[libc] Add posix_memalign as external entrypoint on Linux x86/ARM. (#185310)
`posix_memalign` is provided by Scudo allocator and is a part of POSIX
standard, so we can safely declare it in the `<stdlib.h>` header on
Linux systems.
[CIR][AMDGPU] Add module flags for AMDGPU target (#186081)
Upstreaming clangIR PR: https://github.com/llvm/clangir/pull/2100
This PR adds support to emit AMDGPU-specific module flags
`amdhsa_code_object_version` and `amdgpu_printf_kind` to match OGCG
behavior.
In `CIRGenModule`, the flags are stored as CIR module attributes:
`cir.amdhsa_code_object_version` (integer)
`cir.amdgpu_printf_kind` (string: "hostcall" or "buffered")
During lowering to LLVM IR (in LowerToLLVMIR.cpp), these attributes are
converted to LLVM module flags.
[XeVM] Add translation for XeVM cache-control attributes. (#181856)
Use `llvm.intr.ptr.annotation` to attach cache-control metadata to a
pointer. Each cache-control attribute produces its own annotation call;
multiple attributes are chained so every annotation sits on the same
pointer.
This approach protects the metadata across optimizations.
make: ensure .MAKE.SAVE_DOLLARS is set.
This makes it possible for macros to be set so as to work correctly
whether .MAKE.SAVE_DOLLARS is "yes" (NetBSD) or "no" (bmake).
[offload] Remove LIBOMPTARGET_SHARED_MEMORY_SIZE envar (#186231)
This commit removes the `LIBOMPTARGET_SHARED_MEMORY_SIZE` envar and
outputs a runtime warning if it is defined. Access to dynamic shared memory
should be obtained through the `dyn_groupprivate` clause (OpenMP 6.1) or
the launch arguments in liboffload kernel launch.
Exclude known failure case (#186305)
External resources does not produce same result on big-endian. Keeping
this test for regressions of the encoding scoped keeps it simple while
it doesn't affect the usage there. So just mark as XFAIL.

[RISCV] Fix crash in getShuffleCost for P-extension without V extension (#186149)
RISCVTTIImpl::getShuffleCost() crashes when querying the cost of a
reverse shufflevector on a target with the P-extension but without V/Zve
extensions. The SK_Reverse case calls
getContainerForFixedLengthVector(), which asserts hasVInstructions().
The P-extension uses fixed-width packed SIMD in GPRs, not RVV registers,
so V extension is typically not enabled.
Add an early return for P-extension fixed vectors in getShuffleCost,
consistent with the existing guards in getScalarizationOverhead,
getCastInstrCost, and getVectorInstrCost.
[RISCV] Fix crash in combinePExtTruncate for truncate(srl) without MUL/SUB (#186141)
combinePExtTruncate is called from performTRUNCATECombine when the
P-extension is enabled. It attempts to match patterns like
truncate(srl(mul/sub(...), shamt)) and combine them into P-extension
narrowing shift instructions (e.g. PNSRLI, PNSRAI).
However, after extracting the shift input operand `Op` from the SRL
node, the function unconditionally accessed Op.getOperand(0) and
Op.getOperand(1) without first verifying that Op has at least two
operands. For example, when combining:
```
truncate(v2i16
srl(v2i32
bitcast(v2i32 i64), <-- Op = bitcast, a unary op with 1 operand
BUILD_VECTOR <8, 8>))
```

[MLIR][XeGPU] Enhance Layout Propagation for broadcasting both leading dimensions and inner unit dimensions (#185583)
This PR enhances the layout propagation rules for broadcast operations.
The source layout is derived from the result layout based on the
broadcast pattern:
1. Broadcast on leading dimensions
The source layout is the slice layout of the result layout.
2. Broadcast on inner unit dimensions
The source layout matches the result layout, with sg_data and lane_data
set to 1.
3. Broadcast on both leading dimensions and inner unit dimensions
The source layout is derived by combining the above two rules.
