Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> --- This isn't just about builtins, but any library calls introduced after IPA. E.g. -mveclibabi= calls come to my mind, if you define those functions in your library/binary and link with -flto, you'll probably get the same problem.
