...ched unless the first branch condition was true. This means that the condition of the branch in for.cond.cleanup3 will always be true. As such, it is possible to eliminate this branch, making it unconditional. Is there an LLVM pass that is able to perform such transformation?

...om S0 to S1. Is this the expected behavior of DependenceInfo or Is it a known problem? If it is the expected behavior, is there a way to check if the dependence you are getting back is a correct one or not? Does anyone have any ideas about possible workarounds or solutions?

...ass manager because I need different copies of the same analysis to be valid at the same time, for different functions in the module (my understanding was that the new pass manager can do that whereas the legacy pass manager would only keep the last instance that was invoked).

...exit condition. I am wondering if there are any passes or data structures that would be able to help me accomplish what I am trying to do that I might be missing? Or does the community have any other ideas as to how I should approach this issue? Any input is much appreciated.

...and was wondering if there are attributes that specify this behavior (I know there is the ‘noread’ attribute but wasn’t sure if there’s something similar for writes)? Also, how can I tell clang to generate those attributes at the function declaration? Any information would be helpful.
