Constructor Detail

MIR_Test

public MIR_Test()
Method Detail

conforms

public static boolean conforms(Instruction i)
InstructionFormat identification method for MIR_Test.

Parameters:
i - an instruction
Returns:
true if the InstructionFormat of the argument instruction is MIR_Test or false if it is not.

conforms

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

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

getVal1

public static Operand getVal1(Instruction i)
Get the operand called Val1 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 Val1

getClearVal1

public static Operand getClearVal1(Instruction i)
Get the operand called Val1 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 Val1

setVal1

public static void setVal1(Instruction i,
                           Operand Val1)
Set the operand called Val1 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
Val1 - the operand to store

indexOfVal1

public static int indexOfVal1(Instruction i)
Return the index of the operand called Val1 in the argument instruction.

Parameters:
i - the instruction to access.
Returns:
the index of the operand called Val1 in the argument instruction

hasVal1

public static boolean hasVal1(Instruction i)
Does the argument instruction have a non-null operand named Val1?

Parameters:
i - the instruction to access.
Returns:
true if the instruction has an non-null operand named Val1 or false if it does not.

getVal2

public static Operand getVal2(Instruction i)
Get the operand called Val2 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 Val2

getClearVal2

public static Operand getClearVal2(Instruction i)
Get the operand called Val2 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 Val2

setVal2

public static void setVal2(Instruction i,
                           Operand Val2)
Set the operand called Val2 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
Val2 - the operand to store

indexOfVal2

public static int indexOfVal2(Instruction i)
Return the index of the operand called Val2 in the argument instruction.

Parameters:
i - the instruction to access.
Returns:
the index of the operand called Val2 in the argument instruction

hasVal2

public static boolean hasVal2(Instruction i)
Does the argument instruction have a non-null operand named Val2?

Parameters:
i - the instruction to access.
Returns:
true if the instruction has an non-null operand named Val2 or false if it does not.

create

public static Instruction create(Operator o,
                                 Operand Val1,
                                 Operand Val2)
Create an instruction of the MIR_Test instruction format.

Parameters:
o - the instruction's operator
Val1 - the instruction's Val1 operand
Val2 - the instruction's Val2 operand
Returns:
the newly created MIR_Test instruction

mutate

public static Instruction mutate(Instruction i,
                                 Operator o,
                                 Operand Val1,
                                 Operand Val2)
Mutate the argument instruction into an instruction of the MIR_Test instruction format having the specified operator and operands.

Parameters:
i - the instruction to mutate
o - the instruction's operator
Val1 - the instruction's Val1 operand
