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>

#define LOOP 1

int calculate(int, int, char);

int main(void) 
{
	int dst, answer;
	char op = '\0';

	scanf("%d\n", &answer);

	while (LOOP) {
		scanf("\n%c", &op);

		if (op == '=') 
			break;
		else {
			scanf("\n%d", &dst);
			answer = calculate(answer, dst, op);
		}
	}
	printf("%d\n", answer);

	return 0;
}

int calculate (int src, int dst, char op) 
{
	int answer;

	switch (op) {
	case '+':
		answer = src + dst;
		break;
	case '-':
		answer = src - dst;
		break;
	case '*':
		answer = src * dst;
		break;
	case '/':
		answer = src / dst;
		break;
	}

	return answer;
}```
