+// For CF functions with 'Get' semantics, the compiler currently assumes that
+// the result is autoreleased and must be retained. It does so on all platforms
+// by emitting a call to objc_retainAutoreleasedReturnValue. On Darwin, this is
+// implemented by the ObjC runtime. On Linux, there is no runtime, and therefore
+// we have to stub it out here ourselves. The compiler will eventually call
+// swift_release to balance the retain below. This is a workaround until the
+// compiler no longer emits this callout on Linux.
