        * tree-ssa-dom.c (record_equivalences_from_phis): Remove
        restriction on loop depth difference.
        (record_equality): Likewise.
        (propagate_rhs_into_lhs): Likewise.  Simplify condition.

        * tree-ssa-copy.c (copy_prop_visit_phi_node): Remove
        restriction on loop depth difference.
