--- Comment #13 from Jakub Jelinek <jakub at gcc dot gnu.org> --- I think -fpatchable-function-entry support is more than 3 years old now, so I think we can't treat it like a new feature and so I don't understand defering fixing it for stage1. Doesn't the kernel use that option too for quite some time?
