[LSF/MM/BPF TOPIC] Compiled BPF and toolchains

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

The discussions we had last year in LSFMMBPF about BPF support in GCC
were very useful, and led to more and better interactions between the
BPF GCC maintainers, the BPF clang maintainers and the rest of the BPF
community.  This helped a lot to achieve better convergence with clang.

We think it would be good to repeat the experience this year with a
session where we could discuss particular topics related to compiled BPF
in general, like the toolchain requirements introduced by the new
features being proposed for BPF (such as supporting segmented stacks,
just to mention a recent one) and how to better support these in both
GCC and clang.
