[IVDesc] Check loop-preheader for loop-legality when pass-remarks enabled (#166310)
When `-pass-remarks=loop-vectorize` is specified, the subsequent logic
is executed to display detailed debug messages even if no PreHeader
exists in the loop.
Therefore, an assert occurs when the `getLoopPreHeader()` function is
called. This commit resolves that issue.
Fixed: #165377
[AMDGPU] Introduce asyncmark/wait intrinsics
Asynchronous operations are memory transfers (usually between the global memory
and LDS) that are completed independently at an unspecified scope. A thread that
requests one or more asynchronous transfers can use async marks to track their
completion. The thread waits for each mark to be completed, which indicates that
requests initiated in program order before this mark have also completed.
For now, we implement asyncmark/wait operations on pre-GFX12 architectures that
support "LDS DMA" operations. Future work will extend support to GFX12Plus
architectures that support "true" async operations.

[libc++] Reduce the number of runs on the format_to{,n} and formatted_size benchmarks (#179922)
Testing a bunch of sizes has relatively little value. This reduces the
number of benchmarks so we can run them on a regular basis. This saves
~8 minutes when running the benchmarks.
[NFC][ELF] Fix overzealous find/replace affecting comments
Commit a94060ca0c87 ("[ELF] Pass Ctx & to Relocations") swapped the
InputSectionBase &c argument for an InputSectionBase *sec member, and so
"c." was replaced with "sec->". However, this must have done in such a
way that "Local-Exec." was transformed to "Local-Exesec->" and
"RISCV::relocateAlloc." to "RISCV::relocateAllosec->", i.e. without the
use of something like clangd, and without appropriate word boundaries in
a regex.
[AMDGPU] Fix instruction size for 64-bit literal constant operands (#180387)
`getLit64Encoding` uses a different approach to determine whether 64-bit
literal encoding is used, which caused a size mismatch between the
`MachineInstr` and the `MCInst`.
For `!isValid32BitLiteral`, it is effectively `!(isInt<32>(Val) ||
isUInt<32>(Val))`, which is `!isInt<32>(Val) && !isUInt<32>(Val)`, but
in `getLit64Encoding`, it is `!isInt<32>(Val) || !isUInt<32>(Val)`.
[MLIR][Python] Support dynamic traits in python-defined dialects (#179705)
This is a follow-up PR of #169045 and the second part of #179086.
In #179086, we added support for defining regions in Python-defined ops,
but its usefulness was quite limited because we still couldn’t mark an
op as a `Terminator` or `NoTerminator`. In this PR, we port the
`DynamicOpTrait` (introduced on the C++ side for `DynamicDialect` in
#177735) to Python, so we can dynamically attach traits to
Python-defined ops.
[LifetimeSafety] Add fixit verification with FileCheck (#180488)

[InstCombine] fold `gepi _, (srem x, y)` to `gepi _, (urem x, y)` if `y` is power-of-2 (#180148)
This PR adds a small, targeted InstCombine fold for the pattern:
```
%idx = srem i64 %x, 2^k
%p = getelementptr inbounds nuw i8, ptr %base, i64 %idx
```
When the GEP is inbounds + nuw, and the divisor is a non-zero
power-of-two constant, the signed remainder cannot produce a negative
offset without violating the inbounds/nuw constraints. In that case we
can canonicalize the index to a non-negative form and expose the common
power-of-two rewrite:
- Rewrite the GEP index from `srem %x, 2^k` to `urem %x, 2^k`
- Create a new GEP with the new index and replace the original GEP
- the `urem %x, 2^k` will further folds to `and %x (2^k-1)`
resulting the following pattern
