--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> 2012-05-20 19:14:09 UTC --- This is defined by the ABI. I think if we provide an option for this, we are going to have people abuse this. Also I think the C++ ABIs between MS and GCC not compatible at all since they use different mangling. MS does not follow the cross target/compiler ABI (IA64 C++ ABI).
