...its own module), the stub of g is called and I can generate its code (which use other functions). But I can not find a way to compile g and to update the mapping between g and the new function pointer. When I use recompileAndRelinkFunction, I see that it is not implemented in MCJIT, and when I use getFunctionPointer, I obtain.... a null pointer? I have not investigated further, but probably, having two symbols g in the same MCJIT does not work. And I don't see what I can do at this step? Maybe that I have missed something? Otherwise, I already predict that I will also have one big problem latter: I would...

Hi Andy, We had previous discussions about this, I'd like to state more exactly what features would make MCJIT a replacement for the JIT. After putting significant effort trying to move to MCJIT, I'm currently back with the JIT. This is in a REPL environment where functions are added and removed dynamically and response time is important. The issue is the legacy JIT provides great

Hi Gaël, I'm not familiar enough with the details of the old JIT engine and its event interface to comment on whether or not your changes are appropriate, but I'm not sure anyone is so the patch is probably OK as is. I don't see any obvious problems with it. However, your description of the changes raises a bigger issue in my mind. I'm not sure if you are aware of this, but
