Thanx for you detailed answer. I got kaffe to build now. But still it crashes.
One needs very detailed information about netbsd/hpcarm  kernel. Is there some 
more information about it anywhere. I did take a look but wasnt able to find 
it somewhere- eg. calling conventions(maybe its more gcc specific) and how 
registers are used.

And btw. does anybody have a complete list of SA1110 instructions?

Regards
And thanx in advance.
