commit r16-9290-gfcad6073c3fcf5cfe6bca62dc7c9a0fa354a7401 Author: Dhruv Chawla <[email protected]> Date: Tue May 19 05:45:28 2026 +0000 aarch64: Add support for -mcpu=rigel This adds support for the NVIDIA Rigel 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. Signed-off-by: Dhruv Chawla <[email protected]> gcc/ChangeLog: * config/aarch64/aarch64-cores.def (rigel): New entry. * config/aarch64/aarch64-tune.md: Regenerate. * doc/invoke.texi (AArch64 Options): Document the above.
