[Eli Friedman via Phabricator via llvm-commits]

efriedma added inline comments.


================
Comment at: llvm/lib/Target/AArch64/AArch64ISelLowering.cpp:987
       if (isTypeLegal(VT)) {
+        setOperationAction(ISD::CONCAT_VECTORS, VT, Custom);
         setOperationAction(ISD::INSERT_SUBVECTOR, VT, Custom);
----------------
Thinking about it a little more, we probably only want to mark CONCAT_VECTORS "Custom" for vectors with four or more elements.  It's never legal if the result is a two-element vector.
