6169 2007-01-02 Douglas Gregor <doug.gregor@gmail.com>
6171 * c-common.c (c_common_nodes_and_builtins): Since variants of
6172 void_type_node get built before it is given a name, we need to
6173 give those variants the name, too.
6174 (complete_array_type): We need to work with the canonical main
6175 type of the array, from which we will build the qualified version.
6176 * params.def (PARAM_VERIFY_CANONICAL_TYPES): New.
6177 * print-tree.c (print_node): Display canonical type information
6179 * stor-layout.c (layout_type): When we don't know the
6180 alignment of a type for which we're building an array, we end up
6181 guessing wrong, so make the type require structural equality.
6182 * tree.c (make_node_stat): When we build a new type, it is its
6184 (build_type_attribute_qual_variant): When building an attribute
6185 variant, its canonical type is the non-attribute variant. However,
6186 if the attributes are target-dependent and they differ, we need to
6187 use structural equality checks for this type.
6188 (build_qualified_type): A qualified type is not equivalent to its
6189 unqualified variant; set the canonical type appropriately.
6190 (build_distinct_type_copy): When building a distinct type from
6191 another type, the new type is its own canonical type.
6192 (build_variant_type_copy): When building a new type variant, we
6193 assume that it is equivalent to the original type.
6194 (build_pointer_type_for_mode): When building a pointer type, also
6195 build a canonical type pointer.
6196 (build_reference_type_for_mode): When building a reference type,
6197 also build a canonical type reference.
6198 (build_index_type): When we can't hash an index type (e.g.,
6199 because its maximum value is negative), the index type requires
6200 structural equality tests.
6201 (build_array_type): Build the canonical form of an array type.
6202 (build_function_type): Function types require structural equality,
6203 because they contain default arguments, attributes, etc.
6204 (build_method_type_directly): Ditto for method types.
6205 (build_offset_type): Build the canonical offset type.
6206 (build_complex_type): Build the canonical vector type.
6207 (make_vector_type): Build the canonical vector type.

6217 parameter for verifying canonical types.
