One of my long term goals is to create a highly portable C compiler backend, with _little_ or no optimization, to ship as "c99" along with the other posixutils I am writing:

As such, after I got compile-i386 working, I was going to work on getting sparse to generate a high-level intermediate language. This intermediate language (IL) is essentially a high level assembly language that knows about simple types. My [non-existent] backend would take this intermediate language -- which could be produced by sparse or a fortran-77 front-end -- and turns it into binary code.
My question: do people think its better to generate this intermediate language from the high-level tree (a la compile-i386), or the lower-level linearized basic blocks?
