I think the ISO C and C++ definition of memory_order_consume will need to be fixed first. Perhaps recent progress has been made, but see for example "C++ P0371R1: Temporarily discourage memory_order_consume" and references therein: http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2016/p0371r1.html http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2016/p037...
