[CIR] Stop marking byval arguments noalias (#220673)
We were putting llvm.noalias on every byval argument. Classic adds it
only under -fpass-by-value-is-noalias, which defaults off, and that
option isn't plumbed into CIR at all, so the right thing is to not emit
it. llvm.noundef stays, since classic does emit that.
Most of the test churn is collapsing LLVM-CIR / LLVM-OGCG prefix pairs
that existed only to record the divergence.

[libunwind] Bound the DWARF expression evaluator operand stack (#220662)
`evaluateExpression` interprets DW_OP_* bytecode against a fixed-size
`pint_t stack[100]` operand stack without checking whether `sp` stays
within array bounds. Malformed or hostile DWARF expressions (such as
those injected via dynamic FDE registration) pushing more than 100
values or underflowing the stack could corrupt the native call stack.
Add bounds checking on `sp` within `evaluateExpression`:
- Bound `sp` to `[&stack[1], &stack[98]]` at each iteration in the
opcode loop, as single-step opcodes push at most 1 value and net-pop at
most 1.
- Add index/depth validation for `DW_OP_pick` and `DW_OP_rot`.
- Ensure `sp >= &stack[1]` on exit from the evaluator.
- Abort execution via `_LIBUNWIND_ABORT` when bounds are violated.
- Add a regression test verifying that an overflowing DWARF expression
aborts safely rather than overflowing the stack.

[clang][DebugInfo] Emit DIProperty for synthesized Objective-C properties (#220362)
Follow-up to #215776, which added `DW_TAG_property` / `DIProperty`
support to LLVM's DebugInfo. This patch teaches Clang's CodeGen to emit
the new `DIProperty` node.
In addition to the legacy `DIObjCProperty` node, `CGDebugInfo` now also
emits a `DIProperty` node whose `backing_storage` points at the ivar a
synthesized property forwards to.
Covered in `clang/test/DebugInfo/ObjC/property-backing-storage.m`:
- `declaredBacking`: `@synthesize` binds to a custom ivar name that IS
declared in the `@interface`.
- `undeclaredBacking`: `@synthesize` binds to a custom ivar name that is
NOT declared; the compiler creates the ivar itself.
- `implicitBacking`: no `@synthesize` at all; the compiler
auto-synthesizes both the accessors and a default-named ivar.

[LowerTypeTests] Support assembly summaries and migrate export tests (#220776)
Update `LowerTypeTestsModule::runForTesting` to read module summaries
using `parseSummaryIndexAssembly` with automatic fallback to YAML.
We need summaries with call graph edges and edge hotness metadata for
upcoming tests (e.g. for jump table layout optimizations). Instead of
extending the custom YAML format, we should use the documented LLVM
assembly format for module summaries (introduced in 08d5b4ef0d08 and
63ee0e73e44e, and documented in LangRef). The text IR summary
representation (`^... = gv: (...)`) natively supports call edges,
hotness types, and function summary attributes.
Migrate all tests that used `-lowertypetests-summary-action=export` with
YAML summary inputs in `Inputs/` to self-contained tests using
`split-file` and text IR summaries. This eliminates the legacy YAML
files
and simplifies the summary representation using omitted default flags
and
tabulated layout.
TODO: Convert the rest of tests (some YAML features are missing from
textual summary assembly) and remove YAML from LowerTypeTests.

[AMDGPU] PromoteAlloca: split scalar accesses that span several elements (#217056)
promoteAllocaToVector already splits a *vector* access across several
elements when it is a multiple of the element size, but a *scalar*
access
had to be bitcastable to the element type, so an i64 load from an alloca
promoted to <8 x i32> was rejected as "not a supported access type" and
the object stayed in scratch.
Accept a scalar access that is a whole multiple of the element size and
route it through the existing subvector path, which already builds the
value from consecutive elements and bitcasts. Accesses with padding are
still rejected, since splitting those would put the pieces at the wrong
offsets, as are non-integer non-float types.

[CIR] Add global offset attribute (#220128)
Previously, if we attempted to compile code that used an offset from a
global variable that created a pointer to outside the global or to a
location that wasn't the exact start of an element of a global
structure, CIR codegen would either assert or hit an unreachable
statement. However, there are legal cases where such an offset can be
used.
This change introduces a new attribute, GlobalOffsetAttr, that provides
a way to describe a raw byte offset from a pointer and uses that
attribute to handle cases where we are unable to compute indices for a
global view attribute.

[AArch64] Lower bitcast of wide <N x i1> masks without a stack spill in more cases (#203420)
vectorToScalarBitmask() lowers `bitcast <N x i1> to iN` to a
register-only movemask, but bailed when the mask's source vector type
`<N x ty>` is wider than 128 bits, leaving the bitcast to legalize
through a stack temporary.
The bail is unnecessary: the bitmask depends only on the lane count and
order, never on the per-lane width. Narrow the per-lane integer width to
128/NumElts bits so the mask fits one 128-bit register and the existing
register-only lowering applies.
Fixes #203414

[Clang] Remove the old LLVM offloading driver entirely (#211924)
Summary:
The 'new' offloading driver is the unified set of steps to produce
merged host and device output. OpenMP offloading has used it by default
since Clang 13, CUDA since Clang 21, and HIP / SYCL since Clang 23. The
support has matured in the 23 release and should now cover the remaining
use-cases.
This PR completely removes the support so we stop needing to support
both when making updates to the driver.

[MLIR][ODS] Default EnumAttr to angle-bracket assembly (#220608)
Make angle brackets the default assembly format for EnumAttr.
Use explicit enum directives where operations retain bare symbolic
syntax.
This is possible now because of the newly added `enum` directive in
#220412 ; which allows to use the raw enum value in the declarative
assembly format, preserving the ability for the enum to use `<` `>`
consistently in the generic form.
You can restore the previous behavior for a given enum attribute with:
```
let assemblyFormat = "$value";
```

macOS 26.3 denies debugserver permission to attach when too many debug
sessions start at once, which surfaces as a test failing with "process
exited with status -1". The denial is intermittent and a rerun normally
gets through.
Gate the rerun on a list of known flake signatures rather than retrying
every failure, because a blanket retry masks real bugs. Adding to that
list is a last resort for defects outside LLDB's control.

[orc-rt] Make ExecutorProcessInfo platform-generic (#220938)
ExecutorProcessInfo was part generic, part system-specific: some of its
methods were implemented directly in its own .cpp, others only existed
as out-of-line definitions in per-OS files under lib/bedrock/sys/.
Move the system-specific pieces into free functions under orc_rt::sys
(mirroring the existing support/sys/ convention), and have
ExecutorProcessInfo consume them like any other client. The class itself
is now fully generic, with no system-specific code of its own.
No functional change, except that page-size detection (previously
hardcoded to POSIX sysconf) now goes through the same per-OS split as
the rest of ExecutorProcessInfo; a Windows implementation is left for a
follow-up.

[LLVMABI] Align RecordType::isEmpty() with Clang's isEmptyRecord()
While working on empty record handling for AArch64, I stumbled across a
couple of differences between the LLVM ABI library's
`RecordType::isEmpty()` and Clang's `CodeGen::isEmptyRecord()`. Testing
verified this led to observable differences in classification when using
the ABI library.
This change updates the ABI library's empty record handling to match
Clang.

[CIR] Add support for coroutine allocation failure (#220466)
This PR adds support for the coroutine promise member function
`get_return_object_on_allocation_failure()`.
When a coroutine fails to allocate its frame, the default behavior is to
throw `std::bad_alloc`. If the promise type defines
`get_return_object_on_allocation_failure()`, the coroutine uses the
nothrow form of `operator new`. If the allocation returns `nullptr`,
`get_return_object_on_allocation_failure()` is called and its return
value is returned to the caller instead of throwing.
One difference from OG is that we reverse the allocation condition. OG
checks whether the allocation was successful and branches to the
initialization path when the allocation succeeds. CIR checks whether the
allocated pointer is `nullptr` and handles the allocation failure case
inside a `cir.if`.

A subscript value is required to be within its bounds only when the
reference is
executed (F'2023 9.5.3.1 paragraph 2), so a reference that never runs
does not
render a program nonconforming. Whether a reference is ever executed
cannot be
determined in general -- consider a procedure whose only call site is in
dead
code, or one that is never called at all -- so rejecting these outright
turns
away conforming programs. Semantics already recognized the narrow case
of a
reference inside a statically false `IF` construct (#174040); this
generalizes
that treatment.
Every other Fortran compiler we have checked accepts this code, so the
previous
behavior blocked migration to Flang. This supersedes the approach in the
first
revision of this PR, which kept the error as the default and added an
opt-in
flag; see also the closed #83011, whose position we now agree with.
### Scope
Covered, and now warnings by default:
- subscripts of variables
- the endpoints of array sections (`a(4:6)` where `a` is `a(5)`)
Deliberately **not** covered, still errors:
- **cosubscripts** -- the requirement is F'2023 9.6 paragraph 2 rather
than
9.5.3.1 paragraph 2, and a cosubscript list determines an image index,
so an
out-of-cobounds constant cosubscript is a materially different situation
- references to a **named constant array** (`Subscript value (0) is out
of range
... in reference to a constant array value`)
- **`DATA` statement designators**
- **substrings**
### User-visible notes
- With the default, an out-of-range subscript inside a statically false
`IF`
construct is now reported as `[-Wout-of-bounds-subscripts]` rather than
`[-Wbad-value-in-dead-code]`, and no longer carries the "in code known
to be
dead due to this compile-time IF expression value" note. No control is
lost:
either `-Wno-` spelling still silences it, and
`-fno-out-of-bounds-subscripts`
restores the previous behavior exactly.
- A module file compiled with the warning can produce errors in a
dependent
compilation that passes `-fno-out-of-bounds-subscripts`, because the
interface
is re-analyzed there; those errors point into the module file.
- `-Wno-out-of-bounds-subscripts` silences the warning entirely.
### Tests
- `flang/test/Semantics/bug82684.f90` -- covers the default, `-fno-`,
and `-Wno-`
modes, plus a section endpoint, and pins the cosubscript /
named-constant /
`DATA` / substring cases as errors in all three modes.
- `flang/test/Driver/fout-of-bounds-subscripts.f90` -- driver-level
coverage of
both spellings, including both orderings to pin down last-wins
precedence.
- `flang/test/Semantics/expr-errors06.f90` and `bug171844.f90` now pass
`-fno-out-of-bounds-subscripts` so they keep testing the error path and
the
downgrade of errors to warnings in code known to be dead.
The motivating pattern, which compiles with other open source and vendor
compilers:
```fortran
module grid_bounds
implicit none
!...choose a 2D or 3D sim by uncomment 1, comment other.
integer, parameter :: n_dims = 2
!integer, parameter :: n_dims = 3
integer, parameter :: extents = 1000

end type
contains
subroutine init_2Dgrid(node)

end subroutine init_2Dgrid
subroutine init_3Dgrid(node)

node%cells(:,1) = 1.0

end subroutine init_3Dgrid
end module grid_bounds
program simul

if (n_dims == 2 ) then
call init_2Dgrid(x)
else

[CIR] Fix a problem with global view index calculation (#221066)
When a global that was declared with an incomplete array type is
replaced by a global with the completed type, the byte offset of each
global view on the old global is recomputed from its indices, and new
indices are derived from that offset. The offset computation rounded its
running total up to the ABI alignment of the record being indexed, which
incorrectly assumes that every member starts at a multiple of its
enclosing record's alignment. That does not hold for a member followed
by padding, so the offset came out too large. The recomputed view then
designated the wrong address or, when the inflated offset no longer
landed on a subelement boundary, fell back to a global offset attribute
holding the wrong offset.

triple as detected by `lli` so that we can mark exception-throwing tests

Adds a -host-jit-triple option to lli to print the value for the

[DebugInfo] Ignore undefined constexpr constructors in constructor homing. (#218165)
The constructor homing optimization limits the amount of redundant debug
info generated for classes by only emitting forward declarations to
debug info in translation units that can't instantiate the class on
their own (i.e. they don't see the definitions of any constructors).
Currently, classes that have _any_ constexpr constructors are excluded
from the optimization. This is being changed to only exclude _defined_
constexpr constructors, as declared constexpr constructors are not
callable in a TU that doesn't see their definition.

[mlir][gpu] Don't request C wrappers for private device functions (#214552)
GPU lowerings attach `llvm.emit_c_interface` to device functions
regardless of visibility. This causes private device functions to
receive external entry points and prevents such functions from being
culled by DCE.
On a real module lowered by a downstream compiler, we measured that
unconditional `llvm.emit_c_interface` inflated the generated PTX by 1.8x
by keeping unused private functions alive and by 7x for pipelines that
also give private functions internal linkage.
This change attaches `llvm.emit_c_interface` only to functions which are
not private for both the gpu->nvvm and gpu->rocdl lowerings. No behavior
change to existing unit tests, and new tests are added to witness the
new behavior for private functions.

[AArch64] Fix missing :lo12: on the catchret address pair (#219200)
`llc -mtriple=aarch64-pc-windows-msvc` emits assembly it cannot assemble
itself.
A function with a `catchret` materialises its continuation block like
this:
```asm
"?catch$2@?0?f at 4HA":
adrp x0, .LBB0_1
add x0, x0, .LBB0_1
ret
```
Pipe that back through `llvm-mc` and you get:
```
error: expected compatible register, symbol or integer in range [0, 4095]
add x0, x0, .LBB0_1
^
```
The `:lo12:` is missing. The CATCHRET expansion in
`AArch64InstrInfo::expandPostRAPseudo()` builds the pair with plain
`.addMBB()`,
so neither operand carries a relocation specifier. This sets `MO_PAGE`
and
`MO_PAGEOFF | MO_NC` on them and teaches `lowerOperand()` to honour a
fragment
flag on a block operand, which is what it already does for every other
symbol
operand.
Two things I got wrong first, in case they come up in review:
- **The flags belong on the MBB operands, not on a symbol.** Rewriting
the pair
with `.addSym()` fixes the printing as well, but it drops the block
reference
and shifts basic-block numbering in
`wineh-catchret-label-generation.ll`.
- **`LowerSymbolOperand()` reads `MO.getOffset()`**, which an MBB
operand does
not have — it asserts. It needs the same guard the neighbouring line
already
carries for jump-table indices, in all three of the ELF/MachO/COFF
paths.
Objects are unaffected: the relocations were always correct
(`PAGEBASE_REL21` + `PAGEOFFSET_12A`), which I checked by assembling the
fixed
output and diffing it against `-filetype=obj`. So this is `-S` /
clang-cl `/FA`
only. It still cost me a night — that is the route you take when a
codegen error
arrives with no source location, and on Windows-on-ARM with C++
exceptions the
route was closed.
Found with clang-cl 23.1.0 building OpenCV for
`aarch64-pc-windows-msvc`.

[mlir][linalg] Preserve cast semantics in named contraction vectorization (#216283)
This patch fixes correctness issues in named contraction vectorization
of Linalg ops whose operands require conversion to an integer
accumulator type.
When `create_named_contraction` is enabled, an op such as `linalg.matmul
{cast = #linalg.type_fn<cast_unsigned>}` was lowered directly to a
mixed-width `vector.contract` without materializing the implied
`arith.extui`. Since `vector.contract` promotes mixed-width integer
operands using sign extension, an `i8 x i8 -> i32` matmul could
interpret unsigned inputs as signed values and produce incorrect
results.
Floating-point operands were similarly passed directly to
`vector.contract` without materializing the `arith.fptosi` or
`arith.fptoui` conversion implied by the Linalg cast semantics.
Materialize `arith.extui` for narrower unsigned integer inputs and
`arith.fptosi` or `arith.fptoui` for floating-point inputs before
constructing the `vector.contract`. Signed integer widening remains
implicit because it matches the promotion semantics of
`vector.contract`.

[Flang] Skip SimplifyIntrinsics for unsigned reductions (#220850)
SimplifyIntrinsics assumes that the reduction argument element type
matches the runtime call result type.
For UNSIGNED reductions, this is not true. For example, MAXVAL on an
UNSIGNED(4) array is lowered with an array element type of ui32, while
the runtime call returns i32 and is converted back to ui32 afterward.
This causes an assertions-enabled build to fail at -O1 and above with:
```
Assertion `*argType == resultType &&
"Argument/result types mismatch in reduction"' failed.
```
The existing simplified integer reduction path is also not safe for
unsigned values. In particular, MAXVAL currently uses a signed minimum
value as the reduction identity and `arith::MaxSIOp` for the comparison.
Instead of weakening the assertion, skip SimplifyIntrinsics when the
input element type is unsigned and preserve the existing runtime call.
This keeps the correct unsigned semantics while leaving signed integer
and floating-point reductions unchanged.

[libc++][pstl] Implementation of parallel std::is_heap_until() based on __parallel_find() (#218603)
This PR adds an implementation of a parallel `std::is_heap_until()`
based on `__parallel_find()`.
The implementation chops the input range `[first+1, last)` into
partitions and processes them in parallel.
For each partition, it derives the first and the last parents of these
children, and iterates over the parents checking their children for heap
violations.
Basically, it's very close to the implementation of the serial version,
but with a different prologue and epilogue.
Part of #99938.

[clang-tidy] Handle auto&& in missing-std-forward (#220164)
Fixes #142660.
`cppcoreguidelines-missing-std-forward` did not diagnose unforwarded
`auto&&` parameters in C++20 abbreviated function templates, even though
equivalent explicitly declared `T&&` parameters were diagnosed.
Abbreviated function templates represent `auto` parameters using an
implicit `TemplateTypeParmDecl`. The existing
`hasDeclaration(templateTypeParmDecl())` matcher does not match this
implicit declaration when traversal ignores implicit nodes.
Remove the redundant declaration matcher so that these parameters are
handled by the existing template type parameter checks.
Add C++20 regression tests covering:
- unforwarded `auto&&`
- correctly forwarded `auto&&`
- `const auto&&`
- mixed `T&&` and `auto&&` parameters

[lld][ELF] Introduce an option to keep data section prefix. (#148985)
https://discourse.llvm.org/t/rfc-profile-guided-static-data-partitioning/83744
proposes to partition a static data section (like `.data.rel.ro`) into
two sections, one grouping the cold ones and the other grouping the
rest.
This change implements section grouping for {`.data.rel.ro`, `.data`,
`.rodata`, `.bss`} to group `.hot` input sections to `.<section>.hot` in
the output and to group `.unlikely` input sections to
`.<section>.unlikely`. The grouping functionality is gated under new lld
option `-z,keep-data-section-prefix`. The mapping for hot ones is
illustrated below.
[bar] is a placeholder to represent optional global variable name below
* `.data.rel.ro.hot.[bar]` => `.data.rel.ro.hot`
* `.data.hot.[bar]` => `.data.hot`
* {`.rodata.hot.[bar]`, `.rodata.str.*.hot.`, `.rodata.cst*.hot.`} =>
.rodata.hot
* .bss.rel.ro => .bss.rel.ro
* .bss.hot.[bar] => .bss.hot
https://github.com/llvm/llvm-project/pull/148920 is a related change
which also introduces lld option `-z,keep-data-section-prefix`. The
option will be introduced once and shared between the two patches.

[clangd] Avoid invalid include-fixer fuzzy-find queries (#212134)
Fixes #200571.
`operator::align_val_t` is parsed as a conversion-function-id, whose
target type is `::align_val_t`. During typo recovery, Sema correctly
passes clangd a `DeclarationNameInfo` with kind
`CXXConversionFunctionName`; it is not a malformed ordinary identifier.
`UnresolvedNameRecorder` previously flattened every
`DeclarationNameInfo` through `getAsString()`. For a conversion-function
name, that presentation string contains the conversion target type and
can therefore contain a qualified type such as `std::align_val_t`. The
recorder then incorrectly stored that string as `UnresolvedName::Name`
and forwarded it as `FuzzyFindRequest::Query`.
Reject only `CXXConversionFunctionName` before this lossy conversion.
Such a name cannot be represented by IncludeFixer's `Name + Scopes`
model: its embedded type qualification is not the scope of an unresolved
symbol. Other special names, such as overloaded operators, retain their
existing behavior because they may be valid unqualified index names.
Add a regression test for the conversion-function recovery path.
Testing: not run after this source-only refinement.

[Transforms][Utils] Strip unnamed_addr on indirect call promotion (#221121)
This patch strips unnamed_addr from the target symbol and vtable when
call promotion introduces an equality comparison.
When promoting an indirect call site, ICP introduces an equality check
comparing the called value against the target:
if (fp == &callee)
callee();
else
fp();
This address comparison makes the callee's address significant. If the
callee symbol has unnamed_addr, AsmPrinter skips emitting it into the
.llvm_addrsig table. Consequently, the linker (under -icf=safe)
considers the symbol safe to merge with another identical function.
This can happen in practice with AutoFDO if an indirect call site is
profiled against an unrelated function whose machine code was folded by
ICF in the profiled binary. ICP then promotes the indirect call against
that wrong symbol. If the linker folds the symbols again, the equality
check evaluates to true at runtime, directing execution into the wrong
branch.
By stripping unnamed_addr from the callee and vtable address points
during promotion, the symbols are recorded in the .llvm_addrsig table
and
kept unique by the linker, preventing safe ICF from merging them.
Thanks to Arthur Eubanks for the idea of stripping unnamed_addr.

[mlir][complex] Avoid cancellation in tanh denominator (#221014)
In ComplexToStandard lowering of `complex.tanh`, the denominator
expansion includes an exponential term:
$\text{denom} = \text{expm1}(2a) + \text{expm1}(-2a) + 4\cos^2(b)$
When $a$ is small, $\text{expm1}(2a) \approx 2a + 2a^2$ and
$\text{expm1}(-2a) \approx -2a + 2a^2$ have opposite signs. Adding them
cancels the leading $\pm 2a$ terms, resulting in loss of precision.
Near poles ($b \approx \pi/2$), $4\cos^2(b)$ vanishes and this
cancellation
dominates the denominator, causing large relative errors in both real
and imaginary parts.
Since $-(e^{2a} - 1)(e^{-2a} - 1) = e^{2a} + e^{-2a} - 2 =
\text{expm1}(2a) + \text{expm1}(-2a)$,
this term can be evaluated via multiplication instead:
$\text{denom} = -\text{expm1}(2a) \cdot \text{expm1}(-2a) + 4\cos^2(b)$
This eliminates cancellation as $a \to 0$ while reusing the pre-existing
$\text{expm1}(2a)$ and $\text{expm1}(-2a)$ values from the numerator
without
requiring additional transcendental evaluations.

[C++20] [Modules] Identify the tag redecl through Using (#221147)
Close https://github.com/llvm/llvm-project/issues/96423
We've already have some logics to merge the redecls. But if the previous
decls are found through using decl, we can't merge them right now. As
the reproducer shows. The using decl is common in modules as a common
method to wrap headers into a module.
The fix is simple too. If the existing check fails, we'll check if the

[LV] Enable the exit value optimization via SCEV for tail folding. (#210928)
Extend optimizeLatchExitIVUserViaSCEV to also match the tail-folding
live-out extraction pattern. This lets the SCEV-based final-value
computation apply under tail folding as well, avoiding unnecessary
vector widening of induction variables that are only used outside the
loop.

[Mips] Fix instruction size for unfinalized bundles (#220953)
It looks like Mips uses unfinalized bundles (i.e. there is no leading

hasDelaySlot() case, things like forbidden slots and load delay slots
are not. Make sure we report the correct size for these.

[SCEV] Propagate a recurrence's nuw flag to its exit value. (#217378)
A recurrence's exit value is its closed form Start + BTC * Step. The sum
does not wrap, if the recurrence does not wrap: the recurrence reached
iteration BTC, so the value it computes there is the value the recurrence
had, and that did not wrap.
The flags are attached to the returned use, because they only apply to
this specific expression we evaluated for the exit value, no other,
equivalent SCEVs.
Alive2 Proof: https://alive2.llvm.org/ce/z/0vSRq-
This on its own has small impact on real world code (only retained some
additional flags in most cases):

the first end-to-end use of SCEVUse.

[AArch64][GlobalISel] Add support for shuffle(v, undef) -> trn(v, v) transformation (#220914)
Stacked PR: 3/3. Preceded by
https://github.com/llvm/llvm-project/pull/220535.
In SDAG, the aarch64-isel phase checks if vector shuffles can be
expressed as trns. To do this, it checks shuffles of type shuffle(v, v),
and shuffle(v, undefined).
GlobalISel previously only checked shuffles of type shuffle(v, v). Add a
check for the situation where one of the operands is undefined.
Notes:
A trn takes two vectors, places the even-indexed elements in the bottom
half, and the odd-indexed elements in the top half.
e.g: `trn <0, 1, 2, 3>, <4, 5, 6, 7> => <0, 4, 2, 6, 1, 5, 3, 7>`.
A trn1 takes the bottom half of the result (aka. the even-indexed
elements)
e.g: `trn1 <0, 1, 2, 3>, <4, 5, 6, 7> => <0, 4, 2, 6>`.
A shuffle is a generic MIR opcode that takes 2 vectors, and places
elements of each into a single vector. The elements are selected based
on a mask.
e.g: `G_SHUFFLE_VECTOR <A, B, C, D>, <E, F, G, H>, <0, 4, 6, 3> => <A,
E, G, D>`.
For certain masks, a shuffle can be represented as a trn.
e.g: ```G_SHUFFLE_VECTOR <A, B, C, D>, <A, B, C, D>, <0, 4, 2, 6>
=> trn1 <A, B, C, D>, <A, B, C, D>
=> <A, A, C, C>```.

[AArch64] Fix vector.match lowering with VLS SVE (#220647)
With `vscale_range()` fixed-vector types > 128-bit can be legal. If
these are used as a `vector.match` needle we still need to split them as
match works per 128-bit segment.
Also, masks such as `v8i1` become legal for types other than i8 and i16,
so we can't assert the source operands are `i8` or `i16`.

[VPlan] Use VPlan-based costs for all integer IVs. (#217766)
Continue the migration of induction costs to be completely VPlan-based.
VPScalarIVStepsRecipe now supports compute its cost for integer
inductions. Skip the legacy precomputeCost code for them.
The main change is that previously we never explicitly accounted for the
canonical IV, which we always generate. It was instead folded into
computing cost of the existing integer IVs with only scalar uses, which
in
most cases are actually served by the canonical IV.
The new code accounts for the cost explicitly, as
VPInstruction::computeCost returns 0 for all recipes w/o underlying
instruction.
Floating point and pointer induction will be handled as follow-ups to
keep the diffs managable and make it easier to track down regressions.
There are a few tests where cost decisions change, but overall they
should be more accurate:
-
llvm/test/Transforms/LoopVectorize/AArch64/conditional-branches-cost.ll:
- partial-reduce-with-invariant-stores.ll
via the legacy cost model, we computed the cost of i64 vector
induction (which has cost of 2/4 for VF 4 and 8), while now we compute
the cost of the generated narrower wide IV and the canonical IV
increment.
- epilogue-vectorization-fix-scalar-resume-values.ll
- predicated-costs.ll
- pr81872.ll
- ARM/optsize_minsize.ll
- X86/conversion-cost.ll
Now also account for the cost of the canonical IV increment
- induction-costs-sve.ll
legacy accounted for scalar increment and extend, now we only account
for the actual canonical IV increment (w/o extend)

factor. It is cleaner to add a separate action type for these operation.

[CIR] Give the cleanup kind a proper standalone attribute spelling (#220878)
CleanupKindAttr overrode its assembly format to a bare `$value` so
`cir.cleanup.scope` would print `cleanup all`. The cost was that the
attribute had no readable standalone form, falling back to
`#cir<cleanup_kind all>`.
The `enum($attr)` operation directive removes the tradeoff. The
attribute
keeps CIR_EnumAttr's bracketed default and now spells
`#cir.cleanup<all>`,
while the operations ask for the bare keyword. The mnemonic drops the
`_kind`
suffix the C++ class name carries.

[LV][AArch64] Provide option to use partial reductions by default (#216001)
Partial reduction intrinsics are explicitly unordered, which may allow
us to perform extra optimizations that may result in a different
ordering of lanes within a vector. This would only be done if the target
indicated the intrinsic was at least as cheap as the normal accumulation
operation.
Off by default to start with.
As an example of an optimization which would be easier/less fragile with
this change, see #206047 which currently tries to match the entire
reduction. If the in-loop update was a partial reduction intrinsic (even
at the same VF), then we could just implement the whole thing as a
DAGCombine.
Some follow-up work will be needed before turning on by default; there's
25 AArch64 check-all failures (just need to update test checks) and some
build failures + regressions in some spec benchmarks to look at.

[RuntimeLibcalls] Add stack protector entries for AVR (#220597)
`__stack_chk_fail` used to be part of the default set of runtime libcall
impls. #148789 moved it out of that set and re-added it explicitly to
each target's `SystemRuntimeLibrary`, and #154930 did the same for the
`__stack_chk_guard` global. `AVRSystemLibrary` was not updated by
either, so both `RTLIB::STACKPROTECTOR_CHECK_FAIL` and
`RTLIB::STACK_CHECK_GUARD` are `RTLIB::Unsupported` on AVR.
Lowering a function with `sspreq` therefore fails twice: loading the
canary reports "unable to lower stackguard", and the failure path dies
in `TargetLowering::makeLibCall` with a `reportFatalInternalError`:
```
$ llc -mtriple=avr ssp.ll
error: unable to lower stackguard
LLVM ERROR: unsupported library call operation
```
Add the two impls directly, as Lanai, MSP430 and Hexagon do. This
restores the pre-#148789 codegen, which referenced `__stack_chk_guard`
and `__stack_chk_fail`.

[clang][Parse] Fix DeclContext reentry to use the template's lexical TU, not the current fragment's TU (#218571)
Problem:
when `-fdelayed-template-parsing` is enabled Instantiating a late-parsed
function template defined in an earlier TU caused an assertion failure
in `clang::Sema::PushDeclContext`:
``DC->getLexicalParent() == CurContext && "The next DeclContext should
be lexically contained in the current one."'`
Fix:
- 1 in `Parser::ParseLateTemplatedFuncDef` obtained the enclosing
`TranslationUnitDecl` called it `LexicalTU`
- 2 changed `GlobalSavedContext` with the `LexicalTU` instead of using
`Actions.Context.getTranslationUnitDecl()`
- in the case that no `LexicalTU` was found fellback to
`Actions.Context.getTranslationUnitDecl()`
Fixes #217073

`do_allocate` has a precondition that the argument is a power of two. We

`do_allocate`s. However, we can assert in `allocate` instead, which has
the added bonus that it's going to be inlined and the check can then
most likely be folded away by the compiler.

[CIR] Print cir.global's TLS model without naked angle brackets (#220879)
`cir.global` printed `tls_model = <tls_dyn>`. Those brackets were the
leftover delimiters of `#cir.tls_model<tls_dyn>` after the printer
stripped
the dialect prefix and mnemonic, so one enum had two spellings and the
per-global one was not something anyone would write by hand.
Wrapping the argument in the `enum` directive prints the symbolic value
on
its own:
cir.global external tls_model = tls_dyn @a = #cir.int<5> : !s32i
The standalone attribute is unchanged.

[CIR][AMDGPU] Add support for AMDGCN cmp and ballot builtins (#198135)
Adds CIRGen for the AMDGCN comparison and ballot builtins:

- __builtin_amdgcn_sicmp
- __builtin_amdgcn_sicmpl
- __builtin_amdgcn_uicmp
- __builtin_amdgcn_uicmpl
- __builtin_amdgcn_ballot_w32
- __builtin_amdgcn_ballot_w64
The cmp builtins are deprecated in favor of ballot_w32 and ballot_w64,
but classic CodeGen still supports them, so CIRGen matches it for
parity. The deprecation is a Sema-level warning and does not affect the
emitted IR.
@ranapratap55 Let me know if you would like a comment noting the
deprecation, either in the implementation or the tests.

[clang] Fix lost lambda capture in dependent co_return operand (#220234)
09231ed02384 ("[clang] Delay dependent co_return promise calls") made
Sema::BuildCoreturnStmt return early for a type-dependent operand,
before reaching the ActOnFinishFullExpr() call that every other path
performs.
Inside a lambda, a reference to a variable of an enclosing function is
not captured immediately: DoMarkPotentialCapture() only records it via
LambdaScopeInfo::addPotentialCapture(), and relies on
ActOnFinishFullExpr() to turn it into an actual capture and odr-use.
Skipping that on the dependent path silently drops the pending capture,
so a variable mentioned only in the operand of a dependent co_return
never gets a capture field. When the generic lambda's call operator is
later instantiated from another context, Sema tries to capture the
variable again and rejects valid code with "reference to local variable
'p' declared in enclosing function".
Finish the full-expression on the dependent path as well.

[mlir][arith] Fold scaling_extf and scaling_truncf with constant operands (#215123)
Add constant folders for the two MXFP scaling casts, mirroring the
expansion
in `ExpandOps.cpp`:
```
scaling_extf(in, scale) -> mulf(extf(in), extf(scale))
scaling_truncf(in, scale) -> truncf(in / extf(scale))
```
Note the asymmetry the expansion already has: `scaling_extf` widens the
scale
to the result type, `scaling_truncf` to the type of `in`.
These were the only two ops in the dialect with neither a folder nor a
canonicalizer, so `-canonicalize` left them alone even with both
operands
constant, while `-arith-expand -canonicalize` folded them away.
Pipelines that
lower them to hardware instructions rather than expanding them, such as
`ArithToAMDGPU` and `XeGPUToXeVM`, never got the fold.
As in `arith.extf` and `arith.truncf`, the widening and narrowing steps
go
through `convertFloatValue` and fold only when lossless, so a
`roundingmode`
on `scaling_truncf` never changes a folded result. Poison propagates and
shaped results are guarded with a static-shape check, as in the generic
folders.
Scales that are not already `f8E8M0FNU` are left alone, because what
such a
scale means is unsettled: the tree does not say whether truncating a
wider
scale to `f8E8M0FNU` rounds or takes its exponent, and `ArithToAMDGPU`
passes
it to an instruction that reads only the exponent. #215295 asks for a
ruling.
The input space of these types is small enough to enumerate, so every
combination was checked against `-arith-expand -canonicalize`, against
the OCP
MXFP semantics computed independently of LLVM, and -- for the decision
to fold
or not -- against the losslessness rule above:
| sweep | cases | folded | disagreements |
| :--- | ---: | ---: | ---: |
| `scaling_extf` f4E2M1FN x f8E8M0FNU -> f16 | 4096 | 656 | 0 |
| `scaling_extf` f4E2M1FN x f8E8M0FNU -> f32 | 4096 | 4096 | 0 |
| `scaling_truncf` f16 x f8E8M0FNU -> f4E2M1FN | 16777216 | 33390 | 0 |

[CIR] Add RegionBranchOpInterface unit tests and fix cir.await successors (#220507)
Adds unit tests for the five CIR ops that implement
`RegionBranchOpInterface`
with no coverage today, and fixes a `cir.await` bug the new tests found:
`verifyControlFlowInterfaceConsistency` fails on `cir.await` today,
because the
op and its own terminator disagree. `cir.condition` terminates the ready
region
and reports `{resume, suspend}` when the parent is an await, while
`AwaitOp::getSuccessorRegions` listed all three regions as entry
successors and
reported the parent op as the successor of every region exit.
The corrected edges match what `cir.condition` already reports:
- from the parent, the only entry successor is `ready`
- from `ready`, the successors are `resume` and `suspend`
- from `suspend` or `resume`, the successor is the parent operation

[CIR] Drop lang_address_space's custom parenthesized attribute format (#220880)
CIR_LangAddressSpaceAttr overrode its assembly format to
`(` custom<AddressSpaceValue>($value) `)`. The parentheses defeated the
dialect's `#cir.mnemonic<...>` syntax, so the attribute printed as
`#cir<lang_address_space(offload_global)>`. It now uses the bracketed
CIR_EnumAttr default and spells
`#cir.lang_address_space<offload_global>`.
The `lang_address_space(x)` spelling inside `!cir.ptr` and `cir.global`
is
unaffected, since that goes through MemorySpaceAttrInterface in
CIRTypes.cpp.
The attribute-level pair in CIRAttrs.cpp was only reachable from the
deleted
format, so it goes away.

[VPlan] Extend cse to eliminate redundant widened loads (#212543)
The generic cse() skips memory-reading recipes, so duplicate widened
loads are never eliminated. Extend cse() to also CSE redundant
VPWiden(EVL)LoadRecipes.
Within a VPBasicBlock, loads are matched against earlier ones with the
same address, mask, scalar type and alignment; the candidate list is cleared
on any memory-writing recipe (a conservative aliasing barrier), so load CSE
stays within a single block. This covers consecutive, masked and gather loads.

-----------
[CodeGen] Don't misinterpret a UINT64_MAX-sized stack object as dead (#220172)
Fixes #214750
A static alloca of `0xFFFFFFFFFFFFFFFF` bytes — what clang emits for
`__builtin_alloca(-1)`, which is valid C — crashed with `Assertion
'!isDeadObjectIndex(ObjectIdx) && "Getting frame offset for a dead
object?"' failed`. MachineFrameInfo encoded dead stack objects in-band
as `Size == ~0ULL`, so this object was considered dead from the moment
it was created: PEI skipped it when assigning frame offsets, but the
frame-index reference was still in the function, and eliminateFrameIndex
asserted when resolving it. No pass ever marked the object dead — the
size itself collided with the sentinel. Not actually a recent regression
despite the label; it reproduces back to 20.x, and GlobalISel had the
identical latent bug since it also feeds the raw alloca size into
`CreateStackObject`.
Deadness is now a separate `isDead` flag on `StackObject` instead of
borrowing a size value, so no size can flip an object's liveness.
`RemoveStackObject` sets the flag, `isDeadObjectIndex` reads it, and the
frame-object debug printer — the only other place that looked at the
sentinel — checks it too. This fixes both instruction selectors at once
rather than clamping the size at each call site. An allocation this
large can never succeed at runtime anyway; a size one byte smaller
already compiled fine through the same path, and now `-1` behaves the
same way. Added `llvm/test/CodeGen/X86/pr214750.ll` covering both the
`-O0` and default pipelines with `-verify-machineinstrs`.
LLM tools were used for this contribution. I've reviewed, built, and
tested the change myself before pushing to GitHub.

[Clang] Clean up leftover old offloading driver tools and utilities (#221093)
Summary:
This PR cleans up some now unused utilities.
1. The old driver fatbinary object building
2. The SDL library linking
3. The offload bundler unbundler job
These are all replaced by operations the new driver does. The one hitch
is that the `--offload-device-only -lfoo -frdc` will not unbundle like
it once did, but I am unsure if that was ever used much in practice.

[CIR] Migrate seven operation enums off IntegerAttr (#220883)
CastKind, DynamicCastKind, CmpOpKind, ComplexRangeKind, InitCatchKind,
CaseOpKind and AwaitKind generated IntegerAttr subclasses. The
operations
printed them symbolically, but in an attribute dictionary `cir.cast
bitcast`
was stored as `kind = 1 : i32`.
Each enum now sets genSpecializedAttr = 0 and gains a CIR_EnumAttr
wrapper,
and the operations wrap the argument in `enum()` to keep the bare
keyword,
giving spellings like `#cir.cast<bitcast>`. Mnemonics drop the suffix
the C++
class name carries.

[lldb][test] Fix flaky results from TestSymStore.py test_http_timeout (#221196)
Fixes #217733.
Observed only on Windows on Arm but I bet it can happen other places.
Sometimes the test would fail because it did not find the error message
in the log file.
The problem is that the test is relying on the client to realise the
timeout has been exceeded and close the connection, before the fake
responder can send back status 200.
So what sometimes happens is:
* The client sends the request.
* The server gets the request and waits N seconds.
* The client is delayed doing other things, and doesn't realise the
timeout has been reached. So the connection is still open.
* The server tries to respond with 200, and that sends succesfully.
* The client wakes up and sees the 200 response, so there's no error to
report.
To fix this, I've changed the responder from merely being slow to never
responding. This means the client can be delayed as long as it likes.
To prevent the responder hanging around, it waits on an event which the
test will set once the test is done (whether pass or fail), then the
responder will shut down normally.
This change does mean that if the client was buggy, we could be waiting
up to the global test timeout. However I think that's a reasonable trade
to not have flaky test results. The alternative is to increase the
responder delay, which will have to vary machine to machine and run to
run. In the end, you'd end up with a delay very similar to the global
test timeout anyway.
This change also narrows the original intent, though not the original
behaviour of the test. We would like to test that the timeout is used,
is accurate, and is configurable. Doing so without flakes is more work
than I'm willing to commit to right now.

[CIR][NFC] Share getSuccessorInputs across region-branch ops (#220509)
All ten CIR ops implementing `RegionBranchOpInterface` hand-wrote
`getSuccessorInputs`, and all ten implementations expressed the same
behavior: regions take no inputs, while returning to the parent yields
the parent’s results.
Three appeared different but were equivalent:
- `CleanupScopeOp` and `CoroBodyOp` unconditionally returned an empty
ValueRange, and neither declares results in ODS.
- `AwaitOp` returned region block arguments, but it carries
`NoRegionArguments`, so those ranges are always empty.
`CIR_RegionBranchOpBase` now declares the method and generates the
shared implementation through extraClassDefinition.

This patch does (hopefully) the infrastructure work to get this running
right.
I asked Claude to help me with the CMake files, and best I can tell it
looks right? But if someone knows better, please let me know. I suspect
we might need to add dependencies along the way as we add new things,
but this seems to work at the moment?
Otherwise, this just moves a handful of trivial utilities that seemed
like a good starting point, plus one I need for CIR right away.

[libc++][pstl] Implementation of parallel std::min_element() based on parallel reduce (#219876)
This PR adds an implementation of parallel `std::min_element()` based on
parallel reduce.
`std::max_element()` is also added, implemented as a "one-liner" over
`min_element`.
The implementation formulates `min_element` as a reduction of iterators
over the input range.
The reduction is provided in two forms: 2-element reduction that picks
the iterator pointing to a smaller value, and a range-based reduction
with init value. The latter delegates the heavy-lifting to the serial
implementation of `std::min_element()`.
Part of #99938.

[X86] Remove TEST after SHL by 1..3 when the shifted operand dies (#220744)
optimizeCompareInstr refuses to reuse the flags of a SHL by 1..3 so that
TwoAddressInstructionPass may still convert the shift into an LEA, which
sets no flags. That conversion exists to avoid a register copy, so it
can only pay off while the shifted operand has further uses; when the
shift is the operand's sole user, the reservation costs a TEST (2-3
bytes and a uop) for nothing. Allow the conversion in that case, as
already done for SHR, SAR, and larger SHL counts.
An x86lint audit of Firefox's libxul.so counted 4,369 redundant TESTs
after immediate shifts, dominated by single-use left shifts by a small
count feeding a compare against zero, e.g. Rust's Layout size checks
(shl $1; test; je). This also composes with dda2c12275e5: 63-bit lowmask
compares shrunken to SHL by 2 now drop their TEST as well.

OpenACC kernels loop.
This peeks through zero-offset FortranObjectViewOpInterface views

[RegisterCoalescer] Do not commute def when a partial def implicitly reads it (#220979)
## Problem
Since f44079db22036d0ade2cf3d2e5a24bde5d378efd, instruction selection
can produce partial register writes (e.g. MOV8rm into sub_8bit) that
implicitly read the rest of the 64-bit register. When
removeCopyByCommutingDef commutes the feeding OR to remove a COPY, it
rewrites only explicit operands and then erases the old definition from
the live interval.
The partial write still implicitly reads that value, so
`JoinVals::analyzeValue` asserts on `Instruction is reading nonexistent
value`.
## Fix
Extend the existing reader check from `use_nodbg_operands` to
`reg_nodbg_operands`, and use `readsReg()` to identify operands that
read `AValNo`. Reject the commute when such a reader is also a def, just
as for a tied use, because it cannot be rewritten independently.
This catches partial defs without introducing a separate scan over all
defs.
## Testing
- New MIR regression test crashes on main (RegisterCoalescer.cpp:2885
assertion) and passes with this change.
- No end-to-end .ll test is included: on the latest HEAD the pass
pipeline no longer takes the branch that triggered the original
assertion.

However, there ARE a few parts that are potentially untested(including

implementation is put in place, as it is a mechanical copy/paste
implementation.
Note: Claude came up with additional test cases.

[flang][NFC] Add FortranObjectLoadOpInterface for load provenance (#221088)
The definition walk in AliasAnalysis::getSourceImpl already keys the
address half of a descriptor access chain on
FortranObjectViewOpInterface (fir.box_addr, fir.create_box,
fir.convert), but the load step was hardcoded to fir::LoadOp. Any other
operation whose result is a value read from memory therefore terminated
the walk at SourceKind::Unknown, losing the AllocDeref/PointerDeref root
and coarsening alias results for everything reached through the loaded
descriptor.
Add FortranObjectLoadOpInterface as the value-producing dual of
FortranObjectViewOpInterface: a view op forwards an address, a load-like
op yields the value read from one. It declares a single getLoadSource
method reporting the memory reference a result was read from. fir.load
implements it as getMemref(), so this is NFC, and the box-load case in
getSourceImpl now keys on the interface instead of the concrete op.
The interface documents provenance only and makes no purity claim, so an
operation whose result depends on more than the contents of the memory
reference can participate as long as it models those extra dependences
through its memory effects. Consumers must not use the interface to
justify value-based transformations such as CSE or load forwarding.

[clang-format] Parse ObjC generics in block literal return types (#220995)
The unwrapped line parser handled a block literal's return type as a
single identifier or type keyword followed by optional stars. A return
type carrying ObjC generics or a protocol qualifier, such as
`^NSArray<NSString *> *(int x) { ... }` or `^id<Proto>(int x) { ... }`,
was therefore not recognized as a block, and its body was treated as a
function body instead. This collapsed the body like a short function
and, with `RemoveSemicolon: true`, dropped the semicolon terminating the
enclosing statement, producing code that no longer compiles.
Skip a balanced angle-bracket list after the return type before looking
for the parameter list and body.

[NFC] [Clang] [CodeGen] Reduce code duplication when emitting trap calls (#221022)
There are a number of places in codegen where we do this:
```c++
llvm::CallInst *TrapCall = EmitTrapCall(llvm::Intrinsic::trap);
TrapCall->setDoesNotReturn();
TrapCall->setDoesNotThrow();
Builder.CreateUnreachable();
Builder.ClearInsertionPoint();
```
This patch adds a helper that does this and updates `EmitTrapCall()` to
no longer create a new block after emitting the trap call.
One test had to be updated because an unnecessary block was dropped.
Before, we were generating this:
```llvm
dtor.call_delete_after_array_destroy: ; preds = %dtor.vector.cont
call void @llvm.trap() #7
unreachable
6: ; No predecessors!
unreachable
```
The second block here is now no longer present, which caused some
instruction renumbering.

-----------
[PseudoProbe] Prevent invalid callsite identities in inline trees (#219079)
Prevent debugless calls in inlined `nodebug` functions from inheriting
the caller's packed pseudo-probe discriminator. Such inheritance aliases
distinct calls onto one probe index and makes the resulting callsite
profile stale. Add a regression test covering the emitted callsite
probe.
Consider:
```
A:
probe #2
call B
B: // nodebug
call C
```
After inlining B into A, LLVM gets:
```
A:
call C
```
Because B has no debug locations, the inliner gives call C the location
of A -> B. That is sensible for debugging: the instruction now appears
at the inlining location.
The problem is that this location also contains pseudo-probe `ID #2`.
That ID identifies the original A -> B callsite. It doesn't mean "code
executing inside A."
Without the fix, call C therefore looks like:
```
call C, debug-location = A's probe #2
```
Later, PseudoProbeInserter sees the packed discriminator and emits a
machine call probe using its encoded function GUID, probe index, and
type.
That creates a false identity:
```
probe (A, #2, DirectCall)
call C
```
But `(A, #2)` describes `A -> B`, not `B -> C`. Samples collected at C
can consequently be attributed to the wrong source callsite and later
appear stale.
The fix retains everything useful while clearing only the
identity-bearing discriminator.
Thus the result is conceptually:
```
call C, debug-location = A's source location,
inline context = preserved,
pseudo-probe identity = none
```
LLVM cannot recover a usable B -> C location here. Because B is nodebug,
it has no DISubprogram, source location, or scope on which to encode its
callsite probe. Synthesizing these would invent debug information and
conflict with nodebug semantics; carrying probe identity independently
would require a broader representation change.
The conservative fix preserves A’s source location, inline context, and
ordinary DWARF base discriminator, while removing the incorrectly
inherited A → B pseudo-probe identity. Having no encoded probe for B → C
is preferable to assigning it a different callsite’s identity.

[CodeGen] Preserve pseudo-probe context when tail merging (#219502)
BranchFolder normally ignores debug locations when deciding whether
machine instructions are identical. That allowed it to merge
`PSEUDO_PROBE `instructions and calls carrying packed pseudo-probe
discriminators even when they came from different inline contexts.
Merging their debug locations then kept only the common outer ancestry,
which moved profile attribution to the wrong callsite.
Keep tail merging enabled, but stop matching at a probe-sensitive
instruction unless both instructions have the same source and inline
context. Call probes also require the same packed discriminator. Tails
from the same probe context remain eligible for merging.
Add MIR coverage for block probes and call probes, including checks that
same-context tails still merge, under both the legacy and new pass
managers.

[Sema] Don't crash filling TypeLoc for a reused AttributedType (#220139)
TypeProcessingState::takeAttrForAttributedType assumed every
AttributedType encountered while filling a declarator's TypeLoc had an
(AttributedType*, Attr*) pair registered earlier in the same
TypeProcessingState's AttrsForTypes.
That assumption doesn't hold when the AttributedType is inherited from
another declarator, for example when __typeof__ reuses a type built for
a different declaration. In that case,
TypeProcessingState::getAttributedType, the function that registers the
pair, is never called.
Return a null Attr* instead of calling llvm_unreachable when no entry is
found. This is the Attr* that AttributedTypeLoc uses for the current
declarator's TypeLoc, and null is right here because the current
declarator never spelled the attribute itself.
Fixes #217489

[lit] Apply --filter-out to GoogleTest shard results (#220410)
[lit] Apply --filter-out to tests expanded from GoogleTest shards
A GoogleTest shard is a single lit test at discovery time, so
`--filter-out` can only match the shard's name and has no way to
deselect individual gtest cases. The cases only get real names once
`post_process_shard_results` expands the shard's JSON output.
Apply the filter there instead: mark expanded subtests whose full name
matches `--filter-out` as EXCLUDED. Record `has_failure_in_shard` before
the filter is applied, so a shard whose only failing cases were filtered
out is still considered accounted for and is not additionally reported as
a failure of the parent shard.
Add a test which filters out the failing and unresolved cases of the
googletest-format inputs and checks that the run reports 2 excluded
and no failures.

[cmake] Fix ninja clean failure for cross-compilation native build dir (#200641)
Ninja clean treats every build OUTPUT as a path to remove(). When NATIVE
(the cross-compilation host sub-build directory) was registered directly
as the OUTPUT of the CREATE_<project>_<target> custom command, ninja
tried to remove() it as if it were a file and failed with "Directory not
empty".
Fixed by introducing a stamp file (NATIVE/created.stamp) as the sole
CMake OUTPUT of that custom command. The stamp file is what ninja cleans
(a single file removal), while make_directory remains idempotent on
subsequent builds.

[OMPIRBuilder] Keep the target construct's location for the deinit call (#221303)
#217407 gave __kmpc_target_init and __kmpc_target_deinit a debug
location by setting the outlined function's location once, before
generating the target body. The init call is emitted before the body and
keeps it, but the deinit call is emitted after, and by then the body may
have replaced it.
The body callback builds the body with its own IRBuilder, so nothing it
emits can disturb the one createOutlinedFunction() uses for the
epilogue. But a body holding another OpenMP construct, a nested parallel
say, calls OpenMPIRBuilder::createParallel, and that leaves the builder
pointing at the wrong debug location, or at none at all. The deinit call
then silently loses its !dbg again.
The test added with #217407 uses a target region whose body is a single
store. Such a body never calls back into OpenMPIRBuilder, the location
survives, and the gap was not visible.
Re-establish the outlined function's location after the body callback,
before emitting the epilogue. The epilogue belongs to the target
construct rather than to whatever the body emitted last, so this is the
location it should carry, and init and deinit go back to agreeing.
Extends the existing test with a nested parallel, which fails on the
deinit check without this change.

[libc] Add CMake formatting utility (#213102)
Added libc/utils/cmake_format.py and libc/utils/cmake_format_test.py to
format LLVM and subproject CMake files according to LLVM-libc formatting
conventions.
The formatter operates in three passes:
* Lexer: Tokenises input using the cmake-language(7) EBNF specification
into typed Token objects with line and column position tracking.
* Dynamic Schema Scanner: Pre-scans repository CMake modules and
function blocks to learn option, single-value, and multi-value keyword
argument schemas from cmake_parse_arguments and set calls.
* Token-Stream Formatter: Applies 2-space control block nesting, keyword
casing, comment buffering, and multi-line list indentation in a single
pass.
The utility supports parallel multi-core execution (-j/--jobs) and
in-place file formatting (-i/--inplace). Added 44 unit tests covering
formatting rules, edge cases, schema scanning, and error diagnostics.

Log Message:
-----------
[clang] Revert "Disable Unique Internal Linkage Names for internal global vars." (#219261)
https://reviews.llvm.org/D98392 "Disable Unique Internal Linkage Names
for internal global vars" in 2021. Summary said "Demanglers do not
recognize clone suffixes for global variables, so disable unique linkage
suffixes until demanglers can be fixed."
Now LLVM's demangler handles suffixed data symbols today:
$ llvm-cxxfilt _ZL8glob_foo.__uniq.123
glob_foo (.__uniq.123)
So reverting the change.
The asm-label exclusion added is preserved and now applies to variables
too: a static variable with an asm label keeps its label verbatim.

Log Message:
-----------
[CIR] Share the underlying-alloca walk with CIRGen
Two copies of this walk existed and disagreed: Address::getUnderlyingAllocaOp
looked through storage-preserving casts, the calling-convention pass did not.
Address.h is private to CIRGen, so the shared copy lands in the dialect as
cir::getUnderlyingAlloca and both call it.
The pass peels casts now, so the alloca it finds is not always the address the
load used. emitStructFieldArgs builds its cir.get_member from that address
instead, and a byref argument read through an address-space cast now gets the
NYI diagnostic rather than being forwarded into a parameter slot in the default
address space.
plainLoad becomes maybeGetSimpleLoad, after LoadInst::isSimple.

Log Message:
-----------
[CIR] Check the inherited-constructor call against classic CodeGen
callInheritedCtor had CIR expectations but no OGCG line, so nothing in the
test showed that classic materializes the same temporary and copies into it.
The alloca and the memcpy go on the shared LLVM prefix, since both backends
agree there. The define line and the two calls stay split, because the
parameter attributes and dead_on_return still differ.
