-<h1>move-result-wide</h1>
-
-<h2>Purpose</h2>
-
-<p>
-Move the double-word result of the most recent invoke-kind into the indicated
-register pair. This must be done as the instruction immediately after an
-invoke-kind whose (double-word) result is not to be ignored; anywhere else is
-invalid.
-</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>0b 11x</td>
- <td>move-result-wide vAA</td>
- <td><code>A:</code> destination register pair (8 bits)</td>
-</tr>
-</tbody>
-</table>
-
-<h2>Constraints</h2>
-
-<ul>
- <li>
- A+1 must be a valid register index in the current stack frame (which
- includes A itself being valid).
- </li>
- <li>
- The instruction must be immediately preceded (in the code array) by an
- invoke-kind instruction.
- </li>
- <li>
- The instruction must be immediately reached (in the actual control flow)
- through returning from this invoke-kind instruction (it must not be jumped
- to).
- </li>
- <li>
- The result delivered by the invoke-kind instruction must be either a long
- or a double value.
- </li>
-</ul>
-
-<h2>Behavior</h2>
-
-<ul>
- <li>
- The upper 32 bits of the result delivered by the invoke-kind instruction are
- moved to register vA, that is, vA' = result >> 0x20.
- </li>
- <li>
- The lower 32 bits of the result delivered by the invoke-kind instruction are
- moved to register v(A+1), that is, v(A+1)' = result & 0xffffffff.
- </li>
- <li>
- If register v(A-1) is the lower half of a register pair, register v(A-1)'
- becomes undefined.
- </li>
- <li>
- If register v(A+2) is the upper half of a register pair, register v(A+2)'
- becomes undefined.
- </li>
-</ul>
-
-<h2>Exceptions</h2>
-
-<p>
-None.
-</p>
-
-<h2>Notes</h2>
-
-<p>
-This instruction can also be thought of as reading the contents of a special
-"result" register that is made valid and defined by executing a non-void return
-instruction or a filled-new-array instruction. The execution of any other
-instruction (including this one) renders this special register invalid.
