Constructor Detail

MIR_UnaryNoRes

public MIR_UnaryNoRes()
Method Detail

conforms

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

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

conforms

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

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

getVal

public static Operand 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 Operand 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,
                          Operand 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.

create

public static Instruction create(Operator o,
                                 Operand Val)
Create an instruction of the MIR_UnaryNoRes instruction format.

Parameters:
o - the instruction's operator
Val - the instruction's Val operand
Returns:
the newly created MIR_UnaryNoRes instruction

mutate

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

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