Purpose:
Add packed double-precision (64-bit) floating-point elements in "a" and "b", and store the results in "dst".
Result:
__m512d
Example:
#include <immintrin.h>
#include <stdio.h>
int main() {
__m512d a = _mm512_set_pd(1, 2, 3, 4, 5, 6, 7, 8);
__m512d b = _mm512_set1_pd(0.5);
__m512d r = _mm512_add_pd(a, b);
double* p = (double*)&r;
for (int i = 0; i < 8; i++)
printf("%.1f ", p[i]);
printf("\n");
return 0;
