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

◆ contains() [2/2]

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

◆ 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.

unsigned llvm::MCRegisterClass::getNumRegs ( ) const
inline

getNumRegs - Return the number of registers in this class.

Definition at line 58 of file MCRegisterInfo.h.

◆ 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.
