21617 * c-common.c (c_common_nodes_and_builtins): Since variants of
21618 void_type_node get built before it is given a name, we need to
21619 give those variants the name, too.
21620 (complete_array_type): We need to work with the canonical main
21621 type of the array, from which we will build the qualified version.
21622 * params.def (PARAM_VERIFY_CANONICAL_TYPES): New.
21623 * print-tree.c (print_node): Display canonical type information
21625 * stor-layout.c (layout_type): When we don't know the
21626 alignment of a type for which we're building an array, we end up
21627 guessing wrong, so make the type require structural equality.
21628 * tree.c (make_node_stat): When we build a new type, it is its
21629 own canonical type.
21630 (build_type_attribute_qual_variant): When building an attribute
21631 variant, its canonical type is the non-attribute variant. However,
21632 if the attributes are target-dependent and they differ, we need to
21633 use structural equality checks for this type.
21634 (build_qualified_type): A qualified type is not equivalent to its
21635 unqualified variant; set the canonical type appropriately.
21636 (build_distinct_type_copy): When building a distinct type from
21637 another type, the new type is its own canonical type.
21638 (build_variant_type_copy): When building a new type variant, we
21639 assume that it is equivalent to the original type.
21640 (build_pointer_type_for_mode): When building a pointer type, also
21641 build a canonical type pointer.
21642 (build_reference_type_for_mode): When building a reference type,
21643 also build a canonical type reference.
21644 (build_index_type): When we can't hash an index type (e.g.,
21645 because its maximum value is negative), the index type requires
21646 structural equality tests.
21647 (build_array_type): Build the canonical form of an array type.
21648 (build_function_type): Function types require structural equality,
21649 because they contain default arguments, attributes, etc.
21650 (build_method_type_directly): Ditto for method types.
21651 (build_offset_type): Build the canonical offset type.
