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(void){

		if(h == 0 && w == 0){
			break;}
		for(i=1;i<=h;i++){
			for(j=1;j<=w;j++){
				if((i+j)%2==0){
					printf("#");
				}
				else if((i+j)%2==1){
					printf(".");
				}
			}
			printf("\n");
	}
		printf("\n");
	}
return 0;
	}
