Declared in <llvm/CodeGen/TargetRegisterInfo.h>
class BitMaskClassIterator;This class encapsulates the logic to iterate over bitmasks returned by the various RegClass related APIs. E.g., this class can be used to iterate over the subclasses provided by TargetRegisterClass::getSubClassMask or SuperRegClassIterator::getMask.
