Subject: [PATCH 2/4] object-file: refactor corrupt object diagnosis
Date: Wed, 30 Nov 2022 12:30:47 -0800 [thread overview]
Message-ID: <a8c5fcd9f860a0434f974779bae6edf6a8ceeaca.1669839849.git.jonathantanmy@google.com> (raw)
In-Reply-To: <cover.1669839849.git.jonathantanmy@google.com>
This functionality will be used from another file in a subsequent patch,
so refactor it into a public function.
