Hi Dalibor,
I have managed to solve this on my own by using conditional compilation to make sure that %EBP is not part of most reg_classes used for register allocation on VOS. I'm on to other problems.
Thanks for the tip, though.
Richard

Hi Richard,
I believe that this question is best suited for the hotspot-dev mailing list.
