[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added inline comments.


================
Comment at: llvm/lib/Target/X86/X86ISelLowering.h:594
+      // extract_vector_elt, store.
+      VEXTRACT_STORE,
+
----------------
If we used MOVSD (f64 store) could we avoid needing this NodeType?
