I tried to compile LLVM with gcc-4.8.1 -flto. I got the following error, when linking lli, llc, opt, or libLTO.so:

`LLVMX86CompilationCallback2' referenced in section `.text' of /tmp/cclv7BYB.ltrans0.ltrans.o: defined in discarded section `.text' of X86JITInfo.o (symbol from plugin)
collect2: error: ld returned 1 exit status

Removing the LLVM_LIBRARY_VISIBILITY attribute for LLVMX86CompilationCallback2 make the link pass for lli, llc, and opt, but not for libLTO.so.

Any ideas why this happens?
