Hi Joyee, Incidentally I have just started working on fixing various issues and extending --gdbjit. I think a large part of what you are describing is already available behind this flag. As of yesterday it should work again with optimized code and it even shows maglev IR (see --maglev-gdbjit). I am also working on fixing the startup penalty it has, so we might be able to enable it by default on debug builds.
