Looks reasonable, apart from a glitch in a comment.



================
Comment at: llvm/lib/Target/AArch64/AArch64ISelLowering.cpp:13258
+
+  // Convert 'zext <(8|16) x i8> %x to <(8|16) x i8>' to a shuffle that can be
+  // lowered to either 2 or 4 tbl instructions to insert the original i8
----------------
