* [libc++] Add proper XFAILs for shared_mutex testsLouis Dionne2019-03-2714-2/+13
| | | | | | | | | | Dylib support for shared_mutex was added in macOS 10.12, so the tests should be XFAILed accordingly instead of being completely disabled whenever availability is enabled. rdar://problem/48769104 llvm-svn: 357079
* Support tests in freestandingJF Bastien2019-02-0423-23/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Carruth2019-01-1923-92/+69
| | | | | | | | | | | | | | | | | | 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

* Add markup for libc++ dylib availabilityMehdi Amini2017-05-041-0/+2
| | | | | | | | | | | | | | | Libc++ is used as a system library on macOS and iOS (amongst others). In order for users to be able to compile a binary that is intended to be deployed to an older version of the platform, clang provides the availability attribute <https://clang.llvm.org/docs/AttributeReference.html#availability>_ that can be placed on declarations to describe the lifecycle of a symbol in the library. See docs/DesignDocs/AvailabilityMarkup.rst for more information. Differential Revision: https://reviews.llvm.org/D31739 llvm-svn: 302172

* Adjust libc++ test infastructure to fully support modulesEric Fiselier2016-12-053-3/+3
| | | | | | | | | | | | This patch overhalls the libc++ test format/configuration in order to fully support modules. By "fully support" I mean get almost all of the tests passing. The main hurdle for doing this is handling tests that `#define _LIBCPP_FOO` macros to test a different configuration. This patch deals with these tests in the following ways: 1. For tests that define single `_LIBCPP_ABI_FOO` macros have been annotated with `// MODULES_DEFINES: _LIBCPP_ABI_FOO`. This allows the test suite to define the macro on the command line so it uses a different set of modules. 2. Tests for libc++'s debug mode (which define custom `_LIBCPP_ASSERT`) are automatically detected by the test suite and are compiled and run with modules disabled. This patch also cleans up how the `CXXCompiler` helper class handles enabling/disabling language features. NOTE: This patch uses `LIT` features which were only committed to LLVM today. If this patch breaks running the libc++ tests you probably need to update LLVM. llvm-svn: 288728

* Add "FLAKY_TEST" test directive to support re-running flaky tests.Eric Fiselier2016-08-303-0/+6
| | | | | | | | Some of the mutex tests fail on machines with high load. This patch implements the test directive "// FLAKY_TEST" which allows a test to be run 3 times before it's considered a failure. llvm-svn: 280050
* [libcxx] Improve tests to use the UNSUPPORTED lit directiveAsiri Rathnayake2016-05-282-14/+2
| | | | | | | | | | | | | | | | | | | Quite a few libcxx tests seem to follow the format: #if _LIBCPP_STD_VER > X // Do test. #else // Empty test. #endif We should instead use the UNSUPPORTED lit directive to exclude the test on earlier C++ standards. This gives us a more accurate number of test passes for those standards and avoids unnecessary conflicts with other lit directives on the same tests.

* Make it possible to build a no-exceptions variant of libcxx.Asiri Rathnayake2015-11-105-0/+5
| | | | | | | | | | | | 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
