Hi all,
As a data point, we are using a snapshot of libunwind from July,
2011 in our OpenSpeedShop performance tool for the Columbia IA64
platform at NASA and it works well for our purposes. I have not
tried the 1.0.1 release, there, but we are in the process of testing
how version 1.0.1 works in our tool.
Thanks
Jim G.

Volker,
I don't think anybody every seriously pursued libunwind on
HP-UX since HP-UX already had a processor-specific unwind API.
I just did some basic work to verify that libunwind could work
in principle on HP-UX. It's a fair amount of work to properly
validate an unwind library on IA-64, so if you can live with a
processor-specific API, you might be better off with Unwind or
Unwind Express.
Having said that, the IA-64 tests in libunwind are quite
extensive and if you could "make check" to pass (mostly) you'd
probably be in good shape.
I haven't worked on IA-64 in several years, but I still have
an Itanium box, so I might be able to at least help make sure
the current libunwind works properly on IA-64 Linux.
