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.
