[X86] Remove extra MOV after widening atomic store
This change adds patterns to optimize out an extra MOV present after
widening the atomic store. Covers <2 x i8> (SSE4.1+), <2 x i16>,
<4 x i8>, <2 x i32>, <2 x float>, <4 x i16>, <2 x ptr addrspace(270)>.
[flang][openacc] allow duplicate data sharing clauses (#197019)
This PR allows duplicate OpenACC `private` and `firstprivate` clauses.
While maintaining the restriction on `reduction` clauses.
[flang][cuda] Honor !dir$ ignore_tkr(m) under -gpu=mem:{unified,managed} (#197518)
A device-typed dummy with `!dir$ ignore_tkr(m)` is meant to be an
overload discriminator (only selected for actuals with an explicit
`device/managed/unified` attribute). Skip the host->device relaxation in
AreCompatibleCUDADataAttrs when `IgnoreTKR::Managed` is set so
unattributed host actuals no longer bind to such a dummy.
Also document the §3.2.3 matching distance table next to
GetMatchingDistance and add LIT tests for the full Table 2 grid
and the ignore_tkr(m) carve-out.
security/nss: drop binutils on powerpc64le
LLVM's integrated assembler rejects .set-aliased symbols inside memory
operand parentheses, e.g. `std 31,-8(SP)` with `.set SP, 1`. Replace
the SP alias with its numeric value (r1) in the memory operands so the
IAS accepts them. Other uses of SP outside parentheses are fine.
[AMDGPU] Validate forced lit() immediate (#196623)
Right now it takes validation path of an inline constant if fits
even though it is forced to literal encoding.
[MIR] Serialize/Deserialize MachineInstr::LRSplit attribute
The LRSplit MachineInstr flag is set by SplitKit on copies inserted for
live-range splitting.
Until now the flag had no MIR-text representation.
This patch fixes that so that it gets easier to reproduce/capture issues
that involves SplitKit.
Round-trip coverage in
llvm/test/CodeGen/MIR/AMDGPU/lr-split-flag.mir.
[AMDGPU][test] Use mir test for regalloc issue
Use the newly introduced split-from flag to produce a more robust test case
for the hoistSpillInsideBB live-range update issue.

[MIR] Save internal VirtRegMap state in MIR
Adds two optional fields to the per-vreg YAML record so MIR tests can
express VirtRegMap state that previously had no representation:
registers:
- { id: 1, class: vgpr_32, split-from: '%0', assigned-phys: '$vgpr5' }
Testing passes that consume sibling-register information (e.g.
InlineSpiller) requires constructing a VirtRegMap with split
relationships from a MIR test, which implies triggering live-range
splitting at minimum and make reproducers unnecessarily complicated.
So this change introduces a mechanism to serialize/deserialize the state
of the VirtRegMap pass.
Mechanism:
- For serialization:
- MIRPrinter emits the new fields only when the VirtRegMap is available.

Reject target map iterators without captures
Reject target map iterators until the follow-up capture-binding
representation is added since currently map_iterated on omp.target
only represents the dynamic map list and does not consider the
target-region arguments required by IsolatedFromAbove.

Simplify map iterator clause assembly
- Split MLIR map syntax into separate map_entries(...) and map_iterated(...),
removing the custom MapEntryList parser/printer.
- Moved omp.target map_iterated out of TargetOpRegion
- it now prints before the target region instead of as map_iterated_entries(...) after the region.
- Renamed LLVMIR TODO helper to clause-style checkMap.
- Added DeclareMapperInfoOp builder from DeclareMapperInfoOperands
and updated Flang call sites so they do not need to spell out newly
added operands..
