[clang-tidy] Fix false positive for constrained template parameters in `cppcoreguidelines-missing-std-forward` (#182038)
Explicit object parameters with a type constraint are skipped to avoid
false positives. They are technically still forwarding references per
[temp.deduct.call], but rarely intended to be perfectly forwarded.
Fixes #180362
[clangd] Disable PCH for libs that use gRPC (#185185)
gRPC adds -pthread, which is incompatible with PCH without it. At some
point, we probably should generally switch from -lpthread to -pthread,
but until then, disable PCH for affected targets.
Fixes https://github.com/llvm/llvm-project/issues/184759.
[CIR] Split CIR_UnaryOp into individual operations
Split the monolithic cir.unary operation (which dispatched on a
UnaryOpKind enum) into five separate operations: cir.inc, cir.dec,
cir.plus, cir.minus, and cir.not.
This follows the same pattern used when cir.binop was split into
individual binary operations (AddOp, SubOp, etc.).
Changes:
- Add CIR_UnaryOpInterface with getInput()/getResult() methods
- Add CIR_UnaryOp and CIR_UnaryOpWithOverflowFlag base classes
- Define IncOp, DecOp, PlusOp, MinusOp, NotOp with per-op folds
- Replace createUnaryOp() with createInc/Dec/Plus/Minus/Not builders
- Split LLVM lowering into five separate patterns
- Split LoweringPrepare complex-type handling into five handlers
- Update CIRCanonicalize and CIRSimplify for new op types
- Update all codegen files to use bool params instead of UnaryOpKind
- Remove CIR_UnaryOpKind enum and old CIR_UnaryOp definition

[Clang][AArch64] Reorganize tests for `vceqz` intrinsics (NFC) (#185090)
Group related `vceqz_*` and `vceqzd_*` tests together for consistency
and readability. Add a comment documenting the scalar variants that are
not currently covered.
No functional change.
Follow-up to #184893.
[CIR] Add Commutative/Idempotent traits to binary ops
Add missing MLIR traits to CIR binary operations, matching the arith
dialect conventions:
- AndOp, OrOp: Commutative, Idempotent (fixes FIXME)
- AddOp, MulOp, XorOp, MaxOp: Commutative
Add these ops to the CIRCanonicalize pass op list so trait-based
folding is exercised by applyOpPatternsGreedily.
Update testFloatingPointBinOps in binop.cpp to use computed values,
preventing DCE of the now-canonicalized ops.
[lldb][PlatformDarwin][test] Add unit-test for LocateExecutableScriptingResourcesFromDSYM (#185057)
Depends on:
* https://github.com/llvm/llvm-project/pull/185056
Adds test unit-test for
`PlatformDarwin::LocateExecutableScriptingResourcesFromDSYM`. I had to
mock the `ScriptInterpreter` because the function internally uses the
`ScriptInterpreterPython` to check for reserved words in file names. But
linking the `ScriptInterpreterPython` was quite the undertaking, which I
think we could pull off, but required more churn that I had hoped.
Mocking it seemed pretty low-cost so I resorted to doing that instead.
Test-cases aren't very elaborate yet. It just has a basic assertion that
we locate the Python file within the dSYM. Mostly I set up
infrastructure for future test-cases.
libclc: Avoid duplicated get_local_size/get_global_size functions (#185166)
Move opencl handling on top of clc into opencl generic, delete
amdgpu implementations in opencl.
[Analysis] isTriviallyVectorizable - add Intrinsic::clmul along with vectorisation tests (#180014)
This patch adds a case in isTriviallyVectorizable in llvm/lib/Analysis/VectorUtils.cpp for Intrinsic::clmul.
Fixes #179106
