[PATCH] D26297: [AVX-512] Add support for lowering shuffles to VALIGND/VALIGNQ

[Simon Pilgrim via llvm-commits]

RKSimon added a comment.

Add current codegen to trunk to show the diffs in the tests?



================
Comment at: lib/Target/X86/X86ISelLowering.cpp:12215
   if (Subtarget.hasBWI())
     if (SDValue Rotate = lowerVectorShuffleAsByteRotate(
             DL, MVT::v16i32, V1, V2, Mask, Subtarget, DAG))
----------------
Will this ever fire?
