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/profile.h | 47 +++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 47 insertions(+) create mode 100644 gcc/profile.h (limited to 'gcc/profile.h') diff --git a/gcc/profile.h b/gcc/profile.h new file mode 100644 index 000000000..fe3c2f997 --- /dev/null +++ b/gcc/profile.h @@ -0,0 +1,47 @@ +/* Header file for minimum-cost maximal flow routines used to smooth basic + block and edge frequency counts. + Copyright (C) 2008 + Free Software Foundation, Inc. + Contributed by Paul Yuan (yingbo.com@gmail.com) + and Vinodha Ramasamy (vinodha@google.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.
