--- Comment #16 from Jakub Jelinek <jakub at gcc dot gnu.org> --- If we go that route, I'd say it would need to be if (warning (OPT_Wpsabi, "..."))) warnedavx = true; rather than warnedavx = true; warning (OPT_Wpsabi, "..."); so that if some functions have -Wpsabi warning disabled and other enabled, if we decide to first warn on the one with the warning disabled, we warn on those that have it enabled.
