[PATCH] D111493: [IVUsers] Check for preheader instead of loop simplify form

[Nikita Popov via Phabricator via llvm-commits]

nikic added inline comments.


================
Comment at: llvm/lib/Analysis/IVUsers.cpp:107
       // If the domtree walk reaches a loop with no preheader, return false.
-      if (!DomLoop->isLoopSimplifyForm())
+      if (!DomLoop->getLoopPreheader())
         return false;
----------------
This is the only functional change in the patch, the rest is just renames.
