<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 class="noindent">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>
