows.
GitHub CI is already installing pexpect on Linux
(see .ci/all_requirements.txt). All the Linux bots using
LLDB_ENFORCE_STRICT_TEST_REQUIREMENTS have it installed. The Linux
remote testing bots don't use that option but pexpect tests don't run
when remote anyway.

[mlir][spirv] Add SPV_EXT_FP8 type support to SPIR-V TOSA ops (#193199)
Add SPV_EXT_FP8 support for SPIR-V TOSA ops by updating the shared type
definitions and extending op constraints for the newly supported element
types.
Also update verifier coverage to reflect the new constraints:
- refresh existing negative tests whose diagnostics now list FP8 types
- add negative tests for SPV_EXT_FP8-specific output, weight,
accumulator, and cast restrictions

[Passes] Remove Os and Oz optimization pipelines (#191363)
These should use O2 with the optsize or minsize attributes instead.
This enforces that there is no divergence between pipeline-level Os/Oz
and function-level Os/Oz at an architectural level.
For the purpose of testing IR that does not have optsize/minsize itself,
it's possible to use `-force-attribute=optsize` etc.

[Flang][OpenMP] Fix DEFAULT(NONE) check for Cray pointers in nested OpenMP directives (#190764)
Fixes - [#190750](https://github.com/llvm/llvm-project/issues/190750)
In resolve-directives.cpp, the handling of DEFAULT(NONE) for Cray
pointers in nested OpenMP regions was incomplete.
The existing implementation only checked the data-sharing attribute
(DSA) of the Cray pointee, and did not account for the associated Cray
pointer. This led to incorrect diagnostics when the pointee was used
inside a region, but the pointer’s DSA was not properly considered.
This patch updates the logic to:
1. Check DSAs for both the Cray pointee and its corresponding pointer
2. Restrict the validation to the current directive context, ensuring
that each default(none) region enforces its own data-sharing
requirements
3. Introduce a helper (initSymbolDSA) to reuse DSA lookup logic
With this change, nested default(none) regions correctly require the
Cray pointer to be explicitly listed in each region, and diagnostics are
issued when either the pointer or pointee is missing a DSA in the
current context.
A test case has also been added to cover this scenario.

[clang][ssaf][NFC] Rework how the Force linker anchors are defined and used (#189409)
- Moves them to the `clang::ssaf` namespace.
- Drops the custom force linker header used for testing, because all
object files are directly linked into the unittest executable, so we
don't need special handling there. This reduces complexity.
- Updates the documentation to reflect the new use.

CIR was hardcoding poisonZero=true for all clz/ctz builtins, ignoring

like AArch64 where clz/ctz of zero is well-defined.
Also add support for __builtin_c[lt]zg fallback (2-arg) variants with
compare+select, and add NYI stubs for elementwise variants.

flushDenormalConstant always created a scalar ConstantFP even when

return a ConstantFP. This can be reverted when ConstantFP vectors are
enabled by default (although additional work is required to support
zero).

[LV] Change VPLane::getAsRuntimeExpr to use constant 64-bit indices (#193206)
The canonical form preferred by instcombine is to use 64-bit values for
the index when it is a constant. We should try to do the same where
possible in the loop vectoriser as this reduces churn in the compiler.
It also makes other work easier, such as removing extra unnecessary
passes on the RUN line in the test directory which I plan to do
afterwards.

[mlir][linalg] Fix crash when folding tensor.cast into unpack using static packed shape for inner tiles (#188000)
This change fixes #187975 and #188405, a crash in Linalg tensor-cast
folding for pack/unpack when tile sizes are dynamic or otherwise not
provably constant.
Previously, canonicalization could reach getNewMixedTileSizes and
unconditionally access `getConstantIntValue(tile).value()`. For dynamic
tile operands, that value can be absent, causing
`std::bad_optional_access/assert` aborts.
When folding `tensor.cast` into `linalg.unpack` (and the same helper is
used for linalg.pack), mixed inner tile sizes are updated from the
refined packed tensor type. Every static trailing packed dimension gets
a matching static tile attribute, replacing SSA tile values and
overwriting tile constants that disagreed with that type.
Dynamic packed dimensions still keep the original tile operands.

[mlir][GPU] Refactor GPUOps lowering (#188905)
This change promotes `gpu.func` / `gpu.launch` metadata that was
previously carried as discardable attributes into proper inherent ODS
fields (`kernel`, `workgroup_attributions`), renames the block-argument
helpers to avoid clashing with generated getters, and routes `func.func`
and `gpu.func` lowering through a shared helper that maps discardable
`llvm.*` attributes into `llvm.func` properties.
Downstream producers (Flang CUDA device func transform, kernel
outlining, sparse GPU codegen, XeGPU) set kernels via `setKernel(true)`
instead of manually attaching `gpu.kernel`.
Fixes #185174

[clang] Suppress glibc C11 extension warning in `c-index-test` (#193335)
`c-index-test.c` is still compiled with `-std=gnu89` on purpose. That acts
as a useful guard rail: it helps keep the file compatible with older C
dialects instead of silently picking up newer C features because Clang
defaults to a newer language mode.
Ubuntu 26.04 LTS updates glibc's `string.h` so `strchr`, `strrchr` and
`strstr` are routed through `_Generic`-based macros. When Clang compiles
`c-index-test.c` with `-std=gnu89` and `-pedantic`, that now triggers
`-Wc11-extensions` warnings even though the source itself is not using
C11 features.
Keep the gnu89 check in place and suppress this warning only for Clang
when building c-index-test.

[debugserver][NFCI] Factor out logic handling breakpoint packets (#192912)
This creates a helper function that can be shared with the upcoming
MultiBreakpoint packet.
It is largely NFC with one logging exception: where we were previously
sending an "ILL_FORMED" error, we would identify the file/line in the
location where the error was emitted. This has been lost, however the
error messages are still unique enough that the line can be recovered
from the error message, and this is a principle we've been trying to
follow.
There was also a comment about gdb and refcounting of breakpoints. Such
comment was removed as it did not seem applicable to any line of code.

RFC](https://discourse.llvm.org/t/defining-what-happens-when-a-bool-isn-t-0-or-1/86778/).
``bool`` values are stored as i8 in memory, and it is undefined behavior
for a ``bool`` value to be any value other than 0 or 1. Clang exploits
this with range metadata: ``bool`` load instructions at any optimization
level above -O0 are assumed to only have their lowest bit set. This can
create memory safety problems when other bits are set, for instance
through ``memcpy``.
This change allows users to configure this behavior in three ways:
* ``-fstrict-bool`` represents the status quo; range metadata is added
at levels above -O0 and allows the compiler to assume in-memory ``bool``
values are always either 0 or 1.
* ``-fno-strict-bool[={truncate|nonzero}]`` disables range metadata on
``bool`` loaded values and offers two ways to interpret the loaded
values. ``truncate`` means the value is true is the least significant
bit is 1 and false otherwise; ``nonzero`` means the value is true if any
bit is 1 and false otherwise.
The default is ``-fstrict-bool`` to not change the current behavior of
Clang. The default behavior of ``-fno-strict-bool`` is ``truncate``.

the instructions used to implement the reduction inside the loop are no
different from when implementing this as a regular reduction.

[SPIR-V] Handle [N x i8] byte addressing in SPIRVEmitIntrinsics (#192994)
LLVM started generating [N x i8] types on array indexing GEPs. Emit
intrinsiscs did not know what to do with it so it was generating a
cast to [N x i8] to perform the GEP. This does not work in logical
addressing.
The handle this, we expand the `i8` gep handling for logical addressing
mode to work for arbitrary size byte addressing.

The patch is a preparatory step for sinking invariant stores in licm. We

are sinking, in order to prevent sinking assumes: without this change,
there is a bad test update in tree. Unfortunately, as the only possible
instructions without users that will not be trivially dce'd, and on
which the vectorizer will not bail out are, are stores and assumes:
since we forbid assume-sinking, and store sinking will only be done in a
follow-up, we have no test changes to show.

[InstCombine] Remove support for volatile in phi of load transform (#193154)
The volatile support does not have test coverage, and dates back to when
this transform was originally introduced 20 years ago, so it does not
appear that volatile support was specifically added -- it was just
naively implemented to start with, and then received bug fixes.
The current implementation is still buggy, e.g. it allows sinking
volatile past inaccessiblemem calls, which is invalid (as those may
contain volatile accesses on allocas).
After https://github.com/llvm/llvm-project/pull/192992, there would be
another constraint that all the instructions after the volatile load are
speculatable.
This wouldn't be hard to fix, but I'd rather remove volatile support
here entirely.

[bolt] AArch64: Fix TLSDESC to LE relaxation by mold (#190370)
mold linker creates relaxation stub from TLSDESC to LE, (lld makes it
IE) using sequence as NOP+NOP+MOVZ+MOVK. This in itself is not an issue,
when --emit-relocs is added the relocs R_AARCH64_TLSDESC_ADD_LO12 and
R_AARCH64_TLSDESC_CALL are associated with useful MOVW instructions.
However bolt does not check for R_AARCH64_TLSDESC_ADD_LO12 in
adjustRelocation() when disassembling the file. This later triggers a
bug when reloc is patched as movk is patched with S_LO12 fixup kind
which is invalid.

details.

[SPIRV] Fix legalization of zero-sized intrinsic globals (#192730)
Some LLVM global intrinsics like `llvm.global_ctors` may become
zero-sized arrays if all constructors are inlined/optimized out.
These variables use appending linkage, which is only valid on arrays,
however as we are lowing to a pointer, this causes invalid IR if we
maintain the same linkage.
Use `ExternalWeak` linkage, the only other mergable linking type allowed
for intrinsic global variables with definitions. We also need to not
specify an initializer to not produce an invalid module.
As these variables do not represent user visible code, and all entries
were optimized out anyway, the new linkage should be fine.

[MachineCopyPropagation][NFC] Refactor EliminateSpillageCopies (#192609)
This patch builds on the original implementation to address areas that
may impact compile time regression if enabled. The aim of the patch is
to streamline and improve the implementation for better compile time
impact. A summary of the changes is as follows:
- Cost modelling that does an initial scan of the block, any blocks with
less than 6 copies are immediately skipped.
- RegMask scan in `findLastSeenDefInCopy` removed. This now only checks
the recorded copies to ensure that RegMasks are clobbered when they are
seen if they clobber a Reg
- Streamlining of `IsSpillReloadPair` and `IsChainedCopy` to reduce the
need for a second call to isCopyInstr to get the DestSourcePair, these
are now returned from the lamdba function
- Use of TRI API to get the CommonRegClass

[DAG] visitFREEZE - revisit frozen node after merging with unfrozen uses (#188206)
After merging other uses of a N to all use FREEZE(N), make sure we
revisit FREEZE(N) to attempt to push the FREEZE through the (now
hasOneUse()) operand.
The only remaining annoyance I can find is the freeze nodes interfering
with amdgpu scalar/vector instructions - mainly because we end up with
more freeze(vectorload) patterns and extract_vector_elt nodes can't peek
through anymore - this is an ongoing general problem that nobody has
found a good answer to yet.

[RISCV] Functional llvm.vector.reduce.mul on scalable types (#193094)
RVV does not have an instruction for performing a horizontal multiply
reduction (either integer or floating point). However, a user of clang
can explicitly write at least the integer form via the
__builtin_reduce_mul construct, and currently we just crash when
compiling this.
This change converts the crash into functionally correct scalar loop to
process each element one by one at runtime. This will be slow, but at
least correct.
Note that to my knowledge we can't generate the floating point one
directly from C, but I decided to handle both for completeness while I
was here.
Written by Claude Code with guidance and review by me.

[libc] Add struct sockaddr_storage (on linux) (#192978)
This deceptively simple patch has one catch. The POSIX standard states:
"""
When a pointer to a sockaddr_storage structure is converted to a pointer
to a sockaddr structure, or vice versa, the ss_family member of the
sockaddr_storage structure shall map onto the sa_family member of the
sockaddr structure. When a pointer to a sockaddr_storage structure is
converted to a pointer to a protocol-specific address structure, or vice
versa, the ss_family member shall map onto a member of that structure
that is of type sa_family_t that identifies the protocol's address
family. When a pointer to a sockaddr structure is converted to a pointer
to a protocol-specific address structure, or vice versa, the sa_family
member shall map onto a member of that structure that is of type
sa_family_t that identifies the protocol's address family. Additionally,
the structures shall be defined in such a way that the compiler treats
an access to the stored value of the sa_family_t member of any of these
structures, via an lvalue expression whose type involves any other one
of these structures, as permissible, despite the more restrictive
expression rules on stored value access as stated in the ISO C standard.
...
Note that defining the sockaddr_storage and sockaddr structures using
only mechanisms defined in early editions of the ISO C standard may
produce aliasing diagnostics when applications use casting between
pointers to the various socket address structures. Because of the large
body of existing code utilizing sockets in a way that could trigger
undefined behavior due to strict aliasing rules, this standard mandates
that these structures can alias each other for accessing the sa_family_t
member of the structures (or other members for protocol-specific
structure references), so as to preserve well-defined semantics. An
implementation's header files may need to use anonymous unions, or even
an implementation-specific extension, to comply with the requirements of
this standard.
"""
To satisfy this requirement I add the may_alias attribute on all the
sockaddr structures.

[mlir] targeted verification for transform "inlining" (#192956)
When merging named transform sequences into their include locations,
rely on the InlinerDialectInterface implementation newly added to the
transform dialect instead of the full verification after the fact. This
enables us to only verify aspects of the IR that may change in a way
compatible with the rest of the infra, reducing the overall cost of the
process.
Use `LogicalResult` as appropriate instead of returning dummy
`InFlightDiagnostic` while I'm here.

[ItaniumDemangle] Strip __alloc_token_ to transparently demangle allocation functions (#191048)
Update the Itanium demangler to recognize and strip `__alloc_token_`
prefixes introduced by AllocToken instrumentation [1]. This ensures that
instrumented allocation functions (e.g., `__alloc_token__Znwm`) demangle
back to their original source-level names (e.g., `operator new(unsigned
long)`) with a suffix `(.alloc_token)` indicating their non-standard
origin.
Since AllocToken is intended to be transparent to users who continue to
use `operator new` as before, the demangled name should reflect this
reality instead of confusing users with internal instrumentation names
in stack traces or symbolization output.
Synchronize changes across llvm and libcxxabi copies.

[OpenMP][OMPIRBuilder] Support complex types in atomic update/capture (#191490)
Route struct-typed values through the libcall path in
`emitAtomicUpdate`.
Previously, the libcall path was gated on `RMWOp == BAD_BINOP`, so
atomic capture swap patterns (`v = x; x = expr`) for complex values
lowered as structs fell through to the cmpxchg path. That path called
`getScalarSizeInBits()` on a struct type, produced 0, and triggered an
assertion in `IntegerType::get()`.
Remove the `BAD_BINOP` restriction so struct types always use the
libcall path. This is safe because the libcall path does not use `RMWOp`
and already handles arbitrary type sizes correctly.
Also fix `LoadSize` in the libcall path to use `XElemTy` rather than the
pointer type, which previously gave the wrong size for larger complex
types such as `complex(8)`.

This code calls `getInitializer` without checking if the global has an
initializer, which causes an assert if there isn't one. These globals
may have no initializer after optimization from `globalopt`.
Check for an initializer first.
This is already locked down with
`CodeGen/SPIRV/legalize-zero-size-arrays-appending.ll` so we don't need
a new test.

[Support][JSON] Use `std::unordered_map` for object storage (#171230)
`llvm::DenseMap` is not suitable for the key-value `Storage` inside
`llvm::json::Object`. Use `std::unordered_map` instead to optimize
memory usage.
`llvm::DenseMap` is optimized for mapping small keys and values
(pointers), and it pre-allocates 64 buckets by default.
`llvm::json::ObjectKey` is 24 bytes in size, and `llvm::json::Value` is
40 bytes. Currently, the JSON parser allocates 4KB of memory for each
JSON object. In practice, most JSON objects contain only a handful of
fields, and likely to have lists of many small objects. This is a
significant waste of memory.

So we can use them in static_asserts in #192862.
It converts what ever is trivially possible. In future more can

[MLIR][XeGPU] Do not use ocloc lib if LLVM_BUILD_LLVM_DYLIB is ON (#193259)
This fixes LLVM dylib build in environments with installed ocloc.
The problem is that LLVM shared lib is never linked with ocloc and the
linker fails to resolve the symbols `oclocInvoke` and `oclocFreeOutput`.

[lldb] Decorate tests that use threading (#193117)
Add a new decorator `skipIfTargetDoesNotSupportThreads` to skip tests
that use threading. This is motivated by running the test suite
targeting WebAssembly, where `wasip1` does not support threads. There
are variants that do support threading (e.g. `wasip1-threading`) that
the current implementation accounts for.

This narrows `FindSymbolsWithNameAndType` calls from searching all
loaded images to the specific module that owns the symbol (Foundation,
CoreFoundation, libBacktraceRecording.dylib).
The arclite fallback in `CalculateHasNewLiteralsAndIndexing` still
searches all images because libarclite is a static library linked into
the main executable.

For scalable vectors, pass the maximum runtime step to

the original trip count directly, if MaxRuntimeSteps divides the
original trip count without remainder.
In those cases, all lower power-of-2 vscales will divide the rip count
without remainder.

SSUBO: use the equivalent formulation: overflow when (LHS < RHS)
disagrees with (result < 0) instead of (result < LHS) vs (RHS > 0).

Reland: [MemProf] Dump inline call stacks as optimization remarks (#193545)
This iteration limits the test case to x86_64-linux to prevent bot
failures.
---
This patch teaches the MemProf matching pass to dump inline call
stacks as analysis remarks like so:
frame: 704e4117e6a62739 main:10:5
frame: 273929e54b9f1234 foo:2:12
inline call stack: 704e4117e6a62739,273929e54b9f1234
The output consists of two types of remarks:
- "frame": Acts as a dictionary mapping a unique MD5-based FrameID
to source information (function name, line offset, and column).
- "inline call stack": Provides the full call stack for a call site
as a sequence of FrameIDs.
Both types of remarks are deduplicated to reduce the output size.
This patch is intended to be a debugging aid.

[CIR] Support guard COMDAT for weak linkage in LoweringPrepare (#193274)
Static locals inside inline functions get `linkonce_odr` linkage, and
their guard variables need their own COMDAT groups so the linker can
deduplicate them across TUs. We were hitting an NYI error for this case
in `LoweringPrepare`.
The fix is straightforward: set `guard.setComdat(true)`, which makes
`LowerToLLVM` create a per-symbol COMDAT selector — the same thing
classic codegen does at `ItaniumCXXABI.cpp:2798`.
I ran into this while trying to compile the Bullet physics engine
through CIR. Functions like `btMatrix3x3::getIdentity()` use this
pattern (return a reference to a function-local static from an inline
member function), and 6 of the 121 source files were failing because of
it. With this fix, all 121 compile cleanly.

The previous (V, Op) pair insert was a no-op since V is unique per iteration.
Replace it with a hasOneUse() fast path plus a check that bails only when I
has a user outside the grandparent PHI's Scalars. Uses within the same
vectorized PHI are tracked by the existing dep machinery; an external user
(e.g. a scalar PHI in a different block) is what trips scheduleBlock's
"must be scheduled at this point" assertion.
Fixes #193315.

[CIR] Fix lowering of strings in constant array attributes (#193553)
There was code in the CIR CXXABILowering pass that was assuming
ConstArrayAttr::getElts() would return an ArrayAttr. This isn't true in
the case of string constants with trailing zeros, so we had a crash in a
mlir::cast<> call. The problem only appeared when a string array
appeared in the same initializer as a type that required CXXABI-specific
lowering, such as a member pointer.
This change fixes the CXXABILowering to simply keep the existing string
attribute, which is known to be legal for the purposes of that pass.

[flang][OpenMP] Support user-defined declare reduction with derived types (#190288)
Fix lowering of `!$omp declare reduction` for intrinsic operators
applied
to user-defined derived types (e.g., `+` on `type(t)`). Previously, this
hit a TODO in `ReductionProcessor::getReductionInitValue` because the
code
tried to compute an init value for a non-predefined type, when it should
instead use the initializer region from the `DeclareReductionOp`.
This fixes the issue #176278: [Flang][OpenMP] Compilation error when
type-list in declare reduction directive is derived type name.
The root cause was a naming mismatch: `genOMP` for
`OpenMPDeclareReductionConstruct` used a raw operator string (e.g.,
"Add")
as the reduction name, while `processReductionArguments` at the use site
computed a canonical name via `getReductionName` (e.g.,
"add_reduction_byref_rec__QFTt"). The `lookupSymbol` in
`createDeclareReductionHelper` never found the already-created op, so it
fell through to `createDeclareReduction` which called
`getReductionInitValue` with the derived type and hit the TODO.
The fix has four parts:
1. Consistent names: In `genOMP` for `OpenMPDeclareReductionConstruct`,
compute the reduction name using the same `getReductionName` scheme that
`processReductionArguments` uses, so both sites produce identical symbol
names. For intrinsic operators, this maps through `ReductionIdentifier`
to
get the canonical name. For user-defined named reductions, the raw
symbol
name is used directly, matching the existing custom-reduction lookup
path.
2. Reuse reduction: In `processReductionArguments`, when an intrinsic
operator reduction is requested, check whether a user-defined declare
reduction already exists under that canonical name before attempting to
create a new one. If found, reuse it. This avoids calling
`createDeclareReduction` (and thus `getReductionInitValue`) for types
that
have user-provided initializers.
3. Reference semantics: Change `doReductionByRef` to return true for
derived types. Previously it returned false for both trivial and derived
types, treating derived types as by-val. This is incorrect for
user-defined combiners that operate on components via side-effects
(e.g.,
`omp_out%x = omp_out%x + omp_in%x`): the combiner mutates `omp_out` in
place and does not produce a whole-struct value, so `convertExprToValue`
returns the component type (`i32`) rather than the struct type, causing
a
type mismatch in the `omp.yield`. By-ref is the correct model: the
combiner stores into the lhs reference and yields it.
The combiner callback in `processReductionCombiner` is also updated to
handle the by-ref derived-type case: when the combiner result type does
not match the element type (as happens with component-level
assignments),
the store is skipped since the assignment already wrote into omp_out as
a
side-effect, and only the lhs reference is yielded.
4. GPU codegen for non-descriptor by-ref reductions: The GPU reduction
codegen in OMPIRBuilder unconditionally called the `DataPtrPtrGen`
callback for all by-ref elements, assuming descriptor-based pointer
indirection was always needed. For simple derived types (e.g., a struct
with scalar integer members), there is no Fortran descriptor/box, so
`dataPtrPtrRegion` is empty and `DataPtrPtrGen` is null. This caused a
`std::bad_function_call` crash (or an assertion failure in
`getSingleElement` when the empty region was inlined).
The fix returns a null `DataPtrPtrGen` callback from `makeRefDataPtrGen`
when `dataPtrPtrRegion` is empty, and guards all call sites in
OMPIRBuilder to skip descriptor indirection when `DataPtrPtrGen` is
null.
For non-descriptor by-ref reductions, the pointer already references the
data directly--no indirection is needed.
Tests:
- Update declare-reduction-intrinsic-op.f90 from a negative test
(checking for the TODO error) to a positive test checking generated
MLIR.
- Update omp-declare-reduction-derivedtype.f90 CHECK lines to match the
reference semantics fix.
- Add declare-reduction-finalizer.f90 for derived type with init and
finalization.
Remaining work: declare reduction without an initializer clause is not
yet
supported.

[Clang][AST] Introduce `ExplicitInstantiationDecl` to preserve source info and fix diagnostic locations (#191658)
This is the initial fix of
https://github.com/llvm/llvm-project/issues/191442. Following the
discussion here
https://github.com/llvm/llvm-project/issues/115418#issuecomment-2467017012.
- Fix #21040
- Fix #52659
- Fix #115418
- Fix #14230
- Fix #21133
### Description
This PR introduces a new AST node, `ExplicitInstantiationDecl`, to
systematically fix the long-standing issue of missing or incorrect
source location information for explicit template instantiations.
#### Background & The Problem
Historically, Clang's AST lacked a dedicated node to represent the
lexical occurrence of an explicit instantiation statement. Instead,
`Sema` tried to shoehorn this information into existing specialization
nodes (e.g., `FunctionDecl`, `VarTemplateSpecializationDecl`) or simply
returned `nullptr`.
This resulted in fragmented behavior across the seven instantiable
entity types:
* Function & Member Function Templates: Returned `nullptr`, completely
losing `SourceRange` and `NestedNameSpecifier` information.
* Member Functions & Static Data Members: Mutated existing nodes
in-place. Consequently, multiple `template` or `extern template`
declarations in the same file would overwrite each other's source
locations.
* Variable Templates: Suffered from `dyn_cast` bugs and dropped NNS
information.
#### Design Trade-offs Evaluated
Before settling on the current design, I evaluated a mixed
redeclaration-chain approach (similar to how explicit *specializations*
are handled, creating new `FunctionDecl` nodes and stitching them into
the redecl chain). However, this approach had significant flaws:
1. Inconsistency: It couldn't be cleanly applied to member functions or
static data members due to `DeclContext` constraints (e.g., a member
function shouldn't lexically reside in a namespace `DeclContext`, but
placing it in the class context would pollute member lookup).
2. Fragility: It required bypassing standard `FoldingSet` mechanisms
(`setFunctionTemplateSpecialization`).
3. Lookup Pollution: Injecting new `NamedDecl` nodes purely for
instantiations risked breaking downstream `ASTMatcher`s and altering
name lookup behavior.
To avoid these pitfalls, this PR introduces `ExplicitInstantiationDecl`
as a **purely lexical annotation node**.
**Key Design Characteristics:**
1. Inherits from `Decl`, not `NamedDecl`: This is the most crucial
design choice. Much like `StaticAssertDecl` or `FriendDecl`, this node
lives in a `DeclContext` (making it traversable by `RecursiveASTVisitor`
and visible in AST dumps) but remains completely invisible to C++ name
lookup. It does not interfere with overload resolution or lookup tables.
2. Unified Representation: A single node type now covers all seven
entity types. It holds a pointer (`Specialization`) to the underlying
instantiated declaration, unifying how functions, variables, classes,
and members are handled.
3. Lexical Fidelity: The node resides in the enclosing namespace or
Translation Unit where the explicit instantiation was actually written,
perfectly preserving the `SourceRange`, `NestedNameSpecifierLoc`, and
the exact locations of the `template` and `extern` keywords.

[clang][Modules] Avoid checking for duplicating module definitions when a module does not have a valid definition location (#193534)
69e0367e8221b8002b5d438fb70ff3daf36257fc enhanced the duplicating module
definition diagnostics to check across ModuleMaps in a very specific
case. The check proved to be overly strict. This PR makes sure we do not
check when the `Existing` module's definition location is unknown. Such
cases are only observed when a module built through include-tree (CAS)
is imported through a pch (e.g.

Such cases are only present when CAS is used, so no test case is
attached here.

[HLSL] Reuse temporaries of aggregate types in list initialization (#191605)
When aggregate types appear as _prvalues_ in HLSL initializer lists, convert them to _xvalues_ and wrap them in `OpaqueValueExpr` so the temporaries can be reused across all element accesses. This allows code generation to avoid emitting redundant copies of the same aggregate temporary.
This should be especially helpful once support for constructors on user-defined structs is removed, and initializer lists will be the primary mechanism for struct initialization.
A similar optimization may also be applicable to vector and matrix types. However, their current code generation path does not yet support handling `OpaqueValueExpr` in initializer lists.

[BOLT] Fix null pointer dereference in DWP processing with split DWARF (#191474)
Fix two null pointer dereferences in BOLT's DWP processing path that
cause SIGSEGV in worker threads when -update-debug-sections is used with
a co-located .dwp file.
1. getSliceData() in updateDebugData() dereferences the result of
getContribution() without checking for null. getContribution() returns
nullptr when the requested section kind (e.g. DW_SECT_LINE) is not
present as a column in the DWP CU index. When BOLT processes a DWP where
certain section kinds are absent from the index, every worker thread
that hits this path crashes simultaneously.
2. processSplitCU() dereferences getUnitDIEbyUnit() without checking for
null. If buildDWOUnit() fails for a CU, the returned DIE* is null and
the dereference crashes.
Crash signature from dmesg:
```
llvm-worker-*: segfault at 8 ip <offset> error 4 in llvm-bolt
(multiple worker threads crash at the same instruction)
```
The faulting address 0x8 corresponds to accessing the Length field
(offset 8) of a null `DWARFUnitIndex::Entry::SectionContribution*`.
At Meta, I reproduced this building hhvm with a co-located .dwp file and
the flags `update-debug-sections -debug-thread-count=80 -lite=0` with
profile data.
I confirmed that the unfixed BOLT crashes deterministically whereas the
fixed BOLT completes successfully.

caused subsequent globals to be created in a detatched state, which in
turn led to crashes when lowering uses of those globals to the LLVM
dialect.
This change updates `lastGlobalOp` when the global it is referencing is
replaced.

[flang] Fix inline transfer for unsigned integer types (#193570)
Fix a crash when transfer is used with Fortran unsigned types. The
arith.bitcast op requires signless integer or float operands, but the
inline optimization was applying it to unsigned integer types (ui32),
causing a verification failure. Changed the guard from
mlir::isa<mlir::IntegerType> to isSignlessIntOrFloat() so unsigned
integer transfers fall through to the address-level fir.convert path
instead.
This is to fix a regression reported here:

AMDGPU: Skip last corrections in afn f64 reciprocal (#183696)
Device libs has a fast reciprocal macro that is close

compared to the full division.
The basic reciprocal handling has identical output to this
macro. The negative reciprocal case has different fneg placement
and smaller code size, but I believe should be the same.

[lldb] Fix empty backtraces for scripted threads with no artificial frames (#193387)
Following 86aa43999bec, `ScriptedThread::LoadArtificialStackFrames`
unconditionally calls `SetAllFramesFetched` even when the scripted
thread provided zero artificial stack frames via `get_stackframes`.
This prevents the normal unwinder from creating frames from the register
context, leaving `m_frames` empty. When GetFrameAtIndex(0) is
subsequently called, it triggered the follow on assertion builds:
```
assert(!m_thread.IsValid() && "A valid thread has no frames.")
```
This affects scripted threads that provide register context via
`get_register_context` but rely on the unwinder for frame creation
rather than overriding `get_stackframes`.
This patch fixes the issue by returning early in
`LoadArtificialStackFrames` in case the scripted thread StackFrame array
is empty, preventing it from calling `SetAllFramesFetched` on it's
StackFrameList.

[SLP]Fix dominance for multi-use copyable scalars in scheduled bundle
scheduleBlock skips copyable bundle members with their own ScheduleData,
leaving them at their original position. If such a scalar comes after
MainOp and satisfies doesNotNeedToBeScheduled, the vectorized op is
inserted at LastScheduledInst while the scalar stays behind, so the
insertelement feeding the copyable lane fails to be dominated by it.
After placing bundle members, move copyable scalars with more than one
use (same block as MainOp, doesNotNeedToBeScheduled, schedulable from
the tree entry's view) to just before LastScheduledInst.
Fixes #193513.

Ensure that the Synthetic children of a ValueObject are managed by their parents ClusterManager (#192561)
A very common pattern in our synthetic child providers was to make the
child ValueObject using ValueObjectConstResult::Create or some form of
the static ValueObject::CreateValueObjectFrom*** methods, and store and
hand that out as the child. Doing that creates a "root" ValueObject
whose lifecycle is not linked to the lifecycle of the ValueObject it is
a child of. And that means it is possible that either the child or the
parent could have gotten destroyed when the other ValueObject gets asked
a question about it.
For the most part this doesn't happen because there are usually enough
other shared pointer references binding the two to keep both sides
alive. But we have gotten a small but steady stream of reports for years
now of crashes where a ValueObject accesses its ClusterManager but that
has already been deleted. I've never been able to find a reproducible
case of this, but one plausible cause is that we are violating the
contract that "all the children of a ValueObject have coterminous
lifespans, enforced by the ClusterManager". So it is unsurprising that
they might sometimes not stay alive as long as they should.
This patch addresses that by providing a way to use these static create
methods but passing in the ClusterManager to be used, and adds or
modifies where extant the CreateChildValueObjectFrom*** methods to pass
in the parent manager.
This patch is not complete. It turns out that routing the ClusterManager
from CreateValueObjectFromExpression all the way to where the expression
result VO is made is quite intrusive, and would have made this already
quite large (though largly mechanical) patch become unweildy. Since I am
mostly concerned about synthetic child providers, and we discourage
using expressions for them, I think that's an acceptable separation.
I also added a test where the ValueObjectSynthetic hands out its
children, checking whether the child being handed out is in fact owned
by the parent handing it out. It is controlled by a setting
(target.check-vo-ownership) which is currently off by default - since I
can't provide a way to do this correctly for expressions yet. But I turn
it on in the testsuite. That's the real testing strategy for this patch,
since its goal is to ensure that all the children we hand out are
managed by their parents. I didn't put an equivalent check in
ValueObjectVariable because that system really doesn't allow a way to do
this incorrectly.
I also fixed some of the tests that were making children using
CreateValueObjectFromExpression to make their children with
CreateValueObjectFromData instead. I could have opted the tests out of
the check, but using the expression parser to do this work is not best
practice, so I didn't want to leave bad examples around. I left one case
that does do it with expressions, however, so we still have a test for
that not-recommended but people do it anyway path.

[SPIR-V] Handle ASM with multiple outputs (#187128)
Inline ASM that writes to multiple registers is represented as a struct
returning call in LLVM IR. We did not handle this properly, as we
mutated the callsite, but did not correctly retrieve the type during
lowering to SPIR-V. Furthermore, IRTranslator tries to do some clever
things when lowering ASM, which are completely unhelpful to SPIR-V,
which merely wants to pass the original ASM through. This patch
correctly retains the IR type and cleans up the IRTranslator introduced
noise, matching how the SPIRV-LLVM Translator would handle such cases.
There is probably a cleaner reformulation of this to be had when we
rework the entire callsite mutation infra.

I had a failing test case where the log file contains the string being

truncated. I have not debugged why. As soon as I saw the issue, I
figured it was best to skip all the intermediaries, and pass the log

[libc][CndVar] reimplmement conditional variable with FIFO ordering (#192748)
This PR reimplements conditional variable with two different variants:
- futex-based shared condvar with atomic counter for waiters
- queue-based private condvar
Notice that thread-local queue node cannot be reliably accessed in
shared processes, so we cannot use a unified implementation in this
case.
POSIX.1-2024 (Issue 8) added atomicity conditions to conditional
variable:
- The `pthread_cond_broadcast()` function shall, **as a single atomic
operation**, determine which threads, if any, are blocked on the
specified condition variable cond and unblock all of these threads.
- The `pthread_cond_signal()` function shall, as a **single atomic
operation**, determine which threads, if any, are blocked on the
specified condition variable cond and unblock at least one of these
threads.
This means that threads parked after a condvar signal event shall not
steal signals before it. From my read, both implementation fulfills the
requirement but glibc claims that single futex does not provide the
stronger ordering needed by its users hence switched to a rotational
queue, to fulfill the requirements mentioned in
https://sourceware.org/bugzilla/show_bug.cgi?id=13165. As in a single
futex, the lock acquisition do not happen in order and hence when a
spurious wakeup happen, later waiters may "steal" the signal. However
musl's shared implementation and bionic's whole implementation and
Rust's std condvar still stick to a signal-futex+accounting data style.
Musl's private condvar and this implementation are even stronger in the
sense that not only the queue is decided as an atomic event, the mutex
acquisition also happens in baton-passing style.
Our implementation is different from musl in the sense that we have done
some spin attempts instead of always do futex syscall to requeue threads
(with a new requeued state added). This gives a chance for the
signal/waiter to stay in fast path if the queue is really small. Based
on the microbenchmark, this implementation is generally more performant.
We also abuse the `RawMutex`'s LOCKED state as "waiting for its turn".
One caveat we can see from the benchmark
(https://github.com/SchrodingerZhu/condvar-benchmark) is that strict
FIFO condvar is not that good if users are maintain the order on
themselves as in `turn_ring`, because many threads may just wake up
first only see it is not its turn while blocking the real thread in
turn. However, a semaphore or other synchronization primitives would be
more suitable in those cases. Even though in benchmark like
`turn_ring/broadcast_stress` made this code perform badly (but still
similar to musl anyway), they are not really the correct usage. In other
cases, we are always close to the fastest while providing a stronger
FIFO semantic.
TODO in future commit:
- support pthread cancellation. Ideally we should block cancellation
when signal is consumed and add cancellation callback for checking
illegibility.
- think about stronger ordering semantic in shared case (?)

[lldb/test] Fix shared library symlinks for remote testing (#189177)
When running tests on a remote device, framework convenience symlinks
created by test Makefiles (e.g. `$(BUILDDIR)/Framework` pointing to
`$(BUILDDIR)/Framework.framework/Framework`) cause launch failures.
`Platform::Install` recreates these as symlinks on the remote device
pointing to host build paths that don't exist, resulting in "No such
file or directory" from dyld.
This patch changes `LN_SF` in Makefile.rules to strip the common
directory prefix from the symlink source using `patsubst` so it produces
relative symlinks instead of absolute ones.
It also resolve symlinks with `os.path.realpath()` in
`registerSharedLibrariesWithTarget` before registering modules so that
`Platform::Install` sees a regular file and transfers the actual binary
content.

[ELF] Handle INCLUDE like a call stack (#193427)
The lexer maintains a stack of buffers, which allows a construct
started in an INCLUDE'd file to be closed by the parent. This produces
spurious acceptance of malformed scripts (e.g. a bare assignment with
no trailing `;` in the include, terminated by the parent's `;` after
`INCLUDE`) and undefined-behavior span computations in
`readAssignment`'s `commandString` (issue #190376).
Force each INCLUDE to fully parse its own content, similar to a call
stack frame. `ScriptLexer::lex` no longer auto-pops on EOF; the
`buffers` member is gone. `readInclude` takes a `function_ref<void()>`
callback, and the four call sites (top-level, SECTIONS, output
section, MEMORY) pass a context-appropriate parser.
With this, each buffer contains complete parser structures by
construction, so the `[oldS, curTok)` pointer range in
`readAssignment` no longer needs a guard.

[ScheduleDAG] Avoid duplicate worklist entries in ComputeDepth/ComputeHeight. NFC (#192023)
The old loop pushed every not-current predecessor in one sweep, so on
diamond-shaped DAGs a predecessor could be pushed while still on the
stack. Measured on clang -O2 -c sqlite3.i with the old algorithm
instrumented: ComputeDepth had 10.8% duplicate pushes (21.4% of calls
hit the issue).
Rewrite as an iterative post-order DFS that pushes one predecessor at a
time and breaks.

The wide <N x i1> -> iN fallback in performBitcastCombine hardcoded
v16i1/i16 partial masks for every chunk. That is only valid for
16-lane chunks and can crash for cases such as v32i16, where each
concat operand is v8i16 and the partial mask should be v8i1/i8.
Derive the per-chunk mask and integer types from the actual concat
operand type when reconstructing the final scalar bitmask.

Its looks like you're adding new instrumentation/entry points to ASAN -
can you make it conditional so it doesn't affect the test?

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

Reland: [LowerTypeTests] Add debug info to jump table entries (#193670)
When Control Flow Integrity (CFI) is enabled, jump tables are used to
redirect indirect calls. Previously, these jump table entries lacked
debug information, making it difficult for profilers and debuggers to
attribute execution time correctly.
Now stack trace, when stopped on jump table entry will looks like this:
```
#0: __ubsan_check_cfi_icall_jt at sanitizer/ubsan_interface.h:0
#1: c::c() (.cfi_jt) at sanitizer/ubsan_interface.h:0:0
#2: .cfi.jumptable.81 at sanitizer/ubsan_interface.h:0:0
```
This is reland of #192736, reverted with #193663.
This version don't update debug info for "Cross-DSO CFI" mode.

Currently we don't handle any of illegal promoted fixed vectors for

However some of operators are split and some are scalarized depends on
operator type, in this case we need to split it manually.

[RISCV][MC] Remove tautological CHECK-UNKNOWN disassembly checks (NFC) (#193682)
Many RISC-V MC tests assemble with `--mattr=+v` (or another extension),
then run llvm-objdump on the result *without* `--mattr=`, expecting the
disassembler to print `<unknown>` for every instruction. These
CHECK-UNKNOWN lines only restate the encoded bytes that are already
verified by CHECK-ENCODING from `llvm-mc -show-encoding`, so they do not
add coverage.
Drop the CHECK-UNKNOWN RUN lines and check directives from the affected
tests to reduce noise and make the tests easier to read. The remaining
CHECK-INST / CHECK-ENCODING / CHECK-ERROR coverage is unchanged.
This is a preparatory cleanup that makes the upcoming llvm-objdump
per-region disassembly change (using ISA mapping symbols #193448) easier
to review.

This PR moves `MergeConsecutiveExtractSlice` from `MergeConsecutiveInsertExtractSlicePatterns.cpp` to `FoldTensorSubsetOps.cpp`, and removes the duplicate `MergeConsecutiveInsertSlice` pattern in favor of `InsertSliceOfInsertSliceFolder`, which already exists in `FoldTensorSubsetOps.cpp` and provides equivalent functionality with greater stability. Since the merge-related patterns have been fully migrated out, `MergeConsecutiveInsertExtractSlicePatterns.cpp` is renamed to `DropRedundantRankExpansionPatterns.cpp` to better reflect its remaining responsibilities.

[lldb] Remove trailing newlines from AppendErrorWithFormat calls (part 3) (#193527)
Follow up to #193168.
This call adds a newline if there isn't one. Changing these will
eventually let us always add a newline, which is in line with
the other methods on CommandReturnObject.
This is a small part of calls found with:
* VSCode search for
`(\.AppendErrorWithFormat\(([\s\r\n]+)?"(?:(?:\\.|[^"\\])*))\\n"` and
replace with `$1"`.
* Asserting that the last character of the format string is not a
newline.
* Manual inspection.

[LLD][MinGW] Introduce --native-def argument (#193598)
This is the MinGW counterpart of -defarm64native.
When --native-def is not specified, pass the input def file as
-defarm64native on the ARM64X target as well. This reflects the most
common intent when providing a def file for ARM64X and, since the
regular def file is already passed as an input file, it feels consistent
to allow a proper build without requiring additional arguments. This can
be overridden by passing an empty value with --native-def= if using only
the EC def file is desired.

When foldICmpDivConstant encounters a signedness mismatch between the

out. This patch allows it to proceed by checking whether the sdiv's
dividend is known non-negative (via assumes/known bits) and the divisor
is a positive constant. In that case, sdiv is equivalent to udiv, so we
set DivIsSigned=false and let the existing udiv folding handle the rest.

[AArch64] Fix `shufflevector` miscompilation on `aarch64_be` (#193076)
A function like
```llvm
define <4 x i16> @xtn_shuffle_even_v8i16(<8 x i16> %a) {
entry:
%r = shufflevector <8 x i16> %a, <8 x i16> poison, <4 x i32> <i32 0, i32 2, i32 4, i32 6>
ret <4 x i16> %r
}
```
will use the `xtn` instruction, which for each 32-bit vector element
keeps only the lower 16 bits, so effectively this is a truncation.
However, if the vector actually has 16-bit elements, then the conversion
from a shuffle to a truncation is only valid on LE, not on BE. On BE,
`uzp1` should be used instead. So this PR moves some logic to right
after a check for LE, so that BE does not miscompile.
I filed this as an issue on `rust-lang-rust` as
https://github.com/rust-lang/rust/issues/155459, and we had some
discussion at [#t-libs/stdarch > `simd_shuffle!` behaves
strangely on

[DA] Remove monotonicity-related code and tests (#193697)
The concept of monotonicity was introduced in #162280 to abstract the
assumptions used in dependence tests. However, for the ZIV / SIV / RDIV
tests, this concept is excessive and not meaningful. For the MIV tests,
I believe such a concept is necessary, but since we have decided to
disable the Banerjee MIV test for now (see #174733), monotonicity has
effectively become a maintenance burden. Let's clean it for the time
being and reintroduce it only when we truly need it.

For C++17 (clang's default standard) this test passes fine. For C++20 or

To fix this I've added a --std=c++17 to the original run line,

[ISel][AArch64] Add CodeGen support for partial sub reductions. (#186809)
Sub-only (partial) reductions are transformed by the LoopVectorizer to
add-reductions with a scalar sub in the middle block. When there is a
sub-reduction in a chain that has both adds and subs, the resulting
partial reduction with the negation/sub is expanded. This PR improves
codegen of such operations to make use of the [USF]MLSLB/T instructions.

[LV] Factor out VF-independent code from cost model (NFC). (#192426)
LoopVectorizationCostModel currently contains state and helpers to deal
with both VF-dependent and independent aspects of cost modeling.
Some of the state it tracks is per-VF, other state is shared across all
VFs.
This patch tries to factor out most of the VF-independent state +
functions to a new class, to try to more clearly separate those aspects,
and make it easier to reason about what decisions are independent of
VF-specific costs.

[NFC][LLVM] Simplify IIT encoding for scalable vectors (#191737)
Currently, scalable vectors are represented as an `IIT_SCALABLE_VEC`
token in the IIT info table, followed by a IIT encoding for the vector.
This requires remembering the last token seen when decoding the IIT
table and passing that into the recursive call to decode the vector.
Instead, change the representation to use:
```
IIT_V<Size>, IIT_SCALABLE_VEC (optional), Element Type
```
This allows decoding the scalable vector type without having to pass the
last token seen in `DecodeIITType` calls.

[mlir][IntegerRangeAnalysis] Don't unsoundly update constant lattice (#193546)
Fixes #119045
Integer range analysis tried to be clever and update the constant value
lattice when it inferred something to be a constant. However, this
caused correctness issues, because the integer range analysis can go
from "constant" to "not a constant" once more control edges are
analyzed, but the constant value lattice is used by dead code
elimination to skip branches ... including those that might prove that
the conditional for the branch isn't actually a constant.
Unlike in my ancient attempt at a fix, the solution is just to stop
trying to be clever.
This change required loading the constant propagation analysis in
-arith-unsigned-when-equivalent to keep tests working (which should have
been loaded anyway to make the dead code analysis work correctly).

[LangRef] Make volatile loads non-willreturn (#192992)
We currently define that volatile stores are not willreturn (i.e. they
may trap). However, volatile loads are willreturn.
I think that we should align these semantics to say that volatile
operations are always non-willreturn. There's two motivations for this:
* N3128 (part of C23) clarifies the intended meaning of "undefined
behavior" to not allow backwards propagation of UB across certain
observable side-effects, including all volatile operations. This only
made it into the standard as a non-normative note, so complying with
this is not *strictly* necessary for conformance. However, I don't think
there is a strong reason not to follow the recommendation.
* This gives a well-defined (if not very ergonomic) way to interact with
potentially trapping memory.

[AMDGPU] misched: avoid subregister dependencies (#140255)
There are some VOP3P instructions which operate on packed values
and can be configured (op_sel/op_sel_hi) to only use one of the values.
This patch adapts the scheduling dependencies so that a write to vgpr3,
for example, is not a data dependency for a read from vgpr2_vgpr3 in
case only vgpr2 is actually used.

accessing globals) because it needs a load from the GOT. Then select mov
for the G_GLOBAL_VALUE to do that load.

[Lit][NFC] Refactor shell environment functionality and in-process builtins from TestRunner.py into new modules (Reopened) (#177358)
This is a fresh PR for https://github.com/llvm/llvm-project/pull/176761,
reopening after my rebasing error.
Original description:
This is the first in a series of PRs reworking Lit's handling of
in-process builtins to be run as part of command pipelines, and to
enable users to provide new in-process builtins via Lit's configuration.
The full series of patches can be found here:
https://github.com/BStott6/llvm-project/tree/lit-inproc-builtins.
This work is required for the test daemonization project:
https://discourse.llvm.org/t//88612/9
This PR moves the shell environment functionality and existing
in-process builtins from TestRunner.py into new modules. This is
important not just for organizational purposes but also because,
eventually, user defined in-process builtins will need to be able to
import items from these modules, but these cannot import TestRunner as
this would result in a dependency cycle.

[flang] Ignore -fno-realloc-lhs for polymorphic allocatable LHS with warning (#192697)
When -fno-realloc-lhs is specified and the LHS of an assignment is a
polymorphic allocatable (class(*) or class(T)), reallocation semantics
are required by the Fortran 2003 standard for dynamic type tracking and
cannot be safely skipped. Previously, the compiler generated invalid FIR
in such cases (type mismatch between i32 and
!fir.class<!fir.heap<none>>), causing a compilation error.
With this change, when -fno-realloc-lhs is in effect and a polymorphic
allocatable LHS is detected, the compiler emits a warning that the
option is being ignored for that assignment and proceeds with
reallocation semantics.

Log Message:
-----------
[AMDGPU] Fix s_cselect scc clobber issue (#193498)
The frame index elimination e.g., for S_CSELECT_B32 (which reads SCC)
uses the SCC-preserving S_ADDC_U32+S_BITCMP1_B32+S_BITSET0_B32 sequence
instead of a plain S_ADD_I32, even when the regscavenger reports SCC as
unused due to its backward scan removing the SCC def from the live set.
Root cause: scavengeRegisterBackwards scans backward from MI and calls
LiveRegUnits::stepBackward() on each instruction. stepBackward removes
defs from the live set. When it processes the S_AND_B64 (which defines
SCC) immediately before S_CSELECT_B32, SCC is removed from LiveUnits.
This makes RS->isRegUsed(SCC) return false, so NeedSaveSCC was false
before the fix.
The fix adds MI->readsRegister(SCC) to the NeedSaveSCC condition so the
SCC-preserving ADDC+BITCMP1+BITSET0 sequence is always used when MI
reads SCC, regardless of what the regscavenger reports.

should keep the function call so the programmer can observe the side
effect.

Before
https://github.com/llvm/llvm-project/commit/b9c0e590f1fd4ea37da5c2b9b78d8e715c885f56
switched the C++ status page to a reverse chronological order, it made
sense to avoid wasting vertical space for already-implemented standards.
After that switch, it would make sense however to unfold them by
default.
This is for example why I had opened #61426, because CRTL+F did not show
P0588 on the status page[^1]. But not just for this paper, I think the
ease of finding papers is a good argument for folding out those tables.
[^1]: together with the fact that other status pages
([example](https://en.cppreference.com/cpp/compiler_support/20)) have
sorted this paper under C++20 rather than C++11.

[mlir][vector] Generalize castAwayContractionLeadingOneDim (#187312)
This PR generalizes castAwayContractionLeadingOneDim to allow
accumulators with rank 1 to be matched.
With this generalization we allow the following contractions:
```
%c = vector.contract {
indexing_maps = [
affine_map<(d0, d1) -> (d0)>,
affine_map<(d0, d1) -> (d1, d0)>,
affine_map<(d0, d1) -> (d1)>],
iterator_types = ["reduction", "parallel"],
kind = #vector.kind<add>
} %0, %1, %2 : vector<64xf32>, vector<1x64xf32> into vector<1xf32>
```
to be matched and transformed to
```
map = affine_map<(d0) -> (d0)>
map1 = affine_map<(d0) -> ()>
%2 = vector.contract {
indexing_maps = [#map, #map, #map1],
iterator_types = ["reduction"],
kind = #vector.kind<add>
} %arg0, %0, %1 : vector<64xf32>, vector<64xf32> into f32
```
I noticed the following chain of transformations in IREE which led me to
this fix:
```
%23 = vector.shape_cast %22 : vector<64xf32> to vector<1x64xf32>
%24 = vector.contract {indexing_maps = [affine_map<(d0, d1) -> (d0)>, affine_map<(d0, d1) -> (d1, d0)>, affine_map<(d0, d1) -> (d1)>], iterator_types = ["reduction", "parallel"], kind = #vector.kind<add>} %14, %23, %cst_0 : vector<64xf32>, vector<1x64xf32> into vector<1xf32>
```
ContractionOpToOuterProductOpLowering
```
%23 = vector.shape_cast %22 : vector<64xf32> to vector<1x64xf32>
// transpose rhs
%24 = vector.transpose %23, [1, 0] : vector<1x64xf32> to vector<64x1xf32>
```
FoldTransposeShapeCast
```
%21 = vector.shape_cast %20 : vector<64xf32> to vector<64x1xf32>
```
With this generalization, `castAwayContractionLeadingOneDim`'s will be
transformed to a reduction during ContractionOpLowering.

[OpenMP][OMPIRBuilder] Convert cmpxchg memory order to C ABI constants (#193536)
`EmitAtomicCompareExchangeLibcall` passed LLVM AtomicOrdering enum
values directly as the success/failure ordering arguments to
`__atomic_compare_exchange`. However, the C ABI expects the `__ATOMIC_*`
constants instead.
`EmitAtomicLoadLibcall` and `EmitAtomicStoreLibcall` already use
`toCABI()` for this conversion. Apply the same conversion in
`EmitAtomicCompareExchangeLibcall`.
This PR is a reland of #191857 which was closed incorrectly due to

[TySan] Fix size type mismatch in instrumentMemInst for 32-bit targets (#191601)
The outlined instrumentation path in instrumentMemInst passes Size
directly to the __tysan_instrument_mem_inst runtime call, which declares
its size parameter as uint64_t (i64). On 32-bit targets, Size is
IntptrTy (i32) for allocas and byval arguments, causing an assertion:
Calling a function with a bad signature!
Add CreateZExtOrTrunc to widen Size to U64Ty before the call. This is a
no-op on 64-bit targets where IntptrTy is already i64.

[DAGCombiner] Fold bswap of single-byte-known-nonzero value to a shift (#193473)
When computeKnownBits proves that a bswap operand has at most one byte
of possibly-nonzero bits at a known byte-aligned position, the bswap is
equivalent to a shift that moves that byte to the mirror position. This
is a producer-side known-bits rule; it fires in visitBSWAP regardless
of how the narrow-value provenance was established, covering shapes
such as
bswap(and X, 0xFF)
bswap(and X, 0xFF00) ; all byte positions
bswap(zext i8 X to iN)
bswap(zext i16 X to i64)
Motivation. While investigating a RISCV codegen regression under
-combiner-topological-sorting (bswap-shift.ll), I traced the root cause
to the existing consumer-side rule in
TargetLowering::SimplifyDemandedBits
for ISD::BSWAP: when a consumer demands only one byte of the bswap
result, that rule rewrites the inner bswap as a shift. Under topological
(producer-first) worklist ordering, this rewrite fires on the inner
bswap of bswap(srl(bswap X, 8)) before visitBSWAP's syntactic pattern
bswap(srl X, 8) -> (bswap X) shl 8 can collapse the whole chain, so
the outer bswap is stranded as bswap(and(X, MASK)), which no existing
combine recognizes.
The new rule is orthogonal: it matches when the operand's known bits
(rather than the consumer's demand) characterize a single-byte value,
so it closes the gap in both topological and non-topological modes. It
also captures genuinely new missed optimizations that are independent
of the ordering problem: bswap(zext i8 -> i64) previously emitted
zext.b + rev8 on RISCV+zbb and is now a single slli 56.
Placement choice. The rule is a natural dual of the existing consumer-
side rule in TargetLowering::SimplifyDemandedBits for ISD::BSWAP; the
needed information (computeKnownBits of the source) is readily
available there. I prototyped that placement and found it strictly
weaker: SimplifyDemandedBits runs later in the pipeline, typically
after integer type promotion, so a rewrite of a native i16 bswap fires
only after the value has been widened to i64 and the outer i16->i64
promotion shifts block further simplification. Placing the rule in
visitBSWAP fires pre-type-legalize on native i16/i32 values, letting
the resulting shift compose cleanly with downstream combines. A
comment in visitBSWAP cross-references the dual rule for future
readers.
Potential extension. The same logic can also be added to
TargetLowering::SimplifyDemandedBits (as a second check after the
existing one-byte-demanded rule, using computeKnownBits(Src) rather
than the demand-restricted Known2) for cases where visitBSWAP is not
reached via the combiner worklist but the bswap is recursed into by a
parent's demand analysis. I did not include that duplicate here
because no pre-existing test exercises such a path; the visitBSWAP
placement alone closes every case I found.

[libc] Honor per-test timeout in lit test format (#193772)
The custom LibcTest format did not pass litConfig.maxIndividualTestTime

hanging tests like fdiv_test on AMDGPU blocked the entire suite until
the buildbot watchdog killed the process after 1200s.
Added timeout propagation and handling of ExecuteCommandTimeoutException
to return lit.Test.TIMEOUT. This follows the same pattern used by the
GoogleTest format in googletest.py.

[RISCV][GlobalISel] Add intial support for inline asm (#193314)
This patch adds the (almost) minimal changes to support inline assembly
in the RISC-V GlobalISel backend.
The tests are mostly from
`llvm/test/CodeGen/AArch64/GlobalISel/irtranslator-inline-asm.ll` but
sadly not all test could be taken. I am planning to address the
remaining tests in later PRs.
The motivation for the PR was a fallback to SelectionDAG when compiling
libc. The motivating case can be seen in the test
`test_input_register_pointer`. That is also the reason for the small
changes in `RISCVInstructionSelector::selectCopy`.

Reland "[Lit][NFC] Refactor shell environment functionality and in-process builtins from TestRunner.py into new modules" (#193759)
Fixed version of #177358 which accidentally removed an import.
This is the first in a series of PRs reworking Lit's handling of
in-process builtins to be run as part of command pipelines, and to
enable users to provide new in-process builtins via Lit's configuration.
The full series of patches can be found here:
https://github.com/BStott6/llvm-project/tree/lit-inproc-builtins.
This work is required for the test daemonization project:
https://discourse.llvm.org/t//88612/9
This PR moves the shell environment functionality and existing
in-process builtins from TestRunner.py into new modules. This is
important not just for organizational purposes but also because,
eventually, user defined in-process builtins will need to be able to
import items from these modules, but these cannot import TestRunner as
this would result in a dependency cycle.

The previous PR #173730 only addressed the **intrinsics**
`@llvm.sinh.f64` etc, which does not have effects on the C program
compiled without `-fno-math-errno`.
I validated the optimization by `clang -O2`.

[flang] Support polymorphic types in conditional expressions (#192684)
Add lowering support for polymorphic (`CLASS(T)`) conditional
expressions.
`ConditionalExpr::GetType()` now checks both branches and returns the
polymorphic type if either is polymorphic (F2023 10.1.4(7)). In
lowering, polymorphic conditionals use `fir::ClassType` instead of
`fir::BoxType` for the allocatable temporary so that dynamic type info
is preserved through `hlfir.assign` realloc.
Covers scalar, array, and mixed `TYPE(T)`/`CLASS(T)` operands. Unlimited
polymorphic `CLASS(*)` does not have a declared type, and is therefore
rejected in semantics. LIT tests for lowering and semantics have been
updated.

`lldb.frame` is a Python convenience variable that resolves to `None`

`AttributeError` before the run locker check is ever reached. Use
`lldb.target` instead, which is always valid and properly exercises the
run locker path.

[ConstantRange] Expand makeAllowedICmpRegion to use samesign to give tighter range (#174355)
After the addition of samesign then instcombine correctly transforms
unsigned greater than to use it if it can prove that value is greater
than zero and then removes the assume that allowed it to prove that. For
example:
```
define i8 @remove_for_samesign(i8 %x) {
%gt = icmp sgt i8 %x, 10
call void @llvm.assume(i1 %gt)
%gt.zero = icmp sge i8 %x, 0
call void @llvm.assume(i1 %gt.zero)
ret i8 %x
}
```
Is optimized to:
```
define i8 @remove_for_samesign(i8 %x) {
%gt= icmp samesign ugt i8 [[X:%.*]], 10
call void @llvm.assume(i1 %gt)
ret i8 %x
}
```
This leads to a wrong range being returned from computeConstantRange
because it doesn't look at samesign when constructing a range from
assumes, this patch fixes that.

[HLSL] Add codegen for accessing resource members of a struct (2nd merge attempt) (#193584)
Any expression that accesses a resource or resource array member of a global struct instance must be during codegen replaced by an access of the corresponding implicit global resource variable.
When codegen encounters a `MemberExpr` of a resource type, it traverses the AST to locate the parent struct declaration, building the expected global resource variable name along the way. If the parent declaration is a non-static global struct instance, codegen searches its `HLSLAssociatedResourceDeclAttr` attributes to locate the matching global resource variable and then generates IR code to access the resource global in place of the member access.
Fixes #182989
This is the second try to land this. The [first one](https://github.com/llvm/llvm-project/pull/187127)collided with #188792 and both PRs had to be reverted. No updates needed to this change. I synced with @inbelic and we agreed

Reland #2 "[STLExtras] Add a template for detecting whether a type has an equality comparison operator" (#177415)
Reland PR #176893 which was an attempt to reland PR #176429.
Fix:
There was a test case asserting that for types `StructA` `StructB` where
`operator==(const StructB &, const StructA &)` is defined,
`has_equality_comparison_v<StructA, StructB>` is false because the
arguments are the wrong way around. However, in C++20, operator overload
resolution was changed so that for reflexive comparison operators `==`
and `!=` if a candidate exists with the arguments swapped then this will
be used. This means the test case failed when compiled with C++20. That
check was simply removed in this version.

[flang] Route elemental CHARACTER MIN/MAX OPTIONAL cases through custom lowering (#191244)
Follow-up to #189464.
Elemental CHARACTER MIN/MAX with dynamically optional arguments was
bypassing the custom optional-handling path and could lower incorrectly.
This change routes those cases through `genCustomIntrinsicRefCore` so
they hit the existing TODO instead of producing bad code. It also
unwraps sequence types before checking `fir::isa_char`, so the same TODO
is triggered for elemental calls as well as scalar ones, and adds a
negative test for the diagnostic.

Remove unused parameter; NFC (#193767)
As part of removing delayed typo handling in
9eef4d1c5fa6b1bcbbe675c14ca8301d5d346f7b, the KeywordReplacement
parameter ended up being unused, so this patch removes it and adjusts
the callers. This issue was discovered by a downstream static analysis
scan.
It is an NFC change because the callers of the function were looking for
a sentinel return value to determine whether they needed to call
UnconsumeToken on that parameter, but those calls cannot be reached
because the sentinel return value cannot be produced any longer.

[lit] Fix `progress-bar.py` flaky test (#193741)
The `lit` progress-bar test was checking for exact progress-bar text
like `0.. 10.. 20.. 30.. 40..`, but that output is not stable from run
to run.
The progress bar is based on timing estimates, including saved timings
from earlier runs, so small timing differences can change which numbers
get printed.
That made the test flaky: `FileCheck` could match the wrong `Testing:`
line
and then fail later, even though the actual test failures were correct.
Relax the test to verify ordering instead of exact progress-bar
contents. The updated checks assert that the test header is printed,
that
each failing test result is separated by a `Testing:` progress-bar line,
and that the final failed-tests summary lists all expected tests in
order.
This preserves coverage for the simple progress-bar path while removing
dependence on unstable timing-derived percentages.

This expands the set of scalable typed binary intrinsics which can be

provided by clang. Support for the binary ones will follow in a separate
patch.
Note that the lowering quality is terrible, particularly when the libc
entry for the scalar routine doesn't preserve vector registers (e.g.
RISC-V default). This is a functional fix to avoid crashes when trying
to codegen these, nothing more.

createKernelArgArray in CUFGPUToLLVMConversion packed one pointer per

expands each memref into 3 + 2*rank scalar parameters, so the host-side
kernelParams did not match the device kernel signature and
cudaLaunchKernel failed with cudaErrorInvalidValue.
Host-side packing now unpacks each memref descriptor into its scalar
fields (allocatedPtr, alignedPtr, offset, sizes..., strides...),
matching the NVVM ABI. Non-memref operands pass through unchanged.

Add `OMPD_parallel_loop` to `GetLoopDirectives()` in the Flang OpenMP
parser so that the valid OpenMP 5.0 combined construct
`!$omp parallel loop` is recognized as a loop construct.
Previously, the parser failed to match `parallel loop` as a loop
directive. It then fell through to matching `parallel` as a block
construct, leaving `loop` as an unexpected token, producing:
```
error: expected OpenMP construct
!$omp parallel loop
^
```
The directive was already fully defined in OMP.td and handled in the
semantics directive sets, lowering, and MLIR `GenericLoopConversion`
passes. Only the parser set was missing the entry.

Re-apply "[AMDGPU][Scheduler] Use MIR-level rematerializer in rematerialization stage (#189491)" (#192443)
This fixes compilation errors in EXPENSIVE_CHECKS introduced by
[be62f27](https://github.com/llvm/llvm-project/commit/be62f270fd01e8c526f1e37df74ff1061e360dab).
This is solved by moving the EXPENSIVE_CHECKS block at its original
caller's site so that the data it reads is available.
Original PR description below.
---
This makes the scheduler's rematerialization stage use the
target-independent rematerializer. Previosuly duplicate logic is
deleted, and restrictions are put in place in the stage so that the same
cosntraints 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.

With some recent refactorings, these builds are almost entirely

to get the total wall-time down.
This wouldn't have as big of an advantage if we were using the just
built base image, but should still be wall-time advantagous even if we
go back to doing that when relevant.

[CIR] Handle negative offsets in pointer constants (#193624)
When a negative offset was used as an index into a global array as part
of a global pointer initialization, CIR was hitting an unreachable
marker while trying to construct a GlobalView attribute to describe the
pointer initialization. Although this sort of negative offset is UB,
Clang allows it, so we want to produce the same results via CIR.

[CIR] Implement handling for destroying delete (#193607)
This adds CIR handling for destroying delete calls. The basic support
for deleting objects via virtual and non-virtual delete calls was
already in place. All that was needed was to add the function to emit
these calls when a destroying operator delete was encountered in
`emitCXXDeleteExpr` and to add the code to add the destroying delete tag
parameter when it is needed.
Note, classic codegen elides the destroying delete tag parameter for the
new test case because it represents an empty class. That will be handled
as part of ABI lowering in CIR, but it is not yet implemented.

[CIR] Allow multi-block ctor regions on GlobalOp (#193596)
C++14 variable templates with non-constexpr constructors (e.g., `static
const Foo<N> x{}` where `Foo()` is not constexpr) crash CIR codegen
with:
```
'cir.global' op region #0 ('ctorRegion') failed to verify
constraint: region with at most 1 blocks
```
The problem is that `GlobalOp`'s `ctorRegion` is declared as
`MaxSizedRegion<1>`, but when exceptions are enabled, `emitAggExpr` can
create additional blocks in the ctor region for EH cleanup scaffolding
(unreachable/trap terminators). These extra blocks are dead code —
`LoweringPrepare` already discards them when it moves the ctor region
into `__cxx_global_var_init`.
This patch relaxes the constraint to `AnyRegion` and replaces the
`llvm_unreachable("Multiple blocks NYI")` in the static-local guard path
with an assert (that path will be reworked by #193576).

[CIR] Add restrict→noalias on non-builtin pointer params (#191483)
Map `restrict`-qualified pointer parameters to `noalias`, skipping
builtins (e.g. `printf`) where OGCG doesn't apply it. OGCG only adds
`noalias` from `restrict` through its calling-convention lowering path,
which builtins bypass, so the `!fd->getBuiltinID()` guard keeps CIR in
line.
`constructFunctionArgumentAttributes` now takes `targetDecl` so it can
look up `ParmVarDecl` qualifiers.
Updated `asm-label-inline-builtins.c` checks to reflect the new
`noalias` on the non-builtin `__vfprintf_chkieee128` call. New test:
`restrict-noalias.c` (CIR / LLVM / OGCG).

[lldb] Speculative fix for crash in Function::GetCallEdges() (#193636)
Replace the unprotected union+bool lazy resolution in DirectCallEdge
with `std::call_once`/`std::once_flag`.
Multiple threads can call `GetCallee` on the same edge concurrently and
the old code had no synchronization on the union discriminator or its
contents. This could lead to a corrupted pointer that would explain the
crash we're observing sporadically.

Remove the getLinkerVersion checks that gated default enablement of

AArch64 Darwin targets.
The linker support for these stubs was added a long time ago, so the
version checks are no longer necessary. Additionally, getLinkerVersion
returns the version of the linker that was used to build clang, which
can differ from the linker actually used at invocation time, making the
check unreliable.

[MLIR][Mem2Reg] Ensure dominance of default value in regions (#193708)
When we promote an allocation, and a default value for a load from an
uninitialized slot is required, this value used to get inserted in the
same block as the allocation. However, in some cases, the default value
needs to be available in the predecessor blocks so that they can pass it
to the block of the allocation as an argument. For example, this is the
case for loops containing an allocation where the promoted value will
become and IV.
Make sure the default value is always available to all blocks by
creating it in the entry block of the region.
For reference, this is what used to be the output for the test. Note the
use of `%1`.

[PreISelIntrinsicLowering] Use index type for index in intrinsic expansion (#193807)
We'd chosen intptr type for the binary in review, but on reflection the
index type is probably a conceptually better fit. On riscv, these are
going to be the same, so it's purely a conceptual issue.
For the unary case, this is an actual change since we were using i64
unconditionally. This improves codegen for RV32 by avoiding the need for expensive legalization of i64 expressions for the IV.

[mlir][canonicalize] Add filter-dialects option (#193041)
Add a new `filter-dialects` list option to the canonicalize pass. When
provided, only canonicalization patterns from the listed dialects are
collected, and the named dialects are force-loaded via
getDependentDialects.
Loading flow: the Canonicalizer's getDependentDialects override calls
`registry.addDialectToPreload(name)` for each filter-dialect name, which
records the name in a new `dialectsToPreload` list on DialectRegistry.
The PassManager's pipeline-init then calls
`dependentDialects.preloadSelectDialects(ctx, emitError)`, which loads
each preload entry via `context->getOrLoadDialect(name)` — the real
allocator is resolved from the context's own registry (registered by
the tool) and the dialect is loaded before multi-threaded execution
begins. If a requested dialect has no registration in the context, a
diagnostic `"can't load dialect '<name>': missing registration?"` is
emitted.
DialectRegistry API changes:
- New `addDialectToPreload(StringRef)` method: records a dialect name
that should be loaded into the MLIRContext but whose allocator lives
in the context's own registry. The registry itself does not load the
dialect — it just carries the request.
- New `preloadSelectDialects(MLIRContext *,
function_ref<InFlightDiagnostic()> = {})`
method: loads every preload-registered dialect into the context,
returning failure (and optionally emitting a diagnostic) for the
first name that cannot be resolved.
- `getDialectNames()` is split into two accessors:
* `getRegisteredDialectNames()` — names of allocator-backed entries
from the registry map.
* `getDialectsToPreload()` — preload-only entries added via
`addDialectToPreload(StringRef)`.

call sub((x > 10 ? a : x > 5 ? b : c))
call sub((flag ? a : .NIL.))
- Add ConditionalArg and ConditionalArgTail parse tree nodes
- Add Nil empty class for .NIL. representation
- Add ConditionalArg as a new alternative in ActualArg
- Add parser rules for conditional-arg, consequent, and chained branches
- Add unparse support for round-trip printing
- Add dump-parse-tree and FeatureList support
- Add parser tests covering simple, multi-branch, .NIL., BOZ, NULL(),
keyword arguments, and module procedure cases

[Clang] Fix sret AS for non-trivial-copy returns. (#186275)
classifyReturnType used getAllocaAddrSpace() for sret, which is wrong
on targets like AMDGPU where alloca lives in addrspace(5). For types
with deleted copy/move constructors, there is no way to construct into
a temp and copy out — the sret pointer must point directly to the caller's
destination in the default address space.
Add a target hook getSRetAddrSpace() so AMDGPU can return LangAS::Default
for non-register-passable types.

[lldb/test] Fix TestOSIndSYM for Darwin embedded platforms (#193839)
The test used CreateTarget(None) and relied on the attach to discover
the executable and load the dSYM. On remote platforms this doesn't find
the local dSYM, so the OS plugin never loads. Switch to
CreateTarget(executable) so the dSYM Python module is loaded before
attach.
Also split the test into two methods: test_python_os_plugin uses
spawn+attach which works both locally and on real remote platforms,
while test_python_os_plugin_remote simulates remote debugging by
manually spawning debugserver and is skipped on embedded platforms where
this setup conflicts with lldb-platform.

[flang][cuda] Preserve fir.rebox captured by cuf.kernel in SimplifyArrayCoorOp (#193837)
SimplifyArrayCoorOp folds fir.rebox → fir.array_coor by rewriting the
array_coor to consume the rebox's source box directly. This is unsafe
when the array_coor is inside a cuf.kernel and the rebox is not: in CUF,
a rebox of a device-attributed value (e.g. a dummy with cuf.data_attr =
device) is the op whose lowering copies the descriptor into
GPU-accessible memory. Folding it out skips the copy, so the kernel
dereferences a host-side descriptor on the device, causing
cudaErrorIllegalAddress (or cudaErrorUnknown on H100 under ATS).
The pattern already guards this hazard for OpenACC via
ACC_COMPUTE_AND_DATA_CONSTRUCT_OPS / ACC_DATA_ENTRY_OPS; this change
adds the analogous guard for cuf::KernelOp.

[MachineOutliner] Do not allow debug instructions to affect liveness computations. (#192336)
Because DBG_VALUE precedes the actual definition of a physical register,
considering
these during the liveness updating phase of MachineOutliner was causing
every register
definition to also be marked as a use, which would eventually lead to a
verifier error
when a use without a def was detected.
A MIR testcase for this is present at
https://github.com/CHERIoT-Platform/llvm-project/commit/b71f6d67e338e70a1dc23e15a77805da3e3cd015
but it depends on CHERIoT instructions that are not in LLVM upstream at
present. It's also very senstive to small changes to the input, so I
have not been able to reproduce it on an in-tree target. That said, I
believe this change is small enough that its correctness is verifiable
by inspection.

[CIR] Handle boolean expression as array indexes (#193814)
We were hitting a CIR verification error in some cases when a boolean
expression was used as an index to an array because the GetElementOp
verifier expected the index operand to be a fundamental integer type. To
fix this, I'm updating the emitArraySubscriptExpr to cast index values
to ptrDiffTy, which more closely matches what classic codegen does in
the corrsponding code.
The improved alignment with the classic codegen implementation caused
some minor changes in generated IR that required some tests to be
updated.

Reapply "[clang][modules-driver] Add support for C++ named modules and `import std`" (#193815)
This reverts #193677 and relands #193312.
This adds basic support for explicit C++ named module builds, managed
natively by the Clang driver, including support for use of the Standard
library modules. This follows #187606, which adds the same for Clang
modules.
Current limitations:
- Standard library modules are still compiled to object files instead of
using the provided shared library. (This will be addressed in a
follow-up soon.)
- Caching is not supported yet (but likely to be added during the
upcoming GSoC cycle).
- Importing C++ standard library modules into Clang modules is not
supported (and not expected in the near term).

[CIR] Add coroutine cleanup handling and update co_return semantics (#189281)
This PR adds cleanup handling for coroutine frame destruction. The
cleanup is emitted as a conditional that checks the result of the
`coro.free` builtin, which is used to determine whether the coroutine
frame was heap-allocated, if the returned pointer is null, no
destruction is performed. Additionally, this PR changes how co_return is
represented: previously, it was lowered directly into a branch to the
block containing the final suspend logic, but now a new `cir.coro.body`
operation is introduced to represent the user-written coroutine body.
Inside this region, `cir.co_return` operations mark exits from the
coroutine body and represent structured control flow that transfers
execution to the final suspend point. The lowering of this structured
control flow into explicit branches is deferred to a future PR in the
FlattenCFG pass.

[Clang][CodeGen] Fix sret lifetime marker AS mismatch after #186275 (#193850)
After #186275, the sret address space can differ from the alloca address
space (e.g., AS 0 vs AS 5 on AMDGPU). In CGCall.cpp EmitCall(), when a
discarded-value sret temporary is created, SRetPtr is allocated in the
alloca AS and a lifetime.start is emitted. The pointer is then
addrspacecast'd to match the sret AS, but the CallLifetimeEnd cleanup
was using the addrspacecast'd pointer, triggering an assertion in
EmitLifetimeEnd ("Pointer should be in alloca address space").
Saves the original alloca pointer before the addrspacecast and uses it
for the lifetime-end cleanup.

We began expanding these nodes in #190589 since vp_fadd/vp_fmul/vp_fsub
could be combined into them. Now that these intrinsics are expanded too,
the lowering for these is dead and can be removed.

[clangd] [C++20] [Modules] Introduce persistent cache for clangd built module file (#193883)
Currently clangd lacks a persistent cache for clangd built module file.
It implies that every time a new clangd process starts, or a user close
all tabs and opening all a new tab. Clangd will build all the module
files required. This is a slow process. Especially, the building happens
in the building thread for the opening tab. That is, if the user only
opens a single tab, clangd needs to build all the module file in a
single thread. This is very slow in practice.
As clangd is basically a wrapper for clang, we can't do nothing to speed
the building process actually and the only thing we can do is to
introduce a better cache mechanism.
So everytime the user opens a new tab, now clangd won't try to build all
the needed module file at first but try to see if these module files are
already built and up-to-date. So clangd can try to avoid a lot of time
to rebuilding the same thing.
For details,
now the built module file will live in
<cache-root>/<module-unit-source-name>-<source-hash>/<command-hash>/<module-name>[-<version>].pcm
Here <cache-root> stands for
<path-to-compilation-database>/.cache/clangd/modules or
<user-home>/.cache/clangd/modules
the <source-hash> in <module-unit-source-name>-<source-hash> means the
hash of the path of the corresponding module unit, as we can have
different a.cppm in different directories in a project.
<command-hash> means the hash of the command. As we can produce
different BMI with different command.
Then <module-name>.pcm means the newest BMI. And
<module-name>-<version>.pcm means a CopyOnRead BMI of <module-name>.pcm.
We did this to ease the concurrency management. As now, we can be sure
<module-name>.pcm won't be used by anyone in clangd itself.
TODO: We didn't implement a GC so that cache size may increase
consistently. We will didi that in following patches.
AI assisted.

[IR] Remove pointer arguments from loop.dependence.{war|raw}.mask (#188248)
Passing pointer arguments is quite inconvenient for practical use. These
intrinincs only care about the difference between the address bits of
two pointers, but by taking pointer arguments it is implying they care
about other details of the pointers (such as addrspace, or other pointer
bits).
This metadata is currently not preserved when gathering diff checks in
the loop vectorizer, so requiring pointers makes emitting these
intrinsic more complex (or requires preserving information that is
ultimately unused).

[lldb] Add regression test for stale Symbol pointer crash in statusline (#193854)
Add a test that exercises the code path fixed in
[88f024223cc4](https://github.com/llvm/llvm-project/pull/188377)
("[lldb] Fix stale Symbol pointer crash in statusline after 'target
symbols add'").
The bug: when `target symbols add` is called, `Symtab::AddSymbol()` can
reallocate the underlying `std::vector<Symbol>`, invalidating all
existing `Symbol*` pointers. The statusline caches an
`ExecutionContextRef` containing a `StackID` with a
`SymbolContextScope*` (which can be a `Symbol*`). If a concurrent
statusline redraw occurs between the Symtab reallocation and
`Process::Flush()` (e.g. from a progress event on the event handler
thread), the cached `StackID` matches the old frame via pointer-equal
comparison, and `GetSymbolContext()` dereferences the dangling
`Symbol*`.
The test:
1. Builds a stripped binary and its unstripped counterpart.
2. Runs the stripped binary and stops at a breakpoint in `main`.
3. Enables the statusline (populating the cached `ExecutionContextRef`).
4. Calls `target symbols add` to add debug symbols back.
5. Forces a statusline redraw via terminal resize, which calls
`Redraw(std::nullopt)` using the cached (potentially stale) execution
context.
6. Verifies the statusline still renders correctly.
The dangling pointer is a use-after-free that silently succeeds in
non-sanitizer builds (the freed memory is still accessible). This test
is most effective under AddressSanitizer, which poisons freed memory and
immediately detects the stale access.

[mlir][EmitC] Add tests for arith.max/min float/signed int conversions (#190160)
This patch adds test coverage for the combined `-arith-expand |
-convert-arith-to-emitc` pipeline for selected `arith` max/min operations.
The new tests exercise:
- `arith.maximumf`
- `arith.minimumf`
- `arith.minsi`
- `arith.maxsi`
The intent is not to re-test the individual passes in isolation. Expansion is
already covered in `test/Dialect/Arith/expand-ops.mlir`, and the direct
Arith-to-EmitC lowering is already covered in
`test/Conversion/ArithToEmitC/arith-to-emitc.mlir`. This patch specifically
checks that the combined pipeline produces the expected EmitC operations after
expansion.
For floating-point max/min, the test verifies the expanded form lowers to the
expected sequence of `emitc.cmp`, `emitc.logical_or`, and `emitc.conditional`
operations. For signed integer min/max, it verifies lowering to the expected
`emitc.cmp` and `emitc.conditional` sequence.
The test also documents currently unsupported cases for the combined pipeline:
vector cases are excluded because expansion introduces `arith.cmpf`, and
`ArithToEmitC` does not convert `VectorType`; tensor cases are excluded because
`ArithToEmitC` only lowers scalar `cmpf`.
Assisted-by: Codex (refine tests and comments).
I reviewed all code and tests before submission.

[LV] Simplify live-out extraction for first-order recurrence phis when tail folding (#176108)
The idea is similar to ba40a7bc2e65be86ac23c9cf6038ac085dda77eb. Due to
tail folding, the recurrence vector in the final iteration may contain
only a single active element, making it impossible to extract the
penultimate active element. This patch instead directly extracts the
last active element from the vector produced by splicing the recurrence
phi and the previous value, without needing to select which value to
extract based on the number of active lanes.

[libc] Honour LIBC_GPU_TEST_JOBS in lit test runs (#193797)
Under CTest, LIBC_GPU_TEST_JOBS controlled a ninja job pool that limited
concurrent GPU test processes. The AMD GPU buildbot sets this to 4 to
avoid overloading the GPU driver.
When running tests via lit, this constraint was lost because lit uses
its own -j flag (defaulting to nproc, or set to 64 on the AMD bot via
LLVM_LIT_ARGS). All GPU loader processes launched simultaneously,
leading to hangs from GPU resource exhaustion.
Propagated LIBC_GPU_TEST_JOBS into the lit site config as a parallelism
group so lit throttles GPU test concurrency independently of the global
-j setting.

[flang][debug] generate llvm.fake.use for arguments at -g and O0 (#187044)
Fix for https://github.com/llvm/llvm-project/issues/185432.
This patch extends the lifetime of procedure dummy arguments using llvm.fake.use
so that they are accessible in debugger during the whole lifetime of the function.
This is done by:
- adding a new fir.fake_use operation and emitting it in AddDebugInfo.cpp for
dummy arguments at the end of the procedure scope.
- lower this new fir.fake_use to the llvm.fake.use intrinsic.
This is done under -g at O0 only to avoid pessimizing the generated code when
optimizations are requested.

[lldb][test] Remove full stop from expected error messages (#193748)
I am about to update a bunch of uses of AppendErrorWithFormat to not
have a full stop at the end, to confirm to
https://llvm.org/docs/CodingStandards.html#error-and-warning-messages.
Reviewing all those changes is going to be difficult so I am updating
the tests first and then we can land the other changes in batches
(because the tests will continue to pass as we do that).
Note that I have only run the test suite on Linux AArch64, so there are
probably more that need to be updated. We will catch those in CI or
post-commit.

I found these with:
* Find `(\.AppendErrorWithFormat\(([\s\r\n]+)?"(?:(?:\\.|[^"\\])*))\."`
and replace with `$1"` using Visual Studio Code.
* Putting a call to `validate_diagnostic` in `AppendErrorWithFormat`.
* Manual inspection.
Note that this change *does not* include a call to `validate_diagnostic`
because I do not know what's going to crash on platforms that I haven't
tested on.

[mlir][math] Use APFloat::SemanticsToEnum in constant folding (#193914)
Refactor constant folding in the Math dialect to use APFloat::SemanticsToEnum() instead of getSizeInBits() when checking
floating-point semantics. Inferring semantics from bitwidth is fragile: different formats may share the same bit width but have distinct semantics, leading to incorrect dispatch. SemanticsToEnum() matches on the exact semantics descriptor, making the intent explicit and ensuring correct dispatch.

[lldb][Linux] Read memory protection keys for memory regions (#182246)
Memory protection keys
(https://docs.kernel.org/core-api/protection-keys.html) are implemented
using two things:
* A key value attached to each page table entry.
* A set of permissions stored somewhere else (in a register on AArch64
and X86), which is indexed into by that protection key.
So far I have updated LLDB to show the permissions part on AArch64 Linux
by reading the por register. Now I am adding the ability to see which
key each memory region is using.
```
(lldb) memory region --all
[0x0000000000000000-0x000aaaae3b140000) ---
[0x000aaaae3b140000-0x000aaaae3b150000) r-x /tmp/test_lldb/linux/aarch64/permission_overlay/2/TestAArch64LinuxPOE/a.out PT_LOAD[0]
protection key: 0
[0x000aaaae3b150000-0x000aaaae3b160000) rw- /tmp/test_lldb/linux/aarch64/permission_overlay/2/TestAArch64LinuxPOE/a.out
protection key: 0
```
The key is parsed from the /proc/.../smaps file, and so will only be
present for live processes, not core files.
This is sent as part of the qMemoryRegionInfo response as a new
"protection-key" key. As far as I know "memory protection keys" are
Linux specific, but I don't know of a good generic name for it, so I've
copied what smaps calls it.
I have updated the "memory region" command to show this key. A lot of
the time this will be the default 0 key. I considered hiding this, but
decided that for this initial support it's better to be explicit and
verbose (this also prevents a Linux specific detail being added to the top level
memory region command).
I have not added protection keys to the SBAPI because:
* I don't know of a specific need for them.
* They are very easy to add if someone does want them later (just a
HasProtectionKey and GetProtectionKey).
* Arm's POE2
(https://developer.arm.com/community/arm-community-blogs/b/architectures-and-processors-blog/posts/future-architecture-technologies-poe2-and-vmte)
is coming soon, which makes these permissions more complex. There's no
need to risk adding something too simple to handle those.
The ability to see the permissions the key refers to, and the final
permissions after the overlay, will be in a follow up PR.

-----------
[LangRef] Allow monotonic & seq_cst accesses to inter-operate with other accesses (#189014)
Currently, the LangRef says that atomic operations (which includes `unordered`
operations, which don't participate in the monotonic modification order) must
read a value from the modification order of monotonic operations.
In the following example, this means that the load does not have a store it
could read from, because all stores it may see do not participate in the
monotonic modification order:
```
; thread 0:
store atomic i32 1, ptr %p unordered, align 4
; thread 1:
store atomic i32 2, ptr %p unordered, align 4
load atomic i32, ptr %p unordered, align 4
```
The same applies if the load is monotonic instead of unordered (or if it is
replaced by a monotonic RMW operation). Either case seems wrong.
Similarly, the LangRef currently says "Each sequentially-consistent read sees
the last preceding write to the same address in this global order [of seq_cst
operations]." Strictly read, this means that the load in the following example
must read from the first store (or at least cannot read the second one),
because the second one is not sequentially consistent and therefore not in the
seq_cst order. That also seems wrong.
```
; thread 0
store atomic i32 1, ptr %p seq_cst, align 4
store atomic i32 2, ptr %p monotonic, align 4
load atomic i32, ptr %p seq_cst, align 4
```
This patch aims to resolve these inconsistencies.

Reland "[lldb][Linux] Read memory protection keys for memory regions (#193934)" (#193936)
This reverts commit 390a29ea833965f481a7011b07deed9612229d6e.
Two tests failed on the X86 buildbot but not in GitHub CI because the
buildbot has protection keys and the CI machines do not. I ran the tests
on an AArch64 host without protection keys, and only selected tests on a
simulated AArch64 machine with protection keys, so I did not find this
earlier.
The fix was to add "protection-key" to the list of possible
qMemoryRegionInfo response keys.

`FEAT_MPAMv2_VID` instructions and system registers, as introduced
in change d30f18d2c, are being removed at this time, as they've been
removed from the latest Arm ARM, which doesn't preclude them returning
in some form in future.
Other system registers introduced with `FEAT_MPAMv2` are unaffected,
and these continue to be ungated, but since `+mpamv2` gating is now
empty,
I'm removing this superfluous gating code.

[flang][OpenMP] Make OpenMPLoopConstruct inherit from OmpBlockConstruct (#193823)
Conceptually OpenMPLoopConstruct has the exact same structure as
OmpBlockConstruct: directive specification for the begin directive,
optional one for the end directive, and a block of code. The reason why
OpenMPLoopConstruct was not originally made to be a descendant of
OmpBlockConstruct was to preserve the behavior of AST visitors, where a
separate (type-based) visitor could be defined for the begin/end
directives of a block construct, and for a loop construct. The AST nodes
representing the begin/end directives in block and loop construct had
different types: Omp{Begin|End}Directive for block constructs, and
Omp{Begin|End}LoopDirective for loop constructs.
Today this distinction is not needed anywhere, and so the loop construct
will be represented in the same way as a block construct.

[lldb][Linux] Add overlay and effective permissions to "memory region" (#184115)
In this change I'm extending the "memory region" command to show users
the
overlay permissions that a protection key refers to, and the result of
applying that overlay to the page table permissions.
For example, protection key 0 refers to Perm0 in the por register.
```
(lldb) register read por
Perm0 = Read, Write, Execute
```
This is the default key, so many regions use it.
```
(lldb) memory region --all
<...>
[0x000ffffff7db0000-0x000ffffff7f40000) r-x /usr/lib/aarch64-linux-gnu/libc.so.6 PT_LOAD[0]
protection key: 0 (rwx, effective: r-x)
```
Protection keys can only change what was already enabled in the
page table. So we start with read and execute. Then a read/write/execute
overlay
is applied. We cannot add write, so the result is read and execute.
Here's an example of its use with a real crash (output edited):
```
(lldb) c
* thread #1, name = 'test.o', stop reason = signal SIGSEGV: failed protection key checks (fault address=0xffffff7d60000)
-> 106 read_only_page[0] = '?';
(lldb) memory region 0xffffff7d60000
[0x000ffffff7d60000-0x000ffffff7d70000) rw-
protection key: 6 (r--, effective: r--)
(lldb) register read por
Perm6 = Read
```
The calculation of permissions is implemented by a new ABI method.
It's in ABI for 2 reasons:
* These overlays are usually in a register (X86 and AArch64 are)
and that register name is architecture specific.
* The way the overlay values apply may differ between architecture.
AArch64 treats a set bit as adding a permission, but some may
treat it as removing.
Technically this is dependent on operating system and architecture.
However, so are the methods for removing non-address bits, and those
are in ABI too.
To test this I have changed the allocations in the test program
to use read+execute permissions by default. With read+write+execute
I could not observe that the overlay only changes enabled permissions.

[mlir][tosa] Fix integer bilinear (quantized) tosa.resize lowering to use floordivsi (#193821)
## Background
`tosa.resize` in bilinear integer (quantized) mode lowers to a
`linalg.generic`
body that, for each output pixel, computes a corresponding input
coordinate and
blends the four neighboring input pixels. The mapping is:
```
val = out_coord * scale_d + offset
index = val / scale_n // integer part — which input pixel to start from
delta = val - index * scale_n // fractional part, scaled to [0, scale_n)
```
`delta` is the interpolation weight toward the next pixel. The bilinear
formula
(integer path) is:
```
topAcc = pixel[y0,x0] * (scale_x - dx) + pixel[y0,x1] * dx
bottomAcc = pixel[y1,x0] * (scale_x - dx) + pixel[y1,x1] * dx
result = topAcc * (scale_y - dy) + bottomAcc * dy
```
For this to be a valid convex combination (interpolation, not
extrapolation),
`dx` and `dy` must be in `[0, scale_n]`.
The pixel indices `y0`, `y1`, `x0`, `x1` are computed by
`getClampedIdxs`:
```cpp
y0 = clamp(iy, 0, H-1)
y1 = clamp(iy+1, 0, H-1)
```
---
## The Bug
The integer path uses `DivSIOp` (truncation toward zero):
```cpp
// getIndexAndDeltaInt — mlir/lib/Conversion/TosaToLinalg/TosaToLinalg.cpp
index = arith::DivSIOp::create(b, val, scaleN); // truncates toward zero
delta = arith::MulIOp::create(b, index, scaleN);
delta = arith::SubIOp::create(b, val, delta); // = val - (val/scaleN)*scaleN
```
When `val < 0` (which happens at boundary output pixels when `offset` is
negative), `DivSIOp` truncates toward zero instead of toward -∞. This
produces
a negative remainder, i.e. a negative `delta`, which causes
extrapolation.
Note: the code comment on line 2058 already says `// ix = floor(x /
scale_n)`,
but the code uses truncation — this mismatch is the root cause of the
bug.
The float path (`getIndexAndDeltaFp`) uses `FloorDivSIOp` and is
unaffected:
with floor division, `r = val - floor(val/scaleN)*scaleN` is always in
`[0, scaleN-1]`.
---
## Concrete Example
**Setup:** 2×2 input upsampled to 4×4, `scale=[4,2,4,2]`,
`offset=[-1,-1]`
- `scale_y_n=4`, `scale_y_d=2`, `scale_x_n=4`, `scale_x_d=2`
- `offset_y=-1`, `offset_x=-1`
- Input: `tensor<1x2x2x1xi8>` with `input[0,0,0,0]=100`, all others `0`
**At output pixel (0,0):**
```
val = 0 * 2 + (-1) = -1
```
### Without any fix (DivSIOp, buggy)
```
iy = DivSIOp(-1, 4) = 0 // truncates -0.25 toward zero
dy = -1 - 0*4 = -1 // OUT OF RANGE: should be in [0, 4]
y0 = clamp(0, 0, 1) = 0
y1 = clamp(0+1, 0, 1) = 1 // different rows
ix = DivSIOp(-1, 4) = 0
dx = -1 // same issue
x0 = clamp(0, 0, 1) = 0
x1 = clamp(0+1, 0, 1) = 1
// pixels:
y0x0 = input[0,0,0,0] = 100
y0x1 = input[0,0,1,0] = 0
y1x0 = input[0,1,0,0] = 0
y1x1 = input[0,1,1,0] = 0
topAcc = 100*(4-(-1)) + 0*(-1) = 500 // EXTRAPOLATION
bottomAcc = 0*(4-(-1)) + 0*(-1) = 0
result = 500*(4-(-1)) + 0*(-1) = 2500 // WRONG
```
### Fix w/ FloorDivSIOp
```
iy = FloorDivSIOp(-1, 4) = -1 // floors -0.25 toward -∞
dy = -1 - (-1)*4 = 3 // naturally in [0, scale_n-1]
y0 = clamp(-1, 0, 1) = 0
y1 = clamp(-1+1, 0, 1) = 0 // SAME row — both snap to boundary
dx = 3 (same by symmetry)
// all four neighbors collapse to the same boundary pixel:
y0x0 = y0x1 = y1x0 = y1x1 = input[0,0,0,0] = 100
topAcc = 100*(4-3) + 100*3 = 400
bottomAcc = 100*(4-3) + 100*3 = 400
result = 400*(4-3) + 400*3 = 1600 // correct
```
`y0=y1=0` means boundary replication is enforced by `getClampedIdxs`,
making
`dy` irrelevant.
## Semantic Analysis of the fix
- `iy=-1` correctly signals "this position is before the first input
pixel."
- `getClampedIdxs` does its intended job: both `y0` and `y1` snap to the
boundary pixel, enforcing replication explicitly.
- `dy=3` **appears** valid (it's in `[0, scale_n-1]`) but is
semantically
meaningless: the true position is `-0.25`, which is outside the image —
there
is no "3/4 toward the next pixel" to interpolate toward. It is harmless
only
because `y0=y1`.
- Same analysis for dx=3 by symmetry.
- Fixes the root cause (wrong division op, matching the existing code
comment
and mirroring the float path), but `delta` still carries a misleading
value
at out-of-bounds positions.

[CIR] Introduce LocalInitOp, & lower static locals (#193576)
During an investigation of something else, I discovered that our
handling of static-local as a ctor/dtor on a GlobalOp meant that it
couldn't actually be initialized with reference to any local, parameter,
or member declarations. This is obviously problematic.
This patch instead introduces a `LocalInitOp`, which is an operation
that represents the location of initialization for the static local.
This is lowered during lowering-prepare, same as we did previously (in
fact, it uses basically the exact same lowering code, with some slight
modifications).
Lowering from AST itself splits slightly from global declarations, but
the two share implementation as closely as possible.
At the moment, this operation only works for static-locals, and has a
handful of asserts to do the same. It is intended that the
thread-local-storage use the exact same mechanism, with some slight
modifications to the lowering-prepare pass to introduce the different
init behavior.

# Contents
* Adds a new warning emitted for use-after-free.
* Renames `reportUseAfterFree` to `reportUseAfterScope`, since the old
name was misleading (the warnings are still called `use_after_scope`).
* Adds a new `AccessPath::Kind` value, `NewAllocation`, which is used
for loans issued from `new` allocations.
* Adds `VisitCXXNewExpr` and `VisitCXXDeleteExpr`, which handle loan
issuance and origin propagation for `new` and `delete`.
* Comes with extensive test coverage for the new features, including new
use-after-free tests and use-after-scope coverage for `new`.
Remerges #192504
# Changes over original PR
* Fixed a crash when allocating `void*`, and added a regression test for
it
* The `AccessPath` root implementation was changed in #193520, so this

This patch introduces simple GC for clangd built module files to avoid
the clangd built module cache to increase infinitely.
The strategy is, in a clangd built module file cache, if the clangd
built module (we think all PCM files in clangd cache are built by
clangd) was not accessed in a time (by default 3 day, controlled by
--modules-builder-versioned-gc-threshold-seconds)，clangd will remove it.
The strategy is not perfect. e.g., I heard in some systems, the atime
was forbid or not update. But given a trade off between usability and
maintainability. I feel the current stategy is fine.

[lldb][AArch64][Linux] Rename "por" register to "por_el0" (#193983)
As agreed with my Arm colleagues working on GDB.
The suffix means we are matching the architectural name exactly, and
reducing confusion if you're
debuging multiple exception levels where there could be por_el<N> as
well.
In the process of updating the tests I found some
"register read" output has changed alignment so I
have fixed that too.

This enables the instruction to be disassembled regardless of what bits
are in those fields, which helps diagnose broken code. Previously, the

of app address space; addresses differing only in bits 28-31 alias in
the shadow. kAppAddr is set to 0xC0000000 to size the mmap to exactly
the 1GB shadow region.

This reverts commit a1d11348aba4b70295ef9ada4a13a722455165d3.
Two problems have been identified:
- The expansion for powi was functionally wrong - the second argument
stales scalar even when the first is a vector.
- AArch64 uses the Expand option on libcalls to select vector libcalls
in some cases. The test coverage for this uses -start-after which
happens to miss this pass.

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

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

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

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

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

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

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

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

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

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

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

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

IR verification failures (invalid intermediate IR after pattern
application):
- Expand nested op checks in Switch, Loop, CleanupScope, and TryOp
flattening to include all structured CIR ops (ScopeOp, IfOp, TernaryOp,
etc.), not just CleanupScopeOp. Break/continue/return inside nested
structured ops creates invalid cross-region branches when the enclosing
op hasn't been flattened yet (tests: switch.cir, loop.cpp,
cleanup-scope-return-in-loop.cpp, partial-array-cleanup.cpp, switch.cpp,
typeid.cpp, flatten-cleanup-scope-simple.cir,
flatten-cleanup-scope-multi-exit.cir)
- Relax CIR_ResumeOp ParentOneOf to include all structured ops, since
cir.resume can temporarily appear inside them during flattening (test:
new-delete-deactivation.cpp). Feels weird to do that, but extended
documentation to account for.
- Change loop region constraints from SizedRegion<1> to
MinSizedRegion<1> for cond/step regions, since cleanup scope flattening
inside these regions may create multiple blocks (test:
loop-cond-cleanup.cpp)

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

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

unrolling and we aren't able to honor their request.
- Only emit passing or missed optimization remarks when we're certain
that unrolling will succeed or fail.
- In lieu of emitting more informative passing/failing optimization
remarks when unrolling may still fail/pass, emit analysis optimization
remarks so users can understand the reason as to why unrolling may have
failed on that loop.

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

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

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

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

- A new pass manager wrapper (AArch64StackTaggingPreRAPass) has been
created.
- The legacy pass manager wrapper has been renamed to
AArch64StackTaggingPreRALegacy and updated to call the shared
implementation.
- The pass is registered in AArch64PassRegistry.def to make it available
to the New PM.

`x30` afterwards, to uphold the invariant that `x30` always holds a

without any additional rewrites.

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

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

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

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

Add checks to ensure that an alias and its target have compatible types:
- Generate an error if a function alias points to a variable or vice
versa.
- Issue a warning for mismatches in function types.
- Ignore type discrepancies for variables.
This behavior aligns with similar diagnostics in GCC.

[compiler-rt][sanitizer] Remove linux/scc.h (#194116)

Linux Kernel has removed scc.h header completely from the source code
Therefore, we need to remove the usage in compiler-rt/sanitizer too.
https://github.com/torvalds/linux/commit/64edfa65062dc4509ba75978116b2f6d392346f5#diff-1ca78e598a5041ee51ae795d168435afad598b82a7a0ce80f215993589b96c7c
Without removing it, not only it breaks compiler-rt but also GCC build
since GCC always builds libsanitizer for linux targets.
After merging this we will need to cherry pick to GCC.

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

specifier (`auto`) cannot be used to declare conversion function or

not non-template case.

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

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

This helps by avoiding the difficult predicate generation in scalar, using
natural extends to all-zero or all-ones in scalar as opposed to re-extending
them in vector registers.

now as other places can generate those nodes. performVP_TRUNCATECombine
needs to be updated to match the plain non-VP node when forming vaaddu.

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

- **Note**: Moved theI nstruction Replacement Table and cross-function
cached maps as members of the Impl class.
- **Note**: Updated `InstReplInfo::RC` to be a pointer rather than a
stack object, because we're putting it into MRI
[here](https://github.com/llvm/llvm-project/blob/704c60fe9110256d2698d8e56b8c44ec5d1e733f/llvm/lib/Target/AArch64/AArch64SIMDInstrOpt.cpp#L532).
- Renamed existing pass with "Legacy" suffix and updated references
- Added NewPM pass AArch64SIMDInstrOptPass
- Updated pass type to `aarch64-simd-instr-opt` (prev:
`aarch64-simdinstr-opt`)
No existing `.mir` tests to update.

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

The compiler version was bumped in

include this. We should probably just hash pin the version in future

what it should really be checking that the iterator is not the end
iterator. Fix this assert by introducing and using a variant of
vputils::findUserOf.

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

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

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

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

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

[libclc] Only check the triple architecture for libclc (#194149)
Summary:
Previously, `nvptx64--` would reject `nvptx64-unknown-unknown`. Two
options, either normalize all the triples in CMake, or just check the
architecture. I went with the former because it makes it easier for
people to pass different values.

consuming load, store, and prefetch ops. It also deprecates the
update_nd_offset op.

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

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

Move the logic to validate FOR users and introduce the split directly to

It also means sinking only needs to be done once, instead for each
VPlan.

[InstCombine] Div ceil optimizations (#190175)
Relates: https://github.com/llvm/llvm-project/issues/187838
This PR improves handling of `div_ceil` from rust (which emits a div +
rem).
Currently, these three rust functions:
```rust
use std::hint::assert_unchecked;
#[unsafe(no_mangle)]
pub fn div_ceil_without_assume(x: u32) -> u32 {
x.div_ceil(7)
}
#[unsafe(no_mangle)]
pub fn div_ceil_with_assume(x: u32) -> u32 {
unsafe {
assert_unchecked(x <= u32::MAX - 7);
}
x.div_ceil(7)
}
#[unsafe(no_mangle)]
pub fn div_ceil_with_range(x: u32) -> u32 {
x.count_zeros().div_ceil(7)
}
```
Will emit this IR (cleaned up): The IR looks pretty good to me as both
the assert_unchecked and the popcount are providing range information.
```llvm
define noundef range(i32 0, 613566758) i32 @div_ceil_without_assume(i32 noundef %x) unnamed_addr {
start:
%d = udiv i32 %x, 7
%r = urem i32 %x, 7

}

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

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

Anyway the llvm IR when run through opt at -O2:
On main:
The only changes I see are the urem being rewritten to a mul + sub for
all the instructions, and the range information is persisted but not
used.
```llvm
define noundef range(i32 0, 613566758) i32 @div_ceil_without_assume(i32 noundef %x) unnamed_addr {
start:
%d = udiv i32 %x, 7

%r.decomposed = sub i32 %x, %0
%_4.not = icmp ne i32 %r.decomposed, 0
%1 = zext i1 %_4.not to i32
%_0.sroa.0.0 = add nuw nsw i32 %d, %1
ret i32 %_0.sroa.0.0
}
define noundef range(i32 0, 613566757) i32 @div_ceil_with_assume(i32 noundef %x) unnamed_addr {
start:

tail call void @llvm.assume(i1 %cond)

%_5.not = icmp ne i32 %r.decomposed, 0
%1 = zext i1 %_5.not to i32
%_0.sroa.0.0 = add nuw nsw i32 %d, %1
ret i32 %_0.sroa.0.0
}
define noundef range(i32 0, 6) i32 @div_ceil_with_range(i32 noundef %x) unnamed_addr {
start:
%self = xor i32 %x, -1
%0 = tail call range(i32 0, 33) i32 @llvm.ctpop.i32(i32 %self)
%d.lhs.trunc = trunc nuw nsw i32 %0 to i8
%d3 = udiv i8 %d.lhs.trunc, 7
%d.zext = zext nneg i8 %d3 to i32
%1 = mul i8 %d3, 7
%r4.decomposed = sub i8 %d.lhs.trunc, %1
%_6.not = icmp ne i8 %r4.decomposed, 0
%2 = zext i1 %_6.not to i32
%_0.sroa.0.0 = add nuw nsw i32 %2, %d.zext
ret i32 %_0.sroa.0.0
}
declare void @llvm.assume(i1 noundef)
declare i32 @llvm.ctpop.i32(i32)
```
However, both the assume and the popcount provide range information so
we can do an optimization. Div_ceil is emitted as a udiv and urem. We
can combine them given the following rules:
Assuming you have floor division of X / Y, we can add Y - 1 to X and
floor division will always give us (floor_divide(X / Y) + 1) which gives
us the same result.
So the formula in general is:
```
div_ceil(X, Y) = X / Y + (1 if X % Y > 0 else 0) -> X + Y - 1 / Y
```
But this fails since I forgot about wrapping. So we need a condition
that X + Y - 1 does not wrap, and of course Y cannot be 0. Technically
we should ignore Y / 1 since that's a trivial identity.
That gets us:
```
add(udiv(X, Y), zext(icmp ne(urem(X, Y), 0))) -> udiv(add nuw(X, Y - 1), Y)
```
[Alive proof here](https://alive2.llvm.org/ce/z/nBvyv4)
This is where I thought I was done, because this should handle the range
and assume case (the assume case provides less information than the
popcount because popcount's range is narrower for X). So I thought I was
done.
Unfortunately this only optimizes one case (the assume case with the
wide code). The culprit here is in the popcount case, there's a trunc
for the popcount to bound it to an i8 since narrower arithmetic allows
for better optimizations before zero extending.
```llvm
%d.lhs.trunc = trunc nuw nsw i32 %0 to i8
%d3 = udiv i8 %d.lhs.trunc, 7
%d.zext = zext nneg i8 %d3 to i32
%r4 = urem i8 %d.lhs.trunc, 7
%_6.not = icmp ne i8 %r4, 0
%1 = zext i1 %_6.not to i32
```
So we need to handle another form, when the udiv needs to be zexted to
the return type (because it was previously trunced, due to the
popcount).
```
add(zext(udiv(X, Y)), zext(icmp ne(urem(X, Y), 0))) -> zext(udiv(add nuw(X, Y - 1), Y))
```
[Alive2 Proof](https://alive2.llvm.org/ce/z/w7bRZW)
There was another oddity I found that trunced information wasn't passing
constant ranges, so I added that to ValueTracking.cpp to fix this fold
too.
On this branch the IR now transforms:
```llvm
define noundef range(i32 0, 613566758) i32 @div_ceil_without_assume(i32 noundef %x) unnamed_addr {
start:
%d = udiv i32 %x, 7
%0 = mul i32 %d, 7
%r.decomposed = sub i32 %x, %0
%_4.not = icmp ne i32 %r.decomposed, 0
%1 = zext i1 %_4.not to i32
%_0.sroa.0.0 = add nuw nsw i32 %d, %1
ret i32 %_0.sroa.0.0
}
define noundef range(i32 0, 613566757) i32 @div_ceil_with_assume(i32 noundef %x) unnamed_addr {
start:
%cond = icmp ult i32 %x, -7
tail call void @llvm.assume(i1 %cond)
%0 = add nuw i32 %x, 6
%_0.sroa.0.0 = udiv i32 %0, 7
ret i32 %_0.sroa.0.0
}
define noundef range(i32 0, 6) i32 @div_ceil_with_range(i32 noundef %x) unnamed_addr {
start:
%self = xor i32 %x, -1
%0 = tail call range(i32 0, 33) i32 @llvm.ctpop.i32(i32 %self)
%d.lhs.trunc = trunc nuw nsw i32 %0 to i8
%1 = add nuw nsw i8 %d.lhs.trunc, 6
%2 = udiv i8 %1, 7
%_0.sroa.0.0 = zext nneg i8 %2 to i32
ret i32 %_0.sroa.0.0
}
declare void @llvm.assume(i1 noundef)
declare i32 @llvm.ctpop.i32(i32)
```
And we get this asm emitted:
```asm

When a vector integer-to-float conversion is followed by a multiply with a
reciprocal power-of-two constant, we can fold both operations into a single
SCVTF or UCVTF instruction with a fixed-point shift operand.
For example, `fmul(sitofp(v2i32 x), <0.5, 0.5>)` becomes `scvtf.2s v0, v0, #1`.
This is a reworked version with several improvements over the original
submission:
- Rewrite the C++ operand matcher to share implementation with the existing
`SelectCVTFixedPointVec` (MOVIshift, FMOV, and DUP handling with correct
truncation for f16)
- Add `uitofp`/`ucvtf` patterns via a `CVTFRecipPat` multiclass
- Add full GlobalISel support (`GIComplexOperandMatcher` + renderer)
Supported vector types: `v2f32`, `v4f32`, `v2f64`, `v4f16`, `v8f16`.
Fixes #94909

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

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

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

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

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

[NVPTX] Improve error diagnostic when handling unknown intrinsics (#191194)
Following up on #146726, it may be desirable to gracefully fail the
compilation in the presence of unknown NVVM intrinsics, which
cannot be lowered by the NVPTX backend, rather than silently
emitting invalid PTX.

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

Both MCContext::MCContext and TargetMachine::getMCAsmInfo treat
MCAsmInfo as a pointer that must be non-null. Make the contract
explicit:
* MCContext's constructor takes `const MCAsmInfo &MAI`.
* TargetMachine::getMCAsmInfo returns `const MCAsmInfo &`.
Make this change now since the MCContext ctor has recently been updated.

[AArch64] Sanitise pow inputs using a target DAG combine (#192958)
Sometimes we see LLVM IR like this:
%pow = call fast <4 x float> @llvm.pow.v4f32(...)
%fcmp = fcmp fast ...
%res = select <4 x i1> %fcmp, <4 x float> %val, <4 x float> %pow
where the pow intrinsic is called unconditionally, but only certain
lanes of the result are used. In fact, LLVM actively encourages code
like this due to the intrinsic being marked as safe to speculatively
execute. However, we know when using certain vector libraries like
ArmPL that this can be very costly if the unused lanes would take
the pow call down an expensive path. For example, if an input to
pow is a special value (inf, NaN, -0) then it triggers slow special
case handling, and ultimately the result is going to be ignored
anyway. For this reason we prefer to sanitise the pow input to
use 'safe' values when we know the result is going to be discarded.
The above example LLVM IR would then look like
%fcmp = fcmp fast ...
%sel = select <4 x i1>, <4 x float> splat(float 1.0), ...
%pow = call fast <4 x float> @llvm.pow.v4f32(<4 x float> %sel, ...)
%res = select <4 x i1> %fcmp, <4 x float> %val, <4 x float> %pow
where the value 1.0 is chosen due to the fact pow is known to always
return 1.0 for all powers.

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

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

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

[Clang] No longer advertise support for coroutines on x86 windows. (#193456)
There are a large number of long standing issues with coroutines on
x86_32 windows as discussed here

- #59382
- #58556
- #58543
- #56989
- #193161
- #136481
As such this patches
- No longer defines `__cpp_impl_coroutine` on that platform
- Warn when using coroutines on that platform
The reason to not plainly error is that it would break too much valid
valid code, ie there are people who probably use coroutines sucessfully.
And we also want to keep testing on that platform, up until the point we
were to pull support completely.
Hopefully this is all temporary and someone will feel compelled to
improve the situation enough that we can unceremoniously revert this
patch.

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

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

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

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

[OpenMP][OMPIRBuilder] Use device shared memory for arg structures (#150925)
Argument structures are created when sections of the LLVM IR
corresponding to an OpenMP construct are outlined into their own
function. For this, stack allocations are used.
This patch modifies this behavior when compiling for a target device and
outlining `parallel`-related IR, so that it uses device shared memory
instead of private stack space. This is needed in order for threads to
have access to these arguments.

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

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

This patch moves tablegen definitions that could be used for all kinds

`OpenMP_HeapAllocClause` that can be reused.
Descriptions are updated to follow the format of most other operations
and the custom verifier for `omp.target_allocmem` is removed as it only
made a redundant check on its result type.

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

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

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

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

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

[Clang] prevent crash in delayed default-argument lambda captures (#176749)
Fixes #176534
---
This patch resolves a crash when parsing delayed default arguments that
contain lambda expressions.
```cpp
struct S {
void f(int x, int = sizeof([x] { return x; }()));
};
```
When late-parsing default arguments that contain lambdas, `Sema` builds
a `FunctionScopes` stack containing only the lambda scope
(`FunctionScopes.size()` equals 1), however, `tryCaptureVariable`
expects an enclosing function scope outside the lambda scope
https://github.com/llvm/llvm-project/blob/41e231cae38028473dd327e8de5f65792b521ffe/clang/lib/Sema/SemaExpr.cpp#L19473-L19474
https://github.com/llvm/llvm-project/blob/41e231cae38028473dd327e8de5f65792b521ffe/clang/lib/Sema/SemaExpr.cpp#L19518
Scope capture handling logic decrements `FunctionScopesIndex` to align
declaration contexts
https://github.com/llvm/llvm-project/blob/41e231cae38028473dd327e8de5f65792b521ffe/clang/lib/Sema/SemaExpr.cpp#L19696
and later relies on it when traversing and accessing outer scopes
https://github.com/llvm/llvm-project/blob/41e231cae38028473dd327e8de5f65792b521ffe/clang/lib/Sema/SemaExpr.cpp#L19522-L19524
preserving the function scope in the late-parsing path prevents invalid
traversal during lambda capture handling

Use ? instead of 0 in the tablegen definitions for VOPD containing
v_mov. This enables the instruction to be disassembled regardless of
what bits are in those fields, which helps diagnose broken code.
Previously, the disassembler would reject these.

[offload] Fix use of AsyncInfoWrapper's finalize function (#194098)
The expected use is to forward the error from the asynchronous
operation's issuing (e.g., launchImpl) directly into the
AsyncInfoWrapper::finalize(). The check of the error is already
performed inside that function. No need to forward a dummy success error
code.

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

[Attributor] Support SPIR-V address spaces (#192725)
Right now Attributor assumes that if the the target is a GPU is can use

address space, but that's not true in general, so add SPIR-V support,
which uses different values.
This fixes an instruction incorrectly being marked as dead and optimized
out for an OpenMP SPIR-V offloading example.

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

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

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

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

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

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

The HwMode is already used for operands representing an effective

not clear from the naming. This change
- introduces the hw-mode dependent register class `GxRC`, and the
associated register operands
- removes register class `ptr_rc_idx_by_hwmode`, and replaces the only
use with `gxrc`
- uses the `EQV` instruction as an example how to use the new class

[PowerPC] Simplify implementation of atomis loads (#191044)
The code for atomic loads is verbose. There are 10 different operations
and 4 memory sizes to support, which means 40 pseudo instructions are
used, with all the details repeated. This PR changes the following:
- Use a loop over the operations and the sizes to create the pseudo
instruction
- Adds the memory size as last operand to the pseudo instruction
- Updates the C++ code to take advantage of the memory size in the
pseudo instruction

[WebAssembly] Support f16x8.demote_f32x4_zero (#193564)
Add support for the f16x8.demote_f32x4_zero instruction. This
instruction converts a v4f32 vector to a v4f16 and pads the result with
zeros to fill the 128-bit register.
This enables efficient lowering of fptrunc operations from v4f32 to
v4f16 when the result is zero-extended or when only the low lanes are
needed. A DAG combine is included to recognize these patterns and fold
them into the new instruction.

[CIR] Emit frexp, modf, and powi builtins as library calls (#193795)
`__builtin_frexpf`, `__builtin_modf`, `__builtin_powi`, and related

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

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

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

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

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

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

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

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

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

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

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

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

[CIR] Remove overly strict end_catch assertion in catch handler flattening (#193796)
The assertion in `flattenCatchHandler` required `end_catch` to be the
last operation before `yield` in catch handlers, with only branches in
between. Complex catch handlers with cleanup code or nested control flow
can have additional operations between `end_catch` and `yield`. The
yield-to-branch replacement does not depend on `end_catch` position.

HLSL allows per-declaration matrix layout overrides via the row_major
and column_major keywords. Prior to this commit, matrix layout was only
controlled globally via the -fmatrix-memory-layout command-line flag
(LangOptions::DefaultMatrixMemoryLayout). This commit adds the parsing
and semantic analysis infrastructure needed to support per-declaration
layout, matching DXC behavior.

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

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

lowered into the omp.scope MLIR op, but MLIR-to-LLVM IR translation is
not yet implemented.
When nowait is combined with reduction, the reduce function argument to
__kmpc_reduce_nowait is passed as null to prevent the runtime from
selecting the tree reduction method for host, which carries a barrier.

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