Subject: [PATCH 4/9] perf srcline: Skip srcline if .debug_line is missing
Date: Thu, 15 Dec 2022 11:28:12 -0800 [thread overview]
Message-ID: <20221215192817.2734573-5-namhyung@kernel.org> (raw)
In-Reply-To: <20221215192817.2734573-1-namhyung@kernel.org>
The srcline info is from the .debug_line section. No need to setup
addr2line subprocess if the section is missing.
