...nique compared to func/module passes in that they could destroy the loop they worked on. And there might be no loop to print after that (btw, there is a known bug in new pass manager where it tries to print deleted loop in this situation - nothing good happens!). In your case loop unroll can fully uroll the loop, essentially removing the Loop. If you have suggestions on how to improve behavior in such cases I would be happy to discuss this further. regards, Fedor 8 нояб. 2018 г. 12:38 пользователь "Markus Lavin via llvm-dev" <llvm-dev at lists.llvm.org<mailto:llvm-dev at lists.l...

Hi, I recently worked on an issue where I realized that -print-after-all does not cover all passes run by the pass manager. E.g. it seems that loop passes are not fully covered and I could find that loop transformations showed up in the dump of the next non-loop pass (which happened to be 'Combine redundant instructions' and that was rather confusing). Specifying both -print-before-all
