// Test that we register protocol reference metadata. Without registration,
// protocol pointers will not be uniqued correctly and @protocol(NSObject) will
// not match the runtime's pointer.
//
// RUN: %clang -c -o %t.o %s
// RUN: %llvm_jitlink -preload libobjc.A.dylib %t.o
//
// REQUIRES: jit-compatible-osx-swift-runtime
