[LLVMdev] Help with using LLVM to re-compile hot functions at run-time
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

getSymbolAddressInProcess returning null
Tried that, still didn't work. Then I tried making a direct API call, GetProcAddress(GetModuleHandle(0),"foo") And this works if and only if __declspec(dllexport) is supplied. So it looks like we were both right. On Sat, Apr 2, 2016 at 9:29 AM, NAKAMURA Takumi <geek4civic at gmail.com> wrote: > Have you tried to add dllexport? > > On Sat, Apr 2, 2016 at 4:23 PM
