Refactor tbprobe.cpp This involves: * replacing the union hacks with simply reusing the EntryPiece arrays for the no-pawns case * merging the PairsData structure with the EntryPiece/-Pawn structs (with credit to Marco: @mcostalba) * simplifying some HashTable functions * thanks to previous changes, removing the ugly memsets * simplifying the template logic for WDL/DTZ distinction (now we distinguish based on an enum type, not the entry classes) * removing the unneeded Atomic wrapper ----------------------------- For reference, here is a manual way to check that patches concerning table bases code are non-functional changes: 0) Download the Syzygy table bases (up to 6 men). 1) Make sure you have branches master and the pull request pointing to the right commits. 2) Download the bench calculation scripts from the following URL: https://gist.github.com/WOnder93/b5fcf9c989b4a1715684d5c82367cdbe and copy into src inside your Stockfish repo. 3) Make the scripts executable (chmod +x *.sh). 4) Run the following command to use TBs located at <path>: export SYZYGY_PATH='<path>' 5) After that, run this (it will take a long time, this is a deep bench): BENCH_ARGS='128 1 22' ./check_benches.sh master tbprobe_cleanup 2>/dev/null` ==> You should see two equal numbers printed. (Of course, now we have to trust that the script itself is correct :) ----------------------------- Closes https://github.com/official-stockfish/Stockfish/pull/1477 No functional change.
