[libcxx-commits] [PATCH] D75243: [libc++] Build the dylib with C++17 to allow aligned new/delete

[dmajor via Phabricator via libcxx-commits]

dmajor added a comment.

In our builds with the 10.12 SDK and MACOSX_DEPLOYMENT_TARGET of 10.11, this is producing

  [task 2020-07-22T21:52:27.615Z] /builds/worker/fetches/llvm-project/llvm/projects/libcxx/src/barrier.cpp:37:43: error: aligned allocation function of type 'void *(std::size_t, std::align_val_t)' is only available on macOS 10.14 or newer
  [task 2020-07-22T21:52:27.615Z]         __state = unique_ptr<__state_t[]>(new __state_t[__count]);
  [task 2020-07-22T21:52:27.615Z]                                           ^
  [task 2020-07-22T21:52:27.615Z] /builds/worker/fetches/llvm-project/llvm/projects/libcxx/src/barrier.cpp:37:43: note: if you supply your own aligned allocation functions, use -faligned-allocation to silence this diagnostic

Is that expected? How can I determine whether our builds supplies its own aligned allocation functions?
