From 54da5be39c868b55c234c23bb38eb42babc084d7 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Mon, 14 Aug 1995 22:49:23 +0000 Subject: Mon Aug 14 16:51:13 1995 Roland McGrath * hurd/thread-cancel.c: New file. * sysdeps/mach/hurd/i386/trampoline.c (_hurd_setup_sighandler): In rpc_wait case, frob mach_msg args to set timeout on receive. (_hurdsig_rcv_interrupted_p): Function removed. * sysdeps/mach/hurd/alpha/trampoline.c: Likewise. * sysdeps/mach/hurd/hppa/trampoline.c: Likewise. * sysdeps/mach/hurd/mips/trampoline.c: Likewise. * hurd/intr-msg.c: New file. * hurd/hurd/signal.h (struct hurd_sigstate): New member `cancel'. (_hurdsig_rcv_interrupted_p): Declaration removed. (HURD_EINTR_RPC): Macro removed. (_hurd_longjmp_thread_state, _hurd_interrupted_rpc_timeout): Declare these. * hurd/intr-rpc.h: New file. * hurd/intr-rpc.defs: Just import intr-rpc.h. * hurd/hurdsig.c (_hurd_interrupted_rpc_timeout): New variable. (interrupted_reply_port_location): Take new flag arg; only catch faults if it's set. (abort_rpcs): Rename to _hurdsig_abort_rpcs; take same new flag arg. No longer use _hurdsig_rcv_interrupted_p; instead compare PC to &_hurd_intr_rpc_msg_in_trap. If before it, mutate state to simulate MACH_SEND_INTERRUPTED return; on it, interrupt the operation. All callers changed. * hurd/hurd.h (hurd_thread_cancel, hurd_check_cancel): Declare these. * hurd/Makefile (distribute): Remove intr-rpc.awk. (sig): Add thread-cancel. (transform-user-stub, transform-user-stub-output): Variables removed. * sysdeps/mach/hurd/dl-sysdep.c: Change all RPCs from `__hurd_intr_rpc_*' to `__*'. (_hurd_intr_rpc_mach_msg): New function. (_hurd_thread_sigstate): Function removed. * sysdeps/mach/hurd/ioctl.c: Use _hurd_intr_rpc_mach_msg function, instead of __mach_msg inside HURD_EINTR_RPC macro. * sysdeps/generic/morecore.c [__GNU_LIBRARY__]: Declare `__sbrk' to take ptrdiff_t arg. * sysdeps/mach/hurd/fork.c: Remove _hurd_longjmp_thread_state decl. * sysdeps/mach/hurd/kill.c (kill_pid): Don't make `inline'. * libc-symbols.h [GCC >= 2.7] (strong_alias, weak_symbol, weak_alias): Use `extern' storage class. --- sysdeps/mach/hurd/fork.c | 3 --- 1 file changed, 3 deletions(-) (limited to 'sysdeps/mach/hurd/fork.c') diff --git a/sysdeps/mach/hurd/fork.c b/sysdeps/mach/hurd/fork.c index 8e625b8e5e..b8b15743cd 100644 --- a/sysdeps/mach/hurd/fork.c +++ b/sysdeps/mach/hurd/fork.c @@ -27,9 +27,6 @@ Cambridge, MA 02139, USA. */ #include #include "hurdmalloc.h" /* XXX */ -extern void _hurd_longjmp_thread_state (struct machine_thread_state *, - jmp_buf env, int value); - /* Things that want to be locked while forking. */ struct -- cgit v1.2.3
