Purpose:
Add packed 8-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_epi8( 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64 );
__m512i b = _mm512_set1_epi8(1);
__m512i r = _mm512_add_epi8(a, b);
signed char* p = (signed char*)&r;
for (int i = 0; i < 64; i++)
printf("%d ", p[i]);
printf("\n");
return 0;
