Constructor & Destructor Documentation

◆ SuperRegClassIterator()

llvm::SuperRegClassIterator::SuperRegClassIterator ( const TargetRegisterClass RC,
const TargetRegisterInfo TRI,
bool  IncludeSelf = false 
)
inline

Create a SuperRegClassIterator that visits all the super-register classes of RC.

When IncludeSelf is set, also include the (0, sub-classes) entry.

◆ getMask()

const uint32_t* llvm::SuperRegClassIterator::getMask ( ) const
