Constructor Detail

TripsPGenerator

public TripsPGenerator(CallGraph cg,
                       Machine machine,
                       int features)

Parameters:

cg - is the call graph to be transformed

machine - specifies machine details

features - controls the instructions generated

Method Detail

generate

public void generate()

Generate the machine instructions for each routine in the call graph.

Overrides:

generate in class Generator

generateScribble

public void generateScribble()

Generate the machine instructions for a CFG.

Overrides:

generateScribble in class Trips2Generator

addPassThroughItem

protected void addPassThroughItem(java.lang.String item)

Add a string which should be passed through to the TIL unchanged.

getPassThroughItems

protected Vector<java.lang.String> getPassThroughItems()

Return the list of strings which should be passed through to the TIL. Each string will be terminated by an end-of-line.
