   <p>For detailed information on the SH machine instruction set, see

<cite>SH-Microcomputer User's Manual</cite> (Hitachi Micro Systems, Inc.).



   <p><code>as</code> implements all the standard SH opcodes.  No additional

pseudo-instructions are needed on this family.  Note, however, that

because <code>as</code> supports a simpler form of PC-relative

addressing, you may simply write (for example)



<pre class="example">     mov.l  bar,r0

     </pre>



<p>where other assemblers might require an explicit displacement to

<code>bar</code> from the program counter:



<pre class="example">     mov.l  @(<var>disp</var>, PC)

     </pre>
