Another example to explain my concern. In the Linux kernel, list macros used to prefetch next items: “(...) So the conclusion is: prefetches are absolutely toxic, even if the NULL ones are excluded.”

The lesson is that we should not let developers tune the compiler: let the CPU do that for you :-) For example, CPUs have evolved heuristics to prefetch data for you.
