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

verify

public void verify(IR ir)

Description copied from class: CompilerPhase

Verify the IR. Written as a non-final virtual method to allow late stages in the compilation pipeline (eg ConvertMIR2MC) to skip verification.

Overrides:

verify in class CompilerPhase

Parameters:

ir - the IR to verify
