        * function.c (assign_parm_find_data_types): Use RECORD_OR_UNION_TYPE_P
        before testing TYPE_TRANSPARENT_AGGR.
        * calls.c (initialize_argument_information, load_register_parameters):
        Likewise.

        * calls.c (load_register_parameters): For TYPE_TRANSPARENT_AGGR
        types, use type of their first field instead of type of
        args[i].tree_value.

        * gcc.c-torture/compile/pr91001.c: New test.
