Marshall Clow	aafb3151a8	Add tests to make sure that <string_view> provides std::size/data/empty in C++17 mode. This is LWG#3009, coming up for a vote in JAX - but we already do it, just don't have tests llvm-svn: 323719	2018-01-30 00:47:43 +00:00
Marshall Clow	25a7ba4524	More of P0600 - '[[nodiscard]] in the Library' mark empty() as nodiscard in string, string_view, and the free function std::empty(). Removed tabs from <string_view>, which is why the diff is so big. llvm-svn: 318328	2017-11-15 20:02:27 +00:00
Stephan T. Lavavej	0f901c7ec4	[libcxx] [test] Replace _LIBCPP_STD_VER with TEST_STD_VER. This replaces every occurrence of _LIBCPP_STD_VER in the tests with TEST_STD_VER. Additionally, for every affected file, #include "test_macros.h" is being added explicitly if it wasn't already there. https://reviews.llvm.org/D26294 llvm-svn: 286007	2016-11-04 20:26:59 +00:00
