[ANN] DynASM with Lua mode

[Cosmin Apreutesei]

Hi everyone,

This is a modified version of DynASM that allows generating,
compiling, and running x86 and x86-64 assembly code directly from Lua.
It also exposes the DynASM translator and linker to be used as Lua
modules.

Works with Windows, Linux and OSX, x86 and x64.

Code:

Changes from DynASM:

Enjoy!

Great!

This is a very interesting project and I think it will be useful for
many people, thanks for doing and sharing it!

What would be needed to port it to other architectures supported by
DynASM, e.g. ARM? Would following the usage of luamode in dasm_x86.lua
be enough? Maybe some of the language-dependent (C vs Lua) code output
stuff could be refactored into a separate Lua file to ease porting.

Appreciated. Also, this wouldn't had been possible if DynASM itself
wouldn't had been easy to understand, thanks to Mike for that. And
thanks to Peter Cawley for the DynASM doc.

Follow this link:

https://github.com/luapower/dynasm/compare/7d7e130...master

and look at the diff for dynasm_x86.lua. IMHO the changes are small
and fairly easy to do. I don't have other platforms to test, but I'd
be glad to help someone else with questions, code review, etc.

The changes to the code need to solve two problems:
1) output Lua code (search for `luamode`)
2) reset module global state so it can be reused for multiple runs.

If you are only interested in one-shot cmdline-driven operation you
don't even have to bother with the 2nd problem, and the 1st one is
easy.

I have had fantasies of exactly this :-) THANK YOU!

Nice! What a great idea...

I noticed a (probable?) mistake at the end of the code snippet for
"funcs_x86.dasl" - there's a "]]" on its own, without any matching
"[[" earlier on.

Removed, thanks for spotting. Since the feedback's been great I'll add
more tutorial stuff, stay tuned.
