Constructor & Destructor Documentation

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.
