M-x grep access cp/*.[ch] will show you the existing methods of access control. lookup_member would be a useful routine to set a breakpoint on and watch how it does it as well.
Thanks for the reply, this is a static analysis pass so am I wrong in thinking that most of the functionality provided in cp is non necessary? For example, the front end already took care of whether or not if an access to a member variable was legal, what about other member variables?
If that doesn't answer your question, I predict there exists another question which you'd love to ask us, but haven't, try asking that one instead (I call this the real question).
Actually, that was the real question, nothing more. I need to be able to determine what member fields of an object passed to a function are visible to that function during an optimization pass. Is there existing functionality somewhere to do that?
Thanks again for the help, Mike
