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. * misc/Makefile (CFLAGS-msync.c): New rule. * nptl/Makefile (CFLAGS-msync.c): Likewise. * sysdeps/unix/syscalls.list: Remove msync from auto-generation list. * sysdeps/unix/sysv/linux/msync.c: New file. --- ChangeLog | 5 +++++ misc/Makefile | 1 + nptl/Makefile | 1 + sysdeps/unix/syscalls.list | 1 - sysdeps/unix/sysv/linux/msync.c | 26 ++++++++++++++++++++++++++ 5 files changed, 33 insertions(+), 1 deletion(-) create mode 100644 sysdeps/unix/sysv/linux/msync.c diff --git a/misc/Makefile b/misc/Makefile index 91e425b..8536255 100644 --- a/misc/Makefile +++ b/misc/Makefile @@ -108,6 +108,7 @@ CFLAGS-getsysstats.c = -fexceptions CFLAGS-getusershell.c = -fexceptions CFLAGS-err.c = -fexceptions CFLAGS-tst-tsearch.c = $(stack-align-test-flags) +CFLAGS-msync.c = -fexceptions # Called during static library initialization, so turn stack-protection # off for non-shared builds. diff --git a/nptl/Makefile b/nptl/Makefile index cdf69bd..875ab3d 100644 --- a/nptl/Makefile +++ b/nptl/Makefile @@ -217,6 +217,7 @@ CFLAGS-close.c = -fexceptions -fasynchronous-unwind-tables CFLAGS-read.c = -fexceptions -fasynchronous-unwind-tables CFLAGS-write.c = -fexceptions -fasynchronous-unwind-tables CFLAGS-nanosleep.c = -fexceptions -fasynchronous-unwind-tables +CFLAGS-msync.c = -fexceptions -fasynchronous-unwind-tables CFLAGS-pt-system.c = -fexceptions diff --git a/sysdeps/unix/syscalls.list b/sysdeps/unix/syscalls.list index 2254c76..c4135d8 100644 --- a/sysdeps/unix/syscalls.list +++ b/sysdeps/unix/syscalls.list @@ -45,7 +45,6 @@ madvise - madvise i:pii __madvise madvise mkdir - mkdir i:si __mkdir mkdir mmap - mmap b:aniiii __mmap mmap mprotect - mprotect i:aii __mprotect mprotect -msync - msync Ci:aii __libc_msync msync munmap - munmap i:ai __munmap munmap open - open Ci:siv __libc_open __open open profil - profil i:piii __profil profil diff --git a/sysdeps/unix/sysv/linux/msync.c b/sysdeps/unix/sysv/linux/msync.c new file mode 100644 index 0000000..28aba11 --- /dev/null +++ b/sysdeps/unix/sysv/linux/msync.c @@ -0,0 +1,26 @@ +/* Linux synchronize a file with a memory map 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.
