[ELF] --why-live: Skip symbol at index 0 and section symbols, handle .eh_frame symbols (#177099)
Symbols of empty names can be matched by `--why-live='*'`, which are
generally not useful.
* The first entry in a symbol table (STB_LOCAL and undefined)
* `STT_SECTION` symbols (emitted by LLVM integrated assembler when
needed by relocations). These input section symbols will be demoted by
`demoteAndCopyLocalSymbols`, so technically not really live.
In addition, such symbols of non-allocable sections currently lead to
crashes: `whyLive` does not record the section, causing the second
iteration of the `while (true)` loop in printWhyLive to call
`std::get<Symbol *>(cur)` when `cur` is an `InputSectionBase *`.
In addition, handle GCC crtendS.o `__FRAME_END__`, which is defined
relative to a `.eh_frame` section created with
`__attribute__((used, section(".eh_frame")))`.

[orc-rt] Actually test orc-rt/bit.h functions. (#177300)
The unit test was copied from a similar test in llvm, and was still
qualifying calls with 'llvm::'. This was unintended, but happened to
work because LLVM's bit.h is transitively included through LLVM's gtest
headers. Qualifying with 'orc_rt::' tests the intended functions.

[IR] Update IRBuilder::createVectorSplice to allow variable offsets (#177178)
Following on from #174693, this updates IRBuilder to allow variable
offsets, and splits the createVectorSplice function into two functions
for left and right splices.
We could preserve the existing createVectorSplice API but given there's
only one LLVM-internal user of it in the loop vectorizer, and the notion
of a negative offset doesn't exist in the intrinsics anymore, I've
removed it. Happy to add it back if reviewers prefer though.
I've also added unit tests since createVectorSpliceLeft has no coverage
otherwise.

[orc-rt] Implement rotl / rotr, fix missing include in unit test. (#177305)
In e838f27e0f3 the EndianTest.cpp unittest was updated to avoid using
`llvm::rotl` function, but the corresponding `orc_rt::rotl` function had
not been implemented yet.
This commit implements orc_rt::rotl, orc_rt::rotr, and
orc_rt::has_single_bit by copying their definitions from the
corresponding LLVM header (llvm-project/llvm/include/llvm/ADT/bit.h).
Unit tests for these functions are also copied from their LLVM
counterparts.

Fixes a crash reported post-commit in #171231. getCommonSubClass
returned one of these classes, but it doesn't have the same VTs as

The subregister-undef-early-clobber.mir still ends up finding these

[Modules] Fix spurious errors about module input file changing after .pcm file was built. (#176537)
For incremental multi-process/multi-thread compilation utilizing a build
session fix errors like
> fatal error: file '/path/to/Frmwrk.framework/Headers/Header.h' has been modified since the module file '/path/to/ModuleCache.noindex/XXX/Frmwrk-YYY.pcm' was built: mtime changed (was aaa, now bbb)
Another symptom of the bug is when you check Frmwrk.pcm the header's
mtime is correct, so it is confusing where "was aaa" is even coming from.
The main problem is that in case of a signature mismatch
`ModuleManager::addModule` returns `OutOfDate` but keeps .pcm buffer in
`InMemoryModuleCache`. So if later on it tries to use such a module, it
would have an outdated buffer in `InMemoryModuleCache`. If another
process/thread happens to rebuild such module and write a new validation
timestamp, the original process would skip the input file validation and
would keep using the outdated .pcm buffer hitting errors about
unexpected input modifications.
I want to note that in the current implementation the validation
timestamp can be still incorrect. When we are writing AST we don't
account for the case when an input file is modified after its mtime and
size are captured. We are relying on the input files not being modified
while building a module using these files.

vector.transpose -> vector.shape_cast.
This PR canonicalizes
%0 = vector.broadcast %arg0 : vector<4xi8> to vector<1x1x4xi8>
%2 = vector.extract %arg2[0] : vector<4xi8> from vector<1x4xi8>
to shape_cast. It was decided (see
https://github.com/llvm/llvm-project/pull/140583) that the
vector.transpose -> vector.shape_cast needs further consideration before
being added.

[MC] Explicitly use memcpy in emitBytes() (NFC) (#177187)
We've observed a compile-time regression in LLVM 22 when including large
blobs. The root cause was that emitBytes() was copying bytes one-by-one,
which is much slower than using memcpy for large objects.
Optimization of std::copy to memmove is apparently much less reliable
than one might think. In particular, when using a non-bleeding-edge
libstdc++ (anything older than version 15), this does not happen if the
types of the input and output iterators do not match (like here, where
there is a signed/unsigned mismatch).
As this code is performance sensitive, I think it makes sense to
directly use memcpy.
Previously this code used SmallVector::append, which explicitly uses
memcpy.

an infinite loop.
Fix by adding a check (PhiTy == ConvertTy) in optimizePhiType to skip
the conversion when types are already identical.

Fix EXTEND_VECTOR_INREG widening when input > result size (#177095)
This patch fixes an LLVM crash on AMDGPU that occurred when compiling
valid code involving non-power-of-two vector sizes. During type
legalization, LLVM widened an EXTEND_VECTOR_INREG operation by first
widening the input vector, which could make the input larger than the
result and trigger an assertion failure.
The fix changes the logic to widen the result first and then extract the
needed portion so there's no invalid size mismatch. I've added a test
that previously crashed but now doesn't.
fixes #176966.

[LLVM] Update the default value for MaxLargeFPConvertBitWidthSupported to 128 (#176851)
Previously, we can't compile the program which convert 256 bits to
floating points and vice versa(we'll crash). After this, we're able to
compile them.

[AArch64] Fix partial_reduce v16i8 -> v2i32 (#177119)
The lowering doesn't need to check for `ConvertToScalable`, because it
lowers to another `PARTIAL_REDUCE_*MLA` node, which is subsequently
lowered using either fixed-length or scalable types.

UBSAN stopped reporting the misaligned load since https://github.com/llvm/llvm-project/commit/5569bf26f0097c2d8b088f0a7cf46451da752dea so this test started failing. We skipped it to unblock CI.
There's been discussion on making UBSAN stricter and still trigger on
the one-line version of this. But for now, to get the test running
again, change it to a form which *does* trigger UBSAN.

[LoopInterchange] Support the inner-loop reduction via Reduction2Mem (#172970)
Following our
[discussion](https://discourse.llvm.org/t/rfc-plan-to-improve-loopinterchange-by-undoing-simple-reductions/89071),
I ported GCC’s undo_simple_reduction into LLVM.
**Key changes**
- Implement an Reduction2Memory step in LoopInterchange to support the
reduction in the inner loop.
- The feature is behind an option `-loop-interchange-reduction-to-mem`
and is OFF by default. With the feature off, the pass behaves as before
(minimal impact).
- Add a regression test.
**Validation & performance**
- No compile or semantic errors observed on SPEC2006 and SPEC2017 with
the new feature enabled for validation.
- With options: `-da-disable-delinearization-checks` and
`-loop-interchange-reduction-to-mem`
- SPEC2006 410.bwaves on x86 (Intel i9-11900K, Rocket Lake): **+6%**
- SPEC2017 603.bwaves_s on x86 (Intel i9-11900K, Rocket Lake): **+6%**
- SPEC2006 410.bwaves on SpacemiT Key Stone K1: **+29%**
- SPEC2006 410.bwaves on KMH RTL: **+56%**
- SPEC2017 603.bwaves_s on KMH RTL: **+24%**
**Note**
- Reduction2Memory only runs when legality and profitability checks
indicate the interchange will actually be performed. If interchange is
illegal or not profitable, no reduction2mem is applied.

ABI lowering code away from LoweringPrepare, thus the patch also removes
the LoweringPrepareCXXABI classes and files.

[SPIRV] Unify unsized array handling for AMGCN flavoured SPIR-V (#175848)
Currently we handle 0-sized arrays in multiple places, non-uniformly,
either via `SPIRVLegalizeZeroSizeArrays` or via `SPIRVPrepareGlobals`.
For AMDGCN flavoured SPIR-V we have a singular, simpler solution: set
all 0-sized arrays to be `UINT64_MAX` sized. This is an unambiguous
token that we can use during reverse translation to restore the intended
0 size.

AMDGPU: Select VGPR MFMAs by default (#159493)
AGPRs are undesirable since they are only usable by a
handful instructions like loads, stores and mfmas and everything
else requires copies to/from VGPRs. Using the AGPR form should be
a measure of last resort if we must use more than 256 VGPRs.

[Clang] Rename `uinc_wrap` and add normal atomic builtin (#177253)
Summary:
The `__scoped_atomic` builtins are supposed to match the standard
GNU-flavored `__atomic` builtins. We added a scoped builtin without a
corresponding standard one before the fork so this should be added in
the release candidate. These were originally added in
https://github.com/llvm/llvm-project/pull/168666
Also, the name `uinc_wrap` does not follow the naming convention. The
GNU atomics use `fetch_xyz` to indicate that the builtin returns the
previous location's value as part of the RMW operation, which these do.
This PR renames it and its uses.

All the BMI node combines seem to just call SimplifyDemandedBits - so
I've merged them into a single combineBMI.

the first register in the class, and whether or not the register class
is shrunk by RVE.
I've added a template function that takes this information and used the
DecoderMethod in tablegen to provide the values for the the template
parameters.
I kept an alias for DecodeGPRRegisterClass because it has multiple
callers.

[clang][modules] Read PCM validation timestamp earlier (#177062)
When building a module, the PCM file is always written first and then
the validation timestamp gets created. Clang needs to first read the
validation timestamp and only then read the PCM file. Otherwise, it
could read an out-of-date PCM file and then read the validation
timestamp for its new up-to-date version. This would erroneously skip
validation with `-fmodules-validate-once-per-build-session`. I'm not
concerned about multiple Clang instances seeing different filesystem
contents from each other within a single build session, since that would
break the assumption `-fmodules-validate-once-per-build-session` relies
on.

This patch adds a missing guard to the AArch64 ConditionOptimizer pass
Previously, the cross-block optimization would not check for register
equivalence before modifying the two comparison instructions.
This means that two cmp instructions with suitable cond codes and
immediates would be modified, even if their registers were different,
which would not trigger CSE afterwards. This doesn't affect correctness
but is unhelpful.
A negative ll test and mir tests has also been added to confirm this
fix.

[flang] Allow multiple identical DATA initializations (#177063)
ISO Fortran disallows DATA statements from affecting the same bit of
memory more than once; however, all (but one) other compilers allow this
usage. They differ, however, in the case of multiple distinct
initializations -- some compilers take the "last" value in source order,
some don't.
This patch accepts multiple identical DATA initializations, which is
portable usage that appears in code, and emits an optional warning. It
continues to detect and report multiple distinct DATA initializations,
since they are not portable.

[AArch64] Optimize memcpy for non-power of two sizes (#168890)
The previous getMemcpyLoadsAndStores implementation would chain
load/store instructions from "NumLdStInMemcpy - GlueIter -
GluedLdStLimit" to "NumLdStInMemcpy - GlueIter". This approach caused
issues when copying non-power-of-two sizes, as it would chain leading
load/stores with subsequent instructions at non-power-of-two aligned
offsets.
This chaining pattern prevented optimal optimizations in
aarch64-ldst-opt pass for these load/store instructions.
This commit modifies the chaining range to be from GlueIter to GlueIter
+ GluedLdStLimit, enabling proper optimization of load/store
instructions in aarch64-ldst-opt.

[SPIRV] Process indirect function calls immediately (#177222)
The SPIR-V backend processes indirect function calls in
`SPIRVCallLowering`, which is a subclass of the generic `CallLowering`.
It intends to process them function by function, by first collecting all
indirect calls in a function, and then processing all of a function's
indirect calls at once when the call lowering for the function is about
to end.
Today, it relies on the `lowerReturn` virtual function to be called by
the generic call lowering infra to know the function processing is about
to end, and at that time it processes all of the collected indirect
calls and clears the vector of indirect calls.
The problem is that not all functions have return instructions. Every
basic block must have a terminator instruction, but it does
[not](https://llvm.org/docs/LangRef.html#terminator-instructions) have
to be a return.
In the failing case here, function `a` has an infinite loop, with every
iteration having an indirect call and a check to see if it should break
out of the infinite loop. There is a return instruction initially, but
it is optimized out in the middle end. There is also an unrelated
function `b` with no indirect calls.
During call lowering, information about the indirect call in `a` is
captured in the vector in SPIRVCallLowering, but since there is no
return instruction, it is never processed.
Then, function `b` is processed. `b` happens to have a return
instruction, so the indirect call from `a` is processed, but the
processing assumes that the indirect call is inside the function being
processed, and it writes to a `{function, register}->SPIRVType` map, but
the function is `b` not `a`.
This ends up causing the map to have an invalid SPIRVType for the
register in function `b`, and `b` happens to have a register of the same
type, causing an invalid result from the map lookup and thus invalid IR
(`G_ADDRSPACE_CAST` from `ptr addrspace(4)` to `i32`).
We can't move the indirect call processing into a seperate pass because
we lose required information after call lowering ends.
Here, we change the indirect call processing to be done immediately when
it is seen.
Comments say the reason the collect all then process style was done was
to get better type information for the caller of the indirect function
if an opaque pointer is an arg to the caller and the indirect function,
but [an existing test
case](https://github.com/llvm/llvm-project/blob/main/llvm/test/CodeGen/SPIRV/extensions/SPV_INTEL_function_pointers/fp-simple-hierarchy.ll)
seems to exercise this, and the test still passes after this change and
actually has the exact same assembly.
The test case added is a minimal example from `llvm-reduce`, so it's
just an infinite loop with no exit condition.

GlobalISel: Fix mishandling vector-as-scalar in return values (#175780)
This fixes 2 cases when the AMDGPU ABI is fixed to pass <2 x i16>
values as packed on gfx6/gfx7. The ABI does not pack values
currently; this is a pre-fix for that change.
Insert a bitcast if there is a single part with a different size.
Previously this would miscompile by going through the scalarization
and extend path, dropping the high element.
Also fix assertions in odd cases, like <3 x i16> -> i32. This needs
to unmerge with excess elements from the widened source vector.
All of this code is in need of a cleanup; this should look more
like the DAG version using getVectorTypeBreakdown.

AMDGPU: Change ABI of 16-bit element vectors on gfx6/7 (#175781)
Fix ABI on old subtargets so match new subtargets, packing
16-bit element subvectors into 32-bit registers. Previously
this would be scalarized and promoted to i32/float.
Note this only changes the vector cases. Scalar i16/half are
still promoted to i32/float for now. I've unsuccessfully tried
to make that switch in the past, so leave that for later.
This will help with removal of softPromoteHalfType.

[LLVM] Disable clang-format for TableGen files (#177002)
Clang-format is not very maintained for TableGen, and seems to make odd
choices that differ significantly from how humans write and read the
backend's tablegen.
For the moment, disable clang-format for TableGen files. This should
also apply when using `git clang-format`, which should help with newer
contributors who sometimes end up formatting td files by accident.

[RISCV] Replace RISCVISD::CLMUL* with ISD::CLMUL*. (#177386)
This patch does the minimum to remove RISCVISD::CLMUL*. It does not
remove existing intrinsics.
There's some missed optimizations for i32 CLMULH/CLMULR on RV64, but
those may be generic issues.
I've put the test cases in the existing files so it's more obvious what
the missed optimizations are by comparing within the file.

[bazel] Improve building on/for Windows (#171761)
Few things going on here:
- I think we should be able to use the blake3 x86-64 asm on windows with
some slight adjustments (sorry it's still named *_unix.S, renaming
seemed like a bit bigger project)
- `genrule` is really evil because it bakes the path to the host bash
into the command, which fails spectacularly when running on a
non-windows remote executor. Swap to `write_file`/`run_binary` rules to
mitigate it
- The existing windows linkopts do not work correctly for clang in mingw
mode
With this set of changes (as well as another one that rewrites
`bundle_resources.py` into C) I am able to hermetically cross-build
clang/lld/etc from a windows host to a (mingw) windows target on a linux
executor, and use the resulting compilers to compile C binaries/tests

[libc] Fix character converter in C++20 (#177421)
Internally character converter uses char8_t to represent a character.
Before C++20 we provide a typedef for it, but since C++20 it's a
keyword. The keyword version isn't listed in our is_integral, causing
countl to reject it as an invalid type. This patch just casts from
char8_t to int8_t to sidestep the issue, but in future we may want to
add char8_t, char16_t, and char32_t to our is_integral.

AMDGPU: Change ABI of 16-bit scalar values for gfx6/gfx7 (#175795)
Keep bf16/f16 values encoded as the low half of a 32-bit register,
instead of promoting to float. This avoids unwanted FP effects
from the fpext/fptrunc which should not be implied by just
passing an argument. This also fixes ABI divergence between
SelectionDAG and GlobalISel.
I've wanted to make this change for ages, and failed the last
few times. The main complication was the hack to return
shader integer types in SGPRs, which now needs to inspect
the underlying IR type.

[NFCI] replace getValueType with new getGlobalSize query (#177186)
Returns uint64_t to simplify callers. The goal is eventually replace
getValueType with this query, which should return the known minimum
reference-able size, as provided (instead of a Type) during create.
Additionally the common isSized query would be replaced with an
isExactKnownSize query to test if that size is an exact definition.

IR: Add !nofpclass metadata (#177140)
This adds the analogous metadata to the nofpclass attribute
to assert values are not a certain set of floating-point classes.
This allows the same information to be expressed if a function
argument is passed indirectly. This matches the bitmask encoding
of nofpclass.
I also think this should be allowed for stores to symmetrically handle
sret, but leave that for later.
Alternatively we could add a more expressive !fprange metadata,
but that would be much more complex. It's useful to match the attribute,
and more annotations can always be added.
Fixes #133560

[AMDGPU] Allow amdgpu-waves-per-eu to lower target occupancy range (#168358)
`amdgpu-waves-per-eu` currently does not allow users to lower the target
occupancy range that the backend will try to achieve. For example, for a
kernel targeting gfx942 with default flat workgroup sizes and no LDS
usage, `AMDGPUSubtarget::getWavesPerEU` will by default produce the
range [4,10]. Setting `"amdgpu-waves-per-eu=M,N"` (N being optional)
will only have an effect if 4 <= M <= N <= 10, in which case the [M,N]
range will be produced instead. Advanced developers may in some cases
know that a specifc kernel would not benefit from higher occupancies and
wish to communicate that to the backend. It in turns could make better
codegen decisions if it knows that increasing occupancy is not a
priority.
This modifies the computation of the waves/EU range to enable this
behavior. User-provided minimum/maximum number of waves/EU are now able
to change the default waves/EU range almost arbitrarily, with only
subtarget's specifications and the maximum occupancy induced by
workgroup size and LDS usage limiting the target occupancy range. In the
previous example, the target range will be [M,N] as long as 1 <= M <= N
<= 10.
To allow users to specify only a maximum desired number of waves per EU,
the attribute now accepts a minimum value of 0 and understands it as a
wish to not restrict the minimum number of waves per EU (a minimum value
of 1 indicates instead that the user is ok with an occupancy of 1, so it
cannot be used as the default).

[NVPTX] fix illegal name for .extern .shared global variables (#173018)
In ptx we can create a GV in AS(3) that will be compiled to a `.extern
.shared` in ptx. Since the `.extern .shared` is not an "extern" in the
traditional sense of the word it will not be linked based on name but
rather refer to the shared memory allocated at kernel launch.
Since we don't care about the name it's tempting to make the GV unnamed.
Then the problem that the `nameUnamedGlobals` will use a name for the
global that is invalid ptx occurs. For non-extern globals, this is later
fixed by running the `NVPTXAssignValidGlobalNames` pass. However, It
makes sure to not touch externs as changing the name of "traditional
externs" will cause linking issues down the road.
This MR treats `.extern .shared` in the same manner as non-extern
globals during `NVPTXAssignValidGlobalNames` to fix the invalid names
given by `nameUnamedGlobals`.

[mlir][Interfaces] Add generic pattern for region inlining (#176641)
Add a new canonicalization pattern that inlines the body of acyclic
`RegionBranchOpInterface` ops. This pattern is a generalization and
replacement for the following existing patterns:
* `SingleBlockExecuteInliner`: inlines `scf.execute_region` ops with a
single block.
* `SimplifyTrivialLoops`: inlines / folds away `scf.for` ops with 0 or 1
iterations.
* `RemoveStaticCondition`: inlines `scf.if` ops with a static condition.
* `FoldConstantCase`: inlines `scf.index_switch` ops with a constant
operand.
Additionally, this new pattern is also enabled for `scf.while` ops.
Loops with `scf.condition(%false)` are now also inlined. (New test case
added.)
The new pattern looks for region branch ops with a single acyclic path
through the operation (starting from and ending at "parent"). All
regions on that path can be inlined into the enclosing block.
Depends on #177116.

[flang][cuda] Add support for derived-type component with managed/unified attributes (#177409)
Derived-type components that have the `ALLOCATABLE` or `POINTER`
attribute as well as the CUDA `MANAGED` or `UNIFIED` attribute need to
have a specific allocator index set in the descriptor so the allocation
is done correctly. Without this, the allocation is done in host memory
and will trigger illegal read or write if the component is used on the
device. The correct allocator index was set some time ago for the
`DEVICE` attribute but the `MANAGED` and `UNIFIED` attribute need the
same mechanism.
Since the `Component::Genre` has quite some room I opted to add specific
genre for allocatable and pointer with both managed or unified
attribute.
@klausler Let me know if you would prefer another solution. I was
thinking about a separate field but I wanted to avoid wasting some
bytes.

optimize it a bit further, i.e., propagate the uses of each phi node with
its incoming value and optimize away the phis. Deleted `fixPHINodes()`
too because the phis are already optimized away and there is no point
processing `fixPHINodes()`.

Peek through input shuffle operands and see if we can access the shuffle
source directly with an adjusted PCLMULQDQ mask bit
REAPPLIED after #176932 was reverted due to use of
is128BitLaneRepeatedShuffleMask instead of isRepeatedTargetShuffleMask
caused failures with SM_SentinalZero shuffle mask indices - regression
test added by #177414

[CAS] Introduce CASNodeSchema and NamedValuesSchema (#177058)
Introduce CASNodeSchema, which is the common base class for
building a schema that can be used to represent an object
inside CAS. The schema describes the ways to encode and decode
between CAS objects and their representative objects.
NamedValuesSchema is a basic schema that describes a sorted
list of named nodes, where each node is an object. The names are
stored in the root object, allowing users to decide whether to
load the objects based on their names.

This is a fix for https://github.com/llvm/llvm-project/issues/61636.
Ravi had this implemented downstream before he retired. This PR is a
chery-pick of that.
The test is taken from @jdoerfert's WIP change in
https://github.com/jdoerfert/llvm-project/commit/527bf4b1293f452aac1f872c4f771c7950b911f9.
The change partially undoes the changes done in
0caf736d7e1d16d1059553fc28dbac31f0b9f788, so @alexey-bataev might need
to take a look.

in both C++17 and C++20.
This also reverts the change in PR #177421, which is not needed
when cpp::is_integral_v<char8_t> works correctly in all modes.

[LLDB] Add a setting to simulate variables with missing locations (#177279)
Writing testcases for error handling that depends on specific DWARF is
very difficult and the resulting tests tend not to be very portable.
This patch adds a new setting to inject an error into variable
materialization, thus making it possible to write very simple source
code based tests for error handling instead.
This is primarily motivated by the Swift language plugin, but
functionality is generic and should be useful for other languages as
well.

[AArch64] Add test coverage for roundeven + float-to-int conversions (#173515)
Split off from https://github.com/llvm/llvm-project/pull/170018, which
was becoming a bit of a rats' nest.
This PR:
- Cleans up the `arm64-cvt-simd-fptoi.ll`, `round-conv.ll`,
`round-fptosi-sat-scalar.ll`, and `round-fptoui-sat-scalar.ll`
regression tests, removing `nounwind readnone` annotations from the
rounding function calls. These were changed in #171288 to be LLVM
intrinsics instead of libcalls, so we no longer need to annotate them in
order for them to be compiled to native instructions. I've also removed
the declaration blocks at the end of the files, since they're no longer
necessary.
- Adds `roundeven` tests to the 4 regression tests mentioned above, to
go along with the other rounding functions currently tested.
- Changes `round-conv.ll` to have autogenerated CHECK lines/assertions,
so it's simpler to update.
- Checks with GlobalISel as well in `round-conv.ll`,
`round-fptosi-sat-scalar.ll`, and `round-fptoui-sat-scalar.ll`. The
generated code is identical in `round-conv.ll`, but not yet as good in
the latter two.
The supporting changes are necessary here and would be difficult to
split off for little gain.

handleVectorComparePackedIntrinsic() can currently handle x86 and Arm

number of operands, and also that the 3rd operand in x86 vector

[AArch64] Stop using TargetFlags as RegState for LOADgot (#177411)
The register state flags have been represented using `unsigned`, but we
intend to make this an `enum class` in llvm/llvm-project#177090.
That change has shown there is some strange behaviour in this AArch64
function, which uses operand TargetFlags (usually used for representing
some abstract form of relocation information to clarify global accesses,
also represented with `unsigned`) to initialise the register state flags
(used for representing how the register operand is used by an
instruction). These TargetFlags are always 0 in the tests, so remove the
variable and assignment.

[LangRef] Clarify semantics of undef in shufflevector masks (#171453)
The current phrasing of `shufflevector` in the language reference
states:
> A poison element in the mask vector specifies that the resulting
element is poison. For backwards-compatibility reasons, LLVM temporarily
also accepts undef mask elements, which will be interpreted the same way
as poison elements.
This is a bit ambiguous. Does it mean that an undef mask element
produces a poison result element, or an undef result element?
Per https://reviews.llvm.org/D148637, the answer is the former. I've
updated the docs to make this explicit.
As part of the same paragraph, the language reference also currently
states:
> If the shuffle mask selects an undef element from one of the input
vectors, the resulting element is undef.
When I first skimmed this, I thought it meant that an undef *mask
element* resulted in an undef result element. However, it's actually
talking about undef *input elements*. That's easy to miss, since the
rest of the paragraph discusses mask elements. I've moved that sentence
to its own paragraph to make things less confusing.

[RISCV] Improve vector pseudo table's experiences on translating between two different pseudo opcodes. NFC (#177232)
Sometimes we might need to translate from one vector pseudo -- like
`PseudoVFMUL_ALT_VV_M8_E16` -- to its `VFSUB_VV` counterpart, namely
`PseudoVFSUB_ALT_VV_M8_E16`. It's difficult to do this efficiently with
the current vector pseudo search table infrastructure. So I propose two
changes in this patch:
1. Currently both `RISCVVInversePseudosTable` and `RISCVVPseudosTable`
does not distinguish between F16 and BF16. This will be problematic
during lookup -- especially for `RISCVVInversePseudosTable`. So I added
a new single-bit field `IsAltFmt` into both tables.
2. It'd be great for `RISCVVPseudosTable` to return not just the base
instruction opcode but also LMUL & SEW (if there is any). Because the
alternative will require multiple additional steps (e.g. calling
`getLMul(TSFlags)`) -- especially for the SEW-specific pseudos -- that
are not really ergonomic. So I added `VLMul`, `SEW`, and `IsAltFmt` to
the result of `RISCVVPseudosTable::getPseudoInfo`. The downside of this
is of course bloating the table size, which is why I tried to mitigate
it with using bit fields.
This should be a NFC

[orc-rt] Fix some Session::shutdown bugs. (#177528)
All calls to Session::shutdown were enquing their on-shutdown-complete
callbacks in Session's ShutdownInfo struct, but this queue is only
drained once by the thread that initiates shutdown. After the queue is
drained, subsequent calls to Session::shutdown were enquing their
callbacks in a queue that would never be drained.
This patch updates Session::shutdown to check whether shutdown has
completed already and, if so, run the on-shutdown-complete immediately.
This patch also fixes a concurrency bug: Session::shutdownComplete was
accessing SI->OnCompletes outside the session mutex, but this could lead
to corruption of SI->OnCompletes if a concurrent call to
Session::shutdown tried to enqueue a new callback to SI->OnCompletes
concurrently. This has been fixed by moving the SI->OnCompletes queue to
a new variable under the Session mutex, then draining the new queue
outside the mutex. (No testcase yet: this was discovered by observation,
and replicating the bug would depend on timing).

[lldb] Improve error message when we can't save core (#177496)
When you specify a filename to `process save core`, we'll write it in
the current working directory. In Xcode the CWD is `/` and you can't
generally write there.
```
(lldb) process save-core --style full foo
error: failed to save core file for process: Read-only file system
```
This PR improves the error message by including the output file when we
can't save core. However, just printing the filename isn't that much
more helpful, because FileSystem::Resolve only makes a path absolute if
it exists.
```
error: failed to save core file for process to 'foo': Read-only file system
```
Therefore I also modified the interface to add a flag to force resolve a
potentially non-exist path.
```
error: failed to save core file for process to '/foo': Read-only file system

[LV] Separate runtime check cost from total overhead in profitability check (#176754)
In isOutsideLoopWorkProfitable function, there are two places where only
the runtime check cost (RtC) should be used, but incorrectly included
the costs of middle blocks and early-exit blocks.
1. VectorizeMemoryCheckThreshold comparison for interleaving-only
2. Minimum trip count that bounds runtime check overhead, i.e. MinTC2
calculation
This results in an overly conservative minimum profitable trip count.
This patch separates the runtime check cost from the total overhead
cost, and uses only RtC for VectorizeMemoryCheckThreshold comparison and
the MinTC2 calculation.

The current interpreter does _not_ evaluate function calls when checking
for a potential constant expression.
However, it _does_ evaluate the initializers of constructors. In the
bytecode interpreter, this is harder because we compile the initializers
and the body of a constructor all in the same function.
Add a special opcode that we emit after the constructor initializers and
that aborts when we're checking for a potential constant expression.

errors.
This patch replaces all uses of the original printf call with a 0 value

[NFC][MI] Tidy Up RegState enum use (2/2) (#177090)
This Change makes `RegState` into an enum class, with bitwise operators.
It also:
- Updates declarations of flag variables/arguments/returns from
`unsigned` to `RegState`.
- Updates empty RegState initializers from 0 to `{}`.
If this is causing problems in downstream code:
- Adopt the `RegState getXXXRegState(bool)` functions instead of using a
ternary operator such as `bool ? RegState::XXX : 0`.
- Adopt the `bool hasRegState(RegState, RegState)` function instead of
using a bitwise check of the flags.

[MC][X86/M68k] Emit syntax directive for AT&T (#167234)
This eases interoperability by making it explicit in emitted assembly code which syntax is used.
Refactored to remove X86-specific directives and logic from the generic MC(Asm)Streamer.
Motivated by building LLVM with `-mllvm -x86-asm-syntax=intel` (i.e. a global preference for Intel
syntax). A Bolt test (`runtime/X86/fdata-escape-chars.ll`) was using `llc` to compile to assembly
and then assembling with `clang`. The specific option causes Clang to assume Intel syntax but only
for assembly and not inline assembly.

[NFCI][bolt][test] Enable AT&T syntax generally (#172355)
Having it in the X86 subdirectory only affects tests in that directory.
That's however not sufficient as for example runtime/X86/pie-exceptions-split.test is affected but
isn't located in the X86 directory.
This essentially fixes the fix for the original commit by guarding it properly for when the X86
target has been built and the flag is recognized.

[Clang] Fix the normalization of fold constraints (#177531)
Fold constraints can contain packs expanded from different locations.
For `C<Ps...>`, where the ellipsis immediately follows the argument, the
pack should be expanded in place regardless of the fold expression. For
`C<Ps> && ...`, the fold expression itself is responsible for expanding
Ps.
Previously, both kinds of packs were expanded by the fold expression,
which broke assumptions within concept caching. This patch fixes that by
preserving PackExpansionTypes for the first kind of pack while rewriting
them to non-packs for the second kind.
This patch also removes an unused function and performs some cleanup of
the evaluation contexts. Hopefully it is viable for backporting.
No release note, as this issue was a regression.

[mlir][spirv] Add Conv operations for TOSA Extended Instruction Set (001000.1) (#176908)
This patch expands support for the TOSA Extended Instruction Set
(001000.1) to the SPIR-V dialect in MLIR. The TOSA extended instruction
set provides a standardized set of machine learning operations designed
to be used within `spirv.ARM.Graph` operations (corresponding to
OpGraphARM in SPV_ARM_graph) and typed with `!spirv.arm.tensor<...>`
(corresponding to OpTypeTensorARM in SPV_ARM_tensor).
The change introduces:
* Extending dialect plumbing for import, serialization, and
deserialization of the TOSA extended instruction set.
* The `spirv.Tosa.*Conv*` convolution operation from TOSA extended
instruction, each lowering to the corresponding `OpExtInst`.
* Verification enforcing that new convolution operations appears only
within `spirv.ARM.Graph` regions, operates on `!spirv.arm.tensor<...>`
types, and is well-formed according to the TOSA 001000.1 specification.
All convolution operations from TOSA 001000.1 extended instructions are
introduced: [parser, printer, verifier, and round-trip tests using
MLIR’s SPIR-V serialization/deserialization infrastructure are included.
This work aligns with Khronos SPIR-V TOSA specifications.

[ml_program] fix bufferizesToMemoryRead for ml_program.global_store (#177387)
This is a fix for the `BufferizableOpInterface` implementation for
`ml_program.global_store`.
`bufferizesToMemoryRead` currently returns false for
`GlobalStoreOpInterface`, but I believe it should return true as
`ml_program.global_store` needs to read its input buffer to know what
value to store to global.
This manifested in a bug where `one-shot-bufferize` would produce MLIR
that copies uninitialized data to the global var instead of the intended
value to be stored.
For the following MLIR:
```
module {
ml_program.global private mutable @"state_tensor"(dense<0.0> : tensor<4x75xf32>) : tensor<4x75xf32>
func.func @main() -> tensor<4x75xf32> {
%c0 = arith.constant 0 : index
%cst_val = arith.constant 1.0 : f32
%initial_state = ml_program.global_load @"state_tensor" : tensor<4x75xf32>
%val = tensor.extract %initial_state[%c0, %c0] : tensor<4x75xf32>
%next_val = arith.addf %val, %cst_val : f32
%updated_tensor = tensor.insert %next_val into %initial_state[%c0, %c0] : tensor<4x75xf32>
ml_program.global_store @"state_tensor" = %updated_tensor : tensor<4x75xf32>
return %updated_tensor : tensor<4x75xf32>
}
}
```
`one-shot-bufferize` produces this incorrect MLIR
```
module {
memref.global "private" @state_tensor : memref<4x75xf32> = dense<0.000000e+00>
func.func @main() -> tensor<4x75xf32> {
%c0 = arith.constant 0 : index
%cst = arith.constant 1.000000e+00 : f32
%0 = memref.get_global @state_tensor : memref<4x75xf32>
%1 = memref.load %0[%c0, %c0] : memref<4x75xf32>
%2 = arith.addf %1, %cst : f32
%alloc = memref.alloc() {alignment = 64 : i64} : memref<4x75xf32>

%3 = bufferization.to_tensor %alloc : memref<4x75xf32> to tensor<4x75xf32>
%alloc_0 = memref.alloc() {alignment = 64 : i64} : memref<4x75xf32>
%4 = memref.get_global @state_tensor : memref<4x75xf32>
memref.copy %alloc_0, %4 : memref<4x75xf32> to memref<4x75xf32>
return %3 : tensor<4x75xf32>
}
}
```
Note that `memref.copy` at the end copies an uninitialized `alloc_0` to
the global variable.
But after the change we see the following MLIR:
```
module {
memref.global "private" @state_tensor : memref<4x75xf32> = dense<0.000000e+00>
func.func @main() -> tensor<4x75xf32> {
%c0 = arith.constant 0 : index
%cst = arith.constant 1.000000e+00 : f32
%0 = memref.get_global @state_tensor : memref<4x75xf32>
%1 = memref.load %0[%c0, %c0] : memref<4x75xf32>
%2 = arith.addf %1, %cst : f32
%alloc = memref.alloc() {alignment = 64 : i64} : memref<4x75xf32>
memref.copy %0, %alloc : memref<4x75xf32> to memref<4x75xf32>
memref.store %2, %alloc[%c0, %c0] : memref<4x75xf32>
%3 = bufferization.to_tensor %alloc : memref<4x75xf32> to tensor<4x75xf32>
%alloc_0 = memref.alloc() {alignment = 64 : i64} : memref<4x75xf32>
memref.copy %alloc, %alloc_0 : memref<4x75xf32> to memref<4x75xf32>
%4 = memref.get_global @state_tensor : memref<4x75xf32>
memref.copy %alloc_0, %4 : memref<4x75xf32> to memref<4x75xf32>
return %3 : tensor<4x75xf32>
}
}
```
We now see that the relevant data is copied to `alloc_0` before it is
stored in global.

[mlir][linalg] Update createWriteOrMaskedWrite (#174810)
`createWriteOrMaskedWrite` is used extensively in the Linalg vectorizer.
When a write uses non-zero indices, the helper currently computes mask
sizes as if the write started at 0 (`size = dim(d)`), which can produce
incorrect `vector.create_mask` operands for the generated
`vector.transfer_write`. Instead, the mask size should be computed as
`size = dim(d) - write_index(d)`.
EXAMPLE
-------
Let`s use this example to illustrate:
```mlir
%res = tensor.insert_slice
%src into %dest[0, %c2] [5, 1] [1, 1] : tensor<5x1xi32> into tensor<?x3xi32>
```
This op is vectorized as a pair of `vector.transfer_read` +
`vector.transfer_write` ops. When calculating the mask for the
vector.transfer_write operation, the write indices should be taken into
account (*):
```mlir
%dim = tensor.dim %dest, %c_0 : tensor<?x3xi32>
// Subtract dim-0 and idx-0
%mask_size_0 = arith.subi %dim, %c0 : index
%x3 = arith.constant 3 : index
// Subtract dim-1 and idx-1
%mask_size_1 = arith.subi %c3, %c2 : index
%mask = vector.create_mask %mask_size_0, %mask_size_1 : vector<8x1xi1>
```
Currently, the mask is incorrectly computed as:
```mlir
%dim = tensor.dim %dest, %c_0 : tensor<?x3xi32>
%mask = vector.create_mask %dim, %c3 : vector<8x1xi1>
```
This PR fixes that.

[mlir] Add side-effect check to moveOperationDependencies (#176361)
This patch adds a side-effect check to `moveOperationDependencies` to
match the behavior of `moveValueDefinitions`. Previously,
`moveOperationDependencies` would move operations with side-effecting
dependencies, which could change program semantics.
**Note** that the existing test changes are needed because unregistered
operations (e.g., "moved_op"()) are treated as side-effecting. These
tests were updated to use pure operations for operations in the moved
slice, while keeping unregistered ops for operations that aren't moved
(e.g., "before"(), "foo"()). This ensures that tests continue to
exercise their intended functionality without being blocked by the new
side-effect check.

[LangRef] Clarify specification for float min/max operations (#172012)
This implements some clarifications for the specification of floating
point min/max operations based on the discussion in
https://discourse.llvm.org/t/rfc-a-consistent-set-of-semantics-for-the-floating-point-minimum-and-maximum-operations/89006.
The key changes are:
* Explicitly specify minnum and maxnum with an sNaN operand as
non-deterministically either returning NaN or treating sNaN as qNaN.
This was implied by our general NaN semantics, but is important to call
out here due to the special behavior of sNaN.
* Explicitly specify the same non-determinism for the minnum/maxnum
based vector reductions as well.
* Explicitly specify the meaning of nsz on float min/max ops. In
particular, clarify that unlike normal nsz semantics, it does not allow
introducing a zero with a different sign out of thin air.
* Simplify the semantics comparison section. This now focuses only on
NaN and signed zero behavior, but omits information about exceptions
that is not relevant for these non-constrained intrinsics.

[VectorCombine] Fold vector sign-bit checks (#175194)
Fold patterns that extract sign bits, reduce them, and compare against
boundary values into direct sign checks on the reduced vector.
```
icmp pred (reduce.{add,or,and,umax,umin}(lshr X, BitWidth-1)), C
-> icmp slt/sgt (reduce.{or,umax,and,umin}(X)), 0/-1
```
When the comparison is against 0 or MAX (1 for boolean reductions,
NumElts for add), the pattern reduces to one of four quantified
predicates:
- ∀x: x < 0 (AllNeg)
- ∀x: x ≥ 0 (AllNonNeg)
- ∃x: x < 0 (AnyNeg)
- ∃x: x ≥ 0 (AnyNonNeg)
The transform eliminates the shift and selects between
reduce.or/reduce.umax or reduce.and/reduce.umin based on cost modeling.

[mlir][Utils] Add verifyElementTypesMatch helper (NFC) (#176668)
This change builds on #174336 and #175880, which introduced shared
VerificationUtils with verifyDynamicDimensionCount() and
verifyRanksMatch() methods.
This patch adds a new verifyElementTypesMatch() verification utility
that checks if two shaped types have matching element types and emits
consistent error messages. The utility is applied to several ops across
the MemRef and Vector dialects.

[PowerPC] Fix instruction sizes / branch relaxation (#175556)
For PowerPC, having accurate (or at least not too small) instruction
sizes is critical, because the PPCBranchSelector pass relies on them.
Underestimating the size of an instruction can result in the wrong
branch kind being chosen, which will result in an MC error.
This patch introduces validation that the instruction size reported by
TII matches the actually emitted instruction size, and fixes various
cases where this was not the case.
Fixes https://github.com/llvm/llvm-project/issues/175190.

[Github] Add initial workflow to prune unused user branches
This patch starts implementing the long requested feature of a workflow
to automatically prune user branches that are not tied to a PR. For now
this just consists of a script that finds user branches not attached to
a PR and prints them out. Future patches will add support for dumping
the diff between the branches and main (to persist to artifact storage
so people can recover if they intended to use the branch) and actually
deleting the branches.

[lldb] Unconditionally setup posix spawn responsible flag (#177451)
# Problem
The TCC support in LLDB was added by
https://github.com/llvm/llvm-project/commit/041c7b84a4b925476d1e21ed302786033bb6035f.
However, on newer macOS machines, when launching and debugging an
Catalyst app on macOS (see
[Host.mm](https://github.com/llvm/llvm-project/blob/1286de408cc4a3ba1bd6cb6fed7d9517c0429462/lldb/source/Host/macosx/objcxx/Host.mm#L1208-L1219)),
the TCC doesn't work as expected. This is because, even though the
launch info doesn't specify `eLaunchFlagInheritTCCFromParent`, the app
is still launched to inherit TCC from its parent (the LLDB). This
prevents the user from granting privacy access to the Catalyst app,
which is usually reflected in macOS' "Privacy & Security" settings.
For example, in the following screenshot (see PR), even when the microphone
access has already been granted to WhatsApp, trying to use it will still
cause a prompt (as if it's not granted already).
# Fix
On newer macOS versions, the code which was originally inside the `#if
__has_include(<responsibility.h>)` actually works. So the fix is to
unwrap them from the `#if`.
Also, since we already forward declare the type and dlsym the symbol,
the `#include <responsibility.h>` can be removed. Same for the
`@available` check, since the original code handles `dlsym` failure.
See test and screenshots in PR.

[SPIR-V] Implement sample and sample_clamp intrinsics for HLSL resources (#177234)
This patch implements the `sample` and `sample_clamp` intrinsics for
HLSL
resources in the SPIR-V backend. It adds the necessary intrinsic
definitions
in `IntrinsicsDirectX.td` and `IntrinsicsSPIRV.td`, and implements the
instruction selection logic in `SPIRVInstructionSelector.cpp`.
Key changes:
- Added `int_dx_resource_sample` and `int_dx_resource_sample_clamp`
intrinsics.
- Added `int_spv_resource_sample` and `int_spv_resource_sample_clamp`
intrinsics.
- Implemented `selectSampleIntrinsic` to handle
`OpImageSampleImplicitLod` generation.
- Added `ResourceDimension` enum in `DXILABI.h` and `HLSLResource.h`.
- Added a new test case
`llvm/test/CodeGen/SPIRV/hlsl-resources/Sample.ll` to verify the
implementation.

[profcheck] Fix profle metatdata propagation for Large Integer operations (#175862)
This PR improves the propagation of profile metadata within the
ExpandIRInsts pass. When lowering large integer division operations, the
pass now ensures that branch weights are correctly attached to the
generated control flow, preventing the loss of profile data during IR
expansion.
This PR improves signed and unsigned division/remainder for non-native
bit widths (e.g., `sdiv/udiv i129`, `srem/urem i129`) and implemented
Heuristic-Based Branch Weights labeling using established heuristics for
edge cases e.g., `Division-by-zero guards` and `Magnitude comparisons
between dividends and divisors`.
It also adds detailed comments within the expansion logic to explain the
rationale behind specific branch weight choices and the underlying
mathematical invariants.
Please refer to the implementation details in the source code for the
specific branch weight values and the logic governing their application.

[HIP] Pass HIP library directly and refactor (#176019)
Summary:
Currently we pass `-L` and `-l` to get the HIP library. Because we are
attached to a single HIP installation it's far better to pass it by
filename. This is because the `-L` could be out of order with other user
libraries and those could override it. If someone uses HIP with a
specific ROCm installation they most likely want that library, otherwise
incompatibilities can occur. This is still overridable with command line
flags if users want to pass a different one for some reason.
This PR also refactors the handling to be more generic for future
additions.

[Support] Avoid misguided FreeBSD hack (#177508)
FreeBSD doesn't do anything wrong here, it just happens to define and
use a struct thread in its own headers. The problems arise because here
in LLVM we have using namespace llvm prior to including system headers,
which is bad practice for precisely this reason. If we instead play by
the rules and defer our using namespace llvm until after we've included
the system headers then we no longer need this hack.
This hack is particularly problematic by being conditional on
__FreeBSD__ as of 9093ba9f7ee5 ("[Support] Include Support/thread.h
before api implementations (#111175)"), since on non-FreeBSD
Threading.inc can reference anything in Support/thread.h, only causing
errors on FreeBSD, which is precisely what happened in 64be34c562a2
("Enable using threads on z/OS (#171847)").
By deferring the using namespace llvm until after Threading.inc is
included there may be build failures introduced on untested platforms
due to needing to replace unqualified identifiers with qualified ones by
prepending llvm::.

[SystemZ][z/OS] Implement #pragma export (#141671)
Implement the export pragma that is used in the z/OS XL C/C++ compiler
to indicate that an external symbol is to be exported from the shared
library. The syntax for the pragma is:
```
'#pragma' 'export' '(' name ')'
```
For C++ if `name` is a function it needs to be declared `extern "C"`.
See the following for the XL documentation:
- https://www.ibm.com/docs/en/zos/3.1.0?topic=descriptions-pragma-export
This code was originally in PR
https://github.com/llvm/llvm-project/pull/111035. I have split it out
into separate PRs so the code for #pragma export is in one PR and the
code for _Export keyword is in another. See that original PR for earlier
comments.

[scudo] Add flags to secondary cache entries. (#177506)
Instead of setting a cache entry back to read-write based on whether MTE
is enabled, add a flag that indicates if this entry was made
inaccessible. On Android, we have seen strange crashes were MTE is
disabled for a process, but the cache entry is inaccessible, causing an
access error. This indicates MTE was enabled at some point, then
disabled again. There is likely some race, or method to disable without
making inaccessible entries read-writable again. Adding the flags should
avoid this happening in the future.
Remove the resetting of the secondary cache entries when disabling MTE
since it can be done as necessary.
This change will also allow us to always make the secondary cache
entries inaccessible in the future to increase security measures even
when MTE is not enabled.
Current unit tests already cover this change.

[Flang][OpenMP][MLIR] Align declare mapper pass handling with other map and global operations (#176852)
This PR makes a couple of minor tweaks to the lowering for
declare_mapper operations:
1) Add declare_mapper operations to the list of global operations to
have optimisation passes
executed on them. Primarily just to make sure we keep it inline with
other global operations
that contain regions. Prevents oddities where we embed FIR/HLFIR into
the mapper that needs
lowered before being converted to LLVM-IR. One example that springs to
mind is if we ever
decide to remove the single block condition on the operation to allow
conditional checks
for mapped data.
2) Add a CodeGenOpenMP.cpp conversion for DeclareMapperOp to make sure
we convert the return
type correctly from a BoxType to a struct type rather than an opaque
pointer when lowering.
Currently, I've left out the block argument types from being converted
as they're wrapped
in a fir.ref and would be opauqe pointers in either case.
So some minor additions to keep declare_mapper a little more inline with
the rest of the OpenMP operations.

This was causing failures in release-mode builds because the
GetPointerBaseWithConstantOffset call would never be run which leads to
ValueOffset being uninitialized and thus the behavior of the function is
unpredictable.

[lldb] Add a GetSubsetExtractorSP method to DataExtractor (#177309)
We have many places where an ObjectFile subclass will take the
DataExtractor representing the entire binary, create a subsection of
that in a new DataExtractor for processing. For instance, an object file
might have symbol table entries with offsets into the string table. A
common code pattern is to create a DataExtractor representing the string
table, and then pulling out the c-strings based on those offsets from
the string table DataExtractor.
When code does this, it creates a new DataExtractor, copies the
Endianness and Wordsize from the original, copies the DataBufferSP from
the original, and specifies a new start and offset into the DataBuffer.
However, if the binary is actaully stored in a VirtualDataExtractor,
this code pattern loses the correct virtual-to-physical table
translation and will not work correctly. This new method simplifies this
common pattern, and correctly takes a subset of a VirtualDataExtractor.
The current implementation only allows a subset of a
VirtualDataExtractor that is contained within a single virtual entry
(LookupTable entry) and returns a DataExtractor with the corret offsets
calculated from the LookupTable. If we need to a VirtualDataExtractor to
create a Subset DataExtractor representing multiple separate virtual
ranges of data, we'll need to copy over the LookupTable entries that
cover all the bytes, and update them to be relative to the new
VirtualDataExtractor. It's a bit of work, and it's not needed right now,
so I'm not tackling that.
I am working on a larger PR which needs this new method. This PR
contains a unit test that uses it.

[lldb] Fix setting CanJIT if memory cannot be allocated (#176099)
When a server is unable to allocate memory for the `_M` packet, it may
respond with an error code. In this case,
`GDBRemoteCommunicationClient::AllocateMemory()` sets
`m_supports_alloc_dealloc_memory` to `eLazyBoolYes`; `eLazyBoolNo` is
only used if the server cannot handle the packet at all. Before this
patch, `ProcessGDBRemote::DoAllocateMemory()` checked this flag and
returned `LLDB_INVALID_ADDRESS` without setting an error, which caused
`Process::CanJIT()` to set `m_can_jit = eCanJITYes`, resulting in
`IRMemoryMap::FindSpace()` attempting to allocate memory in the inferior
process and failing. With the patch,
`ProcessGDBRemote::DoAllocateMemory()` returns an error and `m_can_jit`
is set to `eCanJITNo`.
Example debug session:
```
(lldb) platform connect...
(lldb) file test
(lldb) br set...
(lldb) run
Process 100 launched:...
Process 100 stopped

[LV] capture branch weights for constant trip counts (#175096)
When a vectorized loop has constant trip, it's important to update the
profile information accordingly. Hotness analysis will only look at
profile info.
For example, in the `tripcount.ll` test, without producing the profile
info, in the `const_trip_over_profile` function, the BFI of the
`vector.body` would be 32 (this is the expected value when synthetic
branch weights are used, in loops). The real value is 250. The
`for.body`value was _very_ incorrect before, too (and detrimentally so,
as it would have appeared as "very hot" when it wasn't):
The table below was obtained by printing BFI in the RUN: command, i.e.
`build/bin/opt < llvm/test/Transforms/LoopVectorize/tripcount.ll
-passes="loop-vectorize,print<block-freq>"
-loop-vectorize-with-block-frequency -S -o /dev/null`. Showing only the
`float` value, i.e. the BFI relative to the function entry BB.
```
Printing analysis results of BFI for function 'const_trip_over_profile':
block-frequency-info: const_trip_over_profile

[libc++] Automatically detect the libc++ hardening mode from the test suite (#172505)
This prevents hardcoding the hardening mode via compiler flags, and
allows testing what the default hardening mode is on platforms that set
it to something that isn't `none`. Otherwise, a platform setting a
default (which is done via -DLIBCXX_HARDENING_MODE=mode at CMake
configuration time) would end up passing `-D_LIBCPP_HARDENING_MODE=mode`
to the compiler, which does not allow checking what the default mode is.

[flang] Support cuf.device_address in FIR AliasAnalysis. (#177518)
Support `cuf.device_address` same way as `fir.address_of`.
This implementation implies that the host address and the device
address `MustAlias` (as shown in the new test). This should be
conservatively correct as long as `MustAlias` does not allow
to assume that the actual addresses are the same (that is what
LLVM documentation implies, I believe).
It is probably worth adding an operation interface to handle
`fir::AddrOfOp` and `cuf::DeviceAddressOp` in FIR AliasAnalysis,
but for the initial implementation I hardcoded the checks.
I also removed the call to `fir::valueHasFirAttribute` that performs
on demand SymbolTable lookups, which may be costly, and added
SymbolTable caching in FIR AliasAnalysis object. Anyway,
`fir::valueHasFirAttribute` does not work for `cuf::DeviceAddressOp`.

This patch implements `ConditionallySpeculatable` interface for some
FIR operations (`embox`, `rebox`, `box_addr`, `box_dims` and `convert`).
It also adds `Pure` trait for `fir.shape`, `fir.shapeshift`,
`fir.shift` and `fir.slice`.
I could have split this into multiple patches, but the changes
are better tested together on real apps, and the amount of affected
code is small.
There are more `NoMemoryEffect` operations for which I am planning
to do the same in future PRs.

[AMDGPU][GFX1250] Optimize s_wait_xcnt for back-to-back atomic RMWs (#177620)
This patch optimizes the insertion of s_wait_xcnt instruction for
sequences of atomic read-modify-write (RMW) operations in the
SIInsertWaitcnts pass. The Memory Legalizer conservatively inserts a
soft xcnt instruction before each atomic RMW operation as part of PR
168852, which is correct given the nature of atomic operations.
However, for back-to-back atomic RMWs, only the first s_wait_xcnt is
necessary for better runtime performance. This patch tracks atomic
RMW blocks within each basic block and removes redundant soft xcnt
instructions, keeping only the first wait in each sequence. An atomic
RMW block continues through subsequent atomic RMWs and non-memory
instructions (e.g., ALU operations) but is broken by CU-scoped memory
operations, atomic stores, or basic block boundaries.

[lldb] Fix data buffer regression in ObjectFile (#177724)
This fixes a regression in `ObjectFile` and `ObjectFileELF` introduced
by #171574.
The original code created a `DataBuffer` using `MapFileDataWritable`.
```
data_sp = MapFileDataWritable(*file, length, file_offset);
if (!data_sp)
return nullptr;
data_offset = 0;
```
The new code requires converting the `DataBuffer` to a `DataExtractor`:
```
DataBufferSP buffer_sp = MapFileDataWritable(*file, length, file_offset);
if (!buffer_sp)
return nullptr;
extractor_sp = std::make_shared<DataExtractor>();
extractor_sp->SetData(buffer_sp, data_offset, buffer_sp->GetByteSize());
data_offset = 0;
```
The issue is that once we get a data buffer back from
MapFileDataWritable, we don't have to adjust for the `data_offset` again
when calling `SetData` as the `DataBuffer` is already normalized to have
a zero start offset. A similar issue exists in `ObjectFile`.

[ELF] Set vna_flags to VER_FLG_WEAK if all references are weak (#176673)
When all undefined references to a version are weak, set vna_flags to
VER_FLG_WEAK in the .gnu.version_r section. This enables glibc ld.so to
report a warning instead of an error when the required version is not
found at runtime, supporting optional dependencies.
Per https://sourceware.org/bugzilla/show_bug.cgi?id=24718#c20 ,
glibc rtld since 2.30 (BZ #24741) tolerates missing versioned symbols
when the runtime shared object defines the required version. With this
vna_flags VER_FLG_WEAK change, rtld can also tolerate a completely
missing version, printing a message like:
```
% LD_PRELOAD=c2.so ./a
./a: /tmp/t/v2/c2.so: weak version `v1' not found (required by /tmp/t/v2/b.so)
a
```
instead of a fatal error.
In addition, add a comment about `vn.vernaxus.size() == 1`.

[WebAssembly] Fix exception handling initialization order in TargetMachine constructor (#177542)
The WebAssemblyTargetMachine constructor had an ordering issue where
initAsmInfo() was called before basicCheckForEHAndSjLj(). This caused
problems in incremental compilation scenarios where:
1. `initAsmInfo()` sets `MCAsmInfo` exception type based on
`Options.ExceptionModel`
2. But `Options.ExceptionModel` might still be None at this point
3. `basicCheckForEHAndSjLj()` runs later and updates
`Options.ExceptionModel`
based on command-line flags like `-wasm-enable-eh`
4. `MCAsmInfo` retains the incorrect exception type (`None` instead of
`Wasm`)
5. This prevents WebAssembly exception handling passes from running
The fix swaps the order so basicCheckForEHAndSjLj() runs first to
establish the correct exception model before initAsmInfo() configures
MCAsmInfo based on that model.
This enables WebAssembly exception handling to work correctly in
clang-repl and other incremental compilation scenarios.

[test][NFC] Add more keys to test SDKSettings files (#177538)
Every time DarwinSDKInfo reads a new key out of SDKSettings, a boatload
of test SDKSettings files need to be updated across several repositories
and forks and branches. It’s tedious to be careful to update those with
real values so that the tests are properly regression testing older
SDKs. It’s important to be careful so that the tests are accurate, e.g.
to prevent the scenario where DarwinSDKInfo starts reading a new key out
of SDKSettings and assumes that it’s always available everywhere, when
in reality it was only added a few releases ago and will break with
older SDKs. If the test SDKSettings files continue to be updated ad hoc,
it’s going to be really easy to copy/paste a default value everywhere,
and then clients will see incorrect behaviors with the real SDKs, or
even compiler crashes if the key is unconditionally read. Preemptively
add all of the maybe-possibly-compiler relevant keys to the test
SDKSettings files from the real SDKs so that the test files are an
accurate representation and shouldn't need to be touched in the future.
Where the test SDKSettings have intentionally doctored data, add a
Comments key explaining what is changed from the real SDK, and alter the
SDK name with a tag indicating the change.

[InstCombine] Combine `select(C0, select(C1, b, a), b)` -> `select(C0&&!C1, a, b)` (#177410)
Fixes #82350
Address cases like:
```
select(C0, select(C1, b, a), b) -> select(C0&!C1, a, b)
select(C0, a, select(C1, b, a)) -> select(C0|!C1, a, b)
```
It seem that it generates better code for the real world examples for
the few targets I have checked: https://godbolt.org/z/KeEMd9b8E .
On the most generic case it generates the same assembly code for the
sources and targets for all targets, expect RISC-V, where the targets
seem shoretr and better (less branching):
https://godbolt.org/z/3has1Td5G So I did not experience any regression
on any target in no scenario.

[MLIR] Support dynamic traits in `DynamicDialect` (#177735)
Unlike Interfaces, Traits in MLIR are static: they are defined via CRTP
templates and used as base classes of an `Op`, which makes them
difficult to attach to an op dynamically.
However, in IRDL and the Python bindings, we define operations
dynamically through `DynamicDialect`, which means the traditional static
traits cannot be applied to them. Traits are important, for example,
they are how MLIR marks an op as a terminator or a non-terminator.
If `DynamicDialect` does not support traits, then even though we can
define an op with regions, we cannot define new terminators or mark an
op as a non-terminator. This makes `DynamicDialect` very limited in
region-related scenarios.
In this PR, we introduce a `DynamicOpTrait` type that “dynamizes”
`OpTrait`, enabling traits to be attached to ops in `DynamicDialect`.
The key design goal is that existing checks in the MLIR codebase such as
`op->hasTrait<XXX>()` work seamlessly on ops defined by
`DynamicOpDefinition`, without requiring any changes.
Note that currently only two traits `IsTerminator` and `NoTerminator`
are supported in this PR.
This PR aims to lay the groundwork for adding support for traits in IRDL
and python bindings (and maybe other bindings) in the future.
Related to #158066.

[InstCombine] Mark select in fdiv transforms with unknown profile (#177759)
As part of the profcheck effort we are trying to explicitly annotate
select instructions where we cannot reasonably synthesize profile
information as having an unknown profile. This does that for the case
introduced in 0993d69bc35cfdd4f3a904a603701e66906e8987.

[Polly] Update isl to isl-0.27 (#177776)
Fixes: #177527
Updated test cases:
* CodeGen/OpenMP/matmul-parallel.ll, ScheduleOptimizer/pattern-matching-based-opts.ll
Before the update, ISL bailed out the dependency computation due to
hitting the max operation limit. The commit
https://repo.or.cz/isl.git/commit/4bdfe2567715c5d1a8287c07d8685eb3db281e32
seems to have reduced the complexity needed of the dependency
computation, thus now being able to recognize some loops as parallel.
The tests were checking that the outer loop is not parallel, but some
inner loops can be parallized, particularly the array packing loops.
* DeLICM/reduction_looprotate_hoisted.ll
changes in how isl generates expressions
* ScheduleOptimizer/pattern-matching-based-opts_5.ll
changes in how isl generates expressions, and AST node changes

[MLIR][XeGPU] Preserve Leading dimension when blocking rank-sensitive operations (#177489)
This PR preserves leading dimensions for
xegpu.load_matrix/store_matrix/atomic_rmw/convert_layout, and vector
operations which have impact on shapes:
broadcast/multi-reduction/shape_cast/transpose.
Rank-sensitive operations are operations whose semantics depend on the
tensor rank (and consequently its shape), and therefore must not alter
the input tile rank or shape, such as by dropping leading dimensions.

[clang-tidy] Add llvm-use-vector-utils (#177722)
This new check suggests the following replacements:
* `llvm::to_vector(llvm::map_range(X, Fn))` -> `llvm::map_to_vector(X,
Fn)`
* `llvm::to_vector(llvm::make_filter_range(X, Fn))` ->
`llvm::filter_to_vector(X, Fn)`
and add the `SmallVectorExtras.h` include when necessary.
The check is called `vector-utils` because we may want to handle more
cases in the future, like turning explicit calls to SmallVector
constructor to `llvm::to_vector` (which lives in `SmallVector.h`, not
`SmallVectorExtras.h`).

[mlir][python] Support Arbitrary Precision Integers in MLIR C API and Python Bindings (#177733)
This PR extends the MLIR C API and Python bindings to support
**arbitrary-precision integers (`APInt`)**, overcoming the previous
limitation where `IntegerAttr` values were restricted to 64 bits.
Cryptographic applications often require integer types much larger than
standard machine words (e.g., the 256-bit modulus for the BN254 curve).
Previously, attempting to bind these values resulted in truncation or
errors. This PR exposes the underlying word-based `APInt` structure via
the C API and updates the Python bindings to seamlessly handle Python's
arbitrary-precision integers.

[MLIR][Python] Add a DSL for defining dialects in Python bindings (#169045)
Python bindings for the IRDL dialect were introduced in #158488. They
are currently usable—for constructing IR and dynamically loading modules
that contain `irdl.dialect` into MLIR. However, there are still several
pain points when working with them:
* The IRDL IR-building interface is not very intuitive and tends to be
quite verbose.
* We do not yet have the corresponding `OpView` classes for IRDL-defined
operations.
To address these issues, I propose creating a wrapper (effectively a
small “DSL”) on top of the existing IRDL Python bindings. This wrapper
aims to simplify IR construction and automatically generate the
corresponding `OpView` types. A simple example is shown below.
Currently, using the IRDL bindings looks like this:
```python
m = Module.create()
with InsertionPoint(m.body):
myint = irdl.dialect("myint")
with InsertionPoint(myint.body):
constant = irdl.operation_("constant")
with InsertionPoint(constant.body):
iattr = irdl.base(base_name="#builtin.integer")
i32 = irdl.is_(TypeAttr.get(IntegerType.get_signless(32)))
irdl.attributes_([iattr], ["value"])
irdl.results_([i32], ["cst"], [irdl.Variadicity.single])
add = irdl.operation_("add")
with InsertionPoint(add.body):
i32 = irdl.is_(TypeAttr.get(IntegerType.get_signless(32)))
irdl.operands_(
[i32, i32],
["lhs", "rhs"],
[irdl.Variadicity.single, irdl.Variadicity.single],
)
irdl.results_([i32], ["res"], [irdl.Variadicity.single])
irdl.load_dialects(m)
```
With the proposed DSL (module name `mlir.dialects.ext`), the equivalent
implementation becomes:
```python
class MyInt(Dialect, name="myint"):
pass
i32 = IntegerType[32]
class ConstantOp(MyInt.Operation, name="constant"):
value: IntegerAttr
cst: Result[i32]
class AddOp(MyInt.Operation, name="add"):
lhs: Operand[i32]
rhs: Operand[i32]
res: Result[i32]
MyInt.load()
```
Compared with the current IRDL Python bindings, this DSL mainly adds the
following:
* **A more intuitive interface** for constructing IRDL definitions (as
shown in the example).
* **Automatic generation of the corresponding `OpView`
classes**—including `__init__` methods and property getters for each
defined operation. Similar to TableGen’s `ins`, operands and attributes
can be interleaved in arbitrary order. Special handling is also
implemented for optional and variadic operands/results (such as
computing segment sizes) so that they feel as natural to use as native
operations.
* **Lazy insertion of ops**: all ops are created and inserted only when
`Dialect.load()` is called, which makes it unnecessary to specify an
MLIR context immediately when defining an IRDL dialect.
* **Basic type inference** in operation builders (i.e.
`OpViewCls.__init__`) for trivial result types.
The current DSL does not yet cover all IRDL operations. Several features
are not supported at the moment:
- Defining new types or attributes
- Parametric constraints
- Adding regions to operations

[MoveAutoInit] Fix for miscompilation for #150120 (#173961)
Fixes the miscompilation discussed for the PR #164882 as part of
generalizing the optimization for the issue #150120.
Without this commit, MoveAutoInit moves the store instruction to a
different branch which does not dominate the user dominator node. This
results in UB at runtime. The example in the test case is specifically
for an irreducible loop, in which all the predecessor may not dominate
user dominator head.
To fix this problem, we've introduced a new check to verify if the
predecessor of the user dominator node does in fact dominate user
dominator node before deciding that it is the node where the instruction
will be moved to.

[VectorCombine] Fold vector.reduce.OP(F(X)) == 0 -> OP(X) == 0 (#173069)
This commit introduces a pattern to do the following fold:
vector.reduce.OP f(X_i) == 0 -> vector.reduce.OP X_i == 0
In order to decide on this fold, we use the following properties:
1. OP X_i == 0 <=> \forall i \in [1, N] X_i == 0 1'. OP X_i == 0 <=>
\exists j \in [1, N] X_j == 0
2. f(x) == 0 <=> x == 0
>From 1 and 2 (or 1' and 2), we can infer that
OP f(X_i) == 0 <=> OP X_i == 0.
For some of the OP's and f's, we need to have domain constraints on X to
ensure properties 1 (or 1') and 2.
In this change we support the following operations f:
1. f(x) = shl nuw x, y for arbitrary y
2. f(x) = mul nuw x, c for defined c != 0
3. f(x) = zext x
4. f(x) = sext x
5. f(x) = neg x
And the following reductions OP:
a. OR X_i - has property 1 for every X
b. UMAX X_i - has property 1 for every X
c. UMIN X_i - has property 1' for every X
d. SMAX X_i - has property 1 for X >= 0
e. SMIN X_i - has property 1' for X >= 0
f. ADD X_i - has property 1 for X >= 0 && ADD X_i doesn't sign wrap

Gathered loads forming DAG instead of trees in SLP vectorizer. When

The patch adds this analysis and allows cutting off the expensive

also add to the difficulty of dependency analysis. Skip such types

[InstCombine] Don't convert a compare+select into a minnum/maxnum intrinsic that can't be lowered back to a compare+select (#177821)
This is a step on the yak-shaving expedition to properly implement the
new `minnum`/`maxnum` signed-zero semantics.
`InstCombineSelect` will convert a `fcmp`+`select` sequence to a
`minnum`/`maxnum` intrinsic. It doesn't require the `fcmp` to have any
particular fast-math flags, just that the `select` has `nnan` and `nsz`
(or is being used in a context where the result doesn't care about
signed zero).
It's not correct to propagate the `nnan` flag from the `fcmp`
instruction for poison-propagation reasons. Patches like
https://github.com/llvm/llvm-project/pull/117977 and
https://github.com/llvm/llvm-project/pull/141010 have *generously* made
it so that if `fcmp` doesn't have fast-math flags, we can still perform
the transformation by simply dropping the flags on the generated
intrinsic.
Unfortunately, converting an `fcmp`+`select` with fast-math flags, to a
`minnum`/`maxnum` without fast-math flags, is actually a
*pessimization*. Common ISAs like x86 and WebAssembly do not provide
single floating-point minimum/maximum instructions that handle NaN in
the same way as `minnum`/`maxnum`. They have to fall back to a routine
or a libcall, which causes its own problems
(https://github.com/llvm/llvm-project/issues/54554).
[Here's an example](https://llvm.godbolt.org/z/avYxa7ccK). Using just
`llc`, the function compiles to a single `maxss`. But with `clang -O3`,
which enables InstCombine optimizations, we end up with a much larger
(and completely unnecessary) routine for handling NaNs.
We should only perform this transformation if it's safe to add `nnan`
and `nsz` to the `minnum`/`maxnum` call, since those are the flags
necessary for lowering it *back* into an `fcmp`+`select` (or equivalent
code).
There's currently one case where we might end up without `nsz` on the
intrinsic call: if the output has one use, and that use doesn't care
about signed zero. To account for that, we should also unconditionally
set `nsz` on the generated intrinsic call.
With this in place, it should be safe to eventually revert
https://reviews.llvm.org/D122610 and further consolidate
`minnum`/`maxnum` handling.

TargetLowering: Allow FMINNUM/FMAXNUM to lower to FMINIMUM/FMAXIMUM even without `nsz` (#177828)
This restriction was originally added in
https://reviews.llvm.org/D143256, with the given justification:
> Currently, in TargetLowering, if the target does not support fminnum,
we lower to fminimum if neither operand could be a NaN. But this isn't
quite correct because fminnum and fminimum treat +/-0 differently; so,
we need to prove that one of the operands isn't a zero.
As far as I can tell, this was never correct. Before
https://github.com/llvm/llvm-project/pull/172012, `minnum` and `maxnum`
were nondeterministic with regards to signed zero, so it's always been
perfectly legal to lower them to operations that order signed zeroes.

[OpenCL] Add clang internal extension __cl_clang_function_scope_local_variables (#176726)
OpenCL spec restricts that variable in local address space can only be
declared at kernel function scope.
Add a Clang internal extension __cl_clang_function_scope_local_variables
to lift the restriction.
To expose static local allocations at kernel scope, targets can either
force-inline non-kernel functions that declare local memory or pass a
kernel-allocated local buffer to those functions via an implicit argument.
Motivation: support local memory allocation in libclc's implementation
of work-group collective built-ins, see example at:
https://github.com/intel/llvm/blob/41455e305117/libclc/libspirv/lib/amdgcn-amdhsa/group/collectives_helpers.ll
https://github.com/intel/llvm/blob/41455e305117/libclc/libspirv/lib/amdgcn-amdhsa/group/collectives.cl#L182
Right now this is a Clang-only OpenCL extension intended for compiling
OpenCL libraries with Clang. It could be proposed as a standard OpenCL
extension in the future.

[clang][bytecode] Fix crash on discarded complex comparison (#177731)
Fixes llvm#176902: [clang][bytecode] crashes on ill-formed
_Static_assert comparing complex value
This patch resolves a crash in Clang's constant evaluation when handling
complex number comparisons in discarded expressions, such as those
involving short-circuiting logical operators. The crash occurred due to
unnecessary evaluation of the comparison in the experimental constant
interpreter.
The issue was originally observed and minimized in the following
example:
```cpp
#define EVAL(a, b) _Static_assert(a == b, "")
void foo() {
EVAL(; + 0, 1i);
}
```
This patch ensures that such comparisons are handled correctly without
triggering assertions when the result is discarded.
Tests
A regression test has been added to verify that complex comparisons in
discarded expressions no longer cause crashes during constant
evaluation.
Local verification:
llvm-project-main/clang/lib/AST/ByteCode/constant-eval-complex-discard.c
passes.
Full ninja check-clang may fail locally due to a known GCC ICE when
building Clang unittests; this is unrelated to the change itself.

[AMDGPU][SILoadStoreOptimizer] Fix lds address operand offset (#176816)
The offset operand in GLOBAL_LOAD_ASYNC_TO_LDS_B128, for instance, is
added to both the lds and global address, but SILoadStoreOptimizer is
currently unaware of that. This PR inserts an add to counteract the
offset meant for the global address. This one add is better than not
doing the optimization at all, and having to insert 2 adds for each
global address calculation (with no offset).

This PR also promotes the global address to an offset when the offset is
calculated with V_ADD_U64 on applicable gfx versions, (and inversely
adds the LDS offset), whereas previously the optimization opportunity
was missed entirely.

[IRMover] Use signature for exact definition (#177381)
It is possible for optimizations to modify attributes on exact
definitions. In particular, DeadArgumentElimination may find that a
certain argument is dead, and replace arguments in calls with `poison`.
This requires dropping the `noundef` attribute on the argument.
When ThinLTO import is performed, the destination module already has a
declaration for the function, and the definition is not imported (e.g.
because it is noinline), we currently simply retain the original
declaration. This is incorrect if call with poison arguments were
imported, as the calls become immediate UB.
There was a previous attempt to address this in
https://reviews.llvm.org/D139209. What that patch did was to fix up the
attributes of the declaration after the fact, dropping UB implying
attributes that are not present on the definition. It was reverted
because it made an incorrect assumption that the signature between the
declaration and definition must match.
In this PR, I propose to fix the issue in a different way: If the source
module holds an exact definition (which are the ones that can be, in
limited ways, modified by optimizations), then even if we don't import
the definition, we should still import a declaration based on it. This
ensures that we respect any dropped attributes. (It's probably also
useful for optimization purposes, because we also see more inferred
attributes.)

[ARM] Count register copies when estimating function size (#175763)
`EstimateFunctionSizeInBytes`, in `ARMFrameLowering.cpp`, provides an
early estimate of the compiled size of a function, in a context that
wants to overestimate rather than underestimate.
In some cases it was underestimating severely, by over 20%. The
discrepancy was entirely accounted for by the fact that `COPY`
operations were not being counted at all, even though each one (or at
least each one that survives any post-regalloc optimizations) takes 2
bytes in Thumb or 4 in Arm. This could lead to a compile failure, if the
underestimated function size led frame lowering to not stack LR, but
later, `ARMConstantIslandsPass` needed to insert an intra-function
branch long enough to require a `bl` instruction, needing LR to have
been stacked.
The result of `EstimateFunctionSizeInBytes` was not directly available
for testing, so I added an `LLVM_DEBUG` at the end of the function. That
way, the test file doesn't need to try to make a >2048 byte function
estimated at <2048 bytes; it just needs to exhibit a function with a
single `COPY` and make sure it's counted.
At the moment, `EstimateFunctionSizeInBytes` is only used at all in
Thumb-1 compilations, to decide whether the function is large enough to
justify stacking LR as a precaution. However, the subroutine
`ARMBaseInstrInfo::getInstSizeInBytes` which counts each individual
`MachineInstr` is called from other contexts too, so I've made it return
a sensible answer for `COPY` nodes in both of Arm and Thumb.

[lldb] Fix error when running "memory region --all" repeatedly (#177176)
Due to some faulty logic, if you ran "memory region --all" twice, the
second time lldb would try to repeat the command. There's nothing to
repeat, so it failed with an error. It should treat each "--all" use as
starting from scratch.
The logic here was written in a confusing way, so I've refactored it to
first look at how many arguments there are (aka how many address
expressions there are) and then validate based on that.
For reasons unknown, I could not reproduce this issue using the API test
TestMemoryRegion.py. So I have added a shell test that I confirmed does
fail without this fix.

[LifetimeSafety] Add suggestion and inference for implicit this (#176703)
This PR implements support for automatically suggesting and inferring
`[[clang::lifetimebound]]` annotations for the implicit `this`.
The analysis now models the implicit this object as an implicit
parameter that carries a "placeholder loan" from the caller's scope. By
tracking this loan through the method body, the analysis can identify if
this reaches an escape point, such as a return statement.
Key Changes:
- Updated `PlaceholderLoan` to hold a union of `ParmVarDecl*` and
`CXXMethodDecl*`
- Extended `OriginManager` to handle `CXXThisExpr` and create a
dedicated origin list for the implicit this parameter
- Modified `FactsGenerator::issuePlaceholderLoans` to create a
placeholder loan for this at the entry of non-static member functions
- Updated `implicitObjectParamIsLifetimeBound` in
`LifetimeAnnotations.cpp` to check for the attribute on the method
declaration itself
- Added logic to skip implicit methods and standard assignment operators
to avoid redundant warnings on boilerplate code
Example:
```cpp
struct ReturnsSelf {
const ReturnsSelf& get() const {
return *this;
}
};
void test_get_on_temporary() {
const ReturnsSelf& s_ref = ReturnsSelf().get();
(void)s_ref;
}
```
Warning:
```

[lldb-dap] Fix the completion provided to the DAP client. (#177151)
Previously, completion behavior was inconsistent,
sometimes including the partial token or removing existing user text.
Since LLDB completions includes the partial token by default, we now
strip it before sending to the client.
The completion heuristic:
1. Strip the commandEscapePrefix
2. Request completions from the debugger
3. Get the line at cursor position
4. Calculate the length of any partial token
5. Offset each completion by the partial token length
In all cases, the completion starts from the cursor position. then
offsets by `Length` to the left and inserts the completion.
Examples (single quotes show whitespace and are not part of the input):
```md
| Input | Partial Token | Length | Completion |
|------------|---------------|--------|---------------|
| m | m | 1 | memory |
| `m | m | 1 | memory |
| myfoo. | myfoo. | 6 | myfoo.method( |
| myfoo.fi | myfoo.fi | 7 | myfoo.field |
| myfoo. b | b | 1 | myfoo. bar |
| 'memory ' | | 0 | memory read |
| memory | memory | 6 | memory |
| settings s | s | 1 | settings show |
```

[libclc] Rework libclc naming convention to use the triple (#177465)
Summary:
Right now all these libraries are installed in the `libclc/` directory
in the compiler's resource directory. We should instead follow the
per-target approach and install it according to the triple. The
sub-architectures will be put in a subdirectory as well.
I will do refactorings on this later to remove all the redundant targets
and pull this into common handling.
Also we should accept `--libclc-lib` without an argument to just find it
by default. I don't know what the plan here is since AMDGCN is the only
triple that uses this flag.

Normally I would push back on implementations that take O(BitWidth)

O(BitWidth) steps, this KnownBits function is no worse in that regard.
Also add the same early-out optimization to both the APInt function and
the KnownBits function.

[flang][Lower] Fix UB in location handling (#177944)
Previously `prov` received the address of a variable allocated in stack
memory (the contents of `include`). `prov` would then access that memory
outside of the lifetime of that stack allocation: leading to UB.
This only manifested on thinLTO builds. No added test because
flang/test/Lower/location.f90 covers it (when thinLTO is enabled) and
there are bots guarding the thin-lto configuration.

[SDAG] Remove non-canonical fabs libcall handling (#177967)
This is a followup to https://github.com/llvm/llvm-project/pull/171288,
which removed lowering of libcalls to SDAG nodes for most libcalls that
get unconditionally canonicalized to intrinsics. This handles the
remaining fabs case, which I originally skipped due to larger test
impact.

AMDGPU: Move softPromoteHalfType override to R600 only (#177419)

We could do a better job with source modifier management around
fp16_to_fp/fp_to_fp16.

R600: Remove softPromoteHalfType (#177420)
Also includes a kind of hacky, minimal change to avoid assertions
when softPromoteHalfType is removed to fix kernel arguments
lowered as f16. Half support was never really implemented
for r600, and there just happened to be a few incidental tests
which included a half argument (which were also not even meaningful,
since the function body just folded to nothing due to no callable
function support).

[AMDGPU] Simplify legalization of PHI operands (#177352)
In practice when legalizeOperands is called on a PHI node, the result is
never an SGPR class and the operands are never subregs. Simplify the
code accordingly by using the result regclass for all the inputs. This
includes using an AV class where previously we picked either an AGPR or
VGPR class.

[lldb] Improve error and docs for repeating "memory region" (#177559)
"memory region" can be given an address once and then when repeated,
it will try to find a region just beyond the last one it printed.
This continues until the end of the address space.
Then it gives you an error showing the usage, which is odd because
you just saw a bunch of "memory region" with no options work.
So I've improved the error a bit to imply its to do with the repetition.
Then described the repeating behaviour in the help text.

[clang][bytecode] Avoid crash in constexpr wcslen on invalid argument… (#177891)
### What the problem ?
Fix a clang bytecode constant interpreter crash when evaluating
wcslen("x") in a constant-expression path.
Previously we asserted on wchar element size mismatch and crashed in
assertion builds.
### Why it happened
The expression is already ill-typed (char[2] → const wchar_t*), clang
correctly emits a diagnostic, but later ICE checking tries to fold the
expression and reaches the builtin handler. That path must not crash.
### whats the Fix
Replace the assert(ElemSize == wchar_t size) with a graceful failure
(return false / emit appropriate diagnostic) when element sizes don’t
match, so evaluation stops safely.
### how to Test it
Add a regression test that triggers ICE checking with
-fexperimental-new-constant-interpreter and ensures clang does not crash
(verifies it reports the type error / static_assert failure instead).
Fixes #177844.

[AMDGPU] Improve crash message when S_WAITCNT_DEPCTR is missing its operand (#177065)
The code in the test is causing a crash in `SIInstrInfo.cpp`
`fixImplicitOperands()` in `MI.implicit_operands()`:
```
for (auto &Op : MI.implicit_operands()) {
```
MachineInstr.h:
```
mop_range implicit_operands() {
=> return operands_impl().drop_front(getNumExplicitOperands());
}
```
We are trying to drop 1 operand from the operands of MI which are 0.
By early returning we are no longer crashing at that point and we are
getting a more meaningful error message:
```
*** Bad machine code: Too few operands ***
- function: missing_operand_crash
- basic block: %bb.0 (0x5a9d30ced988)
- instruction: S_WAITCNT_DEPCTR
1 operands expected, but 0 given.
```
The code is still crashing at a different location, but at least we are
getting an error message.

RISC-V to fail with `llvm_unreachable` panic.
Functionally, this is a small fix that also ports tests for the
aforementioned folds to RISCV.

-----------
[DTLTO] Make temporary file handling consistent (#176807)
DTLTO emits temporary files to allow distribution of archive member
inputs.
It also emits temporary files from the ThinLTO backend, such as the
index files needed for each distributed ThinLTO backend compilation.
This change brings archive member temporary files into line with those
produced by the ThinLTO backend. They are now emitted in the same
location, warnings are emitted if they cannot be deleted, and they are
cleaned up on abnormal exit (e.g. Ctrl-C). All temporary files are
preserved when --save-temps is specified.
The existing signal-handling test has been extended to cover the full
set of DTLTO temporary files, and a new test has been added to exercise
temporary file handling in normal operation. Additionally, a minimal
test has been added to show the COFF behaviour.

[RISC-V] Fix outliner candidate analysis (#177126)
When analyzing outliner candidates, there is no check that the tail-call
expansion register is live across the candidate call site. That can
result in a situation where the original function sets the volatile
register and uses it in the section that gets outlined. This of course
results in the use of the register receiving the incorrect value. Namely
the address of the outlined function since that is what the tail-call
sequence placed in the register.

[lldb][windows] do not attach to a PseudoConsole if it is not opened (#177934)
# Summary
This patch ensures lldb will not try to read from a PseudoConsole if it
has not been opened.
# Original issue
https://github.com/llvm/llvm-project/pull/168729 introduces support for
the Windows ConPTY in `lldb-dap`. This caused a regression in `lldb`
which was not caught by our tests:
https://github.com/llvm/llvm-project/issues/175652.
This patch fixes https://github.com/llvm/llvm-project/issues/175652.
`lldb_private::ProcessLauncherWindows::LaunchProcess` connects the
debuggee to a PseudoConsole only if:
```cpp
if (hPC != INVALID_HANDLE_VALUE && launch_info.GetNumFileActions() == 0 && launch_info.GetFlags().Test(lldb::eLaunchFlagLaunchInTTY))
```
lldb needs to check the same condition in
`lldb_private::PlatformWindows::DebugProcess` to ensure that it does not
read from a PseudoConsole which has not been opened.
# Side effect
This patch reverts what https://github.com/llvm/llvm-project/pull/168729
did by adding ConPTY support.
https://github.com/llvm/llvm-project/pull/175812 is the proper fix,
however it's causing tests failures which we can't reliably reproduce at
desk. Given https://github.com/llvm/llvm-project/pull/168729 breaks
`22.x` lldb, it's better to revert the change ahead of the release of
`22.x` rather than pushing for the proper fix.

[clang-tidy] Speed up `readability-container-contains` (#175121)
This is currently one of our most expensive checks according to
`--enable-check-profile`. I measured using [the usual
setup](https://github.com/llvm/llvm-project/pull/174357#issue-3780188615):
```sh
hyperfine \
--shell=none \
--prepare='cmake --build build/release --target clang-tidy' \
'./build/release/bin/clang-tidy --checks=-*,readability-container-contains all_headers.cpp -header-filter=.* -system-headers -- -std=c++23 -fno-delayed-template-parsing'
```
First, the status quo:
```txt
Time (mean ± σ): 5.243 s ± 0.158 s [User: 4.964 s, System: 0.248 s]
Range (min … max): 5.133 s … 5.612 s 10 runs
```
This PR improves that in two independent commits. The first commit
changes the default traversal mode from `TK_AsIs` to
`TK_IgnoreUnlessSpelledInSource`. Result:
```txt
Time (mean ± σ): 4.554 s ± 0.100 s [User: 4.273 s, System: 0.248 s]
Range (min … max): 4.442 s … 4.785 s 10 runs
```
The second commit merges all 12 of the check's `BinaryOperation`
matchers into one, because I found that each additional registered
`BinaryOperation` matcher has pretty extreme overhead. Result:
```txt
Time (mean ± σ): 3.480 s ± 0.121 s [User: 3.264 s, System: 0.186 s]
Range (min … max): 3.400 s … 3.798 s 10 runs

This patch fixes the
`ProcessSaveCoreTestCase.test_save_core_to_nonwritable_dir` test on
Windows.
This test fails on Windows because `os.chmod` does not work on Windows.
It was used to make the directory unwritable.
[`icacls`](https://learn.microsoft.com/en-us/windows-server/administration/windows-commands/icacls)
can be used instead to block the directory.
This is a followup to https://github.com/llvm/llvm-project/pull/177496.

[SystemZ] Support fp16 vector ABI and basic codegen. (#171066)
- Make v8f16 a legal type so that arguments can be passed in vector
registers. Handle fp16 vectors so that they have the same ABI as other
fp vectors.
- Set the preferred vector action for fp16 vectors to "split". This will
scalarize all operations, which is not always necessary (like with
memory operations), but it avoids the superfluous operations that result
after first widening and then scalarizing a narrow vector (like v4f16).

[mlir][gpu] Add address space modifier to gpu.barrier (#177425)
This is a takeover of PR ##110527
This commit adds an optional list of memory fences to gpu.barrier,
allowing users to specify which memory scopes they wish to fence
explicitly, while leaving the default semantics (which are equivalent to
calling for a global and local fence by analogy to CUDA's __syncthreads)
unchanged. The new expanded semantics are implemented for SPIR-V and for
the AMDGPU backend.
See also
https://discourse.llvm.org/t/rfc-add-memory-scope-to-gpu-barrier/81021/2?u=fmarno,
where the default behavior of a gpu.barrier was hashed out (though note
that the examples based on VMCNT are outdated for AMDGPU in that memory
fences can now be annotated with the correct set of address spaces).
This commit also deprecates amdgpu.lds_barrier for usecases that don't
involve targeting a gfx908.
Assisted-by: Cursor/Claude code (tests and extending amdgpu.lds_barrier
pattern while copying it over)

[OpenMP] Cleanup synchronization primitives (#177710)
Summary:
These shouldn't be so different after we moved away from variants. It's
much simpler to define this in-line with a single preprocessor
definition. This should be equivalent less a few unnecessary function
definitions with the advantage that SPIR-V now has less work to do.

[libc++][NFC] Move attribute macros out of __config into a detail header (#176903)
This patch moves all macros which expand to attributes into a detail
header, including the relatively complex visibility and ABI-hiding
attributes. This also adds sections for attributes that are important to
not be ignored. At the bottom there is a catch-all section for
attributes which can safely be ignored and are only important for the
quality of implementation.

This simplifies the code a bit.

As the OpenACC dialect is decomposed and further lowered, we need a

included from OpenACCOps.td, to hold such intermediate operations.
The `acc.kernel_environment` and `acc.firstprivate_map` operations are
moved to this new file.

[SystemZ][asan] Improve error handling for pragma export as a statement (#177979)
The changes in https://github.com/llvm/llvm-project/pull/141671 had a
failure in some asan bots. The code for parsing pragma export is the
same as for the MS pragmas. I did noticed that the MS pragma handling
code says the tokens are reinjected when calling EnterTokenStream(). Do
the same for pragma export.
The tokens on the MS pragma and pragma export are handled by:
1. PragmaMSPragma::HandlePragma
- collect the tokens into an array
- an annotated token is created with the pragma token & array of tokens
- calls EnterToken() adds the annotated token
2. Parser::HandlePragmaMSPragma()
- takes the array of tokens off the annotated token can adds them to the
stream using EnterTokenStream()
- this call says the tokens are reinjected.

[RISC-V][Mach-O] Add assembler support for Mach-O relocations. (#177446)
This patch adds comprehensive assembler (MC layer) support for the
Mach-O object file format on RISC-V targets, enabling assembly and
disassembly of RISC-V code targeting Apple platforms.
Key changes:
- Define RISC-V-specific Mach-O relocation types in BinaryFormat/MachO.h
- Implement RISCVMachObjectWriter with full relocation handling for:
- PCREL_HI/LO pairs for PC-relative addressing
- GOT relocations for external symbols
- Branch relocations (CALL, unconditional/conditional branches)
- Data section relocations
Test files include llvm-otool dumps to verify the generated relocations.
This code is based on code originally written by Tim Northover.

[lldb] Fix Python stderr redirection in test (#177970)
Python's internal stderr may differ from sys.stderr.
When Python writes errors, it uses its internal stderr rather than the
overwritten sys.stderr.
This may not be the same file/handle
Fix the test to explicitly write to the specified stderr.

[NFCI][MemoryTaggingSupport] Replace getAllocatedType with getAllocationSize (#177436)
Replace the `isSized()` and `isScalableTy()` type predicate checks with
a more direct `getAllocationSize()` query. The `isSized` check seems
unnecessary since the verifier already rejects unsized alloca.
For context, I'm working on deleting (or at least minimizing uses of)
the getAllocatedType function, since many optimizations need to destroy
that info and just produce byte sized allocas. It is for the same
reason that opaque pointers were introduced–memory doesn't inherently
have a provenience type, only uses (load and stores) do.

[CIR] Add custom constructor declaration to CIR lowering TableGen (#176664)
While working on the lowering of `BlockAddressOp`, I ran into a
limitation of the current `CIRLoweringEmitter` infrastructure: some CIR
ops require shared mutable state across multiple lowering patterns, but
the generated patterns always use a fixed default constructor and cannot
accept additional context.
**Examples:**
* `BlockAddressOp` needs to coordinate with the lowering of its
referenced `LabelOp`, requiring shared bookkeeping (e.g.
`LLVMBlockAddressInfo`) to track lowered labels and resolve unresolved
block addresses once the corresponding `BlockTagOp` is available.
* This is not unique to block addresses: for example,
`CIRToLLVMAllocaOpLowering` will also need access to shared state such
as `stringGlobalsMap`, `argStringGlobalsMap`, and `argsVarMap`.
**Possible solution:**
* **Disable generated lowering**: mark the op with `hasLLVMLowering =
false` and manually define and register the lowering patterns. This
works, but feels misleading since the operation does have an LLVM
lowering it just cannot be generated automatically. This ambiguity also
suggests that `hasLLVMLowering` might be better named `genLLVMLowering`.
* **Custom constructors (this PR)**: extend the TableGen emitter to
allow defining a single custom constructor for the generated LLVM
lowering pattern, similar to MLIR’s `OpBuilder`. When a custom
constructor is provided, the default one is not generated and the
pattern must be manually registered in the RewritePatternSet.

[InstCombine] Replace getAllocatedType() with getAllocationSize() (#177435)
Replace uses of getAllocatedType() with the more semantic
getAllocationSize() method in the alloca dereferenceability check
and zero-size alloca merging logic.
This simplifies the code by:
- Eliminating manual isArrayAllocation() checks (handled by
getAllocationSize)
- Eliminating superfluous isSized() checks (the verifier rejects them
already)
- Using TypeSize::isScalable() for scalable vector handling (before
casting to uint64_t)
- Using TypeSize::isZero() for zero-size checks

[FunctionSpecialization] Remove getAllocatedType() type check (#177439)
Change getConstantStackValue() to check the type of the promoted
constant rather than the alloca's declared type. This is more correct
semantically since we're interested in the actual stored value's type,
not what the alloca was declared as.
The change also handles type punning cases more conservatively - if an
alloca is declared as i64 but stores a float, the old code would pass
the integer type check but potentially return a non-integer constant.
The new code correctly rejects such cases.
Also remove a bit of dead code, since the argument is a pointer type, it
cannot also have been a constant integer (and this code would be wrong
if it was reachable). Originally introduced as dead code in

LiveValue->getType(), so we can use Def->getType() (which equals the
alloca's type) instead of querying getAllocatedType().
Changes:
- Load instructions now use Def->getType() directly
- The ToClobber vector now stores (Type*, AllocaInst*) pairs to track
the original value's type for creating null constants

Replace repeated calls with getAllocationSize() and cached NewAllocaTy.
In AllocaSliceRewriter, the allocated type is already stored in the
NewAllocaTy member variable and now passed directly there. This change
replaces the remaining direct calls to `NewAI.getAllocatedType()` with
the cached NewAllocaTy to simplify and DRY the code.

handleErrors supports several different handler signatures, including
handlers that take a unique_ptr<T> (where T is a descendant of
ErrorInfoBase) and return an Error: (std::unique_ptr<T>) -> Error. In
this case the handler should be able to create an Error value to wrap
the original ErrorInfoBase object without.
This functionality was not previously tested, and will be used in
upcoming commits. This commit adds the missing test coverage.

[clang][bytecode] Fix crash in void functions returning non-void expr… (#176550)
The bytecode compiler was incorrectly emitting an
RVOPtr
opcode for void functions if the return expression had a non-void type
(e.g. from a conditional operator). This triggered an assertion in the
interpreter because void functions lack RVO metadata.
This patch updates
visitReturnStmt
to check the function’s return type and use
discard()
for the expression in void contexts, preventing erroneous RVO pathing.
Fixes #176536

This commit introduces a C interface for the ORC runtime's Error
handling system, enabling C clients and language bindings to work with
ORC errors.
The ORC_RT_C_ABI macro applies __attribute__((visibility("default")))
(on platforms that support it), ensuring C API symbols are exported when
building the ORC runtime as a shared library. In the future I expect
that this will be extended to support other platforms (e.g. dllexport on
Windows).

And, similar optimization like #77284 is added too.
After this patch, the highly predictable branch will be converted
back to branches instead using selects.
This pass is disabled by default now, we can enable it by default
after more detailed investigation.

Changes:
- Add hasCanonicalizeMethod to BrOp in CIROps.td
- Implement BrOp::canonicalize in CIRDialect.cpp
- Auto-collect canonicalization patterns from all registered ops
in CIRCanonicalizePass (matching MLIR's Canonicalizer approach)
- Remove the standalone RemoveRedundantBranches pattern class

[mlir][emitc] Fix recurring operands in expression (#175535)
The pretty-printing for `emitc.expression` breaks for expressions taking
the same value as operand multiple times.
Passing the same value as operand more than once is redundant, and is
therefore not the canonical form of `emitc.expression`. However, since
transformations affecting `emitc.expression` operands may cause this to
happen, `emitc.expression` must retain its support for recurring
operands.
This PR fixes this issue by shadowing the region arguments only when the
operands are unique, printing and parsing an explicit basic block
otherwise. In addition, a canonicalization pattern removing recurring
operands is added.
Fixes https://github.com/llvm/llvm-project/issues/172952.

When SVE is available use the `-sve` variant of memcpy from AOR for
`__arm_sc_memcpy`. From:
https://github.com/ARM-software/optimized-routines/blob/71e36403858ab3ff743fcde336fb31890e57af7e/string/aarch64/memcpy-sve.S
This implementation uses FPR/ZPR load/store instructions to do the copy,
so should not cause memory hazards if called in streaming mode (with the
memory later being accessed in the streaming mode with SVE/SME
instructions).
The implementation has been slightly modified from AOR to use local
labels (matching other compiler-rt functions) but still passes the
memcpy and memmove tests from AOR.

Allow the no_stack_protector attribute on local variables (#173311)
This attribute is currently only permitted on functions, but sometimes
it can be useful to opt out a specific local variable. That way the
function can still get a stack protector if other locals require it, but
locals which are opted out won't have the overhead of a stack protector
if not needed.
This is paired with an LLVM change which has already landed, which uses
the new metadata to opt specific alloca instructions out of requiring a
stack protector.

[lldb][UserExpression] Delay deletion of failed user expression (#177921)
Instead of creating a new `UserExpressionSP` for the fix-it expression,
just re-use the existing `user_expression_sp`. We used to always reset
it when an expression failed, even if no fix-it was available. An
upcoming patch will need the `user_expression_sp` to be alive at the
point where we set up the diagnostic errors. So this patch removes the
unconditional `reset()` on `!parse_success` in favour of resetting it to
the new fixed expression, if one is available.

[libc++] Refactor how we do amortized growth (#171117)
When doing amortized growth we currently have separate functions for
calculating the new capacity and allocating. However, we set the size to
the calculated capacity that way instead of the actually required size.
This makes the interface quite confusing, since the size has to be set
manually. Instead, this patch refactors the function to get the
amortized growth capacity to instead allocate and set the size
correctly.

[flang][acc] remap variable in device_ptr clauses (#177018)
I previously disabled the variable remapping to data operand results in
the IR for the deviceptr clause because it was not clear how fir.box
would be dealt with and the remapping increased the usage of fir.box.
Since then, it was clarified that lowering could use fir.box and that it
would be up to the runtime to deal with the fact that the fir.box is
implemented by a descriptor allocated on the host and containing the
base address of an entity on the device.
Remove the workaround.

[flang] emit declare for function result before call (#177615)
This change moves the declare of result storage alloca before the call
so that alias analysis can revert to linking fir.declare to the fisrt
dominating dummy_scope instead of the dominating one.
This is only relevant when MLIR inlining is enabled and is the first
step to fix issues recent TBAA changes that placed target data in its
own tree exposed an issue with the result storage of a TARGET result.
After inlining, the usages of the result storage inside the callee and
after the call ended-up being placed in different nodes (target and non
target) of the same TBAA tree (for the dominating function).
The fact that both nodes are placed in the same tree stems from
https://github.com/llvm/llvm-project/pull/146006 that fixed another TBAA
issue related to MLIR inlining and function result where the function
result was placed into the wrong TBAA tree, which with nested inlining
could end-up being the tree of a callee where the result storage was a
dummy, causing the TBAA to wrongfully tell that any access to the result
storage inside the nested callee did not alias with any access after the
call.
By moving the declare before the call that will be inlined, this patch
will allow reverting #146006 and fixing both issues: the TBAA emit for
usages of the result storage after the call will always be placed in a
different TBAA tree than any usages of the result storage inside the
callee.

AbstractConverter.h is pulling a lot of headers, including some from

need/usage of Evaluate data structures.
I opened https://github.com/llvm/llvm-project/issues/178142 to fully

patch should at least prevent the consumers of IntrinsicCall.h to
bring-in these extra libraries.

[mlir][dataflow] Drop the firstIndex argument of visitNonControlFlowArguments (#175210)
This PR improves the signature of `visitNonControlFlowArguments`:
- The function now takes non-successor-inputs ("non-control-flow
arguments") instead of successor inputs. This is more consistent with
the naming of the function.
- `firstIndex` is no longer needed and dropped. (It was needed only to
identify the non-successor-inputs among the block arguments / op
results.)
Background: Successor inputs are forwarded values (e.g., iter_args / op
results of an `scf.for`) and non-successor-inputs are all other block
arguments / op results (e.g., the loop induction variable of an
`scf.for`.)
Note for LLVM integration: `visitNonControlFlowArguments` now receives
the non-successor-input directly. You no longer have to find those among
the list of all block arguments / op results based on `firstIndex`.

[MemRef] Propagate strided layout through view-like ops in multiBuffer (#176941)
The memref::multiBuffer transformation replaces an allocation with a
multi-buffered allocation and creates a strided memref.subview at each
loop iteration. When the original allocation is used through view-like
ops, the existing code only handles SubViewOp, leaving other view-like
ops with incorrect types.
This patch extends replaceUsesAndPropagateType to handle ExpandShapeOp,
CollapseShapeOp, and CastOp using TypeSwitch. For each view-like op, we
compute the correct result type (or assert on failure) and create a new
operation, then recursively propagate the updated type through chains.
New FileCheck tests cover expand_shape, collapse_shape, cast, and a
chained expand_shape->cast case.
A single ViewLikeOpInterface hook is not practical here: view-like ops
have distinct type inference and validity rules (e.g., subview uses
offset/size/stride inference, expand/collapse use reassociation, cast
requires compatibility checks). Ops like memref.view or
memref.reinterpret_cast need additional layout/size validation beyond
what multi-buffering currently tracks, so this patch handles the common
safe cases directly.

[mlir][spirv] Enforce `SPIRV_Vector` to have rank of one (#178185)
Currently only vector length is enforced however this allows vectors of
rank >1 to pass the verification as long as the length agrees. This
change restricts `SPIRV_Vector`s to be of rank 1 as required by the
SPIR-V spec.
This also fixes a bug where `SPIRV_Composite` allowed high ranked
vectors but `spirv::CompositeType` did not leading to cast assertions
where the composite type was assumed.
Finally, this change adds two new common constraints that can enforce
all three: rank, length and type.

Address sanitizer recently got a new macro __SANITIZER_DISABLE_CONTAINER_OVERFLOW__

standard library or user libraries that might provide such checks). This patch makes
libc++ honor that macro and, in addition, cleans up how these checks are enabled for
string (which is special) by introducing a macro just for string.

[TTI] Add VectorInstrContext for context-aware insert/extract costs. (#175982)
This commit introduces the VectorInstrContext (VIC) infrastructure to
improve cost estimates for insert/extracts based on the context
instruction in which the insert/extract is used.
This is similar to CastContextHint, and allows providing context on how
the insert/extract is going to be used before creating IR. This is
useful in the LoopVectorizer, where costs need to estimated before
creating IR.
The new hint currently only replaces an existing check in AArch64,
but new uses will be introduced in follow-ups, including
https://github.com/llvm/llvm-project/pull/177201.

[regalloc][basic] Fix non-deterministic codegen in basic register allocator (#177998)
The basic register allocator's priority queue exhibited
non-deterministic behavior when multiple LiveIntervals had identical
spill weights. This caused different register allocation decisions
between ASAN and non-ASAN builds, leading to spurious test failures on
some internal tests.
Root Cause:
The CompSpillWeight comparator only compared spill weights:
```
return A->weight() < B->weight();
```
When two LiveIntervals had equal weights, the comparator returned false
for both comp(A,B) and comp(B,A), making them equivalent in the heap
ordering. The C++ standard does not specify the relative order of
equivalent elements in a heap. In practice, the heap's internal
structure for equivalent elements depends on implementation details and
memory layout. ASAN changes memory layout, leading to different valid
heap configurations and thus different dequeue order.
Fix:
Add an explicit stable tie-breaker using virtual register numbers:
```
return std::tuple(A->weight(), A->reg()) <
std::tuple(B->weight(), B->reg());
```
Register numbers are stable integers independent of memory layout,
ensuring deterministic behavior across all build configurations. When
spill weights are equal, higher-numbered virtual registers are allocated
first, which is equally valid and deterministic.
Test Updates:
Updated test expectations in
CodeGen/AMDGPU/register-killed-error-after-alloc-failure0.mir to reflect
the new deterministic allocation order. When LiveIntervals have equal
spill weights, the allocator now consistently processes them in register
number order rather than in an implementation-defined order.

precisely that it does not trigger any destruction of an object.
This PR also introduces alpha.webkit.NoDeleteChecker which validates
soundness of the annotation by examining the function body. The checker
will warn if `[[clang::annotate_type("webkit.nodelete")]]` is specified
on a function with a body which does not pass the triviality test.

[MLIR][TOSA] Guard scatter lowering against unranked operand (#178188)
### What the problem
--tosa-to-scf crashes when lowering tosa.scatter if operands are
unranked, because the lowering assumes RankedTensorType and later builds
tensor.extract_slice, which asserts on unranked tensors.
### Why it Happened
The current pattern does not check operand ranks before lowering, even
though the implementation hardcodes 3D (N,W,C) semantics and cannot
handle unranked or differently-ranked tensors.
### Whats The Fix
Add rank/type guards in ScatterOpConverter and fail the rewrite unless
operands are ranked with expected ranks (values/input: rank-3, indices:
rank-2), allowing legalization to fail gracefully instead of crashing.

[ASan] Fix UnpoisonDefaultStack stack bottom estimation (#178137)
UnpoisonDefaultStack estimates the stack bottom as:
```
bottom = ((uptr)&local_stack - page_size) & ~(page_size - 1);
```
However, this can try to poision memory that doesn't have a shadow (i.e.
AddrIsInMem(x) is false) if the local_stack variable is within two pages
of the actual bottom of the space available for stack. This causes the
unpoison-alternate-stack.cpp test (which allocates a very small stack)
to fail.
This PR changes this computation to check AddrIsInMem before subtracting
the additional page.

This PR implements a generic backend-agnostic parallel `std::is_sorted`
based on `std::transform_reduce`.
While this approach is suboptimal comparing a direct backend-specific
implementation, since it doesn't support early termination and requires
a reduction operation, it does show speedup when the dataset is large
enough and the comparator is not absolutely trivial.

[CIR] Implement 'noreturn' attribute for functions/calls. (#177978)
This mirrors what LLVM does, and requires propagating into the LLVM
dialect: When the user specifies 'noreturn' we propagate this down
throughout the stack.
Note the similar 'willreturn' is too strong of a guarantee (in that they
are not opposites of each other, as there is a 'unknown' implied by all
others), so we cannot use that on non-noreturn functions.

[RISCV] Replace VPatBinaryV_VX_VROTATE with VPatBinaryV_VX. NFC (#178254)
VPatBinaryV_VX_VROTATE appeared to be almost exact copy and paste of
VPatBinaryV_VX except it used 'XLenVT' instead of 'vti.Scalar'.
'vti.Scalar' is 'XLenVT' for integer vectors so this wasn't a real
difference.
This change allows VV_VX or VV_VX_VI combination classes to be used,
further reducing the code.
No tablegen outputs change with this patch.

[InstCombine][profcheck] More fixes for missing branch data in InstCombineCompares.cpp (#178084)
Again, these fixes are trivial as we're creating new select instructions
with predicates from existing select instructions.
In this case, we create one select instruction from two existing select
instructions, but since both existing select instructions have the same
predicate, their profile data should be the same, so we can reuse the
profile data from either instruction. Therefore, we arbitrarily reuse
the profile data from the first select instruction.

[AArch64] Align nontemporal store/load little-endian checks (#177468)
This patch aims to align all nontemporal store/load handling to
systematically enforce a little-endian target. This has been the
effective support LLVM had for NT store/load lowering (there has been no
effective support for big-endian, even with the inconsistencies).
The change in `llvm/lib/Target/AArch64/AArch64InstrInfo.td` is
effectively a NFC, because the only lowering of LDNP, in
`llvm/lib/Target/AArch64/AArch64ISelLowering.cpp`, have already checked
for `isLittleEndian`. The change in
`llvm/lib/Target/AArch64/AArch64TargetTransformInfo.h` affects its
single caller
`llvm/lib/Transforms/Vectorize/LoopVectorizationLegality.cpp`. The
previous logic has been wrong, enabling vectorization of effectively
illegal nontemporal store/load instructions on big-endian.

Stacked on https://github.com/llvm/llvm-project/pull/177799.
We're already able to fuse `fceil`, `ffloor`, `ftrunc`, and `fround`
followed by a float-to-int conversion into a single "rounded conversion"
instruction. However, we were not doing this for `froundeven`, even
though there's a "convert to integer, rounding to even" instruction
(`FCVTNS`/`FCVTNU`).

[mlir] Update all-reduce (& vector tests) to use workgroup barriers (#178285)
This commit updates the lowering of all-reduce operations to annotate
the generated barriers with `memfence [#gpu.address_space<workgroup>]`
so that these barriers do not force unrelated global memory operations
to complete. It similarly sets up the warp synchronization function in
the vectory distribuhte tests, since they also only read/write shared
memory.
In additon, this commit adds convenience builders for gpu.barrier, which
will allow it to either fence on a given address space or on the address
space of a provided memref.

[lldb] Enable locate module callback for main executable in launch mode (#176266)
During target creation for launch mode, the locate module callback was
not invoked for the main executable because the Target doesn't exist yet
when ModuleList::GetSharedModule is called. This prevented custom module
location logic from being applied to the main executable.
This change adds a PlatformSP to ModuleSpec so that GetSharedModule can
call the locate module callback using the Platform directly, even when
Target is not available. The Platform is now set on the ModuleSpec in
TargetList::CreateTargetInternal before calling ResolveExecutable.

[AArch64] Add vector floating-point round+convert patterns (#177801)
Stacked on https://github.com/llvm/llvm-project/pull/177800.
We were previously able to fuse *scalar* floating-point round + convert
to integer sequences into a single "rounding conversion" instruction.
This PR extends that to vectors.

Reland "[OpenMP][Mappers] Fix ref-count tracking for maps inserted by mappers. (#177059)" (#177673)
This reverts commit 5a457837dd988aa01c65820848381a5b99a74c0a.
Includes the test fix from
https://github.com/llvm/llvm-project/pull/177659.
The test had to be updated to exclude a scenario that was failing
with/without the change (involving mapping a struct with a byref member
with a mapper).
-----
**Original PR's description:**
This is a fix for https://github.com/llvm/llvm-project/issues/61636.
Ravi had this implemented downstream before he retired. This PR is a
chery-pick of that.
The test is taken from @jdoerfert's WIP change in
https://github.com/jdoerfert/llvm-project/commit/527bf4b1293f452aac1f872c4f771c7950b911f9.
The change partially undoes the changes done in
0caf736d7e1d16d1059553fc28dbac31f0b9f788, so @alexey-bataev might need
to take a look.

[NVPTX][AtomicExpandPass] Complete support for AtomicRMW in NVPTX (#176015)
This PR adds full support for atomicrmw in NVPTX. This includes:
- Memory order and syncscope support (changes in AtomicExpandPass.cpp,
NVPTXIntrinsics.td)
- Script-generated tests for integer and atomic operations
(atomicrmw.py, atomicrmw-sm*.ll in tests/CodeGen/NVPTX). Existing
atomics tests which are subsumed by these have been removed
(atomics-sm*.ll, atomics.ll, atomicrmw-expand.ll).
- ~~Changes shouldExpandAtomicRMWInIR to take a constant argument: This
is to allow some other TargetLowering constant-argument functions to
call it. This change touches several backends. An alternative solution
exists, but to me, this seems the "right" way.~~ Has been split out into
https://github.com/llvm/llvm-project/pull/176073. Rebased.
- NOTE: The initial load issued for atomicrmw emulation loops (and
cmpxchg emulation loops) must be a strong load. Currently,
AtomicExpandPass issues a weak load. Fixing this breaks several
backends. I'm planning to follow up with a separate PR.

[Mem2Reg] Remove extraneous getAllocatedType() check (#177438)
Replace uses of getAllocatedType() in PromoteMemoryToRegister.cpp with
type tracking from actual loads and stores. This makes the promotion
logic more semantic - it now checks that all loads/stores use a
consistent type rather than requiring them to match the alloca's
declared type.
Changes:
- isAllocaPromotable() now tracks the first load/store type seen and
ensures all subsequent accesses use the same type
- AllocaInfo gains a ValueType field populated during AnalyzeAlloca()
- PromoteMem2Reg tracks AllocaValueTypes alongside other per-alloca info
- PHI nodes and UndefValues are created using the tracked type
This is semantically more permissive - an alloca declared as i64 but
only accessed as i32 is now promotable. This is correct because the
alloca is just a blob of memory; what matters for Mem2Reg is consistent
access patterns.
Test changes:
- asan-stack-safety.ll: Changed loads/stores to volatile to prevent
promotion while preserving ASAN stack safety analysis behavior
- SPIRV pointer tests (array-skips-gep.ll, load-struct.ll,
store-struct.ll, store-to-array-first-element.ll): Added escape calls to
prevent alloca promotion, as these tests verify SPIRV backend handling
of Function-storage-class pointers

allowing additional factoring with the rotl with immediate patterns.
This is NFC because these patterns shouldn't make it to isel if the

[libclc] Make output filename configurable; rename top-level targets (#178119)
This PR relates to c5cb48c39701.
Pass `OUTPUT_FILENAME` to `add_libclc_builtin_set` to allow downstream
output naming (e.g. libspirv in
https://github.com/intel/llvm/tree/sycl/libclc).
Rename top-level target to `libclc-${ARG_TRIPLE}` to avoid collision
with `library-${ARG_ARCH_SUFFIX}` in our downstream when libclc TRIPLE
matches libspirv ARCH_SUFFIX.

[clang][driver][darwin] Switch back to using CanonicalName to identify the SDK instead of SupportedTargets (#178115)
The SDK's SupportedTarget for its CanonicalName doesn't necessarily have
an LLVMTargetTripleSys/LLVMTargetTripleEnvironment that matches the
CanonicalName. e.g. sometimes new SDKs use arm64-apple-ios1.0 during
bringup, but their CanonicalName is set to the new platform. Go back to
using CanonicalName to identify the SDK as a Triple::OSType, and expose
the Triple::EnvironmentType used to build the SDKPlatformInfo when
SupportedTargets isn't present.

[JumpThreading] Avoid unnecessary map resizing in gatherIncomingValuesToPhi (#173596)
Previously, `gatherIncomingValuesToPhi` populated the `IncomingValues`
map with *all* non-undef incoming values from the PHI node. For PHI
nodes with a large number of incoming blocks, this caused the
`SmallDenseMap` to grow significantly, triggering expensive resizing and
rehashing operations, even when the caller
(`redirectValuesFromPredecessorsToPhi`) was only interested in a small
subset of predecessors.
This patch optimizes the logic to prevent this unnecessary map growth.
Instead of collecting all values, we now:
1. Initialize the `IncomingValues` map specifically for the blocks in
`BBPreds` (setting them to `nullptr` initially).
2. Iterate through the PHI node and update the map entries only if the
incoming block is already present in the map.
This ensures that the size of the map is bounded by the size of
`BBPreds`. Since `BBPreds` is typically small, this change keeps the map
within the `SmallDenseMap`'s inline storage in most cases, eliminating
heap allocations and resizing overhead for large PHI nodes.
The `selectIncomingValueForBlock` and `replaceUndefValuesInPhi` helpers
are also updated to handle map entries where the value is `nullptr`.

**LLVM changes:**
- Add r5900 CPU definition (with soft float support for now)
- Disable instructions not supported by r5900 (64-bit multiply/divide,
LL/SC atomics, COP3)
- Add r5900 specific short loop delay slot fix (hardware errata
workaround)
- Set ISA extension `AFL_EXT_5900` in ELF flags for proper ABI
identification
**Clang changes:**
- Add r5900 as a valid CPU target for `-mcpu=r5900`
- Add r5900 to CPU test coverage

This PR enables the option `-fpatchable-function-entry` for SystemZ. It
utilizes existing common code and just adds the emission of nops after
the function label in the backend.
SystemZ provides multiple nop options of varying length, making the
semantics of this option somewhat ambiguous. In order to align with what
`gcc` does with that same option, we#re choosing `nopr` as the
canoonical nop for this purpose.
For test, this adapts an existing test file from aarch64.

[lldb] Make "help format" test more strict (#178216)
Originally added in a81bd7f1014f316b42bf7274f76a340b833e663b /
https://reviews.llvm.org/D35525, this test either was not strict enough,
or lldb's behaviour has drifted since.
I think the intention was to check exactly when the output of "help
format" would wrap. Which should happen when we have printed up to the
terminal width, minus a few characters because we walk backwards to the
closest whitespace point to break at (so we don't split a word).
I've updated the test to check the exact outputs and cover printing one
line and two instances where we need to split different amounts onto a
second line.

[X86] X86FixupInstTunings - attempt to convert VPERMQri to VINSERTI128rri (#177327)
When the immediate is 0x44, VPERMQ/VPERMPD duplicates the lower 128-bit
lane to both lanes. This is equivalent to inserting the lower 128-bits
into the upper 128-bit position, which VINSERTI128/VINSERTF128 can
potentially do more efficiently on some targets.
This patch enables X86FixupInstTuning to convert:
VPERMQ ymm, ymm, 0x44 -> VINSERTI128 ymm, ymm, xmm, 1
VPERMPD ymm, ymm, 0x44 -> VINSERTF128 ymm, ymm, xmm, 1

[AMDGPU] Fix legacy index in fmed3 optimization (#177426)
The `matchFPMed3ToClamp` implementation incorrectly used the old
indexing for arguments from when it was wrapped in an intrinsic
instruction (i.e. the arguments would start at index 2). This missed
case was however in a conditional part of the optimization that would
only be hit if none of the other optimizations were hit. This commit
fixes this path and adds a test ensuring the path is tested in the
future.

There was no real benefit to disallowing this, and it sometimes caused

This effectively makes -check-prefixes the primary option and
-check-prefix just an alias of it. The documentation is upated
accordingly.

[AMDGPU] Fix buggy insertion of DEALLOC_VGPRS message (#178401)
We inserted the DEALLOC_VGPRS message if there were no pending scratch
stores the first time an S_ENDPGM instruction was visited. But because
this pass uses a worklist to revisit blocks until it reaches a fixed
point, it is possible that pending scratch stores are only discovered on
the second or later visit to a block. Fix this by storing a flag for
each S_ENDPGM instruction which can be updated by later visits.

[LifetimeSafety] Detect dangling fields (#177363)
Detect dangling field references when stack memory escapes to class
fields. This change extends lifetime safety analysis to detect a common
class of temporal memory safety bugs where local variables or parameters
are stored in class fields but outlive their scope.
- Added a new `FieldEscapeFact` class to represent when an origin
escapes via assignment to a field
- Refactored `OriginEscapesFact` into a base class with specialized
subclasses for different escape scenarios
- Added detection for stack memory escaping to fields in constructors
and member functions
- Implemented new diagnostic for dangling field references with
appropriate warning messages
Importantly,
- Added `AddParameterDtors` option to CFG to add parameter dtors and
lifetime ends behind an option. In principle, parameters ctors and dtors
do not belong in the function context but in the caller context. This
becomes incorrect to include in function's CFG when we have inlined CFGs
like some analyses in the analyzer (produces double dtors for
arguments). Therefore this provides a way to opt-in to know about
destructed params on function exits.

implements 5 attributes for CIR/Clang CIR codegen.
4 of the 5 are also implemented in LLVM-MLIR, since 'convergent' was
already there.
As a part of this, we also had to make sure that attributes were handled
properly for Call operation lowering, like we do for function
attributes.

[AArch64][GlobalISel] Add support for scalar variants of neon right shifts (#178207)
Neon intrinsics are able to operate on single-element vectors (e.g <1 x
i64>). However, LLVM doesn't allow single-element vectors, and instead
converts them to scalar values (e.g i64) in the frontend.
To get around this, the backend must place these scalar values onto an
fpr register bank, in order for the intrinsic to operate on the value as
a vector.
Previously, scalar right shift intrinsics were not legalising due to
misconfigured logic in AArch64LegalizerInfo, which treated non-vector
variants of these intrinsics as invalid.
This has been fixed so that the following can lower:
sqshrn
sqshrun
sqrshrn
sqrshrun
uqshrn
uqrshrn

[AArch64] Remove dead code emission in Pointer Authentication (#175989)
The AArch64 Pointer Authentication pass was emitting address
materialization instructions that were never used. These instructions
formed dead code and served no purpose in the final control flow.
Remove the unnecessary ADRP/ADD sequence from the Pointer Auth codegen
and update the corresponding test to reflect the simplified output.
This avoids generating dead instructions and keeps the PAUTH LR sequence
minimal and correct.

[VectorCombine] Fix crash when folding select of bitcast (#177183)
Fixes #177144. Nits appreciated.
The fold in question does the following transformation:
Before
```
%bc = bitcast <4 x i32> %src to <16 x i8>
%e0 = extractelement <16 x i8> %bc, i32 0
%s0 = select i1 %cond, i8 %e0, i8 0
%e1 = extractelement <16 x i8> %bc, i32 1
%s1 = select i1 %cond, i8 %e1, i8 0
...
```
After
```
%sel = select i1 %cond, <4 x i32> %src, <4 x i32> zeroinitializer
%bc = bitcast <4 x i32> %sel to <16 x i8>
%e0 = extractelement <16 x i8> %bc, i32 0
%e1 = extractelement <16 x i8> %bc, i32 1
...
```
If every select shares the condition and has 0 in the false branch, the
bitcast can be replaced with a select between the original vector and
`zeroinitializer`, followed by a bitcast. Then each `select(cond,
extelt(...), 0)` can be replaced with `extelt(...)`.
The crash happens when the condition is defined after the original
bitcast, because the bitcast is replaced with the select + bitcast, and
now the select references a condition not yet defined.

In some cases, we identify patterns as reductions, even though they can

Mark VPReductionPHIRecipe as not reading from memory & not having
side-effects, to clean them up.
We also need to remove ComputeReductionResult VPInstructions with
live-in arguments. This means there is actually no reduction, and we
need to fold it to the live in. Otherwise we would incorrectly reduce
the live-in.

[mlir][spirv] Add Pooling, Fourier Transform, and MatMul operations (#177585)
to TOSA Extended Instruction Set (001000.1)
This patch expands support for the TOSA Extended Instruction Set
(001000.1) to the SPIR-V dialect in MLIR. The TOSA extended instruction
set provides a standardized set of machine learning operations designed
to be used within spirv.ARM.Graph operations (corresponding to
OpGraphARM in SPV_ARM_graph) and typed with !spirv.arm.tensor<...>
(corresponding to OpTypeTensorARM in SPV_ARM_tensor).
The change introduces:
* Extending dialect plumbing for import, serialization, and
deserialization of the TOSA extended instruction set.
* The spirv.Tosa.*Pool* pooling operations, spirv.Tosa.MatMul, and
spirv.Tosa.*FFT* (Fourier Transform) operations from TOSA extended
instruction, each lowering to the corresponding OpExtInst.
* Verification enforcing that new convolution operations appears only
within spirv.ARM.Graph regions, operates on !spirv.arm.tensor<...>
types, and is well-formed according to the TOSA 001000.1 specification.
All these operations from TOSA 001000.1 extended instructions are
introduced: [parser, printer, verifier, and round-trip tests using
MLIR’s SPIR-V serialization/deserialization infrastructure are included.
This work aligns with Khronos SPIR-V TOSA specifications.

[LoopUnroll] Use branch probability in multi-exit loop unrolling (#164799)
This patch improves multi-exit loop unrolling by taking into account
branch probability and not only other exit being deopting one.
This implementation uses branch metadata directly because of unstable
state of BPI in this part of code (runtime unrolling invalidates the
state of the map and using BPI in my tests has caused errors).
If branch probability metadata are not present then the current deopt
heuristic is still used.

Previously, the helper functions had hardcoded validation that forced
all callbacks to reject these cases. This blocked intrinsics needing
custom validation (e.g., rounding mode checks). Now each callback
controls its own validation and returns `std::nullopt` when the fold is
invalid.

[mlir][dataflow ] Drop LLVM_DEBUG of DATAFLOW_DEBUG (NFC) (#177398)
We kept the DATAFLOW_DEBUG macro because when
LLVM_ENABLE_ABI_BREAKING_CHECKS is 0, the debugName in AnalysisState is
not defined, which prevents us from printing debug logs(In this case, we
define DATAFLOW_DEBUG(X) as an empty macro, so it won't print any logs).
Therefore, this PR only removes LLVM_DEBUG. We are now using LDBG, so
LLVM_DEBUG is no longer needed.

[lldb-dap] Improve test performance by removing negative assertions. (#178041)
Investigating some of the biggest slow downs during tests, the biggest
offender is 'wait_for_stopped' requiring a negative assertion around the
'stopped' event.
It currently waits for a negative predicate to fail before continuing.
This means it must wait for the full DEFAULT_TIMEOUT (50s) before the
test is allowed to continue.
To mitigate this, I added a new `collect_events` helper that will wait
for the given event to occur with the DEFAULT_TIMEOUT, then wait for a
quiet period (0.25s) before returning.
This greatly reduces the amount of idle waiting during tests.
Additionally, looking a the performance of individual test files,
`TestDAP_launch` is the slowest overall test. No individual test is that
slow, but the fact it has so many tests in the same file results in the
test harness waiting for that one file to finish.
To mitigate that, I split `TestDAP_launch` into individual test files
that run in parallel, reducing the runtime locally from over 2mins to
~5s.

[LifetimeSafety] Track transparent member functions for "all" GSL pointers (#177660)
Track transparent member functions (like data, begin, end, operator*,
etc) for all gsl::Pointer types and not just for STL types. This is a
change in semantics of `gsl::Pointer` annotations which now handles
specially **named** functions differently.
1. Tracking more methods that return pointers or references to objects
owned by the implicit object argument
2. Ensuring that methods like `data()`, dereference operators, and
begin/end iterators are properly tracked
The changes allow the analyzer to detect more cases where addresses of
stack memory are returned, particularly when working with GSL pointer
types that provide access to their underlying objects through methods
like `data()` or operators like `*` and `->`.
One particular idiom that is now detected is iterators involved in
range-based for-loops.
```cpp
View ContainerMyObjReturnView(Container<MyObj> c) {
for (const MyObj& x : c) { // expected-warning {{address of stack memory is returned later}}
return x; // expected-note {{returned here}}
}
for (View x : c) { // expected-warning {{address of stack memory is returned later}}
return x; // expected-note {{returned here}}
}
return Global;
}
```

[CSSPGO] Preserve pseudo-probe discriminators in cloneWithBaseDiscriminator (#178267)
In the O0 pipeline, `SampleProfileProbePass` runs before
`AddDiscriminatorsPass`. The
pseudo-probe pass stores probe IDs in the discriminator field using a
special encoding
(bits [2:0] = 0x7 as marker). When `AddDiscriminatorsPass` later
processes instructions
on the same source line, it calls `cloneWithBaseDiscriminator()` which
overwrites these
pseudo-probe discriminators with DWARF base discriminators, breaking
sample profile
matching.
This patch adds a check to `cloneWithBaseDiscriminator()` to detect and
preserve
pseudo-probe discriminators, similar to the existing check in
`cloneByMultiplyingDuplicationFactor()`.
In optimized pipelines (O1+), AddDiscriminators runs before pseudo-probe
instrumentation,
so this issue doesn't manifest. However, the fix makes the code robust
regardless of
pass ordering.

[InstCombine] Add combines for unsigned comparison of absolute value to constant (#176148)
This patch implements the following two peephole optimisations:
1. ``` abs(X) u> K --> K >= 0 ? `X + K u> 2 * K` : `false` ```;
2. If `abs(INT_MIN)` is `poison`, ```abs(X) u< K --> K >= 1 ? `X + (K -
1) u<= 2 * (K - 1)` : K != 0```.

[libc][math] Refactor logf16 to header-only shared math (#175408)
## Summary
Following the discussion in the RFC [1], Refactors logf16 to a
header-only shared math.
[1]
https://discourse.llvm.org/t/rfc-make-clang-builtin-math-functions-constexpr-with-llvm-libc-to-support-c-23-constexpr-math-functions/86450
## Implementation
- Moved the core logic and lookup tables from `generic/logf16.cpp` to
`__support/math/logf16.h`
- Updated `generic/logf16.cpp` to include the new header and call
`internal::logf16`
- Updated `CMakeLists.txt` and `BUILD.bazel` to reflect the dependency
changes and new header library

[EarlyIfConversion] Add analysis for data-dependent conditional branches(#174457)
Add infrastructure to identify conditional branches on values loaded from
memory. Such branches are likely to be harder to predict accurately since
branch history (probably) provides little useful information.
This analysis walks the def-use chain from the branch condition to find
loads that feed into it. Several cases are excluded from consideration:
- Loads from constant pools (predictable values)
- Dereferenceable invariant loads (loop-invariant)
- Branches with biased probability (null checks, etc.)
- Loads not "close in program time" to the branch (must be in the same
basic block with no intervening calls)
The analysis is disabled by default behind -enable-early-ifcvt-data-dependent.

This PR adds initial support for layout conflict resolution in XeGPU.
Layout conflict occurs when some op's use point expects a different
layout than what the op can currently provide. This conflict needs to be
resolved by adding certain other xegpu ops.
Initially, We only focus conflict handling at tensor desc use points.

[NFC] update doc comment on `setLoopEstimatedTripCount` (#178091)
See [this
discussion](https://github.com/llvm/llvm-project/pull/174896#issuecomment-3802361713)
prompted by PR #174896.
A 0-0 encoding in branch weights is invalid (the probability of an edge
is computed as a fraction where the denominator is the sum of the
weights and the numerator is its - the edge's - weight). So BPI actually
handles it as 1-1, which then results in raising the BFI of the loop
body that's meant to be cold.
The aforementioned PR addressed this, but didn't update the doc comment.

[mlir][memref] Define interfaces for ops that access memrefs at an index (#177013)
This commit defines interfaces for operations that perform certain kinds
of indexed access on a memref. These interfaces are defined so that
passes like fold-memref-alias-ops and the memref flattener can be made
generic over operations that, informally, have the forms `op ... %m[%i0,
%i1, ...] ...` (an IndexedAccessOpInterface) or the form `op %src[%s0,
%s1, ...], %dst[%d0, %d1, ...] size ...` (an IndexedMemCopyOpInterface).
These interfaces have been designed such that all the passes under
MemRef/Transforms that currently have a big switch-case on memref.load,
vector.load, nvgpu.ldmatrix, etc. can be migrated to use them.
(This'll also let us get rid of the awkward fact that we have memref
transforms depending on the GPU and NVGPU dialects)
While the interface doesn't currently contemplate changing element types
(enabling, for example, writing a bf16 => u16 update to be done in
place), future extensions to allow such transformations could be worth
exploring.
This commit only defines the interfaces so that it'll be easier to
review the design - the implementation is in a future PR.

This consists of the following changes:
* Merge several overloads of `VPlanTransforms::runPass` into a single
function
to avoid code duplication.
* Add helper macro `RUN_VPLAN_PASS` to capture the transformation name
and pass it to the helper above for printing.
* Add new `-vplan-print-after-all` option (somewhat similar to existing
`-vplan-verify-each`).
* Add two empty passes `printAfterInitialConstruction`/`printFinalVPlan`
so that initial/final
VPlans would be supported in `-vplan-print-after-all`
This follows the original future plans in

The return value of `getIsCounterPair(S)` was `std::pair<bool,bool>` but

It'd be better to name `getExecSkipCounterExistence` if
`std::pair<bool,bool>` would be resurrected in the future.

Modify llvm-gsymutil to work around invalid DW_AT_LLVM_stmt_sequence attributes. (#178034)
The DW_AT_LLVM_stmt_sequence attribute is an attribute that can be added
to a DW_TAG_subprogram DIE to uniquely identify the exact line tables
entries for a given function. This helps when we merge functions in the
same compile unit and end up with multiple sequences in the line table
that describe the same address range. Having this attribute on a
function allows us to select the right line table entries for a
function. This also helps us convert to GSYM and always get the line
tables right.
We have seen a large amount of errors when binaries have
DW_AT_LLVM_stmt_sequence attributes on functions but their values have
invalid .debug_line sequence offsets. When this would happen, the
conversion to GSYM would not emit any line table entries for that
function. This patch tries to use the DW_AT_LLVM_stmt_sequence attribute
when finding all line entries for a function, but it will fall back to
not using and requiring it to be correct. This ensures we always get the
most information in the GSYM even when DW_AT_LLVM_stmt_sequence values
are not valid. Others are working on fixing the compiler or LTO/Bolt
issues that cause invalid DW_AT_LLVM_stmt_sequence values to be in a
final executable, but this patch will help track and mitigate the issue.

[lld] Fill section gaps with trap instructions (#176845)
Fills unused parts of code segments with trap instructions instead of
zeroes. This is especially useful on x86-64 since 0x00 0x00 is a
two-byte instruction that performs a memory access. Benefits:
- Provides an explicit trap when executing invalid code.
- Required for security reasons when targeting LFI.
- Makes disassembling easier, especially without symbol information.
Previously an odd number of zero bytes between sections could cause a
disassembler to incorrectly disassemble the remainder of the program.

[clang][modulemap] Don't call translateFile (#176288)
In some cases `SourceManager::translateFile` ends up spending a lot of
time loading source locations from PCMs, significantly slowing down
module scanning. The actual requirements are that we use local FileIDs
for module maps so that we can compute affecting module maps, and that
there is only one FileID per module map per compiler instance. This
patch simply records the FileEntry to FileID mapping and reuses it when
needed.

We should only have branches from the origin remote when actually
running the workflow, but this makes the script easier to test locally
where I have branches from several different remotes.

[Clang][Sema] Avoid crash in overload diagnostics for invalid static deducing-this (#177783)
Fix #177741
Overload candidate diagnostics reserve a conversion slot for the object
argument. For static methods this slot does not correspond to a real
parameter, and for ill-formed declarations with an explicit object
parameter we could index past the parameter list and crash in assert
builds.
Use isExplicitObjectMemberFunction() when mapping conversion slots to
parameters and guard parameter-range computation to keep notes robust.

[lldb-dap] Adding more details to 'exceptionInfo'. (#176465)
In the exceptionInfo request I've added additional information for crash
data, instrumentation data and more detailed exception data.
For example, when UBSan is enabled, you now see additional information
in the exception stack trace about the detected issue:
<img width="1728" height="538" alt="Screenshot 2026-01-15 at 3 05 08 PM"
src="https://github.com/user-attachments/assets/b761af2c-90ac-4eb7-9926-3ab133f1b753"
/>
I included a new test for stopping at `lldb::eStopReasonInstrumentation`
and ensuring we have additional information reported.

[lldb] Add the ability to load ELF core file executables and shared libraries from memory (#177289)
This patch enables ELF core files to be loaded and still show
executables and shared libraries. Functionality includes:
- Load executable and shared libraries from memory if ELF headers are
available
- Create placeholder for missing shared libraries and executable.
Previously you just wouldn't get anything in the "image list" if no
executable was provided.

Add support for DW_FORM_GNU_ref_alt and DW_FORM_GNU_strp_alt. (#176056)
LLDB's DWARF parser didn't support parsing DW_FORM_GNU_ref_alt and
DW_FORM_GNU_strp_alt forms which would cause any file loaded by LLDB to
fail to parse any DWARF. Added support for parsing this information
only, not for actually finding the debug info reference to an alternate
file or a string in an alternate file. These extensions are used by DWZ
files which are present in some linux distros, so it will be good for
LLDB to just be able to parse these without emitting an error like:
(lldb) b bar

Create a new `IRBuilderBase::CreateAllocationSize` method to compute the
runtime size of an alloca as a Value*. This handles both static and
dynamic allocas by computing `ArraySize * ElementSize`, and using
CreateTypeSize to properly handle scalable vectors.
This de-duplicates code across multiple instrumentation and analysis
passes and increases consistency.

The alloca's explicit alignment (from getAlign()) is already optimally
correct; we don't need to derive alignment from the allocated type.

[clang][unittests] Fix linker error for DirectoryWatcherTest with CLANG_LINK_CLANG_DYLIB (#178455)
Move clangDirectoryWatcher from LINK_LIBS to CLANG_LIBS so it gets
replaced by clang-cpp when building with CLANG_LINK_CLANG_DYLIB=ON.
When using both CLANG_LINK_CLANG_DYLIB=ON and LLVM_ENABLE_LTO=Thin, the
test would fail with:
ld.lld: error: undefined symbol:
clang::DirectoryWatcher::create(llvm::StringRef, std::function<void
(llvm::ArrayRef
This happens because clangDirectoryWatcher was being linked as a
separate library alongside clang-cpp (which already contains
clangDirectoryWatcher), causing duplicate symbol issues with LTO.
The fix correctly categorizes:
- clangDirectoryWatcher → CLANG_LIBS (Clang library, bundled in
clang-cpp)
- LLVMTestingSupport → LINK_LIBS (LLVM library, always linked directly)

This enables the analysis to correctly track lifetimes through
non-trivial view types that require temporary binding due to having a
destructor.
This is fixed by handling `MaterializeTemporaryExpr` even for
lifetime-extended temporaries and fixing the flow of origins.

The latter is where we have problems right now.

[AArch64][Driver] Enable host supported features with march=native. (#177128)
Currently, march=native enables the base features implied by the host
system architecture, such as Armv8.2-A, Armv9-A, etc, rather than the
actual features supported by the host (e.g. crypto). This is suboptimal
as it generally leaves optional but supported features disabled.
This patch aligns the behaviour of march=native with mcpu=native by
using the latter's decoding logic to decode the former as well. This
means both options should enable a similar set of features. We also set
the target-cpu accordingly, so that march=native becomes a drop-in
replacement for mcpu=native.

Add to `ShapedTypeInterface` a new `tryGetNumElements()` API which
returns `std::optional<int64_t>` - returns `std::nullopt` on overflow
instead of UB, using `llvm::checkedMul` for proper overflow detection.
`getNumElements()` now uses this new API to assert on overflow.
Also fix `AffineExpr` canonicalization to avoid crashing on overflow
using `llvm::checkedMul`.

* Early return if we print a single line, and dedent the "else" that
handles multiple lines.
* Only convert lldb's short codes into ansi codes once.
* Rename a couple of variables where they could have either referred to
the visible text or the raw data with the ansi codes in.

order to catch more cases of extending loads. This type of code is
sometimes seen being generated by the loop vectoriser. For now I've
limited this to cases where the load is only used by the freeze, since
otherwise it leads to worse code in some X86 tests.

[Clang] avoid assertion in __underlying_type for enum redeclarations (#177984)
Fixes #177943
---
This patch addresses cases where `__underlying_type` is used with enum
redeclarations. The previously added assertion
(https://github.com/llvm/llvm-project/pull/155900) treated a missing
`int` on the referenced `EnumDecl` as an indicator of a _demoted
definition_, while this condition can also occur for redeclarations.

[Flang][OpenMP] Minimize host ops remaining in device compilation (#137200)
This patch updates the function filtering OpenMP pass intended to remove
host functions from the MLIR module created by Flang lowering when
targeting an OpenMP target device.
Host functions holding target regions must be kept, so that the target
regions within them can be translated for the device. The issue is that
non-target operations inside these functions cannot be discarded because
some of them hold information that is also relevant during target device
codegen. Specifically, mapping information resides outside of
`omp.target` regions.
This patch updates the previous behavior where all host operations were
preserved to then ignore all of those that are not actually needed by
target device codegen. This, in practice, means only keeping target
regions and mapping information needed by the device. Arguments for some
of these remaining operations are replaced by placeholder allocations
and `fir.undefined`, since they are only actually defined inside of the
target regions themselves.
As a result, this set of changes makes it possible to later simplify
target device codegen, as it is no longer necessary to handle host
operations differently to avoid issues.

[MLIR][OpenMP] Simplify OpenMP device codegen (#137201)
After removing host operations from the device MLIR module, it is no
longer necessary to provide special codegen logic to prevent these
operations from causing compiler crashes or miscompilations.
This patch removes these now unnecessary code paths to simplify codegen
logic. Some MLIR tests are now replaced with Flang tests, since the
responsibility of dealing with host operations has been moved earlier in
the compilation flow.
MLIR tests holding target device modules are updated to no longer
include now unsupported host operations.

Fix insert DBG_VALUE after terminator Failure for Hexagon (#173401)
This patch fixes an assertion failure on VLIW targets like Hexagon,
where a packet can contain both a terminator and a spill/copy. The
existing code did not look inside bundles, hence, it could leave a
transfer anchored on a terminator. When LiveDebugValues later
attempted to insert a DBG_VALUE after that packet, it hit:
Assertion `!TR.TransferInst->isTerminator() && "Cannot insert
DBG_VALUE after terminator"' failed
The change switches to instr_iterator and walks each packet with
getBundleStart/getBundleEnd. Packets containing a terminator are skipped
for insertion; non‑terminator ops in other packets are still processed
normally. This avoids illegal insertion points while keeping spill/copy
tracking intact.

[GlobalISel] Provide a fast path for ResetMachineFunctionPass when the function is empty (#177341)
As part of https://github.com/llvm/llvm-project/pull/174746 I
encountered a compile time regression due to ResetMachineFunction
performing full resets on empty functions. In normal operation, this
behaviour is not likely to impact compile time, as the pass is only
inserted when using GlobalISel.
https://github.com/llvm/llvm-project/pull/174746 includes GlobalISel
passes in the SDAG pipeline (only on AArch64) and skips them if a given
function is not optnone surfacing this. By checking if the
MachineFunction is empty we can perform a more lightweight reset that
just sets the required flags, reducing the impact of this change.

[AArch64] Use GISel for optnone functions (#174746)
Currently, when SDAG is run on AArch64 and an `optnone` function is
encountered, the selector is chosen as FastISel. AArch64 makes use of
GlobalISel at O0 and this patch aims to align `optnone` with this
functionality.
A flag is exposed to enable this functionality for a given backend but,
as AArch64 is currently the only backend I could find using GlobalISel
at O0 this is the only one with it implemented. This flag is set when
the target supports GlobalISel & GlobalISel hasn't been forced by the
user, the target machine or by being at an optimisation level lower than
`EnableGlobalISelAtO`.
If this happens, the GlobalISel passes are included as shown in
`llvm/test/CodeGen/AArch64/O3-pipeline.ll` and skipped by IRTranslator
for functions not marked as `optnone`.
In updating the tests based on this functionality, I found some unused
check lines or run lines that mixed SDAG with GlobalISel pass names
which have been fixed.

Recursive types can cause re-entrant mapper emission. The mapper

registered in the ModuleTranslation mapping table. Reuse and register it
to break the recursion. Added offloading test.

mechanism. However, recent experiments with larger kernels have shown
that this pass is very expensive in terms of compile time (see below).
This prompted us to create a new pass that does not rely on `WarpOp`
based distribution. This PR adds the initial infra to move away from the
old way and align Wg To WI distribution with Wg to Sg distribution. New
pass also uses context-aware type conversion based on XeGPU layouts to
distributed vector types from SG to WI.
This PR adds the following changes:
* SG to WI distribution pass based on context-aware type conversions
using `OpConversionPatterns`
* Test pass for testing individual patterns
(`TestXeGPUSgToWiDistributeExperimental`)
* `XeGPUSgToWiDistributeExperimentalPass` which will eventually replace
`XeGPUSubgroupDistribute`

[libc++] Fix `__split_buffer_size_layout` bugs (#178341)
As `__split_buffer` doesn't have any unit tests, and because #139632
disassociated adding `__split_buffer` support for both pointer-based and
size-based layouts from its `vector` counterpart, libc++ had no way to
expose `__split_buffer_size_layout` bugs until the size-based vector
patch integrated #139632. This commit fixes the two problems that were
identified while working on #155330.

Therefore, when it's in the post-fixup phase,
`DebugObject::awaitTargetMem` will fail with _"std::future_error: No

[GlobalISel] Rewrite binop_left_to_zero using MIR Patterns (#177924)
Following 2d87319f06ef936233ba6aaa612da9586c427d68, this PR rewrites the
`binop_left_to_zero` rule using MIR Patterns.
The new pattern uses `GIReplaceReg` in the apply clause. According to
[MIRPatterns.rst](https://github.com/llvm/llvm-project/blob/5b4a5cf51f37cb42c5e0bdb22b43acde137281c8/llvm/docs/GlobalISel/MIRPatterns.rst?plain=1#L222),
`GIReplaceReg` checks `canReplaceReg`, so the new apply pattern is
equivalent to the old `matchOperandIsZero` implementation.
Added tests for all the opcodes covered by this rule `(G_SHL, G_LSHR,
G_ASHR, G_SDIV, G_UDIV, G_SREM, G_UREM, G_MUL)`.

This pass optimizes acc.firstprivate_map operations generated during
OpenACC recipe materialization when acc.firstprivate is materialized
into the mapping and a private allocation inside region. The
optimization applies to scalar variables of trivial types (integers,
reals, logicals) as long as they are not optional.
The pass hoists loads from the firstprivate variable to before the
compute region, converting the firstprivate copy to a pass-by-value
pattern. This eliminates the need for runtime copying the firstprivate
variable since only its value is needed for initializing private copies.

[lldb] Move ValueImpl and ValueLocker to ValueObject, NFC. (#178573)
This patch moves ValueImpl and ValueLocker to ValueObject.{h,cpp}. This follows the example set in TypeImpl/SBType, where we have something that SBType uses internally that needs to be exposed in the layer below. In this case, SBValue uses ValueImpl, which wraps ValueObject. The wrapper helps avoid bugs, so we want to keep it, but the script interpreter needs to use it and said interpreter is conceptually *below* the SB layer...which means we can't use methods on SBValue.
This patch is purely the code motion part of that, future patches will actually make use of this moved code.

When we're hoisting a spill to another block, and storing one of its

that sibling value is alive at the insertion point. Otherwise, we might

[lldb] Add conversions for SBValueList and SBValue to the python bridge. (#178574)
This patch adds support for:
- PyObject -> SBValueList (which was surprisingly not there before!)
- PyObject -> SBValue
- SBValue -> ValueObjectSP using the ScriptInterpreter
These three are the main remaining plumbing changes necessary before we can get to the meat of actually using ScriptedFrame to provide values to the printer/etc. Future patches build off this change in order to allow ScriptedFrames to provide variables and get values for variable expressions.

[lldb] [disassembler] chore: add GetVariableAnnotations to SBInstruction api (#177676)
## Description
Contribution to this topic [Rich Disassembler for
LLDB](https://discourse.llvm.org/t/rich-disassembler-for-lldb/76952),
this part.
```
The rich disassembler output should be exposed as structured data and made available through LLDB’s scripting API so more tooling could be built on top of this
```
----
This pr replaces #174847
As was suggested in [this
comment](https://github.com/llvm/llvm-project/pull/174847#issuecomment-3757015552),
implement access to variable annotations from `SBInstruction` class
itself.
Notes:
- :white_check_mark: did run black formatter on the python file;
## Testing
Run test with
```sh
./build/bin/lldb-dotest -v -p TestVariableAnnotationsDisassembler.py lldb/test/API/functionalities/disassembler-variables
```
all tests (9 existing + 1 newly added) are passing

[analyzer] Fix [[clang::suppress]] for tricky template specializations (#178441)
The code assumed that taking the lexical parent decl context of a node
and traversing it will eventually visit the node itself. While this is
certeanly true for most AST constructs, template specializations (aka.
instantiations) might inject their AST to surprising lexical parents,
depending on when they get instantiated.
This means that just taking the lexical parent of a template
specialization might land us on some AST node that won't contain (thus
visit) the definition, and consequently, miss the Suppress attribute...
To fix this, we must take special care for template specializations. For
a regular instantiation select the primary template (that has the definition).
For an instantiation coming from a partial specialization, pretend if it
was the partial specialization instead.
Once we canonicalize to the primary template/partial specialization
definition, the usual "walk the lexical parents" logic covers the rest
as usual.
