Class EnqueueToInitPath

java.lang.Object
  at.dms.kjc.sir.lowering.EnqueueToInitPath

public class EnqueueToInitPath
extends Object

Create initPath() functions for feedback loops that don't have them. Looks for feedback loops that don't have any initPath() function. If so, searches the init function for enqueue statements, and uses those to build an appropriate initPath() function. This pass must be run after constant propagation and loop unrolling, and assumes that enqueue statements are outside of any control flow.
