6679 * c-common.c (c_common_nodes_and_builtins): Since variants of
6680 void_type_node get built before it is given a name, we need to
6681 give those variants the name, too.
6682 (complete_array_type): We need to work with the canonical main
6683 type of the array, from which we will build the qualified version.

6685 * print-tree.c (print_node): Display canonical type information
6687 * stor-layout.c (layout_type): When we don't know the
6688 alignment of a type for which we're building an array, we end up
6689 guessing wrong, so make the type require structural equality.
6690 * tree.c (make_node_stat): When we build a new type, it is its
6692 (build_type_attribute_qual_variant): When building an attribute
6693 variant, its canonical type is the non-attribute variant. However,
6694 if the attributes are target-dependent and they differ, we need to
6695 use structural equality checks for this type.
6696 (build_qualified_type): A qualified type is not equivalent to its
6697 unqualified variant; set the canonical type appropriately.
6698 (build_distinct_type_copy): When building a distinct type from
6699 another type, the new type is its own canonical type.
6700 (build_variant_type_copy): When building a new type variant, we
6701 assume that it is equivalent to the original type.
6702 (build_pointer_type_for_mode): When building a pointer type, also
6703 build a canonical type pointer.
6704 (build_reference_type_for_mode): When building a reference type,
6705 also build a canonical type reference.
6706 (build_index_type): When we can't hash an index type (e.g.,
6707 because its maximum value is negative), the index type requires
6708 structural equality tests.
6709 (build_array_type): Build the canonical form of an array type.
6710 (build_function_type): Function types require structural equality,
6711 because they contain default arguments, attributes, etc.
6712 (build_method_type_directly): Ditto for method types.
6713 (build_offset_type): Build the canonical offset type.
6714 (build_complex_type): Build the canonical vector type.
