Re: [Libunwind-devel] In the Linaro environment ...

[Myke Smith]

Ken,
Thanks, I am on vacation at the moment, I will work on this when I return..

I do not explicitly call out -funwind-tables but when I run you variant of 
debuggerd I do get everything to correctly backtrace even with stripped 
binaries which implies to me that the unwind-tables were being generated.

Thanks for your work on this and I will dig back in on my return.
