...ing to use LLVM's AliasAnalysis pass, but from a standalone tool that uses llvm libraries. The following is the code snippet I am currently using. PassBuilder PB; auto mod_manager = ModuleAnalysisManager { }; PB.registerModuleAnalyses(mod_manager); AAResults& AAR = mod_manager.getResult<AAManager>(*M); But the code fails at .getResult with the following error: /llvm/include/llvm/IR/PassManager.h:778: typename PassT::Result& llvm::AnalysisManager<IRUnitT, ExtraArgTs>::getResult(IRUnitT&, ExtraArgTs ...) [with PassT = llvm::AAManager; IRUnitT = llvm::Module; ExtraArgTs = {...

Hi! I am trying to extend the native AliasAnalysis of LLVM to use an external analysis pass. Doing this with the legacy pass manager works fine through calling addRequired() in the getAnalysisUsage and getAnalysis() in function runOnFunction(). In the new pass manager, I haven't found a similar way of doing this. When running opt with -O3, I encounter the following error: >Assertion
