The temporary workaround I did last night was to make the sparc dwarf2
CIF unwinder init_reg() routine just mark G0 as UNDEFINED. I don't
know if that's what we'd like to do long term, or if GCC should output
something for this register.
Hmm, I think it is better to mark it as SAME_VALUE; %g0 will always be
%g0. No compiler will ever be able to change that ;-).
I'm going to get some sleep now. If you'll commit that tramp_frame
diff, I'm going to do some more work on this tomorrow ;-).
Mark
