// On Arm v4t there is no blx instruction so all interworking must go via
// a thunk. At present we don't support v4t so we give a warning for unsupported
// features.
// CHECK: warning: lld uses blx instruction, no object with architecture supporting feature detected.
// CHECK-NEXT: warning: lld uses extended branch encoding, no object with architecture supporting feature detected.
// CHECK-NEXT: warning: lld may use movt/movw, no object with architecture supporting feature detected.
