That would potentially be nice, but I don't know of any tools that would
allow us to symbolically debug a dump without having a separate source of
symbol information (like xen-syms). The problems you mention would typically
be resolved by non-technical means anyway (offical release builds for which
you keep a copy of the bits, which can then be used to augment the
information from a raw dump). I wouldn't deep-dive into a core dump for a
build of dubious heritage where the builder hadn't kept the sources and
build bits! :-)
