[LLVMdev] issue writing llvm metadata

I am looking to write customized metadata to a particular load instruction using LLVM transform pass (A function pass to be specific). I have the following code snippet.
> Value *CI = ConstantInt::get(getGlobalContext(), APInt(8,2));
> ArrayRef<Value*> temp = ArrayRef<Value*>( CI);
> MDNode *Node = MDNode::get(load->getContext(), temp);
On running the pass with my input_file, I could not find the new metadata node in the .o file when i run llvm-dis with it . What am I missing ? Please help me out!
I run the pass as
opt -load path_to_my_library.so -pass_name < input_file.o > /dev/null
Should I do something different for a transform pass to work?
