[Bug middle-end/23673] fold does not fold (a^b) != 0 to a != b

[pinskia at gcc dot gnu dot org]

------- 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).
