The function called find_if and converted the iterator to an index.
The caller then had to check the index being non-zero to know if the
find succeeded.
Seems better to just do the find and distance in the caller.
Since there are no opcodes for atomic loads and stores comparing to
SelectionDAG, we add `CheckMMOIsNonAtomic` predicate immediately after
the opcode predicate to make a logical combination of them. Otherwise
when `IPM_AtomicOrderingMMO` is inserted after `IPM_GenericPredicate`,
the patterns without predicates get a higher priority as
`IPM_AtomicOrderingMMO` has higher priority than `IPM_GenericPredicate`.
This is important to preserve an order of aligned/unaligned patterns on
X86 because aligned memory operations have an additional alignment
predicate and should be checked first according to their placement in td
file.

These are unneeded even on AIX, PURE_WINDOWS, and ZOS (per #104706)
* HAVE_ERRNO_H: introduced by 1a93330ffa2ae2aa0b49461f05e6f0d51e8443f8 (2009) but unneeded.
The guarded ABI is unconditionally used by lldb.

Calling MCRegisterClass::contains with a Register does an implicit
conversion from Register to MCRegister. I think MCRegister is only
intended to be used for physical registers. We should protect this
implicit conversion by checking for physical registers first.
While I was here I removed some unnecessary parentheses from the output.
For some ABIs `update_cc_test_checks.py` is unable to generate tests
because of the mismatch between the mangled function names reported by
clang's `-asd-dump` and the function names in LLVM IR.
This patch fixes it by striping the leading underscore from the mangled
name for global functions if the data layout string says they have one.
This partially reverts commit 07ff786e39e2190449998d3af1000454dee501be.
The hunk being reverted in this patch seems to break:
tools/llvm-gsymutil/ARM_AArch64/macho-merged-funcs-dwarf.yaml
under LLVM_ENABLE_EXPENSIVE_CHECKS.
This introduces `@llvm.dx.resource.load.rawbuffer` and generalizes the
buffer load docs under DirectX/DXILResources.
This resolves the "load" parts of #106188
Currently, the more features a version has, the higher its priority is.
We are changing ACLE https://github.com/ARM-software/acle/pull/370 as
follows:
"Among any two versions, the higher priority version is determined by
identifying the highest priority feature that is specified in exactly
one of the versions, and selecting that version."
- Update pr labeler so new SPIRV files get properly labeled.
- Add distance target builtin to BuiltinsSPIRV.td.
- Update TargetBuiltins.h to account for spirv builtins.
- Update clang basic CMakeLists.txt to build spirv builtin tablegen.
- Hook up sema for SPIRV in Sema.h|cpp, SemaSPIRV.h|cpp, and
SemaChecking.cpp.
- Hookup sprv target builtins to SPIR.h|SPIR.cpp target.
- Update GBuiltin.cpp to emit spirv intrinsics when we get the expected
spirv target builtin.
Consensus was reach in this RFC to add both target builtins and pattern
matching:
https://discourse.llvm.org/t/rfc-add-targetbuiltins-for-spirv-to-support-hlsl/83329.
pattern matching will come in a separate pr this one just sets up the
groundwork to do target builtins for spirv.

[#99107](https://github.com/llvm/llvm-project/issues/99107)
When importing nested patterns, we create InsnMatcher for each pattern
and miss them if consider only the top level InsnMatcher. Iterate
PhysRegOperands instead.
Change the type of PhysRegOperands from DenseMap to SmallMapVector to
have stable generation. Also drop PhysRegInputs member from InsnMatcher
as there are no users of it.
