24374 * c-common.c (c_common_nodes_and_builtins): Since variants of
24375 void_type_node get built before it is given a name, we need to
24376 give those variants the name, too.

24382 * stor-layout.c (layout_type): When we don't know the
24383 alignment of a type for which we're building an array, we end up
24384 guessing wrong, so make the type require structural equality.
24385 * tree.c (make_node_stat): When we build a new type, it is its
24386 own canonical type.
24387 (build_type_attribute_qual_variant): When building an attribute
24388 variant, its canonical type is the non-attribute variant. However,
24389 if the attributes are target-dependent and they differ, we need to
24390 use structural equality checks for this type.
24391 (build_qualified_type): A qualified type is not equivalent to its
24392 unqualified variant; set the canonical type appropriately.
24393 (build_distinct_type_copy): When building a distinct type from
24394 another type, the new type is its own canonical type.
24395 (build_variant_type_copy): When building a new type variant, we
24396 assume that it is equivalent to the original type.
24397 (build_pointer_type_for_mode): When building a pointer type, also
24398 build a canonical type pointer.
24399 (build_reference_type_for_mode): When building a reference type,
24400 also build a canonical type reference.
24401 (build_index_type): When we can't hash an index type (e.g.,
24402 because its maximum value is negative), the index type requires
24403 structural equality tests.
24404 (build_array_type): Build the canonical form of an array type.
24405 (build_function_type): Function types require structural equality,
24406 because they contain default arguments, attributes, etc.
24407 (build_method_type_directly): Ditto for method types.
