Purpose:
Add packed 32-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(0x0000000100000002);
__m64 b = _m_from_int64(0x0000000300000004);
__m64 r = _m_paddd(a, b);
unsigned int out[2];
*(unsigned long long*)out = *(unsigned long long*)&r;
printf("%u %u\n", out[0], out[1]);
_m_empty();
return 0;
