-<h1>const-class</h1>
-
-<h2>Purpose</h2>
-
-<p>
-Move a reference to the class specified by the given index into the specified
-register. In the case where the indicated type is primitive, this will store a
-reference to the primitive type's degenerate class.
-</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>1c 21c</td>
- <td>const-class vAA, type@BBBB</td>
- <td><code>A:</code> destination register (8 bits)<br/>
- <code>B:</code> type index</td>
-</tr>
-</tbody>
-</table>
-
-<h2>Constraints</h2>
-
-<ul>
- <li>
- A must be a valid register index in the current stack frame.
- </li>
- <li>
- B must be a valid index into the type constant pool.
- </li>
-</ul>
-
-<h2>Behavior</h2>
-
-<ul>
- <li>
- An attempt is made to get a reference to the class C the name of which is
- contained in type pool entry B.
- </li>
- <li>
- If B refers to a primitive type, the corresponding degenerate class is used
- instead.
- </li>
- <li>
- If C has not been loaded and resolved before, it is being loaded and
- resolved. All exceptions that are possible during class loading can occur at
- this point.
- </li>
- <li>
- A reference to C is moved into register vA, that is, vA' = C.
- </li>
- <li>
- If v(A-1) is the lower half of a register pair, v(A-1)' becomes undefined.
- </li>
- <li>
- If v(A+1) is the upper half of a register pair, v(A+1)' becomes undefined.
- </li>
-</ul>
-
-<h2>Exceptions</h2>
-
-<ul>
- <li>
- ClassNotFoundException is thrown if the class does not exist at all.
- </li>
- <li>
- VerifyError is thrown if the class does exist, but could not be verified.
- </li>
-</ul>
