28950
28951         * c-common.c (c_common_nodes_and_builtins): Since variants of
28952         void_type_node get built before it is given a name, we need to
28953         give those variants the name, too.
28954         (complete_array_type): We need to work with the canonical main
28955         type of the array, from which we will build the qualified version.

28957         * print-tree.c (print_node): Display canonical type information
28958         for each type.
28959         * stor-layout.c (layout_type): When we don't know the
28960         alignment of a type for which we're building an array, we end up
28961         guessing wrong, so make the type require structural equality.
28962         * tree.c (make_node_stat): When we build a new type, it is its
28963         own canonical type.
28964         (build_type_attribute_qual_variant): When building an attribute
28965         variant, its canonical type is the non-attribute variant. However,
28966         if the attributes are target-dependent and they differ, we need to
28967         use structural equality checks for this type.
28968         (build_qualified_type): A qualified type is not equivalent to its
28969         unqualified variant; set the canonical type appropriately.
28970         (build_distinct_type_copy): When building a distinct type from
28971         another type, the new type is its own canonical type.
28972         (build_variant_type_copy): When building a new type variant, we
28973         assume that it is equivalent to the original type.

28975         build a canonical type pointer.

28977         also build a canonical type reference.
28978         (build_index_type): When we can't hash an index type (e.g.,
28979         because its maximum value is negative), the index type requires
28980         structural equality tests.
28981         (build_array_type): Build the canonical form of an array type.
28982         (build_function_type): Function types require structural equality,
28983         because they contain default arguments, attributes, etc.
28984         (build_method_type_directly): Ditto for method types.
28985         (build_offset_type): Build the canonical offset type.

28997         parameter for verifying canonical types.
