llvm dev - Aug 2018 - Error: ‘class llvm::PassManager<llvm::Module>’ has no member named ‘add’

Hi, I am begineer to llvm, implementing a main.cpp from
https://github.com/davidar/lljvm/blob/master/backend/main.cpp

A) : When I am declaring a command:
*       PassManager PM*
*       PM.add(new DataLayout td)*

It shows error:
>
*error: missing template arguments before ‘PM’*
*  PassManager PM;*
              ^
>*main_test.cpp:48:2: error: ‘PM’ was not declared in this scope*
*  PM.add(new DataLayout(td));*

Keeping in mind the above error, I changed the code as:
*PassManager<Module> PM*
*PM.add(new DataLayout td)*

I dont know, whether the above change is the correct one or not. But the
error is changed to:
>*error: ‘class llvm::PassManager<llvm::Module>’ has no member named
‘add’*
*  PM.add(new DataLayout(td));*

Here is mine source code:
-----------------------------------------------
#include "backened.h"
#include <iostream>
#include "llvm/Bitcode/BitcodeReader.h"
#include "llvm/IR/Function.h"
#include "llvm/IR/LLVMContext.h"
#include "llvm/IR/Module.h"
#include "llvm/Support/CommandLine.h"
#include "llvm/Support/ErrorOr.h"
#include "llvm/Support/MemoryBuffer.h"
#include "llvm/Support/raw_ostream.h"
#include "llvm/IR/PassManager.h"
#include "llvm/CodeGen/Passes.h"
#include "llvm/IR/DataLayout.h"
#include <llvm/Transforms/Scalar.h>
#include "llvm/IR/LegacyPassManager.h"

using namespace llvm;
using namespace std;

static cl::opt<string> input(cl::Positional, cl::desc("Bitcode
File.."),cl::Required);
static cl::opt<string>
classname("classname",cl::desc("Binary name of the
generated class..."));

int main(int argc, char** argv)
{
        cl::ParseCommandLineOptions(argc, argv, "Hi..");
        LLVMContext context;


        ErrorOr<unique_ptr<MemoryBuffer>>  mb
MemoryBuffer::getFile(input);
        if(error_code ec = mb.getError())
        {
                errs() << ec.message();
                return 1;
        }

        Expected<unique_ptr<Module>> m
parseBitcodeFile(mb->get()->getMemBufferRef(),context);
        if(error_code ec= errorToErrorCode(m.takeError()) )
        {
        PassManager<Module> PM;
        DataLayout td("e-p:32:32:32"
                 "-i1:8:8-i8:8:8-i16:16:16-i32:32:32-i64:64:64"
                 "-f32:32:32-f64:64:64");
        PM.add(new DataLayout(td));
        return 0;
}
------------------------------------------

B) Also suggest me , whether I am implemented a correct way "*DataLayout td
("e-p:32:32:32......")" *and "*new DataLayout td"  *in
the place of
TargetData.h as I found that TargeyData.h is not found in  newer version of
llvm. Thank you.

Hi Ratnesh,

the PassManager used in that example has moved into the legacy namespace:
http://llvm.org/doxygen/classllvm_1_1legacy_1_1PassManager.html

Cheers,
Philip

Hi Philip,
I also tried that including file:
#include "llvm/IR/LegacyPassManager.h"
but error remain same. Please help.
