Not very > convenient, but you can do it. 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. -- Nate Eldredge neldredge AT hmc DOT edu
