template<typename AnalysisT >
llvm::Expected< std::vector< std::optional< DataflowAnalysisState< typename AnalysisT::Lattice > > > > clang::dataflow::runDataflowAnalysis (const ControlFlowContext &CFCtx, AnalysisT &Analysis, const Environment &InitEnv, std::function< void(const CFGElement &, const DataflowAnalysisState< typename AnalysisT::Lattice > &)> PostVisitCFG=nullptr)
 Performs dataflow analysis and returns a mapping from basic block IDs to dataflow analysis states that model the respective basic blocks.
template<typename AnalysisT , typename Diagnostic >
llvm::Expected< llvm::SmallVector< Diagnostic > > clang::dataflow::diagnoseFunction (const FunctionDecl &FuncDecl, ASTContext &ASTCtx, llvm::function_ref< llvm::SmallVector< Diagnostic >(const CFGElement &, ASTContext &, const TransferStateForDiagnostics< typename AnalysisT::Lattice > &)> Diagnoser, std::int64_t MaxSATIterations=1 '000 '000 '000)
 Runs a dataflow analysis over the given function and then runs Diagnoser over the results.
