Subject: [PATCH v5 06/22] target/arm: use gdb_get_reg helpers
Date: Tue, 14 Jan 2020 15:09:37 +0000 [thread overview]
Message-ID: <20200114150953.27659-7-alex.bennee@linaro.org> (raw)
In-Reply-To: <20200114150953.27659-1-alex.bennee@linaro.org>
This is cleaner than poking memory directly and will make later
clean-ups easier.
