Purpose:
Compare packed unsigned 8-bit integers in "a" and "b", and store packed minimum values in "dst".
Result:
__m512i
Example:
#include <immintrin.h>
#include <stdio.h>
int main() {
__m512i a = _mm512_set_epi8(255, 200, 150, 100, 50, 0, 25, 10, 30, 60, 90, 120, 150, 180, 210, 240, 100, 120, 140, 160, 180, 200, 220, 240, 20, 40, 60, 80, 100, 120, 140, 160, 180, 200, 220, 240, 250, 255, 100, 90, 80, 70, 60, 50, 40, 30, 20, 10, 255, 200, 150, 100, 50, 0, 25, 10, 255, 200, 150, 100, 50, 0, 25, 10);
