A further look at the gcc __sync_bool_compare_and_swap.

Continuing the looks-pretty-good gcc atomic CAS functions, the point would be how to move these great results in application and make the pretty testing result helps. For the purpose to understand clearly its behavior, some more tests have been done.

A rough survey on gcc builtin atomic operations.

When my colleague suggested me the gcc __sync_* functions, not much interest to me for which was treated as a low-level lock rather than a lock-free pattern. But it does surprise me after some survey.
