 129         (complete_array_type): We need to work with the canonical main

 138         own canonical type.

 140         variant, its canonical type is the non-attribute variant. However,

 144         unqualified variant; set the canonical type appropriately.

 146         another type, the new type is its own canonical type.

 152         also build a canonical type reference.
 153         (build_index_type): When we can't hash an index type (e.g.,
 154         because its maximum value is negative), the index type requires
 155         structural equality tests.
 156         (build_array_type): Build the canonical form of an array type.
 157         (build_function_type): Function types require structural equality,
 158         because they contain default arguments, attributes, etc.
 159         (build_method_type_directly): Ditto for method types.
 160         (build_offset_type): Build the canonical offset type.
