 640         * stor-layout.c (layout_type): When we don't know the
 641         alignment of a type for which we're building an array, we end up
 642         guessing wrong, so make the type require structural equality.
 643         * tree.c (make_node_stat): When we build a new type, it is its
 644         own canonical type.
 645         (build_type_attribute_qual_variant): When building an attribute
 646         variant, its canonical type is the non-attribute variant. However,
 647         if the attributes are target-dependent and they differ, we need to
 648         use structural equality checks for this type.
 649         (build_qualified_type): A qualified type is not equivalent to its
 650         unqualified variant; set the canonical type appropriately.

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

 654         assume that it is equivalent to the original type.

 656         build a canonical type pointer.

 658         also build a canonical type reference.
 659         (build_index_type): When we can't hash an index type (e.g.,
 660         because its maximum value is negative), the index type requires
 661         structural equality tests.
 662         (build_array_type): Build the canonical form of an array type.
 663         (build_function_type): Function types require structural equality,
 664         because they contain default arguments, attributes, etc.
 665         (build_method_type_directly): Ditto for method types.
 666         (build_offset_type): Build the canonical offset type.

 678         parameter for verifying canonical types.
