GuardResultCarrier

public GuardResultCarrier()
Method Detail

conforms

public static boolean conforms(Instruction i)
Does the instruction belong to an instruction format that has an operand called GuardResult?

Parameters:
i - the instruction to test
Returns:
true if the instruction's instruction format has an operand called GuardResult and false if it does not.

conforms

public static boolean conforms(Operator o)
Does the operator belong to an instruction format that has an operand called GuardResult?

Parameters:
o - the operator to test
Returns:
true if the instruction's instruction format has an operand called GuardResult and false if it does not.

getGuardResult

public static RegisterOperand getGuardResult(Instruction i)
Get the operand called GuardResult 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 GuardResult

getClearGuardResult

public static RegisterOperand getClearGuardResult(Instruction i)
Get the operand called GuardResult 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 GuardResult

setGuardResult

public static void setGuardResult(Instruction i,
                                  RegisterOperand op)
Set the operand called GuardResult 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
op - the operand to store

indexOfGuardResult

public static int indexOfGuardResult(Instruction i)
Return the index of the operand called GuardResult in the argument instruction.

Parameters:
i - the instruction to access.
Returns:
the index of the operand called GuardResult in the argument instruction

hasGuardResult

public static boolean hasGuardResult(Instruction i)
Does the argument instruction have a non-null operand named GuardResult?

Parameters:
i - the instruction to access.
Returns:
true if the instruction has an non-null operand named GuardResult or false if it does not.
