Detailed Description

template<typename ValueT>
class llvm::MIBundleOperandIteratorBase< ValueT >

MIBundleOperandIteratorBase - Iterator that visits all operands in a bundle of MachineInstrs.

This class is not intended to be used directly, use one of the sub-classes instead.

Intended use:

for (MIBundleOperands MIO(MI); MIO.isValid(); ++MIO) { if (!MIO->isReg()) continue; ... }

Definition at line 94 of file MachineInstrBundle.h.
