Member Function Documentation

iterator llvm::MCRegisterClass::begin ( ) const [inline]

begin/end - Return all of the registers in this class.

Definition at line 55 of file MCRegisterInfo.h.

References RegsBegin.

Referenced by llvm::TargetRegisterClass::begin(), and getReg().

bool llvm::MCRegisterClass::contains ( unsigned Reg ) const [inline]

contains - Return true if the specified register is included in this register class. This does not include virtual registers.

Definition at line 71 of file MCRegisterInfo.h.

References RegSet, and RegSetSize.

Referenced by llvm::TargetRegisterClass::contains(), contains(), llvm::MCRegisterInfo::getMatchingSuperReg(), llvm::ARMInstPrinter::printInst(), llvm::AArch64InstPrinter::printVectorList(), and llvm::MipsRegInfoRecord::SetPhysRegUsed().

bool llvm::MCRegisterClass::contains	(	unsigned	Reg1,
		unsigned	Reg2
	)		const `[inline]`

contains - Return true if both registers are in this class.

Definition at line 80 of file MCRegisterInfo.h.

References contains().

iterator llvm::MCRegisterClass::end ( ) const [inline]

Definition at line 56 of file MCRegisterInfo.h.

References RegsBegin, and RegsSize.

Referenced by llvm::TargetRegisterClass::end().

unsigned llvm::MCRegisterClass::getAlignment ( ) const [inline]

getAlignment - Return the minimum required alignment for a register of this class.

Definition at line 90 of file MCRegisterInfo.h.

References Alignment.

Referenced by llvm::TargetRegisterClass::getAlignment().

int llvm::MCRegisterClass::getCopyCost ( ) const [inline]

getCopyCost - Return the cost of copying a value between two registers in this class. A negative number means the register class is very expensive to copy e.g. status flag register classes.

Definition at line 95 of file MCRegisterInfo.h.

References CopyCost.

Referenced by llvm::TargetRegisterClass::getCopyCost().

unsigned llvm::MCRegisterClass::getID ( ) const [inline]

getID() - Return the register class ID number.

Definition at line 47 of file MCRegisterInfo.h.

References ID.

Referenced by llvm::TargetRegisterClass::getID().

const char* llvm::MCRegisterClass::getName ( ) const [inline]

getName() - Return the register class name for debugging.

Definition at line 51 of file MCRegisterInfo.h.

References Name.
