Ping - did this end up getting addressed?

Hi Nick,

I was not aware of it, but it makes sense given the recent switch to ORC2, which has different symbol resolution rules. I am out on vacation this week, but will take a look when I get back and see if I can restore the old behavior. Cheers, Lang.

Looks like somethnig needs updating (either source or the documentation). On Sun, Dec 30, 2018 at 3:28 PM Nick Desaulniers via llvm-dev <_ _llvm-dev at lists.llvm.org> wrote:

https://llvm.org/docs/tutorial/LangImpl04.html has an example where the function foo gets redefined, and the JIT returns evaluation of the latest definition. I thought my code was wrong, but it seems that the binary produced by ninja Kaleidoscope-Ch4 has the same bug.

Granted, my LLVM checkout is from Nov 3 2018 (r346062). Is this a known issue? ~Nick Desaulniers
