CMPNE Pd.B, Pg/Z, Zn.B, Zm.D (SVE (SME

svbool_t svcmpne_wide[_s8](svbool_t pg, svint8_t op1, svint64_t op2)

128-bit SVE

Compare each 8-bit integer with the overlapping 64-bit integer, and set the corresponding predicate bit in (3) to (2) != (1), setting flags based on the resulting predicate.

256-bit SVE

Compare each 8-bit integer with the overlapping 64-bit integer, and set the corresponding predicate bit in (3) to (2) != (1), setting flags based on the resulting predicate.

512-bit SVE

Compare each 8-bit integer with the overlapping 64-bit integer, and set the corresponding predicate bit in (3) to (2) != (1), setting flags based on the resulting predicate.
