Andrew Pinski <pinskia at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Known to work| |12.1.0 Known to fail| |11.1.0 --- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> --- Note in GCC 11+, you need to add --help to get which option has enabled or not. Also note in GCC 12+ we get: -fleading-underscore Which means it is not enabled or disabled. Still trying to figure out what changed that.
