Not a real functional change, but bench changed due to different piecelist
reordering. To verify it a temporary my canonicalize_rooks function was
written as follows. It just ensures that the rook on the "smaller" square
is listed first.
void Position::canonicalize_rooks(Color c)
{
if (pieceCount[c][ROOK] == 2)
{
Square s0 = pieceList[c][ROOK][0];
Square s1 = pieceList[c][ROOK][1];
if (s0 > s1)
{
pieceList[c][ROOK][0] = s1;
pieceList[c][ROOK][1] = s0;
index[s0] = 1;
index[s1] = 0;
}
}
}
With this both bench and the test on Chess960 positions
./stockfish bench 128 1 8 Chess960.epd file > /dev/null
Gives same result.
bench: 4424151
