I have some code that seems to be acting funny to me.
regardless of whether the symbol DOMAINHASH is defined or not, the
following fails to compile with the error
/Users/markian/Documents/School/PhD/Development/CodeGen/SearchEngine/
TT.cc:90: error: parse error before `return'
for(i=0;i<TT_SIZE;i++)
{
TransTable[i].depth=-1; //set all unused transposition entries
to have
//an invalid depth of -1
}
#ifndef DOMAINHASH
{
//if we're using the generic TT Hash
GetTTHash = Generic_GetTTHash;
GetZobristkey = Generic_GetZobristkey;
for(i=0;i<ZOBRIST_SIZE;i++)
for(j=0;j<ZOBRIST_DEPTH;j++)
{
bluff=(int*)(&(Zobrist[i][j]));
bluff[0]=random();
bluff[1]=random();
}//for j
#ifdef DEBUG_VERBOSE
printf("\nUsing generic Zobrist\n\n");
#endif
#elif defined(DOMAINHASH) & defined(DEBUG_VERBOSE)
printf("\nUsing domain-provided hash function\n\n");
//call hooks to initialize domain zobrist, etc. inside Board Init.
}
#endif
yet the following compiles fine. Note the different placement of the {}
around the outer #ifdef block.
Am I doing something wrong, or is there a bug in the parser here? And
is it a xcode bug, or a gcc bug?
for(i=0;i<TT_SIZE;i++)
{
TransTable[i].depth=-1; //set all unused transposition entries
to have
//an invalid depth of -1
}
{
#ifndef DOMAINHASH
//if we're using the generic TT Hash
GetTTHash = Generic_GetTTHash;
GetZobristkey = Generic_GetZobristkey;
for(i=0;i<ZOBRIST_SIZE;i++)
for(j=0;j<ZOBRIST_DEPTH;j++)
{
bluff=(int*)(&(Zobrist[i][j]));
bluff[0]=random();
bluff[1]=random();
}//for j
#ifdef DEBUG_VERBOSE
printf("\nUsing generic Zobrist\n\n");
#endif
#elif defined(DOMAINHASH) & defined(DEBUG_VERBOSE)
printf("\nUsing domain-provided hash function\n\n");
//call hooks to initialize domain zobrist, etc. inside Board Init.
#endif
}
Thanks!
