Played with tcc before -- it's fast at assembling, but there's no

That's a good point -- many people (elsewhere) who jump into tcc
think it's a mature compiler that can do everything they wish for
and replace gcc in their lives. But tcc does have a built-in
assembler (IIRC) -- perhaps it is a better starting point than a
An assembler in Lua reminds me of those Forth assemblers...
For OSes that have NX-type settings disabled, calling and
executing a data snippet is trivial, so it's real easy to start
such a project, but a big job to write a fairly complete one. A
thousand or so instructions, and a lot of those are useful for
high performance. AMD just dumped another new instruction set into
gcc the other day, more bit manipulation, and a lot of new mnemonics.
It's pretty niche and hard to drum up support for. Probably the
main coder needs to do >99% of the work. This sounds like
something they throw grad students at.

As for why not C ? C is fine, but I'd prefer to not write out a *.c
file, call gcc, compile it to a *.so, and load it back in -- just
something self contained.
As suggested before, try luatcc.
