Macros are not an issue, as the tool would be operating on
preprocessed source code (one way or another).
As far as types go, does it really have to know anything beyond
"integer of size X" or "floating point of size X" or "pointer"? I
guess if you want to do Altivec code right it would have to know
"vector of N integers of size X". I think those can be parsed without
enormous difficulty.
Naturally you have thought about this far more than I have, and I'm
sure that you have already had much of this discussion. But having it
come up again now is pretty much unavoidable.
