Subject: [PATCH v5 09/13] scripts/decode_stacktrace.sh: Silence stderr messages from addr2line/nm
Date: Tue, 20 Apr 2021 14:49:59 -0700 [thread overview]
Message-ID: <20210420215003.3510247-10-swboyd@chromium.org> (raw)
In-Reply-To: <20210420215003.3510247-1-swboyd@chromium.org>
Sometimes if you're using tools that have linked things improperly or
have new features/sections that older tools don't expect you'll see
warnings printed to stderr. We don't really care about these warnings,
so let's just silence these messages to cleanup output of this script.
