public LoadElimination.LoadEliminationPreparation(int round)

Cosntructor

Method Detail

getClassConstructor

public Constructor<CompilerPhase> getClassConstructor()

Get a constructor object for this compiler phase

Overrides:: getClassConstructor in class CompilerPhase

Returns:: compiler phase constructor

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

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)
