Class FuseAll

java.lang.Object
  at.dms.kjc.sir.lowering.fusion.FuseAll

All Implemented Interfaces:

StreamVisitor

public class FuseAll
extends Object
implements StreamVisitor

This class fuses all the pipelines that it can in a stream graph. We need to fuse all the children of the current stream we're visiting (rather than the stream itself) so that the iterators don't get confused.

Method Detail

fuse

public static SIRPipeline fuse(SIRStream str,
                               boolean strict)

Fuse everything we can in . Returns new fused segment, which is also mutated in the stream graph. If 'strict' is true, then prints an error message and exits if it can't succeed in fusing down to 1 filter; otherwise it just does its best (i.e., with respect to feedbackloops).
