Hi, I’m writing a loop-free LLVM pass, my thought is to track if the value inside the loop is changed, so I look up the Instruction StoreInst first and try to get its value in a set. I checked getValueOperand(), getValueName() in the API document but unfortunately they failed the compilation. if (isa<StoreInst>(I)){ Value* v = I.getOperand(0); Instruction* op1 =
