From ecade1cb0b9d5139498ccd7a5d4aa4c1cc870231 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Mon, 2 Nov 2015 11:13:24 -0200 Subject: linux: Consolidate Linux vmsplice syscall This patch consolidates the vmsplice Linux syscall generation on sysdeps/unix/sysv/linux/vmsplice.c. It basically removes it from architectures auto-generation list. Checked on i686-linux-gnu, x86_64-linux-gnu, x86_64-linux-gnux32, arch64-linux-gnu, arm-linux-gnueabihf, powerpc64le-linux-gnu, sparc64-linux-gnu, and sparcv9-linux-gnu. * sysdeps/unix/sysv/linux/Makefile (CFLAGS-vmsplice.c): New flag. * sysdeps/unix/sysv/linux/syscalls.list (vmsplice): Remove from auto-generation syscall list. * sysdeps/unix/sysv/linux/vmsplice.c: New file. * misc/Makefile (CFLAGS-vmsplice.c): New rule. --- sysdeps/unix/sysv/linux/Makefile | 2 +- sysdeps/unix/sysv/linux/syscalls.list | 1 - sysdeps/unix/sysv/linux/vmsplice.c | 27 +++++++++++++++++++++++++++ 3 files changed, 28 insertions(+), 2 deletions(-) create mode 100644 sysdeps/unix/sysv/linux/vmsplice.c (limited to 'sysdeps') diff --git a/sysdeps/unix/sysv/linux/Makefile b/sysdeps/unix/sysv/linux/Makefile index 9388623345..7d1f3d3197 100644 --- a/sysdeps/unix/sysv/linux/Makefile +++ b/sysdeps/unix/sysv/linux/Makefile @@ -17,7 +17,7 @@ include $(firstword $(wildcard $(sysdirs:=/sysctl.mk))) sysdep_routines += clone umount umount2 readahead \ setfsuid setfsgid epoll_pwait signalfd \ eventfd eventfd_read eventfd_write prlimit \ - personality epoll_wait tee + personality epoll_wait tee vmsplice CFLAGS-gethostid.c = -fexceptions CFLAGS-tee.c = -fexceptions -fasynchronous-unwind-tables diff --git a/sysdeps/unix/sysv/linux/syscalls.list b/sysdeps/unix/sysv/linux/syscalls.list index c69eff4432..9d7bd658af 100644 --- a/sysdeps/unix/sysv/linux/syscalls.list +++ b/sysdeps/unix/sysv/linux/syscalls.list @@ -72,7 +72,6 @@ swapoff - swapoff i:s __swapoff swapoff unshare EXTRA unshare i:i unshare uselib EXTRA uselib i:s __compat_uselib uselib@GLIBC_2.0:GLIBC_2.23 utime - utime i:sP utime -vmsplice EXTRA vmsplice Ci:iPii vmsplice wait4 - wait4 i:iWiP __wait4 wait4 chown - chown i:sii __libc_chown __chown chown diff --git a/sysdeps/unix/sysv/linux/vmsplice.c b/sysdeps/unix/sysv/linux/vmsplice.c new file mode 100644 index 0000000000..01dac13a51 --- /dev/null +++ b/sysdeps/unix/sysv/linux/vmsplice.c @@ -0,0 +1,27 @@ +/* Splice user pages into a pipe Linux implementation. + Copyright (C) 2017 Free Software Foundation, Inc. + This file is part of the GNU C Library. + + 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.
