* Add include for 'test_macros.h' to all the tests that were missing them. ↵Marshall Clow2019-05-312-0/+4

* Support tests in freestandingJF Bastien2019-02-044-4/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Freestanding is *weird*. The standard allows it to differ in a bunch of odd manners from regular C++, and the committee would like to improve that situation. I'd like to make libc++ behave better with what freestanding should be, so that it can be a tool we use in improving the standard. To do that we need to try stuff out, both with "freestanding the language mode" and "freestanding the library subset". Let's start with the super basic: run the libc++ tests in freestanding, using clang as the compiler, and see what works. The easiest hack to do this: In utils/libcxx/test/config.py add: self.cxx.compile_flags += ['-ffreestanding'] Run the tests and they all fail. Why? Because in freestanding `main` isn't special. This "not special" property has two effects: main doesn't get mangled, and main isn't allowed to omit its `return` statement. The first means main gets mangled and the linker can't create a valid executable for us to test. The second means we spew out warnings (ew) and the compiler doesn't insert the `return` we omitted, and main just falls of the end and does whatever undefined behavior (if you're luck, ud2 leading to non-zero return code). Let's start my work with the basics. This patch changes all libc++ tests to declare `main` as `int main(int, char**` so it mangles consistently (enabling us to declare another `extern "C"` main for freestanding which calls the mangled one), and adds `return 0;` to all places where it was missing. This touches 6124 files, and I apologize. The former was done with The Magic Of Sed. The later was done with a (not quite correct but decent) clang tool: https://gist.github.com/jfbastien/793819ff360baa845483dde81170feed This works for most tests, though I did have to adjust a few places when e.g. the test runs with `-x c`, macros are used for main (such as for the filesystem tests), etc. Once this is in we can create a freestanding bot which will prevent further regressions. After that, we can start the real work of supporting C++ freestanding fairly well in libc++. <rdar://problem/47754795> Reviewers: ldionne, mclow.lists, EricWF Subscribers: christof, jkorous, dexonsmith, arphaman, miyuki, libcxx-commits Differential Revision: https://reviews.llvm.org/D57624 llvm-svn: 353086
* Update more file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-194-16/+12
| | | | | | | | | | | | | | | | | | to reflect the new license. These used slightly different spellings that defeated my regular expressions. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351648
* [libcxx] Make UNSUPPORTED for std::async test more fine grainedLouis Dionne2018-11-291-1/+8
| | | | | | | | The test was previously marked as unsupported on all Apple platforms, when we really just want to mark it as unsupported for previously shipped dylibs on macosx. llvm-svn: 347920
* [libcxx] Mark std::async race condition test as unsupported on DarwinLouis Dionne2018-10-091-0/+4
| | | | | | | | | | PR38682 added a test to check for a race condition in std::future. Part of the fix is part of the dylib, but there is no released version of mac OS X that ships a dylib containing the fix. Hence, this test can (and sometimes does) when testing on OS X. This commit marks the test as unsupported to avoid spurious failures. llvm-svn: 344053
* [libc++] Remove race condition in std::asyncLouis Dionne2018-08-241-0/+58
| | | | | | | | | | | | | | | | | Summary: The state associated to the future was set in one thread (with synchronization) but read in another thread without synchronization, which led to a data race. https://bugs.llvm.org/show_bug.cgi?id=38181 rdar://problem/42548261 Reviewers: mclow.lists, EricWF Subscribers: christof, dexonsmith, cfe-commits Differential Revision: https://reviews.llvm.org/D51170 llvm-svn: 340608

* [libcxx] Recover no-exceptions XFAILs - IAsiri Rathnayake2016-10-061-2/+3
| | | | | | | | | | | | | | | | First batch of changes to get some of these XFAILs working in the no-exceptions libc++ variant. Changed some XFAILs to UNSUPPORTED where the test is all about exception handling. In other cases, used the test macros TEST_THROW and TEST_HAS_NO_EXCEPTIONS to conditionally exclude those parts of the test that concerns exception handling behaviour.

* Fix or move various non-standard tests.Eric Fiselier2016-04-291-110/+63
| | | | | | | | | | | | This patch does the following: * Remove <__config> includes from some container tests. * Guards uses of std::launch::any in async tests because it's an extension. * Move "test/std/extensions" to "test/libcxx/extensions" * Moves various non-standard tests including those in "sequences/vector", "std/localization" and "utilities/meta". llvm-svn: 267981

* Make it possible to build a no-exceptions variant of libcxx.Asiri Rathnayake2015-11-101-0/+1
| | | | | | | | | | | | Fixes a small omission in libcxx that prevents libcxx being built when -DLIBCXX_ENABLE_EXCEPTIONS=0 is specified. This patch adds XFAILS to all those tests that are currently failing on the new -fno-exceptions library variant. Follow-up patches will update the tests (progressively) to cope with the new library variant. Change-Id: I4b801bd8d8e4fe7193df9e55f39f1f393a8ba81a llvm-svn: 252598
