Hi Will,
Thanks a lot for your reply.
I tried -mtune=cortex-a53, no error is reported, it works.
One further question, do you have a plan to support Cortex-A57 tuning?
Thanks.
Best Regards.

I believe this is an assembler error, as the assembler only supports
these CPU types on binutils trunk. Have you tried passing
-mtune=cortex-a53 instead?
