[PATCH] D98958: [NewPM] Disable non-trivial loop-unswitch on targets with divergence

[Stanislav Mekhanoshin via Phabricator via llvm-commits]

rampitec added inline comments.


================
Comment at: llvm/lib/Transforms/Scalar/SimpleLoopUnswitch.cpp:2907
+  // unswitching, which is useful for testing and debugging.
+  if ((!NonTrivial || TTI.hasBranchDivergence()) && !EnableNonTrivialUnswitch)
     return false;
----------------
Is this a correct condition? Double negative "!NonTrivial" = Trivial, right? Are we not doing trivial loop unswitching?
