the DominanceFrontierBase class constructor specifies a parameter isPostDom which I assume builds the reverse dominance frontier<br><br><div class="gmail_quote">On Tue, Jun 2, 2009 at 2:38 PM, Mark Lacey <span dir="ltr"><<a href="mailto:superoptimizer@gmail.com">superoptimizer@gmail.com</a>></span> wrote:<br>

<br>It doesn't look like LLVM currently provides a way to build the post-dominance frontier of the reverse CFG, either. Dominators.h mentions forward dominators, but I believe all this is referring to is dominators as opposed to post-dominators, not dominators on the CFG versus dominators on the reverse-CFG.<br>
<br>I just wanted to make certain I'm not overlooking anything before I decide if I want to go off and build this myself.<br><br>Thanks,<br><font color="#888888"><br>Mark<br><br>
