I'm pleased to announce a new release of my UCI engine : Orion 0.2

This version includes notably an attempt to automatically detect and use 'popcnt' instruction if present on your CPU. In case of problem, this can be disabled by running "Orion.exe -no-popcnt".

Yes, I saw : thank you a lot Leto (and all the CEGT team) for all these games ! I hope the new version will behave correctly with the popcnt detection : please let me know if you encounter problems (or not !)...

Unfortunately I couldn't test it, it's crashing when the engine has to make its move. It loads up and as soon as it has to make its first move it crashes.

Yes, Graham (from CCRL) has a similar problem on a PC without popcnt instruction : I apologize and I'm very confused...

I fixed the problem and I am currently playing non regression tests. The patched version should be available tomorrow morning.

Does your CPU support popcnt instruction (maybe there is another problem, according to the Murphy's law ) ?

Thanks,

David
