--- Comment #8 from Richard Guenther <rguenth at gcc dot gnu.org> 2011-08-01 08:49:30 UTC --- So the issue here is that enum types with non-canonical TYPE_MIN/MAX_VALUE leak from storage representation (union StateRemat) via SRA as register variables into the IL. Is that something that cannot happen for Ada because it is also careful to not use such types in storage representations?
