...ass class not registered! The error goes away if I take out that "addRequired". The code for the LiveVars pass includes RegisterPass<LiveVars> X("liveVars", "Live vars analysis", true, true); and I can run the LiveVars pass like this: opt -load Debug/lib/dataflowAnalysis.so -f -analyze -liveVars ... I've tried running the RemoveUseless pass with various combinations of flags (just -removeUseless, both -liveVars and -removeUseles, with and without -analyze), but I always get the same error. Any help will be much appreciated!
