23638 * c-common.c (c_common_nodes_and_builtins): Since variants of
23639 void_type_node get built before it is given a name, we need to
23640 give those variants the name, too.
23641 (complete_array_type): We need to work with the canonical main
23642 type of the array, from which we will build the qualified version.
23643 * params.def (PARAM_VERIFY_CANONICAL_TYPES): New.
23644 * print-tree.c (print_node): Display canonical type information
23646 * stor-layout.c (layout_type): When we don't know the
23647 alignment of a type for which we're building an array, we end up
23648 guessing wrong, so make the type require structural equality.
23649 * tree.c (make_node_stat): When we build a new type, it is its
23650 own canonical type.
23651 (build_type_attribute_qual_variant): When building an attribute
23652 variant, its canonical type is the non-attribute variant. However,
23653 if the attributes are target-dependent and they differ, we need to
23654 use structural equality checks for this type.
23655 (build_qualified_type): A qualified type is not equivalent to its
23656 unqualified variant; set the canonical type appropriately.
23657 (build_distinct_type_copy): When building a distinct type from
23658 another type, the new type is its own canonical type.
23659 (build_variant_type_copy): When building a new type variant, we
23660 assume that it is equivalent to the original type.
23661 (build_pointer_type_for_mode): When building a pointer type, also
23662 build a canonical type pointer.
23663 (build_reference_type_for_mode): When building a reference type,
23664 also build a canonical type reference.
23665 (build_index_type): When we can't hash an index type (e.g.,
23666 because its maximum value is negative), the index type requires
23667 structural equality tests.
23668 (build_array_type): Build the canonical form of an array type.
23669 (build_function_type): Function types require structural equality,
23670 because they contain default arguments, attributes, etc.
23671 (build_method_type_directly): Ditto for method types.
23672 (build_offset_type): Build the canonical offset type.
