I think that you should take a look at the GCC front end HOWTO. Some parts of it are out of date but most of it is quite useful. Studing other front ends is also helpfull. I have made a very small Hello World front end to show what is the smallest program that can link with the gcc middle end. I is not completely documented, but I think that it can be usefull. It is at http://svn.gna.org/viewcvs/gsc/branches/hello-world/
A much more mature example is the treelang front end that comes with gcc. I also think that the fortran front end is a very good reference. > Sorry for any grammar errors, they're unintentional as I just pulled > an all-nighter :). > > Thanks, Sean Purser-Haskell Wen you have more specific question feel free to ask. :) Rafael Ávila de Espíndola
