[AArch64] Decompose FADD reductions with known zero elements (#167313)
FADDV is matched into FADDPv4f32 + FADDPv2i32p but this can be relaxed
when one element (usually the 4th) or more are known to be zero.
Before:
```
movi d1, #0000000000000000
mov v0.s[3], v1.s[0]
faddp v0.4s, v0.4s, v0.4s
faddp s0, v0.2s
```
After:
```
mov s1, v0.s[2]
faddp s0, v0.2s
fadd s0, s0, s1
```
When all of the elements are zero, the intrinsic now simply reduces into
a constant instead of emitting two additions.

[scudo] Change header tagging for the secondary allocator (#182487)
When secondary allocator allocates a new chunk, the allocation is
prepended with a chunk header (common with the primary allocator)
and large header (only used for secondary).
Only the headers are tagged, the data is not, and the headers are
tagged individually as different tags are used for them.
In the current implementation while tagging the large header the unused
area is tagged with it, so the allocator can tag up to a page size (in
worst case), which is costly and does not bring security benefit (as the
area is unused).
With the current fix we can get rid of around 97-98% of the tagging for
the secondary allocator, measured with random benchmarks.

build: correct `MSVC` and Windows mixup for `CLANG_BUILD_STATIC` (#183609)
The build incorrectly used `MSVC` to determine that we were building for
Windows (MS ABI). This prevents the use of the GNU driver for building
LLVM for Windows. Adjust the condition to `WIN32 AND NOT MINGW` to
correctly identify that we are building for Windows MS ABI.

`reallocarray()` is a POSIX extension to C standard which wraps
`realloc` function and adds `calloc`-like overflow detection. It is
available in glibc and some other standard library implementations. Add
`reallocarray` to the list of Scudo C wrappers, so that the code that
depends on `reallocarray` presence will continue to work.

[mlir][arith-to-spirv] Fix null dereference when converting trunci/extui with tensor types (#183654)
`getScalarOrVectorConstInt` only handles `VectorType` and `IntegerType`,
returning `nullptr` for any other type (e.g., a `RankedTensorType` that
slips through after type emulation maps `tensor<Nxi16>` to
`tensor<Nxi32>` with the same destination type). The callers in
`TruncIPattern` and `ExtUIPattern` passed this null value directly to
`spirv::BitwiseAndOp::create`, causing a null-pointer dereference in
`OperandStorage`.
Similarly, the signed-extension pattern passes the result of
`getScalarOrVectorConstInt` as a shift amount to
`ShiftLeftLogicalOp::create` without a null check.
Add `if (\!mask)` / `if (\!shiftSize)` guards that return a match
failure in all three cases, converting the crash into a proper
legalization failure.

[MLIR][Python] Support op adaptor for Python-defined operations (#183528)
Previously, in #177782, we added support for dialect conversion and
generated an `OpAdaptor` subtype for every ODS-defined operation. In
this PR, we will also generate `OpAdaptor` subtypes for Python-defined
operations, so that they can be applied in dialect conversion as well.

[CIR] Remove branch through cleanup fixups (#182953)
Because we are using a structured representation of cleanups in CIR, we
don't need to handle branching through cleanups during codegen. These
branches are created during CFG flattening instead. However, we had
already committed some code that copied the classic codegen behavior for
branching through cleanups. This change deletes that unneeded code.
The most significant change here is that when we encounter a return
statement we emit the return directly in the current location.
The coroutine implementation still creates a return block in the current
lexical scope and branches to that block. Cleaning up that
representation is left as future work.
The popCleanupBlock handling still has a significant amount of logic
that is carried over from the classic codegen implementation. It is left
in place until we can be sure we won't need it.

[LoopUnrollAndJam] Update test dependencies.ll (NFC) (#183509)
Recent on-going works to fix the correctness issues in DA will affect
some existing regression tests for passes that rely on it. As a result,
the original intent of several tests will be lost.
This patch updates `dependencies.ll` to avoid such issues and preserve
its intent. Specifically, this patch changes the loop bounds from
parameters to constants, which allows SCEV to infer no-wrap flags for
the addrecs. Also this patch updates other minor issues in the test,
such as adding pseudo codes and removing some `nuw` to avoid UB.

[LoopUnrollAndJam] Update test unroll-and-jam.ll (NFC) (#183520)
The test `unroll-and-jam.ll` has the following issues:
- Some functions use `%i` and `%I` as variable names, which UTC fails to
distinguish, causing it to update the assertions incorrectly.
- Some tests use parameters for loop bounds, which means they will start
failing in the near future due to the ongoing changes in DA.
To address these issues, this patch updates the test as follows:
- Renames certain variables to avoid the naming conflict.
- For the tests that will be affected by the DA changes, adds variants
with constant loop bounds.

[MLIR][XeGPU] XeGPU Layout adds support for fractional-subgroup-size vector (#183434)
This PR enhances the layout assignment for XeGPU load/store operations
to handle vector size smaller than subgroup size.
Say for vector[4], in case of lane_data=[1], lane_layout=[4] and
inst_data=[4].
The fractional-subgroup-size vector support is required to support the
cross-subgroup reduction case. The number of participant subgroups in
reduction can be small, so it causes each subgroup needs to reduce a
small vector size, often a fraction of subgroup size.
Most layout-based subgroup distribution patterns support
fraction-subgroup-size without no change except a few: reduction,
insert/extract, constant. We don't expect ND operations (like
load_nd/store_nd/dpas) accept fractional-subgroup-size vector.

[Clang][docs] Fix proposal number typo for P1847R4 (#183671)
This PR fixes a typo in `clang/www/cxx_status.html`.
The link text for the feature "Make declaration order layout mandated"
incorrectly referred to **P1874R4**, while the actual URL
(https://wg21.link/p1847r4) and the feature name correctly point to
**P1847R4**.
This change corrects the displayed text to match the proposal number.

[VPlan] Don't drop NUW flag on tail folded canonical IVs (#183301)
After #183080 vscale can no longer be a non-power of 2, which means the
canonical IV can't overflow with tail folding w/ scalable vectors
anymore. Therefore we don't need to drop the NUW flag.
IVUpdateMayOverflow is left to be removed in a separate PR since it
removes further runtime checks.

[LV] NFCI: Move extend optimization to transformToPartialReduction. (#182860)
The reason for doing this in `transformToPartialReduction` is so that we
can create the VPExpressions directly when transforming reductions into
partial reductions (to be done in a follow-up PR).
I also intent to see if we can merge the in-loop reductions with partial
reductions, so that there will be no need for the separate
`convertToAbstractRecipes` VPlan Transform pass.

This reverts commit b0b3e3e1c7f6387eabc2ef9ff1fea311e63a4299.
After thinking about this for a bit, I don't think this is correct.
vscale being a power-of-2 only guarantees the canonical IV increment
overflows to zero, but not overflows in general.

[WebAssembly][FastISel] Emit signed loads for sext of i8/i16/i32 (#182767)
FastISel currently defaults to unsigned loads for i8/i16/i32 types,
leaving any sign-extension to be handled by a separate instruction. This
patch optimizes this by folding the SExtInst into the LoadInst, directly
emitting a signed load (e.g., i32.load8_s).
When a load has a single SExtInst use, selectLoad emits a signed load
and safely removes the redundantly emitted SExtInst.

renamed to `enqueueStmtNodes` to highlight that it just calls

[AArch64] optimize vselect of bitcast (#180375)
Using code/ideas from the x86 backend to optimize a select on a bitcast
integer. The previous aarch64 approach was to individually extract the
bits from the mask, which is kind of terrible.
https://rust.godbolt.org/z/576sndT66
```llvm
define void @if_then_else8(ptr %out, i8 %mask, ptr %if_true, ptr %if_false) {
start:
%t = load <8 x i32>, ptr %if_true, align 4
%f = load <8 x i32>, ptr %if_false, align 4
%m = bitcast i8 %mask to <8 x i1>
%s = select <8 x i1> %m, <8 x i32> %t, <8 x i32> %f
store <8 x i32> %s, ptr %out, align 4
ret void
}
```
turned into

```
So substantially shorter. Instead of building the mask
element-by-element, this approach (by virtue of not splitting) instead
splats the mask value into all vector lanes, performs a bitwise and with
powers of 2, and compares with zero to construct the mask vector.

users may already get a non-const MemoryAccess pointer via
`getMemoryAccess` for a given instruction. Drop the restriction
on directly iterate over them by modifying public `getBlockDefs`/
`getBlockAccesses` APIs to return a mutable list, thus dropping the
now obsolete distinction with `getWritableBlockDefs` and
`getWritableBlockAccesses` helpers.

[mlir][affine] Fix crash in linearize_index fold when basis is ub.poison (#183650)
`foldCstValueToCstAttrBasis` iterates the folded dynamic basis values
and erases any operand whose folded attribute is non-null (i.e., was
constant- folded). When an operand folds to `ub.PoisonAttr`, the
attribute is non-null so the operand was erased from the dynamic operand
list. However, `getConstantIntValue` on the corresponding `OpFoldResult`
in `mixedBasis` returns `std::nullopt` for poison (it is not an integer
constant), so the position was left as `ShapedType::kDynamic` in the
returned static basis.
This left the op in an inconsistent state: the static basis claimed one
more dynamic entry than actually existed. A subsequent call to
`getMixedBasis()` triggered the assertion inside `getMixedValues`.
Fix by skipping poison attributes in the erasure loop, treating them
like non-constant values. This keeps the dynamic operand and its
matching `kDynamic` entry in the static basis consistent.

[mlir][dataflow] Fix crash in IntegerRangeAnalysis with non-constant loop bounds (#183660)
When visiting non-control-flow arguments of a LoopLikeOpInterface op,
IntegerRangeAnalysis assumed that getLoopLowerBounds(),
getLoopUpperBounds(), and getLoopSteps() always return non-null values
when getLoopInductionVars() is non-null. This assumption is incorrect:
for example, AffineForOp returns nullopt from getLoopUpperBounds() when
the upper bound is not a constant affine expression (e.g., a dynamic
index from a tensor.dim).
Fix this by checking whether the bound optionals are engaged before
dereferencing them and falling back to the generic analysis if any bound
is unavailable.

now canonical IVs that are unrolled will have steps that don't overflow,
so we can add the nuw flag.
This allows us to tighten the VPlanVerifier isKnownMonotonic check by
restricting it to adds with nuw.

[analyzer] Fix crash in MallocChecker when a function has both ownership_returns and ownership_takes (#183583)
When a function was annotated with both `ownership_returns` and
`ownership_takes` (or `ownership_holds`), MallocChecker::evalCall would
fall into the freeing-only branch (isFreeingOwnershipAttrCall) and call
checkOwnershipAttr without first calling MallocBindRetVal. That meant no
heap symbol had been conjured for the return value, so
checkOwnershipAttr later dereferenced a null/invalid symbol and crashed.
Fix: merge the two dispatch branches so that MallocBindRetVal is always
called first whenever ownership_returns is present, regardless of
whether the function also carries ownership_takes/ownership_holds.
The crash was introduced in #106081
339282d49f5310a2837da45c0ccc19da15675554.
Released in clang-20, and crashing ever since.
Fixes #183344.

[X86] Fold XOR of two vgf2p8affineqb instructions with same input (#179900)
This patch implements an optimization to fold XOR of two
`vgf2p8affineqb` instructions operating on the same input.
This optimization:
Reduces instruction count from 3 to 2
Eliminates one vgf2p8affineqb instruction
Added combineXorWithTwoGF2P8AFFINEQB function in X86ISelLowering.cpp
Uses sd_match pattern matching for consistency with existing code
Checks that both operations have single use to avoid code bloat
Verifies both operations use the same input
Handles commutative XOR patterns automatically

[AMDGPU][Scheduler] Add `GCNRegPressure`-based methods to `GCNRPTarget` (#182853)
This adds a few methods to `GCNRPTarget` that can estimate/perform RP
savings based on `GCNRegPressure` instead of a single `Register`,
opening the door to model/incorporate more complex savings made up of
multiple registers of potentially different classes. The scheduler's
rematerialization stage now uses this new API.
Although there are no test changes this is not really NFC since register
pressure savings in the rematerialization stage are now computed through
`GCNRegPressure` instead of the stage itself. If anything this makes
them more consistent with the rest of the RP-tracking infrastructure.

[mlir][tensor] Fix crash in tensor.from_elements fold with non-scalar element types (#183659)
The fold for tensor.from_elements attempted to always produce a
DenseElementsAttr by calling DenseElementsAttr::get(type, elements).
However, DenseElementsAttr::get only handles basic scalar element types
(integer, index, float, complex) directly. For other element types such
as vector types, it expects StringAttr (raw bytes) for each element,
which folded constants won't provide — triggering an assertion.
Fix this by guarding the fold: only attempt the DenseElementsAttr fold
when the tensor element type is integer, index, float, or complex.

[mlir][transforms] Fix crash in remove-dead-values when function has non-call users (#183655)
`processFuncOp` asserts that all symbol uses of a function are
`CallOpInterface` operations. This is violated when a function is
referenced by a non-call operation such as `spirv.EntryPoint`, which
uses the function symbol for metadata purposes without calling it.
Fix this by replacing the assertion with an early return: if any user of
the function symbol is not a `CallOpInterface`, skip the function
entirely. This is safe because the pass cannot determine the semantics
of arbitrary non-call references, so it should leave such functions
alone.

Discussion is a follow-up from
https://github.com/llvm/llvm-project/issues/182762#issuecomment-3965207289
(where we're discussing how LLDB could make use of this symbol for
vtable detection).
`_vtable$` is not a reserved identifier in C or C++. In order for
debuggers to reliably use this symbol without accidentally reaching into
user-identifiers, this patch renames it such that it is reserved. The
naming follows the style of the recently added `__clang_trap_msg`
debug-info symbol.

Your comparator is not a valid strict-weak ordering
printf-debugging revealed that symbols like "?ST@@3JA" were not
comparing equal with themselves. It turns out the comparison was done
with
return S1.compare_insensitive(S2.data());
and even when &S1 == &S2, S1 and S2.data() may not refer to identical
strings, since data() may not have a null terminator where the StringRef
locally ends.
This fixes the ordering, simplifies the code, and makes it a little
faster :)

[VPlan] Remove manual region removal when simplifying for VF and UF. (#181252)
Replace manual region dissolution code in
simplifyBranchConditionForVFAndUF with using general
removeBranchOnConst. simplifyBranchConditionForVFAndUF now just creates
a (BranchOnCond true) or updates BranchOnTwoConds.
The loop then gets automatically removed by running removeBranchOnConst.
This removes a bunch of special logic to handle header phi replacements
and CFG updates. With the new code, there's no restriction on what kind
of header phi recipes the loop contains.
Note that VPEVLBasedIVRecipe needs to be marked as readnone. This is
technically unrelated, but I could not find an independent test that
would be impacted.
The code to deal with epilogue resume values now needs updating, because
we may simplify a reduction directly to the start value.

[ThinLTO] Reduce the number of renaming due to promotions (#178587)
Currently for thin-lto, the imported static global values (functions,
variables, etc) will be promoted/renamed from e.g., foo() to
foo.llvm.<hash>(). Such a renaming caused difficulties in live patching
since function name is changed ([1]).
It is possible that some global value names have to be promoted to avoid
name collision and linker failure. But in practice, majority of name
promotions can be avoided.
In [2], the suggestion is that thin-lto pre-link decides whether
a particular global value needs name promotion or not. If yes, later on
in thinBackend() the name will be promoted.
I compiled a particular linux kernel version (latest bpf-next tree)
and found 1216 global values with suffix .llvm.<hash>. With this patch,
the number of promoted functions is 2, 98% reduction from the
original kernel build.
If some native objects are not participating with LTO, name promotions
have to be done to avoid potential linker issues. So the current
implementation cannot be on by default. But in certain cases, e.g., linux kernel
build, people can enable lld flag --lto-whole-program-visibility to reduce the
number of functions like foo.llvm.<hash>().
For ThinLTOCodeGenerator.cpp which is used by llvm-lto tool and a
few other rare cases, reducing the number of renaming due to promotion,
is not implemented as lld flag '-lto-whole-program-visibility' is not supported
in ThinLTOCodeGenerator.cpp for now. In summary, this pull request
only supports llvm-lto2 style workflow.

This should improve the overall performance of the tests, locally they

[clang][modules] Prevent deadlock in module cache (#182722)
When there's a dependency cycle between modules, the dependency scanner
may encounter a deadlock. This was caused by not respecting the lock
timeout. But even with the timeout implemented, leaving
`unsafeMaybeUnlock()` unimplemented means trying to take a lock after a
timeout would still fail and prevent making progress. This PR implements
this API in a way to avoid UB on `std::mutex` (when it's unlocked by
someone else than the owner). Lastly, this PR makes sure that
`unsafeUnlock()` ends the wait of existing threads, so that they don't
need to hit the full timeout amount.
This PR also implements `-fimplicit-modules-lock-timeout=<seconds>` that
allows tweaking the default 90-second lock timeout, and adds `#pragma
clang __debug sleep` that makes it easier to achieve desired execution
ordering.

[mlir][vector] Fix crashes in MaskOp::fold and CanonializeEmptyMaskOp (#183781)
Two related crashes were fixed in vector.mask handling:
1. MaskOp::fold() crashes with a null pointer dereference when the mask
is all-true and the mask body has no maskable operation (only a
vector.yield). getMaskableOp() returns nullptr in this case, and the
fold was calling nullptr->dropAllUses(). Fixed by returning failure()
when there is no maskable op, deferring to the canonicalizer.
2. CanonializeEmptyMaskOp creates an invalid arith.select when the mask
type is a vector (e.g., vector<1xi1>) but the result type is a scalar
(e.g., i32). arith.select with a vector condition requires the value
types to be vectors of the same shape. Fixed by bailing out when any
result type doesn't match the mask shape.
Regression tests are added for both cases.
Fixes #177833

[flang-rt] Enable more runtime functions for the GPU target (#183649)
Summary:
This enables primarily `stop.cpp` and `descriptor.cpp`. Requires a
little bit of wrangling to get it to compile. Unlike the CUDA build,
this build uses an in-tree libc++ configured for the GPU. This is
configured without thread support, environment, or filesystem, and it is
not POSIX at all. So, no mutexes, pthreads, or get/setenv.
I tested stop, but i don't know if it's actually legal to exit from
OpenMP offloading.

Reapply "[ValueTracking] Propagate sign information out of loop" (#182512)
LLVM converts sqrt libcall to intrinsic call if the argument is within

not able to deduce the non-negativity on its own. Extended ValueTracking

[flang] [flang-rt] Addition of the Fortran 2023 TOKENIZE intrinsic. (#181030)
This implements the TOKENIZE intrinsic per the Fortran 2023 Standard.
TOKENIZE is a more complicated addition to the flang intrinsics, as it
is the first subroutine that has multiple unique footprints. Intrinsic
functions have already addressed this challenge, however subroutines and
functions are processed slightly differently and the function code was
not a good 1:1 solution for the subroutines. To solve this the function
code was used as an example to create error buffering within the
intrinsics Process and select the most appropriate error message for a
given subroutine footprint.
A simple FIR compile test was added to show the proper compilation of
each case. A thorough negative path test has also been added, ensuring
that all possible errors are reported as expected.

[mlir][LLVM] Let decomposeValue/composeValue handle aggregates (#183405)
This commit updates the LLVM::decomposeValue and LLVM::composeValue
methods to handle aggregate types - LLVM arrays and structs, and to have
different behaviors on dealing with types like pointers that can't be
bitcast to fixed-size integers. This allows the "any type" on
gpu.subgroup_broadcast to be more comprehensive - you can broadcast a
memref to a subgroup by decomposing it, for example.
(This branched off of getting an LLM to implement
ValueuboundsOpInterface on subgroup_broadcast, having it add handling
for the dimensions of shaped types, and realizing that there's no
fundamental reason you can't broadcast a memref or the like)

[WebAssembly] Incorporate SCCs into WebAssemblyFixIrreducibleControlFlow (#181755)
Rather than mapping out full "reachability" between blocks in a region
to find loops and using `LoopBlocks` to find the bodies of said loops,
use SCCs (strongly-connected components) to provide this information.
This brings in LLVM's generic `SCCIterator` (which uses Tarjan's
algorithm) as the implementation for sorting the basic blocks of the CFG
into their SCCs.
This PR greatly reduces the compile-time footprint of the pass, making
memory use and time taken negliable where it might have previously
caused stalls and OOM before (e.g. #47793,
usagi-coffee/tree-sitter-abl#114)

Fixes #165041 (probably)
Thanks to @jkbz64 for the initial investigations (w/ AI; see #179722)

were the key.
Also thanks to the Cheerp compiler project for bringing `SCCIterator` to
light in this context ([blog

[SlotIndexes] Further pack indices to improve spill placement time (#182640)
This patch makes it so that renumbering indices when inserting
instructions into the SlotIndexes analysis renumbers the entire list if
the list is otherwise densely packed. This fixes a case we saw on
AArch64 with a lot of spills where every single spill instruction
insertion required a renumbering of most of the instructions in a large
function, making the operation approximately quadratic.
This is not NFC as heuristics depend on the SlotIndex numbers, although
this should mostly be a wash as LRs should be extended ~equally.

`JSONFormat` support for `TUSummary`. Duplication of tests has been
avoided by parameterizing the test fixture that runs all relevant
read/write tests against `TUSummary`, for `TUSummaryEncoding`. This
ensures that the two serialization paths remain in lockstep.

[SLP] Reject duplicate shift amounts in matchesShlZExt reorder path (#183627)
In the reordered RHS path of matchesShlZExt, the code never checked that
each shift amount (0, Stride, 2×Stride, …) appears at most once. When
the same shift appeared in multiple lanes, it still filled Order,
producing a non-permutation (e.g. Order = [0,0,0,1]). That led to bad
shuffle masks and miscompilation (e.g. shuffles with poison).
The patch adds an explicit duplicate check: before setting Order[Idx] =
Pos, it ensures Pos has not been seen before, using a SmallBitVector
SeenPositions(VF). If a position is seen twice, the function returns
false and the optimization is not applied.

[InstCombine] Replace alloca with undef size with poison instead of null (#182919)
InstCombine previously replaced an alloca instruction with a null
pointer when the array size operand was undef. While this replacement
may be legal, it still caused invalid IR in cases where the original
alloca was used by `@llvm.lifetime` intrinsics.
The spec requires that the pointer operand of `@llvm.lifetime.*` must be
either:
- a pointer to an alloca instruction, or
- a poison value.
Replacing the pointer with null violated this requirement and triggered
verifier errors.
These new changes update InstCombine so that in this scenario the alloca
is replaced with poison instead of null.

[Clang][ItaniumMangle] Fix recursive mangling for lambda init-captures (#182667)
[Clang][ItaniumMangle] Fix recursive mangling for lambda init-captures
Mangle computation for lambda signatures can recurse when a call
operator type
references an init-capture (for example via decltype(init-capture)). In
these
cases, mangling can re-enter the init-capture declaration and cycle back
through
operator() mangling.
Make lambda context publication explicit and independent from numbering
state,
then use that context uniformly during mangling:
* Publish lambda `ContextDecl` in `Sema::handleLambdaNumbering()` before
numbering, so dependent type mangling can resolve the lambda context
without
recursing through the call operator.
* Introduce `CXXRecordDecl::setLambdaContextDecl()` and remove
`ContextDecl`
from `CXXRecordDecl::LambdaNumbering`.
* Update `ASTImporter` to import/set lambda context separately from
numbering.
* In Itanium mangling, derive init-capture handling from context
computation:
- map local-lambda init-captures to the enclosing local context in
`getEffectiveDeclContext()`
- support init-capture variables in `getClosurePrefix()`
- keep `mangleLocalName()` generic and rely on the computed context
Add mangling regression coverage in mangle-lambdas.cpp, including:
* local init-captures used through decltype
* non-local variable-template init-captures in decltype
* non-local static inline member init-captures in decltype

[alpha.webkit.NoDeleteChecker] Check if each field is trivially destructive (#183711)
This PR fixes the bug that NoDeleteChecker and trivial function analysis
were not detecting any non-trivial destruction of class member
variables.
When evaluating a delete expression or calling a destructor directly for
triviality, check if each field in the class and its base classes is
trivially destructive.

[clang][modulemap] Lazily load module maps by header name (#181916)
After header search has found a header it looks for module maps that
cover that header. This patch uses the parsed representation of module
maps to do this search instead of relying on FileEntryRef lookups after
stating headers in module maps.
This behavior is currently gated behind the
`-fmodules-lazy-load-module-maps` `-cc1` flag.

[mlir][cf] Fix crash in simplifyBrToBlockWithSinglePred when branch operand is a block argument of its successor (#183797)
When `simplifyBrToBlockWithSinglePred` merges a block into its sole
predecessor, it calls `inlineBlockBefore` which replaces each block
argument with the corresponding value passed by the branch. If one of
those values is itself a block argument of the successor block, the call
`replaceAllUsesWith(arg, arg)` is a no-op. Any uses of that argument
outside the block (e.g. in a downstream block) are therefore not
replaced, and when the successor block is erased the argument is
destroyed while those uses are still live, triggering the assertion
`use_empty() && "Cannot destroy a value that still has uses\!"` in
`IRObjectWithUseList::~IRObjectWithUseList`.
Guard against this by returning early when any branch operand is a block
argument owned by the destination block.
Fixes #126213

* Update IndexCastOp and IndexCastUIOp to declare
`ArithExactFlagInterface`
* Update canonicalization patterns

* String parsing and encoding have bugs fixed
* CLI args are updated, primarily to support an output file
* Added uleb encoding/decoding support
This work is a prelude the ongoing work of a Python to formatter
bytecode compiler. The python compiler to emit assembly, and this module
(formatter_bytecode) will compile it into binary bytecode.

[NFC] Fix use-after-free: track TargetLibraryAnalysis in BasicAAResult invalidation (#183852)
`BasicAAResult` holds a reference to `TargetLibraryInfo` but its
`invalidate()` function did not check `TargetLibraryAnalysis`. When the
pass manager destroyed and re-created `TLI` (e.g. during `CGSCC`
invalidation or `FAM.clear()`), `BasicAAResult` survived with a dangling
`TLI` reference.
This was exposed by #157495 which added `aliasErrno()`, the first code
path that dereferences `TLI` from `BasicAAResult` during the `CGSCC`
pipeline, causing a AV when compiling Rust's core library on Arm64
Windows.
This change adds `TargetLibraryAnalysis` to the invalidation check so
`BasicAAResult` is properly invalidated when its `TLI` reference becomes
stale.

[lldb] Change the way the shlib directory helper is set (#183637)
This PR changes the way we set the shlib directory helper. Instead of
setting it while initializing the Host plugin, we register it when
initializing the Python plugin. The motivation is that the current
approach is incompatible with the dynamically linked script
interpreters, as they will not have been loaded at the time the Host
plugin is initialized.
The downside of the new approach is that we set the helper after having
initialized the Host plugin, which theoretically introduces a small
window where someone could query the helper before it has been set.
Fortunately the window is pretty small and limited to when we're
initializing plugins, but it's less "pure" than what we had previously.
That said, I think it balances out with removing the plugin include.

solved this problem by passing a list of values to spill and reload to
forceCleanup(). This change implements that same solution for CIR.
I have also aligned the ScalarExprEmitter::VisitExprWithCleanups
implementation with that of classic codegen, eliminating an extra
lexical scope. This causes temporary allocas to be created at the next
higher existing lexical scope, but I think that's OK since they would be
hoisted there anyway by a later pass.

[CMake] Propagate dependencies to OBJECT libraries in `add_llvm_library` (#183541)
Previously, transitively inherited calls to
`target_include_directories(foo SYSTEM ...)` were being squashed into a
flat list of includes, effectively stripping off `-isystem` and
unintentionally forwarding warnings from such dependencies.
To correctly propagate `SYSTEM` dependencies, use
`target_link_libraries` to forward the parent target's link dependencies
to the OBJECT library (similar to the `_static` flow below). Unlike a
flat `target_include_directories`, this lets CMake resolve transitive
SYSTEM include directories through the proper dependency chain.
Note that `target_link_libraries` on an OBJECT library propagates all
usage requirements, not just includes. This also brings in transitive
`INTERFACE_COMPILE_DEFINITIONS`, `INTERFACE_COMPILE_OPTIONS`, and
`INTERFACE_COMPILE_FEATURES`. This is arguably more correct, as the
OBJECT library compiles the same sources and should see the same flags.
The existing `target_include_directories` call is retained for include
directories set directly on the target (not through link dependencies).
CMake deduplicates include directories that appear through both paths.
Compile definitions and options may technically appear twice (once via
the OBJECT library, once via the consuming target), but duplicate `-D`
and flag entries should be harmless in practice.
Also fix `clang_target_link_libraries` and `mlir_target_link_libraries`
to forward the link type (PUBLIC/PRIVATE/INTERFACE) to `obj.*` targets.
Previously the type keyword was silently dropped, resulting in
plain-signature `target_link_libraries` calls. This is now required
because the new keyword-signature call in `llvm_add_library` would
otherwise conflict (CMake requires all calls on a target to use the same
signature).

[VPlan] Don't adjust trip count for DataAndControlFlowWithoutRuntimeCheck (#183729)
Previously, the canonical IV increment may have overflowed to a non-zero
value due to vscale being a non power-of-two. So we used to emit a
runtime check for this.
If you didn't want the runtime check,
DataAndControlFlowWithoutRuntimeCheck skipped it and instead tweaked the
trip count so it wouldn't overflow.
However #144963 stopped the check from ever being emitted because vscale
is always a power-of-two on AArch64 and RISC-V, so it never overflowed
to a non-zero value. And in #183292 the code to emit the check was
removed. But we never restored the trip count back to normal when the
target's vscale was a power-of-two.
Now that vscale is always a power-of-two, this PR avoids adjusting it. A
follow up NFC can then remove DataAndControlFlowWithoutRuntimeCheck.

[CodeGen] Allow `-enable-ext-tsp-block-placement` and `-apply-ext-tsp-for-size` passed together (#183642)
Currently, the asserts fires when both `UseExtTspForPerf` and
`UseExtTspForSize` are true on a given function.
Ideally, we should allow `-enable-ext-tsp-block-placement` and
`-apply-ext-tsp-for-size` passed together, meaning run the block
placement for performance on hot functions, while run the placement for
size on cold functions.
The diff makes `UseExtTspForPerf` and `UseExtTspForSize` mutually
exclusive per-function: functions with the `OptForSize` attribute use
ext-tsp block placement for size, while the others use ext-tsp block
placement for perf.

-fexperimental-relative-c++-abi-vtables, with %pltpcrel %gotpcrel. The
syntax is not used in humand-written assembly code, and is not supported
by GNU assembler.
Also replace the recent `@funcinit` with `%funcinit(x)`.

[AMDGPU] Fix piggybacking after commute in AMDGPULowerVGPREncoding (#183778)
After successfully commuting an instruction to be compatible with the
current VGPR MSB mode, update CurrentMode with the commuted
instruction's mode requirements. This locks in the mode bits the
commuted instruction relies on, preventing later instructions from
piggybacking and corrupting those bits.
Without this fix, a subsequent instruction needing a different mode
could piggyback onto the preceding s_set_vgpr_msb and change mode bits
that the commuted instruction depends on. For example, a nullopt src1
position (treated as 0) could be overwritten to a different value,
causing incorrect register encoding for the commuted instruction.
The fix still allows compatible piggybacking - instructions that only
add new mode bits without changing existing ones can still piggyback.

Bumps the supported version to 6. Unit header layout hasn't changed

This by no means claims full DWARFv6 support, but is handy for testing
DWARFv6 features while full support is being gradually implemented.

`DenseElementsAttr::reshape()` and

Guard both fold paths with a `hasStaticShape()` check so they return
early when the result type contains a dynamic dimension.

[mlir][test-ir-visitors] Fix noSkipBlockErasure crash with block args used across blocks (#183828)
The noSkipBlockErasure callback in TestVisitors.cpp dropped uses of op
results within the same region before erasing a block, but did not drop
uses of the block's own arguments (e.g. function entry block arguments).
When the block was subsequently erased its block arguments were
destroyed while their use-lists were still non-empty, triggering the
assertion in IRObjectWithUseList::~IRObjectWithUseList().
Fix this by also iterating over the block's arguments and dropping any
uses that belong to the same parent region. This mirrors the existing
logic for op result uses and makes the block-erasure walk handle IRs
where function arguments are consumed by ops in sibling blocks.
Also replace `block->front().getParentRegion()` with
`block->getParent()` for robustness (avoids UB when the block has no
ops).
Add a regression test based on the reproducer from
https://github.com/llvm/llvm-project/issues/182996.

`AffineLinearizeIndexOp::fold` guarded the constant-folding path with
`llvm::is_contained(adaptor.getMultiIndex(), nullptr)`, which only
catches operands that have not been evaluated at all. When an operand
folds to `ub.PoisonAttr`, the attribute is non-null so the guard passed,
and the subsequent `cast<IntegerAttr>(indexAttr)` call crashed with an
assertion failure.
Fix by replacing the null-only check with one that requires every
multi-index attribute to be a concrete `IntegerAttr`, returning
`nullptr` for any other attribute (including null and PoisonAttr).

[AArch64][PAC] Emit `!dbg` locations in `*_vfpthunk_` functions (#179688)
The usage of pointers to member functions with Pointer Authentication
requires generation of `*_vfpthunk_` functions. These thunk functions
can be later inlined and optimized by replacing the indirect call
instruction with a direct one and then inlining that function call.
In absence of `!dbg` metadata attached to the original call instruction,
such inlining ultimately results in an assertion "!dbg attachment points
at wrong subprogram for function" in the assertions-enabled builds. By
manually executing `opt` with `-verify-each` option on the LLVM IR
produced by the frontend, an actual issue can be observed: "inlinable
function call in a function with debug info must have a !dbg location"
after the replacement of indirect call instruction with the direct one
takes place.
This commit fixes the issue by attaching artificial `!dbg` locations to
the original call instruction (as well as most other instructions in
`*_vfpthunk_` function) the same way it is done for other
compiler-generated helper functions.

[mlir][IR] Generalize `DenseElementsAttr` to custom element types (#183891)
`DenseElementsAttr` supports only a hard-coded list of element types:
`int`, `index`, `float`, `complex`. This commit generalizes the
`DenseElementsAttr` infrastructure: it now supports arbitrary element
types, as long as they implement the new `DenseElementTypeInterface`.
The `DenseElementTypeInterface` has the following helper functions:
- `getDenseElementBitSize`: Query the size of an element in bits. (When
storing an element in memory, each element is padded to a full byte.
This is an existing limitation of the `DenseElementsAttr`; with an
exception for `i1`.)
- `convertToAttribute`: Attribute factory / deserializer. Converts bytes
into an MLIR attribute. The attribute provides the assembly format /
printer for a single element.
- `convertFromAttribute`: Serializer. Converts an MLIR attribute into
bytes.
Note: `convertToAttribute` / `convertFromAttribute` are mainly for
writing test cases. For performance reasons, `DenseElementsAttr` users
should work with raw bytes / elements and avoid any API that
materializes MLIR attributes. However, MLIR attributes typically have
human-readable parsers/printers, making them suitable for lit tests and
debugging.
This PR introduces an additional assembly format for
`DenseElementsAttrs`. There are now two formats. (The existing one is
kept for compatibility reasons.)
- Literal-first (existing): `dense<[1, 2, 3]> : tensor<3xi32>`
- Type-first (new): `dense<tensor<3xi32> : [1 : i32, 2 : i32, 3 : i32]>`
The new syntax is needed to disambiguate between "literal" (e.g., `1`)
and attribute (e.g., `1 : i32`) when parsing the first token. In the
literal-first syntax, we only parse literals. In the type-first syntax,
we only parse attributes.
The existing `int`, `index`, `float`, `complex` types also implement the
`DenseElementTypeInterface`. This allows us to implement
`DenseElementsAttr::get` and `AttributeElementIterator::operator*` in a
generic way.

[mlir][VectorToLLVM] Fix crash in VectorInsertOpConversion with dynamic index (#183783)
VectorInsertOpConversion crashes with an assertion failure when
inserting a sub-vector at a dynamic position into a multi-dimensional
vector. The pattern calls getAsIntegers() on the position, which asserts
that all fold results are compile-time constant attributes.
The existing guard (checking llvm::IsaPred<Attribute>) only covered the
case where a scalar is inserted into the innermost dimension (the
extractvalue path). The guard was missing for the insertvalue path when
inserting a sub-vector at a dynamic position into a nested aggregate.
Fix: add the same guard before the llvm.insertvalue creation to return
failure() gracefully when any position index is dynamic, matching the
behavior of VectorExtractOpConversion.
Fixes #177829

yet due to pcb structure issue, but this change still achieves feature
parity with KGDB. Trapframe unwinding support will be implemented in
future. Test files using core dump from ppc64le will be implemented once
other kernel debugging improvements are done.

[mlir][GPU] Fix crash in WarpExecuteOnLane0Op::verify with wrong terminator (#183930)
WarpExecuteOnLane0Op::verify() called getTerminator() which performed an
unconditional cast<gpu::YieldOp> on the block's last operation. When the
op body was written with a different terminator (e.g. affine.yield), the
cast asserted immediately instead of emitting a verifier diagnostic.
Fix by using dyn_cast in verify() before calling getTerminator(), and
emitting a proper error message when the terminator is not gpu.yield.
Add a regression test to invalid.mlir.

Due to special handling of Whitesmiths when parsing, the additional

were not being applied. Consequently, when calculating the access
modifier indent offset, the modifiers were being placed at the class
level.
This change ensures that the additional level(s) are not omitted for
Whitesmiths.

Requesting the last entry in the ZIP file often fails because of a bug
in the entry search mechanism. This PR fixes this.

[ThinLTO] Reduce the number of renaming due to promotions (#183793)
Currently for thin-lto, the imported static global values (functions,
variables, etc) will be promoted/renamed from e.g., foo() to
foo.llvm.(). Such a renaming caused difficulties in live patching
since function name is changed ([1]).
It is possible that some global value names have to be promoted to avoid
name collision and linker failure. But in practice, majority of name
promotions can be avoided.
In [2], the suggestion is that thin-lto pre-link decides whether
a particular global value needs name promotion or not. If yes, later on
in thinBackend() the name will be promoted.
I compiled a particular linux kernel version (latest bpf-next tree)
and found 1216 global values with suffix .llvm.. With this patch,
the number of promoted functions is 2, 98% reduction from the
original kernel build.
If some native objects are not participating with LTO, name promotions
have to be done to avoid potential linker issues. So the current
implementation cannot be on by default. But in certain cases, e.g., linux kernel
build, people can enable lld flag --lto-whole-program-visibility to reduce the
number of functions like foo.llvm.().
For ThinLTOCodeGenerator.cpp which is used by llvm-lto tool and a
few other rare cases, reducing the number of renaming due to promotion,
is not implemented as lld flag '-lto-whole-program-visibility' is not
supported in ThinLTOCodeGenerator.cpp for now. In summary, this pull
request only supports llvm-lto2 style workflow.
The feature is off by default. To enable the future, lld flag
'-lto-whole-program-visibility' and llvm flag
'-always-rename-promoted-locals=false' are needed.
The link [3] has more context for the pull request discussions.

[lldb] Add BytecodeSection class to formatter_bytecode.py (#183876)
Changes `formatter_bytecode.compile_file` to return a `BytecodeSection`
value. The `BytecodeSection` holds the data that needs to be emitted to
an `__lldbformatters` section.
The `BytecodeSection` currently provides `write_binary`, but will be
updated in a follow up commit to include `write_source` which will allow
the data to be emitted as C source code, or Swift source code. This will
make it easier to integrate into build systems, as it's easier to get
data into a binary via source code, than as a raw binary file.

[AMDGPU] Stop treating AMDGPU_CS_ChainPreserve as a module entry funtion (#183718)
Starting with AMD PAL metadata v3.6, pipeline ELFs cannot have a
`.shader_functions` section. However, dynamic VGPR retry helpers use
the `AMDGPU_CS_ChainPreserve` calling convention, which LLVM previously
treated as a module entrypoint, incorrectly emitting this metadata.

This PR adds the `convert_region_types` API to
`ConversionPatternRewriter` and introduces a new integration test,
`bf.py`, which demonstrates how to combine a Python-defined dialect, the
dialect conversion API, the pass manager, and the execution engine to
build a pure-Python JIT compilation pipeline.

[Clang][TableGen] Sort undocumented builtins after documented ones in generated docs (#183938)
The builtin documentation emitter previously sorted all categories

categories like "WMMA" in the generated RST. This made the output
confusing since stub entries appeared before real documentation.
Push the "Undocumented" category to the end of the output so that all
documented categories appear first, regardless of their names.

You can pass the stdlib argument either as -stdlib and --stdlib - the
previous regex did not account for this however - which caused the build
to fail, as a --stdlib argument would be replaced with a single dash,
causing clang to assume reading from stdin and the build to fail:
clang++: error: -E or -x required when input is from standard input
clang++: error: cannot specify -o when generating multiple output files

[AArch64][test] Add i256 codegen baseline tests (#183587)
## Summary
Add baseline codegen tests for i256 operations on AArch64:
- `bitcnt-i256.ll`: ctpop, ctlz, cttz, Hamming distance, parity (3 RUN
lines: +neon, +sve, +cssc)
- `cmp-i256.ll`: 8 icmp variants (slt/sgt/sle/sge/ult/ugt/ule/uge) +
select
- `div-i256.ll`: udiv, sdiv, urem, srem, power-of-2, and constant
division
- `mul-i256.ll`: multiply, multiply-by-constant, add, sub, and, or, xor
- `shift-i256.ll`: variable shl/lshr/ashr, constant shifts, narrow (i32)
amounts
These are test-only NFC pre-patches for `__int256` builtin type support
(#182733). i256 is already a valid LLVM IR type; these tests capture the
current baseline codegen. The main PR will update the CHECK lines to
show codegen improvements (e.g., direct libcall routing for
division/multiply).
## Test plan
- All 5 tests pass with `llvm-lit` on upstream `main` (generated with
`update_llc_test_checks.py` using upstream `llc`)

[mlir][IR] Generalize `DenseElementsAttr` to custom element types (#183920)
`DenseElementsAttr` supports only a hard-coded list of element types:
`int`, `index`, `float`, `complex`. This commit generalizes the
`DenseElementsAttr` infrastructure: it now supports arbitrary element
types, as long as they implement the new `DenseElementTypeInterface`.
The `DenseElementTypeInterface` has the following helper functions:
- `getDenseElementBitSize`: Query the size of an element in bits. (When
storing an element in memory, each element is padded to a full byte.
This is an existing limitation of the `DenseElementsAttr`; with an
exception for `i1`.)
- `convertToAttribute`: Attribute factory / deserializer. Converts bytes
into an MLIR attribute. The attribute provides the assembly format /
printer for a single element.
- `convertFromAttribute`: Serializer. Converts an MLIR attribute into
bytes.
Note: `convertToAttribute` / `convertFromAttribute` are mainly for
writing test cases. For performance reasons, `DenseElementsAttr` users
should work with raw bytes / elements and avoid any API that
materializes MLIR attributes. However, MLIR attributes typically have
human-readable parsers/printers, making them suitable for lit tests and
debugging.
This PR introduces an additional assembly format for
`DenseElementsAttrs`. There are now two formats. (The existing one is
kept for compatibility reasons.)
- Literal-first (existing): `dense<[1, 2, 3]> : tensor<3xi32>`
- Type-first (new): `dense<tensor<3xi32> : [1 : i32, 2 : i32, 3 : i32]>`
The new syntax is needed to disambiguate between "literal" (e.g., `1`)
and attribute (e.g., `1 : i32`) when parsing the first token. In the
literal-first syntax, we only parse literals. In the type-first syntax,
we only parse attributes.
The existing `int`, `index`, `float`, `complex` types also implement the
`DenseElementTypeInterface`. This allows us to implement
`DenseElementsAttr::get` and `AttributeElementIterator::operator*` in a
generic way.

[MLIR][SymbolTable] Fix crash when SymbolTable is built on unverified IR (#183945)
The SymbolTable::SymbolTable constructor asserted that all symbol names
in the region were unique. This could cause mlir-opt to crash instead of
producing a proper diagnostic when the IR contained both:
1. An IsolatedFromAbove op (e.g., irdl.dialect) with a symbol user that
looks up symbols in an ancestor symbol table, and
2. Duplicate symbols in that ancestor (e.g., two func.func @test).
The crash occurred because IsolatedFromAbove ops are verified in
verifyOnExit() before verifyRegionInvariants() runs the SymbolTable
trait's verifyRegionTrait (which produces the proper duplicate-symbol
diagnostic). When the isolated op's symbol use verification triggered
SymbolTableCollection::getSymbolTable() on the ancestor, the constructor
would assert instead of gracefully handling the invalid-but-not-yet-
reported duplicate symbols.
The fix removes the assertion and silently skips duplicate symbol
insertions (keeping the first definition). The proper diagnostic is
still produced by the SymbolTable trait's verifyRegionTrait, which runs
after all children have been verified.
Add a regression test in invalid.irdl.mlir using a self-referencing IRDL
parametric type combined with duplicate function symbols.

[mlir][scf] Fix crash in ForOp verifier when body block has no arguments (#183946)
A malformed `scf.for` whose body block contains no arguments caused
`getRegionIterArgs()` to crash via an out-of-bounds `drop_front(1)`
call. This happened because `verifyLoopLikeOpInterface` (a
`verifyRegionTrait`) invokes `getRegionIterArgs()` during
`verifyRegionInvariants`, which runs before `verifyRegions()` has a
chance to report a proper diagnostic.
Fix by adding an explicit check in `ForOp::verify()` (which runs in
`verifyInvariants`, before any region trait verifiers execute) that
ensures the body block has at least as many arguments as there are
induction variables. This prevents the crash and produces a clear error
message.

[MLIR][ODS] Fix AllElementCountsMatch crash on dynamic shaped types (#183948)
The AllElementCountsMatch trait called ShapedType::getNumElements() on
operands or results with dynamic dimensions, which unconditionally
asserts hasStaticShape(). This caused mlir-opt to crash instead of
failing gracefully when the trait was used with dynamically-shaped
types.
Fix this by rewriting AllElementCountsMatch to use an And<> predicate
combining Neg<AnyMatchOperatorPred> (requiring all types to be
statically shaped) with AllMatchSameOperatorPred (requiring equal
element counts). When any type has dynamic dimensions the verification
now fails with a diagnostic instead of crashing.
Update the regression test to expect a verification failure rather than
success when dynamic shapes are present.

[mlir][python] Add stable ABI (abi3) support (#183856)
Add `MLIR_ENABLE_PYTHON_STABLE_ABI` cmake flag to build bindings against
the Python limited/stable API (abi3 / PEP 384). This allow for
compatibility across different >=3.12 versions with a single .so /
wheel. We also require CMake >=3.26.
The stable ABI restricts usage to a subset of the CPython C API: frame
and code object structs are opaque, so introspection APIs like
`PyCode_Addr2Location`, `PyFrame_GetLasti`, and `PyFrame_GetCode` are
unavailable. The traceback-based auto-location logic is dropped because
we don’t have stable ABI to produce complete locations.

proofs from the previous changes generally apply here as well because we
effectively match on reductions of size M x N.

[VPlan] Support arbitrary predicated early exits. (#182396)
This removes the restriction requiring a single predicated early exit.
Using MaskedCond, we only combine early-exit conditions with block
masks from non-exiting control flow.
This means we have to ensure that we check the early exit conditions in
program order, to make sure we take the first exit in program order that
exits at the first lane for the combined exit condition.
To do so, sort the exits by their reverse post-order numbers.

This is mostly just cleanup, but it will also help with future changes
to the diagnostic system by letting us focus on the custom diagnostic
scenarios that _don't_ fit into the usual pre-declared diagnostic
scenario.

leading to an incorrect codegen for other uses

[AMDGPU] Make uniform-work-group-size a valueless attribute (#183925)
The "uniform-work-group-size" function attribute previously took a
string value of "true" or "false". Since presence alone can convey the
"true" semantics and absence can convey "false", the value is
unnecessary.
This patch converts it to a valueless string attribute: presence
indicates true, absence indicates false. For backward compatibility,
auto-upgrade logic is added in both UpgradeAttributes (bitcode) and
UpgradeFunctionAttributes: if the old value is "true", the attribute is
kept without a value; if "false", the attribute is removed.

[clang][Sema] fix crash on __type_pack_element with dependent packs (GH180307) (#180407)
dependent pack expansions in __type_pack_element can result in
single-element template argument lists. When performing semantic
analysis for these builtins, the compiler needs to account for the
dependent expansions and handle them without triggering strict size
assertions. The patch adds this analysis and ensures we either defer
evaluation for dependent cases or report clear out-of-bounds diagnostics
instead of crashing

[MLIR][Python] Support attribute definitions in Python-defined dialects (#183907)
This PR is quite similiar to
https://github.com/llvm/llvm-project/pull/182805.
We added basic support of attribute definitions in Python-defined
dialects, including:
- IRDL codegen for attribute definitions
- Attr builders like `MyAttr.get(..)` and attr parameter accessors (e.g.
`my_attr.param1`)
- Use Python-defined attrs in Python-defined operations

ValueTracking/AMDGPU: handle mbcnt in computeKnownBitsFromOperator (#183229)
This helps canonicalize some address calculation. This would further
help immediate folding into memory load instructions in the backend.
The order changes to v_mad_u32_u24 is just because
@llvm.amdgcn.mul.u24.i32 was used in codegen prepare after this change.
It does not really change anything important.

happen otherwise. It does not try to suggest ``std::move`` when they are
valid but obviously not profitable (e.g. for trivially movable types)

dump. Between static counter reset and increment, we use atomic store
in counter reset - the counter increment sequence inserted within user
code already takes care of thread safety, so we just need to make sure
the counter reset code is also thread safe (no torn write to counter).

[BOLT] Make sure IOAddressMap exist before lookup (NFC) (#183184)
`BinaryFunction::translateInputToOutputAddress()` contains fallback
logic in case that querying `IOAddressMap` doesn't yield an output
address. Because this function could be called in scenarios where
`IOAddressMap` won't be set up, we should check if the map actually
exists before lookup.

[RISCV] Relax codegen predicates for HINT-based instructions (#179872)
Following the assembler/disassembler changes in #178609, this patch also
relaxes the codegen predicates for HINT-based instructions. Since these
instructions use encodings that are architecturally guaranteed not to
trap, the compiler can safely generate them regardless of extension
availability.
Changes:
- int_riscv_pause: Remove HasStdExtZihintpause predicate. The pause
intrinsic now generates the FENCE hint encoding unconditionally.
- NTL hints: Remove hasStdExtZihintntl() check in emitNTLHint().
Non-temporal locality hints are now emitted for all nontemporal memory
operations.

[compiler-rt][ARM] Fix conditions for strict-mode FP testing (#183507)
On sufficiently old versions of the Arm architecture, the optimized FP
routines are not enabled. So commit a84ee1416b6c179 should not have
enabled the extra-strict tests that go with them.
Also in that commit, I wrote a comment saying I was setting two separate
compile-time definitions (-DCOMPILER_RT_ARM_OPTIMIZED_FP and
-DCOMPILER_RT_ARM_OPTIMIZED_FP_THUMB1), and then didn't actually do it!
This caused the strict mulsf3 tests to be wrongly disabled in Thumb2.

Fixes https://github.com/llvm/llvm-project/issues/181271
If a variable is marked firstprivate in a nested task but not actually
used in the outer task body, we still need the outer task to capture it
as firstprivate. Otherwise the nested task can end up pointing to the
parallel region’s stack frame, which might already be gone when the
deferred task runs, causing a use-after-free.

[LangRef] Clarify nsz semantics (#180906)
The current LangRef wording says that the sign of a zero argument or
result is "insignificant", which is not really clear on what this means.
Alive2 models this as non-deterministically flipping the zero sign bits
for both inputs and outputs.
This PR proposes to specify this flag as non-deterministically flipping
inputs only. A consequence of this is that fabs is guaranteed to have an
unset sign bit even if the input is zero (that is,
https://alive2.llvm.org/ce/z/irCftQ is no longer a valid transform), and
that the copysign result sign only depends on the second operand (that
is, https://alive2.llvm.org/ce/z/VnHdfh is no longer a valid transform).
These rules are still more liberal than we'd really like them to be, but
at least avoid some of the issues with nsz.
This is based on the discussion in:

[lldb] Indent option help with ANSI cursor codes when possible. (#183558)
This avoids formatting empty space when a range of text formatted by
ANSI codes is split across lines.
This is not currently done in any option, but the `${...}` syntax we
have does support marking any range of text, so it could be done in
future, and fixing it is simple.
As an example, if I change a breakpoint option:
```
"${S}et the breakpoint only in this shared library. Can repeat "
- "this option multiple times to specify multiple shared libraries.">;
+ "this option multiple ${times to specify multiple} shared libraries.">;
```
This applies the underline to words that will be split across lines. In
the outputs below, `^` represents an underlined character.
With spaces:
```
-s <shlib-name> ( --shlib <shlib-name> )
Set the breakpoint only in this shared library. Can repeat this option multiple times to
^^^^^^^^
specify multiple shared libraries.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
```
The indent and the text are underlined, this is not what we want.
With cursor movement:
```
-s <shlib-name> ( --shlib <shlib-name> )
Set the breakpoint only in this shared library. Can repeat this option multiple times to
^^^^^^^^
specify multiple shared libraries.
^^^^^^^^^^^^^^^^
```
Only the text is underlined, which is correct.
If we are not allowed to use ANSI (use-color is off), then the
descriptions will be stripped of ANSI anyway, so this is not a problem.

[AArch64][GlobalISel] Use GPR for illegal fconstants and extend < 32 bit GPR constants to 32 bits (#178692)
In a similar fashion to
https://github.com/llvm/llvm-project/pull/175810, this PR aims to
simplify the handling of constants by extending smaller than 32 bit
integer constants to 32 bits in regbankselect. This is only done for
constants that were going to be assigned to a GPR and aims to simplify
the selection of these.
In addition, fconstants that would have lead to a constant pool load
because they are illegal as immediates (except for 128 bit) are now
converted to a constant on GPR registers before being copied to the FPR.
This hopefully reduces cache pressure & simplifies selection.
I have tried to rely on tablegen as much as possible for selecting the
instructions for this.

[AArch64] Vectorise llvm.pow using vector intrinsic for ArmPL library (#183319)
When vectorising loops containing calls to the llvm.pow intrinsic we
currently end up with direct calls to the vector math library equivalent
of llvm.pow. This causes problems later on because we then miss out on
optimisations in the backend for things like
pow(x, 0.25)
pow(x, 0.75)
etc.
There are a few different ways of trying to solve this, but I think the
cleanest way is to leave the call in the intrinsic form and then teach
the backend how to lower the FPOW DAG node to the vector math library
function. This is similar to what we already do for llvm.sincos/FSINCOS
today.
I've done this by removing the entries in Analysis/VecFuncs.def that map
the intrinsic to the vector math functions, whilst also teaching the

[lldb] Fix wchar addition tests in DIL (#184082)
This patch fixes tests on systems where `wchar`'s underlying type is
`unsigned long`, or `long` and `int` types have the same width, so
`unsigned int` gets promoted to `unsigned long` during binary addition.
These tests check that `wchar` types get promoted to regular integer
types at all.

[mlir][x86] Move AMX dialect into X86 dialect (#183717)
Unifies the two dialects that define x86 operations into a single one.
The AMX dialect is moved into X86 in line with other x86 extensions.
Following the dialect renaming, X86 dialect is now a suitable home for
wider range of operations targeting specific hardware features. Moving
AMX definitions to X86 dialect creates a single, centralized hub for
defining all x86 intrinsic-like operations. The new grouping aims to
eliminate the need for new dialects as new hardware extensions become
available.
The two dialects are simply merged together. X86 dialect refactoring
will be addressed separately.
List of changes:
- operations: 'amx.tile_*' => 'x86.amx.tile_*'
- types: '!amx.tile' => '!x86.amx.tile'
- namespace: 'mlir::amx' => 'mlir::x86::amx'
- test define: 'MLIR_RUN_AMX_TESTS' => 'MLIR_RUN_X86_AMX_TESTS'
- vector lowering: AMX is enabled by default together with X86
The MLIR AMX tests are now nested under X86 directory. To enable AMX
integration tests, 'MLIR_RUN_X86_TESTS' must also be defined.

[DAG] visitCLMUL - fold (clmul x, c_pow2) -> (shl x, log2(c_pow2)) (#184049)
Implements the missing basic folds for `ISD::CLMUL` in `visitCLMUL`:
- `(clmul x, 1)` → `x`
- `(clmul x, c_pow2)` → `(shl x, log2(c_pow2))`
These were previously only folded during scalar expansion
(`expandCLMUL`), so targets with native CLMUL support (e.g. X86 pclmul,
RISCV Zbc) never had the opportunity to simplify these cases.

[mlir][emitc] Fix crash in form-expressions when identity cast is folded (#183894)
When the --form-expressions pass runs applyPatternsGreedily, the greedy
rewriter calls CastOpInterface::foldTrait on ops inside ExpressionOp
bodies. For an identity cast (e.g. `emitc.cast i32 to i32`), this fold
succeeds and replaces the op's result with its operand (a block
argument), leaving the ExpressionOp body in the form `{ yield %arg }`.
Subsequently, if the cast expression's result had its use count reduced
to one (e.g. because a dead non-EmitC use was eliminated),
FoldExpressionOp would select this expression as a candidate to fold
into an outer expression. It then calls usedExpression.getRootOp(),
which returns nullptr because the body yields a block argument rather
than an op result. The subsequent mapper.lookup(nullptr) crashes with an
assertion.
Fix by adding a FoldTrivialExpressionOp canonicalization pattern that
handles ExpressionOps whose body yields a block argument directly: such
an expression is a passthrough and can be replaced by the corresponding
operand value. This canonicalization fires during greedy rewriting
before FoldExpressionOp encounters the invalid state.
Fixes #179844

[flang][OpenMP] Fix counting generated nests (#183957)
The code in `CountGeneratedNests` returned std::nullopt if the LOOPRANGE
clause was not present on a FUSE construct. That is incorrect, the
answer should be 1 instead, except in cases where the FUSE itself was
invalid, such as having no loops nested in it.
Returning std::nullopt will not cause any messages to be emitted. The
case of zero loops inside of FUSE will be diagnosed when analyzing the
body of the FUSE construct itself, not when checking a construct in
which the FUSE is nested.
This prevents error messages caused by the same problem from being
emitted for every enclosing loop construct.

[openmp][cmake][NFCI] Avoid non-eval uses of ${var} (#182267)
When using
set(var "Example")
if (${var})
CMake will first resolve the if-argument to
if (Example)
And what then happens depends on the existance of a variable with the
name "Example":
1. If instead of "Example", a truth constant is used ("TRUE", "FALSE",
"ON", "OFF", "", "-NOTFOUND" ...), it is prioritized
(https://cmake.org/cmake/help/latest/command/if.html#constant)
2. If a variable with the name "Example" exists: Use the truthiness of
its content
(https://cmake.org/cmake/help/latest/command/if.html#variable)
3. Otherwise, it is false-y
That is, the the result of the conditional does not only depend on the
content of `var`, but also some other variable. This is usually
unintended and leads to problems such as addressed with #154537. The
only case where this is intended is when passing an expression to be
evaluated such as with `pythonize_bool`, `append_if` and
`libomp_append`. In all other cases, using `${var}` without quotes is a
pattern to be avoided.
Remark:
If `${var}` is not one of the values considered a [truthiness
constant](https://cmake.org/cmake/help/latest/command/if.html#constant),
the result of `if (var)` and `if ("${var}")` is different:
* `if (var)` is true-ish
(https://cmake.org/cmake/help/latest/command/if.html#variable)
* `if ("Example")` and therefore `if ("${var}")` are false-y
(https://cmake.org/cmake/help/latest/command/if.html#string)
In this PR I am preferring `if (var)` over `if ("${var}")` because has
less clutter, resembles Python's behaviour, and problably what most
users are expecting, even though `if (${var})` in most cases would
evaluate to false-y because a variable does not exist. This ambiguity
does not exist for STREQUAL and MATCHES.

[CMake] Add LLVM_ENABLE_WARNING_SUPPRESSIONS to toggle warning suppressions (#183439)
This PR introduces a new opt-in CMake option
`LLVM_ENABLE_WARNING_SUPPRESSIONS` (default `ON`) to toggle warning
suppressions
Previously, several compiler warnings were explicitly disabled using
`-wd` (for MSVC) or `-Wno-...` (for GCC/Clang) flags by default.
However, this causes validation failures with strict compliance scanners
like BinSkim, which require builds to run without any warning
suppressions to meet SDL compliance standards.
This change introduces an opt-in `LLVM_ENABLE_WARNING_SUPPRESSIONS`
option (default ON). When explicitly disabled (OFF), it selectively
filters out the `-wd` flags for MSVC and removes all `-Wno-...` flags
for GCC/Clang in HandleLLVMOptions.cmake. This ensures all compiler
warnings are exposed as intended for static analysis tools while
preserving the default noise-free build experience for regular users.
The option has also been exported to `LLVMConfig.cmake.in` and
documented in `CMake.rst`.

This commit ensures that the validation pass checks for the presence of
inferable dimensions (represented by -1) in reshape and slice
operations. These are not compliant with the TOSA specification. If such
dimensions are found, an error message is emitted indicating that they
do not conform to the TOSA specification.

[mlir][tosa] Fix crash in TosaInferShapes when while_loop carries sparse tensors (#183943)
TypeModificationState::commit() inserted a tensor.cast immediately after
the defining operation of the value whose type changed. For block
arguments (e.g., loop-carried variables in tosa.while_loop), there is no
defining operation, so getDefiningOp() returns nullptr, causing a
segmentation fault when the insertion point was set via
setInsertionPointAfter(nullptr).
Fix by checking whether the value is defined by an operation; if not
(i.e., it is a block argument), insert the cast at the start of the
block that owns the argument.
Fixes #181449

[libc] Fix GPU loader propagation to lit test infrastructure (#184105)
The lit-based test execution added in c776a52fa263 did not propagate the
GPU loader executable to the lit site configuration. When building for
GPU targets, the loader (amdhsa-loader, nvptx-loader, or a
user-specified LIBC_GPU_LOADER_EXECUTABLE) was resolved into the
libc.utils.gpu.loader target but never passed through to the generated
lit.site.cfg.py.
Fix this by resolving the executable path from the libc.utils.gpu.loader
target property and including it in configure_lit_site_cfg's PATHS list.
In lit.site.cfg.py.in, if no explicit LIBC_TEST_CMD is set but a GPU
loader is present, construct libc_test_cmd from the loader path,
mirroring the logic in add_libc_hermetic() in LLVMLibCTestRules.cmake.
Tested:
* GPU build with LIBC_GPU_LOADER_EXECUTABLE set to /bin/echo used to
fail (tried to run the binary), now it works.
* Native compiler check-libc-lit continues to work after this change.

[flang] Inline trivial scalar allocatable assignments in HLFIR-to-FIR (#183177)
For trivial scalar allocatable assignments (non-polymorphic,
non-character, non-array, non-temporary), inline the assignment directly
instead of calling the `_FortranAAssign` runtime. The inlined code
checks whether the allocatable is already allocated: if so, it stores
directly; otherwise, it allocates memory via `fir.allocmem`, stores, and
updates the box descriptor. The if-branch is necessary to handle both
cases:
```fortran
integer, allocatable :: k
allocate(k)
k = 42 ! already allocated: store directly
```
```fortran
integer, allocatable :: k
k = 42 ! not allocated: allocmem, store, update box
```

[LinkerWrapper] Fix a bunch of minor issues and typos (#183679)
Summary:
A bunch of small issues found through linting and LLM checking.
- Broken sort comparator that violated strict weak ordering (UB)
- SearchLibrary corrupting .lib filenames via erroneous drop_front()
- Hardcoded x86_64-unknown-linux-gnu host triple in AMDGPU fatbinary
- OffloadFile loop variable shadowing its own type, causing std::move on
the type rather than the variable
- GetDeviceInput calling exit() directly instead of returning Error
- Redundant double-wrapping of DerivedArgList
- Various typo and style fixes

[mlir][bazel] Fix build after moving AMX into X86 in #183717. (#184165)
This PR fixes the bazel build that got broken by #183717, which moved
the AMX dialect into the X86 dialect. The fix consists of replicating
the changes from the CMake files into BUILD files as usual; in this
case, mostly removing the AMX dialect targets, adding a few new
references to the corresponding X86 targets, and adding a few new
dependencies to the existing X86 targets due to the new code.

[clang][ssaf] Add `JSONFormat` serialization support for `LUSummary` and `LUSummaryEncoding`
This change extends `SerializationFormat` and `JSONFormat` with APIs to
read and write `LUSummary` and `LUSummaryEncoding`, completing the
serialization interface for both TU-level and LU-level summaries. As
part of the implementation, common serialization infrastructure has been
extracted into `JSONFormatImpl.{cpp, h}`, eliminating duplication across
the TU and LU translation units. A comprehensive `LUSummaryTest` suite
has been added to test `LUSummary` and `LUSummaryEncoding`, mirroring
the structure of the existing `TUSummaryTest` suite. Shared testing
infrastructure has been extracted into `JSONFormatTest.{cpp, h}`.

[flang][OpenMP] Support custom mappers in target update to/from clauses (#169673)
Implement support for the OpenMP `mapper` modifier on `target update` `to` and
`from` clauses in Flang.
Semantic name resolution is extended to bind the mapper symbol for
`OmpClause::To` and `OmpClause::From` via a shared `ResolveMapperModifier`
helper. Lowering is extended in `ClauseProcessor` with a `getMapperIdentifier`
template helper to extract the mapper name for both `map` and `target update`
clauses and forward it to `omp.map_info`.
Fixes #168701.

[APINotes] Refactor APINotesReader to propagate llvm::Error (#183812)
**Context:** While exploring the `APINotes` codebase, I found 54 `FIXME`
comments in `APINotesReader.cpp` stating: `// FIXME this drops the error
on the floor.`
This happened because the internal `read*Block` methods returned a
boolean, and the `APINotesReader` constructor reported failures via a
`bool &Failed` out-parameter. This forced the actual `llvm::Errors`
returned from the bitstream cursor to be silently consumed with
`consumeError()`.
This patch refactors this behavior to properly propagate the errors up
the stack.
**Changes in this patch:**
**1.** Changed all `read*Block` methods in
`APINotesReader::Implementation` to return `llvm::Error` instead of
`bool`.
**2.** Made the `APINotesReader` and `Implementation` constructors
private.
**3.** Created a static factory method `APINotesReader::Create(...)`
that returns an `llvm::Expected<std::unique_ptr<APINotesReader>>`,
allowing us to propagate the error instead of dropping it.
**4.** Updated `APINotesManager.cpp` to handle the new `Expected` return
type. (Note: For now, `APINotesManager` consumes the error to maintain
its existing behavior, but the `APINotesReader` is now fully ready for
future error propagation).

[clang][Modules] Handle relocated modules during implicit module builds (#181836)
* To avoid the build time overhead of checking for relocated modules,
only check it once per build session.
* Enable relocated module checks in the dependency scanner.
* Add remarks to know when this is happening with `-Rmodule-validation`
This check is necessary to be able to handle new libraries appearing in
earlier search paths. This is a valid scenario when dependency info
changes between incremental builds of the same scheme, thus new build
sessions.
It is still malformed to expect new versions of libraries to be added
within the same build session.

When a memory-reading or memory-writing instruction is not a

back to the loop header location instead of pointing at the actual
problematic instruction.
Pass &I (the actual Instruction) instead.

[lldb][Target] Allow eLanguageTypeAssembly to use ScratchTypeSystemClang (#183771)
After cleaning up some of our `LanguageType`/`SourceLangage`
round-tripping (see `7f51a2a47d2e706d04855b0e41690ebafa2b3238`), a CU
with `DW_LANG_MIPS_Assembler` will get a language type of
`eLanguageTypeAssembly` (as opposed to `eLanguageTypeMipsAssembler`).
Reason being that there is no `DW_LNAME_` (DWARFv6 language code) for
`MIPS Assembler`, only for generic `Assembly`. So it's not possible to
round-trip cleanly between pre-DWARFv6 and DWARFv6 language codes, which
LLDB relies on for storing language types (and will lean into more
heavily in the future). This broke a special provision we have where we
allow `ScratchTypeSystemClang` to be used when evaluating expressions in
assembly CUs (i.e., CUs where the debug-info explicitly sets the
language to assembly).
If we ever want to distinguish MIPS from other Assembly, the proper way
to do so is introduce a `DW_LNAME_Mips_Assembler`. For now, this patch
adds another case for `eLanguageTypeAssembly` in
`GetScratchTypeSystemForLanguage`.
The test is a bit quirky because it checks for error messages in all
cases. For the `TypeSystem`s to exist we would have to initialize the
`TypeSystem` plugins, which I couldn't find a precedent for. But happy
to hear other suggestions for testing

[NVPTX] Refactor NVPTXLowerArgs and move helpers to NVPTXUtilities (#183686)
A couple of refactoring changes to simplify `NVPTXLowerArgs` and reduce
unnecessary coupling to `NVPTXTargetLowering`:
- Move `getFunctionParamOptimizedAlign`, `getFunctionArgumentAlignment`,
and `getFunctionByValParamAlign` from `NVPTXTargetLowering` to
`NVPTXUtilities` as free functions. These don't use any TLI state and
were only member functions because they called each other. This also
lets `getArgumentAlignment` become file-static in
`NVPTXISelLowering.cpp`, and removes the `NVPTXTargetLowering`
dependency from `NVPTXLowerArgs` for byval alignment.
- Split the CUDA kernel pointer-marking logic out of `NVPTXLowerArgs`
into a new `NVPTXMarkKernelPtrsGlobal` pass. This code (marking pointers
loaded from byval params as global, handling int-to-ptr patterns) is
conceptually independent of the argument lowering and was guarded by a
`DrvInterface == CUDA` check that is now at pipeline scheduling time.
The new pass is a simple `FunctionPass` with no `TargetMachine`
dependency.

[lldb] Batch breakpoint step-over for threads stopped at the same BP (#183412)
When multiple threads are stopped at the same breakpoint, LLDB currently
steps each thread over the breakpoint one at a time. Each step requires
disabling the breakpoint, single-stepping one thread, and re-enabling
it, resulting in N disable/enable cycles and N individual vCont packets
for N threads. This is a common scenario for hot breakpoints in
multithreaded programs and scales poorly.
This patch batches the step-over so that all threads at the same
breakpoint site are stepped together in a single vCont packet, with the
breakpoint disabled once at the start and re-enabled once after the last
thread finishes.
At the top of WillResume, any leftover StepOverBreakpoint plans from a
previous cycle are popped with their re-enable side effect suppressed
via SetReenabledBreakpointSite, giving a clean slate.
SetupToStepOverBreakpointIfNeeded then creates fresh plans for all
threads that still need to step over a breakpoint, and these are grouped
by breakpoint address.
For groups with multiple threads, each plan is set to defer its
re-enable through SetDeferReenableBreakpointSite. Instead of re-enabling
the breakpoint directly when a plan completes, it calls
ThreadFinishedSteppingOverBreakpoint, which decrements a per-address
tracking count. The breakpoint is only re-enabled when the count reaches
zero.
All threads in the largest group are resumed together in a single
batched vCont packet. If some threads don't complete their step in one
cycle, the pop-and-recreate logic naturally re-batches the remaining
threads on the next WillResume call.
For 10 threads at the same breakpoint, this reduces the operation from
10 z0/Z0 pairs and 10 vCont packets to 1 z0 + 1 Z0 and a few
progressively smaller batched vCont packets.
EDIT:
Tried to merge this PR twice, the first time the test was flaky so we
had to revert. The second time, we broke 2 tests on windows machine:
https://lab.llvm.org/buildbot/#/builders/141/builds/15798
The tests that were failing were failing because the cleanup code in
`WillResume` was popping **ALL** `StepOverBreakpoint` plans, including
non-deferred ones from incomplete single-steps.
The issue was:
1) Multiple threads hit the same breakpoint. One thread's breakpoint
condition evaluates to false, so it needs to auto-continue.
2) A `StepOverBreakpoint` plan is created for that thread
(non-deferred).
3) On the next WillResume, the cleanup pops that non-deferred plan.
4) Now the `StopOthers` scan finds no thread with a StopOthers() plan,
so thread_to_run stays null.
5) The else branch runs, calling `SetupToStepOverBreakpointIfNeeded` on
**ALL** threads, including the thread that legitimately hit the
breakpoint with a true condition.
6) That thread gets a new `StepOverBreakpoint` plan pushed, which
overwrites its breakpoint stop reason with trace when the step
completes.
The error `trace (2) != breakpoint (3)` confirms this, the thread that
should have reported breakpoint as its stop reason instead reports
trace, because an unwanted `StepOverBreakpoint` plan was pushed on it
and completed.
The newly added code fixes it by only popping plans that have
`GetDeferReenableBreakpointSite() == true`

[llvm] Avoid resolving `.incbin` during symbol collection (#172920)
With IO sandboxing enabled, Clang requires all FS accesses happen
through the one "true" VFS instance. That instance is currently not
being propagated into the assembly parser, and doing so would be super
involved. This triggers sandbox violations whenever an `.incbin`
directive is encountered, since the parser needs the VFS to open the
file.
However, it seems that `asm()` directives are only parsed to get the
symbols of an LLVM module, which cannot be affected by `.incbin`
directives. This PR adds an option to the asm parser to avoid resolving
`.incbin` directives when collecting module symbols, avoiding the
sandbox violation.

## Description
Fix minor typos and incorrect comments in the APINotes subsystem (No
functional code is modified)
## Changes Made
- **`APINotesReader.h`** — Fixed `member buffer` → `memory buffer` in
the `Create()` doc comment (`Create()` takes a `llvm::MemoryBuffer`)
- **`APINotesFormat.h`** — Corrected the file header comment which
incorrectly referred to `APINotesWriter.h` instead of `APINotesFormat.h`
- **`APINotesYAMLCompiler.cpp`** — Fixed `it's` → `its` (possessive, not
a contraction)
- **`SemaAPINotes.cpp`** — Fixed `collection` → `collecting` and added a
missing `to` in `defer to the client to select`
## Motivation
First contribution to LLVM, aimed at getting familiar with the
contributing workflow.

[lldb][ARM] Support thread local variables on ARM Linux (#181315)
Currently, `DynamicLoaderPOSIXDYLD::GetThreadLocalData()` only supports
the TLS memory layout where the thread pointer register points to the
start of the `pthread` structure, and the address of the DTV pointer can
be calculated by adding the offset of the `dtv` field to `tp`. On ARM
(and AArch64), the thread pointer points directly to `dtv`. The patch
improves the detection of the actual memory layout in the method and
adjusts the calculations for the new case, thus adding support for
thread-local variables on ARM Linux.

[clang] Replace `finish()` with destructors for `DiagnosticConsumer` (#183831)
The `DiagnosticConsumer::finish()` API has historically been a source of
friction. Lots of different clients must manually ensure it gets called
for all consumers to work correctly. Idiomatic C++ uses destructors for
this. In Clang, there are some cases where destructors don't run
automatically, such as under `-disable-free` or some signal handling
code in `clang_main()`. This PR squeezes the complexity of ensuring
those destructors do run out of library code and into the tools that
already deal with the complexities of `-disable-free` and signal
handling.

[CMake] Propagate dependencies to OBJECT libraries in add_llvm_library (re-land) (#184201)
Previously, transitively inherited calls to
`target_include_directories(foo SYSTEM ...)` were being squashed into a
flat list of includes, effectively stripping off `-isystem` and
unintentionally forwarding warnings from such dependencies.
To correctly propagate `SYSTEM` dependencies, use
`target_link_libraries` to forward the parent target's link dependencies
to the OBJECT library (similar to the `_static` flow below). Unlike a
flat `target_include_directories`, this lets CMake resolve transitive
SYSTEM include directories through the proper dependency chain.
Note that `target_link_libraries` on an OBJECT library propagates all
usage requirements, not just includes. This also brings in transitive
`INTERFACE_COMPILE_DEFINITIONS`, `INTERFACE_COMPILE_OPTIONS`, and
`INTERFACE_COMPILE_FEATURES`. This is arguably more correct, as the
OBJECT library compiles the same sources and should see the same flags.
The existing `target_include_directories` call is retained for include
directories set directly on the target (not through link dependencies).
CMake deduplicates include directories that appear through both paths.
Compile definitions and options may technically appear twice (once via
the OBJECT library, once via the consuming target), but duplicate `-D`
and flag entries are harmless in practice.
Also fix `clang_target_link_libraries` and `mlir_target_link_libraries`
to forward the link type (PUBLIC/PRIVATE/INTERFACE) to `obj.*` targets.
Previously the type keyword was silently dropped, resulting in plain-
signature `target_link_libraries` calls. This is now required because
the new keyword-signature call in `llvm_add_library` would otherwise
conflict (CMake requires all calls on a target to use the same
signature).

[OpenMP][Offload] Handle `present/to/from` when a different entry did `alloc/delete`. (#165494)
OpenMP allows cases like the following:
```c
int *p1, *p2, x;
p1 = p2 = &x;
...
#pragma omp target_exit_data map(delete: p1[:]) from(p2[0])
```
Which means, when the runtime encounters the `from` entry, the ref-count
may not be zero, but it will go down to zero at the end of the current
construct, which should cause the "from" transfer to happen.
Similarly, a user may have:
```c
struct S {
int *p;
};
#pragma omp declare_mapper (id1: S s) map(s.p) map(present, alloc: s.p[0:10])
#pragma omp declare_mapper (id2: S s) map(s.p, s.p[0:10])
S s1;
// present-check should fail here
#pragma omp target_enter_data map(alloc: s.p[0:10]) map(mapper(id1), to: s)
// "to" should be honored here
#pragma omp target_enter_data map(alloc: s.p[0:10]) map(mapper(id2), to: s)
```
Where the allocation happens before the "to" entry is encountered by the
runtime. Or, an allocation happens before a "present" entry is
encountered.
To handle cases like this, we need to use the state information of
previously seen new allocations, deletions, "from" entries, when
honoring `to`/`from`/`present` map entries.

[LAA] Always use DepCands when grouping runtime checks. (#91196)
Update groupChecks to always use DepCands to try and merge runtime
checks. DepCands contains the dependency partition, grouping together
all accessed pointers to he same underlying objects.
If we computed the dependencies, We only need to check accesses to the
same underlying object, if there is an unknown dependency for this
underlying object; otherwise we already proved that all accesses withing
the underlying object are safe w.r.t. vectorization and we only need to
check that accesses to the underlying object don't overlap with accesses
to other underlying objects.
To ensure runtime checks are generated for the case with unknown
dependencies, remove equivalence classes containing accesses involved in
unknown dependencies.
This reduces the number of runtime checks needed in case non-constant
dependence distances are found, and is in preparation for removing the
restriction that the accesses need to have the same stride which was
added in https://github.com/llvm/llvm-project/pull/88039.

It is enabled by default for C++14 and C23, and the Scanner sets it
explicitly to always allow literals with digit separators in directives.

[CIR] Fix handling of cleanup scopes inside a try body (#183869)
We had a problem where scope terminators were not being created
correctly when a cleanup scope appeared inside the body of a try
operation. This was caused by cleanup scope operation not being properly
flushed before the try body scope was completed.
This change fixes the problem by creating a RunCleanupsScope in the
lambda that pupulates the try body and forcing cleanups before adding
the yield terminator to the try body.
The test case also exposed a secondary bug where we were not properly
updating the innermostEHScope variable when popping a cleanup from the
eh stack. That is also fixed here.

[CIR] Implement function/call attribute parsing (#184185)
It was brought to my attention that we didn't actually have a parsing
test/parsing failed when attributes were included. This patch adds the
parsing functionality for attributes, and sets them correctly, plus
makes sure we have a test that validates functions, member functions,
calls, member calls, and indirect calls.

[Coroutines] Replace struct alloca frame with byte array and ptradd (#178359)
Replace coroutine frame struct type with a simple byte array and use
offset-based ptradd operations instead of struct GEP for all field
access. Alloca types have largely lost all meaning to LLVM (even this
pass merged them and used an arbitrary type to represent all of them),
and so they just makes the code to construct alloca more difficult and
less flexible.
Key changes:
- Remove LayoutFieldIndex from frame field tracking
- Remove StructType usage - frame is now a byte array
- Replace all CreateStructGEP/CreateConstInBoundsGEP with CreatePtrAdd
- Store ResumeOffset/DestroyOffset in SwitchLowering for reuse
- Remove Shape.FrameTy, use Shape.FrameSize directly
Bug fix: Uses pointer size and alignment from data layout for header
pointer offsets in debug info instead of hardcoded 8 byte.
Optimization: Replaces load+store patterns with CreateMemCpy for copying
allocas to the frame more efficiently.
Optimization: Add missing inbounds annotations on existing ptradd calls.
Improvement: Preserve debug info of every alloca, even overlapping ones.
The frame type is now completely opaque at the IR level. All structure
is implicit through computed offsets. Debug info still provides detailed
field information using explicit offsets.

[flang] Recognize compiler directives after expansion in comment (#183626)
The compiler can recognize a compiler directive when one results from a
macro expansion at the beginning of a non-comment source line, as in
"#define FOO !$OMP". But it can't recognize a compiler directive that
initially appears as a comment line, as in "!BAR" after "#define BAR
$OMP". Extend the prescanner to recognize such cases in free form
source. (Fixed form is a much more complicated case for this recognition
and will be addressed later if needed.)
This is the 2nd version of this patch; the first was reverted after
problems with continuation lines were encountered.
Fixes https://github.com/llvm/llvm-project/issues/178481.

Reland "[OpenMP][Offload] Handle `present/to/from` when a different entry did `alloc/delete`." (#184260)
Some tests that were checking for prints inside/outside `target` regions
needed to be updated to work on systems where the ordering wasn't
deterministic.
Reverts llvm/llvm-project#184240
Original description from #165494:
-----
OpenMP allows cases like the following:
```c
int *p1, *p2, x;
p1 = p2 = &x;
...
#pragma omp target_exit_data map(delete: p1[:]) from(p2[0])
```
Which means, when the runtime encounters the `from` entry, the ref-count
may
not be zero, but it will go down to zero at the end of the current
construct,
which should cause the "from" transfer to happen.
Similarly, a user may have:
```c
struct S {
int *p;
};
#pragma omp declare_mapper (id1: S s) map(s.p) map(present, alloc: s.p[0:10])
#pragma omp declare_mapper (id2: S s) map(s.p, s.p[0:10])
S s1;
// present-check should fail here
#pragma omp target_enter_data map(alloc: s.p[0:10]) map(mapper(id1), to: s)
// "to" should be honored here
#pragma omp target_enter_data map(alloc: s.p[0:10]) map(mapper(id2), to: s)
```
Where the allocation happens before the "to" entry is encountered by the
runtime. Or, an allocation happens before a "present" entry is
encountered.
To handle cases like this, we need to use the state information of
previously
seen new allocations, deletions, "from" entries, when honoring
`to`/`from`/`present` map entries.

[CIR] Upstream basic CodeGen tests from incubator (#183998)
This PR upstreams `expressions.cpp` and `c89-implicit-int.c` from the
ClangIR incubator to the mainline.
Following the incremental approach discussed in #156747 and the feedback
from the closed PR #157333, I have:
1. Copied the files directly from the incubator to preserve history.
2. Updated the `RUN` lines to use the `--check-prefix=CIR` flag.
3. Converted `CHECK:` lines to `CIR:`.
4. Standardized variable captures using the `%[[VAR:.*]]` regex syntax
(in `expressions.cpp`).
Verified locally with `llvm-lit`. This is a partial fix for #156747.
*Note: As suggested in previous reviews, I am focusing only on the `CIR`
checks for now to keep the upstreaming incremental. OGCG/LLVM
verification can be added in a follow-up PR once the base tests land.*

available on the device, then clones the recipe init and copy regions
into the construct and replaces uses with the materialized alloca.
Optional destroy region is cloned before the region terminator.
- Private: Clones the recipe init region into the construct (at region
entry or at the loop op for acc.loop private). Replaces uses of the
recipe result with the materialized alloca. Optional destroy region is
cloned before the region terminator.
- Reduction: Creates acc.reduction_init (init region inlined) and
acc.reduction_combine_region (combiner region inlined). All uses of the
reduction in the region are updated to the reduction init result.
New operations
--------------
- acc.reduction_init: Allocates and initializes a private reduction
variable from a recipe. Takes the original reduction variable and
reduction_operator; has a single region that must yield one value (the
private storage) via acc.yield. Used by the pass to materialize
acc.reduction_recipe init regions inside the compute construct.
- acc.reduction_combine_region: Combines the private reduction value
with the shared reduction variable. Takes the shared and private
memrefs; has a single region (the recipe combiner) terminated by
acc.yield with no operands. Used by the pass to materialize the
reduction recipe combiner.
Both ops implement RegionBranchOpInterface. acc.yield is updated to
allow terminating ReductionInitOp and ReductionCombineRegionOp regions.
Supporting changes
------------------
- OpenACCUtilsLoop: Factor cloneACCRegionInto out of the existing
loop-conversion helper so the pass can clone recipe regions with
optional result replacement; loop conversion now calls the shared
helper.
- Flang: Add ReductionInitOpFortranObjectViewModel
(FortranObjectViewOpInterface) for acc.reduction_init and register it in
OpenACC extensions.
Tests
-----
- MLIR: acc-recipe-materialization-{firstprivate,private,reduction,
kernel-private,parallel}.mlir (memref dialect).
- Flang: acc-recipe-materialization-{firstprivate,firstprivate-derived,
private,reduction,kernel-private,parallel}.fir; firstprivate test has a
second RUN with -acc-optimize-firstprivate-map.

This PR addresses post-commit reviews in #182416
Previously, `RISCVMoveMerger` only identified and merged 32-bit moves
into a 64-bit GPRPair move if the even-indexed register most appeared
before the odd-index register move.
This patch extends the pass by disregarding the order of even/odd-index
pair.

[LIT] Use forward slashes in substitutions when LLVM_WINDOWS_PREFER_FORWARD_SLASH is set (#179865)
When building with `-DLLVM_WINDOWS_PREFER_FORWARD_SLASH=ON`, tools like
lld output paths with forward slashes on Windows. However, lit's default
substitutions (`%t`, `%p`) typically use backslashes on Windows, causing
FileCheck failures in tests that strictly match path separators.
This patch propagates the `LLVM_WINDOWS_PREFER_FORWARD_SLASH` build flag
to llvm-lit via `builtin_parameters`. It also updates lit's TestRunner
to respect the 'use_normalized_slashes' parameter. When enabled, lit
normalizes paths in substitutions to use forward slashes, ensuring that
test expectations align with the tool output.
With this fix, the number of failed tests with
`-DLLVM_WINDOWS_PREFER_FORWARD_SLASH=ON` changes as follow:
- The total number of failed tests: 303 -> 168
- Break down:
- `Builtins-i386-windows` tests: 99 -> 0
- `Clang` tests: 28 -> 5
- `Clang Tools` tests: 7 -> 1
- `LLVM` tests: 6 -> 4
- `lld` tests: 2 -> 0
- Other failed tests:
- `glang`: 1
- `Clang-Unit`: 5
- `Clangd`: 3
- `Clangd Unit Tests`: 150
- `LLVM-Unit`: 1

[RISCV][NFC] Prepare for Short Forward Branch of branches with immediates (#182456)
This NFC patch introduces two key updates:
- It replaces the `gpr` operand type with `sfb_rhs` for the `rhs`
operand in the short forward branch optimization pseudos. The `sfb_rhs`
type supports both register and immediate operands.
- It updates the pseudos to use branch opcodes instead of condition
codes, which were used prior to this change.
Together, these changes prepare the existing codebase to support short
forward branches that compare a register with an immediate value.
Currently, short forward branch support is limited to
register-to-register comparisons

[Clang][NFCI] Initialize PredefinedNames immediately (#183295)
In isPredefinedUnsafeLibcFunc the set of predefined names is initialized
lazily. However, this pattern is redundant as function-scope static
variables are initialized on first pass through the control flow. This
commit makes the variable constant, makes it a non-heap object, and
initializes it immediately. This has the following benefits:
- The initialization pattern cleaner and potentially easier for the
compiler to optimize.
- Making the variable const avoids it being used as mutable global
state.
- Having immediate initialization removes a potential race condition.

[AMDGPU] IGroupLP: Refactor SchedGroup::initSchedGroup (NFC) (#184122)
There are three overloaded SchedGroup::initSchedGroup functions, two of
which are only used for specific types of SchedGroups, namely
SCHED_BARRIER and SCHED_GROUP_BARRIER. This seems to have a led to some
confusion since the different functions perform checks which are not
needed for their intended restricted use cases. Furthermore, there are
several wrong comments surrounding those functions.
Simplify the functions and inline the actual initialization parts of the
SCHED_BARRIER and SCHED_GROUP_BARRIER variants at their only call sites.
Extract a function that finds the candidate SUnits for a given
SchedGroup and use this instead of initSchedGroup. Fix comments.

[AMDGPU] IGroupLP: Avoid repeating reachability checks in greedy algorithm (#182463)
In the greedy pipeline solver, the group cost is found using the
addEdges function and the edges must be removed from the DAG after
processing each group. The best group edges are then reinserted using
the same function. This repeats the costly reachability checks inside
the function which become problematic for pipelines with many
SchedGroups.
The algorithm is changed to remember the best group edges instead of
recomputing them. Additionally, SchedGroup::tryAddEdge is refactored to
avoid a redundant cycle check which is already performed by DAG->addEdge.

[lldb] Use AppendMessageWithFormatv in ComandObjectWatchpoint (#184128)
All of the AppendMessage... methods of CommandReturnObject automatically
add a newline, apart from AppendMessageWithFormat. This gets very
confusing when reviewing changes to commands.
While there are use cases for building a message as you go, controlling
when the newline is emitted, a lot of calls to AppendMessageWithFormat
include a newline at the end of the format string.
Such as in the watchpoint commands. So I've converted them to equivalent
AppendMessageWithFormatv calls so that:
* They have the less surprising behaviour re. newlines.
* They are in many cases more readable than the printf style notation.

[mlir][llvm] Fix crash in LLVM inliner when callee has no recognized terminator (#183949)
When the callee of an llvm.call has a body block ending with an
unregistered op (rather than a recognized LLVM terminator like
llvm.return), the LLVM inliner's handleTerminator method was called with
that unregistered op and crashed via a cast<LLVM::ReturnOp>() assertion
or use-after-erase due to unresolved call result uses.
The root cause is that the generic MLIR verifier conservatively treats
unregistered ops as potential terminators (using mightHaveTrait), so
malformed IR of this shape passes verification. The inliner, however,
assumes that the callee's terminator is a recognized LLVM op.
Fix by adding a guard in LLVMInlinerInterface::isLegalToInline() that
refuses to inline a callee containing any block whose last operation
does not have the IsTerminator trait. This prevents the crash and leaves
the call site intact without any IR mutation.

[AArch64] Add vector expansion support for ISD::FCBRT when using ArmPL (#183750)
This patch teaches the backend how to lower the FCBRT DAG node to the
vector math library function when using ArmPL. This is similar to what
we already do for llvm.pow/FPOW, however the only way to expose this is
via a DAG combine that converts
FPOW(<2 x double> %x, <2 x double> <double 1.0/3.0, double 1.0/3.0>)
into
FCBRT(<2 x double> %x)
when the appropriate fast math flags are present on the node. I've
updated the DAG combine to handle vector types and only perform the
transformation if there exists a vector library variant of cbrt.

[NFC][AArch64] Refactor Arm llvm-mca tests (#183294)
This patch refactors the llvm-mca tests for AArch64 targets
which make use of the shared "Neoverse/Inputs" directory. For the
sake of making scaling easier, the "Inputs" directory is now on the
toplevel at llvm-mca/AArch64 and all tests referencing this directory
are rewritten to use the new path.

[mlir][xegpu] Fix crash in XeGPUPropagateLayout when module has llvm.func (#183899)
updateFunctionOpInterface() called
funcOp.setType(FunctionType::get(...)) on every FunctionOpInterface
operation, including llvm.func. However, llvm.func stores its type as
LLVMFunctionType, not the standard FunctionType. Calling
setType(FunctionType{}) on it corrupts the function_type attribute, and
the next call to getFunctionType() (which tries to
cast<LLVMFunctionType> the stored attribute) aborts.
Fix by skipping functions whose type is not a standard FunctionType.
XeGPU layout propagation only applies to functions using MLIR's
FunctionType; other function types (like LLVMFunctionType) are not
expected to carry XeGPU layouts.

[mlir][func] Move return-type verification from ReturnOp to FuncOp (#184153)
Move the operand count and type checks for func.return from
ReturnOp::verify() into a new FuncOp::verify(). The verifier iterates
all blocks in the callable region, skipping terminators that are not
func.return (e.g. llvm.return or test.return that may appear during
dialect conversion).
Fix several invalid-IR tests that had func.func return types
inconsistent with the actual func.return operands. Previously these
mismatches were silent because block verification stopped at an earlier
expected error before reaching the func.return; now that
FuncOp::verify() runs before body verification, the return types must be
consistent.

[mlir][XeGPU] Fix crash in getUArch when no chip target attribute is set (#183912)
When running --xegpu-subgroup-distribute (or --xegpu-propagate-layout)
on a gpu.func that lacks a chip target attribute, getChipStr() returns
std::nullopt and the callers pass an empty string to getUArch(). This
function used llvm_unreachable for unrecognised architecture names,
causing an immediate abort instead of gracefully skipping the operation.
Fix by:
1. Changing getUArch() to return nullptr for unknown arch names instead
of calling llvm_unreachable.
2. Adding null-pointer guards to all callers in XeGPUPropagateLayout.cpp
that were missing them. The callers in XeGPUSubgroupDistribute.cpp
already had null checks but they were unreachable due to the unreachable
call.
Add a regression test that runs --xegpu-subgroup-distribute on a
gpu.func without any chip attribute and verifies it no longer crashes.

[mlir][XeGPU] Fix crash in wg-to-sg type converter on non-XeGPU tensors (#183914)
The SCF structural type conversion in XeGPUWgToSgDistributePass
registered a RankedTensorType conversion callback that unconditionally
called VectorType::get() on the tensor's shape. If the tensor had
dynamic dimensions (e.g. tensor<?xi32>) and no XeGPU layout encoding,
getSgShapeAndCount() returned the original shape intact (including the
kDynamic sentinel value), causing VectorType::get() to abort because
VectorType does not support dynamic sizes.
Fix by checking whether the RankedTensorType carries an XeGPU LayoutAttr
encoding before attempting the conversion. Plain tensors without such an
encoding are left unchanged (std::nullopt causes the passthrough
converter to handle them).
Add a regression test for the no-encoding / dynamic-tensor case.

[mlir][VectorToXeGPU] Fix crash on memref with non-scalar element type (#183905)
The vector.store and vector.load lowering in --convert-vector-to-xegpu
would crash when the source memref had a non-integer/float element type
(e.g. memref<?xvector<4xf32>>).
The crash occurred inside createNdDescriptor() when computing the byte
offset for dynamic memrefs: srcTy.getElementTypeBitWidth() internally
calls getIntOrFloatBitWidth() which asserts on non-scalar types such as
vector<4xf32>.
Fix by adding a check for the memref's element type in
storeLoadPreconditions(). If the element type is not an integer or
float, the pattern returns notifyMatchFailure() instead of proceeding
and crashing.
The same guard is applied to TransferReadLowering and
TransferWriteLowering which share the same helper and can hit the same
path.

sparse_tensor.foreach over a rank-0 (scalar) dense tensor crashed

one loop level per tensor dimension. For rank-0 tensors no loops are

Add a rank-0 early-return path in ForeachRewriter::matchAndRewrite that
handles dense scalar tensors directly: bufferize the input to a rank-0
memref, load the single element with empty indices, then inline the body
block exactly once. Reduction block-argument values in the yield are
remapped to their post-inline equivalents before the block is inlined to
avoid dangling references.
Sparse rank-0 tensors are left as a notifyMatchFailure (genuinely
unsupported, no crash).

[mlir][sparse] Reject dense level after non-unique level in encoding verifier (#184157)
The sparse tensor iteration model for dense levels requires exactly one
parent position to linearize into a contiguous range. However, when a
non-unique level (e.g. compressed(nonunique)) precedes a dense level,
the DedupIterator provides a two-element cursor {posLo, segHi}, causing
DenseLevel::peekRangeAt to assert and crash with:
Assertion `parentPos.size() == 1 && "Dense level can not be
non-unique."'
Fix this by adding a check in SparseTensorEncodingAttr::verify that
rejects any encoding where a dense level directly follows a non-unique
level, emitting a proper diagnostic instead of crashing during lowering.

[mlir][sparse] Fix use-after-free crash in SparseSpaceCollapsePass (#184001)
The `SparseSpaceCollapsePass::runOnOperation()` was calling
`collapseSparseSpace()` inside the `func->walk(...)` callback. The
collapse erases the outer `IterateOp` (and all its nested ops including
inner `ExtractIterSpaceOp`s), while the walk iterator still holds a
reference to one of those nested ops as its current position. The walk
then tries to advance to the next op, which has already been freed,
causing a segfault.
Fix this by collecting all collapsable groups during the walk without
mutating the IR, then processing them after the walk completes.

[DAG] isKnownNeverZero - add ISD::OR DemandedElts handling (#183228)
This patch updates `SelectionDAG::isKnownNeverZero` to support `ISD::OR`
by forwarding the `DemandedElts` mask to its operands.
Previously, `ISD::OR` dropped the mask, causing the compiler to be
overly conservative if any lane in the vector was zero, even if that
lane wasn't demanded. This change allows the compiler to prove a vector
result is non-zero even if ignored lanes are zero.
Fixes #183037
**Tests:**
- Moved tests from the C++ file to the IR assembly file
(`known-never-zero.ll`) as requested.
- Confirmed the code now correctly tracks which parts of a vector are
actually needed for `ISD::OR`.
- This allows the compiler to prove a result is "never zero" even if
some unused lanes contain zeros.

[mlir][Vector][GPU] Distribute expanding `shape_cast` ops (#183830)
The initial implementation of `shape_cast` distribution only focused on
scenarios with collapsing shape casts. Within downstream pipelines such
as IREE, commit 962a9a3 exposes an issue with this implementation, where
the rank-expanding cast ops (stemming from the new `vector.broadcast`
canonicalization) silently fall through to the "collapsing-or-no-op"
logic. This brings about bugs with rank mismatches and firing validation
assertions when distributing rather common reshaping sequences
encountered after CSE/ canonicalization, such as below:
```
// Example 1: gather op
%weight = arith.constant dense_resource<__elided__> : tensor<256xi8>
%c0 = arith.constant 0 : index

This commit adds initial handling of expanding `shape_cast`s, going
through the three scenarios:
- if all "excess" dimensions in the front of the destination shape are
unit, it's clear that the work is not distributed across those, so we
strip the same number of unit dimensions from the per-lane yielded type;
- if the source type within the warp code is of rank 1, we still
determine the corresponding output type cleanly by multiplying the
dimensions of the per-lane yield type;
- if neither of the above are true, explicitly fail the pattern for such
expanding `shape_cast`'s. Dimension-specific distribution parameters are
deemed ambiguous, at least from within this pattern's context.

[VPlan] Preserve IsSingleScalar for sunken predicated stores. (#184329)
The predicated stores may be single scalar (e.g. for VF = 1). We should
preserve IsSingleScalar. As all stores access the same address,
IsSingleScalar must match across all stores in the group.
This fixes an assertion when interleaving-only with sunken stores.

[Clang] Fix clang crash for fopenmp statement(for) inside lambda function (#146772)
C++ range-for statements introduce implicit variables such as `__range`,
`__begin`, and `__end`. When such a loop appears inside an OpenMP
loop-based directive (e.g. `#pragma omp for`) within a lambda, these
implicit variables were not emitted before OpenMP privatization logic
ran.
OMPLoopScope assumes that loop-related variables are already present in
LocalDeclMap and temporarily overrides their addresses. Since the
range-for implicit variables had not yet been emitted, they were treated
as newly introduced entries and later erased during restore(), leading
to missing mappings and a crash during codegen.
Fix this by emitting the range-for implicit variables before OpenMP
privatization (setVarAddr/apply), ensuring that existing mappings are
correctly overridden and restored.
This fixes #146335

* "test/CodeGen/AArch64/neon-intrinsics.c"
and moved to:
* "test/CodeGen/AArch64/neon/intrinsics.c".
The following helper hooks were adapted from the ClangIR project:
* `getNeonType`, `emitNeonCall`, `emitNeonCallToOp`.
Credit to the ClangIR contributors for the original implementation.

bx lr
The bxaut instruction is available when for thumb2 code with the
armv8.1m-main architecture and PACBTI is enabled
This change introduces a new pseudo instruction ARM::t2BXAUT_RET which
is similar to the existing pseudo instruction ARM::tBX_RET.

[clang-doc] Add basic benchmarks for library functionality (#182620)
clang-doc's performance is good, but we suspect it could be better. To
track this with more fidelity, we can add a set of GoogleBenchmarks that
exercise portions of the library. To start we try to track high level
items that we monitor via the TimeTrace functions, and give them their
own micro benchmarks. This should give us more confidence that switching
out data structures or updating algorthms will have a positive
performance impact.
Note that an LLM helped generate portions of the benchmarks and
parameterize them. Most of the internal logic was written by me, but
the LLM was used to handle boilerplate and adaptation to the harness.

[clang-doc] Improve complexity of Index construction (#182621)
The existing implementation ends up with an O(N^2) algorithm due to
repeated linear scans during index construction. Switching to a
StringMap allows us to reduce this to O(N), since we no longer need to
search the vector.
The `BM_Index_Insertion` benchmark measures the time taken to insert N
unique records into the index.
| Scale (N Items) | Baseline (ns) | Patched (ns) | Speedup | Change |
|----------------:|--------------:|-------------:|--------:|-------:|
| 10 | 9,977 | 11,004 | 0.91x | +10.3% |
| 64 | 69,249 | 69,166 | 1.00x | -0.1% |
| 512 | 1,932,714 | 525,877 | 3.68x | -72.8% |
| 4,096 | 92,411,535 | 4,589,030 | 20.1x | -95.0% |
| 10,000 | 577,384,945 | 12,998,039 | 44.4x | -97.7% |
The patch delivers significant improvements to scalability. At 10,000
items, index construction is **~44 times faster**, confirming the
complexity reduction from O(N^2) to O(N). The crossover point where the
new map-based approach beats the vector-based approach appears to be
around N=64.
Since the index is typically larger than 64 for files of non trivial
complexity, and users will typically be building documentation for an
entire project with many files, all normal usage should benefit from
this change.
Other benchmarks show minor regressions, though in a typical build of
LLVM documentation index construction takes up a larger amount of
runtime than any of these other components.

[libc] Extend check-libc-lit to cover include, integration, and all src tests (#184366)
The lit-based test runner introduced in c776a52f only discovered
libc.test.src tests with a strict __unit__.__build__ or
__hermetic__.__build__ suffix. This missed four categories of tests:
1. libc.test.include.* tests (e.g. isnan_test, signbit_test)
2. libc.test.integration.* tests (e.g. pthread, unistd, startup)
3. libc.test.src.* tests that have no __unit__/__hermetic__ marker (e.g.
errno_test, dirent_test, htonl)
4. libc.test.src.* tests with extra option suffixes between the type
marker and .__build__ (e.g. __unit__.__NO_FMA_OPT.__build__)
Wire up the two missing build dependencies so that check-libc-lit builds
include and integration tests before running them, and update
_isTestExecutable() to recognise all four patterns.
The pattern documentation was consolidated into the _isTestExecutable()
docstring, where it is next to the code it describes, to avoid the two
diverging in future.
Tested:
Compared the test count from a full `ninja check-libc` run (2765 tests)
against `llvm-lit --show-tests libc/test` after this change and
confirmed the counts match exactly.

[mlir][linalg] Upstream PackOp/UnPackOp's generateScalarImplementation. (#182838)
The revision upstreams the implementation from IREE. The ops were
upstreamed some time ago, and they are the remaining implementation. The
core implementation is mirrored from IREE and some cleanups and style
nits are fixed.
The mirror is not a pure copy-paste because the op accessors are
different:
| IREE | llvm-project |
|------|--------------|
| `getInputRank()` | `packOp.getSourceRank()` |
| `getOutputRank()` | `packOp.getDestRank()` |
| `getInput()` | `packOp.getSource()` |
| `getOutput()` | `packOp.getDest()` |
And it uses `linalg::createOrFoldDimOp` and `createFoldedDimOp` from
upstream to create DimOp ops.

[VPlan][NFC] Remove unnecessary explicit copy constructors (#183863)
VPHierarchicalChildrenIterator has explicitly defined copy and copy
assignment constructors which perform the same operation as the implicit
versions would. As a result, it does not follow the rule of three style,
but also does not need a destructor. This patch avoids that by simply
removing the explicit definitions, since their functionality is the same
as the implicit ones.

simply identify the cases that skip this support and fix it.

[MLIR][Canonicalization] Add shape_cast folding patterns (#183061)
### Summary
This PR adds two shape_cast-related canonicalization patterns for
`vector.to_elements` and `vector.from_elements`.
### Details
- Added` ToElements(ShapeCast(X)) -> ToElements(X)` as an in-place fold
in `ToElementsOp::fold`.
- Added `ShapeCast(FromElements(X)) -> FromElements(X)` as an
`OpRewritePattern` — it must be a pattern (not a `fold`) because we have
to create new op `FromElementsOp` with updated result type. This cannot
be done with a `fold`, because `fold` cannot create new ops and the
existing `FromElementsOp` result type differs from the `ShapeCastOp`
result type. Mutating the `FromElementsOp` (not root op) would violate
the `fold` contract and break other users.
- Added lit tests for the both ops (new `vector-to-elements.mlir`,
`vector-from-elements.mlir`)

[WebAssembly][FastISel] Call materializeLoadStoreOperands in load fold (#184203)
The `tryToFoldLoadIntoMI` function omitted materializing base registers
for addresses before folding sign-extend instructions into loads. This
left `$noreg` as the base register, crashing subsequent passes.
WebAssembly memory instructions structurally require a valid base
register. Calling the existing `materializeLoadStoreOperands` function
ensures that a `CONST 0` virtual register is generated when addressing
global variables directly without a pre-existing base register.
(before) %1:i32 = LOAD8_S_I32_A32 0, @ch, $noreg ... -> CRASH (after)
%3:i32 = CONST_I32 0
%1:i32 = LOAD8_S_I32_A32 0, @ch, %3:i32 ... -> Folded safely

[LifetimeSafety] Use per-container invalidation rules to fix false positives (#183000)
- Refactor `isContainerInvalidationMethod()` to per-container
invalidation sets, based on
https://en.cppreference.com/w/cpp/container#Iterator_invalidation.
- Follow reference invalidation rules instead of iterator invalidation
rules. Specifically:
- Methods that only invalidate iterators but not references are excluded
(e.g. `deque::push_back`, `unordered_map::emplace`).
- Methods that only invalidate references to the removed element itself
are excluded (e.g. `vector::pop_back`, `deque::pop_*`, and
`erase`/`extract` on all node-based containers).
- Fix false positives for `insert`/`emplace` etc on ordered associative
containers (`set`, `map`, `multiset`, `multimap`), which never
invalidate iterators per the standard.
- Add previously missing methods: `emplace_hint`, `insert_or_assign`,
`push_range`, `replace_with_range`, `resize_and_overwrite`, `merge`.
- `operator[]` now only invalidates for `flat_map`. `map::operator[]`
and `unordered_map::operator[]` may insert but don't invalidate
references.
Fixes #181912

[CIR] Handle vtable pure and deleted virtual functions (#183862)
Finding reproducers for these that don't use the deferred vtable (which
we haven't yet implemented) was a bit of a challenge, but I found
this setup to get these to be emitted. Fortunately it is a quite easy
implementation that doesn't do awfully much.
This patch implements both, plus the name through the itanium ABI.

As a GNU extension, clang supports math on void* and function pointers
in C mode only. From a CIR perspective, it makes sense to leave these
types in the IR, since it might be useful to do analysis.
During lowering, we already properly lower these to a size-1 element, so
there is no changes that need to happen besides letting this get through
CIR generation. This patch does that, plus adds some tests.

[HLSL][SPIRV] Fix `faceforward` pattern matcher logic (#183630)
Fixes a logic issue in the `faceforward` pattern matcher in
`SPIRVCombinerHelper.cpp`.
Previously when `mi_match` failed, we would still go through the nested
`Pred == CmpInst::FCMP_OGT || Pred == CmpInst::FCMP_UGT` check. It was
possible that whatever garbage was in Pred could randomly pass this
check and make us continue through the code. This change fixes that
logic issue by returning false as soon as `mi_match` fails.
Likely fixes #177803. Can't confirm since it seems another change has
obscured the crash.

[RISCV] Fix type inference ambiguity in SwapSysReg pattern (#184305)
Issue:
Building RISCVInstrInfo.td fails with the following TableGen error
during the generation of RISCVGenInstrInfo.inc:
` error: In test: Could not infer all types in pattern!`
Root Cause:
The riscv_swap_csr node has a polymorphic result type (i32 or i64
depending on the target architecture). When used inside the SwapSysReg
class pattern, TableGen's type inference engine cannot automatically
deduce the exact return type solely from the GPR:$rd output, leading to
the ambiguity error.
Fix:
This patch resolves the type ambiguity by explicitly wrapping the
riscv_swap_csr node with XLenVT, allowing TableGen to infer the types
correctly.

Substantial amounts of this PR were created using agentic AI tools, but

Roughly 10 years ago, in aacb80853a46bd544fa76a945667302be1de706c, Greg
deleted the call to delete g_debugger_list_ptr because of a race
condition:
> Fixed a threading race condition where we could crash after calling
Debugger::Terminate().
>
> The issue was we have two global variables: one that contains a
DebuggerList pointer and one that contains a std::mutex > pointer. These
get initialized in Debugger::Initialize(), and everywhere that uses
these does:
>
> if (g_debugger_list_ptr && g_debugger_list_mutex_ptr)
> {
> std::lock_guard<std::recursive_mutex>
guard(*g_debugger_list_mutex_ptr);
> // do work while mutex is locked
> }
>
> Debugger::Terminate() was deleting and nulling out g_debugger_list_ptr
which meant we had a race condition where someone might do the if
statement and it evaluates to true, then another thread calls
Debugger::Terminate() and deletes and nulls out g_debugger_list_ptr
while holding the mutex, and another thread then locks the mutex and
tries to use g_debugger_list_ptr. The fix is to just not delete and null
out the g_debugger_list_ptr variable.
However, this isn't necessary as long as we persist ("leak") the mutex
and always check it first. That's exactly what this patch does. Without
it, the assert in Debugger::Initialize is incorrect.
```
assert(g_debugger_list_ptr == nullptr &&
"Debugger::Initialize called more than once!");
```

[CIR] Split cir.binop into separate per-operation binary ops (#184227)
Replace the single `cir.binop` operation (dispatched via a `BinOpKind`
enum) with nine distinct ops — `cir.add`, `cir.sub`, `cir.mul`,
`cir.div`, `cir.rem`, `cir.and`, `cir.or`, `cir.xor`, and `cir.max` —
each with precise type constraints and only the attributes it needs
(nsw/nuw/sat on add/sub via `BinaryOverflowOp`).
A new `BinaryOpInterface` provides uniform `getLhs`/`getRhs`/`getResult`
access for passes and analyses.
The monolithic switch-based CIRToLLVMBinOpLowering is replaced by per-op
patterns generated through the existing CIRLowering.inc TableGen
infrastructure, with shared dispatch factored into two helpers:
`lowerSaturatableArithOp` for add/sub and `lowerIntFPBinaryOp` for
div/rem.

[lldb] Fix the GoogleTest teardown in the DAP unit tests (#184262)
Some of the DAP tests define a static method named `TeatUpTestSuite`
which is calling `SBDebugger::Terminate`. Besides the typo, the correct
method is `TearDownTestSuite`, which GoogleTest calls after running the
last test in the test suite.
When addressing this, I realized that currently you can't really call
Initialize and Terminate multiple times in the same process. This
depends on:

Register 33 is ELR_mode, which isn't defined as a register in any of the

tehy allow code running in one Debugger to mess with Targets from
another Debugger. The only use is Process::SetProcessExitStatus which
isn't actually used.

Which is under discussion in

Add new options -ffixed_r{8-15} for clang X86 target, like option
"-ffixed_x" for RISCV/AArch64 target.
Also, add target-feature +reserve-r{8-15} for the X86 backend.
The registers which are specified reserved will not be used in
RegAlloc/CalleeSave. Then the reserved registers can be maintained by
user. It will be useful for the runtime/interpreter implementation.
Other registers are used in specific instructions or mechanism, so they
can't be reserved.

[WebAssembly] Use MVT::i32 instead of i1 in performAnyAllCombine (#183866)
The CombineSetCC helpers and performAnyAllCombine generate MVT::i1

However MVT::i1 is an illegal type in WebAssembly, and this combiner can
run either before or after legalization. Directly creating the intrinsic
and negating its result using XOR instead of i1 and a NOT operation
avoids this problem.

```
Some original work was done around this in
df1d786c460e0e47c9074f3533f098190ebfbc1b, which was then done in
upstream Google benchmark in
https://github.com/google/benchmark/commit/d8db2f90b643eb28a12976beb4d57bcfb639911d.
The original work done in the patch implementing this feature doesn't
seem to account for as many cases as the upstream patch does. This patch
reverts the diff in df1d786c460e0e47c9074f3533f098190ebfbc1b and applies
the applicable hunks from the upstream patch.

[GVN] Fix crash when svcount is used with globals-aa (#184347)
When -globals-aa is used, `analyzeLoadAvailiability` calls
`analyzeLoadClobberringStore` which in turn calls
`isFirstClassAggregateOrScalableType` which is using
`isa<ScalableVectorType>`. Ideally it should use type's isScalableType()
method.
The crash does not occur when default (BasicAA) is used because
`analyzeLoadAvailiability` function does not take the load clobbering
path as BasicAA returns `Def`.

[RISCV] Sink instructions so AVL dominates in RISCVVLOptimizer (#184155)
The last feature that RISCVVectorPeephole::tryToReduceVL has that
RISCVVLOptimizer doesn't is that if the vl to reduce to doesn't dominate
a vector pseudo, it can sink the pseudo below the vl definition if it's
safe to do so.
This PR shares the logic to check for physical register clobbering in
RISCVInstrInfo, but there may be a better place for it.
The DemandedVLs DenseMap needs to be switched to a MapVector to get
deterministic ordering, since the order in which we sink instructions
can affect the resulting codegen.
This helps removes a few vsetvli toggles in llvm-test-suite.

[MC][test] Add relax-branch-align.s demonstrating unnecessary branch relaxation (#184551)
The two-pass relaxation approach (relaxFragment, then layoutSection)
can unnecessarily relax a backward branch from short (2B) to near (5B).
When a forward branch relaxes (2B->6B), it shifts the backward target
by +4B. A .p2align between target and source absorbs this growth. The
true displacement is -125 (fits short), but the two-pass approach
evaluates the backward branch with stale target offsets, seeing -129
(beyond [-128,127]) and relaxing it unnecessarily.

[ELF] Add target-specific relocation scanning for LoongArch (#182236)
Implement LoongArch::scanSectionImpl, following the pattern established
for x86, PPC64, SystemZ, AArch64. This merges the getRelExpr and TLS
handling for SHF_ALLOC sections into the target-specific scanner,
enabling devirtualization and eliminating abstraction overhead.
- Inline relocation classification into scanSectionImpl with a switch
on relocation type, replacing the generic rs.scan() path.
- Use processR_PC/processR_PLT_PC for common PC-relative and PLT
relocations.
- Inline TLS handling: IE->LE optimization for _PC_ variants only (not
_PCADD_ or absolute), TLSDESC->IE/LE for non-extreme code model,
GD/LD flag setting without going through generic handleTlsRelocation.
- Remove adjustTlsExpr by inlining its logic into scanSectionImpl.
- Remove LoongArch-specific code from Relocations.cpp:
handleTlsRelocation, execOptimizeInLoongArch, and the sort condition.
- Simplify getRelExpr to only handle relocations needed by
relocateNonAlloc, scanEhSection, and the extreme code model fallback
in relocateAlloc.

[MC] Fuse relaxation and layout into a single forward pass (#184544)
Replace the two-pass inner loop in relaxOnce (relaxFragment +
layoutSection) with a single forward pass that sets each fragment's
offset before processing it.
- Extract relaxAlign from layoutSection's FT_Align handling and call
it from relaxFragment. FT_Align padding is computed inline with the
tracked Offset, so alignment fragments always see fresh upstream
offsets. This structurally eliminates the O(N) convergence pitfall
where stale offsets caused each iteration to fix only one more
alignment fragment.
- The new MCAssembler::Stretch field tracks the cumulative upstream size
delta. In evaluateFixup, for PCRel fixups during relaxation, Stretch
is added to forward-reference target values (LayoutOrder comparison).
This makes displacement = target_old - source_old, identical to the
old two-pass approach, preventing premature relaxation for
span-dependent instructions.
- FT_Fill/FT_Org removed from relaxFragment; `if (F.Offset != Offset) in
the fused loop detects their size changes.
- layoutSection is retained for initial layout and post-finishLayout.
This fixes the FT_BoundaryAlign linear time convergence issue reported
by #176535. In addition, backward branches near the short/near boundary
may benefit from tighter encoding when a .p2align between the target and
the branch absorbs upstream growth (see relax-branch-align.s).

[AMDGPU] Add half vector support for table-driven libcall optimization (#178638)
When replacing certain AMDGPU library calls with constant data vectors,
the existing implementation only handled single and double-precision
floats. This change extends the functionality to also support
half-precision floats.
Additionally, it refactors the function responsible for generating
constant float data vectors to improve readability and reduces code
duplication. In tandem with this refactoring, the patch relaxes the
check for constant data vectors to include any constant of vector type.
This allows other constant vectors to be processed, such as those
created from constant aggregate zeros (e.g. `<2 x float>
zeroinitializer`).

[DA] Remove consistent flag from Dependence class (#181608)
The `Dependence` class has a flag `Consistent`, but it's not clear what
it represents. This flag doesn't seem to be updated correctly during
analysis. There are no users of it, so I think this flag would be
unnecessary.
In addition, because of this flag, even minor code changes can alter
test results unintentionally (specifically, the presence/absence of a
string "consistent" in the test output). Such test changes can be
confusing and gradually add to the maintenance burden.
Given these points, it's better to remove the `Consistent` flag from the
`Dependence` class entirely.

[SelectionDAG] Add expansion for llvm.convert.from.arbitrary.fp (#179318)
The expansion converts arbitrary-precision FP represented as integer
following these algorithm:
1. Extract sign, exponent, and mantissa bit fields via masks and shifts.
2. Classify the input (zero, denormal, normal, Inf, NaN) using the
exponent and mantissa fields.
3. Normal path: adjusting the exponent bias and left-shifting the
mantissa to fit the wider destination format.
4. Denormal path: normalizing by finding the MSB position of the
mantissa (via count-leading-zeros), computing the correct exponent from
that position, stripping the implicit leading 1, and shifting the
fraction into the destination mantissa field.
5. Assemble the destination IEEE bit pattern (sign | exponent |
mantissa) and select among the normal, denormal, and special-value
results.
Currently only conversions from OCP floats are covered, in LLVM terms
these are: Float8E5M2, Float8E4M3FN, Float6E3M2FN, Float6E2M3FN,
Float4E2M1FN.

[libc] Fix integration test args/env in LibcTest lit format (#184438)
Integration tests with ARGS or ENV in their add_integration_test() call
were being run with no arguments or environment variables by the
LibcTest lit format, causing failures in startup_args_test,
sprintf_size_test, getenv_test, execv_test, execve_test, and
getcwd_test.
Fix this by having add_integration_test() emit a sidecar
<executable>.params JSON file (via file(GENERATE)) whenever ARGS or ENV
are specified. LibcTest.execute() reads this file at test time and
passes the args and environment to the test executable.
Also always set PWD=exec_dir in the test environment so that
getenv("PWD") matches getcwd() for tests that compare them.

libclc: Reimplement amdhsa workitem functions (#184571)
These were quite out of date and broken. These were originally
implemented for clover, which at one point was aiming for HSA v2 ABI
near compatibility. Since clover has been removed, that path is dead.
This was also broken for the modern HSA ABIs. Update to assume the
v5 ABI.

This breaks a tie where the `SEXT_IN_REG` in an expression like
`SUB(0, SEXT_IN_REG(VECTOR_EXTRACT(..))` can fold into the `SUB` or the
`VECTOR_EXTRACT`. Currently, the `SUB` is always preferred, but it's
better to fold the `SEXT_IN_REG` into the `VECTOR_EXTRACT` extract,
which allows for `SMOV` to be used.

[lldb] Change more uses of AppendMessageWithFormat to AppendMessageWithFormatv (#184337)
When the message includes a final newline, Formatv can add that for you.
The only unusual change is one place in platform where we need to print
octal. LLVM doesn't have a built in way to do this (see
llvm/include/llvm/Support/FormatProviders.h) and this is probably the
only place in the codebase that wants to. So I decided not to add it
there.
Instead I've put the number info a format adapter with the normal printf
specifier, then put that into the Formatv format.

[clang] Predefine `_MSVC_TRADITIONAL` in MSVC compatibility mode (#184278)
As of version 19.15 (Visual Studio 2017 version 15.8), MSVC predefines
the `_MSVC_TRADITIONAL` macro to indicate whether it is using the old
"traditional" preprocessor or the new standards-conforming preprocessor.
Clang now predefines `_MSVC_TRADITIONAL` as 1 when emulating MSVC 19.15
or later, since Clang supports most traditional preprocessor behaviors
(e.g. `/##/` turning into `//`) when running in MSVC compatibility mode.
Currently there isn't a situation where it makes sense for Clang to
report `_MSVC_TRADITIONAL` as 0, since MSVC compatibility mode only
attempts to be compatible with the traditional MSVC preprocessor.
However, this does mean that clang-cl cannot match MSVC's behavior of
implicitly enabling the conforming C preprocessor when compiling with
`/std:c11`, `/std:c17`, or `/std:clatest`.

When a scf.while op has a loop-carried value whose type converts to
emitc::ArrayType (e.g. memref<1xf64>), the WhileLowering pattern
unconditionally called emitc::LValueType::get(arrayType), which
triggered an assertion because LValueType cannot wrap an array type.
Fix by returning a match failure in createVariablesForResults and
createVariablesForLoopCarriedValues when the converted type is an
emitc::ArrayType. This converts the crash into a proper legalization
failure.

[mlir][nvgpu] Fix crash in optimize-shared-memory pass with vector element types (#179111)
The `--nvgpu-optimize-shared-memory` pass crashed when processing
memrefs with vector element types (e.g., `memref<16x1xvector<16xf16>,
3>`). This occurred because getElementTypeBitWidth() calls
getIntOrFloatBitWidth(), which asserts the element type must be an
integer or float.
Thus, this PR adds an early-exit guard to return failure() when the
memref's element type is not a scalar int or float.
I wasn't sure if we should support vector types (by multiplying element
bit width by vector length) or just reject them. For now, I've
implemented it to return failure on non-scalar types.

[MLIR][Arith][Vector] Reject i0 integer type in arith and vector ops (#183589)
Add ODS type constraints that exclude zero-bitwidth integers (i0) from
operations in the arith and vector dialects. i0 has no meaningful
arithmetic representation and operations on it can trigger undefined
behavior (e.g. bitwidth calculations assuming non-zero width).
Changes:
- Add `AnyNonZeroBitwidthSignlessInteger` (as a `ConfinedType` over
`AnySignlessInteger`) and `AnyNonZeroBitwidthSignlessIntegerOrIndex`
to CommonTypeConstraints.td.
- Introduce `Arith_SignlessIntegerOrIndexLike` in ArithOps.td that wraps
`AnyNonZeroBitwidthSignlessIntegerOrIndex` via
`TypeOrValueSemanticsContainer`, and update
`SignlessFixedWidthIntegerLike`
to use `AnyNonZeroBitwidthSignlessInteger`. Replace all uses of the
shared `SignlessIntegerOrIndexLike` in ArithOps.td with the new
dialect-local constraint.
- Update `IndexCastTypeConstraint` to use
`Arith_SignlessIntegerOrIndexLike`.
- Update `BitcastTypeConstraint` to exclude i0 by composing the already-
defined `SignlessFixedWidthIntegerLike` and `FloatLike` constraints,
keeping the definition compact (3 alternatives instead of 7).
- Add `AnyVectorOfNonI0Elem` and `AnyVectorOfNonZeroRankNonI0Elem` in
VectorOps.td and apply them to `vector.contract`, `vector.reduction`,
`vector.multi_reduction`, `vector.outerproduct`, `vector.bitcast`, and
`vector.scan`.
- Update arith/invalid.mlir with explicit i0 rejection tests covering
all
integer op families (binary ops, cast ops, extended-multiply ops, cmpi,
bitcast, index_cast, index_castui) for both scalar and vector<N> forms.
- Update vector/invalid.mlir with i0 rejection tests for all covered
ops.
- Remove the now-invalid i0 canonicalization tests from
arith/canonicalize.mlir.

[mlir][Func] Use getMutableSuccessorOperands() in FuncOp verifier (#184589)
When verifying return-like terminators, use
getMutableSuccessorOperands() instead of getNumOperands() so that only
the operands passed to the parent region are checked against the
function result types. This handles terminators that implement
RegionBranchTerminatorOpInterface and carry additional operands for
other successor regions (e.g. loop back-edges).
Add tests using test.loop_block_term, which has both an iter operand
(passed back to the region) and an exit operand (passed to the parent).

Reproducer:
```

```
The cause is a pass ordering issue between the SCFToControlFlowPass and
CfgConversionPass
[here](https://github.com/llvm/llvm-project/blob/d0f50d55746aa27e6467cb2bce66596da9da065b/flang/lib/Optimizer/Passes/Pipelines.cpp#L239-L240).
I think they need to be run simultaneously somehow because the both SCF
and FIR structured operations may contain each other, and none will be
happy to get block CFG generated inside their region by the pass
lowering the other.
Reverting while this is sorted out.

[mlir][llvm] Fix SROA crash on empty LLVM struct types (#184596)
When SROA runs on an alloca of an empty struct type (llvm.struct<()>),
it crashes with:
Assertion `\!subelementIndexMap->empty()' failed.
The root cause is in LLVMStructType::getSubelementIndexMap(): for an
empty struct (no body fields), the loop doesn't execute and an empty
DenseMap is returned as a non-null optional. Later, getTypeAtIndex()
asserts the map is non-empty, triggering the crash.
Fix this by returning std::nullopt for empty structs, indicating they
cannot be destructured. This is consistent with how LLVMArrayType
handles the zero-element case.
Fixes #108366

[Flang][OpenMP] DEFAULT(NONE) error checking on implicit references (#182214)
A variable with an unspecified data-sharing attribute under a
DEFAULT(NONE) clause only emits an error if the variable is explicitly
referenced in the body of the construct with DEFAULT(NONE).
Ex:
```
!$omp parallel default(none)
!$omp task
a = 1
!$omp end task
!$omp end parallel
end
```
gfortran will error with `‘a’ not specified in enclosing ‘parallel’` on
the above. flang doesn't error.
Fix moves the error check to `CreateImplicitSymbols` and checks the
variable for a violation in any of its enclosing contexts.

The attributes `exclude_from_explicit_instantiation` and
`dllexport`/`dllimport` serve opposite purposes.
Therefore, if an entity has both attributes, drop one with a warning,
depending on the context of the declaration.
In a template context, the `exclude_from_explicit_instantiation`
attribute takes precedence over the `dllexport` or `dllimport`
attribute. Conversely, the `dllexport` and `dllimport` attributes are
prioritized, in a non-template context.

[TableGen] Complete the support for artificial registers (#183371)
Artificial registers were added in
eb0c510ecde667cd911682cc1e855f73f341d134
as a means of giving super-registers heavier weights than that
of their subregisters, even when they only contain a single
physical subregister.
Artifical registers thus do exist in code and participate in
register unit weight calculations, but are not supposed to be
available for register allocation.
This patch completes the support for artificial registers to:
- Ignore artificial registers when joining register unit uber
sets. Artificial registers may be members of classes that
together include registers and their sub-registers, making it
impossible to compute normalised weights for uber sets they
belong to.
We have a use case downstream relying on this being supported,
which allows to avoid introducing a large number of additional
register classes.
- Not generate purely artificial register class intersections.
It is critical not to have such classes, as the common LLVM
codegen infrastructure will try to use them to constrain
classes of virtual registers instead of producing COPYs
whenever both the source and target register classes contain
the same artificial registers.
- Not generate sub-classes where classes with the same
non-artificial members already exist. This is mostly for
convenience. For example, the HI16-capable subset of AMDGPU's
AV_32 is VGPR_32, except VGPR_32 also contains the artificial
staging registers. If the staging registers are not ignored,
we'll end up having an additional generated register class,
AV_32_with_hi16_in_VGPR_16, -- harmless, but also useless.
Eliminates a few inferred AMDGPU register classes:
- VS_32_with_hi16
- VS_32_Lo256_with_hi16
- VS_32_Lo128_with_hi16
- VRegOrLds_32_and_VS_32_Lo256
- VRegOrLds_32_and_VS_32_Lo128
- SRegOrLds_32_and_VRegOrLds_32
Causes no register class changes for other targets.

[SPIRV] Rename `selectSelectDefaultArgs` to `selectBoolToInt` (#184120)
The function is used to extend a `bool` (vector or scalar) into `1/-1`
for `true` and `0` for `false` (vector or scalar).
There is no obvious "default" argument for a select operation, so the
original name is confusing.
This patch:
* Renames this function to better signal its intention,
* makes the boolean argument explicit in the function (instead of
implicit through the first register operand of the instruction),
* rename `I` to `InsertAt`.

The optin.cplusplus.VirtualCall checker reports warnings for virtual

in a system header (included via -isystem). Users cannot fix such code
and must resort to NOLINT suppressions.
Add a system header check in checkPreCall before emitting the report,
consistent with how other checkers (e.g. MallocChecker) handle this.

Fixes https://github.com/llvm/llvm-project/issues/180155.
This is a duplicate of https://github.com/llvm/llvm-project/pull/180700
except that I also added some tests, fine to go with either PR, but we
should add the tests.
peekNextPPToken lexed a token and mutated MIOpt, which could clear the
controlling-macro state for main files in C++20 modules mode.
Save/restore MIOpt in Lexer::peekNextPPToken.
Add regression coverage in
LexerTest.MainFileHeaderGuardedWithCPlusPlusModules that checks to make
sure the controlling macro is properly set in C++20 mode.
Add source level lit test in miopt-peek-restore-header-guard.cpp that
checks to make sure that the warnings that depend on the MIOpt state
machine are emitted in C++20 mode.

The predicated loads may be single scalar (e.g. for VF = 1). We should
preserve IsSingleScalar when hoisting them. As all loops access the same
address, IsSingleScalar must match across all loads in the group.
This fixes an assertion when interleaving-only with hoisted loads.

[mlir][affine] Fix crash in vectorizeAffineLoopNest test utility for reduction loops (#184617)
The test utility function `testVecAffineLoopNest` called
`isLoopParallel` with a `reductions` output parameter, which populates
reduction descriptors when the loop performs a reduction. However, these
descriptors were never added to `strategy.reductionLoops` before calling
`vectorizeAffineLoopNest`. When the vectorizer then processed a loop
with `iter_args`, it found no reduction descriptors in the strategy and
hit an assertion failure.
Fix by registering the reduction loop descriptors in the strategy before
vectorization, matching what the production vectorizer code already does
correctly.

[mlir][shape] Fix crash when shape.lib array references undefined symbol (#184613)
In verifyOperationAttribute(), the single-symbol path for shape.lib used
SymbolTable::lookupSymbolIn() followed by an explicit null check. The
array path at line 196-197 used dyn_cast<FunctionLibraryOp>() directly
on the lookup result, which asserts when the symbol is not found (null
pointer).
Fix: use dyn_cast_or_null<> instead of dyn_cast<> so that a missing
symbol falls through to the existing "does not refer to
FunctionLibraryOp" error diagnostic instead of asserting.

[SPIRV] Fix global emission for modules with no functions (#183833)
Right now we have a problem where if you have a LLVM module with globals
but no functions, a completely empty SPIR-V module is emitted.
This is because global emission is dependent on tracking intrinsic
functions being emitted in functions.
As a simple fix, just insert a service function, which the backend is
already set up to not actually emit, if there are no real functions.
The current use case of the service function is for function pointers. I
don't think it's possible that we need to both generate a service
function for function pointers and for globals with no functions, so I
just added an error (not an assert) just in case if we do need it for
both cases.
Probably we should rework global handling in the future to work without
these workarounds, but this is a pretty fundamental issue so let's work
around it with this simple change for now.
This change exposed an existing bug:
We consider basic blocks with no successors as fall-through
Also, fix some existing tests. The symptom was:
We previously emitted an empty module, but not that we don't, we hit a
`spirv-val` error about invalid Function StorageClass for globals
because no `addrspace` was specified. Set the `addrspace` to `1`
(`CrossWorkgroup`) in those tests.

[mlir][Func] Fix FuncOp verifier ordering via hasRegionVerifier (#184612)
FuncOp::verify() iterated over all blocks and called
getMutableSuccessorOperands() on any RegionBranchTerminatorOpInterface
terminator to check return types. This ran during the entrance phase of
verification — before child ops had been verified — so a malformed
terminator whose getMutableSuccessorOperands() assumed invariants
established by its own verify() could crash instead of emitting a clean
diagnostic.
Fix by switching to hasRegionVerifier=1: rename verify() →
verifyRegions() so the return-type checks run in the exit phase, after
all nested ops have already been verified.
To demonstrate the bug and guard against regression, add
TestCrashingReturnOp to the test dialect. The op implements
RegionBranchTerminatorOpInterface and report_fatal_errors in
getMutableSuccessorOperands() when its 'valid' unit-attr is absent,
reproducing the class of crash described above. The accompanying lit
test confirms a clean diagnostic is emitted rather than a crash.

[DTU] fix dominator tree update eliding reachable nodes (#177683)

After inlining, it looks like this:
It should be sufficient to add and remove the edges shown in the test, i.e.:
- add: `bb3->bb1.i` and `bb3->bb2.i`
- remove: `bb3->bb4`, `bb3->bb5` and `bb5->bb8`
New nodes, like `bb5.body`, get discovered when adding bb3->bb2.i. See the "StepByStep" variant of the test). Without the fix in this patch, however, `bb5.body` gets elided when the deleted edges get taken into account, and `DT` is left invalid.

[X86] remove unnecessary movs when %rdx is an input to mulx (#184462)
Closes: https://github.com/llvm/llvm-project/issues/174912
When generating a `mulx` instruction for a widening multiplication, even
if one input is placed in %rdx, LLVM won't place it in the implicit
first slot, instead it'll generate two movs before calling mulx to swap
the registers, which are unnecessary. GCC already has this optimization
(as shown in the issue) so this puts the two compilers closer to each
other on that front.

The TDM base creation (amdgpu.make_tdm_base and

`%memref[%i0, %i1,, ...]` for the starting point of the tiles in
global/shared memory that the TDM descriptor refers to. Memory alias ops
can be safely folded into these operations, since these two memref
operands are just pointers to a scalar starting pint and don't have
semantics that depend on the memref layout (except to the extent that it
defines a location in memory).
While I'm here, I've cleaned up a few things, like the incorrect file
header and fixed the tests to not use integer address spaces.

[flang][OpenMP] Avoid implicit default mapper on pointer captures (#184382)
This change fixes incorrect implicit declare mapper behavior in Flang
OpenMP lowering.
Issue:
Implicit default mappers were being attached/generated for pointer-based
implicit captures, and also on data-motion directives. That could
trigger recursive component mapping that overlaps/conflicts with
explicit user mappings, causing runtime mapping failures.
Fix:
- Skip implicit default mapper generation for implicit pointer captures
(keep support for allocatables).
- Do not auto-attach implicit mappers on target enter data, target exit
data, or target update.
- Apply the same pointer guard in the implicit target-capture lowering
path.

[Hexagon] Use __HVX_IEEE_FP__ to guard protos that need -mhvx-ieee-fp (#184422)
Hexagon clang recently started to define __HVX_IEEE_FP__ when the

instructions that should only be available with -mhvx-ieee-fp with
__HVX_IEEE_FP__.
Additionally, the following NFC changes are included:
- NFC: Remove guards around HVX v60 intrinsic macros
Hexagon v60 is the oldest Hexagon version that supports HVX so these
guards were redundant. Presence of HVX is guarded separately, once
per the whole file.
- Remove comments from closing guards (HVX protos)
These comments served very limited function as they only guard
one macro. Also, they were incorrect. Instead of fixing remove them.
This will also reduce by the factor of two the amount of changes
when guarding conditions change.

[mlir][vector] Replace OneDimMultiReductionToTwoDim with OneDimMultiReductionToReduction (#184241)
The `OneDimMultiReductionToTwoDim` pattern had some issues. For the
input program:
```mlir
func.func @rank1_multi_reduction(%arg0: vector<8xf32>, %acc: f32) -> f32 {
%0 = vector.multi_reduction <add>, %arg0, %acc [0] : vector<8xf32> to f32
return %0 : f32
}
```
* when lowering using the inner-parallel strategy, the compiler would
essentially produce scalar code:
```mlir
func.func @rank1_multi_reduction(%arg0: vector<8xf32>, %arg1: f32) -> f32 {
%0 = vector.shape_cast %arg0 : vector<8xf32> to vector<1x8xf32>
%1 = vector.broadcast %arg1 : f32 to vector<1xf32>
%2 = vector.transpose %0, [1, 0] : vector<1x8xf32> to vector<8x1xf32>
%3 = vector.extract %2[0] : vector<1xf32> from vector<8x1xf32>
%4 = arith.addf %3, %1 : vector<1xf32>
%5 = vector.extract %2[1] : vector<1xf32> from vector<8x1xf32>
%6 = arith.addf %5, %4 : vector<1xf32>
... (repeats for all 8 elements) ...
%17 = vector.extract %2[7] : vector<1xf32> from vector<8x1xf32>
%18 = arith.addf %17, %16 : vector<1xf32>
%19 = vector.extract %18[0] : f32 from vector<1xf32>
return %19 : f32
}
```
* when lowering using the inner-reduction strategy, the compiler would
first unnecessarily transform it into a 2-D multi_reduction operation
<1x8xf32> and then extract an <8xf32> vector and apply reduction. The
canonicalization and folding would lead to the following final result:
```mlir
func.func @rank1_multi_reduction(%arg0: vector<8xf32>, %arg1: f32) -> f32 {
%0 = vector.reduction <add>, %arg0, %arg1 : vector<8xf32> into f32
return %0 : f32
}
```
Now, after this change:
* when lowering the compiler now produces for both strategies in one
step.
```
func.func @rank1_multi_reduction(%arg0: vector<8xf32>, %arg1: f32) -> f32 {
%0 = vector.reduction <add>, %arg0, %arg1 : vector<8xf32> into f32
return %0 : f32
}
```
This pattern is also useful for an ongoing refactoring that is happening
in the multi_reduction patterns. It is the only pattern that increases
multi_reduction in rank and would lead to an infinite loop when
attempting to reach a fixed point once we generalize other unrolling
patterns.

[clang][Modules] Fixing unexpected warnings triggered by a PCH and a module with config macros (#177078)
When a PCH is compiled with macro definitions on the command line, such
as `-DCONFIG1`, an unexpected warning can occur if the macro definitions
happen to belong to an imported module's config macros. The warning may
look like the following:
```
definition of configuration macro 'CONFIG1' has no effect on the import of 'Mod1'; pass '-DCONFIG1=...' on the command line to configure the module
```
while `-DCONFIG1` is clearly on the command line when `clang` compiles
the source that uses the PCH and the module.
The reason this can happen is a combination of two things:
1. The logic that checks for config macros is not aware of any command
line macros passed through the PCH
([here](https://github.com/llvm/llvm-project/blob/7976ac990000a58a7474269a3ca95e16aed8c35b/clang/lib/Frontend/CompilerInstance.cpp#L1562)).
2. `clang` _replaces_ the predefined macros on the command line with the
predefined macros from the PCH, which does not include any builtins
([here](https://github.com/llvm/llvm-project/blob/7976ac990000a58a7474269a3ca95e16aed8c35b/clang/lib/Frontend/CompilerInstance.cpp#L679)).
This PR teaches the preprocessor to recognize the command line macro
definitions passed transitively through the PCH, so that the error check
does not miss these definitions by mistake. The config macro itself
works fine, and it is only the error check that needs fixing.

Currently, `getOrder` returns null if the user does not provide an

utility functions that work on top of layouts (like `isTransposeOf`).
This PR introduce a `getEffectiveOrder` which always returns the true
order, even if user decides to omit it.

[lld][Hexagon] Fix findMaskR8 missing duplex support (#183936)
findMaskR8() lacked an isDuplex() check, unlike findMaskR6(),
findMaskR11(), and findMaskR16() which all handle duplex instructions.
When the assembler generates R_HEX_8_X on a duplex SA1_addi instruction
(e.g. `{ r0 = add(r0, ##target); memw(r1+#0) = r2 }`), the wrong mask
0x00001fe0 placed relocation bits at [12:5] instead of [25:20],
corrupting the low sub-instruction (e.g. memw became memb).
Add the isDuplex() check returning 0x03f00000, and add a comprehensive
test covering all duplex instruction x relocation type combinations
across findMaskR6, findMaskR8, findMaskR11, and findMaskR16.

Adds a Markdown generator that uses Mustache templates. This patch adds

allow for the creation of specific files needed by the MD tests like
`all-files.json`.
This backend should be considered experimental. It satisfies all the
same tests that the current MD backend is tested against, but those
don't seem to provide full coverage for all functionality inside that
backend. It also doesn't output everything provided by JSON. It doesn't
use the MD unittests because the Mustache templates must currently be
written to files.

Reverts llvm/llvm-project#125412
See the discussion in #125412 for why this is necessary. The summary is
that:
- Eliding arguments is the C23 extension, but libunwind builds its C
files with `-std=c99`, so this change broke the build.
- `-Wno-unused-parameter` is part of the build for libunwind, so the
codebase does allow them.

Previously misc-const-correctness warned about non-const unnamed

marking them as 'const' doesn't add additional information.
Also the diagnostic messages look awkward without a name.

different threads. For example, we allow dynamically loading plugins
from the command interpreter, which in theory could be coming from
different threads.

[652024,65535]. For pli.w, this is [4294966784,4294967295].
Since we're only inserting 16 or 32 bits, it makes sense to me that only
those 16 or 32 bits matter. This is similar to how we allow `li a0,
0xffffffff` on RV32.

[DebugInfo][DwarfDebug] Move emission of globals from beginModule() to endModule() (5/7) (#184219)
RFC
https://discourse.llvm.org/t/rfc-dwarfdebug-fix-and-improve-handling-imported-entities-types-and-static-local-in-subprogram-and-lexical-block-scopes/68544
This patch moves the emission of global variables from
`DwarfDebug::beginModule()` to `DwarfDebug::endModule()`.
It has the following effects:
1. The order of debug entities in the resulting DWARF changes.
2. Currently, if a DISubprogram requires emission of both concrete
out-of-line and inlined subprogram DIEs, and such a subprogram contains
a static local variable, the DIE for the variable is emitted into the
concrete out-of-line subprogram DIE. As a result, the variable is not
available in debugger when breaking at the inlined function instance.
It happens because static locals are emitted in
`DwarfDebug::beginModule()`, but abstract DIEs for functions that are
not completely inlined away are created only later during
`DwarfDebug::endFunctionImpl()` calls.
With this patch, DIEs for static local variables of subprograms that
have both inlined and the concrete out-of-line instances are placed into
abstract subprogram DIEs. They become visible in debugger when breaking
at concrete out-of-line and inlined function instances.
`llvm/test/DebugInfo/Generic/inlined-static-var.ll` illustrates that.
3. It will allow to simplify abstract subprogram DIEs creation by
reverting https://github.com/llvm/llvm-project/pull/159104 later.
This is needed to simplify DWARF emission in a context of proper support
of function-local static variables which comes in the next patch
(https://reviews.llvm.org/D144008), making all function-local entities
handled in `DwarfDebug::endModuleImpl()`.

This adds an ordering operand to atomic loads, stores, RMWs,
wait/notify,
and fences. It currently defaults to 0 and ISel is not updated yet, so
atomics produced by the compiler will still always be seqcst.
Asm parsing and printing, binary emission and disassembly are all
updated. Binary emission will always use the old encoding because the
encoding is smaller, and to get backwards compatibility for free.

[HLSL] groupshared variables should be implicitly extern and should not be initialized (#184459)
Makes groupshared variables have extern storage class which prevents
them from being initialized if no initializer is provided. If one is
provided as below:
```
groupshared uint A = 1;
```
A warning, which is an error by default, is produced that says the
initializer is ignored and the variable is NOT initialized.
Closes #183602

'eSymbolTypeInvalid', so any attempt to look at them fails. This fixes
that issue.

[dsymutil] Add option to filter debug map objects by allow/disallow-list (#182083)
# Motivation
When using `dsymutil` to generate dSYM for large binaries, sometimes we
want to keep only some of the object files. This has the benefits of
reduced dSYM size and improved performance of LLDB and other tools which
consume the dSYM.
The current way to achieve this is to use YAML input (the `dsymutil -y`
option). However, it doesn't really solve the problem:
1. The whole debug map has to be parsed somewhere else first, before
filtered down to the wanted parts.
2. Said info is written then read by `dsymutil`. The I/O is redundant.
# Change
This patch propose a new way, by adding new options (`dsymutil --allow
<path>` and `--disallow <path>`), which will only process object files
that pass the allow/disallow list.
Important details:
* The input file is YAML. See test files for format.
* Currently, only object files are filtered. The design allows to extend
the filtering to other aspects of the debug map in the future (e.g.
functions).
* If `--oso-prepend-path` is specified, it applies to the entries in the
input file. I.e. Entries in the input file should exact match that of
N_OSO entries.

[lld][WebAssembly] Convert weak-alias tests to assembly. NFC (#184667)
This actually both improves and simplifies the `Inputs/weak_alias`. With
the `.ll` version we ended up using memory and `__stack_pointer` and
locals, but LLVM ended up generated `call` rather than `call_indirect`
for the `call_alias_ptr` and `call_direct_ptr`. With the assembly tests
we can ensure the usage of `call_indirect` while avoiding all the other
stuff.

[CIR] Upstream global variable replacement (#184686)
This change upstreams the CIR implementation of global variable
replacement. When we get a call to get or create a global variable using
a type that does not match the previous type for a variable of the same
name, we need to replace the old definition with the new one. In classic
codegen that was as simple as replaceAllUses+eraseFromParent, but in CIR
because we have typed pointers, we need to visit the uses and update
them with bitcasts to reflect the new type.

deterministic ordering.

[Clang] Only define `wchar_size` module flag if non-standard (#184668)
Summary:
This PR simply changes the behavior of the `wchar_size` flag. Currently,
we emit this in all cases for all targets. This causes problems during
LLVM-IR linking, specifically because this would vary between Linux and
Windows in unintuitive ways. Now we have an llvm::Triple helper to
determine the size from the known values. The module flag will only be
emitted if these do not match (indicating a non-standard environment).
In addition to fixing AMDGCN bitcode linking, this also means we don't
need to bloat *every* IR module compiled by clang with this flag. The
changed tests reflects this, one less unnecessary piece of metadata.

On ppc64le, children are not produced for DW_TAG_subprogram "main" in

other platforms (AArch64/X86), DW_TAG_subprogram has DW_TAG_variable
"instance_C", which should not be matched by the check lines.
Loosened the check lines (turned CHECK-NEXT into CHECK) to make them
work for all mentioned platforms.

Model strings without any randomness marker characters (`%`), which
results in a unique path that's not at all unique. To avoid this
foot-gun, we now assert that the model contains at least one, and update
all the broken usages accordingly.

[lldb] Fix the AArch64 CPSR reg defn to list generic reg
My change to remove an incorrect DWARF register number for
CPSR unintentionally dropped the LLDB_REGNUM_GENERIC_FLAGS
generic reg type in the definitions of cpsr.
We need to have a macro (DEFINE_MISC_REGS) for status/control
registers that have no DWARF/eh_frame and no generic reg num.
I added a new macro, DEFINE_GPR_CPSR, for cpsr which is unique
in having no DWARF/eh_frame numbers but does have a generic
flags reg number.

[SafeStack] Fix crashing with scalable TypeSizes (#180547)
On e.g. aarch64 the TypeSize of scalar types can have a size that is not
known at compile time.
Currently when safestack occurs those it simply crashes as described in
https://github.com/llvm/llvm-project/issues/175868.
Since we cannot verify the size at compile time we simply consider the
access to be unsafe (in regards to safestack).
Reproducer:
```
#include <arm_sve.h>
int main() {
svint32_t vec = svindex_s32(0, 1);
svint32_t res = svadd_s32_z(svptrue_b32(), vec, vec);
int32_t buffer[1024];
svst1_s32(svptrue_b32(), buffer, res);
return 0;
}

[AMDGPU] Optimize S_SETREG_IMM32_B32 piggybacking by treating it as a mode scope boundary (#184703)
When `handleSetregMode` encounters an `S_SETREG_IMM32_B32` with `Size <=
12`, the instruction's `imm32[12:19]` bits are "free" for VGPR MSB
piggybacking. Previously, the old mode was eagerly written into these
bits, but the `Rewritten` guard in `setMode` would then block subsequent
piggybacking when the next VGPR instruction needed a different mode,
causing an unnecessary `S_SET_VGPR_MSB` to be emitted.
Model the `S_SETREG_IMM32_B32` as the boundary of the old mode's control
range: reset `CurrentMode` and clear `bits[12:19]` to zero. This lets
the next `setMode` call freely piggyback the required mode without
triggering `Rewritten`.

[MLIR][Vector] Fix crash in operatesOnSuperVectorsOf on rank-mismatched shaped (#183967)
The `operatesOnSuperVectorsOf` function in VectorUtils.cpp contained an
assertion that fired when a `vector.transfer` operation's vector type
had a different rank (or non-divisible shape) from the sub-vector type
supplied by the caller:
assert((ratio || \!mustDivide) &&
"vector.transfer operation in which super-vector size is not an"
" integer multiple of sub-vector size");
This assertion was incorrect because the function's callers (e.g., the
affine super-vectorizer) legitimately pass transfer ops whose vector
type doesn't match the requested sub-vector shape. In those cases the
correct answer is simply that the op does not operate on a super-vector
of that sub-vector type, so `operatesOnSuperVectorsOf` should return
`false`.
Remove the assert return `false` when `computeShapeRatio` produces no
result, and remove the now-unused `mustDivide` variable.

Detect IR where result types, operand types, or discardable attribute

Mixing contexts is a latent use-after-free hazard when one context is
destroyed before the other; the verifier now reports a clear error
instead of silently allowing the invalid IR through.
Three new unit tests in MLIRIRTests cover each scenario.

[mlir][spirv] Fix crash in FuncOpVectorUnroll for dynamic-shaped tensor args (#184626)
FuncOpVectorUnroll::matchAndRewrite iterates over all function arguments
and creates a zero-constant placeholder for any non-vector argument via
rewriter.getZeroAttr(type). For dynamically-shaped tensor types such as
tensor<?x2xi8>, getZeroAttr ultimately calls
DenseIntOrFPElementsAttr::getRaw which asserts that the type has a
static shape.
Add an early pre-check that returns failure() for any non-vector
argument with a dynamically-shaped type. This must be done before any IR
modifications are made, since returning failure() after inlining the
function body would leave the IR in an inconsistent state.

[flang-rt] Fixes EXECUTE_COMMAND_LINE() status management and double buffering (#184285)
EXECUTE_COMMAND_LINE() without CMDSTAT initiated termination in runtime
if the command returned non-zero status code. For example,
EXECUTE_COMMAND_LINE('false') on Linux would cause "fatal Fortran
runtime error... : Command line execution failed with exit code: 1."
This is too strict: EXECUTE_COMMAND_LINE() successfully called 'false',
it's just 'false' happened to return non-zero status code. ifx and
gfortran don't initiate termination in such case. Changed
EXECUTE_COMMAND_LINE() implementation to behave in similar fashion.
Also during testing discovered that when the output of the program that
uses EXECUTE_COMMAND_LINE(... WAIT=.false.) is piped to a file, the
resulting file has duplicated output lines. This was because fork()
command also ends up duplicating parent's buffered output to the child.
Added flush of all units and C stdio before calling fork().

Intended to be NFC but it looks like in
test/CodeGen/RISCV/rvv/fixed-vectors-insert-subvector-shuffle.ll we were
previously reducing the vl of a volatile load in
insert_subvector_dag_loop, which RISCVVLOptimizer knows to avoid.

[clangd][NFC] Add RefKind::Call into RefKind::All and insertion operator (#184677)
Without this patch:
- RefKind output doesn't show RefKind::Call bit.
- RefKind::Call isn't included in RefKind::All.
I don't think these changes require additional tests, as the problems
above mainly appear during testing/debugging (e.g. if in tests
comparison of two RefKinds fails, `Call` isn't shown in the output even
if this bit is set).

[mlir][MemRef] Add position-based matching heuristics for rank-reduction with dynamic strides (#184334)
When multiple source dimensions have multiple unit dimensions,
stride-based disambiguation can be wrong with dynamic strides. Add
position-based matching: for each result dimension in order, pick the
leftmost unmatched source dimension with the same size; unmatched source
dims are dropped.
Example: subview from memref<1x8x1x3> to memref<1x8x3>. Both dim 0 and
dim 2 have size 1. Stride-based logic cannot distinguish when strides
are dynamic. Position-based matching correctly drops dim 2 (middle unit
dim) instead of dim 0.
When we have non-trivial static strides, we make use of the stride-based
logic, else we fall back to position-based logic as introduced by this
patch.
INPUT :-
```
func.func @fold_rank_reducing_subview_1x8x1x3_to_1x8x3_drop_middle_unit_dim(
%arg0 : memref<?x?x?x?xf32, strided<[?, ?, ?, ?], offset: ?>>,
%arg1 : index, %arg2 : index, %arg3 : index, %arg4 : index) -> f32 {
%c0 = arith.constant 0 : index
%0 = memref.subview %arg0[0, 0, 0, 0][1, 8, 1, 3][1, 1, 1, 1]

return %1 : f32

WITHOUT this patch we get :-

[MLIR][NVVM] Unify and move to a single tcgen05_mma_kind attr for all tcgen05.mma Ops (#184433)
This change unifies using of `tcgen05_mma_kind` attribute for
tcgen05.mma Ops in MLIR.
Before this change there were two block scale attributes used for
tcgen05.mma Ops. One was `MMABlockScaleKindAttr` with `mxf8f6f4`, `mxf4`
and `fxf4nvf4` values used for `tcgen05.mma.block_scale` and
`tcgen05.mma.sp.block_scale`. Another one was `Tcgen05MMAKindAttr` with
`f16`, `tf32`, `f8f6f4` and `i8` values used for `tcgen05.mma`,
`tcgen05.mma.sp`, `tcgen05.mma.ws` and `tcgen05.mma.ws.sp`.
`Tcgen05MMAKindAttr` has been extended with values from
`MMABlockScaleKindAttr`. Now there is `tcgen05_mma_kind` attribute only
for all `tcgen05.mma` Ops in MLIR.
Backward compatibility is not supported. Existing tests and scripts
should be updated to use `tcgen05_mma_kind` attribute instead of
`block_scale_kind` for all tcgen05.mma MLIR Ops.

[SystemZ] Mark fminimumnum/fmaximumnum as legal (#184595)
In M=4 mode, the behavior matches IEEE 754-2019 minimumNumber, except
that if both operands are sNaN, the result will be sNaN rather than
qNaN. However, this is explicitly allowed for LLVM's minimumnum
intrinsic, as canonicalization can be omitted for non-constrainted FP.
As such, mark fminimumnum/fmaximumnum as legal, and lower them the same
way as fminnum/fmaxnum. In the future, we may wish to switch those to
use M=0 instead, to match IEEE 754-2008 maxNum/minNum instead.

[VPlan] Move tail folding out of VPlanPredicator. NFC (#176143)
Currently the logic for introducing a header mask and predicating the
vector loop region is done inside introduceMasksAndLinearize.
This splits the tail folding part out into an individual VPlan transform
so that VPlanPredicator.cpp doesn't need to worry about tail folding,
which seemed to be a temporary measure according to a comment in
VPlanTransforms.h.
To perform tail folding independently, this splits the "body" of the
vector loop region between the phis in the header and the branch + iv
increment in the latch:
Before:
```
+-------------------------------------------+
|%iv = ... |
|... |
|%iv.next = add %iv, vfxuf |
|branch-on-count %iv.next, vector-trip-count|
+-------------------------------------------+
```
After:
```
+-------------------------------------------+
|%iv = ... |
|%wide.iv = widen-canonical-iv ... |
|%header-mask = icmp ule %wide.iv, BTC |---+
|branch-on-cond %header-mask | |
+-------------------------------------------+ |
| |
v |
+-------------------------------------------+ |
|... | |
+-------------------------------------------+ |
| |
v |
+-------------------------------------------+ |
|%iv.next = add %iv, vfxuf |<--+
|branch-on-count %iv.next, vector-trip-count|
+-------------------------------------------+
```
Phis are then inserted in the latch for any value in the loop body that
have outside uses, with poison as their incoming value from the header
edge.
The motivation for this is to allow us to share the same "predicate all
successor blocks" type of predication we do for tail folding, but for
early-exit loops in #172454. This may also allow us to directly emit an
EVL based header mask, instead of having to match + transform the
existing header mask in addExplicitVectorLength.
This also allows us to eventually handle recurrences in the same
transform, avoiding the need to special case tail folding in
addReductionResultComputation.

[AArch64] Fix SVE cost model for various math intrinsics (#184358)
The implementation of getIntrinsicInstrCost in BasicTTIImpl
assumes that for some intrinsics if we're using custom
lowering for the equivalent DAG node that the cost needs to
be 2, instead of 1 for legal ops. However, even though we
use custom lowering for these scalable vector operations
when SVE is available, we still end up generating the same
efficient codegen as fixed-width. This patch deals with a
few obvious intrinsics that we know get lowered to something
sensible and return the same cost as NEON, i.e. 1.

[AArch64] Fold zero-high vector inserts in MI peephole optimisation (#182835)
Summary
This patch follows on from #178227.
The previous ISel fold lowers the 64-bit case to:
```
fmov d0, x0
fmov d0, d0
```
which is not ideal and could be fmov d0, x0.
A redundant copy comes from the INSERT_SUBREG/INSvi64lane.
This peephole detects <2 x i64> vectors made of a zeroed upper and low
lane produced by FMOVXDr/FMOVDr, then removes the redundant copy.
Further updated tests and added MIR tests.

[mlir][sparse] Fix crash in SparseAssembler when run after SparseTensorCodegen (#183896)
After --sparse-tensor-codegen, sparse tensor arguments are replaced by
memrefs and \!sparse_tensor.storage_specifier types. The subsequent
--sparse-assembler pass calls getSparseTensorEncoding() to identify
sparse arguments to wrap/unwrap. However, getSparseTensorEncoding()
returns non-null for StorageSpecifierType as well as for sparse
RankedTensorType. Since StorageSpecifierType is not a RankedTensorType,
the subsequent cast<RankedTensorType> in convTypes() and convVals()
would crash with an assertion failure.
Fix by also checking isa<RankedTensorType>(type) in the passthrough
condition in both convTypes() and convVals(), so that
StorageSpecifierType arguments pass through unchanged.

[mlir][sparse] Fix crash in sparsification when unary/binary present block captures sparse tensor argument (#184597)
`relinkBranch` in Sparsification.cpp assumed that any block argument
from the outer `linalg.generic` op encountered inside an inlined
semi-ring branch must be a dense tensor, and asserted accordingly.
However, the `present` block of a `sparse_tensor.unary` (or similar
semi-ring ops) is permitted to capture sparse tensor operands directly
via `isAdmissibleBranchExp`, which accepts any `BlockArgument` as
admissible.
The fix removes the incorrect assertion and extends the load generation
to handle sparse tensors using `genSubscript`, which already knows how
to return the value buffer and current value position via the loop
emitter. The `kSparseIterator` strategy (where `genSubscript` returns a
`TensorType`) is also handled by emitting a
`sparse_tensor.extract_value` op.

[mlir][bytecode] Fix crash when reading DenseIntOrFPElementsAttr with unsupported element type (#184773)
When a bytecode type callback substitutes a type that does not implement
DenseElementTypeInterface (e.g., \!test.i32 replacing i32), the bytecode
reader attempted to reconstruct a DenseIntOrFPElementsAttr with that
type. This unconditionally called getDenseElementBitWidth() which hit an
llvm_unreachable on unsupported types.
Fix this by validating the element type implements
DenseElementTypeInterface in readDenseIntOrFPElementsAttr before
proceeding. If the check fails, a proper diagnostic is emitted and
reading fails gracefully instead of crashing.

BroadcastOp::fold used an unchecked llvm::cast<DenseIntElementsAttr> on

against a missing (unset) attribute, not against a non-null attribute of
a different type such as PoisonAttr (produced when an operand is
ub.poison).
Replace the unchecked casts with dyn_cast_or_null, bailing out with
nullptr (i.e. no fold) when any operand does not provide a
DenseIntElementsAttr.
Add a regression test with a ub.poison operand.

[mlir][bufferization] Fix use-after-free in ownership-based buffer deallocation (#184118)
When `handleInterface(RegionBranchOpInterface)` processes an op such as
`scf.for`, it calls `appendOpResults` to clone the op with extra
ownership result types and erase the original. The `Liveness` analysis
is computed once before the transformation begins and may still
reference the old (now-freed) result values.
If the same block contains a `BranchOpInterface` terminator (e.g.,
`cf.br`) after the structured loop, `handleInterface(BranchOpInterface)`
calls `getMemrefsToRetain`, which iterates `liveness.getLiveOut()`. That
set may contain stale `Value` objects pointing to the erased op's
results. Calling `isMemref()` on such a value dereferences freed memory,
triggering a crash.
Fix by adding a `valueMapping` map to `DeallocationState`. Before
erasing the old op in `handleInterface(RegionBranchOpInterface)`, record
the old-to-new result mapping via `state.mapValue`. The
`getLiveMemrefsIn` and `getMemrefsToRetain` helpers translate stale
liveness values through this map before calling `isMemref`, so they
always operate on live pointers.

[VPlan] Replicate VPScalarIVStepsRecipe by VF outside replicate regions. (#170053)
Extend replicateByVF to also handle VPScalarIVStepsRecipe. To do so, the
patch adds a new lane operand to VPScalarIVStepsRecipe, which is only
added when replicating. This enables removing a number of lane 0
computations. The lane operand will also be used to explicitly replicate
replicate regions in a follow-up.

[flang][OpenMP] Fix crash when a sliced array is specified in a forall within a workshare construct (#170913)
This is a fix for two problems that caused a crash:
1. Thread-local variables sometimes are required to be parallelized.
Added a special case to handle this in
`LowerWorkshare.cpp:isSafeToParallelize`.
2. Race condition caused by a `nowait` added to the `omp.workshare` if
it is the last operation in a block. This allowed multiple threads to
execute the `omp.workshare` region concurrently. Since
_FortranAPushValue modifies a shared stack, this concurrent access
causes a crash. Disable the addition of `nowait` and rely on the
implicit barrier at the the of the `omp.workshare` region.

This patch adds typeid lowering, which uses a lot of the infrastructure
from dynamic_cast. However, this adds a `get_type_info` operation that
gets the type info out of a vtable pointer as well, which lets the
offset be handled by the ABI specific lowering code.

[mlir][CFGToSCF] Fix crash when encountering unknown control flow ops (#184103)
When transformToStructuredCFBranches encountered a control flow op not
handled by the CFGToSCFInterface (e.g., spirv.BranchConditional with
--lift-cf-to-scf), it correctly emitted an error and returned failure.
However, blocks had already been moved from the parent region into
temporary local Region objects before the failure was detected.
When those temporary Region objects went out of scope, their destructor
tried to destroy the contained blocks. But those blocks still had live
predecessor references from the parent region (the regionEntry's
terminator still pointed to them), causing an assertion failure:
use_empty() && "Cannot destroy a value that still has uses\!"
Fix: on failure from createStructuredBranchRegionOp, move the blocks
from the temporary conditionalRegions back into the parent region before
returning failure. This restores IR consistency and allows the Region
destructor to run safely.
Fixes #120883
Fixes #118454

[CIR] Fix void ternary operators- (#184691)
I discovered this while working on something else, but we were doing a
'getTerminator' on a block that we didn't know whether it had a
terminator, and MLIR causes an assert in this case. This patch
re-factors the code to better check whether it might have a terminator
(to assuage the assert in mlir::Block), and get the correct value out.
The fixup later in the ternary setup correctly gets the 'void' yields
correct, so everything else gets fixed eventually.

This is necessary to support build environments where the

this, we try and resolve binaries relative to the real path of
clang-linker-wrapper, which is usually in a directory prefixed with the
first couple characters of a SHA digest and named with a SHA digest. We
also need to ensure that we propagate --no-canonical-prefixes to sub
clang invocations so that clang is able to resolve lld in such
environments.

[Flang][OpenMP] Skip intermediate map generation for motion modifier map directives (#177737)
Currently if we create the following map:
!$omp target update from/to(derived_type%allocatable)
We'll generate an extra map for the derived type (and any other
allocatable maps that may be in-between the final mapped allocatable
member). However, for cases like this, and other motion modifier related
map directives we don't need to do so. All the user cares about is the
specified member. Removing the intermediate member will minimize extra
performance overhead. It also maintains correctness, as currently, the
MLIR diagnostics for the motion modifiers restricts possible map types
for updates to to and from, and applying this map type to an
intermediate map will result in unintended side affects, e.g. mapping
back data the user didn't want to or over-writing data they didn't
intend to on device. This minor modification addresses that.

COFF: Allow hex literals in .def files: BASE/HEAPSIZE/STACKSIZE (#184764)
For a Win32 DLL, a .def file can have a custom executable base:
```
LIBRARY "stub.dll" BASE=0x10000000
```
Currently the parser enforces Base 10, but [Microsoft's
documentation](https://learn.microsoft.com/en-us/cpp/build/reference/rules-for-module-definition-statements?view=msvc-170)
states "Numeric arguments are specified in base 10 or hexadecimal".
This fixes that, and also HEAPSIZE and STACKSIZE (which use the same
function).
There are a few more instances of `getAsInteger` that expect base10 -
for ordinals and the VERSION directive. Since I don't have an
in-the-wild example of a .def file using hexadecimal for these, I am
wary about changing those too.

Currently with `-DLLVM_DISTRIBUTION_COMPONENTS="flang-fortran-binding"`,
header file `ISO_Fortran_binding.h` is only installed at
`./lib/clang/23/include/ISO_Fortran_binding.h`, but not in the user
include.
This PR is to fix that so that the `ISO_Fortran_binding.h` is also
installed at `./include/flang/ISO_Fortran_binding.h`, which is the same
as the "normal" (non-distribution) build.

[mlir][memref] Fix crash in DimOp::fold for subview with ambiguous dropped dims (#183995)
When a rank-reducing subview has multiple size-1 source dimensions and
all strides are dynamic, `computeMemRefRankReductionMask` cannot
unambiguously determine which dimension is dropped. It would fall back
to an arbitrary choice that could be wrong.
In `DimOp::fold`, the code then maps a result dimension to that
(possibly incorrect) source dimension and asserts
`isDynamicSize(sourceIndex)`. If `getDroppedDims()` picked the wrong
dropped dim, the source dim at `sourceIndex` may be statically sized,
causing the assertion to fire.
Fix this by replacing the assert with a guard that returns `{}` (no
fold) when the resolved source dimension is not dynamic. This is safe
because the fold already handles the statically-sized result case
earlier.
Fixes #111244

[MLIR][XeGPU] Decompose unsupported 'vector.transfer_read'-transpose-permutations (#182875)
The PR adds a pattern to `vector-to-xegpu` pass that decomposes
`vector.transfer_read` with unsupported transpose-permutations
(unsupported element-type) into `vector.transfer_read +
vector.transpose`:
Example:
```mlir
// input-ir:
%0 = vector.transfer_read %source[%offset, %offset], %c0
{permutation_map = affine_map<(d0, d1) -> (d1, d0)>,
in_bounds = [true, true]} : memref<32x64xf16>, vector<8x16xf16>
// mlir-opt %s --convert-vector-to-xegpu
// before PR (no conversion because of unsupported type):
%0 = vector.transfer_read %source[%offset, %offset], %c0
{permutation_map = affine_map<(d0, d1) -> (d1, d0)>,
in_bounds = [true, true]} : memref<32x64xf16>, vector<8x16xf16>
// mlir-opt %s --convert-vector-to-xegpu
// after PR (decomposed + converted):
%0 = xegpu.load_nd %source[%offset, %offset]
%1 = vector.transpose %0
```

[MLIR][XeGPU] Support vector.contract transpose_a/transpose_b via 'vector-to-gpu' patterns (#182885)
The PR adds [`vector.contract(transpose_a/transpose_b)` decomposition

The `populatePrepareVectorToMMAPatterns` adds two patterns:
1. `PrepareContractToGPUMMA` that splits `vector.contract(transpose)`
into `vector.transpose + vector.contract`
2. `CombineTransferReadOpTranspose` that fuses `vector.transpose` into
the permutation map of `vector.transfer_read`
The second pattern doesn't always bring us to the desired result
(`xegpu.load_nd + vector.transpose + xegpu.dpas`) since [not all data
types are supported

for the transposed-read case. There's a second PR (#182875) on this
matter that adds a decomposition-pattern for unsupported types (it might
seem strange that we first fuse and then decompose
transfer_read+transpose but this way we don't have code duplication
between vector-to-gpu&to-xegpu passes and cover all functional cases)

Add the ability to "allow another thread to see the private state" mode. (#184272)
When lldb stops to run a breakpoint condition or other callback that has
to happen between the private stop and returning control to the user, it
will run in the state where the public state is still "running". But if
the callback needs to run lldb commands or python code, it needs to see
the correct "stop" state.
We used to handle that by switching the public state to stopped before
running the callbacks. However, that opened a window where we are still
handling the stop event and another thread would be allowed to continue
the target or do other actions that can interfere with that orderly
process.
This patch adds the ability to designate a particular thread as "seeing
the private state" while all other threads see the "public state". Then
when we run a breakpoint callback, no threads but the one that is
actually running the callback will see the state change until the event
has been delivered to the primary state listener.
It also adds a test that while a long-running breakpoint callback runs,
another thread continues to see the state as running.

The two-tier relaxation hook design (fixupNeedsRelaxationAdvanced
delegating to fixupNeedsRelaxation) is confusing and unnecessary.
Only M68k and AMDGPU used fixupNeedsRelaxation (via the default
fixupNeedsRelaxationAdvanced). AArch64 and CSKY had dead overrides:
they don't override mayNeedRelaxation to ever return true.
Merge the two hooks: convert M68k and AMDGPU to override
fixupNeedsRelaxationAdvanced directly, remove dead overrides from
AArch64 and CSKY, and simplify the default implementation to
`return !Resolved`.

[SelectionDAG] Fix cycle in ReplacedValues during type legalization (#184697)
During type legalization, `ReplaceValueWith` handles morphed nodes by
computing `OldValId` and `NewValId`, calling `ReplaceAllUsesOfValueWith`
(RAUW), then adding `ReplacedValues[OldValId] = NewValId`.
However, the RAUW call can trigger `CSE`, which fires NoteDeletion
callbacks that add new entries to `ReplacedValues`. If NoteDeletion adds
`ReplacedValues[A] = B`, and the subsequent assignment adds
`ReplacedValues[B] = A`, a cycle is created. RemapId then recurses
infinitely following the cycle during path compression, causing a stack
overflow crash.
On AArch64, i16 is not a legal type and requires promotion to i32. When
IR uses i16 values as `extractelement` indices that feed into other
`extractelement` operations, the interplay between result promotion and
operand promotion creates the specific CSE pattern that produces the
cycle.
Fix by calling RemapId on both OldValId and NewValId after the RAUW call
to account for new ReplacedValues entries added during the RAUW cascade.
In the reproducer, this causes both ids to resolve to the same value,
skipping the assignment and preventing the cycle.

[HLSL][Matrix] Add APValue and ConstExpr evaluator support for matrices (#178762)
Fixes #168935
This PR adds basic support for matrix APValues and a ConstExpr evaluator
for matrices.
- ConstExpr evaluation changes:
- Matrix initializer list
- Matrix HLSL elementwise cast
- Matrix HLSL aggregate splat
- Vector HLSL matrix truncation
- Int HLSL matrix truncation
- Float HLSL matrix truncation
- Matrix APValue:
- AST dumper and serialization
- Value flattening
Note that APValue matrices hold its elements in row-major order
irrespective of the `-fmatrix-memory-layout` flag.
The `-fmatrix-memory-layout` is for codegen, not semantics, so the
decision of which memory layout to use for the matrix APValue can be
independent of the memory layout for codegen.
There are also a number of places expecting switch case coverage over
all APValues but which do not currently support matrix APValues. I have
added placeholder llvm_unreachables to these places for the matrix
APValue, as these places can not currently be exercised in clang tests
(AFAIK).

[clang][deps] Simplify by-module-name scan API (#184376)
The by-module-name scanning APIs are fairly spread out. There's the main
`CompilerInstanceWithContext` class that provides a constructor,
`initialize()` and `computeDependencies()`. Then there's the
`DependencyScanningWorker` that optionally owns
`CompilerInstanceWithContext` and re-exposes two `initialize()` and one
`computeDependencies()` functions. Lastly, there's
`DependencyScanningTool` that again re-exposes two variants of
`initialize()` and one `computeDependencies()`.
The current setup makes it unnecessarily difficult to make changes to
these APIs (as observed in
https://github.com/swiftlang/llvm-project/pull/12453).
This PR makes `CompilerInstanceWithContext` standalone, and hides the
construct + initialize pattern behind a static factory function. This
makes it harder to misuse the API (forgetting to call `initialize()`,
calling it twice, etc.) and means changes now need to only touch single
class instead of three classes spread over multiple files.

[libc] Rework slab cache data structure for GPU allocator
Summary:
This was previously a Trieber stack, which is a perfectly fine generic
and lock-free data structure. However, this used some expensive CAS
operations and had issues with ABA. Because the only user of this was
the slab cache mechanism, we can pretty safely specialize it. Instead,
we simply search a fixed size buffer for some sentinal values and CAS
into it.
For allocations that only ever hit the cache, this improves performance
from ~9000 cycles to ~6000 cycles and similar improvements for workloads
that feel the pain of small thread counts hitting the cache.

Summary:
This implementation only worked if the lane mask passed in was uniform,
but this is against the expected usage where the user may be wishing to
check if a value is uniform *within* a mask subset. Also remove
redundant sync_lanes, the ballots and shuffles already have
synchronizing behavior.

[clang][bytecode][HLSL][Matrix] Support `ConstantMatrixType` and more HLSL casts in the new constant interpreter for basic matrix constexpr evaluation in HLSL (#184840)
Forgot to change the target branch before merging. This PR is a
cherry-pick of the squashed-and-merged PR commit
b16aa4b7ec665911c74300cd7442659b70973d13 from 183424
This PR fixes #182963
This PR is an extension of #178762 which has already been merged.
This PR adds support for `ConstantMatrixType` and the HLSL casts
`CK_HLSLArrayRValue`, `CK_HLSLMatrixTruncation`,
`CK_HLSLAggregateSplatCast`, and `CK_HLSLElementwiseCast` to the
bytecode constexpr evaluator.
The implementations of CK_HLSLAggregateSplatCast and
CK_HLSLElementwiseCast are incomplete, as they still need to support
struct and array types to enable use of the experimental new constant
interpreter on other existing HLSL constexpr tests. The completion of
the implementations of these casts will be tracked in a separate issue
(#183426) and implemented in a separate PR.

[flang][OpenMP] Utilities to get uppercase directive/clause names (#184853)
It is a convention to use uppercase names of directives and clauses in
diagnostic messages, but getting such names is somewhat cumbersome:
```
parser::ToUpperCaseLetters(llvm::omp::getOpenMPDirectiveName(dirId));
parser::ToUpperCaseLetters(llvm::omp::getOpenMPClauseName(clauseId));
```
Implement `GetUpperName` (overloaded for clauses and directives) to
shorten it to
```
GetUpperName(dirId, version);
GetUpperName(clauseId, version);
```
This patch replaces existing instances of this pattern, adding the use
of OpenMP version where it was previously missing.

The commit adds implicit conversion warnings for HLSL matrix types in
Clang's semantic checker by extending SemaChecking.cpp to detect
precision loss when converting between matrix types (specifically,
ConstantMatrixType).
A new test validates float precision warnings, and an existing test was
updated to expect the new diagnostics.

[clang][modules] Add warning for module maps with ".." paths (#184279)
Implicitly discovered module maps that reference files outside their
module directory cause order dependent behavior when using implicitly
discovered module maps. This adds an off by default diagnostic about
these cases with the long term goal of removing import order dependent
behavior.
Module maps found via `-fmodule-map-file=` are not a problem because
they are all loaded at the start of translation.

This patch seems to cause TestWatchpointCommandPython.py to time out
on the ubuntu buildbots (but nowhere else that I can find so far.) The
timeout is weird too, the TEST FILE is timing out but the individual
tests aren't being shown and there's no other output. Grrr...
Anyway I'll revert this and then see if I can do some guessing about
how this change might cause the test to fail.

We only support splat shift amounts. Previously we checked if the shift

I don't think there is a guarantee that the splat_vector will stick
around as a splat_vector. It's safer if we capture the splat and create
a dedicated node with a scalar shift amount.

This reverts commit 7ad2c6db54a0e77249f2edb3c589ccf4c930d455.
PR #183395 introduced the `exact` flag to `index_cast` and
`index_castui` and updated some canonicalization patterns.
These canonicalization patterns were found to be unsound. For example:
* `index_cast(index_cast(x)) -> x`
* where one first truncates and then widens x
the rewrite is unsound because information is lost on the first cast as
it **may** truncate the value of x, therefore losing information. The
`exact` flag was made to make this transformation sound. Its semantics
are that when the `exact` flag is present, then it is assumed that the
operand to index_cast does not lose information (i.e., fits perfectly in
the destination type).
In PR #183395, the canonicalization rule was rewritten such that would
only match where the inner index_cast had the `exact` flag set.
* `index_cast(index_cast(x, exact)) -> x`
* where source type and destination type are the same
A post-merge review
[highlighted](https://github.com/llvm/llvm-project/pull/183395#discussion_r2880422529)
that the pattern above also disallows the following correct pattern:
* `index_cast(index_cast(x)) -> x`
* when the first index widens and the second one truncates.
Unfortunately the semantics of `index` are such that its bitwidth is
target specific. Attempts were made in
https://github.com/llvm/llvm-project/pull/184631 to automatically add
annotations were possible but no agreement was reached on the best way
to do this. Adding to the disagreement are the following points:
* [there are other unsound patterns that assume index is
64](https://github.com/llvm/llvm-project/pull/184631/changes#r2885181291)
* [The semantics of index is
contested](https://discourse.llvm.org/t/index-type-and-assumption-about-bitwidth/88287)
This lead to the belief that a reversal and an RFC would be a good
approach to get some consensus from the community before proceeding
further.

[mlir][acc] Add acc.compute_region and acc.par_width operations (#184864)
Introduce two new codegen operations to the acc dialect that model GPU
compute region execution and parallel launch configuration:
- acc.par_width: specifies a parallel dimension.
- acc.compute_region: wraps a region of code for GPU execution,
capturing
launch configuration (from acc.par_width results) and input values as
block arguments.
These operations bridge the gap between high-level OpenACC compute
constructs (acc.parallel, acc.kernels, acc.serial) and gpu.launch. The
passes that do these transformations will soon follow.

[Clang][CIR][AArch64] NFC: Cleanups in AArch64 builtins lowering (#184404)
This patch performs small cleanups and fixes in the AArch64 builtins
lowering code, with the goal of aligning the CIR path more closely
with the existing Clang CodeGen implementation.
Changes include:
* Make sure that `noundef` is consistently matched using `{{.*}}`.
* Rename `AArch64BuiltinInfo` to `armVectorIntrinsicInfo` for better
consistency with the original CodeGen implementation.
* Simplify `emitAArch64CompareBuiltinExpr`, fix an incorrect
assert condition (missing `!`) and make sure to use the input `kind`
condition instead of hard-coding `cir::CmpOpKind::eq`.
* Improve and clarify comments.
No functional changes intended (NFC).

[flang][acc] Handle ViewLike ops with OutlineRematerializationOpInterface in OffloadLiveInValueCanonicalization (#184218)
`fir::ConvertOp` implements both `ViewLikeOpInterface` and
`OutlineRematerializationOpInterface`. `fir.convert` is also used for
ptr-to-int conversions like `(!fir.ref<i32>) -> i64`. That is not really
a "view" — it converts a pointer to an integer — but
`ViewLikeOpInterface` is still attached, so `getOriginalValue` traces
through it to the underlying value.
When the underlying value is not a rematerialization candidate (e.g.,
`fir.alloca`, a block argument, or a `fir.call` result),
`isRematerializationCandidate` returns false and the `fir.convert` is
left as a live-in. This prevents `ACCImplicitData` from tracing back to
the original pointer to create the data mapping.
This PR:
1. Registers `fir::ConvertOp` with
`OutlineRematerializationOpInterface`.
2. Adds a fallback in `isRematerializationCandidate`: when the traced
original op is not a candidate, check the direct defining op (the
`fir.convert` itself) for `OutlineRematerializationOpInterface`.
```fortran
subroutine test()
integer :: x
!$acc declare create(x)
!$acc parallel
x = 1
!$acc end parallel
end subroutine
```
Before: CSE merges `fir.convert` outside the region; `ACCImplicitData`
cannot map the pointer.
After: `fir.convert` is sunk/rematerialized inside the ACC region
regardless of its input source.

[CIR][AArch64] Add missing lowerings for vceqz_* Neon builtins (#184893)
Implement the remaining CIR lowerings for the AdvSIMD (Neon)
`vceqz{|q|d|s}_*` intrinsic group (bitwise equal to zero).
The `vceqzd_s64` variant was already supported; this patch completes
the rest of the group [1].
Tests for these intrinsics are moved from:
* test/CodeGen/AArch64/neon-misc.c
to:
* test/CodeGen/AArch64/neon/intrinsics.c
The implementation largely mirrors the existing lowering in
CodeGen/TargetBuiltins/ARM.cpp.
`emitCommonNeonBuiltinExpr` is introduced to support these lowerings.
`getNeonType` is moved without functional changes.

[lldb] Automatic indexing for synthetic children of collections (#174885)
Synthetic providers for collection types use a child name format of
"[N]".
This `ValueObjectSynthetic` to automatically convert child names in this
convention to the index embedded in the subscript string. With this
change, synthetic formatters for collections will only need to implement
`GetIndexOfChildWithName` or `get_child_index` for non-indexed
collection children. Some examples of non-indexed children are
`$$dereference$$` support, or "hidden" children.
The automatic conversion applies to N values that are less than the
number of children reported by the synthetic provider.

The target implementations are already provided by

so targets were unnecessarily duplicating these.
This also fixes the default scope, which should be
memory_work_group_scope. Previously this was guessing that
if the flags included global memory, it makes the scope
device which is not the case.

[clang][modules] -Wmodule-import-in-extern-c should not be an error by default (#184530)
Importing a module inside of an `extern "C" {...}` section doesn't have
any effect, i.e. the imported module is not treated as `extern "C"`,
it's built independent of the includer state. The warning is akin to
`-Wconfig-macros`, it's trying to say that the behavior will be
different (and unexpected) when compiling with modules. That doesn't
need to be an error, a warning is enough. As an error, it makes it
difficult to support and test modules in C++ mode while dependencies
still have includes in `extern "C" {...}`.

[SYCL] SYCL host kernel launch support for the sycl_kernel_entry_point attribute. (#152403)
The `sycl_kernel_entry_point` attribute facilitates the generation of an
offload kernel entry point function based on the parameters and body
of the attributed function. This change extends the behavior of that
attribute to support integration with a SYCL runtime library through
an interface that communicates symbol names and kernel arguments
for the generated offload kernel entry point functions.
Consider the following function declared with the
`sycl_kernel_entry_point` attribute with a call to this function
occurring in the implementation of a SYCL kernel invocation function
such as `sycl::handler::single_task()`.
```c++
template<typename KernelName, typename KernelType>
[[clang::sycl_kernel_entry_point(KernelName)]]
void kernel_entry_point(KernelType kernel) {
kernel();
}
```
The body of the above function specifies the parameters and body of the
generated offload kernel entry point. Clearly, a call to the above
function by a SYCL kernel invocation function is not intended to execute
the body as written. Previously, code generation emitted an empty
function body so that calls to the function had no effect other than to
trigger the generation of the offload kernel entry point. The function
body is therefore available to hook for SYCL library support and is now
substituted with a call to a (SYCL library provided) function template
or variable template named `sycl_kernel_launch()` with the kernel
name type passed as the first template argument, the symbol name
of the offload kernel entry point passed as a string literal for the first
function argument, and the function parameters passed as the
remaining explicit function arguments. Given a call like this:
```c++
kernel_entry_point<struct KN>([]{})
```
the body of the instantiated `kernel_entry_point()` specialization would
be substituted as follows with "kernel-symbol-name" substituted for the
generated symbol name and `kernel` forwarded.
```c++
sycl_kernel_launch<KN>("kernel-symbol-name", kernel)
```
Name lookup and overload resolution for the `sycl_kernel_launch()`
function is performed at the point of definition of the
`sycl_kernel_entry_point` attributed function (or the point of
instantiation for an instantiated function template specialization). If
overload resolution fails, the program is ill-formed.
Implementation of the `sycl_kernel_launch()` function might require
additional information provided by the SYCL library. This is facilitated
by removing the previous prohibition against use of the
`sycl_kernel_entry_point` attribute with a non-static member function.
If the `sycl_kernel_entry_point` attributed function is a non-static
member function, then overload resolution for the `sycl_kernel_launch()`
function template may select a non-static member function in which case,
`this` will be implicitly passed as the implicit object argument.
If a `sycl_kernel_entry_point` attributed function is a non-static
member function, use of `this` in a potentially evaluated expression is
prohibited in the definition since `this` is not a kernel argument and
will not be available within the generated offload kernel entry point
function. The attribute cannot be applied to a function with an
explicit object parameter.

[ELF] Add target-specific relocation scanning for RISC-V (#181332)
Implement RISCV::scanSectionImpl, following the pattern established
for x86 (#178846) and AArch64 (#181099). This merges the getRelExpr
and TLS handling for SHF_ALLOC sections into the target-specific
scanner, enabling devirtualization and eliminating abstraction
overhead.
- Inline relocation classification into scanSectionImpl with a switch
on relocation type, replacing the generic rs.scan() path.
- Use processR_PC/processR_PLT_PC for common PC-relative and PLT
relocations.
- Handle TLS IE and GD directly (RISC-V does not optimize GD/LD/IE).
- Replace TLS-optimization-specific expressions for TLSDESC, following
the x86 pattern: R_RELAX_TLS_GD_TO_IE -> R_GOT_PC,
R_RELAX_TLS_GD_TO_LE -> R_TPREL. Update relocateAlloc and relax()
to dispatch on relocation type instead of RelExpr for TLSDESC.
- Simplify getRelExpr to only handle relocations needed by
relocateNonAlloc and preprocessRelocs.
- Remove RISC-V-specific checks from handleTlsRelocation (isRISCV
variable, TLSDESC label special cases).
- Move R_RISCV_VENDOR handling into the relocation type switch. An
undefined vendor symbol now gets the standard undefined symbol error
instead of a vendor-specific diagnostic.

[SandboxVec][DAG] Handle unscheduled successors when user is external (#183861)
Whenever an IR use-def edge gets updated, the DAG gets notified about
the change by having its `notifySetUse()` callback called. The
callback's job is to update the DAG node's `UnscheduledSuccs` counter
which is the number of successor nodes that are yet to be scheduled.
This update makes sense only if both ends of the use-def edge are in the
DAG. Up until now we would still update the counter even if the user was
outside the DAG. This patch fixes this, so from now on we skip updatinge
`UnscheduledSuccs` if the user is outside the DAG.

[libc++][string] Replace ASAN volatile wrapper with memory barrier (#184693)
The previous `_LIBCPP_ASAN_VOLATILE_WRAPPER` approach was used to
prevent
speculative loads of string data before the short/long state was
determined. This patch replaces that mechanism with a more explicit
`__annotate_memory_barrier()` using an empty volatile assembly block.
This PR is inspired by #183457 and by downstream false positive on
`__get_long_size`. It fails same way as `__get_long_pointer` before we
have
`_LIBCPP_ASAN_VOLATILE_WRAPPER`. Barrier approach avoids
expanding `_LIBCPP_ASAN_VOLATILE_WRAPPER` for size_t, and to
in general looks more readable.
I failed to create reasonable reproducer for test, I suspect it requires
precise set of compiler flags, and libc++ site_config which will be hard
to maintain in test.

[mlir] Improve dialect conversion failure diagnostics (#182729)
This PR improves MLIR dialect conversion failure diagnostics when
legalization fails.
Previously, the diagnostic mostly included the operation name (and in
partial conversion, whether it was explicitly marked illegal). This
change keeps that prefix and appends the printed failing operation. This
provides immediate operand/result/type context directly in the same
error line.
### Example
Before:
```
failed to legalize operation 'test.type_consumer' that was explicitly marked illegal
```
After:
```
failed to legalize operation 'test.type_consumer' that was explicitly marked illegal: "test.type_consumer"(%arg0) : (f32) -> ()
```
### Tests
- Updated `mlir/test/Transforms/test-legalizer.mlir` expectations for
the richer emitted diagnostic.

[MemProf] Enhance thin link optimization remarks (#184829)
Don't require -memprof-report-hinted-sizes for emitting opt remarks
during the thin link step. Invoke the handling also when opt remarks are
enabled for MemProf per OptimizationRemarkEmitter::allowExtraAnalysis.
Also, add a fallback message if we don't have the context size
information, adding tests for those new messages.
I also realized we don't currently emit these messages for MemProf with
regular LTO, and added a TODO.

[DA] Fix the Weak Zero SIV tests when the coeff may be zero (#183736)
In the Weak Zero SIV tests, given two subscripts `{c0,+,a}` and `c1`,
when `c0 == c1`, the tests conclude that a dependency exists from the
former subscript at the first iteration to the latter subscript at every
iteration. However, this conclusion is correct only when `a` is not
zero, which was not being checked.
This patch adds non-zero checks for `a` in the Weak Zero SIV tests.
Fix the test cases added in #183735 .

[WebAssembly] Do not form minnum/maxnum (#184796)
For wasm, forming minnum/maxnum style ISD nodes is non-profitable,
because (in cases where any float min/max support exists at all), it has
pmin/pmax instructions that correspond to the fcmp+select semantics, or
relaxed_fmin/relaxed_fmax (for the nnan+nsz case) with even loser
semantics.
As such, return false from isProfitableToCombineMinNumMaxNum(), and also
respect that hook in the SDAGBuilder.

[ORC] Make ElementSet, ContainerElementsMap inner classes. (#184955)
ElementSet and ContainerElementsMap were type aliases inside
WaitingOnGraph.
This commit replaces the aliases with classes deriving from DenseSet and
DenseMap, with convenience operations added for WaitingOnGraph (merge,
remove, remove_if, and visit). These convenience functions are used to
simplify the implementation of various parts of WaitingOnGraph.
Unit tests are added for the convenience operations to improve test
coverage.
In addition to improving readability of the main WaitingOnGraph
operations, this will make it easier to experiment with other underlying
representations for these types (e.g. sorted vectors).

they are unnecessary in the first place, it would be better to delete
them to mitigate maintenance burden.

[CodeGen] Use data layout aware constant folder in CGBuilder (#184819)
Use the DataLayout-aware TargetFolder instead of ConstantFolder in
Clang's CGBuilder. The primary impact of this change is that GEP
constant expressions are now emitted in canonical `getelementptr i8`
form. This is in preparation for the migration to ptradd, which requires
this form.
Part of the test updates were performed by Claude Code and reviewed by
me.

[mlir] [linalg] fix failure on specializing matmul with permuted loops (#184294)
This patch fixes generic specialization when the loop dimensions are
permuted in the generic w.r.t. to canonical iterator order of the named
ops by not forwarding the maps of the original generic and instead
recreating them ensuring they always follow the canonical order.
For example, the generic which is to be specialized to a matmul could
have `[parallel, reduction, parallel]` loops, specializing this as is
and just coping the indexing maps like we do now will lead to a
verification error since the dimension will not match the canonical form
the matmul named op expects
e.g. the maps could be:
```
(m, k, n) -> (m,k)
...
```
So we would have to recreate the maps to be:
```
(m,n,k) -> (m,k)
...
```

[lldb] Initial plugin and test for SymbolLocatorSymStore (#183302)
Minimal infrastructure for a the SymbolLocator plugin that fetches debug
info from Microsoft SymStore repositories. More features will follow.
SymbolVendorPECOFF was tailored towards DWARF debug info so far. This
patch adds code to load the PDB path from the executable and not bail
out if DWARF sections are missing, so that in the PDB case we still
call `AddSymbolFileRepresentation()` in the very end of
`CreateInstance()`.
The API test in this patch mocks the directory layout from SymStore, so
it doesn't depend on `SymStore.exe` from the Windows SDK. It runs on all
platforms that link debug info in a PDB file, which is still just
Windows, but it could be cross-platform in principle.

[AMDGPU] Make chain functions receive a stack pointer (#184616)
Currently, chain functions are free to set up a stack pointer if they
need one, and they assume they can start at scratch offset 0. This is
not correct if CWSR and dynamic VGPRs are both enabled, since in that
case we need to reserve an area at offset 0 for the trap handler, but
only when running on a compute queue (which we determine at runtime).
Rather than duplicate in every chain function the code sequence for
determining if/how much scratch space needs to be reserved, this patch
changes the ABI of chain functions so that they receive a stack pointer
from their caller.
Since chain functions can no longer use plain offsets to access their
own stack, we'll also need to allocate a frame pointer more often (and
sometimes also a base pointer). For simplicity, we use the same
registers that `amdgpu_gfx` functions do (s32, s33, s34). This may
change in the future. Chain functions never return to their caller and
thus don't need to preserve the frame or base pointer.
Another consequence is that now we might need to realign the stack in
some cases (since it no longer starts at the infinitely aligned 0).

[mlir][affine] Fix crash in super-vectorize when inner loop bounds depend on outer IV (#184770)
When affine-super-vectorize creates the vectorized version of an inner
loop whose bounds reference the outer loop's induction variable, it was
passing the original scalar bound operands directly to the new vector
AffineForOp. These operands reference block arguments of the scalar
outer loop, which are destroyed when the scalar loop nest is erased,
triggering a use_empty() assertion.
Fix this by replacing the bound operands with their scalar value
replacements (via getScalarValueReplacementsFor) before creating the new
vector loop, ensuring the vector inner loop uses the vector outer loop's
induction variable.

[mlir][bufferization] Fix crash in buffer-hoisting on unreachable blocks (#184094)
`BufferAllocationHoisting::hoist()` iterates over all allocations in a
function and tries to move them to their common dominator block. When an
allocation is in an unreachable basic block (a block that cannot be
reached from the function entry), the LLVM dominator tree has no node
for that block. Two subsequent calls would then crash:
1. `findCommonDominator` calls `findNearestCommonDominator` which calls
the LLVM DomTree equivalent and hits the assertion `NodeA && "A must be
in the tree"`.
2. `findPlacementBlock` calls `dominators.getNode(currentBlock)` on the
unreachable block, which returns null, causing a null dereference on
`->getIDom()`.
Fix by skipping allocations whose parent block is not reachable from the
entry block of the function. Such allocations are in dead code and there
is no need to hoist them.

[mlir][affine] Reject affine.for with step <= 0 in parser and verifier (#184158)
An affine.for loop with step 0 caused a crash in affine-loop-unroll due
to a division-by-zero assertion in getTripCountMapAndOperands:
llvm::divideCeilSigned(loopSpan, step) -- step == 0
The parser already rejected negative steps but allowed zero through.
Fix this by:
- Updating the parser to reject any step <= 0 (not only negative).
- Adding a verifier check in AffineForOp::verifyRegions() so that loops
constructed programmatically with an invalid step are caught before any
analysis pass runs.
- Adding a defensive early-return guard in getTripCountMapAndOperands
for step <= 0, consistent with getTrivialConstantTripCount which already
performs this guard.

[mlir][scf] Fix crash in loopUnrollJamByFactor for zero trip count loops (#184620)
When loopUnrollJamByFactor is called on a loop with a zero trip count
(e.g., lb == ub), the function correctly detects that the unroll factor
exceeds the trip count and adjusts it to match. However, capping the
factor at 0 leads to unsigned underflow when computing the SmallVector
size for `operandMaps(unrollJamFactor - 1)`, resulting in an attempt to
allocate ~2^64 elements and an immediate crash.
Add an early return when the trip count is zero, matching the pattern
already used by loopUnrollFull. A loop that executes zero times needs no
unrolling.

[mlir] Defer `LoopLikeOpInterface` type checks to `RegionBranchOpInterface` (#184116)
`LoopLikeOpInterface`'s verifier hardcodes type equality checks for
init/iter_arg/yield/result edges. This prevents downstream ops with
compatible-but-unequal types from using the pass verifier, since there
is no override mechanism.
`RegionBranchOpInterface` already verifies types along all control-flow
edges and provides an overridable `areTypesCompatible` hook. In
practice,
most loop ops implement both interfaces, making the
`LoopLikeOpInterface`
type checks redundant (the existing code even had a comment
acknowledging
this).
This PR removes the redundant type checks from `LoopLikeOpInterface`
when the op also implements `RegionBranchOpInterface`, letting that
interface handle type compatibility (including any custom
`areTypesCompatible` overrides). For ops that only implement
`LoopLikeOpInterface` (e.g. `affine.parallel`, `tosa.while_loop`), the
strict type equality checks are retained as a fallback. the verifier's
loop-result check to use structured bindings with `llvm::enumerate` and
remove dead variables.

[AArch64][Thumb2] Add missing select FMF in tests
These currently have the "fast" flag on the fcmp, but not the
select. The transform actually needs it (or more specifically the
nsz flag) to be on the select for correctness, but due to an
implementation bug it's currently accepted on the fcmp as well.
I don't believe the intent of any of these tests is to test
specifically the "fast fcmp with non-fast select" situation,
so add the missing flag to the select instructions.

[InstCombine] Canonicalize GEP source element types (#180745)
Canonicalize GEP source element types from `%T` to `[sizeof(%T) x i8]`.
This is intended to flush out any remaining places that rely on GEP
element types, as part of the `ptradd` migration. The impact of this
change is expected to be fairly minimal (we might enable a few more
hoist/sink style folds that depend on equal GEP types).

-march=hexagon uses the default target triple and changes the arch part

[CI][libsycl] Add libsycl precommit testing job (#184174)
We want to add some basic precommit CI for `libsycl`, similar to what we
have for `SPIR-V`.
Here it just builds `libsycl` and runs `check-sycl`, but only non-GPU
tests will be run because this job is run on GitHub-hosted runners which
don't have a GPU, so we will never run GPU tests in this CI job.
Postcommit already runs SYCL GPU tests.
We have runtime GPU detection as part of the `check-sycl` lit setup so
everything works fine.
Currently there is only one `check-sycl` test at all and it is a GPU
test, so `check-sycl` is basically a no op, so this is de-facto build
only.

[LV] Support interleaving with FindLast reductions (#184099)
This extends the existing support to work with arbitrary interleave
factors. The main change here is reworking the ExtractLastActive
VPInstruction to take a variable amount of arguments and handling it in
unrollRecipeByUF and VPInstruction::generate.
The select condition for all mask/data values in a find-last recurrence
is the true if the mask for any part is true. Because of this the masks
for inactive parts will be updated to all-false when the parts with
active lanes are updated. This ensures the mask/data for last active
element always corresponds to the greatest part with an active lane.
This means finding the last element in the middle block simply requires
chaining the `extract.last.active` to forward the result from the last
active part through any inactive parts ahead of it.

[ConstantFolding] Consider `tanh*` to always be a noop (#70794)
fixes https://github.com/rust-lang/rust/issues/108965
Most trigonometry functions are already considered, but tanh* was
missing. According to POSIX, these functions may fail on subnormals, so
we choose not to fail, allowing the calls to be eliminated.
https://pubs.opengroup.org/onlinepubs/9699919799/functions/tanh.html
The existing test llvm/test/Transforms/InstSimplify/ConstProp/calls.ll
already eliminated the call since it marked tanh as `nounwind`, which
causes it to be eliminated as well.
I am not sure whether I should add a new test without the `nounwind` or
whether it makes more sense to remove the `nounwind` from the existing
tests.

[mlir][test] Reject TestWithBoundsOp with mismatched attribute width in verifier (#184093)
Add a verifier to `TestWithBoundsOp` that rejects bounds attributes
whose
bit width does not match the result type's storage width (e.g., `10 :
i64`
for an `i8` result). This makes the mismatch invalid IR rather than
silently
accepting it, preventing downstream crashes in consumers such as
`TestReflectBoundsOp::inferResultRanges` that assert on matching widths.
`inferResultRanges` is reverted to its original one-liner; the new
`verify()` method enforces the invariant at IR construction time.
A dedicated test file (`infer-int-range-test-ops-invalid.mlir`) uses
`-verify-diagnostics` to check the emitted error message.

[CUDA/HIP] Do not ignore complete destructors in abstract classes (#184894)
Summary:
The complete destructor destroys virtual base subobjects even for
abstract classes, so target inference must consider vbases when
analyzing destructors.
This was motivated by behavior observed from a bug where a constexpr
function that calls a non-constexpr function. I believe this error is
secondary, but can be fixed by this observation. The issue was the
switch to C++20 allowing allocator destructors to be constexpr began
opting the function into `__host__ __device__` contexts. This function
then called a non-constexpr function through a type-trait interface
which lead to that only having `__host__` which is illegal.
The fix offered here is to check the bases of this function and
correctly derive that it is `__host__` and not `__host__ __device__` as
was previously inferred. This should only affect cases where the *only*
member is an inherited virtual destructor. Previously we found no bases
and thus made no judgement.

Summary:
This, as far as I am aware, has mostly been superceded by the runtimes
build that's built on top of libc. This build links 30% faster, supports
more functionality, and uses 95% less disk space, so it seems to be the
direction we want to go.
CUDA support remains, this is not needed urgently.

[mlir] Add option to cloning for different results (#184202)
With his permission while he is away, I am resurrecting @zero9178's very
first MLIR PR #65171 that adds an option to change result in the
operation cloning mechanism. This is very useful as cloning is currently
the only way to change the results of an operation.
> Since Operations cannot change the results after creation, a clone is
necessary to create new results. Doing such an operation generically has
not been possible so far. This PR therefore adds a new option to the
CloneOptions struct allowing adding changing the results of the created
operation.
>
> The caller is responsible to ensure that this is a valid operation and
setting the IRMapping accordingly afterwards if required.

[C++20][Modules] Do not apply `getAdjustedOffset` to file-internal byte offset. (#184956)
In https://reviews.llvm.org/D137214 and
https://reviews.llvm.org/D136624, offset adjustment logic was added to
account for the non-affecting module map files that are removed. While
the adjustment logic applies to global source location offsets, they do
not apply to file-internal offsets (relative within the file).
In `ASTWriter::WritePragmaDiagnosticMappings`, the adjustment is applied
to `StatePoint.Offset`s in `StateTransitions`. However, these offsets
are file-internal offsets, not global source location offsets. As such,
applying adjustment to these offsets result in incorrect diagnostic
behavior from the module.
Specifically, wrapping a piece of code in `pragma clang diagnostic
push/pop`, inside of a module is not applied correctly. A new test case
`diag-pragma-nonaffecting.cpp` was added to verify the broken behavior
as well as the corrected behavior with this commit.

[MLIR] Fix crash in inliner when return arity mismatches call results (#185037)
The `handleTerminator` implementation in the test dialect's inliner
interface was asserting that the number of `test.return` operands equals
the number of values to replace. This assertion fires when inlining a
callee whose body uses `test.return` with values into a call site that
expects zero results (e.g., a void `llvm.func` calling a function whose
implementation uses `test.return` with operands).
Replace the assertion with a conditional early return so the inliner
gracefully skips replacement instead of crashing.

[lldb][windows] fix VT sequences overriding (lldb) prompt (#183366)
This patch fixes the `(lldb)` prompt being overwriten by the cursor
position movements the ConPTY emits.
To be a complete solution we should also add a resize hook for the
console's window.
I also think that we should look into injecting conpty VT sequences
before printing the `(lldb)` prompt.
For instance, if we break on a breakpoint and the pty added a "hide
cursor" VT sequence, we should emit a `show cursor` sequence before
printing `(lldb)`. This should be done outside of this PR however.
