Yes, AdaCore merge their sources into the FSF's Subversion repository, but they don't do it exactly "routinely". They only merge their changes during the Stage 1 of the development process, when all changes are allowed. During Stage 2, only bug fixes are allowed; they don't normally have many of those. During Stage 3, only release-critical bug fixes (i.e. those for regressions and wrong-code bugs) are allowed, and Ada bugs are specifically considered never to be release-critical. As a consequence, you usually see a large batch of patches in close succession, during only a couple of months, just after the creation of a release branch. The latest such merge happened in january-february 2006 for GCC 4.2. You can browse the gcc-patches mailing list archives on http://gcc.gnu.org to see these patches. The release branch for 4.2 is still some months away. After that, I anticipate to see another slew of patches from AdaCore. > You bring up an interesting course of action as well.

The C++ front-end is written in C :) but the Ada front-end is written in Ada. > Maybe jumping into GCC 4.2 wouldn't be such a bad thing. Indeed. -- Ludovic Brenta.
