There are two LuaJIT functions required for using ljopt and implemented in patches: jit.util.snappc() and jit.util.tablesize(). See commits 40abb90 and 7c317d8. It means that ljopt will not work if these patches were not applied.
But in some cases it may be difficult or inconvenient to recompile with patches, so it is proposed to make an FFI implementation of these functions in case the use of patches is impossible.
