[PATCH] D75400: [LICM] Allow freeze to hoist out of a loop

[Roman Lebedev via Phabricator via llvm-commits]

lebedev.ri added inline comments.


================
Comment at: llvm/lib/Transforms/Scalar/LICM.cpp:1235-1237
+    // Freeze instruction cannot be sunk into a loop because it may yield a
+    // different value for each iteration after sinking.
+    return !Flags->IsSink;
----------------
Should there be a standalone test for this?
