You certainly should take a look at the GNAT sources
(ftp://cs.nyu.edu/pub/gnat) which are very readable and
really well commented.


As this is a successfull commercial GCC front-end (for Ada-95) I
think there is no excuse for not studying the sources if you are
interested in how to write a front-end. The Ada sources contain
approx. 147,000 statements and 85,000 lines of documentation.
