6805 * c-common.c (c_common_nodes_and_builtins): Since variants of
6806 void_type_node get built before it is given a name, we need to
6807 give those variants the name, too.
6808 (complete_array_type): We need to work with the canonical main
6809 type of the array, from which we will build the qualified version.
6810 * params.def (PARAM_VERIFY_CANONICAL_TYPES): New.
6811 * print-tree.c (print_node): Display canonical type information
6812 for each type.
6813 * stor-layout.c (layout_type): When we don't know the
6814 alignment of a type for which we're building an array, we end up
6815 guessing wrong, so make the type require structural equality.
6816 * tree.c (make_node_stat): When we build a new type, it is its
6817 own canonical type.
6818 (build_type_attribute_qual_variant): When building an attribute
6819 variant, its canonical type is the non-attribute variant. However,
6820 if the attributes are target-dependent and they differ, we need to
6821 use structural equality checks for this type.
6822 (build_qualified_type): A qualified type is not equivalent to its
6823 unqualified variant; set the canonical type appropriately.
6824 (build_distinct_type_copy): When building a distinct type from
6825 another type, the new type is its own canonical type.
6826 (build_variant_type_copy): When building a new type variant, we
6827 assume that it is equivalent to the original type.
6828 (build_pointer_type_for_mode): When building a pointer type, also
6829 build a canonical type pointer.
6830 (build_reference_type_for_mode): When building a reference type,
6831 also build a canonical type reference.
6832 (build_index_type): When we can't hash an index type (e.g.,
6833 because its maximum value is negative), the index type requires
6834 structural equality tests.
6835 (build_array_type): Build the canonical form of an array type.
6836 (build_function_type): Function types require structural equality,
6837 because they contain default arguments, attributes, etc.
6838 (build_method_type_directly): Ditto for method types.
6839 (build_offset_type): Build the canonical offset type.
6840 (build_complex_type): Build the canonical vector type.
6841 (make_vector_type): Build the canonical vector type.
6842 * tree.h (TYPE_CANONICAL): New.
6843 (TYPE_STRUCTURAL_EQUALITY_P): New.
6844 (SET_TYPE_STRUCTURAL_EQUALITY): New.
6845 (struct tree_type): Added "canonical" field.
6846 * params.h (VERIFY_CANONICAL_TYPES): New.

6848 (TYPE_STRUCTURAL_EQUALITY_P): Document.
6849 (SET_TYPE_STRUCTURAL_EQUALITY): Document.
6850 * doc/invoke.texi (verify-canonical-types): Document --param
6851 parameter for verifying canonical types.
