<h3 class="section">23.8 Controlling which passes are being run</h3>
|
|
|
|
<p>After the original gate function for a pass is called, its result
|
|
- the gate status - is stored as an integer.
|
|
Then the event <code>PLUGIN_OVERRIDE_GATE</code> is invoked, with a pointer
|
|
to the gate status in the <code>gcc_data</code> parameter to the callback function.
|
|
A nonzero value of the gate status means that the pass is to be executed.
|
|
You can both read and write the gate status via the passed pointer.
