9563         for each type.
9564         * stor-layout.c (layout_type): When we don't know the
9565         alignment of a type for which we're building an array, we end up
9566         guessing wrong, so make the type require structural equality.
9567         * tree.c (make_node_stat): When we build a new type, it is its
9568         own canonical type.
9569         (build_type_attribute_qual_variant): When building an attribute
9570         variant, its canonical type is the non-attribute variant. However,
9571         if the attributes are target-dependent and they differ, we need to
9572         use structural equality checks for this type.
9573         (build_qualified_type): A qualified type is not equivalent to its
9574         unqualified variant; set the canonical type appropriately.

9576         another type, the new type is its own canonical type.

9578         assume that it is equivalent to the original type.

9580         build a canonical type pointer.

9582         also build a canonical type reference.
9583         (build_index_type): When we can't hash an index type (e.g.,
9584         because its maximum value is negative), the index type requires
9585         structural equality tests.
9586         (build_array_type): Build the canonical form of an array type.
9587         (build_function_type): Function types require structural equality,
9588         because they contain default arguments, attributes, etc.
9589         (build_method_type_directly): Ditto for method types.
9590         (build_offset_type): Build the canonical offset type.

9602         parameter for verifying canonical types.
