25239 * c-common.c (c_common_nodes_and_builtins): Since variants of
25240 void_type_node get built before it is given a name, we need to
25241 give those variants the name, too.
25242 (complete_array_type): We need to work with the canonical main

25247 * stor-layout.c (layout_type): When we don't know the
25248 alignment of a type for which we're building an array, we end up
25249 guessing wrong, so make the type require structural equality.
25250 * tree.c (make_node_stat): When we build a new type, it is its
25251 own canonical type.
25252 (build_type_attribute_qual_variant): When building an attribute
25253 variant, its canonical type is the non-attribute variant. However,
25254 if the attributes are target-dependent and they differ, we need to
25255 use structural equality checks for this type.
25256 (build_qualified_type): A qualified type is not equivalent to its
25257 unqualified variant; set the canonical type appropriately.
25258 (build_distinct_type_copy): When building a distinct type from
25259 another type, the new type is its own canonical type.
25260 (build_variant_type_copy): When building a new type variant, we
25261 assume that it is equivalent to the original type.
25262 (build_pointer_type_for_mode): When building a pointer type, also
25263 build a canonical type pointer.
25264 (build_reference_type_for_mode): When building a reference type,
25265 also build a canonical type reference.
25266 (build_index_type): When we can't hash an index type (e.g.,
25267 because its maximum value is negative), the index type requires
25268 structural equality tests.
25269 (build_array_type): Build the canonical form of an array type.
25270 (build_function_type): Function types require structural equality,
25271 because they contain default arguments, attributes, etc.
25272 (build_method_type_directly): Ditto for method types.
