test/support/msvc_stdlib_force_include.hpp When testing MSVC's STL with C1XX, simulate a couple more compiler feature-test macros. When testing MSVC's STL, simulate a few library feature-test macros. test/std/atomics/atomics.lockfree/isalwayslockfree.pass.cpp The vector_size attribute is a non-Standard extension that's supported by Clang and GCC, but not C1XX. Therefore, guard this with `__has_attribute(vector_size)`. Additionally, while these tests pass when MSVC's STL is compiled with Clang, I don't consider this to be a supported scenario for our library, so also guard this with defined(_LIBCPP_VERSION). test/std/utilities/function.objects/func.not_fn/not_fn.pass.cpp N4713 23.14.10 [func.not_fn]/1 depicts only `call_wrapper(call_wrapper&&) = default;` and `call_wrapper(const call_wrapper&) = default;`. According to 15.8.2 [class.copy.assign]/2 and /4, this makes call_wrapper non-assignable. Therefore, guard the assignability tests as libc++ specific. Add a (void) cast to tolerate not_fn() being marked as nodiscard. Fixes D41213. git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@322144 91177308-0d34-0410-b5e6-96231b3b80d8
