Hello,

Look at this scalable Asymmetric rw_mux from Dmitry Vyukov:

https://groups.google.com/forum/#!topic/lock-free/Hv3GUlccYTc


If you have noticed he is using a compiler "_ReadWriteBarrier()",
but this doesn't emmit a fence on x86, it is just a compiler barrier,
but i am wondering how can he do it this way because loads
of the reader critical section are reordered with the following store:

reader_inside[current_thread_index] = true;


So i think it is a bug, can you please share a light on this ?



Thank you,
Amine Moulay Ramdane.
