gdb: Enable and Disable Tracepoints

 
 13.1.2 Enable and Disable Tracepoints
 -------------------------------------
 
 These commands are deprecated; they are equivalent to plain 'disable'
 and 'enable'.
 
 'disable tracepoint [NUM]'
      Disable tracepoint NUM, or all tracepoints if no argument NUM is
      given.  A disabled tracepoint will have no effect during a trace
      experiment, but it is not forgotten.  You can re-enable a disabled
      tracepoint using the 'enable tracepoint' command.  If the command
      is issued during a trace experiment and the debug target has
      support for disabling tracepoints during a trace experiment, then
      the change will be effective immediately.  Otherwise, it will be
      applied to the next trace experiment.
 
 'enable tracepoint [NUM]'
      Enable tracepoint NUM, or all tracepoints.  If this command is
      issued during a trace experiment and the debug target supports
      enabling tracepoints during a trace experiment, then the enabled
      tracepoints will become effective immediately.  Otherwise, they
      will become effective the next time a trace experiment is run.
