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

```c
#include <stdio.h>

int main(){
  int n, i, a, sum;

  while(1){
    scanf("%d", &n);

    if(n==0){
      break;
    }

    sum=0;
    for(i=0;i<n/4;i++){
      scanf("%d", &a);
      sum += a;
    }
    
    printf("%d\n", sum);
  }
    
  return 0;
}```
