- Subject: [PATCH][AArch64][gas] Add -mcpu support for Arm Ares
Hi all,
This adds support for the Arm Ares CPU for AArch64.
It implements the Armv8.2-A architecture with the optional features
of statistical profiling, dot product and FP16 on by default.
Note: Ares is a codename to enable early adopters and in time
we will add the final product name once it's announced.
Tested with check-gas on aarch64-none-elf
Ok for master?
Thanks,
Kyrill
