Is it possible to use lua expression in addressing?
Code:
OK: mov eax,$luaexp
NG: mov eax,[$luaexp]

Since Lua expression works in most places, I want to avoid registerSymbol() or define() because they are verbose (several lines to define a single address).

No, the modrm part is special in that it doesn't look at lua values
but you can do mov eax,$luaexp followed by mov eax,[eax]

Or use a luablock
Code:

{$lua}
return "mov eax,["..luaexp.."]"
{$asm}
