Do you have any sqdmulh-diagnostics.s with negative tests for these instructions?

 defm SQDMULH_4ZZ : sme2_sqdmulh_add_vector_vg4_single<"sqdmulh", 0b100000>;
+defm SQDMULH_2Z2Z : sme2_sqdmulh_vector_vg2_multi<"sqdmulh">;
+defm SQDMULH_4Z4Z : sme2_sqdmulh_vector_vg4_multi<"sqdmulh">;
----------------
This should be: 2Z2Z2Z
And the suffix below should be: 4Z4Z4Z

 }
----------------
Out of interest, why are the multiple and single vector variants of sqdmulh not part of this patch?
