...w which pairs are RAW/WAR/WAW. It seems related to the approach outlined here : https://sites.google.com/site/parallelizationforllvm/building-the-dependence-graph Is there any existing implementation I can take a look at? It seems that the only the DependenceAnalysis::depends is only called in the dumpExampleDependence() function (checked using cscope). Is there no other module which uses this class?

...LVM stud to do a cleaner job, but your code looks plausible. I'll note that anything you do for a confused dependence makes sense for a full dependence. So you can test for input, output, flow, etc. If you look at the code in lib/Analysis/DependenceAnalysis.cpp you can see how I exercise DA (in dumpExampleDependence) and how I print the info associated with a dependence (in Dependence::dump) Preston -------------- next part -------------- An HTML attachment was scrubbed...
