I think the better solution should be:
LLVMContext& C = is->getContext();
Value *values[] = {
ConstantInt::getSigned(Type::getInt64Ty(C), *scsr*),
MDString::get(C, *"path"*)
};
lnstr.setMetadata(*"your_analysis_name"*, MDNode::get(C, values));
So that you can take advantage of the type system of LLVM bitcode, and
don't have to cast the integers from/to strings by yourself.

Yes, it sounds good. I can try tomorrow. Thank you for your advice !

Thank you very much ! It works ! And also I can get metadata accordingly.
