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 main(void)
{
   int a, i=1;

   scanf("%d",&a);

   while((a!=1)&&(a!=2)&&(a!=4)){
      if(a%2==0)
         a=a/2;
      else
         a=3*a+1;
      i++;
   }

   printf("%d\n",i+3);
   return 0;
}```
