Description

CodegenAnyVal::Compare() generates code which calls the cross
compiled version of RawValue::Compare() without propagating
the type information into RawValue::Compare(). As a result,
the generated code of RawValue::Compare() is not any more
efficient than the interpreted version as we still have
the big switch statement in it.
