[HLSL] Add binding attributes to resources from structs (#184731)
Add binding attributes to global variables that were created for resources embedded in structs. The binding values are based on `register` annotations and `[[vk::binding]]` attribute on the struct instance.
Fixes #182992
[lldb] Support PointerAuthAuthTraps in the expression evaluator (#187612)
Enable and test PointerAuthAuthTraps, which ensures that we trap after
an authentication failures.
[Clang] Rename OffloadArch::UNUSED to UNUSED_ to avoid macro collisions (#174528)
OffloadArch uses an enumerator named `UNUSED`, which is a very common
macro name in external codebases (e.g. Mesa defines UNUSED as an
attribute helper). If such a macro is visible when including
clang/Basic/OffloadArch.h, the preprocessor expands the token inside the
enum and breaks compilation of the installed Clang headers.
Rename the enumerator to `UNUSED_` and update all in-tree references.
This is a spelling-only change (no behavioral impact) and mirrors the
existing approach used for SM_32_ to avoid macro clashes.
[dsymutil] Preserve DWARF debug info for assembly files (#187575)
Assembly files compiled with debug info generate `DW_TAG_label entries`
with `DW_AT_low_pc` but no `DW_AT_high_pc` attributes. Without address
range information, `dsymutil` would call `addLabelLowPc()` which only
records the start address, making the compilation unit appear "empty"
with no ranges. This caused dsymutil to discard all debug information
including line tables.
This patch adds infrastructure to query symbol sizes from the debug map
and use them to reconstruct address ranges for assembly labels.

[SLP]Update values after ordered vectorization
Need to update matching between the original reduced values and their
vectorized matches after ordered reduction vectorization to avoid
a compiler crash
[MLIR][XeGPU] Fix dpas f16 output layout (#184419)
The layout propagation fails if dpas has an f16 accumulator. This fix
resolves the issue by removing the packingSize argument which seems not
valid here.
