24377         (complete_array_type): We need to work with the canonical main

24386         own canonical type.
24387         (build_type_attribute_qual_variant): When building an attribute

24401         (build_index_type): When we can't hash an index type (e.g.,
24402         because its maximum value is negative), the index type requires
24403         structural equality tests.
24404         (build_array_type): Build the canonical form of an array type.
24405         (build_function_type): Function types require structural equality,
