    Hi  River @River707 @tensorflower-gardener ，In `CallGraph Analysis`, I find a `AbstractEdge` will always be added to target `CallGraphNode` from `externalCallerNode`, no matter the target is a public or private `FunctionOpInterface` (which is subclass of `CallOpInterface`) . 

https://github.com/llvm/llvm-project/blob/c17a914675f8fcadbf0ef440aae7e0ab6c49ec0c/mlir/lib/Analysis/CallGraph.cpp#L125-L131

Is there any plan to add visibility for `CallOpInterface` to get better analysis result ？Or could you please give me some advice, I can try to fix this problem?
