I am new to using SSE in C++ and i am confused by the SSE headers. I assume they are used as followed: nmmintrin.h -> SSE4.2 smmintrin.h -> SSE4.1 tmmintrin.h -> SSSE3 pmmintrin.h -> SSE3 xmmintrin.h -> SSE2 mmintrin.h -> SSE emmintrin.h -> MMX Please correct me where i am wrong, thanks in advance :)
