Detailed Description

This module deals with flipping discs.

A function is provided for each square of the board. These functions are gathered into an array of functions, so that a fast access to each function is allowed. The generic form of the function take as input the player and the opponent bitboards and return the flipped squares into a bitboard.

Given the following notation:

x = square where we play,
P = player's disc pattern,
O = opponent's disc pattern, the basic principle is to read into an array the result of a move. Doing this is easier for a single line ; so we can use arrays of the form:
ARRAY[x][8-bits disc pattern]. The problem is thus to convert any line of a 64-bits disc pattern into an 8-bits disc pattern. A fast way to do this is to select the right line, with a bit-mask, to gather the masked-bits into a continuous set by a simple multiplication and to right-shift the result to scale it into a number between 0 and 255. Once we get our 8-bits disc patterns,a first array (OUTFLANK) is used to get the player's discs that surround the opponent discs:
outflank = OUTFLANK[x][O] & P (Only inner 6-bits of the P are in interest here.) The result is then used as an index to access a second array giving the flipped discs according to the surrounding player's discs:
flipped = FLIPPED[x][outflank]. (Flipped discs fall into inner 6-bits.) Finally, a precomputed array transform the inner 6-bits disc pattern back into a 64-bits disc pattern, and the flipped squares for each line are gathered and returned to generate moves.

If the OUTFLANK search is in LSB to MSB direction, carry propagation can be used to determine contiguous opponent discs. If the OUTFLANK search is in MSB to LSB direction, GCC's __builtin_clz(ll) is used to determine coutiguous opponent discs.
