| 169 | The output has been subject to swaps of the form | ||
| 170 | 0 1 -> 3 1 but the odd and even bits have been put into | ||
| 171 | 2 3 2 0 | ||
| 172 | different words. The main trick is to remember that | ||
| 173 | t=((l>>size)^r)&(mask); | ||
| 174 | r^=t; | ||
| 175 | l^=(t<<size); | ||
| 176 | can be used to swap and move bits between words. | ||

| 188 | Thanks for hints from Richard Outerbridge - he told me IP&FP | ||
| 189 | could be done in 15 xor, 10 shifts and 5 ands. | ||
| 190 | When I finally started to think of the problem in 2D | ||
| 191 | I first got ~42 operations without xors. When I remembered | ||
| 192 | how to use xors :-) I got it to its final state. | ||
