34032         * stor-layout.c (layout_type): When we don't know the
34033         alignment of a type for which we're building an array, we end up
34034         guessing wrong, so make the type require structural equality.
34035         * tree.c (make_node_stat): When we build a new type, it is its
34036         own canonical type.
34037         (build_type_attribute_qual_variant): When building an attribute
34038         variant, its canonical type is the non-attribute variant. However,
34039         if the attributes are target-dependent and they differ, we need to
34040         use structural equality checks for this type.
34041         (build_qualified_type): A qualified type is not equivalent to its
34042         unqualified variant; set the canonical type appropriately.
34043         (build_distinct_type_copy): When building a distinct type from
34044         another type, the new type is its own canonical type.

34046         assume that it is equivalent to the original type.

34048         build a canonical type pointer.
34049         (build_reference_type_for_mode): When building a reference type,
34050         also build a canonical type reference.
34051         (build_index_type): When we can't hash an index type (e.g.,
34052         because its maximum value is negative), the index type requires
34053         structural equality tests.
34054         (build_array_type): Build the canonical form of an array type.
34055         (build_function_type): Function types require structural equality,
34056         because they contain default arguments, attributes, etc.
34057         (build_method_type_directly): Ditto for method types.
34058         (build_offset_type): Build the canonical offset type.

34069         * doc/invoke.texi (verify-canonical-types): Document --param
34070         parameter for verifying canonical types.
