False.
Compilers do optimize atomics, memory accesses around atomics, and utilize architecture-specific knowledge. My hobby is to encourage compilers to do more of this, programmers to rely on it, and hardware vendors to give us new atomic toys to optimize with. Oh, and standardize yet more close-to-the-metal concurrency and parallelism tools.
But, you say, surely volatile always means volatile, there’s nothing wrong with my benign races, nothing could even go wrong with non-temporal accesses, and who needs 6 memory orderings anyways‽ I’m glad you asked, let me tell you about my hobby…
