* [libcxx] Add <experimental/type_traits> for LFTSEric Fiselier2014-12-197-0/+945

* [libcxx] Allow the use of ccache when running the test suite.Eric Fiselier2014-12-191-12/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: In order to get the bots running quicker I would like to be able to use ccache with the test suite. This patch adds support for running the test suite using ccache. To use ccache pass `--param=use_ccache=true` when running the test suite. ccache will not cache any command that invokes ld, so the build step needs to be split into two separate compile commands. The cost of splitting the build step into two parts when not using ccache seems to be minimal. On my machine I saw a difference of ~5 seconds on a 5 minute test suite run. A full test suite run with ccache generates about 250MB of cached data. I recorded the following times for running the test suite in the following configurations: - no ccache: 340s - initial ccache run: 380s - rerun with ccache (no changes): 53s. - rerun with ccache (<string> changed): 80s - rerun with ccache (<cmath> changed): 169s - rerun with ccache (<valarray> changed): 69s Reviewers: mclow.lists, jroelofs, danalbert Reviewed By: jroelofs Subscribers: cfe-commits Differential Revision: http://reviews.llvm.org/D6647 llvm-svn: 224603

* [libcxx] Add logic to probe compiler in tests.Eric Fiselier2014-12-061-0/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This patch probes the cxx compiler used during testing by getting it to dump its predefined macros. Based on the value of these macros the compiler name and compiler name + version are added to the available features. There are three compiler names: - `clang` - `apple-clang` - `gcc`. The available features added are equivalent to: - `'%s' % compiler_name` - `'%s-%s.%s' % compiler_name, major_version, minor_version` This information can be used to XFAIL tests on different compilers / versions.

* Add support for building and testing libc++ without threads to CMake.Eric Fiselier2014-12-063-11/+32
| | | | | | | | | | | Currently hacks must be used in to configure and build libc++ without threads when using CMake. This patch adds CMake options to enable/disable building with threads and a monotonic clock. This patch also propagates the configuration information to lit so the tests are properly configured as well. llvm-svn: 223591
* libc++: add NaCl and PNaCl support for std::random_deviceJF Bastien2014-12-011-30/+66
| | | | | | | | | | | | | | | | | Summary: The NaCl sandbox doesn't allow opening files under /dev, but it offers an API which provides the same capabilities. This is the same random device emulation that nacl_io performs for POSIX support, but nacl_io is an optional library so libc++ can't assume that device emulation will be performed. Note that NaCl only supports /dev/urandom, not /dev/random. This patch also cleans up some of the preprocessor #endif, and fixes the test for Win32 (it accepts any token, and would therefore never throw regardless of the token provided).

* Add better support for custom test runners.Dan Albert2014-11-241-27/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: I finally got around to merging the many, many changes to lit.cfg into Android's libc++. This patch makes it simpler to actually use a custom configuration and test format. First, I've factored out _build, _run, and _clean methods from _execute_test, since these are the likely parts that will need to be overridden. This is likely a first step in the work jroelofs has been doing with improving cross-compiling test execution. Second, I've added a `configuration_variant` to the config. This entry, if present, is a string that forms the prefix of the class that is to be used to configure the test runner. For example, Android sets `config.configuration_variant = 'Android'`, and this causes an object of type `AndroidConfiguration` to be constructed. As an example of how this will be used, see: https://android-review.googlesource.com/#/c/116022/ Reviewers: jroelofs, mclow.lists, EricWF Reviewed By: EricWF Subscribers: cfe-commits Differential Revision: http://reviews.llvm.org/D6373 llvm-svn: 222698

* Overhaul and separate nullptr_t tests to pass with C++03.Eric Fiselier2014-11-193-34/+95
| | | | | | | | | | | The standard requires that nullptr_t can be reinterpret_cast to an integral type at least the size of nullptr_t. There is no way to emulate this conversion in the C++03 nullptr_t implementation. The test for this conversion has been moved to a new test and marked XFAIL with c++03.
