10828
10829         * c-common.c (c_common_nodes_and_builtins): Since variants of
10830         void_type_node get built before it is given a name, we need to
10831         give those variants the name, too.
10832         (complete_array_type): We need to work with the canonical main
10833         type of the array, from which we will build the qualified version.

10835         * print-tree.c (print_node): Display canonical type information
10836         for each type.
10837         * stor-layout.c (layout_type): When we don't know the
10838         alignment of a type for which we're building an array, we end up
10839         guessing wrong, so make the type require structural equality.
10840         * tree.c (make_node_stat): When we build a new type, it is its
10841         own canonical type.
10842         (build_type_attribute_qual_variant): When building an attribute
10843         variant, its canonical type is the non-attribute variant. However,
10844         if the attributes are target-dependent and they differ, we need to
10845         use structural equality checks for this type.
10846         (build_qualified_type): A qualified type is not equivalent to its
10847         unqualified variant; set the canonical type appropriately.
10848         (build_distinct_type_copy): When building a distinct type from
10849         another type, the new type is its own canonical type.
10850         (build_variant_type_copy): When building a new type variant, we
10851         assume that it is equivalent to the original type.

10853         build a canonical type pointer.

10855         also build a canonical type reference.
10856         (build_index_type): When we can't hash an index type (e.g.,
10857         because its maximum value is negative), the index type requires
10858         structural equality tests.
10859         (build_array_type): Build the canonical form of an array type.
10860         (build_function_type): Function types require structural equality,
10861         because they contain default arguments, attributes, etc.
10862         (build_method_type_directly): Ditto for method types.
10863         (build_offset_type): Build the canonical offset type.

10875         parameter for verifying canonical types.
