- <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)
- </p>
- <div class="example">
- <pre class="example">mov.l bar,r0
- </pre></div>
-
- <p>where other assemblers might require an explicit displacement to
- <code>bar</code> from the program counter:
- </p>
- <div class="example">
- <pre class="example">mov.l @(<var>disp</var>, PC)
- </pre></div>
