with.
This clarifies the sentence about assumptions when there is no attribute

[Clang] support C23 constexpr struct member access in constant expressions (#182770)
Fixes #178349
---
This patch resolves an issue where accessing C23 `constexpr` struct
members using the dot operator was not recognized as a constant
expression.
According to C23 spec:
> 6.6p7:
>
> An identifier that is:
> — an enumeration constant,
> — a predefined constant, or
> — declared with storage-class specifier constexpr and has an object
type,
> is a named constant, as is a postfix expression that applies the .
member access operator to a named
> constant of structure or union type, even recursively. For enumeration
and predefined constants,
> their value and type are defined in the respective clauses; for
constexpr objects, such a named
> constant is a constant expression with the type and value of the
declared object.
>
> § 6.6p13:
>
> A structure or union constant is a named constant or compound literal
constant with structure or
> union type, respectively
>
> § 6.6p15:
>
> Starting from a structure or union constant, the member-access .
operator may be used to form a
> named constant or compound literal constant as described previously in
this subclause

[VPlan] Add nuw to unrolled canonical IVs (#183716)
After #183080, the canonical IV (not the increment!) can't overflow. So
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.

Implement `ProcessFreeBSDKernelCore::DoWriteMemory()` to write data on

wrong value on `/dev/mem` can trigger kernel panic), this feature is
only enabled when `plugin.process.freebsd-kernel-core.read-only` is set
to false (true by default).
Since 85a1fe6 (#183237) was reverted as it was prematurely merged, I'm

[SPIRV][NFCI] Use unordered data structures for SPIR-V extensions (#183567)
Review follow-up from https://github.com/llvm/llvm-project/pull/183325
No reason for these data structures to be ordered.
Minor annoyance when trying to use `DenseMap` because of the C++ code
for enums generated by TableGen, but not too bad.

[clang][DebugInfo] Rename _vtable$ to __clang_vtable (#183617)
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.

represent indirect references, handles indirect symbols within
`setSymbolAttribute()` by setting the indirect reference bit, and also
updates the HLASM streamer to emit `XATTR REFERENCE(INDIRECT)` and
various other combinations.

Builds using libc++ hardening was hitting asserts like

!__comp(*(__first + __a), *(__first + __b)) failed:
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.

[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.

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.

[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)

Supersedes #179722
Fixes #47793
Fixes #165041 (probably)
Thanks to @jkbz64 for the initial investigations (w/ AI; see #179722)
into why this pass was slow and memory consuming and showing that SCCs
were the key.
Also thanks to the Cheerp compiler project for bringing `SCCIterator` to
light in this context ([blog
post](https://cheerp.io/blog/control-flow#fix-the-irreducible-control-flow),

[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.

This PR adds `JSONFormat` support for reading and writing

structures of `TUSummary` and `TUSummaryEncoding` by reusing existing
`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

[SystemZ] Emit external aliases for indirect function descriptors in the ADA section (#183443)
This is the last of the three patches aimed to support indirect symbol
handling for the SystemZ backend.
An external alias is emitted for indirect function descriptors within
the ADA section, rather than a temporary alias, while also setting all
of the appropriate symbol attributes that are needed for the HLASM
streamer to emit the correct XATTR and ALIAS instructions for the
indirect symbols.
Moreover, this patch updates the
`CodeGen/SystemZ/zos-ada-relocations.ll` test as the ADA section is
currently the only user of indirect symbols on z/OS.
Depends on https://github.com/llvm/llvm-project/pull/183442.

[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
* Fixes https://github.com/llvm/llvm-project/issues/63271
* Fixes https://github.com/llvm/llvm-project/issues/86240

[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

[mlir][arith] Add `exact` to `index_cast{,ui}` (#183395)
The `exact` flag with the following semantics
> If the `exact` attribute is present, it is assumed that the index type
width
> is such that the conversion does not lose information. When this
assumption
> is violated, the result is poison.
can be added to index_cast and index_castui operations. This unlocks
the following lowerings:
* index_cast (signed) exact -> trunc nsw
* index_castui (unsigned) exact -> trunc nuw
* index_castui nneg exact -> trunc nuw nsw
Changes:
* Adds ArithExactFlagInterface.
* Updates Arith_IntBinaryOpWithExactFlag to use ArithExactFlagInterface
* Update IndexCastOp and IndexCastUIOp to declare
`ArithExactFlagInterface`
* Update canonicalization patterns
* Update roundtrip, lowering, and canonicalization tests.

[lldb] Add synthetic support to formatter_bytecode.py (#183804)
Updates formatter_bytecode.py to support compilation and disassembly for
synthetic formatters, in other words support for multiple functions
(signatures).
This includes a number of other changes:
* 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.

[CIR] Fix dominance problems with values defined in cleanup scopes (#183810)
We currently encounter dominance verification errors when a value is
defined inside a cleanup scope but used outside the scope. This occurs
when forceCleanup() is used to exit a cleanup scope while a variable is
holding a value that was created in the scope body. Classic codegen
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.

- Introducing the LangAddressSpace enum with offload address space kinds
(offload_private, offload_local, offload_global, offload_constant,
offload_generic) and the LangAddressSpaceAttr attribute.
- Generalizes CIR AS attributes as MemorySpaceAttrInterface and Attaches
it to `PointerType`. Includes test coverage for valid IR roundtrips and
invalid address space parsing.
This starts a series of patches with the purpose of bringing complete
address spaces support features for CIR. Most of the test coverage is
provided in subsequent patches further down the stack. note that most of
these patches are based on: https://github.com/llvm/clangir/pull/1986

[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.

[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
between versions AFAIK, so re-used the DWARF5 `FileCheck` in the test.
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.

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.

[mlir] Fix crash in testNoSkipErasureCallbacks on empty blocks (#183757)
The `noSkipBlockErasure` callback in `testNoSkipErasureCallbacks` called
`block->front().getParentRegion()` to get the parent region of a block.
This dereferences the ilist sentinel node when the block has no
operations, triggering an assertion failure.
Use `block->getParent()` instead, which directly returns the region
containing the block without requiring any operations to be present.

[mlir][affine] Fix crash in linearize_index fold when multi-index is ub.poison (#183816)
`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.

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.

[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.

This enables selecting riscv64 and reading registers from PCB structure
on core dump and live kenrel debugging while trapframe unwinding support
will be implemented in future. Test files using core dump from riscv64
will be implemented once other kernel debugging improvements are done.

[mlir][spirv] Fix crash when spirv.struct member type is not a SPIR-V type (#183942)
When parsing a spirv.struct type, any MLIR type was accepted as a member
type without validation. This caused a crash in TypeExtensionVisitor and
TypeCapabilityVisitor which unconditionally used cast<SPIRVType> on
struct element types, asserting when a non-SPIR-V type (e.g.,
vector<2x2xi1>) was encountered.
Fix the parser to reject non-SPIR-V member types with a proper error
message.
Fixes #179675

[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.

You can pass the stdlib argument either as -stdlib and --stdlib - the

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:

[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.

[clang][NFC][diagnostics] Remove several uses of `getCustomDiagID()` (#172532)
This change converts all existing uses of `getCustomDiagID()` within the
`clang/AST` library into regular diagnostics defined in
`DiagnosticASTKinds.td`.
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.

[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

This helps canonicalize some address calculation. This would further

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.

valid but obviously not profitable (e.g. for trivially movable types)

This PR fixes the bug that TrivialFunctionAnalysis can ignore nodelete

not check the annotation on prior declarations unlike
alpha.webkit.NoDeleteChecker which checks it on any declaration by
replacing isNoDeleteFunction with NoDeleteChecker's
hasNoDeleteAnnotation.

Use `GlobalWriteProfileMutex` to synchronize between data reset and

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).

`IOAddressMap` won't be set up, we should check if the map actually

[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.

[flang][OpenMP] Implicitly capture variables in enclosing task for nested firstprivate (#183770)
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:
https://discourse.llvm.org/t/rfc-clarify-the-behavior-of-fp-operations-on-bit-strings-with-nsz-flag/85981

[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
cost model that the vector intrinsic form of llvm.pow is cheap in the
presence of the library.

[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.

[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`.

[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.

[CVP] Stop CVP constant propagation from destroying `llvm.assume` (#183688)
For following code sequence:
```
%cmp = icmp ugt i64 %idx, 1
tail call void @llvm.assume(i1 %cmp)
```
CVP may replace all use of `%cmp` with `true`, and the information about
`%idx` is lost. This commit stop CVP from doing that, so that later pass
can exploit the `llvm.assume`.

[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
```

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.

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}`.

Implement support for the OpenMP `mapper` modifier on `target update` `to` and

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.

[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

in `InitListChecker::CheckMatrixType` in `clang/lib/Sema/SemaInit.cpp`.
This PR also makes the codegen respect /Zpr and /Zpc during codegen for

[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.

[APINotes][NFC] Fix typos and header comment errors (#183811)
## 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.

[clang][deps] Remove the `finalize()` API for by-module-name scans (#184232)
The `DiagnosticConsumer::finish()` API was removed in #183831. Since
that was the only thing the by-module-name `finalize()` API called, we
can safely remove that and simplify the scanner.

[clang][clang-scan-deps] Add LangOptions::AllowLiteralDigitSeparator to fix #88896 (#184235)
Fixes #88896 by following the approach described in
https://github.com/llvm/llvm-project/pull/95798#discussion_r1649496882.
This adds `LangOptions::AllowLiteralDigitSeparator`, following the
pattern used for `RawStringLiterals` in #88265.
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.

we just implement it directly in codegen.

[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.

[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.

https://github.com/llvm/llvm-project/pull/178358 as well.

[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.

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.*

[mlir][acc] Add ACCRecipeMaterialization pass and reduction ops (#184252)
Pass
----
Add the `acc-recipe-materialization` pass, which materializes OpenACC
privatization, firstprivate and reduction recipes by inlining their
init, copy, combiner, and destroy regions into the operation for the
construct. The pass runs on acc.parallel, acc.serial, acc.kernels, and
acc.loop.
- Firstprivate: Inserts acc.firstprivate_map so the initial value is
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.

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.

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.

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.

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.

[mlir][sparse] Fix crash in ForeachRewriter for rank-0 dense tensors (#183903)
sparse_tensor.foreach over a rank-0 (scalar) dense tensor crashed
because ForeachRewriter delegated entirely to LoopEmitter, which builds
one loop level per tensor dimension. For rank-0 tensors no loops are
created, so getValPosits() called std::vector::back() on an empty
container.
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.
Fixes #130021

[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
...
%expand = vector.shape_cast <...> : vector<1xindex> to vector<1x1xindex>
%gather = vector.gather %weight[%c0] [%expand], <...>, <...> : memref<256xi8>, vector<1x1xindex>, vector<1x1xi1>, vector<1x1xi8> into vector<1x1xi8>
%collapse_back = vector.shape_cast %gather : vector<1x1xi8> to vector<1xi8>
// Example 2: multi-reduction
%expand = vector.shape_cast <...>: vector<1x96xi32> to vector<1x2x48xi32>
%reduce = vector.multi_reduction <add>, %expand, <...> [1, 2]: vector<1x2x48xi32> to vector<1x1xi32>
%collapse = vector.shape_cast %reduce : vector<1x1xi32> to vector<1xi32>
```
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.

[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

Reapply https://github.com/llvm/llvm-project/pull/183567 with minor
changes.
Problem causing the revert was we couldn't use the enum in `DenseMap`
directly because of some `TableGen` limitations so I casted made the map
use the underlying type, but that caused some UB, so I
[fixed](https://github.com/llvm/llvm-project/pull/183769) the `TableGen`
limitation so now it just works.

[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.

[HIP] Fix -save-temps with the new offload driver (#184385)
Summary:
The new offloading driver passes LLVM-IR to the linker phase. This
caused a problem with `-save-temps` passing unoptimized bitcode. We were
supposed to have dedicated handling for this, but it was not firing in
the HIP case like it is supposed to. OpenMP already supports this so
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

[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.

implementation that doesn't do awfully much.
This patch implements both, plus the name through the itanium ABI.

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.

[CIR] Implement EH lowering to Itanium form and LLVM IR (#184386)
This introduces a new pass to lower from a flattened, target-independent
form of CIR to a form that uses Itanium-specific representation for
exception handling. It also includes a small amount of code needed to
lower the Itanium form to LLVM IR.
Substantial amounts of this PR were created using agentic AI tools, but
I have carefully reviewed the code, comments, and tests and made changes
as needed.

[lldb] Fix 10 year old leak of `g_debugger_list_ptr` (#184259)
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:

[lldb] AArch64 register 33 is not cpsr (#183860)
I have an unwind failure where the eh_frame for a
trap handler states that the caller's return address is in eh_frame
register 33, which lldb treats as cpsr.
https://github.com/ARM-software/abi-aa/blob/main/aadwarf64/aadwarf64.rst#dwarf-register-names
Register 33 is ELR_mode, which isn't defined as a register in any of the
AArch64 register definition files in lldb today, so I'm not adding it to
the header files.

[lldb] Remove Debugger::{FindTargetWithProcessID, FindTargetWithProcess} (#184446)
In #184259, Jim noticed that Debugger::FindTargetWithProcess and
Debugger::FindTargetWithProcessID are rather poorly designed APIs as
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.

[Clang] Permit floating point and pointer values in most atomic ops (#183843)
Summary:
We already support floating point arguments for the standard atomic
functions. LLVM supports these in most cases as well. This PR unifies
the handling and allows this in the cases that the LLVM IR supports.

[X86] support reserve r8~r15 on X86_64 (#180242)
Which is under discussion in
https://github.com/llvm/llvm-project/issues/179036
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
results.
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.

See the comments in ASTDeclReader::attachPreviousDeclImpl .

[Hexagon] Ignore formatting of generated proto files (#184427)
hexagon_protos.h, hexagon_circ_brev_intrinsics.h, and
hvx_hexagon_protos.h are generated C header files that consist of
macro definitions and help fields in comments. These files are large.
Automatic formatting of these files breaks their regular structure
and increases maintenance effort.

[RISCV][GISel] Replace buildInstr with BuildMI (#183714)
As @arsenm mentioned in some of my PRs, such as:
https://github.com/llvm/llvm-project/pull/171092, we should use
`BuildMI` instead of `MachineInstrBuilder::buildInstr` in Selector.
This PR is tring to replace all `MachineInstrBuilder::buildInstr` with
`BuildMI`.

[clang][CIR] Pass VFS to command-line parsing (#184226)
This explicitly passes Clang's VFS to MLIR command-line parsing that
runs when ClangIR is enabled. This matches the rest of Clang and fixes a
sandbox violation.

[clang-tidy] Fix false positive in readability-redundant-preprocessor for builtin checks (#181734)
Different `__has_builtin()` checks were incorrectly flagged as redundant
because ConditionRange collapsed after macro expansion. It now reads
condition text directly from source to fix this.
