conforms

public static boolean conforms(Operator o)
InstructionFormat identification method for InstrumentedCounter.

Parameters:
o - an instruction
Returns:
true if the InstructionFormat of the argument operator is InstrumentedCounter or false if it is not.

getData

public static IntConstantOperand getData(Instruction i)
Get the operand called Data from the argument instruction. Note that the returned operand will still point to its containing instruction.

Parameters:
i - the instruction to fetch the operand from
Returns:
the operand called Data

getClearData

public static IntConstantOperand getClearData(Instruction i)
Get the operand called Data from the argument instruction clearing its instruction pointer. The returned operand will not point to any containing instruction.

Parameters:
i - the instruction to fetch the operand from
Returns:
the operand called Data

setData

public static void setData(Instruction i,
                           IntConstantOperand Data)

Parameters:
i - the instruction in which to store the operand
Data - the operand to store

indexOfData

public static int indexOfData(Instruction i)
Return the index of the operand called Data in the argument instruction.

Parameters:
i - the instruction to access.

the index of the operand called Data in the argument instruction

hasData

public static boolean hasData(Instruction i)
Does the argument instruction have a non-null operand named Data?

Parameters:
i - the instruction to access.
Returns:
true if the instruction has an non-null operand named Data or false if it does not.

getIndex

public static IntConstantOperand getIndex(Instruction i)
Get the operand called Index from the argument instruction. Note that the returned operand will still point to its containing instruction.

Parameters:
i - the instruction to fetch the operand from
Returns:
the operand called Index

getClearIndex

public static IntConstantOperand getClearIndex(Instruction i)
