	their registers.

  Any number of actions may be packed together in a single @samp{QTDP}
  packet, as long as the packet does not exceed the maximum packet
! length (400 bytes, for many stubs).  There may be only one @samp{R}
! action per tracepoint, and it must precede any @samp{M} or @samp{X}
! actions.  Any registers referred to by @samp{M} and @samp{X} actions
! must be collected by a preceding @samp{R} action.  (The
! ``while-stepping'' actions are treated as if they were attached to a
! separate tracepoint, as far as these restrictions are concerned.)
