10814         alignment of a type for which we're building an array, we end up
10815         guessing wrong, so make the type require structural equality.
10816         * tree.c (make_node_stat): When we build a new type, it is its
10817         own canonical type.
10818         (build_type_attribute_qual_variant): When building an attribute
10819         variant, its canonical type is the non-attribute variant. However,
10820         if the attributes are target-dependent and they differ, we need to
10821         use structural equality checks for this type.
10822         (build_qualified_type): A qualified type is not equivalent to its
10823         unqualified variant; set the canonical type appropriately.
10824         (build_distinct_type_copy): When building a distinct type from
10825         another type, the new type is its own canonical type.
10826         (build_variant_type_copy): When building a new type variant, we
10827         assume that it is equivalent to the original type.
10828         (build_pointer_type_for_mode): When building a pointer type, also
10829         build a canonical type pointer.
10830         (build_reference_type_for_mode): When building a reference type,
10831         also build a canonical type reference.
10832         (build_index_type): When we can't hash an index type (e.g.,
10833         because its maximum value is negative), the index type requires
10834         structural equality tests.
10835         (build_array_type): Build the canonical form of an array type.
10836         (build_function_type): Function types require structural equality,
10837         because they contain default arguments, attributes, etc.
10838         (build_method_type_directly): Ditto for method types.
10839         (build_offset_type): Build the canonical offset type.
10840         (build_complex_type): Build the canonical vector type.
10841         (make_vector_type): Build the canonical vector type.

10850         * doc/invoke.texi (verify-canonical-types): Document --param
10851         parameter for verifying canonical types.
