  19
  20    <p>Before running such a <dfn>trace experiment</dfn>, an arbitrary number of
  21 tracepoints can be set.  Like a breakpoint (see <a href="Set-Breaks.html#Set%20Breaks">Set Breaks</a>), a
  22 tracepoint has a number assigned to it by GDB.  Like with
  23 breakpoints, tracepoint numbers are successive integers starting from
  24 one.  Many of the commands associated with tracepoints take the
  25 tracepoint number as their argument, to identify which tracepoint to
  26 work on.
  27
  28    <p>For each tracepoint, you can specify, in advance, some arbitrary set
  29 of data that you want the target to collect in the trace buffer when
  30 it hits that tracepoint.  The collected data can include registers,
  31 local variables, or global data.  Later, you can use GDB
  32 commands to examine the values these data had at the time the
  33 tracepoint was hit.
  34
  35    <p>This section describes commands to set tracepoints and associated
  36 conditions and actions.
