3130
3131         * c-common.c(c_common_nodes_and_builtins): Since variants of
3132         void_type_node get built before it is given a name, we need to
3133         give those variants the name, too.
3134         (complete_array_type): We need to work with the canonical main
3135         type of the array, from which we will build the qualified version.
3136         * params.def (PARAM_VERIFY_CANONICAL_TYPES): New.
3137         * print-tree.c (print_node): Display canonical type information
3138         for each type.
3139         * stor-layout.c (layout_type): When we don't know the
3140         alignment of a type for which we're building an array, we end up
3141         guessing wrong, so make the type require structural equality.
3142         * tree.c (make_node_stat): When we build a new type, it is its
3143         own canonical type.
3144         (build_type_attribute_qual_variant): When building an attribute
3145         variant, its canonical type is the non-attribute variant. However,
3146         if the attributes are target-dependent and they differ, we need to
3147         use structural equality checks for this type.
3148         (build_qualified_type): A qualified type is not equivalent to its
3149         unqualified variant; set the canonical type appropriately.
3150         (build_distinct_type_copy): When building a distinct type from
3151         another type, the new type is its own canonical type.
3152         (build_variant_type_copy): When building a new type variant, we
3153         assume that it is equivalent to the original type.

3155         build a canonical type pointer.
3156         (build_reference_type_for_mode): When building a reference type,
3157         also build a canonical type reference.
3158         (build_index_type): When we can't hash an index type (e.g.,
3159         because its maximum value is negative), the index type requires
3160         structural equality tests.
3161         (build_array_type): Build the canonical form of an array type.
3162         (build_function_type): Function types require structural equality,
3163         because they contain default arguments, attributes, etc.
3164         (build_method_type_directly): Ditto for method types.
3165         (build_offset_type): Build the canonical offset type.

3177         parameter for verifying canonical types.
