// Test that we can handle calls to methods on categories.
// The following assembly defines an ObjC class Foo with an instance method
// -foo, then uses a category (Bar) to add an extra instance method -bar.
// The main function calls both -foo and -bar on an instance of Foo to check
// that the calls behave as expected.
//
// RUN: %clang -c -o %t.o %s
// RUN: %llvm_jitlink -preload libobjc.A.dylib %t.o
