2149 2007-01-02 Douglas Gregor <doug.gregor@gmail.com>
2151 * c-common.c(c_common_nodes_and_builtins): Since variants of
2152 void_type_node get built before it is given a name, we need to
2153 give those variants the name, too.
2154 (complete_array_type): We need to work with the canonical main
2155 type of the array, from which we will build the qualified version.
2156 * params.def (PARAM_VERIFY_CANONICAL_TYPES): New.
2157 * print-tree.c (print_node): Display canonical type information
2159 * stor-layout.c (layout_type): When we don't know the
2160 alignment of a type for which we're building an array, we end up
2161 guessing wrong, so make the type require structural equality.
2162 * tree.c (make_node_stat): When we build a new type, it is its
2164 (build_type_attribute_qual_variant): When building an attribute
2165 variant, its canonical type is the non-attribute variant. However,
2166 if the attributes are target-dependent and they differ, we need to
2167 use structural equality checks for this type.
2168 (build_qualified_type): A qualified type is not equivalent to its
2169 unqualified variant; set the canonical type appropriately.
2170 (build_distinct_type_copy): When building a distinct type from
2171 another type, the new type is its own canonical type.
2172 (build_variant_type_copy): When building a new type variant, we
2173 assume that it is equivalent to the original type.
2174 (build_pointer_type_for_mode): When building a pointer type, also
2175 build a canonical type pointer.
2176 (build_reference_type_for_mode): When building a reference type,
2177 also build a canonical type reference.
2178 (build_index_type): When we can't hash an index type (e.g.,
2179 because its maximum value is negative), the index type requires
2180 structural equality tests.
2181 (build_array_type): Build the canonical form of an array type.
2182 (build_function_type): Function types require structural equality,
2183 because they contain default arguments, attributes, etc.
2184 (build_method_type_directly): Ditto for method types.
2185 (build_offset_type): Build the canonical offset type.
2186 (build_complex_type): Build the canonical vector type.
2187 (make_vector_type): Build the canonical vector type.

2197 parameter for verifying canonical types.
