◆ Clobbered
| bool llvm::MachineOperandIteratorBase::PhysRegInfo::Clobbered |

◆ DeadDef
| bool llvm::MachineOperandIteratorBase::PhysRegInfo::DeadDef |
Either:
- Reg is FullyDefined and all defs of reg or an overlapping register are dead, or
- Reg is completely dead because "defined" by a clobber.

◆ Defined
| bool llvm::MachineOperandIteratorBase::PhysRegInfo::Defined |
Reg or one of its aliases is defined.
The definition may only cover parts of the register.

◆ FullyDefined
| bool llvm::MachineOperandIteratorBase::PhysRegInfo::FullyDefined |
Reg or a super-register is defined.
The definition covers the full register.

Referenced by llvm::MachineOperandIteratorBase::analyzePhysReg(), and llvm::MachineBasicBlock::computeRegisterLiveness().
◆ FullyRead
| bool llvm::MachineOperandIteratorBase::PhysRegInfo::FullyRead |
Reg or a super-register is read. The full register is read.

◆ Killed
| bool llvm::MachineOperandIteratorBase::PhysRegInfo::Killed |
There is a use operand of reg or a super-register with kill flag set.
Definition at line 196 of file MachineInstrBundle.h.
Referenced by llvm::MachineOperandIteratorBase::analyzePhysReg(), and llvm::MachineBasicBlock::computeRegisterLiveness().
◆ PartialDeadDef
| bool llvm::MachineOperandIteratorBase::PhysRegInfo::PartialDeadDef |
Reg is Defined and all defs of reg or an overlapping register are dead.
Definition at line 193 of file MachineInstrBundle.h.

◆ Read
| bool llvm::MachineOperandIteratorBase::PhysRegInfo::Read |
Reg or one of its aliases is read.
The register may only be read partially.
