Field Detail

mergedInitializers

private Map<ValuePhiNode,ValueNode> mergedInitializers

mergedInitializers. When an inside fragment's (loop)ends are merged to create a unique exit point, some phis must be created : they phis together all the back-values of the loop-phis These can then be used to update the loop-phis' forward edge value ('initializer') in the peeling case. In the unrolling case they will be used as the value that replace the loop-phis of the duplicated inside fragment

dataFixBefore

private final Graph.DuplicationReplacement dataFixBefore
