[LLVMdev] Runtime exception in DominatorTree.getRootNode()

Hi all,

I am trying to traverse a dominator tree and have encountered a weird
runtime exception:

Here's my simple code:

    virtual bool runOnFunction(Function &F) {
      DominatorTree& DT = getAnalysis<DominatorTree>();

  *    DomTreeNode* rootNode = DT.getRootNode();*
      return false.
}

Here's the documentation page:
http://llvm.org/docs/doxygen/html/classllvm_1_1DominatorTree.html

And here's my runtime exception:
dyld: lazy symbol binding failed: Symbol not found:
__ZN4llvm17DominatorTreeBaseINS_10BasicBlockEE11getRootNodeEv
  Referenced from:
/Users/weibohe/Projects/llvm/llvm/Debug+Asserts/lib/LLVMSLVN.dylib

Any idea on why this is happening? Any help or suggestion is appreciated!

How are you running your pass?  Based on the error, it looks like 
whatever tool you're using to run your pass doesn't have the library 
defining the DominatorTree code linked in.

[LLVMdev] Runtime exception in DominatorTree.getRootNode()

Thanks for your reply, John.

I am using opt to run my pass. Should opt by default link in the library?
Would you please give me some idea on fixing it? Thanks!

opt -load ../../../Debug+Asserts/lib/LLVMHello.dylib -hello < hello.bc >
/dev/null

 My pass is just:

#include "llvm/IR/Function.h"
#include "llvm/Pass.h"
#include "llvm/Support/raw_ostream.h"
#include "llvm/Analysis/Dominators.h"

using namespace llvm;

namespace {
  struct Hello : public FunctionPass {
    static char ID;
    Hello() : FunctionPass(ID) { }
    virtual void getAnalysisUsage(AnalysisUsage &AU) const {
      AU.addRequired<DominatorTree>();
    }
    virtual bool runOnFunction(Function &F) {
      DominatorTree& DT = getAnalysis<DominatorTree>();
      BasicBlock* BB = DT.getRoot();
      return false;
    }
  };
}
char Hello::ID = 0;
static RegisterPass<Hello> Z("hello", "My test
analysis", true, true);
