LLVM has a DominatorTree analysis pass that might be useful: 
http://llvm.org/doxygen/classllvm_1_1DominatorTree.html

I also recall an actual Dominator analysis pass in previous versions of 
LLVM, but I'm unsure if it still exists in mainline LLVM.  I think it 
was replaced by some new facility in the VMCore library.

  Seems you have the same problem as [1]? Perhaps you can refer to [2]
to see how to define your own pass and use getAnalysis template to get
the function's dominator tree.
