6417 2007-01-02  Douglas Gregor  <doug.gregor@gmail.com>
6419         * c-common.c (c_common_nodes_and_builtins): Since variants of
6420         void_type_node get built before it is given a name, we need to
6421         give those variants the name, too.
6422         (complete_array_type): We need to work with the canonical main
6423         type of the array, from which we will build the qualified version.

6425         * print-tree.c (print_node): Display canonical type information
6426         for each type.

6428         alignment of a type for which we're building an array, we end up
6429         guessing wrong, so make the type require structural equality.
6430         * tree.c (make_node_stat): When we build a new type, it is its
6431         own canonical type.
6432         (build_type_attribute_qual_variant): When building an attribute
6433         variant, its canonical type is the non-attribute variant. However,
6434         if the attributes are target-dependent and they differ, we need to
6435         use structural equality checks for this type.
6436         (build_qualified_type): A qualified type is not equivalent to its
6437         unqualified variant; set the canonical type appropriately.
6438         (build_distinct_type_copy): When building a distinct type from
6439         another type, the new type is its own canonical type.
6440         (build_variant_type_copy): When building a new type variant, we
6441         assume that it is equivalent to the original type.

6443         build a canonical type pointer.

6445         also build a canonical type reference.
6446         (build_index_type): When we can't hash an index type (e.g.,
6447         because its maximum value is negative), the index type requires
6448         structural equality tests.
6449         (build_array_type): Build the canonical form of an array type.
6450         (build_function_type): Function types require structural equality,
6451         because they contain default arguments, attributes, etc.
6452         (build_method_type_directly): Ditto for method types.
6453         (build_offset_type): Build the canonical offset type.

6465         parameter for verifying canonical types.
