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. --- .../testsuite/22_locale/codecvt/in/wchar_t/7.cc | 88 ++++++++++++++++++++++ 1 file changed, 88 insertions(+) create mode 100644 libstdc++-v3/testsuite/22_locale/codecvt/in/wchar_t/7.cc (limited to 'libstdc++-v3/testsuite/22_locale/codecvt/in/wchar_t/7.cc') diff --git a/libstdc++-v3/testsuite/22_locale/codecvt/in/wchar_t/7.cc b/libstdc++-v3/testsuite/22_locale/codecvt/in/wchar_t/7.cc new file mode 100644 index 000000000..9a172d9a7 --- /dev/null +++ b/libstdc++-v3/testsuite/22_locale/codecvt/in/wchar_t/7.cc @@ -0,0 +1,88 @@ +// { dg-require-namedlocale "en_US.UTF-8" } + +// 2003-02-06 Petur Runolfsson + +// Copyright (C) 2003, 2004, 2005, 2006, 2007, 2009 Free Software Foundation +// +// This file is part of the GNU ISO C++ Library.
