Could this transformation be still effective in modern processors?
- retrac 3y agoIt wouldn't be needed today on x86_64. The underlying idea - priming the processor with hints about what and when - is now standard practice. There are explicit instructions for manipulating the cache and marking data as needed-soon. E.g. PREFETCH, available as __builtin_prefetch in GCC. Added to the Pentium III, I think.
