28598         alignment of a type for which we're building an array, we end up
28599         guessing wrong, so make the type require structural equality.
28600         * tree.c (make_node_stat): When we build a new type, it is its
28601         own canonical type.
28602         (build_type_attribute_qual_variant): When building an attribute
28603         variant, its canonical type is the non-attribute variant. However,
28604         if the attributes are target-dependent and they differ, we need to
28605         use structural equality checks for this type.
28606         (build_qualified_type): A qualified type is not equivalent to its
28607         unqualified variant; set the canonical type appropriately.
28608         (build_distinct_type_copy): When building a distinct type from
28609         another type, the new type is its own canonical type.
28610         (build_variant_type_copy): When building a new type variant, we
28611         assume that it is equivalent to the original type.
28612         (build_pointer_type_for_mode): When building a pointer type, also
28613         build a canonical type pointer.
28614         (build_reference_type_for_mode): When building a reference type,
28615         also build a canonical type reference.
28616         (build_index_type): When we can't hash an index type (e.g.,
28617         because its maximum value is negative), the index type requires
28618         structural equality tests.
28619         (build_array_type): Build the canonical form of an array type.
28620         (build_function_type): Function types require structural equality,
28621         because they contain default arguments, attributes, etc.
28622         (build_method_type_directly): Ditto for method types.
28623         (build_offset_type): Build the canonical offset type.
28624         (build_complex_type): Build the canonical vector type.
28625         (make_vector_type): Build the canonical vector type.

28634         * doc/invoke.texi (verify-canonical-types): Document --param
28635         parameter for verifying canonical types.
