Nope. You'd have to add one. And, you'd have to be able to tell
whether you were in the middle of a GDB-automated step or a user stepi;
stepping multiple instructions when the user asked for one is probably
just confusing.
Reading the instruction before stepping is going to slow down single
stepping. Is there some other way we can handle this?
The same problem applies to many other architectures, e.g. MIPS and ARM.
