But is there a better way of getting the loops in a function than using LoopInfo? For some tasks it is necessary that we don't process the same loop twice. Doing that with LoopInfo requires the use of a flag.<br><br><div class="gmail_quote">

A LoopPass operates on loops. It updates/deletes loops. Its end result<br>
is modified loops.<br>
A FunctionPass operates on entire function.<br>
<br>
LoopInfo is a FunctionPass that collect loops from a function. A<br>
FunctionPass can certainly request another FunctionPass such as<br>
LoopInfo.<br>
