The interface between the copy_ routines and the install_ routines
seems a bit odd in some cases: mostly, values are just passed as
arguments, but in some cases, they are passed via displaced_step_closure
fields.

I'd prefer if this were handled in a regular manner: the copy_
routines parse the insn text, extract all required information
and pass it all as arguments to the install_ routine.  The
install_ routine then stores all information that is needed
by the cleanup_ routine into the displaced_step_closure struct.

Otherwise, the split seems OK to me.

Bye,
Ulrich
