 PNaCl bitcode does not support volatile memory accesses. The
 ``volatile`` attribute on loads and stores is not supported. See the
 :doc:`pnacl-c-cpp-language-support` for more details.

 The ``llvm.nacl.atomic.is.lock.free`` intrinsic is designed to
 determine at translation time whether atomic operations of a certain
 ``byte_size`` (a compile-time constant), at a particular ``address``,
 are lock-free or not. This reflects the C11 ``atomic_is_lock_free``
 function from header ``<stdatomic.h>`` and the C++11 ``is_lock_free``
 member function in header ``<atomic>``. It can be used through the
 ``__nacl_atomic_is_lock_free`` builtin.
