SADDV Dd, Pg, Zn.B (SVE (SME
int64_t svaddv[_s8](svbool_t pg, svint8_t op)

128-bit SVE

Sum active signed 8-bit integer elements from (1), storing the result in (3). If there are no active elements, the result is 0.

256-bit SVE

Sum active signed 8-bit integer elements from (1), storing the result in (3). If there are no active elements, the result is 0.

512-bit SVE

Sum active signed 8-bit integer elements from (1), storing the result in (3). If there are no active elements, the result is 0.

Larger sizes

1024-bit SVE
