[PATCH] D94059: [X86] Update X86InstCombineIntrinsic to use CreateShuffleVector with one vector

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added inline comments.


================
Comment at: llvm/lib/Target/X86/X86InstCombineIntrinsic.cpp:244
       SmallVector<int, 16> ZeroSplat(VWidth, 0);
       Amt = Builder.CreateShuffleVector(Amt, Amt, ZeroSplat);
       return (LogicalShift ? (ShiftLeft ? Builder.CreateShl(Vec, Amt)
----------------
This is a (hidden) unary shuffle as well - please can you update ?
