   The parts that are NOT mentioned in the changelog (your changes
   to the logic in sparc_init_extra_frame_info) are not OK, first
   because you didn't mention them in the changelog, and second 
   because I can't convince myself that they are right.

Michael, I hate keeping on about this, but I did mention
them in my changes:

        (sparc_init_extra_frame_info): Use sparc_skip_prologue to find
        prologue bounds instead of looking at line number info by hand.

I know you're going to explode at me, but you seem to make a lot of
errors reviewing my changes.  Please settle down, take your time.  At
this point I'd much rather you delay than review things haphazardly.

Thank you.
