Method Detail

shouldPerform

public final 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

newExecution

public CompilerPhase newExecution(IR ir)

Return this instance of this phase. This phase contains no per-compilation instance fields.

Overrides:: newExecution in class CompilerPhase

Parameters:: ir - not used
Returns:: this

getName

public final String getName()

Specified by:: getName in class CompilerPhase

Returns:: a String which is the name of the phase.

perform

public final void perform(IR ir)

create the stack manager

Specified by:: perform in class CompilerPhase

Parameters:: ir - the IR on which to apply the phase
