Subject: [PATCH v1 2/8] perf c2c: Display "Total Stores" as a standalone metrics
Date:   Wed, 14 Oct 2020 06:09:15 +0100
Message-Id: <20201014050921.5591-3-leo.yan@linaro.org>
In-Reply-To: <20201014050921.5591-1-leo.yan@linaro.org>
References: <20201014050921.5591-1-leo.yan@linaro.org>
Precedence: bulk

The total stores is displayed under the metrics "Store Reference", to
output the same format with total records and all loads, extract the
total stores number as a standalone metrics "Total Stores".

After this patch, the tool shows the summary numbers ("Total records",
"Total loads", "Total Stores") in the unified form.
