...RC v2 and facing some problems. I am using LLVM 8.0.1. I updated my ORC v1 implementation from 6.0 to 8.0 based on Kaleidoscope example (i.e. using Legacy classes) and that works fine. Now I am trying out ORC v2 apis, based on https://github.com/llvm-mirror/llvm/blob/master/examples/Kaleidoscope/BuildingAJIT/Chapter2/KaleidoscopeJIT.h. I have got it to compile and build. But looks like my compiled code is not being optimized at all. For optimization I am using the PassManagerBuilder class to setup the passes. I use OptLevel = 2. This works perfectly with ORC v1 apis, but with ORC v2 I am not sure wha...

...hat doesn't deal with LLVM. I noticed that llvm-config --cxxflags includes the -fno-exceptions flag. Do I need to throw no exceptions whatsoever in my application to use LLVM JIT? As a minimal example, I modified the code in https://github.com/llvm-mirror/llvm/tree/master/examples/Kaleidoscope/BuildingAJIT/Chapter2. In toy.cpp, I update LogError to throw an exception: std::unique_ptr<ExprAST> LogError(const char *Str) { fprintf(stderr, "Error: %s\n", Str); throw std::runtime_error(""); } and I catch that exception in MainLoop: static void MainLoop() { while (true) {...

Hi all, I'm currently in the process of updating the Kaleidoscope tutorials (first and foremost, the ORC/BuildingAJIT ones), and I've noticed a fair few 404s which are lingering within the current visible documentation. Some of these don't seem to have linked to existing pages for a while. I was wondering if there was a way to set up a check in the buildbot to ensure that documentation doesn't break b...

Hi, I updated my project to LLVM 10.0 today and I am getting JIT symbol resolution errors. I could not find any example or updated tutorial or documentation that describes the new api - as all documentation seems out of date. I paste below some code snippets that show what I am doing: /* global syms is a array mapping names to function addresses */

Hello LLVM developers, I am developing a small project using LLVM. The objective is to provide dynamic loading via JIT compilation of C++ code contained in a (TS) module. For this reason, I would like to return an explicitly raw void pointer (resembling libdl's `void *dlsym(void *, char const *);` as closely as possible) to the compiled result. The MCJIT class offers the most convenient API

...ctly what you want. In the new system you can also perform fine grained removal: It is possible to track and remove individual modules from within a JITDylib.
