Public Member Functions
LLVM_ABI void	reset ()
	Clear the result so it can be used for another round of pressure tracking.
LLVM_ABI void	openTop (MachineBasicBlock::const_iterator PrevTop)
	If the current top is the previous instruction (before receding), open it.
LLVM_ABI void	openBottom (MachineBasicBlock::const_iterator PrevBottom)
	If the current bottom is the previous instr (before advancing), open it.
Public Member Functions inherited from llvm::RegisterPressure
LLVM_ABI void	dump (const TargetRegisterInfo *TRI) const

Public Attributes
MachineBasicBlock::const_iterator	TopPos
	Record the boundary of the region being tracked.
MachineBasicBlock::const_iterator	BottomPos
Public Attributes inherited from llvm::RegisterPressure
std::vector< unsigned >	MaxSetPressure
	Map of max reg pressure indexed by pressure set ID, not class ID.
SmallVector< VRegMaskOrUnit, 8 >	LiveInRegs
	List of live in virtual registers or physical register units.
SmallVector< VRegMaskOrUnit, 8 >	LiveOutRegs

RegisterPressure computed within a region of instructions delimited by TopPos and BottomPos.

This is a less precise version of IntervalPressure for use when LiveIntervals are unavailable.
