3131         for each type.
3132         * stor-layout.c (layout_type): When we don't know the
3133         alignment of a type for which we're building an array, we end up
3134         guessing wrong, so make the type require structural equality.
3135         * tree.c (make_node_stat): When we build a new type, it is its
3136         own canonical type.
3137         (build_type_attribute_qual_variant): When building an attribute
3138         variant, its canonical type is the non-attribute variant. However,
3139         if the attributes are target-dependent and they differ, we need to
3140         use structural equality checks for this type.
3141         (build_qualified_type): A qualified type is not equivalent to its
3142         unqualified variant; set the canonical type appropriately.

3144         another type, the new type is its own canonical type.

3146         assume that it is equivalent to the original type.

3148         build a canonical type pointer.

3150         also build a canonical type reference.
3151         (build_index_type): When we can't hash an index type (e.g.,
3152         because its maximum value is negative), the index type requires
3153         structural equality tests.
3154         (build_array_type): Build the canonical form of an array type.
3155         (build_function_type): Function types require structural equality,
3156         because they contain default arguments, attributes, etc.
3157         (build_method_type_directly): Ditto for method types.
3158         (build_offset_type): Build the canonical offset type.

3169         * doc/invoke.texi (verify-canonical-types): Document --param
3170         parameter for verifying canonical types.
