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

```c
#include<stdio.h>

int main(){
  long long h, w;
  long long num_odd_line, odd_able_sq, ans;
  
  scanf("%lld %lld", &h, &w);
  
  if(h == 1 || w == 1){
    printf("1");
    return 0;
  }
  
  odd_able_sq = (w+1)/2;
  num_odd_line = (h+1)/2;
  
  ans = odd_able_sq * num_odd_line + (w - odd_able_sq) * (h - num_odd_line);
  printf("%lld", ans);
  
  return 0;
}
```
