Class RemoveDynamicRates

java.lang.Object
  at.dms.kjc.sir.EmptyStreamVisitor
      at.dms.kjc.sir.lowering.RemoveDynamicRates

All Implemented Interfaces:

StreamVisitor

public class RemoveDynamicRates
extends EmptyStreamVisitor

NOTE: This class is deprecated in favor of SIRDynamicRateManager. (However, this class still might be useful if we want to replace all dynamic rates with something in the IR.) This class performs an UNSAFE TRANSFORMATION in which all dynamic rates are replaced with the constant 1. This is an easy way to push dynamic rates through backends such as the cluster backend, where the rate information is not used for anything critical but needs to be resolved to some constant.
