i want to connect gcc's front-end to my'back-end

[Stefan Strasser]

a) what makes your backend different from gcc's backend so it is worth
porting it?

there is an IR created while parsing which is simply called "Trees" and
is documented here:
http://gcc.gnu.org/onlinedocs/gccint/Trees.html#Trees

this is probably what you want.
start gdb debugger, break at function cp_finish_file and write "display
debug_tree(global_namespace)".
you should see a dump of the global namespace.

expect some work to do. gcc does some transformations while parsing
already, e.g. when calling virtual functions
