--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
OK, so one reason is that

  if (!can_conditionally_move_p (x_mode))
    return FALSE;

returns false for E_V4SFmode on x86.  min/max detection is based
on fp_cmov expansion for scalar FP on x86 though (with its own
problems, see PR95083).=
