Well, the only thing that is "broken" is that I had to convert it in order to Intel C++ compiler swallows it (GetRDTSC() function was initially __fastcall, that's why I have one mistake in the strlen_Traditional() function), so the final version should have one instruction less: __...
But yes, any strcmp/strlen style function that uses SSE/AVX/etc. without a buffer size parameter, must first read in smaller units until it gets to a 16/32 byte aligned address, after which it can start using SSE/AVX safely without having to worry about faulting even if it reads past ...
