[gnugo-devel] gnugo-3.8 bug report

[David Binderman]

Hello there,

Gcc has recently been extended with the warning for xor
used as pow. So:

1.

mkpat.c:1939:51: warning: result of '2^2' is 0; did you mean '1 << 2' (4)? 
[-Wxor-used-as-pow]

Source code is

     int xor_att = (el[k].color == color ? ATT_O ^ ATT_O : ATT_O ^ ATT_X);

I assume you meant

     int xor_att = (el[k].color == color) ? (ATT_O ^ ATT_O) : (ATT_O ^ ATT_X);

2.

mkpat.c:2005:55: warning: result of '2^1' is 3; did you mean '1 << 1' (2)? 
[-Wxor-used-as-pow]

Duplicate.

Regards
