Actually I'm not so sure about that. I found the phi-opt infrastructure much better suited to do the necessary pattern matching, so I only thought of the conditional store replacement as enabling transformation. Also tree-if-conv only handles loops (and only inner ones), not general conditional patterns. Something which might be fixable with some amount of work, but the phi-opt infrastructure simply was already there. Ciao, Michael.
