There is a compiler OXCC which does what you want to do and a bunch
of other things like compile time interpretation and regeneration
of source (including malloced pointers). It can be found by searching
for OXCC1430.ZIP on the web. I wrote the darn thing but it's been
a year since I touched it and I haven't kept track of the ftp sites
that have it. It generates output in an Architecture Neutral Format
and I've included a couple of back end samples. If you think that
it suits your needs I can make the source available for free providing
that you agree to share any improvements with me. It currently uses
an application framework which isn't quite ready for prime time but
does work ok. The compiler compiles itself successfully. If you
use the application framework to call it, you get access to the AST
and all of the symbol tables. In fact a program being
compiled/interpreted can call the compiler and put the result into
the data segment of the first compilation (there is a sample which shows
this). I've already added most of the GCC extensions + others. Java+ is
next.
