Purpose:
Add packed 64-bit integers in "a" and "b", and store the results in "dst".
Result:
__m512i
Example:
#include <immintrin.h>
#include <stdio.h>
int main() {
__m512i a = _mm512_set_epi64(1, 2, 3, 4, 5, 6, 7, 8);
__m512i b = _mm512_set1_epi64(10);
__m512i r = _mm512_add_epi64(a, b);
long long* p = (long long*)&r;
for (int i = 0; i < 8; i++)
printf("%lld ", p[i]);
printf("\n");
return 0;
