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/performance/22_locale/is_wchar_t.cc | 78 ++++++++++++++++++++++ 1 file changed, 78 insertions(+) create mode 100644 libstdc++-v3/testsuite/performance/22_locale/is_wchar_t.cc (limited to 'libstdc++-v3/testsuite/performance/22_locale/is_wchar_t.cc') diff --git a/libstdc++-v3/testsuite/performance/22_locale/is_wchar_t.cc b/libstdc++-v3/testsuite/performance/22_locale/is_wchar_t.cc new file mode 100644 index 000000000..6b845507e --- /dev/null +++ b/libstdc++-v3/testsuite/performance/22_locale/is_wchar_t.cc @@ -0,0 +1,78 @@ +// Copyright (C) 2003, 2009 Free Software Foundation, Inc. +// +// This file is part of the GNU ISO C++ Library.
