From: Kyrylo Tkachov Date: Wed, 27 Jun 2018 14:33:16 +0000 (+0000) Subject: [AArch64] Add support for Arm Cortex-A76 X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=25846b50895262d38e1271bb19def833f9a63182;p=gcc.git [AArch64] Add support for Arm Cortex-A76 The Cortex-A76 is an Armv8.2-A processor with dotproduct and FP16 support. It can be paired with the Cortex-A55 and hence the option -mcpu/-mtune=cortex-a76.cortex-a55 is also introduced. Bootstrapped and tested on aarch64-none-linux-gnu. * config/aarch64/aarch64-cores.def (cortex-a76): New entry. (cortex-a76.cortex-a55): Likewise. * config/aarch64/aarch64-tune.md: Regenerate. * doc/invoke.texi (AArch64 Options): Document cortex-a76 and cortex-a76.cortex-a55.
