[PATCH] D91363: [SVE][CodeGen] Extend isConstantSplatValue to support ISD::SPLAT_VECTOR

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added inline comments.


================
Comment at: llvm/lib/CodeGen/SelectionDAG/SelectionDAG.cpp:148
+      if (EltSize < SplatVal.getBitWidth())
+        SplatVal = SplatVal.trunc(EltSize);
+      return true;
----------------
Is there a truncOrSelf we can use?
