128-bit SVE

Find the maximum of active 32-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 32-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 32-bit float elements from (1), using a tree reduction, storing the result in (2). Inactive elements are interpreted as +Infinity.
