The GNU Pasal compiler <http://www.gnu-pascal.de> is maintained as a
separate back-end project. The compiler can be built with gcc-2.8.1 up
to gcc-3.4.x and preliminary support for gcc-4.0 was recently added
(<http://www.gnu-pascal.de/crystal/gpc/en/thread13456.html>). A
regular question is why gpc isn't integrated into the gcc repository.
The answer is that simply the resources fail to maintain gpc on a
daily basis on gcc mainline. Also, flexibility in choosing the
back-end version sometimes has its advantages, dependent on the
platform, given the fact that reported gcc bugs are not always fixed.
Apropos, <http://gcc.gnu.org/backends.html> seems to be pointing to
the wrong page now.
Sorry, it isn't, I mixed up "front-end" and "back-end".
Sincerely,
Adriaan van Os
