Thanks for looking into this. It seems only gdb is working on
integrating this feature ATM. I'll want to wait and see how the
discussion unfolds there before adopting it for elfutils:
http://thread.gmane.org/gmane.comp.gdb.patches/80846
It looks like they are also writing a technical specification for the
feature, which would be very welcome, since at the moment I have to
guess at some of it (why are some of the ELF notes in the compressed ELF
for example, are you supposed to cross-check they match?)

Thanks,

Mark
