I'd love to help get it into mainline, but my knowledge of gdb internals
is rather poor currently. I figure I can help perhaps with coordination
and certainly with testing.
Jan, would getting PIE support into mainline gdb be something you would
have time for?

This is probably where I'd get hung up, shouting "it's magic!" :)

Yeah, I assume that I'll end up learning gdb internals eventually, and be
a bit more helpful then, but that won't be in the near-term. That said,
it's been 5 years since Elena Zannoni's original work, so I'm hoping
some folks will step up and help review the existing patches with me --
they clearly have some merit.
Thanks!
