Hi Stanislav, Lang I have a version of objc metadata parser based on LLVM which can handle objc2 metadata from MachO object and bitcode (bitcode version is even swift compatible). I don't know if there is enough interest for me to upstream it. It probably requires some work to clean up the interface and complete it by adding objc1 support and other object format support.

The code in tools/llvm-objdump/MachODump.cpp has requirements beyond being able to parse the Objective-C for the machine it is running on. It must work cross byte sex, with differing alignment, dealing with both Objc1 & Objc2, pointers of the non-native size and not the native addresses and be robust enough to not crash with bad meta data. So while it parses the Objective-C meta data it likely is not a good model for execution. > > Kev > >> On Nov 11, 2016, at 1:26 PM, Steven Wu via llvm-dev <llvm-d...

Hello, Is it possible to execute Objective-C code using LLVM JIT? The original point for my research is this topic on StackOverflow: All selectors unrecognised when invoking Objective-C methods using the LLVM ExecutionEngine http://stackoverflow.com/questions/10375324/all-selectors-unrecognised-when-invoking-objective-c-methods-using-the-llvm-exec
