bool llvm::MachineOperandIteratorBase::VirtRegInfo::Reads

Reads - One of the operands read the virtual register. This does not include <undef> or <internal> use operands, see MO::readsReg().

Definition at line 156 of file MachineInstrBundle.h.

bool llvm::MachineOperandIteratorBase::VirtRegInfo::Tied

Tied - Uses and defs must use the same register. This can be because of a two-address constraint, or there may be a partial redefinition of a sub-register.
