1618
1619         * c-common.c(c_common_nodes_and_builtins): Since variants of
1620         void_type_node get built before it is given a name, we need to
1621         give those variants the name, too.
1622         (complete_array_type): We need to work with the canonical main
1623         type of the array, from which we will build the qualified version.

1628         alignment of a type for which we're building an array, we end up

1630         * tree.c (make_node_stat): When we build a new type, it is its
1631         own canonical type.
1632         (build_type_attribute_qual_variant): When building an attribute
1633         variant, its canonical type is the non-attribute variant. However,

1635         use structural equality checks for this type.
1636         (build_qualified_type): A qualified type is not equivalent to its
1637         unqualified variant; set the canonical type appropriately.

1639         another type, the new type is its own canonical type.

1645         also build a canonical type reference.
1646         (build_index_type): When we can't hash an index type (e.g.,
1647         because its maximum value is negative), the index type requires
1648         structural equality tests.
1649         (build_array_type): Build the canonical form of an array type.
1650         (build_function_type): Function types require structural equality,

1653         (build_offset_type): Build the canonical offset type.
