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. --- libgcc/config/lm32/_ashlsi3.S | 114 ++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 114 insertions(+) create mode 100644 libgcc/config/lm32/_ashlsi3.S (limited to 'libgcc/config/lm32/_ashlsi3.S') diff --git a/libgcc/config/lm32/_ashlsi3.S b/libgcc/config/lm32/_ashlsi3.S new file mode 100644 index 000000000..1f8f48d93 --- /dev/null +++ b/libgcc/config/lm32/_ashlsi3.S @@ -0,0 +1,114 @@ +# _ashlsi3.S for Lattice Mico32 +# Contributed by Jon Beniston and Richard Henderson. +# +# Copyright (C) 2009 Free Software Foundation, Inc. +# +# 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.
