[llvm-dev] Is it possible to execute Objective-C code via LLVM JIT?

[Stanislav Pankevich via llvm-dev]

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 <http://stackoverflow.com/questions/10375324/all-selectors-unrecognised-when-invoking-objective-c-methods-using-the-llvm-exec>

Running that example with lli produces the following output:

2016-10-18 21:25:58.332 lli[12970:169282] *** NSForwarding: warning: selector (0x10356a38f) for message 'alloc' does not match selector known to Objective C runtime (0x7fff8e93afb5)-- abort
2016-10-18 21:25:58.334 lli[12970:169282] +[NSAutoreleasePool alloc]: unrecognized selector sent to class 0x7fff7a562130
2016-10-18 21:25:58.338 lli[12970:169282] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '+[NSAutoreleasePool alloc]: unrecognized selector sent to class 0x7fff7a562130'
