<div id="yiv923616777"><div><div style="color:#000;background-color:#fff;font-family:times new roman, new york, times, serif;font-size:12pt;">Hello llvmdevs,<br><br>In a function pass, I need to visit all the basic blocks in bottom-up order (the exact opposite of ReversePostOrderTraversal). I noticed some APIs like po_iterator but wasn't able to figure out an example usage for this on web. Any pointers/suggestions are highly appreciated.<br><br>Thanks,<br>Ananth <br><div><br></div></div></div></div><br><br> </div> </div> </div></body></html>
