commit r15-8570-g1aa49fe0b18deb98e324cee18538d26b46829611
Author: Dhruv Chawla <dhr...@nvidia.com>

aarch64: Add support for -mcpu=olympus
This adds support for the NVIDIA Olympus core to the AArch64 backend. The
initial patch does not add any special tuning decisions, and those may come
later.
Bootstrapped and tested on aarch64-none-linux-gnu.
gcc/ChangeLog:
* config/aarch64/aarch64-cores.def (olympus): New entry.
* config/aarch64/aarch64-tune.md: Regenerate.
* doc/invoke.texi (AArch64 Options): Document the above.
