------- Additional Comments From hp at gcc dot gnu dot org 2005-04-23 15:14 ------- In response to comment #2: Any and all SET_SRC/SET_DEST mode-exceptions must be considered to be added to genpreds and genrecog as well, for possible omission of the automatically added mode checks. The sweeping statement humorousely referred to, seems to be a common delusion, shared with at least those programs. Things don't break until there's a (match_operand:P "predicate" x) where x is one of those exceptions (without genpreds/genrecog modified as per const_int). That then causes the predicate to return false.
