You have to do two things to make use of the JIT support in the simplest way:
<pre>
  (1) Call <b>pcre_study()</b> with the PCRE_STUDY_JIT_COMPILE option for
      each compiled pattern, and pass the resulting <b>pcre_extra</b> block to
      <b>pcre_exec()</b>.

  (2) Use <b>pcre_free_study()</b> to free the <b>pcre_extra</b> block when it is
      no longer needed, instead of just freeing it yourself. This ensures that
      any JIT data is also freed.
