[PATCH] D60762: [SelectionDAG] Legalize vaargs that require vector splitting

[Eli Friedman via Phabricator via llvm-commits]

================
Comment at: llvm/lib/CodeGen/SelectionDAG/LegalizeVectorTypes.cpp:1860
+  if (DAG.getDataLayout().isBigEndian())
+    std::swap(Lo, Hi);
+
----------------
This probably doesn't match how the vector will actually be passed on a big-endian target.  Endianness doesn't affect the ordering of the elements of a vector in LLVM.  (See also http://llvm.org/docs/BigEndianNEON.html .)
