llvm dev - Sep 2015 - Registering a MachineFunctionPass

Dear all,
I wrote a machine function pass to run with llc. But I get this error while
building:
"/home/erdem/llvm/lib/CodeGen/CodeGen.cpp:80: error: undefined reference to
'llvm::initializeNoopInserterPass(llvm::PassRegistry&)'"
NoopInserter is the name of my pass. I already added this line to
InitializePasses.h: "void
initializeNoopInserterPass(PassRegistry&);".
Can anyone tell me what the problem is?
Thanks in advance,Erdem Derebasoglu

The code probably misses the INITIALIZE_PASS macro, see bottom
of BarrierNoopPass.cpp

INITIALIZE_PASS(BarrierNoop, "barrier", "A No-Op Barrier
Pass",
                false, false)

I had INITIALIZE_PASS_BEGIN and INITIALIZE_PASS_END macros. I replaced them with
INITIALIZE_PASS but I get the same error. If I understand correctly, I need to
modify Passes.h, InitializePasses.h, and Codegen.cpp files to register my pass,
right? Another question is: Is it necessary to have the createNoopInserterPass
function?
