Has anybody generated ROMable (as in boot-from-ROM)
code from the 3L C compiler?  If so, how?

I am guesing that the code that comes out of the compiler 
and linker is position independent, and the configurer 
assigns absolute memory location.  Only a guess  -- anybody
know for sure?

Is the generated code generally relocatable (ie uses
relative addressing)?

How complicated is the configurer?  Would it be possible
to write something similar, which places the code in ROM
and the vars in RAM?

Any answers or advice would be greatly appreciated.

Thanks,
