Comment at: llvm/lib/Target/AArch64/AArch64ISelLowering.cpp:5322
+ EVT ResVT = Op.getValueType();
+ if (ResVT == MVT::i32 && (OpVT == MVT::v8i8 || OpVT == MVT::v16i8)) {
+ // In order to avoid insert_subvector, used v4i32 than v2i32.
----------------
This could be extended to i16 uaddlv as well, but we can leave that for a followup, I guess.
