Ha, I did not see your post before making mine. You are correct in your assessment of the blame.

Moreover, I view optimization as an anti-pattern in general, especially for a low level language. It is better to directly write the optimal solution and not be dependent on the compiler. If there is a real hotspot that you have identified through profiling and you don't know how to optimize it, then you can run the hotspot through an optimizing compiler and copy what it does.
