Constraints

uint16_t llvm::MCOperandInfo::Constraints

Operand constraints (see OperandConstraint enum).

Flags

uint8_t llvm::MCOperandInfo::Flags

These are flags from the MCOI::OperandFlags enum.

OperandType

uint8_t llvm::MCOperandInfo::OperandType

Information about the type of the operand.

RegClass

int16_t llvm::MCOperandInfo::RegClass

This specifies the register class enumeration of the operand if the operand is a register.

If LookupRegClassByHwMode is set, then this is an index into a table in TargetInstrInfo or MCInstrInfo which contains the real register class ID.
