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. --- libstdc++-v3/include/backward/auto_ptr.h | 295 ++++++ libstdc++-v3/include/backward/backward_warning.h | 61 ++ libstdc++-v3/include/backward/binders.h | 172 ++++ libstdc++-v3/include/backward/hash_fun.h | 171 ++++ libstdc++-v3/include/backward/hash_map | 600 +++++++++++ libstdc++-v3/include/backward/hash_set | 568 +++++++++++ libstdc++-v3/include/backward/hashtable.h | 1149 ++++++++++++++++++++++ libstdc++-v3/include/backward/strstream | 185 ++++ 8 files changed, 3201 insertions(+) create mode 100644 libstdc++-v3/include/backward/auto_ptr.h create mode 100644 libstdc++-v3/include/backward/backward_warning.h create mode 100644 libstdc++-v3/include/backward/binders.h create mode 100644 libstdc++-v3/include/backward/hash_fun.h create mode 100644 libstdc++-v3/include/backward/hash_map create mode 100644 libstdc++-v3/include/backward/hash_set create mode 100644 libstdc++-v3/include/backward/hashtable.h create mode 100644 libstdc++-v3/include/backward/strstream (limited to 'libstdc++-v3/include/backward') diff --git a/libstdc++-v3/include/backward/auto_ptr.h b/libstdc++-v3/include/backward/auto_ptr.h new file mode 100644 index 000000000..e86876510 --- /dev/null +++ b/libstdc++-v3/include/backward/auto_ptr.h @@ -0,0 +1,295 @@ +// auto_ptr implementation -*- C++ -*- + +// Copyright (C) 2007, 2008, 2009, 2010, 2011 Free Software Foundation, Inc. +// +// This file is part of the GNU ISO C++ Library.
