9717         give those variants the name, too.
9718         (complete_array_type): We need to work with the canonical main
9719         type of the array, from which we will build the qualified version.

9721         * print-tree.c (print_node): Display canonical type information
9722         for each type.
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
9727         own canonical type.
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.

9735         another type, the new type is its own canonical type.

9737         assume that it is equivalent to the original type.

9739         build a canonical type pointer.

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.

9761         parameter for verifying canonical types.
