--- Comment #11 from Iain Sandoe <iains at gcc dot gnu.org> --- I think this needs to be done selectively (I posted some patches which probably need some polish). We have to remember that (much thought I really appreciates Jakub's work on this) this only solves part of the problem - PCH is still not relocatable thus: * Not all targets will be able to do PIE (32b hosts in particular might have trouble to find a free space in the VMA for the PCH) - Certainly, I have not much oconfidence that we can accommodate non-PIE without relocatable PCH on m32 Darwin. * Also it should be possible to have a PIE toolset that generates non-PIE by default - where at the moment you would only get a PIE toolset iff you --enable-default-pie. * so I think that there should be an option to allow PIE tools rather than relying on --enable-default-PIE.. So my guess is that the full answer is: Yes, for hosts that can find a 512Mb or sol space in the VMA that is confidently available - and no otherwise.
