[PATCH] D69044: [X86] Allow up to 4 loads per inline memcmp()

[Sanjay Patel via Phabricator via llvm-commits]

spatel added a comment.

Also worth mentioning: one of the suspects for the regression in PR33914 was a trailing cmov. That's gone now*, so we might want to implement the simpler fix (expand everything to 4) and re-check perf.

*Replaced with x86 hackery:
	setae	%al
	addl	%eax, %eax
	decl	%eax
