README
This is a sample language front end for GCC. This is a replacement for 'toy' which had potential copyright issues, but more importantly it did not exercise very much of GCC. The intent of this language is that it should provide a cookbook of language elements that you can use in any language front end. To this end, treelang is essentially an implementation of a subset of the GCC back end 'tree' interface in syntax. Thanks to Richard Kenner, Joachim Nadler and many others for helping me to understand enough of GCC to do this. Please note, the documentation is not a good model to use for GCC front end documentation. Tim Josling 19 June 2002
