* [libc++] Mark several tests as XFAIL on macosx10.7Louis Dionne2019-02-2731-0/+155
| | | | | | | | | | | | | | | Those tests fail when linking against a new dylib but running against macosx10.7. I believe this is caused by a duplicate definition of the RTTI for exception classes in libc++.dylib and libc++abi.dylib, but this matter still needs some investigation. This issue was not caught previously because all the tests always linked against the same dylib used for running (because LIT made it impossible to do otherwise before r349171). rdar://problem/46809586 llvm-svn: 354940
* Support tests in freestandingJF Bastien2019-02-04225-238/+688
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Carruth2019-01-19227-908/+681
| | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | | | | | iter_alloc_deduction.fail.cpp. After two failed attempts last week to make this work I am going back to a known good method of making this test pass on macOS...adding the current apple-clang version to the UNSUPPORTED list. During a previous patch review (https://reviews.llvm.org/D44103) it was suggested to just XFAIL libcpp-no-deduction-guides as was done to iter_alloc_deduction.pass.cpp. However this caused a an unexpected pass on: http://lab.llvm.org:8011/builders/libcxx-libcxxabi-x86_64-linux-ubuntu-gcc-tot-latest-std/builds/214 I then attempted to just mark libcpp-no-deduction-guides as UNSUPPORTED, however this caused an additional bot failure. So I reverted everything (https://reviews.llvm.org/rCXX327191). To solve this and get work unblocked I am adding apple-clang-9 to the original UNSUPPORTED list. llvm-svn: 327304

| | | | | | | | | | | | | In T_size_size.pass, there is an explicit template argument to std::min to ask for unsigned, to avoid type deduction errors. However, C1XX' warnings still hate this use, because a 64 bit value (a size_t) is being passed to a function accepting an unsigned (a 32 bit value). Instead, change the tests to pass around std::size_t instances, and explicitly narrow when constructing the string type under test. This also allows removal of explicit template arguments to std::min. llvm-svn: 302473

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | parameter types. Summary: This patch fixes http://llvm.org/PR31938. The description below is copy/pasted from the bug: The standard says: template<class charT, class traits = char_traits<charT>, class Allocator = allocator<charT>> class basic_string { using value_type = typename traits::char_type; // ... basic_string(const charT* s, const Allocator& a = Allocator()); }; libc++ actually chooses to declare the constructor as basic_string(const value_type* s, const Allocator& a = Allocator()); The implicit deduction guides from class template argument deduction make what was previously an implementation detail visible: std::basic_string s = "foo"; // error, can't deduce charT. The constructor in question is in the libc++ DSO, but fortunately it looks like fixing this will not result in an ABI break. @rsmith How does this look? I did more than just the constructors mentioned in the PR, but IDK how far to take it.
