22782 * c-common.c (c_common_nodes_and_builtins): Since variants of
22783 void_type_node get built before it is given a name, we need to
22784 give those variants the name, too.
22785 (complete_array_type): We need to work with the canonical main

22790 * stor-layout.c (layout_type): When we don't know the
22791 alignment of a type for which we're building an array, we end up
22792 guessing wrong, so make the type require structural equality.
22793 * tree.c (make_node_stat): When we build a new type, it is its
22794 own canonical type.
22795 (build_type_attribute_qual_variant): When building an attribute
22796 variant, its canonical type is the non-attribute variant. However,
22797 if the attributes are target-dependent and they differ, we need to
22798 use structural equality checks for this type.
22799 (build_qualified_type): A qualified type is not equivalent to its
22800 unqualified variant; set the canonical type appropriately.
22801 (build_distinct_type_copy): When building a distinct type from
22802 another type, the new type is its own canonical type.
22803 (build_variant_type_copy): When building a new type variant, we
22804 assume that it is equivalent to the original type.
22805 (build_pointer_type_for_mode): When building a pointer type, also
22806 build a canonical type pointer.
22807 (build_reference_type_for_mode): When building a reference type,
22808 also build a canonical type reference.
22809 (build_index_type): When we can't hash an index type (e.g.,
22810 because its maximum value is negative), the index type requires
22811 structural equality tests.
22812 (build_array_type): Build the canonical form of an array type.
22813 (build_function_type): Function types require structural equality,
22814 because they contain default arguments, attributes, etc.
22815 (build_method_type_directly): Ditto for method types.
