10821
10822         * c-common.c (c_common_nodes_and_builtins): Since variants of
10823         void_type_node get built before it is given a name, we need to
10824         give those variants the name, too.
10825         (complete_array_type): We need to work with the canonical main
10826         type of the array, from which we will build the qualified version.

10828         * print-tree.c (print_node): Display canonical type information
10829         for each type.

10831         alignment of a type for which we're building an array, we end up
10832         guessing wrong, so make the type require structural equality.
10833         * tree.c (make_node_stat): When we build a new type, it is its
10834         own canonical type.
10835         (build_type_attribute_qual_variant): When building an attribute
10836         variant, its canonical type is the non-attribute variant. However,
10837         if the attributes are target-dependent and they differ, we need to
10838         use structural equality checks for this type.
10839         (build_qualified_type): A qualified type is not equivalent to its
10840         unqualified variant; set the canonical type appropriately.
10841         (build_distinct_type_copy): When building a distinct type from
10842         another type, the new type is its own canonical type.

10844         assume that it is equivalent to the original type.

10848         also build a canonical type reference.
10849         (build_index_type): When we can't hash an index type (e.g.,
10850         because its maximum value is negative), the index type requires
10851         structural equality tests.
10852         (build_array_type): Build the canonical form of an array type.
10853         (build_function_type): Function types require structural equality,
10854         because they contain default arguments, attributes, etc.
10855         (build_method_type_directly): Ditto for method types.
10856         (build_offset_type): Build the canonical offset type.

10868         parameter for verifying canonical types.
