That project really covered a very small amount of the necessary work;
I'd be happy to have another student continue with it. Things not yet
implemented include constructors, destructors, member pointers,
derived-to-base conversions that hop virtual bases, RTTI, dynamic_cast,
virtual calls, vf-table emission, vb-table emission, and I'm probably
forgetting a number of other things. There's also a lot still to be done
with mangling, IIRC.
vf-table layout would be a challenging project, but I don't think it's
unreasonable as a full-summer thing for a student with previous
clang experience. It also nicely breaks down into sub-projects,
since you can start with the simplest cases (single non-virtual
inheritance, no thunks) and gradually add complexity.
