--- Comment #17 from Jakub Jelinek <jakub at gcc dot gnu.org> --- The really hard part will be e.g. how to mangle annotations, guess that one needs to be nth annotation of something, presumably direct base relationship could be similarly mangled as nth direct base of something, data member specification needs to mangle all 5 properties somehow, etc.
