Dear llvmers I'm trying to port some code that was written for llvm 3.1 to 3.4.2. I'm having two linking problems and I couldn't find the source of the problem. Usually it is an error for a virtual method not declared. The error starts even when changing llvm version from 3.1 to 3.2. The current line declaring an command line option: ----- static cl::opt<string>

(+Chris, since I assume he wrote this policy - and, as I said in my previous email, I wouldn't mind seeing some justification or just seeing the rule go away & drop the anchors I added previously (or, if we're going to keep it, we could add more anchors & actually get to the point where we're -Wweak-vtable clean & enable that warning)) On Wed, Jun 12, 2013 at 1:44 PM,

I tried to build LLVM with 'gcc-4.8.1 -flto', and when linking unittest programs, I got the following error: /tmp/cc8pMk84.ltrans30.ltrans.o:(.data.rel.ro._ZTIN4llvm2cl15OptionValueCopyISsEE[_ZTIN4llvm2cl15OptionValueCopyISsEE]+0x10): undefined reference to `typeinfo for llvm::cl::GenericOptionValue'
