+ nptl: Add POSIX-proposed pthread_cond_clockwait which behaves just
+ like pthread_cond_timedwait except it always measures abstime
+ against the supplied clockid.
+ * nptl/Makefile: Add tst-cond26 and tst-cond27
+ * nptl/Versions (GLIBC_2.30): Add pthread_cond_clockwait
+ * sysdeps/nptl/pthread.h: Likewise
+ * nptl/forward.c: Add __pthread_cond_clockwait
+ * nptl/forward.c: Likewise
+ * nptl/pthreadP.h: Likewise
+ * sysdeps/nptl/pthread-functions.h: Likewise
+ * nptl/pthread_cond_wait.c (__pthread_cond_wait_common): Add
+ clockid parameter and comment describing why we don't need to check
+ its value. Use that value when calling
+ futex_abstimed_wait_cancelable rather than reading the clock from
+ the flags. (__pthread_cond_wait): Pass unused clockid parameter.
+ (__pthread_cond_timedwait): Read clock from flags and pass it to
+ __pthread_cond_wait_common. (__pthread_cond_clockwait): Add new
+ function with weak alias from pthread_cond_clockwait.
+ * sysdeps/unix/sysv/linux/aarch64/libpthread.abilist (GLIBC_2.30): Likewise.

+ * nptl/tst-cond11.c (run_test): Support testing
+ pthread_cond_clockwait too by using a special magic
+ CLOCK_USE_ATTR_CLOCK value to determine whether to call
+ pthread_cond_timedwait or pthread_cond_clockwait. (do_test): Pass
+ CLOCK_USE_ATTR_CLOCK for existing tests, and add new tests using
+ all combinations of CLOCK_MONOTONIC and CLOCK_REALTIME.
+ * ntpl/tst-cond26.c: New test for passing unsupported and invalid
+ clocks to pthread_cond_clockwait.
+ * nptl/tst-cond27.c: Add test similar to tst-cond5.c, but using
+ struct timespec and pthread_cond_clockwait.
+ * manual/threads.texi: Document pthread_cond_clockwait.
+
nptl: Add POSIX-proposed sem_clockwait which behaves just like
sem_timedwait, but measures abstime against the specified clock.
* nptl/sem_waitcommon.c (do_futex_wait, __new_sem_wait_slow): Add
@code{CLOCK_MONOTONIC} or @code{CLOCK_REALTIME}.

+@c If exactly the same function with arguments is called from a signal
+@c handler that interrupts between the mutex unlock and sleep then it
+@c will unlock the mutex twice resulting in undefined behaviour. Keep
+@c in mind that the unlock and sleep are only atomic with respect to other
+@c threads (really a happens-after relationship for pthread_cond_broadcast
+@c and pthread_cond_signal).
+@c In the AC case we would cancel the thread and the mutex would remain
+@c locked and we can't recover from that.
+Behaves like @code{pthread_cond_timedwait} except the time @var{abstime} is
+measured against the clock specified by @var{clockid} rather than the clock
+specified or defaulted when @code{pthread_cond_init} was called. Currently,
