Subject: [RFC v12 05/65] target/arm: tcg: split mte_helper user-only and sysemu code
Date: Fri, 26 Mar 2021 20:36:01 +0100 [thread overview]
Message-ID: <20210326193701.5981-6-cfontana@suse.de> (raw)
In-Reply-To: <20210326193701.5981-1-cfontana@suse.de>
allocation_tag_mem has a different implementation for
user-only and sysemu, so move the two implementations into
the dedicated subdirs.
