[LSF/MM/BPF TOPIC] Compiled BPF

["Jose E. Marchesi" <jose.marchesi@oracle.com>]

[Resending because I don't think the message reached bpf@vger]

Hello.

I would like to propose an activity for the BPF track at LSFMMBPF.

As in previous editions, the purpose of the activity is to do a quick
recap of the current BPF support in both GCC and clang/LLVM and where we
stand, to discuss and clarify any particular issue that may be relevant
to either compiler, and to collect and address comments, requirements
and other feedback from the kernel hackers present.

On the GCC BPF side we would like to pay special attention to the topic
of divergences, as we are nowadays being bugged not so much by missing
features anymore, as it used to be, but by divergences in the support of
certain features between GCC and clang.  Some of these divergences are
trivial to fix just by following clang's behavior as they are found, but
others require discussion and agreement.  Also, we would like to expand
a bit the scope of the discussion to cover a few topics related to the
"environment" where the compiled BPF programs are built.  Examples of
the later are external linking and the inclusion of host standard
headers by BPF programs.

Thanks!
