@Retention(value=CLASS) @Target(value=METHOD) public static @interface ReportPolymorphism.Megamorphic
report a polymorphic specialization. This annotation can be used independently of
ReportPolymorphism. This means that a node need not report every polymorphic specialization as with
ReportPolymorphismbut only ones that produce generic and expensive cases. For example, if a node has several fast specializations and a very slow generic specialization it does not make sense to report activations of these fast specializations as polymorphic specializations as they perform well even without runtime intervention (e.g. Splitting). On the other hand, the activation of the generic case is slow and something that the runtime might be able to remove.
