* Support tests in freestandingJF Bastien2019-02-0466-66/+198
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Carruth2019-01-1966-264/+198
| | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | | | | perform push_back instead of emplace_back. Summary: The constructors `vector(Iter, Iter, Alloc = Alloc{})` and `assign(Iter, Iter)` don't correctly perform EmplaceConstruction from the result of dereferencing the iterator. This results in them performing an additional and unneeded copy. This patch addresses the issue by correctly using `emplace_back` in C++11 and newer. There are also some bugs in our `insert` implementation, but those will be handled separately. @mclow.lists We should probably merge this into 5.1, agreed?

* [libc++] Fix stack_allocatorEric Fiselier2016-10-084-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: To quote STL the problems with stack allocator are" >"stack_allocator<T, N> is seriously nonconformant to N4582 17.6.3.5 [allocator.requirements]. > First, it lacks a rebinding constructor. (The nested "struct rebind" isn't sufficient.) > Second, it lacks templated equality/inequality. > Third, it completely ignores alignment. > Finally, and most severely, the Standard forbids its existence. Allocators are forbidden from returning memory "inside themselves". This requirement is implied by the Standard's requirements for rebinding and equality. It's permitted to return memory from a separate buffer object on the stack, though." This patch attempts to address all of those issues. First, instead of storing the buffer inside the allocator I've change `stack_allocator` to accept the buffer as an argument. Second, in order to fix rebinding I changed the parameter list from `<class T, size_t NumElements>` to `<class T, size_t NumBytes>`. This allows allocator rebinding between types that have different sizes. Third, I added copy and rebinding constructors and assignment operators. And finally I fixed the allocation logic to always return properly aligned storage.

* [libc++] Remove various C++03 feature test macrosEric Fiselier2016-09-251-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | Summary: Libc++ still uses per-feature configuration macros when configuring for C++11. However libc++ requires a feature-complete C++11 compiler so there is no reason to check individual features. This patch starts the process of removing the feature specific macros and replacing their usage with `_LIBCPP_CXX03_LANG`. This patch removes the __config macros: * _LIBCPP_HAS_NO_TRAILING_RETURN * _LIBCPP_HAS_NO_TEMPLATE_ALIASES * _LIBCPP_HAS_NO_ADVANCED_SFINAE * _LIBCPP_HAS_NO_DEFAULT_FUNCTION_TEMPLATE_ARGS * _LIBCPP_HAS_NO_STATIC_ASSERT As a drive I also changed our C++03 static_assert to use _Static_assert if available.
