[LLVMdev] link problem with llvm-pass

[John Criswell]

Dear Nico,

I believe you need to add LLVMipa to the list of libraries to link into 
your tool.  FindUsedTypes::ID is defined in lib/Analysis/IPA.

I think it would be LLVMipa.a if you added it to LLVMLIBS and ipa if you 
added it to LINK_COMPONENTS.
