18665 * c-common.c (c_common_nodes_and_builtins): Since variants of
18666 void_type_node get built before it is given a name, we need to
18667 give those variants the name, too.
18668 (complete_array_type): We need to work with the canonical main
18669 type of the array, from which we will build the qualified version.
18670 * params.def (PARAM_VERIFY_CANONICAL_TYPES): New.
18671 * print-tree.c (print_node): Display canonical type information
18673 * stor-layout.c (layout_type): When we don't know the
18674 alignment of a type for which we're building an array, we end up
18675 guessing wrong, so make the type require structural equality.
18676 * tree.c (make_node_stat): When we build a new type, it is its
18677 own canonical type.
18678 (build_type_attribute_qual_variant): When building an attribute
18679 variant, its canonical type is the non-attribute variant. However,
18680 if the attributes are target-dependent and they differ, we need to
18681 use structural equality checks for this type.
18682 (build_qualified_type): A qualified type is not equivalent to its
18683 unqualified variant; set the canonical type appropriately.
18684 (build_distinct_type_copy): When building a distinct type from
18685 another type, the new type is its own canonical type.
18686 (build_variant_type_copy): When building a new type variant, we
18687 assume that it is equivalent to the original type.
18688 (build_pointer_type_for_mode): When building a pointer type, also
18689 build a canonical type pointer.
18690 (build_reference_type_for_mode): When building a reference type,
18691 also build a canonical type reference.
18692 (build_index_type): When we can't hash an index type (e.g.,
18693 because its maximum value is negative), the index type requires
18694 structural equality tests.
18695 (build_array_type): Build the canonical form of an array type.
18696 (build_function_type): Function types require structural equality,
18697 because they contain default arguments, attributes, etc.
18698 (build_method_type_directly): Ditto for method types.
18699 (build_offset_type): Build the canonical offset type.
