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/rs6000/476.md | 142 +++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 142 insertions(+) create mode 100644 gcc/config/rs6000/476.md (limited to 'gcc/config/rs6000/476.md') diff --git a/gcc/config/rs6000/476.md b/gcc/config/rs6000/476.md new file mode 100644 index 000000000..3f50bafa0 --- /dev/null +++ b/gcc/config/rs6000/476.md @@ -0,0 +1,142 @@ +;; Scheduling description for IBM PowerPC 476 processor. +;; Copyright (C) 2009 +;; Free Software Foundation, Inc. +;; Contributed by Peter Bergner (bergner@vnet.ibm.com). +;; +;; 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.
