Re: RFA: ia64 portion of libunwind patch


Because it may not have the elf binary (at least not locally), and it
may not have debug info. People still expect GDB to do something reasonable in those cases.


I'm a little bit puzzled about why we wouldn't have the elf binary...

But, assuming for the moment that we do, we'll definitely have the
unwind info since it's mandated by the ABI.

"at least not locally". The unwind info can always be found in the target's memory.


There are two choices here:
- make the interface more remote friendly
- just ignore the issue until someone complains

Hmm, a good question to ask is "how cross debug friendly" is libunwind.? If its anything like libthread-db then this discussion is mute.
