It generates the parse tree as xml. http://www.gccxml.org/ Do you mean, the entire parse tree in full detail? Would it be conceivable to feed this into a nonfree back-end? Would this mean that nonfree backends could take advantage of our free front-ends? If so, it is very dangerous -- it would open the door to a terrible setback for our defense of users' freedom. Namely, the use of free software as part of compilers that are partly nonfree. I don't remember, but I would guess that is why we have refused to merge it into GCC. Llvm and clang provide natively a way to get the parse tree (and other phases information), and therefore they can be used easily in IDE. LLVM and Clang open the door to the same terrible setback. Since they are not copylefted, their front-ends can be used with nonfree back-ends and vice versa. They are being developed by people who don't care about users' freedom, funded by the worst enemy of users' freedom (Apple). -- Dr Richard Stallman President, Free Software Foundation 51 Franklin St Boston MA 02110 USA www.fsf.org www.gnu.org Skype: No way! That's nonfree (freedom-denying) software. Use Ekiga or an ordinary phone call
