9314 * c-common.c (c_common_nodes_and_builtins): Since variants of
9315 void_type_node get built before it is given a name, we need to

9322 * stor-layout.c (layout_type): When we don't know the

9327 (build_type_attribute_qual_variant): When building an attribute
9328 variant, its canonical type is the non-attribute variant. However,
9329 if the attributes are target-dependent and they differ, we need to
9330 use structural equality checks for this type.
9331 (build_qualified_type): A qualified type is not equivalent to its
9332 unqualified variant; set the canonical type appropriately.
9333 (build_distinct_type_copy): When building a distinct type from
9334 another type, the new type is its own canonical type.
9335 (build_variant_type_copy): When building a new type variant, we
9336 assume that it is equivalent to the original type.
9337 (build_pointer_type_for_mode): When building a pointer type, also
9338 build a canonical type pointer.
9339 (build_reference_type_for_mode): When building a reference type,
9340 also build a canonical type reference.
9341 (build_index_type): When we can't hash an index type (e.g.,
9342 because its maximum value is negative), the index type requires
9343 structural equality tests.
9344 (build_array_type): Build the canonical form of an array type.
9345 (build_function_type): Function types require structural equality,
9346 because they contain default arguments, attributes, etc.
9347 (build_method_type_directly): Ditto for method types.
9348 (build_offset_type): Build the canonical offset type.
9349 (build_complex_type): Build the canonical vector type.
