--- Comment #11 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Created attachment 38672 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=38672&action=edit gcc7-pr68657.patch Untested fix. With -Werror we even suggest in diagnostic -Werror=psabi, which doesn't actually work. That said, this should have been filed as a separate PR, rather than hijacking an already fixed one.
