Member Function Documentation

begin()

iterator llvm::MCRegisterClass::begin ( ) const

inline

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

Definition at line 53 of file MCRegisterInfo.h.

References RegsBegin.

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

contains() [1/2]

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.

contains() [2/2]

bool llvm::MCRegisterClass::contains ( unsigned  Reg1, unsigned  Reg2  ) const

inline

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

Definition at line 78 of file MCRegisterInfo.h.

getCopyCost()

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.

getNumRegs()

unsigned llvm::MCRegisterClass::getNumRegs ( ) const

inline

getNumRegs - Return the number of registers in this class.

Definition at line 58 of file MCRegisterInfo.h.

References RegsSize.

Referenced by llvm::TargetRegisterClass::getNumRegs(), getRegister(), and getSpecialRegForName().

getRegister()

unsigned llvm::MCRegisterClass::getRegister ( unsigned  i ) const

inline

getRegister - Return the specified register in the class.

Definition at line 62 of file MCRegisterInfo.h.

References assert(), and getNumRegs().

Referenced by doesIgnoreDataTypeSuffix(), llvm::TargetRegisterClass::getRegister(), and getSpecialRegForName().

isAllocatable()

bool llvm::MCRegisterClass::isAllocatable ( ) const
