Structure Arm64Instruction.​Operand 

public struct Operand: InstructionOperand

Operand for Arm64 instructions.

The operand's value can be accessed by the value property, or by a property corresponding to the operand's type:

  • register for reg operands.

  • systemRegister for regMrs or regMsr operands, or sys operands of mrs or msr instructions.

  • immediateValue for imm or cimm operands.

  • doubleValue for fp operands.

  • memory for mem operands.

  • pState for pstate operands.

  • ic, dc, at or tlbi for sys operands of those instructions.

  • prefetch for prefetch operands

  • barrier for barrier operands
