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

```c
#include <stdlib.h>
#include <string.h>
#include <math.h>
#include <stdio.h>
int compare(const void *a,const void *b){
    if(*(int *)a>*(int *)b)return 1;
    return -1;
}
int main()
{   long long h,w;
    scanf("%lld%lld",&h,&w);
    if(h==1||w==1){
        printf("1");
        return 0;
    }
    if(h*w%2==0){
        printf("%lld",h*w/2);
    }else if(h*w/2%2==0){
        printf("%lld",h*w/2+1);
    }else{
        printf("%lld",h*w/2);
    }
    return 0;
