This is a question more for gcc-help. Anyway, the documentation is there http://gcc.gnu.org/onlinedocs/ Anything not documented there is likely to change or be removed in the future, so you should not rely on it. On the other hand, if you find some behaviour that you feel should be documented and it is not, please submit a documentation patch (or at least open a bug report). I would not recommend relying on trunk (specially not during stages 1 or 2) for production code. GCC is under heavy development and it undergoes deep changes during stage1 and that always introduces bugs. Cheers, Manuel.
