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. --- libc-symbols.h | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'libc-symbols.h') diff --git a/libc-symbols.h b/libc-symbols.h index 951ea61ec2..7cc67a2b7e 100644 --- a/libc-symbols.h +++ b/libc-symbols.h @@ -141,15 +141,15 @@ Cambridge, MA 02139, USA. */ are better clued in to what we are doing. */ #undef strong_alias #define strong_alias(name, aliasname) \ - __typeof (name) aliasname __attribute__ ((alias (#name))); + extern __typeof (name) aliasname __attribute__ ((alias (#name))); #ifdef HAVE_WEAK_SYMBOLS #undef weak_symbol #define weak_symbol(name) \ - __typeof (name) name __attribute__ ((weak)); + extern __typeof (name) name __attribute__ ((weak)); #undef weak_alias #define weak_alias(name, aliasname) \ - __typeof (name) aliasname __attribute__ ((weak, alias (#name))); + extern __typeof (name) aliasname __attribute__ ((weak, alias (#name))); #endif /* HAVE_WEAK_SYMBOLS. */ #endif /* Not ASSEMBLER, and GCC 2.7 or later. */ -- cgit 1.4.1
