Here is a better version of this (f should produce the same code as g)
int f (int r)
{
  switch (r) {
    case 1:
             return 11;
    case 2:
             return 12;
    case 3:
             return 13;
    default:
             return 20;
  }
}
int g(int r)
{
        if(r==1)
                return 11;
        else if (r==2)
                return 12;
        else if (r==3)
                return 13;
        else 
                return 30;
}
