* [libc++] Add test and remove workaround for PR13592Louis Dionne2019-10-301-3/+9
| | | | | | | | PR13592 was caused by a problem in how to compiler implemented the __is_convertible_to intrinsic. That problem, reported as PR13591, was fixed back in 2012. We don't support such old versions of Clang anyway, so we don't need the library workaround that had been added to solve PR13592 (while waiting for the compiler fix).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Carruth2019-01-191-4/+3
| | | | | | | | | | | | | | | | | | 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
* Cleanup test issues reported by STL @ Microsoft.Eric Fiselier2017-05-121-1/+3
| | | | | | | | | | | This patch cleans up a number of issues reported by STL, including: 1) Fix duplicate is_convertible test. 2) Move non-standard reference_wrapper tests under test/libcxx 3) Fix assumption that sizeof(wchar_t) == 32 in the codecvt and wstring_convert tests. llvm-svn: 302870

| | | | | | | | | | | | | types. This patch fixes a bunch of bugs in the fallback implementation of is_convertible, which is used by GCC. Removing the "__is_convertible" specializations for array/function types we fallback on the SFINAE test, which is more correct. See https://llvm.org/bugs/show_bug.cgi?id=27538 llvm-svn: 268359

| | | | | | | | | | | | | | | | | | | of is_convertible. Summary: Currently the conversion check does not take place in a context where access control SFINAE is applied. This patch changes the context of the test expression so that SFINAE occurs if access control does not permit the conversion.
