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/mips/generic.md | 105 +++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 105 insertions(+) create mode 100644 gcc/config/mips/generic.md (limited to 'gcc/config/mips/generic.md') diff --git a/gcc/config/mips/generic.md b/gcc/config/mips/generic.md new file mode 100644 index 000000000..d61511f33 --- /dev/null +++ b/gcc/config/mips/generic.md @@ -0,0 +1,105 @@ +;; Generic DFA-based pipeline description for MIPS targets +;; Copyright (C) 2004, 2005, 2007 Free Software Foundation, Inc. +;; +;; 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.
