Subject: [PATCH v16 19/99] target/arm: tcg: split mte_helper user-only and sysemu code
Date: Fri,  4 Jun 2021 16:51:52 +0100	[thread overview]
Message-ID: <20210604155312.15902-20-alex.bennee@linaro.org> (raw)
In-Reply-To: <20210604155312.15902-1-alex.bennee@linaro.org>

From: Claudio Fontana <cfontana@suse.de>

allocation_tag_mem has a different implementation for
user-only and sysemu, so move the two implementations into
the dedicated subdirs.
