Constructor Detail

ArbitraryOperandsInstruction

public ArbitraryOperandsInstruction(int opcode,
                            Object[] operands)

Construct an ArbitraryOperandsInstruction.

Parameters:

opcode - - the opcode. Passed to superclass constructor.

operands - - the operands. May be null.

ArbitraryOperandsInstruction

public ArbitraryOperandsInstruction(int opcode,
                            ArbitraryOperandsInstruction original)

"Copy" construct an ArbitraryOperandsInstruction with a new opcode.

Parameters:

opcode - - the opcode.

original - - the original ArbitraryOperandsInstruction whose operands are to be incorporated into the new instruction.

Method Detail

toString

public String toString()

Overrides:

toString in class Instruction

Returns:

a string representation of the opcode.

getOperand

public Object getOperand(int index)

Fetch an operand.

Overrides:

getOperand in class Instruction

Parameters:

index - - the index of the operand of interest.

Returns:

the operand at the specified index.

getOperandCount

public int getOperandCount()

Overrides:

getOperandCount in class Instruction

Returns:

the instruction's operand count; if the operands are not yet present, then return 0.

setOperands

public void setOperands(Object[] operands)

Set this instruction's operands in a fixup pass.

Overrides:

setOperands in class Instruction

Parameters:

operands - - the instruction's operands.

setTempRegisters

public void setTempRegisters(Object[] tempregs)

Set the temporary register operands of a hasnext2 instruction.

Overrides:

setTempRegisters in class Instruction
