Subject: [RFC PATCH v2 06/17] objtool: Improve offstr() output
Date: Thu, 19 Jun 2025 16:56:48 +0200 [thread overview]
Message-ID: <20250619145659.1377970-7-alexandre.chartre@oracle.com> (raw)
In-Reply-To: <20250619145659.1377970-1-alexandre.chartre@oracle.com>
offset() formats a section offset into a "<symbol>+<offset>" string.
Improve the output to just "<symbol>" when the offset is zero.
