--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
So, if there is a conflict between options, the backend should choose after
warning the more important from those unless it wants to error, and then
continue, so either change -march=armv8-a to something else, or change
-mcpu=cortex-a57 to something else (or ignore).
