From fdbb0d98bae4c3f62e5893b9194456cae61bd1d2 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Mon, 2 Nov 2015 12:14:35 -0200 Subject: posix: Consolidate Linux fsync syscall This patch consolidates the fsync Linux syscall generation on sysdeps/unix/sysv/linux/fsync.c. It basically removes it from architectures auto-generation list. For arm it also removes the __errno_location call since fsync is not called with SYSCALL_CANCEL with call arch-specific INLINE_SYSCALL macro which in turn will call __set_errno macro (and setting errno directly). 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-fsync.c): New flag. * nptl/Makefile (CFLAGS-fsync.c): Likewise. * sysdeps/unix/syscalls.list (fsync): Remove from auto-generation syscall list. * sysdeps/unix/sysv/linux/fsync.c: New file. * sysdeps/unix/sysv/linux/arm/localplt.data [libpthread.so] (__errno_location): Remove. --- misc/Makefile | 1 + 1 file changed, 1 insertion(+) (limited to 'misc/Makefile') diff --git a/misc/Makefile b/misc/Makefile index a777ece4a5..2db1fd8397 100644 --- a/misc/Makefile +++ b/misc/Makefile @@ -110,6 +110,7 @@ CFLAGS-err.c = -fexceptions CFLAGS-tst-tsearch.c = $(stack-align-test-flags) CFLAGS-msync.c = -fexceptions -fasynchronous-unwind-tables CFLAGS-fdatasync.c = -fexceptions -fasynchronous-unwind-tables +CFLAGS-fsync.c = -fexceptions -fasynchronous-unwind-tables # Called during static library initialization, so turn stack-protection # off for non-shared builds. -- cgit 1.4.1
