28612 * c-common.c (c_common_nodes_and_builtins): Since variants of
28613 void_type_node get built before it is given a name, we need to
28614 give those variants the name, too.
28615 (complete_array_type): We need to work with the canonical main
28616 type of the array, from which we will build the qualified version.

28618 * print-tree.c (print_node): Display canonical type information
28620 * stor-layout.c (layout_type): When we don't know the
28621 alignment of a type for which we're building an array, we end up
28622 guessing wrong, so make the type require structural equality.
28623 * tree.c (make_node_stat): When we build a new type, it is its
28624 own canonical type.
28625 (build_type_attribute_qual_variant): When building an attribute
28626 variant, its canonical type is the non-attribute variant. However,
28627 if the attributes are target-dependent and they differ, we need to
28628 use structural equality checks for this type.
28629 (build_qualified_type): A qualified type is not equivalent to its
28630 unqualified variant; set the canonical type appropriately.
28631 (build_distinct_type_copy): When building a distinct type from
28632 another type, the new type is its own canonical type.
28633 (build_variant_type_copy): When building a new type variant, we
28634 assume that it is equivalent to the original type.
28635 (build_pointer_type_for_mode): When building a pointer type, also
28636 build a canonical type pointer.
28637 (build_reference_type_for_mode): When building a reference type,
28638 also build a canonical type reference.
28639 (build_index_type): When we can't hash an index type (e.g.,
28640 because its maximum value is negative), the index type requires
28641 structural equality tests.
28642 (build_array_type): Build the canonical form of an array type.
28643 (build_function_type): Function types require structural equality,
28644 because they contain default arguments, attributes, etc.
28645 (build_method_type_directly): Ditto for method types.
28646 (build_offset_type): Build the canonical offset type.
28647 (build_complex_type): Build the canonical vector type.
