Method Detail

getName

public String getName()

Specified by:

getName in class CompilerPhase

Returns:

a String which is the name of the phase.

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.

expandSysCall

private void expandSysCall(Instruction s,
                           IR ir)

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
