10543
10544         * c-common.c (c_common_nodes_and_builtins): Since variants of
10545         void_type_node get built before it is given a name, we need to
10546         give those variants the name, too.
10547         (complete_array_type): We need to work with the canonical main
10548         type of the array, from which we will build the qualified version.

10553         alignment of a type for which we're building an array, we end up

10555         * tree.c (make_node_stat): When we build a new type, it is its
10556         own canonical type.
10557         (build_type_attribute_qual_variant): When building an attribute
10558         variant, its canonical type is the non-attribute variant. However,

10560         use structural equality checks for this type.
10561         (build_qualified_type): A qualified type is not equivalent to its
10562         unqualified variant; set the canonical type appropriately.

10571         (build_index_type): When we can't hash an index type (e.g.,
10572         because its maximum value is negative), the index type requires
10573         structural equality tests.
10574         (build_array_type): Build the canonical form of an array type.
10575         (build_function_type): Function types require structural equality,
10576         because they contain default arguments, attributes, etc.
