--- Comment #3 from Jim Wilson <wilson at gcc dot gnu.org> --- Maybe the register allocator should remove clobbers of pseudos, instead of turning them into clobbers of hard register pairs. That would eliminate the ambiguity after register allocation. It is also true that we don't needs hard reg clobbers. The clobbers are only there for tracking pseudo reg subregs.
