Hi all,
This patch adds a tuning struct for the Arm Ares CPU and uses it for
-m{cpu,tune}=ares.
The tunings are an initial attempt and may be improved upon in the future, but
they serve
as a decent starting point for GCC 9.
With this I see a 1.3% improvement on SPEC2006 int and 0.3% on SPEC2006 fp with
-mcpu=ares.
On SPEC2017 I see a 0.6% improvement in intrate and changes in the noise for
fprate.
Bootstrapped and tested on aarch64-none-linux-gnu.
Ok for trunk?
Thanks,
Kyrill
