6676 * c-common.c (c_common_nodes_and_builtins): Since variants of
6677 void_type_node get built before it is given a name, we need to
6678 give those variants the name, too.
6679 (complete_array_type): We need to work with the canonical main
6680 type of the array, from which we will build the qualified version.

6684 * stor-layout.c (layout_type): When we don't know the
6685 alignment of a type for which we're building an array, we end up
6686 guessing wrong, so make the type require structural equality.

6689 (build_type_attribute_qual_variant): When building an attribute
6690 variant, its canonical type is the non-attribute variant. However,
6691 if the attributes are target-dependent and they differ, we need to
6692 use structural equality checks for this type.
6693 (build_qualified_type): A qualified type is not equivalent to its
6694 unqualified variant; set the canonical type appropriately.
6695 (build_distinct_type_copy): When building a distinct type from
6696 another type, the new type is its own canonical type.
6697 (build_variant_type_copy): When building a new type variant, we
6698 assume that it is equivalent to the original type.
6699 (build_pointer_type_for_mode): When building a pointer type, also
6700 build a canonical type pointer.
6701 (build_reference_type_for_mode): When building a reference type,
6702 also build a canonical type reference.
6703 (build_index_type): When we can't hash an index type (e.g.,
6704 because its maximum value is negative), the index type requires
6705 structural equality tests.
6706 (build_array_type): Build the canonical form of an array type.
6707 (build_function_type): Function types require structural equality,
6708 because they contain default arguments, attributes, etc.
6709 (build_method_type_directly): Ditto for method types.
6710 (build_offset_type): Build the canonical offset type.
6711 (build_complex_type): Build the canonical vector type.
