* [libc++] Purge mentions of GCC 4 from the test suiteLouis Dionne2019-09-251-1/+1
| | | | | | | | | We don't support GCC 4 and older according to the documentation, so we should pretend it doesn't exist. This is a re-application of r372787. llvm-svn: 372916
* Revert r372777: [libc++] Implement LWG 2510 and its follow-upsIlya Biryukov2019-09-251-1/+1
| | | | | | | | | | | | This also reverts: - r372778: [libc++] Implement LWG 3158 - r372782: [libc++] Try fixing tests that fail on GCC 5 and older - r372787: Purge mentions of GCC 4 from the test suite Reason: the change breaks compilation of LLVM with libc++, for details see http://lists.llvm.org/pipermail/libcxx-dev/2019-September/000599.html llvm-svn: 372832

* Support tests in freestandingJF Bastien2019-02-0417-17/+51
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Carruth2019-01-1917-68/+51
| | | | | | | | | | | | | | | | | | 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

* Provide a constexpr addressof with GCC 7.Eric Fiselier2016-10-101-1/+1
| | | | | | | | | | | | | | | | __builtin_addressof was added to the GCC trunk in the past week. This patch teaches libc++ about it so it can correctly provide constexpr addressof. Unfortunately this patch will break users of earlier GCC 7 builds, since we expect __builtin_addressof but one won't be provided. One option would be to only use __builtin_addressof for GCC 7.1 and above, but that means waiting for another release. Instead I've specifically chosen to break older GCC 7 versions. Since GCC 7 has yet to be released, and the 7.0 release is a development release, I believe that anybody currently using GCC 7.0 will have no issue upgrading. llvm-svn: 283715

* Make it possible to build a no-exceptions variant of libcxx.Asiri Rathnayake2015-11-104-0/+4
| | | | | | | | | | | | 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
