13332
13333         * c-common.c (c_common_nodes_and_builtins): Since variants of
13334         void_type_node get built before it is given a name, we need to
13335         give those variants the name, too.
13336         (complete_array_type): We need to work with the canonical main
13337         type of the array, from which we will build the qualified version.

13342         alignment of a type for which we're building an array, we end up

13344         * tree.c (make_node_stat): When we build a new type, it is its
13345         own canonical type.
13346         (build_type_attribute_qual_variant): When building an attribute
13347         variant, its canonical type is the non-attribute variant. However,

13349         use structural equality checks for this type.
13350         (build_qualified_type): A qualified type is not equivalent to its
13351         unqualified variant; set the canonical type appropriately.
13352         (build_distinct_type_copy): When building a distinct type from
13353         another type, the new type is its own canonical type.

13359         also build a canonical type reference.
13360         (build_index_type): When we can't hash an index type (e.g.,
13361         because its maximum value is negative), the index type requires
13362         structural equality tests.
13363         (build_array_type): Build the canonical form of an array type.
13364         (build_function_type): Function types require structural equality,
13365         because they contain default arguments, attributes, etc.

13367         (build_offset_type): Build the canonical offset type.
