There are a few tricks for using gdb with assembly.  For instance, you
can use $ with register names; `p $eax' will print the contents of
eax.  Another useful trick is `display /i $pc'; this will make it
disassemble the current instruction whenever you stop, or as you
single-step.  I think these are in the manual somewhere.
