Is anyone working on porting the GNU cc compiler 
to the transputer? 

I have looked into porting it but GNU's cc
compiler expects a multi-register CPU and since
the transputer is stack based,  there
could be some sticky problems to overcome.

Even if a port is done,  performance of the
output code may suffer since it will be hard to
use the same optimization routines. 

I'm still investigating the effort involved.

Any comments?

Thanks, Steve

This has been talked about since 1985 or so.  I've never seen any
results, nor heard specific reasons why it wasn't done or didn't
succeed.

From what I know of GCC (a bit) and of transputer code generation (a lot),
I'd say they don't match very well.  I'd be very interested in seeing
anybody map the GNU RTL onto the transputer stack.  Very interested...

Please post a summary of your findings.  I'd like to know if anybody
every actually attempt a port, and how things worked out for them.
