[LLVMdev] An error:Pass 'Runtime Evaluation' is not initialized

[王长城]

Hi,all:
I am a new at writing LLVM PASS, i write a pass like this :
using namespace llvm;


namespace {
  class RuntimeEval : public ModulePass {
  public:
    static char ID; // Pass identification, replacement for typeid


    RuntimeEval() : ModulePass(ID) {
    }
    
    virtual bool runOnModule(Module &M) {
      return false;  
    } 
  };
}


char HSASupportedRuntimeEval::ID = 0;
static RegisterPass<RuntimeEval> X("Eval", "Runtime Evaluation");


it can be compiled successful, but when i run it with command: './Release+Asserts/bin/opt -load ./Release+Asserts/lib/LLVMRuntimeEval.so -Eval < code2.bc', 


i meet an error: 


Pass 'HSA Supported Runtime Evaluation' is not initialized.

If anyone can give me some advices about it? thanks!
