[LLVM][SelectionDAG] Don't assume masked loads access all lanes in memory. (#192706)
When creating the initial DAG for masked loads we are using the result
type to define LocationSize. However, being a masked load we do not know
which, if any, memory locations will be read.

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

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

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

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

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

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

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

Descriptions are updated to follow the format of most other operations

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

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

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

[MLIR][OpenMP] Unify device shared memory logic, NFCI (#182856)
This patch creates a utils library for the OpenMP dialect with functions
used by MLIR to LLVM IR translation as well as the stack-to-shared pass
to determine which allocations must use local stack memory or device
shared memory.

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

[Flang][OpenMP] Fix crash lowering parallel do with nested tile construct (#193955)
This fixes a crash in OpenMP lowering for cases like `!$omp parallel do
with nested !$omp tile sizes(...)` .
The loop-walk logic now correctly steps through intermediate OpenMP
transformation wrappers to find the actual do construct, instead of
assuming it is directly nested.

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

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

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

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

[Attributor] Support SPIR-V address spaces (#192725)
Right now Attributor assumes that if the the target is a GPU is can use
a single set of address space numerical values to determine the local
address space, but that's not true in general, so add SPIR-V support,
which uses different values.
This fixes an instruction incorrectly being marked as dead and optimized
out for an OpenMP SPIR-V offloading example.

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

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

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

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

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

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

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

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

Break out of the switch so these builtins fall through to the

When a try block has catch handlers but no throwing calls, the handler
regions are unreachable and the TryOp is erased. However, ops inside the

into the parent block, causing an assertion in `eraseOp` ("expected that
op has no uses").
This drops all defined value uses from handler regions before erasing

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

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

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

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

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

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

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

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

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

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

The assertion in `flattenCatchHandler` required `end_catch` to be the

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

Example:

Fix: After multiplying the dynamic extents, also multiply in constant
extents from the type, producing the correct size (`n * m * 4 * 4
bytes`).

[Flang][OpenMP] Add support for scope construct (#193098)
Add support for OpenMP scope construct. The private, reduction, and
nowait clauses (introduced in 5.1) are fully supported. Support for the
firstprivate clause (5.2) is also included. The allocate clause (5.2) is
lowered into the omp.scope MLIR op, but MLIR-to-LLVM IR translation is
not yet implemented.
When nowait is combined with reduction, the reduce function argument to
__kmpc_reduce_nowait is passed as null to prevent the runtime from
selecting the tree reduction method for host, which carries a barrier.

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

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

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

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

SliceSize formula based on E->Scalars.size() no longer matches that

gather-shuffle entries. Use getPartNumElems(VF, NumParts) by default;
fall back to the original-scalars formula only when

[CIR] Implement static-local-tls lowering (#194059)
thread_local variables at function scope work very much like
static-locals, except with slightly different lowering from
cir-lowering-prepare. This patch implements that lowering. Global tls
variables are left to a later patch.
One decision I made here was that LocalInitOp lost its
'static-local'-ness, and assumes it is always static-local. Global TLS
is probably just going to use Global directly, so we don't need to to
permit it.
I DID leave it in the printing, as it makes it more clear what is
happening/for symmetry with get_global/global.

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

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

There was a case where we were creating a GetGlobalOp when initializing
a static local variable that required a guard variable but failing to
set the static_local attribute on the GetGlobalOp. This led to a CIR
verificaiton error. This change sets the attribute when it is needed.

[Sema] Enforce parameter match for ownership_returns attribute (#192339)
Previously parsing multiple ownership_returns attributes with different
arguments could lead to a crash. The documentation states that if
forward declarations have ownership_returns, they must have the same
arguments, and it may appear at most once per declaration.
This patch ensures that if multiple ownership_returns attributes are
present, their arguments (identifier and the optional index) must
exactly match. The diagonstic err_ownership_param_mismatch is introduced
for clarity.
Test cases for f15, C::f, and the newly added f22 were also updated to
match the requirement that all declarations of ownership_returns have
the same arguments, using the err_ownership_param_mismatch diagonstic.
Fixes #188733

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

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

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

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

[RISCV] Remove codegen for vp_zext, vp_sext (#194295)
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 splits off 2 intrinsics from #179622. The vp_truncate combine needs
to be updated to keep the vaaddu patterns for now, but it will be
removed in an upcoming PR.

[asan_abi] Skip new __asan_get_report_* from ABI (#194463)
PR #181446 ("[asan] API for getting multiple pointer ranges") added five
new __asan_get_report_{dealloc,dest,first,second,src}_address entries to
compiler-rt/lib/asan/asan_interface.inc without updating
asan_abi_tbd.txt
or implementing them in compiler-rt/lib/asan_abi/asan_abi.cpp. This
broke
the AddressSanitizerABI-arm64-darwin ::
Darwin/llvm_interface_symbols.cpp
test, which diffs asan_interface.inc (minus asan_abi_tbd.txt) against
the
symbols actually exported by libclang_rt.asan_abi_osx.a.
List the new symbols alongside the existing __asan_get_report_* entries
so the stable-ABI test passes. The symbols remain unimplemented in the
stable ABI library; this change only reflects that they are
intentionally
not part of the stable ABI surface.

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

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

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

The failing builders don't show any output, and the test will be

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

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

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

generic lowering of usub.sat to X - zext(X != 0) in case of aarch64 by
making the constraint of this transformation stricter via an extra
isOperationLegalOrCustom guard on USUBO_CARRY. All other backends will
still receive generic lowering as implemented in the original patch.

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

When the "IgnoredRegex" option is not set, `IgnoredRegexString` is

passed to `llvm_regcomp` as the pattern argument, causing a nullptr+0 UB

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

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

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

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

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

[lldb] Remove full stop from AppendErrorWithFormat format strings (part 2) (#194352)
To fit the style guide:
https://llvm.org/docs/CodingStandards.html#error-and-warning-messages
I found these with:
* Find `(\.AppendErrorWithFormat\(([\s\r\n]+)?"(?:(?:\\.|[^"\\])*))\."`
and replace with `$1"` using Visual Studio Code.
* Putting a call to `validate_diagnostic` in `AppendErrorWithFormat`.
* Manual inspection.
Note that this change *does not* include a call to `validate_diagnostic`
because I do not know what's going to crash on platforms that I haven't
tested on.

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

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

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

[clang][CodeGenCoroutine] Emit missing cleanup scope for lazy GRO conversion (#194281)
In #151067, we promoted GRO ahead of `coro.end`. However, there is a
regression that GRO cleanup might go into coroutine resume and destroy
parts. This patch introduces a dedicated cleanup scope for GRO, ensuring
that GRO cleanup does not interfere with other logic.

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

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

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

```c++
struct R {
struct Inner { constexpr int f() const { return 0; } };
int a = b.f();
Inner b;
};
constexpr R r;
```
because the life time was started by default.
This patch makes record members be `Lifetime::NotStarted` by default
(unless they are primitive arrays) and then starts the lifetime when in
`Pointer::initialize()`.

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

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

[SLP][NFC]Cache IsExternallyUsed by Value in cost computation
Same V is commonly seen in multiple TEs (shared scalars), and the
expensive part of IsExternallyUsed walks V->users() with multiple
match() pattern checks plus per-user getTreeEntries lookups - all
V-only-dependent. Split out the V-dependent body and memoize by
Value pointer, leaving the TE-specific copyable check at the call
site. DeletedNodes is read-only during the cost loop, so caching
is safe.

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

[Lit] Open sub-processes with text=`False` (#194577)

support, and to allow custom in-process builtns to be provided via the

This is part of the Lit daemonized testing project:
https://discourse.llvm.org/t/88612
This PR makes Lit open all sub-processes with `text=False`, so that the
Python code will be able to read and write binary data to and from their
IO streams. This currently causes no functional change, as when Lit
reads output from the sub-processes, it already handles the case that
the read output is `bytes` by decoding it, but we will need to be able
to read binary data from a sub-process's STDIN if its output, which may
be binary, is piped into an in-process built-in, and we will need to be
able to write binary data to a sub-process's STDOUT if its input is
piped from an in-process builtin.
I have made sure that on Windows, when a sub-process invoked by Lit has
its output redirected to a file by Lit, the `\n -> \r\n` conversion is
performed as usual when writing to the file from the process - this
change only affects how the Python code interacts with the streams.

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

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

Since "llvm_unreachable" is actually allowed in constexpr functions,
simply emit the bodies of the selected functions in the header file.
In the previous PR the `isAllowedClauseForDirective` function was made
constexpr, but since it was very long it had a significant impact on
compilation time. In this PR that function is no longer constexpr.

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

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

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

[SLP][NFC]Skip large mostly-trivial trees with up to one vector compute node
Track non-load/store, non-PHI, non-split vector compute nodes separately
in isTreeTinyAndNotFullyVectorizable. Allow skipping a tree when it
contains at most one such vector node and at most one load/store node,
provided the tree is large enough relative to their combined count
(VectorizableTree.size() > LimitTreeSize * (StoreLoadNodes.size() +
VectorNodes.size())).

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