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/testsuite/20_util/function/1.cc | 94 +++++++++++++ libstdc++-v3/testsuite/20_util/function/2.cc | 78 +++++++++++ libstdc++-v3/testsuite/20_util/function/3.cc | 78 +++++++++++ libstdc++-v3/testsuite/20_util/function/4.cc | 82 ++++++++++++ libstdc++-v3/testsuite/20_util/function/43397.cc | 78 +++++++++++ libstdc++-v3/testsuite/20_util/function/48541.cc | 40 ++++++ libstdc++-v3/testsuite/20_util/function/5.cc | 107 +++++++++++++++ libstdc++-v3/testsuite/20_util/function/6.cc | 82 ++++++++++++ libstdc++-v3/testsuite/20_util/function/7.cc | 82 ++++++++++++ libstdc++-v3/testsuite/20_util/function/8.cc | 148 +++++++++++++++++++++ libstdc++-v3/testsuite/20_util/function/9.cc | 55 ++++++++ .../testsuite/20_util/function/assign/move.cc | 50 +++++++ .../20_util/function/assign/move_target.cc | 47 +++++++ .../testsuite/20_util/function/cmp/cmp_neg.cc | 32 +++++ .../testsuite/20_util/function/cons/move.cc | 48 +++++++ .../testsuite/20_util/function/cons/move_target.cc | 46 +++++++ .../testsuite/20_util/function/invoke/move_only.cc | 61 +++++++++ .../20_util/function/null_pointer_comparisons.cc | 44 ++++++ .../requirements/explicit_instantiation.cc | 26 ++++ 19 files changed, 1278 insertions(+) create mode 100644 libstdc++-v3/testsuite/20_util/function/1.cc create mode 100644 libstdc++-v3/testsuite/20_util/function/2.cc create mode 100644 libstdc++-v3/testsuite/20_util/function/3.cc create mode 100644 libstdc++-v3/testsuite/20_util/function/4.cc create mode 100644 libstdc++-v3/testsuite/20_util/function/43397.cc create mode 100644 libstdc++-v3/testsuite/20_util/function/48541.cc create mode 100644 libstdc++-v3/testsuite/20_util/function/5.cc create mode 100644 libstdc++-v3/testsuite/20_util/function/6.cc create mode 100644 libstdc++-v3/testsuite/20_util/function/7.cc create mode 100644 libstdc++-v3/testsuite/20_util/function/8.cc create mode 100644 libstdc++-v3/testsuite/20_util/function/9.cc create mode 100644 libstdc++-v3/testsuite/20_util/function/assign/move.cc create mode 100644 libstdc++-v3/testsuite/20_util/function/assign/move_target.cc create mode 100644 libstdc++-v3/testsuite/20_util/function/cmp/cmp_neg.cc create mode 100644 libstdc++-v3/testsuite/20_util/function/cons/move.cc create mode 100644 libstdc++-v3/testsuite/20_util/function/cons/move_target.cc create mode 100644 libstdc++-v3/testsuite/20_util/function/invoke/move_only.cc create mode 100644 libstdc++-v3/testsuite/20_util/function/null_pointer_comparisons.cc create mode 100644 libstdc++-v3/testsuite/20_util/function/requirements/explicit_instantiation.cc (limited to 'libstdc++-v3/testsuite/20_util/function') diff --git a/libstdc++-v3/testsuite/20_util/function/1.cc b/libstdc++-v3/testsuite/20_util/function/1.cc new file mode 100644 index 000000000..89a22542b --- /dev/null +++ b/libstdc++-v3/testsuite/20_util/function/1.cc @@ -0,0 +1,94 @@ +// { dg-options "-std=gnu++0x" } +// 2005-01-15 Douglas Gregor +// +// Copyright (C) 2005, 2009 Free Software Foundation, Inc. +// +// This file is part of the GNU ISO C++ Library.
