This is still too tiny ... I am looking for a semi
-practical language
and all modern stuff is ment
for 24+bit addressing.
1) Structures and arrays must be definable. Only + - & | ^ and == <= >=
!= need to be alu operations.
n *n n[i] n[i].foo need be variable types.
2) No symbols permited, only numeric labels. _oooo or $oooo where o is
a octal digit.
This way a simple index look up can find a symbol value.
You don't need register to register operations to support a C compiler.
Can you provide any details of your architecture and instruction set?
It might be feasable to make a port of my Micro-C toolset to it... If
not, it might be feasable to make a port of "C-flea" a virtual machine
I designed specifically to support Micro-C (I've supported some pretty
weird architectures by employing C-flea).
Micro-C is a very small, but reasonably powerful dialect of C - For an
example, refer to the ImageDisk sources on my site ... ImageDisk and all
of it's utilities are compiled with the PC version of Micro-C (as are my
simulators, transfer tools and pretty much all of the other DOS based
tools I've posted).

Btw: If you haven't written an assembler yet, let me know - I've got a
universal table driven assembler generator which I developed to rapidly
produce assemblers for many of the later architectures I supported.
