FMAXV: Floating-point maximum recursive reduction to scalar

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

float64_t svmaxv[_f64](svbool_t pg, svfloat64_t op)

128-bit SVE

Find the maximum of active 64-bit float elements from (1), using a tree reduction, storing the result in (2). Inactive elements are interpreted as +Infinity.

256-bit SVE

Find the maximum of active 64-bit float elements from (1), using a tree reduction, storing the result in (2). Inactive elements are interpreted as +Infinity.

512-bit SVE

Find the maximum of active 64-bit float elements from (1), using a tree reduction, storing the result in (2). Inactive elements are interpreted as +Infinity.
