LLVM_ABI void	setup ()
LLVM_ABI void	cleanup ()
LLVM_ABI void	calculateDroppedStatsAndPrint (DebugVariables &DbgVariables, StringRef FuncName, StringRef PassID, StringRef FuncOrModName, StringRef PassLevel, const Function *Func)
	Calculate the number of dropped variables in an llvm::Function or llvm::MachineFunction and print the relevant information to stdout.
LLVM_ABI bool	updateDroppedCount (DILocation DbgLoc, const DIScope Scope, const DIScope DbgValScope, DenseMap< VarID, DILocation > &InlinedAtsMap, VarID Var, unsigned &DroppedCount)
	Check if a `Var` has been dropped or is a false positive.
LLVM_ABI void	run (DebugVariables &DbgVariables, StringRef FuncName, bool Before)
	Run code to populate relevant data structures over an llvm::Function or llvm::MachineFunction.
LLVM_ABI void	populateVarIDSetAndInlinedMap (const DILocalVariable DbgVar, DebugLoc DbgLoc, DenseSet< VarID > &VarIDSet, DenseMap< StringRef, DenseMap< VarID, DILocation > > &InlinedAtsMap, StringRef FuncName, bool Before)
	Populate the VarIDSet and InlinedAtMap with the relevant information needed for before and after pass analysis to determine dropped variable status.
Protected Attributes inherited from llvm::DroppedVariableStats
bool	DroppedVariableStatsEnabled = false
SmallVector< DenseMap< const Function *, DebugVariables > >	DebugVariablesStack
	A stack of a DenseMap, that maps DebugVariables for every pass to an llvm::Function.
DenseSet< const DIScope * >	VisitedScope
	A DenseSet tracking whether a scope was visited before.
SmallVector< DenseMap< StringRef, DenseMap< VarID, DILocation * > > >	InlinedAts
	A stack of DenseMaps, which map the name of an llvm::Function to a DenseMap of VarIDs and their inlinedAt locations before an optimization pass has run.
