Constructor Detail

MIR_CacheOp

public MIR_CacheOp()

Method Detail

conforms

public static boolean conforms(Instruction i)

InstructionFormat identification method for MIR_CacheOp.

Parameters:

i - an instruction

Returns:

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

conforms

public static boolean conforms(Operator o)

InstructionFormat identification method for MIR_CacheOp.

Parameters:

o - an instruction

Returns:

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

getAddress

public static RegisterOperand getAddress(Instruction i)

Get the operand called Address 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 Address

getClearAddress

public static RegisterOperand getClearAddress(Instruction i)

Get the operand called Address 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 Address

setAddress

public static void setAddress(Instruction i,
                              RegisterOperand Address)

Set the operand called Address 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

Address - the operand to store

indexOfAddress

public static int indexOfAddress(Instruction i)

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

Parameters:

i - the instruction to access.

Returns:

the index of the operand called Address in the argument instruction

hasAddress

public static boolean hasAddress(Instruction i)

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

Parameters:

i - the instruction to access.

Returns:

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

getOffset

public static RegisterOperand getOffset(Instruction i)

Get the operand called Offset 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 Offset

getClearOffset

public static RegisterOperand getClearOffset(Instruction i)

Get the operand called Offset 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 Offset

setOffset

public static void setOffset(Instruction i,
                             RegisterOperand Offset)

Set the operand called Offset 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

Offset - the operand to store

indexOfOffset

public static int indexOfOffset(Instruction i)

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

Parameters:

i - the instruction to access.

Returns:

the index of the operand called Offset in the argument instruction

hasOffset

public static boolean hasOffset(Instruction i)

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

Parameters:

i - the instruction to access.

Returns:

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

create

public static Instruction create(Operator o,
                                 RegisterOperand Address,
                                 RegisterOperand Offset)

Create an instruction of the MIR_CacheOp instruction format.

Parameters:

o - the instruction's operator

Address - the instruction's Address operand

Offset - the instruction's Offset operand

Returns:
