Classes
class	LiveDebugValues::DebugVariableMap
	Mapping from DebugVariable to/from a unique identifying number. More...
class	LiveDebugValues::LocIdx
	Handle-class for a particular "location". More...
struct	LiveDebugValues::SpillLoc
class	LiveDebugValues::ValueIDNum
	Unique identifier for a value defined by an instruction, as a value type. More...
struct	llvm::DenseMapInfo< LocIdx >
struct	llvm::DenseMapInfo< ValueIDNum >
struct	LiveDebugValues::FuncValueTable
	A collection of ValueTables, one per BB in a function, with convenient accessor methods. More...
class	LiveDebugValues::SpillLocationNo
	Thin wrapper around an integer – designed to give more type safety to spill location numbers. More...
class	LiveDebugValues::DbgValueProperties
	Meta qualifiers for a value. More...
struct	LiveDebugValues::DbgOp
	TODO: Might pack better if we changed this to a Struct of Arrays, since MachineOperand is width 32, making this struct width 33. More...
struct	LiveDebugValues::ResolvedDbgOp
	A DbgOp whose ID (if any) has resolved to an actual location, LocIdx. More...
struct	LiveDebugValues::DbgOpID
	An ID used in the DbgOpIDMap (below) to lookup a stored DbgOp. More...
struct	LiveDebugValues::DbgOpID::IsConstIndexPair
class	LiveDebugValues::DbgOpIDMap
	Class storing the complete set of values that are observed by DbgValues within the current function. More...
class	LiveDebugValues::DbgValue
	Class recording the (high level) value of a variable. More...
class	LiveDebugValues::LocIdxToIndexFunctor
class	LiveDebugValues::MLocTracker
	Tracker for what values are in machine locations. More...
class	LiveDebugValues::MLocTracker::MLocIterator
	Iterator for locations and the values they contain. More...
class	LiveDebugValues::MLocTracker::MLocIterator::value_type
class	LiveDebugValues::VLocTracker
	Collection of DBG_VALUEs observed when traversing a block. More...
class	LiveDebugValues::InstrRefBasedLDV
