Andrew Pinski <pinskia at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |NEW Last reconfirmed| |2022-12-02 Keywords| |diagnostic, | |internal-improvement Ever confirmed|0 |1 --- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> --- Confirmed. The following options (and maybe some in the diagnostic messages too) need to be changed/aliased: Wc11-c2x-compat std=c2x Internally the macros: D_C2X STD_C2X CLK_STDC2X CLK_GNUC2X the language name: c-opts.cc: lang_hooks.name = "GNU C2X"; And a few other places. It is early in stage 4 of GCC 13 release cycle but I will leave it up to the C maintainers to see if they want the change for GCC 13 or wait till stage 1 of GCC 14. Confirmed otherwise.
