We tried to do this with VFX Forth, which runs under i32, and
has an ARM prototype. There is a Windows version that generates
DLLs, and we have a prototype Linux ****t. A Neon OOP library
is included.
The CPU dependent parts are code generation, start up code and
OS interface. The code generator for VFX is about 5000 lines
of code. The start up and callback interface is a few hundred
lines, much of which has to with insulating the kernel from
OS dependencies at build time. In total the OS interface is
less than 30 coded routines.
The windowing system is a nightmare! I'd really like to
find a library with a C interface (to avoid the C++ name
mangling issues), but we have not yet found a stable one that
satisfies most users. The alternative is to use something
like Bernd Paysan's Minos/Theseus system.
