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. --- libobjc/objc-foreach.c | 51 ++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 51 insertions(+) create mode 100644 libobjc/objc-foreach.c (limited to 'libobjc/objc-foreach.c') diff --git a/libobjc/objc-foreach.c b/libobjc/objc-foreach.c new file mode 100644 index 000000000..911206118 --- /dev/null +++ b/libobjc/objc-foreach.c @@ -0,0 +1,51 @@ +/* GNU Objective C Runtime 'fast enumeration' implementation + Copyright (C) 2010 Free Software Foundation, Inc. + Contributed by Nicola Pero + +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.
