[CIR] Add floating-point type descriptors to decodeFixedType (#194483)
`decodeFixedType` in `CIRGenBuiltin.cpp` only handled `Void`, `Integer`, `Vector`, and `Pointer` IIT descriptor kinds. Any target builtin whose intrinsic signature includes a floating-point type (e.g. `__builtin_ia32_rsqrtps` → `<4 x float>`) hit the default `errorNYI` path, which returned `VoidType`. `VectorType::get(VoidType, N)` then tripped the MLIR type verifier assertion.
Adds `Half`, `BFloat`, `Float`, `Double`, and `Quad` cases.
Found while building the Eigen test suite with CIR — this was crashing 21 of 135 test files.

[SandboxIR][SandboxVec] Remove score tracking from Region, add RegionWithScore (#190293)
Up until now the `Region` class contained a `ScoreBoard` and was
tracking instruction costs by default. However, design-wise the Region
is a generic IR-level structure and should be independent from score
tracking.
So this patch removes the score tracking capability from the base
`Region` class and creates a separate `RegionWithScore` derived class
for that. The new class is placed in the vectorizer directory because
the score tracking is meant for the vectorizer.
Should be NFC.

[flang][CUDA] Only apply implicit managed attribute when CUDA Fortran is enabled (#195353)
The implicit-managed tagging added in #175648 was intended for CUDA
Fortran allocatables. However, the gate was just
LanguageFeature::CudaManaged, so the tagging also fires on
non-CUDA-Fortran translation units when -gpu=mem:managed is in effect.
This patch adds a LanguageFeature::CUDA check so the implicit tagging
only fires for CUDA Fortran TUs (driver-set -fcuda or .cuf/.CUF source).
Adds a regression test that bbc -gpu=managed without -fcuda on a .f90
source must not produce any cuf.* ops or #cuf.cuda<managed> attributes.

[clang][NFC] Mark CWG2785 as implemented and add a test (#195547)
[CWG2785](https://wg21.link/cwg2785) clarifies that a
*requires-expression* is never type-dependent, it always has type
`bool`. That means that in a snippet like this:
```cpp
void g(void *);
template <typename T>
void f() {
g(requires { T(); });
}
```
The call to `g` should be diagnosed as invalid (`bool` is not
convertible to `void *`) even if the template is never instantiated.
Clang does the right thing since version 10:

This PR adds a flag that downgrades some of the semantic constraints on
C_LOC so that it can be used more like LOC. Without the flag behavior is
unmodified, with the flag the constraint that the address be object
pointer or target is removed. There are other constraints we might
consider relaxing, but I think this is a start.

[MLIR][AMDGPU] Add amdgpu.global_transpose_load op for gfx1200+ global memory transpose loads (#195287)
Adds a new `amdgpu.global_transpose_load` op to the AMDGPU dialect that
wraps the `global_load_tr` family of instructions introduced in RDNA4
(gfx1250+). Each thread reads a column of a matrix from global memory
and receives the corresponding transposed row in its result register.
The op is kept separate from the existing `amdgpu.transpose_load` (which
targets LDS via `ds_read_tr` on gfx950+) because the two variants target
different GPU architecture families, have different chipset
requirements, and differ in their valid (element size, num elements)
combinations — in particular the 16-bit case produces a 128-bit
(8-element) result via `global_load_tr.b128` rather than the 64-bit
(4-element) result from `ds_read_tr16.b64`.
Lowering to the existing ROCDL `global.load.tr{4,6,.}.b{64,96,128}`
intrinsics added for gfx1200+.

[mlir][acc] Introduce privatization operations for codegen (#195273)
This change adds codegen-oriented operations for representing
private-variable storage and materializing the storage that a particular
parallel execution actually uses.
The two operations are meant to be used together:
- acc.privatize introduces an abstract handle for the privatized
storage,
including the parallel levels that determine the ultimate size of the
storage needed. Which parallel levels apply can be stated when that
structure is known, or omitted so the same representation can be refined
later as launch and loop parallelism are decided.
- acc.private_local takes that handle and yields the concrete storage
for the current execution context(for example the slice that corresponds
to this gang or worker).

[SelectionDAG] Look through FREEZE in getCopyToRegs when checking isZExtFree (#195285)
When a narrow load i8 or i16 is frozen and its value crosses a basic
block, `getCopyToRegs` emits `any_extend` instead of `zero_extend`
because `isZExtFree` can't see through the `ISD::FREEZE` node.
Example: https://godbolt.org/z/MYvjq8vPM contains an redundant `and w11,
w11, 0xff`
```
ldrb w11, [x10], #1
cmp w11, #32
b.lo .LBB0_1
and w11, w11, #0xff
```
Fix this by passing the incoming node to the freeze to `isZExtFree`
instead.

[lldb] Use (_d).pyd as Python extension suffix on Windows (#195262)
The current Windows x86_x64 installer ships a `_lldb.abi3None` in
`lib\site-packages\lldb\native`. This will cause errors when trying to
import LLDB in Python.
We always use `.abi3{SHLIB_SUFFIX}` as the Python extension suffix in
`get-python-config.py`. On Windows(-msvc), this won't result in the
correct path. `SHLIB_SUFFIX` is not defined there.
The recognized extensions are:
```console
> python -c "import importlib.machinery;print(importlib.machinery.EXTENSION_SUFFIXES)"
['.cp314-win_amd64.pyd', '.pyd']
> python_d -c "import importlib.machinery;print(importlib.machinery.EXTENSION_SUFFIXES)"
['_d.cp314-win_amd64.pyd', '_d.pyd']
```
The first one is equal to `sysconfig.get_config_var("EXT_SUFFIX")`.
I changed `get-python-config.py` to use `.pyd` if `SHLIB_SUFFIX` is
undefined. This is currently hardcoded. It seems like cpython has some
contract that the last suffix in `EXTENSION_SUFFIXES` is the untagged
one ([from this
test](https://github.com/python/cpython/blob/f2c7c0d2b799c927d9a78e87e4a640d3f9b0356c/Lib/test/test_traceback.py#L5225-L5232)).
But I haven't found any documentation on that.

[lldb-dap] Fix core file stop reason overridden to "entry" (#195352)
# Summary:
There's a behavior change on core file stop reason
It used to report the actual crash (stop) reason:
- reason: "exception" (reflecting the actual crash signal/exception)
- description: crash signals, eg."signal SIGSEGV"
However, the stopped event now always reports:
- reason: "entry"
- The crash reason is lost
## Root Cause
1. `bd0efcaa34b1` (Oct 31, 2025) — "[lldb-dap] Correctly trigger 'entry'
stop reasons"
This commit changed CreateThreadStopped in `JSONUtils.cpp`:
Changed `body.try_emplace("reason", "entry")` to `body["reason"] =
"entry"`, and this will overwrites it unconditionally.
2. `51e5b6c6acc0` (Feb 3, 2026) — "Migrating 'stopped' event to
structured types"
Rewrote the stopped event with an if/else that completely skips the stop
reason switch when on_entry=true:
```
if (on_entry) {
body.reason = eStoppedReasonEntry; // thread stop reason never inspected
} else { ... }
```
## The Underlying Design Issue
`stop_at_entry` serves double duty in AttachRequestHandler.cpp:40-41:
```
if (!args.coreFile.empty())
dap.stop_at_entry = true;
```
This flag both (a) `prevents process.Continue()` from being called
(correct for core files) and (b) tells `SendThreadStoppedEvent` to use
reason "entry" (wrong for core files — should report the actual crash
reason).
# Test Plan:
Added DAP test to check for stop reasons
Launch a coredump debug session with local build lldb-dap and observe
the stop reason

[MLIR][LLVM] Add variant part debug info support (#195321)
#### Summary
This PR extends the MLIR LLVM dialect debug-info attributes to represent
DWARF variant parts, discriminators, and per-alternative discriminator
values.
The change adds `identifier` and `discriminator` support to
`DICompositeTypeAttr`, allowing MLIR to model `DW_TAG_variant_part`
metadata that LLVM IR already supports. It also broadens
`DIDerivedTypeAttr`'s `extraData` field from `DINodeAttr` to a verified
polymorphic `Attribute`, supporting both debug-info nodes and integer
constants used by variant alternatives.
#### Details
- Add `identifier` and `discriminator` fields to `DICompositeTypeAttr`,
bytecode serialization, LLVM IR import/export, C API bindings, and Flang
call sites.
- Change `DIDerivedTypeAttr.extraData` to accept either `DINodeAttr` or
`IntegerAttr`, with verifier coverage for invalid attribute kinds.
- Preserve integer bit width when importing
`ConstantAsMetadata(ConstantInt)` into MLIR.
- Add parse/print, verifier, LLVM IR import/export, and C API test
coverage for variant-part debug info.

3. CSPGO flags were only passed for LLD. Now pass to the linker with

[CIR] Implement devirtualized member function calls (#195106)
Implement the devirtualization logic in
emitCXXMemberOrOperatorMemberCallExpr that was previously guarded by
MissingFeatures::devirtualizeMemberFunction(). This enables the compiler
to emit direct calls instead of virtual dispatch when the dynamic type
can be statically resolved (e.g., final classes, local variables of
known type).
This fixes the 'devirtualized destructor call' errorNYI in
CIRGenExprCXX.cpp, which is point 5 of #192330.
The implementation follows OGCG: use getDevirtualizedMethod() to check
if devirtualization is possible, then getCorrespondingMethodInClass() to
find the target method. For destructors, use getAddrOfFunction() instead
of getAddrOfCXXStructor() since the devirtualized callee may differ from
the original.
Fixes point 5 of #192330.

[libc++] Add `__exchange` as a C++11 utility (#187953)
`std::exchange` is helpful for simplifying move operations because we
can couple the resetting component with the move operation. This both
halves the number of necessary lines for each move, and also ensures we
haven't forgotten to reset the moved-from object. Since `std::exchange`
is a C++14 feature, we'll need to use `__exchange` for anything that's
from C++11.
This commit also applies `std::__exchange` to a some trivial use-cases
to show its utility. Applying this project-wide requires a census over
all of our types. It's hoped that this will start a community-wide
clean-up that happens over time.

[TableGen] Fix null-pointer assert in RecordVal::setValue on failed cast (#195492)
When setValue's getCastTo failed, Value was overwritten with nullptr
instead of being left untouched.
The "no value set" sentinel is UnsetInit, not nullptr, so a downstream
RecordResolver::resolve that called isa<UnsetInit>(RV->getValue()) would
assert on the null pointer when a later def tried to resolve an
expression referring to that field.
Compute the cast into a local and only commit to Value on success, so a
type-incompatible override (e.g. redeclaring an int field as string in a
subclass) reports the existing "is incompatible" error and exits cleanly
instead of aborting.

clang: Use Triple::isCompatibleWith to match OpenMP arguments (#195724)
Previously this was performing an exact string comparison
of the triple. Use the triple predicate so that in the future
amdgpu triples without a subarch will be considered compatible
with triples that do. This preserves compatibility with existing
uses without a subarch.
Note that if you swap the triples, there's an assert in
buildCompilerRTBasename but this appears to be a pre-existing
issue I can reproduce without the patch (but I can't reproduce
on godbolt for some reason).

[XeGPU][Transform] Add XeGPU array length optimization patterns. (#194062)
This PR adds array_length optimization patterns and a test pass.
These patterns are used as part of the `XeGPUPeepHoleOptimizerPass`.
These patterns optimize `xegpu.create_nd_desc`, `xegpu.load_nd` and
`xegpu.prefetch_nd`
operations by introducing the array_length attribute when the FCD
(fastest changing
dimension) is larger than the subgroup size (i.e., 16).
The transformation updates:
1. `tensor_desc` type to use array_length and reduced FCD: `shape<32x32>
→ shape<32x16, array_length=2>`
2. `load_nd/prefetch_nd` result vector shape to match register layout:
`vector<32x32> → vector<64x16> (register layout)`
3. `vector.extract_strided_slice` operations to account for memory vs
register layout difference
Also, change XeGPU verifier to support 2D stacked layout (array blocks
stacked vertically).

[clang] Add formal linkage to textual AST dump (#194600)
This PR adds formal linkage (external, module, internal) to the textual
AST dumps. The motivation is to inform users (including ourselves) what
Clang thinks the linkage is, and to prevent situations where `extern` is
mistaken for an indication of external linkage (see #192116 for an
example).
The wording around linkage is known to be defective, but that's the best
we have: [[basic.link]](https://eel.is/c++draft/basic.link) paragraphs 3
through 7.
There are enough changes in this PR, so I decided to defer adding formal
linkage to JSON dumps to another PR.

[docs] Document the usage of operators on RVV sized types (#194979)
We have existing support in clang for operator overloading on RVV
builtin types when those types are sized. This can be achieved through a
combination of the -mrvv-vector-bits=N command line (to communicate
exact VLEN to the compiler) and the riscv_rvv_vector_bits attribute on
the types themselves. We have fairly complete test coverage for this in
clang/test/CodeGen/RISCV/rvv-vls-*.ll.
Our documentation did not reflect this reality, so this patch updates
the documentation to match the actual support.
Patch written by Claude, with minor sanity checking by me.

[lldb] IRForTarget::UnfoldConstant should return an llvm::Error (#195322)
UnfoldConstant returns a boolean and logs errors to a stream. However,
the prevailing pattern is to return an Error object and let the caller
decide what to do with it.
Currently, these error messages are dumped out to stdout when LLDB
encoutners an issue. I decided not to change that behavior with this
commit to keep it simple and self-contained.
I also reformatted and simplified some code in UnfoldConstant where it
was relatively easy.

This patch enables inline history tracking in the ModuleInliner to
address this issue.
The minsize attribute in the test case lowers the threshold for the
mutually recursive functions, ensuring the bug reproduces in pass
isolation.

[InlineOrder] Fix assertion failure in CostBenefitPriority (#195564)
InlineCost::getStaticBonusApplied() triggers an assertion failure
if the CostBenefitPriority constructor calls it when
IC.isVariable() is false. This is because
getStaticBonusApplied() expects isVariable() to be true.
Unconditionally populating CostBenefit also incorrectly prioritizes
a NeverInline candidate with a cost-benefit pair over other
valid variable-cost sites.
This patch fixes the crash and the sorting issue by calling
getStaticBonusApplied() and populating CostBenefit only when
IC.isVariable() is true. For AlwaysInline and NeverInline costs,
CostBenefit is explicitly set to std::nullopt.

-----------
Add named posix semaphore lifetime operations on linux (#192278)
This implements the second part of #190847
Specifically, this pr adds `sem_open`, `sem_close`, and `sem_unlink` for
posix semaphore on linux.
https://pubs.opengroup.org/onlinepubs/9799919799/functions/sem_open.html
https://pubs.opengroup.org/onlinepubs/9799919799/functions/sem_close.html
https://pubs.opengroup.org/onlinepubs/9799919799/functions/sem_unlink.html
Since it targets on linux implementation, two extra things are added:
1. add system call wrappers for `mmap`, `munmap`, `link`, `unlink`, and
`ftruncate`. Those are necessary for the implementation of semaphore on
linux. Wrappers is added based on the refactor proposal:
https://libc.llvm.org/dev/syscall_wrapper_refactor.html.
2. refactor the previous semaphore implementation, put it under `linux/`
since its based on linux.

[DWARFLinker] Emit DW_IDX_parent in the accelerator table (#195403)
.debug_names entries produced by the parallel linker were always emitted
with std::nullopt for ParentDIEOffset, resulting in a missing
DW_IDX_parent. The classic linker emits it via
DWARF5AccelTableData::getDefiningParentDieOffset on the output DIE tree.
The parallel linker can't use the same approach because the records are
saved during cloneDIE, before the output DIE has been linked into its
parent, so DIE::getParent() is nullptr at that time time. Fix that by
computing the parent offset from the input-side DIE tree instead. We
look up InputDieEntry's parent via getParentIdx, skip parents marked
DW_AT_declaration, and translate them to the output offset through
CompileUnit::getDieOutOffset. Since no real DIE can live at offset 0, we
can use that to unambiguously mark input DIEs that were not cloned into
this CU's plain DWARF (e.g. routed only into the artificial type unit)
and is treated as "no parent".
Only compile-unit accelerator entries are covered. Type-unit entries
(artificial type unit) still emit no DW_IDX_parent, tracked by a TODO.

[flang][OpenMP] Detect DSA conflicts in nested loop constructs (#195323)
Follow-up to https://github.com/llvm/llvm-project/pull/194961
The fix from PR194961 did not detect explicit/predefined DSA conflicts
on an iteration variable in a nested loop construct. For example, in a
testcase inspired by Fujitsu 0165_0035.f90:
```
!$omp parallel do private(i) shared(j)
do i=1,1
do j=1,1
!$omp parallel do default(none) shared(k)
do k=1,1
end do
!$omp end parallel do
end do
end do
```
the "shared(k)" was not flagged as incorrect.
Adjust the fix to traverse the host-association chain until the symbol
from the DSA clause is found.

[SandboxIR][Tracker] Support nested checkpoints (#191097)
This patch implements nested checkpointing, i.e., you can now save the
IR state more than once and revert more than once.
For example, after two saves: save(1) and save(2), a revert() will bring
you back to the IR state of save(2), one more revert will bring you back
to the IR state of save(1).

initialization, but zero-initializing it satisfies the compiler and
avoids the `-Werror=maybe-uninitialized` error.

[NFC][asan] Re-use ErrorGeneric::shadow_val (#195684)
It's done to reduce code size, as additional load on reporting is
negligible.
This requires change in ErrorGeneric constructor, to now we skip partial
shadow only if next one has a better value.
Before shadow_val was either `0x[a-f].` or 0.
Now it may be partial granule as well.
However it's NFC as `0 < shadow_val < ASAN_SHADOW_GRANULARITY` does not
affect reporting outside of `CheckPoisonRecords`.

[RFC][IR] Support vector splats in `ConstantPointerNull` (#195486)
This PR allows `ConstantPointerNull` to represent both scalar pointer
nulls and fixed or scalable vector splats of pointer nulls. This change
first aligns with the native splat behavior of `ConstantInt` and
`ConstantFP`, and second, makes it easier to eventually change the
semantics of `ConstantPointerNull` to represent a semantic null pointer
instead of a zero value, which is what it represents today.

[NVPTX] Fix for LTO dwarf emission when multiple CUs with a mix of DebugDirectivesOnly and NoDebug (#190371)
Only emit the initial .loc dwarf directive if the CU requires debug
information. When a module contains multiple CUs where one is
DebugDirectiveOnly and the rest are NoDebug, we attempt to emit dwarf
for the NoDebug compile units leading to an assertion when calling
emitDwarfFile0Directive when in getOrCreateDwarfCompileUnit.
I added a lit test for this case which used to assert.

[libcxx] Remove ASan container overflow checks for SSO strings (#194208)
Essentially a revert of #79536, although manual given how much the code
has changed.
Doing container overflow checks on SSO strings is fundamentally unsound
due to how they interact with compiler optimizations within LLVM, which
assume that the entire object is dereferencable when it is live. LLVM
can sometimes insert speculative loads that will create false positives
when they try and load a partially filled SSO buffer. This was
previously prevented using inline asm barriers within std::string
itself. However, this can also manifest in other ways, with the
motivating example for the revert being GlobalOpt inserting a
speculative load of a std::variant containing a SSO std::string, causing
an ASan failure.

[compiler-rt] Add MSVC CRT flags to ASan coverage test (#195719)
The ASan coverage test also links clang_rt.profile because it uses
-coverage. On Windows MSVC, this can fail if the test is linked with the
static CRT but clang_rt.profile was built with the dynamic CRT.
For example, a profile runtime that uses /MD may reference DLL CRT
symbols
such as __imp_* symbols. Add the same dynamic CRT flags directly to this
one test on Windows MSVC so it keeps linking when clang_rt.profile
changes.

[IR] Add elementwise modifier to atomicrmw (#189517)
This PR implements the IR side modifications of [[RFC] Add elementwise
modifier to atomicrmw](https://discourse.llvm.org/t/rfc-add-elementwise-modifier-to-atomicrmw/90134).
Design Decisions:
- In the IR, the current atomicrmw record layout looks like: [ptrty,
ptr, valty, val, operation, vol, ordering, syncscope, align]. To encode
elementwise, I decided to pack it into the operation field, which also
contains the math op (i.e. fadd, fmin, add etc...). I could have changed
the record structure, but that would be slightly more complicated.
- elementwise vector atomics can be vectors of integers because we can always scalarize legally
- elementwise vector atomics need to have power of 2 size. We can potentially remove this restriction later.

[MLIR][Python] Add `ConditionallySpeculatable` interface and `Pure` specifier (#195505)
This PR brings two features: the `ConditionallySpeculatable` op
interface and the `Pure` specifier for Python-defined ops.
The result is that you can mark an op as pure like:
```python
class PureOp(
TestPure.Operation,
name="pure",
traits=[Pure] # just like in the ODS!
):
a: Operand[IntegerType[32]]
b: Operand[IntegerType[32]]
res: Result[IntegerType[32]] = infer_result()
```
Then this op is both `NoMemoryEffect` and `AlwaysSpeculatable`.

This commit makes two changes to the naming conventions for SPS CI
symbols:
1. The orc_rt_sps_ci_ prefix is replaced with orc_rt_ci_sps_ (for SPS
wrapper functions) and orc_rt_ci_ (without the "sps_" suffix) for data
symbols.
2. The _sps_wrapper suffix is dropped from wrapper functions, since the
prefix now distinguishes between SPS-wrappers and data symbols.

[PGO][ICP] Prevent indirect call promotion to functions with incompatible target features (#192142)
Profile-driven indirect call promotion was promoting indirect calls to
functions requiring advanced CPU features (e.g., AVX512) even when the
caller function did not support those features. When these promoted
calls were subsequently inlined, it could lead to invalid IR and
backend crashes during instruction selection because the target CPU
could not handle the advanced instructions.
This patch addresses the issue by adding a target feature
compatibility check to `llvm::isLegalToPromote` in
`CallPromotionUtils.cpp`. If the callee requires target features
(prefixed with `+`) that are not present in the caller's target
features, the promotion is skipped. By centralizing this check in
`isLegalToPromote`, we protect all passes relying on this utility
(such as `SampleProfileLoader` and `IndirectCallPromotion`) from
promoting to incompatible targets. This also prevents incorrect
inlining of `always_inline` functions that would otherwise be promoted
via indirect calls and then inlined.

[MLIR] Fix offload map metadata order (#195346)
This fixes one part of
https://github.com/llvm/llvm-project/issues/195333.
There are two different semicolon-field orders in
offload/include/Shared/SourceInfo.h:
1. Per-map strings (`map_var_info_t`): first field is the mapped name,
second
is the file path:
```
/// Type alias for source location information for variable mappings with
/// data layout ";name;filename;row;col;;\0" from clang.
using map_var_info_t = void *;
```
2. `ident_t` region strings: first field is the file path, second is the
function name:
```
/// The ident structure that describes a source location from kmp.h. with
/// source location string data as ";filename;function;line;column;;\0".
struct ident_t {
```
`SourceInfo` reflects that with two constructors: `SourceInfo(const
ident_t *)`
parses `getSubstring(0)` as the filename field and `getSubstring(1)` as
the
name (function); `SourceInfo(const map_var_info_t)` uses
`getSubstring(0)` for
the map name and `getSubstring(1)` for the filename path.
`OpenMPIRBuilder::getOrCreateSrcLocStr(FunctionName, FileName, line,
col)`
always builds the same wire shape: the second parameter is emitted
first,
then the first i.e. ;FileName;FunctionName;line;col;.
Clang passes arguments accordingly in two places:
1. per-map metadata (`emitMappingInformation`):
Calls `getOrCreateSrcLocStr(FileName, ExprName, ...)`
so the buffer is ";expr;path;…", matching `map_var_info_t` and
`getNameFromMapping`.
2. ident / update location (`emitUpdateLocation`):
Calls `getOrCreateSrcLocStr(FunctionName, FileName, ...)` so the buffer
is
";file;function;…", matching ident_t.
MLIR previously called the same helper in only the ident-like way for
both
uses which is why we see file paths in the map name slot.
I would have preferred if we can keep the same order in both cases. But
I am not
aware of the history of why it was done like this. I have instead fixed
it by adding
`ForOffloadMap` to `createSourceLocStrFromLocation` so mapping uses the
same
argument order as Clang's `emitMappingInformation`, while ident-style
callers
keep the existing order.
Adjusted a test accordingly.

[clang][bytecode] Don't evaluate bound member function expressions in new constant interpreter (#194851)
**Problem:**
A crash is triggered by clangd's hover feature when using C++23 and the
new bytecode interpreter, which calls `Expr::EvaluateAsRValue()` to
attempt constant folding on an expression under the cursor, even when it
is not a valid constant expression.
Tested versions: 22.1.3, Trunk (x86_64-pc-linux-gnu)
**How to reproduce:**
```cpp
struct S { void f(); };
void g() { S s; s.f(); }
```
Running `clangd --check=repro.cpp`
(with `compile_flags.txt` containing `-std=c++23
-fexperimental-new-constant-interpreter`)
will crash.
`Assertion ItemTypes.back() == toPrimType<T>() failed.`
You can observe the same crash by hovering over STL iterators like
`vec.begin()`.
**Relevant Stack Trace:**
```text
#8 clang::interp::InterpStack::pop<MemberPointer>()
#9 clang::interp::EvalEmitter::emitRet(PrimType, SourceInfo)
#10 clang::interp::Compiler<EvalEmitter>::visitExpr(Expr const*, bool)
#11 clang::interp::EvalEmitter::interpretExpr(Expr const*, bool, bool)
#12 clang::interp::Context::evaluateAsRValue(State&, Expr const*, APValue&)
#13 EvaluateAsRValue(EvalInfo&, Expr const*, APValue&)
#14 clang::Expr::EvaluateAsRValue(EvalResult&, ASTContext const&, bool) const
#15 clangd::(anon)::printExprValue(Expr const*, ASTContext const&)
#16 clangd::(anon)::printExprValue(SelectionTree::Node const*, ASTContext const&)
#17 clangd::getHover(...)
```
*Basically: `textDocument/hover` → `getHover` → `EvaluateAsRValue` → new
constant interpreter → `MemberPointer` type mismatch on stack pop.*
When `Compiler<Emitter>::VisitMemberExpr()` encounters a non-static
`CXXMethodDecl` member (a bound member function expression such as `s.f`
in `s.f()`), it falls through to `visitDeclRef()`. This pushes a `FnPtr`
onto the interpreter stack. However, the caller expects a
`MemberPointer`, causing an assertion failure in `InterpStack::pop()`:
**Fix:**
* In `VisitMemberExpr()`, bail out early (`return false`) when the
member is a non-static `CXXMethodDecl`, before reaching
`visitDeclRef()`. This causes `EvaluateAsRValue()` to report failure
gracefully rather than crashing. Bound member function expressions
(`s.f`) are not valid constant expressions, so returning `false` should
be semantically correct.
**Testing:**
* Added AST unit test
(`EvaluateAsRValue.FailsGracefullyOnBoundMemberExpr`) that directly
isolates a bound `MemberExpr` and passes it to `EvaluateAsRValue()`,
asserting it returns `false` without crashing.
* Added clangd hover test
(Hover.NoCrashOnBoundMemberFunctionWithNewInterpreter)
that reproduces the original crash scenario.
* *Note:* I could not add a Lit test because I believe this is
unreachable via normal `clang` invocations. `Sema` strictly catches
isolated bound member functions before constant evaluation. `clangd` has
a unique path to triggering this.
**Root cause:**
This is exposed by C++23 specifically due to (I think P2280R4 /
P2448R2):
- Relaxing the rules around "unknown" objects in constant evaluation,
allowing `s` in `s.f()` to proceed past the base object check even
though `s` is not constexpr and deferring failures to bytecode execution
rather than rejecting them structurally.

[clang][CIR] Add lowering for fp16 intrinsics (#194865)
This PR adds lowering for the following intrinsic groups:
* https://arm-software.github.io/acle/neon_intrinsics/advsimd.html#absolute-difference-1
* https://arm-software.github.io/acle/neon_intrinsics/advsimd.html#reciprocal-estimate-1
* https://arm-software.github.io/acle/neon_intrinsics/advsimd.html#reciprocal-estimate-1
It also moves the corresponding tests from:
* clang/test/CodeGen/AArch64/v8.2a-fp16-intrinsics.c
to:
* clang/test/CodeGen/AArch64/neon/fullfp16.c
The lowering follows the existing implementation in
CodeGen/TargetBuiltins/ARM.cpp.

[analyzer][NFC] Rename class `StackFrameContext` to `StackFrame` (#195802)
This patch continues the refactoring roadmap described in issue #190973
by renaming the `StackFrameContext` class to just `StackFrame`. Many
variables of type `const StackFrame *` also had their names updated to
reflect the new class name `StackFrame`.

[NFC][analyzer] Introduce specialized variants of makeNode (#194459)
This commit introduces new methods `makePostStmtNode` and
`makeNodeWithBinding` of `CoreEngine`, which will be used instead of the
5-parameter overloads of `NodeBuilder::generateNode` and
`NodeBuilder::generateSink` (which were originally methods of the class
`StmtNodeBuilder` that was deleted in commit
fb46677a858697afa116c4252e84050a07bc6a70).
This commit applies the newly introduced methods in a few places (as
examples), but there are 80+ call sites that use the 5-parameter
`NodeBuilder::generateNode` or `generateSink`, so this transition will
be completed in multiple follow-up commits.
I decided to introduce these methods because after the transition there
will be 20+ calls to `makePostStmtNode` and 30+ calls to
`makeNodeWithBinding` and it would be cumbersome to use plain `makeNode`
instead of these specialized variants.
(On the other hand these new methods don't support specifying a `tag`
because only a few call sites would use that feature of the 5-parameter
`generateNode`.)

[ADT] Bitset: add shift operators, word accessors, and etc (#193400)
This PR is split out from #191757 per reviewer request. It has the
following changes to `llvm::Bitset<N>`:
* Added `operator<<`/`<<=`/`>>`/`>>=`, `getNumWords()`, `getWord()`, and
`findLastSet()`.
* Moved the `std::array<>` constructor from protected to **public** and
**explicit**.
A follow-up PR will use these to re-implement `LaneBitmask` as a
`llvm::Bitset` wrapper.
---
The unit test in the PR is largely generated by LLMs. I have reviewed it
and manually applied changes to cover more edge cases.

[mlir][emitc] Refactor the e2e test for TOSA -> EmitC lowering (#194686)
Update the TOSA -> EmitC test, mlir/test/Dialect/EmitC/tosa/ops.mlir, to also
compile the generated source with a C++ compiler. This adds an `mlir-translate`
step, making the overall flow:
mlir-opt tosa.mlir | mlir-translate | c++ -Wall -Werror -c
Although the test still does not execute the generated code, compiling it with
a host compiler increases coverage and makes the test closer to an integration
test. For this reason, move it to:
mlir/test/Integration/Dialect/EmitC/
The source generated by the translator uses `size_t`, which requires the
`stddef.h` header. This is currently provided explicitly in the compile step
with `-include stddef.h`; a follow-up should consider emitting the required
include from the translator instead.

[lldb] Flush delayed breakpoints before eagerly changing one (#195815)
See the discussion in https://github.com/llvm/llvm-project/pull/192971
When LLDB makes the decision to eagerly send a breakpoint packet, it
should first ensure the delayed breakpoints are flushed, as they may
interfere with the eager breakpoint that is about to be changed.
Implementation note: we could have included the eager breakpoint in the
batch that is about to be flushed. However, it's important to get
information about the error status of this eager breakpoint, and the
current APIs dont make it easy to distinguish which breakpoint caused an
error.

[libc] Add socket test support library (#193207)
A couple of tests (and I plan to add a couple more) need to
create/compare unix domain socket addresses. This isn't completely
trivial due to the the interaction between the `addrlen` argument and
the terminating '\0', and the existing code doing that was subtly wrong
in some cases.
This patch centralizes the functions for these operations, reducing code
duplication and ensuring consistent (and correct) behavior everywhere.

Log Message:
-----------
[clang][test] Add missing `FileCheck` in Import/destructor/test.cpp (#195778)
The test had `CHECK` directives that were never executed because the
`RUN` line did not pipe output to `FileCheck`. This also replaces
`CHECK-NEXT` with `CHECK-SAME` so the subsequent `CHECK-SAME` directives
match the remaining destructor properties in order.

[SystemZ] Replace PatLeaf with ImmLeaf (#195146)
The code snippets for the predicates are a bit shorter, because the
APInt is directly available instead of an SDNode. Main advantage is that
it enables the constraint to be ported to GlobalISel.

[EarlyCSE] Check if getValueType() returns nullptr (#195868)
15383dcdb4012387d94fab67fed4519613bf9a19 recently added a call to
getValueType() into EarlyCSE without checking whether or not it returned
nullptr. It sometimes might end up processing target specific intrinsics
for which the underlying getAccessType will typically return nullptr.
We observed this crash when building https://github.com/google/highway
for AArch64.
Regression test added to ensure this does not occur again in the future.

PeepholeOpt: Clear kill flags in foldImmediate (#195680)
When foldImmediate replaces a COPY destination with its source,
this extends the live range of the source, but it does not update the
kill flags.
Clear kill flags on the source register after replacement.
This was found while working on REG_SEQUENCE optimizations motivated by
AMDGPU demands. Both an AMDGPU and an X86 test case are added to show that
the issue is not AMDGPU specific.

Log Message:
-----------
[lldb][windows] fix cross DLL file descriptor lookup crash (#195855)
On Windows, file descriptors are only valid in the same DLL: they are
really just handles mapped to an index in a table in the CRT. Calling a
liblldb method with a file descriptor from lldb-dap will cause the
program to crash. See
https://github.com/llvm/llvm-project/issues/193971.
This patch fixes the issue by refactoring the `NativeFile` constructors
so that they no longer try to convert `FILE` types to handles through
the CRT lookup table.
