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. * nptl/Makefile (CFLAGS-nanosleep.c): New rule. * posix/Makefile (CFLAGS-nanosleep.c): Likewise. * sysdeps/unix/sysv/linux/nanosleep.c: New file. * sysdeps/unix/sysv/linux/syscalls.list: Remove nanosleep from auto-generated list. --- ChangeLog | 6 ++++++ nptl/Makefile | 1 + posix/Makefile | 1 + sysdeps/unix/sysv/linux/nanosleep.c | 30 ++++++++++++++++++++++++++++++ sysdeps/unix/sysv/linux/syscalls.list | 1 - 5 files changed, 38 insertions(+), 1 deletion(-) create mode 100644 sysdeps/unix/sysv/linux/nanosleep.c diff --git a/nptl/Makefile b/nptl/Makefile index d39bb50..cdf69bd 100644 --- a/nptl/Makefile +++ b/nptl/Makefile @@ -216,6 +216,7 @@ CFLAGS-sendmsg.c = -fexceptions -fasynchronous-unwind-tables 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-pt-system.c = -fexceptions diff --git a/posix/Makefile b/posix/Makefile index 0025d8a..9f186cd 100644 --- a/posix/Makefile +++ b/posix/Makefile @@ -232,6 +232,7 @@ CFLAGS-execle.os = -fomit-frame-pointer CFLAGS-execl.os = -fomit-frame-pointer CFLAGS-execvp.os = -fomit-frame-pointer CFLAGS-execlp.os = -fomit-frame-pointer +CFLAGS-nanosleep.c = -fexceptions tstgetopt-ARGS = -a -b -cfoobar --required foobar --optional=bazbug \ --none random --col --color --colour diff --git a/sysdeps/unix/sysv/linux/nanosleep.c b/sysdeps/unix/sysv/linux/nanosleep.c new file mode 100644 index 0000000..b352f84 --- /dev/null +++ b/sysdeps/unix/sysv/linux/nanosleep.c @@ -0,0 +1,30 @@ +/* Linux high resolution nanosleep 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.
