<h1>move-result-object</h1>
<h2>Purpose</h2>
<p>
Move the object result of the most recent invoke-kind into the indicated
register. This must be done as the instruction immediately after an invoke-kind
or filled-new-array whose (object) result is not to be ignored; anywhere else
is invalid.

<h2>Constraints</h2>
<ul>
<li>
A must be a valid register index in the current stack frame.
</li>
<li>
The instruction must be immediately preceded (in the code array) by an
invoke-kind, filled-new-array, or filled-new-array/range instruction.
</li>
<li>
The instruction must be immediately reached (in the actual control flow)
through returning from this invoke-kind instruction or by passing a
filled-new-array or filled-new-array/range instruction (it must not be
jumped to).
</li>
<li>
The result delivered by the invoke-kind instruction must be a reference
value (which excludes the case of a long and double values).
</li>
</ul>
<h2>Behavior</h2>
<ul>
<li>
The result delivered by the invoke-kind instruction is moved to register
vA, that, is vA' = result.
</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+1) is the upper half of a register pair, register v(A+1)'
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.
