[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added inline comments.


================
Comment at: llvm/lib/Transforms/InstCombine/InstCombineCompares.cpp:5910
+  if (!DL.isLegalInteger(NumBits))
+    return nullptr;
+
----------------
Why not just use NumBits < getMinVectorRegisterBitWidth()  ?
