------- Comment #10 from pinskia at gcc dot gnu dot org 2007-07-23 21:35 ------- 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)
We should not value number this PHI node, yes it is a copy but a needed copy for abnormal edges. Note the reduced testcase is missing an optimization but that is already filed as PR 32810. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32865
