--- Comment #5 from Andrew Pinski <pinskia at gcc dot gnu.org> --- Setting value number of _11 to wm_8 (changed) Making available beyond BB8 _11 for value wm_8 Value numbering stmt = if (_11 == 0) So when insert_predicates_for_cond does a vn_valueize of wm_8 (due the path handling of `(a | b) == 0`), we get back _11 and then go into an infinite loop.
