Update.
* sysdeps/unix/sysv/linux/ia64/pthread_once.c: Use __builtin_expect. Use __lll_add instead of spelling it out. Use protected symbol names. * sysdeps/unix/sysv/linux/ia64/sem_post.c: Use __builtin_expect. Use __lll_add. * sysdeps/unix/sysv/linux/ia64/lowlevellock.h (__lll_compare_and_swap): Renamed from lll_compare_and_swap. Use new name where necessary. (__lll_add): Defined. (__lll_dec_if_positive): Defined. (__lll_test_and_set): Defined. * sysdeps/ia64/pthread_spin_init.c: Removed. * sysdeps/unix/sysv/linux/ia64/lowlevelmutex.c: Removed. * sysdeps/unix/sysv/linux/ia64/sem_trywait.c: Removed. * sysdeps/unix/sysv/linux/ia64/sem_wait.c: Removed. * sysdeps/unix/sysv/linux/ia64/lowlevellock.c: Removed. * sysdeps/unix/sysv/linux/ia64/libc-lowlevellock.c: Removed. * sysdeps/unix/sysv/linux/ia64/libc-lowlevelmutex.c: Removed. * sysdeps/unix/sysv/linux/ia64/sem_timedwait.c: Removed.
