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.
