| <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> |
