[PATCH] D90402: [LoopFlatten] Run it earlier, just before IndVarSimplify

[Dave Green via Phabricator via llvm-commits]

dmgreen added a comment.

OK yeah, they look like they are already in different loop managers on the old pass manager side.



================
Comment at: llvm/lib/Passes/PassBuilder.cpp:527
+  if (EnableLoopFlatten)
+    LPM2.addPass(LoopFlattenPass());
+
----------------
I think this one would be better put into a new LoopPassManager, LPM3, if flattening is enabled. I think that's how it's meant to work.
