Subject: [PATCH v2 07/14] target/m68k: use gdb_get_reg helpers
Date: Sat, 30 Nov 2019 08:45:55 +0000 [thread overview]
Message-ID: <20191130084602.10818-8-alex.bennee@linaro.org> (raw)
In-Reply-To: <20191130084602.10818-1-alex.bennee@linaro.org>
This is cleaner than poking memory directly and will make later
clean-ups easier.
Signed-off-by: Alex Bennée <alex.bennee@linaro.org>
