Yes. Unless the compiler detects that you duplicate a variable in
two parameters in the same call, you literally have *no* added
cycles, anywhere:
fun(c, c.c);
This is the only time you pay any penalty (except for passing
globals, as we now realize, since all globals can alias
themselves as parameters -- nasty).
