high performance program (SSE4.2 intrin instruction)

标签：c   优化   gcc   

Both SSE4.1 and SSE4.2 support can be enabled via -msse4.

  1 #include <stdio.h>
  2 #include <nmmintrin.h>
  3 int main()
  4 {
  5         unsigned char pBuf[32];
  6         __m128i i;
  7         __m128i j;
  8         printf("%d\n",sizeof(__m128i));
  9         return 0;
 10 }
