static void	removeObsoleteProxies(StructuredGraph graph, CoreProviders context, CanonicalizerPhase canonicalizer) Remove loop proxies that became obsolete over time, i.e., they proxy a value that already flowed out of a loop and dominates the loop now.

Method Detail

removeObsoleteProxies

public static void removeObsoleteProxies(StructuredGraph graph,
                                         CoreProviders context,
                                         CanonicalizerPhase canonicalizer)

Remove loop proxies that became obsolete over time, i.e., they proxy a value that already flowed out of a loop and dominates the loop now.

Parameters:

canonicalizer - must not be null, will be applied incrementally to nodes whose inputs changed

removeObsoleteProxiesForLoop

public static void removeObsoleteProxiesForLoop(LoopEx loop)

Remove obsolete proxies from one loop only. Unlike LoopUtility.removeObsoleteProxies(StructuredGraph, CoreProviders, CanonicalizerPhase), this does not apply canonicalization.
