[AllocToken] Enable alloc token instrumentation for size-returning functions (#168840)
Consider a newly added "malloc_span" attribute in the allocation token
instrumentation to ensure that allocation functions with the
"malloc_span" attribute are processed similarly to other memory
allocation functions.
Update the tests to demonstrate applicability to __size_returning_new.
[X86] EltsFromConsecutiveLoads - recognise reverse load patterns. (#168706)
See if we can create a vector load from the src elements in reverse and
then shuffle these back into place.
SLP will (usually) catch this in the middle-end, but there are a few
BUILD_VECTOR scalarizations etc. that appear during DAG legalization.
I did start looking at a more general permute fold, but I haven't found
any good test examples for this yet - happy to take another look if
somebody has examples.
[WebAssembly] Lower ANY_EXTEND_VECTOR_INREG (#167529)
Treat it in the same manner of zero_extend_vector_inreg and generate an
extend_low_u if possible. This is to try an prevent expensive shuffles
from being generated instead. computeKnownBitsForTargetNode has also
been updated to specify known zeros on extend_low_u.
[mlir][llvm] Handle debug record import edge cases
This commit enables the direct import of debug records by default and
fixes issues with two edge cases:
- Detect early on if the address operand is an argument list
(calling getAddress() for argument lists asserts)
- Use getAddress() to check if the address operand is null, which
means the address operand is an empty metadata node, which currently
is not supported.
- Add support for debug label records.
This is a follow-up to:

[RISCV][llvm] Select splat_vector(constant) with PLI (#168204)
Default DAG combiner combine BUILD_VECTOR with same elements to
SPLAT_VECTOR, we can just map constant splat to PLI if possible.
[CFIInserter] Turn a reachable llvm_unreachable into a report_fatal_error. (#168777)
This prevents it from being optimized out in non-asserts builds.
Update X86 test to remove REQUIRES: asserts and check for LLVM ERROR.
Add FileCheck to RISC-V test and remove UNSUPPORTED.
This is the more complete fix for #168772 and #168525.
