Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |rth at gcc dot gnu.org --- Comment #6 from Jakub Jelinek <jakub at gcc dot gnu.org> --- The problem is that RA doesn't care about predicates, only constraints, and so the constraints need to match the predicates, or it needs to be ensured in insn conditions instead.
