--- Comment #11 from Jan Hubicka <hubicka at gcc dot gnu.org> --- I think what we need here is ability to search for vtables associated with a given anonymous namespace type and mark it as live when any of them are used (instead of taking just the default vtable). Is there a way to look them up? We will see them as a symbol, so we only need to be able to walk back to a given type.
