Due to local packing, we may have chains of assignments to the same local. push null; store.r $r2; push null; store.r $r2; This transformer eliminates the redundant push/store instructions.

This method is called to perform the transformation itself. It is declared abstract; subclasses must implement this method by making it the entry point to their actual Body transformation.

Specified by:

internalTransform in class BodyTransformer

Parameters:

b - the body on which to apply the transformation

phaseName - the phasename for this transform; not typically used by implementations.

options - the actual computed options; a combination of default options and Scene specified options.
