The `symbol *` of reduction variables and scan variables are different now. Reduction declares a private symbol as implemented [here](https://github.com/anchuraj/llvm-project/blob/master/flang/lib/Semantics/resolve-directives.cpp#L2478). So checking `Symbol *` would not be appropriate at this stage. Looking to make further modification of using the same `Symbol *` in both clauses (if required) as I proceed with the implementation.
