23669 * c-common.c (c_common_nodes_and_builtins): Since variants of
23670 void_type_node get built before it is given a name, we need to
23671 give those variants the name, too.

23677 * stor-layout.c (layout_type): When we don't know the
23678 alignment of a type for which we're building an array, we end up
23679 guessing wrong, so make the type require structural equality.
23680 * tree.c (make_node_stat): When we build a new type, it is its
23681 own canonical type.
23682 (build_type_attribute_qual_variant): When building an attribute
23683 variant, its canonical type is the non-attribute variant. However,
23684 if the attributes are target-dependent and they differ, we need to
23685 use structural equality checks for this type.
23686 (build_qualified_type): A qualified type is not equivalent to its
23687 unqualified variant; set the canonical type appropriately.
23688 (build_distinct_type_copy): When building a distinct type from
23689 another type, the new type is its own canonical type.
23690 (build_variant_type_copy): When building a new type variant, we
23691 assume that it is equivalent to the original type.
23692 (build_pointer_type_for_mode): When building a pointer type, also
23693 build a canonical type pointer.
23694 (build_reference_type_for_mode): When building a reference type,
23695 also build a canonical type reference.
23696 (build_index_type): When we can't hash an index type (e.g.,
23697 because its maximum value is negative), the index type requires
23698 structural equality tests.
23699 (build_array_type): Build the canonical form of an array type.
23700 (build_function_type): Function types require structural equality,
23701 because they contain default arguments, attributes, etc.
23702 (build_method_type_directly): Ditto for method types.
23703 (build_offset_type): Build the canonical offset type.
23704 (build_complex_type): Build the canonical vector type.
