From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- gcc/config/rs6000/crtresxgpr.asm | 124 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 124 insertions(+) create mode 100644 gcc/config/rs6000/crtresxgpr.asm (limited to 'gcc/config/rs6000/crtresxgpr.asm') diff --git a/gcc/config/rs6000/crtresxgpr.asm b/gcc/config/rs6000/crtresxgpr.asm new file mode 100644 index 000000000..451b2b69d --- /dev/null +++ b/gcc/config/rs6000/crtresxgpr.asm @@ -0,0 +1,124 @@ +/* + * Special support for eabi and SVR4 + * + * Copyright (C) 1995, 1996, 1998, 2000, 2001, 2008, 2009 + * Free Software Foundation, Inc. + * Written By Michael Meissner + * 64-bit support written by David Edelsohn + * + * This file is free software; you can redistribute it and/or modify it + * under the terms of the GNU General Public License as published by the + * Free Software Foundation; either version 3, or (at your option) any + * later version. + * + * This file 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.
