Strange warnings - unused mach instructions

I know theses warnings come from sushihangover repo code but i just want to make sure it's ok:

I decided not to comment or remove the declarations until further investigation. We could comment out the variables but I think it's a better idea to leave as-is, so that it can be fixed properly at a later time.

Agree it's better to have warning instead of probable bug. Further investigation needed
