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.
