Anyway, what's the supposed advantage of *(volatile *) vs. using a real volatile object? That you can access that same object in a non-volatile way?
That's my understanding. That way accesses where you don't care about volatility may be optimised.
For instance, in cases where there are already other things controlling visibility (as are needed for atomic increment, for example) you don't need to make the access itself volatile.
