Subject: DPDK LTO and semantic interpositioning
Date: Thu, 25 Jan 2024 20:01:21 +0100 [thread overview]
Message-ID: <6de91a85-7696-410c-84d3-8bde7ab8ed05@lysator.liu.se> (raw)
Hi.
When DPDK is built configured with b_lto=true, it seems like
-fno-semantic-interposition is not passed to GCC.
Is this intentional?
Not providing this flag prevents most cross-unit optimizations for
shared objects.
Best regards,
Mattias
