Well David, I think that this would be very important. Let's say your are building some kind of debugger (e.g. frysk) using libunwind. This raises a problem that in a x86_64 system you have several processes that are only x86, and your debugger would not be able to unwind this processes, so you would need to use to different compiled debuggers.
I'm raising this problem because I'm working now in powerpc32 support, and that's very important because in a ppc64 server several processes are ppc32, and this will not change for a while, because they are intentionally 32 bits, in some cases, ppc32 binaries can be faster than ppc64. So it would be very important to libunwind64 be able to debug both ppc32 and ppc64, not only libunwind-ppc32 debug ppc32. And ppc32 and ppc54 have different ABIs, but linux for ppc63 is able to deal with both. What do you all think of it?
