<h1>binop/lit8</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.

<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>
