Structure `ArmInstruction.Operand`

public struct Operand: InstructionOperand

Operand for Arm 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 sysreg operands.
immediateValue for imm, pimm or cimm operands.
doubleValue for fp operands.
memory for mem operands.
setend for setend operands (only used for setend instruction).

Member Of

Nested Types

ArmInstruction.Operand.Shift: Instruction operand shift.
ArmInstruction.Operand.Memory: Operand value referring to memory.

Conforms To

Properties

`type`

var type: ArmOp

Operand type.

`access`

var access: Access

Operand access mode.

`vectorIndex`

var vectorIndex: Int!

Vector Index for some vector operands.

nil if not applicable.

`shift`

var shift: Shift?

Operand shift.

nil if operand has no shift.

`subtracted`

var subtracted: Bool

In some instructions, an operand can be subtracted or added to the base register.

`neonLane`

var neonLane: Int!

Neon lane index for NEON instructions.

nil when not a NEON instruction.

`register`

var register: ArmReg!

Register value for reg operand.

nil when not an appropriate operand.

`systemRegister`

var systemRegister: ArmSysreg!

System register value for sysreg operand.

nil when not an appropriate operand.

`immediateValue`

var immediateValue: Int32!

Immediate value for C-IMM, P-IMM or IMM operand.

nil when not an appropriate operand.

`doubleValue`

var doubleValue: Double!

Floating point value for FP operand.

nil when not an appropriate operand.

`memory`

var memory: Memory!

Base/index/scale/disp value for memory operand.

nil when not an appropriate operand.

`setend`

var setend: ArmSetend!

Operand type for SETEND instruction.

nil when not an appropriate operand.

`value`

var value: ArmOperandValue

Operand value.

Return type depends on the operand type.
