Purpose:
Add packed 16-bit integers in "a" and "b", and store the results in "dst".
Result:
__m64
Example:
#include <mmintrin.h>
#include <stdio.h>
int main() {
__m64 a = _mm_set_pi16(1, 2, 3, 4);
__m64 b = _mm_set_pi16(10, 20, 30, 40);
__m64 r = _mm_add_pi16(a, b);
short* p = (short*)&r;
for (int i = 0; i < 4; i++)
printf("%d ", p[i]);
printf("\n");
_mm_empty();
return 0;
