atomic fence questions

[jinz2014]

I am not clear about atomic fence functions. Can you please advise the availability of atomic_fence_order_capabilities and atomic_fence_scope_capabilities in your library ? I think it is good to add them in SYCL. Thanks.

Reference
intel/llvm#8938

The libcudacxx library implements the ISO C++ Standard definition of the <atomic> header in <cuda/std/atomic> including std::atomic_thread_fence.

We also implement standards conforming extensions in the <cuda/atomic> header with types like cuda::atomic that add cuda::thread_scopes.

atomic_fence_order_capabilities and atomic_fence_scope_capabilities are not part of the ISO C++ Standard nor are they included in our extensions.
