--- Comment #2 from Drea Pinski <pinskia at gcc dot gnu.org> --- The question is do we reuse genmatch or go the route of using read-rtx (like Daniel's patch)? How do we share simplifications between tree and rtl? If we reuse some of genmatch, and share tree and have a mapping in some cases between the two. Like mentioned in Daniel's email about expanding say ASHIFTRT into RSHIFT_EXPR with a type (signed type) check. Or do we just have them differently.
