Subject: [PATCH v2 3/4] objtool: orc: Skip setting orc_entry for non-text sections
Date: Mon, 8 Jun 2020 08:12:02 +0100 [thread overview]
Message-ID: <20200608071203.4055-4-jthierry@redhat.com> (raw)
In-Reply-To: <20200608071203.4055-1-jthierry@redhat.com>
Orc generation is only done for text sections, but some instructions
can be found in non-text sections (e.g. .discard.text sections).
Skip setting their orc sections since their whole sections will be
skipped for orc generation.
