The New Jersey Machine-Code Toolkit can generate the machine-dependent
parts of an assembler from a short machine description. It lacks a
standard syntax for pseudo-ops, etc, into which the instruction
grammar can be plugged. It also lacks an on-disk object-file format.
I have been wanting to remedy these lacks for some time and would be
pleased to work with someone who wanted to put together a retargetable
assembler. (The Toolkit seems mostly to have been used to build
dynamic code generators that go direct to binary, with a smattering of
other applications as well.)
