ADD TO COMPARE ADDED TO COMPARE

 Intel 64-bit (64 bits)/ SSE4.2  View official documentation
 Location: Arithmetic  >  Vector Add
Purpose:
Add packed 8-bit integers in "a" and "b", and store the results in "dst".
Result:

__m128i

Example:
#include <mmintrin.h>
#include <stdio.h>
int main() {
 __m64 a = _mm_set_pi8(1, 2, 3, 4, 5, 6, 7, 8);
 __m64 b = _mm_set_pi8(10, 20, 30, 40, 50, 60, 70, 80);
 __m64 r = _mm_add_pi8(a, b);
 char* p = (char*)&r;
 for (int i = 0; i < 8; i++)
  printf("%d ", p[i]);
  printf("\n");
  _mm_empty();

  return 0;
 }
