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 x, y,temp,step;
	
	while (1) {
		scanf("%d %d",&x,&y);
		if (x == 0 && y == 0)break;
		step = 0;
		if (x < y) {
			temp = x;
			x = y;
			y = temp;
		}
		while (y != 0) {
			x = x % y;
			temp = x;
			x = y;
			y = temp;
			step++;
		}
		printf("%d %d\n",x,step);
	}
	return 0;
}```
