  14. class SpecializationDuplicator extends Duplicator

    Introduced to fix scala/bug#7343: Phase ordering problem between Duplicators and Specialization.

    Introduced to fix scala/bug#7343: Phase ordering problem between Duplicators and Specialization. brief explanation: specialization rewires class parents during info transformation, and the new info then guides the tree changes. But if a symbol is created during duplication, which runs after specialization, its info is not visited and thus the corresponding tree is not specialized. One manifestation is the following: object Test { class Parent[@specialized(Int) T]

    def spec_method[@specialized(Int) T](t: T, expectedXSuper: String) = { class X extends Parent[T]() // even in the specialized variant, the local X class // doesn't extend Parent$mcI$sp, since its symbol has // been created after specialization and was not seen // by specialization's info transformer. ... } } We fix this by forcing duplication to take place before specialization.

    Note: The constructors phase (which also uses duplication) comes after erasure and uses the post-erasure typer => we must protect it from the beforeSpecialization phase shifting.
