The output has been subject to swaps of the form

0 1 -> 3 1 but the odd and even bits have been put into

2 3 2 0

different words. The main trick is to remember that

t=((l>>size)^r)&(mask);
|

r^=t;
|

l^=(t<<size);
|

can be used to swap and move bits between words.

becomes (for size == 2 and mask == 0x3333)

t = 2^16 3^17 -- -- l = 0 1 16 17 r = 2 3 18 19

Thanks for hints from Richard Outerbridge - he told me IP&FP
|

could be done in 15 xor, 10 shifts and 5 ands.
|

When I finally started to think of the problem in 2D
|

I first got ~42 operations without xors. When I remembered
|
||||
how to use xors :-) I got it to its final state.
