1564
1565         * c-common.c(c_common_nodes_and_builtins): Since variants of
1566         void_type_node get built before it is given a name, we need to
1567         give those variants the name, too.
1568         (complete_array_type): We need to work with the canonical main
1569         type of the array, from which we will build the qualified version.

1571         * print-tree.c (print_node): Display canonical type information
1572         for each type.

1574         alignment of a type for which we're building an array, we end up
1575         guessing wrong, so make the type require structural equality.
1576         * tree.c (make_node_stat): When we build a new type, it is its
1577         own canonical type.
1578         (build_type_attribute_qual_variant): When building an attribute
1579         variant, its canonical type is the non-attribute variant. However,

1581         use structural equality checks for this type.
1582         (build_qualified_type): A qualified type is not equivalent to its
1583         unqualified variant; set the canonical type appropriately.
1584         (build_distinct_type_copy): When building a distinct type from
1585         another type, the new type is its own canonical type.

1589         build a canonical type pointer.

1591         also build a canonical type reference.
1592         (build_index_type): When we can't hash an index type (e.g.,
1593         because its maximum value is negative), the index type requires
1594         structural equality tests.
1595         (build_array_type): Build the canonical form of an array type.
1596         (build_function_type): Function types require structural equality,
1597         because they contain default arguments, attributes, etc.
1598         (build_method_type_directly): Ditto for method types.
1599         (build_offset_type): Build the canonical offset type.
