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.
