9751 * c-common.c (c_common_nodes_and_builtins): Since variants of
9752 void_type_node get built before it is given a name, we need to
9753 give those variants the name, too.
9754 (complete_array_type): We need to work with the canonical main
9755 type of the array, from which we will build the qualified version.

9759 * stor-layout.c (layout_type): When we don't know the
9760 alignment of a type for which we're building an array, we end up
9761 guessing wrong, so make the type require structural equality.

9764 (build_type_attribute_qual_variant): When building an attribute
9765 variant, its canonical type is the non-attribute variant. However,
9766 if the attributes are target-dependent and they differ, we need to
9767 use structural equality checks for this type.
9768 (build_qualified_type): A qualified type is not equivalent to its
9769 unqualified variant; set the canonical type appropriately.
9770 (build_distinct_type_copy): When building a distinct type from
9771 another type, the new type is its own canonical type.
9772 (build_variant_type_copy): When building a new type variant, we
9773 assume that it is equivalent to the original type.
9774 (build_pointer_type_for_mode): When building a pointer type, also
9775 build a canonical type pointer.
9776 (build_reference_type_for_mode): When building a reference type,
9777 also build a canonical type reference.
9778 (build_index_type): When we can't hash an index type (e.g.,
9779 because its maximum value is negative), the index type requires
9780 structural equality tests.
9781 (build_array_type): Build the canonical form of an array type.
9782 (build_function_type): Function types require structural equality,
9783 because they contain default arguments, attributes, etc.
9784 (build_method_type_directly): Ditto for method types.
9785 (build_offset_type): Build the canonical offset type.
9786 (build_complex_type): Build the canonical vector type.
