Update.
2003-05-28 Kaz Kojima <kkojima@rr.iij4u.or.jp> * sysdeps/sh/tcb-offsets.sym: Define MUTEX_FUTEX. * sysdeps/unix/sysv/linux/sh/bits/pthreadtypes.h (pthread_cond_t): Add __mutex field. * sysdeps/unix/sysv/linux/sh/lowlevellock.h (SYSCALL_WITH_INST_PAD): Define. (lll_futex_wait, lll_futex_wake): Define. * sysdeps/unix/sysv/linux/sh/sh4/lowlevellock.h: New file. * sysdeps/unix/sysv/linux/sh/pthread_cond_broadcast.S: Try using FUTEX_REQUEUE instead of FUTEX_WAIT. * sysdeps/unix/sysv/linux/sh/pthread_cond_signal.S: Likewise. * sysdeps/unix/sysv/linux/sh/pthread_cond_timedwait.S: Remember mutex which was used in condvar structure. Call __pthread_mutex_cond_lock instead of __pthread_mutex_lock_internal. * sysdeps/unix/sysv/linux/sh/pthread_cond_wait.S: Likewise. * sysdeps/unix/sysv/linux/sh/pthread_rwlock_rdlock.S: Don't include tcb-offsets.h. Read wakeup value in locked region. Use the value of gbr register as THREAD_ID. * sysdeps/unix/sysv/linux/sh/pthread_rwlock_wrlock.S: Likewise. * sysdeps/unix/sysv/linux/sh/pthread_rwlock_timedrdlock.S: Likewise. * sysdeps/unix/sysv/linux/sh/pthread_rwlock_timedwrlock.S: Likewise. * sysdeps/unix/sysv/linux/sh/sem_trywait.S: Remove futex related macros.
