Hi Sjoerd,

Hopefully the changes address the two problems that you found. I still need to write a couple of other tests to convince myself there isn't still an issue similar the one you reported with the aborted compilation.

Most of the changes are code movement, the functional changes are that I now handle negative immediates in all cases, not just the special cased icmp. The mutation of 'roots' has also been tweaked to fix the other issue.

cheers,
