--- Comment #5 from Richard Biener <rguenth at gcc dot gnu.org> --- Indeed: (gdb) p debug_generic_expr (t1) OBJ_TYPE_REF(_7;&objc_super->0) $1 = void (gdb) p debug_generic_expr (t2) OBJ_TYPE_REF(_7;&objc_super->0) $2 = void I think dispatching to compare_ssa_name is premature optimization - just use compare_operand?
