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() {
    int a,i,sum=0;
    scanf("%d",&a);
    for(i=1;i<=a;i++){
        sum+=i;
    }
    printf("%d\n",sum);
    return 0;
}
```

Unoptimized Assembly Code:
