------- Comment #7 from amacleod at redhat dot com 2007-03-08 20:12 ------- Looking at the original testcase, the complaint is that _t_8232 and _t_3 are both used in the PHI definition of _t_7. (using mainline from march 5th) ie, _t_7(ab) = PHI <...., _t_8232, ... , _t_3, ...>
Uh, did you not put the (ab) next to the arguments, or do they really not have SSA_NAME_OCCURS_IN_ABNORMAL_PHI set on them? (They should)
I can't really read the detailed output from FRE, but it does seem to have replaced a bunch of expressions with _t_3, so that would appear to be the culprit.
It won't value number things with SSA_NAME_OCCURS_IN_ABNORMAL_PHI set, so it should never eliminate anything with them.
