--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> --- >From https://gcc.gnu.org/pipermail/gcc-patches/2022-October/604152.html: It's possible further target-specific fixes will be needed; target maintainers should watch out for failures of c2x-stdarg-4.c, the execution test, which would indicate that this feature is not working correctly.
