Method Detail

shouldPerform

public boolean shouldPerform(OptOptions options)

Description copied from class: OptimizationPlanElement

Determine, possibly by consulting the passed options object, if this optimization plan element should be performed.

Overrides:: shouldPerform in class OptimizationPlanCompositeElement

Parameters:: options - The Options object for the current compilation.
Returns:: true if the plan element should be performed.

getName

public String getName()

Overrides:: getName in class OptimizationPlanCompositeElement

Returns:: a String which is the name of the phase.

printingEnabled

public boolean printingEnabled(OptOptions options,
                               boolean before)

Description copied from class: OptimizationPlanCompositeElement

Returns true if the phase wants the IR dumped before and/or after it runs. By default, printing is not enabled. Subclasses should overide this method if they want to provide IR dumping.

Overrides:: printingEnabled in class OptimizationPlanCompositeElement

Parameters:: options - the compiler options for the compilation; before - true when invoked before perform, false otherwise.
Returns:: true if the IR should be printed, false otherwise.
