1030
1031         * c-common.c(c_common_nodes_and_builtins): Since variants of
1032         void_type_node get built before it is given a name, we need to
1033         give those variants the name, too.
1034         (complete_array_type): We need to work with the canonical main
1035         type of the array, from which we will build the qualified version.

1040         alignment of a type for which we're building an array, we end up

1042         * tree.c (make_node_stat): When we build a new type, it is its
1043         own canonical type.
1044         (build_type_attribute_qual_variant): When building an attribute
1045         variant, its canonical type is the non-attribute variant. However,

1047         use structural equality checks for this type.
1048         (build_qualified_type): A qualified type is not equivalent to its
1049         unqualified variant; set the canonical type appropriately.

1051         another type, the new type is its own canonical type.

1057         also build a canonical type reference.
1058         (build_index_type): When we can't hash an index type (e.g.,
1059         because its maximum value is negative), the index type requires
1060         structural equality tests.
1061         (build_array_type): Build the canonical form of an array type.
1062         (build_function_type): Function types require structural equality,
1063         because they contain default arguments, attributes, etc.
1064         (build_method_type_directly): Ditto for method types.
1065         (build_offset_type): Build the canonical offset type.
