It's fine that you moved the 2nd case to 'tree-optimization'. I suppose that's
where it belongs.
But I just saw the second case by chance in the process of reduction of the
first case to bare minimum. For me it (the second case) is not really
important.
What I care about is the first case. 
Could you please mark it as 'target', so persons responsible for Nios2 back end
wouldn't overlook it?
