Constructor Detail

MIR_Lea

public MIR_Lea()
Method Detail

conforms

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

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

conforms

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

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

getResult

public static RegisterOperand getResult(Instruction i)
Get the operand called Result 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 Result

getClearResult

public static RegisterOperand getClearResult(Instruction i)
Get the operand called Result 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 Result

setResult

public static void setResult(Instruction i,
                             RegisterOperand Result)
Set the operand called Result 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
Result - the operand to store

indexOfResult

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

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

hasResult

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

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

getValue

public static MemoryOperand getValue(Instruction i)
Get the operand called Value 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 Value

getClearValue

public static MemoryOperand getClearValue(Instruction i)
Get the operand called Value 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 Value

setValue

public static void setValue(Instruction i,
                            MemoryOperand Value)
Set the operand called Value 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
Value - the operand to store

indexOfValue

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

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

hasValue

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

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

create

public static Instruction create(Operator o,
                                 RegisterOperand Result,
                                 MemoryOperand Value)
Create an instruction of the MIR_Lea instruction format.

Parameters:
o - the instruction's operator
Result - the instruction's Result operand
Value - the instruction's Value operand
Returns:
the newly created MIR_Lea instruction

mutate

public static Instruction mutate(Instruction i,
                                 Operator o,
                                 RegisterOperand Result,
                                 MemoryOperand Value)
Mutate the argument instruction into an instruction of the MIR_Lea instruction format having the specified operator and operands.

Parameters:
i - the instruction to mutate
o - the instruction's operator
Result - the instruction's Result operand
Value - the instruction's Value operand
Returns:
the mutated instruction
