12802         for each type.
12803         * stor-layout.c (layout_type): When we don't know the
12804         alignment of a type for which we're building an array, we end up
12805         guessing wrong, so make the type require structural equality.
12806         * tree.c (make_node_stat): When we build a new type, it is its
12807         own canonical type.
12808         (build_type_attribute_qual_variant): When building an attribute
12809         variant, its canonical type is the non-attribute variant. However,
12810         if the attributes are target-dependent and they differ, we need to
12811         use structural equality checks for this type.
12812         (build_qualified_type): A qualified type is not equivalent to its
12813         unqualified variant; set the canonical type appropriately.
12814         (build_distinct_type_copy): When building a distinct type from
12815         another type, the new type is its own canonical type.
12816         (build_variant_type_copy): When building a new type variant, we
12817         assume that it is equivalent to the original type.
12818         (build_pointer_type_for_mode): When building a pointer type, also
12819         build a canonical type pointer.
12820         (build_reference_type_for_mode): When building a reference type,
12821         also build a canonical type reference.
12822         (build_index_type): When we can't hash an index type (e.g.,
12823         because its maximum value is negative), the index type requires
12824         structural equality tests.
12825         (build_array_type): Build the canonical form of an array type.
12826         (build_function_type): Function types require structural equality,
12827         because they contain default arguments, attributes, etc.
12828         (build_method_type_directly): Ditto for method types.
12829         (build_offset_type): Build the canonical offset type.
12830         (build_complex_type): Build the canonical vector type.
12831         (make_vector_type): Build the canonical vector type.
12832         * tree.h (TYPE_CANONICAL): New.
