Vector Add
Purpose:
Add 64-bit integers a and b, and store the result in output.
Result:
A 64-bit SSE2 vector containing the resuld of the addition.
Example:
#include <emmintrin.h>
#include <stdio.h>
int main() {
__m64 a = _mm_set_pi64x(1);
__m64 b = _mm_set_pi64x(5);
__m64 result = _mm_add_si64(a, b);
long long res = _mm_cvtsi64_si64(result);
printf("%lld\n", res);
return 0;
