5745 * c-common.c (c_common_nodes_and_builtins): Since variants of
5746 void_type_node get built before it is given a name, we need to
5747 give those variants the name, too.
5748 (complete_array_type): We need to work with the canonical main
5749 type of the array, from which we will build the qualified version.

5753 * stor-layout.c (layout_type): When we don't know the
5754 alignment of a type for which we're building an array, we end up
5755 guessing wrong, so make the type require structural equality.

5758 (build_type_attribute_qual_variant): When building an attribute
5759 variant, its canonical type is the non-attribute variant. However,
5760 if the attributes are target-dependent and they differ, we need to
5761 use structural equality checks for this type.
5762 (build_qualified_type): A qualified type is not equivalent to its
5763 unqualified variant; set the canonical type appropriately.
5764 (build_distinct_type_copy): When building a distinct type from
5765 another type, the new type is its own canonical type.
5766 (build_variant_type_copy): When building a new type variant, we
5767 assume that it is equivalent to the original type.
5768 (build_pointer_type_for_mode): When building a pointer type, also
5769 build a canonical type pointer.
5770 (build_reference_type_for_mode): When building a reference type,
5771 also build a canonical type reference.
5772 (build_index_type): When we can't hash an index type (e.g.,
5773 because its maximum value is negative), the index type requires
5774 structural equality tests.
5775 (build_array_type): Build the canonical form of an array type.
5776 (build_function_type): Function types require structural equality,
5777 because they contain default arguments, attributes, etc.
5778 (build_method_type_directly): Ditto for method types.
5779 (build_offset_type): Build the canonical offset type.
5780 (build_complex_type): Build the canonical vector type.

5791 parameter for verifying canonical types.
