4. Apple has not documented the memory sychronization properties of this API.
If you give me a specific question to ask of Apple, I will work on getting the answer.
"What are the memory synchronization properties of the atomic primitives?" is one good question, but "Is there a specific reason for not encouraging the developers to use lwarx/stwcx. except memory visibility issues on a multiprocessor?" is a much better one. FWIW, http://www.opensource.apple.com/darwinsource/10.3/gccfast-1614/libjava/sysde... uses lwarx/stwcx./sync/isync in a way that matches our understanding of how they are supposed to be used. There are other examples in Apple's own code, but opensource.apple.com wants me to register to see them. ;-)
