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>
#include<stdlib.h>
static long long int p = 1;
static long long int b = 2;
long long int pad(int n, long long int x){
  p = (p-1)/2;
  b = (b-3)/2;
  if(n == 0) return 1;
  else if(x == 1)return 0;
  else if(x <= b+1)return pad(n-1, x-1);
  else if(x == b+2)return p+1;
  else if(x <= 2*b+2)return p+1+pad(n-1, x-b-2);
  else return 2*p+1;
}
int main(void){
  int n;
  long long int x, t;
  scanf("%d", &n);
  scanf("%lld", &x);
  for(int i=0;i<n+1;i++){
    p *= 2;
    b *= 2;
  }
  p -= 1;
  b -= 3;
  t = pad(n, x);
  printf("%lld\n", t);
  return 0;
}
```

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>
#include<stdlib.h>
static long long int p = 1;
static long long int b = 2;
long long int pad(int n, long long int x){
  p = (p-1)/2;
  b = (b-3)/2;
  if(n == 0) return 1;
  else if(x == 1)return 0;
  else if(x <= b+1)return pad(n-1, x-1);
  else if(x == b+2)return p+1;
  else if(x <= 2*b+2)return p+1+pad(n-1, x-b-2);
  else return 2*p+1;
}
int main(void){
  int n;
  long long int x, t;
  scanf("%d", &n);
  scanf("%lld", &x);
  for(int i=0;i<n+1;i++){
    p *= 2;
    b *= 2;
  }
  p -= 1;
  b -= 3;
  t = pad(n, x);
  printf("%lld\n", t);
  return 0;
}
```
