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(void)
{
	int n;
	int f;
	int x;
	int i;
	
	while (scanf("%d", &n), n != -1){
		f = 0;
		for (i = 20; i >= 0; i -= 2){
			x = n >> i & 3;
			if (x > 0 || i == 0){
				f = 1;
			}
			if (f){
				printf("%d", x);
			}
		}
		printf("\n");
	}
	
	return (0);
}```
