[PATCH] D110620: [SCEV] Infer ranges for SCC consisting of cycled Phis

[Max Kazantsev via Phabricator via llvm-commits]

mkazantsev added a comment.

Actually the definition of "almost addrec" doesn't even cover the motivation for this patch, where we have 2 phis from same block that just swap values. I don't think we can have any good framing here.
