[lldb][Windows] Mark test as expected failure (#207153)
In f31853255c300e07b93783425e40948cc0dfdb0f, this test was marked as
expected failure only when running with `lldb-server.exe`. It shoulds
not have been, it is still failing. Revert the decorator to
`expectedFailureWindows`.

[LLVM][CodeGen][SVE] Add ElementSize information to pseudo instructions. (#206133)
https://github.com/llvm/llvm-project/pull/204820 is making more use of
an SVE instruction's element size. To make best use of this the pseudo
instructions need to carry the same information because the pass is run
before expansion. This PR adds the necessary data and updates
AArch64SVESchedPseudoTest to verify the data matches the real
instruction it represents.

[Dexter] Allow matching lists of values for aggregate members (#204160)
This patch slightly extends the matching of aggregate members to allow
for lists of expected values for individual functioning the same as
lists of expected values for scalar values. This is accomplished by
recursively calling `get_expect_match` instead of `DebuggerExpectMatch`,
which contains logic for matching against all possible expected values
and selecting the best match (and committing any associated context
changes, e.g. modified address labels).

[offload] check olInit and olShutDown error in unittests initialisation (#206764)
if olInit fails, it leaves liboffload in an inconsistent state (proper
cleanup will be addressed in a follow-up patch). This can lead to
seemingly unrelated test failures (e.g. the host device is missing).
This patch makes such tests fail immediately with a clear error message.

the COFFObjectFile earlier and use it for both the findBitcodeInObject
call and ObjFile creation. It's also preparation for handling hybrid
ARM64X object files.

real-world input. Rename the user-facing flag to unsupported-z3 and
reword its description so users see up front that the backend is
unsupported and crash-prone -- patches welcome, crash reports are not.

[SCCP] Avoid markConstant() in more places (#206494)
This extends the fix from 991455e69e93c0ce88e927eddd28a9ab34d1f8b2 to
two more places. In both of these, we can run into the same situation
where we first mark as constant with a vector that has poison values,
and then again without poison elements, resulting in an assertion
failure.
(An alternative would be to change markConstant() to allow calls with
different constant if the new constant is a vector that only refines
some previously poison elements?)

Adds a new node type, !float, which can be used to match debugger ouptut
as
float values rather than as strings, optionally allowing a range to be
specified for inexact matches. This new node allows a list of values to
be
given, effectively a shorthand for a list of individual !float nodes.

OpenACC requires we check that a variable have the same operator in all

This patch adds checks for that as well as 'this' so we should correctly
get the checks.

[X86] Add AVX512BMM support for AMD Zen 6 (znver6) (#182556)
This patch adds support for AVX512BMM (Bit Matrix Multiply) instruction
set extension for AMD Zen 6 processors.
AVX512BMM includes three instructions:
- VBITREVB: Bit reverse within each byte
- VBMACOR: Bit matrix multiply with OR accumulation
- VBMACXOR: Bit matrix multiply with XOR accumulation
The following implementations for AVX512BMM are added:
- Define __AVX512BMM__ macro for znver6
- avx512bmmintrin.h, avx512bmmvlintrin.h header files
- Implement _mm_bitrev_epi8, _mm256_bitrev_epi8, _mm512_bitrev_epi8
- Implement _mm256/512_bmacor16x16x16 and bmacxor intrinsics

condition inside a loop.
Previously when a loop contained a condition, this would introduce a
BLEND to the chain, which prevented a partial reduction from being used
in a pattern where it would normally be created.
This patch records the blend as part of the partial reduction chain and
recognizes blends that select between the updated reduction value and
the previous accumulator.
For tail-folded loops, the transform also combines the loop active-lane
mask with the blend condition, so the generated partial reduction is
predicated by both the tail-folding mask and the original loop
condition. This allows partial reductions to also be used for predicated
reductions with tail folding enabled.

[Clang][CodeGen] Emit alignment information for indirect arguments (#201999)
Previously, arguments with `ABIArgInfo::Indirect` would not be given
alignment information if it wasn't `byval`. This could prevent certain
optimizations, such as those guarded by
`isDereferenceableAndAlignedPointer` checks. The missing
dereferenceability information is pointed out in
https://github.com/llvm/llvm-project/issues/129337, for example.
This PR will fix the first half of this problem, which is emitting
alignment information. Dereferenceability information will be added in a
subsequent PR.

[sanitizer] Raise kMaxAllowedMallocSize to 1TB on AArch64 (#206649)
lsan capped AArch64 allocations at 4GB and msan at 8GB. These limits
were tied to the smaller address space of the 32-bit-style allocator.
This became possible after 8e0c1aaf6ba3 ("[msan] Use
SizeClassAllocator64 for AArch64"), which (together with the 48-bit VMA
requirement) switched AArch64 to SizeClassAllocator64, so the limit can
now match the other 64-bit targets (1ULL << 40).

[flang][OpenMP] Fix user-defined reduction shadowing an intrinsic name (#205893)
A user-defined reduction whose identifier is one of the intrinsic
reduction names (max, min, iand, ior, ieor) was mishandled during
lowering, causing a crash. This was due to two different problems:
1. Intrinsic shadowing: a reduction(max:var) clause resolves its
identifier to the intrinsic procedure rather than to the user's
declaration, so lowering applied the built-in reduction and ignored the
declared one. For integer variables this silently used the wrong
combiner/initializer; for a LOGICAL variable it crashed, because the
built-in MAX/MIN initializer calls getIntOrFloatBitWidth() on a
fir.logical type.
Per OpenMP 6.0 7.6.14, a user-defined reduction has the same visibility
and accessibility as a variable declared at the same location, so a
visible declaration must take precedence over a same-named intrinsic.
This is handled the same way as for user-defined operator reductions.
TODO: imported, renamed, or multiple-declaration/type reductions are
currently not implemented.
2. LOGICAL initializer type: a user-defined reduction on a LOGICAL
variable with a logical-literal initializer (e.g. omp_priv = .false.)
lowered the literal to an i1 and yielded it from the init region, but
the reduction type is !fir.logical<4>. The omp.declare_reduction
verifier then rejected the op ("expects initializer region to yield a
value of the reduction type"). Convert the initializer result to the
reduction type when they are convertible trivial types, so the init
region yields the reduction type.

[Dexter] Add additional variable metrics, sanitize lldb-dap function names (#204366)
This patch makes some required changes prior to switching over to using
the script model by default, to keep the tests in `dexter-tests` working
and meaningful.
In addition to the existing metrics, we split the "missing_vars" metric
into 3 - adding "irretrievable" and "optimized_out", so that we can
specifically test those properties in the output.
We also add some function name sanitizing to lldb-dap, to account for
the fact that some function names get presented with a suffix " [opt]",
which causes the script to fail.

[lldb][test] Skip tests for features unsupported on WebAssembly (#207102)
- TestReturnValue, TestTrivialABI: a WebAssembly return value lives on
the operand stack with no way to locate it at a step-out, so the
returned value can't be recovered.
- TestScriptedFrameProvider, TestFrameProviderThreadFilter: the inferior
is multithreaded C++, which wasip1 can't build (no threads, and
inferiors are compiled without exception support).
- TestThreadLocal: reading thread-locals works, but the test checks the
platform-specific error reported when TLS isn't initialized yet, which
WebAssembly doesn't have (already xfail/skip on other platforms).

[lldb] Synthesize data symbols for WebAssembly from DWARF (#207235)
The Wasm "name" section names functions but not data, so data symbols
such as C++ vtables have no entry in the symbol table. The Itanium C++
runtime resolves a dynamic type by looking up the symbol at an object's
vtable pointer and reading its "vtable for X" name. With no such symbol,
dynamic type resolution fails and falls back to the static type.
The vtable's address and mangled name are available in the DWARF as a
DW_TAG_variable with a DW_OP_addr location and a DW_AT_linkage_name.
Extend SymbolFileWasm::AddSymbols to synthesize a data symbol for every
global variable of that shape, so its address resolves back to the
mangled name such as "vtable for X". The size is computed by Symtab to
from the gap to the next symbol.

[Dexter] Update lldb-based dexter-tests to use script-mode (#204367)
This patch replaces uses of heuristic-mode Dexter in the dexter-tests
suite with uses of the script-mode, for tests that use DAP (via
lldb-dap). The updates are largely straightforward but occasionally
non-trivial, and in some cases some slight modifications have been made
to keep the "spirit" of the test intact.

[lldb][CMake] Extend liblldb interposition fix to lldb-dap and lldb-mcp (#207251)
liblldb statically absorbs the lldbHost and lldbUtility archives (and
every plugin). A tool that links the shared liblldb while also linking
those same archives statically ends up with two copies of that object
code. On ELF, if the tool re-exports the archive symbols in its own
.dynsym, the dynamic linker can bind liblldb's internal references to
the tool's copy instead of liblldb's own, breaking shared-state
assumptions such as the HostInfo singletons.
106644f6c835 fixed this for the lldb driver with --exclude-libs,ALL, but
lldb-dap and lldb-mcp have the same setup and were left exposed. Factor
the logic into a shared lldb_prevent_liblldb_symbol_interposition helper
and call it from all three tools.

[DirectX] Remove now unreachable blocks in dxil legalize (#207259)
I think when I first wrote
https://github.com/llvm/llvm-project/pull/193592, I had been under the
assumption that the dead block would be removed for us so the test and
pass did not check that the branch was removed in the pass.
This was a wrong assumption and we need to manually remove the blocks.
This change does so by invoking the helper to do so.
For context: this issue reappeared in the offload test suite after
https://github.com/llvm/llvm-project/pull/205433 landed because the loop
could no longer unroll and the dangling branch appeared.

This PR adds a test for

[[cpp.replace.general] paragraph

> A translation unit shall not `#define` or `#undef` macro names
lexically identical to keywords, to the identifiers listed in Table

> [Note [1](https://eel.is/c++draft/cpp.replace.general#note-1): An

Therefore it is not possible to define a macro whose name is the same as

Since C++98 and up until

"Preprocessing is never undefined", which was voted into C++26 **not**
as a DR, this rule has been living as [macro.names]/2 in library
introduction, but that paper made it a part of the core language.
I believe that formally:
- we should not diagnose anything before C++26 if the standard library
is not used, and
- we should diagnose everything in C++26 and newer modes.
But in practice we've been diagnosing everything except for attributes
in all language modes with some exceptions that are likely bugs.

Add a pre-filter to the breakpoint resolver overrides (#198845)
That way if an override only wants to override, say, file and line

the work of creating the resolver and checking with it if the breakpoint
wasn't of the requested type.

[VPlan] Strip early-bail in noalias-check (#203936)
canHoistOrSinkWithNoAliasCheck currently bails eagerly when the
candidate memory location doesn't have a scope. This is unnecessary,
because the alias check automatically handles this: stripping this check
allows us to run the loop, which would never get to the alias check if
none of the recipes write to memory. The end result is that a read-only
FirstBB to LastBB ranges are determined not to alias with anything, even
if the scope metadata is absent, leading to licm-load-store
improvements.

[Clang] Fix offsetof sign-extending unsigned array indices >= 128 (#204139)
When evaluating __builtin_offsetof with an unsigned integer array index
(e.g. uint8_t, uint16_t) whose value has the high bit set, Clang was
calling getSExtValue() on the APSInt index, which sign-extends the value
and produces a large bogus offset.
Fix this to use the correct kind of extension to extend smaller values, and to check for overflow in conversions of larger values.
Fixes #199319
AI Tool Use: GitHub Copilot (Claude Sonnet 4.6) was used to assist in
identifying the root cause of the bug in ExprConstant.cpp and drafting
the fix. The fix was reviewed, tested, and validated manually.

Log Message:
-----------
[AArch64] Lower cttz(bitcast <Nxi1> to iN) with shrn-based compressed movemask (#199081)
The existing lowering in vectorToScalarBitmask() creates a 1 bit per
lane movemask using a powers of 2 reduction (and+addv with a constant
pool entry).
This patch adds a DAG combine on ISD::CTTZ that recognizes cttz(bitcast
<N x i1> to iN) and produces a compressed movemask with shrn (for i8
lanes) or xtn (for wider lanes) then runs scalar cttz on a 64- or
128-bit value. Dividing by bits per lane gives the lane index.
Supports lane counts {2, 4, 8, 16, 32} (one or two NEON registers)
For the example in the issue (`<16 x i8> -> i16`):
Before:
```asm
adrp x8, .LCPI0_0
cmlt v0.16b, v0.16b, #0
ldr q1, [x8, :lo12:.LCPI0_0]
and v0.16b, v0.16b, v1.16b
ext v1.16b, v0.16b, v0.16b, #8
zip1 v0.16b, v0.16b, v1.16b
addv h0, v0.8h
fmov w8, s0
orr w8, w8, #0x10000
rbit w8, w8
clz w0, w8
ret
```
After:
```asm
cmlt v0.16b, v0.16b, #0
shrn v0.8b, v0.8h, #4
fmov x8, d0
rbit x8, x8
clz x8, x8
lsr x0, x8, #2
ret
```
Also created a new test file with 24 functions covering both endianness
- 7 basic widths (`<16 x i8>` down through `<2 x i32>`)
- 4 wider cases that span two NEON registers (`<32 x i8>` etc)
- 2 narrow cases that get sext'd up to fit one register
- 2 cases where the bitcast has two users
- 4 alternative comparison operators (`eq`, `ne`, etc)
- 1 `cttz` with `is_zero_undef=true`
- 4 negative tests that bails for unsupported shapes

[LegalizeType] Fix VECTOR_DEINTERLEAVE widening with incorrect insert_subvector (#207245)
Partially address #207136
There are really two parts in the associated issue: (1) incorrect type
widening logics that `insert_subvector` with indices that are not a
multiple of the sub-vector's minimum number of elements, and (2)
incorrect RISC-V lowering logics when it comes to fixed vector.
This PR addresses the first part: It turns out in order to have a
widened, packed concat vector, we don't need to use any insert_subvector
that involves widened operands -- just `concat_vectors` on the
_original_ (narrow) operands (before adjusting to the size of the
desired widened concat vector)

lit: improve long path support on Windows (#207250)
This pull request improves Windows path handling in the
`llvm/utils/lit/lit` utilities by introducing and applying an `extended`
function to correctly format file paths for Windows APIs, especially for
long paths and UNC paths. The changes ensure that file operations such
as removal and redirection work reliably on Windows systems.
**Windows path handling improvements:**
* Added an `extended` function in both `InprocBuiltins.py` and
`ShellEnvironment.py` to convert paths to the extended-length format
required by Windows, handling both regular and UNC paths.

* Applied the `extended` function to file removal operations in
`InprocBuiltins.py`, ensuring paths are properly formatted before
deletion, which helps avoid issues with long or special Windows paths.
* Used the `extended` function for redirected file paths in
`ShellEnvironment.py`, ensuring that redirections to files handle
Windows path limitations correctly.

[clang][ssaf] Add `MultiArchSharedLibrary` data structure (#206854)
This change introduces `MultiArchSharedLibrary` data structure that wraps per-architecture `LUSummaryEncoding` members. This is the SSAF analogue of a fat shared library. The overall design mirrors the existing `MultiArchStaticLibrary` design: each member identifies the same logical library built for a different target triple. Support for constructing and consuming this object will be added in a future PR.

[DAGCombiner] Reassociate chains of vector reductions (#206471)
`DAGCombiner::reassociateReduction` already folds a single
`add(vecreduce(x), vecreduce(y)) -> vecreduce(add(x, y))`, and the
balanced-tree form `add(add(vecreduce(a), b), add(vecreduce(c), d))`.
It does not, however, handle a linear chain of reductions like the one
SLP emits for x264's SAD:
```
add(reduce(X0), add(reduce(X1), add(reduce(X2), acc)))
```
Only the innermost pair can ever be merged; the cascade breaks and every
reduction survives to lowering, giving one `vredsum` (or one `uadalp` step,
etc.) per term.
This PR adds a third form to `reassociateReduction`:
```
op(vecreduce(X), op(vecreduce(Y), Z)) -> op(vecreduce(op(X, Y)), Z)
```
Applied to fixpoint by the combiner worklist, this collapses an
arbitrary-length chain into `add(vecreduce(BigSum), acc)`, which the
existing target combines then fold into a single reduction with the
external accumulator folded in as the reduction start value. On RISC-V
with `Zvdot4a8i` this recovers the desired single-`vredsum`, N-dot codegen
for x264 SAD; it also shortens the critical path for other targets (e.g.
AArch64 `uadalp`/`faddp` reduction chains) by exposing a balanced tree.
It is gated on the existing `shouldReassociateReduction` target hook and,
for `FADD`/`FMUL`, only enabled when all involved nodes carry the `reassoc`
fast-math flag, matching the existing two forms.
Fixes #168047.

[CodeGen] Merge TargetRegClass into MCRegClass (#207168)
Both data types store primitive information only and TargetRegisterClass
doesn't reference target-specific data structures. TargetRegisterClass,
however, freqeuently refers to MCRegisterClass through a pointer, which
prevents moving the large TargetRegisterClass instances to .rodata.
Therefore, merge the fields of TargetRegisterClass into MCRegisterClass
and adjust the remaining fields to use the existing storage mechanism
for pointer-free storage. To avoid invasive code changes, keep
TargetRegisterClass as alias for MCRegisterClass.
This reduces the size of .data.rel.ro by ~122 kiB in an all-target
build while growing .rodata by just 92 kiB. Further size improvements
are possible in future by reordering struct fields and deduplicating
masks/register lists/register class lists.

[IR] Enable dereferenceable-at-point semantics (#204795)
The precise semantics of `dereferenceable` are currently undocumented,
but de facto they are:
* Argument position `dereferenceable` implies that the memory remains
dereferenceable while the function executes.
* Return position `dereferenceable` implies that the memory remains
dereferenceable forever.
This is not coherent with how these attributes are used, in at least two
ways:
* C++ reference arguments are annotated as `dereferenceable` by Clang.
However, C++ does not actually make any guarantees that the underlying
memory does not get freed during the execution of the function. (Unlike
Rust, which does guarantee this via protectors in SB/TB.)
* We infer `dereferenceable` on allocator return values (from
`allocsize`). Allocator return values quite obviously do not stay
dereferenceable forever, as they can be freed.
This PR changes the semantics of `dereferenceable` to apply at-point,
i.e. only directly on function entry (for arguments), or at the position
of the call (for return values). The fact that the memory cannot be
freed between the point where the `dereferenceable` fact has been
established and the point where we're trying to speculate needs to be
explicitly proven now.
The main ways this happens is:
* Via `nofree` function attributes (inferred).
* Via `noalias nofree` argument attributes. The latter is inferred, but
the former generally requires frontend annotation. In Rust the
combination of `noalias nofree dereferenceable` is used, so it should
not be materially affected by these changes.
* Context-sensitive analysis to check for frees (i.e. non-nofree calls
or synchronizing atomics) between the point of definition and the point
of speculation.
It's expected that this will regress optimization of C++ code in some
cases, because we can no longer use dereferenceability facts that are
not, in fact, guaranteed to hold.
This finishes implementing an old RFC:

[X86] matchUnaryShuffle - only prefer VZEXT_MOVL to VPMOVZX if it will fold away (#207031)
Clean up the logic matching VZEXT_MOVL in preference over VPMOVZX - we
should only use this if the source vector is GPR->FPU or a single
element load (or target load), which fold away to an implicit zero
extension.
Pre-SSE41 targets will attempt to match VZEXT_MOVL again more generally
later on.

[VPlan] Intersect all fast-math flags in VPIRFlags::intersectFlags (#204664)
intersectFlags only ANDed the nnan and ninf flags and left the others
reassoc, arcp, contract, afn and nsz) unchanged. When CSE or
interleave-group narrowing combines two operations into one, the kept
operation's remaining flags then leak onto the merged value.
Intersect all fast-math flags instead, so the result keeps only the
flags present on both operations. A pure intersection is required
because the combined operations do not always compute the same value
(e.g. when narrowing interleave groups), so a flag may be kept only if
every combined operation had it.

[AMDGPU] IGroupLP: Avoid DAG manipulation in greedyFind (#194827)
The greedy pipeline solver needs to determine the edges that are
implied by assigning an SUnit to a SchedGroup and the cost of this
assignment. The cost is the number of edges that cannot be added without
introducing cycles. The current implementation (addEdges) adds the
edges to the DAG and uses the DAG reachability function for cycle
checking. This happens for each candidate SchedGroup and needs to be
undone before other candidates are considered. The DAG manipulations
become a significant performance bottleneck on bigger pipelines.
This commit implements an alternative function for computing the edges
and cost of an assignment. This function performs the reachability
analysis that is necessary for the cyclicity checks without modifying
the DAG.
The new function returns the same cost as addEdges. The concrete edge
set may show insignificant differences, because, for instance,
the link function called from addEdges chooses not to add transitive
edges (DAG manipulations are more expensive than the check to avoid
this), but the new function includes such edges since this means that
it can avoid to update reachability information in one direction.
The schedule changes are caused due to the existing implementation not
resetting the DAG's topological order after removing the edges that
are added while examining the SchedGroup candidates. Hence it may have
used incorrect reachability information.

[clang] use decl itself in static assert failed boolean condition printer (#203736)
fixes #203701
`getName()` assumes the decl used in the static asserts has a simple
identifier name, but in some cases like `operator int` don't — they
fails the assertion `Name.isIdentifier() && "Name is not a simple
identifier"` when the `static_assert` failure diagnostic tries to print
the boolean expression.
Switching to getDeclName() handles these special names properly.
Reproducer:
```c++
struct S {
constexpr S(auto) {}
constexpr operator int() const { return 0; }
};
constexpr auto a = [](this S) { return 1; };
static_assert((&decltype(a)::operator())(1) == 42);
```
---
One thing I'm not sure about: the print helper that walks the boolean
expression lives in `SemaTemplate.cpp` (inside
`printTemplateArgumentList` / the DiagRecursiveConstraintEval visitor
area). Is there a historical reason for it being there rather than
somewhere more general like `SemaOverload.cpp` or a shared diagnostic
utility? Happy to move it if that makes more sense.

[CrossProjectTests] Fixup expect in ctor.cpp to accept multiple steps (#207337)
In the test `ctor.cpp`, Dexter tests that when we step into the
constructor used in the test, the value of `this` isn't irretrievable.
To protect against a rotten pass it also checked that we stepped once,
but this caused failures on some platforms where we would step twice on
the constructor - this patch resolves the issue by accepting any
non-zero value for the number of steps.

[IR] Explicitly specify target feature for module asm (#204548)
Support specifying additional properties on module-level inline
assembly. In particular, the target features and target CPU can now be
specified as follows:
module asm(target_features: "+foo", target_cpu: "bar")
"asm line 1"
"asm line 2"
There may be multiple module inline assembly blocks with different
properties.
This is intended to fix the long standing issue where in LTO scenarios
we don't know what target features to use for parsing the module-level
inline assembly. Now they can be faithfully preserved, even when merging
inline assembly from different modules with different features.
If target_features and target_cpu are empty, we fall back to the old
behavior (which, in the backend, would be to use the default subtarget
of the TargetMachine).

[libc][ARM] Defend banked SP setup against register allocator (#206757)
The startup code for bare-metal AArch32 A/R shifts the CPU through all
the different modes which have their own copies of SP, updating all the
stack pointers to the same value. But it does it using C intrinsics,
leaving the register allocation to the compiler – so it's possible that
the register allocator happens to use one of the _other_ banked
registers, such as LR.
For example, when I built this code today, it happened that LR was used
to hold one of the constants written into CPSR_c to change mode. That
constant was written into the SVC mode LR before any mode changes, but
the MSR instruction that tried to use it was run in a different mode, so
it copied from _that_ mode's LR, which contained uninitialised nonsense
in place of the desired constant, triggering a boot-time crash.
I think it's safer to use a single asm statement for the whole job,
guaranteeing which registers it uses.

[Dexter] Switch to using script-mode by default (#204369)
This patch changes the default mode of Dexter from heuristic-mode to
script-mode. The --use-script argument is replaced with --use-heuristic,
some comments/docs/error messages are updated accordingly, and tests
have their flags switched accordingly.

[AArch64] Fix reversed values in big-endian 128-bit atomics (#205760)
When AArch64TargetLowering expands a load-linked or a store-conditional
during the atomic-expand pass, it made the fixed assumption that the
64-bit value stored first in memory was the low-order half of the
128-bit value, instead of checking the SubtargetInfo's endianness. The
same was true of the code that expands CMP_SWAP_128 pseudoinstructions.
So in each case, if you compiled 128-bit atomic code big-endian, you'd
get back a 128-bit integer with the top and bottom half swapped.
This was found by compiler-rt's existing tests when we ran them for a
big-endian AArch64 target in Arm Toolchain.
Most of the test changes here are `update_llc_test_checks` churn: there
were already many tests of AArch64 atomics in big-endian mode, and
apparently they all simply had the reversed registers in their expected
output.
The one new test, `aarch64_i128_endianness.ll`, directly demonstrates
the failure if run against llc without the patch, because it does both
atomic and normal loads and stores in each test function, and you can
see in the big-endian generated code that the same pair of registers is
used in opposite orders by the ldxp/stxp and ldp/stp instructions. After
this fix, the order of the registers matches.

[CI][flang][OpenMP] Build OpenMP runtime mod files for flang tests (#206517)
Some flang openmp lit tests require mod files (a bit like C header
files, except they are compiler generated) from the openmp runtime. As
the openmp runtime is not currently built in this configuration, these
71 flang tests get skipped and a warning is emitted.
Here I enable openmp as a dependency for flang but add
-DLIBOMP_FORTRAN_MODULES_ONLY=ON so that only the required mod files are
built and not the whole of the openmp runtime.
This only effects linux bots: Windows and MacOS explicitly exclude
openmp so it will still not be enabled there.

[mlir][linalg/scf/transform] scalable tiling and fusion for pack/unpack ops (#204007)
# Inner tile alignment hints for scalable `linalg.pack`/`linalg.unpack`
tiling and fusion
## Overview
Tiling and fusing `linalg.pack`/`linalg.unpack` produces a clean result
only when the tiling implementation can tell how a loop tile size
relates to the op's inner tile size. When both are statically known this
is decided by comparing the constants. But with **scalable** (and, more
generally, dynamic) sizes, e.g. a loop tile of `8 * vscale` against an
inner tile of `8 * vscale`, that relationship is symbolic and cannot
cleanly be recovered from the IR, so the implementation conservatively
falls back to a dynamic, over-allocated tile. See #150185 for more
details.
This PR adds an optional **inner tile alignment hint**: a per-dimension
caller assertion about that relationship, threaded from the transform-op
surface through the SCF driver into the pack/unpack `TilingInterface`
implementations. The caller is already aware of both the loop tile
sizes, and the inner tile sizes, and therefore can set these hints
easily. With the hint, scalable pack/unpack tiling and fusion produce
the same tight IR they produce for the statically-aligned case.
## The inner tile alignment hint
`InnerTileAlignment` is a per-iteration-domain-dimension enum:
- `Unknown` (`0`) — no information; the implementation keeps its prior
behavior.
- `Multiple` (`1`) — the loop tile size is an integer multiple of the
inner tile.
- `Equal` (`2`) — the loop tile size equals the inner tile size.
It is a *caller assertion*, not a checked fact. It is consulted only
when the relationship cannot be decided from the IR; when the tile and
inner-tile sizes are both statically known, that static comparison wins
and a contradicting hint is ignored rather than allowed to corrupt the
result. Otherwise the hint is not verified, so an incorrect assertion
silently produces invalid tiling, its correctness is owned by the
caller. Only pack/unpack consult it; every other op ignores it.
## TilingInterface API
Four methods gain a second overload taking an extra
`ArrayRef<InnerTileAlignment>` hint:
- `getTiledImplementation`
- `generateResultTileValue`
- `getTiledImplementationFromOperandTiles`
- `getIterationDomainTileFromOperandTiles`
The hint-bearing overload defaults to forwarding to the hint-less one,
so the change is additive: existing implementers and callers that never
mention the hint are unaffected, and the rest of the interface is
untouched.
### Where it helps
The loop tiles the packed dimension by `8 * vscale`, so the size handed
to the pack/unpack is a **full-or-remainder** `affine.min` against that
step:
```mlir
// #map = affine_map<(d0)[s0] -> (-d0 + 4096, s0)> // min(4096 - iv, 8*vscale)
%ts = affine.min #map(%iv)[%c8_vscale]
// ... %ts feeds the extracted slice fed to the pack/unpack, whose inner tile
// on this dimension is also 8*vscale.
```
To fold the tiled op's outer (tile-count) dimension to a static `1`, the
current implementation asks
`ValueBoundsConstraintSet::computeConstantBound` for a *constant* upper
bound on `%ts` and compares it against the inner tile size, essentially
`UB(%ts) % innerTile == 0`. With a scalable `8 * vscale` inner tile,
neither the upper bound of `%ts` nor the inner tile is a constant, so
the comparison is undecidable and the tile conservatively falls back to
a dynamic outer dim (`tensor<?x...>`), over-allocating the tile.
`inner_tile_alignments = [Equal]` asserts `%ts == 8 * vscale`, so the
outer dim folds to a static `1` (`tensor<1x...>`); `[Multiple]` instead
takes the `ceilDiv` branch. The hint thus supplies exactly the
relationship the upper-bound comparison cannot recover for symbolic
sizes.
### How the hint is arranged
- One entry per **iteration-domain dimension**, in **pre-interchange**
order (`interchange` only reorders the generated loops, not the hint).
- Entries are **not** remapped through indexing maps or
`outer_dims_perm`: for a transposing pack they stay in source
(pre-permutation) order.
- For the consumer-fusion (`*FromOperandTiles`) methods, the indexing
follows the op's iteration domain: for a pack it coincides with the
unpacked source dims; for an unpack the entry for the i-th inner tile
sits at its destination dimension `inner_dims_pos[i]`.
The caller must pre-arrange the array to match this order. See the tests
for more examples.
### Out-of-tree implementers
Because the two overloads share a source name:
- An op that lists one of the four methods in
`DeclareOpInterfaceMethods` now has **both** arities declared on it, so
it must also define the hint-bearing overload (typically a one-line
forward to the hint-less one).
- An `ExternalModel` that defines the hint-less overload **hides** the
inherited defaulted hint-bearing overload (C++ name hiding); add `using
Base::<method>;` to keep it visible.
Implementers that do not care about the hint need no functional change
beyond the above visibility boilerplate.
## SCF tiling driver API
The producer- and consumer-fusion driver entry points
(`tileAndFuseProducerOfSlice`, `tileAndFuseConsumerOfSlices`,
`tileAndFuseConsumer`) and `SCFTilingOptions` accept an optional
**control function** rather than a single fixed array.
A single tile-and-fuse invocation can tile/fuse several ops with
**different iteration domains**, so no single array can be correct for
all of them. The driver therefore invokes the control function once per
op being tiled/fused and
expects the returned array to be in *that op's own* domain, it does not
remap it.
### Why a control function and not one array
A single tile-and-fuse can pull in more than one pack/unpack, and each
consults the hint in *its own* iteration domain:
```mlir
%unpacked = linalg.unpack %p0 inner_dims_pos = [0] inner_tiles = [%c8_vscale] ... // domain A
%mul = linalg.generic ins(%unpacked, ...) ... // tiled root
%packed = linalg.pack %mul inner_dims_pos = [1] inner_tiles = [%c4_vscale] ... // domain B
// One tile-and-fuse: tile %mul, fuse %unpacked (producer) and %packed (consumer).
```
Both `%unpacked` and `%packed` consume the hint, but their domains
differ, a different dimension is tiled and the inner-tile arrangement is
different, so the array indexed in `%unpacked`'s domain is simply wrong
for `%packed`. No single fixed array can be correct for both. The driver
therefore invokes the control function once per op being tiled/fused and
the caller returns each op's array in its own domain.
### Why the function gets slices (not tile sizes) for fusion
For pure tiling the driver knows the explicit tile sizes and passes
them. In fusion there are no caller-specified tile sizes for the fused
op, its tile is induced by the `tensor.extract_slice` (producer) or
`insert_slice` (consumer) being fused. The control function is therefore
handed those slices, from which the caller can derive the alignment in
the fused op's domain.
## Transform ops
`transform.structured.tile_using_for`, `transform.structured.fuse`, and
`transform.structured.fuse_into_containing_op` gain an optional
`inner_tile_alignments` array attribute (empty by default, preserving
prior behavior). It is wired to the driver as a **constant** control
function (the same array for every op). This is sufficient because each
of these ops drives tiling/fusion at single-op granularity; the per-op
control function remains available at the library/driver level for
callers that fuse multiple ops with differing domains. The test-only
`transform.test.fuse_consumer` is wired the same way.
## Testing
- **`linalg.unpack`**: standalone tiling, producer fusion
(`structured.fuse`, `fuse_into_containing_op`), and consumer fusion
(`test.fuse_consumer`), with both `Multiple` and `Equal` hints.
- **`linalg.pack`**: standalone tiling, producer fusion, and consumer
fusion (`test.fuse_consumer`), with both `Multiple` and `Equal` hints.
- Negative cases: missing hint falls back to the conservative tiling; a
hint that contradicts statically-known sizes is ignored; transposing
`outer_dims_perm`/consumers confirm source-order (un-permuted) indexing.
- Transform-op attribute verification (`inner_tile_alignments`
validity).

These functions might not be kernels themselves, but are designed to

inlined, and reference LDS, the AMDGPU ISel emits lots of misleading

Fix by changing visibility from external+default to external+hidden,
which allows DCE to just remove the functions.

[VPlan] Optimize pre-increment IV latch users with tail folding (#206499)
This was noticed after #204089 caused IndVarsSimplify to convert some
live out IV users to use the pre-incremented IV, not the
post-incremented.
Tail folded live-outs don't have the `(extract-last-lane
(extract-last-part foo))` form, but instead have the form `(extract-lane
(last-active-lane header-mask), foo)`.
For post-incremented IVs in tail folding, these are converted to
VPInstruction::ExitingIVValue which are handled separately. But
ExitingIVValue can't be used for the pre-incremented IV. So this teaches
optimizeLatchExitInductionUser to detect the last-active-lane of the
header mask form.

sext therefore lets such coordinates fold to the a16 form, reducing VGPR
pressure.

[analyzer][docs] Fix invalid MyST toctree 'numbered' option after Markdown migration (#207217)
The RST-to-Markdown migration (#206181) converted the RST flag
`:numbered:` into `:numbered: true`.
MyST parses the toctree `numbered` option as `int_or_nothing`, so the
string `true` fails with:
```
'toctree': Invalid option value for 'numbered': true:
invalid literal for int() with base 10: 'true'
```
This breaks the `-W` (warnings-as-errors) `docs-clang-html` build.
Make `numbered` a valueless flag, which MyST accepts (equivalent to the
original RST behavior of numbering all levels).

[Clang] Fix crash on subscripting a complete matrix subscript expression (#207317)
Subscripting a complete MatrixSubscriptExpr (which has scalar type)
caused an assertion failure in ActOnArraySubscriptExpr because the code
unconditionally asserted isIncomplete() on any MatrixSubscriptExpr base.
Fix by guarding the matrix subscript path with an isIncomplete() check,
allowing complete matrix subscript expressions to fall through to the
standard subscript handling, which emits an appropriate diagnostic.

[DebugInfo] Truncate implicit value constants to source type width (#206671)
This is a follow-up to #204353.
mikaelholmen and bevin-hansson reported that the previous change could
assert downstream when emitting `DW_OP_implicit_value` for a source
integer type wider than the target generic DWARF stack type, if the
debug-value carrier integer contains bits outside the declared source
type width.
The fix is to construct the source-width `APInt` with explicit
truncation enabled before emitting the implicit value bytes. This
preserves the intended wrap/truncate behavior and avoids asserting on
otherwise recoverable debug-value input.
A regression test is added for an `unsigned _BitInt(48)` debug value on
i386, covering both an out-of-range positive carrier value and an
all-ones negative carrier value.

[SPIRV] Preserve FP types in atomic load/store instead of casting to integer (#194583)
The default
`TargetLowering::shouldCastAtomicLoadInIR`/`shouldCastAtomicStoreInIR`
cast all FP atomics to integer, producing unnecessary bitcasts in SPIR-V
output. Override both to return None, matching the existing
`shouldCastAtomicRMWIInIR` behavior and letting
`OpAtomicLoad`/`OpAtomicStore` operate on FP types directly.
Also updated 16-bit atomics tests from #184312 to use native load/store
atomic instructions now that the SPIRV backend supports them (landed in
#185696).

context rows but only 266 distinct values. Keep the four common opcode
maps as direct tables and intern rows only for these eight sparse maps.
This reduces fully stripped arm64 llvm-mc from 8,333,344 to 6,797,728
bytes, saving 1,535,616 bytes (18.43%). X86Disassembler.cpp.o decreases
by 1,525,328 bytes (52.36%); constant data falls by 1,526,328 bytes
while text grows by 848 bytes. The stripped all-tools multicall binary
decreases from 145,103,200 to 143,567,584 bytes, saving 1,535,616 bytes
(1.058%).

The fold narrows fptrunc(BO(fpext x, fpext y)) -> BO(x, y) for
fadd/fsub/fmul/fdiv, recomputing the binop directly in the narrower
type.
Even if the original BO returns a finite result, the fptrunc may produce
inf. Therefore even if the original BO has ninf, we have to drop it on
the new BO unless the original fptrunc *also* has ninf.

[Clang] Add flags and lang option for C++2d (#203992)
This adds diagnostic groups, command-line options, a language option,
and various other things required to support `-std=c++2d`. I haven’t
touched e.g. clang-tidy or clang-format, as I’m not really familiar w/
either. This is only meant to add the most necessary parts to support
C++29 mode.
I grepped for `CPlusPlus26`/`C++26`/`C++2c` and updated all places I
could find where we need to handle every language mode in some way or
another.
This patch is roughly based on b763d6a4ed4650c74c6846d743156468563b0e31.

[llvm][object] handle GOFF in createObjectFile (#206636)
`ObjectFile::createObjectFile` doesn't handle GOFF and returns an error,
even though the requisite GOFF support is present (i.e.
`createGOFFObjectFile`). This change corrects this, and adds a simple
test for `createObjectFile` on a GOFF type object.

[FileCheck] Call out var captures on unmatched patterns (#206303)
This patch is motivated by an #llvm IRC chat in 2019 with @AaronBallman,
where he pointed out an example similar to following:
```
$ cat input
[[clang::optnone]] void foo() {
$ cat check
CHECK: [[clang::optnone]] void foo() {
$ FileCheck check < input |& tail -7
Input was:
<<<<<<
1: [[clang::optnone]] void foo() {
check:1'0 { } search range (exclusive bounds)
check:1'1 error: no match found
check:1'2 ? possible intended match
>>>>>>
```
It is very easy to miss why that fails. This patch adds one more note
that hopefully clears up the confusion:
```
$ FileCheck check < input |& tail -8
Input was:
<<<<<<
1: [[clang::optnone]] void foo() {
check:1'0 { } search range (exclusive bounds)
check:1'1 error: no match found
check:1'2 pattern attempts to capture variables: "clang"
check:1'3 ? possible intended match
>>>>>>
```
That is, where matching patterns print successful variable captures,
this patch makes unmatching patterns print attempted variable captures.

Instead of using a local variable for the PC, save it in `InterpState`.
Only comparatively few opcodes care about it, but with exceptions, all
calls ops can change the PC. Saving it in the `InterpState` makes it
easier to have opcode implementation jump around in bytecode.

This allows to remove the old

and just rely on the combineToHorizontalAddSub folds from
add(shuffle(x,y),shuffle(x,y)) patterns.

Also adding tests for x87DoubleExtended bit conversion.
initFromF80LongDoubleAPInt was called only twice during in all APFloat
unit tests together. Testing common cases, boundary conditions, and the
special cases documented in IEEEFloat::initFromF80LongDoubleAPInt.

[lldb] Add AMD GPU architectures to ArchSpec (#206369)
## Summary
Teach ArchSpec and ObjectFileELF about AMD (R600 and GCN/amdgcn) GPU
architectures so GPU ELF object files and triples resolve to a precise
architecture.
## Tests:
unit-test the ELF-header -> architecture mapping in ArchSpecTest and an
end-to-end AMDGPU ELF in TestObjectFileELF.
The processor list, e_flags machine values, OSABI and ABI versions
follow llvm/include/llvm/BinaryFormat/ELF.h (AMDGPU_MACH_LIST) and the
AMDGPU code-object spec documented at
https://llvm.org/docs/AMDGPUUsage.html.

[GenericDomTreeConstruction] Speed up Semi-NCA construction (#207474)
Run the immediate-dominator step in DFS-number space instead of chasing
NodePtr IDom through getNodeInfo()/getNumber(), and drop the redundant
NumToInfo[Semi]->DFSNum lookup. Use an inline capacity 32 (sqlite3's p90
is ~29 blocks), with no measurable gain from a larger inline buffer.
NumToInfo and IDoms are filled with resize_for_overwrite: index 0 is an
unused sentinel (DFS numbering is 1-based) and every other slot is
written before it is read, so the value-init and push_back bookkeeping
are dead.
Make getChildren return a lazy filtered range and iterate it directly in
runDFS's common case, instead of materializing a SmallVector per node
just to push its successors onto the worklist.
clang::CFGBlock::AdjacentBlock still needs special handling: it is a
proxy convertible to CFGBlock* that can be null for unreachable edges
(also see commit 7ea0ee30588e), and it is not easy to migrate off.

As suggested in
https://github.com/llvm/llvm-project/pull/187709#issuecomment-4120922355,
this adds documentation for both `S_LOCAL` and the known `S_DEFRANGE*`
records.
In all descriptions, I put struct definition with comments, because it
describes both the layout and the function of each member. Some comments
are from the original PDB repo
(https://github.com/microsoft/microsoft-pdb/blob/805655a28bd8198004be2ac27e6e0290121a5e89/include/cvinfo.h#L4209-L4291).
Many structs in LLVM itself don't have these comments. I think we should
also add them there.

[Support] Remove virtual functions from formatv (#207516)
Currently, formatv erases types using a base class and calls the virtual
function format() to format the objects. To avoid these vtables,
refactor formatv to instead store function_refs to a functor (struct
with overloaded operator()). This saves ~5kiB in vtables.
Additionally, add a static assertion that a formatter is present instead
of relying on errors due to missing templates. This requires a little
change to MLIR's tgfmt to use a different name -- previously, the
substitution failure on ArrayRef<> would cause the variadic function to
be skipped, but a static assertion failure is not a substitution error.
Also, simplify the code in FormatVariadicDetails to use if constexpr
instead of template overloads with enable_if, making the code shorter
and easier to read.

[clang-format] Fix BlockIndent compat mapping of AlignAfterOpenBracket (#207187)
be11e2b3d25 (#192283) replaced the `[[fallthrough]]` chain in the
`AlignAfterOpenBracket` backward-compatibility switch with explicit
per-case assignments. In the `BAS_BlockIndent` case the
`BreakBeforeCloseBracket{BracedList,Function,If} = true` assignments are
immediately overwritten with `false`, and
`BreakAfterOpenBracket{BracedList,Function,If}` (previously inherited
from the `BAS_AlwaysBreak` case via fallthrough) are never set. As a
result, `AlignAfterOpenBracket: BlockIndent` parses to the same flag set
as `Align`, silently dropping the block-indent style for existing
configurations.
Restore the pre-#192283 mapping and pin the full BlockIndent flag
mapping in ConfigParseTest so the compat shim cannot regress silently
again.
Fixes #207186.
Note for the release branch: if #205920 (backport of #192283 to
release/22.x) lands, this fix needs to be backported together with it.

[RISC-V][RVY] Initial ISAInfo support for RVY
RVY is a new base ISA, so the syntax to enable it is rv32y/rv64y.
Since the compressed instructions reuse the space for Zcf (RV32) and
Zcd (RV64), those are marked as incompatible and the logic for C/Zce
is updated as part of this PR.
RVY can also extend RVE instead of RVY (as is done for CHERIoT), but the
official arch string syntax for that has not been finalized yet.
Related discussion on that includes the "long base name" proposal:

(NEONMAP0). The vrnd32/64 builtins use NEONMAP1 entries with their
aarch64.neon.frint* intrinsic names.
The lowering follows the existing implementation in
CodeGen/TargetBuiltins/ARM.cpp.
Prior to this patch, the original neon-intrinsics.c had zero f32
standard rounding tests :
I had added 15 test cases to cover f32 standard rounding tests
(vrnd_f32, vrnda_f32, etc.) in
clang/test/CodeGen/AArch64/neon/intrinsics.c
For this reasons, 30 num-of-new-tests > 15 num-of-deleted-tests.

[LifetimeSafety] Add multi-block support to buildOriginFlowChain (#204592)
After introducing `buildOriginFlowChain` to use-after-scope diagnostics,
it should support multi-block analysis. This also allows it to be reused
by other diagnostics.
In some loops, `UseFact` may appear before `OriginFlowFact`:
```cpp
void for_loop_use_before_loop_body(MyObj safe) {
MyObj* p = &safe;
for (int i = 0; i < 1; ++i) {
(void)*p;
MyObj s;
p = &s;
}
(void)*p;
}
```
So I no longer use `StartPoint` as the initial search starting point; it
is only used to locate the corresponding block.

[InstCombine] Fold commuted add of udiv/urem by two (#206272) (#207462)
Fixes #206272.
`SimplifyAddWithRemainder` folds `(X / C0) * C1 + (X % C0) * C2`,
treating `and X, lowmask` as a remainder and `lshr X, N` as a division.
The commuted form `add (and X, C), (lshr X, N)` was missed because the
operand-order swap only recognized a real `urem`/`srem`.
Now the fold is tried with both operand orders instead of relying on
that swap. Verified with Alive2.
Supersedes #207249 (re-opened from the correct account; already
incorporates the both-operand-orders refactor suggested there by
nikic).
Prepared with AI assistance per the [LLVM AI Tool

issue".

[libc++] Use std::to_chars to format thread::id and canonicalize the representation across platforms (#181624)
This makes printing `thread::id` faster, since we avoid a bunch of
boilerplate code that isn't optimized away. It also avoids including
`<sstream>` and `<__locale>`, cutting the time to parse `<thread>` in
half.
This also changes the output when printing the id on a platform that
uses a pointer as the underlying type. I don't think that's a problem,
since the thread id isn't in any way stable. It also makes the output
consistent across all platforms we support.

- Use processR_PC for PC-relative relocations and processR_PLT_PC for

- Handle TLS LE relocations directly with checkTlsLe.
- Simplify getRelExpr to only handle relocations needed by
relocateNonAlloc and preprocessRelocs.

[MLIR][NVVM]Import llvm intrinsics for nvvm.barrier (#202862)
This PR adds LLVM IR import support for the `bar.sync` intrinsic family,
lifting the four variants into `nvvm.barrier` with the appropriate
`aligned` attribute and optional thread-count operand.
`LLVM_IntrOpBase` and its auto-generated import is one to one, but four
`bar.sync` variants are many-to-one, where they all lift into
`nvvm.barrier`, differing only in `aligned` and the optional
`numberOfThreads` operand.
An alternative implementation would extend mlir-tblgen with many-to-one
intrinsic-to-op mapping support so the conversion could live in
`NVVMOps.td`. But the change is bigger than manually import `bar.sync`
intrinsic family.

[InstSimplify] Fold value-preserving zext/sext of trunc (#204089)
Fold a value-preserving `zext (trunc nuw X)` / `sext (trunc nsw X)` back
to
`X` in `simplifyCastInst` (when the trunc source type equals the extend
result type and the no-wrap flag guarantees the round-trip is identity).
After indvars canonicalizes a min-index loop, the running-index select
has a
`trunc nuw nsw i64 %iv to i32` on its true side while `arr[i]` is
addressed
directly with the i64 `%iv`. When PHI-translating the select-dependent
address along the backedge (see #203863), the true side becomes
`gep base, zext nneg (trunc nuw %iv)`, which has no matching instruction
in
the loop, so the select dependency is never formed and the redundant
load
survives.
Teaching `simplifyCastInst` to collapse the value-preserving
extend-of-trunc
makes the translated address fold back to `gep base, %iv`, matching the
existing `arr[i]` address, so the load through the select index is
eliminated. This fixes the integer min-index variant of
https://github.com/llvm/llvm-project/issues/58569#issuecomment-2788365047
(e.g. returning `minloc` instead of the value).

[RISCV] Remove -riscv-v-fixed-length-vector-lmul-max option (#207312)
Whilst reviewing https://github.com/llvm/llvm-project/pull/207254, I
threw claude at it and it found a crash when passing in a non-default
-riscv-v-fixed-length-vector-lmul-max flag.
This option was added 5 years ago around the time initial fixed vector
support was being added in a719b667a9794, and IIUC it was added so that
support for more LMULs could be added over time.
We don't have any substantial codegen testing for it and I couldn't find
any downstream users either. So rather than trying to fix
https://github.com/llvm/llvm-project/pull/207254 to handle it it seems
easier just to remove it now that fixed vector support for RVV has
matured.

[InstCombine] Skip redundant demanded element queries in insert chains (#205948)
Avoid re-running `SimplifyDemandedVectorElts` on intermediate
`insertelement` chain nodes when a bounded scan proves the top-level
all-lanes query cannot change the IR.
The skip is implemented inside the `InsertElement` case of
`SimplifyDemandedVectorElts` and is limited to the top-level all-lanes
query (`Depth == 0 && DemandedElts.isAllOnes()`). The bounded scan
matches the existing SDVE depth window and only skips chains with
distinct in-range constant insert indices. This keeps the normal SDVE
path for duplicate indices, variable indices, out-of-range indices,
multi-use chains, and the final chain root.
This was motivated by a cutile matmul compile-time case where loop
unrolling produced 128-lane vector insert/extract chains. Before this
change, InstCombine repeatedly invoked SDVE on intermediate
`insertelement` nodes in those chains. On the representative IR, the
affected InstCombine pass time went from about `44.9 ms` to `29.8 ms`,
and total `opt` compile time was reduced by about 20%.
AI disclosure: This patch was developed with assistance from
@openai-codex using GPT-5.5 via [Codex](https://openai.com/codex/). I
reviewed and tested the final changes before submission.

be sure that the callee (from a different module) also reserves the
register.
The responsibility of reserving register and managing it is now on the
user. However, a warning will be displayed if the user tries to reserve a
caller saved register.

[clangd] Null-check AutoTypeLoc in CollectExtraHighlightings::VisitDeclaratorDecl (#207323)
A Decl's getType() can have a getContainedAutoType() without
its TypeSourceInfo's type having one, because the two types
can differ in type sugar such as DecltypeType which
getContainedAutoType[Loc]() deliberately does not look through.

[InlineCost] Never inline functions with incompatible target features (#205113)
If inlining is unsound due to incompatible target feature attributes, we
should not inline the call even if alwaysinline is set. This will likely
result in a crash during instruction selection.
We tried this previously in
https://github.com/llvm/llvm-project/commit/d6f994acb3d545b80161e24ab742c9c69d4bbf33,
but the change had to be reverted because the quality of our
areInlineCompatible() hooks was very bad at the time, which resulted in
inlining not happening in many cases where it was safe.
I think we're in a much better position now. Most notably, we now have a
default areInlineCompatible() implementation that actually does
something sensible (https://github.com/llvm/llvm-project/pull/117493),
inlining compatibility for target features is now specified in TableGen
(https://github.com/llvm/llvm-project/pull/205348). Various
target-specific issues have been fixed as well, e.g. ARM's overly strict
feature whitelist (https://github.com/llvm/llvm-project/pull/205763) and
X86's overly conservative ABI compatibility checks
(https://github.com/llvm/llvm-project/pull/205106).

[libc++] Split the multidimensional algorithms out of uninitialized_algorithms.h (#207447)
While these algorithms are conceptually related to other

by `shared_ptr`. `uninitialized_algorithms.h` itself is also getting
rather large, so it makes sense to split the multidimensional versions
into their own header.

Original LASX signed/unsigned 64-bit integer & floating point will
suffer from double rounding issue, due to it implements such logic: `i64
-> double -> float` that will lead to precision loss. So delete it and
introduce the `[X]VFFINT.S.L` instruction, which could convert 4 or 8
signed 64-bit integer into float in one instrunction.
Also, create the `MergeBlocksConvert` helper function to reuse the logic
about merge two blocks into one, avoid unnecessary code size bloat.

Building with `-fvisibility=hidden` is generally a good idea, since it

should be a no-op, since most things are annotated explicitly. By
enabling `-fvisibility=hidden` we can remove these explicit annotations
however.

[ADT][NFC] Use isEqual for ImmutableSet/Map tree canonicalization (#207596)
`ImutAVLFactory::getCanonicalTree` deduplicates a newly built tree
against the trees already in its cache. On a digest collision it
confirmed structural equality with `compareTreeWithSection`, a plain
element-by-element in-order walk that is always linear in the tree size.
`ImutAVLTree` already provides `isEqual`, which performs the same
structural comparison but skips subtrees that are shared by pointer.
These persistent trees are heavily structurally shared -- a tree
produced by `add`/`remove` shares everything but the mutated spine with
its predecessor -- so switching `getCanonicalTree` to `isEqual` reduces
the confirmation from `O(tree size)` to `O(number of differing nodes)`
in the common case, and is never asymptotically worse. The comparison is
exact, so canonicalization behavior is unchanged.
This builds on the recent iterator rewrite in #205552 ("Rewrite
ImmutableSet/Map in-order iterator without per-node state"), which made
in-order traversal and `skipSubTree` ~2x faster. That change is a
constant-factor speedup of the iterator primitive and it deliberately
preserved `skipSubTree`/`isEqual` semantics; this patch is complementary
and algorithmic: it routes canonicalization through the pointer-skipping
`isEqual`, cutting the number of nodes visited rather than the per-node
cost. The two compose -- the remaining traversal here runs on the faster
iterator from #205552.
This confirmation is the dominant cost of `ExplodedGraph`
canonicalization in the Clang Static Analyzer whenever many equivalent
`ProgramState`s are kept live and re-derived on different paths (for
example with node reclamation disabled): each re-derivation of an
already-cached `Environment`/`Store` map paid a full in-order walk to
confirm the match. On several large reproducers the analyzer's
`ImutAVLFactory` node comparisons dropped by ~26-36x with identical
diagnostics and identical `ExplodedGraph` node/step counts. (These
measurements already include #205552, so this speedup is on top of that
iterator win.)
`compareTreeWithSection` had no other callers and is removed.
## Analyzer wall-clock
Measured on the three reproducers from
https://github.com/llvm/llvm-project/issues/105512#issuecomment-2389083480,
best-of-3 wall-clock, `RelWithDebInfo` on an Apple M-series host. "ON"
is the default; "OFF" disables node reclamation (`-analyzer-config
graph-trim-interval=0`), the configuration that exposes the cost:
| Reproducer | Config | Before | After | Speedup |
| ------------ | ------ | -------- | ------- | ------- |
| ruby-unicode | ON | 2.18 s | 2.06 s | ~1.0x |
| ruby-unicode | OFF | 11.97 s | 2.28 s | ~5.2x |
| linux-topro | ON | 5.26 s | 5.08 s | ~1.0x |
| linux-topro | OFF | 11.16 s | 5.21 s | ~2.1x |
| MSP430 | ON | 2.71 s | 2.65 s | ~1.0x |
| MSP430 | OFF | 7.58 s | 2.71 s | ~2.8x |
The default (ON) path is unchanged within noise; the OFF path drops from
2.1-5.5x slower than ON to parity.
## Microbenchmark
Add a `CanonicalizeSharedEqual` case to `ImmutableSetIteratorBM`
covering `getCanonicalTree`/`isEqual`. It re-canonicalizes a freshly
built tree that is equal to, and shares subtrees with, a cached tree
(`RelWithDebInfo`, same host):
| Set size `N` | Before | After | Speedup |
| ------------ | --------- | ------- | ------- |
| 16 | 212 ns | 186 ns | ~1.1x |
| 256 | 1354 ns | 347 ns | ~3.9x |
| 4096 | 21603 ns | 547 ns | ~40x |
| 65536 | 677240 ns | 1015 ns | ~667x |
The existing `Iterate`/`Skip`/`CompareSamePos` cases are unchanged; this
does not touch the iterator.

[X86] Attempt to narrow XMM->i64 (v)movq -> (v)movd if the upper 32-bits are known to be zero (#207615)
Add a custom 'X86upperzero' tablegen pattern to match vectors where the
upper half bits of every element is known zero.
Saves 1 byte by using (V)MOVD instead of (V)MOVQ - and avoids
differences in X86/X64 codegen that was bloating diffs in some upcoming
VECREDUCE_ADD work.
I've added an extra psadbw.ll test to ensure that the extractstore
pattern isn't being affected.
Cleanup for the upcoming VECREDUCE_ADD handling which will be using
PSADBW more aggressively (v2i64 result type but only 16 active bits for
element).

[lldb] Guard DW_OP_convert against null DWARF unit and empty stack (#207008)
`Evaluate_DW_OP_convert` dereferenced `eval_ctx.dwarf_cu` (the
`DWARFExpression` Delegate) whenever the operand DIE offset was
non-zero,
and unconditionally read `eval_ctx.stack.back()`. When a DWARF
expression is evaluated without a DWARF unit (as the
lldb-dwarf-expression-fuzzer does), two operand shapes crash:
- `DW_OP_convert` with a non-zero offset calls
`dwarf_cu->GetDIEBitSizeAndSign(...)` on a null Delegate.
- `DW_OP_convert` with nothing on the stack reads the back of an empty
vector.
The unit test feeds both with `dwarf_cu == nullptr` and crashes:
```
[ RUN ] DWARFExpression.DW_OP_convert
#2 SignalHandler(int, __siginfo*, void*)
#4 DWARFExpression::Evaluate(...)
#5 Evaluate(ArrayRef<unsigned char>, ...)
```
(SIGSEGV, the process aborts.)
Bail out with an error when the stack is empty, and when a non-zero DIE
offset is requested without a DWARF unit, instead of crashing.
Extends `DWARFExpression.DW_OP_convert` with these two cases, which
crash
without the fix.

[lldb][test] Add expedited-stack-memory backtrace/locals packet test (#205897)
Add a Darwin API test that checks which gdb-remote packets lldb sends
while
inspecting the stack at a public stop, using the gdb-remote packet log
(the
same approach as TestExpeditedThreadPCs.py).
debugserver expedites the frame-pointer backchain in the `jThreadsInfo`
reply
at a public stop and lldb caches it, so:
- A backtrace (`GetNumFrames` + `GetFrameAtIndex` over every frame)
sends no
packets at all. With the memory cache disabled it must read the
backchain
frame by frame, which confirms the test exercises the unwinder's memory
reads.
- Examining frame locals is not covered by the expedite, so it reads
value
memory. The reads are classified as stack vs heap using the variables'
own addresses (known from main.c).
Locals are examined two ways, modeling how an IDE inspects values at a
stop:
walking the whole stack but examining only the selected frame's locals
(frame 0, as a variables view does on a stop), and examining every
frame's
locals (a "view all frames" mode). The stopped frame (`func_e`) carries
scalar,
aggregate, and pointer-to-heap locals so frame 0 alone reads both stack
and
heap memory; the outer frames keep locals so the all-frames case reads
the
same variety across several frames. Values are read with
`use_dynamic=eDynamicCanRunTarget` to match how an IDE reads them.

[lldb] Reject NULL key in PythonDictionary::GetItem (#205753)
A `breakpoint set -P <class>` with an invalid-UTF-8 class name crashes
lldb with `EXC_BAD_ACCESS`. The class name is passed through
unmodified, so the byte sequence `\xd0p` (an incomplete two-byte UTF-8
sequence) reaches the Python layer:
```
./bin/lldb -b -o $'breakpoint set -P \xd0p -f main.cpp' ./bin/lldb
...
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/
Stack dump:
#4 PythonDictionary::GetItem(PythonObject const&) const
#6 PythonDictionary::GetItemForKey(PythonObject const&) const
#7 PythonObject::ResolveNameWithDictionary(StringRef, PythonDictionary const&)
#9 ScriptedPythonInterface::CreatePluginObject<...>(...)
```
`ResolveNameWithDictionary` builds a `PythonString` from the class name
and looks it up in the module dictionary. When the name is not valid
UTF-8, `PyUnicode_FromStringAndSize` returns `NULL`, so the
`PythonString` is left with `m_py_obj == NULL`. `GetItemForKey` forwards
that object to `GetItem`, which passed the `NULL` `PyObject *` straight
to `PyDict_GetItemWithError`.
Debugging the crashing lldb under lldb shows the `NULL` key arriving in
`GetItem`:
```
(lldb) break set -n lldb_private::python::PythonDictionary::GetItem
(lldb) run --no-use-colors -b -s /tmp/bp_cmds.txt
* stop reason = breakpoint 1.1
(lldb) up
(lldb) frame variable key.m_py_obj
(PyObject *) key.m_py_obj = nullptr
```
Continuing lands on the dereference of that `NULL` inside CPython:
```
(lldb) continue
* stop reason = EXC_BAD_ACCESS (code=1, address=0x8)
frame #0: PyDict_GetItemWithError + 40
-> ldr x8, [x1, #0x8]
```
`x1` holds the key argument, which is `NULL`, so reading the type field
at offset `0x8` faults at address `0x8`.
`GetItem` already guards against an invalid dictionary (`!IsValid()`);
extend that guard to reject an invalid key as well and return
`nullDeref()`. `GetItemForKey` consumes the error and returns an empty
`PythonObject`, so existing callers such as `ResolveNameWithDictionary`
keep working and the breakpoint command now fails cleanly instead of
crashing.
This was found by `lldb-commandinterpreter-fuzzer`.
Adds `PythonDataObjectsTest.TestPythonDictionaryGetItemWithInvalidKey`,
which feeds an invalid-UTF-8 key to `GetItem`. Without the fix the test
dereferences the `NULL` key and crashes (`SIGSEGV`).

Reapply [IR] Explicitly specify target feature for module asm (#204548) (#207677)
Reapply with a use-after-free fix. The MC subtarget used for inline
assembly has to stay alive until finalization, not only during the
emitInlineAsm() call.
-----
Support specifying additional properties on module-level inline
assembly. In particular, the target features and target CPU can now be
specified as follows:
module asm(target_features: "+foo", target_cpu: "bar")
"asm line 1"
"asm line 2"
There may be multiple module inline assembly blocks with different
properties.
This is intended to fix the long standing issue where in LTO scenarios
we don't know what target features to use for parsing the module-level
inline assembly. Now they can be faithfully preserved, even when merging
inline assembly from different modules with different features.
If target_features and target_cpu are empty, we fall back to the old
behavior (which, in the backend, would be to use the default subtarget
of the TargetMachine).
Fixes https://github.com/llvm/llvm-project/issues/61991.

[offload] Fix duplicate __llvm_write_custom_profile on Windows PGO builds (#207366)
MSVC/clang-cl lack __attribute__((weak)), so GlobalHandler.cpp provided
a strong stub for __llvm_write_custom_profile. When clang_rt.profile is
linked (e.g. instrumented/PGO builds) lld-link rejects the duplicate
strong symbol.
Replace the stub + CMake workaround with the /alternatename linker
pragma, which is the standard Windows weak-symbol equivalent used by
compiler-rt itself. The linker picks compiler-rt's strong definition
when present.
Fix the guard: use _WIN32 && !__MINGW32__ (not _MSC_VER) so the stub and
/alternatename pragma apply to plain clang-on-Windows too, while MinGW
(which supports __attribute__((weak)) natively) continues to use the
real weak declaration.
Also fix the stub signature from 8 to 10 parameters to match the header.

[llvm-dwarfdump][LineCov 3/3] Add IR analysis for variable coverage (#195342)
Patch 3 of 3 to add to llvm-dwarfdump the ability to measure DWARF
coverage of local variables in terms of source lines, as discussed in
this RFC:
https://discourse.llvm.org/t/rfc-debug-info-coverage-tool-v2/83266
This patch adds an IR-level analysis in order to more accurately compute
the defined ranges for each variable. This avoids the problem of the
more naïve approach relying on source scopes, which overcounts as
coverable those lines where the variable is not yet defined (e.g. stack
variables).
The IR analysis requires IR to be provided to llvm-dwarfdump as a
separate `--variable-coverage-bitcode-file` argument (either textual IR
or bitcode; can be produced by various means e.g. `--save-temps
--emit-llvm`, `-ffat-lto-objects`,
[wllvm](https://github.com/travitch/whole-program-llvm)). The
recommended way to obtain a whole-program bitcode file is to use wllvm
as follows:
```sh
$ export LLVM_COMPILER=clang
$ CC=wllvm make # build as usual, but replace clang/clang++ with wllvm/wllvm++
$ extract-bc binfile # produces binfile.bc, which can be passed to llvm-dwarfdump
```

[RISCV] Fold vp.reverse of vp.load through binary ops (#205529)
InstCombine canonicalizes reverses, including vp.reverses, by pulling
them through binary ops: https://godbolt.org/z/cs4M1TsE3
We have a combine that converts vp.reverses of vp.loads into
vp.strided.loads with a stride of -1, but it only matches the pattern
`vp.reverse(vp.load)` directly.
This PR teaches the combine to look through binary ops for vp.loads so
it can match the canonicalized form when there's a binary op that uses
the vp.reverse.
All leaves must be either a vp.load or a splat, but it still will only
convert one vp.load at a time. This combine isn't always profitable so
we should eventually remove it when it's done somewhere that's cost
model driven like the loop vectorizer or vector combine.

[MergeICmps][DebugInfo] Preserve debug locations in mergeComparisons (#205796)
The mergeComparisons function in MergeICmps merges a chain of comparison
blocks, generating new instructions inside of the merged block(s) to
memcmp the contiguous blocks of memory being compared and perform a
single branch based on the result. Some of the generated instructions
take their debug locations directly from the first block in the
comparison chain, but the icmp/memcmp and branch instructions generated
are not assigned any debug location.
This patch assigns a debug location to the comparison instructions from
the merged location of all merged comparison instructions, and similarly
assigns the branch instruction from the merged branch instructions.

[orc-rt] Add SPSSequence serialization from iterator_range. (#207715)
Adds an SPSSerializationTraits specialization that serializes an
iterator_range<IteratorT> as an SPSSequence<SPSElementTagT>, matching
the wire format of the existing container and span sequence serializers.
The element type is deduced via std::iterator_traits, so both class-type
iterators and raw pointers are supported.
This lets callers serialize an arbitrary [begin, end) sub-range
directly, without first copying the elements into a temporary container.
Only serialization is provided: a bare iterator pair has no meaningful
deserialization target, so decode into a std::vector (or other sequence
type) as usual.

[mlir][tosa] Add new block-scaled tensor type and support for MXFP CAST (#203583)
This commit adds a new compound-block scaled tensor type and uses this
type to implement support for MXFP in the CAST operation, as per the
following specification changes:
https://github.com/arm/tosa-specification/pull/50,
https://github.com/arm/tosa-specification/pull/53.
The new block-scaled type is closely modelled after the `quant` dialect
type and supports the following parameters:
- block shape - The size and axis of each block. Support for specifying
constant scale values has not been added in this commit, but will be
added in a later one.
- scale type - The type of the scale value associated with each block.
- value type - The type of the data values in each block.
Example syntax for the new block-scaled type:
```
tensor<160x!tosa.block_scaled<BLOCK_SHAPE_32:f8E8M0FNU:f8E5M2>>
```
As a pre-requisite for supporting MXFP CAST, the commit also adds new
extensions intended to split the existing EXT-MXFP extension into
separate extensions for each block-scaled type. This allows for more
fine-grained control over which block-scaled types are supported by a
given target. See specification change
https://github.com/arm/tosa-specification/pull/26 for details.
Finally, support for casting to/from the new block-scaled type has been
added, aligning with the behaviour specified in the CAST operation
specification.

[Clang][ExprConstant] Normalize aux target builtin IDs before dispatch (#201805)
When compiling for a device target that has an auxiliary host target
(for example OpenMP or CUDA offload), builtins of the auxiliary target
are registered with IDs shifted past the primary target's builtins. The
constant evaluator passed the raw ID straight into the target-specific
evaluation switches in the Pointer/Int/Vector/Float expression
evaluators, so a shifted auxiliary ID could fall through to an unrelated
builtin's case (or miss its case entirely) and fail to fold.
Add a getConstantEvaluatedBuiltinID() helper that translates auxiliary
builtin IDs back to their canonical target IDs via
BuiltinInfo::getAuxBuiltinID(), and use it before dispatching in each of
those evaluators.

[InstCombine] Propagate debuglocs when replacing insert->extract elts (#206026)
InstCombine may replace an extractelement->insertelement chain, where
the insert vector is wider than the extract vector, with a pair of
shufflevectors - one to widen the extract vector, and one to perform the
extract+insert simultaneously. Currently the second shufflevector
correctly adopts the insertelement's debug location, since it replaces
the chain of instructions that culminates with the insert. The first
shufflevector however takes its debug location from its insert position,
if the extract vector was a PHI or non-instruction, and otherwise
receives no location.
Since the first shufflevector is really adapting the extract vector for
use by one or more other instructions, we can consider it an extension
of the extractvector. If the extract vector is an instruction, its debug
location should be used (even if it is a PHI - this likely defaults to a
CompilerGenerated debug location); otherwise, the extract vector is a
constant, and so the shufflevector represents a constant materialization
- so should receive a CompilerGenerated location.

[ORC] Track __emutls_t definitions in IRMaterializationUnit (#207161)
When emulated TLS is enabled, `IRMaterializationUnit`'s constructor
emits an `__emutls_t.<var>` symbol for each non-zero-initialized
`thread_local` global and records it in `SymbolFlags`, but never adds it
to `SymbolToDefinition`.
If the same weak (`linkonce_odr`) definition is materialized by more
than one module — e.g. an `inline` function that odr-uses such a
`thread_local`, pulled into two `PartialTranslationUnit`s by clang-repl
— `JITDylib::defineImpl` discards the duplicate via
`IRMaterializationUnit::discard()`. `discard()` looks the symbol up in
`SymbolToDefinition` and, finding nothing, dereferences `end()`: an
assertion failure in `+Asserts` builds and heap corruption otherwise.
Register `__emutls_t.<var>` in `SymbolToDefinition` alongside its flags,
mirroring the `__emutls_v.<var>` handling just above.
### Test
`clang/test/Interpreter/emulated-tls.cpp` reproduces the crash through
clang-repl: two PTUs each odr-use one `inline worker()` that reads a
non-zero `thread_local`, so each re-emits the same weak emulated-TLS
set; defining the second module runs `discard()` over the duplicate. The
test aborts on the unfixed path and prints the expected value with the
fix.

[scudo] Remove internal linkage from LargeBlock header helpers (NFC) (#207708)
`addHeaderTag` and `getHeader` are static function templates in
`secondary.h,` so any TU that includes the header without using them
trips `-Wunused-template`. Dropping static fixes the warning.
Part of #202945.

[clang][AST] Outline constant-interpreter shift diagnostics (#202633)
CheckShift is instantiated for each primitive left-hand and right-hand
type
and for both shift directions. Its four diagnostic paths are cold, but
each
instantiation currently emits the diagnostic construction and undefined
behavior handling.
Move those paths to the non-template, noinline diagnoseShiftFailure
function.
Valid shifts retain the existing checks and do not call the outlined
function.
Invalid shifts preserve the same diagnostic arguments and call
noteUndefinedBehavior exactly once.

[clang-tidy] Compact the confusable identifier table (#202626)
Encode confusable replacement strings once in a shared UTF-8 byte array.
Each sorted mapping becomes an eight-byte code point, 16-bit offset, and
16-bit length entry instead of reserving nineteen UTF-32 code points for
every replacement.
ConfusableIdentifierCheck appends the UTF-8 slice directly after the
binary search, removing the per-identifier UTF-32 to UTF-8 conversion.
Add compile-time assertions for the eight-byte entry layout and the 64
KiB replacement-data limit, plus generator-side overflow checks.
The logical table shrinks from 508,400 to 63,327 bytes, saving 445,073
bytes. A stripped standalone clang-tidy shrinks from 91,116,608 to
90,654,176 bytes, saving 462,432 bytes (0.508%).
A lookup microbenchmark improves from 79.9 to 40.4 ns median. A
100,000-identifier clang-tidy benchmark improves from 0.343 to 0.314
seconds mean.

If the function types of the functions in the jump table don't match the

could avoid that by using a different API, but the usefulness of the
transform in this case is questionable (e.g. we wouldn't be able to
inline the call). For simplicity just bail out.

[Clang] Reduce the number of ways we have to print a codepoint. (#206990)
In #206326, we introduced yet another way to format a codepoint, so we
try to claw back some consistency.
- When we display a single character we do so inside quotes
- Non-decodable code units are displayed as <0xYY>
- In strings
- we render printable and format characters
- we print <U+XXXX> for non printable, non-format characters
- In characters
- we only render non-format print characters
- we always print the codepoint as U+XXXX for non-ascii characters
This does not change `WriteCharValueForDiagnostic` which is deeply weird
and was contentious a while back.
So we still have 2 different formatting utilities. Which is better than
4!
I've also added a test for invalid utf-8 in \N{}

The scaling rewrite patterns are written for scalar/vector values.
Tensor values should not be rewritten by these patterns, so this patch
returns failure for tensor operands and leaves those ops unchanged.
A regression test is added for the tensor reproducer from #207311.

[flang][HLFIR] Relax InlineElementals to support more than two users (#186916)
This pr optimizes the lowering of MINLOC and MAXLOC when the MASK
argument is a simple equality comparison (e.g., MASK = A == X).
This patch introduces isEqualityMask to identify these patterns and
inline the comparison directly into the reduction loop.
This allows the SimplifyHLFIRIntrinsicscation pass to extract the
invariant
search target and bypasses the creation of a temporary logical mask
array
by inlining the equality comparison directly into the reduction loop.
optimization removes the 'hlfir.apply' to the mask's hlfir.elemental,
which
gets eliminated in bufferize-hlfir pass.
Simplifies the reduction state by removing the min/max value tracker,
as the target value is already known.
Implements a 'first-hit' locking mechanism.

[ClangLinkerWrapper] Use discrete steps in verbose mode (#204186)
Summary:
One persistent problem with the linker wrapper flow is that it was more
difficult to reuse as a script than the previous flow. This is because
it did a lot of work internally. In the past we moved al ot of this into
dedicated LLVM tools, so now it's possible to simply use these tools
instead.
This PR changes the verbose mode handling to defer steps to tools rather
than doing it internally. This allows users to use verbose printing and
can copy/paste the results to re-run the steps.

[LoopInfo] Reuse DomTree's own DFS numbering in analyze() (#207650)
analyze() discovers loop headers with a post_order(DomRoot) walk, then
tests each back-edge candidate with DomTree.dominates(). Initial queries
use `dominatedBySlowTreeWalk` and then switch to `updateDFSNumbers`
(Euler tour technique), requiring two tree walks in total.
Optimize this with an upfront updateDFSNumbers to avoid the post-order
walk. Both post-order and reverse pre-order satisfy the
child-before-parent (bottom-up) property. This does change the order in
which siblings are visited (reverse preorder visits the last child
first; post-order visits it last), but that has no observable effect:
the sub-loop and block vectors are only populated by the separate
PopulateLoopsDFS traversal afterward, not by discovery order.
`post_order` (and `depth_first`) are also inefficient for tree
traversals:
DomTreeNodeBase doesn't expose graph numbers, so they fall back to
tracking visited nodes in a SmallPtrSet. For a tree this bookkeeping is
unnecessary, since by definition every node has exactly one parent and
can never be reached twice.
DFS numbers, of [0, 2*N), have many nullptr gaps. Simplify
updateDFSNumbers() so DFSNumOut no longer consumes its own counter tick:
DFSNumIn becomes a dense [0, N) preorder rank.

[flang][cuda] Make the second LAUNCH_BOUNDS() operand optional (#207273)
The minimum-blocks-per-multiprocessor (second) and maximum-blocks-per-cluster
(third) operands of the CUDA Fortran `LAUNCH_BOUNDS()` prefix are optional, as in
CUDA C++ `__launch_bounds__`. A single-operand `LAUNCH_BOUNDS(N)` is now accepted;
1, 2, or 3 integer constants are valid.
Previously `LAUNCH_BOUNDS(N)` with a single operand was rejected, and the
diagnostic path dereferenced an empty `std::optional` (`currStmtSource()`). That
handler runs during the direct statement walk in `ResolveSpecificationParts`,
where the statement source is not set, so the dereference aborted the compiler.
The diagnostic source is now derived from the prefix, and the same fix is applied
to every diagnostic in the `LAUNCH_BOUNDS()` and `CLUSTER_DIMS()` handlers.
When only the maximum-threads-per-block operand is present, the
`cuf.launch_bounds` attribute omits `minBPM` (now an optional parameter) and no
`nvvm.minctasm` attribute is generated.

Migrate tests that would otherwise fail when the `-emit-visible-modules`

* Also remove `command-line` fields that were not actually checked in
tests.

Make clang analyzer's CFG behave like other graphs in the generic
dominator tree builder by teaching the CFGBlock GraphTraits two things.
* Node numbers: getNumber/getMaxNumber/getNumberEpoch backed by the
dense, never-renumbered BlockIDs. GraphHasNodeNumbers<CFGBlock *>
becomes true (#101706) so Semi-NCA indexes a SmallVector instead of a
DenseMap and DominatorTreeBase drops its CFGBlock-to-index map.
* Plain `CFGBlock *` children: map through the reachable target and skip
`AB_Unreachable` (null) edges. This drops the
is_same_v/make_filter_range
fallback in getChildren() and the CFGBlock ChildrenGetterTy
specialization.
(Post)dominator and IDF results are unchanged.

[clang][tablegen] Allow qualifiers on _Vector builtin types (#207091)
The builtin prototype parser accepts pointers to _Vector<> template
types but not const/volatile/restrict pointers. Currently, _Vector<>
types are parsed in a special way: first parsing the type itself,
consuming it, and saving the resulting type string. Then, the remaining
qualifiers are parsed while the type is removed from the input. For this
to work, parsing qualifiers must accept empty base type, which was the
case only for plain pointers and references.
This change extends this approach to const/volatile/restrict qualifiers.

## Summary
- Fix `sandboxir::PassManager::setPassPipeline` to resume scanning pass
names after a pass aux argument when the next token is a delimiter.
- Add a unit test covering flat pipelines like `foo(aux1),bar`.
This fixes parsing of region pass pipelines such as
`bottom-up-vec(top-down),tr-accept` that will be used by the
SandboxVectorizer.
## Test plan
- [x] `ninja SandboxIRTests`

[scudo] Make death tests use SCUDO_XXX_DEATH_TEST. (#206196)
On Android, we want to disable the tombstone generation on expected
crashes to speed up running the tests. Also, this means that any
tombstone files will be real crashes and it's not necessary to search
for the right tombstone if one of the tests crashes unexpectedly.
In order to do the above, add SCUDO_EXPECT_DEATH_TEST and
SCUDO_ASSERT_DEATH_TEST that will disable tombstoned on Android but do
nothing on all other platforms.

[lldb] Move RegisterInfo and RegisterSet into their own header (#207286)
RegisterInfo holds onto a pointer to RegisterFlags which is in
lldbUtility. My understanding of lldb-private-types is that it contains
types used throughout LLDB but should generally stand on their own (i.e.
without dependencies on specific lldb types and headers). Thus I am
moving it to lldbUtility.
RegisterSet _does_ stand on its own but it is pretty strongly coupled to
RegisterInfo.

ValueTracking: Improve frexp known range from dominating conditions (#206927)
Try to restrict the known range of the exponent result of llvm.frexp
based on dominating conditions. Identify comparisons that imply the
incoming value cannot introduce an overflow in a downstream ldexp
use. This pattern appears in the implementation of some complex math
functions and allows finite only math to prune out more edge case
paths.
One attributor test for ldexp regresses due to the switch from
computeKnownBits to computeConstantRange. computeConstantRange
does not try to handle non-splat vector constants for the binary
operators.
As a side effect, this also improves knowing that ldexp can't
introduce overflow for the 0 case.

[LowerBufferFatPointers] Correctly handle alignment modes (#134329)
Previously, AMDGPULowerBufferFatPointers would emit unaligned buffer
loads/stores, even when such unaligned accesses were disabled (that is,
on non-HSA platforms).
In addition, the lowering did not respect the newly-added
amdgpu.buffer.oob.mode module flag, which now must be enabled in order
to vectorize unaligned loads from buffers.
This commit fixes both issues and adds tests.

[AMDGPU] Precommit for pulling NUW large buffer offsets into SOFFSET (#207795)
This commit adds tests with larger constant offsets [being added to
VGPRs] in raw.buffer.* instructions to show the movement of such offsets
to SOFFSET after rounding in a future commit if this won't cause errors
because of overflow.
This also necessitated adding gfx1250 tests (to show the different
offset sizes) and moving tests that ctalled "export" into a new file so
that the gfx1250 (which doesn't support that instruction) doesn't trip
ot those tests.
This also adds a few global-isel specific tests for handling `or
disjoint` like an add we can't just stick -global-isel in the normal
buffer intrinsic tests.
AI usage disclosure: AI wrote these, I skimmed them.

[Clang] Enable -Wunused-template under -Wall (#206123)
Uncomment `UnusedTemplate` in the `Unused` diagnostic group so
`-Wunused-template` becomes part of `-Wall`.
`-Wunused-template` flags unused function and variable templates with
internal linkage. In a header, such a template gives every translation
unit its own internal-linkage copy, which is a latent ODR violation
(ill-formed, no diagnostic required), so enabling this surfaces a real
class of bugs and keeps the pattern from reappearing.
### Depends on
The in-tree occurrences were cleaned up first in a series of NFC PRs
tracked by #202945. This change only builds clean once those land, so CI

[lldb] Remove ConstString from SectionList::FindSectionByName (#207296)
By having ConstString in this interface, we are forcing callers to
create a ConstString in order to perform a lookup. In many cases,
`FindSectionByName` is a best-effort interface, meaning we're creating
ConstStrings speculatively. In other cases, we were creating a
ConstString at the call-site instead of computing it once and re-using
it.
I audited all the callsites and changed all the callsites that created a
ConstString for the purpose of calling `FindSectionByName`. Other
callsites will take more time to change.

didn't do a good job at finding the best RecordDecl to build the GEP off

[Support] Fix undefined shift in decodeULEB128/decodeSLEB128 for overlong encodings (#205907)
When a (signed or unsigned) LEB128 value is encoded with extra trailing
bytes that only carry zero- or sign-extension, the decode loop could
keep
running with the shift amount at 64 or beyond and then evaluate
`Slice << Shift`, which is undefined behavior for a 64-bit type.
The DWARF expression parser feeds attacker-controlled LEB128 operands
(such as `DW_OP_bregN` / `DW_OP_constu`) through
`DataExtractor::getULEB128` / `getSLEB128`, so the
`lldb-dwarf-expression-fuzzer` reaches this under UBSan. The unsigned
case:
```
LEB128.h:152:20: runtime error: shift exponent 70 is too large for
64-bit type 'uint64_t' (aka 'unsigned long long')
#0 llvm::decodeULEB128(...) LEB128.h:152
#1 getLEB128<unsigned long long>(...) DataExtractor.cpp:227
#2 llvm::DataExtractor::getULEB128(...) DataExtractor.cpp:241
#3 llvm::DWARFExpression::Operation::extract(...) DWARFExpression.cpp:218
#7 lldb_private::DWARFExpression::Evaluate(...) DWARFExpression.cpp:1333
#9 LLVMFuzzerTestOneInput lldb-dwarf-expression-fuzzer.cpp:83
SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior LEB128.h:152:20
```
and the signed case, reached the same way:
```
LEB128.h:190:20: runtime error: shift exponent 70 is too large for
64-bit type 'uint64_t' (aka 'unsigned long long')
#0 llvm::decodeSLEB128(...) LEB128.h:190
#1 getLEB128<long long>(...) DataExtractor.cpp:227
#2 llvm::DataExtractor::getSLEB128(...) DataExtractor.cpp:245
#3 llvm::DWARFExpression::Operation::extract(...) DWARFExpression.cpp:216
#7 lldb_private::DWARFExpression::Evaluate(...) DWARFExpression.cpp:1333
```
The existing range checks already guarantee that once `Shift` reaches 64
the remaining bytes are pure extension and contribute nothing to the
result, so skip the accumulating shift in that case. Decoded values are
unchanged for all well-formed inputs.
Adds overlong-encoding regression cases to `LEB128Test`. Without the fix
the signed case is the UBSan diagnostic above in a sanitizer build, and
in a normal build the unsigned case also decodes to the wrong value (the
overlong `1` decodes as `11`).

[llvm][DebugInfo] Add DW_LNAME_ support to DWARFDie::getLanguage (#207151)
Currently `DWARFDie::getLanguage` only looks at `DW_AT_language`.
However, with DWARFv6 we may not have such attribute, and instead have a
`DW_AT_language_name` (and optional `DW_AT_language_version`).
This patch adjusts the implementation to also consider the DWARFv6
language name/version codes. In this patch I just convert it back to
`DW_LANG_` (similar to what we do for the `AsmPrinter`'s
`DwarfUnit::getSourceLanguage`). Added a FIXME to investigate whether we
want to return a variant-like type that can be either an DW_LANG vs.
DW_LNAME code.
The way I initially observed this was looking at a DWARFv6 dwarfdump for
a `const char[]` type. It displayed as follows:
```
DW_AT_type (0x... "const char[[?, ? + 3)]")
```
which is our representation for when we [can't derive the default lower
bound for the
language](https://github.com/llvm/llvm-project/blob/ce787718c3c82255825ebe5f95740c24df55f7d0/llvm/include/llvm/DebugInfo/DWARF/DWARFTypePrinter.h#L122-L135).
With this patch, we'd display it as expected:
```
DW_AT_type (0x... "const char[3]")
```
Added unit-tests for the new API and a dwarfdump test.
AI usage:
- Claude wrote the dwarfdump and unit-tests. Manually reviewed and
cleaned them up.

[clang] Reland: fix getTemplateInstantiationArgs (#207825)
Relands https://github.com/llvm/llvm-project/pull/199528
Previous: https://github.com/llvm/llvm-project/pull/202088
This implements a new strategy for collecting the template arguments, by
relying on the qualifiers and template parameter lists to navigate the
template
context of out-of-line definitions.
This greatly simplifies the signature of that function, by removing a
bunch
of workarounds, and simpliffying a couple that weren't removed yet.
Since this now relies on qualifiers and template parameter lists,
this patch expends most of its effort making sure these are placed,
transformed and propagated to template instantiations.
Also makes the explicit specialization AST nodes stop abusing the
template
parameter lists by storing it's own template parameter list, creating a
dedicated field for them, similar to partial specializations.
Fixes #202106

[clang] Cap MS RTTI TypeDescriptor name strings like MSVC does (#206317)
On the Microsoft ABI, an RTTI TypeDescriptor stores the type's decorated
name as an inline string. Unlike symbol names, this string was never run
through the MD5 shortening that MSVC applies to over-long decorated
names. Deeply nested template types therefore produced unbounded
writable .data COMDATs: for example a type whose template arguments
contain a local lambda, whose mangled name re-spells the enclosing
template context at every level of nesting, grows exponentially with
depth. A five-level repro emitted an 82 MB object file.
Wrap the TypeDescriptor name string in the same msvc_hashing_ostream
already used for the RTTI symbol. When the name reaches the length limit
it is replaced by ??@<md5>@, mimicking MSVC. MSVC counts the leading .
of the name string toward the 4096-character limit but excludes it from
the hashed input, so the threshold here is one lower than for symbols.
Fixes #206313

[Clang][HIP] Add LLVM vendored device headers for `*-llvm` triple (#203980)
Summary:
We already have the `*-llvm` vendor triple to imply a hermetic LLVM
toolchain for HIP. This adds the device portion of the headers that can
be used without a ROCm installation. These are vendored just like the
CUDA ones. Despite being HIP, these are actually generic because it onyl
uses clang builtins and the `gpuintrin` shims.

On POSIX systems, traditionally the lldb Python module is in

On Windows, we've always had the Python module in lib\site-packages.
Change the behavior on POSIX to match the Windows behavior, and put the
lldb Python module in lib/site-packages.

[RISCV] Pass structs containing riscv_rvv_vector_bits types using vector registers. (#203601)
The ABI for this isn't documented. The riscv_rvv_vector_bits feature was
copied from aarch_sve_vector_bits which passes the types in vector
registers. At the time I implemented RISC-V I didn't think about struct
arguments so no ABI support was added.
I think it makes sense to pass structs of these types in vector
registers similar to the vls_cc ABI. We already do use vector registers
for these types when the vls_cc ABI is enabled for a function(unclear if
that was intentional), but we should do it unconditionally.
I will work with gcc maintainers to see if they can do the same. In
practice, there probably isn't much compiler mixing with these types.
This patch was heavily assisted by AI, but I've reviewed it and the
changes seem reasonable to me.

[CodeGen] Rename prologpeilog to prolog-epilog (#207870)
This is primarily to ensure consistenct with the new pass manager where
the name of the pass is already prolog-epilog, which is more consistent
with our existing naming scheme. This is necessary to be able to run
existing llc invocations that explicitly specify prolog-epilog under the
NewPM automatically.

CI: move libclang python bindings tests to main CI (#201677)
This removes the separate python bindings CI, which run on the GitHub
free runners and take more than one hour to build libclang.
The tests are executed instead in the monolithic pipelines, whenever
clang would be tested.
That only tests whatever python version we set up for that pipeline.
This is fine in terms of resources because all the dependencies are
built anyway, and the tests themselves take less than one second to run
on the free runners.

Fix APInt::concat for zero-width operands (#207475)
APInt::concat triggered undefined behavior (invalid shift exponent) when
concatenating a zero-width operand with a 64-bit operand on the fast
path (combined width <= 64). For example, `I0.concat(I64)` resulted in
`U.VAL << 64`, which is UB.
Fix by checking for zero-width operands early and returning the other
operand. Added regression tests to `APIntTest.cpp`.

[Tooling] Preserve backslashes in POSIX source paths (#207499)
On POSIX, backslashes are valid filename characters. Avoid converting
them to slashes when computing absolute source paths in LibTooling,
since doing so changes paths such as `a\b.cc` into `a/b.cc`.

[LFI][X86] Add X86 LFI target and system instruction rewrites (#189569)
This PR introduces an x86-64 backend for Lightweight Fault Isolation
(LFI), similar to the one being developed for AArch64. LFI is a
compiler-based mechanism that enables efficient in-process sandboxing.
See the RFC from last fall for details.
This PR adds the `x86_64_lfi` target (similar to `aarch64_lfi`), sets up
reserved registers, and implements some initial rewrites for system
instructions (system calls and TLS accesses). The rewrites are done at
the MC level, using the `MCLFIRewriter` infrastructure. I have updated
the documentation to describe the x86-64 sandboxing scheme and to list
rewrites that will be implemented in future PRs (to keep each individual
PR small).
For performance and compatibility reasons, the plan is currently to use
bundling for maintaining control-flow integrity in the sandbox, which
is not yet supported. For now we are setting up the rewrites without using
bundling, but we can also use a CFI mechanism based on shadow
stack+endbr in order to have something usable while bundling is
in progress.

Add dedicated assembler diagnostics for the RV32 GPR pair operands used
by
Zclsd compressed load/store pair instructions.
After the RISC-V asm parser started reporting multiple near-miss
reasons, these
operands still fell back to the generic "invalid operand for
instruction" note.
Give them explicit diagnostic types and messages so invalid register
pairs report
the expected pair constraints.

[RISCV][P-ext] Add codegen for packed absolute difference sum (#207314)
The pabdsumu/pabdsumau instructions compute the sum of absolute differences
of packed unsigned bytes; pabdsumau also accumulates into rd.
Add the llvm.riscv.pabdsumu and pabdsumau intrinsics. A single-GPR source is
selected directly to pabdsumu.b/pabdsumau.b with isel patterns. A 64-bit
GPRPair source on RV32 has no paired instruction, so it is split during
lowering into two v4i8 halves: reduce the low half (folding in rd when
accumulating), then accumulate the high half into that partial sum.
Cases with a target-illegal result are handled in ReplaceNodeResults:
RV64, i32 result: reduce at i64 and truncate (a 32-bit source is
zero-extended first).
RV32, i64 result: reduce each half with pabdsumu.b and combine the
partial sums with a widening add (waddu/waddau).

[libc] Improve Dir class safety, performance, and style (#207214)
Addressed issues in the Dir class identified during review:
* Safety: Added bounds and validation checks in Dir::read to prevent
out-of-bounds reads on corrupted input.
* Performance: Aligned the internal buffer to struct dirent to prevent
unaligned memory access, and increased the buffer size to 4096 to reduce
syscall overhead.
* Style: Replaced the system <dirent.h> include with a new proxy header
(struct_dirent.h) to avoid system dependencies, and fixed relative
includes.
* Refactoring: Moved platform-specific record length access to a
platform helper (platform_dir_reclen).
* CMake: Updated dependencies for the dir target.

Using INTERFACE libraries was proposed here:
https://github.com/llvm/llvm-project/pull/171610#discussion_r3122187957
Since such libraries can also propagate build options use this instead
of `target_compile_options`. Unfortunately this does not mean we can get
rid of `flang_module_target` because it also needs to set the module
output directory.

[LoongArch] Fix vpermi.w legalization with undef elements (#207751)
For the MaskSize==8 case, the code was comparing mask elements that
could be undef (-1). This could result in a miscompile (where -1 + 4 ==
3, which crosses from the high half to the low half) or the pattern not
matching (because -1 doesn't match the other mask element).
Fix this by explicitly handling undef elements in the code. If the high
half is undef, we can just ignore. If the low half is undef, we need to
use the value from the high half shifted down by 4. If neither are
undef, use the original check.

[AArch64][msvc] allow higher align than slot size in va_arg (#207591)
Fixes https://github.com/llvm/llvm-project/issues/207584
On aarch64 windows, an `__int128` argument is passed with alignment 16,
but was read with an alignment of 8. Based on the MSVC assembly and how
e.g. aarch64 darwin handles this, I think it's correct to set
`AllowHigherAlign = true`.

[X86][Windows] use `LowerWin64_INT128_TO_FP` for `u128` to `f128` conversion (#207285)
This change fixes an ABI issue where the signed conversion passes a

The signed case being correct is apparently due to a special
windows-specific path being chosen. The unsigned version bailed out too
early. So, I've changed `LowerUINT_TO_FP` to be more like
`LowerSINT_TO_FP`. In particular this moves the "Bail out when we don't
have native conversion instructions." down a bit, so that
`LowerWin64_INT128_TO_FP` is actually used.
I've then also added some testing for win64 SSE. I'm not sure if the
other target features are as relevant but I can add those too if
helpful.
This was found by running the `rust-lang/compiler-builtins` tests with a
build that includes https://github.com/llvm/llvm-project/pull/204887.

[RISCV][LLDB] Add RISC-V Architecture plugin for trap validation (#207675)
Add a minimal `RISC-V Architecture` plugin and implement
`IsValidTrapInstruction` for trap opcodes. The plugin recognizes riscv32
and riscv64 targets and validates 32-bit `EBREAK` and 16-bit `C.EBREAK`.
On RISC-V, `EBREAK` traps with the PC still pointing at the `EBREAK`
instruction. A plain continue resumes from that same PC and traps again.
This issue was found while trying to run the `TestBuiltinDebugTrap` test
case locally on a `RISC-V QEMU`.
Added a cpp unit test to verify the behaviour of
`IsValidTrapInstruction`. I've chosen to verify `EBREAK` on `riscv32`
and `C.EBREAK` on `riscv64` so that there is some coverage for both
targets.

[clang][AST] Qualify DeclRefExpr printing (#206041)
I updated DeclRefExpr printing so fully-qualified printing consistently
uses declaration ownership rather than only the written qualifier. This
also preserves existing behavior for local names and cleaned parameter
names.
The added tests cover both the direct expression printer behavior and
the original type-printing scenario that exposed the missing
qualification.

[AArch64] C1-Nano scheduler cleanup in preparation for SME [NFC] (#207738)
Change are in preparation for a forthcoming addition of SME to the
C1-Nano scheduling model. This is restructuring of the code which does
not involve the actual SME changes. By separating out these NFC changes
it will make review of the SME specific changes easier.
- Defined resource names to match the form now used in the C1-Ultra
scheduling model which has the throughput information on the end of the
name rather than in the middle:
C1NanoWrite_1c_1r_2ALU => C1NanoWrite_1c_2ALU_1rc
- Moved definitions so that they more closely match the order they are
defined in the C1-Nano SWOG. This make it easier to match entries in the
code to the tables in the SWOG.
These changes also make the C1-Nano scheduling model more closely match
the forms and layout used in the C1-Ultra scheduling model.

[Hexagon] Optimize sext + mul pattern for splatted scalar sext i16 (#206893)
Extend the existing vmpyh pattern to handle the case where one operand
of a v2i32 nsw mul is a splatted scalar sext i16 value. When the splat
is hoisted out of a loop, it arrives as assertsext v2i32, i16 in the DAG
rather than sext v2i16. The existing pattern did not match this form,
causing the multiply to expand to two scalar mpyi instructions.
Add a PatFrag assertsext_v2i32_i16 to match assertsext nodes of type
v2i32 extended from i16, and two new patterns (both operand orderings)
that recover the v2i16 using A2_combine_ll before feeding into
M2_vmpy2s_s0.

[clang] Fix constant-evaluator crash on array new with no size (#207730)
An array new-expression whose bound is neither specified nor deducible
from its initializer (for example `new int[]()`) is ill-formed and is
already diagnosed by Sema with `error: cannot determine allocated array
size from initializer`. However, the constant evaluator still tried to
evaluate the recovery expression. In
`PointerExprEvaluator::VisitCXXNewExpr`
the array size is unavailable (`E->getArraySize()` is `nullopt`), so the
allocation fell through to the scalar-new path, producing an array
`APValue` stored under a scalar type. Reading that object later asserted
in `Type::castAsArrayTypeUnsafe()` (`isa<ArrayType>(CanonicalType)`)
from
`CheckEvaluationResult`.
This patch detects an array new-expression whose size could not be
determined and bails out of constant evaluation.

We currently compute the cost of interleaved + strided ops as N *
scalar element memory ops, but on rv32 the scalar memory access will
be on an illegal type for 64 bit elements, even with zve64x. Prevent
it from overcosting by just using TCC_Basic.

[lldb][Linux] Show si_addr for SIGBUS signals (#207718)
The general rule is if si_addr is the same as the PC, we don't show it
because it doesn't add any new information.
SIGBUS signals are caused by an instruction trying to do something, but
si_addr is not the address of the instruction. It's some virtual
address, which is the important bit so add it to the description.
https://man7.org/linux/man-pages/man7/signal.7.html
> SIGBUS <...> Bus error (bad memory access)
Before:
```
* thread #1, name = 'test.o', stop reason = signal SIGBUS: illegal address
* frame #0: 0x0000aaaaaaaa0b80 test.o`main at test.c:42:13
```
After:
```
* thread #1, name = 'test.o', stop reason = signal SIGBUS: illegal address (fault address=0xfffff7ff6000)
* frame #0: 0x0000aaaaaaaa0b80 test.o`main at test.c:42:13
```
I am not adding test cases for this because:
* They would be architecture specific.
* Reliably generating BUS_OBJERR seems difficult.
* Signal reporting has good coverage as it is, so we know that
si_code/si_addr are handled correctly.

[LLE][LoopDistribution][LoopVersioning] Form LCSSA at Caller Invoking LoopVersioning Utility (#202296)
LoopVersioning utility `versionLoop()` expects the input form to be
LCSSA. However, passes like Loop distribution, Loop-load-elimination,
may invoke versioning with a non-LCSSA IR. Versioning updates exit-block
PHIs to handle both the original loop and the cloned loop. However, a
raw non-LCSSA use in the exit block (such as `switch i1 %C`) still
points to the original loop’s `%C`. On the cloned-loop path, control
reaches the exit block without executing the original `%C`, resulting in
error: `Instruction does not dominate all uses!`.
The fix is to form LCSSA at the caller pass.

[AArch64] llvm-mca C1-Ultra tests: SVE instructions added by SME when not streaming [NFC] (#207948)
In the C1-Ultra llvm-mca test, moves some instructions that were
incorrectly in the test file for "Instructions available with no SME but
will be sent to CME when in streaming SVE mode" into a file specifically
for instruction that are "SVE instructions added by SME and available
when not in Streaming SVE mode".
This is in preparation for forthcoming C1-Nano SME support to the
scheduling model that currently has no information about these
instruction due to lack of information in the C1-Nano SWOG.
This change is currently NFC because the C1-Ultra is still running the
the same tests, just from different test files.

[libc] Add inet_ntop (#204143)
The function converts from IPv4/6 addresses to their string forms. The
complication comes from the v6 part due to address compression and
v4-mapping.
The traditional implementation of this is to sprintf the address into a
temporary buffer. We cannot do that here due to the ban on calling other
entry points. Using the lower-level constructs is possible, but a
straight forward application of IntegerToString does not result in
particularly impressive performance: 50%-100% slower than what's in this
patch (and slower than glibc). It also doesn't make the code much
smaller as the majority of it is dedicated to v6 compression.
The IPv6 implementation uses a temporary buffer, but it also has a
fast-path which skips the buffer if its size is guaranteed to be
sufficient. The IPv4 implementation also has a fast path, but the
fallback here is to compute the precise length of the string instead
(the buffer option was slower and IPv4 makes it easier to compute the
precise length).
The v6 compression code is unrolled to make it easier to optimize. While
it is possible to write a single printing loop that handles all cases,
its branchiness does not make it amenable for optimization.
The resulting function is faster than its glibc counterpart, though the
exact ratio varies depending on the input:
- random IPv4: 15% faster
- random IPv6: 6% faster
- "::": 50% faster

[NFC][mlir][bufferization] Align alloc/memcpy/cast options hooks to the rest (#206966)
There are three hooks that have a different, more complicated API than
the other ones: allocationFn, memCpyFn, castFn. All three are called via
"helper" functions that check whether the hooks are set to call them and
fall back to default implementations otherwise.
Other hooks (e.g. unknownTypeConverterFn) in the bufferization options
have a different "API": they are always set to some default
implementation and can be overwritten by the user. This is a simpler API
overall and seems it can be universal.
Note for LLVM integration: BufferizationOptions::{createAlloc,
createMemCpy, createCast} functions are "replaced" with direct calls to
the underlying std::function objects. At any call-site that relied on
any of the removed APIs, a call to the respective hook should now be
used instead. The exception is the `allocationFn` hook which needs an
explicit "bufferAlignment" parameter. Beforehand, it was implicitly
taken from BufferizationOptions::bufferAlignment field, so a
non-functional migration path is to go from
`options.createAlloc(builder, loc, destType, value)` to
`options.allocationFn(builder, loc, destType, value,
options.bufferAlignment)`.

[libc] Implement if_nametoindex and if_indextoname (#206082)
This patch implements if_nametoindex and if_indextoname for Linux.
Both functions work by creating a temporary AF_UNIX socket and issuing
ioctl calls (SIOCGIFINDEX and SIOCGIFNAME, respectively).
The main implementation details:
- for if_nametoindex, I check that the interface name fits within
IF_NAMESIZE before issuing the ioctl
- for if_indextoname, if the kernel returns ENODEV for an unknown index,
I map it to ENXIO to comply with POSIX requirements
- added the definition of struct ifreq to support these operations.
Similar to the other net structure definitions, I'm using an anonymous
union to avoid #defining members.

[X86] Fix inline asm modifier printing across dialects (#204558)
X86AsmPrinter handles several inline asm operand modifiers differently
depending on whether the asm block uses AT&T or Intel syntax.
For `%a` and `%A`, the scalar/register operand path used AT&T
punctuation unconditionally. In Intel-dialect inline asm this could
print invalid forms such as `(rdi)` for an address operand or `*rdi` for
an indirect call operand.
For `%P`, `PrintAsmMemoryOperand` passed `"disp-only"` to both the Intel
and AT&T memory printers, but only the Intel path honored it for
global/symbol displacements with a base register. The AT&T path could
therefore print `g(%rdi)` even though `%P` requested displacement-only
output.
Make the affected X86 asm-printer paths dialect-aware/consistent:
- print Intel `%a` register operands as `[reg]`
- print Intel `%A` register operands without AT&T `*`
- make AT&T `%P` honor `"disp-only"` for global/symbol displacements,
matching the existing Intel behavior

[Clang] Renumber TokenKey enum values to close gap left by KEYNOZOS removal (#207906)
The previous commit (#207132) removed the unused KEYNOZOS flag
(0x4000000) but left a gap between KEYZOS (0x2000000) and KEYHLSL
(0x8000000). This patch renumbers the subsequent TokenKey values to
close the gap:
KEYHLSL: 0x8000000 -> 0x4000000
KEYFIXEDPOINT: 0x10000000 -> 0x8000000
KEYDEFERTS: 0x20000000 -> 0x10000000
KEYNOHLSL: 0x40000000 -> 0x20000000
The ~0x4000000u exclusion in KEYALL and the associated reserved-bit
comment are removed, since the renumbering eliminates the orphaned bit.
This is a follow-up to #207132, as suggested by @perry-ca.

[X86] Sync compiler-rt cpu subtypes and vendors with libgcc and refactor internal cpu type tables in LLVM (#171172)
This is a continuation of previous PR:
https://github.com/llvm/llvm-project/pull/168750
compiler-rt was synced with libgcc on ProcessorVendor and
ProcessorSubtype fields and so was llvm. Cpu type, subtype and vendor
entries in X86TargetParser.def were refactored to use ABI_VALUE.
LLVM doesn't set the ABI_VALUE for its enums -- clang now takes care of
that by reading the ABI_VALUE.
I've removed and added some comments to better explain what is going on.
While at it, I've added tests to check that right values are passed for
vendor, subtypes, types and features (the last ones weren't added in
feature sync PR: https://github.com/llvm/llvm-project/pull/168750)
Parts of the PR (test) have been realized using Claude Code

[libcxxabi] Don't enable -fvisibility=hidden on Windows (#207943)
This option is supported (and hence gets added by the
target_add_compile_flags_if_supported function) on Windows, but if using
dllexport, there's no point in using hidden visibility. (However if
building both static and shared libraries at the same time, it could be
beneficial to have hidden visibilty in the static libraries.)
In asserts enabled builds of Clang, building with -fvisibility=hidden
caused errors like this:
dllexport GlobalValue must have default or protected visibility
ptr @_ZTIv
[...]
fatal error: error in backend: Broken module found, compilation aborted!
Normally, combining -fvisibility=hidden with dllexport is not a problem,
but specifically for `__cxxabiv1:: __fundamental_type_info` it does make
Clang trigger an inconsistency, visible in asserts enabled builds of
Clang - see https://github.com/llvm/llvm-project/issues/207963.
This fixes Windows builds with Clang with asserts enabled, after

[AMDGPU] Select the high-half 16-bit packing idiom to v_lshl_or_b32 (#206058)
The (hi << 16) | z high-half packing idiom is not fused by the existing
(or (shl x, y), z) selection. By the time it reaches ISel the DAG
combiner has rewritten (ext i16) << 16 into bitcast(build_vector (i16
0), hi), so there is no shl node left to match and the build_vector and
or are selected separately.
Add ISel patterns that match the build_vector form directly. On the
non-real-true16 path the high-half source is a VGPR_32, so fold into
v_lshl_or_b32. On the real-true16 path the high-half source is a VGPR_16
and 16-bit ops are native, so OR it into the high half of the other
operand with v_or_b16 and assemble the result with a REG_SEQUENCE.

Reapply: [llvm-dwarfdump][LineCov 3/3] Add IR analysis for variable coverage (#207974)
Reapplies 5f4940ef. The original patch caused failures on buildbots due to
adding uses of functions defined in LLVMCore and LLVMIRReader without
adding those libraries to the dwarfdump link components.
Patch 3 of 3 to add to llvm-dwarfdump the ability to measure DWARF
coverage of local variables in terms of source lines, as discussed in
this RFC:
https://discourse.llvm.org/t/rfc-debug-info-coverage-tool-v2/83266
This patch adds an IR-level analysis in order to more accurately compute
the defined ranges for each variable. This avoids the problem of the
more naïve approach relying on source scopes, which overcounts as
coverable those lines where the variable is not yet defined (e.g. stack
variables).
The IR analysis requires IR to be provided to llvm-dwarfdump as a
separate `--variable-coverage-bitcode-file` argument (either textual IR
or bitcode; can be produced by various means e.g. `--save-temps
--emit-llvm`, `-ffat-lto-objects`,
[wllvm](https://github.com/travitch/whole-program-llvm)). The
recommended way to obtain a whole-program bitcode file is to use wllvm
as follows:
```sh
$ export LLVM_COMPILER=clang
$ CC=wllvm make # build as usual, but replace clang/clang++ with wllvm/wllvm++
$ extract-bc binfile # produces binfile.bc, which can be passed to llvm-dwarfdump
```

[SPIRV] Expand aggregate instructions with mutated-type uses (#206835)
This is a workaround for the problem in GH issue
https://github.com/llvm/llvm-project/issues/203586.
The problem is that we need to mutate aggregate-typed PHI nodes to
`i32`, however that means all incoming values need to have a matching
type, but we can't always easily mutate the incoming types to i32, as in
the case in the GH issue with a math intrinsic that returns a struct
by-value.
We do the same mutation for some other cases like `freeze`, the
workaround is the same.
The workaround is to expand the incoming values to a form that will also
be mutated to i32 so the types match. An example transformation is
below:
Before
```
...
bb1: ; preds = %entry
%0 = call { i64, i1 } @llvm.usub.with.overflow.i64(i64 %a, i64 %b)
br label %epilog
...
%2 = phi { i64, i1 } [ %1, %bb0 ], [ %0, %bb1 ]
```
After
```
...
bb1: ; preds = %entry
%0 = call { i64, i1 } @llvm.usub.with.overflow.i64(i64 %a, i64 %b)
%1 = extractvalue { i64, i1 } %0, 0
%2 = insertvalue { i64, i1 } poison, i64 %1, 0
%3 = extractvalue { i64, i1 } %0, 1
%4 = insertvalue { i64, i1 } %2, i1 %3, 1
br label %epilog
...
%10 = phi { i64, i1 } [ %9, %bb0 ], [ %4, %bb1 ]
```
`insertvalue` get replaced with a SPIR-V intrinsic later in the pass
which is also type-mutated, so the IR is correct:
```
...
bb1: ; preds = %entry
%0 = call { i64, i1 } @llvm.usub.with.overflow.i64(i64 %a, i64 %b)
call void @llvm.spv.value.md(metadata !0)
call void (...) @llvm.fake.use({ i64, i1 } %0)
%1 = extractvalue { i64, i1 } %0, 0
call void @llvm.spv.assign.type.i64(i64 %1, metadata i64 poison)
call void @llvm.spv.assign.type.i32(i32 undef, metadata { i64, i1 } poison)
%2 = call i32 (i32, i64, ...) @llvm.spv.insertv.i64(i32 undef, i64 %1, i32 0)
call void @llvm.spv.assign.type.i32(i32 %2, metadata { i64, i1 } poison)
%3 = extractvalue { i64, i1 } %0, 1
call void @llvm.spv.assign.type.i1(i1 %3, metadata i1 poison)
%4 = call i32 (i32, i1, ...) @llvm.spv.insertv.i1(i32 %2, i1 %3, i32 1)
call void @llvm.spv.assign.type.i32(i32 %4, metadata { i64, i1 } poison)
br label %epilog
...
%10 = phi i32 [ %9, %bb0 ], [ %4, %bb1 ]
```
This is the simplest change I could come up with, my other ideas were
much more complicated and/or risky.
This fix is important for us because this pattern comes up in libc's
implementation on FMA, so this is blocking SPIR-V libc support.

[SelectionDAG] Fold VECREDUCE_ADD of a constant BUILD_VECTOR (#207560)
This PR implements constant folding for ISD::VECREDUCE_ADD when the
input is a BUILD_VECTOR of integer constants. The fold computes the sum
at compile time using APInt arithmetic and returns a folded constant
scalar, instead of emitting real vector materialization and reduction
instructions for a value that's already known.
Folding is skipped if any element is undef or opaque, since the result
can't be assumed at compile time in that case.
Fixes #206743

[AMDGPU] Stop adding implicit def of superreg in copyPhysReg (#125255)
Previously when copyPhysReg expanded a COPY into multiple MOV
instructions it added an implicit def of the destination superreg to the
first MOV. Removing these does not cause any liveness verification
problems and still passes Vulkan CTS for correctness testing.

[clang][X86] Emit AVX level mismatch psABI warnings on function definitions (#199091)
Emit -WpsABI for x86_64 function definitions whose return type or
parameter type uses a vector wider than 128 bits without the required
ABI feature enabled. 256-bit vectors require avx, and 512-bit vectors
require avx512f.
Previously this diagnostic was only emitted at call sites, so
definitions with wide vector signatures could be introduced without a
warning until they were called. Use the function feature map so
attribute(target("avx/avx512f")) definitions are accepted, and emit no
warnings for prototype-only declarations.

[libc][stdfix] Fix idiv* doc table, rename idivfx test helpers and remove duplicate bitsuk source (#206729)
Two small cleanups in libc/src/stdfix.
1. `idiv*` in `stdfix.rst` was marked as implemented for all 12 type
variants but only the 8 non-short width variants (ur, r, ulr, lr, uk, k,
ulk, lk) exist in the directory and are built. Updated the table to
match.
2. Removed `bitusk.cpp` which is an orphaned duplicate of `bitsuk.cpp`
with a typo in the file name. It isn't referenced in the CMakeLists.txt
and has no corresponding .h file.
3. Rename the idivfx test header and helpers.

[libc++][ThreadSafety] Add thread safety annotations for variadic std::scoped_lock (#204462)
The thread safety annotations on std::scoped_lock were previously only
applied to the empty and single-mutex specializations. The general
variadic specialization carried no annotations, so -Wthread-safety
considered none of the mutexes held inside a multi-mutex scoped_lock
block and reported the guarded data accessed there as unprotected.
Now that Clang supports pack expansion inside thread safety attributes
(landed for Clang 21), annotate the variadic scoped_lock with
acquire_capability/requires_capability on its constructors,
release_capability on its destructor, and scoped_lockable on the class.
Fixes #42000.

[AArch64][LV] Cost low-VF interleaved access (#205844)
Adds a case to getInterleavedMemoryOpCost to cost scalable interleaved
memory accesses where the interleave factor is larger than the VF.
Previously for these cases, memory operations would be costed as
individual gathers and scatters, which may result in the LoopVectorizer
choosing a wider VF than necessary.
This changes proposes an alternative approach of using a contiguous
load/store of the interleaved vector followed by shuffles to get
the elements into place.

Some dependencies have big knock-on effects and to the benefit of

divides the `MODULE.bazel` file into two sections where one contains
known sensitive dependencies that should only be bumped as needed and
the second are flex dependencies that can freely be updated with minimal
impact to external consumers.

[clang][Modules] Support ODR merging of `UsingEnumDecl` (#207071)
Fixes https://github.com/llvm/llvm-project/issues/207066.
`UsingEnumDecl` (representing C++20 `using enum` declarations)
was not handled in `ASTContext::isSameEntity`.
Consequently, identical class definitions containing
a `using enum` statement failed to merge, resulting in spurious ODR
mismatch errors such as: `error: 'MyStruct::MyEnum' from module
'ModuleB' is not present in definition of 'MyStruct' in module
'ModuleA'`.
This patch implements merging support for `UsingEnumDecl` in
`ASTContext::isSameEntity` by comparing the nested-name-specifier
qualifiers and the underlying `EnumDecl` target.

As far as I can see `wasi-libc` does not currently export the dedicated
libcalls, so I went with a custom expansion. It emits more code, but
will work without any linker errors etc.
The `long double` type is actually `f128` for webassembly, so at least
the libcalls should work.

[llvm] Support invariant.load on readonly intrinsics (#205916)
Update passes and analyses that look at invariant.load (ex. MemorySSA)
to also consider the possibility that `!invariant.load` may be present
on intrinsic calls.
Updates the verifier to indicate that `!invariant.load` is only legal
for loads and readonly intrinsics (and moves the definition of the
metadata out of the definition of `load`).
This has not been extended to arbitrary function calls since it's less
clear what the semantics of !invariant.load on them would be.
Furthermore, extension to read/write intrinsics like memcpy() is planned
as a followup.
This PR also deletes tests that were pre-committed in
https://github.com/llvm/llvm-project/pull/205894 but that become invalid
with the verifier changes in this PR
AI disclosure: I've reviewed the code but all the actual generation was
done by AI.

[flang][OpenMP][NFC] Share SetSymbolDSA between semantics and lowering (#207826)
Move the DSA helper from the private OmpAttributeVisitor::SetSymbolDSA
into the public openmp-dsa header next to GetSymbolDSA, and share the
DSA flag set through a single GetDataSharingAttributeFlags().
This lets an upcoming metadirective lowering change reuse the helper to
set the predetermined DSA of the loop induction variables of a selected
variant. A loop-associated variant is resolved during lowering, so the
usual semantic DSA resolution never runs on its loop nest and lowering
must set those flags itself.
Assisted with Copilot.

If a type is declared as a `class` or a `struct` is part of the mangled
name in the Microsoft ABI. This is also reflected in the demangled name.
There, it shows up before the qualified name. For example, you could
have `class ns1::ns2::MyClass`. It will show up like this in return
types and function/template arguments.
This adds a check in `CPlusPlusNameParser::ParseFullNameImpl` for these
cases.

[mlir][acc][flang] Add type sizing utilities (#208074)
Add a general acc utility for computing the size and alignment of a
type. It works for simple scalar types as well as nested and aggregate
types like arrays, tuples, and structures.
Because some types come from other dialects, the utility can hand those
off to a specialized helper that understands them. This lets sizing work
seamlessly even for mixed types, such as an aggregate whose members come
from a different dialect.
Add a Fortran-specific helper so Fortran types are sized correctly,
falling back to the general utility for everything else.
Include unit tests covering a range of scenarios, including scalars,
arrays, aggregates, and mixed-dialect types.

Reverts llvm/llvm-project#192142
Now that https://github.com/llvm/llvm-project/pull/205113 has landed, we
will not inline functions with incompatible target features, even if the
callee is marked `alwaysinline`, so we can promote calls to such
functions while also removing the extra complexity from ICP.

[lldb] Give Wasm stack frames a synthetic call frame address (#208061)
UnwindWasm reported a call frame address of zero for every Wasm frame.
StackID orders frames by their CFA, assuming the stack grows downward so
that a younger frame compares below its caller. With every CFA equal to
zero that ordering collapsed, and CompareCurrentFrameToStartFrame
treated a step into a function as a step out, which silently disabled
step-in avoid-regexp and confused other thread plans.
WebAssembly keeps its call stack inside the engine and exposes no
linear-memory frame address, so synthesize a CFA from each frame's
distance to the outermost frame. That distance is invariant as frames
are pushed and popped above it, so a given frame keeps a stable, ordered
CFA across steps.

[ARM] Don't try to emit AEABI libcalls for non-AEABI targets (#207813)
PR #172672 added ARMTargetLowering::LowerAEABIUnalignedLoad/Store which
lowers some of the unaligned i32/i64 stores to
__aeabi_u{read,write}{4,8}. The libcall is emitted unconditionally, with
no check whether the target environment actually has these AEABI
helpers.
We don't have it for Apple/MachO which leads to a compiler crash.

Reland "Compute GUIDs once and store in metadata" (#184065) (#201849)
This reverts #201194, thus relanding @orodley's PR #184065 (and
#200323):
> This allows us to keep GUIDs consistent across compilation phases
which may change the name or linkage type.
> See
https://discourse.llvm.org/t/rfc-keep-globalvalue-guids-stable/84801
The CFI issues that triggered the original revert are fixed by #201370,
together with the addressing of the TODOs in `LowerTypeTests.cpp` left
in the latter. The [graphite
diff](https://app.graphite.com/github/pr/llvm/llvm-project/201849/Reland-%23184065)
between this change's V1 and V2 shows what's been added:
- the `TODO`s from #201370 are done
- in LowerTypeTests.cpp, passing `!guid` when creating a new declaration
and when converting a definition to a declaration.
- `llvm/test/Transforms/LowerTypeTests/export-icall.ll` tests also the
above def->decl conversion
- removed
`test/Analysis/CtxProfAnalysis/flatten-prethinlink-requires-guid-metadata.ll`
introduced in #194383 (this was between the revert and this PR), as now
the general expectation is that GUID assignment happens appropriately
and all passes use `getGUID`, so there's no reason for `CtxProfAnalysis`
to do something different.
Currently, we reassign GUIDs when CFI promotes internal linkage symbols,
which is counter to the goal of the RFC. This is addressed in PR
#203171. The reason for this split fix can be explained on
`compiler-rt/test/cfi/icall/wrong-signature-mixed-lto.c`. Here, a module
with the exact same source path is compiled twice, under different
conditional compilation, to produce 2 objects. Each object defines an
internal linkage symbol with the same name (this is
`install_trap_loop_detection` from
`compiler-rt/test/cfi/trap_loop_signal_handler.inc` which is
`-include`\-d by both - see how `%clang_cfi` is defined). The ThinLTO
GUID of this symbol will be the same. Its name won't be - because CFI
promotes it and renames it using a hash that is based on the IR Module
content (rather than the source path). During thinlink,
`LTO::addThinLTO`will mark each of the 2 exported symbols as prevailing
in their corresponding modules. But that is done by associating their
GUID to the module. So whichever comes last wins. The other symbol will
be marked available externally and its body DCEd later in backend. But
each module will refer to its copy of `install_trap_loop_detection`, and
so we end up with a linker error.
As mentioned, the fix is in PR #203171, and this relanding PR just
maintains the existing ThinLTO behavior by rewriting the GUIDs. Since we
haven't yet leveraged the GUID mechanics for e.g. simplifying PGO, this
aspect of this change is essentially NFC.

[lldb] Push ExpressionEvaluation policy and remove identity check fallbacks (#195775)
Push `PolicyStack::Get().PushPublicStateRunningExpression()` at all
three expression evaluation entry points
(`LLVMUserExpression::DoExecute`, `FunctionCaller::ExecuteFunction`,
`IRInterpreter`). This policy sets `can_run_breakpoint_actions=false`,
preventing recursive breakpoint callback execution during expression
eval.
Push `PolicyStack::Get().PushPrivateState()` unconditionally for all
PSTs in `RunPrivateStateThread` (not just overrides), giving every PST
the private view while keeping frame providers and recognizers enabled
for normal stop processing. Override PSTs use
`PushPrivateStateRunningExpression()` which additionally disables
providers and recognizers.
With all PSTs and expression eval sites now covered by the policy,
remove all host thread identity check fallbacks:
- `CurrentThreadPosesAsPrivateStateThread()` in `Process::GetState()`
- `CurrentThreadIsPrivateStateThread()` in `Target::GetAPIMutex()`
- `IsOnThread()` in `PrivateStateThread::GetRunLock()`
- `CurrentThreadPosesAsPrivateStateThread()` in
`SelectMostRelevantFrame()`
- `IsRunningExpression()` in `StopInfoBreakpoint::PerformAction()`
`SelectMostRelevantFrame` now checks `!can_run_frame_recognizers`
instead of `View::Private`, so recognizers run during normal PST stop
processing but are skipped during expression evaluation.

[flang][NFC] Remove unnecessary #include directives across flang (#207640)
Audit of every #include directive in flang/lib/ and
flang/include/flang/:
- Remove 423 #include directives (293 from lib/ translation units, 23
from lib-private headers, 107 from public headers) that are not needed:
no entity declared by the removed header is used - directly or in any
conditional-compilation branch (Windows, macOS, ARM/PowerPC,
REAL(16)/REAL(2) configuration macros) - in the including file, and for
headers no consumer in flang/lib, flang/tools, flang/unittests, or
flang-rt relies on the include as a re-export. Load-bearing includes
were examined and retained: textual .inc/.def expansions, tablegen
pass-header declaration/definition pairings, dialect headers carrying
generated-op interface dependencies, config-macro providers (e.g.
float128.h ahead of matmul-instances.inc guards), and ADL formatting
machinery (Evaluate/formatting.h).
- Add 5 missing direct #includes in lib translation units that used
entities only via now-removed transitive includes, and drop one
vestigial 'using namespace Fortran::runtime;' whose declaring header no
longer arrives transitively (nothing namespace-qualified from it was
used), per the include rules in flang/docs/C++style.md.

[flang][TargetRewrite] Keep argument attributes consistent after ABI arg shift (#208124)
When target-rewrite expands an argument into several arguments
(for example splitting a complex value into two scalars),
the arguments after it shift to the right.
Argument attributes were only moved for a shift introduced
by result lowering, so an attribute on a later argument
(e.g. fir.host_assoc) could stay on its old index and end up
on an unrelated argument. Remap every saved argument
attribute to the new index of its argument.
This is a consistency fix and may not cause a miscompile today.

[Hexagon] Disable restore stubs when ShadowCallStack is active (#206302)
The returning restore stubs (e.g.
__restore_r16_through_r17_and_deallocframe) perform deallocframe+jumpr
r31 internally, returning via the on-stack return address. This is
incompatible with ShadowCallStack, which must restore r31 from the
shadow stack before returning.
Fix by having useRestoreFunction() return false when the ShadowCallStack
attribute is present, forcing inline callee-saved restores so the SCS
epilogue is properly emitted.

This is a repeat of d48eb719d240 ("[NFC][ELF] Don't reimplement addReloc
in GotSection::addConstant") but for MipsGotSection. Unfortunately,
9fb61d972213 ("[NFCI][ELF][Mips] Refactor MipsGotSection to avoid
explicit writes (#178561)") was put up for review before, and was landed
after, that commit, and I did not think to update it, so it ended up
copying the old GotSection code. Although there's no motivation to
support CHERI in this code (even though CHERI-MIPS existed it never used
the highly-specialised MipsGotSection to hold capabilities), it's still
better to use our own abstractions, and to be consistent.

[CIR][CUDA] Support built-in CUDA surface type (#196079)
Related: #179278
This patch adds initial support for CUDA built-in surface types in CIR
for device-side compilation.
CUDA surface references are lowered to the NVPTX device-handle
representation (`i64`), matching existing Clang CodeGen behavior.
Changes
* Add `getCUDADeviceBuiltinSurfaceDeviceType()` target hook to
`TargetCIRGenInfo`
* Implement NVPTX surface lowering in `NVPTXTargetCIRGenInfo`
* Handle CUDA built-in surface types in `CIRGenTypes::convertType`
* Add CIR CUDA test coverage for device-side surface lowering
Notes
* This patch only implements device-side surface type lowering support
* Texture types remain unsupported
* TBAA handling for surface/texture types is left for follow-up work

[BPF] Return small aggregates directly in registers (#206876)
Previously the BPF ABI always returned aggregate (struct/union) types
indirectly through an sret pointer, regardless of size. This is
inconsistent with how classifyArgumentType() already passes small
aggregates: arguments up to 128 bits are coerced into one or two 64-bit
registers, while only larger aggregates use an indirect reference.
Make classifyReturnType() mirror that convention by factoring the shared
aggregate handling into a classifyAggregateType() helper used by both:
- empty aggregates (0 bits) are ignored;
- aggregates up to 64 bits are returned directly, coerced to an integer
of the padded size;
- aggregates of 65..128 bits are returned directly as [2 x i64];
- aggregates larger than 128 bits are returned indirectly via sret.
This keeps each returned value within the backend's two-register return
convention and avoids an unnecessary memory round-trip for small
structs.
This also aligns BPF with the general-purpose C ABIs of other targets:
both x86-64 (System V, RAX:RDX) and AArch64 (AAPCS64, X0:X1) return
aggregates up to 16 bytes in a pair of registers and only fall back to
an indirect sret pointer for larger ones.

[clang-tidy] Fix AllowImplicitlyDeletedCopyOrMove missing-move false positive (#207586)
The documentation for `cppcoreguidelines-special-member-functions` says
that `AllowImplicitlyDeletedCopyOrMove` suppresses diagnostics for
classes which implicitly delete copy or move operations.
In practice, the move operations are missing because the user-declared
destructor prevents their implicit declaration. This commit suppresses
that missing-move diagnostic when both copy operations are implicitly
deleted and no move operation is user-declared.

[LoopInterchange] Fix crash when dbg_value exists right after PHI (#208147)
When enabling reduction2mem with `-loop-interchange-reduction-to-mem`
and the input IR contains `dbg_value`s immediately after a certain PHI
node, assertion failure could be triggered due to the insertion position
of newly created PHI node. This patch fixes the issue by changing
IRBuilder ctor to be called. TBH, I'm not entirely sure what the
difference is between `IRBuilder::IRBuilder(Instruction *)` and
`IRBuilder::IRBuilder(BasicBlock *, BasicBlock::iterator)`, but judging
from the generated code, the behavior with this patch seems reasonable.

[AssumptionCache] Deduplicate affected values in removeAffectedValues (#205441)
removeAffectedValues can encounter duplicate entries in the Affected
list when a separate_storage bundle uses the same pointer for both
arguments (e.g. "separate_storage"(ptr %p, ptr %p)). The duplicate
entries share both the same value and the same bundle index. The first
iteration handles the value completely and may erase the AffectedValues
entry, causing the second iteration to fail the assertion.
This patch deduplicates entries in removeAffectedValues by (Value *,
Index) pair, matching the deduplication already done in
updateAffectedValues. This also fixes the ExpectedMatches counting in
the debug logic added by #205275, which otherwise miscounts when
duplicates are present.
Fixes #205378.

[VectorCombine] Fold concat(binop(a,c), binop(b,d)) -> binop(concat(a,b), concat(c,d)) for i1 vectors (#206087)
Fixes #205707
`VectorCombine::foldShuffleOfBinops` rewrites `shuffle(binop(a,c),
binop(b,d))` into `binop(shuffle(a,b), shuffle(c,d))` but only when the
new form is strictly cheaper. For concat shuffles of i1 vectors, both
forms have equal cost, so the transform was silently rejected.
This fix allows the equal-cost transform when both binops are single-use
`BinaryOperators` (not icmps, to avoid widening narrow AVX-512
comparisons), canonicalising the IR to a wider binop.
The motivating case is AVX-512 mask operations: `NOT(concat(XOR(a,c),
XOR(b,d)))` becomes `NOT(XOR(concat(a,b), concat(c,d)))`, which the
backend naturally selects as `kxnorq`, reducing `kxord + kxord +
kunpckdq + knotq` (4 instructions) to `kunpckdq + kunpckdq + kxnorq` (3
instructions).

[SDAG][X86] Support shrinking target-independent nodes (#206721)
X86 generally tries to shrink operations to work on smaller vector sizes
if possible. This happens in
SimplifyDemandedVectorEltsForTargetNode() for target-specific opcodes,
but it's currently not possible to do this for generic opcodes.
This introduces a getPreferredShrunkVectorSize() TLI hook to allow
shrinking generic ops based on demanded elements.
The primary motivation for this is to avoid regressions due to
https://github.com/llvm/llvm-project/pull/188489, which uplifts a
previously x86-specific node to become target-independent.
This PR enables the shrinking for fsub and fmul as examples.
Unfortunately, for many other ops we get various regressions, mostly
because horizontal operations are no longer formed.

[HashRecognize] Make `LHSAux` null if it is dead (#207231)
HashRecognize detects big-endian CRC loops with auxiliary data where the
bitwidth of `LHS` exceeds that of `LHSAux`. However, in this case,
`LHSAux` is zero-extended for the most significant bit check in each
iteration, and as such is effectively dead. Later optimization may even
miscompile in this case: for example, in the included
`crc16.be.tc8.zext.data` and `crc16.be.tc8.misalign` test cases,
`optimizeCRCLoop` emits `lshr i8 %crc.data.indexer, 8`, thereby creating
poison.
Since `LHSAux` is dead in this case, the user should receive a null
`LHSAux` instead.

[SelectionDAG][AMDGPU] Preserve known bits for demoted sret pointers (#203468)
AMDGPU marks sret pointers with high-zero known bits so stores can be
folded into MUBUF base+offset addressing. Explicit sret arguments keep
this information through an AssertZext, but implicit sret lowering
passes the hidden return pointer through `DemoteRegister` as a
`CopyToReg/CopyFromReg` pair, where the fact is not visible to
SelectionDAG known-bits queries.
Add a `TargetLowering` hook for sret pointer known bits and use a shared
helper to materialize those bits as an `AssertZext` for both explicit
and demoted sret pointers.
Validated with llvm-test-depends, the AMDGPU function-returns test, and
the full llvm/test/CodeGen suite.

[VPlan] Forbid CSE'ing writes (NFC) (#207443)
CSE'ing two identical writes does not consider the fact that there could
be another write that writes an aliasing memory location. Fix the
potential miscompile. Note that there is currently no miscompile, as we
never remove a write, but the patch has the benefit of not processing
writes unnecessarily.

[AArch64] Increase the relative cost of vector i64 multiply on Neoverse V3ae. (#207723)
The throughput of vector nxv2i64 multiplies on neoverse v3ae is 1/2, compared
to the throughput of 2 for integer multiplies. This large difference can mean
it is more profitable than normal to use scalar loops as opposed to vectorization.
This adds a subtarget feature that increases the cost multiple by 4 for 64bit
vector multiplies for specific CPUs. The cost model of llvm does not mean that
we can model throughputs correctly, but this should help. The same feature is
added to N2 as it has a similar difference between vector and scalar multiply
cost throughputs.

[flang][Lower] Add alternative real expression lowering (#207371)
This is opt-in by an engineering option and disabled by default.
In section 10.1.5.2.4 of the 2023 Fortran standard "Evaluation of
numerical intrinsic operations", the standard explicitly allows
alternate mathematically equivalent lowerings. For example the source
expression X + Y + Z could be evaluated (X + Y) + Z, X + (Y + Z) or even
(X + Z) + Y, etc.
The open source benchmark SNBone shows significantly better results with
classic flang because classic flang emits real arithmetic expressions in
a different order. In the case of this benchmark it reduces dependency
depth for instructions issued to the vector unit, allowing for more of
the arithmetic to be parallelised over multiple vector execution units
in the ALU.
The lowering added by this patch tries to mimic the way classic flang
orders instructions for these expressions. I did not read any classic
flang source when writing this patch. There is still a notable
difference in that classic flang uses FMA intrinsics whereas LLVM Flang
relies on the rest of the pipeline to introduce FMA when it is safe to
do so.
This is a much less aggressive optimisation than simply enabling reassoc
in the fast-math flags because it does not allow reassociation between
Fortran language statements. This is why I implemented it in lowering.
The new option enables an experimental lowering path for scalar real
top-level addition chains. When enabled with
-enable-split-sum-expression-tree-lowering, eligible sums are split
after the first two terms and rebuilt as a right-associated tail plus
head. This lets the independent tail terms be evaluated before the
assignment-related head, giving the backend a different expression tree
while leaving the default lowering unchanged.
The transform is deliberately narrow. It only applies to scalar real RHS
expressions in assignments and rejects cases with vector subscripts,
parentheses, subtraction, procedure references, or volatile/asynchronous
symbols on either side of the assignment. Subtraction is left out
because the split would need to carry signed terms; division stays
within an individual additive term and does not change the top-level
chain.
In testing I have found some tests in the Fujitsu test suite miscompare
due to small changes in floating point rounding. There are no failures
or regressions in SPEC2017 or SPEC2026. I think it would be legal
according to the Fortran standard to enable this by default, but I am
not proposing that here, and will not consider it until after the LLVM
release branch point.

This patch adds a few missing opcodes for arithmetic+CB(N)Z clustering.
Most of them complement an already existing rr/rs variant for
pre/post-RA coverage. The only one which is completely new is ORN which
I think can be reasonably expected to behave similarly on AArch64
targets.

[CodeGenPrepare] Cache known-live PHIs when deleting dead PHI chains (#207191)
This patch fixes a compile-time issue in CodeGenPrepare for huge
functions.
`DeleteDeadPHIs` may repeatedly prove overlapping PHI chains non-dead.
For very large functions, many PHIs can share the same non-dead def-use
suffix, causing the same suffix to be scanned many times.
Add an `KnownNonDeadPHIs` cache to `RecursivelyDeleteDeadPHINode`
and `DeleteDeadPHIs`. When a chain is proven non-dead, visited PHIs are
recorded so later queries can stop once they reach one of them.
This reduces the pathological CodeGenPrepare case from ~30mins to ~30s.

[Clang] Fix missing vtable for `dynamic_cast<FinalClass &>(*this)` in a function template (#207349)
This is a follow-up to #202594, which fixed a pointer cast, but not
a reference cast. Surprisingly, `CXXDynamicCastExpr::getType()`
for a reference cast is a `RecordType` and not a `ReferenceType`.
How this happens:
In `Sema::BuildCXXNamedCast`, a `CastOperation Op` variable
is constructed. The `CastOperation` constructor initializes
`ResultType(destType.getNonLValueExprType(S.Context))`
where `QualType::getNonLValueExprType` turns a `ReferenceType` into
a `RecordType`. `Sema::BuildCXXNamedCast` then passes `Op.ResultType`
to `CXXDynamicCastExpr::Create`.

[VPlan] Pull out reverses and splice.lefts from elementwise operations (#199234)
InstCombine pulls reverses up and out of operations, e.g.
`binop(reverse(x), reverse(y)) -> reverse(binop(x,y))`. This reduces the
overall number of reverses, and also allows the `reverse(reverse(x))`
combine to kick in much more.
This implements the same canonicalization in VPlan which allows for more
vectorization due to cost model improvements, and generally handles more
cases when there's predication involved.
If we have a reversed load and reversed store whose stores are now
eliminated, we will be left with just two reversed masks on the load and
store. But with EVL tail folding this will leave behind a
`splice.right(ops(splice.left(...)))` pair on the value from memory.
InstCombine can fold away a pair of `vp.reverse(ops(vp.reverse(...)))`,
but it can't fold a pair of splices. So to prevent regressions we also
have to pull splice.lefts like `ops(splice.left(poison, x, evl)) ->
splice.left(poison, ops(x), evl)`. The `splice.right(splice.left(x)) ->
x` VPlan transform will then kick in and remove it. We don't need to
pull splice.rights since they are only emitted at stores.

[InstCombine] Fold zext(sub(0, trunc(X))) to and(sub(0, X), mask) (#207564)
Problem: vector rotate and funnel shift fails to fold for vectors > 16
bytes on AVX-512. This is because of the `trunc` and `zext`
instructions.
Example:
```llvm
define dso_local <8 x i64> @baz(<8 x i64> %0, <8 x i64> %1) local_unnamed_addr {
Entry:
%2 = trunc <8 x i64> %1 to <8 x i6>
%3 = sub <8 x i6> zeroinitializer, %2
%4 = zext <8 x i6> %3 to <8 x i64>
%5 = shl <8 x i64> %0, %4
%6 = and <8 x i64> %1, splat (i64 63)
%7 = lshr <8 x i64> %0, %6
%8 = or <8 x i64> %5, %7
ret <8 x i64> %8
}
```
Solution; Canonicalize the transformation `zext(sub(0, trunc(X))) ->
and(sub(0, X), mask)` for scalars and vectors.
Closes #165306

[DFAJumpThreading] Propagate DebugLocs to branches in select unfolding (#205851)
When DFAJumpThreading replaces a select with control flow, it generates
new blocks, new branches in those blocks, and potentially replaces the
branch in an existing block. Prior to this patch, none of these branches
were assigned debug locations; this patch replaces them as follows:
For the case where we generate two new blocks between the select block
and use block, and use a PHI of those blocks to replace the select, we
use the select's debug location for the branch instructions, since they
are doing the work of the select.
For the case where we generate one new block and replace the
unconditional branch from the select block with a conditional branch to
the new block and the use block, we treat the new branches as replacing
both the select and the original branch, so each branch takes the merged
location of the original select+br.
This patch also ensures that when we create a new path which would end
with a switch statement, such that the switch statement can be safely
replaced with an unconditional branch, we propagate the switch's debug
location to the replacing unconditional branch.

[libc] Add a proxy header for sa_family_t (#207736)
This patch adds `hdr/types/sa_family_t.h` and updates socket tests and
helpers to use it instead of directly including `<sys/socket.h>` or
`include/llvm-libc-types/sa_family_t.h`.
The patch also adds a couple of includes of `hdr/types/socklen_t.h` for
files that are using the type, but not including it directly.

[Debugify] Simplify debugify for locations (#207374)
This patch attempts to improve the performance of debugify for
locations, by relying on coverage tracking to replace most of the
functionality provided via the DILocations map, in exchange for losing
the ability to distinguish between "dropped" and "not-generated" bugs,
and requiring coverage tracking to determine when new bugs appear in a
pass instead of reporting the same bug repeatedly across passes.
This patch is not without cost; the justifications for using it are
that:
- Debugify locations is incredibly expensive; on a local build, without
using any coverage-tracking, this patch takes the build time for sqlite3
down from ~15 minutes to ~10 seconds.
- The difference between "dropped" and "not-generated" is a minor detail
of a bug - besides helping to determine the cause of the bug, which
origin-tracking can do with more accuracy, there's no fundamental
difference in the correctness of either. Furthermore, almost no
"dropped" bugs appear in the compiler anymore (since the debug location
coverage tracker bot has been online).
- Requiring coverage tracking to prevent repeated bugs is a loss, but
coverage tracking is not a very expensive feature to enable compared to
using debugify itself, and the only public automated tests that use
debugify already enable coverage tracking.

[clang][ItaniumMangle] Fix mangling of lambdas in default member initializers of local classes (#206740)
Lambdas appearing in default member initializers of members of local
classes were previously mangled as if they belonged only to the class
scope, ignoring the enclosing function-local context.
This caused different (but same-named) local classes to produce
identical closure type mangling and corresponding RTTI/IR collisions.
Consider the following example:
```
void foo() {
{
struct T {
std::function<void()> a = [](){ std::cout << "a"; };
} t;
t.a();
}
{
struct T {
std::function<void()> a = [](){ std::cout << "b"; };
} t;
t.a();
}
}
```
The expected output is `ab` (and GCC-compiled code behaves accordingly),
while clang previously printed `bb` because the first `T::a` definition
is overridden by the second one due to the missing `<local-name>`
encoding and discriminator required to distinguish the two local `T`
definitions.

[X86] Add vXi64 MULHU/MULHS lowering, keeping full-width products scalar (#206983)
Based on the discussion in the PR #169819.
This lands the unsigned (`MULHU`) and signed (`MULHS`)
`vXi64` high-multiply lowering, plus a guard so full 128-bit products
stay scalar.
### What this does
1. **Lower `ISD::MULHU` for `v4i64`/`v8i64`** via `forceExpandMultiply`
(a `vpmuludq` schoolbook), as in #169819.
2. **Lower `ISD::MULHS` for `v4i64`/`v8i64`, gated on AVX512DQ.** The
signed low multiply is `vpmullq`, so `MULHS` is only marked `Custom`
when DQ (and VL for `v4i64`) is available.
3. **Guard the full-width-product case.** When the *low* half of the
product is also used (a `wyhash`-style `lo ^ hi`), vectorizing just the
high half is redundant with the low half's wide multiply. So, this guard
let a single scalar multiply per lane yield both halves, likewise the
unpatched target already did.
This is done by marking `UMUL_LOHI`/`SMUL_LOHI` `v4i64`/`v8i64` `Custom`
(unrolled), which lets the existing DAGCombiner check decline to narrow
`trunc(srl(mul(ext,ext)))` to `MULHU`/`MULHS` when the wide multiply's
low half is used.
### Performance
Same-IR A/B (identical IR, stock vs patched `llc`), EC2 metal,
per-target `-march`/`-mtune`, turbo off, one pinned core. ns/elem,
`stock → patched (ratio)`. Full matrix:
https://github.com/llvm/llvm-project/pull/206983#issuecomment-4871421534.
| kernel (AVX-512 256b) | Cascade | Ice Lake | SPR | Zen 4 |
|---|---|---|---|---|
| `udiv` (MULHU) | 1.71x | 1.71x | 1.78x | 1.88x |
| `div` (MULHS) | 1.18x | 1.25x | 1.31x | 2.04x |
| full-128 `lo ^ hi` (guarded) | 1.00x | 1.00x | 1.00x | 1.00x |
### Testing
- New `test/CodeGen/X86/mulhu-v4i64-umul-lohi-guard.ll`:
`umul_lohi_both_halves` (both halves used → scalarizes) and
`mulhu_high_only` (high only → vectorizes), on AVX2 and AVX-512.
- Existing `vector-idiv-{udiv,sdiv}-{256,512}.ll`, `urem-vector-lkk.ll`,
`srem-vector-lkk.ll` show the `MULHU`/`MULHS` vectorization (the signed
ones only on AVX512DQ RUN lines).
- No regressions across `test/CodeGen/X86`.

[libc++] Implement LWG3918: copy elision in `std::uninitialized_move/_n` (#207692)
This implements [LWG3918](https://wg21.link/LWG3918), which guarantees
copy elision for rvalues in `std::uninitialized_move/_n`. It also
implements [LWG4452](https://wg21.link/LWG4452), a minor correction that
makes the helper added by LWG3918 constexpr.
This additionally fixes a bug in `std::uninitialized_move/_n` where they
could create and then access dangling references. The previous
implementation used the following lambda as an implementation detail:
```c++
[](auto&& __iter) -> decltype(auto) { return std::move(*__iter); }
```
When `__iter` is a prvalue, this creates a temporary object within the
lambda's body and `std::move` then returns a reference to that object.
The reference dangles as soon as control leaves the lambda. This
behavior was not permitted by the standard even before LWG3918.
The new implementation fixes the bug by using a helper,
`std::__deref_move(__iter)`, which returns `*__iter` directly when
`*__iter` is already an rvalue.
Resolves #118339.
Resolves #171416.

[Flang][OpenMP] Correct ArrayElements in Reduction Clause (#196094)
Currently, when an ArrayElement is used within a Reduction clause, it
will be lowered with the reduction referencing the box containing the
array, not just the element.
To address this, adjust Flang lowering to track expressions alongside
symbol to ensure that the Array Element context is not lost and
considered when lowering a reduction with Array Element. This ensures
that, when represented in HLFIR, it will be just the element's type,
rather than the full array.
Currently this excludes DO CONCURRENT as it excludes Array Elements, and
is limited to Array Elements but there are options to expand this into
Array Sections in the future.

[SDAG][X86] Uplift pseudo fmin/fmax from X86 (#188489)
X86 has pseudo fmin/fmax operations that implement `x olt y ? x : y` and
`x ogt y ? x : y` respectively. There are other targets that also
support these operations, including wasm and s390x.
On wasm (where I've adopted the "pseudo" terminology from), we currently
create these ops, but incorrectly (wrt signed zero handling). On s390x
we don't, but should to avoid regressions from fixing incorrect
minnum/maxnum formation.
I figured it would make sense to uplift the existing support form X86,
so other targets can benefit from it by just marking the operations
legal.

[DAGCombiner] Fold smax(X, -1)/smin(X, 0) to bitwise shift forms (#206242)
Fixes #206153
`smax(X, -1) = or(X, ashr(X, BW-1))`
`smin(X, 0) = and(X, ashr(X, BW-1))`
`ashr(X, BW-1)` sign-extends the sign bit to all bits 0 for X≥0, -1 for
X<0. OR-ing with X yields X or -1 = smax(X,-1), AND-ing yields 0 or X =
smin(X,0). Both replace a `compare+cmov` with two cheap bitwise
instructions.
The fold is unconditional (not gated on code size), firing whenever the
target has no native `SMAX/SMIN` instruction for the type
(`isOperationExpand`), the type is legal (`isTypeLegal`), and the input
is not a min/max chain (preserving RISCV-P `sati` saturation patterns).

[orc-rt] Add a configurable logging API with a no-op backend (#208214)
Adds ORC_RT_LOG(Level, Category, Fmt, ...), a compile-time-configurable
logging facility for the ORC runtime, along with the default "none"
backend.
The backend is chosen at build time via the ORC_RT_LOG_BACKEND CMake
option (none, printf, os_log), and the lowest level to be compiled in
via ORC_RT_LOG_LEVEL.
The "none" backend implemented here compiles every log site out to
nothing (but still type-checks the format string and arguments in an
unevaluated context so disabled sites cannot bit-rot). Levels are Error,
Warning, Info, and Debug; categories are a typo-safe enum.
The printf and os_log backends are stubbed with #error and will follow.

Revert "[clang][AST] Inline StmtVisitor fallback methods" for STMT macro in debug builds (#208106)
This partially reverts commit 8b50847a31f927d258cf22953035db206d42fc5d.
The LLVM_ATTRIBUTE_ALWAYS_INLINE on STMT macro fallback methods caused
stack overflow in debug builds when processing deeply nested
expressions.
The test many-logical-ops.c with 2000+ logical AND operators would crash
in SequenceChecker due to excessive stack consumption.
Introduce LLVM_ATTRIBUTE_ALWAYS_INLINE_UNLESS_DEBUG which expands to
LLVM_ATTRIBUTE_ALWAYS_INLINE in release builds (preserving the binary
size optimization) but to plain `inline` in debug builds (avoiding stack
overflow).
Apply this to the STMT macro while keeping LLVM_ATTRIBUTE_ALWAYS_INLINE
on BINOP_FALLBACK, CAO_FALLBACK, and UNARYOP_FALLBACK.
Fixes regressions in debug builds only:

[HIP] Use complete toolchain in --offload-device-only (#205243)
Summary:
Since https://github.com/llvm/llvm-project/pull/201457 these targets
defaulted to LTO. However, this caused the default for
`--offload-device-only` to now be LLVM-IR. This is a regression from
prior behavior, so we special case it out. Honestly this would probably
be correct if the behavior started like this, but we shouldn't break
existing code.

implementation consists of the following parts:
- the end of the prolog is marked with a FENCE instruction which
prevents scheduling from moving instructions across the barrier.
- when emitting the PPA1, the FENCE instruction along with other stack
update instructions are used to calculate the length and the offset.

[AMDGPU] Guard block-count upgrade against volatile/atomic grid-size … (#208068)
…loads
AMDGPULowerKernelAttributes upgrades the pre-COV5 pattern
udiv(grid_size_x, group_size_x)
to a direct load of hidden_block_count_x from the implicit args. The
m_Load() pattern matcher does not check whether the matched load is
volatile or atomic, so a volatile or atomic grid_size load would have
been silently deleted and replaced -- dropping its observable side
effects in violation of the LangRef.
Fix: after the pattern match succeeds, cast the matched value to
LoadInst and bail out if !isSimple() (i.e., volatile or atomic).
Add a test case num_blocks_x_volatile_grid_size in
implicit-arg-block-count.ll to verify the volatile load and udiv are
preserved unchanged.

[AMDGPU] Gate fold_pow(x, ±0.5)->sqrt/rsqrt on nsz+ninf fast-math flags (#205592)
AMDGPULibCalls::fold_pow rewrote pow(x, 0.5)->sqrt(x) and pow(x,
-0.5)->rsqrt(x) unconditionally, firing before the
isUnsafeFiniteOnlyMath guard. This is incorrect for two IEEE corner
cases:
pow(-Inf, 0.5) == +Inf but sqrt(-Inf) == NaN
pow(-0.0, 0.5) == +0.0 but sqrt(-0.0) == -0.0
Guard the fold on hasNoSignedZeros() && (IsPowr || hasNoInfs()), where
IsPowr is true for powr/powr_fast. The OpenCL spec requires x >= 0 for
powr, so -Inf is undefined behaviour and the ninf check can be skipped;
-0.0 is a valid input for powr since -0.0 >= 0 by IEEE comparison, so
nsz is still required for all variants. afn alone is not sufficient
since it only permits approximate results and says nothing about the
treatment of infinities or signed zeros.
Update the four autogenerated test files to reflect the new semantics:
- Add nsz (and ninf for pow) to existing afn-only ±0.5 call sites so
those tests continue to exercise the fold as intended. powr tests use
nsz only, documenting that ninf is not required.
- Add afn-only (no nsz/ninf) ±0.5 tests in pow-fast.ll and powr-fast.ll
to document that afn alone does not trigger the fold.

`StoreElement` and `MakeArray` in `unittests/Runtime/tools.h` are static

For now added to LoopVectorizationPlanner, so we can assert that the

The helper should be moved to VPlan directly and the assertion dropped
when no divergences have been found for a while, to make it independent

[Support] Teach llvm::thread about thread-id handling in LLVM-libc. (#207918)
This PR matches the libc++ update from
https://github.com/llvm/llvm-project/pull/198595 and applies similar
changes to `llvm::thread` class. Please see the discussion in that PR
(and linked references to other PRs) for more background / discussions.
`llvm::thread` has methods for extracting integer IDs from running
threads, and as such it needs to know what types are used to represent
those integer IDs - something that e.g. pthreads or C11 threads don't
specify. It assumes that `pthread_t` can be used both as a handle and as
a thread-id on most platforms, with the exception of zOS, where the
custom code is written. In LLVM-libc `pthread_t` is not an integral
type, but today it provides `pthread_id_np_t` type and
`pthread_getunique_np` / `pthread_getthreadid_np` methods as extensions
to extract the integer IDs. Use these methods when building against
LLVM-libc.
This is one of few remaining blockers for building LLVM+Clang on top of
LLVM-libc (https://github.com/llvm/llvm-project/issues/97191).

[Hexagon] Fix 32-bit funnel shift miscompilation with register shift amounts (#205489)
The register-variable 32-bit funnel shifts and the i32 rotates that
lower through them, realize the shift as a 64-bit asl/lsr of the {hi,lo}
combine and take one word of the result. That identity only holds for a
shift amount in [0, 31], and llvm.fshl/fshr define the amount to be
taken modulo 32. The register-form variable shift does not reduce the
amount modulo the operand width, it treats the low 7 bits as a signed
amount in [-64, 63]. So the raw, unreduced amount must be masked with
#31 before the 64-bit shift.
Without the mask, counts >= 32 or "negative" counts are miscompiled: a
count of 63 shifts left by 63, 64 becomes -64 and shifts the value out
entirely, and -1 becomes an arithmetic right shift by 1. In-range counts
0..31 come out correct, which is why a test that only sweeps 0..31 does
not catch it. This is exactly the i32.rotl/i32.rotr miscompile that
caused the WAMR Wasm spec-test suites (which invoke rotates with counts
of 32, 33, and -1) to be skipped on Hexagon.
Fix by masking the amount with (A2_andir $Ru, 31), mirroring the masking
the 64-bit patterns already use. This completes the 32-bit case left
unaddressed by 4fffee037520 ("[Hexagon] Fix 64-bit funnel shift
miscompilation with register shift amounts", #183669), which fixed only
the FShl64r/FShr64r width.

[llubi] Add support for constant inttoptr/ptrtoint expressions (#207028)
This patch adds support for constant inttoptr/ptrtoint expressions to
unblock the running of csmith-generated programs.
The test doesn't cover all the behaviours, as they have been tested by
previous tests.
This patch treats constant inttoptr/ptrtoint expressions as if they are
executed just before the user. However, since ptrtoint exposes the
pointer provenance and inttoptr relies on the current set of exposed
provenances, it is incorrect. Imagine that we have an inttoptr in a gep
instruction and a ptrtoint in an add instruction. They can be freely
DCEd/reordered. In addition, the behaviour also depends on the
initialization order of globals. That is terrible. Nikita's proposal
also mentioned this issue but left it as an open question:
https://hackmd.io/@nikic/SJBt4mFCll#Constant-expressions
>From my perspective, constant expressions are allowed to execute at any
point in the program (before their users). Moving ptrtoint forward or
inttoptr backward will not make the program more undefined. So we can
evaluate all constant expressions before the program entry (i.e., all
globals involved with ptrtoint will be exposed at the start). The only
remaining concern is the use of `ConstantExpr::getAsInstruction`,
because it will convert CEs back into instruction sequences :(

[lldb] Fix assert when `target frame-provider register` succeeds (#208232)
`CommandObjectTargetFrameProviderRegister::DoExecute` never called
`CommandReturnObject::SetStatus()` on its success path.
`CommandObject.cpp` has a `DoExecuteStatusCheck` RAII guard that resets
the result's status to `eReturnStatusInvalid` before `DoExecute` runs,
and asserts on exit that `DoExecute` changed it.
`AppendMessage()`/`AppendMessageWithFormatv()` don't touch status
(unlike AppendError()/SetError(), which call
`SetStatus(eReturnStatusFailed)`), so on the success path the status
stayed eReturnStatusInvalid, tripping the assert.
This went unnoticed because every existing `scripted_frame_provider`
test uses `SBTarget::RegisterScriptedFrameProvider` directly, bypassing
the `target frame-provider register` command entirely. Add a regression
test that exercises the command instead.

[cmake] FindLibXml2: fall back to xmlversion.h when pkg-config has no… (#207797)
… version
LLVM's cmake/modules/FindLibXml2.cmake uses PC_LIBXML_VERSION (from
pkg-config) as the VERSION_VAR in find_package_handle_standard_args.
When pkg-config has no libxml-2.0.pc file (e.g. when linking against a
static libxml2-pic.a that ships no .pc file), PC_LIBXML_VERSION is left
empty after pkg_check_modules fails and the >=2.8 version check reports
'Found unsuitable version ""', causing LLDB_ENABLE_LIBXML2 to be set to
FALSE.
Fix: before calling find_package_handle_standard_args, check whether
PC_LIBXML_VERSION is still empty and if so read LIBXML_DOTTED_VERSION
from the xmlversion.h header. This mirrors the version-detection logic
in the system CMake FindLibXml2 module and ensures LLDB is built with
libxml2 support on installations that use a static libxml2 without a .pc
file.

[CIR][test] Use global instcombine RUN line in AArch64 neon subtracti… (#207894)
Related to https://github.com/llvm/llvm-project/issues/185382
Follow-up to https://github.com/llvm/llvm-project/pull/207115
Include `instcombine` into the global LLVM RUN line and remove the
separate `LLVM-IC` prefix that only covered the narrowing-subtraction
tests in `clang/test/CodeGen/AArch64/neon/subtraction.c`.
Update LLVM CHECK to match the `instcombine` output: bitcast checks are
dropped, the inferred `nsw` flags are added on the widening subs, and
unused shuffle operands are canonicalized to `poison`.

This PR adds lowering for the following intrinsic groups:

It also adds FP16 tests for these intrinsics (implemented in #195021
without tests):
* https://arm-software.github.io/acle/neon_intrinsics/advsimd.html#markdown-toc-rounding-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.

[mlir][linalg] Fix mask rank for masked contiguous `tensor.extract` (#206207)
### Summary
Note: This fix was made mostly by Claude based on a failure case in
IREE. It addresses issue
https://github.com/llvm/llvm-project/issues/206209
When `vectorizeTensorExtract` lowers a `tensor.extract` recognized as a
*contiguous load*, it builds a `vector.transfer_read` whose permutation
map broadcasts the leading iteration dims and only reads the trailing
`min(dstRank, srcRank)` dims of the source. Until now this read was
returned unmasked and masked later by the generic path, which applies a
**full iteration-space identity mask**. When the source rank is smaller
than the loop nest, that mask is over-ranked relative to the
(rank-reduced) read — e.g. a `vector<1x4xi1>` mask on a read whose
inferred mask type is `vector<4xi1>` — and the op fails verification:
```
'vector.mask' op expects a 'vector<4xi1>' mask for the maskable operation
```
(or, after the masked read is rank-reduced by canonicalization in a full
pipeline, `'vector.transfer_read' op inferred mask type ... don't
match`).
### Root cause
The three `tensor.extract` lowering paths in `vectorizeTensorExtract`
handle masking inconsistently:
- **gather** masks itself — correct, its result is full-rank;
- **scalar broadcast** masks itself with a rank-1 mask, explicitly
noting that the generic identity-map masking "wouldn't be valid here";
- **contiguous load** does neither and relies on the generic path, which
masks over all loop dims. That is only correct when the read is
full-rank (`srcRank >= numLoops`); when `srcRank < numLoops` the read
broadcasts its leading dims and needs a rank-reduced mask.
Existing tests only covered the full-rank case (e.g. a
`tensor<80x16xf32>` source in a 2-D nest), so the rank-reducing case was
never exercised.
### Fix
Mask the contiguous read in place, mirroring the scalar-broadcast path,
using a masking map that projects the iteration space onto exactly the
trailing `min(dstRank, srcRank)` dims that are read:
```cpp
int64_t numReadDims = std::min(dstRank, srcRank);
auto maskingMap = AffineMap::getMinorIdentityMap(
linalgOp.getNumLoops(), numReadDims, rewriter.getContext());
Operation *maskedReadOp =
state.maskOperation(rewriter, transferReadOp, linalgOp, maskingMap);
```
This is **behavior-preserving for the existing full-rank case**: when
`min(dstRank, srcRank) == numLoops`, `getMinorIdentityMap` collapses to
the full identity map, producing the same mask (same `activeMaskCache`
key) and identical
IR. Only the previously-broken rank-reducing case changes.
### Testing
- New regression test `@masked_contiguous_extract_rank_reducing_mask` in
`mlir/test/Dialect/Linalg/vectorization/extract.mlir` (1-D source inside
a 2-D loop nest). It fails verification before this change and checks
the rank-reduced mask after it.
- `mlir/test/Dialect/Linalg` (164 tests) and `mlir/test/Dialect/Vector`
+ `mlir/test/Dialect/Linalg/vectorization` (113 tests) all pass.
### Notes for reviewers
- The change is localized to the contiguous-load branch of
`vectorizeTensorExtract`; the gather and scalar-broadcast branches are
untouched.
- No new mask is created in the full-rank case — the existing cached
iteration-space mask is reused, so there is no codegen/IR churn for
current callers.

[flang][cuda] Defer on_device() folding in host copies of OpenACC routines (#208125)
Add a `defer-acc-routines` option to `cuf-function-rewrite`. When set,
`on_device()` is not folded in the host copy of an OpenACC routine (has
`acc.routine_info`, not in a `gpu.module`), because that body is later
cloned into the device routine and would otherwise bake in the host
value (`.false.`). A later run folds each copy in its own context. Calls
already in a `gpu.module` are still folded.

When the number of copy increase this inserts a large number of WAR
hazzards on the reused virutal reg, and the machine scheduler bail out
getting higher reg pressure after sorting.
Beside this, replacing with cvt_u32_u16 provides better code quality

[flang][OpenMP] Fix host-associated user-defined operator reduction (#207413)
A DECLARE REDUCTION for a user-defined operator (e.g.
reduction(.myadd.:x)) was rejected with "Invalid reduction operator in
REDUCTION clause" when the operator was host-associated.
CheckReductionOperator looked up the mangled reduction name in the scope
that owns the operator symbol (the scope where the operator interface is
declared) instead of the scope where the reduction clause appears. The
user-defined reduction is stored in the latter (a child scope), so the
lookup in the operator's owning scope could not find it and the clause
was reported as invalid.
Look up the reduction in the scope of the clause via
context_.FindScope(source). FindUserReduction already searches enclosing
scopes, so this both finds a locally declared reduction and continues to
find one that is host- or use-associated. The lowering side already
resolves the reduction in the current scope, so no lowering change is
needed.
This is a follow-up of PR #202474.

except when perfect nesting is still required
OpenMP 5.0 introduced support for collapsing imperfectly nested loops
for worksharing-loop, simd, taskloop, and distribute constructs. OpenMP
5.1 later formalized this under the Canonical Loop Nest (CLN)
definition. This support is applied retroactively for all OpenMP
versions, since the semantics are safe to implement regardless of
version and for compatibility with other compilers.
The only case where perfect nesting is still enforced is when ordered
semantics require it:
- Pre-5.2: any ordered clause with an argument requires perfect nesting.
- 5.2+: perfect nesting is required only when the loop body contains
ordered directives with doacross (or the legacy depend(sink/source))
clauses.
A `DoacrossFinder` visitor is added to detect doacross directives in the
loop body while correctly not descending into nested OpenMP block/loop
constructs (which have their own binding context).
**Lowering**
Intervening statements are guarded by induction variable comparisons
within the flat `omp.loop_nest` body: "before" code executes when inner
induction variables equal their lower bounds; "after" code executes when
inner induction variables equal their last iteration values (`lb + ((ub
- lb) / step) * step)` for non-unit steps).
**Testing**
- Lowering lit test added
- Semantics tests: updated to remove expected errors for now-accepted
code; new tests added for coverage.
- llvm-test-suite update: (will add once opened)

[LLVM][Maintainers] Volunteer for LoopUnroll (#207802)
I've been reviewing and contributing PRs to the unroller for the past
few months. Since I plan on keeping that up, I figured I'd formally
volunteer as a maintainer.
I'm certainly not an expert on every aspect of the unroller, so no
worries if we feel that we need someone more experienced to fill this
gap.

[IR][NFC] Drop vtable from PassConcept/PassModel (#208168)
The PassConcept/PassModel vtable has a size of 64 bytes (offset to top,
RTTI pointer, complete object destructor, deleting destructor, run,
printPipeline, name, isRequired), which add up to 53kiB (all
targets)/44 kiB (single-target). As more back-end passes get ported to
the new pass manager, this size will increase.
Remove the vtables by replacing the virtual dispatch with explicit
function pointers, initialized when adding the pass to the pass manager.
While this *very* slightly increases the cost of adding a pass, there's
also a very slight win from avoiding the vtable indirection when
running/destructing the pass.

is actually beneficial.)
Also, greatly simplify the class and implement the callbacks using

of 3f5fd4b3c1d670649b59f3631287b6f54c6b85ee, so the only functional
difference is that it provides public copy and copy-assign constructors.
I propose that GDBRemoteDynamicRegisterInfo be removed in favor of
DynamicRegisterInfo.

`llvmGetPassPluginInfo()` is not exported from the LLVM dylib. It is

is, the ids-check workflow would automatically add the `LLVM_ABI`

This fixes the issue by explicitly marking the symbol as ignored.

[MachineCopyPropagation] Fix debug info referring to subregisters. (#207861)
When copy propagation removes a copy, it fixes debug info that refers to

really deal with subregisters; it took any DBG_VALUE that pointed to a
subregister of the old register, and replaced it with the full new
register.
This patch adds logic for subregisters: if a DBG_VALUE refers to a
subregister of the source register, find the corresponding subregister
of the destination register.

[BOLT] Fix DW_FORM_implicit_const values lost during DWARF5 rewriting (#192166)
Summary:
Fix two bugs in DIEBuilder that caused DW_FORM_implicit_const values to
be zeroed out when rewriting DWARF5 debug sections
(--update-debug-sections).
1. In constructDIEFast(), DWARFFormValue was constructed with just the
form code, leaving the value at 0. For DW_FORM_implicit_const,
extractValue() is a no-op since the value is expected to be pre-set.
Fix: use AttrSpec.getFormValue() which initializes the value from the
abbreviation table.
2. In assignAbbrev(), AddAttribute(Attr.getAttribute(), Attr.getForm())
used the two-argument overload which discards the implicit_const value.
Fix: use AddAttribute(Attr) to copy the full DIEAbbrevData.

[SimplifyCFG] Improve reduceSwitchRange to avoid unnecessary subtractions (#198374)
Dense switch cases can sometimes be achieved with only a shift, avoiding
a subtract. Change reduceSwitchRange to check for such cases before
falling back to using a subtract.
The changes to test9 demonstrates that for the purpose of lookup-table
lowering (triggered by the switch-to-lookup flag), the switch range
still ends up normalized to start at 0, the subtraction just happens
after the fshl.
test10 demonstrates where this change is useful, resulting in a dense
switch case with one less subtract.
test11 demonstrates cases where the subtract is still needed in order to
form a dense switch case.

[clang] Reland: fix getTemplateInstantiationArgs (#208285)
Relands https://github.com/llvm/llvm-project/pull/199528
Previous: https://github.com/llvm/llvm-project/pull/207825
This implements a new strategy for collecting the template arguments, by
relying on the qualifiers and template parameter lists to navigate the
template
context of out-of-line definitions.
This greatly simplifies the signature of that function, by removing a
bunch
of workarounds, and simpliffying a couple that weren't removed yet.
Since this now relies on qualifiers and template parameter lists,
this patch expends most of its effort making sure these are placed,
transformed and propagated to template instantiations.
Also makes the explicit specialization AST nodes stop abusing the
template
parameter lists by storing it's own template parameter list, creating a
dedicated field for them, similar to partial specializations.
Fixes https://github.com/llvm/llvm-project/issues/202106
Fixes https://github.com/llvm/llvm-project/issues/202109
Fixes #208100
Fixes #202358
Changes since last landing:
* Instantiated method decls uses a separate path, also needs merging of
deduced return type.
* Handle failures instantiating redeclaration for default arguments
(fails in some error recovery scenarios).

RFC:
https://discourse.llvm.org/t/rfc-make-myst-markdown-the-llvm-docs-format-rip-rest/90840
This change migrates LangRef by itself, since it is quite a large
document with many idiosyncracies.
LangRef makes extensive use of definition lists, which apparently
require enabling the deflist MyST extension in Sphinx conf.py. In part
because definition list boundaries are controlled by indentation,
several of them required manual fixups to get the nesting right. Some of
the issues were pre-existing broken indentation, but this should now be
much better.
I have a verification script that tracks all anchors and ensures that
all previous anchors are carried over to the new document, so no
mid-document links are broken.

incorporates the address of the signing instruction (i.e. the

re-signs using a different scheme. Authenticating the re-signed value
will fail if and only if authenticating the original value with the
incorporated pc would have failed.

[bazel] Correct config.h definitions for musl (#207295)
The Bazel overlay encodes several configure-time config.h results
manually. It currently treats all Linux platforms as having
execinfo.h/backtrace() and mallinfo(). That matches glibc, but is false
when the build is configured for musl libc.
The upstream .bazelrc provides --config=hermetic-toolchain. A musl build
can be selected by pairing that with the platform labels from the
external Bazel module named llvm, for example:
bazel build --config=hermetic-toolchain \
--platforms=@llvm//platforms:linux_x86_64_musl \
--extra_execution_platforms=@llvm//toolchain:linux_x86_64_platform \
@llvm-project//llvm:not
Only define HAVE_BACKTRACE/BACKTRACE_HEADER when not targeting musl, and
only define HAVE_MALLINFO for GNU libc. With the old definitions, this
fails in LLVM Support, e.g.:
Unix/Process.inc:95:19: error: variable has incomplete type 'struct
mallinfo'
Unix/Signals.inc:51:10: fatal error: 'execinfo.h' file not found

-----------
[SimpleLoopUnswitch] Don't latch-redirect trivial unswitch across convergent ops (#207047)
The trivial-unswitch case added in #204934 can redirect a loop-invariant
branch's latch edge to the loop exit, turning it into an exit branch
that then gets hoisted to the preheader. That changes how many
iterations (and, on GPUs, which lanes) execute the loop body.
When the loop contains a convergent operation that runs each iteration,
hoisting the branch lets one (possibly non-uniform) path bypass the loop
entirely and skip the convergent op. Concretely, this miscompiles an
AMDGPU warp reduction (llvm.amdgcn.update.dpp): lanes drop out of the
cross-lane shuffle, so block reductions come back with partial results.
Guard the new latch-redirect transform with the same convergent /
cross-block-token check that isSafeForNonTrivialUnswitching already
applies (refactored into a shared loopContainsConvergentOrTokenOp
helper). Adds a target-independent lit test that fails before this
change and passes after.

[BOLT] Register PIE indirect goto relocations (#206819)
PIE binaries use R_*_RELATIVE dynamic relocations for indirect goto jump
tables. BOLT creates entry points for their targets but does not mark
these addresses as targets from data relocations, so indirect jumps with
unknown control flow (which originates from indirect goto) have no CFG
successors and are interpreted as potential tail calls, while the jump
targets are incorrectly identified as additional entry points.
Add these offsets to the function's list of non-entry relocation
references instead of marking them as entry points. Extend relocation
rewriting to also check whether a block is externally referenced. This
mirrors behavior of data-to-code relocations in non-pie binaries.

Introduce a new VPRegionValue for the header mask, managed by loop

The main benefit is we do not need to materialize the mask early and it
is trivial to find (no more need for patterns hard-coded in findHeaderMask).
It is currently materialized before computing costs, as we compute costs
for part of it currently.

[flang][OpenACC] Fix host fallback for acc.atomic.update (#207597)
The host fallback for `acc.atomic.update` only processed the first
operation in the region and used its result for the store, ignoring the
remaining operations and the `acc.yield` terminator. This generated
invalid IR when the region contained multiple operations.
1.Fix this by cloning all operations in the region and using the operand
of `acc.yield` as the final result to store.
2.Add tests for atomic read, write, update, and capture operations to
cover the host fallback path.

[DirectX] Expand {u,s}mul.with.overflow in DXILIntrinsicExpansion (#207297)
DXIL has no op for the llvm.{u,s}mul.with.overflow intrinsics. These can
be emulated by performing the full multiply using double-width values
and then checking the high-part of the result. However, this should be
avoided for 32-bit values since we don't want to make the shader start
using 64-bit values if it wasn't before. In this case we can use the
UMul and IMul DXIL operations that return the result as separate low &
high values.
Wider (64-bit) multiplies, which can't widen further, compute the high
half with same-width arithmetic instead.
Fixes #207090

unchanged.

[flang][cuda] Register device/constant globals as device-resident under -gpu=mem:unified (#208336)

integer, constant :: zzz; bind(c, name='zzz_from_c') :: zzz
end module
```
```c
extern int aaa_from_c;
#pragma acc declare create(aaa_from_c) // same for zzz_from_c
```
In this code, under `-gpu=mem:unified` a module-scope device/constant
global is registered only as a CUDA variable. Another translation unit
that declares the same symbol on the host can make it be treated as host
memory, so the device symbol is unresolved at run time.
Fix: emit `cuf.register_variable_static` for device/constant globals
under `mem:unified` so they are additionally registered as
device-resident.

[LLDB] Add an API to check whether a variable is writable (#208042)
IDEs may offer functionality to set a variable to a specific value.
There are many situations where this isn't actually possible, for
example, if the variable's value is a constant or the result of a
complex DWARF expression. Instead of offering to change a value only to
have it fail with an error, this API lets the IDE query whether setting
a value is generally feasible so it can hide the action where it isn't
applicable.

[clang] Fix type of the MaterializeTemporaryExpr with incomplete array type. (#187618)
This affects constructs like `int f(int (&&x)[]); int z = f({1});`.
A temporary logically can't have incomplete type: if we don't know the
type, we can't materialize it. Rearrange the casts to make more sense.
I'm not sure this has any practical effects at the moment due to the way
we use skipRValueSubobjectAdjustments; we usually end up ignoring the
type of the MaterializeTemporaryExpr.

[IRBuilder] Add FMFSource overloads for CreateCall (#208171)
CreateCall had no way to set fast-math-flags at creation time, so
callers had to build the call and copy the flags in a second step:
CallInst *C = B.CreateCall(Fn, Args);
C->copyFastMathFlags(Src);
Add FMFSource overloads (mirroring CreateIntrinsic) so the flags can be
copied from a source instruction or FastMathFlags in one call:
CallInst *C = B.CreateCall(Fn, Args, /*FMFSource=*/Src);
The FMFSource parameter has no default, so existing CreateCall callers
are unaffected and overload resolution stays unambiguous.

Assign each mlir::Block a stable ID within its parent region, mirroring

number denotes position in MLIR): Block gains getBlockID() and reads -1u
while it has no parent region; Region gains nextBlockID with
getMaxBlockID() and getBlockIDEpoch(); the block ilist traits assign the
ID on add/transfer and invalidate it on removal; and
GraphTraits<mlir::Block*>/<mlir::Region*> expose
getNumber/getMaxNumber/getNumberEpoch. This makes
GraphHasNodeNumbers<mlir::Block*> true, moving MLIR's CFGLoopInfo and
dominator tree onto the number-indexed path. MLIR never renumbers
blocks,
so the epoch is a fixed 0.
Prerequisite for requiring GraphHasNodeNumbers in llvm::LoopInfoBase and

[ProfileData] Support format version 104 for extensible binary sample profiles (#206297)
This patch adds initial support for format version 104 in extensible
binary sample profiles to support the upcoming on-disk hash table.
This patch sets up the versioning scheme in the reader and writer as a
preparation step without actually introducing the on-disk hash table.
The reader is updated to support format version 104. The writer can
now write format version 104 profiles when requested via
-sample-profile-format-version, but continues to default to version
103 as version 104 is a work in progress. We plan to promote the
default version to 104 once the on-disk hash table support is fully
integrated in a subsequent patch.

[mlir] Make the Python binding type casters well-formed under C++23 (#208093)
The nanobind type/attr/loc/value casters in IRCore.h return a by-value
PyType/PyAttribute/PyLocation/PyValue as their DerivedTy result.
Under pre-C++23 rules, this was a rvalue that would decay to a lvalue
when passed to the DerivedTy constructor.
Under C++23's P2266 (implicit move on return), that return operand is an
xvalue, which cannot bind the PyConcrete* constructors that take a
non-const lvalue reference.
This patch constructs the derived type explicitly (return
DerivedTy(arg);) using the lvalue constructor; this preserves the
pre-C++23 behavior on C++23 builds.

BinaryLoopInfo is one of the last two users.
BinaryBasicBlock already carries a dense [0, size) index (getIndex(),

number, mirroring llvm::BasicBlock/Function.
This makes `GraphHasNodeNumbers<BinaryBasicBlock *>` true, moving BOLT's

[WebAssembly] Use SubtargetFeature's Implies field (#206643)
This makes use of `SubtargetFeature`'s `Implies` field, which lets us
define feature dependencies:
https://github.com/llvm/llvm-project/blob/442c59c75ca384db53a6d6d81686b17ea4b397c3/llvm/include/llvm/Target/Target.td#L568-L571
and removes C++ code that specified feature dependencies.
These are the dependencies specified. EH dependencies are currently only
specified in clang options, and others are specified in
`WebAssemblySubtarget.cpp`.
- exception-handling implies multivalue and reference-types
- bulk-memory implifes bulk-memory-opt
- gc implies reference-types
- reference-types implies call-indirect-overlong
The features in `WebAssembly.td` were sorted in the alphabetical order,
but this changes it because implied features have to come before the
implying feature, e.g., multivalue and reference-types have to come
before exception-handling.
---
One semantic difference from the current code, is, when reference-types
implies call-indirect-overlong,
```console
llc -mattr=+reference-types,-call-indirect-overlong
```
this currently forces call-indirect-overlong to be true despite there is
`-call-indirect-overlong`, because
https://github.com/llvm/llvm-project/blob/442c59c75ca384db53a6d6d81686b17ea4b397c3/llvm/lib/Target/WebAssembly/WebAssemblySubtarget.cpp#L63-L67
But with the `Implies` field, disabling call-indirect-overlong disabled
both features, because TableGen thinks reference-types depends on
call-indirect-overlong, so without call-indirect-overlong,
reference-types can't be enabled. This is not exactly true with the
relationship of reference-types and call-indirect-overlong, but
generally makes sense for true dependencies, like exception-handling
implying (=depending on) multivalue and reference-types.
Also this wouldn't really affect the end users because these are `llc`
flags.

[FIRToMemRef] Fix wrong indexing for converted array_coor over sliced fir.embox (#207749)
FIRToMemRef::convertArrayCoorOp routes through getMemrefIndices, which
only folds the first `rank` triples of sliceInfo.sliceVec into the
memref indices (i.e. the array_coor's own slice); the embox's slice
triples -- which sit at [rank*3 .. 2*rank*3-1] when both are present --
were dropped. Three consequences, three fixes here:
1. Non-collapsed embox slice lbs contribute (lb - 1) per Fortran dim to
each memref index. Fold them in in memref order (reversed Fortran order)
so the reinterpret_cast view lands at the right column.
2. The shapeVec-else stride path used shapeVec[0..rank-1] to build the
outer strides. With both slices present, that's the box's (slice's)
extents. Use shapeVec[rank..2*rank-1] instead -- the parent's extents --
so the outer stride is the parent's leading dim rather than the slice's
own size.
3. Rank-reducing embox slices (undef ub/step triples) have no memref
index position for their (lb - 1) shift. Fold the collapsed dim's (lb -
1) * parent_stride into the reinterpret_cast's flat offset and override
the corresponding memref index entry to 0.

register allocation. The problem with this approach is that it does not
model the potential overlap in live ranges between the destination and
source operands.
As a result, the register allocator assumes it has complete freedom to
allocate registers to the operands. For example, there is nothing
stopping it from allocating:
```
{z0, z1, z2, z3} = FORM_TRANSPOSED_X4 z3, z2, z1, z0
```
However, such cases are hard to expand later, either requiring spills or
complex shuffles. The current expansions of FORM_TRANSPOSED_REG_TUPLE
miscompile in cases like this because, when naively expanded into copies
after register allocation, earlier copies can clobber values that are
still needed by later ones.
For the above case, the incorrect expansion would be:
```
z0 = COPY z3 // z0 clobbered
z1 = COPY z2 // z1 clobbered
z2 = COPY z1 // reads the wrong value of z1
z3 = COPY z0 // reads the wrong value of z0
```
This patch fixes the issue by expanding FORM_TRANSPOSED_REG_TUPLEs into
copy sequences immediately before register allocation (in
`aarch64-post-coalescer`).
For example:
```
%v4:zpr4mul4 = FORM_TRANSPOSED_X4 %v0:0, %v1:0, %v2:0, %v3:0
```
Expands to:
```
undef %v4.zsub0:zpr4mul4 = COPY_INTO_TRANSPOSED_TUPLE %v0:0
%v4.zsub1:zpr4mul4 = COPY_INTO_TRANSPOSED_TUPLE %v1:0
%v4.zsub2:zpr4mul4 = COPY_INTO_TRANSPOSED_TUPLE %v2:0
%v4.zsub3:zpr4mul4 = COPY_INTO_TRANSPOSED_TUPLE %v3:0
```
This is similar to how REG_SEQUENCE is expanded and allows the register
allocator to reason about how the copies may interfere with one another.
To ensure our register allocation hints still apply, we encourage the
scheduler to place FORM_TRANSPOSED_REG_TUPLE nodes immediately before
their users. This keeps the live ranges of the hint nodes
(COPY_INTO_TRANSPOSED_TUPLE) short while extending the live ranges of
their operands. As a result, the register allocator is more likely to
allocate registers to the copy sources first, which works best for our
allocation hints.

[dsymutil] Use DWARFDie::getLanguage instead of manually finding DW_AT_language (#208174)
With DWARFv6, CUs may not have a `DW_AT_language` (but a
`DW_AT_language_name` instead). In
https://github.com/llvm/llvm-project/pull/207151 we made
`DWARFDie::getLanguage` account for this possibility. However, dsymutil
explicitly tries to find `DW_AT_language` in several places.
This patch ensures we go through `DWARFDie::getLanguage` instead in most
of them.
The only way I found this to be testable/observable is by testing the
`isODRLanguage` code paths. Added a test that exercises this.
There is one remaining use of `DW_AT_language` in
`DependencyTracker.cpp`. But was going to address that in a separate
change.

[clang] [serialization] Step into UsingShadowDecl when find existing decl (#208393)
Close https://github.com/llvm/llvm-project/issues/207581
The root cause of the problem is that：enum constant decl, for which its
parent is not enum class, is special. They can be accessed directly
without access its parent. When modules join the game, it becomes more
complex. As for members in other entities like class, we can assume the
member is accessable if their parent are accesable. But it is a
different story for enums. See
https://github.com/llvm/llvm-project/issues/131058 for the whole story
of the backrgound.
Then we didn't write enum constant decl to the lookup table of its
parent of parent in the ASTWriter. So that if other consumer in Sema
wants to access them, they have to get it by entities like exported
using decls. However, the problem is, in ASTReader, when we merge decls,
we use noload_lookup to find existing decls. And the absense of unnamed
enum decl in the parent of its parent's lookup table makes the merge
fails. For enum constant decl in named enum, they will still have a name
lookup table. So we will merge them somehow. But for enum constants in
unnamed enum, they were removed from the only lookup table so the merge
fails. This is the whole story of the current issue.
To fix this, when we merge decls, we step into the UsingShadowDecl to
find the real decls. This is fine as we never merge decls with different
kinds. We can even call this a tiny optimization.

[VPlan] Add VPInstruction::Intrinsic opcode, use for scalar intrinsics. (#207541)
This patch adds a new Intrinsic opcode to VPInstruction, initially used
for generating calls to scalar intrinsics. The intrinsic ID as integer
is the last operand (i.e. the called function). Alternatively we could
also create the needed intrinsic declarations and pass the function
directly, but that would add potentially unused declarations, if we
decide to not vectorize.
The first patch migrates just VScale, but there are other opcodes
matching directly to intrinsics, which will be replaced in follow ups.
It also gives more flexibility going forward, e.g. allows emitting
min/max intrinsics when expanding SCEV min/max expressions.

[Offload] Make compressed offload bundle header little-endian (#206744)
The compressed offload bundle (CCOB) header integer fields (Version,
Method, FileSize, UncompressedFileSize, Hash) were serialized and read
in
host-native byte order. The on-disk format is little-endian, so on
big-endian hosts these fields were byte-swapped: writing produced a
malformed header, and reading misparsed the size, making
`llvm-objdump --offloading` crash/misbehave on s390x. This is also why
the
earlier bundle-size fix had to be reverted.
Make the header little-endian on every host:
- Read side: declare the `RawCompressedBundleHeader` fields as
`support::ulittle16_t` / `ulittle32_t` / `ulittle64_t`, so the bytes are
always interpreted as little-endian regardless of host.
- Write side: emit the header with
`support::endian::Writer(OS, endianness::little)` instead of host-native
`OS.write(&field, sizeof field)`.
Also revert the temporary big-endian test skip added in #205999
(host-byteorder-little-endian guard on fatbin-coff-compress.test): with
the
header now little-endian, the test runs correctly on big-endian hosts.

[Flang][MLIR][OpenMP] Fix declare_target globals visibility (#208188)
This patch introduces various changes to the handling of
`declare_target` global variables in Flang:
- Non-`declare_target` globals are unconditionally made "internal" when
compiling for an OpenMP offload target. This prevents potential symbol
redefinition issues related to globals that don't actually exist on the
device.
- Local SAVE variables handling for OpenMP offloading programs is fixed
to prevent their associated "internal" linkage from producing broken
device code for `declare_target enter(...)`.
- When globals are indirectly accessed from the target device (e.g.
`declare_target link(...)`), the associated and unused full-storage
global is marked with "internal" linkage to facilitate later removal.
- `declare_target device_type(host) enter(...)` variables are set to
external linkage when compiling for a target device, causing linker
errors if accessed. This mirrors Clang's behavior.
Fixes #195188, fixes #195468.

[Flang][MLIR][OpenMP] Move host op filtering to the omp dialect (#208189)
The MLIR pass that removes operations exclusively intended for the host
from OpenMP target offload modules is currently defined as part of
Flang. However, this is a feature that would benefit from being reusable
by other frontends, as removing such operations is a requirement for all
OpenMP target device modules prior to LLVM IR translation.
By moving the `omp-host-op-filtering` pass out of Flang, it had to be
updated to work on a lower-level LLVM dialect-based representation,
rather than FIR. This simplified some of the existing edge cases, such
as `fir.declare` ops and `fir.boxchar` type handling. In addition, new
function arguments are introduced as placeholders and return values from
host-only functions are removed, producing a cleaner result and
simplifying the pass as compared to previously.
As a result of a later execution of this pass, dynamic dispatch of host
functions via dispatch table using `fir.dispatch`, `fir.type_info` and
`fir.dt_entry` ops would break due to the removal of `fir.dt_entry`
operations pointing to deleted host functions, while `fir.dispatch` ops
pointing to the same functions would remain. The
`omp-function-filtering` pass is updated to prevent `fir.dt_entry` from
being deleted and let them point to an undefined symbol. This lets FIR
lowering to LLVM work well enough to get to the host op filtering stage,
where any resulting operations for this host dynamic dispatch are
cleaned up.

[ISEL] Fix x86-64 instruction selection bug leaking upper 32 bits (#205600)
The x86 backend had optimization patterns that matched:
`(or (and GR32:$dst, -256), (i32 (zextloadi8 addr:$src)))`
and lowered it to:
`(INSERT_SUBREG (i32 (COPY $dst)), (MOV8rm i8mem:$src), sub_8bit)`
INSERT_SUBREG for sub_8bit emits a movb instruction which preserves the
upper 56 bits. Now, if the GR32 dst came from a node that does not zero
the upper 32 bits (like IMPLICIT_DEF or EXTRACT_SUBREG), those upper 32
bits would be leaked into the resulting register without being zeroed.
This fixes it by ensuring the input operand satisfies def32 which
requires the upper 32 bits of the register to be set.

AMDGPU: Introduce amdgpu triple arch (#206480)
Move towards using the triple for representing incompatible
ISA changes. Use the subarch field to represent the various
incompatible cases. Previously we pretended a single triple arch
was universally compatible, and only distinguished by function
level subtargets. Move towards using distinct triples to enable
more sophisticated toolchain handling in the future, like proper
runtime library linking.
Introduce a new subarch per unique ISA, but also introduce
"major subarches" which are compatible by a set of covered
minor ISA versions. These map to the existing generic targets.
There are a few placeholder subarch entries, which currently
have missing backing generic arches for codegen.
This should be the preferred triple arch name going forward,
but is treated as an alias of amdgcn. This does not yet change
clang to emit the new triples.

[LLVMABI] Implement the System V X86-64 ABI (#194718)
This PR implements the System V X86-64 ABI for the LLVM ABI Library
prototyped in https://github.com/llvm/llvm-project/pull/140112, and
wires it into clang's Codegen.
`X86_64TargetInfo` is a direct parallel to
`clang::CodeGen::X86_64ABIInfo`, but operates entirely on the
`llvm::abi` type system.
The AMD64 ABI classification spec, argument/return lowering , and the
supporting helpers are all reproduced against `llvm::abi::Type` and
FunctionInfo, keeping the ABI logic frontend-independent.
This, similar to the [BPF ABI implementaiton
](https://github.com/llvm/llvm-project/pull/194031/changes)is gated
under the `-fexperimental-abi-lowering` flag.

[OffloadBundler] Bound compressed bundles by header size, not magic scan (#206745)
When multiple offload bundles are concatenated, the unbundler
(clang-offload-bundler) and llvm-objdump --offloading located the end of
a compressed bundle, and the start of the next one, by scanning for the
next "CCOB" magic string starting right after the current header.
A zstd/zlib-compressed payload can legally contain those four bytes, so
the scan could stop in the middle of the compressed data and truncate
the bundle, corrupting the embedded code object. In practice this
produced a "decomposition" failure for hipBLASLt bf16 GEMMs on gfx942.
Use the authoritative total-size field recorded in the compressed bundle
header (format V2/V3) to compute the exact bundle boundary, and only
scan for the next magic past that point. Legacy bundles without a
recorded size (V1) keep the previous magic-scan fallback.
A skippable-frame fixture that embeds "CCOB" inside the compressed
payload is added to exercise the boundary logic from both
clang-offload-bundler and llvm-objdump --offloading.

[AArch64] Don't merge branch conditions that both compare memory loads (#206504)
`shouldKeepJumpConditionsTogether` decides whether to fold two integer
branch conditions into a CMP/CCMP chain by pricing the RHS
dependency-chain latency. That ignores register pressure: when both
conditions compare loaded values, merging pins all the loaded operands
live at once to feed the chain instead of consuming them at each split
compare-and-branch. On a load-store target that extends their live
ranges across the region the branch dominates.
Decline to merge when both sides are integer compares of loaded values,
mirroring the machine CCMP pass (which won't speculate loads).

The goal for us is to be able to demangle Microsoft mangled function
names toward something that reads more like AST function names and
Itanium demangled names. All defaults remain the same and no existing
code or tool user should be impacted by the change.
* Make the OF_NoTagSpecifier flag accessible from `microsoftDemangle`
* Add a flag to skip the "void" keyword when there is no parameter
* Add a flag to skip the type descriptions
* Respect MSDF_NoCallingConvention with function pointers
* Add unit tests.

[flang][acc] Remove dangling operands in OpenACCUtilsTiling (#208261)
When TILE has more dimensions than the loop's collapse count,
uncollapseLoops() synthesizes an inner loop via `createInnerLoop()`,
which
strips gang attributes from it but forgot to clear the gang operand
values. This left the loop with a non-empty gang operand list but no
device-type attribute, causing LoopOp::getGangValue() to dereference a
null attribute and crash with an assertion failure when the loop also
had
`GANG(STATIC:N) (or NUM/DIM)`.
Fix: also clear the gang operands when stripping gang attributes, so the
loop ends up fully gang-free.

[LLVM][NFC] Remove some global constructors (#208407)
Largely by converting relevant functions or variables to constexpr,
changing the type, converting to static locals, or by outright removal.
PunnedPointer assignment can never be constexpr, because std::memcpy is
not constexpr and type punning is not permitted in a constant-evaluated
context.

[SPIR-V] Fix truncated LinkageAttributes OpDecorate for numeric-named functions (#207332)
LLVM IR allows functions with numeric names (e.g. `@0`). There function
return empty strings on `getName()`, so emitting a `LinkageAttributes`
decoration for it is meaningless.
Fix: skip emitting the `LinkageAttributes` decoration for non-entry
functions with an empty name. Also add a `report_fatal_error` for the
case where an entry point function has no name, since that is invalid
input.

[NVVM][MLIR] Fixed valgrind leak in MMAOp (#208063)
MmaOp::getIntrinsicID triggers an uninitialized-read warning under
Valgrind. `intOverflowBehavior` is optional; in the generated selector
its `has_value()` guarded access can be speculatively loaded before the
guard, reading the empty std::optional's uninitialized payload.
The read is benign: the payload is correctly stack-allocated but
uninitialized while empty, and the loaded value is discarded by the
guard, so this is not incorrect / undefined behavior.
This MR keeps the attribute as optional, but the lowering now resolves
it to a concrete value (wrapped when omitted) before calling
getIntrinsicID, so the selector always reads an initialized value.
`wrapped` matches the PTX spec and the existing lowering, where an
omitted attribute already selected the non-satfinite intrinsic;
intrinsic selection and printed IR are unchanged. Documentation updated
to correct the stale default.

[clang][docs] Rewrite 20 selected Clang docs from reST to Markdown (#208310)
Tracking issue: https://github.com/llvm/llvm-project/issues/201242

RFC:
https://discourse.llvm.org/t/rfc-make-myst-markdown-the-llvm-docs-format-rip-rest/90840
This change was produced with rst2myst plus LLM cleanups.
I manually paged through all of the linked HTML documents looking for
visual artifacts, and I fixed everything I found.
To reviewers: Please spot check the generated HTML below, and spot check
the diff to look for artifacts. This change is too large to review
everything line-by-line, but if you check 10 pages of documentation, and
only find one migration bug, I hope you think that this is good enough
to land. We have existing reST bugs that this fixes (mostly italic
blocks that should be code font spans).

Clang 21.1.8 segfaults during SFINAE overload resolution for
T::getChecked
when matching non-pointer arguments against an unconstrained
MLIRContext*
parameter.
This patch avoids the crash by adding an explicit SFINAE constraint to
the second overload of StorageUserBase::getChecked, ensuring that it is
only considered when the second argument is convertible to MLIRContext*.

[CIR] Represent 'empty' fields in structs/unions (#207033)
Since we do field based GEPs, it isn't really possible to do a
get-address-of a field without representing all the fields in a CIR
struct. This patch makes sure we do that, so we can do the proper GEPs.
This patch also as a drive-by fixes the case where we were searching for
the 'path' inside of an empty base, which we don't represent (and
probably should not need to?).
This patch ALSO adds some NYI diagnostics for cases where we try to get
the address of a `no-unique-address` field, which we are not currently
representing. In the future, we are going to have to start representing
no-unique-address fields inside of a struct as well (plus figure out how
to lower it properly in a way that gets the offsets right), but it isn't
clear this is immediately necessary (as you'd have to take an address of
one to notice?).

[Flang][OpenMP] add Apply clause for OpenMP Flang (#204225)
This patch adds a parser and basic checks for the Apply clause from
OpenMP 6.0 in Flang.
It is missing semantic checks for nesting loop transformations that are
being worked on.

[VectorCombine] Fix bailing out of the foldSingleElementStore with a freeze-pending index (#207702)
`foldSingleElementStore` calls `canScalarizeAccess` to decide whether a
single-element store can be scalarized. When the insert index is not a
constant, is provably in-bounds and may be poison, `canScalarizeAccess`
returns `SafeWithFreeze` and stashes a `ToFreeze` value that must later
be consumed by `freeze()` or cleared by `discard()`.
The bail-out for memory being modified between the load and store was
folded into same condition as the scalarizability check:
```cpp
auto ScalarizableIdx = canScalarizeAccess(...);
if (ScalarizableIdx.isUnsafe() || isMemModifiedBetween(...))
return false;
```
When the index took the `SafeWithFreeze` path and memory was modified
between the load and the store, `isMemModifiedBetween` returns true and
hit `return false` while ScalarizableIdx still holds a live `ToFreeze`.
Its destructor then raises:
> Assertion !ToFreeze && "freeze() not called with ToFreeze being set"
### Fix
Move the `isMemModifiedBetween` bail-out above the `canScalarizeAccess`
call so the freeze-pending result is never constructed on the path where
we give up.

Prefetch is a hint that migrates a USM allocation between the host and a
device so subsequent accesses on the target side are faster.

[mlir][tosa] Add constant block scaled support (#205506)
This commit adds support for block scaled tensors.
In particular, the block scaled type has been extended with the
`DenseElementTypeInterface` to allow block scaled data values to be
specified in dense element attributes.
The block scaled type has also been extended to allow optional scale
values to be specified by the type. For now, scale values are not
expected to be propagated beyond their use in the attribute input of a
constant operation. In the future, we may want to propagate these values
to allow certain optimizations.
The `tosa.const` operation has also been updated in the validation pass.

[CodeGen] Disable exact dynamic_cast for duplicable vtables (#205929)
Add `TargetInfo::getVTableUniqueness()`, which returns a
`VTableUniquenessKind` that describes whether a target's ABI guarantees
a class's vtable has a single address program-wide. Apple Mach-O targets
return `UniqueIfStrongLinkage`, since a vague-linkage (weak) vtable may
be autohidden and duplicated per image, while a vtable with strong
linkage (e.g., a class with a key function) still has a unique address.
Every other target keeps the default, `AlwaysUnique`.
Rename the `CodeGenOpts` flag backing `-f[no-]assume-unique-vtables`
from `AssumeUniqueVTables` to `DisableExactDynamicCast`, defaulting to
false so the optimization stays on unless `-fno-assume-unique-vtables`
is given. Use it together with `getVTableUniqueness()` in
`ItaniumCXXABI::hasUniqueVTablePointer()` so a weak vtable on a target
that may duplicate vtables no longer qualifies for the exact
`dynamic_cast` optimization; a vtable with a key function, or any vtable
on a target with `AlwaysUnique` semantics, is unaffected.

[CIR][AArch64] Lower NEON vfms builtins (#207022)
Lower additional AArch64 NEON fused multiply-subtract builtins in CIR.
This covers the ACLE wrappers from section 2.1.1.2.5:
- vfms_f32, vfms_f64, vfmsq_f32, vfmsq_f64
- vfms_lane_f32, vfms_lane_f64, vfmsq_lane_f32, vfmsq_lane_f64
- vfms_laneq_f32, vfms_laneq_f64, vfmsq_laneq_f32, vfmsq_laneq_f64
- vfmss_lane_f32, vfmss_laneq_f32
- vfmsd_lane_f64, vfmsd_laneq_f64
The lowering reuses the existing FMA paths by negating the multiply
operand before emitting llvm.fma. Vector lane forms splat the selected
lane, while scalar lane/laneq forms extract the selected element before
the FMA.
Move the existing ACLE coverage into
clang/test/CodeGen/AArch64/neon/fused-multiply.c and add direct LLVM,
CIR-to-LLVM, and CIR checks. The replaced old-style checks are removed
from the legacy test files.

[VectorCombine] Handle widening/narrowing bitcasts in foldShuffleToIdentity (#187870)
Track lane indices through vector bitcasts that change element count in
foldShuffleToIdentity. Widening bitcasts (e.g. <2 x i32> -> <4 x i16>)
compress R consecutive destination lanes into one source lane, while
narrowing bitcasts (e.g. <4 x i16> -> <2 x i32>) expand each destination
lane into R source lanes.
Also fix identity check, splat mask, and destination type construction
to use Item.size() instead of Ty->getNumElements(), since the Item
vector changes size when passing through element-count-changing
bitcasts.

[WebAssembly] Don't use passive segments for bss in coop threads (#208284)
This commit is an update to `wasm-ld`'s behavior with bss data segments
with `--cooperative-threading`. Previously bss segments were forced to
become passive data segments meaning that a `start` function was emitted
with a `memory.fill` that set the required region of memory to 0. This
isn't required for coop threads though because the module is only
instantiated once and the default pattern for memory is 0, so only
special treatment of TLS segments are required.

Both COSHAPE and THIS_IMAGE(coarray [,team]) return integer arrays whose
element type is determined by the Fortran KIND argument (default: i32).
The lowering code was ignoring resultType in both cases and hardcoding
i64, which caused downstream type mismatches:
- COSHAPE: SimplifyHLFIRIntrinsics assertion in PRODUCT(COSHAPE(y)) when
the product input type (i64) did not match the declared result type
(i32).
- THIS_IMAGE(coarray): MLIR verifier error on arith.cmpi with mismatched
operand types (i64 vs i32) in comparisons like THIS_IMAGE(a) /=
[5,0,-7].
Fix: derive eleTy from resultType in both genCoshape and genThisImage
and propagate it into the mif.* op's result type. In MIFOpConversion,
extract a shared convertI64SeqToEleTy helper that post-converts the i64
scratch buffer written by the PRIF runtime into the
declared-element-type buffer when the two types differ. Both
MIFCoshapeOpConversion and MIFThisImageOpConversion call this helper.

[libc++] Remove benchmark::DoNotOptimize from custom predicates in benchmarks (#208412)
The point of the custom predicates is to defeat any detection of special
predicates within the library. There isn't much point in adding
`benchmark::DoNotOptimize` on top of that. It can actually hurt, since
it may hide performance changes due to how much/which information we
provide to the compiler.

[SLP] Support FAdd/FSub as interchangeable instructions
fadd(x, c) and fsub(x, c) are interchangeable via fadd(x, -c), so treat
them like the existing Add/Sub/Mul/Shl/AShr/And/Or/Xor interchange in
BinOpSameOpcodeHelper. This lets a mixed fadd/fsub bundle vectorize as
a single op instead of needing an alt-shuffle/split node.
Restrict the interchange to a constant RHS. A constant LHS (e.g.
"0.0 - x") cannot be moved to the other opcode without also swapping
the variable operand, which would misalign it against lanes that keep
their native opcode and produce a node too expensive to vectorize.

[ConstraintElim] Skip overflowing row combinations in FM elimination. (#208404)
The constraint system uses 64-bit coefficients and previously aborted
the entire elimination as soon as a single row combination overflowed.
This is unnecessary pessimistic and can lead to lost optimizations if
the system contains constraints with large coefficients which do not
contribute to a particular solution (e.g. signed wrap checks).
Instead, skip only the overflowing row combination and continue.

[CodeGen] Mark weak vtables unnamed_addr on duplicable-vtable targets (#205930)
When a target's `getVTableUniqueness()` is `UniqueIfStrongLinkage`, as
on Apple Mach-O, the platform may emit a class's weak vtable as a
separate copy in more than one linkage unit. A symbol that can
legitimately exist at several addresses has no meaningful address, so
such a vtable can be marked `unnamed_addr`.
On Mach-O, a weak vtable that is `unnamed_addr` lowers to a
`.weak_def_can_be_hidden` definition, which the static linker coalesces
and then drops from the dynamic export trie. Keeping these vtables out
of the exported symbol set cuts the work dyld has to do at load time.
#200108 dropped `unnamed_addr` from vtables because the exact
`dynamic_cast` optimization compares an object's vtable pointer against
a known vtable address and depends on that address being unique. Adding
`unnamed_addr` is safe here because that optimization is never performed
for these weak vtables, so nothing relies on them having a unique
address.

2. (-D_VARARG_EXT_) uses __builtin_va_list typedef for va_list.
The __builtin_zos_va_list type is `char * [2]`.

Inlining can leave a `fir.declare`'s dummy_scope operand (`!fir.dscope`)

rematerialized inside, since `fir.dummy_scope` wasn't registered as an
OutlineRematerializationOpInterface candidate.
This dangling, unmappable live-in is illegal for parallelization.
Fix: Added `OutlineIdentityOperandOpInterface`, implemented by
`fir.declare/hlfir.declare`, so `OffloadLiveInValueCanonicalization`
drops their dummy_scope operand (an identity token that must never be
duplicated) instead of cloning it when sinking/rematerializing them into
offload regions.

[Clang][Sema] Ensure explicitly defaulted functions respect FP pragmas from their declaration site (#207429)
Currently, when an explicitly defaulted function is synthesized (e.g.,
at its first use), it erroneously adopts the floating-point (FP) pragma
state of the synthesis site rather than its declaration site. This leads
to mismatched or incorrect FP features being applied to the generated
body, completely ignoring `#pragma STDC FENV_ACCESS` pragmas that were
active when the function was explicitly defaulted.
This change should fix this issue by capturing and restoring the FP
features at the appropriate times.
Fixes #207266
I also added the following fixes to support the above:
- AST Importer Fix: Updated ASTImporter::VisitFunctionDecl to correctly

Add an attribute which indicates that a call is to an intrinsic

in a module found in the intrinsic path.
This allows us to, when optimizing, make sure that we correctly identify
calls to intrinsic functions whose behaviours we know, and not
user-defined functions whose names happen to match.

This patch replaces std::set with SmallVector and llvm::sort in
SortedCallTargetSet and sortCallTargets.
Since the keys in CallTargetMap are already guaranteed to be unique,
using std::set for sorting allocates unnecessary tree nodes on the
heap.
This patch also removes unnecessary const from return-by-value types
to enable move semantics.

tail folded, i.e. it has a header mask (materialized or not).
Similarly to https://github.com/llvm/llvm-project/pull/207784, it also
adds a wrapper to LoopVectorizationPlanner that asserts that cost model
and VPlan decision agree. The wrapper should be removed after no

[clang] Fix crash in DiagnoseMissingSemiAfterTagDefinition for annot_template_id (#208119)
DiagnoseMissingSemiAfterTagDefinition checks whether the token after a
tag definition could be a scope specifier before calling
TryAnnotateCXXScopeToken. It accepted annot_template_id unconditionally,
but TryAnnotateCXXScopeToken asserts that MightBeCXXScopeToken() holds,
which only accepts annot_template_id when followed by ::.
When the token is annot_template_id not followed by :: (e.g. union { }
::foo<int>; where ::foo<int> is annotated as a template-id after a
missing semicolon), the check passes but MightBeCXXScopeToken() returns
false, firing the assertion.
This patch adds the same NextToken().is(tok::coloncolon) guard that
MightBeCXXScopeToken uses for annot_template_id.
Fixes #207992

[RISCV] Fix incorrect fixed vector lowering for VECTOR_DEINTERLEAVE (#207254)
Partially address #207136
Previously this part of the logic simply converts each operand into
scalable vector and pass on. This will run into problem when the
scalable vector container is larger than the actual fixed vector.
This patch fixes this issue by storing individual fixed vector operands
directly onto the stack, before loading them back with segmented load
just like its scalable vector counterpart

[Clang] Fix crash involving `__attribute__((cleanup))` attributes and improve handling of multiple `cleanup` attributes (#207785)
Clang would previously crash on this code:
```c
#define C(x) __attribute__((cleanup(x)))
void foo(double *x) {}
void bar() { C(foo) C(foo) baz8; }
```
Here, we were trying to query properties of `VD->getType()`, which would
crash because type of the variable declaration is null here (because the
user didn’t write a type); avoid this by bailing out early if the
declaration is invalid.
Additionally, this patch fixes a GCC compatibility issue: in code such
as
```c
#define C(x) __attribute__((cleanup(x)))
void f1(double *x);
void f2(double *x);
void bar() { C(f1) C(f2) double x; }
```
Clang would only use the first cleanup attribute, whereas GCC only uses
the last one; I’ve changed our behaviour to match GCC’s and added a
diagnostic that informs the user that only the last cleanup attribute is
actually used.
Fixes #191829.

[z/OS][Clang] Add compare and swap builtin functions (#202362)
Implements the following compare and swap builtins:
```
int __cs(unsigned int *, unsigned int *, unsigned int), 4 byte compare & swap
int __cs1(void* OP1, void* OP2, void* OP3), 4 byte compare & swap
int __csg(void* OP1, void* OP2, void* OP3), 8 byte compare & swap
int __cds1(void* OP1, void* OP2, void* OP3), 8 byte compare & swap
int __cdsg(void* OP1, void* OP2, void* OP3), 16 byte compare & swap
```
The implementation utilizes the llvm cmpxchg intrinsic to generate the
CS instructions, then it generates a store instruction to store OP2 into
OP1, and finally invert the success flag of cmpxchg by an XOR
instruction with 1 and return the flag.

[RISCV] Support Zdinx registers in -fzero-call-used-regs (#206323)
First, this patch makes the backend consider GPRF16 and GPRF32 registers
as GPR. These registers are aliases of normal GPR but for use with the
Zdinx extension (floating points instructions on GPR).
Second, it teaches the general -fzero-call-used-regs logic to handle
used registers that span over multiple physical registers. One example
of this is `GPRPair` in the RISC-V backend.

[SampleProfile] Introduce stabilizeTable (NFC) (#208501)
This patch adds stabilizeTable to replace duplicate code involving
O(N) heap allocations and hash lookups. The new helper function
returns pointers to key-value pairs sorted by key.
Since the keys in MapVector are already guaranteed to be unique,
using std::set for sorting allocates unnecessary tree nodes on the
heap.

[mlir][RemoveDeadValues] Use `SymbolUserMap` to avoid quadratic symbol lookups (#205448)
`processFuncOp` previously called `funcOp.getSymbolUses(module)` for
every function, which walks the entire module to find that function's
callers. Since `processFuncOp` runs once per function, the pass was
effectively *O(numFunctions * numOperations)*.
Build a `SymbolUserMap` once up front in `runOnOperation()` and look up
each function's callers in *O(1)*, making the collection phase linear in
the size of the module.
This is behavior-preserving: the map is read only during the
mutation-free collection walk, and all IR erasure happens afterwards in
`cleanUpDeadVals`, so the map cannot become stale while it is in use.

[Support] Optimize signal handling file removal code (#173586)
clangd/clangd#1787 describes how LLVM's code for removing partially
written files when taking a fatal signal is slower than it should be.
This code was substantially rewritten by JF Bastien in
aa1333a91f8d8a060bcf5 to make it (more) signal-safe.
As written in 2018, the logic always allocates a new node for every file
we attempt to protect, and those nodes are added to a global singly
linked list and never removed. If you open a lot of output files,
suddenly output file opening becomes O(n^2), which is what happened
during clangd indexing.
Removing files on signals in a multi-threaded environment is really
complicated! We can use locks to synchronize between threads that are
writing to the list, but we cannot use locks to synchronize against
re-entrant signals, and we don't have any great tools for masking or
delaying things like SIGTERM. This makes it difficult to assert that we
have the one and only reference to a node, even after removing it from
the linked structure, so we can safely deallocate it.
This implementation sidesteps that problem by reusing nodes on the list
with a null Filename pointer. The Filename is null if the file no longer
needs to be removed. We replace the filename with a different sentinel
while removing files using a CAS operation to simulate a lock acquisition.
* Case 1: This is the normal case, works as intended, the list should
grow in length to the number of concurrently open files that must be
removed on exit, which should be O(# threads)
* Case 2: In this case, the signal handler will leak the filename string
without a GC root for it, which is fine, since we're exiting.
I added a benchmark, and this
change makes it 16x faster, and the profile shows that the time is no
longer mostly spent in this signal handling code.

[clang][ssaf] Add SARIF transformation-report format (#208327)
Adds the built-in `TransformationReportFormat`, registered under the
file extension `sarif`. The writer drives clang's existing
`SarifDocumentWriter` (`clang/Basic/Sarif.h`) to produce a SARIF 2.1.0
JSON document. The tool driver name is `clang-ssaf`; the long `fullName`
carries the transformation's name.
Token-range `CharSourceRange`s are canonicalized to char ranges via
`clang::Lexer::getAsCharRange` before being attached to results; invalid
ranges (including default-constructed ones) are treated as "no location"
— the writer omits the result's `locations` key rather than fabricating
one. Source edits are not embedded in the report; the writer never emits
a `fix` or `fixes` key.
Anchored via `SSAFSARIFTransformationReportFormatAnchorSource` so static
builds keep the registration.

[lldb] Use `llvm::APInt` for `VariantMember` Discriminants (#188487)
resolves #177812
It currently uses a `uint32_t` even though Rust can output 64- and
128-bit discriminants. This became a more obvious issue when Rust
started niche-optimizing based on the capacity of strings (which are
`NoHighBit` values, guaranteed to be less than `u64::MAX / 2`), rather
than the `NonNull` heap pointer. With this optimization, the `None`
variant of strings is 9223372036854775808, which LLDB truncates to 0.
This means whenever the capacity is 0 (e.g. `Some(String::new())`, LLDB
will mistakenly read it as the `None` variant. Additionally, when trying
to determine the `None` variant, lldb will read the discr from memory
correctly (9223372036854775808), and the visualizer scripts will compare
that to the value in the variant name (`$variant$0`), see that it
doesn't match, and incorrectly decides that it must not be the `None`
variant.
This patch simply swaps the `uint32_t` with an `llvm::APInt`.
Sample program:
```rust
#[repr(u128)]
enum BigDiscr {
Value(u64),
None = 0x16151413121110090807060504030201,
}
fn main() {
let big_discr_none = BigDiscr::None;
let big_disr_some = BigDiscr::Value(31);
let some_string = Some(String::from("asdf"));
let some_empty_string = Some(String::new());
let none_string: Option<String> = Option::None;
println!("Hello world!"); // break
}
```

[HLSL] Reject unbounded resource array and noinline function resource parameters (#208111)
Fixes #180808.
This issue involved two bugs:
- `noinline` functions accepted resource parameters in the frontend,
which crashed the backend since valid DXIL cannot be generated for
resources passed across a function call. This change adds a new check in
`SemaDecl.cpp` that rejects resource parameters on `noinline` functions,
as well as a new `resource_params_noinline.hlsl` test.
- The check for incomplete resource array parameters queried the array's
element type to decide if it was a resource. When the parameter was the
first use of the resource type, the element was still incomplete and
wouldn't register as a resource, so the check would be skipped and the
compiler would later crash. This change fixes the check to now force
element completion with `isCompleteType` before querying the type, and
updates `unbounded_resource_arrays.hlsl` to test this.
This change also fixes the `unbounded_resource_arrays.hlsl` test in
general; the `not` in the RUN command was inverting the result and
hiding an actual failure (one of the expected error messages was
misspelled).

[mlir][xegpu] Fix crash on 0D vector in vector-to-xegpu transfer lowering (#205812)
`transferPreconditions` accepted rank-0 vectors, which then reached
`computeOffsets` and indexed an empty `SmallVector` (`broadcasted[0]`),
asserting `idx < size()` and crashing. For example:
```mlir
vector.transfer_write %arg0, %arg1[%1] : vector<f32>, memref<3xf32>
```
This is valid IR (the verifier accepts it; 0D vector transfers are part
of the vector dialect spec), so the conversion pass should not crash on
it.
Bail out via `notifyMatchFailure` for 0D vectors in the shared
`transferPreconditions`, so both `transfer_read` and `transfer_write`
are left unconverted instead of crashing. This matches how the core
vector lowering already treats 0D transfers as an unsupported corner
case (see `mlir/lib/Dialect/Vector/Transforms/LowerVectorTransfer.cpp`).
Regression tests are added for 0D `transfer_read` and `transfer_write`.

Example — shape_cast [8,32,32] -> [256,32] (consumer lane_layout=[8,4],
lane_data=[2,1], order=[0,1]),
inferred source layout:
before: inst_data=[8,2,4], lane_layout=[8,1,4], lane_data=[1,2,1],
order=[1,0,2] # lanes on slow dim
after: inst_data=[1,16,4], lane_layout=[1,8,4], lane_data=[1,2,1],
order=[1,0,2] # lanes wrap to fast dim
This also fixes wrap-around, e.g. [2,16]->[32] with sg_layout=[4],
sg_data=[4] → sg_layout=[1,4], sg_data=[1,4].

Furo output at https://nigham.github.io/llvm_docs_furo/LangRef.html
- Switched theme to Furo
- Removed `:content` directives from RSTs, since Furo always has a TOC

[libc] Disable baremetal modular printf (#208576)
This reverts commit a14d084bbb1a7261d8a71c56120159abb6af330b.
Though the modular printf works as intented, we noticed a few challenges
using this feature. Without diagnostic help it is difficult to
understand which "modules" got linked in and why. Disabling this to be
the default setting until this is sorted.

[AIX] diagnose invalid feature strings on the target attribute (#208059)
Currently, Sema calls `getTargetInfo().isValidFeatureName(S)` to
validate string inputs on the `target` attribute. `PPCTargetInfo`
doesn't override the function and the base class implementation returns
true unconditionally. This results in the FE accepting invalid feature
strings on `target` attribute, and generates invalid target-feature
values in the IR.

[libc++] Enable missing allocator constructors in C++11 (#204845)
LWG2210 was a patch to N2554 (C++11) which added missing
allocator-extended constructors to various containers. When LWG2210 was
implemented, the constructors were gated with C++14. However, we
normally apply LWG issue resolutions as DRs.
This patch enables these constructors in C++11 mode too.
Fixes #204843

[orc_rt] adding a very simple CLI flags parser in (#172987)
Adds orc_rt::CommandLineParser, a small header-only option parser in
orc-rt-utils for use by orc-rt tools that need argument handling.
Features:
- Long (--name, --name=value) and short (-n, -nvalue) options.
- Short-flag clustering (e.g. -vp9999) and "--" to terminate option
parsing, with remaining tokens collected as positionals.
- Typed values, with parse failures returning an orc_rt::Error.
- printHelp() with aligned, optionally short-name-aware output.
Values are bound to caller-owned storage supplied at registration time and
reset to their defaults on each parse().
Also adds CommandLineTest.cpp to the CoreTests unittest and fixes the
indentation of the docs subdirectory guard in orc-rt/CMakeLists.txt.

[lldb] Add an MCP client and asynchronous request binding (#208371)
This PR contains the groundwork to convert lldb-mcp from a naive
forwarder into a multiplexer. This requires acting both an MCP server
and MCP client.
This PR adds a new MCP Client abstraction, a thin wrapper over
MCPTransport and MCPBinder exposing the protocol's requests as typed
asynchronous calls. BindAsync hands an incoming-request handler a Reply
it may invoke later.
This PR also makes fromJSON symmetric with toJSON for
ServerCapabilities. The former only restored supportsToolsList and
silently dropped the resources, completions and logging capabilities, so
a client parsing an initialize result never saw them.

[flang][AliasAnalysis] Add opt-in getSource memoization cache (#208319)
Add an opt-in cache to fir::AliasAnalysis that memoizes getSource()
results keyed on (value, flags). Caching is off by default and turned on
via enableSourceCache(); getSource() becomes a thin wrapper over the
uncached getSourceImpl(). The cache is a frozen snapshot with no
automatic invalidation and lives no longer than the AliasAnalysis
instance, so a client enables it only for a region in which it does not
mutate IR in a way that would change a source.
Flang's LICM enables the cache on its fir::AliasAnalysis before adding
it to the mlir::AliasAnalysis aggregate: LICM only moves operations, so
getSource()'s inputs are unchanged across the hoists, and the pass
manager drops the analysis (and its cache) after the pass.
Add a unit test covering the default-off behavior, cache fill/hit, and
that disableSourceCache() clears and bypasses the cache.

[CodeGen][BranchFolding] Add options to control common hoisting and block reordering (#205704)
The BranchFolder pass performs several independent optimizations: tail
merging, common-code hoisting, and branch optimization (which includes
basic-block reordering). Currently only tail merging is individually
controllable -- it is disabled for targets that require a structured
CFG,
because tail merging can make the CFG irreducible. Common-code hoisting
and
basic-block reordering always run whenever the pass executes.
Those two sub-phases do not change CFG edges (so they cannot affect
reducibility); they only change block layout. A target whose register
allocation is sensitive to the final block layout may need the rest of
branch folding while suppressing reordering and/or hoisting. This is a
layout / register-allocation concern, distinct from the structured-CFG
(reducibility) concern that gates tail merging.
This change makes common-code hoisting and basic-block reordering
individually controllable:
- BranchFolder gains an EnableBasicBlockReordering flag (with a
setBasicBlockReordering() setter) that gates the two block-reordering
transforms in OptimizeBlock.
- BranchFolderLegacy gains constructor parameters for both sub-phases,
and a
createBranchFolder(EnableCommonHoist, EnableBasicBlockReordering)
factory
is exposed so a target can request a safe subset from its pass pipeline.
- Two hidden command-line flags, -branch-folder-hoist-common-code and
-branch-folder-reorder-blocks, override the configured values at the
start
of OptimizeFunction (mirroring -enable-tail-merge).
Defaults enable both sub-phases, so existing behavior is unchanged for
all
in-tree targets.
New MIR tests exercise each flag via -run-pass=branch-folder.

Log Message:
-----------
[Clang] ASTUnit should use the CompilerInstance's CodeGenOptions (#195338)
Currently, `ASTUnit::LoadFromCompilerInvocation()` just calls the
constructor of `ASTUnit`, which default-constructs a `CodeGenOptions`
instance. The options from the `CompilerInstance` are never actually
saved in the `ASTUnit`. As a result, serialising the `ASTUnit` ends up
serialising the default-constructed `CodeGenOptions` rather than the
_actual_ `CodeGenOptions`.
This is problematic if you attempt to do the following:
1. Call e.g. `buildASTFromCodeWithArgs()` to build an `ASTUnit`
2. Serialise that `ASTUnit`.
3. Call e.g. `buildASTFromCodeWithArgs()` again with the exact same
arguments and add use the first `ASTUnit` as a PCH using `-include-pch`.
This causes Clang to error because the `CodeGenOptions` we deserialised
for the first `ASTUnit` (the default-constructed ones) are incompatible
with the `CodeGenOptions` implicitly created for the second TU (which
were created by the `CompilerInstance` and potentially modified due to
command-line argument parsing)... despite the fact that we basically
just attempted to build two TUs with the same arguments.
To fix this, copy the `CodeGenOptions` from the `CompilerInstance` into
the `ASTUnit`.

Reland "[ORC] Track __emutls_t definitions in IRMaterializationUnit" (#207161) (#208413)
Relands #207161, which was reverted in #207775 after the new
`clang/test/Interpreter/emulated-tls.cpp` failed on Darwin with `Symbols
not found: [ ___emutls_get_address ]`.
The `IRMaterializationUnit` fix and the test are unchanged from #207161.
What the failure exposed is that thread_locals never worked in
clang-repl on Darwin: `__emutls_get_address` is implemented in the
compiler-rt builtins static archive, and nothing links it into the
process, so process-symbol lookup cannot resolve it (on Linux it
resolves from `libgcc_s.so`).
New in this reland, per @lhames's suggestion (option 2) on the original
PR:
- `clang/lib/Interpreter/IncrementalExecutor.cpp`: on `__APPLE__`,
reference `__emutls_get_address` (forcing the builtins archive member to
be linked in) and define it as an absolute symbol in the process-symbols
JITDylib, following the precedent of the MinGW `__main` workaround in
`lli.cpp`. Scoped to the default in-process JITBuilder path only — the
host address would be meaningless for an out-of-process executor, and
custom-builder clients do their own setup.
Verified on an aarch64-darwin machine: the previously failing test now
passes, along with the rest of `clang/test/Interpreter`.
@vgvassilev @lhames — could you take a look?

[Flang][OpenMP] Added diagnostic for ORDERED THREADS SIMD inside plain SIMD region (#205723)
Fixes [#205516 ](https://github.com/llvm/llvm-project/issues/205516)
#### Problem
Per OpenMP 4.5 Sec 2.13.8 Restrictions:
> An ordered region arising from an ordered construct with both the simd
and
> threads clauses must be closely nested inside a loop SIMD region.
Flang was missing this check. `!$OMP ORDERED THREADS SIMD` inside a
standalone `!$OMP SIMD` region was accepted without diagnostic.
#### Fix
`check-omp-structure.cpp`: Added a new check in
`ChecksOnOrderedAsBlock()`. If an ORDERED directive has both SIMD and
THREADS clauses and is nested inside a standalone SIMD region (but not a
DO SIMD region), emit the following error:
`An ORDERED directive with SIMD and THREADS clauses must be closely
nested in a worksharing-loop SIMD region.`
`ordered02.f90`: Added two test cases:
Negative test: ORDERED THREADS SIMD inside !$OMP SIMD → expected error.
Positive test: ORDERED THREADS SIMD inside !$OMP DO SIMD ordered → no
error, as allowed by OpenMP 2.13.8.

[ImplicitNullChecks] Preserve debug location on FAULTING_OP (#205560)
insertFaultingInstr() built the FAULTING_OP with an empty DebugLoc,
dropping the folded memory op's source location. As a result, the
faulting load is mislabeled in the line table, giving wrong source
attribution for the very instruction that traps on a null deref. Fix by
using MI->getDebugLoc().
The original report also flagged dropped MIFlags and def renamable/
sub-register/early-clobber bits, but those are not observable:
Unpredictable is never set on loads, the register bits are never read
(FAULTING_OP is opaque until AsmPrinter), and the sub-register write is
already modeled correctly. Only the debug location is fixed here.
