6735 2007-01-02  Douglas Gregor  <doug.gregor@gmail.com>
6737         * c-common.c (c_common_nodes_and_builtins): Since variants of
6738         void_type_node get built before it is given a name, we need to
6739         give those variants the name, too.
6740         (complete_array_type): We need to work with the canonical main
6741         type of the array, from which we will build the qualified version.
6742         * params.def (PARAM_VERIFY_CANONICAL_TYPES): New.
6743         * print-tree.c (print_node): Display canonical type information
6744         for each type.
6745         * stor-layout.c (layout_type): When we don't know the
6746         alignment of a type for which we're building an array, we end up
6747         guessing wrong, so make the type require structural equality.
6748         * tree.c (make_node_stat): When we build a new type, it is its
6749         own canonical type.
6750         (build_type_attribute_qual_variant): When building an attribute
6751         variant, its canonical type is the non-attribute variant. However,
6752         if the attributes are target-dependent and they differ, we need to
6753         use structural equality checks for this type.
6754         (build_qualified_type): A qualified type is not equivalent to its
6755         unqualified variant; set the canonical type appropriately.
6756         (build_distinct_type_copy): When building a distinct type from
6757         another type, the new type is its own canonical type.

6763         also build a canonical type reference.
6764         (build_index_type): When we can't hash an index type (e.g.,
6765         because its maximum value is negative), the index type requires
6766         structural equality tests.
6767         (build_array_type): Build the canonical form of an array type.
6768         (build_function_type): Function types require structural equality,
6769         because they contain default arguments, attributes, etc.
6770         (build_method_type_directly): Ditto for method types.
6771         (build_offset_type): Build the canonical offset type.

6783         parameter for verifying canonical types.
