clear

public static void clear()

Clean up data structures used in flattening. Only call after done flattening.

getTopLevelNodes

public static UnflatFilter[] getTopLevelNodes()

Returns list of all top level nodes.

flattenGraph

public static void flattenGraph(SIRStream graph,
                                LinearAnalyzer lfa,
                                HashMap[] execCounts)

Main entry point to FlattenGraph.

Parameters:

graph - The toplevel SIRStream for the graph

lfa - The LinearAnalyzer to use for linear representation

execCounts - Execution counts from scheduler

dumpGraph

public static void dumpGraph(String filename)

Prints out dotgraph representation of current flatgraph.

Parameters:

filename - Filename to store dotgraph into.
