Detailed Description

DiffListIterator - Base iterator class that can traverse the differentially encoded register and regunit lists in DiffLists.

Don't use this class directly, use one of the specialized sub-classes defined below.

Definition at line 187 of file MCRegisterInfo.h.

Constructor & Destructor Documentation

DiffListIterator()

llvm::MCRegisterInfo::DiffListIterator::DiffListIterator ( )

protecteddefault

Create an invalid iterator. Call init() to point to something useful.

Member Function Documentation

advance()

unsigned llvm::MCRegisterInfo::DiffListIterator::advance ( )

inlineprotected

advance - Move to the next list position, return the applied differential.

This function does not detect the end of the list, that is the caller's responsibility (by checking for a 0 return value).

Definition at line 206 of file MCRegisterInfo.h.

References assert(), and D.

init()

void llvm::MCRegisterInfo::DiffListIterator::init ( MCPhysReg  InitVal, const MCPhysReg *  DiffList  )

inlineprotected

init - Point the iterator to InitVal, decoding subsequent values from DiffList.

The iterator will initially point to InitVal, sub-classes are responsible for skipping the seed value if it is not part of the list.

Definition at line 198 of file MCRegisterInfo.h.

isValid()

bool llvm::MCRegisterInfo::DiffListIterator::isValid ( ) const

inline

isValid - returns true if this iterator is not yet at the end.

Definition at line 215 of file MCRegisterInfo.h.

operator*()

unsigned llvm::MCRegisterInfo::DiffListIterator::operator* ( ) const

inline

Dereference the iterator to get the value at the current position.

Definition at line 218 of file MCRegisterInfo.h.

operator++()

void llvm::MCRegisterInfo::DiffListIterator::operator++ ( )

inline

Pre-increment to move to the next position.
