30826 * c-common.c (c_common_nodes_and_builtins): Since variants of
30827 void_type_node get built before it is given a name, we need to
30828 give those variants the name, too.
30829 (complete_array_type): We need to work with the canonical main
30830 type of the array, from which we will build the qualified version.

30832 * print-tree.c (print_node): Display canonical type information
30834 * stor-layout.c (layout_type): When we don't know the
30835 alignment of a type for which we're building an array, we end up
30836 guessing wrong, so make the type require structural equality.
30837 * tree.c (make_node_stat): When we build a new type, it is its
30838 own canonical type.
30839 (build_type_attribute_qual_variant): When building an attribute
30840 variant, its canonical type is the non-attribute variant. However,
30841 if the attributes are target-dependent and they differ, we need to
30842 use structural equality checks for this type.
30843 (build_qualified_type): A qualified type is not equivalent to its
30844 unqualified variant; set the canonical type appropriately.
30845 (build_distinct_type_copy): When building a distinct type from
30846 another type, the new type is its own canonical type.
30847 (build_variant_type_copy): When building a new type variant, we
30848 assume that it is equivalent to the original type.
30849 (build_pointer_type_for_mode): When building a pointer type, also
30850 build a canonical type pointer.
30851 (build_reference_type_for_mode): When building a reference type,
30852 also build a canonical type reference.
30853 (build_index_type): When we can't hash an index type (e.g.,
30854 because its maximum value is negative), the index type requires
30855 structural equality tests.
30856 (build_array_type): Build the canonical form of an array type.
30857 (build_function_type): Function types require structural equality,
30858 because they contain default arguments, attributes, etc.
30859 (build_method_type_directly): Ditto for method types.
30860 (build_offset_type): Build the canonical offset type.
30861 (build_complex_type): Build the canonical vector type.
