<p>The Mitsubishi D30V version of <code>as</code> has a few machine
dependent options.
</p>
<dl compact="compact">
<dt>&lsquo;<samp>-O</samp>&rsquo;</dt>
<dd><p>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.
</p>
</dd>
<dt>&lsquo;<samp>-n</samp>&rsquo;</dt>
<dd><p>When this option is used, <code>as</code> will issue a warning every
time it adds a nop instruction.
</p>
</dd>
<dt>&lsquo;<samp>-N</samp>&rsquo;</dt>
<dd><p>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.
