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

```c
/*
 * ID: ALDS1_1_B
 * Problem: Greatest Common Number
 */

#include <stdio.h>

void swap(int *a, int *b)
{
    int t;
    t = *a;
    *a = *b;
    *b = t;
}

int main(void)
{
    int x, y;

    scanf("%d %d", &x, &y);

    while (x >= 1) {
        if (y > x)
            swap(&x, &y);
        x %= y;

        //printf("%d %d\n", x, y);
    }
    printf("%d\n", y);

    return 0;
}
