Constructor Detail

MIR_UnaryAcc

public MIR_UnaryAcc()
Method Detail

conforms

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

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

conforms

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

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

getResult

public static Operand 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 Operand 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,
                             Operand 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.

create

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

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

mutate

public static Instruction mutate(Instruction i,
                                 Operator o,
                                 Operand Result)
Mutate the argument instruction into an instruction of the MIR_UnaryAcc 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
Returns:
the mutated instruction
