[phiall]

When I use o-llvm compiler where -mllvm -bcf -mllvm -bcf_loop=1 -mllvm -bcf_prob=20 param, there is no response, even one day.
Similarly, I hava integrated with XCode 9.2, but there are exceptions when build.
The Exceptions:

1. parser at end of file
2. Per-module optimization passes
3. Running pass 'CallGraph Pass Manager' on module '/Users/i-mac/Files/lhp/wzqqp_ios/frameworks/runtime-src/Classes/LuaAssert/AESEncrypt.cpp'.
4. Running pass 'Bit-Tracking Dead Code Elimination' on function '@_ZNSt3__120__throw_length_errorEPKc'

You have to use the patch in the pull requests.

For completeness, it seems the patch is this one: #76

At least, it worked for me.
