Constructor Summary

X86ImmediateOperand(Variable var)

X86ImmediateOperand(Variable var, boolean treatArrayAsConst)
Specifically intended for doing instructions like "mov $iC, %edx" where iC is begining of an array, and is ok to treat as a 4byte pointer constant

Method Summary

void	freeOperand() Frees any resources (registers) that have been allocated for the operand
int	getOperandSize() Returns the operand's byte size, should be either 1, 2, or 4
int	getOperandType() Returns the X86Operand type, must be one of X86Operand.OPERAND_TYPE_xxx
java.lang.String	toString()
