--- Comment #31 from Eric Botcazou <ebotcazou at gcc dot gnu.org> --- > So it appears that we have 2 classes of RISC machines, the ones supporting a > strong version of WORD_REGISTER_OPERATIONS and the others only a weak one. However I'm not sure whether exposing the distinction is really the way to go so I'm going to evaluate the pessimization that would be introduced on SPARC 64-bit by disregarding WORD_REGISTER_OPERATIONS for shift operations.
