// This test requires a target of OS X 10.51 or later to test deprecation
// diagnostics because (1) we only emit deprecation warnings if a symbol is
// deprecated on all deployment targets and (2) symbols deprecated on 10.9 and
// earlier are imported as unavailable.
//
// We run this test with FileCheck, as well, because the DiagnosticVerifier
// swallows diagnostics from buffers with unknown filenames, which is
// how diagnostics with invalid source locations appear. The
// --implicit-check-not checks to make sure we do not emit any such
// diagnostics with invalid source locations.

// REQUIRES: OS=macosx
