6061
6062         * c-common.c (c_common_nodes_and_builtins): Since variants of
6063         void_type_node get built before it is given a name, we need to
6064         give those variants the name, too.
6065         (complete_array_type): We need to work with the canonical main
6066         type of the array, from which we will build the qualified version.

6071         alignment of a type for which we're building an array, we end up

6073         * tree.c (make_node_stat): When we build a new type, it is its
6074         own canonical type.
6075         (build_type_attribute_qual_variant): When building an attribute
6076         variant, its canonical type is the non-attribute variant. However,

6078         use structural equality checks for this type.
6079         (build_qualified_type): A qualified type is not equivalent to its
6080         unqualified variant; set the canonical type appropriately.
6081         (build_distinct_type_copy): When building a distinct type from
6082         another type, the new type is its own canonical type.

6088         also build a canonical type reference.
6089         (build_index_type): When we can't hash an index type (e.g.,
6090         because its maximum value is negative), the index type requires
6091         structural equality tests.
6092         (build_array_type): Build the canonical form of an array type.
6093         (build_function_type): Function types require structural equality,
6094         because they contain default arguments, attributes, etc.
6095         (build_method_type_directly): Ditto for method types.
6096         (build_offset_type): Build the canonical offset type.
