I don't want anything analogous to HLA, NASM, etc. I want an assembler that
goes straight to memory.
I am writing a Forth system. I want it to be interactive in the usual Forth
way. This means assembling a function at run-time and immediately being able to
run the assembled function.
What I was doing in HLA was writing a lot of functions in HLA assembly. Then,
during the run-time of the HLA program, pasting together snippets of those
functions to produce new functions. This involves poking values into the code
snippets after they are pasted in, for such things as literal values and
displacement values and so forth. This is a major hassle. It also has a lot of
limitations to what can be done. I'm much better off if I can just assemble the
functions at run-time for the Forth system (which is compile-time for the
user's Forth program).
I would like 64-bit though. My understanding is that there are CL assemblers
available that provide 64-bit, and there is Gambit Scheme's assembler that also
provides 64-bit. I think Racket may get voted off the island. I'm still
interested in Racket for other things though.

There's Noel Welsh's IA32 assembler https://github.com/noelwelsh/assembler. I
guess it doesn't support x86_64 yet.

I don't think there's anything directly analogous to HLA. Noel's work assembles
straight to memory, rather than being an offline assembler. I suppose with a
bit of work (ELF emitter) it could be used instead of gas.

Tony
