Constructor Detail

MIR_ConvertDW2QW

public MIR_ConvertDW2QW()
Method Detail

conforms

public static boolean conforms(Instruction i)
InstructionFormat identification method for MIR_ConvertDW2QW.

Parameters:
i - an instruction
Returns:
true if the InstructionFormat of the argument instruction is MIR_ConvertDW2QW or false if it is not.

conforms

public static boolean conforms(Operator o)
InstructionFormat identification method for MIR_ConvertDW2QW.

Parameters:
o - an instruction
Returns:
true if the InstructionFormat of the argument operator is MIR_ConvertDW2QW or false if it is not.

getResult1

public static Operand getResult1(Instruction i)
Get the operand called Result1 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 Result1

getClearResult1

public static Operand getClearResult1(Instruction i)
Get the operand called Result1 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 Result1

setResult1

public static void setResult1(Instruction i,
                              Operand Result1)
Set the operand called Result1 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
Result1 - the operand to store

indexOfResult1

public static int indexOfResult1(Instruction i)
Return the index of the operand called Result1 in the argument instruction.

Parameters:
i - the instruction to access.
Returns:
the index of the operand called Result1 in the argument instruction

hasResult1

public static boolean hasResult1(Instruction i)
Does the argument instruction have a non-null operand named Result1?

Parameters:
i - the instruction to access.
Returns:
true if the instruction has an non-null operand named Result1 or false if it does not.

getResult2

public static Operand getResult2(Instruction i)
Get the operand called Result2 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 Result2

getClearResult2

public static Operand getClearResult2(Instruction i)
Get the operand called Result2 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 Result2

setResult2

public static void setResult2(Instruction i,
                              Operand Result2)
Set the operand called Result2 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
Result2 - the operand to store

indexOfResult2

public static int indexOfResult2(Instruction i)
Return the index of the operand called Result2 in the argument instruction.

Parameters:
i - the instruction to access.
Returns:
the index of the operand called Result2 in the argument instruction

hasResult2

public static boolean hasResult2(Instruction i)
Does the argument instruction have a non-null operand named Result2?

Parameters:
i - the instruction to access.
Returns:
true if the instruction has an non-null operand named Result2 or false if it does not.

create

public static Instruction create(Operator o,
                                 Operand Result1,
                                 Operand Result2)
Create an instruction of the MIR_ConvertDW2QW instruction format.

Parameters:
o - the instruction's operator
Result1 - the instruction's Result1 operand
Result2 - the instruction's Result2 operand
Returns:
the newly created MIR_ConvertDW2QW instruction

mutate

public static Instruction mutate(Instruction i,
                                 Operator o,
                                 Operand Result1,
                                 Operand Result2)
Mutate the argument instruction into an instruction of the MIR_ConvertDW2QW instruction format having the specified operator and operands.
