Squeakers -

There was a recent thread on gnu.misc.discuss: "Looking for an
'assembler generator' utility" that lead to these links. Perhaps Squeak
might be able to leverage this work for native code generation (and to
make Squeak independent of C).

"The New Jersey Machine-Code Toolkit helps programmers write
applications that process machine code---assemblers, disassemblers, code
generators, tracers, profilers, and debuggers. The toolkit lets
programmers encode and decode machine instructions symbolically.
Encoding and decoding are automated based on compact specifications. The
toolkit is a joint project of Mary Fernández and Norman Ramsey."
This work is in ML, but why not Squeak?

"Zephyr: Tools for a National Compiler Infrastructure"
Squeak seems like a great platform to host (incremental) compilers.

I'm not sure what the licensing terms are for these works.

"The trouble is that C was designed as a programming language not as a
compiler target language, and is not very suitable for the latter
purpose. The obvious thing to do is to define a language that is
designed as a portable target language. "

And of course, there is always the GCC technology base.
