Update.
2000-05-05 H.J. Lu <hjl@gnu.org>
* sysdeps/ia64/pt-machine.h (__compare_and_swap): Change it to
have acquire semantics.
(__compare_and_swap_with_release_semantics): New inline
function.
(HAS_COMPARE_AND_SWAP_WITH_RELEASE_SEMANTICS): New macro.
2000-01-28 Hans Boehm <hboehm@exch.hpl.hp.com>
* manager.c: Fix the problem with signals at startup.
Change the way that thread stacks are allocated on IA64.
Clean up some of the guard page allocation stuff.
1999-12-19 H.J. Lu <hjl@gnu.org>
* internals.h (page_roundup): New.
* attr.c (__pthread_attr_setguardsize); Use page_roundup
instead of roundup.
* manager.c (pthread_allocate_stack): Make sure guardaddr is
page aligned with page_roundup if NEED_SEPARATE_REGISTER_STACK
is define.
1999-12-17 Hans Boehm <hboehm@exch.hpl.hp.com>
* manager.c (pthread_allocate_stack): Unmap the stack top
if failed to map the stack bottom.
Fix the guard page.
(pthread_free): Fix the guard page.
* pthread.c (pthread_initialize): Set rlimit correctly for
NEED_SEPARATE_REGISTER_STACK.
1999-12-16 H.J. Lu <hjl@gnu.org>
* pthread.c (__pthread_initialize_manager): Pass
__pthread_manager_thread_bos instead of
__pthread_manager_thread_tos to __clone2.
1999-12-16 H.J. Lu <hjl@gnu.org>
* manager.c (pthread_allocate_stack): Correct the calculation
of "new_thread_bottom". Remove MAP_GROWSDOWN from mmap for
stack bottom.

* sysdeps/ia64/pt-machine.h (__compare_and_swap): Added a stop
bit after setting ar.ccv.
1999-12-12 H.J. Lu <hjl@gnu.org>
* manager.c (pthread_allocate_stack): Make the starting
address of the stack bottom page aligned. FIXME: it may
need changes in other places.
(pthread_handle_create): Likewise.
