28589         alignment of a type for which we're building an array, we end up
28590         guessing wrong, so make the type require structural equality.
28591         * tree.c (make_node_stat): When we build a new type, it is its
28592         own canonical type.
28593         (build_type_attribute_qual_variant): When building an attribute
28594         variant, its canonical type is the non-attribute variant. However,
28595         if the attributes are target-dependent and they differ, we need to
28596         use structural equality checks for this type.
28597         (build_qualified_type): A qualified type is not equivalent to its
28598         unqualified variant; set the canonical type appropriately.
28599         (build_distinct_type_copy): When building a distinct type from
28600         another type, the new type is its own canonical type.
28601         (build_variant_type_copy): When building a new type variant, we
28602         assume that it is equivalent to the original type.
28603         (build_pointer_type_for_mode): When building a pointer type, also
28604         build a canonical type pointer.
28605         (build_reference_type_for_mode): When building a reference type,
28606         also build a canonical type reference.
28607         (build_index_type): When we can't hash an index type (e.g.,
28608         because its maximum value is negative), the index type requires
28609         structural equality tests.
28610         (build_array_type): Build the canonical form of an array type.
28611         (build_function_type): Function types require structural equality,
28612         because they contain default arguments, attributes, etc.
28613         (build_method_type_directly): Ditto for method types.
28614         (build_offset_type): Build the canonical offset type.
28615         (build_complex_type): Build the canonical vector type.
28616         (make_vector_type): Build the canonical vector type.

28625         * doc/invoke.texi (verify-canonical-types): Document --param
28626         parameter for verifying canonical types.
