--- Comment #14 from Jakub Jelinek <jakub at gcc dot gnu.org> --- (In reply to Richard Biener from comment #9) > We fail to stream cfun->has_force_vect_loops. Note we don't necessarily have to stream that (and has_simduid_loops), the alternative is to compute it during streaming in the IL - if it sees any force_vect loop, it can set fun->has_force_vect_loops for the loop, similarly for non-zero simdlen and fun->has_simduid_loops. Those two flags are just (pessimistically correct) flags to avoid scanning the whole IL for it, but LTO scans the whole IL anyway...
