<h5>Overview:</h5>
<b>NOTE:</b> The switch instruction may go away in the future. It is not very
well supported in LLVM anyway, so don't go to great lengths to support it. Talk
to <a href="mailto:sabre@nondot.org">Chris</a> for more info if this concerns
you.<p>
The '<tt>switch</tt>' instruction is used to transfer control flow to one of
several different places. It is a generalization of the '<tt>br</tt>'
instruction, allowing a branch to occur to one of many possible destinations.<p>
