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

[lldb] Use GetOutputStream instead of repeated AppendMessageWithFormat (#189674)
AppendMessageWithFormat is odd because it's the only AppendMessage...
method that does not add a newline for you.
This PR changes places that use it to output raw text, or build
up a large message. They now use GetOutputStream() instead,
which makes it a bit clearer that we're building one big message,
and where newlines end up.
This removes the last callers of AppendMessageWithFormat, so I am
removing it too.

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

[lldb][test] Remove libc++ dependency in common libcxx-simulators header (#190922)
After we made the test-suite mostly compile against system libc++ (in
https://github.com/llvm/llvm-project/pull/190034), the `invalid-vector`
test started failing on the macOS bots with:
```

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

[lldb] Remove "AppendNoteWithFormat(" (#190941)
This method is surprising because it does not automatically add a
newline like AppendNoteWithFormatv and other AppendNote... functions.
If you need to manage the newlines yourself, you should add an
equivalent of GetOutputStream for notes. See
efc0bcdf542475301805ed8478a5d5845f44dc53 for examples of that done for
messages.
AppendNoteWithFormat( is not used at all either (there are a few callers
of `AppendNoteWithFormatv(`).

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

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

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

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

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

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

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

This allows upstream zero/sign extensions to be eliminated when only a
subset of bits is used after intrinsics.

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

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

[CIR][ABI] Add _BitInt flag to IntType (#188113)
Add an optional `bitint` parameter to `cir::IntType` so CIR can

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

[libc++] Implement LWG4477: placement operator delete should be constexpr (#189915)
Implement the proposed resolution of
[LWG4477](https://cplusplus.github.io/LWG/issue4477).
P2747R2 made placement `operator new` constexpr since C++26, but the
corresponding placement `operator delete` was not. When a constructor
throws during placement new in a constant expression, the placement
delete is invoked and fails because it's not constexpr.
Add `_LIBCPP_CONSTEXPR_SINCE_CXX26` to placement `operator delete(void*,
void*)` and `operator delete[](void*, void*)`.
Closes #189843

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

And remove the function entirely as there are now no

This last use of AppendWarningWithFormat does not

that it should have done, so I am ok to convert it.
It was added by 56535a090d91ff10a60c884bacbd314dcf9659db,
and the other branches of the if/else will add newlines.
Also it seems like an important message that would benefit
from being on its own line.
There are no tests that expect this specific message,
which makes some sense as it seems to have been added
to cover a race condition that only sometimes happens.

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

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

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

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

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

[VPlan] Lower CanIVIncrementForPart in convertToConcreteRecipes. (#190844)
Move the lowering of CanonicalIVIncrementForPart from generate() to
convertToConcreteRecipes, converting it to an Add VPInstruction at the
VPlan level. This enables VPlan-level simplifications (e.g., folding add
0, x) and prepares for adding a 3-operand form.

[SelectionDAG] Recurse through mask expression trees in WidenVSELECTMask (#188085)
WidenVSELECTMask currently handles only two mask shapes: a bare SETCC
or a single AND/OR/XOR of exactly two SETCCs. Anything deeper bails out
to the generic condition widening path, which often introduces
unnecessary narrow/widen roundtrips (xtn+sshll on AArch64,
packssdw+vpmovsxwd on X86).
Replace the hand-coded cases with a recursive widenMaskTree that walks
through SETCC, AND/OR/XOR, FREEZE, VECTOR_SHUFFLE, SELECT/VSELECT, and
all-ones/all-zeros BUILD_VECTORs.

Fix assertion in `loop-vectorize` on loops that contains

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

The motivating problem is, when we pass -target-features +tagged-globals
as well as -fsanitize=hwaddress, which adds a second copy, the module
is incompatible with one built with only one `-target-features
+tagged-globals`.

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

When the name is too long to fit in sockaddr_un::sun_path's 104
character buffer, we now surface the error condition, rather than
silently truncating and failing the test with an "address in use Bind
error". We also shorten the name a bit to give more headroom on CI
systems that define an explicit TMP_DIR that acts as a prefix to the
path created by these tests.

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

`lowerConstantPtrAuth` silently miscompiled `ConstantPtrAuth` constants

of erroring.
Changes:
- Handle `ConstantPointerNull` bases explicitly
- Error via `reportFatalUsageError` on any remaining unresolved base
(e.g. nested ptrauth) instead of silently miscompiling

There is a case when building standalone offload via runtimes where
LLVM_BINARY_DIR is set to the installed llvm location. Currently, this
header is not being installed and results in a build failure.
Fixes issue introduced with #190423.

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

[CIR][ABI][NFC] Update ABI lowering design doc with implementation experience (#188617)
Three documentation improvements based on implementation experience:
- Improve Section 4.4 flow diagram: replace flat step-by-step diagram
with
layered version showing which architectural layer (MLIR adapter, LLVM
ABI
library, dialect-specific) owns each step.
- Note dialect-aware type mapping: dialects with custom types (e.g.
cir::IntType is not mlir::IntegerType) may need dialect-aware mapping
alongside the generic mapper to preserve signedness, pointer identity,
and
record field structure.
- Update ABIRewriteContext interface: describe the actual two-method
interface
(rewriteFunctionDefinition, rewriteCallSite) instead of the 15-20
fine-grained methods originally proposed.

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

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

single monotonically increasing counter in Target.
Provider IDs are now assigned by
Target::AddScriptedFrameProviderDescriptor
and used directly as the chain ID in Thread, so
RegisterScriptedFrameProvider
returns the same ID used by 'bt --provider'. Also add duplicate
detection to
emit a warning when registering a provider with the same class name and
arguments twice.

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

to YAML instead - add entries to the `macros` list that point to the
correct `macro_header` to ensure it would be included.

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

named barrier signaling with the m0-less form. Enable this behavior.

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

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

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

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

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

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

- _fetchInitializingClassList for startup code in dyld.
- dyld4::RuntimeState::_instantiateTLVs for thread locals.
Fixes https://github.com/llvm/llvm-project/issues/115992, now it shows
the following instead (in a project using thread locals):

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

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

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

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

We need this for architectures like x86 where division by zero (or
overflow for sdiv/srem) can trap. But on AArch64 and RISC-V division
doesn't trap so we don't actually need to mask off any divisors. Not
only that, but there are also dedicated vector division instructions
that can be predicated.
Originally we tried to optimize this on RISC-V by transforming `udiv x,
(select mask, y, 1) -> vp.udiv x, y, mask`. However this isn't actually
a correct transform because the masked off lanes aren't poison, but x.
So with the safe-divisor pattern we end up losing the information that
the masked off lanes aren't actually used and can be poison.
This patch adds masked intrinsics for udiv and friends to
represent the semantics where the masked off lanes don't trap and
produce poison. This will allow AArch64 and RISC-V to emit their native
predicated division instructions and avoid the redundant select
instruction.

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

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

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

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

[clang][CIR] Add lowering for vcvt_n_ and vcvtq_n_ conversion intrinsics (#190961)
This PR adds lowering for the conversion intrinsics with an immediate
argument (identified by `_n_` in the intrinsic name), excluding FP16
variants.
It also moves the corresponding tests from:
* clang/test/CodeGen/AArch64/neon_intrinsics.c
to:
* clang/test/CodeGen/AArch64/neon/intrinsics.c
The lowering follows the existing implementation in
CodeGen/TargetBuiltins/ARM.cpp and adds the `getFloatNeonType` helper
to support it. The remaining changes are code motion and refactoring.

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

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

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

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

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

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

[AArch64] Fix broken SME code with GlobalISel (#191140)
The checks introduced in #190135 are too restrictive because no SVE or

functions. Now it generates incorrect code for
streaming-compatible/agnostic-ZA functions when the function has no
`+sve` or `+sme`.

[Clang] Do not try to create invalid variable specializations. (#190960)
When a variable specialization is ambiguous,
we would still create a node for it.
If the first such specialization takes places in a sfinae context, ie
when appearing in a concept, the initial diagnostic was silence, but no
further errors were emitted on that specialization as the variable was
created anyway.
Instead we do not create a specialization in this case.
Fixes #132592

[libc] Add cpio.h to Linux target public headers (#191177)
Added libc.include.cpio to TARGET_PUBLIC_HEADERS for all Linux
architectures: aarch64, arm, i386, riscv, and x86_64.
This enables generation of cpio.h when building with
LLVM_LIBC_FULL_BUILD.

stderr_lines_to_read argument but didn't adjust the call site in
TestAppleSimulatorOSType. This patch just removes the extra arg here
too.

[Clang] prevent constexpr crash on invalid overrides (#184048)
Fixes #183290
---
This PR fixes a crash during `constexpr` evaluation that occurred after
detecting an invalid override. It now marks the overriding method as
invalid when override checks fail.

Since 99aa33d ([VPlan] Explicitly unroll replicate-regions without

handled. The change is non-functional because simplifyRecipes is run
after unrollByUF, which dissolves replicate regions.

[flang][NFC] remove ambiguous fir::unwrapInnerType helper (#191189)
`fir::unwrapInnerType` has the odd behavior of returning an empty type
for things like i32, causing BaseBoxType::unwrapInnerType to return a
null type for fir.box<i32> which was not intended.
Remove the helper, no user really needed the null type behavior, replace
its few usage by fir::getFortranElementType and update
BaseBoxType::unwrapInnerType to do the intended behavior.

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

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

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

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

[compiler-rt] [Darwin] Move macOS ASAN reservation above 512G (#191039)
On macOS, the first 512G may contain platform-specific reservations. To
ensure compatibility with these reservations, this changes ASAN to
always map shadow memory above 512G on macOS.

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

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

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

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

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

This is aimed at addressing questions recently raised in

I guess this is technically a policy change, but does not change

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

[CIR] Add canonicalizer for CleanupScopeOp (#191084)
This change adds a canonicalizer for CleanupScopeOp that erases any
cleanup scope with a trivial cleanup region, inlining the contents of
the body region into the block in place of the cleanup scope op. It also
erases any EH-only cleanup scope whose body region contains only a yield
operation, dropping the cleanup region contents even if they were not
trivial because the EH cleanup is not reachable in this case.

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

[ADT] Fix SmallVector append with input iterators (#191030)
append()/assign()/insert() iterate over the iterator twice -- once to

permitted with forward iterators, not input iterators.
For append()/assign(), implement a version that uses emplace_back() in
a loop. insert() at the end is append(); for insert() in the middle,
append() elements first and then rotate them into their correct
position.

It also cause non-determinism, where the inliner adds !inline_history

[clang][ssaf] Refactor path validation into shared `FormatFile` utilities (#188847)
This patch introduces the following changes:
- Renames `SummaryFile` to `FormatFile` to better reflect that the
struct pairs a file path with its resolved `SerializationFormat`.
- Consolidates duplicated input/output path validation logic from
`SSAFLinker.cpp` and `SSAFFormat.cpp` into shared
`FormatFile::fromInputPath()` and `FormatFile::fromOutputPath()` methods
in `Tool/Utils.{h,cpp}`
- Moves error message constants from the public header into the `.cpp`
file and rewords them.
- Removes per-tool local error messages and filesystem logic that are
now handled centrally.
- Updates all affected lit tests to match the new error message wording
and adds a test for directory-as-input.

[NVPTX] Merge consecutive elements while buffering constant vectors with sub-byte datatype. (#183628)
NVPTXAsmPrinter currently buffers one element at a time while generating
PTX for constant global vectors. This causes an assertion when dealing
with sub-byte datatype (like i4) since we allocate lesser buffer size.
This PR fixes the printer to merge consecutive elements to form a full
byte before buffering.

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

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

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

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

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

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

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

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

[SelectionDAG] Salvage debuginfo when combining load and z|s ext instrs. (#188544)
Reland 2b958b9ee24b8ea36dcc777b2d1bcfb66c4972b6
Salvage debuginfo when combining load and z|s ext instrs.
SelectionDAG uses the DAGCombiner to fold a load followed by a sext to a
load and sext instruction. For example, in x86 we will see that
```
%1 = load i32, ptr @GlobArr
#dbg_value(i32 %1, !43, !DIExpression(), !52)
%2 = sext i32 %1 to i64, !dbg !53
```
is converted to:
```
%0:gr64_nosp = MOVSX64rm32 $rip, 1, $noreg, @GlobArr, $noreg, debug-instr-number 1, debug-location !51
DBG_VALUE $noreg, $noreg, !"Idx", !DIExpression(), debug-location !52
```
The `DBG_VALUE` needs to be transferred correctly to the new combined
instruction, and it needs to be appended with a `DIExpression` which
contains a `DW_OP_LLVM_convert` expression, which correctly casts the
value in the virtual register to the correct size.
This patch fixes the above described problem.
The patch also accounts for multiple DW_OP_LLVM_arg's in a DIExpression
which had caused it to break tests on the sanitizer-x86_64-linux bot but
has now been fixed, with an added testcase called
selectionDAG-load-zext-multiple-args.ll which was reduced from the
broken test itself.

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

Previous use of `Min` for `ptrauth-elf-got` and

decrease of security during module merge. The previous choice for `Min`
was mimicking the behavior for the `sign-return-address*` family of
module flags, but it does not make sense to apply this behavior here.

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

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

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

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

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

[lldb] LLDB_TEST_ARCH -> LLDB_TEST_TRIPLE (#191204)
Change the CMake variable from LLDB_TEST_ARCH to LLDB_TEST_TRIPLE. I'm
working on adding support for cross compiling our test suite to
WebAssembly, where the triple (i.e. `wasm32-wasip1`) is of importance
while building the inferiors. Given that the triple is a superset of the
arch, it is strictly more expressive.

[analyzer][NFC] Document getVarRegion shortcomings (#191168)
... more precisely, that the analyzer currently uses `NonParamVarRegion`
instances to represent parameters of the entrypoint stack frame and
parameters that are captured by inner lambdas or blocks.
In my recent commit f40c234191802154d5b3fc3209908c3f2d6e1649 I added a
FIXME note to the method `MemRegionManager::getVarRegion`, but now, as I
tried to implement that I realized that the situation is more complex.
As I don't have time to fix this right now, I'm pushing this commit to
remove the inaccurate FIXME and replace it with more accurate TODO notes
that explain the current (problematic) behavior of the codebase.

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

express this with a nan propagating operation to start with.

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

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

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

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

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

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

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

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

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

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

Stop using spir_kernel calling convention on non-SPIR targets. (#191090)
This behavior traces back to fc2629a65a05fa05bc5c5bc37cf910c8e41cdac3 ,
but neither the commit message or the reviews actually justify using
this calling convention. The actual behavior which is important for that
change is the way clang calling convention lowering works.
There isn't really any other reason to use spir_kernel: every non-SPIR
target either rejects it, or treats it as the C calling convention. So
let's stop doing it.
Fixes #157028.

[LoopUnrollAndJam] Fix out-of-date LoopInfo being used during unroll and jam (#191250)
Fixed issue #190671, where loop unroll and jam did not update LoopInfo
entirely correctly.
Invalid LoopInfo gets passed into `simplifyLoopAfterUnroll()` and is
further called by SCEV at the beginning of
`ScalarEvolution::createSCEVIter()`, which triggered hidden bugs. To
fix, updated LoopInfo correctly before its use.
The loop blocks that `simplifyLoopAfterUnroll()` iterates
through, will become unavailable after the LoopInfo update. Therefore we
store the loop blocks beforehand for its use in
`simplifyLoopAfterUnroll()` later.

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

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

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

In particular it removes redundant mode changes created as seen

This still relies on the wrong behavior that SETREG updates

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

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

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

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

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

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

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

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

The changes in #168506 and #170547 both have a lifetime issue where an
SDValue is kept for the duration of a function, despite being valid only
when processing the same basic block.
Reverting both on LoongArch and RISC-V as the implementations are
identical and one of the fix commits touches both targets, rather than
doing only a RISC-V revert. I also think this more cleanly shows what is
being undone when starting again with the changes.

[clang-doc] Move non-arena allocated types off the OwnedPtr alias (#190052)
Some types should not be using this alias, which was over applied to
APIs that wont participate in arena style allocation. This patch
restores them to their correct spelling.

[LoopUnroll] Fix out-of-date LoopInfo being used during unroll (#191505)
Loop unroll did not update LoopInfo entirely correctly.
Invalid LoopInfo gets passed into `simplifyLoopAfterUnroll()`, which
could trigger hidden bugs since it is further used by other functions
and components like SCEV. To fix, updated LoopInfo correctly before its
use.
Fixed issue #191036.

Note that the TC in

(12) which is lower than 16 (4 * 4), so the condition of predicated
select are constants.

[clang-doc] Simplify parsing and reading bitcode blocks (#190053)
Much of the logic in the readBlock implementation is boilerplate, and is
repeated for each implementation/specialization. This will become much
worse as we introduce new custom block reading logic as we migrate
towards arena allocation. In preparation for that, we're introducing the
change in logic now, which should make later refactoring much more
straightforward.

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

[Modules] Enrich diags for out of date module dependencies (#190203)
Replace the opaque `ErrorStr` parameter in `ModuleManager::addModule`
with a structured object that carries specific information for
reporting. This allows the diagnostics to emit targeted notes instead of
a single error string appended to the main diagnostic. Information that
is relevant but is tied to implementation details of the compilation is
reported as notes (e.g. signature mismatches)
This patch additionally
* Adds minor comments to places I found unintuitive
* Adds a contrived test case for signature mismatches
* Sets `InputFilesValidation` based on module kind at construction

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

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

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

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

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

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

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

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

Summary:
These relocations are extremely rare, but they are listed as an expected
relocation in https://llvm.org/docs/AMDGPUUsage.html#relocation-records
and you can theoretically make them happen so we should probably support
it in the linker.

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

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

and get an ISEL failure.

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

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

[SLP][REVEC] Fix InsertElement scalar type in getEntryCost
When SLPReVec is enabled, getValueType returns the vector result type
for InsertElement instructions rather than the scalar element type. This
caused getEntryCost to propagate an incorrect ScalarTy (e.g. <4 x float>
instead of float) into getScalarizationOverhead and getWidenedType,
triggering an assertion failure and producing wrong cost estimates.
Narrow ScalarTy to its element type when costing vectorized
InsertElement entries whose inserted operands are scalars.
Fixes #191175.

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

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

I believe that is the intent of SubstIndex in AssociatedConstraint.
So this enforces the checking explicitly, in case nested SubstIndexes

I reverted the previous fix 257cc5ad89840cdfba4affcc8fe62cf9d02d9017
because that was wrong.
As a drive-by fix, this also removes an strange assertion and an
unnecessary
SubstIndex setup in nested requirement transform.
No release note because this is a regression fix.

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

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

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

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

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

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

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

Similar to the DylibManager change in e55fb5de0f9, this removes an
unnecessary coupling between ExecutorProcessControl and MemoryAccess,
allowing clients to select MemoryAccess implementations independently.
To simplify the transition, the
ExecutorProcessControl::createDefaultMemoryAccess method will return an
instance of whatever MemoryAccess the ExecutorProcessControl
implementation had been using previously.

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

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

[libclc] Refine generic __clc_get_sub_group_size with fast full sub-group path (#188895)
Add a fast path for the common case that total work-group size is

The fallback path is ported from amdgpu/workitem/clc_get_sub_group_size.cl.
Compiler can generate predicated instructions for the fallback path to
avoid branches.

This avoids a downstream regression where LSR prefers {-1,+1}.
When constant zero typically doesn't require preheader initialization
(queried via TTI::getIntImmCost), consider it as free in getSetupCost.
Three test changes are improvements: amx-across-func.ll,
2011-11-29-postincphi.ll and pr62660-normalization-failure.ll.
Other test changes are neutral.

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

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

Narrow the new setImplicitDefaultValue() guard so existing default

The previous change was too broad and regressed normal
zero-initialization, causing new int[10]{} to be modeled as undefined
and emit a garbage-value warning instead of the expected analyzer
reports.

[AArch64][SME] Remove SelectionDAG SME ABI lowering (#190950)
This patch removes the `-aarch64-new-sme-abi=<true/false>` option (which
has been defaulted to "true" since LLVM 22), and removes the Selection
DAG lowering for the SME ABI.
There should be no functional changes for the default path
(`-aarch64-new-sme-abi=true`).

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

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

[MLIR][SPIRV] Deduce Shader capability for DescriptorSet/Binding decorations (#188743)
UpdateVCEPass only queried capabilities via QueryCapabilityInterface and
SPIRV type capabilities, but did not check capabilities implied by
decoration attributes on ops. Specifically, the DescriptorSet and
Binding decorations—represented by the `binding` and `descriptor_set`
attributes on `spirv.GlobalVariable`—require the `Shader` capability per
the SPIR-V spec Decoration table, but this was not deduced.
Add an explicit check in UpdateVCEPass: when a `spirv.GlobalVariable`
has a `binding` or `descriptor_set` attribute, require the `Shader`
capability.

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

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

This patch also passes DILMode to the parser to check if binary

alone, because it allows token `*` as a dereference operator for legacy
mode, but that token could also be a binary multiplication allowed only
in full mode.

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

[libc] Add Annex K strnlen_s function (#186112)
This patch adds the `strnlen_s` function from Annex K.
In order to reduce duplication between `strnlen` and `strnlen_s`, the
common logic has been extracted to a new internal function which both
now call.
In addition to the function definition, the patch adds a unit test and a
fuzzing test.

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

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

[GVN] use `AssertingVH` for leaders to improve compilation time (#175870)
Replace the manual check in `verifyRemoved()` with `AssertingVH`
instrumentation. For cases where the leader table becomes very large,
this is a cheaper way to verify we don't have dangling entries in the
leader table.
For this change, we must implement a move constructor for `AssertingVH`
so that we can keep the first entry as an inline-allocated node that
will be handled correctly as the table grows.

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

[ORC] Add MachOPlatform::HeaderOptions customization callback. (#191819)
This change aims to make it easier for MachOPlatform clients to
customize JITDylib MachO headers.
At MachOPlatform construction time clients can now supply a
MachOPlatform::HeaderOptionsBuilder. The supplied callback will be
called by setupJITDylib to create the HeaderOptions for the JITDylib
being set up.
No testcase: Constructing a MachOPlatform instance requires the ORC
runtime, which we can't require for LLVM unit or regression suite tests.
We should look at testing this functionality in the new ORC runtime once
it's ready.

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

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

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

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

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

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

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

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

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

The inner CONCAT_VECTORS result type was hardcoded to MVT::v8i1, which
is only correct when BitBytes == 1. Otherwise, the inner concat produces
fewer elements than 8, causing an assertion failure:
Assertion `(Ops[0].getValueType().getVectorElementCount() * Ops.size())
== VT.getVectorElementCount() && "Incorrect element count in vector
concatenation!"' failed.
Fix by computing the inner vector type dynamically based on BitBytes.

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

[MLIR][Linalg] Fix crash in tileToForallOpImpl for rank-0 ops (#189000)
When tiling a rank-0 linalg.generic op, tileUsingSCF returns an empty
loops vector (rank-0 ops have no parallel dimensions and produce no
scf.forall). Two call sites unconditionally accessed
tilingResult.loops.front(), causing a crash:
- tileToForallOpImpl: the loop normalization block was entered whenever
mixedNumThreads was empty, regardless of whether any loops exist. Guard
it with \!tilingResult.loops.empty().
- TileUsingForallOp::apply: tileOps.push_back was called
unconditionally. Guard it with \!tilingResult.loops.empty().
Add regression tests for both the tile_sizes and num_threads paths,
verifying that the linalg.generic is preserved and no scf.forall is
emitted.

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

[CIR] Exclude _BitInt from fundamental integer type constraints (#191493)
Follow-up to #188113 per @erichkeane's feedback: `isFundamentalIntType`
and `isFundamental()` should not disagree.
The previous patch added `!isBitInt()` only inside
`IntType::isFundamental()`, leaving the underlying TableGen predicates
(`CIR_AnyFundamentalIntType` etc.) unaware of `_BitInt`. That meant
`isSignedFundamental()` and `isUnsignedFundamental()` were silently
wrong — a `_BitInt(32)` would pass them.
This patch adds a `CIR_IsNotBitIntPred` to the three fundamental-int
constraint defs so everything stays consistent. `isFundamental()` now
just forwards to `isFundamentalIntType()` with no extra logic.
Includes an `invalid-bitint.cir` test that checks a `_BitInt(32)` is
rejected where a fundamental unsigned int is required.

LLVM IR coerce type unspecified, implicitly relying on
`CodeGenTypes::ConvertType` to eventually construct a default IR type
based on the struct's layout. This conversion is neither stable nor
guaranteed to adhere to the ABI's classification rules.
Instead, rewrite `classifyRegCallStructTypeImpl` to construct an
explicit sequence of coerce types, using the existing field
classification to obtain a coerce type for each member of the struct.
Also, rename the function to `passRegCallStructTypeDirectly` and return
a boolean instead, so that now `classifyRegCallStructType` is the only
place that computes `ABIArgInfo`.
This rewrite also fixes several other issues with the `X86_64ABIInfo`
implementation of `__regcall`:
* Empty structs are now ignored instead of being misclassified as
direct.
* Arrays are now classified specially based on the element type, since
`X86_64ABIInfo::classifyArgumentType` ignores standalone array types.
* SSE registers used for return values are now correctly reused for
arguments, matching the 64-bit Windows behavior.
Since this is an ABI change, it has the potential to cause
incompatibilities with `__regcall` code compiled by earlier versions of
Clang. Specifically:
* Because SSE return registers can now be reused as argument registers,
functions will now pass more floating point arguments in SSE registers.
* `_Complex float` struct fields are now passed in one SSE register
instead of two.

This doesn't really affect anything as it is a pretty rarely used
feature and thus doesn't appear in the test suite I've seen, but I saw
it while investigating something else.

Add spirv-val compilation step when targeting SPIR-V (#188150)
Clang-dxc.exe currently uses dxv by default after compiling HLSL that
targets DXIL, assuming dxv can be found. However, there is no
counterpart for SPIR-V. This PR changes clang-dxc.exe so that the DXC
driver inserts a step to run spirv-val when SPIR-V is the target. It
also accounts for whether or not the -Fo option is passed. In all cases,
spirv-val will be run, as long as the target is SPIR-V and the spirv-val
executable can be found on the PATH.
This PR also adds a new option --spirv-val-path, a counterpart to
--dxv-path, for specifying an explicit path to spirv-val.
Key differences from dxv: Unlike dxv, which validates and signs DXIL
containers and produces an output file, spirv-val is a pure validator —
it checks the SPIR-V binary and exits with a status code without
producing output. Because of this, the compile step writes directly to
-Fo and spirv-val validates the file in-place.
Additional fixes:
- Fixes a duplicate "validator not found" warning that was emitted twice
per invocation — once from BuildActions and once from isLastJob (via
GetNamedOutputPath). This was a pre-existing bug introduced by #130436
(https://github.com/llvm/llvm-project/pull/130436). Fixed by
adding a Diagnose parameter to requiresValidation so only one call site
emits the diagnostic.
- Fixes an "unused argument" warning for -Vd when targeting SPIR-V,
caused by early returns in requiresValidation before the argument was
claimed.
- Adds a new SPIRVValidation diagnostic group and
warn_drv_dxc_missing_spirv_val diagnostic for the missing spirv-val
warning.

So this commit reverts dd0c5ebe69e580066de100c8c2ba5430a1aeee44 too.
It would've been nice to have to separate revert commits but it seems GitHub won't let me do this and forces commits to be squashed.

[lldb/crashlog] Fix inlined frames in crashlog scripted process (#191132)
When loading a crashlog using scripted process, inlined frames get lost.
This happens because `ScriptedThread::LoadArtificialStackFrames` creates
all frames as concrete frames via `SetFrameAtIndex`, completely
bypassing the inline frame synthesis that
`StackFrameList::FetchFramesUpTo` normally performs using
`GetParentOfInlinedScope`. Since two crashlog frames share the same PC
when one is inlined into the other, `CalculateSymbolContext` resolves
both to the innermost inlined scope, which causes the containing
function to be dropped from the backtrace.
This patch fixes the issue in two parts:
- On the Python side, `resolve_stackframes` now skips frames whose PC
matches the next frame's PC. These are inlined frames that LLDB will
synthesize from debug info when it processes the concrete frames we
provide. Indices are renumbered accordingly, and `len(frames) == 0` is
used for first-frame detection.
- On the C++ side, `LoadArtificialStackFrames` now replicates the inline
synthesis loop from `FetchFramesUpTo`: after creating each concrete
frame, it calls `GetParentOfInlinedScope` in a loop and creates a
`StackFrame` for each inlined parent scope.

[CIR] Implement handling for lambda capture of destructured types (#191316)
Lambda captures of variables that require destruction requires us to
created cleanup scopes with deferred deactivation. That is, the cleanup
scope is created, but added to a list that automatically deactivates the
cleanup when we exit the scope in the compiler code where the lambda is
being generated. This deferred deactivation mechanism will be needed for
other use cases as well, so it is implemented in a general way, which
closely follows the classic codegen handling.

[OpenACC] Fix Crash on collapse that doesn't check its transform (#191836)
GH191833 reports a problem with tree transformation of a collapse clause
when the expression in the clause is invalid. This patch makes sure we
skip out of transforming this clause if it ever encounters an invalid
expression.
I also analyzed the rest of the clauses in this visitor and found 1
other that was suspicious, so I added a check for that one as well. The
rest seemingly were all done correctly.

[AMDGPU] Preserve scoped-AA metadata when lowering barriers to wave_barrier (#191858)
AMDGPULowerIntrinsics downgrades s_barrier/s_barrier_wait to
wave_barrier on single-wave workgroups, but dropped all metadata from
the original instruction. The lost !noalias and !alias.scope metadata
prevented MemorySSA's optimized walker from skipping past the barrier,
causing isClobberedInFunction to walk further and reach unrelated
side-effecting defs (e.g. tensor_load_to_lds) that are misclassified
as clobbers — ultimately losing !amdgpu.noclobber on global loads.
Copy !noalias, !alias.scope, and !tbaa from the old instruction to the
replacement wave_barrier.

[lldb][Darwin] Fetch detailed binary info in chunks (#190720)
When binaries have been loaded into a process on Darwin, lldb sends a
jGetLoadedDynamicLibrariesInfos packet to get the filepath, uuid, load
address, and detailed information from the mach header/load commands.
For a large UI app, the number of binaries that can be loaded (through
various dependencies) can exceed a thousand these days, and requesting
detailed information on all of those can result in debugserver
allocating too much memory when running in constrained environments, and
being killed.
In 2023 I laid the groundwork to fetch detailed information in chunks,
instead of one large request. The main challenge with this is when we
first attach to a process that is running, we send a "tell me about all
binaries loaded", and that prevents lldb from chunking the reply; the
packet design for jGetLoadedDynamicLibrariesInfos assumes the entire
reply is sent in one packet, instead of the typical gdb remote serial
protocol trick of a response with partial data starting with 'm' and a
response with a complete reply starting with 'l'. The 2023 change is to
add a new key to this packet, `report_load_commands` and when that is
set to `false`, only the load address of the binaries is reported.
lldb then uses the array of load addresses of all the binaries to fetch
detailed information about them in smaller groupings.
This PR implements the lldb side of that work.
Process::GetLoadedDynamicLibrariesInfos now takes a `bool
include_mh_and_load_commands`, ProcessGDBRemote sends that as an
argument in the jGetLoadedDynamicLibrariesInfos packet.
DynamicLoaderMacOS::DoInitialImageFetch is changed to only get the load
addresses on initial attach. If the reply includes the full binary
information (not just load addresses) -- when talking to an old
debugserver -- we will use that information instead of re-fetching it.
On a newer debugserver that only sent the load addresses, we'll send
this list of addresses to the standard method we use when dyld has told
us to load binaries at addresses already.
DynamicLoaderMacOS::AddBinaries, which takes a list of addresses and
fetches detailed information about them, is updated to request only 600
binaries at a time. A typical UI app will be in the 700-1000 binary
range these days, so this will turn one large fetch into two, in most
cases. There are some system UI processes that have many dependencies
that could require three fetches. I picked this number so most debug
sessions will be handled by two requests.
In debugserver MachProcess::FormatDynamicLibrariesIntoJSON, I removed
the obsolete-for-three-years-now `mod_date` field. I was sending back
the binary filepaths for this "don't send the detailed information"
version of the packet - I don't need that, and it just increases the
size, so I stopped sending filepaths in this mode.
I also added a new field for when we ARE sending detailed information,
`sizeof_mh_and_loadcmds`. I don't use this in lldb yet, but when we are
told about a binary and need to read it from memory today, we have an
initial read to get the mach header, which tells us the size of the load
commands. Then we have a second read of the mach header plus load
commands, before we can start binary processing in earnest. This is an
extra read packet and very unnecessary, given that debugserver knows how
large the mach header + load commands are. So I'm returning it here, and
at some point I'll find a way to pipe that into a new memory object file
creation method in lldb. It's one of those "I should really find a way
to remove that extra read some day" cleanups, and while I was in this
area, I'd add this first piece of that.
I don't have a test for this. I've been thinking about an API test that
creates 700 dylibs with empty functions in each, runs it, and confirms
all of the dylibs were loaded. I'd have to grab a packet log to be
completely sure we didn't read the full binary list in one go. But I
worry that compiling and linking even 700 do-nothing dylibs might be too
much. Maybe I should add a setting in DynamicLoaderMacOS::AddBinaries to
reduce the maximum number of binaries that can be read at once, and have
a small nubmer of dylibs. When by-hand testing this, I had a maximum of
5 binaries being queried in one packet.

We are seeing test failures in "passthrough-lld.test" as LIT

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

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

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

Updated
[TidyFastCheck.inc](https://github.com/llvm/llvm-project/blob/main/clang-tools-extra/clangd/TidyFastChecks.inc#L1)
that has been stale for a while using this
[script](https://github.com/llvm/llvm-project/blob/main/clang-tools-extra/clangd/TidyFastChecks.py),
as discussed in #190531. In the thread, there was some conversation on
the limitations of doing this manually at every new release (adding the
script to the release checklist would definitely help) but it seems like
this is the only low-risk solution for now.

Add new SelectionDAG pattern matchers for funnel shifts:

- m_FShLLike and m_FShRLike to match:
-- direct FSHL/FSHR nodes
-- ROTL/ROTR equivalents (binding both X and Y to the same rotate operand)
-- OR(SHL(X, C), SRL(Y, BW - C)) forms (including commuted OR)
Also add unit tests covering positive and negative cases for:
- direct funnel-shif matching
- rotate equivalence matching
- OR-based funnel-shift-like patterns

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

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

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

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

about `hidden` it'll be revisited.

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

1. Recognizes `std::function` and `std::move_only_function` as types

origins through both construction and assignment.
2. Adds a kill-only mechanism (i.e., a new `KillOriginFact`) to clear
old loans when the RHS has no origins.

LFI sandboxing during the assembler step.
The initial rewriter handles system instructions: system calls, thread
pointer accesses, and also rejects modifications to reserved registers.

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

As a result of this change, the `UnwindLogMsgVerbose()` is no longer
used and has been removed.

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

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

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

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

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

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

This kind optional is simpler to use when it needs to be represented in
a bitfield, because it has an `unsigned` integer representation which
avoids overflows. This applies to enums as well.
This also adds a single use of this new functionality, migrating users
of `std::optional<NullabilityKind>`
This optional used to be represented as two members in a bitfield, and
this simplifies things down to one.

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

This fixes an error with expensive checks after landing #190139.
The issue was:
Error: comparison doesn't meet irreflexive requirements, assert(!(a <

because it could have previously returned 'true' in the ordering
function if registers A and B were equal.
Also made NFC change to rename 'HandleMatchCmpPredicateHint' ->
'HandleDestructivePredicateHint' (that was missed in the review).

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

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

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

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

Add an InstCombine fold for masked overwrite patterns where the add

(X + C) + (Y & ~C) -> X + (Y | C)
Since `Y & ~C` clears all bits set in C, adding C cannot generate carry
through those bits and is equivalent to setting them with `or`.

[clang] Add support for SerenityOS (#187941)
Adds support for the $arch-unknown-serenity target to the Clang front
end. This makes the compiler look for libraries and headers in the right
places, and enables some security mitigations like stack-smashing
protection and position-independent code by default.
----
A first attempt at upstreaming this patch was made
[here](https://reviews.llvm.org/D154396). I hope I fixed everything
mentioned there.
I intentionally kept `/usr/local/` in the default lookup path. I
consider it the more practical option, and I’d prefer to have the patch
merged as is and revisit the FIXME later. If this is absolutely
unacceptable to the maintainers, I will happily drop it and keep it as a
local patch until we address the underlying issue.
@MaskRay, @brad0 as you already reviewed the original patch.

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

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

This patch implementation is primarily focused on

- Also handled, usage of array variables in the OMP ALLOCATE directive.
- Define omp.allocate_free operation in MLIR and slight changes to existing MLIR definition of ALLOCATOR clause.
- Add test cases for variations of usage of OMP ALLOCATE directive and its clauses ALIGN and ALLOCATOR.

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

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

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

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

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

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

[GlobalISel] use constexpr LLT types when creating ISel data (#191574)
The GlobalISel uses a lookup table to map LLTs which is constructed
prior to initialization of extended LLT functionality, resulting in
ANY_SCALAR entries. During instruction selection, a hash-based
lookup is done on actual INTEGER/FLOAT LLTs. But hash values of
ANY_SCALAR do not match those of INTEGER/FLOAT, causing a failure.
Workaround is the use constexpr LLT, which encodes INTEGER/FLOAT LLT.

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

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

[RISCV][P-ext] Support plui.h/w in generateInstSeqImpl. (#192137)
There's some overlap in the pli/plui encodings. I've modified the code
to prefer pli.b over pli.h and to prefer pli.h over plui.h. This matches
what we do in the splat_vector path in RISCVISelDAGToDAG.

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

This patch enables selecting the Xbox subsystem (IMAGE_SUBSYSTEM_XBOX)

expect images to use the Xbox subsystem, so it's nice to be able to set
this within the LLVM toolchain instead of invoking yet another tool or
manually patching the binaries.

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

CMake 4.x `FindZLIB` may leave `ZLIB_LIBRARY` unset while finding

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

check-${runtime_name} on demand (it may not exist).
This applies regardless of whether the runtime comes from the default

This allows a single `check-${runtime_name}` command to trigger all

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

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

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

[OpenMP] Create check-openmp target for device targets (#192175)
offload/cmake/caches/AMDGPUBot.cmake enables
RUNTIMES_amdgcn-amd-amdhsa_LLVM_ENABLE_RUNTIMES="openmp". In that
sub-build, check-openmp target doesn't exist and there is build error
`unknown target 'check-openmp'` after 18f63d1375d0, which makes
top-level check-openmp depend on check-openmp-amdgcn-amd-amdhsa.
In openmp, the device targets only call add_subdirectory(device), which
doesn't calls construct_check_openmp_target() and check-openmp target
doesn't exist. `ninja check-openmp-amdgcn-amd-amdhsa` also fails with
the same error before 18f63d1375d0.
Fix by adding construct_check_openmp_target() for device targets as well.

[flang][cuda] Fix ignore_tkr(m) to also cover CUDA unified attribute (#192131)
The ignore_tkr(m) directive suppresses CUDA managed attribute checking
on dummy arguments, but it was not covering the unified attribute. This
caused a spurious error when passing a plain host array to a unified
dummy with ignore_tkr(m):
```
error: dummy argument 'x=' has ATTRIBUTES(UNIFIED) but its associated actual argument has no CUDA data attribute
```
Extend the IgnoreTKR::Managed check in AreCompatibleCUDADataAttrs to
accept Unified in addition to Managed and no-attribute.

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

Not all use-sites were updated to pass an argument resulting in build

use formatv instead of expanding the C String, like what is done on
Linux, avoiding the issue entirely.

The HTTP implementation depends on CURL and would preferably not be part
of the LLVM dylib. This was not possible as a nested library under
libSupport, because libSupport itself is part of the LLVM dylib. This
patch moves the HTTP code into a separate top-level library that is
independent from libSupport and excluded from the LLVM dylib.

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

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

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

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

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

[CIR] Handle scalar lowering of qualification-changes (#192152)
Similar to the previous Expr-change that I made, this does the same with

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

[CIR] Lower PsuedoObjectExpr LValues (#192108)
This ends up being pretty much copy/paste from classic-codegen, so it
doesn't have anything particularly novel.
I DID switch the return type of the helper function to be a variant
instead of a manually-put-together pair, and switched to range-for, but
otherwise it should be identical.
However, I was uanble to reproduce a few of the branches, so NYIs were
left in place until we can figure them out. At least some of them are
going to be for RValue versions.

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

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

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

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

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

(Reason: ObjectLinkingLayer's constructor will require a

ExecutionSession has been initialized. Creating a JITLinkMemoryManager
is generally a fallible operation, so we want to be able to bail on
construction of the ObjectLinkingLayer entirely if we can't create a
memory manager for it).

- `x ?= +/-0` && `exp < 0`
- `x ?= finite` && `|exp| > 1`
- `x ?= subnormal` && `exp ?= -1` (special asym case after |exp| > 1)
where `?=` is maybe equal.
It's a bit conservative, and we could refine it further, but I'd take an
iterative improvement.

[CIR] Handle irregular partial init destroy (#192158)
This implements CIR handling for the case where an array of a destructed
type is being initialized using an initializer list and therefore the
address of the last successfully constructed element must be loaded from
a temporary variable before the partial array destroy loop can begin.
In classic codegen this shares its implementation with the general array
ctor/dtor handling, but in CIR we have dedicated operations to abstract
array ctors/dtors, so the implementation of the irregular partial
destruction happens in a different place in codegen.

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

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

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

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

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

This patch improves the ConPTY method that drains the init sequence. It

The previous implementation was prone to race condition, because the
method could return before all the init sequence was received.
This only seems to reproduce on windows-server-2019.

[MachineScheduler] Improve handling of phys regs in GenericScheduler. (NFC). (#187572)
Factor out the handling of coalesced preg COPYs from SystemZMachineScheduler.cpp into MachineScheduler.cpp.
This extends the handling to other types of instructions than COPYs or immediate
loads, such as Load Address and takes care of maintaining the original input
order if both SUs are biased the same way in the same zone.
Another target that uses GenericScheduler can enable this by setting the new
MachineSchedPolicy member BiasPRegsExtra to true (default false). In a derived
scheduling strategy, this could be used either by passing /*BiasPRegsExtra=*/true
to biasPhysReg() (extra instruction detection), or by calling tryBiasPhysRegs()
instead which also preserves the original order if biased the same way.

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

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

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

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

[mlir] Use a container with deterministic iteration order for unrealized materializations (#191323)
Iteration over unrealized materializations in DialectConversion is
non-deterministic as the materialization metadata is stored in a

deterministic behaviour.
This container is iterated for example here:

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

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

[CUDA] Change __CUDACC__ definition to 1 (#189457)
I recently encountered an issue where `nccl` used `#if __CUDACC__` ,
assuming `__CUDACC__` is not only defined but having a #if-able value.
https://github.com/NVIDIA/nccl/blob/v2.28.3-1/src/include/nccl_device/coop.h#L18
Looking at nvcc invocation, I see that:
```
echo "" | nvcc -x cu -E -Xcompiler -dM - | grep __CUDACC__
#define __CUDACC__ 1
```
Changing __CUDACC__ to 1 to match what NVIDIA downstream code

`MemoryEffectOpInterface`. So the main change is the fall-through
path in FIR AA. It should be NFC for Flang.

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

`ModuleManager` doesn't need to consult the file system to obtain this
information, which _might_ be in a different state than when we stored
the PCM file buffer into the in-memory cache.

This change simplifies the level of scopes we build around aggregate
expressions with cleanups and return values involving expressions with
cleanups. This removes unnecessary scopes and lexical scopes that were
created around the expressions and brings the code back into alignment
with the corresponding classic codegen implementation of these handlers.

files, and makes it extensible to support other record formats (potentially in
the future). The environment variables for controlling the recording have also
been modified.

The CSE pass calls `markAnalysesPreserved<DominanceInfo,

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

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

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

[C++20] [Modules] Write comments in C++20 modules' module file (#192398)
Previously we avoid writing the comments in C++20 modules' module file.
But this prevents LSP tools to read the comments in it. Although we
thought to add a new option for it and ask LSP to use the new option,
the cost of comments seems to be low and new option raises complexity,
so I prefer to write comments in C++20 modules' module file by default
now.

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

[clang] Fix crash in isAtEndOfMacroExpansion at FileID boundary. (#191734)
During error recovery, a synthetic token (whose length is 0) can be
inserted past the end of a FileID, e.g. inserting ")" when a macro-arg
containing a comma should be guarded by parentheses.
When calculating the location after this token, the calculated
`AfterLoc` can point exactly to the start of the next FileID
(`NextLocalOffset`), any source manager operations on the `AfterLoc` are
invalid.
This patch adds a safe guard in `Lexer::isAtEndOfMacroExpansion` to
prevent passing this invalid location to `SourceManager`.
Fixes #115007
Fixes #21755

[clang][Parser] Improve error recovery for missing semicolons in class members. (#190744)
This is something I discovered when doing the investigation for
https://github.com/llvm/llvm-project/pull/188123#issuecomment-4162665482.
This patch improves recovery when a semicolon is missing after a class
member declarations.
When the parser expects a semicolon but encounters a token that is at
the start of a line and is a valid declaration specifier, it injects a
`;` instead of skipping tokens, this allows us to preserve the
declaration after the missing ";" instead of discarding it.

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