"Debugging stubs for supporting tracepoint"

[xinan tang]

Hi



Hi 

  The following is except from doc., "Debugging with GDB":

____________________________________________________________ 
The tracepoint facility is currently available only for remote targets. 
See Chapter 16[Targets], page 143. In addition, your remote target 
must know how to collect trace data. This functionality is implemented
in the remote stub; however, none of the stubs distributed
with gdb support tracepoints as of this writing.
This chapter describes the tracepoint commands and features.
------------------------------------------------------------------

  Then question is where to get start if one wants to implement
tracepoint support on remote stubs?

Thanks
