MIR_Return

public MIR_Return()

Method Detail

conforms

public static boolean conforms(Instruction i)

InstructionFormat identification method for MIR_Return.

Parameters:

i - an instruction

Returns:

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

conforms

public static boolean conforms(Operator o)

InstructionFormat identification method for MIR_Return.

Parameters:

o - an instruction

Returns:

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

getVal

public static RegisterOperand getVal(Instruction i)

Get the operand called Val 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 Val

getClearVal

public static RegisterOperand getClearVal(Instruction i)

Get the operand called Val 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 Val

setVal

public static void setVal(Instruction i,
                          RegisterOperand Val)

Set the operand called Val 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

Val - the operand to store

indexOfVal

public static int indexOfVal(Instruction i)

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

Parameters:

i - the instruction to access.

Returns:

the index of the operand called Val in the argument instruction

hasVal

public static boolean hasVal(Instruction i)

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

Parameters:

i - the instruction to access.

Returns:

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

getVal2

public static RegisterOperand 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 RegisterOperand 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,
                           RegisterOperand 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,
                                 RegisterOperand Val,
                                 RegisterOperand Val2)

Create an instruction of the MIR_Return instruction format.
