Purpose:
Compare packed signed 16-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_epi16(100, -300, 500, 150, -200, 400, 700, -50, 100, -300, 500, 150, -200, 400, 700, -50);
__m256i b = _mm256_set_epi16(50, -300, 250, 200, -250, 300, 600, -100, 50, -300, 250, 200, -250, 300, 600, -100);
__m256i result = _mm256_cmpgt_epi16(a, b);
short *res = (short*)&result;
for(int i = 0; i < 16; i++)
printf("%d ", res[i]);
return 0;
