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

getShortLabel

public java.lang.String getShortLabel()

Description copied from class: CompilerPass

Shorter label

Overrides:

getShortLabel in class CompilerPass

eliminateLocalVars

public void eliminateLocalVars(IRScope s)

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 boolean 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 executed 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.

Overrides:

invalidate in class CompilerPass

Parameters:

scope - is where the pass stores its data.
