FMAXQV: Floating-point maximum reduction of quadword vector segments
FMAXQV Vd.4S, Pg, Zn.S (SVE2.1 (SME2.1
128-bit SVE
Take the maximum across corresponding active 32-bit float elements from each 128-bit segment of (1), storing the result in (3). For any element where the corresponding predicate bit in (2) is 0, interpret it as -Infinity.
256-bit SVE
Take the maximum across corresponding active 32-bit float elements from each 128-bit segment of (1), storing the result in (3). For any element where the corresponding predicate bit in (2) is 0, interpret it as -Infinity.
512-bit SVE
Take the maximum across corresponding active 32-bit float elements from each 128-bit segment of (1), storing the result in (3). For any element where the corresponding predicate bit in (2) is 0, interpret it as -Infinity.

1024-bit SVE
Take the maximum across corresponding active 32-bit float elements from each 128-bit segment of (1), storing the result in (3). For any element where the corresponding predicate bit in (2) is 0, interpret it as -Infinity.
2048-bit SVE
Take the maximum across corresponding active 32-bit float elements from each 128-bit segment of (1), storing the result in (3). For any element where the corresponding predicate bit in (2) is 0, interpret it as -Infinity.
