// This tls global-dynamic sequence is with respect to a non-preemptible
// symbol in an application so a relaxation to Local Exec would normally be
// possible. This would result in an assertion failure on ARM as the
// relaxation functions can't be implemented on ARM. Check that the sequence
// is handled as global dynamic
