8341
8342         * c-common.c (c_common_nodes_and_builtins): Since variants of
8343         void_type_node get built before it is given a name, we need to
8344         give those variants the name, too.
8345         (complete_array_type): We need to work with the canonical main
8346         type of the array, from which we will build the qualified version.

8351         alignment of a type for which we're building an array, we end up

8353         * tree.c (make_node_stat): When we build a new type, it is its
8354         own canonical type.
8355         (build_type_attribute_qual_variant): When building an attribute
8356         variant, its canonical type is the non-attribute variant. However,

8358         use structural equality checks for this type.
8359         (build_qualified_type): A qualified type is not equivalent to its
8360         unqualified variant; set the canonical type appropriately.

8362         another type, the new type is its own canonical type.

8368         also build a canonical type reference.
8369         (build_index_type): When we can't hash an index type (e.g.,
8370         because its maximum value is negative), the index type requires
8371         structural equality tests.
8372         (build_array_type): Build the canonical form of an array type.
8373         (build_function_type): Function types require structural equality,
8374         because they contain default arguments, attributes, etc.
8375         (build_method_type_directly): Ditto for method types.
8376         (build_offset_type): Build the canonical offset type.
