6020 2007-01-02  Douglas Gregor  <doug.gregor@gmail.com>
6022         * c-common.c (c_common_nodes_and_builtins): Since variants of
6023         void_type_node get built before it is given a name, we need to
6024         give those variants the name, too.
6025         (complete_array_type): We need to work with the canonical main
6026         type of the array, from which we will build the qualified version.

6028         * print-tree.c (print_node): Display canonical type information
6029         for each type.

6031         alignment of a type for which we're building an array, we end up
6032         guessing wrong, so make the type require structural equality.
6033         * tree.c (make_node_stat): When we build a new type, it is its
6034         own canonical type.
6035         (build_type_attribute_qual_variant): When building an attribute
6036         variant, its canonical type is the non-attribute variant. However,

6038         use structural equality checks for this type.
6039         (build_qualified_type): A qualified type is not equivalent to its
6040         unqualified variant; set the canonical type appropriately.

6042         another type, the new type is its own canonical type.

6044         assume that it is equivalent to the original type.

6048         also build a canonical type reference.
6049         (build_index_type): When we can't hash an index type (e.g.,
6050         because its maximum value is negative), the index type requires
6051         structural equality tests.
6052         (build_array_type): Build the canonical form of an array type.
6053         (build_function_type): Function types require structural equality,
6054         because they contain default arguments, attributes, etc.
6055         (build_method_type_directly): Ditto for method types.
6056         (build_offset_type): Build the canonical offset type.
