Constructor Detail

TripsLabel

public TripsLabel(boolean referenced,
                  RoutineDecl routine)

TripsLabel

public TripsLabel(RoutineDecl routine)

Create a label.

Parameters:

routine - specifies the routine containing this label

Method Detail

getRoutine

public RoutineDecl getRoutine()

getLabelString

public java.lang.String getLabelString()

Return the String representing the label.

getLoopNumber

public int getLoopNumber()

Return the loop number of the instruction. This is Trips specific. For all other backends, it returns 0.

Overrides:

getLoopNumber in class Instruction

setLoopNumber

protected void setLoopNumber(int loopNumber)

Set the loop number of the instruction. This is Trips specific. For all other backends, it does nothing.

Overrides:

setLoopNumber in class Instruction
