Thanks for taking care. I wanted to do myself very soon. Purpose why
I delayed it was the fact, that Joern complained about fixed registers.
To my opinion his example dealing with fixed registers is more problem in the
backend and should not be taken into care. In recent days I was really busy so
I didn't had time to settle down this problem and do that myself.
Thanks a lot!
