@pitrou thank you for the review. Comments inline. > Ok, I find the implementation quite convoluted. I would like to see the following changes: > > * Make all critical functions inline If this is AdvanceTillWord, this hurts performance. LoadInitialWord in the constructor can be done but I don't think it will have a large impact on performance. > * Load a single byte at a time (it probably doesn't bring much to process an entire 64-bit word at a time, and it adds complication) I'm not sure I understand what direction you would like me to take here. I would expect word level handling to be much faster for cases this is intended for (when there are actual runs). In practice, once integrated into a system you are likely correct though. But I'm not sure exactly what algorithm you are thinking of for byte level handling. If you provide more description I can try to implement it and compare. > * Try to simplify mask handling Is this mostly InvertRemainingBits? could you provide some more feedback on the algorithm structure you were thinking of? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
