--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Created attachment 62368 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=62368&action=edit gcc16-pr114457-wip.patch Untested WIP progress, which compared to the last gcc-patches posted one can now handle also forward gotos across vacuous initializations for C++26 (but it can still mess up -Wimplicit-fallthrough* handling). Next steps are handling of backward gotos across vacuous initializations, then switch jumps to case labels across vacuous initializations and finally trying to deal with it for -Wimplicit-fallthrough*.
