================
Comment at: llvm/lib/Target/AArch64/AArch64TargetTransformInfo.cpp:1025
 
+static Optional<Instruction *> instCombineSVESplatSDIV(InstCombiner &IC,
+                                                       IntrinsicInst &II) {
----------------
nit. I think the name 'instCombineSVESDiv' would be in keeping with the other functions in this file.


================
Comment at: llvm/lib/Target/AArch64/AArch64TargetTransformInfo.cpp:1038
+    return None;
+
+  APInt SplattedAPInt = SplattedConstantInt->getValue();
----------------
nit. Extraneous blank.


================
Comment at: llvm/lib/Target/AArch64/AArch64TargetTransformInfo.cpp:1047
+      {II.getOperand(0), II.getOperand(1),
+       ConstantInt::get(SplattedValue->getType(), SplattedAPInt.logBase2())});
+  return IC.replaceInstUsesWith(II, ASRD);
----------------
nit. Suggest extracting the constant as its own variable to make 'CreateIntrinsic' a bit tidier.
