N.B. libstdc++ had a compare_and_swap primitive until a couple of years ago, when it was removed because nothing was using it and it was a headache when porting libstdc++ to new architectures. I'm going to ask about the possibility of resurrecting that compare_and_swap(),
Do the right thing and tell'em to introduce atomic<> with IBM style CAS (with msync decorators of course) and etceteras as lowest common denominator (RIP i386). Arch specific stuff (like load_reserved() and store_conditional() member functions) shall be available too (less portability... but global warming matters, they say ;-) ). regards, alexander.
