The GNU C Info says:

= People frequently have the idea of using RTL stored as text in a
= file as an interface between a language front end and the bulk of GNU
= CC. This idea is not feasible.
= GNU CC was designed to use RTL internally only. Correct RTL for a
= given program is very dependent on the particular target machine. And
= the RTL does not contain all the information about the program.
= The proper way to interface GNU CC to a new language front end is
= with the "tree" data structure. There is no manual for this data
= structure, but it is described in the files `tree.h' and `tree.def'.

Has anyone used this tree approach, is there some documentation on this
subject or can I get some examples of tools that work this way ?
