[Oopic-compiler-devel] C Compiler

[Neil D. <nd...@us...>]

I've been looking to see if there are any simple open source C compilers
out there that we could use as a starting point for our OOPIC compiler, or
at least use it for ideas etc.

Anyway, I've found one, which compiles to assembler for a stack-based
virtual machine:

  <http://fabrice.bellard.free.fr/fbcc.html>

It uses Flex/Bison for parsing, and implements ANSI C.  It's released under
the GPL licence so there's no reason why we can use any or as much or the
source code as we need.

As it compiles to assembler for a stack-based VM, I thought it may be
pretty close to what we need - we may just have to re-write the code
generation stuff to get it to generate OOPIC "assembler".

I thought I'd post this so we can all have a look at it.  We should only
use something like this if we fully understand how it works, and if it does
actually work!  The code looks fairly clean and well-written (from a quick
browse around the source files), so it all looks promising.

At the very least we can use their Flex/Bison grammar files for parsing
ANSI C and creating the internal representation of the code.

Thoughts?
