LuaJIT

Hi,

I just want to share that clink can be build with luajit.

First build luajit using the provided msvcbuild.bat, but before it, comment out the line in msvcbuild.bat that removed the object files, etc. After running msvcbuild.bat, there will be lj_vm.obj. Add that object file to the linker commands for lua project in the clink solution.

Also for lua 5.2 compatibility, add these lines in lua.c (in clink_dll project)

define lua_rawlen lua_objlen

static void luaL_setfuncs (lua_State L, const luaL_Reg *l, int nup) {
luaL_checkstack(L, nup, "too many upvalues");
for (; l->name != NULL; l++) { / fill the table with given functions /
int i;
for (i = 0; i < nup; i++) / copy upvalues to the top /
lua_pushvalue(L, -nup);
lua_pushstring(L, l->name);
lua_pushcclosure(L, l->func, nup); / closure with those upvalues /
lua_settable(L, -(nup + 3));
}
lua_pop(L, nup); / remove upvalues */
}

I attach my build if anyone want to try it.

Note: The dll in my attached build is larger since it's compiled with /O2 (maximize speed).

Very interesting. Does LuaJIT bring anything to the table other than performance? I've not really concerned myself with performance. I would expect calls out to the conhost.exe server dwarfs that of Lua's execution in terms of time.
