6044         for each type.
6045         * stor-layout.c (layout_type): When we don't know the
6046         alignment of a type for which we're building an array, we end up
6047         guessing wrong, so make the type require structural equality.
6048         * tree.c (make_node_stat): When we build a new type, it is its
6049         own canonical type.
6050         (build_type_attribute_qual_variant): When building an attribute
6051         variant, its canonical type is the non-attribute variant. However,
6052         if the attributes are target-dependent and they differ, we need to
6053         use structural equality checks for this type.
6054         (build_qualified_type): A qualified type is not equivalent to its
6055         unqualified variant; set the canonical type appropriately.
6056         (build_distinct_type_copy): When building a distinct type from
6057         another type, the new type is its own canonical type.

6059         assume that it is equivalent to the original type.
6060         (build_pointer_type_for_mode): When building a pointer type, also
6061         build a canonical type pointer.
6062         (build_reference_type_for_mode): When building a reference type,
6063         also build a canonical type reference.
6064         (build_index_type): When we can't hash an index type (e.g.,
6065         because its maximum value is negative), the index type requires
6066         structural equality tests.
6067         (build_array_type): Build the canonical form of an array type.
6068         (build_function_type): Function types require structural equality,
6069         because they contain default arguments, attributes, etc.
6070         (build_method_type_directly): Ditto for method types.
6071         (build_offset_type): Build the canonical offset type.

6082         * doc/invoke.texi (verify-canonical-types): Document --param
6083         parameter for verifying canonical types.
