Essentially, it comprises my adjustments to `make_index` that remained unmerged before threat inputs was finalized. The unsigned intermediate variables let us skip a bunch of useless sign extensions (because Square and Piece inherit from `int8_t`, and C/C++ semantics require narrow integers to be promoted to `int` before doing arithmetic on them). Additionally, by removing the special usage of `offsets[][64]` and `[65]` the indexing becomes more efficient. (This usage was a temporary hack from sscg anyway, so I think he'll like that it's gone.) Finally, the `sf_assume` condition was fixed so that it actually makes a difference to the compiler. The speedup is fairly nice locally (combining both ces42's and these changes): ``` Result of 100 runs ================== base (...kfish.master) = 1691982 +/- 1907 test (./stockfish ) = 1714349 +/- 1789 diff = +22367 +/- 2465 speedup = +0.0132 P(speedup > 0) = 1.0000 ``` closes https://github.com/official-stockfish/Stockfish/pull/6445 No functional change see source |

Date: Mon Nov 17 13:24:32 2025 +0100 Timestamp: 1763382272 Use non-locking operations for nodes count and tbHits fetch_add and friends must produce a locking instruction because they guarantee consistency in the presence of multiple writers. Because only one thread ever writes to nodes and tbHits, we may use relaxed load and store to emit regular loads and stores (on both x86-64 and arm64), while avoiding undefined behavior and miscounting nodes. Credit must go to Arseniy Surkov of Reckless (codedeliveryservice) for uncovering this performance gotcha. failed yellow as a gainer on fishtest: LLR: -2.95 (-2.94,2.94) <0.00,2.00> Total: 219616 W: 57165 L: 57105 D: 105346 Elo +0.09 Ptnml(0-2): 732, 24277, 59720, 24357, 722 https://tests.stockfishchess.org/tests/view/69086abfea4b268f1fac2809 potential small speedup on large core system: ``` ==== master ==== 1 Nodes/second : 294269736 2 Nodes/second : 295217629 Average (over 2): 294743682 ==== patch ==== 1 Nodes/second : 299003603 2 Nodes/second : 298111320 Average (over 2): 298557461 ``` closes https://github.com/official-stockfish/Stockfish/pull/6392 No functional change see source |

The principal application for now is syzygy_extend_pv().
