[PATCH] D87218: [builtins] Inline __paritysi2 into __paritydi2 and inline __paritydi2 into __parityti2.

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added a comment.

I think this is correct, but does their performance matter? llvm/IR/RuntimeLibcalls.def do not define them (they cannot be produced by llvm). Targets either emit popcount & 1 or detect the idiom and emit an optimized parity (x86 after PR46954)
