| A ‘<samp><span class="samp">$</span></samp>’ character may always prefix a general or special |
| register name in an instruction operand but is mandatory when |
| the option <samp><span class="option">--no-underscore</span></samp> is specified or when the |
| <code>.syntax register_prefix</code> directive is in effect |
| (see <a href="crisnous.html#crisnous">crisnous</a>). Register names are case-insensitive. |
