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 main(void) {
	int now=0;
	int calc=0;
	char enzansi[4]="+";
	while(enzansi[0]!='=') {
		scanf("%d",&calc);
		switch(enzansi[0]) {
			case '+': now+=calc;break;
			case '-': now-=calc;break;
			case '*': now*=calc;break;
			case '/': if(calc==0)return 1;now/=calc;break;
			default: return 1;
		}
		scanf("%s",enzansi);
	}
	printf("%d\n",now);
	return 0;
}```
