//     |
//     |  #include "Common/LLVMWarningsPush.hpp"
//     |  #include <llvm/IR/Function.h>

//     |
//     |  #include <vector>
//     |
//     | // Rest of implementation
//
// This enables us to turn on -Werror without fixing all of the places inside
// llvm itself where warning level 3 would normally complain.

// Do some checking to make sure the includes are in the right order
// It is super easy to get this wrong...
