[DAG] isKnownNeverZero: Add DemandedElts handling for ROTL/ROTR/BITREVERSE/BSWAP/CTPOP/ABS (#184033)

Add DemandedElts handling for ROTL/ROTR/BITREVERSE/BSWAP/CTPOP/ABS in SelectionDAG::isKnownNeverZero

Fixes #183040

libclc: Move get_global_id into clc

libclc: Use enqueued local size to implement get_global_id

[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

[CIR][NFC] Merge try-catch-tmp with try-catch test file (#185123)

Merge try-catch-tmp.cpp the with try-catch test file

[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.

libclc: Add amdgpu wait_group_events

[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: Fix amdgpu get_enqueued_local_size (#185171)

This should not be the same as get_local_size

Merge branch 'main' into users/arsenm/libclc/fix-amdgpu-get-enqueued-local-size

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

Fix ptx build

Use __clc_get_global_size

Use v5 implementation

amdgpu implementations in opencl.

libclc: Implement get_global_linear_id and get_local_linear_id (#184800)

[WebKit checkers] Disallow operator delete in a trivial context. (#185122)

This PR changes the "trivial function analysis" to disallow `operator
delete` in a "trival" or "nodelete" function or statement. Without this,
the delete operator could deallocate memory for a reference counted
objects, etc...

Use __clc_get_enqueued_local_size

[libc++] Fix std::variant comparators not working on recursive instantiations (#182238)

We currently have an instantiation cycle in `variant`'s comparison
operators. This patch fixes that by replacing a `decltype(auto)` with an
explicit return type, removing the requirement to instantiate the
function in order to know the return type.

Fixes #182232

libclc: Avoid duplicated get_local_size/get_global_size functions

[CMake][LLVM] Align CMAKE_EXPORT_COMPILE_COMMANDS from 1 to ON (#184971)

ON/OFF are more conventional in the project for boolean CMake variables.

[libunwind][PAC] Defang ptrauth's PC in valid CFI range abort

It turns out making the CFI check a release mode abort causes many,
if not the majority, of JITs to fail during unwinding as they do not
set up CFI sections for their generated code. As a result any JITs
that do nominally support unwinding (and catching) through their JIT
or assembly frames trip this abort.

[libc++] Don't double-wrap iterators when bounded iterators are used (#182264)

There is no reason to double-wrap iterators, since we can already
achieve anything we want within `__bounded_iter`itself.

This is technically ABI breaking, but people using bounded iterators
shouldn't require ABI stability currently.

Fixes #178521
