Update.
2000-07-27 Jes Sorensen <jes@linuxcare.com> * linuxthreads/sysdeps/ia64/pspinlock.c (__pthread_spin_lock): Add load of spin lock to prime the cache before the atomic compare and exchange operation (cmpxchg4). This avoids the spinning on the cmpxchg4 instruction and reduces movement of the cache line back and forth between the processors (explanation by Asis K. Mallick from Intel). This basically makes the implementation operate the same as the Linux kernel implementation. * linuxthreads/shlib-versions: Use GLIBC_2_2 for Linux/ia64. * linuxthreads/sysdeps/ia64/pspinlock.c: New file.
