--- Comment #7 from Andrew Pinski <pinskia at gcc dot gnu.org> 2011-04-28 03:31:14 UTC --- (In reply to comment #6) > Can anyone provide me with information on the earliest GCC version to support > the builtins for i386? Earliest version is around 3.0.0 and most likely earlier than that. Also note va_args is a special thing and can not really be done via macros on most targets; that includes x86 (alignment reasons IIRC).
