# Max — SMAX/UMAX/FMAX. All are predicated-only (no unpredicated vector
# encoding, in SVE2 either), and destructive: the first source is also the
# destination. The Go API runs them under a synthesized all-true predicate,
# like Abs, and the select peepholes swap the real mask back in.

  asm: "ZSMAX|ZUMAX|ZFMAX"

# Min — SMIN/UMIN/FMIN, the same shape as Max.
