Remove precomputed SquareBB Bit-shifting is a single instruction, and should be faster than an array lookup on supported architectures. Besides (ever so slightly) speeding up the conversion of a square into a bitboard, we may see minor general performance improvements due to preserving more of the CPU's existing cache. passed STC: LLR: 2.95 (-2.94,2.94) <-1.75,0.25> Total: 47280 W: 12469 L: 12271 D: 22540 Ptnml(0-2): 128, 4893, 13402, 5087, 130 https://tests.stockfishchess.org/tests/view/63c5cfe618c20f4929c5fe46 Small speedup locally: ``` Result of 20 runs ================== base (./stockfish.master ) = 1752135 +/- 10943 test (./stockfish.patch ) = 1763939 +/- 10818 diff = +11804 +/- 4731 speedup = +0.0067 P(speedup > 0) = 1.0000 CPU: 16 x AMD Ryzen 9 3950X 16-Core Processor ``` Closes https://github.com/official-stockfish/Stockfish/pull/4343 Bench: 4106793
