https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78540 --- Comment #9 from Jakub Jelinek --- Created attachment 40342 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=40342&action=edit gcc6-pr78540-test.patch Oops, forgot in 6.x and earlier -Wno-psabi doesn't work for ppc*. Does this fix the issue? If so, I'll commit it soon (to 6.x only, trunk doesn't need it).
