[LLVMdev] Problems creating a pass

[Scott Ricketts]

Did you try changing the name from Hello to MyHello or something like
that? I seem to remember having a similar problem. My tutorial code
names the struct MyHello and then registers it as follows:

RegisterPass<MyHello> X("myhello", "My Hello World Pass");

You will likely need to change the Makefile as well.
