I was recently amazed to see Java code being automatically recompiled and injected into a running program. Since modern C++ compilers (eg. LLVM-based) start investigating JIT compilation, I am wondering if there is any work made on this topic.

Update: By "hot recompilation", I mean editing the code, recompiling a specific part of the executable and running it without restarting the program. The common use case would be a game engine with an infinite loop where you would edit some code in the rendering step, and see the changes on the next frame.

What is the research state of hot recompilation for C++? Is there any working implementation?
