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 cal(int *a);
int main(){
int a,b;
scanf("%d%d",&a,&b);
if((a>=1&&a<=9)&&(b>=1&&b<=9)){
a+=b;
cal(&a);
}
return 0;
}
int cal(int *a)
{
    if(*a<10){
        printf("%d\n",*a);
    }
    else{
        printf("error\n");
