nptl: Add POSIX-proposed pthread_rwlock_clockrdlock & pthread_rwlock_clockwrlock
Add:
int pthread_rwlock_clockrdlock (pthread_rwlock_t *rwlock,
clockid_t clockid,
const struct timespec *abstime)
and:
int pthread_rwlock_clockwrlock (pthread_rwlock_t *rwlock,
clockid_t clockid,
const struct timespec *abstime)
which behave like pthread_rwlock_timedrdlock and
pthread_rwlock_timedwrlock respectively, except they always measure
abstime against the supplied clockid. The functions currently support
CLOCK_REALTIME and CLOCK_MONOTONIC and return EINVAL if any other
clock is specified.
* sysdeps/nptl/pthread.h: Add pthread_rwlock_clockrdlock and
pthread_wrlock_clockwrlock.
* nptl/Makefile: Build pthread_rwlock_clockrdlock.c and
pthread_rwlock_clockwrlock.c.
* nptl/pthread_rwlock_clockrdlock.c: Implement
pthread_rwlock_clockrdlock.
* nptl/pthread_rwlock_clockwrlock.c: Implement
pthread_rwlock_clockwrlock.
* nptl/pthread_rwlock_common.c (__pthread_rwlock_rdlock_full): Add
clockid parameter and verify that it indicates a supported clock on
entry so that we fail even if it doesn't end up being used. Pass
that clock on to futex_abstimed_wait when necessary.
(__pthread_rwlock_wrlock_full): Likewise.
* nptl/pthread_rwlock_rdlock.c: (__pthread_rwlock_rdlock): Pass
CLOCK_REALTIME to __pthread_rwlock_rdlock_full even though it won't
be used because there's no timeout.
* nptl/pthread_rwlock_wrlock.c (__pthread_rwlock_wrlock): Pass
CLOCK_REALTIME to __pthread_rwlock_wrlock_full even though it won't
be used because there is no timeout.
* nptl/pthread_rwlock_timedrdlock.c (pthread_rwlock_timedrdlock):
Pass CLOCK_REALTIME to __pthread_rwlock_rdlock_full since abstime
uses that clock.
* nptl/pthread_rwlock_timedwrlock.c (pthread_rwlock_timedwrlock):
Pass CLOCK_REALTIME to __pthread_rwlock_wrlock_full since abstime
uses that clock.

pthread_rwlock_clockwrlock timeout tests to match the existing
pthread_rwlock_timedrdloock and pthread_rwlock_timedwrlock tests.
* nptl/tst-rwlock14.c (do_test): Likewise.
* nptl/tst-rwlock6.c Invent verbose_printf macro, and use for
ancillary output throughout. (tf): Accept thread_args structure so
that rwlock, a clockid and function name can be passed to the
thread. (do_test_clock): Rename from do_test. Accept clockid
parameter to specify test clock. Use the magic clockid value of
CLOCK_USE_TIMEDLOCK to indicate that pthread_rwlock_timedrdlock and
pthread_rwlock_timedwrlock should be tested, otherwise pass the
specified clockid to pthread_rwlock_clockrdlock and
pthread_rwlock_clockwrlock. Use xpthread_create and xpthread_join.
(do_test): Call do_test_clock to test each clockid in turn.
* nptl/tst-rwlock7.c: Likewise.
* nptl/tst-rwlock9.c (writer_thread, reader_thread): Accept
thread_args structure so that the (now int) thread number, the
clockid and the function name can be passed to the thread.
(do_test_clock): Renamed from do_test. Pass the necessary
thread_args when creating the reader and writer threads. Use
xpthread_create and xpthread_join.
(do_test): Call do_test_clock to test each clockid in turn.
* manual/threads.texi: Add documentation for
pthread_rwlock_clockrdlock and pthread_rwlock_clockwrclock.
