* [libcxx] [test] Update locale names for Windows.Stephan T. Lavavej2017-06-083-15/+15
| | | | | | | | | | | | | | | | | locale.codecvt.byname/ctor_char.pass.cpp: This test used to use "en_US" as a plain string instead of using platform_support. Need to fix this because MS STL expects "en-US" instead. platform_support.h: These are the legacy Windows locale names. Should use IETF tags instead. I've also added en_US, since a test was using that as a locale string as well. msvc_stdlib_force_include.hpp: Remove _MSVC_STL_VER. The libraries will directly define _MSVC_STL_VERSION in the future. Fixes D29351. llvm-svn: 305000

| | | | | | | | Richard decided to fix these cases in Clang, even though they are representative of a larger problem for more complex cases. llvm-svn: 304966
* Fix class template deduction for scoped_lock.Eric Fiselier2017-06-081-1/+5
| | | | | | | | | r304862 changed how CTD handles deducing a non-primary class template using a non-dependent constructor of the primary template. This change requires libc++ to provide explicit deduction guides to make scoped_lock work again. llvm-svn: 304955
* Fix compile error with Bionic's PTHREAD_MUTEX_INITIALIZEREric Fiselier2017-06-072-1/+6
| | | | | | | | | | | | | | | | | | | | | | On Bionic PTHREAD_MUTEX_INITIALIZER contains the expression "<enum-type> & <integer-type>", which causes ADL to perform name lookup for operator&. During this lookup Clang decides that it requires the default member initializer for std::mutex while defining the DMI for std::mutex::__m_. If I'm not mistaken this is caused by the explicit noexcept declaration on the defaulted constructor. This patch removes the explicit noexcept and instead allows the compiler to declare the default constructor implicitly noexcept. It also adds a static_assert to ensure that happens. Unfortunatly because it's not easy to change the value of _LIBCPP_MUTEX_INITIALIZER for a single test there is no good way to test this patch. The Clang behavior causing the trouble here was introduced in r287713, which first appears in the 4.0 release. llvm-svn: 304942

* Implement LWG 2904.Michael Park2017-06-074-76/+8
| | | | | | | | | | | | | | | | | | | Summary: - Removed the move-constructibe requirement from copy-assignable. - Updated `__assign_alt` such that we direct initialize if `_Tp` can be `nothrow`-constructible from `_Arg`, or `_Tp`'s move construction can throw. Otherwise, construct a temporary and move it. - Updated the tests to remove the pre-LWG2904 path. Depends on D32671.

| | | | | | | | | | | | | | | | Summary: This patch improves how libc++ handles min/max macros within the headers. Previously libc++ would undef them and emit a warning. This patch changes libc++ to use `#pragma push_macro` to save the macro before undefining it, and `#pragma pop_macro` to restore the macros and the end of the header.

| | | | | | | | | | | | | This patch adds end-to-end/breathing tests for coroutines into libc++. The tests aren't specifically to test libc++ requirements but instead are intented to ensure coroutines are working fine in general. Although libc++ isn't exactly the most correct place for these tests to live, there is one major advantage. The libc++ test suite is also used by MSVC and by adding the tests here it ensures they will be run against all currently available coroutine implementations. llvm-svn: 304101
