Readers can be loaded and unloaded using the <code>jit-reader-load</code>
|
|
and <code>jit-reader-unload</code> commands.
|
|
|
|
<dl>
|
|
<dt><code>jit-reader-load </code><var>reader</var><dd>Load the JIT reader named <var>reader</var>, which is a shared
|
|
object specified as either an absolute or a relative file name. In
|
|
the latter case, <span class="sc">gdb</span> will try to load the reader from a
|
|
pre-configured directory, usually <samp><var>libdir</var><span class="file">/gdb/</span></samp> on a UNIX
|
|
system (here <var>libdir</var> is the system library directory, often
|
|
<samp><span class="file">/usr/local/lib</span></samp>).
|
|
|
|
<p>Only one reader can be active at a time; trying to load a second
|
|
reader when one is already loaded will result in <span class="sc">gdb</span>
|
|
reporting an error. A new JIT reader can be loaded by first unloading
|
|
the current one using <code>jit-reader-unload</code> and then invoking
|
|
<code>jit-reader-load</code>.
|
|
|
|
<br><dt><code>jit-reader-unload</code><dd>Unload the currently loaded JIT reader.
