--- Comment #28 from Eric Botcazou <ebotcazou at gcc dot gnu.org> --- > Well, at least at this point in GCC 7 development the fewer architectures we > change the better. Sure, but by changing the middle-end, you change all the architectures at once and may break a fair number of them in the process. At this point I'd lean towards Bernd's position and revert again the get_dynamic_stack_size change, since it relies on the very questionable settings of init_emit.
