--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> --- Actually you could exactly what is done for darwin targets to get it working on PIE. Also what do you mean by disabled? Do you mean not doing a PCH for libstdc++ (there is already an option for that; can't remember offhand) or mean execute a sorry for when someone tries it. As I said there is a way to do PCH even with PIE using mmap early on.
