MISC Readers-
On the subject of compilers for X21 chips...
Does anyone know if the rumored commercial C compiler is a reality?
Supposedly MPE in the UK have a C compiler for stack architectures,
but I don't know if they have been paid to do an X21 port. I suspect,
anyway, the the cost would be beyond most MISCer's budgets.
I've done a little work porting both Small-C v2.0 and Dunfield C to X21. Both
compilers assume a traditional register set architecture that maps poorly
onto X21. The compiled code would be many, many times slower than
native X21 code. It's not clear to me that having a C compiler that
produces slow X21 code is in the best interests of MISC.
However, I do have a Pascal compiler that generates stack machine code.
With a little work it could be made to emit Forth words. With even more
work it could be made to emit X21 opcodes. Is there any interest in a
Pascal compiler?
