--- Comment #7 from Eric Botcazou <ebotcazou at gcc dot gnu.org> --- > In PR64866 comment 2, Arno said "Visibility in the Ada runtime do not follow > standard Ada rules. In other words, the Ada runtime isn't implemented in > Ada, but in a different dialect very close to Ada, with additional > restrictions.” > > He notes two of the additional restrictions: is there a writeup anywhere of > the language restrictions and usage restrictions like this one? I don't really know, I'm not a specialist of the runtime at all.
