Subject: [PATCH v2 5/7] powerpc/64/build: only include .opd with ELFv1
Date: Fri, 16 Sep 2022 14:07:53 +1000 [thread overview]
Message-ID: <20220916040755.2398112-6-npiggin@gmail.com> (raw)
In-Reply-To: <20220916040755.2398112-1-npiggin@gmail.com>
ELFv2 does not use function descriptors so .opd is not required.
