It also produces *extremely bad* code. At least for ARM. (I can't read Intel
assembly.) But it's a very interesting idea.
Has anyone seen Lightning? It's a run-time machine code generation library
that allows you to generate, uh, machine code from a MIPS-like abstract
assembly language. Currently it supports ia32, SPARC and PowerPC. It's a bit
clunky but it does seem to work.
I'm currently thinking about a project using Lua for doing very low-level
stuff --- writing an operating system in it, basically --- and so have been
looking into this kind of thing as a hardware interface.
