Dear All, I'm still a newbie, and do not understand very well the machinery behind the GCC garbage collector, in particular the following behavior on a recently svn update-ed GCC trunk. My system is an AMD64/Debian/Sid
cd /usr/src/Lang/gcc # my trunk svn info Path: .

More generally, I have trouble adding a pass basile-analys.c (which does nothing useful yet) which includes its header basile-analys.h which contains struct-ures with GTY(()) so I need to have gt-basile-analys.h generated from basile-analys.h If you really want to dive into my sources (nothing interesting yet, I'm still earning Gcc with some pain), you could get them from http://ours.starynkevitch.net/basile/ggcc-basile.tgz (but this is a home computer on ADSL) - this is an archive of all the source files I added or changed to the GCC trunk Regards -- Basile STARYNKEVITCH http://starynkevitch.net/Basile/ email: basile<at>starynkevitch<dot>net aliases: basile<at>tunes<dot>org = bstarynk<at>nerim<dot>net 8, rue de la Faïencerie, 92340 Bourg La Reine, France
