Purpose:
Compare packed signed 32-bit integers in a and b for greater-than, and store the results in output.
Result:
__m256i
Example:
#include <immintrin.h>
#include <stdio.h>
int main() {
__m256i a = _mm256_set_epi32(1000, -2000, 3000, 4000, -5000, 6000, 7000, -8000);
__m256i b = _mm256_set_epi32(500, -2500, 2000, 4500, -5500, 5000, 7500, -8500);
__m256i result = _mm256_cmpgt_epi32(a, b);
int *res = (int*)&result;
for(int i = 0; i < 8; i++)
printf("%d ", res[i]);
return 0;
