- Subject: Are there any lua profilers that work with LuaJIT 2.x?

I was wondering if there are any suitable profiling tools for checking
script performance in LuaJIT. I've tried most of the profilers listed in
the lua wiki:
but the main problem I keep running into is that none of them can
properly profile lua C function calls. The main issue seems to be that
LuaJIT doesn't implement the "return" sethook when C functions are
called. What ends up happening is that the final generated report would
end up listing any C function calls as taking up 0 time.
Are there any other alternatives or different approach to consider? How
would one profile lua script performance under LuaJIT when lua C
functions are involve?
