34360 * c-common.c (c_common_nodes_and_builtins): Since variants of
34361 void_type_node get built before it is given a name, we need to
34362 give those variants the name, too.

34368 * stor-layout.c (layout_type): When we don't know the

34372 own canonical type.
34373 (build_type_attribute_qual_variant): When building an attribute
34374 variant, its canonical type is the non-attribute variant. However,
34375 if the attributes are target-dependent and they differ, we need to
34376 use structural equality checks for this type.
34377 (build_qualified_type): A qualified type is not equivalent to its
34378 unqualified variant; set the canonical type appropriately.
34379 (build_distinct_type_copy): When building a distinct type from
34380 another type, the new type is its own canonical type.
34381 (build_variant_type_copy): When building a new type variant, we
34382 assume that it is equivalent to the original type.
34383 (build_pointer_type_for_mode): When building a pointer type, also
34384 build a canonical type pointer.
34385 (build_reference_type_for_mode): When building a reference type,
34386 also build a canonical type reference.
34387 (build_index_type): When we can't hash an index type (e.g.,
34388 because its maximum value is negative), the index type requires
34389 structural equality tests.
34390 (build_array_type): Build the canonical form of an array type.
34391 (build_function_type): Function types require structural equality,
34392 because they contain default arguments, attributes, etc.
34393 (build_method_type_directly): Ditto for method types.
34394 (build_offset_type): Build the canonical offset type.
