I have partially ported the LuaObjCBridge to the iPhone. Most things work but there are still some issues I have to deal with.
There are sections where #defines are defined with-respect-to intel or ppc. Is the ARM chip closer to intel or ppc?
Here is the most relevant section where most of the defines are:
#if defined(__ppc__)||defined(__PPC__)||defined(__powerpc__)
#define LUA_OBJC_METHODCALL_INT_IS_SHORTEST_INTEGRAL_TYPE
#define LUA_OBJC_METHODCALL_PASS_FLOATS_IN_MARG_HEADER
#define LUA_OBJC_POWER_ALIGNMENT
#elif defined(__i386__)||defined(__arm__)
#warning LuaObjCBridge is not fully tested for use on Intel chips.
#define LUA_OBJC_METHODCALL_RETURN_STRUCTS_DIRECTLY // Use this or the code was crashing for me for structs LUA_OBJC_METHODCALL_RETURN_STRUCTS_DIRECTLY_LIMIT
#define LUA_OBJC_METHODCALL_USE_OBJC_MSGSENDV_FPRET
#define LUA_OBJC_METHODCALL_RETURN_STRUCTS_DIRECTLY_LIMIT 8
#define LUA_OBJC_INTEL_ALIGNMENT
#endif
For now I added arm with i386, but I could be wrong
