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:

Maybe the best thing to do is to write a really, really, really good test suite for the C11 compiler first.

I think u can propose it for C22

From June 15, 2016. They reference GCC 7.1 as being a year away...

  GCC 7.1

Pretty close.

Is this a thing now?

Downvotes? I merely meant to ask if linux implemented C11 atomics or not...
