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>
#include <stdlib.h>

unsigned long long rec(unsigned long long l)
{
    if (l == 1)
    {
        return 1;
    }
    return 1 + 2 * rec(l/2);
}

int main()
{
    unsigned long long l;
    scanf("%llu", &l);
    printf("%llu\n", rec(l));
    return 0;
}```
