implementing stepi

["Decker, Paul" <Paul dot Decker at analog dot com>]

hello everyone,

I have what I believe is a simple question on the implementation of the
stepi feature.  Some processors provide a mechanism to step exactly one
instruction, such as a special bit in a debug control register.  While
other processors don't provide this capability, and to implement a step,
breakpoints must be sprinkled in various places, and a run (to the
breakpoint) performed.   Looking at some of the gdb source, it seems
that stepi is implemented using the breakpoint method.  In doing a port
to my custom processor, is it considered ok to use the hardware method
if available?

Thanks,
Paul.
