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. For example: https://tests.stockfishchess.org/tests/view/671e7c0486d5ee47d953d226 https://tests.stockfishchess.org/tests/view/66a1de7b4ff211be9d4eccea The implementation approach was suggested by Disservin.

Date: Thu Oct 31 09:25:59 2024 +0100 Timestamp: 1730363159 Speedup Makefile on Windows The Makefile is notoriously slow on windows, because of new processes being spawned I believe. 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 |
