Why is it surprising that atomic can be optimized?

• Sharlin 5y ago
  Writing correct, even if non-optimal, code that uses atomics is already highly non-trivial. Transforming code that uses atomics into more efficient forms while guaranteeing the same behavior is even more non-trivial.

    But is difficult for the programmer not more difficult for the compiler, isn't it?
