8966
8967         * c-common.c (c_common_nodes_and_builtins): Since variants of
8968         void_type_node get built before it is given a name, we need to
8969         give those variants the name, too.
8970         (complete_array_type): We need to work with the canonical main

8976         alignment of a type for which we're building an array, we end up

8978         * tree.c (make_node_stat): When we build a new type, it is its
8979         own canonical type.
8980         (build_type_attribute_qual_variant): When building an attribute
8981         variant, its canonical type is the non-attribute variant. However,

8983         use structural equality checks for this type.
8984         (build_qualified_type): A qualified type is not equivalent to its
8985         unqualified variant; set the canonical type appropriately.

8987         another type, the new type is its own canonical type.

8995         because its maximum value is negative), the index type requires
8996         structural equality tests.
8997         (build_array_type): Build the canonical form of an array type.
8998         (build_function_type): Function types require structural equality,

9001         (build_offset_type): Build the canonical offset type.
