Member Function Documentation

void LiveDebugVariables::dump

(

)

dump - Print data structures to dbgs().

Definition at line 1017 of file LiveDebugVariables.cpp.

References llvm::dbgs(), and llvm::Pass::print().

void LiveDebugVariables::emitDebugValues

(

VirtRegMap *

VRM

)

emitDebugValues - Emit new DBG_VALUE instructions reflecting the changes that happened during register allocation.

Parameters:

VRM	Rename virtual registers according to map.

Definition at line 1006 of file LiveDebugVariables.cpp.

void llvm::LiveDebugVariables::renameRegister	(	unsigned	OldReg,
		unsigned	NewReg,
		unsigned	SubIdx
	)

renameRegister - Move any user variables in OldReg to NewReg:SubIdx.

Parameters:

OldReg	Old virtual register that is going away.
NewReg	New register holding the user variables.
SubIdx	If NewReg is a virtual register, SubIdx may indicate a sub- register.

void LiveDebugVariables::splitRegister	(	unsigned	OldReg,
		ArrayRef< unsigned >	NewRegs,
		LiveIntervals &	LIS
	)

splitRegister - Move any user variables in OldReg to the live ranges in NewRegs where they are live. Mark the values as unavailable where no new register is live.
