Subject: [PATCH 6/7] powerpc/64/build: only include .opd with ELFv1
Date: Thu, 15 Sep 2022 01:47:45 +1000 [thread overview]
Message-ID: <20220914154746.1122482-7-npiggin@gmail.com> (raw)
In-Reply-To: <20220914154746.1122482-1-npiggin@gmail.com>
ELFv2 does not use function descriptors so .opd is not required.
