Functions
static int	clang::dataflow::blockIndexInPredecessor (const CFGBlock &Pred, const CFGBlock &Block)
	Returns the index of `Block` in the successors of `Pred`.

static bool	clang::dataflow::isBackedgeNode (const CFGBlock &B)

static const Expr *	clang::dataflow::getTerminatorCondition (const Stmt *TerminatorStmt)

static TypeErasedDataflowAnalysisState	clang::dataflow::computeBlockInputState (const CFGBlock &Block, AnalysisContext &AC)
	Computes the input state for a given basic block by joining the output states of its predecessors.

static void	clang::dataflow::builtinTransferStatement (unsigned CurBlockID, const CFGStmt &Elt, TypeErasedDataflowAnalysisState &InputState, AnalysisContext &AC)
	Built-in transfer function for `CFGStmt`.

static void	clang::dataflow::builtinTransferInitializer (const CFGInitializer &Elt, TypeErasedDataflowAnalysisState &InputState)
	Built-in transfer function for `CFGInitializer`.

static void	clang::dataflow::builtinTransfer (unsigned CurBlockID, const CFGElement &Elt, TypeErasedDataflowAnalysisState &State, AnalysisContext &AC)

static TypeErasedDataflowAnalysisState	clang::dataflow::transferCFGBlock (const CFGBlock &Block, AnalysisContext &AC, std::function< void(const CFGElement &, const TypeErasedDataflowAnalysisState &)> PostVisitCFG=nullptr)
	Transfers `State` by evaluating each element in the `Block` based on the `AC.Analysis` specified.

llvm::Expected< std::vector< std::optional< TypeErasedDataflowAnalysisState > > >	clang::dataflow::runTypeErasedDataflowAnalysis (const AdornedCFG &ACFG, TypeErasedDataflowAnalysis &Analysis, const Environment &InitEnv, std::function< void(const CFGElement &, const TypeErasedDataflowAnalysisState &)> PostVisitCFG, std::int32_t MaxBlockVisits)
	Performs dataflow analysis and returns a mapping from basic block IDs to dataflow analysis states that model the respective basic blocks.
