6052         for each type.
6053         * stor-layout.c (layout_type): When we don't know the
6054         alignment of a type for which we're building an array, we end up
6055         guessing wrong, so make the type require structural equality.
6056         * tree.c (make_node_stat): When we build a new type, it is its
6057         own canonical type.
6058         (build_type_attribute_qual_variant): When building an attribute
6059         variant, its canonical type is the non-attribute variant. However,
6060         if the attributes are target-dependent and they differ, we need to
6061         use structural equality checks for this type.
6062         (build_qualified_type): A qualified type is not equivalent to its
6063         unqualified variant; set the canonical type appropriately.

6065         another type, the new type is its own canonical type.

6067         assume that it is equivalent to the original type.

6069         build a canonical type pointer.

6071         also build a canonical type reference.
6072         (build_index_type): When we can't hash an index type (e.g.,
6073         because its maximum value is negative), the index type requires
6074         structural equality tests.
6075         (build_array_type): Build the canonical form of an array type.
6076         (build_function_type): Function types require structural equality,
6077         because they contain default arguments, attributes, etc.
6078         (build_method_type_directly): Ditto for method types.
6079         (build_offset_type): Build the canonical offset type.

6090         * doc/invoke.texi (verify-canonical-types): Document --param
6091         parameter for verifying canonical types.
