hi folks, I wonder if it is the team Stockfish or if it is the compiler Jim Ablet, who are in trouble? ... because I think they don't like much of AMD processors ..., no version of the update or release 2.2.2, sse42 works in AMD processors, incredible not? I know that you can fix this, because not everyone we have intel processors, a big hug.

You need to buy an Intel processor. lol

1/0 games + perfect2012a ctg

Stockfish Stocks11

I will repeat what I said about this particular version: Please keep working on it. :)

* I have 4 notes about this compile (2012-05-27 and also 2012-05-28):

1- it chooses interesting lines;
2- it finds interesting moves to checkmates;
3- it never gives up;
4- go deeper reaching Depth=30 sometimes.

Congrats to the Team.

Marco Costalba wrote:

- Fix a compile error in opposite_colors()

Error is due to ambiguous overloading of operator^
because we have both the built-in operator^(int, int)
and the user defined operator^(Bitboard, Square).

This error does not trigger when using Makefile becuase,
due to luck, the user defined operator^(Bitboard, Square)
happens to be always defined _after_ opposite_colors() so
that compiler does not claim. But in case of Microsoft MSVC
we don't have a Makefile and the order of files compilation
is chosen by the compiler (in an unpredictable way). So it
could still happen that error is not detected (as in my case),
but in another case the order of compilation of the files could
be so that at some point both operator^ were defined before
opposite_colors() and this triggers the error.

The fix is much simpler than the explanation :-)

Reported by Quocvuong82.

No functional change.
