[LLVMdev] Upgrading to llvm-2.9

[Arushi Aggarwal]

namespace llvm {
  class PassRegistry;
  void initializeFooPass(PassRegistry&);
}

using namespace llvm;

namespace {
  class Foo : public ModulePass {
  public:
    static char ID;
    Foo() : ModulePass(ID) {
      initializeFooPass(*PassRegistry::getPassRegistry());
    }

    bool runOnModule(Module& M) {
      M.dump();
      return false;
    }
  };
}

char Foo::ID = 0;
INITIALIZE_PASS(Foo, "foo", "DUMP MODULE", false, false)

I have the above pass written for llvm 2.9. When I load the module with opt,
I get
Unknown command line argument '-foo'.

Am I missing some intialization step.

Thanks,
Arushi
