--- Comment #9 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
So reading https://gcc.gnu.org/onlinedocs/gccint/Option-properties.html does
make Optimization or PerFunction correct here.
aarch64.opt already has a few with Optimization too:
```
mlow-precision-div
Target Var(flag_mlow_precision_div) Optimization
...
mearly-ldp-fusion
Target Var(flag_aarch64_early_ldp_fusion) Optimization Init(1)
```
