--- Comment #25 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Why can't the middle-end/LTO handle comdat groups with some hidden and some non-hidden aliases? I don't see something inherently wrong on what the C++ FE is doing. Shouldn't we privatize the whole comdat group only if it has no exported symbols in it?
