<h3 class="section">23.1 Loading Plugins</h3>
|
|
|
|
<p>Plugins are supported on platforms that support <samp>-ldl
|
|
-rdynamic</samp>. They are loaded by the compiler using <code>dlopen</code>
|
|
and invoked at pre-determined locations in the compilation
|
|
process.
|
|
</p>
|
|
<p>Plugins are loaded with
|
|
</p>
|
|
<p><samp>-fplugin=/path/to/<var>name</var>.so</samp> <samp>-fplugin-arg-<var>name</var>-<var>key1</var>[=<var>value1</var>]</samp>
|
|
</p>
|
|
<p>The plugin arguments are parsed by GCC and passed to respective
|
|
plugins as key-value pairs. Multiple plugins can be invoked by
|
|
specifying multiple <samp>-fplugin</samp> arguments.
|
|
</p>
|
|
<p>A plugin can be simply given by its short name (no dots or
|
|
slashes). When simply passing <samp>-fplugin=<var>name</var></samp>, the plugin is
|
|
loaded from the <samp>plugin</samp> directory, so <samp>-fplugin=<var>name</var></samp> is
|
|
the same as <samp>-fplugin=`gcc -print-file-name=plugin`/<var>name</var>.so</samp>,
|
|
using backquote shell syntax to query the <samp>plugin</samp> directory.
|
|
