[PATCH] D103077: [DAGCombine] Poison-prove scalarizeExtractedVectorLoad.

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added inline comments.


================
Comment at: llvm/lib/CodeGen/SelectionDAG/DAGCombiner.cpp:18423
+    KnownBits EltNoBits = DAG.computeKnownBits(EltNo);
+    unsigned NumElts = InVecVT.getVectorElementCount().getKnownMinValue();
+    if (!EltNoBits.getMaxValue().ult(NumElts))
----------------
Is there any chance of NumElts not being a pow2 here?
