22400 * c-common.c (c_common_nodes_and_builtins): Since variants of
22401 void_type_node get built before it is given a name, we need to
22402 give those variants the name, too.
22403 (complete_array_type): We need to work with the canonical main
22404 type of the array, from which we will build the qualified version.

22408 * stor-layout.c (layout_type): When we don't know the
22409 alignment of a type for which we're building an array, we end up
22410 guessing wrong, so make the type require structural equality.
22411 * tree.c (make_node_stat): When we build a new type, it is its
22412 own canonical type.
22413 (build_type_attribute_qual_variant): When building an attribute
22414 variant, its canonical type is the non-attribute variant. However,
22415 if the attributes are target-dependent and they differ, we need to
22416 use structural equality checks for this type.
22417 (build_qualified_type): A qualified type is not equivalent to its
22418 unqualified variant; set the canonical type appropriately.
22419 (build_distinct_type_copy): When building a distinct type from
22420 another type, the new type is its own canonical type.
22421 (build_variant_type_copy): When building a new type variant, we
22422 assume that it is equivalent to the original type.
22423 (build_pointer_type_for_mode): When building a pointer type, also
22424 build a canonical type pointer.
22425 (build_reference_type_for_mode): When building a reference type,
22426 also build a canonical type reference.
22427 (build_index_type): When we can't hash an index type (e.g.,
22428 because its maximum value is negative), the index type requires
22429 structural equality tests.
22430 (build_array_type): Build the canonical form of an array type.
22431 (build_function_type): Function types require structural equality,
22432 because they contain default arguments, attributes, etc.
22433 (build_method_type_directly): Ditto for method types.
22434 (build_offset_type): Build the canonical offset type.
