30768 * print-tree.c (print_node): Display canonical type information
30770 * stor-layout.c (layout_type): When we don't know the
30771 alignment of a type for which we're building an array, we end up
30772 guessing wrong, so make the type require structural equality.
30773 * tree.c (make_node_stat): When we build a new type, it is its
30774 own canonical type.
30775 (build_type_attribute_qual_variant): When building an attribute
30776 variant, its canonical type is the non-attribute variant. However,
30777 if the attributes are target-dependent and they differ, we need to
30778 use structural equality checks for this type.
30779 (build_qualified_type): A qualified type is not equivalent to its
30780 unqualified variant; set the canonical type appropriately.
30781 (build_distinct_type_copy): When building a distinct type from
30782 another type, the new type is its own canonical type.
30783 (build_variant_type_copy): When building a new type variant, we
30784 assume that it is equivalent to the original type.
30785 (build_pointer_type_for_mode): When building a pointer type, also
30786 build a canonical type pointer.
30787 (build_reference_type_for_mode): When building a reference type,
30788 also build a canonical type reference.
30789 (build_index_type): When we can't hash an index type (e.g.,
30790 because its maximum value is negative), the index type requires
30791 structural equality tests.
30792 (build_array_type): Build the canonical form of an array type.
30793 (build_function_type): Function types require structural equality,
30794 because they contain default arguments, attributes, etc.
30795 (build_method_type_directly): Ditto for method types.
