<h4 class="section">D30V Options</h4>



   <p>The Mitsubishi D30V version of <code>as</code> has a few machine

dependent options.



     <dl>

<dt><code>-O</code>

     <dd>The D30V can often execute two sub-instructions in parallel. When this option

is used, <code>as</code> will attempt to optimize its output by detecting when

instructions can be executed in parallel.



     <br><dt><code>-n</code>

     <dd>When this option is used, <code>as</code> will issue a warning every

time it adds a nop instruction.



     <br><dt><code>-N</code>

     <dd>When this option is used, <code>as</code> will issue a warning if it

needs to insert a nop after a 32-bit multiply before a load or 16-bit

multiply instruction.
