11155
11156         * c-common.c (c_common_nodes_and_builtins): Since variants of
11157         void_type_node get built before it is given a name, we need to
11158         give those variants the name, too.
11159         (complete_array_type): We need to work with the canonical main
11160         type of the array, from which we will build the qualified version.

11162         * print-tree.c (print_node): Display canonical type information
11163         for each type.

11165         alignment of a type for which we're building an array, we end up
11166         guessing wrong, so make the type require structural equality.
11167         * tree.c (make_node_stat): When we build a new type, it is its
11168         own canonical type.
11169         (build_type_attribute_qual_variant): When building an attribute
11170         variant, its canonical type is the non-attribute variant. However,
11171         if the attributes are target-dependent and they differ, we need to
11172         use structural equality checks for this type.
11173         (build_qualified_type): A qualified type is not equivalent to its
11174         unqualified variant; set the canonical type appropriately.
11175         (build_distinct_type_copy): When building a distinct type from
11176         another type, the new type is its own canonical type.
11177         (build_variant_type_copy): When building a new type variant, we
11178         assume that it is equivalent to the original type.

11182         also build a canonical type reference.
11183         (build_index_type): When we can't hash an index type (e.g.,
11184         because its maximum value is negative), the index type requires
11185         structural equality tests.
11186         (build_array_type): Build the canonical form of an array type.
11187         (build_function_type): Function types require structural equality,
11188         because they contain default arguments, attributes, etc.
11189         (build_method_type_directly): Ditto for method types.
11190         (build_offset_type): Build the canonical offset type.
