getMaxConstantDisplacement

public long getMaxConstantDisplacement()

Description copied from class: AddressNode

Constant that is the maximum displacement from the base and index for this address. This value is used to determine whether using the access as an implicit null check on the base is valid.

Specified by:

getMaxConstantDisplacement in class AddressNode

Returns:

the maximum distance in bytes from the base that this address can be

getAddressingMode

public AArch64Address.AddressingMode getAddressingMode()
