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/ia64/crtfastmath.c | 34 ++++++++++++++++++++++++++++++++++ 1 file changed, 34 insertions(+) create mode 100644 gcc/config/ia64/crtfastmath.c (limited to 'gcc/config/ia64/crtfastmath.c') diff --git a/gcc/config/ia64/crtfastmath.c b/gcc/config/ia64/crtfastmath.c new file mode 100644 index 000000000..0decd2a3f --- /dev/null +++ b/gcc/config/ia64/crtfastmath.c @@ -0,0 +1,34 @@ +/* Copyright (C) 2001, 2005, 2009 Free Software Foundation, Inc. + Contributed by David Mosberger . + + This file is part of GCC. + + GCC 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. + + GCC 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.
