From cab6e5af9d51d4398522af782e20c743daf37461 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Fri, 11 Nov 2016 14:50:03 -0200 Subject: Consolidate Linux creat implementation This patch consolidates the creat Linux syscall implementation on sysdeps/unix/sysv/linux/creat{64}.c. The changes are: 1. Remove creat{64} from auto-generation syscalls.list. 2. Add a new creat{64}.c implementation. For architectures that define __OFF_T_MATCHES_OFF64_T the default creat64 will create alias to required creat symbols. 3. Use __NR_creat where possible, otherwise use internal open{64} call with expected flags. Checked on i686-linux-gnu, x86_64-linux-gnu, x86_64-linux-gnux32, arch64-linux-gnu, arm-linux-gnueabihf, and powerpc64le-linux-gnu. * io/Makefile (CFLAGS-creat.c): New rule. (CFLAGS-creat64.c): Likewise. * sysdeps/unix/sysv/linux/alpha/creat.c: Remove file. * sysdeps/unix/sysv/linux/generic/creat.c: Likewise. * sysdeps/unix/sysv/linux/wordsize-64/creat64.c: Likewise. * sysdeps/unix/sysv/linux/creat.c: New file. * sysdeps/unix/sysv/linux/creat64.c: Likewise. * sysdeps/unix/sysv/linux/syscalls.list: Remove create from auto-generated list. * sysdeps/unix/sysv/linux/wordsize-64/syscalls.list: Likewise. --- sysdeps/unix/sysv/linux/creat.c | 40 ++++++++++++++++++++++++++++++++++++++++ 1 file changed, 40 insertions(+) create mode 100644 sysdeps/unix/sysv/linux/creat.c (limited to 'sysdeps/unix/sysv/linux/creat.c') diff --git a/sysdeps/unix/sysv/linux/creat.c b/sysdeps/unix/sysv/linux/creat.c new file mode 100644 index 0000000000..31e024838c --- /dev/null +++ b/sysdeps/unix/sysv/linux/creat.c @@ -0,0 +1,40 @@ +/* Linux default implementation for creat. + 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.
