[LLVMdev] Analysis Pass

[Rotem Varon]

Hi,

I am trying to set a prerequisite pass.


void PassName::getAnalysisUsage(AnalysisUsage &AU) const
    {
        AU.setPreservesAll();
        AU.addRequired<LiveVariables>();
    }

But when i am running the pass with the opt i get this error:
undefined symbol: _ZN4llvm13LiveVariables2IDE

If you need more information ...

Thank you.
