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>
#include<stdlib.h>

int main(){
    long long a,b,c,d,h,s,t,r;
    long long e1,e2,e3,e4;
    scanf("%lld %lld %lld %lld",&a,&b,&c,&d);
    s=c;
    t=d;
    r=t%s;
    while(r!=0){
        t=s;
        s=r;
        r=t%s;
    }
    h=c*d/s;
    e1=b/c;
    e2=b/c-(a-1)/c;
    e3=b/d-(a-1)/d;
    e4=b/h-(a-1)/h;
    e1=b-a+1;
    printf("%lld\n",e1+e4-e2-e3);
