  20    <p>Alpha- and MIPS-based computers use an unusual stack frame, which
  21 sometimes requires GDB to search backward in the object code to
  22 find the beginning of a function.
  23
  24    <p>To improve response time (especially for embedded applications, where
  25 GDB may be restricted to a slow serial line for this search)
  26 you may want to limit the size of this search, using one of these
  27 commands:
  28
  29      <dl>
  30 <dt><code>set heuristic-fence-post </code><var>limit</var><code></code>
  31      <dd>Restrict GDB to examining at most <var>limit</var> bytes in its
  32 search for the beginning of a function.  A value of <var>0</var> (the
  33 default) means there is no limit.  However, except for <var>0</var>, the
  34 larger the limit the more bytes <code>heuristic-fence-post</code> must search
  35 and therefore the longer it takes to run.
  36
  37      <br><dt><code>show heuristic-fence-post</code>
  38      <dd>Display the current limit.
  39 </dl>
  40
  41 <p>These commands are available <em>only</em> when GDB is configured
  42 for debugging programs on Alpha or MIPS processors.
