This make is obivious that a class was not intended to be derived from. NPM analysis pass can unfortunately not marked as final because they are derived from a llvm::Checker<T> template internally by the NPM. Also normalize the use of classes/structs * NPM passes are structs * Legacy passes are classes * structs that have methods and are not a visitor pattern are classes * structs have public inheritance by default, remove "public" keyword * Use typedef'ed type instead of inline forward declaration
