...elation between loop predecessor blocks of the two loops if there is no dominance relation between their loop headers just like case three. The only thing I'm not pretty sure is that is there guarantee to exist dominance relation on their loop predecessor blocks. That is, either LPred dominates RPred or RPred dominate LPred?

Hi, I'm using the R library(car) to draw confidence/prediction ellipses in a scatterplot. >From what i understood the ellipse() function return an ellipse based parameters: shape, center, radius . If i read dataEllipse() function i can see how these parameters are calculated for a confidence ellipse. ibrary(car) a=c(12,12,4,5,63,63,23) b=c(13,15,7,10,73,83,43) v <-

Hi, Recently I got a crash when I tried to analysis a program with ScalarEvolution AliasAnalysis(SCEV-AA for short). It turns out to be a (possibly) incorrect assertion inside the CompareSCEVComplexity routine. The simplest solution would be just remove that assertion but I also found that the surrounding logics on calculating SCEV cost seems to be incorrect either. Thus I want to discuss with
