Vector Add
Purpose:
Add packed 64-bit integers in a and b, and store the results in output.
Result:
A 256-bit vector that contains the result of the addition.
Example:
#include <immintrin.h>
#include <stdio.h>
int main() {
__m256i a = _mm256_set_epi64x(4, 3, 2, 1);
__m256i b = _mm256_set_epi64x(8, 7, 6, 5);
__m256i result = _mm256_add_epi64(a, b);
long long res[4];
_mm256_storeu_si256((__m256i*)res, result);
printf("%lld %lld %lld %lld\n", res[0], res[1], res[2], res[3]);
return 0;
