It generally works except, AFAIK, when making a call where both the
callee and the caller don't have debug information. In such a situation,
executing a step while stopped at a CALL instruction produces the wrong
disassembly.
There are other GDB commands too (such as NEXTI) that don't work when
both the caller and callee don't have debug information, that I'm trying
to fix (in GDB); and would prefer to fix GUD-MI (to display a few
instructions before $PC) once GDB works as expected in these cases. What
do you think?
