[PATCH] D57616: [DAGCombiner] Discard pointer info when combining extract_vector_elt of a vector load when the index isn't constant

[Eli Friedman via Phabricator via llvm-commits]

This is a little unfortunate, but looks correct.



================
Comment at: lib/CodeGen/SelectionDAG/DAGCombiner.cpp:15645
+    // access isn't in the default address space.
+    if (OriginalLoad->getPointerInfo().getAddrSpace() != 0)
+      return SDValue();
----------------
MachinePointerInfo has a constructor which takes an address-space (see https://reviews.llvm.org/rL319622 ).
