2008-12-11 Neal H. Walfield <neal@gnu.org>
Update to new RPC interfaces.
* _exit.c (_exit): Update use of rm_folio_object_alloc to be
consistent with the new interface.
* backtrace.c (RA) [!RM_INTERN]: Set up a fault catch handler to
avoid gratuitously faulting.
(backtrace) [!RM_INTERN]: Set up a jump buffer. Jump to it on a
fault.
(backtrace_print): Use s_printf, not printf.
* ia32-crt0.S (STACK_SIZE): Increase to 128 kb.
* process-spawn.c (process_spawn): Don't use a capability slot to
identify the root of the new thread's address space, allocate a
thread object. Allocate messengers for the new thread and save
them in STARTUP_DATA->MESSENGERS.
* s_printf.c (io_buffer_flush): Use the debug output interface.
(s_putchar): Don't call rm_write but use io_buffer_flush.

2008-12-11 Neal H. Walfield <neal@gnu.org>
Update to new RPC interfaces, IPC semantics.
* sysdeps/viengoos/bits/pthread-np.h: Include <hurd/exceptions.h>.
(pthread_hurd_utcb_np): New declaration.
* sysdeps/viengoos/pt-hurd-utcb-np.c: New file.
* Makefile.am (libpthread_a_SOURCES): Add pt-hurd-utcb.c.
* sysdeps/viengoos/pt-sysdep.h (EXCEPTION_AREA_SIZE): Don't
define.
(EXCEPTION_AREA_SIZE_LOG2): Likewise.
(EXCEPTION_PAGE): Likewise.
(PTHREAD_SYSDEP_MEMBERS): Remove fields exception_area, and
exception_area_va. Add fields utcb and lock_message_buffer.
* sysdeps/viengoos/pt-thread-alloc.c: Include
<hurd/message-buffer.h>.
(__pthread_thread_alloc): Initialize thread->lock_message_buffer.
When executed the first time, set the thread's L4 user-defined
handler. Initialize THREAD->UTCB with the thread's current utcb.
Set HURD_UTCB to PTHREAD_HURD_UTCB_NP. For subsequent threads,
don't manually set up the activation area. Instead, call
hurd_activation_state_alloc.
* sysdeps/viengoos/pt-thread-dealloc.c: Include
<hurd/message-buffer.h>.
(__pthread_thread_dealloc): Call __pthread_thread_halt. Don't
manually clean up the activation area. Instead, call
hurd_activation_state_free. Free THREAD->LOCK_MESSAGE_BUFFER.
* sysdeps/viengoos/ia32/pt-setup.c (stack_setup): Pre-fault the
first four pages of the new stack.
(__pthread_setup): Don't set up the activation area.
* sysdeps/viengoos/pt-wakeup.c (__pthread_wakeup): Use
futex_wake_using with the calling thread's lock messenger.
* sysdeps/viengoos/pt-block.c (__pthread_block): Use
futex_wait_using and provide THREAD->LOCK_MESSAGE_BUFFER as the
message buffer.
* sysdeps/viengoos/pt-thread-start.c (__pthread_thread_start):
Don't set the first thread's L4 user-defined handler here.
(__pthread_thread_start): Update use of rm_thread_exregs according
to be consistent with new interface.
* sysdeps/viengoos/pt-thread-halt.c (__pthread_thread_halt): If
THREAD is the current thread, call vg_suspend.
* sysdeps/viengoos/pt-setactivity-np.c (pthread_setactivity_np):
Update use of rm_thread_exregs according to be consistent with new
interface.
* sysdeps/viengoos/ia32/signal-dispatch-lowlevel.c
(signal_dispatch_lowlevel): Use __builtin_frame_address to get the
current stack frame's start. Update use of rm_thread_exregs
according to be consistent with new interface.

2008-12-12 Neal H. Walfield <neal@gnu.org>
Update to new RPC interfaces.
* ruth.c (main): Update use of rm_folio_alloc,
rm_folio_object_alloc, rm_thread_exregs, rm_activity_policy,
rm_activity_info. Replace use of rm_thread_wait_object_destroy
with rm_object_reply_on_destruction. Replace use of `struct
exception_info' with `struct activation_fault_info'. Fix signal
test's use of condition variables to not rely on the scheduler.
When checking deallocation code, set up a fault handler to
programmatically determine success.
