Since the LLVM 13 update (version 1.0), the code needs a change:

#include "cling/Interpreter/Interpreter.h"
#include "cling/Interpreter/Transaction.h"
#include "llvm/IR/Function.h"
#include "llvm/IR/Module.h"
#include "llvm/Support/raw_ostream.h"

auto T1 = gCling->getLatestTransaction();
// command
T1->getNext()->dumpPretty();
T1->getNext()->getCompiledModule()->print(llvm::outs(), nullptr);
