------- Comment #1 from pinskia at gcc dot gnu dot org 2007-07-23 23:30 ------- Value numbering spec_28(ab) stmt = spec_28(ab) = PHI <spec_7(ab)(3)> Setting value number of spec_28(ab) to spec_7(ab)

Note the reduced testcase is missing an optimization but that is already filed as PR 32810. -- pinskia at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |NEW Ever Confirmed|0 |1 Last reconfirmed|0000-00-00 00:00:00 |2007-07-23 23:30:20 date| | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32873
