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. --- ports/sysdeps/tile/crti.S | 124 ---------------------------------------------- 1 file changed, 124 deletions(-) delete mode 100644 ports/sysdeps/tile/crti.S (limited to 'ports/sysdeps/tile/crti.S') diff --git a/ports/sysdeps/tile/crti.S b/ports/sysdeps/tile/crti.S deleted file mode 100644 index 55eb238..0000000 --- a/ports/sysdeps/tile/crti.S +++ /dev/null @@ -1,124 +0,0 @@ -/* Special .init and .fini section support for tile. - Copyright (C) 2012-2014 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. - - In addition to the permissions in the GNU Lesser General Public - License, the Free Software Foundation gives you unlimited - permission to link the compiled version of this file with other - programs, and to distribute those programs without any restriction - coming from the use of this file.
