1559
1560         * c-common.c(c_common_nodes_and_builtins): Since variants of
1561         void_type_node get built before it is given a name, we need to
1562         give those variants the name, too.
1563         (complete_array_type): We need to work with the canonical main
1564         type of the array, from which we will build the qualified version.
1565         * params.def (PARAM_VERIFY_CANONICAL_TYPES): New.
1566         * print-tree.c (print_node): Display canonical type information
1567         for each type.
1568         * stor-layout.c (layout_type): When we don't know the
1569         alignment of a type for which we're building an array, we end up
1570         guessing wrong, so make the type require structural equality.
1571         * tree.c (make_node_stat): When we build a new type, it is its
1572         own canonical type.
1573         (build_type_attribute_qual_variant): When building an attribute
1574         variant, its canonical type is the non-attribute variant. However,
1575         if the attributes are target-dependent and they differ, we need to
1576         use structural equality checks for this type.
1577         (build_qualified_type): A qualified type is not equivalent to its
1578         unqualified variant; set the canonical type appropriately.
1579         (build_distinct_type_copy): When building a distinct type from
1580         another type, the new type is its own canonical type.

1582         assume that it is equivalent to the original type.

1584         build a canonical type pointer.

1586         also build a canonical type reference.
1587         (build_index_type): When we can't hash an index type (e.g.,
1588         because its maximum value is negative), the index type requires
1589         structural equality tests.
1590         (build_array_type): Build the canonical form of an array type.
1591         (build_function_type): Function types require structural equality,
1592         because they contain default arguments, attributes, etc.
1593         (build_method_type_directly): Ditto for method types.
1594         (build_offset_type): Build the canonical offset type.
