------- 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.
