#include "llvm/Analysis/LoopPass.h" using namespace llvm; int main() { LoopPassManager LPM; LPM.add(createLoopSimplifyPass()); // add pass }Here, the createLoopSimplifyPass function creates a pass that simplifies loops in the code. The add method is used to add this pass to a Loop Pass Manager, which will perform this analysis on each loop in the code. It's worth noting that the PassManagerBase is part of LLVM's Compiler Infrastructure library, which is a collection of packages used for creating compilers and related tools.
