30354 * c-common.c (c_common_nodes_and_builtins): Since variants of
30355 void_type_node get built before it is given a name, we need to
30356 give those variants the name, too.
30357 (complete_array_type): We need to work with the canonical main
30358 type of the array, from which we will build the qualified version.

30360 * print-tree.c (print_node): Display canonical type information
30362 * stor-layout.c (layout_type): When we don't know the
30363 alignment of a type for which we're building an array, we end up
30364 guessing wrong, so make the type require structural equality.
30365 * tree.c (make_node_stat): When we build a new type, it is its
30366 own canonical type.
30367 (build_type_attribute_qual_variant): When building an attribute
30368 variant, its canonical type is the non-attribute variant. However,
30369 if the attributes are target-dependent and they differ, we need to
30370 use structural equality checks for this type.
30371 (build_qualified_type): A qualified type is not equivalent to its
30372 unqualified variant; set the canonical type appropriately.
30373 (build_distinct_type_copy): When building a distinct type from
30374 another type, the new type is its own canonical type.
30375 (build_variant_type_copy): When building a new type variant, we
30376 assume that it is equivalent to the original type.
30377 (build_pointer_type_for_mode): When building a pointer type, also
30378 build a canonical type pointer.
30379 (build_reference_type_for_mode): When building a reference type,
30380 also build a canonical type reference.
30381 (build_index_type): When we can't hash an index type (e.g.,
30382 because its maximum value is negative), the index type requires
30383 structural equality tests.
30384 (build_array_type): Build the canonical form of an array type.
30385 (build_function_type): Function types require structural equality,
30386 because they contain default arguments, attributes, etc.
30387 (build_method_type_directly): Ditto for method types.
30388 (build_offset_type): Build the canonical offset type.
