...he same repl session and call it, it uses the results of the first function call in that repl session: ready> def bar(x) x + 1; ... ready> bar(1); Evaluated to 102334155.000000 I suspect that this has to do with the fact that in ORCv2 we can no longer remove modules meaning that the code in HandleTopLevelExpression can't wrap up by removing the most recent module it added. The tutorial does lookups by creating a function with no arguments names "__anon_expr", calling it, then removing it AFIK and because ORCv2 doesn't allow for the removal part as of yet, my hunch is that the issue is there....

Hi Again, I'm a little confused regarding what is the exact Orc's functions I should use in order to save the functions code in a code cache so it could be later replaced with different versions of it and I appreciate your help. Just a reminder I want to dynamically recompile the program based on profile collected at the run-time. I would like to start executing the program from the

well, as it so seems I need to bother everyone on the list with my pointless newb crap, but here goes. maybe there was a FAQ for all this, but I missed it. well, I am not trying to demean LLVM in any way here, only trying to understand and evaluate things from my POV is all... sorry if at all I seem arrogant or condescending... well, running a linecounter, it is about 223 kloc (c++ ...), +

Hi folks, I'm working on migrating a JIT compiler from the old ORCv1 JIT APIs to the newer ORCv2 ones and am having some trouble getting the code from chapter 1 of the "Building a JIT" [1] tutorial working properly. I have previously walked through the "My First Langauge" [2] tutorial and that went smoothly using the provided JIT class, but using the one from the JIT
