[PATCH] D62327: [X86][CodeGen][NFC] Delay `combineIncDecVector()` from DAGCombine to X86DAGToDAGISel

[Craig Topper via Phabricator via llvm-commits]

craig.topper added inline comments.


================
Comment at: lib/Target/X86/X86ISelDAGToDAG.cpp:3449
+  APInt SplatVal;
+  if (!X86::isConstantSplat(OneVec, SplatVal) || !SplatVal.isOneValue())
+    return false;
----------------
What happens to the constant pool value we already allocated. Does something recognize that is unused and not emit to the final assembly?
