I don't remember anyone answering your email. That's too bad, because
I think that any attempt at reducing the size of debugging info is
interesting.

Regarding timing, I don't think we have to wait for GCC. As far as I can
tell, this would add a functionality without disturbing the current
behavior, right? Or perhaps the problem is actual testing of your code?

Speaking of GCC, do you know the status of the enhancement?

Do you have an updated version of your patch. I've mostyl been hacking
the dwarf2 reader, so hopefully someone more veteran can review the
code eventually, but my comments will (hopefully!) be better than
nothing :).
