                       Operand argument)
Method Detail

toString

public java.lang.String toString()
Overrides:
toString in class Instr

getArg

public Operand getArg()

getOperands

public Operand[] getOperands()
Specified by:
getOperands in class Instr

simplifyOperands

public void simplifyOperands(java.util.Map<Operand,Operand> valueMap)
Description copied from class: Instr
This method takes as input a map of operands to their values, and outputs If the value map provides a value for any of the instruction's operands this method is expected to replace the original operands with the simplified values. It is not required that it do so -- code correctness is not compromised by failure to simplify
