-<h1>binop/lit16</h1>
-
-<h2>Purpose</h2>
-
-<p>
-Perform the indicated binary op on the indicated register (first argument) and
-literal value (second argument), storing the result in the destination register.
-</p>
-
-<h2>Details</h2>
-
-<table class="instruc">
-<thead>
-<tr>
- <th>Op & Format</th>
- <th>Mnemonic / Syntax</th>
- <th>Arguments</th>
-</tr>
-</thead>
-<tbody>
-<tr>
- <td>d0..d7 22s</td>
- <td><i>binop</i>/lit16 vA, vB, #+CCCC<br/>
- d0: add-int/lit16<br/>
- d1: rsub-int (reverse subtract)<br/>
- d2: mul-int/lit16<br/>
- d3: div-int/lit16<br/>
- d4: rem-int/lit16<br/>
- d5: and-int/lit16<br/>

- <td><code>A:</code> destination register (4 bits)<br/>
- <code>B:</code> source register (4 bits)<br/>
- <code>C:</code> signed int constant (16 bits)</td>
-</tr>
-</tbody>
-</table>
-
-<h2>Constraints</h2>
-
-<ul>
- <li>
- Both A and B must be valid register indices in the current stackframe.
- </li>
- <li>
- Registers vA and vB must be defined. They must both contain integer values.
- </li>
- <li>
- C is an immediate, signed integer constant taken from the instruction stream
- (actually this means there are no special requirements for C at all).
- </li>
-</ul>
-
-<h2>Behavior</h2>
-
-<ul>
- <li>
- The given operation <binop> is performed according to the semantics
- specified in table XXX.
- </li>
- <li>
- Argument C is sign-extended to 32 bits before.
- </li>
- <li>
- The result is stored in register vA, that is, vA'=vB <binop> vC.
- </li>
- <li>
- As usual, neighboring registers might get undefined, if vA was part of a
- register pair originally.
- </li>
-</ul>
-
-<h2>Exceptions</h2>
-
-<ul>
- <li>
- ArithmeticException if an error occurs during the instruction.
- </li>
-</ul>
