--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Oh the "enabled" thing when doing --help is confusing in the case of
-fprefetch-loop-arrays:
fprefetch-loop-arrays
Common Var(flag_prefetch_loop_arrays) Init(-1) Optimization
Generate prefetch instructions, if available, for arrays in loops.


-1 in this case is auto.
