From efc6b2dbc47231dee7a7ac39beec808deb4e4d1f Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Fri, 26 Jun 2020 09:29:11 -0300 Subject: linux: Implement pipe in terms of __NR_pipe2 The syscall pipe2 was added in linux 2.6.27 and glibc requires linux 3.2.0. The patch removes the arch-specific implementation for alpha, ia64, mips, sh, and sparc which requires a different kernel ABI than the usual one. Checked on x86_64-linux-gnu and with a build for the affected ABIs. --- sysdeps/unix/sysv/linux/sparc/sparc32/pipe.S | 38 ---------------------------- 1 file changed, 38 deletions(-) delete mode 100644 sysdeps/unix/sysv/linux/sparc/sparc32/pipe.S (limited to 'sysdeps/unix/sysv/linux/sparc/sparc32') diff --git a/sysdeps/unix/sysv/linux/sparc/sparc32/pipe.S b/sysdeps/unix/sysv/linux/sparc/sparc32/pipe.S deleted file mode 100644 index 0fa155fa61..0000000000 --- a/sysdeps/unix/sysv/linux/sparc/sparc32/pipe.S +++ /dev/null @@ -1,38 +0,0 @@ -/* Copyright (C) 1997-2021 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.
