================ Comment at: clang/lib/CodeGen/CGBuiltin.cpp:8431 + CGF.Builder.CreateZExt(CGF.Builder.CreateShuffleVector( + AD, llvm::UndefValue::get(BTy), ShuffleMask), + VTy); ---------------- You can just pass AD twice. You don't need to create an Undef value. It will get optimized later. https://reviews.llvm.org/D45722 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
