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>

#define swap(a,b,tmp)  { tmp=a; a=b; b=tmp; }


int main(void)
{
	int a,b,c,d,temp;
	int overlap;

	// input and normalization
	scanf("%d %d %d %d",&a,&b,&c,&d);
	if (c<a)
	{
		swap(a,c,temp);
		swap(b,d,temp);
	}

	overlap=b-c;
	if (overlap>0)
	{
		temp=d-c;
		if (temp<overlap)
		{
			overlap=temp;
		}
	}
	else
	{
		overlap=0;
	}

	printf("%d\n",overlap);
	return 0;
}
