Method Summary

DDGraph	analyzeLoopsForDependence(Loop loop) Analyze this loop and all inner loops to build a dependence graph for the loop nest with this loop as the outermost loop
DDGraph	getDDGraph(boolean summarize, Loop loop) Deprecated. This routine must no longer be used to get access to data dependence information Instead, obtain a copy of the dependence graph from Program object and use DDGraph API for details related to dependence information

public java.lang.String getPassName()

Specified by:

getPassName in class AnalysisPass

analyzeLoopsForDependence

public DDGraph analyzeLoopsForDependence(Loop loop)

Analyze this loop and all inner loops to build a dependence graph for the loop nest with this loop as the outermost loop

getDDGraph

public DDGraph getDDGraph(boolean summarize,
                          Loop loop)

Deprecated. This routine must no longer be used to get access to data dependence information Instead, obtain a copy of the dependence graph from Program object and use DDGraph API for details related to dependence information

Performs data-dependence analysis on the nest defined by loop and returns the dependence graph summarize = Direction Vectors summarized or not

Returns:

DDGraph - dependence graph for nest null if loop nest is not eligible for dependence analysis
