I suppose ltrace fits the bill.  Embedded crowd even seems to have some
interest in it (I've seen several MIPS-related bug reports over the past
year).  It's a small tool (the binary is about 200K), and linking in
close to 2M worth of libpython is something I'd rather not do.

I find the declarative approach very attractive.  Using specifically
Dwarf seems like an obvious choice.  Putting together a parser for Dwarf
expressions wouldn't be a big deal, and failing that, even the whole of
eu-libdw is not huge.

Thanks,
