Hi, I'm writing a ModulePass that needs critical edges split up. I have the statement AU.addRequiredID(BreakCriticalEdgesID); in my getAnalysisUsage() but the pass never gets executed. I guess I have to request pass execution for each function, but I can't get behind how to do that, since there is no analysis group for that kind of transformation. Thanks, Andi

Dear llvm guys, I am trying to add the BreakCriticalEdges pass to my application. I tried to add it to the PNE pass (e.g. PHIElimination.cpp - AU.addRequiredID(BreakCriticalEdgesID); ), but I get this error: llc -f -regalloc=simple Base1Sum.bc -o simple.s ----------------------------------------------- llc: PassManagerT.h:387: void llvm::PassManagerT<Trait>::markPassUsed(const llvm::PassInfo*, llvm::Pass*) [with Trait = llvm::MTraits]: Assertion `getAnalysisOrNullUp(P)...
