We don't currently support tracing at that level, I'm afraid.
(There are some patches on list starting to explore providing
an API for doing this kind of instrumentation, but they're
still at the "working out a design" stage.)
You might want to look at the -d options, which can give
you register dumps before every executed instruction if
you pick the right set of options (-d exec,cpu,nochain
-singlestep is probably a start.)
