        * tree-vrp.c (check_array_ref): Pass a location_t instead of a
        pointer. Use warning_at instead of warning.
        (search_for_addr_array): Likewise.
        (check_array_bounds): Likewise.
        (check_all_array_refs): Check that the incoming edge is not in the
        list of edges to be removed.
        (check_all_array_refs): Avoid the temporal pointer.
        (vrp_visit_cond_stmt): Fix typo.
        (simplify_switch_using_ranges): Handle the case where the switch
        index is an integer constant.

        * gcc.dg/pr36902.c: New.
