[PATCH] D47408: [PM/LoopUnswitch] When using the new SimpleLoopUnswitch pass, schedule loop-cleanup passes at the beginning of the loop pass pipeline, and re-enqueue loops after even trivial unswitching.

dmgreen added inline comments.


================
Comment at: llvm/lib/Transforms/IPO/PassManagerBuilder.cpp:340
+  // Begin the loop pass pipeline.
   // Rotate Loop - disable header duplication at -Oz
+  if (EnableSimpleLoopUnswitch) {
----------------
Should this comment be moved down next to the loop rotate pass?
