Interface IInstructionOperandCMA

All Superinterfaces:

IInstructionOperand, IInstructionOperandGeneric, IInstructionOperandRegisterBased, IInstructionOperandSized

public interface IInstructionOperandCMA
extends IInstructionOperandGeneric

Operands performing Complex Memory Access (CMA). Such operands access memory via a combination of registers and displacement values. Specifically, memory references can be made using a base register, a scaled-index, and a displacement: [baseRegister + scale*indexRegister + displacement]

Note that simple uses of this operand could also be represented using simpler IInstructionOperandGeneric objects, eg for (scaled-index=None, disp=0) or (base=None, scaled-index=None).

Method Details

getMemoryBaseRegister

long getMemoryBaseRegister()

Get the base register identifier.

Returns:

the identifier, -1 should be used to denote no register

getMemoryScale

int getMemoryScale()

Get the scale used with the index register.

Returns:

the scale, 0 if there is no scaled-index

getMemoryIndexRegister

long getMemoryIndexRegister()

Get the index register identifier.

Returns:

the identifier, -1 should be used to denote no register

getMemoryDisplacement

long getMemoryDisplacement()

Get the memory displacement.

Returns:

the signed displacement, 0 if none
