<h4 class="section">D10V Options</h4>



   <p>The Mitsubishi D10V version of <code>as</code> has a few machine

dependent options.



     <dl>

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

     <dd>The D10V 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>--nowarnswap</code>

     <dd>To optimize execution performance, <code>as</code> will sometimes swap the

order of instructions. Normally this generates a warning. When this option

is used, no warning will be generated when instructions are swapped. 

<br><dt><code>--gstabs-packing</code>

     <dd><br><dt><code>--no-gstabs-packing</code>

     <dd><code>as</code> packs adjacent short instructions into a single packed

instruction. <code>--no-gstabs-packing</code> turns instruction packing off if

<code>--gstabs</code> is specified as well; <code>--gstabs-packing</code> (the

default) turns instruction packing on even when <code>--gstabs</code> is

specified.
