13383         (complete_array_type): We need to work with the canonical main
13384         type of the array, from which we will build the qualified version.

13389         alignment of a type for which we're building an array, we end up
13390         guessing wrong, so make the type require structural equality.
13391         * tree.c (make_node_stat): When we build a new type, it is its
13392         own canonical type.
13393         (build_type_attribute_qual_variant): When building an attribute
13394         variant, its canonical type is the non-attribute variant. However,
13395         if the attributes are target-dependent and they differ, we need to
13396         use structural equality checks for this type.
13397         (build_qualified_type): A qualified type is not equivalent to its

13399         (build_distinct_type_copy): When building a distinct type from

13404         build a canonical type pointer.
13405         (build_reference_type_for_mode): When building a reference type,
13406         also build a canonical type reference.
13407         (build_index_type): When we can't hash an index type (e.g.,
13408         because its maximum value is negative), the index type requires
13409         structural equality tests.
13410         (build_array_type): Build the canonical form of an array type.
13411         (build_function_type): Function types require structural equality,
13412         because they contain default arguments, attributes, etc.

13414         (build_offset_type): Build the canonical offset type.
