+                                   i128mem, X86vpdpbssd, SchedWriteVecIMul.XMM,
+                                   1>,  T8XD;
+  defm VPDPBSSDY  : avx_dotprod_rm<0x50,"vpdpbssd",  v8i32, VR256, loadv8i32,
----------------
There are two spaces before T8XD. Same the next few instructions


================
Comment at: llvm/test/CodeGen/X86/avxvnniint8-intrinsics.ll:1
+; NOTE: Assertions have been autogenerated by utils/update_llc_test_checks.py
+; RUN: llc < %s -mtriple=i686-unknown-unknown -mattr=+avxvnniint8  --show-mc-encoding | FileCheck %s --check-prefixes=X86
----------------
This is only testing half the intrinsics. I think you test the non-S for 128 and the S for 256.


================
Comment at: llvm/test/CodeGen/X86/avxvnniint8-intrinsics.ll:6
+
+declare <4 x i32> @llvm.x86.avx2.vpdpbssd.128(<4 x i32>, <4 x i32>, <4 x i32>)
+
----------------
Are there tests for commuting?
