From 690b500ef2bb5b84eb09ed9841b3e3c033715103 Mon Sep 17 00:00:00 2001 From: Kyrylo Tkachov Date: Sun, 23 Jun 2024 11:01:41 -0700 Subject: [PATCH] [aarch64] Remove RNG and MTE from -mcpu=neoverse-v2 According to the TRM for Neoverse V2 the Memory Tagging and RNG features are optional configurations of the core and may not always be present. Therefore -mcpu=neoverse-v2 shouldn't enable them. Bootstrapped and tested on aarch64-none-linux-gnu * config/aarch64/aarch64-cores.def (neoverse-v2): Remove MEMTAG and RNG from features. (demeter): Likewise.
