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 ABS(int a){
	return a >= 0 ? a : -a;
}

int GCD(int a, int b){
	if(b == 0){
		return a;
	}
	else{
		return GCD(b, a % b);
	}
}

int main(){
	int A, B, C, D, H, W, g;
	scanf("%d%d%d%d", &A, &B, &C, &D);
	H = ABS(A - C);
	W = ABS(B - D);
	g = GCD(H, W);
	H /= g;
	W /= g;
	printf("%d\n", g * (H + W - 1));
	return 0;
}```
