From 4372980f5881e7d537a52e3c49588ce116088061 Mon Sep 17 00:00:00 2001 From: Chris Metcalf Date: Mon, 10 Feb 2014 10:54:47 -0500 Subject: Move tilegx, tilepro, and linux-generic from ports to libc. I've moved the TILE-Gx and TILEPro ports to the main sysdeps hierarchy, along with the linux-generic ports infrastructure. Beyond the README update, the move was just git mv ports/sysdeps/tile sysdeps/tile git mv ports/sysdeps/unix/sysv/linux/tile \ sysdeps/unix/sysv/linux/tile git mv ports/sysdeps/unix/sysv/linux/generic \ sysdeps/unix/sysv/linux/generic I updated the relevant ChangeLogs along the lines of the ARM move in commit c6bfe5c4d75 and tested the 64-bit tilegx build to confirm that there were no changes in "objdump -dr" output in the shared objects. --- .../unix/sysv/linux/generic/wordsize-32/pwrite.c | 59 ++++++++++++++++++++++ 1 file changed, 59 insertions(+) create mode 100644 sysdeps/unix/sysv/linux/generic/wordsize-32/pwrite.c (limited to 'sysdeps/unix/sysv/linux/generic/wordsize-32/pwrite.c') diff --git a/sysdeps/unix/sysv/linux/generic/wordsize-32/pwrite.c b/sysdeps/unix/sysv/linux/generic/wordsize-32/pwrite.c new file mode 100644 index 0000000000..909255bb7e --- /dev/null +++ b/sysdeps/unix/sysv/linux/generic/wordsize-32/pwrite.c @@ -0,0 +1,59 @@ +/* Copyright (C) 2011-2014 Free Software Foundation, Inc. + This file is part of the GNU C Library. + Contributed by Chris Metcalf , 2011. + Based on work contributed by Ulrich Drepper , 1997. + + 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.
