2001-05-01 Kaz Kylheku Memory barrier overhaul following line by line inspection. * mutex.c (pthread_once): Missing memory barriers added. * pthread.c (__pthread_wait_for_restart_signal, __pthread_timedsuspend_new, __pthread_restart_new): Added memory barriers ``just in case'' and for documentary value. * spinlock.c (__pthread_release): New inline function for releasing spinlock, to complement __pthread_acquire. Includes memory barrier prior to assignment to spinlock, and __asm __volatile dance to prevent reordering or optimization of the spinlock access. * spinlock.c (__pthread_unlock, __pthread_alt_lock, __pthread_alt_timedlock, __pthread_alt_unlock, __pthread_compare_and_swap): Updated to use new __pthread_release instead of updating spinlock directly. * spinlock.c (__pthread_lock, __pthread_unlock, wait_node_alloc, wait_node_free, wait_node_dequeue, __pthread_alt_lock, __pthread_alt_timedlock, __pthread_alt_unlock, __pthread_acquire): Memory barrier overhaul. Lots of missing memory barriers added, a couple needless ones removed. * spinlock.c (__pthread_compare_and_swap): testandset optimization removed, just calls __pthread_acquire, which has the new read barrier in it before its testandset.

Update.
