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. --- libgfortran/generated/transpose_r4.c | 114 +++++++++++++++++++++++++++++++++++ 1 file changed, 114 insertions(+) create mode 100644 libgfortran/generated/transpose_r4.c (limited to 'libgfortran/generated/transpose_r4.c') diff --git a/libgfortran/generated/transpose_r4.c b/libgfortran/generated/transpose_r4.c new file mode 100644 index 000000000..1748c1d05 --- /dev/null +++ b/libgfortran/generated/transpose_r4.c @@ -0,0 +1,114 @@ +/* Implementation of the TRANSPOSE intrinsic + Copyright 2003, 2005, 2006, 2007, 2009 Free Software Foundation, Inc. + Contributed by Tobias Schlüter + +This file is part of the GNU Fortran 95 runtime library (libgfortran). + +Libgfortran 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 of the License, or (at your option) any later version. + +Libgfortran 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.
