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. |
