// This test checks for correct serialization & deserialization of
// @actorIndependent and @actorIndependent(unsafe)

// look for correct annotation after first deserialization's module print:

// MODULE-CHECK:      actor class UnsafeCounter {
// MODULE-CHECK-NEXT:   @actorIndependent(unsafe) var storage: Int
// MODULE-CHECK-NEXT:   @actorIndependent var count: Int
// MODULE-CHECK-NEXT:   var actorCount: Int
// MODULE-CHECK-NEXT:   @actorIndependent(unsafe) func enqueue(partialTask: PartialAsyncTask)
// MODULE-CHECK-NEXT:   init()
// MODULE-CHECK-NEXT: }

// and look for unsafe and safe versions of decl in BC dump:

// BC-CHECK-NOT: UnknownCode
// BC-CHECK: <ActorIndependent_DECL_ATTR abbrevid={{[0-9]+}} op0=1/>
// BC-CHECK: <ActorIndependent_DECL_ATTR abbrevid={{[0-9]+}} op0=0/>
