[NFC] [DirectX] Make DirectX codegen test `CBufferAccess/gep-ce-two-uses.ll` more strict (#169855)
Continuation of PR #169848 to address PR comments.
This PR makes the test more strict by adding CHECKs to ensure the loads
are indeed using the same or different GEPs.
[VPlan] Handle scalar VPWidenPointerInd in convertToConcreteRecipes. (#169338)
In some case, VPWidenPointerInductions become only used by scalars after
legalizeAndOptimizationInducftions was already run, for example due to
some VPlan optimizations.
Move the code to scalarize VPWidenPointerInductions to a helper and use
it if needed.
This fixes a crash after #148274 in the added test case.
Fixes https://github.com/llvm/llvm-project/issues/169780
[bolt][aarch64] Change indirect call instrumentation snippet
Indirect call instrumentation snippet uses x16 register in exit
handler to go to destination target
__bolt_instr_ind_call_handler_func:
msr nzcv, x1
ldp x0, x1, [sp], llvm#16
ldr x16, [sp], llvm#16
ldp x0, x1, [sp], llvm#16
br x16 <-----
This patch adds the instrumentation snippet by calling instrumentation
runtime library through indirect call instruction and adding the wrapper
to store/load target value and the register for original indirect instruction.
Example:
mov x16, foo

[MLIR][OpenMP] Add OpenMPToLLVMIRTranslation support for is_device_ptr
This PR adds support for the OpenMP is_device_ptr clause in the MLIR to LLVM IR translation for target regions. The is_device_ptr clause allows device pointers (allocated via OpenMP runtime APIs) to be used directly in target regions without implicit mapping.
[NFC] [DirectX] Update DirectX codegen test `CBufferAccess/gep-ce-two-uses.ll` due to changes to ReplaceConstant (#169848)
Fixes an LLVM DirectX codegen test after it broke due to #169141
The CBuffer loads and GEPs are no longer duplicated when there are two
or more accesses within the same basic block.
This PR removes the duplicate check for CBuffer load and GEP from the
original test function `@f` and adds a new test function `@g` which
places duplicate CBuffer loads into separate basic blocks.
[lld][WebAssembly] Fix SEGFAULT when importing wrapped symbol (#169656)
When wrapping a symbol `foo` via `-wrap=foo`, we create the symbol
`__wrap_foo` that replaces all mentions of `foo`. This feature was
implemented for wasm-ld in commit a5ca34e.
So far, no valid signature has been attached to the undefined symbol,
leading to a nullptr dereference in the logic for creating the import
section. This change adds the correct signature to the wrapped symbol,
enabling the generation of an import for it.
[AArch64] Use SVE for fixed-length bf16 operations with +sve-b16b16 (#169329)
This can avoid the promotion bf16 -> f32 -> bf16 round trip (or costly
expansions).
Revert "[ShrinkWrap] Modify shrink wrapping to accommodate functions terminated by no-return blocks" (#169852)
Reverts llvm/llvm-project#167548
As commented at
https://github.com/llvm/llvm-project/pull/167548#issuecomment-3587008602
this is causing miscompiles in two-stage RISC-V Clang/LLVM builds that
result in test failures on the builders.
[clang:ast] Avoid warning for unused var without assertions. (NFC) (#169822)
This PR avoids a compiler warning, which turns into an error with
`-Werror`, for a variable introduced in #169276 and only used in an
assertion (which is, thus, unused if compiled without assertions).

[ubsan] Change "Type mismatch in operation" trap reason to "Alignment, null, or object-size error" (#169752)
I originally proposed this rewording when trap reasons were introduced
in
https://github.com/llvm/llvm-project/pull/145967#discussion_r2196212344.
This was not adopted because there was a counter-proposal to split the
enum; however, that work appears to have stalled
(https://github.com/llvm/llvm-project/pull/151243). In the meantime,
there has been an additional datapoint that the current wording is
confusing to users. Thus, let's reword it now to prevent further
confusion.
[AArch64] recognise zip1/zip2 with flipped operands (#167235)
Currently, the following two snippets get treated very differently from
each other (https://godbolt.org/z/rYGj9TGz6):
```LLVM
define <8 x i8> @foo(<8 x i8> %x, <8 x i8> %y) local_unnamed_addr #0 {
entry:
%0 = shufflevector <8 x i8> %x, <8 x i8> %y, <8 x i32>
<i32 0, i32 8, i32 1, i32 9, i32 2, i32 10, i32 3, i32 11>
ret <8 x i8> %0
}
define <8 x i8> @bar(<8 x i8> %x, <8 x i8> %y) local_unnamed_addr #0 {
entry:
%0 = shufflevector <8 x i8> %x, <8 x i8> %y, <8 x i32>
<i32 8, i32 0, i32 9, i32 1, i32 10, i32 2, i32 11, i32 3>
ret <8 x i8> %0
}

[libc][darwin] add syscall numbers from macos sdk (#166354)
This PR adds support to include syscall.h from MacOS sdk by explicitly including the path to the sdk via `xcrun`.
