...uction PHINode *indv = NULL; indv = L->getCanonicalInductionVariable(); However, when I check indv is always set to NULL. Since the code has a canonical induction variable, I was expecting the endv to start pointing to the induction var phi node. Please let me what I'm missing here Thanks Malveeka -------------- next part -------------- An HTML attachment was scrubbed...

...liar with the llvm infrastructure and I am not sure if the above approach is even going to work. It'll be great if someone can suggest a better or more concrete way of doing the above transformation ? Is there already something similar in the source tree that can I look up for ideas ? Thanks!

Malveeka, You can use the LoopInfo analysis to find the induction variable. http://llvm.org/docs/doxygen/html/classllvm_1_1Loop.html#a72bbf45d2e00971f56bf8cfe4e1df01c Cheers, Nadav From: llvmdev-bounces at cs.uiuc.edu [mailto:llvmdev-bounces at cs.uiuc.edu] On Behalf Of Malveeka Tewari Sent: Thursday...

Hi, What does your LLVM IR look like. Are you sure the loop hasnt been optimized away?

...gs ? I am not sure if my pass should implement both runOnLoop and runOnFunction methods or not. I tried implementing a pass that subclasses both Function and Loop Pass, but that didn't seem to work. Any suggestions on the best way to implement such a pass will be extremely helpful. Thanks!
