+<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.
