Method Detail

getLabel

public java.lang.String getLabel()

Description copied from class: CompilerPass

What is the user-friendly name of this compiler pass

Specified by:

getLabel in class CompilerPass

getDependencies

public java.util.List<java.lang.Class<? extends CompilerPass>> getDependencies()

Overrides:

getDependencies in class CompilerPass

execute

public java.lang.Object execute(IRScope scope,
                                java.lang.Object... data)

Description copied from class: CompilerPass

Meat of an individual pass. run will call this after dependency resolution.

Specified by:

execute in class CompilerPass

Parameters:

scope - is the scope to run this pass on

data - is the data supplied to this pass to use to execute the pass

invalidate

public void invalidate(IRScope scope)

Description copied from class: CompilerPass

The data that this pass is responsible for will get invalidated so that if this pass is then execute()d it will generate new pass data. Note that some data will destructively manipulate dependent compiler pass data. In that case, the pass may wipe more than just it's data. In that case an execute() should still rebuild everything fine because all compiler passes list their dependencies.

Specified by:

invalidate in class CompilerPass

Parameters:

scope - is where the pass stores its data.
