------- Comment #3 from pinskia at gcc dot gnu dot org 2005-12-02 03:17 ------- Hmm, this is getting harder (unless I just want to do (a^CST) == CST and (a^b) == 0. I am still deciding if I want to fix fold_binary from stoping from returning a new tree if it does nothing except for switch the order of the operands).
