Date: Thu Oct 31 10:08:34 2024 +0100 Timestamp: 1730365714 Remove moveCountPruning in search.cpp The definition of moveCountPruning may cause confusion by implying that the variable is unconstrained. However, once it is set to true, it should not be reset to false, otherwise it would break the internal logic of MovePicker. Several patches have overlooked this constraint.

This pr improves it a little bit for the help and config-sanity targets, with the latter also improving `make -j build` because it depends on that. On the same machine ubuntu (wsl) is more than 3 times faster, if there are other improvements we can make I'd be happy to hear about them. Ultimately https://github.com/official-stockfish/Stockfish/pull/5543 also aims to improve this I believe, but it will take some additional time before that lands. ``` make config-sanity: patch: 6.199s master: 12.738s make help: patch: 3.1s master: 11.49s make -j build: patch: 36s master: 43.25s make -j build: master ubuntu: 10s ``` closes https://github.com/official-stockfish/Stockfish/pull/5642 No functional change see source |
