SMAXV: Signed maximum reduction to scalar

SMAXV Dd, Pg, Zn.D (SVE (SME

int64_t svmaxv[_s64](svbool_t pg, svint64_t op)

128-bit SVE

Find the maximum of the active signed 64-bit integer elements from (1), storing the result in (3). If there are no active elements, the result is −0x8000000000000000.

256-bit SVE

Find the maximum of the active signed 64-bit integer elements from (1), storing the result in (3). If there are no active elements, the result is −0x8000000000000000.

512-bit SVE

Find the maximum of the active signed 64-bit integer elements from (1), storing the result in (3). If there are no active elements, the result is −0x8000000000000000.
