<p>
Load- and store-multiple instructions operate on a range of registers.
The range of registers is specified by a start register and an end register.
For example, <code>LMG</code> <code>(R9),</code> <code>R5,</code> <code>R7</code> would load
<code>R5</code>, <code>R6</code> and <code>R7</code> with the 64-bit values at
<code>0(R9)</code>, <code>8(R9)</code> and <code>16(R9)</code> respectively.
