+// On macOS, to support the i386 watchOS Simulator, we will continue building
+// libpthread with an i386 slice for the foreseeable future, even though the
+// rest of the OS has dropped i386. (This also applies to libplatform and
+// libsyscall). Normally, dylibs with any dependency on another dylib need
+// to link libdyld for lazy stub binding. libdyld has many dependencies, so
+// that would create a dependency cycle that leads to the whole libSystem
+// umbrella keeping an i386 slice. Instead, ld64 has changed so that the
+// i386 simulator_support slice of libpthread doesn't use lazy binding and so
+// doesn't need -ldyld.
+// So, to break the dependency cycle, macOS libpthread will not link libdyld.
+// All other platforms (including DriverKit on macOS) will continue to link
+// libdyld.
