[PATCH] D154205: [MachineLICM] Handle subloops

[Benjamin Kramer via Phabricator via llvm-commits]

bkramer added inline comments.


================
Comment at: llvm/lib/CodeGen/MachineLICM.cpp:801
+        // pressure because we have already visited inner loop's preheader.
         UpdateRegPressure(&MI);
+      }
----------------
When MI is hoisted the pointer is no longer valid. I'm seeing use after frees with asan after this change, so reverted in 3454cf6
