9721 * print-tree.c (print_node): Display canonical type information
9723 * stor-layout.c (layout_type): When we don't know the
9724 alignment of a type for which we're building an array, we end up
9725 guessing wrong, so make the type require structural equality.
9726 * tree.c (make_node_stat): When we build a new type, it is its
9728 (build_type_attribute_qual_variant): When building an attribute
9729 variant, its canonical type is the non-attribute variant. However,
9730 if the attributes are target-dependent and they differ, we need to
9731 use structural equality checks for this type.
9732 (build_qualified_type): A qualified type is not equivalent to its
9733 unqualified variant; set the canonical type appropriately.
9734 (build_distinct_type_copy): When building a distinct type from
9735 another type, the new type is its own canonical type.
9736 (build_variant_type_copy): When building a new type variant, we
9737 assume that it is equivalent to the original type.
9738 (build_pointer_type_for_mode): When building a pointer type, also
9739 build a canonical type pointer.
9740 (build_reference_type_for_mode): When building a reference type,
9741 also build a canonical type reference.
9742 (build_index_type): When we can't hash an index type (e.g.,
9743 because its maximum value is negative), the index type requires
9744 structural equality tests.
9745 (build_array_type): Build the canonical form of an array type.
9746 (build_function_type): Function types require structural equality,
9747 because they contain default arguments, attributes, etc.
9748 (build_method_type_directly): Ditto for method types.
9749 (build_offset_type): Build the canonical offset type.
9750 (build_complex_type): Build the canonical vector type.
9751 (make_vector_type): Build the canonical vector type.

9761 parameter for verifying canonical types.
