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/18_support/exception_ptr/40296.cc | 30 ++++ .../18_support/exception_ptr/current_exception.cc | 91 ++++++++++ .../testsuite/18_support/exception_ptr/lifespan.cc | 189 +++++++++++++++++++++ .../18_support/exception_ptr/make_exception_ptr.cc | 38 +++++ .../testsuite/18_support/exception_ptr/move.cc | 45 +++++ .../18_support/exception_ptr/requirements.cc | 60 +++++++ .../18_support/exception_ptr/requirements_neg.cc | 33 ++++ .../18_support/exception_ptr/rethrow_exception.cc | 114 +++++++++++++ 8 files changed, 600 insertions(+) create mode 100644 libstdc++-v3/testsuite/18_support/exception_ptr/40296.cc create mode 100644 libstdc++-v3/testsuite/18_support/exception_ptr/current_exception.cc create mode 100644 libstdc++-v3/testsuite/18_support/exception_ptr/lifespan.cc create mode 100644 libstdc++-v3/testsuite/18_support/exception_ptr/make_exception_ptr.cc create mode 100644 libstdc++-v3/testsuite/18_support/exception_ptr/move.cc create mode 100644 libstdc++-v3/testsuite/18_support/exception_ptr/requirements.cc create mode 100644 libstdc++-v3/testsuite/18_support/exception_ptr/requirements_neg.cc create mode 100644 libstdc++-v3/testsuite/18_support/exception_ptr/rethrow_exception.cc (limited to 'libstdc++-v3/testsuite/18_support/exception_ptr') diff --git a/libstdc++-v3/testsuite/18_support/exception_ptr/40296.cc b/libstdc++-v3/testsuite/18_support/exception_ptr/40296.cc new file mode 100644 index 000000000..933f41369 --- /dev/null +++ b/libstdc++-v3/testsuite/18_support/exception_ptr/40296.cc @@ -0,0 +1,30 @@ +// { dg-do compile } +// { dg-options "-std=gnu++0x" } +// { dg-require-atomic-builtins "" } + +// Copyright (C) 2009 Free Software Foundation, Inc. +// +// This file is part of the GNU ISO C++ Library.
