                  // rewriting the function type creates a new function, so look it up again
                  llvmf = m->getFunction(llvmfn);
              }
              if (dump_module) {

              }

We don’t for the main CPU back-ends because those handle Julia’s address spaces (i.e. they ignore it). GPU back-ends do need to put the pass in their pipeline.
