Dear All, Is the following patch to ScalarEvolution correct? It seems that without it, the enclosing for loop could skip over SCEVAddRecExpr's in the Ops[] array. -- John T. -------------- next part -------------- An embedded and charset-unspecified text was scrubbed...

I need to be able to detect a well-behaved loop. (i.e one where exp1 assigns a value to an int i, exp2 compares i with a loop constant, exp3 adjusts i by a loop constant, and the inner block has no assignments to i.) I need this because in Sun's Java VM garbage collection only takes place at safepoints, so a potentially unbounded loop must call safepoint() some time. However, safepoints are
