--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> --- (In reply to David Faust from comment #1) > I think this is a bug in the test itself (or with these macros from libbpf). No I think there might be a bug in GCC though I have to double check. cc1: error: result of '8000 << 8' requires 22 bits to represent, but 'short int' only has 16 bits [-Werror=shift-overflow=] ((__u16)(8000) << 8) Hmm, we should have prompted that to int and not warned about it ...
