From cdba937662b16fc3685a8115f21e73f21330a44c Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Thu, 3 Dec 2020 11:28:58 -0300 Subject: nptl: Move Linux pthread_kill to nptl The nptl already expects a Linux syscall internally. Also __is_internal_signal is used and the DEBUGGING_P check is removed. Checked on x86_64-linux-gnu. --- sysdeps/unix/sysv/linux/pthread_kill.c | 57 ---------------------------------- 1 file changed, 57 deletions(-) delete mode 100644 sysdeps/unix/sysv/linux/pthread_kill.c (limited to 'sysdeps/unix') diff --git a/sysdeps/unix/sysv/linux/pthread_kill.c b/sysdeps/unix/sysv/linux/pthread_kill.c deleted file mode 100644 index 13560e6511..0000000000 --- a/sysdeps/unix/sysv/linux/pthread_kill.c +++ /dev/null @@ -1,57 +0,0 @@ -/* Copyright (C) 2002-2021 Free Software Foundation, Inc. - This file is part of the GNU C Library. - Contributed by Ulrich Drepper , 2002. - - The GNU C Library is free software; you can redistribute it and/or - modify it under the terms of the GNU Lesser General Public - License as published by the Free Software Foundation; either - version 2.1 of the License, or (at your option) any later version. - - The GNU C Library is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
