Update.
2004-06-13 Kaz Kojima <kkojima@rr.iij4u.or.jp>
* sysdeps/unix/sysv/linux/sh/bits/pthreadtypes.h (pthread_cond_t):
Add __data.__futex field, reshuffle __data.__clock.
* sysdeps/unix/sysv/linux/sh/pthread_cond_signal.S
(__pthread_cond_signal): Increment __futex at the same time as
__wakeup_seq or __total_seq. Pass address of __futex instead of
address of low 32-bits of __wakeup_seq to futex syscall.
* sysdeps/unix/sysv/linux/sh/pthread_cond_wait.S
(__pthread_cond_wait): Likewise. Pass __futex value from before
releasing internal lock to FUTEX_WAIT.
* sysdeps/unix/sysv/linux/sh/pthread_cond_timedwait.S
(__pthread_cond_timedwait): Likewise.
* sysdeps/unix/sysv/linux/sh/pthread_cond_broadcast.S
(FUTEX_CMP_REQUEUE): Define.
(__pthread_cond_broadcast): Set __futex to 2 * __total_seq.
Use FUTEX_CMP_REQUEUE operation instead of FUTEX_REQUEUE.
Pass __futex value from before the unlock and __futex address instead
of address of low 32-bits of __wakeup_seq to futex syscall.
Fallback to FUTEX_WAKE all on any errors.
