How does the information record look currently? Our RTTIs aren't 100% 
compatible anyway, so I wouldn't mind if we add needed fields for other 
platforms. Of course we'd first need to know whether any other platform 
has such needs...
At least for m68k I can say that register index and stack offset should 
be enough.
