The roland/unwind branch has readelf changes for CFI printing
that I did ages ago. I think mine made use of some new libdw
functions not merged yet, is why I never merged that.
It's worth comparing that branch's readelf changes with what
you've done to see if I did anything better. (I don't really
remember any particular details now.)
Was there anything in particular that spurred you to hack on this?
(Like working on some CFI new hackery?) Please post and/or wikiize
about anything you are working on, just so everybody knows what's afoot.
Thanks,
Roland
