- Subject: [PATCH][AArch64][gas] Add support for Neoverse N1
Hi all,
This adds support for the Neoverse N1 [1] CPU to gas.
This was previously enabled under the Ares codename, which remains as
a valid option for -mcpu for compatibility reasons.
make check-gas passes on aarch64-none-elf.
Ok for master?
Thanks,
Kyrill
