From 9ed6834deacecd0e0671793e1440aa728939b93f Mon Sep 17 00:00:00 2001 From: Kyrylo Tkachov Date: Fri, 22 Feb 2019 08:56:50 +0000 Subject: [PATCH] [AArch64] Add support for Neoverse N1 This patch adds support for the Neoverse N1 CPU [1]. This was supported in GCC earlier through the codename Ares, which it now replaces. -mcpu=ares is still accepted as there's been a binutils release supporting it, but the internal structures are renamed to use Neoverse N1-related identifiers. Bootstrapped and tested on aarch64-none-linux-gnu. * config/aarch64/aarch64.c (ares_tunings): Rename to... (neoversen1_tunings): ... This. * config/aarch64/aarch64-cores.def (ares): Change tuning to the above. (neoverse-n1): New CPU. * config/aarch64/aarch64-tune.md: Regenerate. * doc/invoke.txt (AArch64 Options): Document neoverse-n1.
