6162 2007-01-02 Douglas Gregor <doug.gregor@gmail.com>
6164 * c-common.c (c_common_nodes_and_builtins): Since variants of
6165 void_type_node get built before it is given a name, we need to
6166 give those variants the name, too.
6167 (complete_array_type): We need to work with the canonical main
6168 type of the array, from which we will build the qualified version.
6169 * params.def (PARAM_VERIFY_CANONICAL_TYPES): New.
6170 * print-tree.c (print_node): Display canonical type information
6172 * stor-layout.c (layout_type): When we don't know the
6173 alignment of a type for which we're building an array, we end up
6174 guessing wrong, so make the type require structural equality.
6175 * tree.c (make_node_stat): When we build a new type, it is its
6177 (build_type_attribute_qual_variant): When building an attribute
6178 variant, its canonical type is the non-attribute variant. However,
6179 if the attributes are target-dependent and they differ, we need to
6180 use structural equality checks for this type.
6181 (build_qualified_type): A qualified type is not equivalent to its
6182 unqualified variant; set the canonical type appropriately.
6183 (build_distinct_type_copy): When building a distinct type from
6184 another type, the new type is its own canonical type.
6185 (build_variant_type_copy): When building a new type variant, we
6186 assume that it is equivalent to the original type.
6187 (build_pointer_type_for_mode): When building a pointer type, also
6188 build a canonical type pointer.
6189 (build_reference_type_for_mode): When building a reference type,
6190 also build a canonical type reference.
6191 (build_index_type): When we can't hash an index type (e.g.,
6192 because its maximum value is negative), the index type requires
6193 structural equality tests.
6194 (build_array_type): Build the canonical form of an array type.
6195 (build_function_type): Function types require structural equality,
6196 because they contain default arguments, attributes, etc.
6197 (build_method_type_directly): Ditto for method types.
6198 (build_offset_type): Build the canonical offset type.
6199 (build_complex_type): Build the canonical vector type.
6200 (make_vector_type): Build the canonical vector type.

6210 parameter for verifying canonical types.
