Method Detail

shouldPerform

public boolean shouldPerform(OptOptions options)

Description copied from class: CompilerPhase

This method determines if the phase should be run, based on the Options object it is passed. By default, phases are always performed. Subclasses should override this method if they only want to be performed conditionally.

Overrides:

shouldPerform in class CompilerPhase

Parameters:

options - the compiler options for the compilation

Returns:

true if the phase should be performed

getName

public String getName()

Returns "Dominator Tree"

Specified by:

getName in class CompilerPhase

Returns:

"Dominator Tree"

printingEnabled

public boolean printingEnabled(OptOptions options,
                               boolean before)

Should the IR be printed before and/or after this phase?

Overrides:

printingEnabled in class CompilerPhase

Parameters:

options - controlling compiler options

before - query control

Returns:

false

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
