Subject: [PATCH 16/28] perf script: Share code and output format for uregs and iregs output
Date: Thu, 22 Nov 2018 00:35:59 -0300	[thread overview]
Message-ID: <20181122033611.15890-17-acme@kernel.org> (raw)
In-Reply-To: <20181122033611.15890-1-acme@kernel.org>

From: Milian Wolff <milian.wolff@kdab.com>

The iregs output was missing the newline at end as well as the leading
ABI output. This made it hard to compare the iregs and uregs values.
Instead, use a single function to output the register values and use it
for both, iregs and uregs, to ensure the output is consistent.
