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 = _m_from_int64(0x0001000200030004);
__m64 b = _m_from_int64(0x0005000600070008);
__m64 r = _m_paddw(a, b);
short out[4];
*(long long*)out = *(long long*)&r;
for(int i = 0; i < 4; i++)
printf("%d ", out[i]);
printf("\n");
_m_empty();
return 0;
