21374
21375         * c-common.c (c_common_nodes_and_builtins): Since variants of
21376         void_type_node get built before it is given a name, we need to
21377         give those variants the name, too.
21378         (complete_array_type): We need to work with the canonical main
21379         type of the array, from which we will build the qualified version.

21384         alignment of a type for which we're building an array, we end up

21386         * tree.c (make_node_stat): When we build a new type, it is its
21387         own canonical type.
21388         (build_type_attribute_qual_variant): When building an attribute
21389         variant, its canonical type is the non-attribute variant. However,

21391         use structural equality checks for this type.
21392         (build_qualified_type): A qualified type is not equivalent to its
21393         unqualified variant; set the canonical type appropriately.
21394         (build_distinct_type_copy): When building a distinct type from
21395         another type, the new type is its own canonical type.

21401         also build a canonical type reference.
21402         (build_index_type): When we can't hash an index type (e.g.,
21403         because its maximum value is negative), the index type requires
21404         structural equality tests.
21405         (build_array_type): Build the canonical form of an array type.
21406         (build_function_type): Function types require structural equality,
21407         because they contain default arguments, attributes, etc.

21409         (build_offset_type): Build the canonical offset type.
