--- Comment #11 from Jakub Jelinek <jakub at gcc dot gnu.org> --- But what exceptions are you talking about? I believe for .dwarf_frame PPC now emits the psABI mandated register numbers, and .eh_frame, being a GCC invention, simply has different register numbering, there is no reason why it would need to follow the psABI, it has it's own ABI (of course it would be better if it used the same register numbering, and it does on most targets). So what exactly you want to document and why?
