Method Detail

getName

public String getName()
Specified by:
getName in class CompilerPhase
Returns:
a String which is the name of the phase.

printingEnabled

public boolean printingEnabled(OptOptions options,
                               boolean before)
Description copied from class: CompilerPhase
Returns true if the phase wants the IR dumped before and/or after it runs. By default, printing is not enabled. Subclasses should override this method if they want to provide IR dumping.

Overrides:
printingEnabled in class CompilerPhase
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.

newExecution

public CompilerPhase newExecution(IR ir)
Description copied from class: CompilerPhase
This method is called immediately before performPhase. Phases that do not need to create a new instance for each execution may override this method to return this, but this must be done carefully! Classes that don't override this method need to override getClassConstructor.

Overrides:
newExecution in class CompilerPhase
Parameters:
ir - the IR that is about to be passed to performPhase
Returns:
an opt compiler phase on which performPhase may be invoked.

perform

public void perform(IR ir)
Description copied from class: CompilerPhase
This is the method that actually does the work of the phase.

Specified by:
perform in class CompilerPhase
Parameters:
ir - the IR on which to apply the phase
