Obsd has a different ABI here, and nbsd too, we, fbsd lack the altivec regs in reg(s).h. My questions are in terms of signal handling and stack unwinding. How do we do that, what are the 'correct' entry points etc. I have to admit, I solved my thunderbird issue :) I could step into the functions, even assembler stuff. But the confusing part is the testsuite which makes me unsure and the fact that we do not store/giving access to altivec regs, Nathan? Thanks for the response, Andreas
