--- Comment #5 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to Andrew Pinski from comment #4) > Then this is partly a dup of bug 88545 Yes, that would manually transform the find_epi8 case into a memchr call, but Clang doesn't need a manual transform in the library, it does it in the compiler. Tamar's plan to remove the manual loop unrolling in our std::find_if might help here, but I'm not sure.
