Anna, since Daniel doesn't yet have commit access would you mind landing this?  I would do it myself, but can't commit the time to watch for any problems after commit.



================
Comment at: lib/Transforms/Scalar/LoopIdiomRecognize.cpp:362
+    return LegalStoreKind::None;
+  // We only want simple or unordered-atomic stores (note: unordered => simple)
+  if (!SI->isUnordered())
----------------
I don't understand the note?  Maybe just remove
