[LLVMdev] [LLVMDev] Trouble Linking

[Jeff Kunkel]

I am writing my register allocator directly in the LLVM tree, and I am
having trouble linking my project on windows msvc 10.0 compiler. The
error are below, but let me say what I have changed.
1. I added "(void) llvm::createJDKunkRegisterAllocator();" to the
struct ForcePassLinking::ForcePassLinking() method in
"llvm\include\llvm\LinkAllPasses.h"
2. I added "FunctionPass* createJDKunkRegisterAllocator();" to header
"llvm\CodeGen\Passes.h."
3. I implemented "FunctionPass* createJDKunkRegisterAllocator()" in my cpp file.

I know the api change said some items were changed, and it has worked
until the api change e-mail came out. However, I cannot figure out
what I need to change to have this project link.
