Purpose:
Compare packed double-precision (64-bit) floating-point elements in a and b for greater-than, and store the results in dst.
Result:
__m128d
Example:
#include <emmintrin.h>
#include <stdio.h>
int main() {
__m128d a = _mm_set_pd(3.5, 2.5);
__m128d b = _mm_set_pd(3.0, 3.5);
__m128d result = _mm_cmpgt_pd(a, b);
long long* res = (long long*)&result;
printf("Result: [0x%llx, 0x%llx]\n", res[1], res[0]);
return 0;
}Prototypes
