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 188 of file MCRegisterInfo.h.

Constructor & Destructor Documentation

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

inlineprotected

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

Definition at line 194 of file MCRegisterInfo.h.

Member Function Documentation

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 207 of file MCRegisterInfo.h.

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.

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