22418 * c-common.c (c_common_nodes_and_builtins): Since variants of
22419 void_type_node get built before it is given a name, we need to
22420 give those variants the name, too.
22421 (complete_array_type): We need to work with the canonical main
22422 type of the array, from which we will build the qualified version.

22426 * stor-layout.c (layout_type): When we don't know the
22427 alignment of a type for which we're building an array, we end up
22428 guessing wrong, so make the type require structural equality.
22429 * tree.c (make_node_stat): When we build a new type, it is its
22430 own canonical type.
22431 (build_type_attribute_qual_variant): When building an attribute
22432 variant, its canonical type is the non-attribute variant. However,
22433 if the attributes are target-dependent and they differ, we need to
22434 use structural equality checks for this type.
22435 (build_qualified_type): A qualified type is not equivalent to its
22436 unqualified variant; set the canonical type appropriately.
22437 (build_distinct_type_copy): When building a distinct type from
22438 another type, the new type is its own canonical type.
22439 (build_variant_type_copy): When building a new type variant, we
22440 assume that it is equivalent to the original type.
22441 (build_pointer_type_for_mode): When building a pointer type, also
22442 build a canonical type pointer.
22443 (build_reference_type_for_mode): When building a reference type,
22444 also build a canonical type reference.
22445 (build_index_type): When we can't hash an index type (e.g.,
22446 because its maximum value is negative), the index type requires
22447 structural equality tests.
22448 (build_array_type): Build the canonical form of an array type.
22449 (build_function_type): Function types require structural equality,
22450 because they contain default arguments, attributes, etc.
22451 (build_method_type_directly): Ditto for method types.
22452 (build_offset_type): Build the canonical offset type.
