* [libc++] Relax libc++-only test on regex_constantsLouis Dionne2019-04-261-13/+13
| | | | | | | | | | | | | | The standard requires the following for the std::regex_constants::error_type values: "The type error_type is an implementation-defined enumerated type." The values of this enumerated type are not required to be non-zero. This patch makes such checks in tests libc++-specific to let the tests pass for other conforming implementations.

* Support tests in freestandingJF Bastien2019-02-04177-177/+519
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Carruth2019-01-19176-704/+528
| | | | | | | | | | | | | | | | | | 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
* [NFC] Normalize some test 'main' signaturesJF Bastien2019-01-091-2/+1

* [libcxx] Remove XFAILs for older macOS versionsLouis Dionne2018-12-181-3/+0

* [test] Add target_info for NetBSD, and XFAIL some of locale testsMichal Gorny2018-12-1710-0/+30
| | | | | | | | | | | | | | | | | | | | Add a target_info definition for NetBSD. The definition is based on the one used by FreeBSD, with libcxxrt replaced by libc++abi, and using llvm-libunwind since we need to use its unwinder implementation to build anyway. Additionally, XFAIL the 30 tests that fail because of non-implemented locale features. According to the manual, NetBSD implements only LC_CTYPE part of locale handling. However, there is a locale database in the system and locale specifications are validated against it, so it makes sense to list the common locales as supported. If I'm counting correctly, this change enables additional 43 passing tests. Differential Revision: https://reviews.llvm.org/D55767 llvm-svn: 349379

* Adjust unsupported C++ versions in some testsMikhail Maltsev2018-10-242-2/+2
| | | | | | | | | | | | | | | | | | | | Summary: Some tests (mainly the new C++20 calendar library) fail when libc++ is tested with '--param=std=c++98'. The failures happen because the tests actually don't support C++98, but don't mention C++98 in the 'UNSUPPORTED:' line. This change fixes the issue.
