--- Comment #10 from Andreas Schwab <schwab@linux-m68k.org> ---
This issue does not occur when pthread_rwlock_clockwrlock is compiled with gcc
8. With gcc 8, atomic_fetch_add_relaxed in pthread_rwlock_clockwrlock
(pthread_rwlock_common.c:636) uses ldaxr, whereas gcc 9 uses ldxr. Simarily,
the expansion of atomic_compare_exchange_weak_acquire
(pthread_rwlock_common.c:747) has stlxr vs stxr.
