MIR_RDTSC

public MIR_RDTSC()

Method Detail

conforms

public static boolean conforms(Instruction i)

InstructionFormat identification method for MIR_RDTSC.

Parameters:

i - an instruction

Returns:

true if the InstructionFormat of the argument instruction is MIR_RDTSC or false if it is not.

conforms

public static boolean conforms(Operator o)

InstructionFormat identification method for MIR_RDTSC.

Parameters:

o - an instruction

Returns:

true if the InstructionFormat of the argument operator is MIR_RDTSC or false if it is not.

getDest1

public static RegisterOperand getDest1(Instruction i)

Get the operand called Dest1 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 Dest1

getClearDest1

public static RegisterOperand getClearDest1(Instruction i)

Get the operand called Dest1 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 Dest1

setDest1

public static void setDest1(Instruction i,
                            RegisterOperand Dest1)

Set the operand called Dest1 in the argument instruction to the argument operand. The operand will now point to the argument instruction as its containing instruction.

Parameters:

i - the instruction in which to store the operand

Dest1 - the operand to store

indexOfDest1

public static int indexOfDest1(Instruction i)

Return the index of the operand called Dest1 in the argument instruction.

Parameters:

i - the instruction to access.

Returns:

the index of the operand called Dest1 in the argument instruction

hasDest1

public static boolean hasDest1(Instruction i)

Does the argument instruction have a non-null operand named Dest1?

Parameters:

i - the instruction to access.

Returns:

true if the instruction has an non-null operand named Dest1 or false if it does not.

getDest2

public static RegisterOperand getDest2(Instruction i)

Get the operand called Dest2 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 Dest2

getClearDest2

public static RegisterOperand getClearDest2(Instruction i)

Get the operand called Dest2 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 Dest2

setDest2

public static void setDest2(Instruction i,
                            RegisterOperand Dest2)

Set the operand called Dest2 in the argument instruction to the argument operand. The operand will now point to the argument instruction as its containing instruction.

Parameters:

i - the instruction in which to store the operand

Dest2 - the operand to store

indexOfDest2

public static int indexOfDest2(Instruction i)

Return the index of the operand called Dest2 in the argument instruction.

Parameters:

hasDest2

public static boolean hasDest2(Instruction i)

Does the argument instruction have a non-null operand named Dest2?

Parameters:
