24809 * c-common.c (c_common_nodes_and_builtins): Since variants of
24810 void_type_node get built before it is given a name, we need to
24811 give those variants the name, too.
24812 (complete_array_type): We need to work with the canonical main
24813 type of the array, from which we will build the qualified version.

24817 * stor-layout.c (layout_type): When we don't know the
24818 alignment of a type for which we're building an array, we end up
24819 guessing wrong, so make the type require structural equality.
24820 * tree.c (make_node_stat): When we build a new type, it is its
24821 own canonical type.
24822 (build_type_attribute_qual_variant): When building an attribute
24823 variant, its canonical type is the non-attribute variant. However,
24824 if the attributes are target-dependent and they differ, we need to
24825 use structural equality checks for this type.
24826 (build_qualified_type): A qualified type is not equivalent to its
24827 unqualified variant; set the canonical type appropriately.
24828 (build_distinct_type_copy): When building a distinct type from
24829 another type, the new type is its own canonical type.
24830 (build_variant_type_copy): When building a new type variant, we
24831 assume that it is equivalent to the original type.
24832 (build_pointer_type_for_mode): When building a pointer type, also
24833 build a canonical type pointer.
24834 (build_reference_type_for_mode): When building a reference type,
24835 also build a canonical type reference.
24836 (build_index_type): When we can't hash an index type (e.g.,
24837 because its maximum value is negative), the index type requires
24838 structural equality tests.
24839 (build_array_type): Build the canonical form of an array type.
24840 (build_function_type): Function types require structural equality,
24841 because they contain default arguments, attributes, etc.
24842 (build_method_type_directly): Ditto for method types.
24843 (build_offset_type): Build the canonical offset type.
