return

[Jordi]

There's a lot of methods, at least in my code that end ups returning true or 
false to tell if they were able to make a small operation in that cases what 
will be faster:

A:
bool advance()
{
  bool result=true;
  if (current_frame== max_frame)
    if (cyclic)
      current_frame=0;
    else
      result=false;
  else
    ++current_frame;  
  return result;
}

or

B:
bool advance()
{
  if (current_frame== max_frame)
    if (cyclic)
      current_frame=0;
    else
      return false;
  else
    ++current_frame;  
  return result;
}

In case A a bool has to be allocated in that method but gcc is supposed to 
optimize that case.
In case B the bool is get ridden and gcc is supposed to not be able to 
optimize that well....

What's faster A or B?
