SWAP
Obviously better written something like:
int times = (loop +7) >> 3; // number of loops, rounded up
unsigned offset = loop & 7; // remainder div 8
switch(offset) {
case 0: do { SWAP;
case 7: SWAP;
case 6: SWAP;
case 5: SWAP;
case 4: SWAP;
case 3: SWAP;
case 2: SWAP;
case 1: SWAP;
} while (--times > 0);
}
Much clearer, surely :)
