        <pre>Here's what buildSwitch() in the LLVM IR generator will look like:


void buildSwitch(LValue expression, const Vector&lt;int64_t&gt;&amp; cases, const Vector&lt;LBasicBlock&gt;&amp; targets, LBasicBlock defaultTarget)

{

    Vector&lt;FTL::SwitchCase&gt; switchCases;

    switchCases.reserveInitialCapacity(cases.size());

    for (size_t i = 0; i &lt; cases.size(); ++i)

        switchCases.uncheckedAppend(FTL::SwitchCase(m_out.constInt32(static_cast&lt;int32_t&gt;(cases[i])), targets[i]));

    m_out.switchInstruction(expression, switchCases, defaultTarget, FTL::Weight());

}</pre>
