Parameters:

o - an instruction

Returns:

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

getResult

public static RegisterOperand 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 RegisterOperand 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,
                             RegisterOperand Result)

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.

getValue1

public static RegisterOperand getValue1(Instruction i)

Get the operand called Value1 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 Value1

getClearValue1

public static RegisterOperand getClearValue1(Instruction i)

Get the operand called Value1 from the argument instruction clearing its instruction pointer. The returned operand will not point to any containing instruction.

Parameters:
