Go up one level in this thread
one possible improvement :-) I would guess this reduces dependencies and may shlightly or microscopic faster: bitboard WhitePawnAttacks (bitboard b) { bitboard c = b; b ^= b; // b ^= c has to wait for the previous instruction b |= (c << 7) & 0x7F7F7F7F7F7F7F7F; b |= (c << 9) & 0xFEFEFEFEFEFEFEFE; return b; } Gerd
