Given the following C code and unoptimized assembly code, your task is to generate highly optimized x86-64 assembly code.
C Code:

```c
#include <stdio.h>
int a,b,c,d;

int sister(int a,int b) {
  if(a>b) return b;
  return a;
}

int main() {
  scanf("%d %d %d %d",&a,&b,&c,&d);
  
  printf("%d\n", sister(a,b) + sister(c,d));
