--- Comment #3 from Jorn Wolfgang Rennecke <amylaar at gcc dot gnu.org> 2012-03-12 13:25:38 UTC --- (In reply to comment #1) > Why are there two incompatible representations of register classes in the > first > place, i.e. enum reg_class and reg_class_t? enum reg_class is a target specific type, thus it is not suitable for target hooks, which should have a type that is independent of any particular target.
