Subject: [PATCH 12/23] plugins/lockstep: clean-up output
Date: Fri, 28 Jun 2024 13:42:47 +0100 [thread overview]
Message-ID: <20240628124258.832466-13-alex.bennee@linaro.org> (raw)
In-Reply-To: <20240628124258.832466-1-alex.bennee@linaro.org>
We were repeating information which wasn't super clear. As we already
will have dumped the last failing PC just note the divergence and dump
the previous instruction log.
