Eric Gallager <egallager at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED CC| |egallager at gcc dot gnu.org Resolution|--- |WONTFIX --- Comment #6 from Eric Gallager <egallager at gcc dot gnu.org> --- g++ no longer supports the -fdump-translation-unit flag: $ /usr/local/bin/g++ -c -fdump-translation-unit -fsyntax-only -std=gnu++98 53360.cc cc1plus: error: unrecognized command line option ‘-fdump-translation-unit’ $ I think I remember some debate on gcc-patches about removing it for gcc8 but I forget the link to the thread... closing as WONTFIX since the flag probably won't be coming back
