[LLVMdev] Objective-C code in lli

[Samuel Crow]

Hi Eric,

You're forcing the interpreter.  That is less compatible than the JIT since fewer people are interested in maintaining the interpreter.  I'm not sure how well it interprets since there has been some work done on it.  Try leaving that option out.  Also, make sure that Clang has all of the proper entries set for emitting LLVM bitcode rather than object code.

I hope this helps,

--Sam
