21356
21357         * c-common.c (c_common_nodes_and_builtins): Since variants of
21358         void_type_node get built before it is given a name, we need to
21359         give those variants the name, too.
21360         (complete_array_type): We need to work with the canonical main
21361         type of the array, from which we will build the qualified version.

21366         alignment of a type for which we're building an array, we end up
21367         guessing wrong, so make the type require structural equality.
21368         * tree.c (make_node_stat): When we build a new type, it is its
21369         own canonical type.
21370         (build_type_attribute_qual_variant): When building an attribute
21371         variant, its canonical type is the non-attribute variant. However,
21372         if the attributes are target-dependent and they differ, we need to
21373         use structural equality checks for this type.
21374         (build_qualified_type): A qualified type is not equivalent to its
21375         unqualified variant; set the canonical type appropriately.
21376         (build_distinct_type_copy): When building a distinct type from
21377         another type, the new type is its own canonical type.

21383         also build a canonical type reference.
21384         (build_index_type): When we can't hash an index type (e.g.,
21385         because its maximum value is negative), the index type requires
21386         structural equality tests.
21387         (build_array_type): Build the canonical form of an array type.
21388         (build_function_type): Function types require structural equality,
21389         because they contain default arguments, attributes, etc.
21390         (build_method_type_directly): Ditto for method types.
21391         (build_offset_type): Build the canonical offset type.
