Hi,
I would like to use Dyninst for cross-platform binary analysis, e.g.,
analyzing PowerPC code on a x86 machine. Is this currently supported and
if so, how? From my experiments so far it seems like binaries for a
different CPU architectures are not recognized automatically and thus
cannot be decoded.
Thanks and best regards,
Stefan

The support for this is limited, but if you're looking for binary
analysis and not instrumentation, it shouldn't be too hard to get it
working. I believe, as a first approximation, that if you build the
analysis components (symtab, instructionapi, parseapi, dataflowapi) with
your $PLATFORM set to your target architecture, that should give you
components that can analyze cross-architecture binaries (but not native
ones). (Note: it is likely that there will be some kinks to work out
there; if/when you run into trouble, please let us know.)
Improving this support has long been on our TODO list; the right thing
is to get rid of any lingering per-architecture conditional compilation
and properly abstract the platform-specific bits into classes (with
machinery to auto-detect, as you note). This could happen for 9.0 but
almost certainly not for 8.2.
