All string functions: not surprising since recent processors have the crazy PCMPxSTRy instructions that are basically a hardware implementation of strcmp, strchr, memchr, strspn etc.
memcpy and memset use SSE on some generations, but these days are best inlined by the compiler as "rep movsb/stosb".
